Abstract
Abstract Stair climbing exercising apparatus for use under water comprising a pair of laterally adjacent stepping levers pivotally mounted between the two ends of the levers, the exerciser stepping on one end, and water resistance imposing member mounted the levers. The amount of water resistance being imposed is adjustable. In another embodiment, a paddle wheel is employed with blades along the outer periphery being adjustable to vary the amount of water resistance.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
Stair climbing apparatus for use by an exerciser comprising: a. support frame means including a ground engaging base immersed in water; b. a pair of laterally adjacent foot stepping levers pivotally mounted on said support frame means at a location above said base, c. synchronizing means mounted on said support frame means attached to each of said stepping levers so that when one of said levers is pushed down by said exerciser the other said lever is raised; and d. resistance means mounted on said stepping levers for relying on said water to resist pivotal movement of said stepping levers said apparatus being sufficiently immersed so that the water level is above said resistance means, said resistance means comprises a paddle; whereby said stepping levers are extended with said exerciser standing on the proximal ends of said levers, said levers being pivoted at points intermediate of the proximate and distal ends thereof, and said resistance means being mounted on the distal ends of said levers.
Claim 2
Dependent Claim
165 words
Stair climbing apparatus for use by an exerciser comprising: a. support frame means including a ground engaging base immersed in water; b. a pair of laterally adjacent foot stepping levers pivotally mounted on said support frame means at a location above said base, c. synchronizing means mounted on said support frame means attached to each of said stepping levers so that when one of said levers is pushed down by said exerciser the other said lever is raised; and d. resistance means mounted on said stepping levers for relying on said water to resist pivotal movement of said stepping levers said apparatus being sufficiently immersed so that the water level is above said resistance means, said resistance means comprises a paddle; whereby said stepping levers are extended with said exerciser standing on the proximal ends of said levers, said levers being pivoted at points intermediate of the proximate and distal ends thereof, and said resistance means being mounted on the distal ends of said levers.
Claim 3
Dependent Claim
61 words
The stair climbing apparatus of claim 1 wherein said peddle has having a stationary member and a member slidable with respect to said stationary member, each of said members having openings, said slidable member having means to adjust the overlapping of the openings in said stationary and slidable members to adjust the resistance as said stepping levers pivot within said water.
Claim 4
Independent Claim
187 words
The method of exercising comprising the steps of: a. immersing stair climbing apparatus in water, said stair climbing apparatus comprising support frame means including a ground engaging base, a pair of laterally adjacent foot stepping levers pivotally mounted on said support frame means at a location above said base, said stepping levers being extended with said levers being pivoted at points intermediate the proximate and distal ends of said levers, means mounted on said support frame means attached to each of said stepping levers to synchronize the movement of said levers, and resistance means mounted on the said stepping levers for relying on said water to resist pivotal movement of said stepping levers, said apparatus being immersed sufficiently to cover said resistance means said resistance means comprises a paddle; whereby said stepping levers are extended with said exerciser standing on the proximal ends of said levers, and said resistance means being mounted on the distal ends of said levers; and b. stepping on the proximal ends of said levers to produce reciprocal motion of said levers with resistance by said water being introduced by said resistance means.
Claim 5
Independent Claim
187 words
The method of exercising comprising the steps of: a. immersing stair climbing apparatus in water, said stair climbing apparatus comprising support frame means including a ground engaging base, a pair of laterally adjacent foot stepping levers pivotally mounted on said support frame means at a location above said base, said stepping levers being extended with said levers being pivoted at points intermediate the proximate and distal ends of said levers, means mounted on said support frame means attached to each of said stepping levers to synchronize the movement of said levers, and resistance means mounted on the said stepping levers for relying on said water to resist pivotal movement of said stepping levers, said apparatus being immersed sufficiently to cover said resistance means said resistance means comprises a paddle; whereby said stepping levers are extended with said exerciser standing on the proximal ends of said levers, and said resistance means being mounted on the distal ends of said levers; and b. stepping on the proximal ends of said levers to produce reciprocal motion of said levers with resistance by said water being introduced by said resistance means.
Claim 6
Dependent Claim
25 words
The method of claim 3 in which the level of said water is adjusted to control the amount of body weight being supported while exercising.
