Tags:Hallway and corridor, With your own hands

None modern entrance doors do not do without closers. These mechanisms control the movement of doors and also protect fittings, locks and other elements from impact and damage. They allow the canvases to take a closed position. Manufacturers offer different door closers for entrance doors... The price of products depends on the type and specific technical characteristics. The choice of useful mechanisms allows you to install any structure - from light models to massive products.

The use of such mechanisms increases the comfort of using different door models

Door closer options for entrance doors

Such products are a type of fittings that are designed to optimize the movement of the canvas. It regulates the speed of opening and closing the door.

Closers are divided into the following groups:

upper devices;

floor or bottom appliances;

frame hidden mechanisms.

Overhead devices are considered a universal option. They are used for the entrance doors to the house.For simple installation of the door closer on the front door: the lever and sliding rod are mounted on the lintel of the box, and the body - on the inner surface of the door leaf.Mechanisms with a toothed gear and a lever drive are in demand. No less popular is a cam gear and sliding rod device.

Hidden models are mounted at the stage of installation of the entire structure. The lower units are floor mounted making them virtually invisible.

Helpful information! Modern model options allow you to independently adjust all existing functions.

The principle of operation and design features of the closer

The device contains a link arm and a housing with a mechanism that helps to assume the closed position.The main mechanism includes a spring that is compressed by the piston actuator.

Product device

A steel spring is embedded in the capsule. Smooth closing of the web is provided by a special technology. There is oil inside the capsule, which, when the element moves, enters the container through the hydraulic channels.

Door closers for entrance doors are adjusted using screws that are placed in the end of the case. The screws help to resize the channels, which affects the movement of the oil solution.

The nuances of adjusting the mechanism

In modern models, there is an additional valve that helps to hold the movement of the canvas. This design is effective in creating air resistance in the mechanism.

Some models are equipped with a motion blocking function. In this case, the spontaneous closing of the door leaf is regulated.

Modern floating draft models

Helpful information! Closers can perform additional functions. This is a delay in the door movement for a few seconds, dampers and coordination of door leaf closing.

How to choose closers for entrance doors

Before buying an entrance door closer, you should better study the main characteristics of the models:

moment of inertia, which is determined by the ratio of the quality of the springs, the dimensions of the products and the dimensions of the canvas;
the closing force is determined by the pressure that is exerted on the web during its movement. There are 7 classes of products, depending on the massiveness of the canvases;
closing speed;
slamming time;
closing delay is set individually;
fixing the canvas.

Some functions are configured during editing

The most important characteristic of devices is power. For street doors, stronger mechanisms are selected.

The table shows the classes of products depending on the size and weight.

Table 1. Classes of door closers depending on dimensions and weight

Closer class	Blade width (cm)	Product weight (kg)
EN1	75	20
EN2	85	40
EN3	95	60
EN4	110	80
EN5	125	100
EN6	140	120
EN7	160	160

The following types of products are distinguished:

in lever models, one edge is inserted into a special groove along which the lever moves when the door moves;
the knees are represented by two axes that bend when moving at the knee, which ensures a smooth ride;
gears are distinguished by the effect of the transmission of traction along the rack and pinion mechanism;
The cam mechanism is based on a profiled cam that transmits force to a spring.

For the closers to last a long time, the mechanism requires special care.

Note! If the door has a non-standard height, more than 2.5 meters, then it is worth choosing a device with a higher class.

Models and prices of door closers

When selecting products, the prices of door closers are important. Inexpensive upper products are produced by the Russian-Chinese company Apecs. The cost for them varies from 500 to 1500 rubles.Among the branded manufacturers are the German companies Gese and Dorma, as well as the Italian company Cisa

In the table you can see the prices for some products.

How to install door closers?

When choosing products, ease of installation and price are considered important parameters. Closers for entrance doors may differ in the installation method:

overheads are attached outside the canvas;

[caption id = "attachment_13944" align = "aligncenter" width = "700"]

hidden - built into the frame or floor;
frame are fixed to the box, and the lever is attached to the canvas;
floor-mounted are mounted from below and mounted on the floor.

Floor mechanism option

To perform a high-quality installation, you need to install the door leaf without distortions. It is not necessary to mount powerful structures on lightweight door options.Closers can be installed internally or externally. All models are supplied with instructions for correct product adjustment and installation diagram.The diagram is made in full size. It is attached to the surface of the canvas and the necessary holes are marked on it.

Stages of installation of the structure

After mounting the main mechanism, the link arm is attached. The length of the lever depends on the opening angle. If the installation has been done correctly, the door closes quietly and smoothly.A suitable opening angle is initially set. The screw selects the 180 or 90 degree position. Then the speed of movement of the web is set.If the installation is correct, adjustment will be required when the temperature changes.

Rules for using the device

During the operation of the mechanism it is not recommended:

make efforts to quickly close the door;
slow down or support the canvas;
swing on the door and pull the levers.

A good mechanism is distinguished by quality indicators and aesthetic appearance

If you do not follow the instructions for use, then this will lead to rapid wear of the oil seals, as well as damage to the gear or piston. If the structure breaks down, expensive repairs will be required or you will need to purchase a new device.

When choosing, you need to consider the need to use the open door mode. There is a special function for this.If it becomes necessary to keep the structure open, then a mechanism with a delay function can be installed. It helps to fix the canvas in the open position for a while.

Installing a modern door closer model will protect against the effect of "slamming doors". Correct installation of the mechanism will ensure a long service life.
