Stay with friction grip for drop down flap of e.g. item of furniture

摘要

The drop support for a flap has two arms (1,2) linked by a friction joint comprising a coaxial construction and with the friction grip operating only in one direction ie. to provide a braking support when the flap is lowered. A friction ring (8) is fitted between a toothed ring (20) rotating about the joint and the first arm (1). The second arm has an outer cylindrical section set over the outside of the toothed ring. The shape of the grip teeth provides a friction grip in one direction only. The grip teeth profiles are parallel to the axis of the joint. The joint has a preset amount of angular movement.
