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 window fastener having a mounting base (21), a latching flap (12) moveably coupled thereto, a handle (14) and a latching tongue (15). the handle (14) is movable between first and second positions and is coupled to the latching tongue (15) so that the latching tongue moves the latching flap (18) when the handle (14) moves to a latching position. A movement inducing mechanism (34, 41) operable by the handle (14) causes movement of the flap (12) to occur when the handle is moved from the latching position to a non-latching position.

Abstract: A locking device for a pair of telescoping tubular poles. An engagement member fits to one end of first pole and is slidingly engaged within second pole. A groove of the engagement member engages with a rib in the second pole so the first pole cannot rotate relative to the second pole. First pole also slidingly engages through a clamp which is mounted to the end of the second pole. A cover fits over the clamp. A cam located between the inside wall over engages with a clamping element of the clamp. A lever extends from cam through an opening in the cover. By manipulating the lever the cam can cause the clamping element to clampingly lock the first pole against sliding movement in the second pole.
