摘要： A shoot bolt mechanism comprises a casing (10) with the minimum distance between the front and rear edges. This is achieved by locating a handle-rotated boss (13) as close as possible to the rear wall and by providing a curved link (14) extending between a lug (31) on the boss and a shoot bolt (11). When the shoot bolt (11) is retracted, the link (14) lies around the surface of the boss (13) and in a recess (35) in the shoot bolt (11). The mecanism also includes two drive transfer members (12) which, as the shoot bolt (11) moves from a retracted to an extended position, move outwardly in respective opposite directions normal to the direction of the movement of the shoot bolt (11) to move respective shoot bolt rods (15). The mechanism can be used in moveable door and window frames to lock the moveable frame to the fixed frame at three spaced locations.
