Door closer: functional features and advantages of application

The use of door closers to close the door allows you to ensure softness and smoothness in the implementation of this process. This element of the door accessories is widely used primarily due to the fact that it allows you to maintain the door in integrity and safety for many years of its operation.

Installation of standard closers located on top allows you to control access to the home, for example, in the entrances using the intercom system. In addition, the use of closers is widespread in offices, schools, hospitals, in places with a high operational load on the door.

If it is necessary to install a closer on a swing -type glass door, then it is mounted in its lower part. In addition, recently developed a hidden installation, which are installed inside the door leaf and perform the function of smooth closure of the door. Such images, the appearance of the door remains unchanged, and no one can damage the closer.

The use of closers for the door helps to protect heat in the room, especially in the cold season or in the summer, when working as an air conditioner. Due to the reliability of the design of modern argument models, they provide reliable door closing and differ in affordable cost. However, an incorrectly installed closer is able not only to break down soon, but will also lead to a door breakdown. Therefore, the issue of installation of door closers should be paid to special attention.

The principle of operation of the door closers is based on putting efforts to open the door, compressing a special spring, which in turn, gradually, pushes the door, closing it.

The main advantage of the installation of door closers is to ensure smooth closing of the door. Each of the models of door closers is characterized by the presence of special settings by which their work is regulated. The presence of a special hydraulic mechanism inside the closer allows us to ensure the fulfillment of the argument, the functions intended for him.

In the inside of the closer, there is a mechanism in the form of a piston located in the cylinder and special oil, thus, during its movement, the oil circulates through two compartments. Some manufacturers of closers replace oil with liquid stable in front of the frost.

In the process of changing the velocity of the oil, it is possible to adjust the speed with which the door will automatically close. Thus, due to the presence of a simple mechanism of work, the cost of closers is quite affordable, but functioning remains at the proper level.

Therefore, we highlight several functions of door closers:

• the ability of a two -band door tuning, the presence of acceleration when it is slammed;
• door protection from strikes;
• The ability to fix the door is open.

Door closer: characteristics and varieties

In relation to the location of the door closers, they are:

1. The upper type is the most popular and often installed option. The working part of the closer is located on top of the door. This version of the closer consists of a special system of levers, which, together with the spring, are able to close or fix the door.

In relation to the mechanism of action, closers are:

• with the presence of a toothy drive - in this device, a coat is directly related to the lever that ensure the operation of the entire system, such devices are characterized by the presence of a serrated pin or a tooth piston; Due to the presence of a simple design, closers have gained high popularity;
• closers with a sliding rod, as an axis, the presence of a cam heart shaft acts, with the help of which the spring and two pistons begin to act, two mechanisms - opening and closing actions are able to put a closer with bulky, but at the same time reliability, this version of the closers differs less popular than gear, although in terms of technical characteristics they are superior to them.

2. The floor version of the closers is an excellent solution for any door. They are functional and practical, in addition, do not spoil the appearance of the door. This version of the closers is found in large hypermarkets, shops, hospitals and other public places. Compared to the upper closers, this type of device do not have levers that move the door, door fixation is carried out on an axial element. Thus, a argument of this type is able to close the door, the total weight of which is more than 250 kg.

3. The hidden type of closer - are installed in the door, which requires an attractive appearance. Hidden closers are:

• with the presence of sliding rods - according to the principle of operation, they are similar to the upper closers of the same type, however, they differ in smaller sizes and hide in the door frame and canvas;
• Loaders of the loop are the most miniature devices, they are hidden in the door hinges, do not need to cut the closer into the doorbell, and therefore are very quickly installed, differ in certain shortcomings, namely, they are not suitable for massive doors, differ in a small working resource, and they are not suitable for all doorways canvases.

In addition, closers are classified in relation to the size and weight of the door that they are able to close. That is, if the weight of the door is up to 50 kg, then a simpler closer will be required than to work a door weighing about 100 kg.

Seven main classes of closers are distinguished, each of which is able to work on the door weighing: 20, 40, 60, 80, 100, 120, 160 kg. In addition, for each of the classes, there is a value of a canvas, which is the main guideline, when choosing a particular type of closer: 75, 85, 95, 110, 125, 140, 160 cm.

We do not recommend taking a closer to the forty kilogram door, on the door weighing 20 kg. Since, when opening such a door, you will need to strain hard.

DIY door closer installation

Installation of door closers is a rather complicated procedure that requires an attentive and serious approach to its conduct. If you lower errors in the process of its implementation, then the term of operation of the closer will decrease significantly. If the work is improperly performed, there is a risk of damage to door awnings, deformation of the door leaf.

Keep in mind that the installation of a floor and hidden closer is best entrusted to professionals, since this procedure needs certain skills in working with the door. To install the floor closer, you should calculate the door axis and the place of its closing. Installation of a hidden closer involves the marking of the place of cutting it on the door leaf, the installation of the recess in which it will be fixed.

To set the closer on the hinges, you should determine the angle under which the door will bend exactly to one degree. Since the upper closers are most popular, we suggest considering the instructions for their installation. The installation scheme of the top -type door closer, looks like this:

1. First of all, you should determine the type of door, the method of opening it. The top -type closer is suitable for any doors. For example, for the left -sided door, the opening of which is made in the inside of the room, involves the installation of the closer on the door leaf.

2. Before starting installation work, we recommend that you familiarize yourself with the instructions from the manufacturer, as a rule, each of the closers has it.

3. Next, the type of opening the door is determined, the installation diagram of the closer is applied to the canvas in order to understand how it should be mounted on the surface of the door.

4. Pay special attention to fasteners, since they have a fairly large load. Each time, in the process of opening the door, the fasteners lends itself to pressure. Therefore, if there are weak fasteners in configuration to the closer, they should be replaced with more durable.

5. If you plan to install closers on a plastic door, we recommend that you use screws, not self -tapping screws. In addition, a nut and washer is fixed at the end of the screw. Thus, the closer will serve longer, due to the fact that the mounts will be reliable.

6. After the installation of the closer is performed, the process of adjusting the door closer, which consists in setting up the screws, is most often two. One type helps to set up speed with which the door closes, and the second - the moment on which the door begins to close. The screwdriver, which screws the screws, allows you to adjust these indicators. If there is a function in the closer, which allows to fix the door in a certain direction, this parameter should also be adjusted.

Installation of the door closer and the rules for its operation

After the installation of door closers, they need periodic care, which will significantly increase their service life. If there are obstacles that do not allow the door to open, they are first removed, and then the closer is used. It is not recommended for a long period of time to leave the door on which the closer closer is located, as this contributes to the failure of the spring mechanism.

The closer installed on the front door needs periodic adjustment, at least twice in 12 months. Since in the winter and summer season, the viscosity of the liquid in which the piston is located changes, so it is recommended to carry out adjustment in the autumn-spring period.

If there are butterfly, the functions are not executed on the surface of the argument, the device should be replaced, since in most cases, the door closer does not lend itself to repair after a breakdown.

Features of the installation of a door closer

In order to install the closer case, the presence of:

• three plates of mounting, angular and suspended type;
• fixation plates.

To mount a sliding channel, you need to prepare:

• angular plate;
• Installation plate.

After buying a standard door closer, the door in its composition is present:

• the mechanism of the closer;
• fasteners;
• levers;
• Installation scheme.

In addition, in the diagram of the installation of closers, most often there is a sketch on the original scale, thus, a person who performs installation work has the opportunity to fit a closer on the door and determine the places where the holes for fasteners need to be drilled.

To carry out the installation of door closers for the doors, perform a number of actions:

1. Select the optimal value of the angle at which the door will open. According to the scheme, use the markings according to which four or two holes will be made for installation of the mechanism.

2. Make holes for the installation of the closer. Using screws, fix the closer on the door.

3. Using the mounting screw, fix the lever on the square axis of the closer.

4. Provide thoroughly fixing the body of the mechanism. Keep in mind that the location of the nut responsible for the settings of the spring mechanism should be the opposite door hinges.

5. The lever responsible for opening and closing the door should be adjusted in such a way that it is perpendicular to the door box and at the same time connects to the main purpose lever.

6. Close the surface of the closer with a small decorative cap. Adjust the argument parameters.

Properly configured door closers serve their owners longer, and at the same time provide smooth and uniform closure of the door. Although there are situations when during the operation of the door closer there are difficulties that require its adjustment:

• If the door opens too quickly or slowly, it is recommended to adjust the valve responsible for opening the door;

• The second valve on the closer is able to increase or decrease the speed with which the door slamms;
• The regulatory nuts can adjust the force with which the spring is pulled, and, accordingly, the angle under which the door closes;
• Tighten the lock allows you to hold the door open to remove the fixation, the door should be closed.

To adjust the closer, you should turn a certain screws against or by clockwise.

Tip: For the normal work of the closer, do not support the door with any heavy objects that prevent their locking and do not hang heavy objects on them.
