Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
A jogging device comprising a frame having an arcuate upper surface, a horizontal completely rigid jogging platform freely suspended within and by same frame, means for yieldingly mounting the platform within the frame comprising a plurality of spring means, each of said spring means comprising in series combination a cantilever spring and a coil spring, said cantilever spring being attached to the arcuate upper surface of the frame and extending inwardly toward the platform, and said coil spring having one end thereof attached to the inward portion of the cantilever spring and the other end thereof attached to the platform.
Claim 2
Dependent Claim
100 words
A jogging device comprising a frame having an arcuate upper surface, a horizontal completely rigid jogging platform freely suspended within and by same frame, means for yieldingly mounting the platform within the frame comprising a plurality of spring means, each of said spring means comprising in series combination a cantilever spring and a coil spring, said cantilever spring being attached to the arcuate upper surface of the frame and extending inwardly toward the platform, and said coil spring having one end thereof attached to the inward portion of the cantilever spring and the other end thereof attached to the platform.
Claim 3
Dependent Claim
43 words
The jogging device of claim 1 wherein the cantilever springs comprise slat springs which are attached to the outer periphery of the arcuate upper frame surface such that the spring extends over the apex of the frame curvature and inwardly toward the platform.
Claim 4
Dependent Claim
29 words
The jogging device of claim 1 also comprising fastening means for attaching the cantilever spring to the frame, and fastening means for attaching the coil spring to the platform.
Claim 5
Dependent Claim
31 words
The jogging device of claim 1 also comprising a plurality of resilient feet mounted on the underside of the frame and adapted to support the frame in a level, horizontal position.
Claim 6
Dependent Claim
49 words
The jogging device of claim 1 wherein the cantilever spring and the coil spring have relative spring characteristics such that as increasing downward force is exerted on the platform from an unstressed condition, the cantilever spring bends substantially to its limit prior to the coil spring having substantial extension.
Claim 7
Dependent Claim
31 words
The jogging device of claim 1 wherein the rigid platform is covered with a pad of closed-cell soft foam rubber having a thickness of from about 3/4 to about 11/4 inches.
