Abstract

A centrally located window release retractor handle for a tilt-in window is presented. The handle readily attaches to an existing tilt-in window top sash. Attached to the handle is a retractor wheel. Attached to the retractor wheel are left and right retractor cables which are in turn attached to the left and right window release retractors. As the handle and wheel are rotated, the retractor cables are tensioned and draw the window release retractors inwardly. This action allows the tilt-in window to release at the top. The window may then be tilted inwardly by use of the handle leaving the user's other hand free to clean the window. The device is suitable to be mounted on the top of existing tilt-in windows although it may also be manufactured as a complete unit with the handle and retractor cables completely inside the top sash.

Dependent claims

A retractor mechanism for a pair of tilt-in window release retractors wherein said retractors are spring-biased outwardly, for a window slidably located within a frame having a cross-bar, said window having a top sash with left, center and right portions, comprising:

(a) a rotatable handle having a retractor wheel attached thereto, said handle located near the center of the top sash;
(b) left and right flexible retractor cables, each cable having one end attached to said retractor wheel and the other end attached to a spring-biased window release retractor;
whereby, rotation of said handle by 180 degrees pulls said window release retractors inwardly thereby releasing the top sash of said window from said frame, wherein said rotatable handle further comprises a locking part attached thereto, further comprising a handle locking bracket on said cross bar adapted to receive said locking part when said rotatable handle is rotated 90 degrees, whereby said mechanism locks said window to said cross bar but does not release said release retractors when said handle is rotated 90 degrees.
