Abstract
An aerobic exercise device featuring a vertically movable seat counter-balanced mainly by a spring. As a user, supported by the seat, executes a squatting exercise the seat will urge the user toward an initial position. The seat moves vertically along an upright column having a pulley at its top. A cable connects the seat to a spring at the back side of the column via the pulley. Handles are suspended from arms at the top of the column to help a user support his or her weight.
Claims12
A multipurpose exercise apparatus comprising,
- an upright rail column,
- a pair of arms mounted to said rail column, each arm being generally horizontal and having a handle suspended therefrom,
- a seat rollably mounted on said rail column, said seat having a vertical range of motion along said rail column, said seat being at a level below said arms, and
- adjustable restoring means operatively attached to said seat for applying a controllable upward restoring force to said seat, said force being proportional to the vertical displacement of said seat along said rail column and tending to restore the seat to a rest position.

A multipurpose exercise apparatus comprising,
- a support base,
- an upright column affixed to said base,
- a rollable frame mounted on said upright column for vertical motion along the column,
- a seat mounted on the rollable frame,
- a pair of arms mounted to the top of said rail column and extending horizontally out over the seat, said arms supporting a pair of handles suspended below said arms, said arms being vertically stationary relative to said upright column,
- a lever arm having an end pivotally connected to said column on a side opposite said seat,
- a spring tensioning assembly connected to said lever arm and to said base, and
- means for applying a restoring force to said seat, said means employing a mechanical advantage element to connect said spring tensioning assembly to said rollable frame via said lever arm, the upward restoring force applied to the seat being proportional to the distance said seat is vertically displaced from a rest position.

A multipurpose exercise apparatus comprising,
- a support base,
- an upright rail column attached to said support base,
- a pair of horizontal arms pivotably attached to the top of the rail column, said arms pivoting in a horizontal plane, said arms being vertically fixed,
- a pair of handles suspended below said horizontal arms, each handle suspended by a variable length of chain attached to one of said arms,
- a rollable frame mounted on said rail column, said frame being restrained to a vertical range of motion along the rail column,
- a seat movably mounted to said rollable frame,
- seat restoring means operatively attached to said seat for developing and applying an adjustable counter-balancing restoring force to the seat along the rail column, said restoring means having a rest condition, said seat having a rest position when said restoring means is in said rest condition, and
- adjustable means for selectively varying the height of said rest position of said seat, said adjustable means being an attachment of said seat to said restoring means.

A multipurpose exercise apparatus comprising,
- a support base,
- an upright column affixed to said base,
- a rollable frame mounted on said upright column for vertical motion along the column,
- a seat mounted on the rollable frame,
- a pair of arms mounted to the top of said rail column and extending horizontally out over the seat, said arms supporting a pair of handles suspended below said arms, said arms being pivotably mounted, the arms having a range of motion in a horizontal plane between a parallel position above the seat and an open position in which the arms are positioned on opposite sides of the rail column,
- a lever arm having an end pivotally connected to said column on a side opposite said seat,
- a spring tensioning assembly connected to said lever arm and to said base, and
- means for applying a restoring force to said seat, said means employing a mechanical advantage element to connect said spring tensioning assembly to said rollable frame via said lever arm, the upward restoring force applied to the seat being proportional to the distance said seat is vertically displaced from a rest position.
