Abstract:
An exercise machine (10) comprising:a resistance member (44) mounted on a frame and a first pulley (80) operatively connected to the resistance member; second (78), third (84) and fourth (82) pulleys mounted on the frame; a first cable (52) engaged with the first, second, third and fourth pulleys, the pulleys and cable operable to operate the resistance member responsive to the first cable (52) being pulled by a first end away from the third pulley (84) or being pulled from a second end away from the second pulley (78); the first cable (52) having first and second retainers mounted on the respective first and second ends of the cable, the first retainer (60) preventing the first cable end from disengaging from the third pulley (84), the second retainer (79) preventing the second cable end from disengaging from the second pulley (78); the frame including left and right vertical frame members; left (26) and right (28) sliding brackets mounted on the respective left and right vertical frame members; a fifth pulley (66) mounted on the left side of the frame and a sixth pulley (49) mounted on the right side of the frame; a seventh pulley (64) mounted on the left sliding bracket, and an eighth pulley (58) mounted on the right sliding bracket; a ninth pulley (70) above the fifth pulley (66) and a tenth pulley (51) above the sixth pulley (49), and a second cable (50) connecting the ninth and tenth pulleys to an eleventh pulley (76) mounted on the first cable second end; a third cable (46) engaged with the fifth, seventh and ninth pulleys, the first end of the third cable (46) connected to the left slidable connector (26) and the second end of the third cable operably engaged with the seventh pulley (64), the third cable (46) operable to raise the weight by pulling the second end of the third cable away from the seventh pulley (64), thereby pulling the second end of the first cable (52) away from the second pulley; and, a fourth cable (48) engaged with the sixth pulley (58), eighth pulley (49) and tenth pulley (51), and twelfth pulley (53), the first end of the fourth cable connected to the right slidable connector and the second end of the fourth cable (48) operably engaged with the sixth pulley (58), the fourth cable (48) operable to raise the weight by pulling the second end of the fourth cable away from the sixth pulley (58), thereby pulling the second end of the first cable (52) away from the second pulley (78).
