Abstract
Abstract An adjustable, recoiling aerobic exercise bench (20) which reduces the generation and transmission of impaction forces on a user's joints while performing conventional and power step exercises including a resilient platform (22) slidingly disposed in a left and right housings (36 and 38) which function to support the platform (22) above and relative to an exercise floor surface (42); a lateral platform recoiling assemblies is disposed between the platform ends (24 and 26) and inside lateral walls of the housings (36, 38) and adapted to generate lateral, resistive, restoring forces when platform (22) is moved downward during operation of the device (20); vertical platform recoiling assemblies (62), which includes a plurality of rigid tubular spring retainers, telescoping springs (90) mounted the undersurface of the platform and of sufficient length so as to make contact with the exercise floor surface (42) to thereby generate a vertical platform resistive restoring force when platform (22) is downwardly compressed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
223 words
An exercise device comprising: a platform having a thickness, a top side, a bottom side, a first edge and a second edge extending along a length dimension, and a third edge and a fourth edge extending along a width dimension; a left housing having a top wall, a bottom wall, a first side wall and a second side wall, the housing extending along the third edge of the platform and the second side wall having a first channel of predetermined height and length formed therein; a right housing having a top wall, a bottom wall, a first side wall and a second side wall, extending along the fourth edge of the platform, the second side wall having a first channel of pre-determined height and length formed therein; the third edge and fourth edge of the platform each having a retainer bar attached thereto each retainer bar having a cross-sectional dimension greater than the thickness of the platform, and of the height of said first channels, respectively; and a floor surface engagable vertical recoil assembly positioned on the bottom side of the platform intermediate said third edge and said fourth edge and including means to resist forces applied to the platform from the direction of its top side to its bottom side sufficient to function as a platform resistive and restoring force during operation.
Claim 2
Dependent Claim
223 words
An exercise device comprising: a platform having a thickness, a top side, a bottom side, a first edge and a second edge extending along a length dimension, and a third edge and a fourth edge extending along a width dimension; a left housing having a top wall, a bottom wall, a first side wall and a second side wall, the housing extending along the third edge of the platform and the second side wall having a first channel of predetermined height and length formed therein; a right housing having a top wall, a bottom wall, a first side wall and a second side wall, extending along the fourth edge of the platform, the second side wall having a first channel of pre-determined height and length formed therein; the third edge and fourth edge of the platform each having a retainer bar attached thereto each retainer bar having a cross-sectional dimension greater than the thickness of the platform, and of the height of said first channels, respectively; and a floor surface engagable vertical recoil assembly positioned on the bottom side of the platform intermediate said third edge and said fourth edge and including means to resist forces applied to the platform from the direction of its top side to its bottom side sufficient to function as a platform resistive and restoring force during operation.
Claim 3
Dependent Claim
29 words
The exercise device of claim 1 wherein the platform is convex with the third and fourth edges closer to the support surface than the center portion of the platform.
Claim 4
Dependent Claim
62 words
The exercise device of claim 1 wherein the left and right housings are of trapezoidal cross-section, with the bottom wall of the left housing and bottom wall of the right housing having a width greater than the width of the top wall, so as to provide greater surface area on the bottom of the housing than on the top of each housing.
Claim 5
Dependent Claim
53 words
The exercise device of claim 1 further including first and second lateral recoil assemblies positioned in the left and right housings, respectively, between the first side wall and the channel of each housing, respectively, and including means to resist lateral forces applied to the third edge retainer bar and fourth edge retainer bar.
Claim 6
Dependent Claim
14 words
The exercise device of claim 1 wherein the vertical recoil assembly includes a spring.
Claim 7
Dependent Claim
21 words
The exercise device of claim 5 wherein the spring further includes a stopper mounted between any two coils of the spring.
Claim 8
Dependent Claim
15 words
The exercise device of claim 6 wherein the stopper is made of an elastomeric material.
Claim 9
Dependent Claim
35 words
The exercise device of claim 6 wherein the spring is retained by an upper tube member and a lower tube member, the upper and lower tube members adapted for telecoping relationship each to the other.
Claim 10
Dependent Claim
49 words
The exercise device of claim 8 further including a stop member mounted on the lower tube and adapted to limit the downward displacement of the platform during use of the device by abutment of a lower end of the upper tube with the top surface of the stop member.
Claim 11
Dependent Claim
69 words
The exercise device of claim 1 further including a plurality of left and right risers, the risers each having a top wall, a bottom wall, a first side wall and a second side wall, each left riser having a cross-sectional configuration substantially identical to the cross-sectional configuration of the left housing, and each right riser having a cross-sectional shape substantially identical to the cross-sectional shape of the right housing.
Claim 12
Dependent Claim
74 words
The exercise device of claim 10 wherein the top wall of the left riser and top wall of the right riser each include a tongue-shaped mounting element formed thereon, extending along the length of the riser corresponding to the third edge and fourth edge of the platform, respectively, and the tongue shape adapted to the slidingly retained within a complimentary shaped groove on the bottom wall of the left housing and right housing, respectively.
