Abstract A bicycle type of exercising device for paraplegic invalids comprising an elongated structure having one end adapted to rest upon the floor and its other end adapted to rest upon the end of a conventional bed. Handle bar means and seat support means are mounted upon the end resting upon the floor to provide a manual operator station. The latter end is also provided with a first bicycle sprocket which is operably connected by a link chain to a second sprocket operably connected to the other end of the elongated structure. The second sprocket means is provided with pedal means adapted to receive and retain the feet of a paraplegic who is horizontally disposed in the bed on which the present device is operably mounted whereby the invalid can pedal the present device alone, or preferably, his legs can be exercised by an operator pedaling at the other end provided with the manual station. A preferred embodiment further comprises an auxiliary electric power source operably connected to the link chain for actuating the present device in the absence of manual operation by an operator. An especially preferred embodiment is directed to an electric power driven only device having a supporting bicycle structure adapted for mounting solely upon the bedstead.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A paraplegic exercising device comprising: a. frame means having hub portions at both of its ends adapted to receive rotating sprocket means; b. first sprocket means rotatably mounted in one of the hub portions of said frame means; c. second sprocket means rotatably mounted in the opposite hub portion of said frame means and adapted to receive the feet of a paraplegic to be administered physical therapy; d. sprocket connecting means operably connecting said first and second sprocket means together whereby rotation of one sprocket causes the other sprocket to rotate; and e. clamping means operably attached to the end of said frame means provided with said second sprocket means adapted for connection to the feet of a paraplegic to receive physical therapy, said clamping means being further defined in that it is adapted to fit and rest upon the edge of a bed in which the paraplegic is positioned in alignment with said second sprocket means.
Claim 2
Dependent Claim
157 words
A paraplegic exercising device comprising: a. frame means having hub portions at both of its ends adapted to receive rotating sprocket means; b. first sprocket means rotatably mounted in one of the hub portions of said frame means; c. second sprocket means rotatably mounted in the opposite hub portion of said frame means and adapted to receive the feet of a paraplegic to be administered physical therapy; d. sprocket connecting means operably connecting said first and second sprocket means together whereby rotation of one sprocket causes the other sprocket to rotate; and e. clamping means operably attached to the end of said frame means provided with said second sprocket means adapted for connection to the feet of a paraplegic to receive physical therapy, said clamping means being further defined in that it is adapted to fit and rest upon the edge of a bed in which the paraplegic is positioned in alignment with said second sprocket means.
