Features of hidden door closers

Currently, fittings are produced by many companies, and therefore on sale you can find a large assortment of various devices that allow you to close the sashes and hold them in this position for the required time. A well-known example of a closer is a spring made of steel or rubber, which was used before the advent of modern devices. The main purpose of door closers is to close doors and keep them closed.

Today, door closer designs are more complex systems and allow the sash to be closed without noise and impact, which is important for designs that have glass inserts. And also some models can open doors at a certain angle and hold them in this position for the right time.

They are the most common and are used for interior partitions. They are installed by attaching to the door leaf and are often used in public buildings or offices where many people pass through the doors. The main purpose is to close the doors and hold them in this position. By their design features, these closers are:

• guides with a rod;
• with gear drive.

The differences between them are the mechanisms that are located inside the devices, which determines their principle of action. Models with a gear mechanism transmit motion using gears that move along a pin. Typically, such devices are used for heavy structures.

These devices are distinguished by a hidden installation method, and with their help you can open doors in different directions. They are often installed on glass doors in sales areas. Such devices can support a lot of weight.

Such devices are used for interior doors, and they are called frame. A design feature of such a device is a mechanism that slides inside the case. The advantages of this model are small dimensions, which makes it possible to cut them directly into the canvas and maintain the integral appearance of the door.

These devices have appeared quite recently, but they are already popular among users and are distinguished by great functionality. It is difficult to distinguish them, at first glance, from ordinary hinges, and at the same time it is not required to install additional structures on the door leaf during installation. These mechanisms differ from standard hinges in slightly larger sizes.

But they also have some disadvantages. Among them are:

• weak effort;
• installation complexity;
• inability to withstand heavy weight;
• short period of validity.

Such devices are most often used for installation on interior structures with low weight.

Usually they are used in the manufacture of furniture, the main purpose is to reduce the force of impact when closing the doors. The design of such products is quite simple, and they themselves are small in size. There is a spring mechanism inside the body.

Such devices can be installed before installing the door itself or after installing it. Everyone should choose the method that is more convenient for him to produce.

For work you will need:

• cutter;
• drill;
• screwdriver;
• hammer.

When carrying out work, some difficulties may also arise with determining the right place for attaching the mechanism. When inserting, all the work must be done correctly and the mechanisms must be tightly fastened in order to prevent mistakes, otherwise the closer will work poorly. Closers are often placed at the end of the curtain, which ensures ease of use. If necessary, you can quickly remove the structure from the hinges, freeing the doorway. Such a closer will not be visible to strangers, and it can be quickly replaced.

To install the device, you must adhere to clear recommendations from specialists and observe the following rules:

• check the kit for the presence of the necessary elements and parts, among which there should be fasteners, levers, mechanisms and installation diagram;
• use the scheme to determine the order of work;
• correctly assemble the mechanism and mount it in the right place;
• adjust the traction.

After installation, it is necessary to carry out work on setting up the closer. It is also important to check how the door will close or open. The blade should move slowly and quietly. If such moments are not observed, then it is necessary to make an adjustment first. The process is quite simple, and its basis is tightening or unscrewing the bolts that weaken the action of the spring or hydraulics.

To carry out the work, it is necessary to remove the door closer cover, where the adjustment bolts are located. Next, you need to decide which bolt is designed to move the mechanism in one direction or another, and twist it, periodically checking the door's performance. The bolts must be pumped one at a time.

In this case, the adjustment is carried out by turning the bolts 1-2 turns. To avoid the need to carry out such events often, it is recommended to use those devices that are undemanding to temperature indicators, for example, with spring mechanisms, and also to maintain the temperature in the room that is optimal for the operation of mechanisms.

When buying such a device, one must take into account the mass and width of the door leaf. Dorma products usually work according to the EN 1154 standard. If a model is chosen incorrectly, it will soon fail or will not function correctly. This will bring some difficulty in opening and closing doors.

Each door closer is divided into gradations and is designed for a particular weight and door width. All these points must match the parameters of the canvas.

For exterior doors, it is recommended to purchase special models that are not afraid of frost and heat, and also have a special design and are filled with frost-resistant oil. Such a device usually comes with all the necessary materials and elements, which allows you to install the device on any door, regardless of the material of its manufacture.
