A mortise lock is installed directly into the door leaf and thanks to this it can be called the most durable and safe. Models with a rotary handle, as well as those that can be adjusted depending on the opening side, are popular. But, whichever locking mechanism you choose, be sure to check that the mechanism works clearly and smoothly.

Locks of various types are now produced color solutions, and they also differ in design and style, which allows you to choose a locking mechanism for any interior. Some of them are equipped with additional standard fittings. If you haven't found suitable option among those presented, it is possible to manufacture a locking mechanism according to individual project customer, which is quite convenient, since in lately Non-standard interior doors are often used in apartment interiors.

Magnetic

Magnetic based locks are the most modern version, the operating principle of which is based on the use of a magnet. When the door is closed, the magnetized part attracts metal part locking mechanism, which is the tongue.

There are several types of magnetic locks:

• Passive;
• Built-in;
• Electromagnetic, as shown in the photo.

Passive magnetic locks are more suitable for cabinets or accordion-style doors. They are easy to install:

• a metal plate is attached to the sash;
• and to the jamb - magnetic.

The door closes when the plates are connected, and opens when they are disconnected.

According to reviews, the electromagnetic lock is suitable for both interior and exterior doors, due to its ability to withstand pressure of 1 ton. It can even be used in garages and warehouses. The locking mechanism can be built-in or overhead, and it contains both mechanical and magnetic elements. It opens with a special key or chip that turns off the power. That's just for normal functioning This lock will require constant power supply.

Advantages

Why, when choosing a lock, is it advisable to opt for the magnetic option:

• Firstly, its operation is silent. Such a locking mechanism is perfect for a door to a children's room, as it will allow you to open and close it without fear of disturbing a sleeping child with extraneous sounds;
• The next advantage is ease of mounting. The lock can be recessed deep into the canvas, which is possible due to the extension of the magnetized part, and the location of the locking mechanism will not interfere with its operation;

• In such a mechanism there is no metal tongue, which is often the cause of wear on the jamb and the noise created. When closed, the entire mechanism is located inside, which ensures that no small objects get inside;
• Such a locking mechanism can be used without fear on the door leaf in the bathroom, since it closed design guarantees the absence of moisture inside it;
• The most important advantage of a magnetic product is its reliability. It will protect your door much more reliably than its mechanical counterpart.

Installation

If you decide to install a locking device yourself, then you must have at hand:

• drill;
• wood crown corresponding to the size of the mechanism being installed;
• hammer;
• screwdriver.

These tools will help in installing the old and installing the new product.

We make markings

The installation of the lock begins with markings. You should approach this process responsibly, since in many ways it affects the correctness of the entire further work and the final result:

• When marking, take into account the parameters of the hand, that is, the locking device and handle should be installed at a height convenient for you and your family members;
• The measurements should correspond to the arms being in the lowered position, as shown in the photo;
• Although you can follow the instructions or use in the usual way applications by attaching the lock and making the appropriate marks, as shown in the photo;
• The instructions describe the following parameters: you need to measure 4-5 cm from the end of the door and mark it at the location of subsequent installation.

Preparation

The next stage is preparing the excavations:

• Take a crown (feather) with a diameter of six and make a hole;
• Then you will need a crown with a diameter of two, with which you drill a small hole along the end and in the center of the resulting hole;
• After completing all drilling operations, try on the lock and make adjustments taking into account the lock fittings. At the same time, make sure that the connectors are larger than the mechanism or handle itself. Installation can be carried out on the prepared site.

Installation

It is not difficult to insert the mechanism, as they have special latches. The only thing worth remembering is that the clamping screws wear out quickly, so it is not recommended to use them twice.

You may encounter such a problem when the handle is installed incorrectly, that is, under a right-handed structure, when a handle is needed for a left-handed one. In this case, try rearranging the handle:

• to do this, remove the fixing spring;
• swap handles;
• and fasten the spring back.

2. False They are a handle with a latch. Having a simple mechanism, they provide fairly reliable operation. The castle includes the following elements:

- a tongue with an ending in the form of an oblique angle;

- cylinder.

The function of the lock is to hold the door in closed. Pressing the handle causes the tongue part to move under the influence of the spring, causing the door to open. The reed part is made of plastic or metal. Plastic carries out the work process silently, which makes it possible to use it in the production of roller and magnetic type locking products.

Advantages:

— a simple device allows you to carry out installation yourself;

— spontaneous opening of the door leaf is prevented;

— ease of use;

— large selection design;

- low breakdown rate.

Flaws:

— the simplicity of the mechanism does not allow the lock to be widely used.

3. Latches equipped with a lock(push-button or lever type). The latch limits the functionality of the handle on one side of the door leaf.

— latch (crossbar);

- strike plate;

— a case for a magnet;

- magnetic element.

The principle of operation is the attractiveness of the crossbar and the strike plate, which has a magnet. The strike plate is attached to the door frame. The lock itself can be overhead, mortise or semi-mortise.

Advantages:

— no noise during operation;

— reliability and durability of the mechanism;

— selecting the type of lock block.

Flaws:

— the dimensions of the lock case are far from compact;

6. Rim locks They are a rarity, but are still in demand due to their simplicity of design and easy installation. Modern models have a more compact body part. The lock block is installed on one side of the door. The reed mechanism is driven by rotating the locking part.

The purpose of the room places its own demands on the handle installed on the door. It should allow you to easily open the sash and securely fix it in the closed position. All that remains is to choose a suitable design. Locks for interior doors have different designs: they are represented by a wide range model range. To installed structure has served for a long time, you should select a suitable mechanism and install it correctly.

Magnetic

Despite the widespread use of mechanical products, magnetic products are also in steady consumer demand. They are a modern analogue of the previously described latch lock.

How to choose a lock?

When choosing a lock for interior doors, pay attention to the following points:

• Characteristics of the material that was used to make the door. Wooden sheet allows installation different designs. You will have to install more durable fittings on metal interior doors. Plastic sheets will require the installation of special components designed specifically for such products;
• Design features of doors. If any interior locks, then for sliding ones - only certain models;
• Purpose of the room. If you are buying a door lock for the bathroom, preference is given to a model that can be locked from the inside, and for an interior door leading to a children's room, it is better to choose a silent option;
• Geometric parameters of the canvas. The sizes of locks differ, and therefore for interior doors they are selected according to the width of the door leaf;
• Locking mechanism material. If indoors high humidity and installation is planned, it is recommended to give preference to products made of brass that are not afraid of corrosion;
• Manufacturer. It's better to choose proven ones trademarks. Well-known companies carefully follow manufacturing technology, choosing the most suitable for each element. suitable material. Certified products withstand harsh operating conditions;
• Opening method. If a handle with a lock is installed in a child's room, it should allow the mechanism to be quickly opened in case of accidental locking;
• Stylistic design of the room. A variety of colors allows you to choose the appropriate option among the available ones. If predominantly smooth lines are used in interior design, then when choosing a locking mechanism, give preference to a product with a round handle.

Choosing components from another manufacturer can create serious problems during installation and subsequent operation of the system. Here you need to know many subtleties that are inaccessible to a non-professional. If the door is double, then the problem is easier to solve. In this case, bolts are installed on one door at the bottom and top of the sash.

Installation features

After interior design will take its assigned place, proceed to install the selected locking mechanism. To do this, prepare equipment (drill) and tools (drills, angles, chisels, chisels). To understand the installation procedure for a specific mechanism, carefully study the attached instructions. It provides recommendations on the sequence of work and the fasteners that need to be used. The manufacturer, as a rule, also indicates the height at which a particular locking mechanism should be located. If there are no instructions, use general recommendations.

Execution order installation work looks like this:

• Marking seat. To do this, the lock is applied to the intended installation location in order to understand which option will do. Having decided on the installation location, apply a marking line;
• Holes are drilled and excess material is removed from the seat using a chisel;
• A hole is made to accommodate the locking structure;
• The handle is mounted. To do this, a fixing rod with a hexagonal or square cross-section is inserted into the prepared hole. The handle will fit onto the shaft on both sides;
• The performance of the system is monitored. If there are problems, the lock is disassembled and reassembled;
• The counterplate is installed. The length of the tongue can be measured with a ruler. It all depends on how far from the side of the canvas the box is located. After the location of the strip is precisely determined, the overlay is secured with self-tapping screws.
