    Abstract: 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.

    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: A sash lock (10) is provided for a sash window assembly (12). The sash window assembly includes an upper sash window (14) and a lower sash window (16). Each of the sash windows (14, 16) are mounted within opposed guide rails (20) on a master frame (22) wherein at least one of the sash windows is slidable within the frame (20) relative to the other sash window. The sash window assembly (12) further includes a keeper (26) for mounting on a rail of one of the sash windows. The keeper (26) includes a keeper surface (26a). The sash lock (10) includes a locking assembly (28) for mounting on an adjacent rail of the other of the sash windows. The locking assembly (28) includes a housing (30) having an aperture (32), an actuator arm (34) having a shaft (38) disposed along a rotational axis and within the aperture (32) of the housing (30), and a cam (36) having a cam surface (36a) for engaging the keeper surface (26a) of the keeper (26). The cam (36) also includes an engagement member (40, 52) to engage the shaft (38) of the actuator arm (34). The housing (30) of the locking assembly (28) includes two alignment tabs (33) that are each adapted to engage one of two alignment surfaces (26d) of the keeper (26).

    Abstract translation: 窗扇组件（12）设有窗框锁（10）。 窗扇组件包括上窗扇（14）和下窗扇（16）。 每个窗框（14,16）安装在主框架（22）上的相对的导轨（20）内，其中窗框窗口中的至少一个可相对于另一窗扇在框架（20）内滑动。 窗扇组件（12）还包括用于安装在窗框窗口中的一个的轨道上的保持器（26）。 保持器（26）包括保持器表面（26a）。 窗框锁（10）包括用于安装在另一个窗扇的相邻导轨上的锁定组件（28）。 锁定组件（28）包括具有孔（32）的壳体（30），具有沿着旋转轴线设置在壳体（30）的孔（32）内）的轴（38）的致动器臂（34） 和具有用于接合保持器（26）的保持器表面（26a）的凸轮表面（36a）的凸轮（36）。 凸轮（36）还包括与致动器臂（34）的轴（38）接合的接合构件（40,42）。 锁定组件（28）的壳体（30）包括两个对准翼片（33），每个对准翼片适于接合保持器（26）的两个对准表面（26d）中的一个。
