SI21407A - Decorated ski or snowboard as well as procedure for manufacturing such product - Google Patents

Abstract

The decorated ski or snowboard consists of at least one sliding layer (1) with corresponding edges (11, 12), a lower supporting layer (3) as well as a core (2), and apart from that also of at least one upper supporting layer (4) located above the aforementioned (1, 11, 12, 2, 3) components in the top ski or snowboard area. The aforementioned layer (4) is designed as an at least partially light permeable supporting layer (4) from reinforced duroplastic material and is decorated at least on its upper/external surface (41) and/or lower surface (420). This way it is possible to provide a mechanical damage and environmental impact safe decoration of the upper ski or snowboard surface layer without the need of applying the currently used top layer from thermoplastic material. This way the weight of the ski or snowboard can be considerably reduced, and additionally its manufacture leads to lower production cost. The invention deals with the construction concept of the ski or snowboard itself as well as the process of its manufacture.

Description

Decorated ski or. snowboard and the process of making this kind of product

The invention falls within the field of manufacture and skis and snowboards, in particular the decoration of such products. The term ski defines a flat, relatively narrow, elongated and slightly curved product at one end and a curved product at one end, while the term snowboard, hereinafter referred to as a board, is relatively wide, elongated and slightly rounded at the ends. from the base a curved product.

Starting from the ski or the ski. a snowboard consisting of at least a sliding lining with associated edges, further from at least one lower carrier layer above said sliding surface, further from a core above said carrier layer, as well as at least one upper carrier layer located above said core, and in which at least in certain areas, except for the said sliding edging with edges, an outwardly visible decorative pattern is provided, the invention is based on the problem of how to retain the possibility of realization against mechanical damage and the effects of the environment protected externally visible decorations of the ski or ski board, while at the same time facilitating the structural design in terms of reducing the number of layers required, and thus the height of the cross-section of the ski / board, thus making the ski or ski. the ski board can be much easier and its construction is associated with lower costs. The problem concerns both the design of the ski or the ski. snowboards as well as the process of making them.

-2The problem of snowboard decoration is generally dealt with in JP 03193072 A (Application No. 01334276; NIPPON MINNING CO), with the decoration of the lower surface, namely the so-called sliding cover. However, the solution under consideration concerns only the possibility of applying decorative patterns to the particular materials that make up the sliding lining of the board. Sublimation dyeing of the sliding surface is proposed based on fluorocarbon resin, which, on the one hand, provides excellent sliding of said surface and, on the other hand, the necessary durability of decoration.

The term sublimation dyeing or sublimation, as used in the art, means dyeing with sublimation dye. This way of painting the skis was, for example. also described in EP 0 774 365 BI (Salomon S.A.). The dye is deposited in the form of solids on a paper carrier, from which it sublimates under the influence of temperature and pressure, and penetrates or steam in the form of steam. diffuses into the surface of the product being painted. Unlike paint coatings, which form a layer of paint on the surface of a colored object, sublimation is a dye that penetrates the surface of each colored object. Sublimation dyeing is distinguished by the possibility of dry application of the decoration to various plastic carriers, while at the same time being clean, fast and easy to release harmful substances into the environment.

In order to provide a fine multicolor pattern and metallic luster to the snowboard on the upper surface, it is further proposed in JP 09240131 A (Application No. 08052095; ΥΑΜΑΗΑ CORP.) To sublimate the upper lining to either perform a multicolour pattern, dispersing metallic particles into the dye sublimation dye, or the upper coating being made of transparent resin and a layer of metal foil placed underneath. Optionally, a metal foil is placed over the supporting layers and the sliding liner, and in each case a relatively thick top liner, which is required for decoration as well as for protection of the decoration against external influences (shocks, abrasions, moisture, frost and the like). The need for the presence of this top lining is associated with an insignificant cost, but also contributes to a significant increase in the weight of the board, the size of which can be estimated at least 10 to 20% by weight, and in most cases about 15% of the total weight of the board.

Further, DE 38 03 483 Al (Salomon SA) describes a cross-sectional fabrication process of a substantially trapezoidal ski, in which a sliding lining with curbs is provided below the core and a substantially three-layer support shell extending over the entire upper surface down towards the curbs so that it extends over both side surfaces. The uppermost layer of said three-layer shell is the so-called upper lining, i.e. a layer that is derived from thermoplastic material such as acrylonitrilebutadiene styrene polymer (ABS), polyamide (PA) or polycarbonate (PC). Below it is a carrier layer of duroplastic material formed by one or more layers of laminated fiberglass, carbon fiber or Kevlar. The lower layer of said shell again consists of thermoplastic material, which may be identical or similar to the material of the first-mentioned top layer, i.e. upper lining. The lower layer is intended to provide the shape of the ski depending on the passage of said shell through said core, and this function can be assumed only by the outer, covering layer, which in any case is placed over the central layer, which is the supporting layer and provides the ski with the necessary rigidity. The decoration of the ski is done by sublimation of the upper lining, i.e. the uppermost or the outermost layers of thermoplastic material, so the presence of this top layer of thermoplastic material in this solution is indispensable.

Furthermore, EP 0 456 965 (Salomon S.A.) proposes a solution of a decorated ski, in which a so-called upper lining is provided above the load-bearing parts, intended to protect the decoration against knowledge and which consists of two layers. The lower layer of said coating, which is mounted over the supporting elements, consists of a copolymer of styrene and a carboxylic acid or anhydride thereof, or of a compound containing this copolymer, while the upper layer is made of polyamide, in particular so-called polyamide

11. It is predicted that the thickness of each of these layers is only between 0.1 and 1 mm, it should be emphasized that the need for the presence of said layers is again inevitably linked to the increase in the weight of the ski and at the same time to the higher production costs, which are related both to the cost of the layer material itself, including the cost of logistics, as well as to the extra time required to install and process said layers.

Ski decoration is also discussed in the aforementioned EP 0 774 365 BI (Salomon SA), one of the options being the way to realize the decoration by introducing sublimation dyes into the coarse / outer surface of the transparent top lining, about 0 , 1 mm deep into this lining. The disadvantage is that the decoration can be damaged due to mechanical damage, exposure to UV rays and the like. As mentioned, it was proposed in FR-A-2 620 974 that the decoration should be made by sublimation for light impermeable extruded layers, and an additional transparent layer should be installed over the latter. Alternatively, FR-A-2 620 975 proposes first sublimation on the opaque layer, after which this layer, especially by bonding at elevated temperature, is placed on / in the translucent layer, and then such layer composition is applied to the product . In both proposed modes, it is a migration of the dye into a light-tight layer. Furthermore, attempts were made to apply the dye to the inner side for the light of the permeable layer and then to apply the adhesive layer at elevated temperature to the product, which in general may result in uncontrolled continuation of diffusion and / or diffusion. dye penetration, leading to smudging of the pattern or at least negatively affecting the sharpness of the decoration. To prevent this, this inner layer should be provided with a transparent coating before being exposed to the elevated temperature. The latest solutions address the problem of decoration by means of sublimation dyes, which should be applied to thermoplastic plastics, while ensuring that no adverse effects occur during subsequent heating. The present solutions therefore deal with the coloring of a uniform thermoplastic top lining or thermoplastic part of the composite upper lining, while addressing the problem of protecting the resulting decoration against external influences as well as against the effects of temperature required to place the decorated upper lining on the rest of the ski.

It is further known to the applicant in the field of snowboard manufacturing that some manufacturers manufacture their boards in such a way as to assemble a curbside skirt, a laminated lower carrier layer, a core and a laminated upper layer, and then that upper bearing layer, more specifically the outer surfaces of this layer. , treated, decorated and protected against external influences. Such a decorating process is time consuming and involves the use of environmentally friendly dyes, organic solvents and other chemicals. In addition, it is associated with a high risk, since it becomes unusable in the event of defects in decoration. ejected the entire product, including the carrier layer and sliding lining. To this end, manufacturers have so far preferred to separately prepare and decorate the top lining, which is then followed by the installation of only defective semi-finished products over the aforementioned parts, as already described in connection with the patent documents cited.

The present invention deals with a decorated ski. a snowboard consisting of at least a sliding lining along which there are curbs, above it, or. there is at least one single or multilayer lower carrier lining adjacent thereto, further from the core, and in particular from at least one above said core and the sliding lining of the single-layer carrier layer arranged.

According to the invention, at least the uppermost supporting layer is designed as a light at least partially permeable layer of duroplastic material, which, either on its lower / inner facing surface or on its outer / outer surface, is decorated by sublimation sideways from said slip surface. dyes.

It is particularly advantageous if said upper lining is at its lower or lower part. inner surface facing towards the sliding surface, provided with at least substantially impermeable contrasting layer, at its upper or at least substantially impermeable surface. the outer surface facing away from the sliding surface with at least partially permeable protective layer for light.

By means of sublimation dyes, the light-supported, at least partially permeable carrier layer may essentially consist of a laminate, namely a fiberglass reinforced fiberglass material impregnated with a curable artificial resin, in particular e.g. either from the group of epoxy resins, or impregnated with polyurethane or another substance.

Further, said upper support layer may also be embossed, and it can even be calculated that said layer along the sides of the ski or the ski. snowboards extend all the way to the curbs.

The process of making a decorated snowboard or. skiing comprises at least the steps of separately preparing the components, namely at least the sliding linings with associated edges, the lower bearing layer and the upper bearing layer, as well as the embodiment of the core, either before assembly or for the purpose of assembling the aforementioned components, within the scope of such a process at least one step of applying the decorative dye sublimation dye pattern chosen to a suitable carrier is also provided.

The process according to the invention is characterized by the fact that, above and beyond the preparation of the final product, the top or the highest position of the finished product is separately and independently of the preparation of the remaining components of the ski or snowboard. at least partially permeable duroplastic material, which is farthest from the sliding lining, which is then lightened, which is then used with sublimation dyes before being assembled with the other ski components and / or components. decorate snowboards on at least one surface with the pattern chosen at each time.

In a preferred embodiment of the process according to the invention, the uppermost carrier layer further decorated by the sublimation process is further on its inner or outer surface. the lower surface facing surface of the finished product against the sliding surface is coated with a light, at least substantially impermeable contrast layer, on its outer or outer surface. the upper surface of the finished product, so that the surface facing away from the sliding surface is coated with light, at least in a partially permeable protective layer.

Examples of carrying out the invention are shown in the accompanying drawing and will be described in more detail below. In doing so, it shows

FIG. 1 is a schematic cross-sectional view of an embodiment of a ski or a ski. snowboards according to the invention,

FIG. 2 is a schematic cross-sectional view of a further embodiment of a ski or a ski. snowboards according to the invention,

FIG. 3 is an embodiment of a decorative carrier layer of one of the products of the invention shown as detail A in FIG. 2;

FIG. 4 is an alternate embodiment of a decorative carrier layer of one of the products of the invention, again as detail A of FIG. 2.

Ski or. ski board according to FIG. 1 consists of a sliding lining 1, on which the edges 11, 12 are located, further from the center 2 and from the lower carrier layer 3 and the upper carrier layer

4.

Sliding layer 1 is located on the lower surface facing the ski surface. Above said layer 1 is disposed a lower carrier layer 3, preferably consisting of a laminate, namely fiberglass or similar fibrous woven or non-woven fibrous material impregnated with the selected curable material, in particular from the group of artificial resins, thereby obtaining a reinforced duroplastic carrier structure. Said fibrous material may consist e.g. of fiberglass of the so-called group. Glass E by (Glass E by DIN norms). The impregnating agent may be an epoxy resin or a polyurethane-based agent, or another curable agent.

Above the sliding layer 1 and the lower supporting layer 3, a core 2 is available which, depending on the purpose and type of ski, may generally be made of wood, polyurethane foam, metal or other materials. The core 2 itself, as such, does not directly relate to the essence of the present invention, but is essentially intended to provide the shape of the ski, and in particular to hold the carrier layers 3, 4 at an appropriate cross-section along the ski, resulting in the ski's characteristics in terms of flexural and torsional rigidity and similar.

Above said core 2, an upper support layer 4 is available, and according to the invention the upper support layer 4 is decorated. In the example shown, the layer 4 is uniform, single-layer. In general, it is also possible that the upper support layer 4 is composed of several supporting elements at least one above the other, or at least partially adjacent to one another, but for the purposes of the present invention, the term upper support layer 4 denotes only the uppermost or. the outer supporting element of this upper bearing layer 4. The upper bearing layer 4 may be designed in the same manner as explained in the description of the lower bearing layer 3. The upper bearing layer 4 is thus also a reinforced duroplastic material, in particular laminate. based on fiberglass impregnated with artificial resin. The upper support layer 4 may basically be made of the same materials as the previously mentioned lower support layer 3, but may also be of different materials. Of particular importance to the invention is that the upper carrier layer 4 is transparent, namely at least partially translucent to light.

In FIG. 1 shows a further example of a ski or a ski. the snowboard, which again consists essentially of sliding lining 1 with curbs 11, 12, further from the lower carrier layer 3 and from the core 2 available above said layers 1, 3, and through the core 2, the upper carrier layer 4 extends , which in this case is designed in relief and besides, on the sides of the ski or. the ski boards extend downwards towards the base all the way to curbs 11, 12.

In both versions of the ski or. ski boards according to FIG. 1 and 2 is the upper supporting layer 4, which is shown in more detail in FIG. 3 oz. 4, made from at least partially permeable duroplastic laminated material for light decorated with at least one sublimation dye, either on its outer / crumbly side 41 or more preferably on its inner / lower i.e. towards the sliding lining 1 facing 42. The decorated side is in FIG. 3 and 4 are marked with a dashed line, which can also caricaturely illustrate the depth to which they penetrate or sublimate. diffuse dyes.

As can be seen in FIG. 3 and 4, said decorative carrier layer 4 is preferably provided with two coats, wherein a thin protective layer 410 is provided on the upper / outer side 41 for a light permeable protective varnish, and a thin layer is applied on the lower / inner side 42 of the layer 4. light contrast layer 420 for at least substantially impermeable lacquer.

In general, the contrast layer 420 may consist of an arbitrarily selected substance in which, on the one hand, adequate adhesiveness can be ensured with the materials of each adjacent part, e.g. core 2 oz. layers 4 themselves, and on the other hand, the desired light-tightness level, each time.

The protective layer 410 is essentially intended to protect the outer surface 41 of the carrier layer 4 from UV rays, mechanical damage and external influences. The purpose of the contrast layer 420 is to provide the best possible visibility to either the exterior surface 410 or the interior surface 420 of the applied decorative pattern from the outside.

The method of manufacturing a ski or snowboard according to the invention is characterized by the separate fabrication and decoration of the upper carrier layer 4 as a semi-finished product, which is then assembled with the remaining parts 1, 11, 12, 2, 3 of the ski or. snowboards. This layer 4 is made of at least partially permeable duroplastic laminate for light, and in the sublimation dyeing step it is provided with the desired decorative pattern as well as at least a contrasting layer 420 on its underside 42. The upper supporting layer 4 is then decorated. In the usual way, it assembles with the rest of the ski or snowboard. The assembly can be done either by heating and pressing and thus gluing with the remaining parts 1, 11, 12, 2, 3 in the appropriate tool in the press, or by inserting the components 1, 11, 12, 3 into the corresponding mold and pouring it by injecting foam forming components, in particular polyurethane foam, thereby forming a core 2 that connects the remaining components 1, 11, 12, 3 and the decorated upper support layer 4.
