ABSTRACT:
A clutch brake assembly which may be used for roll up awnings and the like which will allow the roller on which the awning is rolled to freely rotate in one direction and be locked against rotation in the other direction, the directions of freewheeling rotation and locking being selectable by manual rotation of the cover between either of two toggle positions. The assembly includes a nonrotatable shaft extending through the assembly and fastened by arms to the side of a recreational vehicle or the like. Mounted on the shaft is a rotatable drum on which the awning is to be rolled and unrolled, that drum having a clutch drum attached thereto. Mounted within the clutch drum and rotatable with an actuating cover is a pair of substantially radially movable clutch shoes, each positioned with respect to one cam surface of a double acting cam fastened to the shaft. The actuating cover includes an overcenter toggle device operating in conjunction with the shaft to encourage the cover to either one of two stable positions, causing one or the other of the clutch shoes to engage the associated cam surface of the double acting cam to force the shoe firmly against the clutch drum. Rotation in one direction is allowed however, as such rotation allows the cam surface to release pressure on the clutch shoe, whereas attempted rotation in the opposite direction causing a locking action.
