Lock for interior doors: how to choose a reliable and durable mechanism

Components have an impact on the functionality of the door. The locking device is the main element of the hardware, on which the safety of the structure depends, as well as the convenience of its use. To choose the most suitable lock for interior doors, it is necessary to study the main types of these mechanisms and their features.

The device and features of the locks on the interior door

When purchasing interior linen take into account the selection of fittings suitable for the particular case. To date, there are several options for locks, which differ in the method of installation and design features. The range of these products is very wide. Locks can be made of various materials that allows to expand their operational sphere.

The design of the lock for the door can also be different. If desired, you can choose the desired color of the product. In order to choose a locking mechanism, it is necessary to understand the principles of its operation. Locks consist of two main parts: the body and the cylinder. The body of the device contains a locking mechanism. The cylinder is the core of the castle, which determines the level of its secrecy. Depending on the purpose, all locking devices that can be purchased on the current market are divided into the following types:

  • without latch;
  • with latch;
  • with separate handle;
  • with pivot handle.

An interior door lock that does not have a latch can be equipped with a roller. In some models, this element is missing. Such products, as well as locking devices with a handle, which is located separately, are most often used in administrative buildings. This is due to the fact that they are more resistant to continuous use. The latter two types are used in private houses and apartments, where operating loads are lower.

Note! Cylinders of interior locks differ in their structure. They can be opened from one side or from two. All cylinders are classified according to proportionality. According to this indicator, they are divided into symmetric and asymmetric.

A variety of interior locking devices complicates their choice. In order not to be mistaken when buying a lock, it is necessary to study the main types of such products. Each version has its pros and cons, and also differs in operating recommendations. All interior locking devices can be divided into 5 groups:

  • latches;
  • with key;
  • mortise (with additional locking element);
  • magnetic;
  • smartlock.

The latter option is the most technologically advanced due to the fact that it has not only a mechanical, but also an electronic part. Such models are able to provide a high degree of protection of the door. Locks installed on interior canvases may have different costs depending on the complexity of the design, the manufacturer and the build quality.

The range of prices within which the implementation of interior locking devices occurs is quite wide. However, most often you can find products, the cost of which varies from 500 to 2000 rubles. This applies to absolutely all types of locks (with a latch, magnetic, etc.).

The resistance of the locks to cracking is determined by their design. When choosing a device, it is necessary to pay attention to the reliability class of the locking element. This indicator should be indicated in the relevant documentation, which is provided to the buyer when purchasing a lock.

Today on sale you can find locking mechanisms 4 classes of reliability. For interior canvases, it is recommended to purchase first-class devices, since such structures are often not used to protect the premises. The remaining 3 groups are applied on the entrance doors. If necessary, it will not be difficult without the key to open the interior door lock. As a rule, such mechanisms do not contain sekretki.

To date, this kind of locking devices is the most simple and affordable. Locks, equipped with latches, are installed on inexpensive doors. However, in some cases there may be exceptions. The mechanism of these models includes a cylinder and a tongue.

Locking devices of this type are used on doors that are mounted in a residential area. As a rule, they are installed in doorways leading to bedrooms, living rooms or kitchen rooms. Latches for interior doors have rather limited functionality. They prevent the door leaf from opening by holding it in the desired position.

Useful information! The simplicity of the design of such locking devices is an advantage of these products. This is due to the fact that when a mechanism is jammed, a similar door is much easier to open. More complex from a constructive point of view, in case of breakage, they require serious intervention in the mechanism.

The interroom door with the lock of this type without problems carries out the main functions. Of course, such mechanisms are not designed to protect the premises, as they lack a lock opening with a key. However, inside the premises of the canvas with such a device fit perfectly well.

The locks having a latch, in most cases are reported with the door handle. In order to remove the tongue from the mating hole on the barrel, it is necessary to press the handle. Latches for interior doors are very popular because they are easy to operate, and also have a democratic cost.

We should also mention the models that do not communicate with the door handle. The mechanism of such devices may include a tongue made not only of metal. For example, plastic parts are very popular. The use of locks that have a plastic locking element, it is recommended in the case when it is necessary to ensure the noiseless operation of the door leaf.

This kind of locking device is an advanced model of a simple lock, equipped with a latch. The difference in this case is that such a device includes not only the tongue, which is responsible for opening and closing the web, but also a special locking mechanism.

The main function of the lock is to hold the door in the closed position. Such models of locking devices are installed in the case when you want to ensure the possibility of complete closure of the door leaf from the inside. It should be noted that when jamming such a product it is quite difficult to disassemble. Door locks of interior doors, as a rule, are characterized by simplicity of design. In this case, the internal device is aimed at holding the web in the “closed” position.

Most often, mechanisms with a clamp are mounted on the doors to bathrooms and toilets. In addition, they can be found in the canvases, which are installed in office buildings – in offices and offices.

Open the interior door lock, which includes a locking mechanism, more difficult. Therefore, experts do not recommend buying cheap products. This increases the chance of acquiring low-quality products, which will fail at the first malfunction.

Note! Before you buy such a lock, you need to make sure that the tongue moves smoothly. And also you should pay attention to the features of the mechanism for returning the locking element to its original position.

Locks for interior doors with a handle and fasteners are designed with a wide plank, equipped with holes for fittings. In order to close the majority of models of such locks, it is enough to execute one turn of a clamp. The locking mechanism can be of two types: lever or push-button. The first option is the most common and requires turning the part responsible for the “closed” position. Products with lever lock, among other things, are more convenient to use as well as reliable.

Magnetic locking mechanisms are quite expensive. This is due to the fact that they are the most technologically advanced. These mechanisms are most convenient in operation. Their use ensures maximum noiseless operation, since the design of magnetic products does not contain moving parts that form friction.

Features of the device locks for interior doors with a magnetic lock determine their operational accessories. For example, these products are most often mounted on doors in children’s rooms where maximum silence is required. And also they are recommended to be established in sleeping rooms. Magnetic closures are simple and convenient to use.

Inside the devices that belong to this type of lock, there is a ferrite core. The operation of this element is possible only in one case – with a closed door arrangement. The core responds to a bar that has a negative charge and is in the correct position. When using a magnetic lock, the tongue does not look out from the end surface of the door leaf.

How to open the interior lock with a magnetic mechanism? The device closes is quite simple: to do this, you need to bring the locking element to the strike plate – and the mechanism will snap into place with a magnet. Opening such a door occurs by changing the location of the lever, which controls the tongue attached by means of a magnet to the counter opening.

Products that are of the electronic type are the most technologically advanced and expensive. It is worth noting that such locking mechanisms are called smart blocks. They include not only the mechanical part, but also the electronic part. The device of the lock of an interior door of this type is rather complicated when compared to other, less technological versions. Depending on the installation option, these products are divided into 2 types:

  • mortise;
  • outdoor.

Useful information! The principle of operation of electronic-mechanical locking devices, despite their complexity, is quite simple. The smartlock has an outer panel on which the numbers from 0 to 9 are located. Before use, the lock must be coded by setting it to recognize a certain combination of numbers.

In order to open the canvas, it is required not only to enter the necessary sequence of numbers, but also to turn the key. Such mechanisms are used in the case when it is required to ensure maximum security of the interior door. A door lock for a web located between rooms takes into account the blocking of a physical key in the event that the code was entered incorrectly.

It is important to remember that the electronic mechanism operates at the expense of a special battery, which is included in the design of the locking device. After it is discharged, the code plate is disconnected, after which it will be enough to use the usual key to open the door.

The most expensive models of such devices do not respond to a code number, but to a special magnetic card. Of course, the feasibility of installing such a lock is quite low, if we are talking about a normal interior door in a private house or apartment.

Depending on the location on the canvas, all locking devices are divided into 2 types: mortise and overhead. The most popular among the buyers are mortise devices that are mounted inside the door. These models include a secret key.

Mortise type resembles the design of the usual door locks, but it has a simpler device. In addition, such products are similar to the locking mechanisms, equipped with a lock. The difference lies in the fact that the hole located on the lock plate is intended for the key.

Useful information! It is recommended to do all the work consistently and carefully. In case of improper installation, you will have to disassemble the interior door lock. As a rule, re-installation only exacerbates the primary problems.

After organizing the markup, a niche is prepared for the mechanism. Next, you need to make holes for the handle and the locking elements. Then you need to install and secure the device inside the niche. At the end you will need to drill a hole for the tongue and set the strike plate for the lock. The interroom door with the locking device demands also installation of the handle. An important point is to check the operation of the installed mechanism.

Choosing a lock for interior canvass is a serious event. This requires taking into account many factors: the material of the door, its purpose, the type of locking device, as well as its decorative characteristics. Self-installation of door locks is made according to the instructions.
