Definitions

  • the present invention relates to manufacturing of skis and snowboards, and especially to providing special effects by the skis or snowboards, like dampening vibrations, achieving desired stiffness of skis or snowboards and similar.
  • the invention relates to both, skis and snowboards.
  • a ski is a flattened, relatively narrow and elongated product, which is at the one of its ends slightly bent from the ground away
  • a snowboard is a flat, relativelly wide and elongated product, which is slightly bent from the ground away on its both ends.
  • On the bottom side of such ski or snowboard there is an appropriate sliding surface, by means of which a smoothly sliding of the ski or snowboard along appropriate surface covered by snow or ice is enabled, and which is generally provided or sidely ended by appropriate ski edges, extending longitudinally on the both sides of the ski or snowboard.
  • the desired elements are foreseen on desired locations, which serve for establishing a required interconnection thereof with appropriate shoes.
  • the main purpose of the present invention is to create a ski or a snowboard, by which at the one hand the existing properties related to sliding, attaching each desired ski binding or snowboard binding and maintaining the existing shape including measures should be kept, and on the other hand a wide possibility of predetermining each desired mechanical or physical features should be given, especially stiffness, elasticity, efficiency in course of dampening vibrations or similar, and also of achieving various visual effects on the surface of the ski or snowboard as a commercial product.
  • a plurality of solutions is already available in field of skis, which relate either to dampening vibrations or controlling stiffness of a ski.
  • vibrations may be dampened by adding an elastic band onto the top surface of the ski, while between the said band and the ski an elastomeric layer is incorporated.
  • stiffness may be determined by means of longitudinal reinforcing ribs available on the top surface of a ski. Whenever inside of the said ribs an elastomeric layer is available, such construction may also enable dampening of vibrations. Consequently, such measures may also result achieving a desired pressure onto the ski edges along particular areas of the ski, while all these features have an important influence with respect to general performances of the ski, especially by turning.
  • snowboards consist of two layers, namely of a sliding layer with the belonging edges, as well as of a covering layer.
  • the sliding layer serves for ensuring desired sliding properties, while the purpose of the said covering layer is to ensure a required stiffness and elasticity as well as possibility of mounting a shoe binding, and moreover also achieving an attractive visual appearance of the snowboard as a commercial product.
  • Thickness of the said sliding layer both in the longitudinal direction and also in the transversal direction of the snowboard - excluding possible grooves or similar modifications of quite local nature - remains practically unchanged, by which the sliding layer and the covering layer are interconnected by means of adhesive.
  • the thickness of the covering layer remains the same both in the longitudinal as well as in the transversal direction, which means that the covering layer needs to be relatively thick, since the required stiffness and elasticity have to be ensured, by which the complete covering layer must also consist of the same single material.
  • the bending stresses, to which the snowboard is exposed are the highest in the middle area of the snowboard, and thickness of the covering layer outside of the said area is always too high without any serious reason, which means, that the weight and herewith the manufacturing expenses are also essentially too high. It may also happen, that certain materials are acceptable with respect to the stiffness, but are unable to dampen vibrations or are not acceptable with respect to adhesiveness as required by applying various colorants or other coatings, which are necessary for obtaining attractive visual appearance, which is no doubt also very important from quite commercial aspects. In this connection it should be noted, that the overall surface of the covering layer is relativelly large, so that the said requirement related to ensuring a required adhesiveness is very important.
  • the thickness of the covering layer is varried in the longitudinal direction and/or in the transversal direction, which however requires strong support of essentially more sophisticated technology, which results essentially higher costs on the other side.
  • One of such variations is known e.g. from US 6,290,249 B 1.
  • a board is described without any ski-edges, by which appropriate consistence in each desired direction is achieved by means of plurality of grooves extending in the longitudinal direction.
  • the covering layer of such board has a concave shape and is provided by a thickened rand, which extends along the complete circumference thereof.
  • a preferred embodiment of the snowboard according to the invention comprises also an intermediate element, which is at least partially visible from outside and is conceived as an intermediate layer arranged between the sliding layer and the covering layer and/or as an insert and/or a longitudinal segment incorporated within the said covering layer along a desired area in the longitudinal direction of the snowboard.
  • the said intermediate element which is visible from outside, may also be conceived as an intermediate layer placed between the sliding layer and a covering layer, extending preferrably over the complete width and over at least major part of the lenght of the sbnowboard, and being preferrably adapted for dampening vibrations and/or for achieving a desired stiffness and/or elasticity.
  • a snowboard according to the invention comprises an intermediate element, which is at least partially visible from outside and is conceived as a longitudinal segment being incorporated within the covering layer, and preferrably adapted for achievement of a desired stiffness and/or elasticity and/or, when desired, also adhesiveness and/or rigidity.
  • the intermediate element which is at leeast partially visible from outside, may be conceived as an insert being incorporated within the covering layer and extending over at least a part of its length and/or a part of its width and preferrably serving for achievement of desired physical or mechanical properties in the area of incorporating the insert, whichare different from the properties of the sliding layer and/or covering layer of the snowboard.
  • Preferrable embodiment of the ski according to the invention is characterized by comprising an intermediate element on each side, which is at least partially visible from outside and is formed of at last two longitudinal segments, which consist of desired materials and extend in the longitudinal direction over the a least essentially major part of the length of the ski, by which the said element is arranged above each belonging ski edge as well as the sliding layer, and below the covering layer and adjacent thereto.
  • Another embodiment of the ski comprises on each side an intermediate element, which is at least partially visible from outside and is formed of at least two longutinal segments made of different materials, as well as of at least one insert, which is visible from outside and consists of a material, which is different as the material of at least one of the said segments.
  • the said element extends in the longitudinal direction over at least major part of the length and is arranged above the belonging ski edge as well as the sliding layer, adjacent to the core and below the covering layer adjacent thereto.
  • Still another embodiment of the ski comprises on each side an intermediate element, which is at least partially visible from outside and is formed of at least one longutinal segment as well as of at least one insert consisting of different material as the segments.
  • the said element extends in the longitudinal direction over at least major part of the length and is arranged above the belonging ski edge as well as the sliding layer, adjacent to the core and below the covering layer adjacent thereto.

Between a sliding layer 1, which enables a required sliding capability, and a covering layer 2, which ensures sufficient strenghtness for obtaining a required bending and/or torsion rigidity or elasticity of the snowboard, there is an intermediate element 3, which is by this particular embodiment available in a form of an intermediate layer 31, and consists of a material, which is capable to dampen shocks and vibration, to which the snowboard is exposed during the use. Strenghtness of materials, which may serve for dampening vibrations, is namely relatively pure, so that the covering layer 2 may not consist of these materials, whenever it is in function of a load-bearing layer.
  • the covering layer 2 may consist of a light and non-expensive material having excellent adherence against colouring coatings, while the intermediate layer 31 may consist of a stiff and elastic material with insufficient adhesiveness with respect to the said coatings.

  • each insert 33 serves either for the purpose of locally increasing hardness of the snowboard, or also for locally improving of adhesiveness to various coatings e.g. of colours, adhesives etc. applied thereto.
  • FIGs. 8 to 14 three embodiments of a ski are shown.
  • the first embodiment relates to an assembled, so-called “sandwich" ski, which is shown in Figs. 8 to 10.

  • several reinforcing layers may be aligned either between the sliding layer 1 and the core 4 or/and between the core 4 and the covering layer 1.
  • a single intermediate element 3 is foreseen beyond the belonging ski edge 11, 12 and above the sliding layer 1, which extends thereby in the longitudinal direction of the ski and is moreover placed adjacent to the said core 4 as well as below the covering layer 2 or adjacent to it, if appropriate.
  • Such an intermediate element 3 is formed by at least two longitudinal segments 32 consisting of various materials characterized by various physical and mechanical properties.

  • Essential benefits may be obtained by using such intermediate element 3 and segments 32, since even by unchanged shape and dimensions of the ski and by using the same core 4, certain features of the products manufactured in a serial production may be be essentially varied, like the pressure on the edges 11 , 12 along the front part or rear part of the ski, or similar.
  • the ski according to Figs 11 to 13 also consists of a sliding layer 1, adjacent to which there is a ski edge 11, 12 arranged on each side of the ski, and moreover also of the core 4, which is placed above the sliding layer 1 and which is in this particular embodiment available as an amorphous, hardened foam on the basis of polyurethane.
