Quite often, doors of various types equipdoor 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 closer. The more often the door opens, the earlier it will be necessary to perform this action. This is an easy process.
Adjustment of the door closer, the instruction for carrying out of which is discussed further, is quite feasible on its own. The device will be operated for a long time and efficiently.
Installing a door closer allows you to reduceload on hinges and fittings when opening and closing. The mechanism of this device is simple. Its versatility allows the use of a door closer on almost any type of door.
When opened, the force is transmitted through the thrust lever,piston on the spring. It is located in a chamber filled with oil or gas. At the time of opening the spring is compressed. At the same time, the contents of the camera flows into the vacated space. After easing 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.Passability of channels is controlled by screws. Thanks to them, the door closer is adjusted. The manufacturer's instructions indicate where these screws are located. Virtually all types of devices are easy to find.
There are several types of closers.They differ in their design and installation method. The simplest are considered overhead mechanisms, as well as devices that are installed in the door hinges (instead of content).
More complex closers are mounted whenarrangement of flooring. Their installation can be planned before starting repairs. Another type of mechanism are door closers hidden in a box or canvas. Instructions for their installation and operation requires a fairly large thickness of the entire system. Therefore, such a closer for interior doors is rarely used. More often this mechanism regulates the closure of input varieties.
If you want to install a door closer with your own hands, you should give preference to simple overhead models with a sliding rod. They are made on one pattern.
Choosing a door closer on a metal door,indoor or other types, should take into account a number of operating conditions. First of all, it is necessary to estimate the dimensions of the door leaf and its weight. Next is determined by the wind load during opening and closing. With the same web weight, a more powerful door closer will require a wide door.
To make it easier for the buyer to navigate inthe process of selecting the desired type of mechanism, has developed a classification EN1154. It includes 7 groups of devices. EN1 are designed for the lightest doors.
Also, when choosing to take into account the climatic conditions.Standard devices are operated in the temperature range from -35 to +70 ºС. If the winters are colder, you should take this into account and give preference to special mechanisms. The door closer, the characteristics of which are necessarily indicated by the manufacturer, can function even in severe frosts.
There are 3 main types of overhead designclosers. They may have a sliding, lever arm, as well as a clamp to stop the blade in one position. When choosing one or another variety, take into account the dimensions, weight of the door, the design of the building, as well as the operating conditions. An important role is played by the taste preferences of the user.
Sliding traction is characterized by hidden structural elements. Not every owner is satisfied with protruding lever mechanisms. Especially if you select a door closer for interior doors.
To install the door closer justifiedexpectations should pay particular attention to adjustment. Such devices most often have two or three settings. This allows the mechanism to work as closely as possible to the operating conditions of the door.
The first setting is carried out immediately after installation.door closer. In the process of opening and closing the door elements of the system will require additional configuration. Initially, you need to adjust the speed of closing the door. In the cold period this should happen quickly. Interior doors require slow smooth closing.
Then the power of dohlop is adjusted. It should be sufficient so that the door does not remain open. But strong dokhlop can quickly disable fittings and hinges.
If it takes some time to hold the dooropen or increase the intermediate closing time, you can use and configure additional latches. This allows you to increase comfort when using the door.
Adjust the door closer do it yourselfperformed clearly in accordance with the manufacturer's instructions. Usually the principle of setting for all simple mechanisms is identical. On the body of the door closer there are two screws. They can be promoted, but not very much. Having made two full turns, it is possible to expect depressurization of the chamber and breakage of the device. Repair it at home is impossible. Even a half turn of the screw significantly changes the speed of the door leaf. If you turn it counterclockwise, the sash will close slowly.
First, the door closing speed is checked.If it is large, the screw is turned half a turn. Next, you may need to add a little speed. To do this, turn the screw in the opposite direction by a quarter turn.
To adjust the dohlop on the last 15 cm toclosure speed set up the same way. To do this, unscrew the second screw. The procedure is similar to the previous action. Depending on the model of the closer you can pay attention to the angle of disclosure of the blade, as well as the average speed of the course.
A standard surface closure requiressettings during its operation. This is felt when the seasons change in oil models. The contents of the camera becomes thicker after the harsh winter frost. Therefore, the mechanism of the front door has to be adjusted more often.
To avoid frequent system setup andto purchase a durable device, it is necessary for external doors to acquire a special type of mechanisms. Inside they contain gas, not oil. This is a pneumatic door closer for access doors. Device adjustment is required less often. Gas does not change its properties during operation.
Additional functions of the closer denotespecific labeling. If they are not needed, it is better to buy a simple invoice closer for the door. The price of such a device will be lower. Additional features add value.
Today, the market for devices for smooth closingThe 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 quality closerfor the door, the price of which is 1000-1200 rubles. However, the cost of devices of foreign companies that are endowed with additional functions can reach 3,500-4,000 rubles.
Especially good in harsh winters showedmodels of the Finnish company Abloy and the Germanic GEZE and Dorma. Domestic closers are not inferior in quality to European models, and their cost is much lower. You should not buy cheap devices of unknown manufacturers that do not have the appropriate quality certificates. Such mechanisms quickly fail, reduce the service life of the door.
Devices of famous brands withstand from 0.5 to 1 million operating cycles. At the same time adjustment of the door closer will be required. The manufacturer's instructions accurately describe this process.
Сегодня лидеры рынка готовы предложить consumer various models of increased strength. They are often filled with gas, not oil. Such mechanisms are able to withstand not only adverse environmental conditions, but also improper operation.
If the closer is freely available, it must be equipped with a special valve. It will prevent the device from intentional hacking attempts.
But cheap overhead oil closers are extremelyneed to comply with the rules of operation. Such a mechanism does not allow to hold or pull the door during its closing. It is also not allowed its fixation (except for pneumatic models). Do not place foreign objects under the canvas. It is also strictly forbidden to hang or ride on the door. Therefore, if there are young children in the house, they need to be immediately explained to them.
So as not to have to change the device soontime, it is necessary to choose correctly and responsibly use the 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 instructions will allow it to be performed on almost every owner. This will give comfort when closing the door, as well as significantly increase its service life.
