    摘要： The present invention provides a spring balance assembly for use with a sash window. The spring balance assembly comprises a plate, clip, pivot brake assembly, and first and second coil springs. The plate has a first portion, second portion, and a generally perpendicular transition portion thereby defining a cavity proximate the first portion. The cavity accommodates hardware mounted to the sash window during sliding movement of the sash window. The first coil spring is rotatably supported on a first spool and the second coil spring is rotatably supported on a second spool. A lower end of the first spring is connected to an attaching element of the clip. A lower end of the second spring is connected to a first wall of the pivot brake assembly and the clip is connected to the first wall to secure the first and second springs to the pivot brake assembly.

    摘要： 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.

    摘要： A sash lock for a sash window assembly is disclosed. The sash window assembly includes an upper sash window and a lower sash window. Each of the sash windows is mounted within opposed guide rails on a master frame. At least one of the sash windows is slidable within the frame relative to the other sash window. The sash lock comprises a keeper for mounting on a style of one of the sash windows. The keeper includes a keeper surface. The sash lock also includes a locking assembly for mounting on an adjacent style of the other of the sash windows. The locking assembly includes a housing having a hole, an actuator arm, and a cam having a cam surface for engaging the keeper surface. The locking assembly also includes a shaft extending through the housing hole and operably coupling the actuator arm to the cam. The keeper, the housing, the actuator arm and the shaft are formed of plastic and the cam is formed of metal.
