ABSTRACT:
A safety assembly for an actuating linkage of a metallic casement window or door includes an “L” shaped guiding body fastenable on the exterior of the movable frame of the window or door, a first and a second slidable member mounted slidably on the guiding body, a flexible element that interconnects the slidable members, and a safety block. A bolt is mounted in the block and is slidable transversely relative to the direction of motion of the first slidable member and against the action of a spring. The body has two transverse guides between which the safety block is inserted. The first member has two segments with different heights and the safety block has an opening oriented towards the body and directed in the longitudinal direction of the first slidable member to prevent motion of the safety block.
