EXERCISE APPARATUS WITH A PULL CORD LOOPED ABOUT A CENTRAL PULLEY AND FIRST AND SECOND FREE PULLEYS

摘要

An exercise apparatus includes a frame, first and second free pulleys, first and second handle portions, first and second frame pulleys attached to the frame, a central pulley, a pull cord, and a resistance member. The first free pulley includes a first pulley wheel and a first hub with the first pulley wheel configured to rotate in relation to the first hub. The second free pulley includes a second pulley wheel and a second hub with the second pulley wheel configured to rotate in relation to the second hub. The first and second handle portions are in mechanical communication with the first and second hubs with the pulley wheels configured to rotate relative to the handle portions. The pull cord is looped about the pulleys with the resistance member configured to resist movement of the pull cord.

主权项

1. An exercise apparatus comprising:
a frame; a first free pulley including a first pulley wheel and a first hub with the first pulley wheel configured to rotate in relation to the first hub, the first free pulley not being attached to the frame; a first handle portion in mechanical communication with the first hub with the first pulley wheel configured to rotate relative to the first handle portion; a second free pulley including a second pulley wheel and a second hub with the second pulley wheel configured to rotate in relation to the second hub, the second free pulley not being attached to the frame; a second handle portion in mechanical communication with the second hub with the second pulley wheel configured to rotate relative to the second handle portion; a first frame pulley attached to the frame; a second frame pulley attached to the frame; a central pulley; a pull cord consecutively looped about the first frame pulley, the first free pulley, the central pulley, the second free pulley and the second frame pulley along the pull cord; and a resistance member in mechanical communication with the pull cord, the resistance member configured to resist movement of the pull cord with the pull cord being in tension; wherein the pull cord including first and second cord ends that are in mechanical communication with the resistance member, the resistance member being configured to resist movement of the first cord end in a direction away from the resistance member and of the second cord end in a direction away from the resistance member; andwherein the first free pulley only being in mechanical communication with the exercise apparatus via the pull cord, the second free pulley only being in mechanical communication with the exercise apparatus via the pull cord.
