International ClassA63B 021/06AbstractA weight-lifting machine having engaging means such as a barbell that is advanceable by a use both vertically and horizontally. The weight-lifting machine includes a base and a vertical support structure extending upward therefrom. A pair of first pivotal members are pivotally secured to the vertical support structure at an upper end thereof. Each of a pair of second pivotal members are pivotally connected to each of the first pivotal members and engaging means such as a barbell, curl-bar or handles are removably securable to the second pivotal members. Through the cooperation of the pivotal action of the first pivotal members and the second pivotal members, a user may grasp or otherwise engage the engagement means and advance the engagement means through simultaneous vertical and horizontal motion. Telescoping beams extending from the vertical support structure to the second pivotal members restrict the range of pivotal motion of the second pivotal members and provide resistance to the pivoting of the second pivotal members so as to provide greater control to a user. | |
