1. A sliding door or window latch, including:
i. a strike including:
a) a latch engagement element;b) an anti-lift formation; andc) an anti-slam contact surface; ii. a latch body, including:
a) a latch housing;b) a latch member mounted in the latch housing, configured to move between: an unlatched position; and a latched position in which, in use, the latch member is positioned to engage with the latch engagement element;c) a protrusion that extends from the latch housing and is:
movable between a fully extended position and a partially extended position; andbiased to extend from the latch body to the fully extended position;d) an anti-slam mechanism actuated by the protrusion, wherein the anti-slam mechanism restricts motion of the latch member from the unlatched position when the protrusion is in the fully extended position but allows motion of the latch member from the unlatched position when the protrusion is in the partially extended position; wherein, when, in use, a sliding door or window to which the latch is mounted is moved to a closed position, the protrusion: contacts the anti-slam contact surface and is forced by relative movement of the strike and latch body to move from the fully extended position to the partially extended position, thereby actuating the anti-slam mechanism to allow movement of the latch member from the unlatched position; and engages with the anti-lift formation thereby preventing vertical movement of the latch body relative to the strike. |
