Patent ID: 8771154

Claim:
An exercise device ( 1 ) comprising: a frame ( 10 ), a load group carried by said frame ( 10 ); said load group ( 20 ) including an elongated arch-shaped elastic body ( 30 ) connected to said frame ( 10 ) and a flexible member ( 40 ) connected to said arch-shaped elastic body ( 30 ); wherein said arch-shaped elastic body ( 30 ) includes a first end portion ( 32 ) and a second end portion ( 33 ), and wherein said flexible member ( 40 ) is coupled between said first end portion ( 32 ) and said second end portion ( 33 ), respectively, so as to maintain said flexible member ( 40 ) tensioned both at rest and in use, during the execution of a training exercise; a coupling means ( 12 ) for coupling said frame with an intermediate portion ( 36 ) of said arch-shaped elastic body; said coupling means ( 12 ) including a base ( 120 ) adapted to couple rigidly to a fixed body (P)(W); wherein said load group includes a handle member ( 34 ) associated with said flexible member ( 40 ) to facilitate the gripping thereof according to a direction transverse to a longitudinal axis ( 41 ) of said flexible member ( 40 ), so as to facilitate the application of a tensile stress to said elastic body ( 30 ) during the execution of a training exercise; wherein said intermediate portion ( 36 ) of said arch-shaped elastic body is substantially equidistant from said respective end portions ( 32 ) ( 33 ); wherein said coupling means ( 12 ) includes a guiding member ( 124 ) coupled rigidly to said fixed body (P)(W) and a slide ( 126 ) coupled to said guiding member ( 124 ); wherein said arch-shaped elastic body ( 30 ) is connected to said slide ( 126 ) for adjusting an arrangement of said arch-shaped elastic body ( 30 ) along said guiding member ( 124 ); and wherein said arch-shaped elastic body ( 30 ) is connected to said slide ( 126 ) through a second joint ( 18 ) for allowing transverse movements of the arch-shaped elastic body ( 30 ) relative to said guiding member ( 124 ).
