Features of door closers

The problem of the open doors can easily be solved by installing a closer, which controls the process of automatic opening and closing the door, closing it without additional power exposure from a person. The need for closers is dictated by quite practical and functional arguments. Suppose you put a massive front metal door. The door leaf has a large mass, and if you do not specifically hold the door when closing, the canvas will beat the lutka with great effort.

The door closers provide smooth closure of the door without unnecessary noise, set the speed of closing and opening the door in different areas, and also determine the efforts that a person should attach to open the door. The door closer is able to save heat or cool in the room in the room, as well as ensure the correct operation of the locking device. In addition, closers with the Hold Open function support the possibility of fixing the open door, which is very useful, since no items will have to be placed under the open door.

Dielings with the Dlavay Action mechanism allow you to leave the door open for a certain time, after which the door will close in ordinary mode. This type of device is considered convenient for doors in utility rooms (warehouses, auxiliary, pantries). This model is suitable so that you can open the door when carrying goods, then take the load, bring it into the building, and the door after this time itself begins to close, without requiring mechanical efforts.

The closers can be installed on ordinary interior and external heavy doors, taking into account the weight of the door and the width of the door leaf, and also not forgetting about the need to configure the door closer. The heavier your door, the more reliable and powerful the closer should be for her. The simplest version of the mechanism is the spring. But such a closer works too sharply and very noisy.

An ideal option is an adjustable design, which is also based on a spring, however, it is enclosed in a hermetic housing in the oil composition. The principle of operation of the door closer is quite simple. To open the door, a person puts a certain force, which is transmitted mechanically to the closer and accumulated by compressing the spring, which is built in the closer body. Then this spring returns to its original position, allowing you to adjust the process of closing the door.

Types of door closers

By design, door closers are divided into lever options, which are equipped with a crooked drive, and beverage models with a fist drive.

Inside the lever door closers is a spring and a hydraulic system, which is filled with oil. The hydraulic system performs the function of the shock absorber. When opening the door, the spring is compressed, and the liquid is pushed out of one to another container. After that, the spring straightens, and the oil returns to the first container. Although the hydraulic spring is located in a sealed box, sometimes it begins to leak, which is the first signal for the repair of the door closer.

The system contains valves that regulate the flow rate of fluid and the force in which it will move. They are responsible for the speed and smoothness of the door closing. The device of the door closer can be complicated by additional valves that provide different functions of the closer. For example, holding the door for a long time in an open state, or creating the function of a decklop to trigger a lock or better press the door to a lightning plate.

According to the installation method, the closers are divided into:

• closers for the surface installation, which are installed on top on the wall, door frame or door leaf, according to the door closer scheme;
• for a hidden installation that are attached inside the door; For flooring, when the closer is hidden to the floor.

If the tab does not fit into the design of the room, you can always install an invisible device that will hide in the indicated place and will be practically not noticeable. But for overhead models there are different decorating panels, or they can be painted in the selected color.

Methods for installing a closer on the door

Installation of the closer on the door does not need special training, because you can easily cope with this task. As a rule, all the necessary details and tools are included in the delivery kit. There are four methods of installation of the closer, consider them in more detail.

1. The easiest way to install the closer on the door is described to the instructions for him. It looks something like this: the lever shoulder is fixed on the device’s body, then using the template that is attached to the instructions, the screws are fixed, then the screws are screwed in this marking. The main thing that should be remembered that you will also need adjustment of the GEZE door leader.
2. The second method of installation of the door closer implies the following. It is necessary to attach the closer to the door so that its adjusting screws are turned to the door hinges. Next, it is necessary to fix the shoe of the device with screws, which are attached to the argument. Remember that the forearm of the device lever should have such a length that a right angle is relative to the door. The shoulder is attached to the shoe screws, after which again you have to think about how to adjust the door closer.
3. If you follow the third method of installing a door closer of a parallel lever, then you need to insert the device lever under the door bar, and then fold it outside the room. The closer in this case is attached with a bracket, which also comes with the delivery kit. When installing the closer, make sure that the adjusting screws rotate from the loops in the opposite direction. It is important not to confuse anything during the installation, otherwise the wrong installation will lead to the fact that you can’t do the optimal adjustment of the door closer.
4. There are closers who use the adjustable spring. It is easiest to install such devices: it is necessary to replace the loop rod and is ready. The main thing is that the product corresponds to exactly the weight of the door. If the door leaf is too heavy, and you could not find a suitable closer on sale, you need to install not one, but several closers.

DIY door leader repair

Proper operation of the closer, the key to his conscientious and long -term work that does not require repairs. In order for the door closer to work for a long time, you can’t pull or hold the door, thereby helping it close faster or slower. It is not recommended to fix the door, laying various items under it that prevent it from closing it, as well as to ride and hang or on the door (this applies to children).

To carry out the repair of the door closer, you need to have all the necessary tools at hand (hexagonal and wrenches, pliers and a set of screwdrivers). Before proceeding with the repair of the device, an external door examination should be performed, since its distortions or damage will interfere with the normal work of the closer.

Unfortunately, serious damage to the closer cannot be eliminated, since the tightness of the structure implies that it cannot be disassembled to separate parts and subsequently collected in accordance with the technology. Nevertheless, in some situations it is possible to repair the argument and commissioning his work on his own. Let's look at how to repair the door closer:

1. Flow of oil composition. Regardless of the fact that the hydraulic spring, which transfers the generated voltage to the levers, is in a solid sealed box filled with working fluid, its leaks still occur, most often in winter. If there is a leak, then this indicates the depressurization of the case and the appearance of damage, from which the oil flows out. As a result of this, the mechanism ceases to smoothly bring the door, loudly claps and turns into an ordinary spring. If you were able to find damaged areas in a timely manner, you need to seize them, which helps to extend the service period of the apparatus. However, if the damaged place is too large, it will not work to repair the door leader with your own hands and you will have to buy a new closer.
2. Damage to the lever unit. The most common is the violation of the integrity of the rods. However, this part of the mechanism is always visible, so its condition can be evaluated visually. Large force effects can disable it, causing breaks, bends, curvature or damage to fasteners. You can correct not very serious seizures of the bar with ordinary welding. If there was a breakdown of the fastener, it is possible to carry out repairs by buying new original parts that are suitable in size, fastener and shape of the landing part.

DIY door closer adjustment

Significant loads in the intensive operation of the door closer often provokes the discharge of the entire system. Therefore, it is recommended to carefully monitor and serve it several times a year, especially when changing the weather. But if the system nevertheless began to work with failures, then you should find out how the door closer is adjusted.

The argument adjustment procedure includes several points, the main of which is a change in the speed of movement. In the case of too slow opening the door leaf, it is necessary to adjust the compression level of the spring using the corresponding fixing nut. The speed of the door of the door is set by rotating the first valve (against and along the time).

You can twist the first valve for no more than 2 revolutions, which is specified by manufacturers of door closers. The second valve is responsible for the dohlop - the gap when the door is in a state of 10 15 degrees until the moment of closing. More expensive models also have a third valve in their design, which is necessary to adjust the door speed at an angle of 80-90 degrees.

If specialized oil is used in the closer case, then you can notice with the onset of winter that the argument speed falls in the cold season, and in the summer the mechanism is accelerated, on the contrary. This is explained by the fact that the viscosity of the fluid depends on the temperature. Therefore, with the onset of winter cold, it is necessary to additionally configure the door closer by regulating the first valve.

Often there is a need to delay the open door in this position for a while. An increase in the delay of the door leaf before closing can be achieved by a more tight tightening of a special latch. This manipulation is customary when the door is open by about 95 100 degrees. The open position of the door is also controlled using a certain option of the door closer.

If the door must be kept for a long time open to moving furniture or ventilating the room, then you should use the functions of the closer Hold-Open. Such a device is equipped with a lever to fix the door in the open position. You should open the door at 90-95 degrees and tighten the latch. After such manipulations, the door will be closed in ordinary mode, if you open it at a smaller angle than 90. If you open the door wider, it will be fixed and remain open until you pull on yourself, thereby removing the fixation.

In some cases, it may be necessary to change the angle of opening of the door. If necessary, you can change the angle of opening the door using a special valve, which should be turned behind or counterclockwise. The main thing when adjusting the closer is not to violate the functioning of the system: you can not scroll the screw more than 2 full turns, it is undesirable to tighten the screw to the stop, it is forbidden to completely unscrew the nuts and adjusting screws.

If you tried all the above tips on how to set the door closer, but nothing helped, then perhaps the whole problem lies in the wrong installation. Check the vertical installation of the door and the correct installation of the closer. Check the placement of the nut that regulates the force of the spring tension, remember that it should be located opposite the door loop. The lever should be so long that it is located at a right angle to the door box. In the presence of the slightest suspicion that you incorrectly installed the closer, it is recommended to remove it and put it according to all the rules.

Thus, without much expenses, having a screwdriver at the disposal and 5 minutes of free time, and knowing the methodology of how to adjust the door closer, you can independently configure this mechanism. The main thing is to remember some of the features of work that allow you not to violate the correct functioning of the system.
