Abstract

A device for simulating climbing includes a pair of side frames each of which has a pair of upper legs into which a pair of lower legs are telescoped. A horizontal platform is connected to the upper legs whereby the effective height of the platform may be adjusted by the degree of telescoping of the lower legs into the upper legs.

Claims

1. A device for simulating climbing comprising a pair of side frames, each of said side frames comprising a pair of upper legs connected together at their upper ends, a lower leg telescoped into each upper leg, a horizontal platform connected to said upper legs, a series of openings in each of said upper legs, each of said openings being arranged in the same plane as a corresponding opening in all of the other of said upper legs to provide a number of sets of openings corresponding to the number of openings in each series, a pin resiliently mounted to each lower leg for selective engagement with a respective opening whereby the height of said platform may be controlled, a pair of cross-pieces, each of said cross-pieces being connected to a respective upper leg in each of said side frames, said platform being mounted to said cross-pieces, said upper legs of each of said side frames being pivotally mounted to each other, and said platform being completely detachably mounted to one of said cross-pieces and pivotally mounted to the other of said cross-pieces whereby said device may be stored in a collapsed condition during periods of nonuse with said platform parallel to and spaced from said other cross-piece.

7. The device of claim 1 wherein said openings are in the form of elongated slots, resilient means reacting between each upper leg and its respective lower leg to urge said platform in an upward direction, the upper edge of each respective slot acting as a stop member for its said pin to limit the upward movement of said platform and the lower edge of each of said slots acting as a stop member to limit the downward movement of said platform when a user steps on said platform to overcome the resilient force of said resilient means.

8. The device of claim 7 wherein said openings further comprise circular openings disposed remote from said slots, and said lower legs being rotatably mounted in said upper legs whereby the user may select either said slots or said circular openings as the openings into which said pins may be engaged.

2. A device for stimulating climbing comprising a pair of side frames, each of said side frames comprising a pair of upper legs connected together at their upper ends, a lower leg telescoped into each upper leg, a horizontal platform connected to said upper legs, a series of openings in each of said upper legs, each of said openings being arranged in the same plane as a corresponding opening in all of the other of said upper legs to provide a number of sets of openings corresponding to the number of openings in each series, a pin resiliently mounted to each lower leg for selective engagement with a respective opening whereby the height of said platform may be controlled, a pair of cross-pieces, each of said cross-pieces being connected to a respective upper leg in each of said side frames, said platform being mounted to said cross-pieces, said upper legs of each of said side frames being pivotally mounted to each other, said platform being completely detachably mounted to one of said cross-pieces and pivotally mounted to the other of said cross-pieces whereby said device may be stored in a collapsed condition during periods of nonuse, said openings being in the form of elongated slots, resilient means reacting between each upper leg and its respective lower leg to urge said platform in an upward direction, the upper edge of each respective slot acting as a stop member for its said pin to limit the upward movement of said platform and the lower edge of each of said slots acting as a stop member to limit the downward movement of said platform when a user steps on said platform to overcome the resilient force of said resilient means.

3. The device of claim 2 wherein said openings further comprise circular openings disposed remote from said slots, and said lower legs being rotatably mounted in said upper legs whereby the user may select either said slots or said circular openings as the openings into which said pins may be engaged.

4. The device of claim 3 wherein said platform is mounted to one of said cross-pieces by means of U-brackets, and said platform being detachably mounted to the other of said cross-pieces by a spring clip.

5. The device of claim 4 including cushioned tips at the exposed ends of said upper and lower legs.

6. The device of claim 5 including a curved connecting member connecting a respective upper leg to the other of said upper legs in each of said side frames.
