Description

Die Erfindung bezieht sich auf einen Ski mit einer in Abhängigkeit von den Schneeverhältnissen zu wachsenden Lauffläche.The invention relates to a ski with a tread that grows as a function of the snow conditions.

Beim Skilaufen, insbesondere beim Skilanglauf, kommt es häufig entscheidend auf das richtige Wachsen der Lauffläche der Skier an. Im Handel werden eine Reihe von Hartwachsen und Klister angeboten, die auf unterschiedliche Schneeverhältnisse abgestimmt sind und sich jeweils für einen mehr oder weniger großen Temperaturbereich eignen.When skiing, especially cross-country skiing, the correct growth of the running surface of the skis is often crucial. A number of hard waxes and klister are available on the market, which are matched to different snow conditions and are each suitable for a more or less wide temperature range.

Da sich die Schnee- und Temperaturverhältnisse während eines Skilaufes zeitlich und örtlich ändern können, ist es unter Umständen erforderlich, den Wachsauftrag auf der Lauffläche der Skier im Verlaufe des Skilaufes zu wechseln, d.h. den veränderten Verhältnissen anzupassen. Die richtige Wahl des Wachses fällt jedoch dann schwer, wenn der Skiläufer nicht genau über die Temperatur des Schnees informiert ist. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die bekannten Skier so zu verbessern, daß dem Skiläufer jederzeit und an jedem Ort diejenige Information zur Verfügung steht, die er zur Auswahl des richtigen Wachses benötigt.Since the snow and temperature conditions can change temporally and locally during a ski run, it may be necessary to change the wax application on the tread of the skis during the ski run, ie the adapt to changing circumstances. Choosing the right wax is difficult, however, if the skier is not exactly informed about the temperature of the snow. The present invention is based on the object of improving the known skis in such a way that the skier has the information available at any time and at any place which he needs to select the right wax.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf der Oberseite des Skis eine Temperaturmeß- und Temperaturanzeigevorrichtung vorgesehen iSt. Durch die Messung und Anzeige der jeweiligen Schneetemperatur kann der Skiläufer zu jeder Zeit und an jedem Ort überprüfen, mit welchem Wachs er die optimalen Laufbedingungen erzielen kann. So kann er nicht nur zu Beginn seines Laufes das richtige Wachs auswählen, sondern er kann auch bei Änderung der Schnee- und/oder Temperaturverhältnisse im Verlaufe seines Skilaufes umwachsen, so daß er selbst stets für optimale Laufbedingungen sorgen kann.This object is achieved in that a temperature measuring and temperature display device is provided on the top of the ski. By measuring and displaying the respective snow temperature, the skier can check at any time and any place with which wax he can achieve the optimal running conditions. So he can not only choose the right wax at the beginning of his run, but he can also change his face when the snow and / or temperature conditions change during the course of his skiing so that he can always ensure optimal running conditions.

In bevorzugter Weiterbildung der Erfindung weist die Temperaturmeßvorrichtung ein Bimetallthermometer auf, dessen Zeiger auf einer die Schneetemperatur anzeigenden Skala abläuft. Weitere Einzelheiten der Erfindung, die sich auf die Ausgestaltung sowohl der Meßvorrichtung als auch der Anzeigevorrichtung beziehen, sind in den Unteransprüchen angegeben. Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben und erläutert.In a preferred development of the invention, the temperature measuring device has a bimetal thermometer, the pointer of which runs on a scale indicating the snow temperature. Further details of the invention, which relate to the design of both the measuring device and the display device, are specified in the subclaims. The invention is described and explained in more detail below with reference to an embodiment shown in the drawing.

Es zeigen:

  • Fig. 1 ein Teilstück eines Skis mit einer Temperaturmeß- und Temperaturanzeigevorrichtung in der Draufsicht und
  • Fig. 2 das Teilstück des Skis gemäß Fig. 1 im Längsschnitt.
Show it:
  • Fig. 1 shows a portion of a ski with a temperature measuring and temperature display device in plan view and
  • Fig. 2 shows the portion of the ski of FIG. 1 in longitudinal section.

Die Oberseite 10 eines Ski.s 11 weist eine flache, rechteckförmige Ausnehmung 12 auf, in die eine Aluminiumplatte 13 mit einer Acrylglasabdeckung 14 so eingelassen ist, daß die Abdeckung mit der Oberseite des Skis bündig abschließt. Im Mittelbereich der Aluminiumplatte 13 sind in unmittelbarer Nachbarschaft zwei je eine Bimetall-Spiralfeder 15 aufweisende Thermometer in gutem Wärmekontakt mit der Aluminiumplatte montiert. Die mit den Spiralfedern 15 verbundenen Zeiger 16 der beiden Thermometer beschreiben je einen Halbkreis, wobei die Grundlinien der beiden Halbkreise parallel und unmittelbar benachbart verlaufen. Die Bewegung der beiden Zeiger 16 verläuft in entgegengesetzten Richtungen; aber auch das Gegenteil ist möglich.The top 10 of a ski 11 has a flat, rectangular recess 12, into which an aluminum plate 13 with an acrylic glass cover 14 is embedded so that the cover is flush with the top of the ski. In the middle area of the aluminum plate 13, two thermometers each having a bimetal spiral spring 15 are mounted in good thermal contact with the aluminum plate. The pointers 16 of the two thermometers connected to the spiral springs 15 each describe a semicircle, the baselines of the two semicircles running parallel and immediately adjacent. The movement of the two pointers 16 runs in opposite directions; but the opposite is also possible.

Jedem Zeiger 16 ist eine Skala 17 bzw. 18 unterlegt, Die Skala 17 ist in Temperaturbereiche eingeteilt, die den empfohlenen Verwendungsbereichen der auf die Lauffläche 19 des Skis 11 aufzutragenden Hartwachse entspricht, während die Skala 18 eine Bereichseinteilung aufweist, die den empfohlenen Verwendungsbereichen der auf die Lauffläche 19 aufzutragenden Klister entsprechen. Beide Skalen 17 und 18 reichen im Ausführungsbeispiel von -25 °C bis +25'oC. Selbstverständlich können die Bimetall-Spiralfedern 15 der beiden Thermometer in Material und Stärke so ausgewählt werden, daß sich auch andere, für Spezialzwecke geeignete Meßbereiche ergeben.Each pointer 16 is underlaid with a scale 17 and 18, respectively. The scale 17 is divided into temperature ranges that correspond to the recommended areas of use of the hard waxes to be applied to the tread 19 of the ski 11, while the scale 18 has a division that corresponds to the recommended areas of use the tread 19 correspond to klister to be applied. In the exemplary embodiment, both scales 17 and 18 range from -25 ° C. to + 25 ° C. Of course, the bimetal spiral springs 15 of the two thermometers can be selected in material and thickness in such a way that other measuring ranges suitable for special purposes also result.

Zur Erleichterung der Ablesung der angezeigten Temperatur sind die Bereiche der beiden Skalen 17 und 18 unterschiedlich gefärbt. Zweckmäßigerweise werden hierfür diejenigen Farben gewählt, mit denen die Hersteller die für die unterschiedlichen Verwendungsbereiche im Handel angebotenen Hartwachse und Klister einfärben.To facilitate the reading of the displayed temperature, the areas of the two scales 17 and 18 are colored differently. For this purpose, those colors are expediently chosen with which the manufacturers differ Color the hard wax and klister offered for use in retail.

Die durchsichtige Abdeckung 14 schließt die gesamte Temperaturmeß- und Temperaturanzeigevorrichtung auf der Aluminiumplatte 13 schnee- und wasserdicht ab, so daß stets eine störungsfreie Messung und Anzeige der Schneetemperatur gewährleistet ist.The transparent cover 14 closes the entire temperature measuring and temperature display device on the aluminum plate 13 in a snowproof and waterproof manner, so that a trouble-free measurement and display of the snow temperature is always guaranteed.

Die Erfindung ist nicht auf das Ausführungsbeispiel beschränkt. Modifikationen der räumlichen Zuordnung der beiden Meß- und Anzeigevorrichtungen, andere Ausgestaltungen der Skalen und die Zusammenfassung beider Meß- und Anzeigevorrichtungen in eine gemeinsame Vorrichtung mit gemeinsamer Skala oder getrennten Skalen für Hartwachse und Klister fallen ebenso in den Schutzbereich der Erfindung, wie eine Ausgestaltung, bei der eine einzige Temperaturmeßvorrichtung zwei Temperaturanzeigevorrichtungen aufweist, also beispielsweise zwei um 180 ° versetzte Zeiger, von-denen der eine eine Skala für Hartwachse und der andere eine Skala für Klister überstreicht.The invention is not restricted to the exemplary embodiment. Modifications of the spatial assignment of the two measuring and display devices, other configurations of the scales and the combination of both measuring and display devices in a common device with a common scale or separate scales for hard waxes and klister also fall within the scope of the invention, as does one configuration which a single temperature measuring device has two temperature display devices, for example two pointers offset by 180 °, of which one passes over a scale for hard waxes and the other over a scale for klister.
