Abstract
Abstract An apparatus for exercising the thigh, hamstring, and groin muscles, including structure for applying a predetermined weight to the upwardly extending leg to thereby stretch the hamstring and thigh muscles of a person lying on his back. The weights are attached to the person''s upwardly extending ankle by use of a cord and pulley system, and a one-way clutch enables the lifting of the weights by use of a cord with the hands and arms, then transferring the force of the weights to the leg to be exercised, thereby relieving the arms of the task of applying the force to the leg. A pair of pads are resiliently retained in laterally spaced relation so that a person using the device may position the pads between his knees and force them together against the resilient force to exercise his leg and groin muscles. A lazy tong device connected to the resilient arms has a curved plate adapted to engage the user''s abdomen to enable the user to apply greater resistance to movement of the pads, as desired.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
221 words
In a leg muscle exercising apparatus including a horizontal platform upon which a user may lie in a supine position and an upwardly extending stanchion at one end of said platform adapted to support a harness assembly for applying lifting and stretching forces to an upwardly lifted leg of the user lying on said platform, the improvement wherein said harness assembly Comprises, pulley means rotatably mounted on said stanchion at a position substantially above said platform, a first cord mounted on said pulley means and having one end extending in the direction of said platform in position to be grasped and pulled by said user, a second cord having one end adapted to be connected to the raised leg of said user, means connecting the other end of the second cord to said first cord for movement therewith in a direction tending to raise and thereby stretch the muscles of the user''s leg when the leg is attached to said second cord, manually energized moveable force applying means, and means connecting said force applying means to the other end of said first cord whereby manually pulling on said one end thereof energizes said force applying means and upon release thereof said force applying means applies a predetermined force tending to raise the user''s leg which is attached to said second cord.
Claim 2
Dependent Claim
221 words
In a leg muscle exercising apparatus including a horizontal platform upon which a user may lie in a supine position and an upwardly extending stanchion at one end of said platform adapted to support a harness assembly for applying lifting and stretching forces to an upwardly lifted leg of the user lying on said platform, the improvement wherein said harness assembly Comprises, pulley means rotatably mounted on said stanchion at a position substantially above said platform, a first cord mounted on said pulley means and having one end extending in the direction of said platform in position to be grasped and pulled by said user, a second cord having one end adapted to be connected to the raised leg of said user, means connecting the other end of the second cord to said first cord for movement therewith in a direction tending to raise and thereby stretch the muscles of the user''s leg when the leg is attached to said second cord, manually energized moveable force applying means, and means connecting said force applying means to the other end of said first cord whereby manually pulling on said one end thereof energizes said force applying means and upon release thereof said force applying means applies a predetermined force tending to raise the user''s leg which is attached to said second cord.
Claim 3
Dependent Claim
81 words
The leg muscle exercising apparatus as defined in claim 1 wherein said moveable force applying means comprises a plurality of weight members superimposed on top of one another, and wherein said means for releasably connecting said force applying means comprises means for releasably connecting any one of the individual weights to said first cord whereby the weights stacked thereabove are constrained to move upwardly with the attached weights when said one end of said first cord is pulled by said user.
Claim 4
Dependent Claim
38 words
The leg muscle exercising apparatus as defined in claim 2 wherein said stanchion is inclined upwardly and away from said horizontal platform, and further comprises guide means for guiding said weights along an inclined path along said stanchion.
Claim 5
Dependent Claim
40 words
The leg muscle exercising apparatus as defined in claim 1 wherein said means connecting said other end of said second cord for movement with said first cord comprises one-way clutch means, said pulley being operably connected with said clutch means.
Claim 6
Dependent Claim
