Description

Schnee- und/oder Eisoberfläche Snow and / or ice surface
Die Erfindung betrifft eine Schnee und/oder Eisoberfläche für den Wintersport nach dem Oberbegriff des Hauptanspruches.The invention relates to a snow and / or ice surface for winter sports according to the preamble of the main claim.
Schnee- und Eispisten für den Ski-, Snow-Board, Schlittschuh-, Bob- und Rodelsport usw. (nachstehend als "Piste" bezeichnet) werden neben dem reinen sportlichen Anspruch zunehmend zu Zwecken des Vergnügens und der Freizeitgestaltung genutzt. Ausdruck hierfür sind z. B. zunehmende Verbreitung künstlicher Beschneiung zur Verlängerung der Wintersportsaison und qualitative Beeinflussung der Pisten, Indoor-Skihallen, Schlittschuh- Hallen mit Discothek, beleuchtete Loipen, Nachtveranstaltung unter Flutlicht usw.Snow and ice slopes for skiing, snow boarding, ice skating, bobsleighing and tobogganing, etc. (hereinafter referred to as "slopes") are increasingly being used in addition to the purely athletic demands for the purposes of fun and leisure. The expression for this are e.g. B. Increasing use of artificial snow to extend the winter sports season and influence the quality of the slopes, indoor ski halls, ice skating halls with discotheque, illuminated trails, night events under floodlights, etc.
Hierbei handelt es sich um die derzeitigen Erscheinungsformen des "Wintersports" (auch wenn z.B. in Hallen dieser außerhalb der Wintersaison betrieben werden kann) .These are the current manifestations of "winter sports" (even if, for example, it can be operated outside the winter season in halls).
Bisher wird dabei der Schnee- bzw. das Eis mit seiner natürlichen weißen Farbe belassen bzw. farblich unbehandelt künstlich erzeugt. Eis und vor allem Schnee kann dabei bei entsprechender Nässe, durch die (Ab-) Nutzung bedingt und/oder aufgrund von Licht- bzw. Beleuchtungsverhältnissen auch graue bzw. dunkle Farbtöne aufweisen, was jedoch unerwünscht ist, da der Anblick einer derartigen Schneebzw. Eisfläche optisch "langweilig" wirkt. Der Erfindung liegt die Aufgabe zugrunde, einen Schnee zu schaffen, der diese Nachteile nicht aufweist. Weiter ist es erwünscht, Pisten für den Wintersport durch gezielte Einzelmaßnahmen oder durch die Kombination mehrerer Maßnahmen optisch attraktiver und für den Betrachter/Sportler auch spannender und/oder witziger zu gestalten.So far, the snow or ice has been left with its natural white color or artificially produced untreated. Ice and, above all, snow can be gray or dark in color if there is sufficient wetness, due to (wear) usage and / or due to light or lighting conditions, which is undesirable, however, because the sight of such snow or Ice surface looks "boring". The invention has for its object to provide a snow that does not have these disadvantages. Furthermore, it is desirable to make slopes for winter sports optically more attractive through targeted individual measures or through the combination of several measures and also more exciting and / or fun for the viewer / athlete.
Erfindungsgemäß wird dies durch einen Schnee mit den Merkmalen des Hauptanspruches gelöst. Die Unteransprüche geben vorteilhafte Ausführungsformen wieder.According to the invention this is solved by a snow with the features of the main claim. The subclaims represent advantageous embodiments.
Beim Einfärben von Schnee bzw. Eis kann dies auf natürlichen Pisten dadurch geschehen, daß Farbstoff auf die Farbe bzw. Lauffläche und/oder auf die normalerweise unbefahrenen (Seiten-) Ränder gegeben wird oder auch vor und/oder während der Erzeugung des Schnees bzw. des Eises und/oder vor bzw. während der Verteilung und Aufbringung des Schnees bzw. des Eises zugegeben wird.When snow or ice is colored, this can happen on natural slopes by adding dye to the paint or tread and / or to the normally unoccupied (side) edges or before and / or during the production of snow or of the ice and / or before or during the distribution and application of the snow or the ice is added.
Insbesondere eignet sich die Farbbehandlung vor, während und/oder nach der Erzeugung von Eiskristallen in Maschinen, welche aus einer wässrigen Mischung bzw. Lösung einen Eiskristallbrei erzeugen, der mit gewünschtem Eisanteil auf Pisten aufgebracht wird. Die Farbe des Eises kann zusätzlich durch geeignete Lampen und deren Farbe bzw. Farbspektrum vorteilhaft beeinflußt werden. Das Eis kann durch Blautöne "kühl", durch Rot- und Gelbtöne "warm" durch Grüntöne "fröhlich", durch Schwarztöne "geheimnisvoll" erscheinen usw. Insbesondere bietet das Zusammenwirken von Eis- bzw. Schneefärbung und Farbe bzw. Farbspektrum der Lampen interessante Varianten. Dem farblichen Zusammenwirken sind hier keine Grenzen gesetzt. Die Farbe des Eises bzw. des Schnees und die Farbe bzw. das Farbspektrum einer Lampe können Farbeffekte durch Addition, Subtraktion, Auslöschung und/oder Verstärkung auslösen durch Zu-, Um-, Ab- und/oder Zusammenschaltung einzelner Lampen sogar dynamisch gestaltet werden können. Ebenso können bewegliche Lampen eingesetzt werden.The color treatment is particularly suitable before, during and / or after the generation of ice crystals in machines which produce an ice crystal slurry from an aqueous mixture or solution which is applied to slopes with the desired amount of ice. The color of the ice can also be advantageously influenced by suitable lamps and their color or color spectrum. The ice can appear "cool" through blue tones, "warm" through red and yellow tones, "mysterious" through green tones, "mysterious" through black tones, etc. In particular, the interaction of ice or snow coloring and the color or color spectrum of the lamps offers interesting variants . There are no limits to the color interaction here. The color of the ice or snow and the color or the color spectrum of a lamp can trigger color effects through addition, subtraction, extinction and / or amplification through connection, switchover, disconnection and / or interconnection individual lamps can even be designed dynamically. Movable lamps can also be used.
Hierzu wird insbesondere vorgeschlagen, fluoreszierende bzw. luminiszierende Stoffe beizugeben (nachfolgend als Fluoreszenz bezeichnet) . Diese sind insbesondere für Pisten interessant, welche im künstlichen Licht erhellt werden, wie dies z.B. in Eishallen oder bei Pisten im Nachtbetrieb der Fall ist. Die Zugabe kann für "natürlichen" Schnee (oder Eis) als auch für eingefärbten Schnee (oder Eis) erfolgen.For this purpose, it is proposed in particular to add fluorescent or luminescent substances (hereinafter referred to as fluorescence). These are particularly interesting for slopes that are illuminated in artificial light, such as in ice rinks or on slopes at night. The addition can be for "natural" snow (or ice) as well as for colored snow (or ice).
Die Fluoreszenz wird durch sogenannte "Schwarzlichtlampen" oder andere geeignete Lampen ausgelöst. Wird der fluoreszierende Stoff auf die Oberfläche des Eises bzw. des Schnees gegeben, so wird beispielsweise der Eindruck frischgefallenen Schnees bzw. frischen Eises erweckt, insbesondere wäre die Zugabe vereinzelt erfolgt und Lichtreflektion besonnter Pisten ähnlich ist. Ebenso können Schnee bzw. Eis mit hohem Anteil von fluoreszierenden Stoffen in der Fläche und mit entsprechender Beleuchtung "glühen" und eine besondere optische und sinnliche Wahrnehmung auslösen.The fluorescence is triggered by so-called "black light lamps" or other suitable lamps. If the fluorescent substance is placed on the surface of the ice or snow, for example, the impression is given of freshly fallen snow or fresh ice, in particular the addition would have been sporadic and light reflection of sunlit slopes is similar. Likewise, snow or ice with a high proportion of fluorescent substances in the surface and with appropriate lighting can "glow" and trigger a special visual and sensual perception.
Weiter wird vorgeschlagen eine Piste bzw. Teile einer Piste mit transparentem und/oder undurchsichtigem "Nebel" zu belegen. Dieser Nebel kann mit niedrigsiedenden Flüssigkeiten oder anderen Substanzen (z.B. Kohlendioxid, Stickstoff usw.) mit feinsten Aerosolen (z.B. aus Ölen oder Wasser) und/oder mit Wasserdampf hergestellt werden. Der Nebel kann durch ein geeignete Beleuchtung und/oder durch Farbreflektion des Eises bzw. des Schnees und/oder durch Fluoreszenz farblich gestaltet bzw. variiert werden. Der Nebel kann dabei die Piste in voller horizontaler Ausdehnung oder auch nur Teile der Piste horizontal belegen, ebenso ist die vertikale Belegung der Piste durch die Dichte des Nebels, die Strömungsverhältnisse durch thermischen Auf- bzw. Abtrieb oder Kombination hiervon definierbar. Hierbei können entsprechende Ventilationseinrichtungen, die vorteilhafterweise in bereits vorgesehenen Lampen integriert werden, wobei die Lampen den Nebel anstrahlen, verstärkt werden. Es kann spannend sein, eine farblich abgestimmte, ggf. beleuchtete und/oder fluoreszierende Piste mit Bodennebel zu durchfahren oder z.B. Curling im Nebel zu spielen.It is also proposed to cover a slope or parts of a slope with transparent and / or opaque "fog". This mist can be produced with low-boiling liquids or other substances (e.g. carbon dioxide, nitrogen, etc.) with the finest aerosols (e.g. from oils or water) and / or with water vapor. The fog can be colored or varied by suitable lighting and / or by color reflection of the ice or snow and / or by fluorescence. The fog can cover the slope in full horizontal extent or only parts of the slope horizontally, as is the vertical occupancy of the slope by the density of the mist, the flow conditions can be defined by thermal up or down or a combination thereof. Corresponding ventilation devices, which are advantageously integrated in lamps already provided, the lamps illuminating the mist, can be reinforced. It can be exciting to drive through a color-coordinated, possibly illuminated and / or fluorescent slope with ground fog or to play curling in the fog.
Insbesondere ist so die optische Erscheinung einer Piste im Verlauf der Zeit veränderbar. Insbesondere sind Variationen in der Beleuchtung zusammen mit gelegentlicher Fluoreszenz sowie das sporadische Erscheinen von horizontalem und/oder vertikalem Nebel überraschend spannend und daher kurzweilig.In particular, the visual appearance of a slope can be changed over time. In particular, variations in lighting together with occasional fluorescence and the sporadic appearance of horizontal and / or vertical fog are surprisingly exciting and therefore entertaining.
Außer Schnee- und Eisoberflächen im Freien, können so auch zum Wintersport dienende Innenraumflachen schon während der Verbringung des Schnees in diese mit in oder auf die Oberfläche aufgebrachten Farbstoffen, insbesondere solchen die bei bestimmter Beleuchtung ansprechend fluoreszieren oder funkeln (eingebrachte Eiskristalle) versehen werden.In addition to snow and ice surfaces outdoors, even indoor surfaces used for winter sports can be provided with dyes applied to or on the surface while the snow is being brought into them, in particular those that fluoresce or sparkle appropriately under certain lighting (incorporated ice crystals).
Niedrigsiedende Zusatzstoffe können diesen kalten Flächen immer dann wenn wärmere Luft (ggf. besonders für diesen Zwecke erzeugt) gleichzeitig anwend ist, Nebel erzeugen.Low-boiling additives can create fog on these cold surfaces whenever warmer air (possibly created especially for this purpose) is used at the same time.
Piste, die derart vorbereitet sind, z.B. durch am Rand der zum Wintersport genutzten Fläche angeordnete, im wesentlichen auf den Schnee und/oder die Eisoberfläche aufleuchtende Lampen, können insbesondere abend und nachts die im Winter kurzen Tage im Freien länger für den Wintersport nutzbar machen. Wenn die Lampen weiter mit Luftauftriebseinrichtungen versehen sind, und sie wenigstens einen Teil ihres Lichtscheins in den Bereich des Luftauftriebs richten, können optische "Begrenzungen" von Pisten wandähnlich erzeugt werden. Slopes that are prepared in this way, for example by lamps arranged on the edge of the area used for winter sports and essentially lighting up on the snow and / or the ice surface, can make the short days outdoors in winter longer usable for winter sports, especially in the evening and at night. If the lamps continue to be provided with air buoyancy devices, and at least they A part of their light shine in the area of the air buoyancy, optical "limits" of slopes can be created like a wall.
