Abstract
Description
Die Erfindung betrifft einen Farbbecher für eine Fließbecher-Farbspritzpistole nach dem Oberbegriff des Anspruchs 1.The The invention relates to a paint cup for a gravity cup spray gun the preamble of claim 1.
Aus
dem Stand der Technik, beispielsweise der
Zum Einbringen der Belüftungsöffnung in die Behälterwand ist ein separates Spitzwerkzeug, beispielsweise eine Nadel oder ein Dorn, erforderlich. Ein solches Werkzeug ist häufig nicht jederzeit verfügbar. Weiterhin erweist sich das Durchstoßen der regelmäßig aus Hartkunststoff bestehenden Behälterwand auch mit einem geeigneten Spitzwerkzeug als schwierig. Darüber hinaus besteht die Gefahr, dass durch das Eindrücken einer Öffnung in die Behälterwand Kunststoffspäne oder -teile in den mit Farbe gefüllten Farbbecher fallen.To the Inserting the ventilation opening in the container wall is a separate point tool, such as a needle or a thorn, required. Such a tool is often not available at any time. Furthermore, the piercing of regularly proves Hard plastic existing container wall even with a suitable pointed tool as difficult. Furthermore There is a risk that by pressing an opening in the container wall Plastic chips or parts in the color filled Paint cup falling.
Ferner sind aus dem Stand der Technik, z.B. aus der WO 98/32539, Ventilanordnungen bekannt, bei denen sich an dem Farbbecher oder seinem Deckel ein Ventil befindet. Dieses kann geschlossen werden, beispielsweise um ein Austrocknen der Farbe zu verhindern, und geöffnet werden, um einen Druckausgleich während des Farbspritzens zu ermöglichen, also den durch den Verbrauch der Farbe in dem Fließbecher entstehenden Unterdruck auszugleichen. Diese Ventilanordnungen weisen den Nachteil auf, dass sie manuell betätigt werden müssen, wobei leicht vergessen werden kann, dass das Ventil noch geschlossen ist und dann während des Spritzens plötzlich keine Farbe mehr nachläuft oder umgekehrt vergessen werden kann, dass das Ventil noch geöffnet ist und der Behälter beim Abstellen dann ausläuft.Further are known in the art, e.g. from WO 98/32539, valve arrangements known in which a color cup or its lid Valve is located. This can be closed, for example to prevent the paint from drying out and being opened, to equalize the pressure during to allow the paint spraying So by the consumption of color in the flow cup compensate for the resulting negative pressure. These valve arrangements have the disadvantage that they must be operated manually, where It is easy to forget that the valve is still closed and then while the splash suddenly no more color runs after or vice versa can forget that the valve is still open and the container when parking then expires.
Ferner
sind aus dem Stand der Technik im Zusammenhang mit Farbspritzpistolen
Ventilanordnungen bekannt, beispielsweise ein in der
Es besteht daher die Aufgabe, einen Fließbecher für eine Farbspritzpistole so weiterzubilden, dass der Benutzer nicht vergessen kann, das Ventil entsprechend den momentanen Arbeitsbedürfnissen einzustellen.It There is therefore the task of a gravity cup for a paint spray gun so educate that the user can not forget the valve accordingly to cease the current work needs.
Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.Is solved This object with the characterizing features of claim 1. Advantageous embodiments are the dependent claims.
Einige Ausführungsbeispiele der Erfindung werden im folgenden unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert. Dabei zeigen:Some embodiments The invention will be described below with reference to the accompanying drawings Drawings closer explained. Showing:

Anordnung funktioniert genauso wie diejenigen gemäß
In einer alternativen, nicht dargestellten Ausführungsform der Erfindung kann lediglich ein flexibler Abschnitt vorgesehen sein, der sich über eine Öffnung in dem Farbbecher erstreckt, wobei es sich hier nicht um eine Abdeckung als zusätzliches Bauteil handeln muss, sondern dieser flexible Abschnitt auch zusammen mit dem Farbbecher selbst ausgeformt sein kann. Auch bei dieser nicht dargestellten Ausführungsform dichtet der flexible Abschnitt bei Druckausgleich gas- und flüssigkeitsdicht ab während er bei einem Unterdruck im Behälterinnern eine Öffnung freigibt und damit einen Druckausgleich ermöglicht. Nach erfolgtem Druckausgleich bewegt sich der flexible Abschnitt jedoch aufgrund seiner eigenen Elastizität wieder in die Ursprungsstellung zurück und dichtet den Farbbecher ab.In an alternative, not shown embodiment of the invention can only a flexible portion may be provided which extends over an opening in extends the paint cup, which is not a cover as additional Component must act, but this flexible section also together can be formed with the paint cup itself. Also with this not shown embodiment seals the flexible section with pressure equalization gas and liquid tight off during he at a negative pressure in the container interior an opening releases and thus allows pressure equalization. After pressure equalization However, the flexible section moves due to its own elasticity back to the original position and seals the paint cup from.

Gegenstand der Erfindung ist schließlich eine Fließbecher-Farbspritzpistole, welche einen Farbbecher aufweist, wie er in den vorangehenden Ausführungsbeispielen im einzelnen beschrieben wurde.object Finally, the invention is a Gravity cup spray gun, which has a color cup, as in the preceding embodiments has been described in detail.
