Description

An- und Abstellvorrichtung für Preßluftwerkzeuge. Die Erfindung hat eine An- und Abstellvorrichtung für Preßluftwerkzeuge zum Gegenstande, durch die bewirkt wird, daß das Werkzeug ,sich selbsttätig vom Treibmittel abschaltet, wenn der Arbeitskolben zum Leerschlag kommt und daß das Treibmittel selbsttätige Zuströmung erhält, wenn das Werkzeug gegen das, Werkstück angedrückt wird.Positioning and parking device for compressed air tools. The invention has an on and off device for compressed air tools to the subject, through the causes the tool to switch itself off from the propellant when the working piston comes to a blank stroke and that the propellant flows automatically obtained when the tool is pressed against the workpiece.

Die neue Vorrichtung besteht darin, daß der Hebel den festen Griff des Werkzeuges, in sich aufnimmt; er ist zu diesem Zwecke U-förmig ausgebildet und umgibt den Griff mantelartig.The new device is that the lever is the firm grip of the tool, in takes up; for this purpose it is U-shaped formed and surrounds the handle like a jacket.

In der Zeichnung ist der Gegenstand der Erfindung in zwei Abbildungen. dargestellt. Abb. i zeigt einen Längsschnitt, Abb. a eine Vorderansicht mit Schnitt durch Griff und Hebel.In the drawing, the subject matter of the invention is shown in two figures. shown. Fig. I shows a longitudinal section, Fig. A shows a front view with a section by handle and lever.

Der Griff a eines Gesteinsbohrhammers ist als fester Griff so ausgeführt, daß das Handloch b auch an seiner Oberseite durch den Rücken c. des Griffes geschlossen ist. Über diesen Rücken c legt sich schlüssig der Hebel d, der im Bolzen e an den Griff a angelenkt ist. Der Hebeld ist irn Querschnitt U-förmig gestaltet, so daß er am Rücken c mit seinen beiden Wangen gute Führung findet; er liegt mit seinen schwingenden Enden gegen den Ventilstift/ an, den er niederdrückt, sobald das Werkzeug unter den Arbeitsdruck gebracht wird.The handle a of a rock drill is designed as a fixed handle in such a way that that the hand hole b also on its upper side through the back c. of the handle closed is. The lever d, which is in the bolt e to the Handle a is hinged. The lever is U-shaped in cross-section, so that he finds good guidance on the back c with both of his cheeks; he lies with his swinging ends against the valve pin /, which it depresses as soon as the tool is brought under the working pressure.

Der runde Griff liegt also bequem in der Hand, und er gewährt eine sichere Führung des. Werkzeuges, was namentlich bei Abbauhärrmern und Pickhämmern, die zum Brechen iles angebohrten Werkstückes,dienen, von Bedeutung ist. Der Griff findet guten Halt am Rücken c, und der Rücken e überträgt, da er ein festes Stück des u'erkzeuges ist, jede Bewegung der Hand in einwandfreier Weise. Verletzungen oder Klemmungen sind ausgeschlossen, da sich die Bewegung der beiden Teile gegeneinande: außerhalb des Hebels vollzieht.The round handle lies comfortably in the hand, and it grants one safe guidance of the tool, which is particularly important in the case of demolition hammers and pick hammers, which are used to break iles drilled workpiece, is of importance. The handle finds a good hold on the back c, and the back e transfers because it is a solid piece of the tool is to make every movement of the hand in an impeccable manner. Injuries or jamming are excluded, as the movement of the two parts against each other: takes place outside the lever.
