Two point lock for bi-fold windows and doors
A two point lock for securing bi-folding windows and doors in which upper and lower shoot bolt arms (32, 34) move in opposite directions from a central lock body (30) upon rotation of a handle (14). When the arms are in their mutually extended positions, a sliding detent locking member (50) engages the upper shoot bolt arm (32) to secure the window or door in the closed position. The central lock body (30) includes a rotating driver (40) for the shoot bolt arms (32, 34) that is supported at both ends and is maintained in two different positions by interaction with the curved contact faces of a set of biasing pads (70).
