Door Closer is a mechanism that provides smooth closing doors automatically.Correct installation and adjustment of the door closer on the door ensures the correct operation of the locking device and helps maintain optimum room temperature, keeping warm in winter and cool in the air conditioning in the summer heat.
the closer is the prototype of the modern common spring simply fixed to the door.Closing a door certainly accompanied by a strong cotton, it brings a certain inconvenience.
The basis of the closer and put a springplaced in a metal casing which is filled with a special oil.To slow and smooth closing doors have been implemented the principles of hydraulics: the transformation of the mechanical force applied at the time of opening, the slowdown in the subsequent closing of the door.
Closer working on the next, quite simple principle:
- at the time of opening the doors to a certain force is applied thereto;
- is a compression spring through the link arm, the piston and the closer the output shaft;
- liberated from the piston of the housing is filled with oil;
- at the time of closing the door spring is gradually expands, and oil flows into position.
door closer adjustment occurs by means of specially installed control valves which influence the closing speed.
main parameters of the choice of door closer ↑
Set closers available on conventional interior doors and external fence or gate.
When choosing a door closer in the first place should pay attention to the following parameters:
1. The weight and dimensions of the door leaf
main parameter of any door closer is its capacity or otherwise force the closing doors.Therefore, the wider the door leaf and the heavy door, the more power it should have.Sometimes, to increase efforts at large-fences should be installed just two closers.
Rationing efforts the closer is calculated based on the European standard EN 1154, defining closers seven different classes (EN1 - EN7).Following the recommendations of the standards closer class EN1 is intended for narrow and light door, and closer to the broad class EN7 and massive input barriers.When installed on a normal internal and external small door closers it is recommended to use 3-5 classes.
2. Ability to adjust the closer
The main adjustment parameters can be the closer note:
- force of closing;
- closing speed.
number of mechanisms for the additional tasks, equipped with a broad functionality:
- wind brake (Back Check), which protects the door from hitting the wall with a sharp opening or wind gusts.At the same time in some models has a function of setting the angle of operation;
- closing delay (Delay Action) will delay the closing of the door for a short period of time, which is very convenient for carrying small loads;
- function HOLD OPEN - is the ability to lock the door hard in the open position;
- stepless adjustment of the spring force.
3. Type the traction device
Depending on the installation conditions and the profile of the door closer design is completed with the following types of traction devices:
- standard traction device;
- device with a sliding arm;
- rod with a lock open position.
4. The method of mounting is
By way of mounting the following types of door closers:
- SMD, when the device is mounted directly on the door frame or canvas;
- for outdoor installation when installed closer to the floor and can simultaneously serve as support hinges for doors;
- with concealed door closer type of installation is placed inside the leaf.
5. Operating temperature range
Install door closer on the door requires a mandatory registration modalities and possible fluctuations in ambient temperature.Today went on sale a model with an interval from minus 35C to plus 70C.Also established closers, designed to work in very cold conditions - down to minus 45C.
6. The service life and protection against vandalism
Closers outer door must have high reliability and vandal-proof characteristics, and have a long service life.
parameters such as reliability and service life are based on the European standard EN 1154 and are dependent on a minimum number of cycles of opening-closing of doors without degradation of performance.According to the standard door closer must work at least 500 000 cycles.In addition, the housing outer coil units must be constructed of durable materials that are not subject to corrosion processes.
7. Design the closer
The exterior of the door closer is largely determined by its functional purpose.This tiny device can be made in any color, and a massive steel structure in white, dark brown and silver-gray design.
There are also a number of additional parameters that you should pay attention when choosing a door closer.This includes the frequency of operation of the door, set the quality of the door hinge and fasteners, the presence of electromechanical locks on the doors and external doors - the permanent presence of drafts.
How to install the device on the door with his hands ↑
Regardless of the type and characteristics of the door assembly to install the closer with your hands, you will need:
A. To install the door closer housing:
- assembly, corner and suspended platinum;
- plate for mounting.
B. For sliding channel:
- angle plate;
- mounting plate.
Before installing the door closer must pay attention to the parameters of the door opening.
It may be left-handed or right-opening doors as "myself" and "the."
When installing door closer on the outside door opening inside the enclosure must be placed on the door leaf, and the base of the lever on the door frame.
When the door opening "on my own" closer mounted on the door frame, and the base of the lever is mounted on the door leaf.
WARNING!It should not be used as a closer stop opening the door!It is recommended to use special door stops.You must also ensure that children are not riding on the self-closing doors.
Standard mounting accessories for smooth finishing ↑
The standard includes the closer:
- wiring diagram.
For convenience, the majority of manufacturers are making closers fixing scheme in full size.This allows you to use it for precision marking fastening door closer.
- selecting the optimum angle of the door opening in the description of the accompanying table, and using the scheme, it is necessary to partition the 4 holes for latching and 2 holes on the box door.
- Drill the marked holes.
- Next on the door jamb secure latching lever with screws.
- placing the main lever for square axis closers, secure it with the fixing screw.
- Carefully fix the door closer body.In this nut, which adjusts the spring force, must be positioned opposite the hinge.
- necessary to adjust the length of the variable lever so that it is positioned perpendicular to the door frame, and connect it with the main lever.
- Attach small decorative cap directly under the square axle housing closer.
- adjust all the required parameters of the door closer.
Adjusting door closers ↑
quality installation door closer - is the key to its effectiveness, so the adjustment of door closers must be done directly at the time of installation mechanism.Right-mounted door closer allows the door leaf to close smoothly and without jerks.
However, during operation there is need for further adjustment.For troubleshooting in the door closer is recommended to use the following tips:
- Too low or, conversely, too fast closing of doors is necessary to adjust the control valve closers.
- to increase or decrease the speed of "latching action" using the second adjustment valve.
- Adjusting the spring force and the opening angle of the door takes place by means of an adjusting nut.
- to maintain the door in the open position is sufficient to tighten the clamp.To unlock, simply close the door.
All adjustments are made in the course of, or anti-clockwise.The direction of movement will depend on the desired result.
WARNING!Door Closer To work effectively, it is prohibited to prop the door objects or hang heavy things on them.
Twice a year it is recommended to change the lubricant in the joints of the arms of the compounds.Also, every six months require adjustment of the door closer.
sliding door constructions can also be equipped with closers, which demonstrates the effect of the video clip.
