Abstract
Abstract A horizontal padded body-supporting bar is rigidly mounted to a pair of spaced, parallel, upright floor-standing stanchions and supports the weight of the user's body with the head, torso and upper limbs hanging inverted on one side of the bar and the legs on the other. Mounting brackets permit a pair of arms, carrying a leg restraining cross member, to be mounted to the stanchions extending either horizontally rearwardly or vertically upwardly of the body-supporting bar. For rigidity the stanchions may be provided with a pair of rails at their lower ends, or with mounting brackets adapted releasably to engage mating brackets attached to the jambs at the opposite sides of a doorway.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
137 words
A portable exercise and traction apparatus, comprising: a pair of spaced upstanding stanchions; spacing means bridgingly connected to said stanchions and rigidly maintaining them in parallel relationship; a horizontal body supporting member immovably mounted to said stanchions and adapted to support the full weight of the body upon the user's upper thighs; leg restraining means rigidly mounted to said stanchions, said restraining means including a cross member positioned generally parallel to, and spaced from said body supporting member for restraining engagement by the user's lower extremities when the user's upper body depends vertically from said body supporting member; stabilizing means associated with said stanchions for rigidly maintaining said stanchions in a vertical position; and mounting means on said stanchions for selectively positioning said leg restraining means alternatively in vertical or horizontal alignment with said body supporting member.
Claim 2
Dependent Claim
