An foldable exercise device comprising:
- elongated rear support structure having a rear floor engaging portion, said rear support structure being constructed and arranged to extend upwardly and forwardly of said rear floor engaging portion when the latter is disposed in operating relation in contact with a floor surface,
- front support structure having a front floor engaging portion, said front support structure being pivotally coupled to said rear support structure at a coupling location so as to be disposed in operative relation in a position extending downwardly and forwardly of the coupling location to the front floor engaging portion in operating relation in contact with the floor surface,
- each of said rear and front floor engaging portions having an extent sufficient to engage the floor surface at laterally spaced portions when disposed in operating relation to provide stability to the rear and front support structures when in operative relation,
- a seat support structure pivotally coupled to said rear support structure at a pivot location so as to be disposed in operative relation in a position extending rearwardly from the pivot location, said seat support structure having a seat fixedly mounted thereon in a position spaced from the pivot location thereof,
- said seat support structure being constructed and arranged to be moved in said operative relation in opposite directions about its pivot location so that the seat moves arcuately upwardly and downwardly with the seat support structure within a range of operative movements between a lower limiting position wherein said seat is spaced above said rear support structure therebelow and an upper limiting position spaced above said lower limiting position,
- an elongated lever structure pivotally connected to said rear support structure at a connection location so as to be disposed in operative relation in a position forwardly of the pivot location of said seat support structure, said lever structure in said operative relation having an upper portion extending upwardly from the connection location and a lower portion extending downwardly from the connection location,
- said lever structure including foot supports coupled to the lower portion thereof, and a handlebar coupled to said upper portion of said lever structure and disposed forwardly of said seat,
- said lever structure being constructed and arranged to be moved in opposite directions about its connection location within a range of operative movements corresponding to the range of operative movements of said seat support structure, and
- a connecting link structure pivotally connected between said lever structure and said seat support structure, said connecting link structure being constructed and arranged such that when said lever structure is moved about its connection location by a person seated on said seat by hand and foot movements on said handlebar and foot supports respectively, said seat support structure pivots about its pivot location within said range of operative movements so that the upwardly arcuate movements of said seat away from said lower limiting position are resisted by the weight of the person seated on said seat,
- said structures and the interconnection therebetween being constructed and arranged to permit (1) said front and rear support structures to be pivoted relative to one another about said coupling location into a storage position wherein said front support structure is generally alongside said rear support structure and (2) the lower portion of said lever structure and said seat support structure to be moved beyond the range of the operative movements thereof into a storage position disposed generally alongside said rear support structure.
