Description

Die Erfindung betrifft eine Verwendung eines Bechers als Fließbecher für eine Farbspritzpistole nach dem Oberbegriff des Anspruchs 1. Eine solche Verwendung ist durch das Dokument US.2004/0140373 bekannt.The invention relates to a use of a cup as a flow cup for a paint spray gun according to the preamble of claim 1. Such use is by the document US.2004 / 0140373 known.

Herkömmliche Fließbecher für Farbspritzpistolen weisen in der Regel einen becherförmigen Behälter auf, an dessen Unterseite eine Öffnung mit einem Anschlussteil zur lösbaren Befestigung des Behälters auf der Oberseite der Farbspritzpistole vorgesehen ist. Das Anschlussteil besteht üblicherweise aus einem am Behälterboden angeordneten Anschlussstutzen, der ein Außengewinde zum Einschrauben in eine entsprechende Gewindeöffnung an der Oberseite der Farbspritzpistole aufweist. Bei den bekannten Fließbechern ist der Anschlussteil in der Regel starr an dem Behälter angeordnet. Dadurch ergibt sich jedoch das Problem, dass der auf die Farbspritzpistole aufgesetzte Behälter bei bestimmten Schrägstellungen der Farbspritzpistole eine horizontale oder nahezu horizontale Stellung einnimmt und dann die Zuführung der Farbe zur Farbspritzpistole unter Umständen nicht mehr gewährleistet ist.Conventional gravity cups for paint spray guns usually have a cup-shaped container, on the underside of an opening with a connector for releasably securing the container is provided on the top of the paint spray gun. The connecting part usually consists of a container base arranged on the connecting piece, which has an external thread for screwing into a corresponding threaded opening at the top of the paint spray gun. In the known fluid buckets of the connecting part is usually arranged rigidly on the container. However, this results in the problem that the patch on the spray gun container at certain inclinations of the paint spray gun occupies a horizontal or almost horizontal position and then the supply of the color to the spray gun may no longer be guaranteed.

Aufgabe der Erfindung ist es, eine Verwendung eines Bechers als Fließbecher für eine Farbspritzpistole der eingangs genannten Art zu verbesseren, wobei eine verbesserte Materialzuführung auch bei Schrägstellungen der Farbspritzpistole ermöglicht ist.The object of the invention is to improve the use of a cup as a flow cup for a paint spray gun of the type mentioned, with an improved material supply is made possible even at inclinations of the paint spray gun.

Diese Aufgabe wird durch eine Verwendung eines Bechers als Fließbecher für eine Farbspritzpistole mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a use of a cup as a flow cup for a paint spray gun with the features of claim 1. Advantageous embodiments and advantageous developments of the invention are the subject of the dependent claims.

Ein wesentlicher Vorteil der erfindungsgemäßen Verwendung eines Bechers als Fließbechers für eine Farbspritzpistole besteht darin, dass der Farbbehälter relativ zum Anschlussteil gekippt werden kann. Die Neigung des auf die Farbspritzpistole aufgesetzten Fließbechers kann so bei Bedarf verändert werden, um so den Zufluss der Farbe zur Farbspritzpistole auch bei größeren Schrägstellungen der Farbspritzpistole zu gewährleisten. Die Verstellmöglichkeit wird dadurch erreicht, dass ein Übergangsbereich zwischen dem Anschlussteil und dem Behälter oder dem Deckel flexibel ausgebildet ist. Der Anschlussteil zur lösbaren Befestigung des Fließbechers an der Farbspritzpistole kann an dem Behälter oder auch an dem Deckel angebracht sein. Wenn sich der Anschlussteil an dem Deckel befindet, steht der Behälter in seiner Einsatzstellung auf dem Kopf.A significant advantage of the use according to the invention of a cup as a flow cup for a paint spray gun is that the ink container can be tilted relative to the connection part. The inclination of the attached to the paint spray gun fluid can be changed if necessary, so as to ensure the inflow of color to the paint spray gun even with larger inclinations of the paint spray gun. The adjustment is achieved in that a transition region between the connection part and the container or the lid flexible is trained. The connection part for the detachable attachment of the flow cup to the paint spray gun may be attached to the container or on the lid. When the connector is on the lid, the container is in its use position on the head.

In einer fertigungstechnisch einfachen Ausführung der Erfindung ist am Übergangsbereich zwischen dem Anschlussteil und dem Behälter oder dem Deckel ein Wandstärkenübergang von einer dickeren Wandstärke am Anschlussteil in eine dünnere Wandstärke am Behälter oder Deckel vorgesehen.In a manufacturing technology simple embodiment of the invention, a wall thickness transition is provided by a thicker wall thickness at the connection part in a thinner wall thickness on the container or lid at the transition region between the connection part and the container or the lid.

In einer weiteren Ausgestaltung kann der Übergangsbereich aber auch z.B. in Art eines Faltenbalgs oder dgl. ausgeführt sein.In a further embodiment, however, the transition region may also be e.g. be executed in the manner of a bellows or the like.

Weitere Besonderheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung. Es zeigen:

Other features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings. Show it:
FIG. 1
a first embodiment of a flow cup, which is suitable for the use according to the invention, with a straight and a tilted connection part and enlarged representations of the areas X and Y;
FIG. 2
a second embodiment of a flow cup, which is suitable for the use according to the invention, with a straight and a tilted connection part and enlarged representations of the areas X and Y.

Die in den Figuren 1 und 2 dargestellten Fließbecher für eine Farbspritzpistole enthalten einen becherförmigen Behälter 1, einen auf den Behälter 1 aufsetzbaren Deckel 2 und einen an dem Behälter 1 angeformten Anschlussteil 3 zur lösbaren Befestigung des Behälters 1 an einer Farbspritzpistole. Sowohl der Behälter 1 mit dem angeformten Anschlussteil 3 als auch der Deckel 2 sind als Spritzgussteile aus einem elastischen, nicht versprödenden Kunststoffmaterial hergestellt. Diese Anforderungen erfüllen z.B. Kunststoffe aus PE oder solche, die hohe PE-Anteile enthalten.The in the FIGS. 1 and 2 illustrated flow cup for a paint spray gun containing a cup-shaped container 1, a can be placed on the container 1 cover 2 and a molded onto the container 1 connecting part 3 for releasably securing the container 1 to a paint spray gun. Both the container 1 with the integrally formed connection part 3 and the cover 2 are produced as injection-molded parts from an elastic, non-embrittling plastic material. These requirements are met, for example, by plastics made of PE or those containing high PE content.

Wie besonders aus den vergrößerten Detailansichten X und Y der Figuren 1 und 2 hervorgeht, besteht der Anschlussteil 3 aus einem an den konischen Boden 4 des Behälters 1 angespritzten oder anderweitig angeformten, rohrförmigen Anschlussstutzen, der einen vorderen hohlzylindrischen Führungsbereich 5, ein daran anschließendes Außengewinde 6 zum Einschrauben in ein konventionelles Innengewinde, ein oberhalb des Außengewindes 6 angeordnetes Schraubkeilelement für eine Schnellverbindung des Fließbechers mit der Farbspritzpistole und einen oberen Einsatzbereich 7 mit einer inneren ringförmigen Anlagefläche 8 zum Einstecken eines an sich bekannten Filters enthält. Bei der gezeigten Ausführung wird das Schraubkeilelement durch einen etwa über die Hälfte des Umfangs des Anschlussteil 3 verlaufenden schraubkeilförmigen Vorsprung 9 mit einer Schraubkeilfläche 10 gebildet, die in Eingriff mit einer entsprechenden Gegenfläche an einem Ansatz oder Vorsprung der Farbspritzpistole gelangt. Der Vorsprung 9 mit der Schraubkeilfläche 10 und die entsprechende Gegenfläche an der Farbspritzpistole sind so ausgebildet, dass der Behälter 1 bereits mit einer viertel bis halben Umdrehung dicht an der Farbspritzpistole befestigt werden kann. Der Anschlussteil 3 wird hierzu mit seiner vorderen Stirnfläche 11 an eine entsprechende Dichtfläche innerhalb der Farbspritzpistole angezogen. Über das zusätzliche Außengewinde 6 kann der Fließbecher auch für Farbspritzpistolen verwendet werden, die keinen zu dem Schraubkeilelement passenden Anschluss, jedoch einen herkömmlichen Innengewindeanschluss aufweisen.As especially from the enlarged detail views X and Y of FIGS. 1 and 2 It can be seen that the connecting part 3 consists of a molded onto the conical bottom 4 of the container 1 or otherwise molded tubular connecting piece, a front hollow cylindrical guide portion 5, an adjoining external thread 6 for screwing into a conventional internal thread, above the external thread 6 arranged Schraubkeilelement for a quick connection of the flow cup with the paint spray gun and an upper insert portion 7 with an inner annular abutment surface 8 for insertion of a filter known per se. In the embodiment shown, the Schraubkeilelement is formed by an approximately over half of the circumference of the connecting part 3 extending wedge-shaped projection 9 with a Schraubkeilfläche 10 which engages with a corresponding mating surface on a lug or projection of the paint spray gun. The projection 9 with the Schraubkeilfläche 10 and the corresponding mating surface on the paint spray gun are designed so that the container 1 can already be attached with a quarter to half turn close to the paint spray gun. For this purpose, the connection part 3 is attracted with its front end face 11 to a corresponding sealing surface within the paint spray gun. Via the additional external thread 6, the flow cup can also be used for paint spray guns, which have no mating to the Schraubkeilelement connection, but a conventional female thread connection.

Bei den in Figur 1 und 2 dargestellten Fließbechern ist ein Übergangsbereich 12 zwischen dem Anschlussteil 3 und dem Boden 4 des Behälters 1 flexibel ausgebildet, so dass eine Verstellung der Winkellage der Mittelachse 13 des Behälters 1 relativ zur Mittelachse 14 des Anschlussteils 3 ermöglicht wird. Der Übergangsbereich 12 ist dabei so gestaltet, dass der Behälter 1 nach dem Aufschrauben auf eine Farbspritzpistole bei Bedarf in eine gewünschte Kippstellung gebracht werden kann und aus dieser auch nicht selbsttätig in seine Normalstellung zurückschwenkt. Falls erforderlich, kann der Behälter 1 jedoch wieder in seine Normalstellung oder in andere Kippstellung verschwenkt werden. In den jeweils linken Darstellungen der Figuren 1 und 2 ist der Fließbecher in seiner Normalstellung gezeigt. In dieser Stellung fällt die Mittelachse 13 des Behälters 1 mit der Mittelachse 14 des Anschlussteils 3 zusammen. In den jeweils rechten Darstellungen ist der Behälter 1 gegenüber dem Anschlussteil 3 gekippt. Die Mittelachse 14 des Anschlussteils 3 ist dann unter einem Winkel zur Mittelachse 13 des Behälters 1 geneigt.At the in FIG. 1 and 2 shown flow cups is a transition region 12 between the connecting part 3 and the bottom 4 of the container 1 is flexible, so that an adjustment of the angular position of the central axis 13 of the container 1 relative to the central axis 14 of the connecting part 3 is made possible. The transition region 12 is designed so that the container 1 can be brought after screwing on a paint spray gun when needed in a desired tilted position and from this also does not swing back automatically into its normal position. If necessary, the container 1, however, can be pivoted back to its normal position or in another tilted position. In each left representations of FIGS. 1 and 2 the flow cup is shown in its normal position. In this position, the central axis 13 of the container 1 coincides with the central axis 14 of the connecting part 3. In the respective right representations of the container 1 is tilted relative to the connection part 3. The central axis 14 of the connecting part 3 is then inclined at an angle to the central axis 13 of the container 1.

Im Ausführungsbeispiel von Figur 1 ist der Übergangsbereich 12 zwischen dem Anschlussteil 3 und dem Behälter 1 derart gestaltet, dass ein Wandstärkenübergang von einer dickeren Wandstärke am Einsatzbereich 7 des Anschlussteils 3 in eine dünnere Wandstärke des Behälterbodens 4 vorgesehen ist. Der Wandstärkenunterschied am Übergangsbereich beträgt mindestens 30%. Dadurch wird sichergestellt, dass der Boden 4 des Behälters 1 auch ohne Entstehung von Rissen gebogen werden kann, der Einsatzbereich 7 des Anschlussteils 3 dabei jedoch nicht beeinträchtigt wird. Dadurch wird der Innenkontur des Anschlussteils 3 zur Aufnahme des Filters auch beim Verschwenken des Behälters 1 beibehalten. An dem Übergang von dem Anschlussteil 3 in den Boden 4 des Behälters 1 ist ein Radius 15 vorgesehen. Dadurch wird gewährleistet, dass der Behälter 1 in diesem Bereich beim Kippen keinen Schaden erleidet bzw. einknickt.In the embodiment of FIG. 1 the transition region 12 between the connection part 3 and the container 1 is designed such that a wall thickness transition is provided by a thicker wall thickness at the application region 7 of the connection part 3 in a thinner wall thickness of the container bottom 4. The wall thickness difference at the transition area is at least 30%. This ensures that the bottom 4 of the container 1 can be bent even without the formation of cracks, but the application area 7 of the connection part 3 is not impaired. As a result, the inner contour of the connection part 3 for receiving the filter is also maintained during pivoting of the container 1. At the transition from the connection part 3 in the bottom 4 of the container 1, a radius 15 is provided. This ensures that the container 1 suffers no damage or buckling when tilted in this area.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel ist der Übergangsbereich 12 in Art eines Faltenbalgs ausgebildet. Auch bei dieser Ausführung kann der Behälter 1 bei Bedarf gegenüber dem Anschlussteil 3 gekippt werden.At the in FIG. 2 illustrated embodiment, the transition region 12 is formed in the manner of a bellows. Also in this embodiment, the container 1 can be tilted when needed relative to the connection part 3.

Die Erfindung ist nicht auf die vorstehend beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiele beschränkt. So kann der Anschlussteil 3 auch an dem Deckel angeformt sein. Der Behälter kann dann eine übliche Becherform mit einer geraden Bodenfläche ohne Anschlussteil aufweisen. Der mit dem Anschlussteil versehene Deckel kann nach dem Befüllen des Behälters auf diesen aufgesetzt werden und der Fließbecher kann dann in die Anschlussöffnung einer auf den Kopf gestellten Farbspritzpistole eingesetzt werden. Zum Spritzen kann dann die Farbspritzpistole anschließend umgedreht werden, so dass sich der Fließbecher an der Oberseite der Farbspritzpistole befindet. Um eine Entlüftung des Fließbechers zu ermöglichen, kann z.B. ein am Boden des Fließbechers vorgesehenes Entlüftungsventil geöffnet oder ein zunächst geschlossener Entlüftungskanal mit Hilfe eines Stifts oder dgl. durchstoßen werden. Durch ein nach Gebrauch wieder verschließbares Entlüftungsventil oder eine wieder verschließbare Entlüftungsöffnung ergibt sich der Vorteil, dass der Fließbecher auch zur Aufbewahrung nicht vollständig aufgebrauchter Farbe verwendet werden kann.The invention is not limited to the embodiments described above and shown in the drawing. Thus, the connection part 3 may also be formed on the lid. The container may then have a conventional cup shape with a straight bottom surface without connecting part. The lid provided with the connection part can be placed on this after filling of the container and the flow cup can then be inserted into the connection opening of an upside-down paint spray gun. For spraying then the paint spray gun can then be reversed, so that the flow cup is located on the top of the paint spray gun. In order to allow venting of the flow cup, e.g. a vent valve provided at the bottom of the fluid cup is opened, or an initially closed vent channel is pierced by means of a pin or the like. By a reclosable after use bleed valve or a reclosable vent, there is the advantage that the flow cup can also be used to store not completely used up color.
