Abstract
An improved window sash lock keeper is provided having a slot to provide clearance for a burr, which is typically found on a surface upon which such a sash lock keeper is mounted. The improved keeper is typically mounted flush to a surface of an extruded window component. The clearance slot allows the keeper to be mounted with improved precision and thereby reduces interferences caused by misaligned window hardware.
Claims20
In combination a window sash lock keeper and window sash wherein said keeper comprises:
- a substantially planar back surface;
- and
- a slot extending at least partially across the substantially planar back surface wherein the slot provides a clearance for a possible burr or residual protrusion on the window sash.
A method of mounting a window sash lock keeper to an extruded window component having a burr or residual protrusion thereon comprising:
- providing a clearance slot in a back surface of said keeper wherein said clearance slot comprises a width and depth which are chosen to accept a typical burr or residual protrusion on a mounting surface of the extruded window component;
- aligning said keeper and said extruded window component so that said keeper is located to mate properly with a mating window sash lock, said burr or residual protrusion is accepted by said clearance slot and a back surface of said keeper abuts a mounting surface of said extruded window component;
- securing said keeper to said extruded window component by mechanical fasteners passing through mounting screw holes in said keeper and through said extruded window component.
In combination a window sash lock keeper and window sash wherein the keeper comprises:
- a front surface and a substantially planar back surface;
- and
- a slot extending at least partially across the back surface wherein the slot provides clearance for a possible burr or residual protrusion on the window sash, and wherein the slot is located and oriented relative to a mounting position of the keeper and the possible burr or residual protrusion so that the slot is capable of providing clearance for the possible burr or residual protrusion.
