Abstract:
A shell for sports shoes, particularly for Telemark skiing, which comprises a sole and a lateral surface which surrounds the foot of the user. A frame is rigidly coupled internally to the shell and has a foot resting surface and a toe cup which partially extends over the upper metatarsal region. On the resting surface and on the toe cup there are, respectively, at least one first transverse opening, arranged below the metatarsal region, and at least one second transverse opening, which lies above the metatarsal region. A transverse bridge, arranged in the region that lies to the rear of the metatarsus, is thus formed at the toe cup. The resulting shell is therefore highly flexible but torsionally rigid, making it easier for the user to ski.
Abstract:
There are two assemblies in the binding, a harness assembly and an attachment assembly. The harness assembly attaches to a ski boot and has a toe fitting which fits over the toe of the boot and has a flat metal plate contacting the toe portion of the sole of the boot. Four sharp pointed posts extend downward from the plate. Each post has a groove near its base, perpendicular to the axis of the post. The attachment assembly attaches to the ski and has latch bars which engage the grooves in the posts to attach the attachment assembly and ski to the harness and ski boot. One latch bar is spring loaded toward the other and as the posts are inserted onto the attachment assembly the spring loaded bar is moved to allow the posts to pass. When the posts are fully inserted the spring loaded bar moves to capture the posts. There is a lever operated cam at the forward end of the attachment assembly which is used to separate the latch bars to enable detaching the ski from the harness. With the ski and attachment assembly removed, the sharp posts serve the crampon function.
Abstract:
A skiboard system is provided. The system includes a skiboard and left and right loose heel binding secured to the skiboard. The skiboard has a longitudinal axis, a central portion and an upward curving front shovel area. The central portion includes side edges and a central waist. The side edges have concave curvatures of radius and extend between front and rear ends of the central portion so that the concave curvatures of the side edges form the central waist. The central portion further includes a longitudinal camber, which elevates the waist. The upward curving front shovel area has a front tip and is formed by the front end of the central portion. The left and right loose heel bindings are secured to the central portion substantially parallel to each other on opposite sides of the waist at an acute angle less than 35 degrees from the longitudinal axis. Furthermore, the bindings are angled to the right of the longitudinal axis when the left binding is in front of the waist and the bindings are angled to the left of the longitudinal axis when said right binding is secured in front of the waist.
Abstract:
A release binding for skis is usable both for touring or cross-country and downhill runs. It comprises a touring plate which has a front end portion which is pivotally mounted at its front end for movement about a horizontal axis which extends transverse to the longitudinal axis of the ski. The touring plate also includes a rear portion which is connected through a length adjustment mechanism to a heel holder portion. A sole holder is connected to the front end of the touring plate and it carries a blocking part which is seated on the touring plate and it includes an upstanding part adjacent its front end which is disposed above the horizontal pivotal axis of the touring plate which bears against a blocking element which is mounted on the ski ahead of the touring plate and is biased by a spring against the blocking part. When the touring plate is pivoted upwardly during a cross-country run, the blocking element is displaced rearwardly against the biasing force of the spring.
Abstract:
The invention relates to a ski binding (1) for fastening a ski boot, comprising a front retainer (2); a rear retainer (3); a tensioning mechanism (20) acting between the front and the rear retainer whereby the ski boot can be clamped between the front (2) and the rear (3) retainer in such a way as to allow the heel to be lifted freely; a front sole support device (6) arranged at or by the front retainer (2), the front sole support device being pivotal about the horizontal transverse axis (7) relative to the front retainer (2); and a locking element (8) adapted to fix the front sole support device (6); wherein the locking element (8) is adapted to lift the front sole support device (6) into contact with the front part of the ski boot such that the front sole support device (6) is fixed between the locking element (8) and the front part of the ski boot.
Abstract:
Ski binding system, comprising a support structure (2) which is fastened to a ski (12) and carries a binding (3) for footwear and which is able to assume a first operating configuration, where it is rigidly fastened to the ski, parallel thereto, and a second operating configuration, where it is hinged on the ski about a transverse axis of rotation situated behind the footwear and is able to pivot in a longitudinal plane at right angles to the ski. The front end of the support structure (2) is connected to the ski by means of a kinematic mechanism (14) forming a system for guiding the raising movement of the structure, the binding system being provided with a locking mechanism (20) which can be operated so as to assume a locked position, where the support structure (2) is rigidly fastened to the ski (12), and a released position, where the support structure (2) is able to pivot relative to the ski (12). The locking mechanism comprises an actuating element (23; 33; 43), which is mounted movably on the support structure (2) and associated with a resilient recall member (27; 37; 47), and a base plate (24), which is fixed to the ski and carries an engaging formation (28) able to be engaged by a locking pin (22; 32; 42) arranged transversely with respect to the longitudinal direction of the ski (12) and mounted on said actuating element (23; 33; 43). In the locked position the locking pin is biased against the engaging formation by the resilient recall member (27; 37; 47) and can be disengaged therefrom by means of displacement of the actuating member (23; 33; 43) against the action of the resilient recall member.
Abstract:
A binding of the clap ski type for a ski or skate (1), comprising a base plate (10) attached during use on a ski or skate, a hinge part (2) attached during use on the base plate, a support (8) attached at a distance therebehind on the base plate and a frame (4), attached in operation to the hinge part (2) by means of a hinge pin (3) and pivotable between a closed position and an open position, which frame is provided with front (5) and rear (6) fastening means for a shoe (7) of an athlete, wherein return means are provided which can return the pivotable frame (4) from an open position into the closed position, which return means comprise at least one or more first permanent magnets (62) which are provided on the part of the pivotable frame (4) located before the hinge pin (3) and which cooperate with one or more second permanent magnets (65), which are provided on the hinge part (2) opposite the first permanent magnets (62), while the first (62) and second (65) permanent magnets repel each other.
Abstract:

Abstract:
Snow skis (100, 200) having asymmetrical edges to make turning easier while telemark or alpine skiing. Each ski (100, 200) has concave, curved lateral edges (110, 120, 210, 220). These lateral edges are asymmetrical, in that the medial edge (120, 210) of each ski (100, 200) is substantially longer than its outer edge (110, 220). In addition, the point of maximum side cut (115, 225) on the outer edge (110, 220) is adjacent to the toe area of the skier's boot (160, 260), while the point of maximum side cut (125, 215) on the medial edge (120, 210) is adjacent to the middle of the ski boot (160, 260) to facilitate easier turns while telemark skiing.
