Lock fitting for a swing window or door has a sliding rail structure riding in grooves at the swing and fixed frames moved by a drive and a sliding block to give a locking action in a number of window/door positions
The fitting for locking a window (1) or door has at least one rail (5-8) which, in the locked position, holds the swing frame (3) for the window (1) securely against the fixed window frame (2). The rail (5-8) moves in and out between the swing (3) and fixed (2) frames along a groove (11) in the fixed frame (2) and a counter groove (13) at the swing frame (3), on the plane of the frames across the longitudinal line of the rail. The rail is coupled to a drive (14) through a sliding block (20), which has a swing movement with the drive (14) and rail (5-8).
