Homemade screw lock with a secret for the garage - instructions and drawings. Tricky DIY locks Homemade garage lock with a falling key

Hello, master! How can you design a cunning internal lock for a garage at your dacha? If it's easy, can you give me some advice?

Roman, Moscow.

Hello, Roman from Moscow!

You know, the main thing is not to outsmart yourself. Among our shabby circles there is a story about how a certain man hung a sledgehammer in his garage, which, if you don’t know about it, when opened, should hit the burglar in the forehead. Naturally, the man one day, drunk, forgot about this, with all that it entailed.

There is no trick against scrap except another scrap. Everything can be opened, another thing is that sometimes this takes a lot of time, and a thief does not always have this time.

I already talked about some tricks on my website. Therefore, perhaps I will repeat myself a little.

I consider several methods to deter burglars to be the most effective.

First. When two more gate leaves made of reinforcement (ordinary grille) are installed behind a regular garage door. And a simple padlock. But it is hung not from the outside, but from the inside. And it is covered from the outside with a welded plate. That is, it is impossible to see it, even if the outer gate is opened. And you have to open it by putting your hands behind the plates, by touch.

We did this and always laughed when the burglars, having opened the first gates, did not know what to do next. Moreover, all the garage things were already visible through the bars.

But this is not always feasible for a number of reasons.

Second option. A regular rack and pinion lock (with a plate key and not a round key). And a sheet of rubber about a centimeter thick (approximately 10/10 centimeters in size) is attached to one gate leaf from the inside. With a couple of bolts. The point is that sometimes, without opening the lock, bad people bend the metal of the gate and try to saw through the lock tongues with a hacksaw blade. The blade rests on the rubber and cannot cut. In my garage one day they knocked down the outside padlock, peeled back the trim and started trying to saw off the top tab. But then they spat and finished.

Third option. When an external conventional padlock is covered with a welded box so that it is almost invisible. This ensures that the lock can be knocked down or cut down only after cutting the box. And this is somewhat difficult in the absence of access to sources electric current, even if you have an angle grinder.

I’m not talking about video surveillance systems, but one client I know had a dummy video camera installed at an inaccessible height. He says it helps.

In addition, you can use a regular rail inside the garage, like a latch, which moves freely inside the supporting brackets and is closed in one position and open in another. To open, a key is used in the form of a pin, at the end of which a plate hangs on an axis. The owner first trains on open door and, if necessary, sharpens and adjusts the key for free opening. What is achieved by inserting the key to a certain depth into a hole made in the metal of the door (gate), up to the mark made on the key.

Such a lock is characterized only by the presence of a hole on the outside, which means nothing to the burglar.

For one client, we installed a custom hardened pentagon head bolt from inside the garage. This bolt could only be unscrewed with your own wrench and nothing else. The whole difficulty lies in the manufacture of such a bolt. That is, it was possible to go through the door, but the gate was locked from the inside with such a bolt. Thieves could steal small change, but not the whole car.

Since all these descriptions may not be entirely understood, but drawing a bunch of sketches takes a long time, I will limit myself to depicting for clarity only one version of a rack and pinion lock.

By way of explanation, I’ll add that the hole in one of the gate leaves is about 10 millimeters, the key shaft itself is about 8 millimeters. The hanging plate hangs freely on a small axis. When the key is inserted, both the plate and the key shaft form a single straight line. After the key is inserted to the mark on the rod, the plate lowers under its own weight and falls into one of the slots on the rail. If not the first time, then move the key, it will definitely hit.

To prevent the rail from falling out, it goes in one direction until it stops, and in the other direction until it reaches the welded bracket. In total, you have to weld two brackets and one corner stop. After opening the rack lock, the second half of the gate is opened with a pair of latches, which are located in the upper and lower parts of the gate leaf. But this is already elementary.

Closing is done in a similar way; when the key is pulled out, the plate itself acquires the desired position and the key can be removed freely.

Lubricate the rack with liquid machine oil, otherwise called a spindle.

In this entire structure the most important detail- plate, its length is main secret lock, and since this size is not visible from the outside, it is almost impossible to guess it.

Of course there are plenty of other options. But enough said. You can't tell everything.

Other questions on the topic of garages.

Even the most expensive, and therefore complex, shop locks are not a problem for an experienced burglar: the only difference is the time required to open them. Non-residential, detached buildings are at greatest risk from unauthorized entry. And if from a small country house If there is nothing special to take away, then, for example, a garage is the object of increased attention of intruders: there is something to profit from in it.

Mortise and padlocks are not a barrier for them. Universal master keys, proven techniques - locking devices in standard version They don't protect you from car theft. Another thing is a mechanism made independently, the secrets of which are known only to the master. In terms of increased reliability and security level, a screw lock is of interest.

Its undeniable advantage is its non-standard design. structural elements"secrets". Even if you open/close a sample in the presence of a stranger, the latter will only be able to understand the principle of operation, determine the type, but will not be able to select a master key or a method for opening such a garage lock.

Screw mechanism design

“People's craftsmen” have developed several versions of locking devices of this type. But their components, as well as the principle of operation, are identical: the difference is only in individual details.

• Frame. It is selected or from finished product, or manufactured on machine tools. It is only necessary to make a deep groove in the metal and cut a thread in the channel along which the locking element will move.
• Bow. It is present only in mounted models. The invisible lock is built into door leaf or attached in an overhead manner to reverse side doors, so only the key hole is visible on the front. On the lower part of the bow, a chamfer is made, into which the screw rests when screwing it in until it stops. The difficulty of manufacturing is to correctly determine its location.
• Threaded rod. A screw lock differs from other types of locking mechanisms precisely in this detail. During the process of closing/opening, the rod moves along the channel and locks/unlocks the bow.
• Key. It is not much different from the analogues that come with other types of store-bought or homemade locks; The difference is in the “working” part. Its configuration depends on the design features of the locking rod.

There are several schemes for assembling screw mechanisms. The configuration of the case (horizontal/vertical), its shape, and the size of the shackle are details that do not affect the functionality of the lock. The degree of its secrecy is determined by the peculiarity of the working part of the key.

Option 1

A slot is made at the end of the rod, and the end of the key is a longitudinal protrusion that coincides with the groove; or vice versa. The easiest lock to make with a secret screw type.

The disadvantage is that such constipation can only cool the ardor of a lover of profiting from other people's goods. For a professional, it is not an obstacle - it can be opened with a regular screwdriver with a flat blade or a type of pliers (platypus), or tweezers.

This mechanism can be improved by changing the shape of the end part of the rod. It is made square or rectangular. The downside is that it is much more difficult to make a key for it.

The advantage is that it is extremely difficult to open such a lock with a secret. For example, a steel tube flattened on the sides can serve as a master key. But it's not that simple.

• The tube still needs to be selected according to the diameter of the hole in the housing.
• You will have to tinker a lot to give the working part of the master key the proper configuration. After all, even if you can still see the “head” of the rod, it is unlikely that you will be able to accurately determine the size of its edges visually.

Option 2

When choosing a lock scheme for a garage that you can assemble yourself, it is advisable to focus on this engineering solution. The fundamental difference from the previous ones is the increased degree of secrecy. It is impossible to select a master key for such a mechanism. And although skeptics claim that it will be possible to open it with a strong wire, in practice this cannot be done. If the screw is tightened all the way, it is impossible to unscrew it, given the small radius - checked.

The peculiarity of the design is that a hole of small depth is drilled at the cut of the rod. This is a seat for the pin located at the end of the working part of the key. It is difficult to turn, and therefore home craftsmen prefer to weld a thin steel pin to its head. Although in this case, as an option, you can do exactly the opposite. What's the secret"?

The hole is drilled at a certain distance from the center of the rod, and this interval is chosen arbitrarily by the master. Even having seen the “socket” in the channel of the housing, it is impossible to determine its diameter, as well as the amount of displacement from the longitudinal axis of the screw.

If you study all the articles on this topic and exchanges of opinions on forums, you can find other options for screw mechanisms. But all of them, as a rule, are modifications of the samples noted above (for example, instead of one thrust pin there are two). There is no point in inventing something more complex, since you will need special equipment + skills to work with it. Therefore, talk about hand made It’s not necessary - you can’t do it without the help of a professional.

It remains to add that homemade screw-type security locks are better than store-bought counterparts, no matter what managers and advertisers claim. The arguments are as follows.

• The mechanisms are not produced in a single copy; only to order. Otherwise, you will have to constantly rebuild the technological equipment, and this will make the cost of any lock prohibitive. And since many of them are similar, then burglars have already developed opening techniques.
• The secret of a self-made locking device is known only to the master. Selecting master keys will take so much time that the very idea of ​​getting through a door protected by such a lock will seem absurd even to a professional; too much risk. This means that the mechanism will fully fulfill its security function.

When making a lock for a garage (or other protected facility) with your own hands, do not forget that its main secret is its non-standard design. Therefore, all drawings, diagrams, descriptions, which are easy to find in various sources, should be regarded only as useful information. You should not blindly copy the mechanism - the guarantee of the reliability of the locking device lies in the originality of its design!

A garage is built not only to protect the vehicle from negative impacts external factors, but also in order to protect it from theft. Of course, no garage can give a complete guarantee that the iron horse is safe, so we can talk about a degree of protection that will largely depend on the strength and reliability of the garage lock.

When starting a conversation about garage locks, it should be noted that, like most devices, they can be of several types:

• Mounted.
• Mortise.
• Rack and pinion.
• Invoices.
• Mixed devices.

One of the main criteria for the differences between these devices is how they were made, namely whether we are talking about factory products or whether they are homemade garage locks.

Advantages and disadvantages

It is impossible to say that some of the castles are definitely better, since each of them will be superior to a similar castle according to certain criteria, but in some ways inferior to the other.

Note! The question of choosing a lock is often determined by its price.

If you want to purchase a decent and reliable factory device, then you need to be prepared to pay quite a lot of money, because in this case we will no longer be talking about a simple factory stamping, but about a mechanism assembled by hand by a professional. In general, a number of common points can be identified in the differences between factory products and homemade products.

• If you are interested in quality and reliability, then you will have to pay decent amounts in both cases.
• In both cases, if you want to save money, you need to be prepared for losses in quality, and here we should not forget that the price for this may be the safety of the vehicle.
• The installation of the device must be approached very responsibly, remembering the basic rule - best protection the one that is not visible.

Types and principle of operation of locks

Among the locks on the market, there are several types.

Mounted

One of the most common types of locks is a padlock. The entire mechanism of this device is hidden in a suspended housing. Locking is carried out using an arc (or pin) inserted inside. For the device to work, on locked doors it is necessary to install special eyes into which the arc is inserted and thanks to which the locking occurs. This type technical devices has one negative quality that calls into question all its advantages, namely openness. Such locks are hung from the outside, as a result of which attackers can have access to it and use a master key to open it, or simply knock down the lock. It follows that such a lock can only be used as additional measure protection, with combined use several options of locking devices.

Rack lock

This is another common option for making locks. It is mounted already inside, and locking is carried out using several sliding rods. The lock is opened using a special key, which, passing through the well, pulls out the bolts. The design of this type of lock is somewhat more reliable, but it can be broken by sawing through the locking elements or simply picking up the key.

Mortise lock option

This type is characterized by difficulty of installation and relatively low reliability. In addition, manufacturers often unreasonably inflate prices for such products. It can also be said that the use of a lock of this type is possible only as an additional security measure.

The above locks are Garage Doors In most cases, they are factory-made, but they can also be made independently if you have certain metalworking skills. However, it is worth saying that it would be more preferable to manufacture locks and constipations of a different type.

Pinwheel

This name was popularly given to a lockable system that operates on the principle of a deadbolt. This version of the lock has a simple design and can be made by hand. The principle of operation of this device is that special eyes made of, for example, metal or wooden beams. In the center of the gate, a rotating bolt is mounted on a through bolt, which is activated by turning relative to the center. The ends of the turntable fit into the eyes, thereby reliably locking the doors from the inside. Thus, there are no elements of the lock from the outside, making it almost impossible to break into.

Espagnolette

This is another DIY option for locking your garage door. Its simplicity and at the same time reliability and efficiency allow it to be used in a large number of cases. The bolt is a metal pin that moves inside the eyes. It is usually mounted on inside garage door. This type of lock works on the principle of a valve. Almost anyone can install it, without the use of highly specialized tools.

This type of locking device can be called a type of latch, with the only difference being that the latch, as a rule, moves in a horizontal plane and is used with a single-leaf gate design. Constipation is for swing gates, are metal rods that move vertically inside special eyes on the gates. In order for the locking to take place, a couple of holes about half a meter deep must be made in the ground under the rods. For greater strength and reliability, metal tubes of suitable diameter can be driven inside these holes, which can be concreted.

In conclusion, it can be noted that do-it-yourself garage locks (which were listed above) are mainly used if the garage is either built into the building of the house, or is surrounded by a fence and has a second exit, because the most effective locking occurs only from the inside.

Video

This video demonstrates the design and operation of a homemade garage lock:

The main advantage of security locks made with my own hands, is that by their nature they are unique. Professional burglars do not stand still. They have long studied many of the working patterns of factory locks and can easily open almost any one.

However, the protection of the garage, made using the owner’s individual technology, can sometimes be very difficult to figure out. And this circumstance will ultimately lead the attacker to a dead end.

When approaching the manufacture of such protective equipment, it is necessary to have good and durable materials. Otherwise, even a very unusual lock will simply be torn off due to the insufficient strength of the materials from which it is made.

Another important point, on which it depends The effectiveness of the future castle lies in the fact that it should be designed according to its own design and preferably in a single copy. Often, a non-standard approach and wild imagination, and in some cases, a complete lack of logic, bring a lot of help.

It should be understood that thieves who earn money in this way on an ongoing basis also have a certain ingenuity. And the more original the design of the lock, the sooner the thief will be at a dead end.

IMPORTANT. The simpler a garage lock looks, the less likely it is that a burglar will be able to figure out how it works.

Options for garage mechanisms with a secret

There are several approaches to making a security lock for a garage:

ATTENTION. It should be borne in mind that opening and closing the lock in front of strangers should in no case reveal the principle of its operation.

Most simple view The secret for the garage is mechanical. So, let's look at a few of these options:

• key making unusual shape and type. It is worth understanding that today the design of almost all factory locks is not a special secret. In addition, through various online platforms you can order almost any master key for a particular lock. Therefore, making a key of a unique type will have a very good result;
• castle with special device. Often you can make a lock that doesn’t require a key at all. Its operating principle will be that it will open only by a pre-thought-out combination of turns of the device;
• You can also combine a standard lock with a lever lock. This option is very effective, simple and reliable.

Additionally, it should be noted that a DIY garage lock must not be visible from the street, and at the same time have an armored bolt. There are electric locks of this type that can be controlled from a distance. Are different high level efficiency, since this lock cannot be opened by anything.

Also, an electric lock can be combined with a conventional mechanical one. In this case, there will be two levels of protection. The burglar will first try to break the padlock, and even if he succeeds, he will be faced with another obstacle in the form of an electric one. And here it will be difficult to cope.

REFERENCE. Most high protection has a hidden electric lock with radio control. A key fob with a specific code is used as a key. When you try to open such a lock, the receiver determines that the entered code matches the one that was originally set and opens the lock.

For additional protection The code can be changed every day, that is, a one-time password is used. This approach is called anti-scanning.

You can purchase such a lock or make it yourself. However, if purchased, its price will be no less than 9,000 rubles. RF. A one made by hand will be cheaper, but not everyone will be able to cope with this, due to the fact that it will require quite deep knowledge in electronics and programming.

Making a clever design with your own hands: step-by-step instructions

So let's imagine step by step instructions for the manufacture of a garage lock with a bolt that will move using a special key that has original features.

First you should prepare all the parts necessary to build a homemade castle:

1. At the very beginning, you need to make the very basis of the castle. It is a metal plate with a thickness of no more than three millimeters and a diameter of about 10 millimeters;
2. We cut out two more plates from the same metal, which will serve as overlays. Their width and length should be 22 and 120 millimeters, respectively;
3. the prepared overlays must be bent in a vice;
4. Let's start making the bolt for the lock;
5. Next, we prepare a tube for a key with a diameter of about 10 mm. One end of the tube should be cut at an angle of 60 degrees.

Assembling a lock with a secret:

1. First you need to weld the pads to the base.

   REFERENCE. If parts are deformed during the welding process, they must be straightened later. If the distortions are small, then they can be removed during the installation of the lock on the gate.

2. Drill four holes in the corners of the plate. They are necessary to attach the lock to the gate.
3. The guide tube should be inserted into a hole with a diameter of 10 millimeters made in the plate. Apply the bevel to the overlays.
4. Weld the tube perpendicularly to the base of the lock.
5. Next, insert the bolt of the future lock between the linings.
6. Install 2 screws into the valve itself, at least M4 in size and about 8 millimeters long. These screws will limit the movement of the valve. Spring washers should be placed under their heads.
7. Next, we proceed to preparing the key.

So, the key should be about 8 millimeters in diameter and about 150 millimeters long. One of its ends should be bent at an angle of 90 degrees, and on the other side a cut should be made at an angle of 60 degrees.

The secret of the lock is that it makes a hole for the key in the bolt either lower or higher, and the gap can be 1 millimeter. In this case, the castle will have a large number of ways to establish “secrecy”. To do this, the wearer has the ability to change size 12 in sizes that are acceptable.

Conclusion

Thus, a garage owner with at least a small amount of imagination and desire can easily provide reliable protection your property and vehicle.

Of course, you can resort to installing the latest locks with complex mechanisms or even putting the garage on guard. However, in practice, many protective measures are not as effective as they are advertised.

Leaving vehicle in the garage, we, first of all, protect it from adverse weather conditions, and also hope for its safety from theft. Tell me, have you ever thought about what exactly your car is protecting? Certainly, important factor are the materials from which the building is made, but the main role is still assigned to the lock on the gate. But even in such a simple question as choosing a shutter mechanism for a garage, a large number of nuances can arise: which one to choose - factory or homemade, cheap or more expensive? Our answer - choose homemade options. We will tell you why and how to make homemade security locks for the garage in our article.

The choice of a garage door lock manufacturer faces all owners of garage buildings, and it is quite small. You either choose a factory product, or create a unique mechanism that is suitable specifically for your garage.

It's no secret that many car enthusiasts would rather buy this product in a store. However, if you buy a stamped lock for a garage, you are not sure that thieves will not be able to find a suitable master key for it. In addition, the quality of such bolts is often poor. Factory-made shutter mechanisms that have the appropriate quality, guarantee, and are assembled by hand are classified as products in a fairly high price category. Do you agree to pay such funds?

A homemade garage lock is a guarantee that thieves will prefer not to have to worry about solving the design and will bypass your garage space. If drawings of factory products can, if desired, be found on the Internet, then manual option– is unique, and finding the key to it is very problematic.

Main conditions of safety

Do-it-yourself garage locks must meet a number of requirements:

• the mechanism must be completely hidden from the street;
• It is advisable to use high-quality materials; it is better if the constipation is armored;
• If possible, make combination homemade locks with a secret for the garage.

We study the classification

In general, homemade garage locks can be divided into two large groups– independently manufactured and altered. Self-production constipation is advisable if the appropriate components are present: quality materials, equipment (milling, lathes), equipment for steel hardening. Experience working with metal will also be important. Otherwise, even the most original lock will be easily opened.
The best option would be to remake purchased locks or individual components. This method will allow you to do without special equipment, while creating a single version of constipation.

By design, garage door shutter mechanisms are divided into:

• mortise;
• mounted;
• invoices;
• rack and pinion;
• pinwheel;
• combined.

Each type has its own positive and negative sides, which should be taken into account during selection.

Padlocks

This type is considered to be the oldest and, unfortunately, unreliable type of constipation. Despite the fact that it is recommended to use hardened steel for their manufacture, such a lock can be easily knocked down with a hammer or sledgehammer, since the entire mechanism is located outside. In addition, the hinges of the device can be quietly cut with a hacksaw.

Mortise locks

Installing this type of lock in a garage is quite problematic, and for thieves it is difficult to break into such a lock. big problems. The door is simply knocked down or opened with a selected master key. Experienced car enthusiasts recommend using this type of lock as an addition to the main bolt mechanism.

Pinwheel

Garage locks - turntables have simple design, but a fairly high degree of protection. The principle of operation of such a lock is that on the doors of the garage, made of wood or metal, lugs are made into which the ends of the lock - turntables - are lowered. The latch itself is mounted on a through bolt in the center of the gate and is activated by turning from the center. This type of do-it-yourself garage lock allows you to reliably protect your car from thieves, since there are no external (visible) parts.

The main positive feature of a screw lock is its design. The main part of the mechanism is hidden behind the door, making it virtually inaccessible to thieves. The common components of such a design will be: a key, a screw, an outer bracket and a bracket with internal thread. Make a castle if you have a detailed sketch and equipment ( welding machine And lathe) not difficult.

"Falling" model

If you have considerable experience in locksmith work, then try to make the so-called lock with a “falling key” yourself. You will need 3 metal plates. Two of them will be used for making staples, and the third will be used for a bolt (latch) with slots. The next step is to make a gear-shaped drum with a hole for the key. The key also has its own specifics. Special slots are made in it for a metal rod (pin) with protrusions, the arrangement of which follows the holes on the drum.

Electromechanical option

This type of lock is a combined one; it combines a mechanical and an electric lock. Please note that such locks can be made by craftsmen who have experience working with electronics and mechanics. If you are not confident in your abilities, car enthusiasts suggest using a ready-made mechanism and choosing the appropriate electric drive for it.

In order to make such a lock, you will need a gear mechanism, an electric motor, a power supply and a mechanism control system.
