Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
245 words
A device for passively exercising the arms and legs of a person who has difficulty moving these limbs, said device comprising: a base platform; right and left arm exercising members, each comprising an elongated shaft, pivotally connected to the base platform at the bottom of each shaft, each of said arm exercising members having handles; right and left leg exercising members affixed to a driven shaft, said driven shaft having a first pair of generally U-shaped bends formed therein, said first pair of bends being foot supporting bends, each bend including a base, said bends being positioned at 180 degrees from one another and said driven shaft being supported by said base platform, said leg exercising members having foot attachment means rotatingly affixed thereto at the base of said U-shaped foot supporting bends; link members hingedly affixed between said arm exercising members at a point removed from their point of pivotal connection to said base platform and a second pair of opposed U-shaped arm oscillating bends formed in said driven shaft and pivotally connected at the base of said arm oscillating bends, the base of said second pair of U-shaped bends being oriented at about 180 degrees from each other so that the arms and legs of the user are moved in a predetermined, unison movement; and motor means connected to said driven shaft to rotate said shaft about its longitudinal axis, whereby said arm and leg exercising members are oscillated thereby exercising the user.
Claim 2
Independent Claim

Claim 3
Dependent Claim
17 words
The device of claim 1 wherein the platform is shaped to permit a wheelchair to rest thereon.
Claim 4
Dependent Claim
19 words
The device of claim 1 further including foot holding means attached to the right and left leg exercising members.
Claim 5
Dependent Claim
14 words
The device of claim 1 wherein said motor means is a variable speed motor.
Claim 6
Dependent Claim
52 words
The device of claim 1 wherein the right and left arm exercising members are both pivotally connected to said base platform in front of said driven shaft whereby the resulting arm movement is such so that when one of a user's arms is extended, the other of a user's arms is contracted.
