Who does not know any community or office (especially the public ones) in which the door, with automatic closing, gives a tremendous blow? And the portals “eternally open “? The one in charge of making the correct closing of any door are the so-called swinging door hinges, pieces usually placed on top of them, with a normally long aspect and with a “compass” type arm. How does a door spring or door closer spring work?
Swinging door hinges are based on two internal parts that act as a closure (the spring itself) and oil tanks in charge of braking. Through the regulation that all assemble (screw / s to vary its speed), a greater or lesser passage of the oil is allowed, achieving more or less speed when closing. The spring used is not appropriate for the door: It may be a spring too short in strength or of poor quality.
