Abstract
A multipurpose loading and unloading apparatus for installation on a pickup truck bed or the floor of a vehicle cargo area. The inventive apparatus includes a load-bearing member, such as a cargo box, having at least a slide board panel with an upper load-bearing side and a lower roller-engaging side. A roller mount is disposed under the slide board panel and includes, at a minimum, opposing and parallel guide rails. A roller assembly is interposed between the slide board panel and the roller mount, and it is tethered to the roller platform at a pivot point forward from the center of gravity of the load-bearing member. As the load-bearing member is moved rearwardly, it reaches a point at which it is tilted naturally when unloaded, and with little effort when loaded.

A multipurpose loading and unloading apparatus for installation on a pickup truck bed or the cargo area floor of a vehicle, said apparatus comprising:
- a load-bearing member having a slide board panel with an upper load-bearing side and a lower roller-engaging side, a front portion, a rear portion, and first and second pivot points;
- a roller mount disposed under said slide board panel comprising opposing and parallel longitudinally disposed guide rails, said roller mount having a front portion and a rear portion and first and second connection points disposed on said guide rails;
- first and second tilt inducing means connected to said load-bearing member at said first and second pivot points;
- a roller assembly interposed between said roller-engaging side of said load-bearing member and the vehicle or truck bed;
- a locking lever disposed at said front portion of said load-bearing member to secure said load-bearing member until it is desired that it be rolled backwards;
- wherein said vehicle attachment means comprises seat belt straps attached to said roller mount, said straps having at least one of said buckles and clips for matable connection to an existing vehicle seat belt system in the vehicle.
A multipurpose loading and unloading apparatus for installation on a pickup truck bed or the cargo area floor of a vehicle, said apparatus comprising:
- a load-bearing member having a slide board panel with an upper load-bearing side and a lower roller-engaging side, a front portion, a rear portion, and first and second pivot points;
- a roller mount disposed under said slide board panel comprising opposing and parallel longitudinally disposed guide rails, said roller mount having a front portion and a rear portion and first and second connection points disposed on said guide rails;
- first and second tilt inducing means connected to said load-bearing member at said first and second pivot points;
- a roller assembly interposed between said roller-engaging side of said load-bearing member and the vehicle or truck bed;
- wherein said roller assembly comprises a substantially rectangular frame having two side rails, a plurality of cylindrical transverse rails disposed between and connecting said side rails, and a plurality of rollers axially disposed on at least two of said transverse rails.
A multipurpose loading and unloading apparatus for installation on a pickup truck bed or the cargo area floor of a vehicle, said apparatus comprising;
- a load-bearing member having a slide board panel with an upper load-bearing side and a lower roller-engaging side, a front portion, a rear portion, and first and second pivot points;
- a roller mount disposed under said slide board panel comprising opposing and parallel longitudinally disposed guide rails, said roller mount having a front portion and a rear portion and first and second connection points disposed on said guide rails;
- first and second tilt inducing means connected to said load-bearing member at said first and second pivot points;
- and
- a roller assembly interposed between said roller-engaging side of said load-bearing member and the vehicle or truck bed;
- wherein said roller mount includes a roller platform having an upper surface upon which said roller assembly is disposed, and a lower surface for placement on the pickup truck bed or the cargo floor area of the vehicle, and side rails attached to said roller platform such that said roller assembly is interposed between said side rails and between said upper surface of said roller platform and said roller-engaging surface of said load-bearing member.
