Gegenstand der Erfindung ist eine Vorrichtung zum Kuppeln von Gasschläuchen mit der Gasleitung einerseits und dem Brenner anderseits unter gleichzeitiger Sperrung bzw. Freigabe des Abschlußhahnes.The invention relates to a device for coupling gas hoses to the gas line on the one hand and the burner on the other hand with simultaneous blocking or release of the Final tap.

Derartige Kupplungsvorrichtungen sind bereits bekannt. Man hat auch diese Kupplungsvorrichtungen so eingerichtet, daß eine den Absperrhahn in der Endstc llung sichernde Sperrvorrichtung nur mittels eines an dem Anschlußstück befindlichen Schlüssels in die Offenstellungen übergeführt werden kann. Bei dieser Vorrichtung ist aber eine besondere Ausbildung der Abschlußvorrichtung im Innern des An-Schlußstückes und des Stutzens erforderlich.Such coupling devices are already known. You also have these coupling devices set up so that a locking device securing the stopcock in the end position only by means of a key located on the connector in the open position can be transferred. In this device, however, is a special training the locking device inside the connection piece and the socket required.

Die vorliegende Erfindung geht von dem Gedanken am, eine Änderung der üblichen Schlauchstücke an den Brennern nicht vorzunehmen. Die Schlauchstücke der Brenner behalten ihre bisherige Form und erhalten lediglich eine aufgesetzte Scheibe, die die Weiterbenutzung des Brenners mit den alten Gummi schläuchen nicht verhindert.The present invention is based on the idea of changing the usual Do not make hose pieces on the burners. Keep the hose pieces from the burners their previous form and only receive a patch that allows continued use of the burner with the old rubber hoses is not prevented.

Der Anschlußhahn der Leitung dagegen ist mit einer Sperrvorrichtung versehen, die nur durch einen zweckmäßig als Schutzglocke ausgebildeten Schlüssel betätigt werden kann. Eine solche Schlüsselschutzglocke ist an beiden Enden des Metallschlauches angebracht. Die Schlüsselschutzglocken greifen einerseits hinter die obenerwähnte Scheibe des Brennerschlauchstückes, anderseits hinter eine am Schlauchstück des Auslaßhahnes sitzende Scheibe. Hier betäligt der Schlüssel eine drehbare zweite Scheibe mit einem Sperrstift, der zwangläufig das Hahnküken derart beeinflußt, daß nur bei ordnungsgemäß aufgesetztem Schlauch ein Öffnen bzw. Gasentnahme stattfinden kann. Gegen willkürliche oder zufällige Öffnung des Hahnes schützt ein ringförmiges Gehäuse mit einer Aussparung für den Sperrstift. Um ohne Gummidichtung einen hinreichend undurchlässigen Abschluß zu erzielen, sind die Kupplungsteile aus verschieden hartem Material hergestellt, während der als Schutzglocke ausgebildete Schlüssel mittels eines Ringes verstellbar ist.The connection tap of the line, however, is provided with a locking device that only can be operated by a key appropriately designed as a protective bell. Such a key protection bell is attached to both ends of the metal hose. the Key protection bells grip on the one hand behind the above-mentioned disc of the burner hose section, on the other hand, behind a disk seated on the hose section of the outlet tap. Involved here the key is a rotatable second disc with a locking pin that inevitably drives the cock plug influenced in such a way that opening or closing can only occur when the hose is properly attached. Gas sampling can take place. Against arbitrary or accidental opening of the tap protects an annular housing with a recess for the locking pin. To without rubber seal To achieve a sufficiently impermeable seal, the coupling parts are made of different hard materials, while the key, which is designed as a protective bell, is adjustable by means of a ring.

Claims

the coupling device are in the connecting pieces of the metal hose. They essentially consist of the protective bell c, which on the one hand protects the connecting piece from injuries, but on the other hand by means of two claws d, which are inserted through recesses a. take hold of a disk b, which connects to the socket piece of the burner or tap. The bell c is mounted on a sleeve m fastened to the coupling piece e by means of a screw g so that it can be moved longitudinally and rotated easily, so that the hose is prevented from twisting when it is connected. A stop I allows the bell to turn only to one side. The slightly conical shape of the disk b causes the connecting piece e to be tightened firmly. In order to secure the tap so that it can only be opened completely or partially when the hose is properly connected, a rotatable disk h is arranged behind the fixed disk b, which is also provided with recesses aa (thus has the shape shown in FIG ). In this case, the connecting pin / falls off the disk b so that the two disks sit close to one another. In contrast, a locking pin i sits firmly on the disk h, in such a way that it holds the cock plug in the closed position as soon as the four recesses α are positioned one behind the other. In this position, the claws d-d of the protective bell can be inserted or removed. Only when the hose has been brought into the position shown in FIG. 6 by rotating the protective bell can the cock plug be opened completely or partially in the usual way. In order to prevent the disk h from being influenced in any other way than by the protective bell c, a protective cap k is attached which completely surrounds the two disks b and h. A recess is provided for the locking pin i through which it passes. The mode of operation of the device is as follows: The metal hose, each provided with a protective bell c at both ends, is first attached to the disk b of a burner, furnace or other gas consumer with one bell. Then the second bell is passed through the recesses α over the disk h of the outlet tap. By turning the bell, the gas hose is connected firmly and tightly to the tap, at the same time the locking pin is placed around and the chick is released for any use. As before, the burner can be set large or small with the outlet tap. The new coupling has the following advantages over the hose connections previously used: Any use of rubber for sealing at any point, but especially at the endangered points (segment of the burner's eye), is eliminated. The regulating capability of the outlet cock remains fully intact. Any opening of the tap, whether intentional or unintentional, is impossible as long as a hose is not connected. The hose can, intentionally or unintentionally, only be pulled off after the tap has been secured in the closed position. The external 'shape of the connecting pieces on the burners etc. remains unchanged. The burners can therefore continue to be used with any hoses. The movable arrangement of the protective bell, which acts as a coupling, prevents the hose from twisting (springs). Godfather NT-Aisf sayings:
