Loading hoist for boats
Abstract
Abstract A hoist is attached to the rear of a vehicle (such as a pick-up truck) to lift a boat from the ground to the top of the vehicle. The hoist has two telescopic members which initially are flat on the ground in extended position. The lower ends of the telescopic members are braced to the vehicle (as by clamping to the rear bumper) and are pivoted to feet which rest on the ground and the lower telescopic members are cross-braced. The upper ends of the telescopic members are clamped to the gunwales near the stern of the boat. The boat rests upside down over the telescopic members with its prow near the rear of the vehicle. On the vehicle is a winch for a rope which passes over a pulley, then down to the ground, through a guide on the prow of the boat and thence to a point of attachment at the stern. As the winch is turned, the prow is lifted up to the pulley, the stern sliding on the ground toward the vehicle. For this purpose, wheels may be attached to the stern. As the stern moves toward the vehicle, the telescopic members contract. The prow slides forward on the top of the vehicle until it is horizontal. By a different arrangement of pulleys, the hoist and winch may be used to lower the boat to the ground.
