A programmed skiing simulater, trainer and exerciser. The machine comprises an inclined board over which two simulated skiis move. Each of the skiis is both pivotable and slidable at one end on slide-ball-pivot points. The other end of each ski also rides on a similar ball-pivot point, mounted on a wheel carriage, enabling the ski end to swing in a wide curve from one side to the other, in a programmed arc. The skiis are provided with tubular slotted tracks underneath, thus permitting them to tilt from side to side and slide on the pivot points while turning. By interchanging the wheel carriages with a differently designed "avalement" wheel carriage different movements may be performed.

An exercising device for use in conditioning muscles used in the sport of skiing is disclosed. The exercising device may be used indoors or outdoors and is comprised of a platform with an oval shaped body secured beneath the platform. Suitable boot engaging clamps are provided on the platform and are used to secure a ski boot or the like to the platform. The exercising device permits lateral pivotal movement of the body as well as forward tilt.

The present invention relates to a ski training device which comprises a generally horizontal support plate, oscillating about a principal axis of symmetry, and two sole plates on which rest the feet of a user, carried pivotally on the support plate respectively on one side and the other of a plane of symmetry passing through the principal pivoting axis of the support plate, about respective auxiliary axes generally perpendicular to the upper surface of the support plate. Alternating pivotings of the sole plates about their respective axes, induced by the user, are accompanied by an alternating rocking of the support plate about the associated principal axis.

A skating apparatus, for facilitating replication of a skating stride, comprising a support surface with a pair of pivotable simulator arms. Each pivotable simulator arm supports a foot portion which is slidable along the pivotable simulator arm in a guide track. The foot portions are coupled to a resistance mechanism, via a chain, to provide resistance to the foot portions during a skating stride. The resistance mechanism includes a retraction device for retracting a chain during the return stroke of the foot portion.

A skier's exercise trainer has a base providing a front support and right and left rear lateral supports, with a transverse rear track portion extending laterally between the lateral supports. A pair of elongated ski plates are positioned side by side overlying the base with their front ends rockably and pivotally mounted near the front support of the base, and their rear ends spaced above the rear track. A truck assembly is rockably joined to the underside of the rear end of each ski plate, with an elongated tie bar pivotally connected to the underside of each truck, and a rolling support is rotatably secured to each truck in rolling contact with the rear track. A tension-carrying cable has a rear end connected to the central portion of the tie bar and extends forward under the ski plates between a pair of guide rollers rotatably mounted on the base in front of the tie bar. An adjustable tension spring assembly connects the front end of the base to the forward end of the tension-carrying cable. The device enables a user standing on the ski plates, by shifting his weight to apply pressure to the "uphill" ski, and changing "edge set" to establish reverse turn. The device thus simulates the motions of a downhill skier making a slalom-style run, with the spring assembly simulating the edging force produced by snow.
