Description

Die vorstehende Erfindung betrifft eine Vorrichtung zum Erzeugen . einer Langlaufloipe.The above invention relates to a device for generating. a cross-country ski run.

Es sind bereits verschiedene Vorrichtungen zum Erzeugen einer Langlaufloipe bekannt geworden. Diese bekannten Geraete bestehen hauptsaechlich aus einem ziehbaren Schlitten, wobei dieser Schlitten auf der dem Schneefeld zugekehrten Seite, fest angeordnete Kufen aufweist, mit denen in die Schneedecke die Vertiefungen fuer die Langlaufloipe eingepraegt werden, die spaeter mit den Langlaufskiern befahren wird.Various devices for generating a cross-country ski run have already become known. These known devices mainly consist of a pullable sled, this sled having fixedly arranged runners on the side facing the snow field, with which the depressions for the cross-country ski run are stamped into the snow cover, which are later used on the cross-country skis.

Die bei den bekannten Geraeten vorgesehenen Kufen sind fest angeordnet, und es besteht keine Moeglichkeit, diese Kufen ausser Kontakt mit dem Schneefeld zu bringen. Dies bringt den schwerwiegenden Nachteil mit sich, dass die empfindlichen Laufflaechen der Kufen beschaedigt werden, wenn z.B. ein nicht verschneites Feld zu ueberqueren ist, z. B. Strassen, Wege oder Felsenfelder.The runners provided in the known devices are fixed and there is no possibility of bringing these runners out of contact with the snow field. This has the serious disadvantage that the sensitive running surfaces of the runners are damaged if e.g. a field that is not covered with snow is to be crossed, e.g. B. roads, paths or rock fields.

Ein weiterer Nachteil der bekannten Vorrichtung, die mit fest angeerdneten Kufen versehen ist, ist dirin zu sehen, dass mit diesem Geraet die Vertiefungen der Langlaufloipe auch bei Bergabfahrt, Bergauffahrt oder Kurvenfahrt in den Schnee eingepraegt werden. Diese Tatsache stellt bekannterweise eine sehr grosse Gefahrenquelle fuer den Langlaeufer dar, besonders, wenn dieser nicht ueber eine groessere Langlauferfahrung verfuegt, dies aufgrund der Tatsache, dass die ausgepraegten und oft vereisten Spuren der Langlaufloipe bei Bergabfahrt, Berauffahrt oder Kurvenfahrt die freie und unbehinderte Fahrt des Langlaeufers einschraenken.Besonders bei Bergauffahrt erschweren die oft vereisten Spuren der Langlaufloipe den Anstieg, der meist unter Verwendung der Fischgraettechnik (V-foermiges Auseinanderspreitzen der Skier beim Anstieg) erfolgt. Es ist eine weitere Vorrichtung zum Erstellen von Lauglaufloipen bekannt geworden, die aus zwei gelenkig miteinander verbundenen Schlitten besteht, wobei der erste Schlitten zum Aufrauhen und Auflockern des oft verharschten Schneefeldes dient, und der zweiter Schlitten fest angeordenten Gleitkufen aufweist. Auch in diesem Falle, bleibt der die Gleitkufen aufweisende Schlitten stets in Beruehrung mit dem Schneefeld und deshalb treten die bereits erlaeuterten Nachteile auch bei dieser Vorrichtung auf.Another disadvantage of the known device, which is provided with firmly grounded runners, can be seen that with this device, the depressions of the cross-country ski trail can also be engraved in the snow when driving downhill, uphill or cornering. This fact is known to represent a very great source of danger for the cross-country skier, especially if he does not have a greater cross-country experience, due to the fact that the pronounced and often icy traces of the cross-country ski trail on downhill, uphill or cornering the free and unimpeded travel of the The often icy traces of the cross-country ski trail make it difficult to climb, especially when driving uphill, which is usually done using fish-grill technology (V-shaped spreading apart of the skis during the climb). A further device for creating cross-country ski trails has become known, which consists of two articulated sledges, the first sled used to roughen and loosen up the often heaped snow field, and the second sled has fixedly arranged skids. In this case too, the slide with the skids always remains in contact with the snow field and therefore the disadvantages already explained also occur with this device.

Aufgabe der vorstehenden Erfindung ist es ein Geraet zur Erstellung einer Langlaufloipe vorzuschlagen, das z. B. von einer Pistenaufbereitungsmaschine oder einem aehnlichen Zugmittel gezogen werden kann, und mit welchen Geraet die den bekannten Vorrichtungen dieser Art anhaftenden Nachteile mit Sicherheit vermieden werden, und die Erstellung einwandfreier Langlaufloipen ermoeglicht. Es ist weiterhin Aufgabe des Erlindungsgegenstandes, ein Geraet zur Erstellung von Langlaufloipen vorzuschlagen, mit dem es moeglich ist, die Kufen zur Herstellung der Loipenvertiefungen automatisch und schnell ausser Kontakt mit dem Schneefeld zu bringen, bzw. die Kufen automatisch und schnell in die gewuenschte Arbeitsstellung zu bewegen.The object of the above invention is to propose a device for creating a cross-country ski run which, for. B. can be pulled by a piste preparation machine or a similar traction device, and with which equipment the known Devices of this type inherent disadvantages can be avoided with certainty, and the creation of perfect cross-country trails possible. It is also the task of the object of the invention to propose a device for creating cross-country trails with which it is possible to automatically and quickly bring the runners for making the cross-country trails out of contact with the snow field, or to automatically and quickly move the runners into the desired working position move.

Die erfindungsgemaesse Aufgabe wird dadurch erzielt, dass in einer, parallel zum Schneefeld angeordneten Ebene des ziehbaren Schlittens, Oeffnungen vorgesehen sind, denen parallel angeordnete Aufnahmemittel zugeordnet sind, die mindestens auf einer Seite Kufen zur Erstellung einer Langlaufloipe aufweisen, dass diese Aufnahmemittel drehbar gelagert sind, um von einer Arbeitsstellung , in der die Kufen zur Erstellung der Langlaufloipe von der Unterseite der Schlittenflaeche abstehen, in eine Ruheposition bringbar sind, in der die Kufen nicht in Beruehrung mit dem Schneefeld sind, und ferner die Laengsoeffnungen des Schlittens durch entsprechende Abschlussflaechen der Aufnahmemittel verschlossen sind.The object according to the invention is achieved in that openings are provided in a plane of the pullable sled which is arranged parallel to the snow field and to which parallel receiving means are assigned which have runners on at least one side for creating a cross-country ski run, that these receiving means are rotatably mounted, in order to be able to be brought from a working position in which the runners for creating the cross-country ski run protrude from the underside of the sled surface into a rest position in which the runners are not in contact with the snow field, and furthermore the longitudinal openings of the sled are closed by corresponding end surfaces of the receiving means are.

Wie der Fig. 1 zu entnehmen ist, besteht die erfindungsgemaesse Vorrichtung aus einem Schlitten 1, der als ebene Platte ausgebildet ist, die an ihrer Vorderseite eine leicht nach oben gewoelbte Wand 2 aufweist. Mit der Wand 2,steht ueber Gelenke 3 eine Deichsel 4 in Verbindung, die mit der Zugmaschine, in vorteilhafter Weise einem Pistenaufbereitungsgeraet oder einem anderen Schneefahrzeug, verbunden ist.As can be seen from FIG. 1, the device according to the invention consists of a slide 1 which is designed as a flat plate which has a slightly curved wall 2 on its front side. With the wall 2, a drawbar 4 is connected via joints 3, which is connected to the tractor, advantageously a piste preparation device or another snow vehicle.

In die Platte 5 des Schlittens 1 sind Oeffnungen 6 eingearbeitet, die parallel zueinander angeordnet sind, und sich in Laengsrichtung der Geraetes, in der mit dem Pfeil f dargestellten Vorwaertsbewegung, erstrecken. In der Naehe der vorderen, sowie der hinteren Abschlussseiten der Oeffnungen 6, sind in vorteilhafter Weise Drehlager 8 auf der Platte 5 vorgesehen, die um ihre Laengsachse verdrehbare Halte- und Aufnahmevorrichtungen 9 aufnehmen.Openings 6 are incorporated into the plate 5 of the carriage 1, which are arranged parallel to one another and extend in the longitudinal direction of the device, in the forward movement shown by the arrow f. Near the front, and the rear end sides of the openings 6, pivot bearings 8 are advantageously provided on the plate 5, which receive holding and receiving devices 9 which can be rotated about their longitudinal axis.

Die Halte- und Aufnahmevorrichtungen 9, die jede geeignete Form aufweisen koennen, weisen in vorteilhafter Weise dreieckigen Querschnitt auf, und sind besonders als Dreieck mit wenigstens zwei gleichen Seiten ausgebildet. In vorteilhafter Weise haben die den gleichen Seiten zugeordneten Flaechen des Aufnahme- und Haltemittels 9 ungefaehr die Abmessungen der Oeffnungen 6 der Platte 5 des Schlitten 1.The holding and receiving devices 9, which can have any suitable shape, advantageously have a triangular cross section, and are particularly designed as a triangle with at least two identical sides. Advantageously, the surfaces of the receiving and holding means 9 assigned to the same sides have approximately the dimensions of the openings 6 of the plate 5 of the slide 1.

An einem Ende weisen die Halte- und Aufnahmemittel 9 abstehende Laschen 10 auf, mit denen ueber geeignete Gelenke, Buegel 11 wirkverbunden sind, von denen der eine mit der Stange 12 und der ander mit dem Zylindermantel 13 eines Hydraulikzylinders wirkverbunden sind. Die Zylindereinheit wird in vorteilhafter Weise ueber Druckfluessigkeit gesteuert, die z. B. ueber Druckleitungen 14 von der zentralen Hydraulikeinheit der Zugmaschine versorgt werden. Selbstverstaendlich kann auch eine pneumatische oder elektrische Steuerung zum Einsatz gelangen.At one end, the holding and receiving means 9 have protruding tabs 10, with which brackets 11 are operatively connected via suitable joints, one of which is operatively connected to the rod 12 and the other to the cylinder jacket 13 of a hydraulic cylinder. The cylinder unit is controlled in an advantageous manner via pressure fluid, which, for. B. are supplied via pressure lines 14 from the central hydraulic unit of the tractor. Of course, a pneumatic or electrical control can also be used.

In vorteilhafter Weise, ist ueber den drehbaren Halte- und Aufnahmemitteln 9 ein Schutzgestell 15 angeordnet, in dessen Mitte von der Platte 5 des Schlittens 2 eine kleine Saeule 16 nach oben absteht. Auf dem Schutzgestell 15 sowie der Saeule 16 kann im Bedarfsfall ein nicht dargestelltes Gewicht, z.B. in Form eines Betonblockes angeordnet sein.In an advantageous manner, a protective frame 15 is arranged above the rotatable holding and receiving means 9, in the middle of which a small column 16 protrudes upward from the plate 5 of the carriage 2. If necessary, a weight, not shown, can be placed on the protective frame 15 and the column 16, for example in the form be arranged in a concrete block.

ln Fig. 2 ist die erfindungsgemaesse Vorrichtung schematisch in Arbeitsstellung dargestellt. In diesem Falle ist der Hydraulikzylinder 13 derartig durch das Druckmittel beaufschlagt, dass die Kolbenstange 12 aus dem Zylinder 13 ausgefahren wird. Ueber die senkrecht angeordneten Buegel 11, die mit dem Zylinder 13 und der Kolbenstange 12 verbunden sind, sowie ueber geeignete Gelenke, die mit den Laschen 10 der Halte-und Aufnahmemittel 9 wirkverbunden sind, wird eine derartige Drehbewegung hervorgerufen, dass die Kufen 17 zur Erstellung der Langlaufloipe sich in eine Stellung bewegt werde, in der sie zum Schneefeld 18 hin gerichtet sind, und dabei natuerlich die Oeffnungen 6 der Platte 5 des Schlittens 2 durchdringen und von der unteren Seite des Schlittens abstehen.2, the device according to the invention is shown schematically in the working position. In this case, the hydraulic cylinder 13 is acted upon by the pressure medium in such a way that the piston rod 12 is extended out of the cylinder 13. Via the vertically arranged brackets 11, which are connected to the cylinder 13 and the piston rod 12, and via suitable joints, which are operatively connected to the tabs 10 of the holding and receiving means 9, such a rotational movement is brought about that the runners 17 are used to create them the cross-country ski trail is moved into a position in which they are directed towards the snow field 18, and of course penetrate the openings 6 of the plate 5 of the slide 2 and protrude from the lower side of the slide.

In dieser Stellung sind die Kufen in ihrer Arbeitsstellung angeordnet und praegen daher, waehrend der Bewegung des Schlittens in Richtung des Pfeiles f die gewuenschten Vertiefungen der Langlaufloipe. 19 in das Schneefeld.In this position, the runners are arranged in their working position and therefore, during the movement of the slide in the direction of the arrow f, shape the desired depressions of the cross-country ski trail. 19 in the snow field.

- Wie hauptsaechlich der Fig. 1 zu entnehmen ist, erfolgt auf beiden Seiten der Vertiefungen 19 der Langlaufloipe ein vorteilhaftes Verdichten und Glaetten des Schneefeldes durch die Gleitflaeche des Schlittens 1. - As can be seen mainly of Figure 1, takes place on both sides of the recesses 19 of the cross-country ski, an advantageous compacting and smoothing the snow field through the sliding surface of the carriage 1..

Die Ruhestellung der Kufen 17 ist in der Fig. 3 dargestellt.The rest position of the runners 17 is shown in FIG. 3.

In diesem Falle wurde der Zylinder 13 mit seinem Kolben erneut durch das Druckmittel beaufschlagt (jedoch in entgegengesetzter Richtung), wodurch die Kolbenstange 12 vollstaendig in das Innere des Zylinders 13 eingefahren wird. Somit erfolgt eine Drehung der Halte- und Aufnahmemittel 9 um ihre Laengsachse, wie dies schematisch durch den Pfeil g dargesellt ist. In dieser Ruhestellung erfolgt durch die den Kufen 17 gegenueberliegende Flaeche eines jeden Halte- und Aufnahmemittels 9 ein nahezu vollstaendiger Abschluss der zugeordneten Oeffnung 6 des Schlittens 1, wodurch in vorteilhafter Weise vermieden wird, dass durch die Oeffnungen 6 Schnee dringen koennte, der sich in unerwuenschter Weise auf der Oberflaeche des Schlittens 1 ablegen koennte.In this case, the cylinder 13 was again charged with its piston by the pressure medium (but in the opposite direction Direction), whereby the piston rod 12 is completely retracted into the interior of the cylinder 13. The holding and receiving means 9 thus rotate about their longitudinal axis, as is shown schematically by the arrow g. In this rest position, the surface of each holding and receiving means 9 opposite the runners 17 results in an almost complete completion of the associated opening 6 of the slide 1, which advantageously prevents snow 6 from penetrating through the openings, which could be undesirable Could lay down on the surface of the carriage 1.

In der in Fig. 3 dargestellten Stellung, weist der Schlitten 1 eine Gerade und nicht durch Oeffnungen unterbrochene Unterseite auf; die Kufen 17 zur Erstellung der Langlaufloipe befinden sich hingegen nicht in Arbeitsstellung, sondern in ihrer Ruhestellung, in welcher die Kufen 17 vor Beschaedigung durch Strassen, Wege oder nicht verschneite Felsengebiete, geschuetzt sind.In the position shown in FIG. 3, the carriage 1 has a straight line and the underside which is not interrupted by openings; The runners 17 for creating the cross-country ski trail, however, are not in the working position, but in their rest position, in which the runners 17 are protected from damage by roads, paths or rocky areas not covered with snow.

Die Verdrehung der Kufen 17 in die Arbeitsstellung (Fig. 2) oder in die Ruhestellung (Fig. 3) kann automatisch z.B. von der Fahrerkabine des Pistenaufbereitungsgeraetes oder des Schneefahrzeuges gesteuert werden, zu diesem Zwecke genuegt es, in der Fahrerkabine einen geeigneten Steuerhebel vorzusehen, um in der gewuenschten Weise das Druckmittel ueber die Druckleitungen 14 zum Zylinder 13 zu foerdern.The rotation of the runners 17 in the working position (Fi g . 2) or in the rest position (Fig. 3) can be controlled automatically, for example, from the driver's cabin of the piste preparation device or the snow vehicle, for this purpose it is sufficient to provide a suitable control lever in the driver's cabin in order to convey the pressure medium via the pressure lines 14 to the cylinder 13 in the desired manner.

Aus den Fig. 1 - 3 kann entnommen werden, dass die Kolbenzylindereinheiten 12, 13 nur mit den drehbar angeordneten Halte- und Aufnahmemitteln 9 fliegend wirkverbunden sind. In vorteilhafter Weise sind keine weiteren Lager- und Haltemittel zur Aufnahme der Kolbenzylindereinheit 12,13 auf der Oberflaeche 5 des Schlittens 1 anzubringen. Diese Ausfuehrungsform ermoeglicht es, die Kolbenzylindereinheit 12,13 besonders funktionstuechtig und einfach in ihrem mechanischen Aufwand auszubilden.It can be seen from FIGS. 1-3 that the Piston-cylinder units 12, 13 are only operatively connected to the rotatably arranged holding and receiving means 9. Advantageously, no further storage and holding means for receiving the piston-cylinder unit 12, 13 are to be attached to the surface 5 of the slide 1. This embodiment enables the piston-cylinder unit 12, 13 to be designed to be particularly functional and simple in terms of its mechanical complexity.

Aus der Fig. 4 kann die Anordnung und Ausfuehrung der Oeffnungen 6 in der Ebene 5 des Schlittens 1, der nur teilsweise dargestellt ist, entnommen werden.The arrangement and design of the openings 6 in the plane 5 of the carriage 1, which is only partially shown, can be seen from FIG. 4.

Mit besonderem Vorteil stehen von den Enden der Halte- und Aufnahmemittel 9 Drehzapfen 9a ab, die von geeigneten Lagern 8, die fest auf der Oberflaeche des Schlittens 1 angeordnet sind, aufgenommen werden. In der Darstellung gemaess 4, befinden sich die Kufen 17 fuer die Erstellung der Langlaufloipe, in ihrer Arbeitsstellung. Der Fig. 4 kann ferner entnommen werden, dass die Oberflaeche eines jeden Halte- und Aufnahmemittels im wesentlichen der Form-sowie den Abmessungen der entsprechenden Oeffnungen 6 entspricht. In der Fig. 4 ist ferner die Kolbenzylindereinheit 12,13 dargestellt, die im wesentlichen aus dem Zylinder 13 sowie dem verschiebbaren Kolben und der dazugehoerigen Kolbenstange 12 besteht. Sowohl der Zylinder 13 als auch die Kolbenstange 12 sind gelenkig mit den Halte- und Aufnahmemitteln 9 unter Verwendung von Laschen und Buegeln, die mit 10 und 11 gekennzeichnet sind, verbunden. Ferner kann der Fig. 4 entnommen werden, dass der Zylinder 13 ueber Druckleitungen 14 mit dem Druckmittel beaufschlagt wird.Pivots 9a protrude from the ends of the holding and receiving means 9, which are received by suitable bearings 8, which are fixedly arranged on the surface of the carriage 1, with particular advantage. 4, the skids 17 for creating the cross-country ski trail are in their working position. 4 that the surface of each holding and receiving means corresponds essentially to the shape and the dimensions of the corresponding openings 6. 4 also shows the piston-cylinder unit 12, 13 which essentially consists of the cylinder 13 and the displaceable piston and the associated piston rod 12. Both the cylinder 13 and the piston rod 12 are articulated with the holding and receiving means 9 using tabs and brackets, marked with 10 and 11 connected. 4 that the cylinder 13 is acted upon by the pressure medium via pressure lines 14.

In den Fig. 5 und 6 ist eine weitere vorteilhafte Ausfuehrungsform des erfindungsgemaessen Geraetes zur Erstellung von Loipenpisten dargestellt. Diese abgeaenderte Ausfuehrungsform besteht ebenfalls aus einem flachen Schlitten, der ebenfalls mit Oeffnungen 6 versehen ist, durch die die Kufen 17 zur Erstellung der Langlaufloipe austreten koennen. Die Kufen 17 sind im wesentlichen von einem Zylinder 30 getragen, an dessen Enden die Kufen 17 angeordnet sind. Der Zylinder 30 nimmt in seinem Inneren zwei Kolben auf, die unabhaengig voneinander steuerbar sind, und deren Stangen 31 und 32 an den Enden des Zylinders 30 aus diesem austreten.5 and 6 show a further advantageous embodiment of the device according to the invention for creating cross-country ski runs. This modified embodiment also consists of a flat slide, which is also provided with openings 6 through which the runners 17 can emerge to create the cross-country ski run. The runners 17 are essentially supported by a cylinder 30, at the ends of which the runners 17 are arranged. The cylinder 30 receives two pistons in its interior, which can be controlled independently of one another, and whose rods 31 and 32 emerge from the cylinder 30 at the ends thereof.

Die Stangen 31 bzw. 32 sind ueber Gelenke 33 bzw. 34 und ueber Hebel 35 bzw. 36, deren freie Enden 37 bzw. 38 als Gelenke ausgebildet sind, mit der Oberflaeche 5 des Schlittens 1 wirkverbunden. In vorteilhafter Weise sind zwischen der Oberseite der Kufen 17 und der Schlittenflaeche 5 Faltenbaelge 39 oder aehnliche Schutz- und Abdeckmittel vorgesehen, um zu vermeiden, dass durch die Oeffnungen 6 Schnee dringen koennte und sich auf der Ebene 5 des Schlittens 1 ablegen koennte. Wenn die Stangen 31 und 32 maximal in den Zylinder 30 zurueckgezogen werden, so werden die entsprechenden Kufen 17 zur Erstellung der Langlaufpiste durch die Oeffnungen 6 der Ebene 5 des Schlittens 1 gedrueckt, um sich, wie in der Fig. 5 dargestellt, in ihre Arbeitsposition zu bewegen.The rods 31 and 32 are operatively connected to the surface 5 of the carriage 1 via joints 33 and 34 and via levers 35 and 36, the free ends 37 and 38 of which are formed as joints. 5 bellows 39 or similar protective and covering means are advantageously provided between the top of the runners 17 and the slide surface 5 in order to prevent snow 6 from penetrating through the openings and being able to settle on level 5 of the slide 1. If the rods 31 and 32 are withdrawn as far as possible into the cylinder 30, the corresponding runners 17 for creating the cross-country ski run are opened through the openings 6 Level 5 of the slide 1 is pressed in order to move into its working position, as shown in FIG. 5.

Werden hingegen die Stangen 31 und 32 fuer einen bestimmten Betrag aus dem Zylinder 30 ausgefahren, so werden der Zylinder und somit auch die Kufen 1-7, die mit dem Zylinder 30 verbunden sind, angehoben und in diesem Falle wird die Gleitflaeche der Kufen 17 in Richtung der Schlittenplatte 5 des Schlittens 1 zurueckgezogen. Diese Ausfuehrungsform ist vorteilhaft, da ihr gesamter Aufbau noch einfacher als der der in den Fig. 1 - 4 dargestellten Ausfuehrungsform ist.If, on the other hand, the rods 31 and 32 are moved out of the cylinder 30 for a certain amount, the cylinder and thus also the runners 1-7, which are connected to the cylinder 30, are raised and in this case the sliding surface of the runners 17 in Pulled back towards the slide plate 5 of the slide 1. This embodiment is advantageous because its overall structure is even simpler than that of the embodiment shown in FIGS. 1-4.

In den Fig. 7 - 9, sind einige praktische Beispiele dargestellt, die Anwendungsmoeglichkeiten der erfindungsgemaessen Vorrichtung zur Erstellung von Langlaufloipen darstellt.7-9, some practical examples are shown, which represent possible uses of the device according to the invention for creating cross-country ski trails.

In der Fig. 7 muessen die Spuren 19 der Langlaufloipe, z.B. eine mit S bezeichnete Strasse oder einen Weg ueberqueren. In diesem Falle, bei Fahrt des Schneefahrzeuges in der mit f gekennzeichneten Richtung, werden vor Erreichen der Strasse S' die Halte- und Aufnahmemittel 9 betaetigt und durch Drehen der Haltemittel 9 um ihre Laengsachse wird erzielt, dass die Strasse S vom Schlitten 1 dann ueberquert wird, wenn sich die Kufen 17 in ihrer geschuetzten Ruhelage befinden. Sofort nach Ueberqueren der Strasse S, wird die Hydraulikvorrichtung erneut betaetigt und, durch eine erneute Drehbewegung um ihre Laengsachse, werden die Kufen 17 zur Erstellung der Langlaufloipe wiederum in ihre Arbeitsstellung gebracht.In FIG. 7, the traces 19 must of Langlaufloi p e, for example to cross a designated S road or a path. In this case, when the snow vehicle is traveling in the direction marked with f, the holding and receiving means 9 are actuated before reaching the street S 'and by rotating the holding means 9 about its longitudinal axis it is achieved that the street S is then crossed by the carriage 1 when the runners 17 are in their protected rest position. Immediately after crossing the street S, the hydraulic device is actuated again and, by a new rotary movement about its longitudinal axis, the skids 17 are again brought into their working position for creating the cross-country ski run.

Es hat sich als besonders vorteilhaft erwiesen, die Langlaufloipe auch bei abschuessigem oder ansteigendem Gelaende oder auch bei Kurvenfahrt zu unterbrechen, wie dies schematisch in Fig. 8 dargestellt ist.It has proven to be particularly advantageous to interrupt the cross-country ski even at abschuessi g em or rising terrain or when cornering, as g schematically in Fi. 8 is shown.

Durch die Unterbrechung der Loipe, Unterbrechnung, die durch die erfindungsgemaesse Vorrichtung automatisch vom Fahrerhaus aus gesteuert werden kann, verzichtet man bewusst auf eine formschluessige Fuehrung der Langlaufskier entlang dieser Loipenstrecken, die sonst, besonders fuer einen weniger erfahrenen Langlaeufer Gefahrenquellen mit sich bringen koennte, Gefahrenquellen, die jedoch nicht derartig betont auftreten, wenn das Schneefeld glatt ist, und nicht durch teilweise vereiste Langlaufloipen gepraegt ist.By interrupting the trail, interrupting it, which can be controlled automatically from the driver's cab by the device according to the invention, there is deliberately no form-fitting guidance of the cross-country skis along these trails, which otherwise, especially for a less experienced cross-country skier, could lead to sources of danger which, however, do not appear so emphasized when the snow field is smooth and is not marked by partially icy cross-country trails.

Eine weitere vorteilhafte Einsatzmoeglichkeit der erfindungsgemaessen Vorrichtung zur Erstellung von Langlaufloipen ist in der Vorbereitung des Startplatzes bei Langlaufwettkaempfen zu sehen. Bekanntlich erfolgt der Start dieser Wettkaempfe sehr oft als Massenstart, wogegen die eigentliche Langlaufloipe nach einem kurzen Anfangsstueck nurmehr in zwei Loipen weiterlaeuft, d.h. mit Langlaufloipen, die nur zwei Langlaeufer, die parallel nebeneinander herlaufen, aufnimmt. In diesem Falle, wie derAnother advantageous Einsatzmoe g friendliness of the inventive device for creating cross-country skiing can be seen in the preparation of the launch site at Langlaufwettkaempfen. As is known, the start of these competitions very often takes place as a mass start, whereas the actual cross-country ski run only continues in two cross-country tracks after a short start, ie with cross-country ski runs that only accommodate two cross-country skiers running parallel to each other. In this case, like that

Fig. 9 zu entnehmen ist, koennen am Startplatz zahlreiche parallele Anfangsloipen erstellt werden, die nach dem Start allmaehlich unterbrochen werden und den Langlaeufer dazu einladen, nurmehr auf einer der beiden zentral angeordneten Loipen, die sich ueber die gesamte Loipe erstrecken, weiterzufahren.Fig. 9 shows that numerous parallel starting trails can be created at the launch site, which are gradually interrupted after the start and invite the cross-country skier to do so, only on one of the two centrally located trails Cross-country trails that extend across the entire trail continue.
