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 move in opposite directions from a central lock body upon rotation of a handle. When the arms are in their mutually extended positions, a sliding detent locking member engages the upper shoot bolt arm to secure the window or door in the closed position. The central lock body includes a rotating driver for the shoot bolt arms 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.
