Abstract
Abstract 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).

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
139 words
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.
Claim 2
Dependent Claim
139 words
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.
Claim 3
Dependent Claim
52 words
