## Abstract

A portable and foldable workhorse. A pair of parallel rails includes an open space between the rails, the rails providing a flat top support surface and a bottom support surface. A pair of leg assemblies each includes a top surface. A center beam is attached to each leg assembly so that each center beam is moveable in the open space between said pair of rails. A shaft passes through and perpendicular to the parallel rails and through and perpendicular to the center beam. The shaft pivotally connects each center beam to the rails to allow movement of each leg assembly between a usage position wherein the rail bottom support surface rests on the top surface of the leg assemblies and a storage position wherein the leg assemblies will move radially about a pivot point on the top rails.

## Claims

### Claim 1

A portable and foldable workhorse, which comprises:
a pair of parallel rails having an open space between said rails, said rails providing a flat top support surface to support a load and a bottom support surface;
a pair of leg assemblies, each said leg assembly having a pair of legs that converge to form a top surface;
a center beam attached to each said leg assembly, each said center beam movable between said pair of parallel rails in said open space, each said center beam having a flat top level with said rails top support surface when in a usage position an a notched out portion;
a brace attached and perpendicular to each said center beam, each brace affixed to and extending between said pair of converging legs, each brace fitting in said notched out portion of said center beam to transmit said load to said brace; and
a pair of shafts, each shaft passing through and perpendicular to said parallel rails and to said center beam, each said shaft pivotally connecting each said center beam to said rails to allow movement of each said leg assembly between a storage position wherein each said leg assembly is nearly parallel to said rails and said usage position wherein said rail bottom support surface rests on said top surfaces of said leg assemblies.

### Claim 2 (depends on 1)

A portable and foldable workhorse as set forth in claim 1 including a removable lock pin for each side leg assembly, said pin passing through said parallel rails and through said center beam to lock said leg assembly in the usage position.

### Claim 3 (depends on 1)

A portable and foldable workhorse as set forth in claim 1 including a hook attachable to at least one said parallel rail to provide a shelf lower than the level of said flat top support surface.

### Claim 4

A portable and foldable workhorse which comprises:
an elongated rail assembly having a pair of longitudinal open spaces, a flat top support surface to support a load and a bottom support surface;
a pair of leg assemblies, each said leg assembly having a pair of legs that converge to form a top surface;
a center beam attached to each said leg assembly, each said center beam moveable in one of said longitudinal open spaces, each said center beam having a flat top level with said rail assembly top support surface and a notched out portion;
a brace attached and perpendicular to each said center beam, each brace affixed to and extending between said pair of converging legs, each brace fitting in said notched out portion of said center beam to transmit said load to said brace; and
means to move each said leg assembly between a storage position wherein each said leg assembly is nearly parallel to said rails and a usage position wherein said bottom support surface rests on said top surfaces of said leg assemblies.

### Claim 5 (depends on 4)

A portable and foldable workhorse as set forth in claim 4 wherein said means to move each said leg assembly includes a bolt passing through and perpendicular to said rail assembly and leg assembly.

### Claim 6 (depends on 4)

A portable and foldable workhorse as set forth in claim 4 including a removable lock pin for each said leg assembly, said pin passing through said rail assembly and through said center beam to lock said leg assembly in the usage position.

### Claim 7 (depends on 4)

A portable and foldable workhorse as set forth in claim 4 including a hook attachable to said rail assembly to provide a shelf lower than the level of said flat top support surface.
