Abstract

For the inflation and deflation of an air cushion, in particular for ski boots, a pump (1) with a valve arrangement is proposed, which comprises two valves (3 and 4). The two valves (3 and 4) are arranged in such a manner that, after operation of the operating member (9) of the inlet valve (3) and after a predetermined travel this valve interacts with the operating member (12) of a second valve (4). The second valve (4) is, like the first valve (3), designed as a check valve. Air from the pump chamber can thus be pumped out of the pump chamber of the pump (1) into an air cushion (8) when the check valve (4) is pressed open at the same time as the valve (3) is kept closed. For drawing more air into the air pump (1), the check valve (4) closes automatically, the valve (3) being opened to draw in the air. Finally, for the emptying of air from the cushion (8) and the supply of the valve (3), the valve (4) is opened so that the air can escape via both valves (Fig. 1). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Ventilanordnung für das Aufblasen und Entleeren eines Luftpolsters, insbesondere für Skischuhe, bei welchen eine Pumpe an der Außenseite der Schale oder des Innenschuhes betätigbar angeordnet ist, mit wenigstens einem als Rückschlagventil ausgebildeten Einlaßventil zum Pumpenraum und wenigstens einem als Rückschlagventil ausgebildeten Auslaßventil aus dem Pumpenraum, wobei der Luftpolster über ein Ventil entleerbar ist.The invention relates to a valve arrangement for inflating and deflating an air cushion, in particular for ski boots, in which a pump can be actuated on the outside of the shell or the inner shoe, with at least one inlet valve designed as a check valve for the pump chamber and at least one designed as a check valve Exhaust valve from the pump room, the air cushion being emptied via a valve.

Bei derartigen Ventilanordnungen war es bisher üblich, ein von außen betätigbares, unmittelbar mit dem Luftpolster verbundenes Ventil vorzusehen, über welches Luft aus dem Luftpolster abgelassen werden konnte. Die Pumpe selbst war mit einem Einlaßventil verbunden und über ein Auslaßventil mit dem Luftpolster verbunden. Es mußte somit in der Regel eine Schlauchleitung vom Luftpolster bis zum Auslaßventil für das Ablassen der Luft und eine gesonderte Schlauchleitung zum Auslaßventil der Pumpe verlegt werden. Darüberhinaus waren die beiden Ventile der Pumpe, das Einlaßventil und das Auslaßventil, zumeist als einfache Klappenventile ausgestaltet, wodurch sich eine relativ geringe Dichtheit der Anordnung ergab. Je nach Außentemperaturen veränderten die Ventile ihre Charakteristik und derartige Klappenventile sind darüberhinaus erschütterungsanfällig, so daß bei harten Schlägen Luft unkontrolliert entweichen kann.With valve arrangements of this type, it has previously been customary to provide a valve which can be actuated from the outside and is connected directly to the air cushion and via which air can be discharged from the air cushion. The pump itself was connected to an inlet valve and connected to the air cushion via an outlet valve. It was therefore usually necessary to lay a hose line from the air cushion to the outlet valve for venting the air and a separate hose line to the outlet valve of the pump. In addition, the two valves of the pump, the inlet valve and the outlet valve, were mostly designed as simple flap valves, which resulted in a relatively low tightness of the arrangement. Depending on the outside temperature, the valves changed their characteristics and such flap valves are also prone to vibration, so that air can escape uncontrollably in the event of hard blows.

Die Erfindung zielt nun darauf ab, die Anordnung der eingangs genannten Art zu vereinfachen und baulich kompakter zu halten und gleichzeitig die Möglichkeit zu schaffen präzise funktionierende Ventile einzusetzen. Zur Lösung dieser Aufgabe besteht die Erfindung im wesentlichen darin, daß mit dem Pumpenraum ein von außen betätigbares Einlaßventil und ein mit dem Betätigungsglied des Einlaßventiles kraftschlüssig in Verbindung setzbares betätigbares Auslaßventil verbunden ist, an welches der Luftpolster angeschlossen ist, daß beide Ventile in einem gemeinsamen Bauteil aufgenommen sind, daß die Ventile als federbelastete Ventile, insbesondere Tellerventile, ausgebildet sind und daß die Ventile in öffnungsrichtung hintereinander unter Freilassen eines Ventilhubes angeordnet sind. Durch eine derartige Anordnung ist es möglich, für das Aufblasen und Entleeren eines Luftpolsters mit nur zwei Ventilen das Auslangen zu finden. Dadurch, daß das von außen betätigbare Einlaßventil kraftschlüssig mit einem Betätigungsglied des Auslaßventiles in Verbindung setzbar ist, läßt sich durch Betätigung lediglich eines Ventiles nach einem vorgegebenen Hub auch das zweite Ventil öffnen, so daß ein Ablassen der Luft aus dem Luftpolster über beide Ventile ermöglicht wird. Ein gesondertes Auslaßventil für den Luftpolster wird dadurch entbehrlich. Dadurch, daß bei dieser Ausbildung anstelle der üblicherweise verwendeten Klappenventile federbelastete Ventile, insbesondere Tellerventile, eingesetzt werden, wie sie beispielsweise als Reifenventile eingesetzt werden, werden in bezug auf die Dichtheit im geschlossenen Zustand und in bezug auf den öffnungsdruck wesentlich präzisere und temperaturunabhängigere Werte als bei den üblicherweise verwendeten Klappenventilen erreicht.The invention now aims to simplify the arrangement of the type mentioned and to keep it structurally more compact while at the same time creating the possibility of using precisely functioning valves. To achieve this object, the invention essentially consists in the fact that with the pump chamber an externally operable inlet valve and with the actuator of the inlet valve in a non-positive manner Connection operable outlet valve is connected, to which the air cushion is connected, that both valves are accommodated in a common component, that the valves are designed as spring-loaded valves, in particular poppet valves, and that the valves are arranged one behind the other in the opening direction, leaving a valve stroke free. Such an arrangement makes it possible to find sufficiency for inflating and deflating an air cushion with only two valves. Characterized in that the externally operable inlet valve can be positively connected to an actuator of the outlet valve, the second valve can also be opened by actuating only one valve after a predetermined stroke, so that air can be released from the air cushion via both valves . A separate outlet valve for the air cushion is therefore unnecessary. The fact that spring-loaded valves, in particular poppet valves, such as are used as tire valves, for example, are used in this configuration instead of the flap valves that are usually used, are much more precise and temperature-independent in relation to the tightness in the closed state and in relation to the opening pressure than in the case of reached the normally used flap valves.

Zur weiteren baulichen Vereinfachung und zum Zwecke der Verringerung der Baumaße ist die Anordnung erfindungsgemäß in vorteilhafter Weise so getroffen, daß die Ventile koaxial zueinander und in Achsrichtung aneinander unter Freilassen eines Ventilhubes angeordnet sind. Alternativ kann die Anordnung so getroffen sein, daß die Achsen der beiden Ventile einander etwa unter einem rechten Winkel schneiden, wobei die Bewegungsübertragung vom Einlaßventil auf das Auslaßventil zum willkürlichen Entleeren des Luftpolsters über schiefe Ebenen an den Ventilstangen bewerkstelligt wird. Auf diese Weise kann beim Saughub der Pumpe das Einlaßventil der Pumpe öffnen, ohne daß hiebei das Auslaßventil der Pumpe, über welches die Luft in den Polster strömen soll, betätigt wird. Beim Druckhub der Pumpe wird das Einlaßventil unter der Kraft der Feder an seinen Sitz gepreßt und, da es als Rückschlagventil ausgebildet ist, in dieser Schließlage auch noch durch den Pumpendruck zusätzlich gehalten. Beim Druckhub öffnet nun das Auslaßventil der Pumpe entgegen der Kraft einer Feder und die Luft kann in den Polster gelangen. Nach Beendigung des Druckhubes gelangt das Auslaßventil der Pumpe unter der Kraft der Federn unterstützt durch den im Luftpolster aufgebauten Druck,wiederum in die Schließlage und es kann mittels der Pumpe neuerlich über das Einlaßventil Luft angesaugt werden. Beim Entleeren des Luftpolsters wird das Einlaßventil der Pumpe von außen betätigt und geöffnet. Nach einem vorbestimmten Hub gelangt der Ventilkegel in Kollision mit dem Betätigungsglied des koaxial und in der Achsrichtung nachfolgenden Auslaßventils der Pumpe und es wird auch dieses Ventil geöffnet, so daß nunmehr die Luft aus dem Polster über die beiden geöffneten Ventile entweichen kann. Nach dem Ablassen der gewünschten Menge Luft aus dem Luftpolster werden beide Ventile nacheinander geschlossen und bei einem raschen Schließen beider Ventile herrscht in der Luftpumpe und im Polster etwa gleicher Druck. Es kann somit unmittelbar anschließend, sofern es gewünscht wird, wiederum mit einem Pumphub der Pumpe begonnen werden, ohne daß es erforderlich wäre, durch mehrfaches Niederdrücken einer beispielsweise von einem Ballon gebildeten Pumpe einen entsprechenden Druck aufzubauen, der das als Rückschlagventil ausgebildete Auslaßventil zum Polster wiederum überdrücken kann.For further structural simplification and for the purpose of reducing the dimensions, the arrangement according to the invention is advantageously made such that the valves are arranged coaxially to one another and in the axial direction to one another while leaving a valve stroke free. Alternatively, the arrangement can be such that the axes of the two valves intersect each other at approximately a right angle, the transmission of motion being accomplished from the inlet valve to the outlet valve for the arbitrary emptying of the air cushion over inclined planes on the valve rods. In this way, the inlet valve during the suction stroke of the pump open the pump without operating the pump outlet valve through which the air is to flow into the cushion. During the pressure stroke of the pump, the inlet valve is pressed against its seat under the force of the spring and, since it is designed as a check valve, is additionally held in this closed position by the pump pressure. During the pressure stroke, the outlet valve of the pump opens against the force of a spring and the air can get into the cushion. After the pressure stroke has ended, the outlet valve of the pump reaches the closed position under the force of the springs, supported by the pressure built up in the air cushion, and air can be sucked in again by means of the pump via the inlet valve. When the air cushion is emptied, the inlet valve of the pump is actuated and opened from the outside. After a predetermined stroke, the valve cone comes into collision with the actuating element of the outlet valve of the pump following coaxially and in the axial direction, and this valve is also opened so that the air can now escape from the cushion via the two opened valves. After the desired amount of air has been let out of the air cushion, both valves are closed one after the other and if both valves are closed quickly, the pressure in the air pump and the cushion is approximately the same. It can thus be started immediately afterwards, if desired, with a pump stroke of the pump without it being necessary to build up a corresponding pressure by repeatedly depressing a pump, for example formed by a balloon, which in turn serves as a non-return valve to the cushion can overpress.

Eine baulich kompakte Ausbildung wird dadurch erreicht, daß die beiden Ventile mit einem T-Stück verbunden sind, wobei die beiden Ventile in den T-Balken dieses T-Stückes eingeschraubt, eingeklebt oder eingeschweißt sein können. Bevorzugt ist die Ausbildung des T-Stückes mit einem Innengewinde, da hiebei die handelsüblichen Reifenventile eingesetzt werden können, welche gleichfalls in der Regel verschraubt sind.A structurally compact design is achieved in that the two valves are connected to a T-piece, and the two valves can be screwed, glued or welded into the T-bar of this T-piece. It is preferred to design the T-piece with an internal thread, since this is where the commercially available tire valves come in can be set, which are also usually screwed.

Die Pumpe, welche üblicherweise als Ballonpumpe ausgebildet ist, besteht in der Regel aus elastomerem Kunststoff. Durch Wahl geeigneter Wandstärke des Kunststoffes im Bereich des Anschlußstückes an die Ventile ist es ohne weiteres möglich, das T-Stück einstückig mit der Pumpe auszubilden, so daß es lediglich erforderlich ist, die beiden Ventile in den T-Balken des einstückig mit der Pumpe ausgebildeten T-Stückes einzuschrauben. Die Ventile sind hiebei in einfacher Weise von außen zugänglich und austauschbar.The pump, which is usually designed as a balloon pump, generally consists of elastomeric plastic. By choosing suitable wall thickness of the plastic in the area of the connection piece to the valves, it is easily possible to form the T-piece in one piece with the pump, so that it is only necessary to form the two valves in the T-bar of the piece with the pump Screw the T-piece. The valves are easily accessible and replaceable from the outside.

Um sicherzustellen, daß das von außen betätigbare Einlaßventil der Pumpe nach einem vorbestimmten Hub des Ventiles auch das Auslaßventil der Pumpe in die Offenstellung drücken kann, ist die Ausbildung erfindungsgemäß so getroffen, daß das nach außen ragende Ende der Betätigungsstange des Einlaßventiles der Pumpe in Richtung des Ventilhubes länger bemessen ist als der Ventilhub und bei Betätigung in axialer Richtung entgegen der Kraft einer Feder nach einem vorbestimmten Hub mit der Betätigungsstange des zweiten Ventiles in Anschlag gelangt.To ensure that the externally operable inlet valve of the pump can also press the outlet valve of the pump into the open position after a predetermined stroke of the valve, the design according to the invention is such that the outwardly projecting end of the actuating rod of the inlet valve of the pump in the direction of Valve stroke is longer than the valve stroke and, when actuated in the axial direction against the force of a spring, comes into contact with the actuating rod of the second valve after a predetermined stroke.

Die erfindungsgemäße Ausbildung ermöglicht es in besonders vorteilhafter Weise zwei baugleiche Ventile gleichsinnig hintereinander anzuordnen.The design according to the invention makes it possible in a particularly advantageous manner to arrange two identical valves one behind the other in the same direction.

Eine besonders vorteilhafte und kompakte Ausbildung ergibt sich dann, wenn die Pumpe den die Ventile tragenden Bauteil umgibt und von diesem Bauteil durchsetzt wird, wobei die die Ventile aufnehmende Bohrung dieses Bauteiles über zwischen den beiden Ventilen mündende Durchbrechungen mit dem Pumpenraum verbunden ist.A particularly advantageous and compact design results when the pump surrounds the component carrying the valves and is penetrated by this component, the bore of this component receiving the valves being connected to the pump chamber via openings opening between the two valves.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig. 1 eine erste Ausbildung der erfindungsgemäßen Ventilanordnung mit koaxial angeordneten Ventilen, Fig. 2 eine Ausbildung, bei welcher die Achsen der Ventile einen rechten Winkel miteinander einschließen, und Fig. 3 eine Ausbildung, bei welcher die Pumpe einstückig mit dem Aufnahmeteil für die Ventile ausgebildet ist.The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. In 1 shows a first embodiment of the valve arrangement according to the invention with coaxially arranged valves, FIG. 2 shows an embodiment in which the axes of the valves form a right angle with one another, and FIG. 3 shows an embodiment in which the pump is integral with the receiving part for the valves is formed.

In der Fig. 1 ist mit 1 eine Ballonpumpe bezeichnet, mit welcher einstückig ein T-Stück 2 verbunden ist. In den T-Balken des T-Stückes 2 sind zwei Ventile 3 und 4 eingeschraubt, wobei das Ventil 3 das Einlaßventil und das Ventil 4 das Auslaßventil der Pumpe ist. Das Ventil 3 ist als federbelastetes Tellerventil ausgebildet, wobei die Feder schematisch mit 5 angedeutet ist. Dieses Ventil öffnet nach innen, sobald ein Saugdruck durch die Pumpe 1 ausgeübt wird, und wird durch die Kraft der Feder 5 wiederum in die Schließlage gezogen. Bei einem Saughub gelangt die angesaugte Luft im Sinne des Pfeiles 6 in das Innere der Pumpe 1. Beim nachfolgenden Druckhub durch Zusammenquetschen des Ballons kann die Luft im Sinne des Pfeiles 7 ausgepreßt werden, wobei das zweite Ventil 4, das Auslaßventil der Pumpe, im Sinne des Pfeiles 7 öffnet. Auch dieses Ventil ist wiederum als federbelastetes Tellerventil ausgebildet und ermöglicht nach dem Schließen des Ventiles ein hohes Maß an Druckhaltigkeit im Inneren eines Luftpolsters 8. Zur Entleerung der Luft aus dem Luftpolster 8 wird das Betätigungsglied 9 des Einlaßventiles 3 der Pumpe im Sinne des Pfeiles 10 niedergedrückt, wobei nach einem ersten Ventilhub das Dichtelement 11 des ersten Ventiles 3 mit dem Betätigungsglied 12 des zweiten Ventiles 4 kollidiert. Nach diesem vorbestimmten Hub wird somit auch das zweite Ventil aufgestoßen und die Luft kann im Sinne des Pfeiles 13 aus dem Polster entweichen, wobei gleichzeitig ein Druckausgleich mit dem Innenraum der Pumpe 1 erfolgt. Sobald das Betätigungsglied 9 des ersten Ventiles 3 wiederum freigegeben wird, gelangen beide Ventile 3 und 4 aufgrund der Kraft der Federn in die Schließlage und es kann unmittelbar anschließend mit einem neuerlichen Pumphub begonnen werden, sofern der gewünschte Komfort noch nicht erreicht wurde.In Fig. 1, 1 denotes a balloon pump, with which a T-piece 2 is connected in one piece. Two valves 3 and 4 are screwed into the T-bar of the T-piece 2, the valve 3 being the inlet valve and the valve 4 being the outlet valve of the pump. The valve 3 is designed as a spring-loaded poppet valve, the spring being indicated schematically at 5. This valve opens inwards as soon as a suction pressure is exerted by the pump 1 and is again pulled into the closed position by the force of the spring 5. During a suction stroke, the sucked-in air reaches the inside of the pump 1 in the direction of arrow 6. During the subsequent pressure stroke by squeezing the balloon together, the air can be pressed out in the direction of arrow 7, the second valve 4, the outlet valve of the pump, in the sense arrow 7 opens. This valve, in turn, is designed as a spring-loaded poppet valve and, after the valve has been closed, enables a high degree of pressure retention inside an air cushion 8. To empty the air from the air cushion 8, the actuating element 9 of the inlet valve 3 of the pump is depressed in the direction of arrow 10 , After a first valve stroke, the sealing element 11 of the first valve 3 collides with the actuator 12 of the second valve 4. After this predetermined stroke, the second valve is thus also pushed open and the air can escape from the cushion in the direction of arrow 13, pressure equalization taking place with the interior of the pump 1 at the same time. As soon as the actuator 9 of the first valve 3 is released again, both valves 3 and 4 come into the closed position due to the force of the springs and it can immediately then start again with a new pump stroke if the desired comfort has not yet been achieved.

Bei der Ausbildung nach Fig. 2 sind die beiden Ventile 3 und 4 unter einem Winkel von etwa 90° in einen Aufnahmebauteil 14 aufgenommen. An diesen Bauteil 14 ist wiederum die Ballonpumpe 1 angeschlossen. Die Ventile 3 und 4 sind im wesentlichen baugleich mit den in Fig. 1 dargestellten Ventilen. Am Dichtelement 11 des ersten Ventiles 3 schließt ein eine schräge Steuerfläche 15 aufweisender Koppelteil an, welcher mit dem Betätigungsglied 12 des zweiten Ventiles 4 zusammenwirkt. Ein Niederdrücken des Betätigungsgliedes 9 in Richtung des Pfeiles 10 führt über die schräge Fläche 15 zu einem öffnen des Ventiles 4 in Richtung des Pfeiles 16. Im übrigen entspricht die Funktion des Ventiles der Funktion der Ventile nach Fig. l.In the embodiment according to FIG. 2, the two valves 3 and 4 are accommodated in an accommodating component 14 at an angle of approximately 90 °. The balloon pump 1 is in turn connected to this component 14. The valves 3 and 4 are essentially identical in construction to the valves shown in FIG. 1. Connected to the sealing element 11 of the first valve 3 is a coupling part which has an oblique control surface 15 and which cooperates with the actuating element 12 of the second valve 4. Depressing the actuating member 9 in the direction of arrow 10 leads via the inclined surface 15 to open the valve 4 in the direction of arrow 16. Otherwise, the function of the valve corresponds to the function of the valves according to FIG.

Bei der Ausbildung nach Fig. 3 ist die Ballonpumpe 1 einstückig mit dem die Ventile 3 und 4 aufnehmenden Bauteil 14 ausgebildet. Ebenso wie bei der Ausbildung nach Fig. 2 und im Unterschied zur Ausbildung nach Fig. 1 können die Ventile über Hinterschnitte, wie sie auch bei Schlauchtüllen Verwendung finden, mit dem gummiartigen Werkstoff des die Ventile aufnehmenden Bauteiles 14 verbunden sein. Zur Erleichterung der Ausformbarkeit wird bei dieser Ausbildung die Pumpe einseitig offen hergestellt.
