Adjustment of door closer: instruction, device mechanism. Door closer installation

Quite often, doors of various types are equipped with a door closer. This small device adds comfort when closing. The door does not slam and does not remain ajar. However, over time, it may be necessary to adjust the door closer. The more you open the door, the sooner you need to perform this action. This is a simple process.

Adjustment door closer, the instruction of which is discussed below, is quite feasible on its own. The device will be operated for a long time and efficiently.

Principle of the door closer

Installing the door closer to the door allows you to reduce the load on the hinges and fittings when opening and closing. The mechanism of operation of this device is simple. Its versatility makes it possible to use door closer on doors of almost any type.

When opened, the force is transmitted through the traction lever, the piston to the spring. It is in a chamber filled with oil or gas. At the time of opening, the spring contracts. In this case, the contents of the camera flow into the space that has been freed up. After weakening the pressure on the system (at the time of closing) through the channels of the hydraulic or pneumatic system, the substance returns to the primary chamber.

This process is quite simple to adjust. The passage of channels is controlled by screws. Thanks to them, the door closer is adjusted. The manufacturer's instruction indicates where these screws are located. Virtually all types of devices find them simply.

Types of installation on the door

There are several types of closers. They differ in their design and method of installation. The simplest are overhead mechanisms, as well as devices that are installed in door hinges (instead of contents).

More complex closers are installed in the arrangement of flooring. Their installation can be planned before starting the repair. Another type of mechanism is concealed in the box or door leaf door closers. The instruction for their installation and operation requires a fairly large thickness of the entire system. Therefore, such a door closer for interior doors is rarely used. More often this mechanism regulates the closing of input varieties.

Wanting to install door closer to the door with your own hands, you should give preference to simple overhead models with sliding traction. They are executed on one template.

Important facts about the choice of the device

Choosing a door closer to the metal door, interior or other varieties, you must consider a number of operating conditions. First of all, it is necessary to estimate the dimensions of the door leaf and its weight. Further, the wind load is determined when opening and closing. With the same weight of the canvas, a more powerful door closer will require a wide door.

To make it easier for the buyer to orient in the process of selecting the right version of the mechanism, the classification EN1154 was developed. It includes 7 groups of devices. EN1 are designed for the lightest doors.

Also, when choosing, the climatic conditions are taken into account. Standard devices are operated in the temperature range from -35 to +70 ºС. If winters are colder, you should take this into account and give preference to special mechanisms. The door closer, the characteristics of which are specified by the manufacturer, can function even in severe frosts.

Thrust device

There are 3 basic types of construction of overhead closers. They can have a sliding, lever rod, as well as a lock to stop the blade in one position. When choosing a particular variety, take into account the dimensions, weight of the door, the building design, as well as the operating conditions. An important role is played by the taste preferences of the user.

Sliding traction is characterized by hidden construction elements. Not every owner is satisfied with sticking levers. Especially if you choose a door closer for interior doors.

Principle of adjustment

To install door closer to the door justified expectations, special attention should be given to adjustment. Such devices usually have two or three settings. This allows you to maximize the operation of the mechanism to the operating conditions of the door.

The first setting is done immediately after the door closer is installed. In the process of opening and closing the door, the elements of the system will require additional adjustment. Initially, it is necessary to adjust the speed of closing the door. In the cold period, this should happen quickly. Interior doors require slow smooth closing.

Then the force of the dohlop is adjusted. It should be sufficient to keep the door open. But a strong shutter can quickly disable hardware and hinges.

If you need some time to keep the door open or increase the time of intermediate closure, you can apply and configure additional locks. This allows you to increase comfort when using the door.

Adjustment instruction

Adjustment of the door closer by the hands is carried out clearly in accordance with the manufacturer's instructions. Usually the principle of adjustment for all simple mechanisms is identical. On the case of the door closer there are two screws. They can be untwisted, but not very much. Having made two full turns, it is possible to expect depressurization of the chamber and breakage of the device. It is impossible to repair it at home. Even half a turn of the screw significantly changes the speed of the door leaf. If it is turned counter-clockwise, the leaf will close slowly.

First, the door closing speed is checked. If it is large, turn the screw to the floor of a turn. Further, you may need to add some speed. To do this, turn the screw in the opposite direction for a quarter turn.

To adjust the shuttle on the last 15 cm before closing the speed is adjusted the same way. To do this, unscrew the second screw. The procedure is similar to the previous action. Depending on the model of the door closer, you can pay attention to the opening angle of the blade, as well as the average speed.

Expert advice

Standard door closer type of the overhead type requires adjustment during its operation. This is felt when changing the seasons in oil models. The contents of the chamber become more dense after severe winter frosts. Therefore, the mechanism of the entrance door has to be adjusted more often.

To avoid frequent system settings and purchase a durable device, it is worthwhile for the external doors to purchase a special type of mechanisms. Inside, they contain gas, not oil. This is a pneumatic door closer for access doors. Adjustment of the device is required less often. Gas does not change its properties during operation.

Additional functions of the door closer are indicated by a certain marking. If there is no need for them, it is better to buy a simple overhead door closer. The price of such a device will be lower. Additional functions increase the cost.

Models overview

Today, the market for devices for smooth closing of the door is represented by domestic and foreign closers. The most popular today are German (Dorma, Boda), Italian (Cobra, Cisa), Finnish (Abloy) devices. Domestic closers are represented by the company "Expostroymash Plus".

Today you can buy a high-quality door closer, the price of which is 1000-1200 rubles. However, the cost of devices of foreign companies, which are endowed with additional functions, can reach 3500-4000 rubles.

The models of the Finnish company Abloy and the German GEZE and Dorma proved especially good in severe winter conditions. Domestic closers are not inferior to European models, and their cost is much lower. It is not necessary to purchase cheap devices of unknown manufacturers that do not have the appropriate quality certificates. Such mechanisms quickly fail, reduce the life of the door.

Terms of use

Devices of well-known brands can withstand from 0.5 to 1 million operating cycles. This will require the adjustment of the door closer. The manufacturer's instructions accurately describe this process.

Today, market leaders are ready to offer the consumer various models of increased strength. They are most often filled with gas, not with oil. Such mechanisms can withstand not only unfavorable environmental conditions, but also improper operation.

If the door closer is freely accessible, it should be equipped with a special valve. It will prevent the device from deliberate attempts to crack.

But cheap overhead oil closers are in great need of compliance with the rules of operation. Such a mechanism does not allow you to hold or pull the door while it is closing. Also it is not allowed to fix it (except pneumatic models). Do not place objects under the sheet. Also, it is strictly forbidden to hang or ride on the door. Therefore, if there are small children in the house, they should immediately explain it.

In order not to have to change the device in the near future, it is necessary to choose the right and responsibly use the door closer. In this case, it will last a long time. From time to time, a simple adjustment of the door closer will be required. The manufacturer's instruction will allow it to be performed by almost every owner. This will give comfort when closing the door, and also significantly increase the service life.
