Abstract
The present invention provides a frame that supports a pair of simulator skis above a floor surface. Rear ski ends are pivotally mounted to a rear ski support in rolling contact with a track surface on a rear frame portion. Front ski ends are pivotally mounted to a front ski support in rolling contact with the floor surface. Non-parallel, equal length bars are disposed on opposite sides of the pair of skis, extending from rear bar ends pivotally mounted to the base to front bar ends pivotally mounted to the front ski support.
Claims25
An exercise apparatus designed to rest upon a floor surface, comprising a base that supports a track surface above the floor surface, a pair of skis that extend from rear ski ends to front ski ends, wherein each rear ski end is supported by a rear ski support which is carried by at least one rear roller that engages the track surface, and each front ski end is supported by a front ski support which is carried by at least one front roller that engages the floor surface, and a first elastic band segment extends between the rear ski support and a first band support proximate a first end of the base, and a second elastic band segment extends between the rear ski support and a second band support proximate a second, opposite end of the base.
An exercise apparatus designed to rest upon a floor surface, comprising a base that supports a track surface above the floor surface, a pair of skis that extend from rear ski ends to front ski ends, wherein each rear ski end is supported by a rear ski support which is carried by at least one rear roller that engages the track surface, and each front ski end is supported by a front ski support which is carried by at least one front roller that engages the floor surface, and a pair of bars disposed on opposite sides of the pair of skis and extending between rear bar ends that are pivotally secured to the base, and front bar ends that are pivotally secured to opposite sides of the front ski support.
A downhill skiing simulator having a frame, a pair of simulator skis extending from a rear portion of the frame to a front portion of the frame, wherein the frame includes a pair of bars disposed on opposite sides of the skis and having respective rear bar ends pivotally mounted to said rear portion of the frame, and respective front bar ends pivotally mounted to opposite sides of said front portion of the frame and each supported by a front roller.
A downhill skiing simulator, comprising a pair of simulator skis having ski front ends and ski rear ends, a front bar that supports said ski front ends, a rear bar that supports said ski rear ends, and a pair of non-parallel, equal length side bars having bar front ends and bar rear ends, wherein said side bars are disposed on opposite sides of said pair of simulator skis, and said bar front ends are pivotally connected to said front bar, and said bar rear ends are pivotally connected to said rear bar, and said front bar is free to move relative to said rear bar along a path determined by said side bars.
