ABSTRACT:
A latch fastener for construction elements such as windows, doors or the like which includes a base member and a movable member having a latching hook configured to cooperate with a fixedly secured striker plate for selectively locking and unlocking the window or door. The members have positioned therebetween, several bearing balls which facilitate movement of the movable member and latching hook relative to the base member between at least two positions corresponding to the locked and unlocked positions of the window or door. The base member and movable member include correspondingly oppositely positioned tracks which define races for the bearing balls and which permit rolling movement of the bearing balls when the movable member is moved relative to said base member. A resilient spring retains the movable member and latching hook in a normal position corresponding to a locked position of the window or door as the case may. The latch fastener provides unique continuous and smooth operation which facilitates positive locking of the door or window and avoids the wear and deformation on the components normally caused by shock forces to which they are subjected when the door or window is closed. This advantage is provided by the translation of such shock forces from their initial direction which promotes friction to a direction perpendicular thereto.
