Patent ID: 7874965

Claim:
Gymnastic machine ( 1 ) comprising a frame ( 10 ), at least one gymnastic implement ( 20 ) supported by said frame ( 10 ) to provide, in association with a load group ( 30 ), a resistive load to said at least one implement ( 20 ) during the execution of a physical exercise; wherein said load group ( 30 ) includes a first circuit ( 40 ) and a second circuit ( 50 ), both having respective first and second transmission members ( 41 ) ( 51 ); each said first and second transmission members ( 41 ) ( 51 ) including a flexible member ( 41 ) ( 51 ); said at least one implement ( 20 ) being coupled to a first transmission member ( 41 ) for said first circuit ( 40 ) and said second circuit ( 50 ) including at least one load unit ( 60 ) capable of exerting a resistive action on said first transmission member ( 41 ); said first circuit ( 40 ) and said second circuit ( 50 ) being interfaced mechanically with each other through modulating means ( 70 ) capable of mechanically activating said at least one load unit ( 60 ) to regulate its intensity in a substantially continuous manner; said modulating means ( 70 ) including at least one modulating element ( 71 ) capable of generating a shear action on said second circuit ( 50 ); wherein said at least one modulating element ( 71 ) supports a pulley member ( 71 ) having respective tangential coupling means ( 72 ) interfaceable with said second circuit ( 50 ) adjacent to a respective transmission member ( 51 ) to activate said load unit ( 60 ).
