Description

Die vorliegende Erfindung betrifft ein Spritzpistolensystem, umfassend eine Spritzpistole zum Abgeben eines Spritguts, an der ein Spritzgutaufnahmebehälter befestigbar ist; eine Basisvorrichtung mit einem Gehäuse, in dem eine Drucklufterzeugungseinrichtung aufgenommen ist; und einen Druckluftschlauch, der an die Spritzpistole und an die Basisvorrichtung anschließbar ist, um diese miteinander zu verbinden.The present invention relates to a spray gun system comprising a spray gun for dispensing a Spritguts to which a Spritzgutaufnahmebehälter is attachable; a base device with a housing in which a compressed air generating device is accommodated; and a compressed air hose connectable to the spray gun and the base device to connect them together.

Spritzpistolensysteme der zuvor genannten Art sind im Stand der Technik in verschiedensten Ausgestaltungen bekannt, siehe hierzu beispielsweise die Druckschriften GB-A-347 161 , DE-U-20 2007 007 256 , WO 01/24941 A , EP-A-1 393 824 oder WO 2007/041770 A . Mit derartigen Spritzpistolensystemen kann Spritzgut verspritzt werden, insbesondere mit Wasser verdünnbares und lösungsmittelhaltiges Spritzgut, wie beispielsweise Farben, Lacke, Lasuren, Grundierungen, Beizen und Holzschutzmittel, um nur einige zu nennen. Als Spritzverfahren kommt meist das Niederdruck-Spritzverfahren zur Anwendung, bei dem es sich um ein Verfahren handelt, bei dem Spritzgut bei einem geringen Druck von etwa 0,2 bis etwa 0,5 bar und mit einem hohen Luftvolumen ab etwa 200 Liter pro Minute verspritzt wird. Dieses HVLP-Spritzverfahren erreicht wegen des geringen Überspritzens, d.h. wegen seiner geringen Sprühnebelverluste, Beschichtungsgrade bis etwa 65% und ist somit herkömmlichen Verfahren, die Beschichtungsgrade zwischen etwa 20 und etwa 35% erzielen, überlegen. Kennzeichnend für das Verfahren ist der das Spritzgut umgebende Luftkegel, der ein Überspritzen und eine Farbnebelbildung verringert. Damit ergeben sich Vorteile wie Lackeinsparung und geringe Lösungsmittelemissionen, die sich besonders umweltschonend auswirken.Spray gun systems of the aforementioned type are known in the prior art in a variety of configurations, see for example the publications GB-A-347161 . DE-U-20 2007 007 256 . WO 01/24941 A . EP-A-1 393 824 or WO 2007/041770 A , Sprays can be sprayed with spray gun systems of this kind, in particular water-dilutable and solvent-containing sprayed material, such as, for example, paints, lacquers, glazes, primers, stains and wood preservatives, to name only a few.

Derartige Spritzpistolensysteme umfassen normalerweise eine Basisvorrichtung mit einem Gehäuse, in dem eine Drucklufterzeugungseinrichtung aufgenommen ist, welche die zum Verspritzen des Spritzguts erforderliche Druckluft generiert. Die Drucklufterzeugungseinrichtung der Basisvorrichtung ist über einen Druckluftschlauch mit einer Spritzpistole verbunden, die als Handgerät ausgebildet ist und mit deren Hilfe das Spritzgut aufgetragen werden kann. Die Spritzpistole umfasst ein Gehäuse, an dem ein Handgriff ausgebildet ist, eine Halteeinrichtung zur Aufnahme eines Spritzgutaufnahmebehälters sowie eine Spritzdüse, durch die das Spritzgut unter Druck abgegeben wird.Such spray gun systems normally comprise a base device with a housing, in which a compressed air generating device is accommodated, which generates the compressed air required for spraying the injection molding. The compressed air generating device The base device is connected via a compressed air hose with a spray gun, which is designed as a hand-held device and with the aid of which the sprayed material can be applied. The spray gun comprises a housing on which a handle is formed, a holding device for receiving a Spritzgutaufnahmebehälters and a spray nozzle through which the sprayed material is delivered under pressure.

Während des Betriebs des Spritzpistolensystems wird der von der Drucklufterzeugungseinheit erzeugte Druckluftstrom durch den Druckluftschlauch in den an der Spritzpistole gehaltenen Spritzgutaufnahmebehälter geleitet. Ein Teil des Druckluftstroms fördert das in dem Spritzgutaufnahmebehälter enthaltene Spritzgut nach Betätigung eines an der Spritzpistole angeordneten Bedienhebels aus dem Spritzgutaufnahmebehälter und wird durch die Spritzdüse abgegeben. Der restliche Teil des Druckluftstroms gelangt über rund um die Spritzdüse verteilte Öffnungen ins Freie, und zwar in Form eines Luftkegels, der das Spritzgut umhüllt. Mit Hilfe dieses Luftkegels wird die Farbnebelbildung wesentlich verringert.During operation of the spray gun system, the compressed air flow generated by the compressed air generating unit is passed through the compressed air hose in the spray material receiving container held on the spray gun. A portion of the compressed air flow conveys the sprayed material contained in the sprayed goods container after actuation of an operating lever arranged on the spray gun from the sprayed goods receiving container and is discharged through the spray nozzle. The remaining part of the compressed air flow passes through openings distributed around the spray nozzle into the open air, in the form of an air cone, which envelops the sprayed material. With the help of this air cone, the color fog is significantly reduced.

Ein Problem bei solchen Spritpistolensystemen besteht dahingehend, dass insbesondere die Basisvorrichtung aufgrund ihres relativ hohen Gewichts nur schlecht zu bewegen und zu transportieren ist.A problem with such gas pistol systems is that, in particular, the base device is difficult to move and transport due to its relatively high weight.

Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, ein Spritzpistolensystem der eingangs genannten Art mit einem alternativen Aufbau zu schaffen, der die Handhabung des Systems und insbesondere der Basisvorrichtung desselben erleichtert.Based on this prior art, it is an object of the present invention to provide a spray gun system of the type mentioned above with an alternative structure, which facilitates the handling of the system and in particular the basic device thereof.

Offenbarung der ErfindungDisclosure of the invention

Zur Lösung dieser Aufgabe schafft die vorliegende Erfindung ein Spritzpistolensystem, umfassend eine Spritzpistole zum Abgeben eines Spritzguts, an der ein Spritzgutaufnahmebehälter, befestigbar ist; eine Basisvorrichtung mit einem Gehäuse, in dem eine Drucklufterzeugungseinrichtung aufgenommen ist; und einen Druck luftschlauch, der an die Spritzpistole und an die Basisvorrichtung anschließbar ist, um diese miteinander zu verbinden. Ferner weist das Gehäuse der Basisvorrichtung eine Transporteinrichtung auf, die derart beschaffen ist, dass sie ein Bewegen und Transportieren der Basisvorrichtung und somit eine Handhabung des Spritzpistölensystems erleichtert.To achieve this object, the present invention provides a spray gun system comprising a spray gun for dispensing an injection molding, to which a Spritzgutaufnahmebehälter, can be fastened; a base device with a housing in which a compressed air generating device is included; and a pressure air hose, which is connectable to the spray gun and the base device to connect them together. Furthermore, the housing of the base device has a transport device, which is designed such that it facilitates a moving and transporting the base device and thus a handling of the spray gun system.

Vorteilhaft umfasst die Transporteinrichtung ein Fahrwerk mit zumindest zwei Rollkörpern, die an der Unterseite des Gehäuses angeordnet sind: So können beispielsweise zwei Rollkörper, bei denen es sich um Räder, Kugeln, Walzen oder dergleichen handeln kann, am hinteren Gehäusebereich an der Gehäuseunterseite positioniert sein, so dass sich die Basisvorrichtung auf den Rollen über einen Untergrund bewegen lässt, indem sie einfach gezogen oder leicht gekippt wird, so dass sie ausschließlich auf den Rollkörpern ruht. Dabei kann für jeden Rollkörper eine separate Drehachse vorgesehen sein, wobei die Drehachsen in diesem Fall bevorzugt miteinander fluchten. Alternativ können die Rollkörper aber auch auf einer gemeinsamen Drehachse angeordnet sein.Advantageously, the transport device comprises a chassis with at least two rolling bodies which are arranged on the underside of the housing: Thus, for example, two rolling bodies, which may be wheels, balls, rollers or the like, may be positioned on the rear housing area on the underside of the housing, so that the base device can be moved on the rollers on a ground by simply pulled or slightly tilted, so that it rests exclusively on the rolling elements. In this case, a separate axis of rotation may be provided for each rolling body, wherein the axes of rotation are preferably aligned with each other in this case. Alternatively, however, the rolling bodies can also be arranged on a common axis of rotation.

Gemäß einer Ausgestaltung der vorliegenden Erfindung ist an der Unterseite des Gehäuses zumindest eine Stütze angeordnet ist, die gemeinsam mit dem Fahrwerk eine Standfläche für das Gehäuse bildet. Dabei sind das Fahrwerk und die zumindest eine Stütze vorteilhaft möglichst weit voneinander beabstandet, um auf diese Weise eine standfeste Dreipunktlagerung zu erzielen. Die zumindest eine Stütze ist dabei vorteilhaft einteilig mit dem Gehäuse ausgebildet. Entsprechend ergibt sich ein Aufbau mit wenigen Bauteilen, der sich leicht herstellen und montieren lässt. Es sollte klar sein, dass natürlich auch mehr als eine Stütze vorgesehen werden können.According to one embodiment of the present invention, at least one support is arranged on the underside of the housing, which forms a base for the housing together with the chassis. In this case, the chassis and the at least one support advantageously as far as possible from each other to achieve a stable three-point storage in this way. The at least one support is advantageously formed integrally with the housing. Accordingly, there is a structure with few components that can be easily manufactured and assembled. It should be clear that, of course, more than one support can be provided.

Gemäß einer alternativen Ausgestaltung weist das Fahrwerk anstelle der zumindest einen Stütze wenigstens einen weiteren Rollkörper auf, der bevorzugt mittig zwischen den zuvor beschrieben beiden Rollkörpern und versetzt zu diesen angeordnet ist, wodurch ebenfalls eine standfeste Dreipunktlagerung erzeugt wird. Dabei ist die Drehachse des zumindest einen weiteren Rollkörpers vorteilhaft verschwenkbar angeordnet, wodurch ein gut lenkbares Fahrwerk erzeugt wird.According to an alternative embodiment, instead of the at least one support, the chassis has at least one further rolling body, which preferably is located centrally between the previously described two Rolling bodies and offset to these is arranged, which also produces a stable three-point bearing. In this case, the axis of rotation of the at least one further rolling body is advantageously arranged pivotably, whereby a well steerable chassis is generated.

Vorteilhaft verfügt das Fahrwerk über eine Bremse, mit zumindest einer der Rollkörper wahlweise blockierbar ist, um ein unbeabsichtigtes Rollen zu verhindern.Advantageously, the suspension has a brake, with at least one of the rolling elements is selectively blocked to prevent accidental roles.

An dem Gehäuse der Basisvorrichtung ist bevorzugt ein Ausziehgriff angeordnet, der zum Transport der Basisvorrichtung bei Bedarf ausgezogen werden kann. Auf diese Weise kann die Basisvorrichtung ähnlich wie ein Koffer auf dem Fahrwerk ruhend manövriert werden. Der Ausziehgriff ist dabei vorteilhaft derart beschaffen, dass er in verschiedenen Ausziehpositionen bzw. Ausziehlängen arretiert werden kann, um die Länge des Ausziehgriffes an die Größe eines Benutzers anpassen zu können.On the housing of the base device, a pull-out handle is preferably arranged, which can be pulled out to transport the base device if necessary. In this way, the base device can be maneuvered like a suitcase resting on the landing gear. The pull-out handle is advantageously such that it can be locked in different pull-out positions or pull-out lengths in order to be able to adapt the length of the pull-out handle to the size of a user.

Ferner ist an dem Gehäuse der Basisvorrichtung zumindest eine Stützeinrichtung vorgesehen, die im aufrecht stehenden Zustand des Gehäuses eine Standfläche bildet, welche die Basisvorrichtung auf einem Untergrund abstützt. Die zumindest eine Stützeinrichtung ist erfindungsgemäß schwenkbar an dem Gehäuse angeordnet und zumindest zwischen einer Stützposition, in der sie die mit einem Untergrund in Kontakt kömmende Auflagefläche bildet, und einer zurückgezogenen Position verschwenkbar. Entsprechend kann ein Benutzer die Stützeinrichtung bei Bedarf in ihre Stützposition bewegen. Ansonsten kann die Stützeinrichtung in ihrer zurückgezogenen Position angeordnet werden, in der sie bevorzugt in dem Gehäuse der Basisvorrichtung aufgenommen ist oder an diesem anliegt, so dass sie keinen Störfaktor bildet und in das Gesamtdesign des Basisvorrichtungsgehäuses integriert ist. Diesbezüglich weist die Stützeinrichtung bevorzugt zumindest ein Vorspannelement auf, dass die Stützeinrichtung in ihre zurückgezogene Position vorspannt.Further, at least one support means is provided on the housing of the base device, which forms a standing surface in the upright state of the housing, which supports the base device on a substrate. The at least one support device according to the invention is pivotally mounted on the housing and pivotable at least between a support position in which it forms the contact surface coming into contact with a substrate, and a retracted position. Accordingly, a user can move the support device to its supporting position as needed. Otherwise, the support means may be disposed in its retracted position in which it is preferably received in or in contact with the housing of the base device, so that it does not interfere and is integrated into the overall design of the base device housing. In this regard, the support means preferably includes at least one biasing member that biases the support means to its retracted position.

Zudem umfasst die Transporteinrichtung gemäß der vorliegenden Erfindung vorteilhaft einen an dem Gehäuse der Basisvorrichtung ausgebildeten Handgriff. Während das Fahrwerk zum Bewegen der Basisvorrichtung über einen im Wesentlichen ebenen Untergrund dient, kann ein Benutzer das Basisvorrichtungsgehäuse auch wahlweise an diesem Handgriff hochheben, um die Basisvorrichtung über unebenes Gelände zu tragen, wie beispielsweise Treppen oder dergleichen. Der Handgriff ist bevorzugt als Griffmulde ausgebildet. Eine Griffmulde hat gegenüber einem von dem Gehäuse abstehenden Handgriff den Vorteil, dass sie näher an dem Schwerpunkt der Basisvorrichtung angeordnet werden kann, so dass sich diese einfacher handhaben lässt. Zudem kann bei der Verwendung einer Griffmulde gegenüber einem vom Gehäuse abstehenden Handgriff Material eingespart werden. Die Griffmulde ist bevorzugt an der Unterseite des Gehäuses vorgesehen, so dass sie das Gesamtdesign der Basisvorrichtung kaum beeinträchtigt.In addition, the transport device according to the present invention advantageously comprises a handle formed on the housing of the base device. While the landing gear is for moving the base apparatus over a substantially level ground, a user may also selectively lift the base apparatus body on that handle to support the base apparatus over rough terrain such as stairs or the like. The handle is preferably designed as a recessed grip. A recessed grip has the advantage over a handle protruding from the housing that it can be arranged closer to the center of gravity of the base device so that it can be handled more easily. In addition, when using a recessed grip against a protruding from the housing material can be saved. The recessed grip is preferably provided on the underside of the housing, so that it hardly affects the overall design of the base device.

Das Spritzpistolensystem 10 umfasst eine Basisvorrichtung 12 mit einem Gehäuse 14, in dem eine nicht dargestellte Drucklufterzeugungseinrichtung aufgenommen ist. An dem hinteren Teil der Unterseite 15 des Gehäuses 14 sind zwei Rollkörper in Form von Rädern 16 aufgenommen, so dass die Basisvorrichtung 12 nach Art eines Staubsaugers über einen Untergrund bewegt werden kann. Die Räder 16 sind mit Hilfe einer nicht dargestellten Bremse wahlweise blockierbar, um ein ungewolltes Rollen zu verhindern. An dem vorderen Teil der Unterseite 15 des Gehäuses 14 sind vorsprungartige Stützen 18 vorgesehen, die zusammen mit den Rädern 16 die Auflagefläche des Gehäuses 14 bilden, wie es am besten in Fig. 2 zu erkennen ist. Anstelle der Stützen 18 kann auch ein mittig an dem vorderen Teil der Unterseite 15 des Gehäuses 14 angeordnetes, verschwenkbares und somit lenkbares Rad (nicht gezeigt) angeordnet sein. In dem Gehäuse 14 ist ein über eine obere Öffnung 20 für den Benutzer zugänglicher Aufnahmeraum 22 ausgebildet, der mit einem Deckel 24 verschließbar ist. Am hinteren Gehäusebereich ist ein Schalter 26 vorgesehen, der zum Ein- und Ausschalten der in dem Gehäuse 14 der Basisvorrichtung 12 aufgenommenen Drucklufterzeugungseinrichtung sowie zum Regeln der von dieser Einrichtung erzeugten Druckluft dient. Zum Ein- und Ausschalten der Drucklufterzeugungseinrichtung ist der Schalter 26 als Druckschalter ausgebildet. Ein Drehen des Schalters 26 ermöglicht hingegen die Druckluftmengenregelung. Neben dem Schalter 26 sind Luftkanäle 28 vorgesehen, über welche die Drucklufterzeugungseinrichtung mit der erforderlichen Luft versorgt wird. In den Luftkanälen 28 sind jeweils nicht dargestellte Luftfilter angeordnet, welche die angesaugte Außenluft filtern. Die Luftkanäle 28 sind mit gitterartig ausgebildeten Abdeckelementen 40 abgedeckt, die mit Hilfe von Rastverbindungen (nicht dargestellt) lösbar an dem Gehäuse 14 der Basisvorrichtung 12 gehalten sind. Derartige Rastverbindungen sind dahingehend von Vorteil, dass ein Benutzer die Abdeckelemente 30 ohne Zuhilfenahme weiterer Werkzeuge problemlos von dem Gehäuse 14 entfernen und an diesem montieren kann, wenn die Luftfilter ausgetauscht werden müssen. Zur Energieversorgung der Basisvorrichtung 12 kann diese mit Hilfe eines Netzkabels mit einer Stromquelle verbunden werden. Das Netzkabel ist innerhalb des Gehäuses 14 auf eine nicht dargestellte automatische Aufwickelvorrichtung aufgewickelt und kann bei Bedarf aus dem Gehäuse 14 gezogen werden. Alternativ kann das Netzkabel aber auch lösbar mit einem an dem Gehäuse 14 angeordneten elektrischen Anschluss in Eingriff gebracht werden, so dass es in demjenigen Zustand, in dem es nicht benötigt wird, von dem Gehäuse getrennt und verstaut werden kann, bevorzugt in einem extra hierfür vorgesehenen Aufnahmeraum an der Unterseite 15 des Gehäuses (nicht gezeigt). Im vorderen Bereich des Gehäuses 14 ist ein Anschluss 34 angeordnet, an den einer der Anschlussstutzen 35 eines Druckluftschlauchs 36 lösbar angeschlossen werden kann.The Fig. 1 to 3 show various views of a spray gun system 10 according to an embodiment of the present invention. The spray gun system 10 comprises a base device 12 with a housing 14, in which a compressed air generating device, not shown, is received. At the rear part of the underside 15 of the housing 14, two rolling elements in the form of wheels 16 are received, so that the base device 12 can be moved over a substrate in the manner of a vacuum cleaner. The wheels 16 are selectively blocked by means of a brake, not shown, to prevent unwanted rolling. At the front part of the underside 15 of the housing 14 projection-like supports 18 are provided, which together with the wheels 16 form the bearing surface of the housing 14, as best in Fig. 2 can be seen. Instead of the supports 18 can also be arranged centrally on the front part of the underside 15 of the housing 14, pivotable and thus steerable wheel (not shown). In the housing 14, an accessible via an upper opening 20 for the user receiving space 22 is formed, which is closable with a cover 24. At the rear housing portion, a switch 26 is provided, which serves for switching on and off of the recorded in the housing 14 of the base device 12 compressed air generating device and for controlling the compressed air generated by this device. For switching on and off the compressed air generating device, the switch 26 is designed as a pressure switch. Turning the switch 26, however, allows the compressed air flow control. In addition to the switch 26 air channels 28 are provided, via which the compressed air generating device is supplied with the required air. In the air ducts 28, air filters, not shown, are arranged in each case, which filter the sucked outside air. The air channels 28 are covered with grid-like cover members 40, which are held by means of snap-in connections (not shown) releasably on the housing 14 of the base device 12. Such latching connections are advantageous in that a user can easily remove the cover elements 30 without the aid of further tools from the housing 14 and mount on this, when the air filter must be replaced. To supply power to the base device 12, it can be connected to a power source by means of a mains cable. The power cord is wound within the housing 14 on an unillustrated automatic winding device and can be pulled out of the housing 14 as needed. Alternatively, however, the power cord may also be detachably engaged with an electrical terminal disposed on the housing 14 so that it can be separated and stowed away from the housing in the state where it is not needed, preferably in a dedicated space Receiving space at the bottom 15 of the housing (not shown). In the front region of the housing 14, a connection 34 is arranged, to which one of the connecting pieces 35 of a compressed air hose 36 can be detachably connected.

Ferner umfasst das Spritzpistolensystem 10 eine als Handgerät ausgebildete Spritzpistole 38 mit einem Gehäuse 40, an dem einteilig ein Handgriff 42 zum Halten der Spritzpistole 38 ausgebildet ist. Im oberen Bereich des Handgriffes 42 ist ein Druckschalter 44 aufgenommen, der zum Betätigen der Spritzpistole 38 dient. Am hinteren oberen Ende des Gehäuses 40 der Spritzpistole 38 ist ein Anschluss 46 angeordnet, an den der andere der Anschlussstutzen 35 des Druckluftschlauches 36 anschließbar ist. Im vorderen Bereich des Gehäuses 40 der Spritzpistole 38 ist eine Spritzdüse 48 integriert, über die das zu sprühende Spritzgut abgegeben wird. Die Spritzdüse 48 ist vorliegend derart beschaffen, dass der Benutzer unterschiedliche Strahlformen und Strahlrichtungen einstellen kann, mit denen das Spritzgut die Spritzdüse 48 verlässt. So können beispielsweise ein punktförmiger Strahl, ein Strahl in Form einer sich horizontal erstreckenden Ellipse, ein Strahl in Form einer sich vertikal erstreckenden Ellipse oder dergleichen eingestellt werden. Am vorderen unteren Bereich des Gehäuses 40 ist ein Spritzgutaufnahmebehälter 50 lösbar gehalten, beispielsweise mit Hilfe einer Schraubverbindung oder dergleichen.Furthermore, the spray gun system 10 comprises a spray gun designed as a hand-held device 38 with a housing 40 on which a handle 42 for holding the spray gun 38 is integrally formed. In the upper region of the handle 42, a pressure switch 44 is received, which serves to actuate the spray gun 38. At the rear upper end of the housing 40 of the spray gun 38, a port 46 is arranged, to which the other of the connecting piece 35 of the compressed air hose 36 is connectable. In the front region of the housing 40 of the spray gun 38, a spray nozzle 48 is integrated, via which the sprayed material to be sprayed is discharged. The In the present case, the spray nozzle 48 is such that the user can set different jet shapes and jet directions with which the sprayed material leaves the spray nozzle 48. For example, a point beam, a beam in the form of a horizontally extending ellipse, a beam in the form of a vertically extending ellipse, or the like can be set. At the front lower portion of the housing 40, a Spritzgutaufnahmebehälter 50 is releasably held, for example by means of a screw or the like.

Um die Spritzpistole 38 mit dem daran gehaltenen Spritzgutaufnahmebehälter 50 während Spritzpausen abstellen zu können, ist in dem Deckel 24 der Basisvorrichtung 12 eine Aufnahmeeinrichtung 52 in Form von zwei Vertiefungen 54 und 56 ausgebildet. Die Vertiefung 54 ist an die Form des Spritzgutaufnahmebehälters 50 angepasst und dient zur Aufnahme derselben, und die Vertiefung 56 ist an die Form des Handgriffes 42 der Spritzpistole 38 angepasst und dient zur Aufnahme desselben. Entsprechend kann die Spritzpistole 38 zusammen mit dem Spritzgutaufnahmebehälter 50 in die Vertiefungen 54 und 56 der Aufnahmeeinrichtung 52 eingesetzt werden, wie es in Fig. 2 gezeigt ist, wodurch ein Umfallen der Komponenten und ein mit einem Umfallen einhergehendes Verschmutzen oder Beschädigen derselben sicher verhindert wird. Zudem kann die Aufnahmeeinrichtung 52 eine Befestigungseinrichtung (nicht gezeigt) aufweisen, mit deren Hilfe die Spritzpistole 38 und der Spritzgutaüfnahmebehälter 50 in der Aufnahmeeinrichtung 52 gesichert werden können. Die Befestigungseinrichtung kann dabei derart beschaffen sein, dass sie die Spritzpistole 38 und den Spritzgutaufnahmebehälter 50 mittels einer Klemmverbindung, einer Rastverbindung oder dergleichen hält.In order to be able to deposit the spray gun 38 with the spray material receiving container 50 held thereon during spray breaks, a receiving device 52 in the form of two depressions 54 and 56 is formed in the cover 24 of the base device 12. The recess 54 is adapted to the shape of the Spritzgutaufnahmebehälters 50 and serves to receive the same, and the recess 56 is adapted to the shape of the handle 42 of the spray gun 38 and serves to receive the same. Accordingly, the spray gun 38 can be used together with the Spritzgutaufnahmebehälter 50 in the recesses 54 and 56 of the receiving device 52, as in Fig. 2 is shown, whereby a falling over of the components and with a dropping fouling or damaging the same is reliably prevented. In addition, the receiving device 52 may have a fastening device (not shown) with the aid of which the spray gun 38 and the spray material acquisition container 50 can be secured in the receiving device 52. The fastening device can be such that it holds the spray gun 38 and the Spritzgutaufnahmebehälter 50 by means of a clamping connection, a snap-in connection or the like.

Wie es in Fig. 3 dargestellt ist, sind an der Unterseite des Deckels 24 Laschen 58 ausgebildet, die zur Ausbildung eines so genannten Einsteckscharniers in entsprechend ausgebildete Aussparungen 60 aufnehmbar sind, die an der Oberseite des Gehäuses 14 ausgebildet sind. Entsprechend kann der Deckel 24 wahlweise auf- und zugeklappt werden. Das Gehäuse 14, der Deckel 24 und die Scharniere sind derart aufeinander abgestimmt, dass der Deckel in einem Winkel von mehr als 90 Grad geöffnet werden kann, bevorzugt etwa 110 Grad, um einen problemlosen Zugang zum Aufnahmeraum 22 zu gewährleisten. Um den Deckel 24 fest an dem Gehäuse 14 anordnen zu können, sind im vorderen Bereich des Deckels 24 und des Gehäuses 14 jeweils Rastvorsprünge 62 und 64 ausgebildet, die miteinander in Eingriff kommen, sobald der Deckel 24 auf das Gehäuse 14 der Basisvorrichtung 12 gedrückt wird.As it is in Fig. 3 is shown, tabs 58 are formed on the underside of the lid 24, which can be accommodated to form a so-called Einsteckscharniers in correspondingly formed recesses 60, which are formed on the upper side of the housing 14. Accordingly, the lid 24 optional up and be closed. The housing 14, the lid 24 and the hinges are matched to each other so that the lid can be opened at an angle of more than 90 degrees, preferably about 110 degrees, to ensure easy access to the receiving space 22. In order to be able to arrange the cover 24 firmly on the housing 14, latching projections 62 and 64 are respectively formed in the front region of the cover 24 and the housing 14, which engage with each other as soon as the cover 24 is pressed onto the housing 14 of the base device 12 ,

Der Aufnahmeraum 22, der innerhalb des Gehäuses 14 ausgebildet ist, ist derart beschaffen, dass die Spritzpistole 38 und der Druckluftschlauch 36 zusammen mit dem Spritzgutaufnahmebehälter 50 in diesem verstaut werden können. Entsprechend kann das Spritzpistolensystem 10 bequem und ohne großen Platzbedarf gelagert werden.The receiving space 22, which is formed within the housing 14, is such that the spray gun 38 and the compressed air hose 36 together with the Spritzgutaufnahmebehälter 50 can be stored in this. Accordingly, the spray gun system 10 can be stored conveniently and without much space.

Wie es am besten in Fig. 4 gezeigt ist, ist an dem Gehäuse 14 der Basisvorrichtung 12 ein Ausziehgriff 66 ausgebildet. Der Ausziehgriff umfasst ein Gestänge 68, das in führungsartigen Aussparungen 70 des Gehäuses 14 vor- und zurück bewegbar ist und an dessen äußeren freien Enden ein Griffstück 72 montiert ist. Dabei kann das Gestänge 68 mit Hilfe nicht dargestellter Mittel in verschiedenen Ausziehpositionen arretiert werden, einschließlich in der in Fig. 4 vollständig ausgezogenen Position und in der in Fig. 2 dargestellten vollständig eingezogenen Position. Entsprechend kann ein Benutzer den Ausziehgriff 66 an dem Griffstück 72 ergreifen und in eine gewünschte Position überführen, indem er wahlweise eine vorbestimmte Druck- oder Zugkraft auf dieses ausübt, wobei die Basisvorrichtung 12 im ausgezogenen Zustand des Ausziehgriffes 66 bequem und problemlos ähnlich wie ein Koffer gehandhabt werden kann.As it is best in Fig. 4 1, an extension handle 66 is formed on the housing 14 of the base device 12. The pull-out handle comprises a linkage 68 which is movable back and forth in guide-like recesses 70 of the housing 14 and at the outer free ends of a handle 72 is mounted. In this case, the linkage 68 can be locked by means not shown in various extension positions, including in the Fig. 4 fully extended position and in the Fig. 2 illustrated fully retracted position. Accordingly, a user may grasp the pull-out handle 66 on the handle 72 and translate it to a desired position by selectively applying a predetermined compressive or tensile force thereto, the base 12 in the extended state of the pull-out handle 66 being handled conveniently and easily similar to a suitcase can be.

Um das Griffstück 72 im vollständig eingezogenen Zustand des Ausziehgriffes 66 in dem Gehäuse 14 aufzunehmen, ist an dem Gehäuse 14 eine Aussparung 74 ausgebildet. Entsprechend steht das Griffstück 72 im eingezogenen Zustand des Ausziehgriffes 66 nicht störend von dem Gehäuse 14 vor. Ferner wird in diesem Zustand das Gesamtdesign der Basisvorrichtung 12 nicht beeinträchtigt.To receive the handle 72 in the fully retracted state of the pull-out handle 66 in the housing 14, a recess 74 is formed on the housing 14. Accordingly, the handle 72 is not disturbing in the retracted state of the pull-out handle 66 from the housing 14. Furthermore, in this state, the overall design of the base device 12 is not affected.

An der Rückseite 75 des Gehäuses 14, die in Fig. 4 dem Untergrund 76 zugewandt ist, ist eine Ausnehmung 78 ausgebildet, in der eine Stützeinrichtung 80 um einen Schwenkzapfen 82 schwenkbar aufgenommen ist. Diese Stützeinrichtung 80 kann entsprechend zwischen einer zurückgezogenen Position, in der sie in der Ausnehmung 78 aufgenommen ist, wie es in Fig. 2 dargestellt ist, und einer Stützposition bewegt werden, in der sie eine Standfläche 84 für das Gehäuse 14 bildet, wie es in Fig. 4 gezeigt ist. Somit kann das Gehäuse 14 der Basisvorrichtung 12 bequem in dem in Fig. 4 gezeigten Zustand abgestellt werden.At the back 75 of the housing 14, which in Fig. 4 the base 76 faces, a recess 78 is formed in which a support means 80 is pivotally received about a pivot pin 82. This support means 80 may accordingly between a retracted position in which it is received in the recess 78, as shown in FIG Fig. 2 is shown, and a support position to be moved, in which it forms a footing 84 for the housing 14, as shown in FIG Fig. 4 is shown. Thus, the housing 14 of the base device 12 can be conveniently located in the in Fig. 4 be turned off state shown.

Um die Stützeinrichtung 80 aus der in Fig. 4 dargestellten Position selbsttätig in ihre zurückgezogene Position zu überführen, umfasst diese ein Federelement (nicht gezeigt), das die Stützeinrichtung 80 in die zurückgezogene Position vorspannt. Auf diese Weise soll insbesondere verhindert werden, dass die Stützeinrichtung 80 im horizontal angeordneten Zustand des Gehäuses 14 von dem Gehäuse 14 derart vorsteht, dass eine Person mit ihrem Bein gegen diese stoßen und sich verletzen kann.To the support means 80 from the in Fig. 4 shown position to automatically transfer to its retracted position, this includes a spring element (not shown), which biases the support means 80 in the retracted position. In this way, it is intended, in particular, to prevent the support device 80 from projecting from the housing 14 in the horizontally arranged state of the housing 14 in such a way that a person can push his leg against it and injure himself.

Fig. 5 ist eine perspektivische Teilunteransicht der in Fig. 4 dargstellten Basisvorrichtung 12, die einen Zustand zeigt, in dem sich der Ausziehgriff 66 in seinem eingezogenen Zustand befindet. Wie es anhand dieser Darstellung gut zu erkennen ist, steht das Griffstück 72 in diesem Zustand nicht von dem Gehäuse 14 vor und ist für einen Benutzer dennoch gut zugänglich. Fig. 5 is a partial perspective view of the in Fig. 4 illustrated base device 12, which shows a state in which the pull-out handle 66 is in its retracted state. As can be seen clearly from this illustration, the handle 72 is not in this state before of the housing 14 and is still easily accessible to a user.

An der Unterseite 15 des Gehäuses 14 der Basisvorrichtung 12 ist zwischen den Stützen 18 eine Griffmulde 86 angeordnet, an der das Gehäuse mit der Hand 88 eines Benutzers erfasst und hochgehoben werden kann, um die Basisvorrichtung 12 zu tragen. Diese Positionierung der Griffmulde 86 ist optimal in Bezug auf den Schwerpunkt der Basisvorrichtung 12 gewählt, so dass das Tragen der Basisvorrichtung 12 erleichtert wird.On the underside 15 of the housing 14 of the base device 12, a recessed grip 86 is arranged between the supports 18, on which the housing can be grasped with the hand 88 of a user and lifted to carry the base device 12. This positioning of the recessed grip 86 is optimal with respect to the center of gravity the base device 12 is selected, so that the carrying of the base device 12 is facilitated.

Es sollte klar sein, dass die zuvor beschriebene Ausführungsform des erfindungsgemäßen Spritzpistolensystems nur als Beispiel dient und in keinerlei Hinsicht einschränkend ist. Vielmehr sind Modifikationen und Änderungen möglich, ohne den Schutzbereich der vorliegenden Erfindung zu verlassen, der durch die beiliegenden Ansprüche definiert ist.It should be understood that the above-described embodiment of the spray gun system according to the invention is given by way of example only and is in no way limiting.
