Description

Die bekannten Verbindungen von Werkzeuggriffen mit dem ein hydraulisches oder pneumatisches Druckmittel zuführenden Schlauch ergeben eine oft unerwünscht große Baulänge und machen das Werkzeug unhandlich; auch bedingen sie meist störende Schlauchschellen und -verbinder.The known connections of tool handles with a hydraulic one or pneumatic pressure medium feeding hose result in an often undesirable large overall length and make the tool unwieldy; they also usually cause disturbances Hose clamps and connectors.

Nach der Erfindung ist der Werkzeuggriff als Muffe mit sägezahnartig profilierter Bohrung ausgebildet, in die der Schlauch unter Spannung eingeführt wird. Dies ergibt die Vereinigung von Schlauchmuffe und Werkzeuggriff und damit eine kurze Baulänge und eine verbesserte Handlichkeit Durch den im Schlauch herrschenden Betriebsdruck wird der Schlauch gedehnt und dadurch gehalten und abgedichtet.According to the invention, the tool handle is as a sleeve with sawtooth-like profiled bore formed into which the hose is inserted under tension will. This results in the union of hose sleeve and tool handle and thus a short overall length and improved handiness by the prevailing in the hose Operating pressure, the hose is stretched and thus held and sealed.

Einen völlig dichten Anschluß des Schlauches kann man dabei mit einfachen Mitteln erreichen, wenn gemäß einer Ausführungsform der Erfindung am inneren Ende der Muffenbohrung ein kegeliger Dorn angebracht wird und die Profilierung der Muffe durch Gewindegänge gebildet wird, so daß der Schlauch in die Muffe eingeschraubt werden kann und gegen Ende des Einschraubens eine zusätzliche Spannung durch den in ihn eindringenden Dorn erhält.A completely tight connection of the hose can be achieved with simple Achieve means when in accordance with an embodiment of the invention at the inner end a conical mandrel is attached to the socket bore and the profile of the socket is formed by threads so that the hose is screwed into the sleeve can be and towards the end of the screwing in an additional tension by the gets into him penetrating thorn.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Längsmittelschnitt dargestellt.The drawing shows an embodiment of the subject matter of the invention shown in longitudinal center section.

Der mit einem Gummiüberzug 4 versehene Werkzeuggriff i hat eine Bohrung 5, die sägezahnartig profiliert ist. Vorzugsweise wird diese Profilierung durch Gewindegänge gebildet, so daß der mit dem Griff i zu verbindende Gummischlauch 2 in die Muffe eingeschraubt werden kann. Am inneren Ende des Werkzeuggriffes ist ein kegeliger Dorn 3 angebracht. Beim Einschrauben des Schlauches 2 in den Griff dringt dieser Dorn in den Schlauch ein. Dadurch erhält der Schlauch eine zusätzliche Spannung.The tool handle i, which is provided with a rubber coating 4, has a bore 5, which is profiled like a sawtooth. This profiling is preferably carried out by Formed threads, so that the rubber hose 2 to be connected to the handle i can be screwed into the socket. At the inner end of the tool handle is a conical mandrel 3 attached. When screwing the hose 2 into the handle this thorn penetrates the hose. This gives the hose an additional one Tension.

Die Erfindung kann Anwendung finden beispielsweise an Spritzpistolen, Blasdüsen, Preßluft-Stampfern, Preßluftbohrmaschinen u. dgl.The invention can be used, for example, on spray guns, Blow nozzles, compressed air rammers, compressed air drills and the like.
