Patent ID: 7710062

Claim:
A driver with a reverse-rotation preventer for an inflatable rotating exhibit comprising a base having an inner side; a motor mount being mounted in the inner side of the base and having a lower surface; and an upper surface; a hole being formed longitudinally in the motor mount; and a preventer bracket being a cylinder, being mounted securely on the lower surface of the motor mount, protruding in from the motor mount, co-axially around the hole and having an outer surface; a synchronous motor being mounted on the upper surface of the motor mount, rotating in a direction when the driver operates, reversing direction when the drive encounters an even temporary resistance and having a shaft being keyed, being connected to and driven by the synchronous motor and being mounted rotatably through and extending out in the hole of the base; a reverse-rotation preventer being annular, being mounted co-axially around the preventer bracket, being axially slidable and rotationally secure relative to the preventer bracket, and having an inner surface; a distal end; and at least one pawl protruding longitudinally from the distal end of the reverse-rotation preventer and having a stop protruded longitudinally from the distal end of the reverse-rotation preventer and having a distal edge; and an inclined surface connecting to the distal edge of the stop and the distal end of the reverse-rotation preventer; and a rotating assembly being mounted coaxially securely around and being driven by the shaft, abutting the preventer bracket, holding the reverse-rotation preventer and having a center; a base plate being formed in the center of the rotating assembly and keeping the reverse-rotation preventer from falling; and at least one opening being formed in the base plate, corresponding to the at least one pawl to allow the pawl to drop into the opening and having a radial edge.
