Definitions

  • the present invention relates to a mobile compressed air device unit according to the preamble of claim 1.
  • a generic mobile compressed air device unit is from the US 6,932,128 B2 known, which relates to a compressed air-operated working device which is connected via a flexible hose connection to a compressed air storage unit provided with a carrying strap.
  • 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.
  • the storage unit is carried on the body of the operator handling the implement.
  • the radius of action or handling radius of the implement is limited by the length of the hose connection.
  • the US 2005/252944 A1 discloses a mobile compressed air device unit with a magazine device arranged below a compressed air storage unit.
  • the US 2013/1755313 A1 as well as the JP 2002 059374 A each describe a mobile compressed air device unit with a magazine device arranged on the side of a compressed air storage unit.
  • 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 mobile compressed air device unit according to the invention has the features of claim 1.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the carrier device designed as a compressed air connection has a design as a handle.
  • 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.
  • connection axes are arranged perpendicular to the connection side.
  • 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.
  • 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.
  • 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.
  • a compressed air reducing device and a safety valve are preferably arranged in the middle part of the housing.
  • a mobile compressed air device unit 10 comprising a compressed air-operated working device 11, a compressed air storage unit 12 and a compressed air connection 13 designed as a compressed air reducing unit 30, is shown in different configurations.
  • the compressed air connection 13 has a compressed air housing 14, which is provided on a connection side 15 with a compressed air device connection 16 designed here as a quick coupling and a compressed air storage connection 17 for connection to the compressed air storage unit 12 designed here as a cartridge.
  • the working device 11 and the compressed air storage unit 12 are provided with suitable mating connections 18 and 19, respectively, which, in the case of the mating connection 18, enable a locking receptacle in the compressed air device connection 16 and, in the case of the mating connection 19, a screw connection to the compressed air storage connection 17.
  • 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.
  • 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.
  • connection axis 25 of the compressed air device connection 16 and a connection axis 28 of the compressed air storage connection 17 are arranged parallel to one another and have an axis distance a, which corresponds essentially to the distance b of a longitudinal axis 29 of the handle part 20 from a longitudinal axis 31 of the magazine device 23, such as that in the in Fig. 1
  • the position of the compressed air storage unit 12 shown on the left-hand side is located not only in an arrangement parallel to the magazine device 23, but also in an arrangement that overlaps the magazine device 23, i.e. neither the working device 11 protrudes beyond the magazine device 23 downward, nor an engagement of one of the Handgrip part 20 grasping hand of an operator into a passage space D formed between the handle part 20 and the magazine device 23.
  • the compressed air connection 13 forms a detachable mechanical connection console between the work device 11 and the compressed air storage unit 12, the connection console enabling the formation of a handling unit comprising the work device 11 and the compressed air storage unit 12, in particular when the compressed air device unit 10 designed as a handling unit is handed over by an operator to another operator, the compressed air device unit 10 can be taken over by the other operator by grasping the connection console.
  • the compressed air connection 13 is not only designed as a connection bracket, but also simultaneously forms a compressed air reducing unit 30 in the compressed air housing 14, which has a compressed air reducing device 32 in addition to the compressed air working device connection 16 and the compressed air storage connection 17.
  • the compressed air reducing device 32 is located in a housing middle part 33, whereas the compressed air device connection 16 and the compressed air storage connection 17 are each arranged at the free end of a housing leg 34 and housing leg 35, respectively, which extend in opposite directions away from the housing middle part 33 and are arranged in a common housing plane .
  • the compressed air storage connection 17 which is used for connection with the in the Figs. 1 to 4
  • the compressed air storage unit 12 shown here designed as a cartridge, is connected via a storage air line 37 to a compressed air inlet 38 of the compressed air reducing device 32 and the compressed air device connection 16 is connected via a working air line 39 to a compressed air outlet 40 of the compressed air reducing device 32.
  • 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.
  • a closing spring 41 arranged in the compressed air reducing device 32 and an adjusting spring 42 deviating pressure differences can be set if necessary.
  • the storage air line 37 is provided with a manometer 43 for displaying the filling pressure of the compressed air storage unit 12.
  • a safety valve 44 is provided in the working air line 39 parallel to the compressed air device connection 16, which valve prevents the working device 11 from being overloaded with compressed air in the event of a failure of the compressed air reducing device 32.
