Patent ID: 7191562

Claim:
A method for installing an inverted window balance system within a window jamb in a window frame comprising the steps of: providing an inverted window balance system comprising: a U-shaped channel with a plurality of openings; a spring connected to a system of pulleys located within the U-shaped channel; a cord with a first cord end and a second cord end, the first cord end connected and threaded through the system of pulleys, the second cord end connected to a jamb mounting attachment; and a balance shoe comprising: a frame comprising a frame bottom surface, a frame front surface and two frame edge surfaces; a locking member at least partially disposed within the frame; a cam in communication with the locking member; and a connecting device for attaching the balance shoe within the U-shaped channel; inserting the inverted window balance system within a jamb track of the window jamb such that an axis extending along a longitudinal direction of the U-shaped channel is perpendicular to a back wall of the jamb track and an axis that is perpendicular to the two frame edge surfaces is parallel to the back wall while the frame front surface faces a side wall of the jamb track; rotating the inverted window balance system within the jamb track 90 degrees about the axis extending along the longitudinal direction of the U-shaped channel such that the frame front surface faces down; and rotating the inverted window balance system 90 degrees about the axis that is perpendicular to the two frame edge surfaces such that the frame bottom surface faces in a downward direction.
