Recoiling exercise bench
First Claim
1. An exercise device comprising:
- an arcuate flexible platform having a top surface and a pair of ends, said platform being movable between an at-rest flexed position and an elongated position when a vertical force is applied on the top surface of the platform;
first and second end members, each of said end members having a housing with a flat bottom wall for supporting the device on a support surface, an inner wall, a pair of spaced end walls, and a slot formed in the inner wall and extending laterally between the end walls for slidably receiving the ends of the platform therein, each of the housing slots terminating prior to said end walls and defining end members for preventing lateral movement of the platform ends within said slots, said slots having a depth sufficient to permit the ends of the platform to move longitudinally into said slots when the vertical force is applied to said platform.

Abstract
An adjustable, recoiling aerobic exercise bench which reduces the generation and transmission of impaction forces on a user'"'"'s joints while performing conventional and power step exercises includes a resilient platform slidingly disposed in left and right housings which function to support the platform above and relative to an exercise floor surface. Lateral platform recoiling assemblies are disposed between the platform ends and inside lateral walls of the housings and are adapted to generate lateral, resistive, restoring forces when the platform is moved downward during operation of the device. A vertical platform recoiling assembly which includes a plurality of rigid tubular spring retainers and telescoping springs, is mounted beneath the undersurface of the platform and is of sufficient length so as to make contact with the exercise floor surface to generate a vertical platform resistive restoring force when the platform is downwardly compressed. The ends of the platform are freely movably mounted within the housings to permit longitudinal movement of the platform ends therein when a vertical force is applied to the platform.

11. An exercise device comprising:
-
first and second end members; an arcuate flexible platform having a top surface and a pair of ends; retention means for retaining each of the platform ends within a respective one of the end members and for permitting outward movement of said platform ends within said end members when a vertical force is applied on the top surface of said platform; vertical recoil assembly means positioned below the platform and intermediate the end members for resisting vertical forces acting on the top surface of said platform; and stretcher means extending between the end members for stabilizing the device, said stretcher means including a bar which extends through an aperture formed in the vertical recoil assembly means.
