Door Closers: General Information

The closer - the universal mechanism intended for automatic, silent, smooth and reliable closing of a door. The principle of its operation is as follows: the mechanical force of opening the door is transmitted to the closer, which distributes the energy of this force to subsequent smooth, adjustable closing of the door.

Today, a door closer is something mundane, affordable and convenient. But it was not always like that!
  The first mention of closers, rather, however, for functionality, we will find in Antiquity. Even then, people tried to close the doors, resorting to rope and cargo.
In the 19th century, they tried to instill the role of closer in the spring of a pendulum door that opened in both directions. But closing such doors was more automatic than smooth and quiet, and the use of such doors was highly specialized.

The door closer, in the form in which we are accustomed to seeing it, came to us from the United States, thanks to the engineering thought of Mr. Blount. The mechanism he invented was mounted in the upper part of the door leaf, and its action was based on a crank mechanism and a piston. This closer had the ability to adjust the speed of closing the doors: with oil.

But, progress does not stand still! And now closers can have different types of drives that can be supplemented with hydraulic or electromagnet elements, install them in any convenient place of the door leaf.

Door closers: functions and types

The concept of a door closer is quite broad:
  - Car door closer, because there are doors in cars too.

-door door furniture used in the installation of sliding wardrobe doors, drawers, various kinds of swing doors in cabinets and lockers.

- door closers, just such a definition is used for closers used for automatic smooth closing of entrance and interior doors. And it is this type of door closer that we will consider in more detail.

Door Closers: How to Choose

To choose the right door closer for a particular door, you need to consider the following points:

  1. The width of the door leaf, up to 1.6 m: the wider the door, the more powerful the door closer should be, or the installation of 2 door closers at the same time is permissible.

  2. Mass of the door: the heavier the door, the greater the load on the closer. That is why for heavy, up to 300 kg, doors it is better to use floor closers, because due to deformation of the door and the door frame, malfunction of the door hinges under the heavy weight of the door itself, the upper door closers may not work correctly.

3. Type of door: for fire doors it is forbidden to use closers with mechanical locking, for all other types of doors - it all depends on the immediate desire of their owner and the functions performed by the door itself.

  If you take into account these main points, then the door with a door closer chosen by you will last a long time and without problems.
  In addition to all of the above, it is worth paying attention to the fact that door closers, the price of which is above average, are suitable for installation with door panels of a higher class: heavier, wider or specialized: fireproof, for example.
  The cost of a door closer depends on whether they have the ability to control the speed of closing the door, whether the function of fixing or cushioning the opening of doors is available to them. Door closers, adjustment of which is possible, are naturally more versatile, but their price is higher.

  Thus, it is quite simple to choose and buy a door closer. To do this, you need to know the parameters of the door on which you want to install the door closer and select the appropriate model for it.
