An apparatus (10) for movably mounting equipment (11) on a wheelchair (12) having an armrest (12a) and a back support (12b), which comprises first and second pivot assemblies (20, 21), a longitudinal body member (40) spacing and joining the first and second pivot assemblies (20, 21) and rotatable about a fixed axle (50) of the first pivot assembly (20). There may also be provided a device (22) to attach the fixed axle (50) to the wheelchair (12), a rotatable axle (51) in the second pivot assembly (21) supporting the equipment (11), and an assembly such as pulleys (80, 81) and a cable (83) for rotating the rotatable axle (51) as a function of the rotation of the body member (40) relative to the fixed axle (50). Rotation of the body member (40) relative to the fixed axle (50) effects rotation of the rotatable axle (51) such that the equipment (11) remains orthogonal to the armrest (12a) of the wheelchair (12) during movement from a position in front of the wheelchair (12) to a position to the rear of the back support (12b) of the wheelchair (12). |

DETAILED DESCRIPTION What is claimed is: 1.
Apparatus for movably mounting equipment on a wheelchair having an armrest and a back support, comprising first and second pivot means, a longitudinal body member spacing and joining said first and second pivot means and rotatable about a fixed axle of said first pivot means, means to attach said fixed axle to the wheelchair, a rotatable axle in said second pivot means supporting the equipment, and means for rotating said rotatable axle as a function of the rotation of said body member relative to said fixed axle, whereby rotation of said body member relative to said fixed axle effects rotation of said rotatable axle such that the equipment remains orthogonal to the armrest of the wheelchair during movement from a position in front of the wheelchair to a position to the rear of the back support of the wheelchair.
2.
An apparatus as set forth in claim 1, wherein said means for rotating said rotatable axle as a function of the rotation of said body member relative to said fixed axle includes a first pulley affixed to said fixed axle, and a second pulley affixed to and rotatable with said rotatable axle.
3.
A device, as set forth in claim 2, wherein said first and second pulleys are connected via cable means.
4.
A device, as set forth in claim 3, wherein said body member comprises first and second conduits.
5.
A device, as set forth in claim 4, wherein said cable means is positioned within said first and second conduits.
6.
A device, as set forth in claim 1, wherein the equipment is supported by said rotatable axle via a laterally extending support arm.
7.
A device, as set forth in claim 6, wherein said laterally extending support arm is L-shaped and has first and second ends.
8.
A device, as set forth in claim 7, wherein said first end of said L-shaped support arm is affixed to the equipment, and said second end of said L-shaped support arm is affixed to said rotatable axle.
9.
A device, as set forth in claim 1, further comprising locking means for locking at least one of said pivot means in a preselected position
