Exercising device for use with a wheelchair

A device for connection to a wheelchair to enable exercising by a user of the wheelchair or to enable propelling of the wheelchair, said device comprising:

• (a) a generally upright structure,
• (b) an axle mounted in said upright structure,
• (c) a driven wheel mounted on said axle for rotation,
• (d) a hand operated crank mechanism on said generally upright structure and being operativelyconnected to said axle for causing rotation of a said wheel when cranked,
• (e) a foot operated crank mechanism on said generally upright structure and being operatively connected to said axle for causing rotation of said wheel when cranked,
• (f) means for raising said wheel for free rotation to enable exercising by operating one or both of said crank mechanisms and lowering said wheel into a ground surface for causing propelling movement of the wheelchair, and
• (g) connecting means for releasably connecting said device to the wheelchair, said connecting means being adjustably positionable on said generally upright structure to adjust the angle of the generally upright structure about the axle with respect to the wheelchair.

A connecting assembly for connecting an exercising device to a wheelchair, said connecting assembly comprising:

• (a) a cross-bar provided for transverse location across a portion of a frame of a wheelchair,
• (b) means associated with said cross-bar to enable adjustment of the transverse dimension of said cross-bar to enable fitting to different sized wheelchairs,
• (c) first means intermediate the ends of said cross-bar to enable two sections of said cross-bar to be pivotal intermediate its ends and thereby enable collapsing of said wheelchair when said cross-bar is attached,
• (d) a connecting arm having a first pivotal connecting means at one end for pivotal connection to said cross-bar and a second pivotal connecting means for pivotal connection to an exercising device, and
• (e) attachment means on each of the ends of said cross-bar for releasable attachment to a frame of the wheelchair.

A device for connection to a wheelchair to enable exercising by a user of the wheelchair or to enable propelling of the wheelchair, said device comprising:

• (a) a generally upright structure,
• (b) an axle mounted in said upright structure,
• (c) a driven wheel mounted on said axle for rotation,
• (d) a hand operated crank mechanism on said generally upright structure and being operatively connected to said axle for causing rotation of said wheel when cranked,
• (e) a foot operated crank mechanism on said generally upright structure and being operatively connected to said axle for causing rotation of said wheel when cranked,
• (f) means for raising said wheel for free rotation to enable exercising by operating one or both of said crank mechanisms and lowering said wheel into a ground surface for causing propelling movement of the wheelchair, said means for raising comprising a stand having a pair of stand members on opposite sides of said wheel for supporting said device as a stand alone unit independently of a wheelchair, and
• (g) connecting means for releasably connecting said device to the wheelchair.
