Abstract
A stair climbing exercise apparatus for use within a pool of water comprises two steps mounted for reciprocal movement along vertically disposed guides, pulleys disposed at an upper end of the guides, and a cable interconnecting the two steps and extending around the pulleys. Mounted on each of the steps, for movement therewith, is a flap having a relatively large surface disposed perpendicularly to the direction of movements of the steps. In use, when one of the steps is moved downwardly by the foot of a user of the apparatus, the other step is moved upwardly by the interconnecting cable. The water resists movement of the flaps, hence provides resistance to downward movement of the steps.
Claims7
An exercise stair-like device for use within a body of water comprising two parallel adjacent tracks inclined from the vertical, the two tracks having a lower end and an upper end with the lower end of the parallel tracks being intended to rest on the bottom of the body of water and the upper end of the parallel tracks extending above the bottom, two steps and guide means one step per track, said steps being reciprocally movable along adjacent paths defined by said tracks, means interconnecting said two steps, upon movement of one of said steps downwardly in response to a force exerted thereon by a user of the device, the other of said steps is moved upwardly, and a flap means mounted on each of said steps and extending laterally therefrom, each of said flap means having a surface disposed generally perpendicular to the direction of movements of said steps, whereby in use of said device within a body of water, the water provides resistance to movements of said flaps along said direction and a corresponding resistance to movements of said steps along said direction.
