A ski is provided with an internal support structure configured to ensure adequate strength for the ski. The internal support structure is formed to define at least one internal cavity. An outer shell surrounds the internal cavity and the internal support structure and defines the exterior of the ski. The internal support structure may be formed from opposed halves assembled to one another. The internal support structure may include a plurality of outwardly extending positioning legs formed unitarily therewith for positioning the internal support structure within an injection mold cavity. The ski may further be provided with metal edges snapped into grooves formed on portions of the bottom surface adjacent the sides.

A ballet ski is provided for achieving enhanced stability when a skier is stationary or moving slowly. The bottom surface of the ski has a planar elliptical portion centrally under the foot of the skier. Remaining portions of the bottom surface are convex from front to rear and convex from side to side. Thus, a skier can easily roll from the planar ellipse and into the curved portion to carry out selected ballet maneuvers. Preferably, the ski is formed from separate top and bottom components configured to form air pockets that reduce the weight of the ski. The ski may also include chamfers near the rear binding to enable a brake to rotate into the snow. Additionally, hook receiving apertures may be formed through the rear end of the ski. A pair of the skis may then be used with straps having hooks engageable in the apertures for conveniently suspending the skis in a carrying position.

This ski comprises longitudinal reinforcing elements, each bearing on one edge, and forming the sides of the ski, at least one of them extending over a part of the height of this ski, and a shell forming the upper face and a part of at least one of the lateral walls of the ski, and the longitudinal borders of which rest and are fixed on the upper face of the sides, the respective heights of a side and of the shell on at least one of the lateral parts of the ski varying in the same proportions over the length of the ski.

The present invention relates to ski having a tip portion, a tail portion and a waist portion between the tip portion and the tail portion. In accordance with the present invention, the ski has a wider tip and tail than do conventional skis. This widening of tip and tail are coupled with an exaggerated "side cut" or curvature of at least in the inside edge of the ski. A ski according the present invention has an exaggerated tip between 1.5 to 2.25 times the narrowest point of the waist and an exaggerated tail with a ratio of 1.05 to 2.14 times the narrowest point of the waist.
摘要:
Ski shaped like an elongated beam, comprising a lower slide face bounded laterally by two lower edges, an upper face bounded laterally by two upper edges, and two lateral faces, the ski being constituted by a central part extended toward the front by a front part ending, at its front end, by the tip and extended toward the rear by a rear part ending, at its rear end, in the heel-piece. The front part is constituted by a front section connected to the central part by a front intermediate connection section, while this rear part is formed by a rear section connected to the central part by a rear intermediate connection section. The two upper edges of the upper surface are parallel in the central part, while one of the two front or rear section is such that, in this area, first, the lateral faces are inclined so as to converge upward, and second, the upper surface is narrower than it is in the central part and has a uniform width.
摘要:
A ski with a core between a lower and upper strip layer over the entire length of the ski, with attached portions of lightweight material in front of and behind the ski boot support zone. The attached portions are glued to the upper strip layer. The ski is encased by a molded integral sheath of plastic material.

This snow ski, the sides of which have an inclination which is variable in relation to the plane of the sole of the ski, at different points along its length, and are constituted by curved convex or concave lines, in which the profiles of the sides are of variable curvature according to the cross-section in question of the ski.A procedure for manufacturing this ski consists, starting from a rough ski, in carrying out the machining of the lateral parts of the ski with the aid of a rotary tool with an axis perpendicular to the plane of the upper surface of the ski, the active surface of which is generated by a continuous monotonic curve, by carrying out a relative movement of the tool and of the ski simultaneously, in the direction of the length of the ski, in the direction of the width of the ski and in a direction perpendicular to the plane of the upper surface of the ski.
摘要:
A ski comprises a longitudinally extending body having a central region interposed between anterior and posterior segments. The body has a lower sliding surface whose width is defined by a pair of opposed lower edges connected to two lateral side surfaces that are inclined relative to the lower sliding surface. An upper surface is connected to the laterally side surfaces and has a width defined by opposed lateral edges which converge towards the front of the ski.
摘要:
The ski has a box-shaped, substantially rigid middle portion, a front portion and a rear portion which can be easily bent and are elastic and resilient in an upward direction and are capable of torsion in the longitudinal axis. Balancing elements formed of soft, but permanently elastic material, are inserted at the transition of the middle portion to the rear portion in the direction of the rear end of the ski, on the one hand, and/or at the transition of the middle portion to the front portion in the direction of the tip of the ski on the other hand. The balancing elements are inserted in the ski so as to be either not detachable or fixed, but detachable and exchangeable.
