Abstract:
Locking balance shoes and balance systems to be incorporated in pivotable double hung windows include, in one embodiment, a pair of retractable tabs that partially extend through openings within an inverted window balance. In one embodiment of the method of installing such a system, an enlarged portion of the balance shoe is inserted into a window jamb and then rotated into position.
Abstract:
A snap lock balance shoe and system to be incorporated in pivotable double hung windows. In one embodiment, the snap lock balance shoe includes a pair of retractable tabs that partially extend through openings within an inverted window balance. Embodiments of methods for installing the system include inserting a frame of the balance shoe within a jamb track of the window jamb, rotating the frame 90 degrees about a first axis, and rotating the frame 90 degrees about a second axis such that the frame is substantially fully disposed within the jamb track.

Disclosed are apparatus for a block and tackle window balance to be incorporated in single and double hung window assemblies. In one embodiment the block and tackle window balance includes a roller secured within a bottom guide to increase range of travel of a window sash.
Abstract:
In a block and tackle window balance, the balance shoe holds and upwardly biases the terminal connector in a mounted position. A biasing element of the shoe maintains the terminal connector in a pocket of the shoe during operation of the balance. The terminal connector is prevented from laterally exiting the pocket in the mounted position by a widened portion on the terminal connector and a locating surface extending from the shoe toward the pocket. Manually pressing down on the biasing element or the terminal connector itself to lower the terminal connector in the pocket until the widened portion clears the locating surface allows lateral removal of the terminal connector from the pocket. During operation of the balance, however, the terminal connector does not experience a sufficient downward force to overcome the upward bias such that the widened portion never clears the locating surface.

Abstract:
An automatic closing device for returning a sliding section of a sliding door assembly to a closed position without application of an external force. The automatic closing device has a controlled return mechanism that has an adjustable mass assembly and a spring. The controlled return mechanism generates a force that returns the sliding section to its closed position after the sliding section is opened. The controlled return mechanism has a connector having a first end and a second end. The first end of the connector is attached to a fixed position on the sliding door assembly and the second end of the connector is attached to a top end of the controlled return mechanism. The controlled return mechanism has a pulley assembly having a plurality of pulleys that guides the connector from the top end of the controlled return mechanism to the fixed position on the sliding door assembly.
