Abstract
Abstract A loading and unloading apparatus for a van of a type including a framework within the van for slideably supporting a beam. A winch is moveably disposed on the beam for allowing an object to be loaded to be hoisted upwardly when the beam and hoist extend outside of the van; and, then the object can be moved into the van by movement of the beam into the van and movement of the winch and object along the beam in the same direction. Once the object is properly positioned within the van, it can be lowered to the floor of the van for support. Upon reaching the destination for the object, the winch is again used to raise the object off of the floor, whereupon the object is manually pushed out of the van causing movement of the beam and movement of the winch along the beam. Once the object is outside of the van, it can then be lowered to the ground by further use of the winch.

Claim 1
Independent Claim
294 words
An apparatus for loading and unloading heavy objects to and from a van having a loading door opening therein, comprising: a U-shaped framework having a central portion, a first leg portion connected to one end of the central portion and extending to the floor of the van and a second leg portion connected to the other end of said central portion and extending to the floor of the van, said U-shaped framework being positioned adjacent to said van loading door opening whereby said legs are positioned on each side of said van loading door opening; a support post in abutment with the floor of the van at the bottom thereof and extending upwardly; an elongated beam being I-shaped in cross-section; means for slideably attaching said beam to a top portion of said support post including a sleeve means for receiving said beam and allowing the beam to slide within said sleeve means; support means connected to the top of said sleeve means and to the top of the central portion of the U-shaped member for stabilizing said apparatus. means for slideably attaching said beam to the central portion of said U-shaped member; winch means connected to said beam for selectively raising heavy objects towards said beam and lowering said heavy objects away from said beam, including means for attaching an object to be lifted to said winch means; roller means for attaching said winch means to said beam for allowing said winch to be moveable along said beam; and stop means connected to said beam for allowing movement of said beam with respect to said framework between a first position whereby said beam extends out of said van loading door opening to a second position whereby said beam is located entirely within said van.
