ABSTRACT:
A boat loader and unloader has a vertical post which is mounted on the rear of a vehicle. A carriage is slidably and pivotally mounted on the top of the post by rollers. A reel assembly having a crank-operated, cable take-up tube is removably mounted transversely across the midportion of a boat. A cable is attached to and extends between the reel tube and carriage which is clamped to the boat transom. Acutation of the crank-operated reel tube winds the cable about the tube raising the boat from the ground to a position where the boat and carriage then can be pushed forwardly on the rollers to move the boat and carriage to a forward storage position on top of the vehicle. A reverse operation enables an individual to manually unload the boat from on top of the vehicle. An improved conrol mechanism is mounted on the reel and includes a plurality of spring-biased camming rollers which are engaged between ramp surfaces formed on a band brake and a stub shaft attached to the take-up reel. The camming rollers permit free rotation of the stub shaft and cable take-up tube when manually rotating the tube in one direction to load the boat on the vehicle. The rollers function as a brake and prevent rotation of the reel tube in the opposite direction until a pair of straight legs on the band brake are spread further apart by an intervening, manually actuated control lever, permitting the weight of the boat to unwind the cable take-up tube, lowering the boat from its raised position on the vehicle to the ground. In an alternate arrangement actuation of the control lever in a second direction moves the band brake legs closer together to prevent any possible brake slippage during loding and unloading of the boat.
