Abstract

An exercising device for simulating climbing includes a base with a resisting device secured thereto for attachment to the legs of the user and a vertically adjustable step on the base on which the user would step up and down in opposition to the resisting device.

Claims

1. An exercising device for simulating the action of climbing comprising a base, resisting means secured to said base having means for attachment to the legs of the user to provide a force resisting movement of the user away from said resisting means, a step on said base spaced generally within a normal stride distance from said resisting means so as to receive the foot of a user during an action against said resistance means, said step including an upper platform and downwardly depending side walls, and vertical adjusting means cooperating with said side walls for vertically adjusting the height of said platform above said base.

2. The device of claim 1 including a support member mounted to said base, said support member having a pair of parallel upstanding side walls for cooperating with positioning means on said platform side walls, securing means cooperating with said positioning means for securing said platform side walls to said upstanding side walls after said platform has been mounted in its predetermined position, and said vertical adjusting means comprising said positioning means and said securing means.

3. The device of claim 2 wherein said positioning means includes a plurality of sets of holes in said upstanding side walls and a pair of holes in said platform side walls, and said securing means comprising detachable fasteners for insertion into said holes when said platform side wall holes are aligned with corresponding holes in said upstanding side walls.

4. The device of claim 3 wherein said platform is horizontally mounted with respect to said upstanding side walls.

5. The device of claim 4 wherein the leading edge of said platform is padded.

6. The device of claim 3 wherein said platform is mounted in an inclined position with respect to said upstanding side walls.

7. The device of claim 1 including rail means disposed above said step whereby the user may grasp said rail means.

8. The device of claim 7 wherein said rail means is vertically and horizontally adjustable.

9. The device of claim 8 wherein said rail means includes a pair of vertically mounted tubes secured to said base, a vertical rod telescopically received in each of said vertical tubes, a horizontal tube secured at the upper end of each of said vertical rods, a U-shaped rail having its free ends telescopically received in said horizontal tubes, and fastening means for locking said vertical tubes and said rail in place after adjustment thereof.

10. The device of claim 1 wherein said resisting means comprises a pair of spaced springs, each of said springs being secured at one end to said base and having attachment means at its other end for attachment to the ankles of the user.

11. The device of claim 10 including adjustable anchoring means to vary the location and angle of said springs.

12. The device of claim 11 wherein said attachment means includes a collar, and detachable securing means on said collar for attachment to the user'"'"'s ankles.

13. The device of claim 12 wherein each of said collars is padded, and said detachable securing means comprises Velcro.

14. The device of claim 3 including rail means disposed above said step whereby the user may grasp said rail means, said rail means being vertically and horizontally adjustable, said resisting means comprising a pair of spaced springs, each of said springs being secured at one end to said base and having attachment means at its other end for attachment to the ankles of the user, adjustable anchoring means varying the location and angle of said springs, and said attachment means including a collar and detachable securing means on said collar for attachment to the user'"'"'s ankle.

15. A method of simulating climbing comprising the steps of vertically adjusting a platform a selected distance above a base, securing the platform in position, mounting resilient resistance means to the base, attaching the resistance means to the ankles of the user, stepping up on to the platform one foot at a time in opposition to the force of the resilient resistance means, stepping down from the platform one foot at a time, and repeating the stepping up and stepping down.

16. The method of claim 15 including horizontally and vertically adjusting the position of a rail secured to the base above the step.

17. The method of claim 16 wherein the step of securing the platform in position includes securing the platform in a horizontal position parallel to the base.

18. The method of claim 16 wherein the step of securing the platform in position includes securing the platform in an inclined position at an angle to the base.
