Abstract:
Apparatus for facilitating loading upon and conveyance by a carrier of cargo; said carrier including compartment means and passage means communicating with said compartment means; said apparatus comprising four members; each said member including an approximately flat bottom section and an approximately flat side section which meet each other at an approximately right angle so as to define an approximately linear junctional edge; said four members consisting of a first member pair and a second member pair; said first member pair being adaptable to association with said compartment means so that the corresponding said bottom sections are situated approximately in the same imaginary approximately horizontal plane and so that the corresponding said side sections are approximately parallel with respect to each other; said second member pair being adaptable to association with said passage means so that the corresponding said bottom sections are situated approximately in the same imaginary inclined plane and so that the corresponding said side sections are at least substantially oblique with respect to each other; each said member being characterized by an interior right angle; for each said member pair, said interior right angles being generally oppositely disposed in relation to each other; said cargo includes wheel means; said first member pair consisting of a first left member and a first right member; said second member pair consisting of a second left member and a second right member; said first left member having a said bottom section which is a first left bottom section; said first right member having a said bottom section which is a first right bottom section; said second left member having a said bottom section which is a second left bottom section; said second right member having a said bottom section which is a second right bottom section; said first left member having a said side section which is a first left side section; said first right member having a said side section which is a first right side section; said second left member having a said side section which is a second left side section; said second right member having a said side section which is a second right side section; said first left bottom section having a first left upper surface and a first left lower surface; said first right bottom section having a first right upper surface and a first right lower surface; said second left bottom section having a second left upper surface and a second left lower surface; said second right bottom section having a second right upper surface and a second right lower surface; said first left side section having a first left outside surface and a first left inside surface; said first right side section having a first right outside surface and a first right inside surface; said second left side section having a second left outside surface and a second left inside surface; said second right side section having a second right outside surface and a second right inside surface; said first member pair being adaptable to association with said compartment means so that said wheel means is positionable in said compartment means upon at least a portion of said first left upper surface and at least a portion of said first right upper surface; said second member pair being adaptable to association with said passage means so that movement of said wheel means over said passage means is delimited by at least a portion of said second left inside surface and at least a portion of said second right inside surface; said apparatus further comprising adjustment means, for adjusting at least one of:the distance between said first left inside surface and said second left inside surface; and the distance between said first left outside surface and said second left outside surface.
