Description

Die Erfindung bezieht sich auf ein Luftkissen für einen Schuh, insbesondere Skischuh, das von einer Luftpumpe aufblasbar ist, wobei das Luftkissen, das als Zungen- oder Fersenpolster ausgebildet ist, und die Luftpumpe aus elastischem Werkstoff bestehen und die Luftpumpe von außen betätigbar angeordnet ist.The invention relates to an air cushion for a shoe, in particular a ski boot, which can be inflated by an air pump, the air cushion, which is designed as a tongue or heel cushion, and the air pump being made of elastic material and the air pump being arranged to be actuatable from the outside.

Es ist bekannt, bei einem Skischuh mit einem vorzugsweise als Schale ausgebildeten Außenschuh, mit einem Innenschuh und mit einem aufblasbaren Luftpolster, letzteres zwischen dem Außenschuh und dem Innenschuh anzuordnen und mit dem Außenschuh fest zu verbinden.It is known to arrange a ski boot with an outer shoe, which is preferably designed as a shell, with an inner shoe and with an inflatable air cushion, the latter between the outer shoe and the inner shoe and to firmly connect it to the outer shoe.

Es ist weiterhin in verschiedenen Ausführungen bekannt, eine aufpump- und ablaßbare Luftblase an der Innenseite eines Skischuhes anzuordnen und dabei eine Luftpumpe am Skistiefel anzubringen. Bei einer solchen Anordnung mit einer steifen Außenschale aus Kunststoff wird der Luftpolster über ein die Schale durchsetzendes Ventil aufgeblasen, und zwar Hilfe einer mit dem Ventil in ständiger Verbindung stehenden, mit dem Schuh fest verbundenen und von außen betätigbaren Luftpumpe ; diese kann auch in einer Durchbrechung der Schale eingesetzt sein und sie kann aus einer Kolbenpumpe mit zur Sohle etwa senkrecht stehender Achse des Zylinders oberhalb des Fersenteiles bestehen.It is also known in various designs to arrange an inflatable and deflatable air bubble on the inside of a ski boot and to attach an air pump to the ski boot. In such an arrangement with a rigid outer shell made of plastic, the air cushion is inflated via a valve passing through the shell, with the aid of an air pump which is in constant connection with the valve, is firmly connected to the shoe and can be actuated from the outside; this can also be inserted in an opening in the shell and it can consist of a piston pump with the axis of the cylinder approximately perpendicular to the sole above the heel part.

Aus der FR-A 2 407 682 ist ein Luftkissen für Skischuhe bekanntgeworden, bei welchem die Luftpumpe über Schlauchverbindungen mit dem Luftpolster verbunden ist, wodurch sich diese Pumpe in einfacher Weise in einer Durchbrechung der Schale anordnen läßt. Aus der US-A 3 664 043 ist eine Ausbildung eines Luftkissens zu entnehmen, bei welchem die Pumpe in einfacher Weise ansetzbar und abnehmbar ausgebildet ist.From FR-A 2 407 682 an air cushion for ski shoes has become known, in which the air pump is connected to the air cushion via hose connections, whereby this pump can be arranged in a simple way in an opening in the shell. From US-A 3 664 043 an embodiment of an air cushion can be seen, in which the pump can be attached and removed in a simple manner.

Nachteilig ist bei diesen bekannten Ausbildungen der hohe bauliche Aufwand für die Luftpumpe und das Luftkissen bzw. deren Verbindungsteile und die umständliche und für den Gebraucher unbequeme Handhabung.A disadvantage of these known designs is the high structural outlay for the air pump and the air cushion or their connecting parts and the complicated and uncomfortable handling for the user.

Die Erfindung stellt sich die Aufgabe, hier Abhilfe zu schaffen und ein Luftkissen bzw. einen Schuh, insbesondere Skischuh, zu schaffen, des besonders einfach aufgebaut, leicht herzustellen und bequem handzuhaben ist.The object of the invention is to remedy this and to create an air cushion or a boot, in particular a ski boot, which is particularly simple in construction, easy to manufacture and easy to handle.

Gemäß der Erfindung ist das Luftkissen für einen Schuh, insbesondere Skischuh, der eingangs genannten Art dadurch gekennzeichnet, daß das Luftkissen und die Luftpumpe aus einem Stück bestehen, wobei die Luftpumpe oben Abschlußwulst des Zungenpolsters an der Au- βenseite des Zungenpolsters oder im oberen Abschlußwulst des Fersenpolsters angeordnet ist.According to the invention, the air cushion for a shoe, in particular a ski boot, of the type mentioned at the outset is characterized in that the air cushion and the air pump consist of one piece, the air pump at the top bead of the tongue pad on the outside of the tongue pad or in the top bead of the Heel pad is arranged.

Auf diese Weise wird mit kleinem baulichen Aufwand ein leicht und bequem handhabbares Luftkissen vorgesehen, das jederzeit nach Wunsch mehr weniger der Luftpumpe beaufschlagbar ist.In this way, an easily and conveniently manageable air cushion is provided with little construction effort, which can be acted upon less by the air pump at any time.

Wenn das Luftkissen für sich als gesonderter Teil des Schuhes ausgebildet ist, läßt es sich bei bekannten Schuhen, ohne Veränderungen an diesen bzw. deren Innen- und Außenschuh, verwenden, auch mit Vorteil für solche, die eine steife Schale, z. B. aus Kunststoff, als Außenschuh und einen weichen Innenschuh aufweisen.If the air cushion is designed as a separate part of the shoe, it can be used in known shoes without changes to these or their inner and outer shoe, also with advantage for those who have a rigid shell, for. B. made of plastic, as an outer shoe and a soft inner shoe.

Weitere Merkmale der Erfindung ergeben sich aus der Beschreibung zweier Ausführungsbeispiele an hand der Zeichnung ; es zeigen :

  • Figur 1 eine teilweise geschnittene Seitenansicht eines Skischuhes mit einem als Zungenpolster ausgebildeten Luftkissen und
  • Figur 2 eine ähnliche Darsellung mit einem als Fersenpolster ausgebildeten Luftkissen.
Further features of the invention result from the description of two exemplary embodiments with reference to the drawing; show it :
  • Figure 1 is a partially sectioned side view of a ski boot with an air cushion designed as a tongue pad and
  • Figure 2 shows a similar presentation with an air cushion designed as a heel cushion.

Bei der Ausbildung nach Figur 1 ist das Luftkissen 1 als Zungenteil eines Skischuhes 2 ausgebildet und wie dargestellt vorzugsweise in diesen integriert, d. h. mit ihm fest verbunden. Das Luftkissen 1 besteht aus einem größeren Teil aus dem eigentlichen, den Luftpolster bildenden Zungenteil 3 und einem an dessen oberen Ende angesetzten, hohlen Wulstteil 4, der eine Luftpumpe bildet. Das Kissen 1 bzw. seine Teile 3, 4 sind aus elastischem Werkstoff, z. B. Gummi, aus einem Stück bestehend hergestellt, wobei die Wandstärke des Wulstteiles 4 größer ist, da er sich, nach dem Zusammendrücken als Luftpumpe, wieder in die Ausgangsform zurückbilden muß.In the embodiment according to FIG. 1, the air cushion 1 is designed as a tongue part of a ski boot 2 and, as shown, is preferably integrated into this, ie. H. firmly connected to him. The air cushion 1 consists of a larger part of the actual tongue part 3 forming the air cushion and a hollow bead part 4 attached to its upper end, which forms an air pump. The pillow 1 and its parts 3, 4 are made of elastic material, for. B. rubber, made of one piece, the wall thickness of the bead part 4 is greater, since it must, after compressing as an air pump, revert to the original shape.

In dieser Weise werden von den Teilen 3, 4 zwei Kammern 5, 6 umschlossen, wobei die Kammer 6 der durch den Wulstteil 4 gebildeten Luftpumpe über ein Rückschlagventil 7 mit der Außenluft und über ein weiteres Rückschlagventil 8 mit der Kammer 5 im Zungenteil 3 in Verbindung steht. In dieser Kammer 5 ist auch ein Ablaßventil 9 vorgesehen, durch dessen Betätigung der Druck aus der Kammer 5 abgelassen werden kann.In this way, the parts 3, 4 enclose two chambers 5, 6, the chamber 6 of the air pump formed by the bead part 4 via a check valve 7 with the outside air and via a further check valve 8 with the chamber 5 in the tongue part 3 in connection stands. In this chamber 5 there is also a drain valve 9, by the actuation of which the pressure can be released from the chamber 5.

Drückt man sohin auf die Kammer 6 im Wulstteil 4, wirkt dieser als Luftpumpe und beaufschlagt über das Ventil 8 die Kammer 5, die als Luftpolster für das Kissen 1 wirkt. Durch Betätigung des Ablaßventiles 9 kann das Luftkissen 1 bzw. dessen Kammer 5 wieder entlüftet werden.If one presses on the chamber 6 in the bead part 4, the latter acts as an air pump and acts on the chamber 5 via the valve 8, which acts as an air cushion for the cushion 1. The air cushion 1 or its chamber 5 can be vented again by actuating the drain valve 9.

Die Ausbildung nach Fig. 2 ist im Prinzip gleichartig aufgebaut, wobei die Bezugszeichen dieselbe Bedeutung wie zu Fig. 1 besitzen, mit dem Unterschied, daß das Luftkissen 1 einen Fersenteil .3 mit einer Kammer 5 und einer Kammer 6 im oberen Abschlußwulst 4 aufweist und hier als Fersenpolster im Schuh 2 vorgesehen ist.The design according to FIG. 2 is constructed in principle in the same way, the reference numerals having the same meaning as in FIG. 1, with the difference that the air cushion 1 has a heel part .3 with a chamber 5 and a chamber 6 in the upper end bead 4 and is provided here as a heel pad in shoe 2.

Wie erwähnt, kann das Luftkissen auch als für sich in den Schuh 2 einsetzbarer Teil ausgebildet sein, der in einen üblichen Schuh, insbesondere Skischuh, einsetzbar ist.As mentioned, the air cushion can also be designed as a part which can be inserted into the shoe 2 and which can be inserted into a conventional shoe, in particular a ski shoe.
