Abstract
Abstract A device for the partial simulation of climbing includes a frame having a vertically adjustable step and an upstanding handle to permit the user to simulate climbing by stepping up and down the step. Continuous or full simulation of climbing is achieved by a device which has vertically movable steps so that the user may remain at one location while continuously going through the motions of stepping upward.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
278 words
A device for the continuous simulation of climbing comprising a pair of upstanding A-shaped frames pivotally connected at their upper ends to a bridging member, right step means mounted to one of said frames for up and down movement in accordance with the user selectively applying weight on the right foot of the user which in turn is placed on said right step means, left step means mounted to the other of said frames juxtaposed said right step means for up and down movement in accordance with the user selectively applying weight on the left foot of the user which in turn is placed on said left step means, each of said A-frames comprising a pair of legs interconnected by adjustable locking means for permitting said legs to be juxtaposed each other during the inactive condition of said device and for varying the angle between said legs during the operative condition of said device to control the angle of climb of the user, a sleeve slidably mounted on one leg of each of said frames, each of said step means being a step mounted in a cantilevered manner to a respective one of said sleeves, resistance means reacting against said right step means and said left step means opposing the force applied by the user selectively stepping on said right step means and said left step means, a cable adjustably secured at one end to each of said sleeves in such a manner that the effective length of said cable may be varied to control the height of its respective step, and said resistance means reacting against said cable to thereby provide a resistance force to said steps.
Claim 2
Independent Claim
278 words
A device for the continuous simulation of climbing comprising a pair of upstanding A-shaped frames pivotally connected at their upper ends to a bridging member, right step means mounted to one of said frames for up and down movement in accordance with the user selectively applying weight on the right foot of the user which in turn is placed on said right step means, left step means mounted to the other of said frames juxtaposed said right step means for up and down movement in accordance with the user selectively applying weight on the left foot of the user which in turn is placed on said left step means, each of said A-frames comprising a pair of legs interconnected by adjustable locking means for permitting said legs to be juxtaposed each other during the inactive condition of said device and for varying the angle between said legs during the operative condition of said device to control the angle of climb of the user, a sleeve slidably mounted on one leg of each of said frames, each of said step means being a step mounted in a cantilevered manner to a respective one of said sleeves, resistance means reacting against said right step means and said left step means opposing the force applied by the user selectively stepping on said right step means and said left step means, a cable adjustably secured at one end to each of said sleeves in such a manner that the effective length of said cable may be varied to control the height of its respective step, and said resistance means reacting against said cable to thereby provide a resistance force to said steps.
Claim 3
Dependent Claim
39 words
The device of claim 1 wherein hand grip means extend upwardly from each of said upstanding frames and adjustable resistance means secured to said hand grip means for providing exercise to the user's arms while performing the climbing exercise.
Claim 4
Dependent Claim
60 words
The device of claim 1 wherein a pulley is mounted at the upper end of each of said frames, said resistance means being mounted to said bridging member, and said cable for said steps being a common cable extending from one of said steps over said pulleys and engaging said resistance means and extending to the other of said steps.
Claim 5
Dependent Claim
13 words
The device of claim 3 wherein said resistance means is a friction brake.
