Balancing Arrangement For Double Hung Windows
US Patent:

Filed:
Dec 7, 1989
Appl. No.:
7/447533
Inventors:
James A. Leitzel - Elizabethville PA

Assignee:

International Classification:

Abstract:
A balancing arrangement for double hung windows is disclosed including a spring arrangement supported by a spring holder installed in a window jamb and a balance shoe installed in a window sash. The spring holder is adapted to engage a detent in the balance shoe installed in the top window sash, whereby displacement of the top sash when closed is prevented to maintain a weather stripping seal between the bottom and top sashes at the horizontal center of the window when the bottom sash is lowered for closing against the compression force of the seal. The opening of the top sash is unaffected, other than a slightly greater force being required to bypass the engagement of the detent by the spring holder.
