In most commercial buildings, houses and offices, you see door closers. These are mechanical devices that make a door close when people enter or leave. In this context, we shall focus upon the functioning of door closers.
Most areas that require door closers are fire doors. This helps in case of emergencies. Since all fire doors need to be remained closed, door closers help in this regard. They also help on a drastic scale in cases when fire may break out suddenly. If the fire doors are closed, the fire would not spread. Fire fighters too would be able to control the fire since door closers help in keeping the fire under in control.
Coming to the functioning of the door closers, we have two broad types; manual and automatic. Most common is the manual type used in offices. However, at some places where luxury is the key, automatic door closers are chosen.
There are two basic types of door-closers; manual and automatic. Both have different ways to function. Manual door-closers function by storing energy, which is used in the opening of the door by the compression or torsion spring, and releases the energy to close the door. Some manual door-closers allow the adjustment of the strength of the spring, making it easier or more difficult to push the door open.
Door closers are of different types as well. Some are manual while some are automatic. Manual ones are used widely in domestic areas while automatic ones are expansively used in commercial buildings and offices.
The manual door closers are known to be jamb mounted. They are referred to as overhead as well. The overhead style is quite common and widely used. This has a very typical box attached to the door frame as the jointed arm extends to the bolted in part. A jamb mounted gadget is usually installed in the inner side of the door, making it concealed. It is fitted towards the inner edge of the door and therefore, seems to be visible only when the door is left open as the stored energy needs to pull back the door with the help of the jointed arm. However, when closed, the device is not visible at all.
The closing speed of any door can be easily controlled with the help of door closers. Hydraulic dampers are quite common. Some areas make use of spring mechanism as well. This is done so by fitting in screws that can be adjusted so as to have the required speed of closing and latching.
This concludes the write up on the functioning of door closers. There are more intricate and complex mechanisms involved in the working of door closers, but the above mentioned functions are what a common man should know.
