Abstract: A latching mechanism which is primarily intended for use with hung and sliding window systems. The latching mechanism includes a body 10 and latch element 25, the latch element being moveable between a latching position and a non-latching position. The latch element 25 is coupled to a slider 36 which is moveable by an operating slide 13 mounted with lock furniture 11. The slide element 13 is coupled to the slider 36 by a lost motion member 34 which is operable to release a snap hook from engagement with the slider 36 prior to the slider 36 being moved from its latching position.

Abstract: A latch device intended for use with sliding and hung window systems. The latch device has a body (10) and a latch element (11) which is moveable between a latching position where it projects from the body (10) and a non-latching position where it is retracted into the body. A slide element (15) in a body (14) is coupled to a movable sub-housing (12) so that movement of the sub-housing (12) by the slide element (15) causes the latch element (11) to be moved. The body (10) is insertable into an opening in a window section and snap locks in place by the action of fingers (27) and face plate (18) acting on opposite sides of the window section adjacent the opening. The latch device can thus be fixed into a window section without any additional fasteners.

Abstract: A latch device for sliding and hung window systems. The latch device has a mounting base (15) with which a pair of counter-rotatable cam elements (11) are mounted. A lever cover (12) is slidingly mounted on the base (15). The lever cover (12) is coupled to the cam element (11) so that sliding movement of the lever cover (12) causes the cam elements to counter-rotate. Each cam element (11) has a cam portion (22) which is engageable through an opening (41) in a keeper (14) to latchingly engage behind a cam engagement surface (42) associated with the opening (41).

Abstract: A fastener for use with a sliding sash window. The fastener has a body (11) with a handle (14) mounted with the body for pivotal movement about a pivot axle (17). A latch tongue (18) is operatively coupled to the handle (14). A latch plate (21) has a latching surface (23) which is engageable in face to face contact with the end of the latch tongue (18). The latching surface (23) is spaced from the pivot axle (17) in the direction in which a sash (S) of a window is movable from a closed position relative to the frame (F) of the window. The handle (14) is movable about the pivot axle (17) to move the end of the latch tongue (18) away from its latching contact with the latching surface (23) of latch plate (21) to permit the window sash (S) to move from the closed position.
