Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
164 words
A leg exercising and conditioning device comprising in combination a supporting frame, a pair of collapsible foot receiving means for receiving the feet of a user, said means including components wherein each of said components is pivotally connected to said frame at one end of each of said components, a force resistance means connected between each of said articulated components and said frame for resisting the swinging movement of each of said articulated components in one direction, a foot engaging member on each of said collapsible components adapted to receive the foot of the user, each of said articulated components including an inner member pivotally mounted at one end thereof to said supporting frame, for movement in only a horizontal plane, and an outer member journalled by one end thereof to the other end of said inner member, said outer member having means for permitting movements of said inner member in a vertical plane and in a horizontal plane relative to said inner member.
Claim 2
Dependent Claim
164 words
A leg exercising and conditioning device comprising in combination a supporting frame, a pair of collapsible foot receiving means for receiving the feet of a user, said means including components wherein each of said components is pivotally connected to said frame at one end of each of said components, a force resistance means connected between each of said articulated components and said frame for resisting the swinging movement of each of said articulated components in one direction, a foot engaging member on each of said collapsible components adapted to receive the foot of the user, each of said articulated components including an inner member pivotally mounted at one end thereof to said supporting frame, for movement in only a horizontal plane, and an outer member journalled by one end thereof to the other end of said inner member, said outer member having means for permitting movements of said inner member in a vertical plane and in a horizontal plane relative to said inner member.
Claim 3
Dependent Claim
66 words
