| 摘要 |
A tilt latch and pivot housing is disclosed, which has a collapsible retainer on each of its side walls extending along a substantial portion of the length thereof and angularly outwardly from the side walls of the housing. The inner surface of each retainer is spaced from the surface of the adjacent wall of the housing, thus forming a crevice or gap designed to receive the retainer when sufficient pressure is applied to the retainer's outer surface causing the retainer to deflect inwardly. According to some embodiments, portions of the retainers adjacent to the upper engagement ends are beveled. The retainers may also be beveled on one end to facilitate installation of the housing into a sash. The housing of the present invention may also include a collapsible retainer formed at the bottom wall of the housing for preventing longitudinal movement of the housing after installation. Also disclosed are methods of manufacturing sash windows having tilt latches and/or pivots incorporating housings according to the present invention.
