Abstract

An assembly for the transfer of operating movement around the corner of a window or door, particularly tilt/turn closures, involves an angled casing, guiding a flexible deflection member, which connects the operating rods of the closure. An intermediary connecting member between the flexible deflection member and an operating rod forms a slide bolt, preferably a tilt-lock locking-slide, which is stiffened by a longitudinal batten. The batten fits in a slot on one leg of the angled casing. The sliding bolt engages the flexible member by means of a cam-and-recess. The batten stabilizes the flexible member when it is under compression. The assembly and the sliding bolt are shaped to allow insertion in grooves in the profiles which form the closure frame. A clamping piece holds one of the legs in the frame. Elements of the assembly assist in dispersing transverse forces which can cause binding.

Dependent claims

Corner deflector assembly of a connecting rod type lock, insertable into undercut, profiled grooves of the frame profiles of windows and doors of metal, plastic, or the like, having an angled casing enclosing a deflection member of flexible bands, the angled casing having a first leg and a second leg, each of the legs of the angled casing guiding an intermediary connection member connected with the deflection member, in which the first leg has a smaller cross sectional height than the second leg, and in which the intermediary connecting member guided by this first leg serves at the same time as a sliding bolt and displays a cam which is guided in an elongated slot at the outside of the first leg, characterized by the fact that:

the elongated slot (23) guiding the cam (28) passes through the first leg (3) to the apex (27) of the angled casing and is opened at the outside of the second leg (4) and that the intermediary connecting member which forms a sliding bolt (29) engages in the elongated slot (23) of the first leg (3) by means of a longitudinal batten (33) molded onto the underside, said batten being carried through up to the free end of a bolt tongue (32).
