Abstract
Abstract An apparatus for loading and unloading a personal water craft into the bed of a conventional pick-up truck which only requires a single operator. The device includes a support frame mountable to the bed of a pick-up truck which supports at least one telescopic, pivotal ramp assembly. The ramp assembly including first and second sections which are telescoped together so as to extend and form an elongated ramp. The first ramp section is pivotally secured at its rear to the rear of the support frame by a hinge assembly. The hinge assembly allows the first and second sections to pivot together and also functions to guide the second ramp section as it slides along a channel in the length of the first ramp section. In operation the personal water craft or personal watercraft is secured at its bow to a winch cable and pulled on a sled on the second ramp section, once on the sled the second ramp section travels along the first ramp section while the weight of the personal watercraft causes the ramp assembly to pivot downward until it lies in a horizontal plane.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
195 words
A device for loading and unloading objects, comprising: a support frame including a front end and a rear end; a ramp including a first ramp member having a rear end pivotally attached to said support frame at said rear end of said support frame and extending forward toward said front end of said support frame and a second ramp member telescopically secured to said first ramp member permitting said second ramp member to travel the length of said first ramp member and to pivot therewith, said second ramp member including a bow stop projecting upwardly at a forward end of said second ramp member to limit movement of an object on said second ramp member; a sled rigidly mounted to and spaced above said second ramp member for receiving the object thereon; and a winch system mounted approximate said front end of said support frame, said winch system including a cable for attachment to the object, wherein said cable passes over at least one roller on said bow stop of said second ramp member permitting the second ramp member to be moved relative said first ramp member to facilitate loading and unloading of the object.
