    专利说明:

    The present invention relates to a snow glider. The vast majority of snow gliders are the well-known winter sports equipment, skis and snowboards.
    For both skiers and snowboarders, the weight of the ski or snowboard is decisive for good maneuverability. In particular, handling can deteriorate if, due to unfavorable weather conditions, slush freezes or ice forms on the ski or snowboard (or in general: on the snow glider).
    The weight is also of central importance for ski touring, which has become more and more popular in recent years, in which a mountain is climbed before the descent with skis typically already attached to the foot. For snowboarders there are so-called splitboards, which can be separated into two ski-like components, so that although a descent with a snowboard is possible, the ascent can take place with the board split. In order not to make the ascent unnecessarily difficult, it is desirable to use skis or splitboard components that are as light as possible. It is therefore of central importance to prevent slush from freezing on or the formation of a layer of ice.
    As a rule, however, this cannot be prevented because the surface of the ski or snowboard is exposed to sunlight and is heated as a result. This causes snow that comes into contact with the surface to melt, which means that it adheres very well to the surface. Under certain circumstances, freezing due to airflow or a change in temperature can also be promoted in this way.
    This can lead to the fact that the snow / mud layer adhering to the ski or snowboard increases the weight by 2 to 3 kilograms. This effect is particularly pronounced on dark surfaces due to the increased warming.
    It is accordingly the aim of the present invention to alleviate or overcome the present problem. This is achieved with the object which has all the features of claim 1. Advantageous refinements can be found in the dependent claims. Furthermore, a method for producing the snow glider is also disclosed in the claims.
    According to the invention it is provided that the snow glider, in particular a ski or a snowboard, comprises an elongated, plate-like base body with an underside suitable for sliding on snow. The snow glider is characterized in that an upper side of the plate-like base body is provided with a reflective layer in order to reflect heat-generating light components.
    The reflective layer is designed to reflect heat-generating light components so that they cannot lead to the snow glider heating up. As a result, less slush accumulates on the snow glider, since it has a lower temperature difference to the ambient temperature. The weight of the snow glider therefore does not increase or does not increase as much as with a snow glider that does not have a reflective layer on the surface of its base body, which leads to a significantly more pleasant ascent on a ski tour and better handling on the descent.
    According to the invention it can also be provided that the reflective layer contains lenticular pigments and / or a lenticular additive and / or metal flakes.
    By providing lenticular pigments and / or a lenticular additive and / or metal flakes, the incident light is reflected in a spectral range that prevents or mitigates heating of the underlying layer. The lenticular pigments or the lenticular additive bring about a particularly good reflection of incident light and are far superior to the metal flakes with regard to the advantages that can be achieved by the invention. Another disadvantage of using metal flakes is that they have a strongly distinctive, glittering appearance which is perceived as very extravagant. An application example for a lenticular color additive that is known to everyone is traffic signs or road markings, which give off a large part of them again when light falls on them.
    According to a further optional development of the invention it is provided that the reflective layer is translucent and optionally has a transmission of more than 25%, preferably more than 50% and preferably more than 53% over the wavelength range from 420 nm to 650 nm .
    Due to the translucent design of the reflective layer, particularly appealing optical designs of the snow glider are possible, in which darker colors arranged under the reflective layer are also possible.
    Another advantage of this is that the known manufacturing processes for snow gliders can essentially be retained and only the reflective layer is to be applied to snow gliders that have already been completely designed.
    Such translucent reflective layers, some of which also have lenticular pigments and / or lenticular additives, are known from the conception for greenhouses, since it is advantageous here if a high amount of perceivable light in the range of approx nm wavelength can penetrate the greenhouse, the heat-generating light components such as UV light (with a wavelength range of 100 to 380 nm) and near-infrared light (also called NIR light with a wavelength range of 780 to approx. 1400 nm) but not or can only penetrate the greenhouse to a limited extent
    According to a further modification of the invention it is therefore provided that the reflective layer is designed to reduce the transmission of UV radiation and / or NIR radiation, preferably in the IR-A spectrum.
    It can be provided that the transmission of UV light, that is to say over the range from 100-380 nm, through the reflective layer is reduced to less than 5%, preferably to less than 3%.
    It can also be provided that the transmission of near-infrared light over the range between 780-1400 nm through the reflective layer is reduced to below 55%. Alternatively or additionally, it can be provided that the transmission of near-infrared light for a range between 850-1200 nm is reduced to below 40%, preferably to below 30%.
    According to an optional modification of the present invention it can be provided that the reflective layer is covered by a transparent film, which preferably forms the top of the snow glider.
    This transparent film can fulfill the purpose of a protective layer which ensures adequate protection of the reflective layer against environmental influences and also mechanical influences.
    The invention further relates to a method for producing a snow glider according to one of the preceding claims, wherein in the method the reflective layer is applied to a transparent film, preferably printed, and the film provided with the reflective layer is connected to the base body of the snow glider, so that the reflective layer is arranged on the surface of the base body.
    By applying the reflective layer to the film, the attachment of the reflective layer to the snow glider together with the film is possible, which promotes a simple workflow. In addition, the thickness of the reflective layer on a flat film can be determined much more precisely and more easily than would be the case on a surface of a base body for a snow glider, since these are usually not flat but have a three-dimensional shape. Thus, the amount or the thickness of the required reflective layer can be determined exactly and unnecessary material expenditure can be avoided.
    According to the invention, it can preferably be provided that the film provided with the reflective layer is pressed with the base body of the snow glider.
    The compression of several layer-like components of a snow glider is the usual form for joining the snow glider, so that the known processes can be largely retained even when the reflective layer according to the invention is provided.
    Furthermore, in the method for producing a snow glider, it can be provided that the reflective layer is applied to a first side of the transparent film which faces the base body when it is connected to the base body.
    Further features, details and advantages of the invention will become apparent from the following description of the figures. It shows: FIG. 1: a schematic cross-sectional view of the snow glider according to the invention.
    In the cross-sectional view of the snow glider 1 shown in Fig. 1, a base body 2 is shown, which has an underside 3 for sliding on snow. It is clear to a person skilled in the art that the base body 2 can consist of a large number of different layers and cores which are advantageous for the driving properties and the stability.
    On the side facing away from the underside 3, the plate-like base body 2 has an upper side 4 which is covered by a reflective layer 5. This reflective layer 5 is designed to reflect incident light 8 so that heating of the base body 2 arranged underneath is reduced or prevented.
    According to an advantageous embodiment, the reflective layer 5 reflects light 8 only in certain wavelength ranges and allows light wavelengths to pass in the visible range. For example, a particularly high proportion of UV light will typically not pass through the reflective layer 5 and light in the near-infrared range 6 is also reflected back through the reflective layer 5. The transmission of UV light, that is to say over the range from 100-380 nm, can accordingly be reduced by the reflective layer 5 to less than 5%, preferably to less than 3%. Alternatively or additionally, it is possible that the transmission of NIR light 6, i.e. light over the range between 780-1400 nm, through the reflective layer 5 to below 55%, preferably for a range between 850-1200 nm to below 40%, is preferably reduced to below 30% for the range between 850-1200 nm.
    The advantage of the translucent design of the reflective layer is that already existing graphic elements on the top 4 of the base body 2 are still visible even after the reflective layer 5 has been applied, so that the provision of the reflective layer 5 only minimally interferes with the usual workflows Making a snow glider engages. In order to achieve the translucent effect, it is necessary for light in the visible region 7 to be able to pass through the reflective layer 5 with sufficient strength. Thus, a transmission of more than 25%, preferably more than 50% and preferably more than 53% over the entire wavelength range from 420 nm to 650 nm can meet the required transmission of light in the visible range 7.
    It is therefore possible to apply a color layer to the top 4 of the base body 2 and only then to arrange the reflective layer 5 over it. However, the invention also includes the fact that the reflective layer also defines the optically perceptible external appearance of the snow glider 1 at the same time. In other words, the design of the snow glider 1 is produced with the reflective layer 5, so that in this case a separate colored layer is not required. Here, for example, a lenticular color additive and / or lenticular pigments can be mixed into the color used to create the color layer, whereby the desired reflective layer 5 is produced.
    The illustrated in Fig. 1 arranged above the reflective layer 5 transparent film 9 is optional, so does not necessarily have to be provided so that the snow glider 1 can also be flush with the reflective layer on its surface 10.
    The method for producing the shown snow glider 1 can be carried out in an advantageous manner in that a film, which can also be the transparent film 9, is provided on one of its flat sides with the reflective layer, for example by printing or the like. This film provided with the reflective layer 5 is then connected to the base body 2 of the snow glider 1, in particular pressed, so that the film is firmly connected to the base body 2.
    A possible concrete implementation of the invention is shown below by way of example, in particular how the reflective layer can be formed.
    In the present case, the reflective layer is produced by adding special additives to the printing ink which is used for printing the transparent film 9. After the film 9 has been printed, it is placed on the upper side 4 of the base body 2 and pressed with the base body 2.
    In order to achieve the desired effects of the invention to an advantageous extent, a printing ink is mixed which, for example, has a mass fraction of 5-7%, preferably approx. 6%, of the color additive from the IRIOTEC 9000 series. In this series, the manufacturer Merck offers the products IRIOTEC 9870, IRIOTEC 9875 and IRIOTEC 9880, all of which are suitable for the present invention, whereby the best results in terms of the reflection of undesired light components are achieved with IRIOTEC 9880, but with lower transmission visible light are to be accepted.
    If, on the other hand, great importance is attached to the transmission of visible light, then IRIOTEC 9870 is a good choice, as this is quite color-neutral. A middle way would be to choose IRIOTEC 9875, which, however, has a violet reflective color and is located between IRIOTEC 9870 and IRIOTEC 9880 in terms of the reflective properties of the undesirable heat-generating light components.
    The IRIOTEC 9000 product line was originally developed by Merck for architectural applications and also for greenhouses.
