The hollow bodies consist of two plug-in trays, one of which has a shell abutting the underside of the film edge and the other shell has a sliding surface forming, annular projection.

Die DE 10 2004 023086 A1 beschreibt ein Gleitflächenelement für Skisprunganlagen, gekennzeichnet durch die Gesamtheit der Merkmale, dass auf einem rechteckigen Unterbau-Flächenelement entlang seinen beiden Außenlängsrändern jeweils ein erstes Leistenelement und im Längsmittelbereich voneinander beabstandet zwei zweite Leistenelemente befestigt sind, wobei das jeweilige erste Leistenelement und das zugehörige zweite Leistenelement eine Skispur seitlich begrenzen und zwischen dem jeweiligen ersten und dem zugehörigen zweiten Leistenelement auf dem Unterbau-Flächenelement ein Grundflächenelement aus einem Polymermaterial festgelegt ist, an dem Keramiknoppenkörper in einem Rastergitter voneinander beabstandet fixiert sind, die mit ihrer Stirnfläche aus der Oberseite des jeweiligen Grundflächenelements definiert vorstehen, wobei das jeweilige Grundflächenelement an seiner Oberseite mit einem Entwässerungsrillensystem ausgebildet ist. Die im Grundflächenelement angeordneten Keramiknoppenkörper sind fixiert.The DE 10 2004 023086 A1 describes a Gleitflächenelement for ski jumping equipment, characterized by the totality of features that on a rectangular base element along its two outer longitudinal edges a first strip member and longitudinally spaced from each other two second strip elements are attached, wherein the respective first strip element and the associated second strip element a Bounding the ski track laterally and between the respective first and the associated second strip element on the substructure surface element is a base element made of a polymer material is fixed to the ceramic knob body in a grid grid spaced from each other, which protrude defined with its face from the top of the respective base member, wherein the respective base member is formed on its upper side with a drainage groove system.

Die DE 202 11 137 U1 beschreibt ein Gleitflächenelement für künstliche Skianlagen, insbesondere für Skisprunganlagen, für Langlaufloipen oder für Gleithänge, mit einer Noppenprofilierten Gleitfläche, wobei das Gleitflächenelement ein Grundflächenelement aus einem Polymermaterial aufweist, in dem Keramikkörper in einem Gitterraster voneinander beabstandet fixiert sind, die mit ihrer Stirnfläche über das Grundflächenelement definiert überstehen. Das Grundflächenelement ist dabei mit Sacklöchern ausgebildet, in welchen die Keramikkörper fixiert sind. Die Sacklöcher und die Keramikkörper sind abmessungsmäßig aneinander derart angepasst, dass die im Grundflächenelement fixierten Keramikkörper mit ihrer Stirnfläche über das Grundflächenelement definiert überstehen. Das Sackloch ist dabei zylinderförmig ausgebildet, während der Keramikkörper mit einer Mantelfläche so ausgebildet ist, dass diese zur Stirnfläche hin konisch verjüngt ist. Der Keramikkörper ist somit an seiner Grundfläche mit einem größeren Durchmesser ausgebildet als an seiner Stirnfläche. Dieser sich konisch zur Grundfläche vergrößernde Keramikkörper ist in das zylinderförmige Sackloch so eingepresst, dass der harte Keramikkörper in dem relativ weichen, polymeren Grundflächenelement formschlüssig (unlösbar) fixiert ist.The DE 202 11 137 U1 describes a Gleitflächenelement for artificial ski facilities, especially for ski jumping facilities, for cross-country trails or for gliding length, with a nub profiled sliding surface, wherein the sliding surface element comprises a base element made of a polymer material, are fixed in the ceramic body in a grid spaced from each other, with its end face on the base surface element survive survive. The base member is formed with blind holes in which the ceramic body are fixed. The blind holes and the ceramic bodies are dimensionally adapted to one another such that the ceramic bodies fixed in the base element project with their end face over the base surface element. The blind hole is cylindrical, while the ceramic body is formed with a lateral surface so that it is tapered conically towards the end face. The ceramic body is thus formed on its base with a larger diameter than on its end face. This ceramic body, which tapers conically with respect to the base area, is pressed into the cylindrical blind hole in such a way that the hard ceramic body is fixed in a form-fitting (insoluble) manner in the relatively soft, polymeric base surface element.

Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde ein Gleitflächenelement anzugeben, dessen Verwendung den Verschleiß der Ski reduziert und dessen eigener Verschleiß nur geringe Instandsetzungskosten hervorruft.The present invention is therefore an object of the invention to provide a Gleitflächenelement whose use reduces the wear of the ski and its own wear causes only low repair costs.

Die Aufgabe wird erfindungsgemäß gelöst durch ein Gleitflächenelement mit den Merkmalen des Anspruches 1.The object is achieved by a Gleitflächenelement with the features of claim 1.

Durch die lösbare Befestigung des Gleitelementes mit dem Träger mittels einer am Träger angeordneten Befestigungsvorrichtung kann das Gleitelement ohne Ausbau des gesamten Gleitflächenelementes einfach ausgetauscht werden.Due to the releasable attachment of the sliding element to the carrier by means of a fastening device arranged on the carrier, the sliding element can be easily replaced without removing the entire sliding surface element.

Überraschenderweise wird die Funktionalität des Gleitelements hiervon nicht beeinträchtigt und eine erhebliche Aufwands- und Kostenersparnis erzielt.Surprisingly, the functionality of the sliding element of this is not affected and achieved a considerable effort and cost savings.

Als günstig hat sich eine noppen-, quader-, zylinder-, pyramiden-, walzen- oder kugelförmige Geometrie des Gleitelementes erwiesen.As low has a knobbed, cuboid, cylindrical, pyramidal, cylindrical or spherical geometry of the sliding element has been found.

Das Gleitflächenelement kann vorteilhaft mehrere Gleitelemente aufweisen. Diese können auch unterschiedliche Geometrien aufweisen. Somit kann das Gleitflächenelement durch die Verwendung unterschiedlicher Gleitelementgeometrien an die unterschiedlichen Einsatzbedingungen angepasst werden. Auch der Einsatz von Gleitelementen aus unterschiedlichen Materialien in verschiedenen Bereichen eines Gleitflächenelementes oder in unterschiedlichen Bereichen der Skianlage ist somit einfach realisierbar.The sliding surface element may advantageously have a plurality of sliding elements. These can also have different geometries. Thus, the Gleitflächenelement can be adapted by the use of different Gleitelementgeometrien to the different conditions of use. The use of sliding elements made of different materials in different areas of a sliding surface element or in different areas of the ski system is thus easy to implement.

Um die durch die Reibung zwischen Ski und Gleitelement entstehenden Wärme abzuführen, werden die Gleitflächenelemente mit Wasser, das über die Gleitflächenelemente gleitet wird, gekühlt. Um ein Eindringen von Wasser oder Staub und Schmutz in die Befestigungsvorrichtung zur Verbindung von Gleitelement und Träger zu verhindern, hat es sich als vorteilhaft erweisen, ein Dichtelement zwischen Gleitelement und Träger anzuordnen.To dissipate the heat generated by the friction between the ski and the sliding element, the sliding surface elements are cooled with water which is slid over the sliding surface elements. In order to prevent ingress of water or dust and dirt into the fastening device for connecting the sliding element and the carrier, it has proven to be advantageous to arrange a sealing element between the sliding element and the carrier.

Es hat sich weiterhin gezeigt, dass eine Anordnung eines Dämpfungselement zwischen Gleitelement und Träger vorteilhaft sein kann, wobei das Dämpfungselement die durch die Bewegung der Ski eingebrachten Schwingungen dämpft.It has also been found that an arrangement of a damping element between the sliding element and the carrier can be advantageous, wherein the damping element dampens the vibrations introduced by the movement of the skis.

Gemäß einer bevorzugten Ausführungsform weist der Träger des Gleitflächenelements definierte Schwachstellen auf, die im Bedarfsfall zur Erzeugung von Aufnahmeöffnungen für das Gleitelement dienen. Diese Schwachstellen sind vorteilhafterweise gitterförmig über den Träger angeordnet. Je nach Einsatzzweck des Gleitflächenelementes werden einzelne oder alle Schwachstellen des Trägers durchbrochen, so dass die am Träger angeordneten Befestigungsvorrichtungen freigelegt werden und die Gleitelemente mit dem Träger verbunden werden können.According to a preferred embodiment, the carrier of the Gleitflächenelements defined vulnerabilities, which serve in case of need to produce receiving openings for the sliding member. These weak points are advantageously arranged in a grid shape over the carrier. Depending on the intended use of the Gleitflächenelementes single or all weak points of the carrier are broken, so that the arranged on the carrier fastening devices are exposed and the sliding elements can be connected to the carrier.

Als einfache und kostengünstige Möglichkeit, die Verbindung zwischen Träger und Gleitelement herzustellen, hat sich eine Rast- und/oder eine Schraub- und/oder eine Dreh-Rastverbindung erwiesen.As a simple and cost-effective way to make the connection between the carrier and the sliding element, a latching and / or a screw and / or a rotary locking connection has been found.

Um nicht verwendete Befestigungsvorrichtungen vor Verschmutzung zu schützen, hat es sich vorteilhaft gezeigt, die jeweilige Befestigungsvorrichtung durch ein lösbar mit dem Träger verbundenes Verschlusselement abzudecken. Somit kann auch wirkungsvoll verhindert werden, dass das Wasser zum Kühlen der Gleitelemente in die Befestigungsvorrichtung und/oder den Träger eindringt. Es hat sich dabei auch gezeigt, dass zwischen das Verschlusselement und den Träger ein Dichtelement zur besseren Abdichtung vorteilhaft sein kann.In order to protect unused fasteners against contamination, it has been found advantageous to cover the respective fastening device by a releasably connected to the carrier closure element. Thus, it can also be effectively prevented that the water for cooling the sliding elements penetrates into the fastening device and / or the carrier. It has also been found that between the closure element and the carrier, a sealing element for better sealing can be advantageous.

Das Verschlusselement steht im Vergleich zu dem Gleitelement weniger über den Träger über, weist also eine geringere Höhe als das Gleitelement auf, so dass eine Berührung des auf dem Gleitelement aufliegenden Skis mit dem Verschlusselement vermieden ist.The closure element is compared with the slider less over the carrier over, so has a lower height than the sliding member, so that contact of the resting on the sliding ski with the closure element is avoided.

Für die Aufbringung des zur Kühlung verwendeten Wassers hat es sich als günstig erwiesen, Bewässerungselemente anzuordnen. Diese sind vorteilhafterweise ebenfalls lösbar mit dem Träger verbunden. Die Bewässerungselemente sind an Wasserleitungen angeschlossen, die auf der Rückseite des Trägers angeordnet sind.For the application of the water used for cooling, it has proven to be advantageous to arrange irrigation elements. These are advantageously also releasably connected to the carrier. The irrigation elements are connected to water pipes, which are arranged on the back of the carrier.

Auch das Bewässerungselement ist so gestaltet, dass eine Berührung mit dem Ski vermieden ist.The irrigation element is designed so that contact with the ski is avoided.

Das Verschlusselement und auch das Bewässerungselement können durch eine Rast- und/oder Schraub- und/oder Dreh-Rastverbindung mit dem Träger verbunden werden.The closure element and the irrigation element can be connected by a latching and / or screw and / or rotary locking connection with the carrier.

Gemäß einer weiteren Ausführungsform der Erfindung ist das Bewässerungselement derart gestaltet, dass die dem Ski zugewandte Oberfläche ähnlich der des Gleitelementes ausgebildet ist, so dass der Ski auch auf dem Bewässerungselement aufliegt.According to a further embodiment of the invention, the irrigation element is designed such that the surface facing the ski is similar to that of the sliding element, so that the ski also rests on the irrigation element.

In Figur 1 ist die Draufsicht auf ein erfindungsgemäßes Gleitflächenelement (10) dargestellt. Dieses weist einen rechteckigen Träger (1) auf, der über ein Verbindungselement (2) mit einem weiteren Träger (1) verbunden werden kann, so dass durch weitere Aneinanderreihung von Trägern (1) eine Auflagespur für Skier entsteht. Mit dem Träger (1) sind mehrere Gleitelemente (6) lösbar mittels Befestigungsvorrichtungen (5) verbunden. Das Gleitflächenelement (10) kommt insbesondere bei der Ausrüstung künstlicher Skianlagen zum Einsatz.In FIG. 1 the plan view of an inventive sliding surface element (10) is shown. This has a rectangular support (1), which can be connected via a connecting element (2) with another support (1), so that by further juxtaposition of carriers (1) creates a support track for skis. With the carrier (1) a plurality of sliding elements (6) are releasably connected by means of fastening devices (5). The sliding surface element (10) is used in particular when equipping artificial ski installations.

Weiterhin sind in der Figur 1 die Positionen von Schwachstellen (3) eingezeichnet. Diese sind in diesem Ausführungsbeispiel in Dreierreihen über die Längsrichtung des Trägers (1) in dem Träger (1) angeordnet. Es sind aber auch andere Anordnungen denkbar.Furthermore, in the FIG. 1 the positions of vulnerabilities (3) are drawn. These are arranged in this embodiment in rows of three over the longitudinal direction of the carrier (1) in the carrier (1). But there are also other arrangements conceivable.

Ein Querschnitt entlang der Linie A-A durch den in Figur 1 dargestelltes Gleitflächenelement (10) ist in Figur 2 dargestellt. Der Träger (1) des Gleitflächenelements (10) besteht in diesem Ausführungsbeispiel aus einem Kunststoffblasteil, das in mehrere Kammern (4) unterteilt ist. Weiterhin sind in diesem Beispiel Befestigungsvorrichtungen (5) des Trägers (1) für Gleitelemente (6) als einfache Ausnehmungen im Träger (1) ausgebildet. Die Gleitelemente (6), die an diesem Träger (1) lösbar mittels der Befestigungsvorrichtungen (5) verbunden werden, weisen Clipselemente auf, die auf der Rückseite des Trägers (1) in den Ausnehmungen verrasten. Damit wird eine Rastverbindung zwischen Träger (1) und Gleitelement (6) ausgebildet.A cross section along the line AA through the in FIG. 1 shown sliding surface element (10) is in FIG. 2 shown. The carrier (1) of the Gleitflächenelements (10) consists in this embodiment of a Kunststoffblasteil, which is divided into a plurality of chambers (4). Furthermore, fastening devices (5) of the carrier (1) for sliding elements (6) are designed as simple recesses in the carrier (1) in this example. The sliding elements (6), which are detachably connected to this carrier (1) by means of the fastening devices (5), have clip elements which latch into the recesses on the rear side of the carrier (1). Thus, a latching connection between the carrier (1) and sliding element (6) is formed.

Der Träger (1) ist vor dem ersten Einsatz derart ausgebildet, dass zunächst verschlossene Öffnungen (7) für die Befestigung der Gleitelemente (6) vorgesehen sind. Der Träger (1) weist an diesen Stellen Schwachstellen auf, die je nach Bedarf eine Freilegung der Öffnungen (7) und damit einen Zugang zu den entsprechenden Befestigungsvorrichtungen (5) ermöglichen.The carrier (1) is designed prior to the first use such that initially closed openings (7) are provided for the attachment of the sliding elements (6). The carrier (1) has at these points weak points, which allow, as needed, an exposure of the openings (7) and thus access to the corresponding fastening devices (5).

Durch die mögliche Veränderung der Gleitelementanzahl und/oder Gleitelementanordnung kann es vorkommen, dass Befestigungsvorrichtungen (5) nicht mehr mit Gleitelementen (6) bestückt sein müssen. Um ein Eindringen von Wasser, das zum Kühlen der Ski und des Gleitflächenelementes, insbesondere der Gleitelemente (6), benötigt wird, in den Träger (1) oder hinter den Träger (1) zu verhindern, ist ein Verschließen der einmal geöffneten Schwachstellen durch Verschlusselemente möglich. Diese stehen weniger über den Träger (1) über als die in der Umgebung des Verschlusselements angeordneten Gleitelemente (6). Somit wird eine Berührung zwischen Ski und Verschlusselement vermieden.Due to the possible change in the number of sliding elements and / or sliding element arrangement, it may happen that fastening devices (5) no longer have to be equipped with sliding elements (6). In order to prevent ingress of water, which is required for cooling the skis and the sliding surface element, in particular the sliding elements (6), into the carrier (1) or behind the carrier (1), closure of the once opened weak points by closure elements possible. These are less on the carrier (1) over than arranged in the vicinity of the closure element sliding elements (6). Thus, a contact between the ski and closure element is avoided.

Für die Aufbringung des Kühlwassers auf das Gleitflächenelement können in die Öffnungen (7) auch Bewässerungselemente eingesetzt werden. Diese können mit unterhalb des Trägers (1) angeordneten, nicht dargestellten Wasserleitungen verbunden werden.For the application of the cooling water on the Gleitflächenelement irrigating elements can be used in the openings (7). These can be connected to below the support (1) arranged, not shown, water pipes.

in Figur 3 ist ein weiteres Ausführungsbeispiel für einen Träger (1) eines Gleitflächenelementes (10) dargestellt. Dieses besteht aus einer aus Vollmaterial bestehenden Platte, die aus Kunststoff, Holz, Metall, Keramik oder Glas bestehen kann.in FIG. 3 is a further embodiment of a carrier (1) of a Gleitflächenelementes (10) shown. This consists of a solid material plate, which may consist of plastic, wood, metal, ceramic or glass.

Um eine bessere Abdichtung zwischen dem Träger (1) und dem Gleitelement (6) und/oder dem Verschlusselement und/oder dem Bewässerungselement zu erreichen, ist in diesem Ausführungsbeispiel ein Dichtelement (8) zwischen dem Träger (1) und dem Gleitelement (6) angeordnet.In order to achieve a better sealing between the carrier (1) and the sliding element (6) and / or the closure element and / or the irrigation element, in this embodiment a sealing element (8) is arranged between the carrier (1) and the sliding element (6). arranged.

Es ist in diesem Zusammenhang auch möglich, ein Dämpfungselement zwischen Träger (1) und Gleitelement (6) anzuordnen, so dass eine Geräuschreduzierung erreicht werden kann.It is also possible in this context to arrange a damping element between carrier (1) and sliding element (6), so that a noise reduction can be achieved.

Auch eine kombinierte Ausbildung als Dämpfungs- und Dichtelement ist möglich.A combined training as damping and sealing element is possible.

In Figur 4 ist ein Gleitelement (6) im Schnitt dargestellt. Dieses ist noppenförmig ausgebildet, wobei es in der Draufsicht sowohl rund als auch oval gestaltet sein kann. Diese Noppe (6) weist drei Verrastelemente (9) auf, mit denen die lösbare Verbindung zwischen Träger (1) und Gleitelement (6) herstellbar ist. Das Lösen des Gleitelementes (6) vom Träger (1) kann mit Hilfe eines geeigneten Hebels, wie zum Beispiel eines Schraubendrehers, erfolgen.In FIG. 4 a sliding element (6) is shown in section. This is designed knob-shaped, it may be designed both round and oval in plan view. This nub (6) has three latching elements (9), with which the releasable connection between the carrier (1) and sliding element (6) can be produced. The release of the sliding element (6) from the carrier (1) can take place with the aid of a suitable lever, such as a screwdriver.

Es liegt auch im Rahmen der Erfindung andere Gestaltungen des Gleitelementes (6), wie Quader, Zylinder, Pyramide, Pyramidenstumpf, Walze oder Kugel mit dem Träger (1) lösbar zu verbinden. Damit ergeben sich auch unterschiedliche Berührungsgeometrien zwischen Ski und Gleitelement (6). Diese können punkt-, linien-, rechteck-, rund- oder oval ausgebildet sein. Es ist auch eine beliebige Berührungsfläche zwischen Gleitelement (6) und Ski möglich.It is also within the scope of the invention, other configurations of the sliding element (6), such as cuboid, cylinder, pyramid, truncated pyramid, roller or ball to the carrier (1) releasably connect. This also results in different contact geometries between ski and sliding element (6). These can be point, line, rectangular, round or oval. It is also possible any contact surface between the sliding element (6) and ski possible.

Durch die unterschiedlichen Gleitelementgeometrien lassen sich die Gleiteigenschaften des Skis auf den Gleitelementen (6) variieren. Auch durch den Einsatz von Gleitelementen (6) aus verschiedenen Materialien ist eine Veränderung der Gleiteigenschaften möglich. Dies kann durch die lösbare Verbindung zwischen Träger (1) und Gleitelement (6) auch in unterschiedlichen Bereichen der Skianlage realisiert werden.Due to the different sliding element geometries, the sliding properties of the ski on the sliding elements (6) can be varied. Also by the use of sliding elements (6) made of different materials, a change in the sliding properties is possible. This can be realized by the detachable connection between the carrier (1) and sliding element (6) in different areas of the ski system.

Zudem ist eine Simulation unterschiedlicher Gleitbedingungen mit den lösbaren Gleitelementen (6) möglich.In addition, a simulation of different sliding conditions with the releasable sliding elements (6) is possible.

Es können für die lösbare Verbindung zwischen Träger (1) und Gleitelement (6) auch andere an sich bekannte Verbindungsarten, wie Schraub- oder Dreh-Rastverbindungen verwendet werden.It can be used for the detachable connection between the carrier (1) and sliding element (6) also known per se connection types, such as screw or rotary locking connections.
