Brake for sliding doors or windows - consits of a fulcrumed lever which locks in channel of support beam

摘要

A lever is attached to the leaf of a door or window and the base of the lever has a tongue which runs in a channel of the support assembly. When the tongue is in the stop position it grips the upper and lower inner faces of the channel. When the lever remote from the tongue is pressed the tongue ceases to grip the faces of the slot and the door or window is free to move on its rollers. When the lever is released the tongue grips the slot again, and the press. may be applied by an operator's foot.
