摘要:
This invention provides a pair of downhill snow skis having deep side cuts which allow greater maneuverability and safety, particularly on steep slopes. Each ski is provided with two cutting edges on each side, as contrasted to one on each side in ordinary skis. The lower edge, on the bottom of the ski, is active when the angle between the ski and the slope ranges from near zero up to 52 degrees; the upper edge, near the top of the ski, is active at angles greater than 52 degrees. These edges provide ability to execute true carved turns of about one-tenth to one quarter the radii of turns executed by ordinary skis (about 20 to 45 feet as compared to about 200 feet).
摘要:
A process for manufacturing a ski, and a ski manufactured by the process. The process according to the invention includes at least the following steps for manufacturing a ski whose body includes a core covered with a shell, wherein the shell is a composite sub-assembly: positioning the sub-assembly adjacent the cavity of a mold; positioning the core adjacent the shell; and exerting a force against the core to thereby force the shell within the mold cavity. In a preferred embodiment, the sub-assembly includes at least one layer of a filling material, preferably a thermoplastic material, which is caused to soften and flow under predetermined temperature and pressure conditions. In a modified embodiment, the mold cavity includes a depression or a projection on, for example, its lower surface which thereby produces a corresponding projection or depression, respectively, on the upper surface of the ski. By virtue of such a molding process, a variety of skis having various cross-sections and compositions are possible. For example, the upper edges of the skis thus manufactured can be reinforced with elements embedded in the filling material of which the edges can be made. Likewise, shock-absorbing material can be embedded within the aforementioned projections which can be made on the upper surface of the ski.

A ski and ski-binding combination. The ski has several holes for receiving therein fastening screws for the selective fastening of ski-binding elements arranged in the ski in the binding-installation area. The holes are covered, however, are marked to the outside by markings. The arrangement of holes for the ski-binding elements is adjusted to the length of the ski and chosen such that the ski bindings are suited to receive only a limited number of successive ski-boot sizes.

The ski comprises a central core covered by a metal blade. Bearing layers are arranged above and below the core and the blade covering it. Edges are provided laterally adjacent to a sole, with portions extending above the sole. Two side elements are arranged on either side of the core and the bearing elements and above the edges. The side elements are constituted by laminates comprising a reinforcing blade, e.g. of aluminum or aluminum alloy, whose upper end appears at the upper face of the ski and acts as an upper edge.

An alpine ski with flexible impact absorbing edges and elastomeric sidewalls is provided to enable the bottom edges to follow the contour of the ground by moving therealong and absorbing the unevenness of the ground.
摘要:
A running surface or coating material, or coating for a ski, for variable snow conditions, in particular for use in cross-country or long distance skiing, is mounted in the central region of the running surface of the ski as an ascending aid. The coating consists of a soft elastically behaving substance and a harder particle component. Part of the harder particles are so disposed that they project from the bottom surface of the ski. This is accomplished by grinding the surface of the ski bottom coating plate means to be the bottom surface, in such manner that a hairy cover is produced on the ground surface. The projecting particles of the hairy cover are affixed by their roots in the elastically behaving substance.

The span of the ski is provided with a horizontal slit passing through the span and dividing it into an upper part and a lower part, the lower part being more easily bendable in vertical direction than the upper part. For influence of the front sole part of the ski boot is arranged a pressure member, movable in vertical direction, which member passes through upper part and is fastened to or in any other way arranged to engage with the lower part of the span.
摘要:
A running-surface plastics coating for skis comprises a running surface forming a climbing aid and provided with a multiplicity of tongues (4) which are aligned in the longitudinal direction of the ski and terminate towards the rear end of the ski in pointed ends capable of being bent upwards to provide a means for reducing the sliding resistance in the running direction without impairing the climbing aid. The tongues (4) are defined by cuts (2a, 2b) provided in the running-surface coating (1), at an acute angle with each other, the cuts extending from the plane running surface toward the underside of the ski and including an acute angle with that plane so that the inwardly and upwardly slanted side edge surfaces of each tongue are rhomboidal and diverge with respect to each other from the tip of that tongue.
