Description

1 6 4 47

  The present invention relates to a ski comprising a core and a sliding surface coating, the core being covered on its upper face and on both.

  side faces with a plastic layer.

  The subject of the invention is the production of means for permanently protecting or producing the representation of a trademark, an acronym or a logo, etc. on the upper face of the ski, and / or likely to act on the sliding qualities of the ski

  and / or the exterior appearance of the ski.

  This object is achieved according to the invention in the case of a ski of the type mentioned above by the fact that a recess extending in the longitudinal direction of the ski has been provided in the upper face of the plastic layer. in which a plate, preferably made of plastic, is glued or housed. The latter may include an initials, a logo or similar element or else

protect this acronym.

  Thanks to the material used or thanks to its shape, this plate can also influence the sliding properties of the ski, so that it is possible in a simple way to make skis having a different appearance and / or different properties comprising a body of uniform skiing by incorporating by gluing, by injection of foam or the like various plates. According to another characteristic of the invention, the width of the plate is less than the width of the ski, at least on one

part of its length.

  The plate mentioned above may extend over the entire ski or over a part of the latter, the thickness of the plate being less, equal or

  greater than the depth of the hollow.

  The plate is preferably made in one

  transparent or translucent material.

  It’s useful to include trademarks,

  acronyms or logos or the like on the underside

the plate.

  Various other features of the invention

  moreover emerge from the detailed description which

follows.

  An embodiment of the object of the in-

  vention is represented, by way of nonlimiting example,

in the attached drawing.

  The single figure shows a cross-section

dirty of a ski according to the invention.

  The ski shown in the drawing comprises a part forming the body of the ski 1 and a plastic layer 2 produced as a molded element having the shape of a U. In the upper face of the plastic layer 2 is provided a recess 11 for inserting the plate 12. The part forming the body of the ski 1 is a prefabricated part composed for example of a core 3, an upper chord 4 and a respective lower chord, two steel edges 6 and 6 ′ located on the side of the sliding surface and having the shape of an L, of a sliding surface coating 7 and of an intermediate layer 8. The components of the part forming the ski body 1 are interconnected by gluing or a similar method, the lower layer 5 projecting vertically from both sides of the core 3 by the desired thickness of the lower ends of the plastic layer 2 produced as a molded element having the shape of 'a U. The surfac sliding glide 7 preferably produced as a coating of plastic material fills in a known manner the space between the vertical uprights of the edges 6, 6 ′, while the space between the horizontal uprights is filled by the intermediate layer 8 also produced preferably in plastic. In the present case, the core is made of a material, which attaches securely to the plastic layer 2 in at least the region of the layers which are in contact with the molded element 2 in the shape of a U. During manufacture skiing, the plastic layer 2 will preferably be made by a

  reactive injection molding process.

  When using a coating material & polymethane base it is useful to make the steel edges and the sliding surface, that is to say at least the elements of the part forming the body of the ski which constitute the outer face of the latter in a material on which the coating material does not adhere, for example polyethylene or steel, which has the advantage that after the manufacture of the molded element 2 in the form of U the coating material overflowing if necessary on the outer lateral faces of the steel edges 6, 6 ′ or on the coating of the sliding surface 7 can be wiped off easily so that it is not necessary to mechanically clean with a tool the surface of the ski. The outer face of the U-shaped molded element is absolutely smooth without treatment, wear-resistant and tenacious to impact, there is no splintering and its exact dimensions are preserved. The hollow 11 provided in the upper face of the plastic layer 2 can also be produced by demolding according to the process of

  reactive injection or milling molding.

  As shown in the figure, in the hollow 11 thus produced is glued or inserted a plate 12, for example in a transparent material, preferably a plastic material, the thickness of the plate 12 being equal, less or greater than the depth of the hollow 11. The plate 12 glued in the hollow 11 exceeds in height - in the case where the thickness of the latter is greater than the depth of the hollow - the surface of the plastic layer 2 produced as a molded element having the shape of a U, which has the advantage that during bonding regular pressure can be exerted on the whole of the upper face of the plastic layer 2, so that no faults occur molding in the bonding joint. The underside of the plate 12, insofar as it is made of a transparent or translucent material, may include the name of the manufacturer, the initials or the logo or the like, the affixing preferably taking place by printing, by gluing or of another

  way. Thus, such brands, acronyms, or company logos

  sockets are better protected from wear or damage

  ration, especially when the skis are crossed, than in the case of usual arrangements directly on the upper face or the sliding surface of the ski. Such an arrangement under the plate 12 therefore allows a three-dimensional configuration of letters, writings, drawings (logos) etc. Since the width of the plate 12 is less than the width of the plastic layer 2, the edges of the plate 12 are protected, which is particularly important when the skis are crossed. Therefore,

  the plate 12 itself, can contribute to the external appearance

  laughing at the ski, for example, by coloring or modeling.

  The plate 12 can be produced on the entire ski or on a part of the ski, or else several plates 12 can be arranged in succession or can be superimposed. They can also be arranged

  way apart in the longitudinal direction.

  The hollow 11 described above and the plate 12 housed therein can be made in any kind of ski using techniques of

simple production.

  The ski according to the invention has an extraordinarily high protection against wear. He can be

manufactured at a low cost.

  Of course, various modifications to the construction and technology can be made within the scope of the invention. Thus, there is the possibility of adapting the embodiment of the recess 11, as well as

  from plate 12 to technical production requirements

  tion. In addition, the thickness of the plate 12 can be less than the depth of the recess 11. Furthermore, there is the possibility of using the plate 12 to act on the hardness or on other characteristics of the ski. For this purpose can also be used plates in

  metal, wood or other materials.

  If the ski was provided with bumps or hollows, the plate intended to be housed therein can be adapted to such three-dimensional configurations. The same is also valid for the ski tip, for the raised ski heel, for a deflector, in relief or in the form of recesses, such as letters, or

trademark, or similar.
