Abstract: A window stop (10) for limiting movement of a sliding window along a predetermined path of window movement is provided. The window stop (10) has a housing (12) having a cavity (20) wherein the housing (12) is adapted to be positioned adjacent the path of window movement. A bolt (14), operatively associated with the cavity (20), is moveable between a first position (BP1) within the housing (12) and thereby out of the path of window movement, and a second position (BP2) extending out of the housing (12) into the path of the window movement whereby the window is able to contact the bolt (14).

Abstract: A sash balance brake and pivot pin assembly for a sash window that maintains the window substantially square prior to installation. The pivot pin extends outwardly from the window sash. The sash balance brake is disposed within a track in the window frame and includes a rotor rotatably disposed within an expandable housing. The pivot pin has a collar for lateral engagement with the rotor to prevent the window frame from bowing away from the window sash, thereby maintaining the window frame substantially square. The rotor has a first slot and a transversely disposed second slot defining an inner surface. The inner surface includes an angled surface to resist breakage of the rotor when the window sash in installed into the window frame. The rotor also has a pair of flats at a first end to further resist breakage of the rotor when the pivot pin is positioned at an angle with respect to the rotor.

Abstract: An economical, efficient window stop includes a narrow, flat housing having first and second cavities for respective flat, narrow bolt and latch. The bolt is spring braced and movable between a first portion within the cavity and a second position extending from the cavity. The latch is spring biased and moves transverse to the movement of the bolt. High strength molded plastic construction with guide means and close tolerances allow efficient distribution of forces from the extended bolt to the housing.
