How to install the door closer on the door - the rules and video

closers are designed for automatic soft-closing doors.Using a door closer is a prerequisite for installing the intercom and combination lock, moreover, closers are used in public institutions, on the front door entrances and gates in private households.

Types closers

prototype was the closer spring fixed at one end to a door or gate, and the second - on the door frame or pillar, near the hinges.Adjust this "closer" sometimes it was difficult, and the door is hard to open, but when you close clapped loudly.Modern closers are quiet and provide a smooth closing of the door without jerks.Structurally closers are distinguished by the installation location, the type of mechanism and mode of action.

Overhead closers mounted on top of the door or door frame, hidden - are inserted into the door leaf.There closers bottom installation, they are usually mounted on the glass doors of institutions.In this case, the mechanism is located at the door of the lower support.

most common and easy to install overhead top closers with guide rail or rack.They consist of silumin mechanism housing, and a lever rod with a sliding shoe or mounting rails.To adjust the force and speed of closing doors are provided adjusting screws.Complete with a door closer is often a mounting pattern on the scale of 1: 1, in which the layout can be done easily.Types of surface-mounted door closer discussed in this article.

modern internal latching mechanism consists of a spring working under compressive door is opened, and a gear rack or a cam mechanism.The closers, bundled with a code lock, usually use the first type of mechanism, wherein an increased effort in the final moment of closing the door, it's important to latch it closed.Cam mechanisms have a smooth closing, they are often used in rack closers.

methods and types of mounting

Closers overlay type can be installed both outside and inside the premises.When it comes to interior doors, choose a standard way of installation: door closer housing is attached to the side door opening, and bars with a shoe - on the door frame.

on the door leading to the street, it is better to establish closer on the inside, it will protect it from the harmful effects of moisture and dust.In addition, frost closer mounted side street can be frozen, and the door can not be closed at all.Therefore, choosing the interior installation whenever possible.In this case, installation of door closer is dependent on the design features and the direction of door opening.According to the rules of fire safety exterior doors should open outwards therefore have to strengthen the housing door closer on the door jamb or in parallel, to an additional mounting bracket.

installation technology latching

1. Select closer to the width and weight of the door, using the table of the European standard EN 1154. Thus, for door width up to 750 mm and a weight of 20 kg is enoughlatching class EN-1, parameters 850 mm and 40 kg - EN-2 and so on.device class specified in the documentation.At impossibility of matching the closer the desired class for the heavy door, you can install two units, evenly distributing the load
2. choose the place and type of door closer installation.This first estimate the direction of door opening.If the door opens "the" door closer housing is mounted on the upper part of the door leaf on the hinge side when "on my own" - the case is mounted on the door frame and door leaf is attached to the lever.Regardless of the type of traction - channel or lever - type closers Surface mounted on the same technology.

3. Apply a wiring diagram on the scale of 1: 1, attached to the groom at the same time to the door leaf and the jamb and cored through the paper mark a place of execution holes.The scheme is necessary to take the one that corresponds to the selected type of installation.
4. drilled holes required diameter into the door and the box.If the door is made of a thin metal or aluminum profile, you must use special fasteners - Bonk, do not allow metal to deform in a place of fastening elements.
5. Using screws secure the enclosure through a drilled hole and latching arm or shoe rack and pinions bar.By latching the body using the included screws attached mate lever arm is connected to the knee.

6. Adjust the knee lever so that it was set at 90 degrees to the plane of the door leaf in accordance with the picture.Figure "A" corresponds to the installation of the door closer to work "with latching action" mode, drawing "B" - without latching action.

7. proceeds to adjustment of the closing doors.To do this, open the door, closing speed and evaluated with the help of the adjustment screws bring it to the desired.
   

   Adjusting the closing speed of the door

8. When adjusting the latching mode with "latching action" to be installed on doors with latch or combination lock, you must explicitly adjust the speed and the door closing force in two areas: in the initial zone in the range of180 to 15 degrees and the lead 15 to 0gradusov.The speed and force of the end zone for a successful slam the door should be slightly larger, but the significant difference between the speeds to be avoided.
9. When adjusting it is important not to overdo it with a twisting screws, otherwise it may happen depressurization enclosure door closer with oil leakage, as a result of which it fails.
10. Some closers models have additional options, such as the opening of braking.When adjusting them as adjusted to the desired level.

Custom installation scheme

If it is impossible to establish closer the standard scheme resorted to installing additional mounting plates or brackets.Their design in each case it is necessary to develop the place, taking into account all the nuances.When a non-standard installation of the following options:

A. If it is impossible mounting arm to the door frame set mounting bracket, securing it with screws in a horizontal plane.The lever is attached to the inside corner.

B. The housing is mounted on the closer area, assigned to the upper slope of the door frame, and the arm is attached to the door.

B. At the door set the mounting plate that extends beyond the top edge of the web, it is attached to the closer body.The lever is attached in the usual way to the door frame.

harness G. The mounting plate is attached to the door frame, it sets itself closer, and the lever is attached to the door leaf.

D. Closer is attached to the door in a standard way, and the lever - to the mounting plate, increasing the area of ​​the door slope.

These methods allow secure mounting closer to the most non-standard doors and gates without reducing its functionality and reliability.

To extend the life of the door closer in operation is not recommended to make efforts for automatic closing doors, rush, or, conversely, to restrain the door.If necessary, lock the doors, for example, when you move, you must disconnect the lever of the door closer, but did not lock the door to different struts.Closer mounted outside doors should be protected from direct exposure to rain, protect from freezing oil.By following these simple rules door closer will serve faithfully for many years.
