- the present invention is therefore based on the object of proposing a mobile compressed air device unit which enables the compressed air device unit to be easily handled by several operators.

- the working device 11 in the present case is designed, for example, as a compressed air nailer which has a drive piston unit 21 at one axial end of a handle part 20 with an attachment mouthpiece 22, which serves to dispense stored fastening means, such as nails, in a magazine device 23, which extends parallel to the handle part 20, which when a triggering device 24 arranged on the handle part 20 is actuated from an expulsion channel of the attachment mouthpiece 22 and in a surface which is in contact with the attachment mouthpiece 22 can be driven in.

- the flexibility of the compressed air device unit is to be emphasized, so that a combination of the compressed air storage unit with a working device designed as a compressed air grinder or a compressed air drill is possible to form the compressed air device unit defined by claim 1 and shown here only in one embodiment.
- the arrangement of the compressed air storage unit 12 relative to the working device 11 can be changed by pivoting the compressed air connection 13 together with the compressed air storage unit 12 connected to it about a connection axis 25 of the compressed air device connection 16 and thus approximately from the in Fig. 1 right-hand position shown, in which the compressed air storage unit 12 is essentially parallel to a right longitudinal side 26 of the magazine device 23, can be pivoted into a left-hand position in which the compressed air storage unit 12 is essentially parallel to a left longitudinal side 27 of the magazine device 23.

- the compressed air reducing device 32 is set to a defined pressure difference such that, for example, a storage air with 300 bar at the compressed air inlet 38 is reduced to a working air pressure of 6.5 bar at the compressed air outlet 40.

Description
Die vorliegende Erfindung betrifft eine mobile Druckluftgeräteeinheit nach dem Oberbegriff des Anspruchs 1.The present invention relates to a mobile compressed air device unit according to the preamble of claim 1.
Eine gattungsgemäße mobile Druckluftgeräteeinheit ist aus der
Die bekannte mobile Druckluftgeräteeinheit bietet zwar den Vorteil, dass das druckluftbetriebene Arbeitsgerät unabhängig von einem Netzanschluss über die angeschlossene Druckluftspeichereinheit betrieben werden kann. Jedoch ist es für den Einsatz des Arbeitsgerätes erforderlich, dass die Speichereinheit am Körper der das Arbeitsgerät handhabende Bedienperson getragen wird.The known mobile compressed air device unit offers the advantage that the compressed air operated work device can be operated independently of a mains connection via the connected compressed air storage unit. However, for the use of the implement it is necessary that the storage unit is carried on the body of the operator handling the implement.
Weiterhin ist bezogen auf den Standort der Bedienungsperson der Aktionsradius oder Handhabungsradius des Arbeitsgerätes durch die Länge der Schlauchverbindung begrenzt. Hierdurch ist es beispielsweise nicht möglich, das Arbeitsgerät von einer Bedienperson an eine weitere Bedienperson zu übergeben, ohne dass eine entsprechende Übergabe der über den Tragegurt an der ersten Bedienperson fixierten Druckluftspeichereinheit erfolgt. Damit ist in der Praxis die Handhabung des Arbeitsgerätes durch eine Mehrzahl von Bedienpersonen kaum möglich.Furthermore, based on the location of the operator, the radius of action or handling radius of the implement is limited by the length of the hose connection. As a result, it is not possible, for example, to transfer the work device from one operator to another operator to be transferred without a corresponding transfer of the compressed air storage unit fixed to the first operator via the carrying strap. This means that in practice it is hardly possible for a plurality of operators to handle the implement.
Die
Die
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine mobile Druckluftgeräteeinheit vorzuschlagen, die eine einfache Handhabung der Druckluftgeräteeinheit von mehreren Bedienpersonen ermöglicht.The present invention is therefore based on the object of proposing a mobile compressed air device unit which enables the compressed air device unit to be easily handled by several operators.
Zur Lösung dieser Aufgabe weist die erfindungsgemäße mobile Druckluftgeräteeinheit die Merkmale des Anspruchs 1 auf.To achieve this object, the mobile compressed air device unit according to the invention has the features of claim 1.
Bei der erfindungsgemäßen mobilen Druckluftgeräteeinheit ist die Druckluftverbindung als Trägereinrichtung zur schlauchlosen Verbindung des Arbeitsgerätes mit der Druckluftspeichereinheit in einer definierten Relativanordnung und Ausbildung der Druckluftgeräteeinheit als Handhabungseinheit ausgebildet.In the mobile compressed air device unit according to the invention, the compressed air connection is designed as a carrier device for the hose-free connection of the working device to the compressed air storage unit in a defined relative arrangement and the compressed air device unit is designed as a handling unit.
Abweichend von der bekannten mobilen Druckluftgeräteeinheit ist kein an der Bedienperson angeordneter Tragegurt erforderlich, um die Handhabung eines durch eine Schlauchverbindung mit der Druckluftspeichereinheit verbundenen Arbeitsgerätes zu ermöglichen. Vielmehr dient die Druckluftverbindung selbst als Trägereinrichtung zur mechanischen Verbindung des Arbeitsgerätes mit der Druckluftspeichereinheit. Somit ermöglicht die als Trägereinrichtung ausgebildete Druckluftverbindung eine schlauchlose Verbindung zwischen der Druckluftspeichereinheit und dem Arbeitsgerät, wobei die Trägereinrichtung gleichzeitig eine Handhabung des Arbeitsgerätes zusammen mit der daran angeschlossenen Druckluftspeichereinheit als Handhabungseinheit ermöglicht.In contrast to the known mobile compressed air device unit, a carrying strap arranged on the operator is not required in order to enable the handling of a working device connected to the compressed air storage unit by a hose connection. Rather, the compressed air connection itself serves as a carrier device for the mechanical connection of the working device to the compressed air storage unit. The compressed air connection designed as a carrier device thus enables a hose-free connection between the compressed air storage unit and the working device, the carrier device simultaneously enabling the working device to be handled together with the compressed air storage unit connected to it as a handling unit.
Im Unterschied zu der bekannten mobilen Druckluftgeräteeinheit kann somit ohne Weiteres eine Nutzung der erfindungsgemäßen mobilen Druckluftgeräteeinheit durch mehrere Bedienpersonen durch einfache Übergabe der Handhabungseinheit von einer Bedienperson an die nächste Bedienperson erfolgen, ohne dass hierzu besondere Maßnahmen erforderlich wären.In contrast to the known mobile compressed air device unit, the mobile compressed air device unit according to the invention can easily be used by several operators by simply handing over the handling unit from one operator to the next, without special measures being required.
Durch die Ausbildung der Druckluftverbindung als Trägereinrichtung kann dabei die Übergabe beispielsweise derart erfolgen, dass das Arbeitsgerät noch von der ersten Person gehalten wird, während die nächste Bedienperson zur Übernahme die Trägereinrichtung mit der einen Hand erfasst, um zur Bedienung des Arbeitsgerätes die Handhabungseinheit an die andere Hand zu übergeben und hierzu den Handgriff des Arbeitsgerätes umgreift.By designing the compressed air connection as a carrier device, the handover can take place, for example, in such a way that the work device is still held by the first person while the next operator grabs the carrier device with one hand to operate the work device in order to operate the work device Hand to hand and for this purpose grasps the handle of the implement.
Hierzu kann es sich als besonders vorteilhaft erweisen, wenn die als Druckluftverbindung ausgebildete Trägereinrichtung eine Ausgestaltung als Handgriff aufweist.For this purpose, it can prove to be particularly advantageous if the carrier device designed as a compressed air connection has a design as a handle.
Erfindungsgemäß ist die Druckluftverbindung als Druckluftmindereinheit mit einem Druckluftspeicheranschluss und einem Druckluftgeräteanschluss ausgebildet, die auf einer Anschlussseite eines Gehäuses der Druckluftmindereinheit angeordnet sind. Somit ist es möglich, dass bei der Handhabungseinheit der Druckluftspeicher und das Arbeitsgerät sich von einer gemeinsamen Gehäuseseite weg erstrecken, sodass eine kompakte Ausbildung der Handhabungseinheit möglich wird.According to the invention, the compressed air connection is designed as a compressed air reducer unit with a compressed air storage connection and a compressed air device connection, which are arranged on a connection side of a housing of the compressed air reducer unit. It is thus possible for the compressed air reservoir and the working device in the handling unit to extend away from a common housing side, so that a compact design of the handling unit is possible.
Dadurch, dass der Druckluftspeicheranschluss und der Druckluftgeräteanschluss erfindungsgemäß parallele Anschlussachsen aufweisen, wird eine besonders kompakte Ausgestaltung der Handhabungseinheit möglich.Because the compressed air storage connection and the compressed air device connection have parallel connection axes according to the invention a particularly compact design of the handling unit is possible.
Erfindungsgemäß sind dabei die Anschlussachsen senkrecht zur Anschlussseite angeordnet.According to the invention, the connection axes are arranged perpendicular to the connection side.
Erfindergemäß weisen weiterhin die Anschlussachsen einen Achsenabstand voneinander aufweisen, der dem Achsenabstand einer Längsachse eines sich koaxial zum Druckluftgeräteanschluss erstreckenden Handgriffteils des angeschlossenen Arbeitsgerätes zu einer Längsachse einer sich im Wesentlichen parallel zum Handgriffteil erstreckenden Magazineinrichtung des Arbeitsgerätes entspricht, kann eine zu einer Magazineinrichtung im Wesentlichen parallele Anordnung der Druckluftspeichereinheit am Arbeitsgerät erfolgen.According to the invention, the connection axes furthermore have an axial spacing from one another which corresponds to the axial spacing of a longitudinal axis of a handle part of the connected tool that extends coaxially to the compressed air device connection to a longitudinal axis of a magazine device of the tool that extends essentially parallel to the handle part, an arrangement that is essentially parallel to a magazine device the compressed air storage unit on the work device.
Vorzugsweise ist der Druckluftgeräteanschluss der Druckluftverbindung derart ausgebildet, dass zwischen dem Arbeitsgerät und der mittels des Druckluftgeräteanschlusses mit dem Arbeitsgerät verbundenen Druckluftverbindung eine Relativdrehung um die Anschlussachse des Druckluftgeräteanschlusses möglich ist, sodass etwa ein Umschwenken der Druckluftspeichereinheit aus einer zu einer linken Längsseite der Magazineinrichtung parallelen Anordnung in eine zu einer rechten Längsseite der Magazineinrichtung parallelen Anordnung möglich ist. Dies erweist sich insbesondere bei der Handhabung beziehungsweise dem Einsatz des Arbeitsgerätes in Raumecken als vorteilhaft, wo das Arbeitsgerät in einer zu einer Raumwand möglichst benachbarten Anordnung eingesetzt werden soll, ohne dass die Druckluftspeichereinheit zwischen der Raumwand und dem Arbeitsgerät angeordnet ist.The compressed air device connection of the compressed air connection is preferably designed in such a way that a relative rotation about the connection axis of the compressed air device connection is possible between the work device and the compressed air connection connected to the work device by means of the compressed air device connection, so that, for example, the compressed air storage unit can be pivoted from an arrangement parallel to a left longitudinal side of the magazine device in an arrangement parallel to a right long side of the magazine device is possible. This proves to be particularly advantageous when handling or using the tool in corners of a room, where the tool is to be used in an arrangement as close as possible to a room wall without the compressed air storage unit being arranged between the room wall and the tool.
Die Druckluftmindereinheit ist zur Ausbildung einer Druckluftverbindung zwischen einem mit Druckluft betriebenen Arbeitsgerät und einer Druckluftspeichereinheit als Verbindungskonsole zur mechanischen Verbindung des Arbeitsgerätes mit der Druckluftspeichereinheit und Ausbildung einer das Arbeitsgerät und die Druckluftspeichereinheit umfassenden, eine Handhabungseinheit bildenden Druckluftgeräteeinheit nach Anspruch 1 ausgeführt. Vorzugsweise weist die Druckluftmindereinheit ein Gehäuse auf mit zwei in einer gemeinsamen Gehäuseebene zueinander versetzt angeordneten und in einem Gehäusemittelteil miteinander verbundenen Gehäuseschenkeln, die auf einer Anschlussseite des Gehäuses jeweils an ihrem freien Ende ein Druckluftgeräteanschluss und einen Druckluftspeicheranschluss mit zueinander parallele Anschlussachsen aufweisen, derart, dass in dem einen Gehäuseschenkel der Druckluftspeicheranschluss und in dem anderen Gehäuseschenkel der Druckluftgeräteanschluss angeordnet ist. Hierdurch wird eine besonders kompakte Ausgestaltung des Gehäuses mit einem möglichst kleinen Gehäusevolumen möglich, bei der die größte Längserstreckung des Gehäuses im Wesentlichen durch den Achsabstand der Anschlussachsen gegeben ist.The compressed air reduction unit is to form a compressed air connection between a work device operated with compressed air and a compressed air storage unit as a connection console for the mechanical connection of the Work device with the compressed air storage unit and the formation of a compressed air device unit comprising the work device and the compressed air storage unit and forming a handling unit according to claim 1. The compressed air reducer unit preferably has a housing with two housing legs which are offset from one another in a common housing plane and are connected to one another in a central housing part, each having a compressed air device connection and a compressed air storage connection with parallel connection axes on a connection side of the housing at their free end, such that in the compressed air storage connection is arranged in one housing leg and the compressed air device connection is arranged in the other housing leg. This enables a particularly compact design of the housing with the smallest possible housing volume, in which the greatest longitudinal extent of the housing is essentially given by the center distance of the connection axes.
Weiterhin sind vorzugsweise in dem Gehäusemittelteil eine Druckluftmindereinrichtung und ein Sicherheitsventil angeordnet.Furthermore, a compressed air reducing device and a safety valve are preferably arranged in the middle part of the housing.
Nachfolgend werden weitere Ausführungsformen der Erfindung anhand der Zeichnungen näher erläutert.Further embodiments of the invention are explained in more detail below with reference to the drawings.
