Abstract

A sports device ( 10 ), preferably a snow or water vehicle, has an outer shell ( 15 ) which when inflated, forms a support surface ( 13 ) underneath and a lying down or sitting surface ( 20 ) on top. An inflatable tubular shell ( 20 ) with two segments ( 21, 22 ) extending crosswise across it is provided in this outer shell ( 15 ). The outer shell ( 15 ) is formed of a robust fabric which is coated or laminated with plastic. The tubular shell ( 20 ), which is in itself separate from the outer shell, is produced from plastic films, preferably without any fabric reinforcement. The outer shell may also be connected to the tubular shell in such a way that they form a single film. The sports device can therefore be produced with optimal materials for the outer shell or the tubular shell, with the result that it has a long service life.

Description

Die Erfindung bezieht sich auf ein Sportgerät, vorzugsweise ein Schneeoder Wasserfahrzeug, das mit einem Medium, insbesondere Luft, aufblasbar ist, wobei es eine Aussenhülle aufweist, welche in aufgeblasenem Zustand unten eine Auflagefläche und oben eine Liege- bzw. Sitzfläche bildet.The invention relates to a sports device, preferably a snow or Watercraft that is inflatable with a medium, especially air is, wherein it has an outer shell, which in inflated Condition below is a support surface and above is a lying or seating surface forms.

Bei einem gattungsmässigen Sportgerät nach der Druckschrift DE-A-34 34 384, bei dem es sich um einen Luftkissen-Schlitten handelt, sind vier nebeneinander angeordnete Längswülste vorgesehen, die mit Luft aufblasbar sind. Die beiden aussenseitigen Wülste sind rückseitig parallel zueinander und frontseitig konisch nach innen zu einem Spitz verlaufend angeordnet, indessen die beiden inneren Wülste sich in Längsrichtung des Schlittens erstrecken und hierbei als Sitzbereich des Schlittens dienen. Die äusseren Wülste sind unten jeweils mit Führungskufen ausgestattet, welche vorne zu dem Spitz zusammenlaufen. Ferner sind auf der Oberseite der äusseren Wülste Handgriffe angebracht, an denen sich der Benutzer während dem Fahren festhalten kann.In a generic sports device according to the document DE-A-34 34 384, which is an air cushion sled, is four juxtaposed longitudinal beads provided that are inflatable with air are. The two outside beads are parallel on the back towards each other and tapering towards the inside to a point arranged, however, the two inner beads in the longitudinal direction extend the slide and serve here as the seating area of the slide. The outer beads are each equipped with guide runners at the bottom, which converge to the front at the point. Furthermore, on the Top of the outer beads handles attached to which the user can hold on while driving.

Problematisch bei diesem Schlitten ist zum einen dessen Herstellung, bei der dafür zu sorgen ist, dass die Wülste aus einem ausreichend steifen Material gefertigt sind. Denn wenn der Schlitten über einen Gegenstand, wie zum Beispiel einen vorstehenden spitzigen Stein, fahren würde, könnte in der betroffenen Hülle schnell ein Loch entstehen und der erzeugte Luftdruck sofort abfallen. Damit wäre der Schlitten nur noch schlecht oder gar nicht mehr fahrbar. Ausserdem ist nachteilig, dass der Benutzer beim Fahren zur Erzeugung einer Kurve sein Gewicht auf die Aussenseite des Schlittens verlagern muss. Wegen der auf den Fahrer wirkenden Fliehkraft beim Kurvenfahren besteht daher die Gefahr, dass er schnell seitlich vom Schlitten fällt.One problem with this sled is its manufacture, which is to ensure that the beads from a sufficient rigid material are made. Because if the sled is over an object, such as a protruding pointed stone a hole could quickly arise in the affected shell and the air pressure generated drops immediately. That would only be the sled poorly or no longer drivable. It is also disadvantageous that the Users when driving to generate a curve put their weight on the Must shift outside of the carriage. Because of that on the driver acting centrifugal force when cornering there is therefore a risk that he quickly falls off the side of the sled.

Der vorliegenden Erfindung wurde demgegenüber die Aufgabe zugrundegelegt, ein Sportgerät nach der eingangs erwähnten Gattung zu schaffen, welches über eine erhöhte Sicherheit und entsprechend widerstandsfähig mit dem Ziel einer langen Lebensdauer gebaut ist. Ferner soll dieses Sportgerät über eine verbesserte Lenkbarkeit verfügenThe present invention was based on the object a sports device according to the type mentioned at the beginning create which has increased security and accordingly resistant is built with the goal of long life. Further this sports device should have improved maneuverability

Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass innerhalb der Aussenhülle eine aufblasbare Schlauchhülle integriert ist, die entweder zumindest teilweise separat oder mit der Aussenhülle verbunden ist, und wenigstens ein darin sich quer durch erstreckender Verbindungssteg vorgesehen ist, welcher die untere Auflagefläche mit der oben liegenden Liege- bzw. Sitzfläche verbindet The object is achieved in that within the Outer shell is an inflatable inner tube that is integrated either is at least partially connected separately or to the outer shell, and at least one connecting web extending transversely through it It is provided, which is the lower contact surface with the one above Lying or seating area connects

Mit diesem erfindungsgemässen Sportgerät ist durch die Vorsehung der Aussenhülle und der darin enthaltenen Schlauchhülle der wesentliche Vorteil geschaffen worden, dass die Aussenhülle mit einem Material versehen werden kann, welches sehr resistent gegen einen Kontakt mit festen Gegenständen sowie gegen Reibungsabnützung ist, und es darüberhinaus als fertigungstechnischer Vorteil problemlos mit Zusatzteilen, wie Kufen, Handgriffe, Ösen oder weiterem konfektioniert werden kann.With this sports device according to the invention, the The outer shell and the tubular shell contained therein the essential Advantage has been created that the outer shell is provided with a material which can be very resistant to contact with solid Objects as well as against frictional wear, and beyond as a manufacturing advantage with additional parts, such as runners, handles, eyelets or more can be assembled.

Demgegenüber kann die innere Schlauchhülle, die mit Vorteil zusammen mit der Aussenhülle eine einzige Folie bildet, mit einem für ihren Zweck spezifischen Material ausgerüstet werden. Damit kann dieses Gerät auch mit Kufen bestückt werden, so dass es sehr einfach und gut gelenkt werden kann.In contrast, the inner tubular casing, which can be combined with advantage forms a single film with the outer shell, with one for its purpose specific material. So this device can also can be fitted with runners so that it is very easy and well steered can.

In einer sehr vorteilhaften Ausführung sind die jeweils aus je einer oberen und einer unteren Lage Folien gefertigten Aussenhülle und Schlauchhülle an dem Seitenumfang mittels einer durchgehenden Naht rundum miteinander verschweisst, wobei die Aussenhülle aus einem strapazierfähigen Gewebe besteht, welches mit Kunststoff beschichtet oder laminiert ist, indessen die Schlauchhülle aus einer Kunststoffolie besteht. Damit sind optimale Voraussetzungen für ein sicheres und mit hoher Lebensdauer versehenes Sportgerät erreicht worden.In a very advantageous embodiment, they each consist of an upper one and a lower layer of films made outer shell and Hose cover on the side circumference by means of a continuous seam welded all around, the outer shell made of one hard-wearing fabric, which is coated with plastic or is laminated, however, the tubular casing made of a plastic film consists.

Fig.1 zeigt ein Sportgerät 10, welches in der vorliegenden Ausführung insbesondere als Schlitten ausgebildet ist, im Grunde genommen aber als beliebiges Schnee- oder Wasserfahrzeug benutzt werden könnte. Dieses Sportgerät 10 ist mit einem Medium, insbesondere Luft, aufgeblasen und es weist eine Aussenhülle 15 auf, welche in dem aufgeblasenen Zustand unten eine Auflagefläche 13 und oben eine Liege- bzw. Sitzfläche 12 bildet.1 shows a sports device 10, which in the present embodiment is designed in particular as a sled, but basically could be used as any snow or water vehicle. This sports device 10 is inflated with a medium, in particular air and it has an outer shell 15 which is in the inflated State below a support surface 13 and above a lying or Seat 12 forms.

Gemäss Fig.2 sind erfindungsgemäss in der Aussenhülle 15 eine aufblasbare Schlauchhülle 20 und zwei darin sich quer durch erstreckende Verbindungsstege 21, 22 vorgesehen, welche die untere Auflagefläche 13 mit der Liege- bzw. Sitzfläche 12 der Aussenhülle 15 zwecks Abstandsbegrenzung und Formgebung der Aussenhülle verbinden.According to FIG. 2, an inflatable is in the outer shell 15 according to the invention Tubular casing 20 and two extending across it Connecting webs 21, 22 are provided which cover the lower contact surface 13 with the lying or seat surface 12 of the outer shell 15 for the purpose of limiting the distance and shape the outer shell.

Die Aussenhülle 15 und die Schlauchhülle 20 sind jeweils aus zwei entsprechend dimensionierten Folienpaaren 15', 20'; 15", 20" vorgefertigt, welche zum einen die Oberseite und zum anderen die Unterseite des Gerätes 10 bilden. Die zweiteilige Schlauchhülle 20 ist mit ihren Folienlagen 20', 20" annähernd gleich bemessen, wie die ihr zugehörigen Folieniagen 15', 15" der Aussenhülle 15. Diese übereinander gelegten Folienpaare 15', 20'; 15", 20" sind am Seitenumfang mittels einer rundum gehenden Naht 16 miteinander verschweisst, so dass in der Schlauchhülle 20 eine abgeschlossene Kammer entsteht.The outer casing 15 and the tubular casing 20 are each made up of two dimensioned film pairs 15 ', 20'; 15 ", 20" prefabricated, which on the one hand the top and on the other the bottom of the Form device 10. The two-part tubular sleeve 20 is with its film layers 20 ', 20 "dimensioned approximately the same as the associated foil layers 15 ', 15 "of the outer shell 15. These pairs of foils placed one on top of the other 15 ', 20'; 15 ", 20" are on the side circumference by means of an all around welded seam 16 welded together, so that in the tubular casing 20 a closed chamber is created.

Die Aussenhülle 15 ist aus einem strapazierfähigen Gewebe, welches mit einem geeigneten Kunststoff beschichtet oder laminiert ist, und die von dieser an sich separierte Schlauchhülle 20 aus mindestens einer Kunststoff-Folie gefertigt. Die obere Folie 15' der Aussenhülle 15 weist aussenseitig eine rauhe Oberfläche auf, damit eine darauf sitzende Person nicht rutscht. Die Innenseite dieser Folie 15' ist mit Kunststoff beschichtet oder laminiert, damit sie mit der an sich separierten Schlauchhülle 20 sowie mit der unteren Folie verschweisst werden kann.The outer shell 15 is made of a durable fabric, which is coated or laminated with a suitable plastic, and the from this hose sleeve 20, which is separated per se, from at least one Made of plastic film. The upper film 15 'of the outer shell 15 has on the outside a rough surface so that a person sitting on it does not slip. The inside of this film 15 'is coated with plastic or laminated so that they can be separated with the tubular casing 20 and can be welded to the lower film.

Die untere Folie 15" ist ebenfalls aus einem strapazierfähigen Gewebe gefertigt, welches beidseitig mit Kunststoff beschichtet oder laminiert ist. Die Innenseite der unteren Folie ist vorzugsweise mit dem gleichen Kunststoff wie die Innenseite der oberen Folie 15' beschichtet oder laminiert. Die untere Seite der unteren Folie 15" ist mit einem sehr gleitfähigen Kunststoff beschichtet oder laminiert, damit das Sportgerät auf Schnee oder Wasser gut gleitet.The lower film 15 "is also made of a durable fabric made, which is coated on both sides with plastic or laminated. The inside of the bottom film is preferably the same Plastic like the inside of the upper film 15 'coated or laminated. The lower side of the lower film 15 "is very slippery Plastic coated or laminated so that the sports equipment on Snow or water glides well.

Bei einer sehr vorteilhaften Ausführung besteht die obere Folie 15' der Aussenhülle 15 aus einem Polyurethan TPU beschichteten Gorduraund/oder aus einem Nylon-Gewebe, indessen die untere Folie 15", 55" aus einem strapazierfähigen Keflar-, Teflon- oder Nylon-Gewebe gefertigt ist, wobei die Innenseiten beider Folien mit Polyurethan TPU beschichtet oder laminiert sind. Diese die Sitzfläche bildende Aussenseite der oberen Folie ist unbeschichtet, währenddessen diese die Gleitfläche bildende Aussenseite der unteren Folie 15", 55" mit einem mit guten Gleiteigenschaften versehenen PVC- oder TPU-Kunststoff beschichtet oder laminiert ist. Die Schlauchhülle 20 ihrerseits ist aus Polyurethan TPU vorzugsweise ohne Gewebezusatz gefertigt. Mit dieser Kombination von Werkstoffen ergibt sich insbesondere der Vorteil, dass diese beiden unterschiedlichen Hüllen sehr gut miteinander verschweisst werden können. Selbstverständlich liessen sich grundsätzlich auch andere Materialien verwenden, welche den erforderlichen Eigenschaften für dieses Sportgerät 10 gerecht werden.In a very advantageous embodiment, there is the upper film 15 ' Outer shell 15 made of a polyurethane TPU coated Gordura and / or made of a nylon fabric, the lower film 15 ", 55" made from a hard-wearing Keflar, Teflon or nylon fabric is, the inside of both foils coated with polyurethane TPU or are laminated. This outside that forms the seat the top film is uncoated, meanwhile this is the sliding surface forming outside of the lower film 15 ", 55" with a good PVC or TPU plastic coated with sliding properties or is laminated. The tubular casing 20 in turn is made of polyurethane TPU preferably made without added fabric. With this combination The particular advantage of materials is that these two different casings can be welded together very well. Of course, other materials can of course also be used use what the required properties for this Sports device 10 meet.

Im Rahmen der Erfindung sind zwei annähernd symmetrisch zur LängsMittelachse der Aussenhülle 15 verlaufende Verbindungsstege 21. 22 vorgesehen. Diese ebenfalls aus einem der Gewebebeschichtung entsprechenden Kunststoff hergestellten Verbindungsstege 21, 22 sind jeweils unten bei der Auflagefläche 13 und oben bei der Sitzfläche 12 zusammen mit der Aussenhülle 15 und der Schlauchhülle 20 je zu einer Längsnaht 17, 18 verschweisst, durch welche in der Mitte ein Längswulst und aussen je ein solcher erzeugt ist. Eine durchgehende Längsnaht 17, 18 ergibt gemäss Fig.1 einen gleichmässigen geradlinigen Spalt zwischen den Wülsten.In the context of the invention, two are approximately symmetrical to the longitudinal central axis the outer sheath 15 connecting webs 21, 22nd intended. This also from a corresponding to the fabric coating Plastic-made connecting webs 21, 22 are each below at the contact surface 13 and above at the seat surface 12 together with the outer shell 15 and the tubular shell 20 to one each Longitudinal seam 17, 18 welded, through which a longitudinal bead in the middle and one is generated on the outside. A continuous longitudinal seam 17, 18 results in a uniform rectilinear gap between the beads.

Diese Verbindungsstege 21, 22 sind annähernd über die gesamte Länge der Aussenhülle 15 ausgebildet. Es ist jedoch vorne und hinten eine Verbindung zwischen den einzelnen Kammern 26 vorhanden, damit nur ein Ventil 14 für das Einfüllen bzw. Auslassen der Luft notwendig ist. Dies bietet ausserdem den Vorteil, dass die Luft bei einer Gewichtsverlagerung des Fahrers gleichmässig in die entlasteten Kammern ausweichen kann. Im Prinzip könnten aber auch die drei Kammern 26 voneinander getrennt und jeder ein separates Ventil 14 zugeordnet sein.These connecting webs 21, 22 are approximately over the entire length the outer shell 15 is formed. However, it is one in the front and one in the back Connection between the individual chambers 26 available, so only a valve 14 is necessary for filling or discharging the air. This also has the advantage that the air in a weight shift dodge the driver evenly into the relieved chambers can. In principle, however, the three chambers 26 could also be separated from one another separated and each be assigned a separate valve 14.

Beim Zusammenschweissen der Folienlagen 15', 15"; 20', 20" und der Verbindungsstege 21, 22 werden vorerst die Verbindungen bei den Längsnähten 17, 18 und erst anschliessend die Naht 16 am Aussenumfang vorteilhaft durch ein an sich bekanntes hochfrequentes Elektroschweissen erzeugt.When welding the film layers 15 ', 15 "; 20', 20" and the Connecting webs 21, 22 are the connections for the time being Longitudinal seams 17, 18 and only then the seam 16 on the outer circumference advantageous by a known high-frequency electrowelding generated.

Die Aussenhülle 15 bildet in aufgeblasenem Zustand, wie in Fig. 1 dargestellt ist. eine Matratzenform und sie ist hierbei seitlich nach vorne verjungt. Ausserdem ist an ihr beidseitig je ein Handgriff 11 befestigt. Hieraus ergibt sich der weitere Vorteil, dass nämlich an dieser Aussenhülle 15 problemlos solche Zusatzteile, wie Handgriffe 11, Ösen, Taschen oder dergleichen angebracht werden können, ohne dass Abdichtprobleme entstehen würden, da die Schlauchhülle von diesen Zusatzteilen getrennt ist Einzig das Ventil 14 erstreckt sich durch die Aussenhülle bis in das Schlauchinnere.The outer shell 15 forms in the inflated state, as shown in Fig. 1 is. a mattress shape and it is tapered laterally towards the front. In addition, a handle 11 is attached to it on both sides. From this there is the further advantage that this outer shell 15 easily such additional parts, such as handles 11, eyelets, bags or the like can be attached without sealing problems would arise, since the tubular casing is separated from these additional parts is only the valve 14 extends through the outer shell into the inside of the hose.

Die Materialien der Aussenhülle 15, der Schlauchhülle 20 sowie der Verbindungsstege 21, 22 sind derart biegsam ausgebildet, dass das Gerät 10 leicht zusammengefaltet und zum Beispiel in einem Rucksack versorgt werden kann.The materials of the outer casing 15, the tubular casing 20 and the Connecting webs 21, 22 are designed to be flexible in such a way that the device 10 easily folded and stored in a backpack, for example can be.

Fig.3 zeigt das Sportgerät 10 von unten, bei welchem in seiner Längsrichtung angeordnete Kufen 31, 32 ersichtlich sind, die an der Auflagefläche 13 der Aussenhülle 15 befestigt sind. Die beiden aussenseitigen Kufen 32 sind nicht gerade, sondern mit einem Radius R nach aussen abgebogen. Damit kann ein Fahrer sein Gewicht auf eine die Innenseite des Schlittens verlagern und damit mehr Druck auf eine dieser beiden Kufen 32 erzeugen. Durch diese leicht taillierte Ausführung der Kufen 32 erzeugt der Schlitten bei einer Gewichtsverlagerung auf die eine oder andere dieser Kufen quasi selbsttätig eine Kurve. Der Radius R ist vorzugsweise in der Grössenordnung zwischen 5 und 20 Metern bemessen. Figure 3 shows the sports device 10 from below, in which in its longitudinal direction arranged runners 31, 32 can be seen on the bearing surface 13 of the outer shell 15 are attached. The two outside Skids 32 are not straight, but with a radius R to the outside bent. This allows a driver to put his weight on the inside relocate the sled and put more pressure on one of them Generate skids 32. Due to this slightly waisted version of the skids 32 the sled generates a weight shift to one or the other other of these runners almost automatically a curve. The radius R is preferred in the range of 5 to 20 meters.

Gemäss Fig.4 ist als Variante an der Auflagefläche 13 der Aussenhülle 15 eine Profilplatte 35 mit mehreren nebeneinander angeordneten T-Nuten 36 für die Aufnahme von angedeuteten Kufen 37 eingeschweisst. Damit ist verdeutlicht, dass durch die erfindungsgemässe Ausbildung des Gerätes je nach Bedarf verschiedenartige Lösungen ausgeführt werden können.According to Figure 4 is a variant on the bearing surface 13 of the outer shell 15 a profile plate 35 with a plurality of T-grooves arranged side by side 36 welded for receiving indicated runners 37. This makes it clear that the training according to the invention various types of solutions can be implemented as required can.

Zu diesem Zwecke weist obere Folie 55' aussenseitig die rauhe Oberfläche mit dem strapazierfähigen Gewebe 56 auf, auf der Innenseite 57 ist sie mit Kunststoff beschichtet oder laminiert und bildet hierbei die Schlauchhülle. Die untere Folie 55" ist ebenfalls aus dem strapazierfähigen Gewebe 56 gefertigt, zudem - die Schlauchhülle bildend - auf der Innenseite 58 mit Kunststoff beschichtet oder laminiert, und auf der Aussenseite 59 - die Gleitfläche bildend - mit dem entsprechend gleitfähigen Kunststoff versehen.According to Figure 6, the outer shell 55 is made of a durable fabric manufactured, which in turn coated or laminated with plastic is. For this purpose, the upper film 55 'has the rough outside Surface with the hard-wearing fabric 56 on the inside 57 it is coated or laminated with plastic and forms the Tubular casing. The bottom slide 55 "is also made of durable Fabric 56 manufactured, also - forming the tube cover - on the Inside 58 coated or laminated with plastic, and on the outside 59 - forming the sliding surface - with the correspondingly sliding Plastic.

Zudem ist bei diesem Sportgerät 50 vorteilhaft bei all den Stellen, bei denen auf der Aussenhülle 55 Zusatzteile, wie Kufen, Handgriffe 11, Ösen oder die Ventile 14 angebracht sind, jeweils an der Innenseite der Schlauchhülle 60 ein separates Folienstück 52, 53 befestigt, insbesondere angeschweisst, so dass bei diesen Stellen eine zusätzliche Abdichtung erzeugt ist.In addition, this sports device 50 is advantageous in all the places at those on the outer shell 55 additional parts, such as runners, handles 11, Eyelets or the valves 14 are attached, each on the inside of the Hose cover 60 attached a separate piece of film 52, 53, in particular welded on, so that an additional seal at these points is generated.

Dieses Sportgerät wird vorzugsweise als Schlitten verwendet, der sehr einfach lenkbar ist und sich auch für den Tiefschnee eignet.This sports device is preferably used as a sled, which is very is easy to steer and is also suitable for deep snow.

Die Erfindung ist mit den oben erläuterten Ausführungsbeispielen ausreichend dargetan. Sie liesse sich jedoch noch in anderen Varianten darstellen. Im Prinzip könnte die Schlauchhülle auch komplett separat von der Aussenhülle gefertigt und in letzterer eingelegt und darin mit Vorteil befestigt sein.The invention is sufficient with the exemplary embodiments explained above demonstrated. However, it could still be used in other variants represent. In principle, the tubular casing could also be completely separate made of the outer shell and inserted in the latter and in it Advantage to be attached.

In der Schlauchhülle 20 könnte auch nur eine oder aber mehr als zwei solcher sich quer durch erstreckender Verbindungsstege vorgesehen sein.Only one or more than two could be in the tubular casing 20 such provided across connecting webs extending his.

Die Aussenhülle als auch die Schlauchhülle könnten aus jeweils einer strumpfförmigen Hülle bestehen und nur vorne und hinten zusammen verbunden sein. Auch deren Aussenform kann selbstverständlich anders als dargestellt ausgebildet sein, bspw. eher rund, oval, als Ellipse oder dergleichen.The outer casing as well as the tubular casing could each consist of one stocking-shaped sheath and only together at the front and back be connected. Of course, their outer shape can also be different be designed as represented, for example, rather round, oval, than ellipse or like.
