Abstract (en)
[origin: ES8407453A1] A plate is attached to a rail which moves vertically in a housing. The housing includes a brake which rubs on one side of the rail on the other side, there is a roller. A leaf spring is positioned between the housing and the roller. When the rail moves vertically in one direction, the roller is pushed progressively harder against the rail. This squeezes the rail against the brake, creating a braking force on the rail that increases, to maximum, in relation to distance the rail moves. This arrangement may be used as a buffer for an elevator cab or counterweight in an elevator.
