Lock fitting for sliding door, window or similar

摘要

The locking fitting (1) has a casing (3) with a slide (4) inside the casing for longitudinal movement. The slide has a projection (11) on its face (10) adjacent to the external wall of the casing. The projection, in the locking position, extends for a predetermined height (c) so that it projects through a longitudinal opening (8) in the wall of the casing and engages against an edge (12) of the exterior wall defining the longitudinal end of the opening at the side opposed to the locking direction. Return springs (14) bias the slide towards the exterior wall of the casing to allow lateral movement of the slide at least equal to the projection extension height.
