ABSTRACT:
A motor and roller support includes a reversible lock clutch mechanism having a housing including an annular portion having a plurality of alternately deep and shallow recesses and a spindle axially received in the housing and having at least one flexible pawl positioned to cooperate with the plurality of recesses of the housing, with the pawl being unflexed when radially aligned with any of the deep recesses of the housing, and being angularly flexed upon being positioned in any of the shallow recesses of the housing. Upon alignment of the pawl with any of the deep recesses of the housing, relative rotation between the housing and the spindle can be initiated in either direction. However, upon the pawl being positioned with its end residing in a shallow recess of the housing and abutting the recess surface, relative rotation between the housing and the spindle can be initiated in only one direction therefrom. In the motor and roller support, the housing is adapted to engage a terminal portion of a roller and the spindle has means for engaging a supporting bracket extending from one end of the spindle outwardly of the housing, the means for engaging a motor, such as a spring motor. The motor and roller support is useful for supporting a strip, such as a window shade, a screen, and the like, secured to a roller for rolling and unrolling with respect to the roller.
