Abstract
Abstract An exercising device for conditioning the dorsal flexor muscles includes a fixed frame having inclined foot rests mounted adjacent one end and an arm arrangement swingably attached to the fixed frame at an opposite end. The arm arrangement includes a lever arm pivotally connected to the fixed frame and with foot engaging bars extending transversely from the lever arm generally adjacent the foot rest. The user places his feet between the foot rest and the foot engagement bars and flexes the feet upwardly to reduce the tendency toward the strained muscle condition known as shin splints. Provision is made for extra weights to be attached to the arm arrangement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
A lower leg exercising device comprising: (a) a fixed frame including a longitudinal frame member and front and rear frame end members extending transversely, said fixed frame generally lying flat upon a floor; (b) spaced foot rests mounted to said front end member and having a foot supportive surface inclined toward said rear end member; said foot rests being spaced about said longitudinal frame member; and having a lever arm and pivot means extending from said rear end member; said lever arm being rotatable toward and away from said longitudinal frame member; (d) foot engaging bars with rotative sleeves thereon extending transversely from said lever arm generally adjacent said front end member; said bars being spaced from said foot rests a distance sufficient for a foot to be positioned therebetween whereby when said foot is flexed, said arm arrangement swings upwardly; and (e) a weight holder positioned intermediately on said lever arm and including an upright shaft for receiving disc weights.
Claim 2
Dependent Claim
161 words
A lower leg exercising device comprising: (a) a fixed frame including a longitudinal frame member and front and rear frame end members extending transversely, said fixed frame generally lying flat upon a floor; (b) spaced foot rests mounted to said front end member and having a foot supportive surface inclined toward said rear end member; said foot rests being spaced about said longitudinal frame member; and having a lever arm and pivot means extending from said rear end member; said lever arm being rotatable toward and away from said longitudinal frame member; (d) foot engaging bars with rotative sleeves thereon extending transversely from said lever arm generally adjacent said front end member; said bars being spaced from said foot rests a distance sufficient for a foot to be positioned therebetween whereby when said foot is flexed, said arm arrangement swings upwardly; and (e) a weight holder positioned intermediately on said lever arm and including an upright shaft for receiving disc weights.
Claim 3
Dependent Claim
164 words
A lower leg exercising device comprising: (a) a fixed frame including a longitudinal frame member and front and rear end members extending transversely; (b) spaced foot rests mounted to said front end member and having a foot supportive surface inclined toward said rear end member; (c) an arm arrangement swingably attached to said fixed frame and having a lever arm and pivot means extending generally from said rear end member; said lever arm being rotatable toward and away from said longitudinal frame member; (d) foot engaging bars extending transversely from said lever arm generally adjacent said front end member; said bars being spaced from said foot rests a distance sufficient for a foot to be positioned therebetween whereby when said foot is flexed, said arm arrangement swings upwardly and provides weight to exercise the muscles of said lower leg; and (e) a weight holder mounted intermediately on said lever arm and including a base and an upright shaft extending therefrom for receiving disc weights.
Claim 4
Dependent Claim
164 words
A lower leg exercising device comprising: (a) a fixed frame including a longitudinal frame member and front and rear end members extending transversely; (b) spaced foot rests mounted to said front end member and having a foot supportive surface inclined toward said rear end member; (c) an arm arrangement swingably attached to said fixed frame and having a lever arm and pivot means extending generally from said rear end member; said lever arm being rotatable toward and away from said longitudinal frame member; (d) foot engaging bars extending transversely from said lever arm generally adjacent said front end member; said bars being spaced from said foot rests a distance sufficient for a foot to be positioned therebetween whereby when said foot is flexed, said arm arrangement swings upwardly and provides weight to exercise the muscles of said lower leg; and (e) a weight holder mounted intermediately on said lever arm and including a base and an upright shaft extending therefrom for receiving disc weights.
Claim 5
Dependent Claim
33 words
