Abstract:

A combination window shade and clutch assembly is provided to prevent over-tensioning of the spring motor of the window shade. The clutch assembly includes spool means connected to one end of the spring motor and cup means, both movable along the window shade dowel, and each having locking means formed to engage one another. The cup means engages retaining means formed in the rotatable housing of the window shade so that rotation of the housing is transmitted to the spool means through the cup means while their locking means are in engagement. The locking means of the cup means and spool means are operable to maintain engagement to permit tensioning of the spring motor a predetermined number of turns of the cup means and spool means together with window shade housing, and then disengage to prevent further tensioning of the spring motor without restricting rotation of the housing in such one direction.
