TILT LATCH FOR WINDOW

摘要

A sash latch for use in a sash of a window frame. The latch comprising a housing installed in the sash of the window frame, the housing containing a retractable slide, a pillar formed in the housing, and an extension at an end of the slide. The slide is movable to engage the extension with the window frame to prevent the sash from moving within the window frame. A slot is formed in a side of the slide wherein when a force is applied to the sash, the slide and the housing are deformed such that the pillar is received by the slot and prevents the slide from moving and disengaging the extension from the window frame.

an upper member with an upper surface, a planar surface with at least one arcuate edge and a lower surface; a spring cavity with a stop wall; a forward slot for engagement with an upper surface of a sash; an extension with a substantially planar surface and an inclined planar surface oppositely disposed from and at an acute angle to the substantially planar surface, the inclined planar surface being closer to the substantially planar surface at a first edge thereof than at a distal edge thereof; a notch-surface extending from the distal edge generally perpendicular to a substantially planar notch surface extending from the distal edge generally perpendicular to the substantially planar surface, a notch defined in part by the notch-surface, and wherein the notch opens in a direction extending generally perpendicularly away from the substantially planar surface, and the extension is retractably received into an opening in the side jamb of the window; a lower member, the lower member further includes an upper surface for slidable engagement with the lower surface of the upper member, a plunger arm extending outwardly from a support member, the plunger arm including an engagement nub at a distal end of the plunger arm; and a spring for receipt into the spring cavity of the upper member, the first end of the spring for contact with the stop wall of the upper member, the second end of the spring for engagement with the engagement nub of the plunger arm; wherein to retract the extension from the opening in the side jamb, the upper member is moved away from the side jamb causing the upper member to slide over the lower member and to retract the extension from the opening in the side jamb.
