Abstract
A mechanism is provided for balancing and positioning a sash of a self-balancing double-hung window assembly. The mechanism may include a fixed length cable, a pulley, first and second brackets and an adjustment member. The fixed length cable may include first and second ends. The pulley may support the cable. The first bracket may include one or more attachment points relative to the first end of the cable and may include an upper end and a lower end. The second bracket may be movable relative to the first bracket and may be configured to support the sash. The adjustment member may engage and extend through the lower end of the first bracket and may be movable relative to the first bracket to cause corresponding movement of the second bracket relative to the first end of the cable.

A self-balanced double-hung window assembly comprising:
- a window frame including a dividing member defining a first jamb channel and a second jamb channel;
- a first sash movable within the first jamb channel;
- a second sash movable within the second jamb channel;
- a cable having a first end supporting the first sash and a second end supporting the second sash;
- a pulley supporting the cable;
- and
- a housing at least partially disposed within the first and second jamb channels and supporting the pulley for rotation relative to the housing such that rotation of the pulley in a first rotational direction causes corresponding movement of the first sash in a first linear direction and corresponding movement of the second sash in a second linear direction, the housing including a body portion and a rib member extending outward from the body portion in a direction substantially parallel to an axis of rotation of the pulley, the rib member cooperating with the dividing member to form a substantially continuous jamb wall separating the first and second jamb channels;
- wherein the second bracket includes first and second members, the first member being configured to support one of the first and second sashes, the second member being fixed relative to the first member;
- and
- wherein the second member slidably engages the first bracket.
