Features of hidden door closers

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

Kinds

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

When choosing these devices, it is necessary to take into account the device of the products.

Overhead

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 a lot of people pass through the doors. The main purpose is to close the doors and hold them in that position. According to their design features, these closers are:

• rod guides;
• with gear drive.

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

Products with a sliding rod can transmit forces from the door leaf to the spring with the help of thrust. All these elements are located in one housing, which is filled with oil. This makes it possible to adjust the course of the door. The installation of these devices is carried out taking into account the direction of movement of the doors.

floor standing

These devices are distinguished by a hidden installation method, and with their help you can open doors in different directions. Often they are installed on glass doors in trading floors. Such devices can withstand a lot of weight.

A feature is the design of such devices - this is a rod located vertically, on which there are springs. When opening the doors, it winds the spring, and then returns to the opposite position. The mechanism is attached to the doors with screws.

Hidden

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 embed them directly into the leaf and maintain a holistic appearance of the door.

Closer hinges

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

But they also have some disadvantages. Among them are:

• weak effort;
• installation difficulties;
• inability to withstand heavy weight;
• short term.

Most often, such devices are used for installation on interior structures with low weight.

Closers for sliding structures

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

The disadvantage of such devices is that they have pins protruding from the body, which can be damaged, and therefore they are often placed in inaccessible places.

Installation and technological features

Such devices can be installed before the installation of the door itself or after its installation. Everyone should choose the method that will be more convenient for him to produce.

For work you will need:

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

During the work, there may also be some difficulties in determining the desired location for attaching the mechanism. When inserting, it is necessary to correctly carry out all the work and tightly fix the mechanisms in order to prevent mistakes, otherwise the closer will not work well. Closers are often placed at the end of the canvas, which ensures ease of use. If necessary, you can quickly remove the structure from the hinges, freeing the doorway. Such a door closer will not be visible to outsiders, and it can be quickly replaced.

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

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

Adjustment process

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 canvas should move slowly and silently. If such moments are not observed, then it is necessary to pre-adjust. The process is quite simple, and its basis is to tighten or unscrew the bolts that weaken the action of the spring or hydraulics.

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

But it is also important to consider that the built-in closer may work differently depending on the temperature in the room. If the room is very cold or overheated, then settings are made under each of the temperature modes.

In this case, the adjustment is carried out by turning the bolts 1-2 turns. To avoid the need for frequent such events, 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 the mechanisms.

How to choose?

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

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

It is worth choosing ball systems according to optimal indicators. It is also supposed to be possible to install closers with higher characteristics, which will extend their service life.

For external 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.
