Description

Die vorstehende Erfindung betrifft ein Geraet zur Erzeugung einer Langlaufloipe gemaess der Einleitung des Anspruchs 1.The above invention relates to a device for generating a cross-country ski run according to the preamble of claim 1.

Schlittenartige Geraete zur Erzeugung einer Langlaufloipe stellen bekannterweise ein am Schneefahrzeug anhaengbares Zusatzgeraet dar, das ueblicherweise nach einer Vorrichtung zur Aufbereitung und Glaettung des Schneefeldes angeordnet ist. Bei den bekannten Schlitten zur Erzeugung einer Langlaufloipe sind an der Unterseite des Geraetes Kufen zur Herstellung der Spur angeordnet, diese Kufen sind parallel zur Zugrichtung des Schneefahrzeuges angeordnet und erzeugen parallel Spuren, die mit gleichem, gegenseitigen Abstand ueber die gesamte Laenge der Langlaufloipe angeordnet sind.Sledge-like devices for producing a cross-country ski run are known to represent an additional device which can be attached to the snow vehicle and which is usually arranged after a device for processing and smoothing the snow field. In the known sledges for producing a cross-country ski run, runners for producing the track are arranged on the underside of the device, these runners are arranged parallel to the direction of pull of the snow vehicle and produce parallel tracks which are arranged at the same mutual distance over the entire length of the cross-country ski run.

Es hat sich herausgestellt, dass weniger geuebte oder unerfahrene Langlaeufer beim Befahren von abwaerts geneigten Haengen, bei welchen groessere Stabilitaet und hoeheres Fahrkoennen des Langlaeufers erforderlich sind, eine groessere Sicherheit dann erreichen, wenn ein Auseinaderspreitzen der Langlaufski durch teilweises Verlassen der Loipenspur erreicht wird. Dies fuehrt jedoch haeufig zu Gleichgewichtsverlagerung und Stuerzen, mit der Gefahr einer Koerperverletzung.It has been found that less experienced or inexperienced cross-country skiers when driving downhill inclined slopes, where greater stability and higher driving ability of the cross-country skier are required, achieve greater safety if the cross-country skis are spread apart by partially leaving the track. However, this often leads to balance shift and falls, with the risk of physical injury.

Nach Ueberwinden der abschuessigen Loipenstrecke muessen die Langlaeufer erneut mit dem Langlaufski in die vorher verlassene Spur der Loipe eintreten. Auch dieser Moment stellt eine kritische Bewegungsfase dar und kann zu Stuerzen fuehren. Es ist ferner bekannt, dass bei sportlichen Wettkaempfen der Abstand zwischen den Spuren der Loipe nicht genormt ist, sondern von Fall zu Fall vom Veranstalter vor Beginn des Wettkampfes festgelegt wird. Aufgabe der vorstehenden Erfindung ist es, eine Einrichtung zum Herstellen einer Loipenspur zu schaffen, bei der es dem Fahrer des Schneefahrzeuges moeglich ist, rasch den Abstand zwischen den Spuren waehrend der Herstellung der Langlaufloipe zu aendern.After overcoming the sloping trail, the cross-country skiers have to enter the previously left track on the cross-country ski again. This moment also represents a critical phase of movement and can lead to falls. It is also known that in sports competitions the distance between the tracks on the trail is not standardized, but is determined on a case by case basis by the organizer before the start of the competition. The object of the above invention is to create a device for producing a cross-country track in which the driver of the snow vehicle is able to quickly change the distance between the tracks during the production of the cross-country ski track.

Bei einem Spurgeraet der eingangs genannten Art wird diese Aufgabe dadurch geloest, dass die Spurkufen im Schlitten quer zur Bewegung des Geraetes verschiebbar angeordnet sind und dazu steuerbare Antriebsvorrichtungen Einsatz finden. Es wird eine einfache konstruktive Loesung fuer die Spurkufen und die Fuehrung der Spurkufen dadurch erreicht, dass jede Kufe an ihrer Oberseite eine portalartige Halterung aufweist, deren stehende Saeulen in schlitzartige Fuehrungen der Schlittenplatte ragen, und diese Fuehrungsschlitze quer zur Fahrrichtung des Schlittens angeordnet sind, wobei dem querliegenden Joch des Portals eine steuerbare Antriebsvorrichtung zugeordnet ist.In the case of a track device of the type mentioned at the outset, this object is achieved in that the track runners are arranged in the carriage so as to be displaceable transversely to the movement of the device, and controllable drive devices are used for this purpose. It will be a simple constructive solution for the Track skids and the guidance of the track skids are achieved in that each skid has a portal-like holder on its top, the standing columns of which protrude into slot-like guides of the slide plate, and these guide slots are arranged transversely to the direction of travel of the slide, the controllable drive device for the transverse yoke of the portal assigned.

Es wird eine einfache Verschiebevorrichtung der Kufen zur Bildung der Langlaufloipe mit geringem Platzbedarf fuer die Antriebsvorrichtungen und einfachen Mitteln fuer die Energiezufuehrung vom Schneefahrzeug dadurch erreicht, dass die steuerbaren Antriebsvorrichtungen der Kufen aus einer hydraulischen Kolbenzylindereinheit bestehen.A simple shifting device of the runners for forming the cross-country ski track with a small space requirement for the drive devices and simple means for supplying energy from the snow vehicle is achieved in that the controllable drive devices of the runners consist of a hydraulic piston-cylinder unit.

In einer weiteren Ausfuehrungsform ist es moeglich, die Anzahl der Antriebsvorrichtungen fuer die verstellbaren Kufen dadurch zu vermindern, dass auf dem Schlitten zwischen zwei Loipenkufen eine Kolbenzylindereinheit mit sich gegenueberliegenden Kolbenstangen vorgesehen ist, und jede dieser Kolbenstangen mit einer portalartigen Halterung der Loipenkufen verbunden ist.In a further embodiment, it is possible to reduce the number of drive devices for the adjustable runners in that a piston-cylinder unit with opposing piston rods is provided on the slide between two cross-country runners, and each of these piston rods is connected to a portal-like holder for the cross-country runners.

Es ist moeglich, mehrere Abstaende zwischen den Loipenspuren dadurch einzustellen, dass den Loipenkufen Kolbenzylindereinheiten zugeordnet sind, die unterschiedliche Huebe ausfuehren.It is possible to set several distances between the cross-country tracks by assigning piston-cylinder units to the cross-country runners that perform different strokes.

Es wird eine einfache Bauart fuer die Kufen sowie eine rasche Montage und sichere Fuehrung der Kufen in den schlitzartigen Fuehrungen des Schlittens dadurch erzielt, dass die portalartige Halterung der Kufen aus zwei Saeulen mit kreisrundem Querschnitt und einem dazugehoerenden Verbindungsjoch bestehen.It will be a simple design for the runners as well as one rapid assembly and safe guiding of the runners in the slot-like guides of the sled is achieved in that the portal-like mounting of the runners consists of two columns with a circular cross-section and an associated connecting yoke.

Ein rasches Steuern zum Veraendern des gegenseitigen Abstandes der Loipenkufen durch den Fahrer des Schneefahrzeuges wird dadurch moeglich, dass die Betaetigungseinrichtungen fuer die Antriebsvorrichtungen der Kufen in der Fahrerkabine vorgesehen sind.Rapid control by the driver of the snow vehicle for changing the mutual distance between the cross-country runners is made possible by the fact that the actuating devices for the drive devices of the runners are provided in the driver's cabin.

Der wesentliche Vorteil, der mit dem erfindungsgemaessen Spurgeraet erzielbar ist, besteht darin, dass der Abstand zwischen den Loipenspuren zu Beginn der Loipe, entsprechend den Richtlinien des Wettkampfveranstalters, automatisch eingestellt werden oder aber waehrend der Fahrt des Schneefahrzeuges bei Loipen, die nicht zu Wettkampfzwecken dienen, einstellbar ist, ohne dabei den Fahrer des Schneefahrzeuges von der erforderlichen Aufmerksamkeit zum Bedienen und Lenken des Fahrzeuges und ohne unerwuenschte Totzeiten, zu ermoeglichen.The main advantage that can be achieved with the track device according to the invention is that the distance between the track tracks at the start of the track is set automatically in accordance with the guidelines of the competition organizer, or while the snow vehicle is traveling on tracks that are not used for competition purposes , is adjustable without allowing the driver of the snow vehicle the necessary attention to operate and steer the vehicle and without undesired dead times.

Die Ruestzeiten fuer die Herstellung der Langlaufloipe werden nicht verlaengert, da es nicht mehr notwendig ist, das Schneefahrzeug dafuer anzuhalten. Aus diesem Grund kann der Fahrer des Schneefahrzeuges fuer jeden Bedarfsfall die Spuren der Loipe (z.B. bei abschuessigem Gelaende oder bei schwierig befahrbarer Loipe) verbreitern, ohne dafuer wertvolle Zeit zu verlieren und ohne die Fahrerkabine des Schneefahrzeuges verlassen zu muessen. Das Verstellen der Loipenkufen erfolgt in einfacher Weise durch Betaetigen von Schaltern oder aehnlichen Einrichtungen, die in gut erreichbarer Lage im Fahrerhaus angeordnet sind.The set-up times for the production of the cross-country ski run are not extended, since it is no longer necessary to stop the snow vehicle for it. For this reason, the driver of the snow vehicle can trace the trail for every need (for example on sloping terrain or at difficult cross-country ski trail) without wasting valuable time and without having to leave the driver's cabin of the snow vehicle. The cross-country runners can be adjusted in a simple manner by operating switches or similar devices which are arranged in an easily accessible position in the driver's cab.

Die einfache Bauform und Zuverlaessigkeit des Antriebes fuer die Spurkufen, der keinen Eingriff von Hand erfordert, stellt einen weiteren Vorteil der Erfindung dar.The simple design and reliability of the drive for the track skids, which does not require manual intervention, represents a further advantage of the invention.

Weitere Merkmale, Vorteile und Einzelheiten der Einrichtung zur Herstellung einer Loipenspur koennen der nun folgenden Beschreibung, unter Bezugnahme auf die beigefuegten Zeichnungen, entnommen werden.Further features, advantages and details of the device for producing a cross-country track can be found in the following description, with reference to the accompanying drawings.

In den Zeichnungen wird ein bevorzugtes Ausfuehrungsbeispiel schematisch dargestellt.A preferred exemplary embodiment is shown schematically in the drawings.

Es zeigen:

  • Fig. 1 eine Ansicht in Perspektive einer Einrichtung zur Herstellung einer Loipenspur; und
  • Fig. 2 eine Draufsicht auf das Geraet gemaess Fig. 1 mit zwei unterschiedlichen Lagen der Kufen zur Erzeugung von drei unterschliedlichen Spurbreiten.
Show it:
  • 1 is a perspective view of a device for producing a cross-country track; and
  • Fig. 2 is a plan view of the device according to Fig. 1 with two different positions of the runners to produce three different track widths.

Der Schitten 1 zur Herstellung der Langlaufloipe weist eine Platte 2 mit zwei Kufen 3 zur Erstellung der Spur auf.The slide 1 for producing the cross-country ski trail has a plate 2 with two runners 3 for creating the track.

Aus Gruenden der Einfachheit wurden die Zugmittel oder Anhaengemittel am Schneefahrzeug nicht dargestellt.For the sake of simplicity, the traction means or attachment means on the snow vehicle have not been shown.

Entsprechend der Erfindung sind die Kufen 3 zur Herstellung der Spur quer zur Bewegungsrichtung F des Schlittens steuerbar verschiebbar angeordnet. Zu diesem Zweck sind im dargestellten Beispiel in die Schlittenplatte 2 Fuehrungsschlitze 5, die quer zur Vorschubrichtung des Schlittens angeordnet sind, und in Fig. 1 dargestellt sind, eingearbeitet.According to the invention, the runners 3 for producing the track are arranged so as to be controllably displaceable transversely to the direction of movement F of the slide. For this purpose, in the example shown in the slide plate 2 guide slots 5, which are arranged transversely to the feed direction of the slide and are shown in Fig. 1, are incorporated.

An der Oberseite der Kufen 3 ist eine portalartige Halterung 6 befestigt, die aus zwei Saeulen 7 und einem Joch 8 besteht. Die Saeulen 7, die in vorteilhafter Weise als Saeulen mit Kreisquerschnitt ausgebildet sind, durchdringen die Ausnehmungen 5 und sind an den Kufen, z.B. mittels Schrauben, durch Schweissverbindung oder in anderer, geeigneter Weise befestigt.On the top of the runners 3, a portal-like holder 6 is attached, which consists of two columns 7 and a yoke 8. The columns 7, which are advantageously designed as columns with a circular cross section, penetrate the recesses 5 and are on the runners, e.g. attached by means of screws, by welding or in another suitable manner.

In der Mitte des Joches 8 ist im Punkt 9 z.B. unter Verwendung einer Gewindehuelse oder einer Befestigungsgabel mit durchgehendem Bolzen, die Kolbenstange 10 einer Kolbenzylinderheinheit 11 befestigt, die auf der Schlittenplatte 2 angeordnet ist.In the middle of the yoke 8, e.g. using a threaded sleeve or a fastening fork with a continuous bolt, the piston rod 10 is attached to a piston-cylinder unit 11 which is arranged on the slide plate 2.

Die Kolbenzylindereinheiten 11 sind in vorteilhafter Weise als Hydraulikgruppen ausgebildet und werden von einer Pumpe, die vom Motor des Schneefahrzeuges angetrieben wird, ueber flexible Leitungen mit Druckmittel beaufschlagt. Die Betaetigungsmittel fuer die Kolbenzylindereinheiten 11 sind in vorteilhafter Weise im Fahrerhaus vorgesehen.The piston-cylinder units 11 are advantageously designed as hydraulic groups and are acted upon by a pump, which is driven by the engine of the snow vehicle, via flexible lines with pressure medium. The actuating means for the piston-cylinder units 11 are advantageously provided in the cab.

Die Kolbenzylindereinheiten 11 koennen mit konstantem Hub arbeiten. Ist dieser Hub kleiner als die Laenge der Schlitze 5, so kann in vorteilhafter Weise auf die Vorsehung von Endschaltern verzichtet werden, Bauteile, die den Bauaufwand nur vergroessern wuerden.The piston-cylinder units 11 can work with a constant stroke. If this stroke is smaller than the length of the slots 5, it is advantageously possible to dispense with the provision of limit switches, components which would only increase the construction effort.

Die Kolbenzylindereinheiten 11 koennen auch so ausgefuehrt sein, dass unterschiedliche Hubbewegungen durchfuehrbar sind, d.h., die Hubbewegungen koennen differenzierte Werte haben. Es ist somit moeglich, eine groessere Anzahl unterschiedlicher Abstaende zwischen den Spuren der Loipe vorzusehen.The piston-cylinder units 11 can also be designed so that different stroke movements can be carried out, i.e. the stroke movements can have different values. It is therefore possible to provide a larger number of different distances between the tracks on the trail.

Der Fig. 2 kann entnommen werden, dass mit den Kufen 3 in zusammengefahrener Stellung, parallel zueinander angeordnete Spuren 12, 13 mit einem Abstand (a) herstellbar sind. Wird ein Einfahren der Kolbenstange 10 eingeleitet, d.h. wird die entsprechende Kufe 3 nach aussen verschoben, so wird eine Spur mit groesser werdendem Abstand, d.h. eine Spur mit dem Abstand (b) erstellt.It can be seen from FIG. 2 that with the runners 3 in the moved-together position, tracks 12, 13 arranged parallel to one another can be produced at a distance (a). If the piston rod 10 is retracted, i.e. If the corresponding runner 3 is moved outwards, a track with increasing distance, i.e. creates a track with the distance (b).

Der Fig. 2 kann ferner entnommen werden, dass bei Verfahren einer einzigen Kufe, z.B. der rechten Kufe 3, in die eingefahrene Stellung, eine Spur mit einem Zwischenabstand (c) erstellt ist.It can also be seen from Fig. 2 that in the case of methods of a single runner, e.g. the right runner 3, in the retracted position, a track with an intermediate distance (c) is created.

Durch den Einsatz von Kolbenzylindereinheiten 11 mit differenziertem Hub kann eine weitaus groessere Anzahl gegenseitiger Abstaender (a, b, c) zwischen den Spuren erzeugt werden.By using piston-cylinder units 11 with a differentiated stroke, a much larger number of mutual spacers (a, b, c) can be found between the tracks be generated.

Es ist Bestandteil der vorstehenden Erfindung, die Kolbenzylindereinheiten 11 durch technisch gleichwertige Vorrichtungen z.B. elektrische Motoren oder Hebeleinrichtungen zu ersetzen.It is part of the above invention, the piston-cylinder units 11 by technically equivalent devices e.g. to replace electric motors or lever devices.

Ferner kann eine Kolbenzylindereinheit mit zwei differenziert betaetigbaren Kolbenstangen, die auf der Platte 2 zwischen den Kufen 3 angeordnet ist, vorgesehen sein.Furthermore, a piston-cylinder unit with two differentially operable piston rods, which is arranged on the plate 2 between the runners 3, can be provided.

Jede Kolbenstange ist in diesem Fall mit einem Joch der dazugehoerigen Kufe, die in Fig. 2 mit Strichpunktlinien dargestellt sind, verbunden. Auch die Ausfuehrung des Jochs 6 kann von der dargestellten Bauform abweichen, z.B. kann eine einstueckige Vorrichtung vorgesehen werden.In this case, each piston rod is connected to a yoke of the associated runners, which are shown in broken lines in FIG. 2. The design of the yoke 6 can also differ from the design shown, e.g. a one-piece device can be provided.
