Description

Bei Spritzpistolen, wie sie beispielsweise zum Zerstäuben von Farbe, Lack od. dgl. verwendet werden, fehlt es bisher an einer geeigneten, den Schlauch mit der Spritzpistole verbindenden Kupplung.In the case of spray guns, such as those used for atomizing paint, Varnish or the like are used, there is currently no suitable hose with the spray gun connecting coupling.

Wenn beispielweise mit mehreren Pistolen verschiedenfarbig gespritzt werden soll, muß bei den bisherigen Ausführungen die Druckluftleitung zunächst von Hand abgestellt, das Spritzgerät vom Nippel abgeschraubt und die andere Pistole wieder mit dem Schlauchnippel verschraubt werden. Diese Manipulationen sind unerwünscht, zeitraubend und umständlich, zumal da die Pistole mit dem auf ihr befestigten Farbbehälter wiederholt um sich selbst gedreht werden muß.For example, when sprayed in different colors with several guns is to be, in the previous versions the compressed air line must first be from Hand turned off, unscrewed the sprayer from the nipple and the other gun screwed back to the hose nipple. These manipulations are undesirable, Time-consuming and cumbersome, especially since the gun with the paint container attached to it has to be rotated repeatedly on itself.

Nach der Erfindung befindet sich an der Spritzpistole die eine Kupplungshälfte eines an sich bekannten, sich selbsttätig schließenden Druckluftschlauchverbinders, dessen andere Hälfte über eine Schlauchkupplung mit dem Schlauchnippel kombiniert ist. Abgesehen davon, daß durch die vorhandene Schlauchkupplung das bisherige behelfsmäßige Festklemmen des Schlauches am Nippel vermieden ist, wird durch die Erfindung der Vorteil erzielt, daß; wenn beispielsweise eine Spritzpistole gegen eine andere ausgetauscht werden soll, nur mittels eines einfachen Handgriffs der Schlauch zusammen mit der einen Kupplungshälfte von der einen Pistole losgekuppelt und auf die andere Pistole aufgesteckt zu werden braucht. Dabei wird die Druckluft im entkuppelten Zustand sebsttätig abgestellt, so daß es einer besonderen Betätigung eines Absperrorgans nicht mehr bedarf. Bei Spritzpistolen neuester Konstruktion, z. B. bei den sogenannten Industriepistolen, sind bekanntlich zwei Druckluftanschlüsse vorgesehen, um den Schlauch sowohl von unten als auch von hinten her an die Pistole anschließen zu können. Gerade für solche Geräte ist die Erfindung besonders geeignet. Gemäß der Zeichnung ist beispielsweise am Handgriff i der nicht dargestellten Spritzpistole die eine Kupplungshälfte 2a eines an sich bekannten, sich selbsttätig schließenden Druckluftschlauchverbinders befestigt, dessen andere Hälfte mit 2b gezeigt ist. An letzterer befindet sich unter Zwischenschaltung eines Gewindes 3a der Schlauchnippel 3, mit dem der Druckluftschlauch q. durch Nachoben- bzw. Nachuntenschrauben der Kupplungsmuffe 5 in an sich bekannter Weise leicht los- bzw. festgekuppelt werden kann.According to the invention, one coupling half is located on the spray gun a known, automatically closing compressed air hose connector, the other half of which is combined with the hose nipple via a hose coupling is. Apart from the fact that the previous makeshift through the existing hose coupling Jamming of the hose on the nipple is avoided by the invention of the Advantage achieved that; For example, if one spray gun is exchanged for another is to be, the hose together with the disengaged one coupling half from one pistol and onto the other pistol needs to be attached. The compressed air is in the uncoupled state automatically turned off, so that there is a special actuation of a shut-off device no longer needed. In the case of spray guns of the latest design, e.g. B. in the so-called Industrial guns, as is known, two compressed air connections are provided to the Connect the hose to the gun both from below and from behind can. The invention is particularly suitable for such devices. According to the Drawing is for example on the handle i of the spray gun, not shown the one coupling half 2a of a known, self-closing Fastened compressed air hose connector, the other half of which is shown with 2b. The hose nipple is located on the latter with a thread 3a interposed 3 with which the compressed air hose q. by screwing the Coupling sleeve 5 can be easily loosened or coupled tightly in a manner known per se can.

Wenn z. B. mit verschiedenen Mitteln gespritzt werden soll, wozu verschiedene, mit den jeweils erforderlichen Spritzmitteln gefüllte Pistolen notwendig sind, braucht also nur die Kupplungshälfte 2b von der Hälfte 2a durch Verschieben der äußeren Kupplungshülse losgekuppelt und auf das Teil 2a der jeweils anderen Pistole umgesteckt zu werden, wobei die Druckluft in an sich bekannter Weise selbsttätig ab- bzw. angestellt wird.If z. B. is to be injected with different agents, including different, guns filled with the required spraying agents are necessary so only the coupling half 2b of the half 2a by moving the outer one Coupling sleeve uncoupled and repositioned on part 2a of the other pistol to be, with the compressed air automatically switched off or on in a manner known per se will.
