<p>The invention relates to a multifunctional weight-training gym machine in which tensile forces are supplied in an optimal manner and applied, by means of levers (48), to cables (34) which use pulley systems (49, 50, 51, 52, 53, 54) in order to be selectively connected by adapters (26) to one of the ramps (22 and 35) that are loaded with discs (16). The machine is formed by two towers joined by crossbars (9 and 59). Each tower includes a bottom platform (1) and a top platform (55) which, by means of screws (7) and coupling elements (10), are connected to vertical pillars (5), side pillars (4), three-leg stands (17) and two-leg stands (41), (42). The aforementioned platforms (1) and (55) include supports (11), (14), (43), (45) which secure rails (12) and (15) and other supports (18 and 56) which secure rails (21). A pulley system (49, 50, 51, 52, 53, 54) is secured at each platform (55) and at the corresponding crossbars (59), and pulley systems (49) and (52) can move along rails (12) and (15), allowing the cable (34) to be suitably adjusted. Ramps (22) and (35) slide on rails (21), secured inside the towers by supports (18) and (56). A central, mobile, removable ramp slides on the lower crossbars (9), said ramp having a structure formed by various stationary and hinged elements, including a plate (62) that connects to a folding system for a pulley (87), and mobile plates (63) which facilitate access to the elements located on the crossbars (59). The crossbars (59) are connected to: reinforcing plates (112), rings (107), supports (121), supporting bars (125), which, by means of press members, secure bars (126) and (127), and ladders with rungs (119).</p> |
