Definitions

  • the invention relates to a support surface sold by the meter for the production of climbing skins with a velor side and an opposite rear side, with bristle-like poles protruding on the velor side, which are configured individually or as a bundle and parallel to one another at a predetermined angle a to the surface orientation of the support surface are aligned.
  • the invention also relates to a climbing skin for mounting on the underside of skis or other snow sports equipment as a climbing aid or as a kickback aid.
  • Climbing skins also known as ski skins
  • ski skins are used as climbing aids or rebound aids when walking uphill on the snow by being mounted on the undersides of skis, split snowboards, cross-country skis, sleds or other snow sports equipment. They should have as little resistance as possible when gliding, e.g. when a ski with a skin is pushed forward.
  • the poles pointing backwards should prevent the snow sports equipment from slipping backwards, on the one hand in steep terrain uphill, on the other hand when recoiling, for example when cross-country skiing or climbing.
  • the poles that form the restraint aids are the hairs on natural skins, which grow parallel to each other into the leather.
  • the poles are attached to a carrier surface, for example according to the scale principle, as plates, as is known from EP3437701.
  • EP 2167204 describes a method of anchoring the poles in a layer of glue by flocking.
  • velor-like fabrics can be produced in a weaving process and their fibers can be fixed in the desired layers. For this purpose, they are reshaped resp. folded, for example under the influence of heat. The fibers are finished by impregnation to reduce water vapor penetration.
  • a climbing skin is known from DE 4309488 A1 in which the skin layer extends only in the edge regions of the climbing skin in order to reduce the frictional resistance when sliding.
  • the object of the present invention is to describe a support surface for creating climbing skins with a velor side which slides better than conventional support surfaces for this purpose without having to accept losses in grip when slipping backwards.
  • Another task is to describe lighter such carrier surfaces. In preferred configurations, they should also be more flexible when rolled up and take up less space.
  • the freedom of design should preferably be increased in order to improve the recognition of the manufacturer.
  • the carrier surface should be able to be used economically over the entire width of the piece of goods in order to cut out climbing skins.
  • the invention is achieved in that on the velor side, a partial area of 10 to 50% of the total support area, preferably about 15 to 35%, is designed, which is free of poles or in which the poles in their free-standing length are at least 1 /3 are shorter than the poles outside of this partial area.
  • This free-standing length is called the pole length.
  • the sub-area is distributed on the support surface in small units in relation to the size of a climbing skin. This eliminates the need to align the climbing skin on the backing surface after the partial area.
  • the partial area can be divided into a large number of individual areas or can be continuous.
  • the climbing skin according to the invention is manufactured in one piece from the supporting surface as a piece of goods and does not have to be assembled from individual strips of different types.
  • This has the advantage that climbing skins can be cut out of the piece goods in any desired contours and dimensions without having to assemble different fur-covered parts with non-fur parts, for example by sewing or gluing.
  • all climbing skins cut out of the support surface according to the invention have the same qualities, regardless of whether they are cut for a narrow cross-country ski or for a wide split snowboard. Therefore, the entire width of the carrier surface can be optimally utilized.
  • the width of the climbing skins can range from a few centimeters for cross-country skis or sleds to well over 10 cm for split snowboards.
  • the pole-free or pole-shortened sub-area consists of connected or non-connected areas that are distributed over the support area in such small units that they appear homogeneous in a climbing skin area.
  • the proportion of the partial surface to the total support surface of a climbing skin is therefore not dependent on the selected position on the support surface from which the climbing skin was cut out. Depending on this position, the deviation is hardly more than 3%, at most 5%.
  • climbing skins can be produced with practically the same qualities, whereby the entire width of the yard goods can be used well. Alignment to the partial area is not necessary.
  • Such a small structure can be achieved, for example, by the smallest distance from any point from the carrier surface to the edge of the next sub-area being at most 6 mm, preferably at most 4 mm, and/or by the sub-area consisting of parallel strips which are at most 4 mm, preferably at most 2 mm wide. Such uniformity in the distribution of the sub-area ensures the scope for any desired cuts.
  • the partial area should always consist of one or a large number of connected areas. Only a thinner distribution of the poles, as it were, does not lead to partial areas that are free of poles. It has been shown that such support surfaces have a lower hold proportional to the thinning, while the support surfaces according to the invention approximately have the same hold as carrier surfaces which, with the same coverage density of poles, do not have any vacancies. This has to do with the fact that a pole that lacks a lateral neighbor when backed up in snow can spread laterally into the void and achieve good locking action while being supported by the neighbors on the other sides. Therefore, a large number of parallel stiffeners running in the direction of travel from empty spaces or shortened poles particularly well.
  • the strips can also be inclined by up to 45° to the direction of travel, which is defined by the projection of the direction of the pole inclination, and can form a zigzag shape or a checkered pattern, for example. Lettering with a narrow font thickness or ornaments are also conceivable. At most, minor losses are accepted in order to form a desired design.
  • An overlay of, for example, parallel lines of about 25% and widely offset minor design elements is visually appealing while ensuring a good grip, with at most minor sacrifices.
  • the erection angle ⁇ of the poles is inclined, for example, between 10 and 60° to the surface alignment of the support surface, preferably between 15 and 45°.
  • a typical pole length is about 2-6 mm, preferably 3-5 mm.
  • the poles are always aligned in such a way that they are aligned at an obtuse angle to the subsequent direction of travel, in particular at an angle between 120 and 170°. Thus, the pole tips point against the direction of travel.
  • the sliding properties of the support surface are improved by the design according to the invention.
  • the sliding resistance of climbing skins made from it is reduced by the smaller contact surface of the climbing skin, namely by reducing the number of poles that touch the snow when gliding. Surprisingly, this does not reduce the grip, which is supposed to prevent slipping backwards.
  • the 50-90%, preferably 65-85%, of the remaining poles can properly assume the required adhesion. If the poles are shortened, their retaining force also remains almost unrestricted. Reducing the number of poles or shortening the pole lengths in the sub-areas also reduces the weight per unit area and the volume of the climbing skin and at the same time increases its flexibility when it is rolled up.
  • the free sub-areas can also be designed as geometric patterns. Spikes or arrow patterns are just as possible as the design of patterns into which logos can be integrated, for example. Since the individual poles resp. Bundles of poles can be of any color, any graphic design is possible. The freedom of design is further expanded by the free arrangement of the sub-areas. For example, logos can be separated from the background by the partial areas.
  • Another possibility for producing the carrier surfaces according to the invention is to produce a knitted fabric from knitted fabric, for example with a Raschei warp knitting machine.
  • a third possibility for producing the carrier surfaces according to the invention consists in weaving a fabric surface from warp and weft threads into which the bristle-like poles protruding on the velor side are woven.
  • dobby velor machines or jacquard velor machines are used.
  • Pile chains running in the direction of the warp are used to form pile tufts, which are cut off after weaving and form the piles protruding on one side with the specified pile length.
  • the poles are given the desired angle a by a tensioning chain.
  • the poles can be designed as covered or uncovered monofilaments, multifilaments or fiber yarns. Each tuft is visible as a tuft on the back of the backing sheet.
  • Such fabric surfaces can be divided into regular grid positions, of which according to the invention 50-90% (preferably 65-85%) are occupied by poles and correspondingly 10 to 50% (preferably 15-35%) are unoccupied by poles.
  • the unoccupied grid positions lie in a row, preferably aligned in the warp direction.
  • the poles can each completely occupy three rows of grid locations, while every fourth row of grid locations is unoccupied by poles. Or two out of three or four out of five rows of the grid positions can be fully occupied, the others are free.
  • the weight is correspondingly saved by omitting individual pile warps. If every fifth pile chain is left out, 20% of the pile chain weight is saved, if every fourth pile chain is left out 25% and if every third pile chain is left out 33%. Every fourth pile warp is preferably left out.
  • the pile warps can also run in places in the fabric surface and thus not form any pile tufts in predetermined grids.
  • the pile warps can also form a pile nub offset by a grid in their transverse position, which means that any pattern can be created.
  • the support surface can also be completely occupied by poles, with the pole length of the poles being reduced by at least one third in the sub-surfaces, for example by milling, shearing or etching. Poles can also be completely cut off or otherwise shortened, reducing pole length to zero.
  • the backing surface can be provided with an adhesive on its back to reduce slipping on the snow sports equipment and/or to fix the poles firmly to the backing surface.
  • only synthetic or vegetable raw materials are used for the production of the carrier surfaces according to the invention and no animal products. This creates purely vegan carrier surfaces.
  • Climbing skins for mounting on the underside of skis, split snowboards, cross-country skis, sleds or other snow sports equipment can be made from all the carrier surfaces mentioned here will. This these as a climbing aid and / or as a recoil aid, especially in cross-country skis or sledges.
