Abstract

A device for simulating climbing includes a support structure having a platform detachably secured thereto. A spacer is insertable between the support structure and the platform and in accordance with the position of the spacer the effective height of the platform may be adjusted. The spacer has different horizontal and vertical dimensions which provide height adjustability of the platform depending upon the orientation of the spacer.

Claims

1. A device for simulation of climbing comprising a support unit, said support unit having a plurality of legs, a base secured to the top of said legs whereby said base may selectively function as a lowermost step on to which and from which a user may step during a simulated climbing exercise, a platform selectively disposed above and detachably connected to said base to provide an alternate step, and at least one spacer being selectively disposed between and detachably connected to said base and said platform for varying the distance said platform extends above said base to thereby permit the user to selectively adjust the height of the step;

a plurality of said spacers being selectively positioned between said platform and said base, said spacers each having different horizontal and vertical dimensions and selectively mounted in one of two positions between said platform and said base, wherein a first hole extends through said horizontal dimension of said spacer and a second hole extends through said vertical dimension of said spacer, and a pin being mounted between said base and said platform and selectively extending through one of said holes of said spacer.

2. The device of claim 1 wherein one of said spacers is located at each end of said platform and extends completely across said platform.

3. The device of claim 2 including a mounting block secured to said platform at each end thereof selectively disposed against a respective spacer, and said pin being mounted to each of said blocks.

4. The device of claim 3 wherein each of said mounting blocks includes a pair of spaced recesses covered by said platform to create a pair of pockets, each of said pins extending through a respective mounting block and terminating in an enlarged head trapped in a respective pocket, and the opposite end of each pin extending through a respective hole in said base.

5. The device of claim 4 including a spring detachably mounted around each of said pins to provide a resilient force urging said platform away from said base.

6. The device of claim 5 wherein said legs are hingedly mounted to said base to permit said support unit to be in a collapsed condition.

7. The device of claim 1 including resilient means between said platform and said base urging said platform away from said base.
