Abstract
A ski exercising apparatus has a set of at least two parallel, partially arcuate rails joined to an underlying frame structure at opposite ends, the rails providing a track rising from each end, a wheeled carriage riding on the track, such that the carriage, in side-to-side movement rises to a maximum height at the center of the track, and descends from the center to each side, at least one articulated footpad mounted to the wheeled carriage, and at least one power band providing constraint for the wheeled carriage as it rides on the track. A variety of improvements in such an exercising apparatus are taught and claimed.
Claims14
A ski exercising apparatus, comprising:
- a set of at least two parallel, partially arcuate rails joined to an underlying frame structure at opposite ends, the rails providing a track rising from each end;
- a wheeled carriage riding on the rails, such that the carriage, in side-to-side movement rises to a maximum height at the center of the track, and descends from the center to each side;
- at least one power band attached to the carriage and engaging mechanisms mounted to the underlying frame structure at opposite sides of center of the track;
- a handgrip apparatus attached to the wheeled carriage, providing four handgrips in two sets of two, one set provided at a height higher than the other set, enabling a user to grasp the handgrip apparatus and thereby hand-operate the wheeled carriage in the side-to-side movement;
- and
- a substantially linear slide plate having spaced apart rounded rails extending in the direction of movement of the wheeled carriage, the slide plate mounting to the wheeled carriage, and at least one attachment plate having rounded grooves spaced-apart compatibly with the rounded rails, the attachment plate mounted to the linear slide plate by engaging the rounded grooves of the attachment plate with the rounded rails of the slide plate, the handgrip apparatus attached to the attachment plate.

- a wheeled carriage riding on the rails, such that the carriage, in side-to-side movement rises to a maximum height at the center of the track, and descends from the center to each side;
- at least one power band attached to the carriage and engaging mechanisms mounted to the underlying frame structure at opposite sides of center of the track;
- and
- at least one substantially planar interface for a user's feet joined to the wheeled carriage by a linear translation mechanism directed at a right angle to the side-to-side direction of travel of the wheeled carriage allowing limited free forward and backward motion of the user's feet in the direction of the translation mechanism, at a right angle to the direction of travel of the wheeled carriage.

- and
- at least one substantially planar interface for a user's feet joined to the wheeled carriage by an arcuate translation mechanism allowing limited arcuate motion of the interface about a pivotal axis located at a height greater than the height of a horizontal plane of the planar interface and extending in the direction of motion of the wheeled carriage.
