Abstract
Abstract A contrivance for exercising one''s limbs during times of immobility, wherein a carriage is movable on a frame along a reciprocal path against the resistance of a resilient member and the carriage also has structure to vary the position of the resilient member''s attachment to the carriage so as to vary the force required to move the carriage along said path in accordance with manual selection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
In a physiotherapeutic contrivance having a frame adapted to be supported uPon a surface proximate to an invalid; a carriage reciprocally moveable on said frame over a predetermined path; an improved variable tensioning means comprising: an endless elastic band; a pair of pulleys spaced laterally of the direction of movement of said carriage and fixed at one end of said frame for rotation about vertical axes and substantially in the same horizontal plane; a pulley rotatable about a vertical axle releasably fixed at one of plural anchoring points on said carriage spaced along the direction of movement of said carriage for rotation substantially in said plane; and said band trained about said pulleys.
Claim 2
Dependent Claim
113 words
