Abstract

The shoe, particularly a sport shoe, is provided with a sole of elastic material having a pressure gas chamber. To keep a predetermined gas pressure constant within the chamber, a compressible pump chamber (2) is arranged within the sole (1) which forms a pump working according to the principle of a ball Pump connected to the outside air and to each of the pressure gas chambers (4-13) by a non-return valve (3, 14).

Description

Schuh, insbesondere Sportschuh Shoe, in particular sports shoe

Die Erfindung betrifft einen Schuh, insbesondere Sportschuh, mit einer mindestens eine unter Gasdruck stehende Kammer aufweisenden, aus elastischem Material bestehenden Laufsohle.The invention relates to a shoe, in particular a sports shoe, with an outsole made of elastic material and having at least one chamber under gas pressure.

Ein Schuh dieser Art, dessen Laufsohle in miteinander kommunizierende und mit Druckluft gefüllte Kammern unterteilt ist, ist aus der DE-GMS 77 23 120 bekannt. Bei dem bekannten Schuh ist die Sohle mit einem Füllventil versehen, über das bei Nachlassen des Gasdrucks in den Kammern Luft oder ein anderes Gas nachgefüllt werden kann. Nachteilig bei dem bekannten Schuh ist, daß sich die Elastizität von dessen Laufsohle entsprechend der Temperatur und dem Entweichen von Luft aus den Kammern ständig ändert und daß der Schuh bei Nachlassen seiner Elastizität, also Absinken des Gasdrucks in den Kammern, jedesmal an eine Druckgasquelle angeschlossen werden muß.A shoe of this type, the outsole of which is divided into communicating and filled with compressed air chambers, is known from DE-GMS 77 23 120. In the known shoe, the sole is provided with a filling valve, via which air or another gas can be refilled when the gas pressure in the chambers decreases. A disadvantage of the known shoe is that the elasticity of its outsole corresponds to the temperature and the escape of air the chambers change constantly and that the shoe must be connected to a compressed gas source each time its elasticity, ie the gas pressure in the chambers decreases.

Aufgabe der Erfindung ist es, einen Schuh der eingangs angegebenen Art zu schaffen, in dessen Xammern sich ständig ein vorherbestimmter gleichbleibender Gasdruck aufrechterhalten läßt.The object of the invention is to provide a shoe of the type specified at the beginning, in the xammer of which a predetermined constant gas pressure can be maintained at all times.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß in der Laufsohle eine kompressible Pumpenkammer angeordnet ist, die zur Bildung einer nach dem Prinzip der Bällchenpumpen arbeitenden Pumpe mit der Umgebungsluft und der unter Gasdruck stehenden Kammer über je ein Rückschlagventil in Verbindung steht. Da die Pumpenkammer während des Laufens bei jedem Schritt einmal unter dem Gewicht des Trägers zusammengedrückt und anschließend wieder entlastet wird, fördert die Pumpe ständig Druckluft, die jeden Druckverlust in den in der Sohle gebildeten Kammern auszugleichen vermag.According to the invention this object is achieved in that a compressible pump chamber is arranged in the outsole, which is connected to the formation of a pump working on the principle of the ball pumps with the ambient air and the chamber under gas pressure via a check valve each. Since the pump chamber is compressed under the weight of the wearer once during each step and then relieved again, the pump continuously delivers compressed air which can compensate for any pressure loss in the chambers formed in the sole.

Zur Begrenzung des Drucks der von der Pumpe geförderten Luft kann die Pumpenkammer mit einem Druckbegrenzungsventil versehen sein. Die Pumpe versorgt sodann die unter Druckluft stehenden Kammern nur dann mit Druckluft, wenn der Druck in den Kammern unter das durch das Druckbegrenzungsventil eingestellte Niveau abgesunken ist.In order to limit the pressure of the air delivered by the pump, the pump chamber can be provided with a pressure relief valve. The pump then only supplies the chambers under compressed air with compressed air when the pressure in the chambers has dropped below the level set by the pressure relief valve.

Die von der Pumpe mit Druckluft beaufschlagte Kammer kann auch mit einem den in dieser herrschenden Druck begrenzenden Druckbegrenzungsventil versehen sein, das nach außen oder in das Fußbett münden kann. Mündet das Druckbegrenzungsventil in das Fußbett, kann gleichzeitig auch eine Belüftung des Fußes erreicht werden. Es können auch mehrere über Rückschlagventile mit der Pumpe in Verbindung stehende Kammern vorgesehen sein. Weiterhin kann auch jede Kammer mit einem Druckbegrenzungsventil versehen sein, so daß sich zusätzlich die Möglichkeit ergibt, die Kammern mit unter unterschiedlichem Druck stehender Luft zu füllen.The chamber acted upon by compressed air from the pump can also be provided with a pressure relief valve which limits the pressure prevailing in it and which can open outwards or into the footbed. If the pressure relief valve opens into the footbed, ventilation of the foot can also be achieved at the same time. A plurality of chambers connected to the pump via non-return valves can also be provided. Furthermore, each chamber can also be provided with a pressure relief valve, so that there is also the possibility of filling the chambers with air under different pressure.

Zweckmäßigerweise ist die Pumpenkammer in dem Absatzbereich der Laufsohle angeordnet.The pump chamber is expediently arranged in the heel area of the outsole.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigtAn embodiment of the invention is explained below with reference to the drawing. In this shows

Fig. 1 eine Seitenansicht des Schuhs mit längsgeschnittener Sohle undFig. 1 is a side view of the shoe with a longitudinally cut sole and

Fig. 2 einen Horizontalschnitt durch die Sohle des Schuhs nach Fig. 1.FIG. 2 shows a horizontal section through the sole of the shoe according to FIG. 1.

Der Absatzbereich der Sohle 1 des Schuhs ist als Pumpenkammer 2 ausgebildet. Die Pumpenkammer 2 steht über ein ein Ansaugen von Luft ermöglichendes Rückschlagventil 3 mit der ümgebungsluft in Verbindung.The heel area of the sole 1 of the shoe is designed as a pump chamber 2. The pump chamber 2 is connected to the ambient air via a check valve 3 which enables air to be sucked in.

Die Sohle 1 ist angrenzend an die Pumpenkammer 2 in unter Luftdruck stehende Kammern 4 bis 13 unterteilt. Diese Kammern stehen über Rückschlagventile 14 ait der Pumpenkammer 2 in Verbindung. Weiterhin sind die Kammern mit Druckbegrenzungsventilen 15 versehen, über die bei Auftreten eines Überdrucks Luft nach außen abgegeben wird.The sole 1 is divided adjacent to the pump chamber 2 into chambers 4 to 13 under air pressure. These chambers are connected to the pump chamber 2 via check valves 14. Furthermore, the chambers are provided with pressure relief valves 15, via which air is released to the outside when an overpressure occurs.

Die die Kammern 5 bis 13 mit Druckluft versorgenden Rückschlagventile 14 sind an eine gemeinsame Versorgungsleitung 15 angeschlossen, die von der Pumpenkammer 2 ausgeht. The check valves 14 which supply the chambers 5 to 13 with compressed air are connected to a common supply line 15 which starts from the pump chamber 2.
