Description

Vorliegende Erfindung hat sich zum Ziel gesetzt, eine für Gasküchen brauchbare, schnell zu bedienende Gasrohrkupplung nach Art eines Bajonettverschlusses zu schaffen. Es sind Gasrohrkupplungen mit Bajonettverschlüssen bekannt, bei welchen die Dichtungsflächen, durch Schraubenfedern aufeinandergepreßt werden. Durch das zum Anschließen der Gasrohrkupplung erforderliche Zusammenpressen der Schraubenfeder: tritt auf die Dauer eine Ermüdung des Federmaterials ein, wodurch eine einwandfreie Abdichtung der Kupplung in Frage gestellt ist.The present invention has set itself the goal of creating a quick-to-use gas pipe coupling in the manner of a bayonet lock which can be used for gas kitchens. There are known gas pipe couplings with bayonet locks in which the sealing surfaces are pressed against one another by helical springs. Due to the compression of the helical spring required to connect the gas pipe coupling: fatigue of the spring material occurs in the long run, which jeopardizes the proper sealing of the coupling.

Bei der vorliegenden Erfindung sind diese Mangel behoben. Der an der Gaszuführungsleitung angeschlossene Kupplungsteil ist mit einem Flansch versehen, auf dessen Schultern wellenförmige, schräg ansteigende Blattfedern eingelassen sind, worauf die sich am Schlauchanschlußstück befindenden Nasen gleiten. Durch Drehen des Schlauchanschlußstückes nach rechts werden die Dichtungsflächen der Kupplung aufeinandergepreßt. Die wellenförmige Ausbildung der Blattfedern verhindert ein selbständiges Zurückgleiten der Kupplungsnasen.The present invention overcomes these shortcomings. The one on the gas supply line connected coupling part is provided with a flange on whose shoulders wave-shaped, obliquely rising leaf springs are embedded, whereupon the hose connector located noses slide. By turning the hose connector to the right the sealing surfaces of the coupling are pressed together. The wavy Formation of the leaf springs prevents the self-sliding back Coupling lugs.

Auf der Zeichnung ist eine beispielsweise Ausführung der Kupplung in perspektivischer Ansicht dargestellt.
Das mit der Gaszuführungsleitung fest verbundene Anschlußstück α besitzt an seinem freien Ende einen Flansch/, auf dessen Schultern sich zwei wellenförmige, nach rechts ansteigende Blattfedern δ befinden, welche an ihren Stützpunktenp, pl im Flansch/ eingelassen sind» Der nach Art einer Überwurfmutter ausgebildete Flansch/1 des Schlauchanschlußstückes ä1 besitzt an seinem Kragen k als Nasen 11, ti1 ausgebildete Gleitstücke.The drawing shows an example of an embodiment of the coupling in a perspective view.
The connection piece α firmly connected to the gas supply line has at its free end a flange /, on whose shoulders there are two undulating leaf springs δ rising to the right, which are embedded in the flange / at their points of support p, p l »The type of a union nut formed flange / 1 of the hose connector 1 has on its collar k as lugs 11, ti 1 formed sliding pieces.

Um die Verbindung mit der Gaszüführungsleitung herzustellen, wird das Schlauchanschlußstück ff1 mit seinen Nasen«,nl durch die Führungsschlitze2,z1 des Flansches/ hindurchgeführt. Durch Drehen nach rechts gleiten die Nasen η,ή1 über die ansteigenden Blattfedern b; dadurch wird die Dichtungseinlage ύί des Flansches/1 gegen die Dich tungsfläched1 des Flansches/ gepreßt, wodurch ein dichter Gasabschluß erfolgt. Die wellenförmige Ausbildung der Blattfedern b verhindert ein Zürückgleiten der Nasen n, ti1. In order to establish the connection with the gas supply line, the hose connector ff 1 with its noses, n 1 is passed through the guide slots 2, z 1 of the flange /. By turning to the right, the lugs η, ή 1 slide over the rising leaf springs b; as a result, the sealing insert ύί of the flange / 1 is pressed against the sealing surface d 1 of the flange /, whereby a tight gas seal takes place. The wave-shaped design of the leaf springs b prevents the lugs n, ti 1 from sliding back.
