Locking locks appeared together with the construction of the dwellings and the emergence of property separation in society. As soon as private property arose, there was a need for its protection. Of course, there are still small settlements of people, where we are not talking about locking the doors, but it is rather an exception. For a large period, the blocking mechanisms were modified by the door frame, the manufacturers tried to make constipation more reliable, increasing its blocking properties. But the function of the lock apparatus was not changed - locking the doors and protection of property.

Structure of the mechanism of the castle

If you look at different photos door structures, then you can see that the constipation is installed not only on entrance doorsBut also interior structures are also locked.

Any fixture for locking consists of a locking mechanism, a metal special box for constipation, valves and an item for moving the riglel.

Depending on the device for locking, its functionality is determined. By the method of fastening to the door design, blocking mechanisms can be:

• overheads fixed on the inner side of the door;
• curl walls installed inside the door plate.

The most common device castle doors - mortise constipation, the organization of which is built from:

1. Hull;
2. Facial plank part;
3. Drive lever;
4. Casting with a special latch;
5. Casting with the main action.

Regardless of the attachment to the doors, the design of modern locking devices includes two components: a secret and actuator.

Using the Secretary System, the key is recognized to the lock, and the executive component locks out.

Types of secrets

1. Mechanical secrets are made in different versions, here are the most important of them:
2. Cylindrical. The basis of this option is a special detail - cylinder. It is in his core that elements that prevent the hacking of the castle are pins. The castle with this secret is called English and is the most common.
3. Suwald - consists of several teeth on the key that determine the number of Suwald.
4. Code - Opens the structure on the set of numbers during the key input.
5. Electronic - based on the drive that is embedded inside.

Types of performing devices

The following systems are used as the actuator:

1. Electromechanical - electric casuals.
2. Electromagnetic - magnet as a shut-off mechanism.
3. Mechanical - locking is carried out by a metal rod included in a special groove.

Organization of the castle of the Suwald version

The reliability of such a locking system depends on the number of plates than they will be more, the more effective there will be a protective function.

The Suwal type system consists of the following elements:

1. Transverse mechanism for grasov - reiguel;
2. Metal plate - Suwald;
3. Special turnkey opening.

The principle of operation of this system is to occupy all the plates of certain positions, after which it becomes possible to turn the key.

Structure of the cylinder lock system

Such a locking design may be mortise and invoiced, it represents a secret mechanism in the core - larva. Such locks of this type can be one-sided and bilateral. The first type can be opened with a key only on one side, the second contains two cylinders. It is impossible to open from the inside without a key.

Work on locking the premises with a cylindrical device is reduced to certain actions: the key is introduced into the groove with a limited protrusion, which is in the cylinder. Part of the cylinder is always rotating. But only if the key will be inserted. The rest of the design remains still - this is a housing. As an actuator, they serve pins that raise the key. Depending on the position of the pins, our constipation will be opened or closed. The opening of the mechanism occurs only with the coincidence of all encryption elements.

Interior door lock design system

In the interior version, the locking is not particularly in demand, but if such a design is required, the special castle built into the door canvas is selected, which consists of a swivel plate, shutter, springs, lever for retention, latch, housing cover.

Man leaving his apartment, got used to close it on a special mechanism - the castle. If before the lock systems were simple, today in the times of computer technologies, invisible locks appear, which can protect any apartment from hacking. Cheap locking mechanisms are easy to drill and knock out, and the locking system hidden in the canvas works only from the radio frequency of a special keychain. The locking design may have a challenging or simple system, but the experience suggests that it is better to choose one-quality constipation on the door panel than somewhat cheap and simple.

With the erection of housing and the appearance of stratification in the society on the property, there was a need to fix at home on the castles, to protect their private property. It is practically no left on the globe of places where people do not use it. For a long time, the device locking the door frame was modified. Manufacturers sought to make constipation reliable, improving its quality. However, the function of the door lock remained the same - it is locking the doors and preserve the htched things. Door constipation put on interior doors.

The main function of the door lock is locking the doors and protection of the house.

Types of door locks

All locking devices in their composition have:

• fixing device;
• special box for constipation made of metal;
• valve;
• the key to move the beelel.

From what is the design of the door lock, its purpose depends. The method of attaching blocking mechanisms to door device subdivishes them on:

• curling, they are installed inside;
• overhead are fixed on the inside of the doors.

It is necessary to remember, door invoices and mortise locks are manufactured for "left" and "right-wing" doors, do not advise when establishing them to turn over. This may contribute to their abnormal functioning.

Device cut-castle.

There are universal door locks in which the transition from the left to the right door is possible, and vice versa. This can be done if you rearrange the latch or latch. This operation is carried out without disassembly of the entire castle.

A curious type of overhead door lock is a lock-beam. He has two grains. They move across the entire width of the door horizontally. This castle arises to protect the door and from the side where the loops are located.

It is harder to install a mortise view of the door locks, hence the high probability is not particularly high-quality installation. The location of the door canvase, where their insertion occurs, is thoroughly weakened. And his closer location to external surface makes doors more affordable hacker. We must pay tribute to mortise locks that are less visible and more convenient to use.

Overhead door locks do not have such shortcomings as mortise. Install them elementary, in places of installation they do not lower the fortress. Overhead locks are perfectly functioning on the doors that open inside. This type of door lock perfectly protects against the attempts from the outside, but a hacker located in the room, it is not a hindrance. Overhead locks have a deficiency - this is a change external view Doors for the worse.

Scheme of the overhead door lock.

Door locks with multiple downes are manufactured now. They are called multi-surge castles. A reliable shut-off system of that deposits (riglels) of which is distributed across as much as possible the length of the door.

The most famous mechanism of the door lock is mortise constipation. It includes:

• housing;
• facial plank detail;
• drive lever;
• casov with basic action;
• casov with a special latch.

Regardless, what is the fastening to the doors, the adaptation of the current closing mechanisms contains two components:

• the secret, with his help finds the key to the castle;
• the actuator performs locking.

Varieties of secrets

Mechanical secrets are manufactured in various versions:

1. In the form of a cylinder. The basis is a special detail - the cylinder. In his middle there are pins - elements that interfere with the hacking of the castle. Such a castle is called English. He is most common.
2. Code. Opened when the key is introduced as a set of desired numbers.
3. Suwald. Finding multiple teeth on the key defining the number of Suwald.
4. Electronic. Created on a drive embedded inside.

Types of executive devices

Cylinder type lock: 1 - cylinder case, 2 - cylinder (core) with code mechanism, 3 - well for key, 4 - code pins (pins), 5 - locking pins (pins), 6 - leash / cam, 7 - Fastening hole, 8 - spring, 9 - key, 10 - separation line between the case and cylinder.

There are several systems that are used as an actuator. It:

• mechanical when the closure is performed by a metal rod, which is included in a special groove;
• electromechanical, here there are changes in electrical drive;
• electromagnetic, shut-off mechanism is a magnet.

The reliability of the locking system of the Suwald door lock depends on the number of plates. Their greater amount contributes to more reliable defense premises.

The system of this type of lock consists of the following elements:

• rigel, this is the transverse mechanism of gravity;
• suwald - metal plate;
• specially designed key for the key.

This system operates on the principle of classes by all plates of the established positions, only in this case can be done turning the key. Plates are placed under the influence of the keys in well-appointed positions. It permits to rotate the key and the mechanism of the door lock. But if at least one of the plates does not turn out to be in its intended groove, then all the device will not work. That is, the key is the lock code.

Such door locks are quite difficult to open the force of force. Suwald door locks have a long service life and a high degree of reliability. The advantages include their high secrecy and simplicity of design. Under all the rules of assembly and safety standards, such a castle is difficult to hack.

Structure of the cylinder lock system

Scheme of the Suwald Castle.

The cylinder locking mechanism is overhead and mortise. It has a secret device in the middle. Such door locks are manufactured:

• one-sided, they open the key only on the one hand;
• bilateral, these locks have two cylinders and on the inside are not open without a key.

In order to close the housing with such a lock, you need to perform certain actions: the key is inserted into the hole that has a limited protrusion. This hole is in the cylinder, the part of which is always spinning, but this will happen in the case when the proper key is inserted. The rest of the device will remain real estate - this is a housing. Executive adaptation are pins. They serve to raise the key. From what their position will depend on, constipation is open or closed.

The door lock will open only with full combination of all coded elements.

Interior door lock design system

Locking design scheme interior door With dimensions.

In some cases, it is required to close the door between the rooms, and then stop your choice on a special built-in door in the door. It includes:

• swivel plate;
• gate;
• spring;
• lever for hold;
• latch;
• case cover.

People over the years have developed a habit by leaving the house, close it on special door locks. Once they were very simple. Nowadays, the use of computer technology has led to the appearance of invisible locks. They perfectly cope with the task of ensuring the protection of housing from hacking. If the door locks are simple and inexpensive, then it is not possible to drill them and knock them out. The locking design hidden in the door acts solely from the radio frequencies of a special keyfob.

From this we can conclude that the best way out will purchase one high-quality constipation. You can connect in one locking system different types Door locks, it will complicate the work of hackers. It must be remembered that when choosing, you need to scrupulously examine such a design for all sorts of flaps so that it does not fail at the right moment.

From the quality of the lock largely depends on the degree of protection of any room, whether it is a commercial office or a shopping center or residential apartment and private cottage. The entire range of such mechanisms presented in the modern market can be defined in 2 major groups on the principle of installation - these are mortise and overhead door locks, the price of which is varied in a sufficiently large range.

Both options are equally in demand. Therefore, before you give preference to a particular design, be sure to get acquainted with all the advantages and disadvantages of each solution, functionality, as well as the installation scheme of the overhead and mortise lock. All the intricacies of the purchase and installation of the castles of the first type, you will learn from this article.

The invoice door lock is the most simple design. In the process of its installation, it is not required to cut part of the door canvase, which is one of the indisputable advantages of such a solution. It is installed directly over the sash - the main module on the canvas, the response part - on the box.

Important! You can open it outside the key, and from the inside - a special mechanism. Additionally, the configuration can go a variety of valves and wedge latches that block access to the room than the level of security is raised.

Device of an overhead castle

Standard equipment such a lock consists of:

Video about the action of the overhead castle

It is easy to understand the castle and the principle of its device in more detail how you can easily look at the video review below.

How to choose the correct overhead lock?

Before you choose a suitable mechanism for your room, view the possible options for models of the invoice lock in the photo. You can easily find them in the catalogs of specialized stores or in the Internet network.

When buying a door lock, consider the following criteria:

Installing an overhead castle

The circuit of the installation of the padlock is much simpler than the mounting of the mortise. The principle of action in this case is similar, but it does not require extra manipulations aimed at the exact cutting part of the door to embed the mechanism.

Installation Tools

Before starting work, be sure to prepare everything required toolsSo that the process does not slow down because of your forgetfulness. In this case, you will need:

Montage of the Patch Castle

In order to maximize the quick lock as quickly and correctly, it is initially carefully read the scheme proposed by the manufacturer of your selected model.

Then follow the following step by step instructions with basic recommendations:

Conclusion

As you have already been convinced, the principle of mounting the overhead lock is quite simple. If you clearly adhere to the setled rules, you can fulfill it without much effort, spending quite a bit of time. Be careful and careful when buying and installing the door lock, and it will surely serve you for more than a dozen years!

In order to protect your home and make the entry zone reliable, it should be well exploreddoor lock device, To understand what will be the most reliable and durable. Such a study will be useful inhabitants of the apartments of multi-storey houses, where often thefts are taking place with hacking and all because the locking agent was not reliable. Most likely, the owner of the apartment bought it at the lowest price in order to save money, but as a result, such savings leads to great losses.

Hope for the honesty of the seller in the store is also not necessary, as in order to sell a low-quality product, he is ready to paint in all colors so that the gulling buyer bought it. Therefore, it is recommended to understanddoor lock device, To find out what types it happens and how much he is resistant to hacking.

What types of locks are:

Locking devices, most often used to protect the entrance zone in an apartment or house, there are two types: mortise and overhead. The design of them and the principle of work is almost the same, but the installation is performed different ways. The first is cut into the door leaf and completely hidden inside it. It looks out for only the larva for the key. The second - superimposed on the canvas from the inside and fasten with nuts. They are completely visible, which worsens the aesthetic properties of the entrance zone, but for their installation, it is not necessary to disturb the integrity of the canvas, making the landing place. However, many prefer to make the cutting of such a device to hide it.

The device of overhead door locks:

Since this product is fastened outside, it must have a presentable look, which means that without the body it is not to do. Therefore, in its design there is a facial plank part and a drive lever that allows you to perform unlocking from the inside.

As for specifically locking devices, there may be two types of them: Casov with the main action and law with a special latch. Also in the design there is a closing mechanism, which usually includes two components, such as: secret and executive mechanism. Thanks to the first component, the key is recognized, and the second is targeted for locking. Hence,device of overhead door locks Not so complicated to not understand it.

Device of mortise locks:

As mentioned above, both species are the same in design and functionality, thereforedevice of mortise lockssimilar to the invoice, with the only difference that some details are missing, as they are superfluous. In particular, there is no need for a housing, since everything except the larvae and handle is hidden by the web. There is a small facial plank and drive lever that allows you to open a mechanism from the apartment. The rest of the design is repeated and includes:

• Casov with basic action or special latch.
• Secret.
• Actuating mechanism.

To repeat the functions of these parts again, since they are described in detail above. Thus, this type of protective means is also available for understanding.

Interroom lock device:

If we talk about the mechanical products of this kind, thendevice lock door, Installed in the doorway separating rooms, similarly to the described options. The installation feature is that the locking device is mounted by cutting into wood. Let us dwell on the interroom and consider all its components in more detail:

• Facial plank.
• Latch.
• Spring latch.
• Spring handle.
• Hole under the handle.
• Latch lever.
• Shoulder lever.
• Blocking system.
• Spring blocking system.
• Rigel.
• Secret.

As you can see Reminds other species and works on the same principle. The difference between the products used for the input zone and for interior use is quality. Everything is obvious, because no one will hack any doors inside the housing and therefore the strength of the closing products does not play a special role, as they perform the function of the most common basement. And heredevice lock door Entrance must have big reserve Strength and resistant against various bars and mechanical autopsy methods.

Device door knob and larvae

These two details must be present, since the handle is necessary for opening, and the key is inserted into the lark and scrolls. The latter can be replaced at any time to another, as it is a separate built-in product. Consists of the following details:

• Case.
• Core.
• Code pin.
• Closing pin.
• Check box.

Door lock larvae It becomes clear after studying the list of components from which it consists. To open or closing the system, you just need to insert the key and turn it. He, in turn, turn the checkbox that will activate the pins, put forward or rushing them.

Door handle device In general, the explanation is not subject to, since everything is clear. Pens can be of different shapes: from the traditional lever to a round model. On the other hand, they must have a quadruple, which is inserted into the seating hole provided for it.

Cylinder locks are classified at the installation site (overhead, mortise), also release one-sided (key-latch) and bilateral (key-key). In the first from the outside of the door, the lock opens with a key, and with the inner latch with swivel mechanism. The second type of devices opens / closes on both sides by the keys.

Consider the device of the cylinder mechanism

The cylinder mechanism is hidden in the metal case. Almost all such devices are produced by a single size corresponding to the EURODIN standard, it allows you to change the larva of the lock to any other if necessary.

The design of the device depends on the type of secrecy of the cylinder. Manufacturers produce mechanisms with different encoding elements. Technologies do not stand still, designers are working on an improvement, offering new patented technologies.

The most common pin cylinders, structures consist of:

· Corps;

· Cylinder rotor (rolling element called differently, eng. Plug);

· Code pins, (a set of secret parts interacting with key and locking);

· Distoping pins, blocking rotor;

· Cylinder cam;

· Spring mechanisms of counterparts returning them to places;

· Fastening hole.

How the cylinder works

The rotor is a key passage, the key is moving on it, which changes the position of the pins. These elements are built into the secret combination that coincides with the pattern on the key. Ultimately, the pins under the influence of the native key are installed in one line. The new position of these elements allows the rotor and the cam to be checked. When the key is removed from the key opening, the shut-off tests under the influence of the springs are pushing the code back into the rotary element, blocking occurs.

When a foreign key is taken, the code pattern of which does not coincide with the secret combination of the cylinder, the pins cannot be lined up into the correct position, alone will remain in the housing, others in the rotor. The rotor in this case will not be verified. The more difficult the combination, the more accurately all the elements are fitted, the harder it is to open the cylinder with a non-rig.

Vulnerable places in cylinders

If it is almost impossible to open the cylinder lock with a non-vandal key, then from the action of the vandals such devices are not protected, they can be drilled or knocked out. Protective elements help to resist, it is a bron alphabet made of particularly durable alloys. So that this item actually protects the larva from the vandal actions, it must be properly placed. It is installed inside the door of the door, and not on top of the metal or decorative sheat. The bron alphabet must be installed on all cylinder locks, and especially where the likelihood of their hacking by power methods is large.

What to do if the key was stolen or lost

Although the larva of the cylinder lock is easy to change in case of losing the keys, but it is not necessary to do this immediately. Many modern devices have a function of self-transcoding. What does it mean? The larva is sold complete with master key. When you lose the keys, you need to insert the master key and turn it out, transcoding will occur, and the old keys open the lock will be impossible. And you will need to make new duplicates from the master key. In the case when there is no transcoding function in the lock, it can be easily ordered in the service workshop, presenting the original key.
