Abstract

An exercise device having a seat assembly that includes a seat, and a seat frame extending forwardly of the seat and connected to a frame assembly, and a seat-support arm pivotally mounted to the seat frame, the arm having attached at its lower end a follower that is movably engageable with a subjacent surface. A linkage is pivotally connected to a leg-actuated member pivotally connected to an upper front frame portion, and is pivotally connected to the seat-support arm. An arm-actuated member is pivotally connected to the linkage between the pivotal connections of the linkage with the leg-actuated member and the seat-support arm, and is pivotally related with the upper front frame portion. The arm-actuated member and the leg-actuated member are pulled and pushed respectively by the arms and legs of a user sitting on the seat to pivot the seat-support arm and to move the seat-support follower forwardly on the subjacent surface, and thereby raise the seat against the weight of the user, the user's weight tending to move the seat-support follower rearwardly on the subjacent surface and thereby lower the seat.

Claims1

Dependent claims

An exercise device, comprising:

(a) a frame means including a floor-engaging front portion, and an upper front portion having a bearing bar,
(b) a seat means including:
(1) a seat rearwardly of the upper frame portion, and
(2) a seat frame extending forwardly of the seat and pivotally connected to the frame means,
(c) a seat-support means including:
(1) an arm pivotally mounted to the seat frame, and extending downwardly and rearwardly, and
(2) a follower on the arm pivotally engaging a subjacent surface,
(d) a leg-actuated means pivotally connected to the upper front frame portion, and extending downwardly, the leg-actuated means including a pair of foot-engaging members,
(e) linkage means pivotally connected to the leg-actuated means and pivotally connected to the seat-support arm, and
(f) arm-actuated means including a handle bar pivotally connected to the linkage means between the pivotal connections of the linkage means with the leg-actuated means and the seat-support arm, and both pivotally and slidably engaging the bearing bar of the upper front frame portion for moving the handle bar upwardly and downwardly relative to the bearing bar to accommodate the movement of the linkage means,
(g) the arm-actuated means and the leg-actuated means being pulled and pushed respectively by the arms and legs of a user sitting on the seat to pivot the seat-support arm and move the follower forwardly on the subjacent surface, and thereby raise the seat means against the weight of the user, the user's weight tending to move the seat-support follower rearwardly on the subjacent surface and thereby lower the seat means.
