Abstract

The invention is a lifting device for attachment to an ATV which can utilize a small motor or crank, such as a boat crank, in order to carry a belt over a pulley system between the ATV frame and a platform to lift an object from the platform resting on the ground to the platform raised above the luggage rack platform on the rear of the ATV. The lifting platform may have a lifting plate floor which carries the load over (or on top of) the ATV rear luggage rack. The platform may be equipped with a removable or an extendable wheel so that it may function as a cart when the wheel is attached or extended.

Claims

1. A lifting device for lifting a load having a length and a width, said device attachable to a vehicle having a frame with a front and a rear said rear having a top, a bottom, and said rear having an attachment means for attaching a lifting platform between the rear top and the rear bottom, said frame further comprising a rear luggage platform having a length and a width capable of supporting the load, said platform extending from the frame rear towards the frame front and said vehicle further comprising wheels located at least partially below the rear luggage platform, said wheels supporting said frame above the ground, and said vehicle further defining a seat between the rear luggage platform and the frame front comprising:

a) a lifting platform having an attachment end and an angle end and wherein the attachment end has a length and wherein the attachment end is pivotally connected to the frame attachment means and wherein the length of the platform attachment end is at least equal to the distance between the frame attachment means and the rear top, said platform further comprising a floor having a front, a rear, a top, a bottom, a length and a width, said floor having a floor end attached to the angle end, and wherein the floor further comprises a lifting plate attached to the floor top between the floor front and the floor rear.

2. The invention of claim 1 wherein the floor further comprises at least two arms with at least one axle running between the arms so that the load may be held over the at least one axle and between theat least two arms while the platform lifted.

3. The invention of claim 1 wherein the plate floor is above and approximately parallel to the rear luggage platform when the platform plate is pivoted upward so that the plate may hold the load over the vehicle rear luggage platform when the floor is raised.

4. A lifting device for lifting a load having a length and a width, said device attachable to a vehicle having a frame, said frame having a front and a rear, said rear having a top and a bottom and said rear further having an attachment means for attaching a lifting platform between the rear top and the rear bottom, and a rear luggage platform having a length and a width extending from the rear top towards the frame front, said vehicle further comprising wheels located at least partially below the rear luggage platform, said wheels holding said frame above the ground, and said vehicle further defining a seat between the luggage platform and the frame front comprising:

a) a lifting platform having an attachment end and an angle end and wherein the attachment end is pivotally connected to the frame attachment means and wherein the length of the platform attachment end is at least equal to the distance between the frame attachment means and the rear top and further comprising a floor having a top and a bottom, a length and a width, said floor connected to the angle end so that when the floor is raised it extends above the rear luggage platform and wherein the frame comprises a left side and a right side and wherein the invention further comprises a first outrigger attached to the left side of the frame and extendable from the frame on the left side to the ground and a second outrigger attached to the right side of frame and extendable from the frame on the right side to the ground.
