A swing balancer, a swing-pendulum, a rocker, a rocking chair or a swing-scale - all these are different names for the same type of children's swing.
The balancer is a kind of outdoor swing, fun and safe fun for children of the youngest age. With the support of the mother, one can ride rocking chairs from the moment the child is one year old. So, they can rightly be considered the first swing of children.
The principle of operation of the swing balancer
The principle of operation is simple and based on the overbalance effect, i.e. pendulum swings act like scales. Skating is implemented simply - at the ends of a long bar (lever, balancer or rocker), the center of which rests on the base, children are placed. Pushing off with their feet from the ground, one child rises up, and the second, respectively, falls down. Due to approximately the same weight of children, they are alternately outweighed.
Advantage of swing balancer
The advantage is that the swing-scales allow for the primary social adaptation of the child. Due to the fact that the swing is powered by the efforts of two children, they form teamwork skills and teach cooperation. The need to coordinate their actions develops sociability. In addition, skating trains the vestibular apparatus, muscles and coordination of movements.
Do-it-yourself swing balancer - step by step instructions
A simple design is conducive to an independent device. In terms of material costs, they are cheaper to manufacture than hanging swings for children or Garden swing for adults.
What can a swing balancer be made of (material)
- plastic(plastic). Here, all construction consists in buying a ready-made kit and assembling the purchased parts according to the instructions;
- metal. To make a metal balancer, you must have the appropriate tools and skills. From the tool you will need a welding machine, grinder, drill. For work, you need to prepare steel pipes with a diameter of 5-6 mm. The elements are connected by bolts or by welding. The design of the metal swing balancer is strong enough, but traumatic and difficult to manufacture;
- wood. Wood is an ideal material for making a do-it-yourself swing balancer. Lumber is affordable, easy to process and resistant to environmental factors. And most importantly, wood is a safer material for children, because. it is environmentally friendly, has a low weight (compared to metal), will not harm the child if it falls. Since in a private house, the swing will not be subjected to such intensive use as in a public playground, the use of a tree will be the best choice.
The design of the swing balancer (types, types)
There are several ways to make a swing (device options):
classical. The most common and simplest option is a swing, consisting of a support post and a board fixed to it;
spring balancer. Due to the small swing amplitude, the springs are suitable for very small users. After all, it does not require significant efforts to swing. It is only important to be able to keep balance.
tire balancer. Suitable as a temporary option. Because the tire from a passenger car is not able to withstand this kind of load (it deforms). In addition, balancing tire rocking chairs do not have a significant swing amplitude.
double children's swing balancer. In this case, none of the guys will be left without classes.
with double seat (paired). It requires the creation of an additional margin of safety of the main bar (rocker arm).
rotary (spinning) swing. The design feature is that you can ride them both up and down, and move around the axis (in a circle), like riding a carousel.
How to make a wooden swing balancer with your own hands
We take the classic design as a basis.
1. Drawing and dimensions
Unlike hanging swings, the requirements for which are regulated by GOSTs R 52167-2003 and R 52167-2012, GOST has not been developed for a swing-balancer. This means that there are no recommendations for their arrangement fixed at the level of state regulations. So, you need to be guided by the reviews of users and masters.
Getting started, you need to draw up a drawing of a swing balancer. A visual diagram will be a good help in the work.
Apply to the schematic drawing dimensions pendulum swing:
- the length of the balancer (yoke or main bar). Usually it is 2500-2700 mm. This length is enough to ensure comfortable riding. If the seat is double, then the length of the bar increases;
- support height. The higher the support, the larger the lever, respectively, the greater the load falls on the main bar when skiing. However, the higher children can ride;
- the height of the swing seat from the ground. This parameter has several meanings. Of course, at the bottom point, the height will be zero. In the highest - depend on the height of the support and the length of the bar. It is recommended that the lifting height of the swing should not exceed 1,000 mm. Falling from such a height is considered safe. The measurement must be made at the point where the bar stops perpendicular to the support. The height of the seat is determined by the height of the child and is usually 500-600 mm. This height is enough for the child to easily push off and land, without the risk of injury;
- seat width - 300-400 mm;
- seat length - 450-600 mm;
- handle height - 150-200 mm;
- back height - 200-300 mm.
The last two parameters are especially relevant for kids.
Advice. Each size of the rocking chair is determined individually, based on the parameters of the child.
2. Calculation of the strength of the swing balancer
The load on the swing is calculated based on the weight of the children who will ride. Despite the fact that the swing is usually designed for two children, children can ride in threes (if their weight allows you to create an advantage), or even four. Some are generally attracted to skating while standing. In this case, the balance bar is set in motion by alternately bending the legs. In addition, the swing-balancer is interesting for both toddlers and older children. Therefore, when creating a project of a swing-balancer, it is necessary to ensure a margin of safety.
3. Building materials for manufacturing
Wooden swing balancer can be built:
- from a log - a simpler and faster option to manufacture;
- from a bar. Working with a bar requires skills in carpentry.
The ideal material is oak, but it is expensive and difficult to process due to the high density of wood. Therefore, pine or birch is most often used. The main thing is that its humidity does not exceed 12-15%. Otherwise, the wood will dry out, and the fasteners will not hold firmly.
- lumber: board for seating with a thickness of at least 30 mm, timber for stiffeners, slats for parts, timber for support;
- round blanks for pens;
- metal rod for support;
- hardware;
- wood primer and paint.
4. Installation of the support stand for the swing balancer
Device ways:
use a stump from a sawn or felled tree;
from thick timber. The diameter of the log determines the swing height;
from adjacent logs or beams;
from a beam.
How to make a support for a swing balancer portable.
1. Left post;
2. Right strut;
3. Longitudinal strut;
4. Cross brace;
5. Thrust board;
6. Lid.
By connecting the workpieces shown in the figure, we get a reliable support for the swing balancer with a rectangular base. The received support is mobile. i.e., the swing can be moved. To ensure greater stability of the structure, the support must be made with a weighting agent or attached to the soil surface in any way that will not interfere with its transfer.
How to make a support for a swing balancer stationary.
In this case, the support has no foundation, and the racks are dug into the ground and concreted. Before installing the racks in the ground, they must be treated with an anti-rotting agent (working out engine oil is suitable).
5. Making a balancer (rocker arm)
The constituent elements of the design of the swing balancer are shown in the diagram
1. Swing seating board;
2. Rib;
3. Board limiter;
5. Handle stand.
The dimensions of the balancer are shown in the schematic drawing.
How to make a children's balance beam (rocker) out of wood
- all parts must be sanded to avoid splinters;
- clearly define the center of the board (yoke) to ensure comfortable riding;
- parts must be fastened in such a way that there are no gaps where a child can stick a finger or hand;
- hats of hardware should be drowned in a tree and sanded. It is also a potential source of injury.
Advice. All nodes should be checked periodically. Timely identified and eliminated defects are the key to children's safety.
6. Making the seat, backrest and handles for the swing
The seat is not a necessary attribute, because. you can sit on the edges of the rocker. But their presence will make the fun more comfortable.
The seat for a children's swing balancer can be made:
from soft material(foam rubber, felt). It is appropriate to make such seats removable to clean in the rain. At the same time, they must be firmly installed in their place to avoid twisting and slipping during movement;
from rigid material (plywood, board, plastic). Designate a seat. Usually they go a little beyond the dimensions of the balancer (rocker arm). This makes it possible to take a narrower board for him.
A seat for a swing of scales, as already mentioned, is not a mandatory element. There is also a seatless option. Only for the convenience of the children, you need to cut and grind small indentations along the edges of the rocker. In this case, the seating position is determined by the location of the handles.
Handles are needed in order to hold on to them while moving.
The backrests are designed for babies, but generally exclude the possibility of falling on your back while moving.
7. The device of limiters for a swing
Limiters are called shock-absorbing elements located at the bottom of the balancer. Their purpose is to soften the landing. Because landing from a height of 1 meter on solid ground creates an overload for the spine.
The following are set as limits:
rubber pillows;
from metal elements. They are used mainly on metal swings;
from old tires. The peculiarity is that they are not installed on the balance bar, but on the ground, respectively, they do not weigh down the structure with their weight. Plus, the tire stops ensure that the swing is always raised at the same height. Indeed, over time, a hole appears in the place of repulsion of the legs, which means that the height of the lift increases.
8. Decoration swing balancer (design)
Despite the rather primitive design, wooden swings can be very beautiful. The easiest way to decorate is to paint in bright colors. You can make a balancer in the form of an animal (bear, horse, crocodile, dolphin) or in the form of an airplane or a car. Handles and support can be decorated with figures of cartoon characters. Plywood handles in the form of the steering wheel of a racing car, the steering wheel of an airplane / helicopter - all this will interest the child.
And you can create real masterpieces - a carved wooden swing, which will become not only a means of entertainment, but also a worthy decoration. landscape design garden.
It is better to install a swing balancer in a place that meets a number of conditions:
- the place is well visible;
- the surface is flat;
- the presence of a security zone (1500-2000 mm around the swing). The safety zone is a territory free from thorny bushes, poisonous plants, allergens and honey plants, a source of water and communications.
Conclusion
The fun and enthusiasm of the child will be a worthy reward for the minimum of effort and patience that was put into making a wooden swing balancer with your own hands.
Children's swings are great fun in the summer. In addition to the game, they develop sports skills in the child, teach them to communicate with friends in a playful way. good example such a design are the swing balancer. They are easiest to make with your own hands. It is enough to walk around the playgrounds, shops, copy the drawing you like, and you can get to work. Today we will consider the most common children's swing models, which you may also like.
Having carefully studied the swing device, you can draw a drawing yourself and easily make a balancer rocking chair with your own hands. The design of any design works on the same principle. The movable base is made of a horizontal crossbar, fixed strictly in the center to the rack. For the convenience of children, both edges of the movable crossbar are equipped with seats with handrails. The swing is powered by two children sitting on the edges of the crossbar by outweighing each other while simultaneously pushing their feet off the ground.
The main condition for optimal swing swing is approximately the same weight ratio of children. If the balancer is made of durable material, then even parents with small children in their arms can ride it. Increasing the length of the crossbar, get two seats on both sides so that four people swing at the same time. If you add on both sides under the crossbar along the support spring from the car shock absorber, rolling out small children will be easier.
An example of a scheme for building a swing balancer with your own hands
To make a children's swing, any material is suitable: metal, wood or plastic. Most common in summer cottages are log structures. Having shown a little imagination and skill, the seats can be designed in the form of animals or cars.
The main requirement for the design is that the rocking chair must be perfectly polished and fixed so that the child does not get hurt. Children's swings are designed for a minimum age of 5 years.
Variants of the simplest designs
First, let's look at the simplest swing designs that you can make hastily with your own hands. So, you arrived at the dacha, and the first thing that came to hand was logs and boards.
- From a thick log about 50 cm long, make a rack. How larger diameter logs, the higher the children's swing will swing. Lay the log horizontally, nailing it on both sides along a bar with a section of 50x50 mm. They will ensure the stability of the rack, eliminating the rolling of the log on the ground. From a board 2.5-3 m long, install a horizontal crossbar. To prevent it from moving out when swinging, drill a hole in the center of the board and fasten it to the rack with a metal pin. On the edges of the board, nail two round wooden handles so the kids can hold on.
Blank for swing balancer
The basis of several logs for a swing balancer
- The simplest rack design can be replaced by a stump from a cut tree. Saw a groove 40 mm wide in the center of the stump. Take a small piece of board with a thickness similar to the width of the groove made. Drive the board into the groove with a hammer, fixing it with nails to the stump. Parallel to the board, smash the edges of the stump with an ax so that they do not interfere with the swinging crossbar reaching the ground. In the center of the board, fix two bars across the board. They will play the role of stops, and the crossbar will not move out during swinging. Seats and handles arrange similarly to the previous design.
- If there is no thick log or stump, make a support post from two thin logs 1 m long. Bury them vertically in the ground at a distance equal to the width of the board for the crossbar. Stepping back from the top of the logs 50 mm, drill holes and hammer a metal rod or pipe with a diameter of 12-15 mm into them. You should get a design like a small horizontal bar. Make a balance beam from the board and lay it on a metal jumper. To prevent the board from moving out, attach two stops from the bars in the center or fix it to the rod with an overhead clamp.
Collapsible swing model
Wood is a durable material. If you leave wooden swings outside in winter, they will rot over time. Yes, and in the cold, children will not ride. Here you can turn on your ingenuity, develop drawings and make a collapsible swing with your own hands. It is easy to hide them in a barn in winter, and in summer it is quite easy to move them to any place:
We use a beam to make a swing
To get a beautiful swing with your own hands from a bar, it is advisable to have drawings on hand:
Rocking chair on a spring
An interesting entertainment for a child will be a rocking chair on a spring. In this design, a spring from a car shock absorber is used. Moreover, it can play an auxiliary role in repulsion or completely replace the central support. In order for the swing to function properly, the spring needs to be firmly attached to the ground and the balancer:
- Dig a hole 80 cm deep. Make the width according to the size of the metal frame.
- Weld the frame from reinforcement with a diameter of 10-12 mm. Weld a cross at the bottom, and a metal plate with anchor bolts at the top.
- Install the frame in the pit, fill it with concrete so that the anchor bolts remain on the surface.
- From two metal plates 10 mm thick, make two flanges with a diameter of 180 mm or take factory ones. Weld pipe sections 100 mm long equal to the inner diameter of the spring to the flanges.
- Fix one flange to the foundation with anchor bolts. Fasten the second to the balancer according to the design of the swing.
- Put the spring on the flange pipes and weld them by welding.
When the device of the general mechanism on the spring is clear, develop a drawing and proceed to the manufacture of the swing itself.
Do not mistakenly believe that swings in the country are made exclusively for children to have fun. In addition to the swing, designed for the weight of the child, there is a mass enough interesting options, which will become a wonderful element of landscape design and a place of relaxation.
What to make a swing from?
Traditionally, swings are made of wood, metal, and a combination of these materials. However, a swing seat can be made of plastic, metal pipes, bars, a strong rope, an old chair or a chair without legs. Tires and other waste materials are often used.
The main thing is that it is comfortable and safe to sit on the swing, and the racks can withstand the loads exerted on them.
Often country swings are equipped with canopies made of fabric, polycarbonate, wood, roofing materials. Such a “roof” protects from bright sunlight, you can sit on a swing without the risk of burns.
What are the swings?
Soft swing chair Before building a swing, you should think about their purpose (rolling for children or adults), location (oversized models are inappropriate in small areas), seasonality (it is not appropriate to leave a swing for the winter in the open air in all summer cottages). It is also important to choose a model that fits well into the overall picture of the country landscape.
Swings can be mobile (collapsible) and stationary.
In turn, mobile swings can be suspended or equipped with a prefabricated frame that is installed on the ground.
Do you want to make a children's swing in the country for a child?
Children's swing is great idea how to entertain a child in the country, and the portal site also offers you to familiarize yourself with the information on. If you already have a sandbox, then read the article about building a playground with your own hands -.
You can independently make a swing-balancer, swing-hammock, swing-sofa. special attention deserve designs that are far from the classic representation of the swing design. Unusual swings can be:
And more recently, a swing for disabled children has appeared. The design with a platform for a wheelchair allows even those who, unfortunately, cannot move independently to ride.

Garden swing
We make a hanging swing with our own hands
A frame is not provided for such a swing. We will only make a seat, which we will later attach with chains or ropes to ceiling beams or thick branches.
Have you decided on the design of the swing?
Option 1. The simplest swing is an old tire tied with a rope and hung on a tree. You can also use a chain and fix it with a screw and nut.
Option 2. We place the tire horizontally. We cut 3 or 4 holes, insert metal hooks into them, which we fix with washers and nuts. We thread ropes or chains into the loops of hooks.
Option 3. This is the most difficult option, which will require the skill of owning a grinder. The tire should be cut according to a certain pattern, bent and fixed with long hairpins so that it looks like an animal or bird. One of the ways to make a country swing can be found below.
A swing from a board (a saw cut of a log, a wooden lattice, etc.) and ropes is a classic. It is enough to make 4 holes in the corners of a wide board and thread the ropes.
Instead of a board, you can use an old highchair by sawing off the legs and tying it with ropes.
A metal (steel or aluminum) hoop must be equipped with rope weaving so that a gossamer-seat forms in the center. It is advisable to wrap the edges of the hoop with foam rubber and sheathe thick cloth. And to hang the swing, you will need several strong ropes, metal rings or other fasteners that must be fixed at least four points around the circumference.
As one of the options, you can consider a swing-hoop, inside of which a metal basin is inserted. The edges of the pelvis should firmly hold on to the hoop. Subsequently, the design is easy to disassemble and retrain in a flower garden.
To make such a swing, you will need two wide metal triangles, rivets and the material itself - tarpaulin. We fold it in several layers, stitch it around the perimeter, insert triangles and fasten it with rivets. It remains only to hang the swing on a branch or beam.
For Assembly wooden swing on the racks we prepare the following:
We use galvanized bolts as fasteners for such swings. We refrain from simple screws and nails.
For additional protection material from damage and preserving its natural appearance, we use glazing. We pre-cover them with all the wooden elements of the structure.
Ready swings are hung on a strong branch or fixed on racks with a transverse beam. For Assembly supporting structure use wooden beam.
Lower ends wooden racks treated with bitumen. To fix the racks, it is enough to dig a couple of holes with a depth of about 1 m, install racks in them, fill 20-30 cm of the height of the hole with a mixture of sand and gravel, and then pour concrete.
If you wish, you can make concrete pillars separately and attach a wooden beam to them with anchor bolts. Do as you please. When using the second method, we must lay a moisture-proof material between metal and wood. To give the frame greater stability, we support the racks with braces.
Swing seat mounting options We make the swing itself in accordance with the following step-by-step instructions.
First step. We make supporting arches-clubs. To do this, we use boards with a thickness of 22 mm (best of all from pine) and plywood with a thickness of 12 mm. In accordance with the scheme, we draw a template and cut out 6 clubs.
Second step. On blanks from plywood, we outline the outlines of the core. We make a layer in the middle from a glued shield. In the outer layers of the extreme sticks we create cutouts for the ends of the rope.
Third step. We fasten the parts of the support with waterproof glue. We tighten the support with clamps. We remove them only after the glue has completely dried.
Fourth step. We process the edges of the supports with a grinder, giving them a rounded shape.
Fifth step. Cut out from pine board rounds for rope holders. This is easiest to do with the appropriate drill bit.
Sixth step. We process supports and finished rounds with a primer or weatherproof paint.
Seventh step. We screw metal rope holders through the rounds into the supports, and then we cover the wooden elements
Eighth step. Let's move on to creating a seat for a homemade wooden swing. First of all, we align the picket fence.
Ninth step. Next, drill holes for the screws in each bar. In order for the holes to be made as accurately as possible, we put a corner on the edges of the shtaketin (can be made of plywood) according to the size of the planks with pre-made holes in the right places.
Tenth step. We screw the pickets to the supports. To ensure an even step, we place planks between the planks.
Eleventh step. We fix the armrests to the supports. We also make them from shtaketin. We screw the metal bolts into the end of the slats. We lay a wooden round between the support and the armrest.
Twelfth step. We pass the rope through the holes of the holders fixed in the swing support. We tie the rope on a marine knot, after which we wind a wire, a strong thread or a cord around it.
Thirteenth step. Cut off the free end of the rope with a knife.
Fourteenth step. We pass the rope through the oval hole in the armrests. We rely on the armrest itself on pads mounted on a pair of half rings tightened with bolts.
Fifteenth step. We wrap the rope around the thimble for cables and tie it with a rope.
In conclusion, it remains to hang the ring from the Alpine carabiner, fixed to the crossbar of the support or a thick tree branch. Your swing is ready!
Metal swings are also easy to make with your own hands.
First step. We cut blanks from pipes. You need to make 2 two-meter side racks, a 1.5-2-meter crossbar, as well as 4 pipes of arbitrary size for the base (2 pipes will go to each side).
Second step. We clean the pipes from burrs with a metal sandpaper or a file.
Third step. blanks for the base at a right angle.
Fourth step. We weld the racks to the finished base, and then weld the crossbar to the racks.
How to install a crossbar on a metal swing Fifth step. Getting Started earthworks. It is necessary to dig 4 holes with a depth of 80 cm.
Sixth step. We insert metal beams into the finished pits a little longer than the depth of the pits.
Seventh step. We fill the recesses with beams with concrete mortar. Concrete can be made independently from a part of cement, a part of crushed stone and two parts of sand. Add water to the dry mixture and mix thoroughly until a homogeneous mass is obtained.
Eighth step. We leave the concrete for about a week to gain strength.
Ninth step. We weld the hooks to the crossbar. Anchors can be used to make hooks.
Tenth step. We weld the swing frame to the metal beams.
Eleventh step. Attaching the seat.
On this homemade metal swing is ready. You can test and accept for permanent operation.

Swings are not just for fun. For adults, they calm the nerves, improve mood and put thoughts in order; especially if, swaying, contemplate the clouds in the sky. Children and teenagers on a swing train the vestibular apparatus, develop coordination of movements, and, as they say, feel physics with their whole body. Schoolchildren who know how to swing well on a swing, as a rule, do better and quickly grasp such difficult concepts as, for example, the moment of inertia of a body.
Making a garden swing with your own hands is a simple matter. Who in childhood did not swing on a plank suspended from a branch of a tree on ropes? Or didn’t he flounder into a river or a pond, swinging on a bungee? And having at your disposal a certain amount of material, a simple tool and not quite crooked hands, you can build a corner of relaxation in any situation, which in its action is not inferior to a rock garden arranged according to all the rules, see fig.
country grace
Street and yard swings are placed where there is a place. At the dacha, it’s also, in general, not in abundance, but for yourself it’s worth figuring out how to collect country pleasures in one edem: and the place is saved, and, if we relax, then the beds, from which the hands are in calluses, eyes didn't callous. Here, as usual, every man is his own master. However, there is a very good universal option: hang a swing for giving in a pergola, see fig. If it is, of course, strong enough for this. Dig more and equip a decorative pond nearby - and a do-it-yourself paradise is ready on less than 1 hundred square meters.
About metal swings
Their own swing is most often made of wood: it is more familiar, cozier and easier to work with. But if, say, the whole world equips a playground, then a stronger and fireproof structure is already needed, so that the tomboys do not have to pull up every now and then, and it was difficult to damage the swing by a hooligan, which, alas, will not be transferred. In such a case, in Fig. below is a drawing of a classic, so to speak, yard swing made of metal: pipes, corner, strip, wire rod, with a canopy. In the future, we will pay more attention to wooden swings, except for those cases when metal is necessary for strength: for a sports corner for a teenager, etc.
Note: there are also cases when metal as a structural material for a swing is chosen according to other criteria. For example, at pos. 1 fig. on the right - a forged swing. Their production requires high skill, and it is very expensive to order, but the prestige is obvious. But on pos. 2 in the same place - a metal swing from the scraps of the channel. For those who know how to deal with welding machine and the grinder, their construction is a matter of half a day, and the bright coloring masks the utilitarian nature of the material.
The best for children
Swinging on a hanging swing does not begin immediately. Toddlers, who have just learned how to rearrange their bottom two properly, are just right to ride on a pendulum swing. Which, by the way, also develops motor skills and strengthens the musculoskeletal system. Parents who built their children's swing-pendulum with their offspring are soon convinced: abrasions on the knees and elbows, broken noses, roar and resentment from both have noticeably diminished. Although, of course, still not without it. But the swing will help children develop reasonable caution and common sense, preventing serious injuries.
It is known how the swing-pendulum works. Shown in Fig. the option is interesting in that as many as 11 nails are required for metal fasteners:
Details marked with (!), are made of hard, small-layered deciduous wood - oak, beech, hornbeam, walnut. The ends of the pendulum axis can not be turned to a perfectly round one: it is enough to plan it more or less evenly so that they fit into the nests with a slight interference, and shake the board several times, they will run in. If the fibers in the axis and support posts are oriented mutually perpendicular (which is elementary to observe by cutting them out of one board), then the swing will last for many years, and the rubbing surfaces will soon become mirror-smooth and durable, as if machined from steel.
The pendulum swing can be made portable, so that, say, it can be brought to the veranda for the winter. 2 ways for this are shown in the same place, pos. a and b. According to method a, the ends of the racks are concreted in an unusable tire; method b is obvious and simpler, but both riders can fall sideways along with the swing. By the way, many other benefits can be derived from old swing tires; we will return to them later.
Swings for older children are made suspended, as for adults (see below), with some features:
- The supporting beam of the swing is made from a bar with an extension to which a ladder leads, see fig. on right.
- Even better, if there is enough space, put an additional support lower on the side, so that a horizontal bar is also obtained, see fig. below. In this case, it is preferable to make the entire sports corner, except for the bar of the horizontal bar, from profile pipe, then the whole structure is stronger, cheaper and technologically simpler.
- Hanging a rocking chair for children who already know how to swing is best suited for a 2-2 rope scheme (see below). Then it will be possible without the risk of pinching, or even breaking a finger with a chain, swinging, it takes your breath away. And correctly chosen materials and the design of the suspension will not allow you to “turn the sun” and dive down from its highest point, or turn into a projectile fired from a sling, not being able to group for a landing, like acrobats.
Note: when choosing or designing a swing, do not neglect safety precautions! When rocking in full swing, the speed of the rocking chair at critical points of the trajectory exceeds 50 km/h! Accordingly, the result of a breakdown or fall from a swing will be equivalent to an accident at the same speed.
There are also swings for newborns and babies. There are many benefits, but medical equipment. It is strongly not recommended to make such a swing yourself, and you need to choose purchased ones and use them only as directed by a pediatrician.
For babies from about six months old, whose eyes are already looking meaningfully (this means that their vision has formed and they see clearly), a children's swing for little ones will be useful, see fig. on right. They cost a lot, but it’s very easy to make similar ones yourself from pipes, PVC or propylene, and cutting plywood, see video:
Video: baby swing for kids
Do not forget to just plug the ends of the pipes with foam: at this age, a finger crawls into a small hole, and you want to put it in there. They swing the child in such a swing, holding the suspension with their hands; in the apartment, the same one is suitable as a crossbar plastic pipe, the weight is small.
Note: it is the swing that is most often the basis of the children's corner. What else is needed for it, and how to put it all together, requires a separate description in parts. For an example, you can watch the following video:
Video: playground with swings in the program "Fazenda"
Adults and all-all-all
Now it is appropriate to ask: how is the swing set for the whole family? So that it would be comfortable for adults to swing, and for children to like it too? It is quite possible to find a compromise: the seat should be double-backed, but not very massive. The seat is strong enough so that a large child can stand on it. We take a chain suspension, because rope with such a load will stretch. Its scheme should provide a fairly easy swing without outside help, limiting the angle and speed of the swing, and a long swing after it.It is desirable to make a family swing out of wood for the above reasons: they are more comfortable, no complex tools or special equipment are required for manufacturing. It is also highly desirable to get by with 1-2 standard sizes of lumber, and what is cheaper is an ordinary edged board. For durability, the workpieces are impregnated with biocides (antiseptics) and water repellents (water-repellent agents).
Since the swing is not a residential building and will dry out very quickly in the air, it makes no sense to spend money on expensive branded products. As a biocide, used motor oil (working out) is suitable, and a water-repellent agent is a water-polymer emulsion or, instead, PVA glue or water-based tile, diluted 3-5 times. The blanks cut to size are impregnated first with mining, and after 3-7 days with an emulsion.
Drawings of a family swing of this "classic" type are shown in fig; the length of the legs is given based on their penetration into the ground by 0.5 m:
Their peculiarity is that they are built entirely of boards, without the use of more expensive timber, as can be seen from the material sheet, pos. 2. On pos. 3 shows how the supports are adjusted before assembly: a crossbar board is used as a slipway. The legs, cut to size and at an angle (see below), are applied to the stock, bred to the desired width (at the same time, the accuracy of cutting is checked). Then a workpiece of the lower spacer is superimposed, set parallel to the slipway at the distance of its ends from it, and marked for trimming in place. From scraps of the lower spacers make the upper ones.
Note: in fig. on the right - a method of marking the blanks of the legs, based on an angle between them of 30 degrees. Markers on a steel bench square are made from several turns of soft wire with bent ends.
Swing of our own design
You may have a question: how to make a swing completely on your own? Schemes, drawings are good, but if there is already material (for example, left from the construction site), which is clearly enough for a swing, but does not fit into this design? And I don’t want a typical product, I want something of my own. Finally, in fig. at the beginning it is clear that the most luxurious original swing is generally obtained from dead wood and waste from pruning the garden. How to make a beautiful, comfortable, durable and safe swing out of all this? Well, let's get started. Sequence order:
- Dimensions;
- Foundation and method of attachment to the ground;
- Carrier frame;
- Suspension methods and designs;
- Suspension units;
- Rocking chair, she is a seat;
- Ways to hang a rocking chair.
Finally, consider a few more non-trivial designs and special, but arranged on the basis of ordinary, special-purpose swings.
Dimensions and proportions
The dimensions of the swing are considered, firstly, based on the width of the park bench seat for 1 person - 60 cm; the minimum value is 40 cm. Take a little more seat height above the ground standard height chair 40 cm, so that, on the one hand, you can swing without touching the ground with your feet and at the same time, stretching your legs, you can slow down; on the other hand, it was even more convenient to sit down / get up. Usually they take 50-55 cm, but in fact they customize it for themselves by adjusting the height of the suspension, see below.
Note: for a paired swing with a longitudinal buildup, the height of the suspension of the board (boat) is taken 0.7 of its length. For landing and disembarking, then a platform is needed, and for a rocking chair, a smoothly acting brake (suddenly someone is muddied on it, or he / she gets scared and panics), actuated by the operator from the ground. Therefore, paired swings with longitudinal buildup are almost never used in everyday life.
Suspended swings consist of a supporting frame (2 support posts + crossbar), a suspension system and a rocking chair, it is also a seat. The distance from the edges of the seat to the side supports is taken at least 150 mm with a chain suspension type 2sh-4 or 4-4 (see below), for any other chain suspension from 250 mm, for ordinary rope suspensions from 350 mm, and for any suspension with 1 attachment point at the top - at least 0.7 of the total height of the suspension system. These requirements are based on the fact that for any swing, lateral swinging is inevitable, and touching the rocking chair on the support is unpleasant and, with strong swinging, is traumatic. That is, if we have, for example, a 40-cm seat suspended on ropes, then the span between the supports should be at least 35 + 40 + 35 = 110 cm.
The distance from the seat to the crossbar should be no less than the height of a person on a swing, so that, firstly, you can swing while standing, and secondly, so that, suddenly getting up, you do not hit your head. It is taken within 190-220 cm, depending on the available material.
The angle between the legs of the side supports is taken 30-40 degrees; most often - 30. Then, if we take blanks in half the standard length of 6 m, i.e. 3 m, then, taking into account the depth of the legs and the thickness of the workpiece on the seat, it will just be possible to stand up to his full height. In addition, the area occupied by the swing is reduced.
Note: the thickness of the material of the bearing parts is taken on the basis of a 3-fold overload during rocking. For a quality wooden beam, this will be from 150 mm in height, and for steel pipes - from 40 mm in diameter or side of the square.
Ground anchor
The legs of a wooden swing are either dug into the ground 1 m or more, or concreted to a depth of 0.5 m. 60 cm. In both cases, the ends of the legs before being installed in the pits with a margin of 15-20 cm in length or impregnated bituminous mastic(40% bitumen and 60% white spirit or solvent), or spilled with bitumen heated almost to a boil, and, barely cooled down, sprinkled with sand; this method is better protected from decay.
To pour bitumen, bricks are placed under the leg so that the butt can also be poured. It is poured in a thin stream, for which it is convenient to heat the bitumen in an unusable tin with a drawn-out spout. Having poured over one side, the leg is immediately turned over and poured over the other side, trying to also flow onto the butt. Sand is sprinkled in the same order.
WITH metal swing the situation is more complicated: a pipe that is thin compared to a log or a bar can eventually either wriggle out of the ground or break on the concrete itself, tk. here, when swinging, loads are concentrated. Therefore, metal street swings common use must be made with support frames in the form of a solid triangle and concreted into a trench, then laid in it metal beam will take on a significant part of the effort and unload the legs.
The legs of the swing without additional supporting elements, like those shown above from the channel, are concreted to a depth of at least 1.2 m, regardless of the depth of freezing in the area, then the channel will be able to transfer part of the loads to the concrete. Ordinary metal swings are best tied at the bottom with an additional supporting frame and attached to the ground with anchors at least 1 m long, see fig. This, by the way, will allow, if necessary, to return the land for economic use without any problems.
Frame
Country swings are most often made on a frame of 2 A-shaped supports connected by a transverse beam. Sometimes, if the swing is equipped with a hard awning, the frame is made on 4 pillars with a canopy, see below. In hot sunny places, where an awning is needed all summer, this gives some savings in material.
IN Lately the frame on λ-shaped supports is becoming increasingly popular, on the left in the figure:
During construction, it saves wood in a whole beam, which is significant at current prices for lumber. But this swing is only for adults: when swinging in full swing, the supporting beams may not withstand - the wooden ones will break, the metal ones will bend. By the way, it is impossible to make a λ-frame from ordinary structural steel, it will bend immediately. We need very expensive special steel.
Frames with a traverse (in the center in the figure) are known to everyone: a swing on a bitch is what it is. Specially traverse frames are made for acrobatic swings with the 1st suspension point of the rocking chair; on them, having mastered the swinging technique properly, you can write out intricate pirouettes. In this case, the wood on the frame is taken in double thickness, and on the concreted ends of the legs there must be firmly attached crossbars.
A kind of traverse frame - metal mobile. They are made of high-quality steel, loads, moments, center of gravity, etc. mechanical wisdom is accurately calculated. In a similar way make popular (and very expensive) swing chairs, on the right in fig.
wooden frames
Log
The most spectacular and in many cases inexpensive swings are obtained from logs. It is not necessary to take debarked and rounded: as already mentioned, trimming waste and dead wood will go. The frame from the latter, if the trunks are still strong and powerful, does not need additional reinforcement, pos. 1 in fig. Swing frames made of commercial logs, especially if they are mobile, i.e. not dug in and not concreted, it is necessary to strengthen with struts, pos. 2 and 3. The same amount of material is needed in the latter case, but the frame closes the sky less. The question is, why are the frames not deepened? In order not to spoil the lawn or paved area, in fig. it is seen.
If the swing is dug in or concreted, then the most economical and durable frame is like a Chinese swing, pos. 4. Although such a swing has long been known in Russia; they were often made in birch forests, tying the tops of trees in pairs. "Russian-Chinese" swings can also be made shallow by providing an additional frame at the bottom. A drawing of such a design is given on the next. rice: legs - logs or square bars, crossbar - timber 180x80, lower frame - from boards 150x40.
bar
An ordinary, unprofiled wooden beam makes it possible to build a swing greater than a log. It is easier and cheaper to make a swing with a permanent canopy for hot countries from a bar, pos. 1 in fig. A conventional frame on A-shaped supports made of timber (pos. 2) will also turn out to be simpler and stronger: under the weight of the rocking chair, the legs compress the crossbar (pos. 3) and the more the swing is loaded, the stronger the frame is held. In the frame of the "Russian-Chinese" swing from a bar at the top, just like for logs, only 1 fastening unit is needed, pos. 4, and the device for a canopy over a swing made of timber on A-shaped supports is also not difficult, pos. 5.
Moreover, the crossbar from a bar can be taken the same as on the legs, i.e. reduced section (100x100 mm), if it is reinforced at the ends with overlays from the board, and the hanging points of the rocking chair are placed close to them, pos. 6. Then the moments bending the crossbar will, as it were, flow into compressive legs, and the tree holds the compressive load well.
To enhance this effect, the crossbar is sometimes placed below the tops of the supports, pos. 7, but the gain in strength is illusory, but the extra fasteners are striking, and it costs money. Using this principle, it is better to cut off the tops of the supports and additionally secure the crossbar from above with overlays, pos. 8. Then it will be possible, if the crossbar is 150x150, and the legs are 200x200, to make the crossbar extensions up to 1.5 m, and hang a children's swing on the ropes to them, attach a ladder with a slide, etc. You will get a family swing-sports corner with a material consumption of only a little more than for one swing.
And another question: is it possible to replace the beam with a board, say, 150x40? It is possible, as shown in pos. 9, only extensions can no longer be made and the height of the supports will have to be limited to about 1.8 m. The swing will be just as strong, but much cheaper than the beam. Well, it will take more work - to mark, cut, stitch.
Note: the “classic family” swing described above is even more economical, but their legs must be concreted, otherwise the plank frame will be fragile. And shown in pos. 5, 6 and 9 are mobile, they can simply be placed on the ground or on the floor.
How to put a frame?
The swing crossbar must be horizontal, otherwise the rocking chair will wobble unpleasantly on any suspension. expose it bubble level difficult and troublesome, hose is not much easier, but laser level- the builder of planes, of course, they just don’t keep it on the farm.
You can set the crossbar of the swing using one of the oldest leveling devices - the Egyptian plumb line, see fig. It fell out of use in ancient times due to low accuracy, but it will be enough for a swing. As a lower load, you can use a bucket of sand, and, in addition to the usual construction plumb line, any iron - a bolt, a nut - will go to the top.
Hangers and pendants
The suspension of the rocking chair determines the convenience, comfort and safety of the swing. This rather complicated node should:
- Prevent rocking within safe limits as little as possible.
- Gently absorb rocking energy if rocking speed/angle is out of range.
- Ensure rocking without jerks and with as little sideways wobbling as possible.
- Acrobatic suspension should provide the same in 2 planes.
Rocker suspension schemes are indicated by formulas of the form n-m-k, where n is the number of suspension points at the top, m is the number of intermediate suspension points, and k is the number of them on the rocker. It is somewhat similar to the wheel formulas of steam locomotives, but this is a pure coincidence: for a steam locomotive, m cannot be equal to 0, since denotes the number of driving axles, and for a swing - easily.
Some types of rocking chair suspensions are shown in Fig:
Suspension type 1-2 with a soft flexible rocking chair (not shown in the figure) is called a flying trapezoid. Hangers of types 1-m-k are used in swings on traverses. Garden and country swings are most often hung in ways 2-4 (the easiest), 2-2-4 (does not swing excessively) and 2sh-4 (you also won’t swing much and no wobbles).
Special mention should be made of the 4-4 suspension. It’s not actually a swing: how can you swing on such a thing? However, it is sometimes used for original garden benches (on the left in the figure):
For some, a little erratic swaying is soothing. But most often, swing arbors are suspended in the 4-4 way, on the right there. It's a matter of taste, some people like it. The eastern lords of the past, and even of the present, they say, they simply thrive in such in the company of their concubines.
Chain, rope or pull?
Hanging a swing on a rope is the easiest and, if you know how to knit some sea knots (see below), does not require expensive additional fasteners. But the rope, as you know, stretches, and the spiral layer does not limit the swing in any way. Therefore, firstly, it is better to hang the simplest children's summer swings on the ropes, pos. 1 in fig. below. Secondly, take the rope with a cross lay, see fig. on right. It has a lot of internal friction, which is why riggers do not like it (the efficiency of lifting mechanisms decreases), but for a swing, this is exactly what is needed so that the unreasonable child does not arrange somersaults for himself. The diameter of the nylon cross cable for swings is from 24 mm.
Chain hanger, pos. 2, expensive, but in terms of the totality of characteristics it is optimal in all respects: the chain is strong, its wear is immediately visible, it almost does not slow down a slight buildup, and extinguishes excessive due to friction in the links. However, due to the latter circumstance, the smallest in a swing on chains for adults can seriously pinch a finger; for children's swings, small-caliber chains are taken.
The rocking chair on rigid rods (pos. 3 and 4) is suspended, as a rule, on bearings. It sways very smoothly, without the slightest wobble, and, as they say, a mosquito will swing on it. But such a swing without additional measures safety are dangerous: crashing headfirst into a stone fence or curb at a speed of under 60 km / h is no longer an accident, it is a tragedy. Therefore, on the site, swings on hard rods for children should, firstly, be equipped with a rocking chair with a fence, as in a swing for kids, pos. 3. Secondly, it is still impossible to let a child on them without adult supervision.
In public yard swings on bearings, a swing limiter must be provided - who knows how to get in there and how he knows how to swing? About a simple limiter from a pipe (see fig.), the rocking chair beats, which is unpleasant. In good branded swing models with rigid rods, bearing suspensions are made with a built-in hydraulic brake, which operates on the principle of viscous coupling of cars with an AWD drive, but such suspension units are expensive.
Sometimes rocking is also limited by connecting rigid rocking rods to the frame with segments of chains, pos. 5. But, generally speaking, this is not the best way out: due to the different mechanical characteristics of the suspension links, even a small and quite safe swing on such a swing occurs with noticeable jerks.
Note: there is also a whole class of luxury swing suspensions on systems of balanced levers, springs, hydraulic shock absorbers. It is clear that it is expensive and not to do it yourself.
Suspension units
Critical swing suspension points are attachment points. They have very large alternating loads, they are subject to abrasion. A small burr on the rubbing surface of the attachment will give very noticeable jerks when swinging. Therefore, the choice of the design of attachment points must be approached with all responsibility.
The cheapest, but also the worst option is S-hooks, pos. 1 in fig. Huge loads are concentrated in their crossbars, the probability of sudden destruction is high, therefore, such an attachment is only permissible for swings-benches suspended no higher than 0.5 m and whose design allows you to barely sway.
The most reliable fastening is on clamps with carabiners, pos. 2. The main load in them falls on the top of the crossbar beam, which is absolutely safe. It is only necessary that the carabiners have safety teeth and an anti-friction insert: the suspension rod sliding in the eye of the carabiner is already an emergency mode in case of excessive swinging.
Reliable clamps still spoil the look of the swing, so fastenings are most often done on eyebolts, pos. 3. Indispensable conditions for their maximum reliability - the bolt must pass through the crossbar, under the nut, regardless of the material of the crossbar, a steel washer must be placed at least 60 mm in diameter and 4 mm thick, and the nut must be tightly locked. Spring washers of all types during rocking do not prevent the gradual spontaneous loosening of a single nut!
The reliability of the eyebolt is absolute - there are large stresses on the neck of the eyebolt (ring). Absolutely reliable are slightly more expensive U-hooks and shackles, pos. 4. Under the mustache of the hook, a blind hole is drilled in the crossbar and it is inserted tightly there. Not being able to straighten even a little, the hook will withstand an incredible load, because. the destruction of the metal begins with microdisruptions in the bonds between its crystallites.
The eyebolt, U-hook and, to a lesser extent, the shackle significantly weaken the deadbolt, since the concentrated force applied from above tends to break it just where the beam is weakened by the hole, and the fastening pin, when swinging, seems to “gouge” it. The washer weakens this effect, but does not eliminate it completely. As a result, where it would be possible to get by with a 100x100 mm solid beam, you have to put 150x50 mm, and based on the buildup in full swing and all 200x200 mm.
They are conspicuous, but ideal in all qualities through fasteners with an overlay and an upper suspension, pos. 5 and 6. Shear forces from them spread freely to the sides along the beam and tend not to break, but, on the contrary, to compress the hole, as if it does not exist; the beam now becomes an equivalent solid. In addition, although such a suspension looks like a 4-4, it is kinematically equivalent to a chain 2-2-4, but dampens excessive buildup even better and smoother. If the suspension with overlays is rope, then between the carabiner and the fire (loop) of the cable you need to put a solid ring, pos. 6.
Also, the rings connect the branches of the chain suspension 2-2-4. The upper branch is welded to the ring or soldered with hard solder, and the lower ones slide freely along it, pos. 7. Only then will the 2-2-4 chain hanger acquire the desired kinematics.
Rope hangers are good because they allow you to easily adjust the height of the rocking chair, but, made "in a chain", require quite a large number expensive fasteners, locking and adjusting parts and assemblies, pos. 6,8 and 9. However, all of them, for one easily accessible to self-manufacturing exception, can be replaced by sea knots of the corresponding purpose. The reliability of marine knots has been tested for thousands of years maritime practice, and their complexity exists only in conventional representation.
You don’t need to know 200-400 knots, like a boatswain of a sailing fleet, or at least 20-40, like a current yachtsman, to build a swing, 7-9 is enough for everything, see fig:
A - an anchor knot, or a fishing bayonet, for attaching a cable to a carabiner with an anti-friction gasket or an intermediate ring. Up to 5 hoses (turns) can be carried into the eye. A simple mark is applied to the running (free) end of the cable and the running end is connected to the stretched end with it, shown in the red frame. The mount holds until the cable rots or the eyelet rusts. The anchor knot is not tightening, it is not difficult to untie it: it is enough to remove or cut the brand that tightens the ends.
B - bed knot, also non-tightening. Suitable for the upper suspension of temporary, say, for the weekend, children's swing.
B - a bayonet with a run-out, the same as B, but for adults.
G - stop knot, or figure eight. For the lower attachment of a children's swing through the holes in the board.
D, G - sealing the end of the cable with a turnip and a simple disk knob. The same as G, but for adults, and the tails of the cable do not hang out. Although, in general, it is better to fasten a rocking chair on ropes to the bottom without knots at all, as described below.
Z - net knot, for tying 2 ropes crosswise anywhere without cutting.
And - this is how a loose loop is knitted on a solid rope. You can hang an umbrella, a soda siphon, adapt a shelf or something else.
Note: there are also simple knots for tying 2 ropes, the same or different, for example. weaving knot. However, it is strongly not recommended to assemble a swing rope suspension from pieces.
It remains to solve the issue of adjusting the rocking chair on the ropes. To do this, you need 2 trimmings of a durable hard board from 30 mm (oak, beech, elm, walnut), from which running, or hanging, rope stoppers - lufers are made, see fig. on right. Such gizmos regulated the tension of the rigging vintage sailboats, and nothing - the oceans swam across, America-India opened. Ufers are used in conjunction with the rocking chair suspension method described below.
Rocking chair and its fastening
A rocking chair for adults is, in general, garden bench without legs. They choose it to their taste and on the back with a fifth point. From below, an adult rocking chair is reinforced with a pair of transverse bars, and eyebolts or U-hooks are inserted through their ends, as in pos. 4 drawings of the "classic family" swing at the beginning. Fastening at any point of the top, as in pos. 1 fig., is extremely unreliable. The centrifugal force during swinging should compress the rocking chair and press it against the supports, and not stretch and tear it away from them.
Children are very fond of swinging on flying trapezes, pos. 2 in fig. below. You can make this yourself from a tarpaulin, reinforcing the ends with wooden planks inserted into pockets sewn on the bottom and providing eyelets. But you can’t put eyelets for curtains, they are weak. If there are no sailing eyelets at your disposal, you can sew on their substitutes from a steel ring and a harsh, properly wired or resinous thread, pos. 3.
Children's rocking chair from a board with a two-point suspension, pos. 3, it is not recommended to do it by any means, there is a high probability of overturning. If we make a rocking chair at 2 points, then from logs, as in pos. 4, and hang the rocking chair from the board at 4 points, passing the cable through the holes, pos. 5.
However, the best rope suspension for both children and adults is a loop in the grooves, pos. 6. For adults, the lower support bars of the rocking chair are made wider, with an offset of 100-200 mm. They do not interfere, on the contrary, with a slight swaying, you can put a book on them, put a can of beer, etc. And suddenly there will be a transverse buildup, they will also serve as good shock absorbers. The suspension in the grooves is absolutely reliable, it is elementary assembled and disassembled. Adjusting the height of the intermediate points with slings allows you to change not only the height of the rocking chair, but also the kinematics of the suspension within a fairly wide range.
Tire swing
Perhaps the most favorite swing for children is made of tires. The reasons here are not only psychological or ergonomic, a rocking chair made of tires is an excellent shock absorber in emergency cases, and an adult master dad is an excellent rocking material. An unusable tire can simply be hung on a bough, pos. 1 in Fig., from its trimming, a flying trapezoid is obtained without any particular difficulties: the presence of a strong rubber of steel cord in the mass makes it possible to do without eyelets. The whole tire will go to the rocking-nest for collective gatherings of small fry, pos. 3. When two or three swing each in their own way, the trajectory of the rocking chair-nest on a suspension 1-3 or 1-4 makes a person who knows mathematics and physics well scratch his head thoughtfully.
Finally, from tires cut and folded in different ways, single rocking chairs are obtained not only for children, but also for adults, pos. 4-6. The popularity of tire swings is so great that some sports toy and children's goods companies produce, especially for swings ... square tires, pos. 7! It remains only to exclaim after the author of "Tartarin of Tarascon": "Has anyone ever heard of something like this?"
Curiosities, but to the point
Since we are talking about funny swings, let's touch on some of them, but quite suitable for their intended use. For example, swing-hammocks, on the left in the figure, although the hammock is already a recumbent swing in itself. There is probably something about wiggle with additional degrees of freedom that the owners like. In any case, there will be no harm.
The device in the center will surely appeal to children, but it is impossible to name it without sinning against Russian grammar. Swing, don't swing. And the author posted a photo of what is on the right with a note: the easiest way to recycle an old car. The commentary was in English, so it's quite possible that in many Western countries, getting a car to a junkyard or scrapping it is worth a lot of trouble. And here the large inertia of a heavy rocking chair allows, having swayed, to sway for a very long time, the canopy turns out by itself, and the soft sofa will not reduce comfort.
Not those but the swing
Finally - about the swing, the direct descendants of the children's swing-pendulum, but quite adult. And not for fun, they help to cope with arthritis, osteochondrosis, sciatica without expensive treatment. Reviews of doctors are positive.
It is made by hand from simple improvised materials.
