Abstract

The handgrip (1) is assembled from wo half-shells (3) held together and secured to the hose (2) by a bayonet closure ring (5). The half-shells form a surround (6) for a one-piece tubular air duct (7) and a handle (8) with a hole (9) for the operator's fingers. A rotary electrical coupling is formed by sliding contacts (12) in one half-shell co-operating with slip-rings (10) on a bushing (11). Electric conductor links (17) and manually operated switches (14) are mounted at the transition between the handle and a projecting coupling section (15) of the air duct.

Description

Die Erfindung betrifft einen Staubsaugerschlauch gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a vacuum cleaner hose according to the preamble of the first claim.

Es ist ein Staubsaugerschlauch bekannt, an dessen Saugschlauch ein aus Kunststoff gefertigtes Griffstück angesetzt ist, an das andererseits ein insbesondere metallisches Saugrohr angesteckt werden kann. Das Griffstück enthält ein durchgehendes Luftführungskanalstück und ist mit einem von Hand zu umfassenden Griffteil versehen. Von Nachteil ist hierbei, daß die notwendige Dichtheit des Luftführungskanalstücks die ergonomische Gestaltung des Griffstücks beeinträchtigt.A vacuum cleaner hose is known, on the suction hose of which a plastic handle is attached, to which, on the other hand, a particularly metallic suction pipe can be attached. The handle contains a continuous air duct channel piece and is provided with a handle part to be encompassed by hand. The disadvantage here is that the necessary tightness of the air duct piece affects the ergonomic design of the handle.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Staubsaugerschlauch gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch welche ein einfacher, kostengünstiger Aufbau erreicht wird.The invention has for its object to take a vacuum cleaner hose according to the preamble of the first claim measures by which a simple, inexpensive structure is achieved.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Bei einer Ausgestaltung eines Staubsaugerschlauchs gemäß der Erfindung wird in ein aus zwei Halbschalen ausgebildetes Griffstück ein für sich hergestelltes einstückiges Luftkanalrohr eingefügt, das einendig mit dem Saugschlauch verbunden werden kann und dessen anderes Ende als Steckkupplungsteil aus den Halbschalen nach außen ragt und für das Aufstecken eines Verlängerungsrohrs oder des Anschlußstutzens eines Saugwerkzeugs ausgebildet ist. Die Halbschalen können daher frei nach ergonomischen Gesichtspunkten gestaltet und für die Aufnahme von elektrischen Bauteilen, wie Schalteinrichtungen, elektrische Steckkupplungen oder drehbare Schleifringkupplungen geformt werden. Eine Abdichtung der Trennfugen der Halbschalen entfällt dabei durch die Anwendung des gesonderten Luftkanalrohrs, das dabei mehrfach abgewinkelt sein kann und dessen Oberflächengestaltung zumindest innerhalb der Halbschalen fertigungstechnischen Gegebenheiten entsprechend ausgebildet sein kann. Der Saugschlauch kann innerhalb der Halbschalen unmittelbar auf das eine Ende des Luftkanalrohrs dicht aufgesetzt werden. Es ist jedoch möglich, den Schlauch an einer mit Schleifringen versehenen Buchse einer elektrischen Drehkupplung festzusetzen, wobei die Buchse drehbar an bzw. auf dem zugehörigen Ende des Luftkanalrohrs innerhalb der Halbschalen gelagert werden kann, wobei die zugehörigen feststehenden Schleifkontakte zumindest in einer Halbschale ortsfest gehalten sind. Vorzugsweise ist das Griffstück mit einem vom Luftführungskanalstück abgesetzten besonderen Griffbügel versehen, in dem elektrische Leitungen von der Drehkupplung zu einem insbesondere dem Griffbügel zugeordneten und manuell bedienbaren Schaltelement führen, das mit einer Steckbuchse elektrisch verbunden ist, die am Übergang von den Griffhalbschalen und dem daraus herausragenden Kupplungsabschnitt des Luftkanalrohrs angeordnet ist. Die Steckbuchse ist dabei insbesondere an Halterungen festgesetzt, die einerseits an den Halbschalen und andererseits am Luftkanalrohr vorgesehen sind. Ein besonderer Vorteil ergibt sich dadurch, daß der Griffteil und insbesondere der Griffbügel mit einem offenliegenden elektrischen Leiter versehen werden kann, der vorzugsweise in eine Trennfuge der Halbschalen eingelegt ist und beim Umfassen des Griffteils manuell berührt wird. Dieser elektrische Leiter, der vorzugsweise als relativ steifer Draht ausgebildet ist, erstreckt sich vom Griffteil bis zu dem aus den Halbschalen nach außen ragenden Kupplungsabschnitt des Luftkanalrohres und liegt dort ebenfalls frei zugänglich an der Mantelfläche und bildet einen offenen elektrischen Kontakt, der beim Aufschieben eines Metallrohres mit demselben in elektrisch leitende Verbindung tritt. Während des Saugbetriebes am metallischen oder metallisierten Saugrohr auftretende elektrostatische Spannungen werden dadurch über diesen elektrischen Leiter abgeleitet. Bei einem Zugriff zum Saugrohr erhält dann die Bedienungsperson keinen elektrischen Schlag.In one embodiment of a vacuum cleaner hose according to the invention, a self-made one-piece air duct tube is inserted into a handle formed from two half-shells, which can be connected at one end to the suction hose and the other end of which protrudes outwards from the half-shells as a plug-in coupling part and for attaching an extension tube or the Connection piece of a suction tool is formed. The half-shells can therefore be designed freely from an ergonomic point of view and shaped to accommodate electrical components such as switching devices, electrical plug-in couplings or rotating slip ring couplings. Sealing of the parting lines of the half-shells is not necessary due to the use of the separate air duct tube, which can be angled several times and the surface design of which, at least within the half-shells, can be designed accordingly in terms of manufacturing technology. The suction hose can be placed tightly on one end of the air duct pipe within the half-shells. However, it is possible to attach the hose to a bushing of an electrical rotary coupling provided with slip rings, the bushing being able to be rotatably mounted on or on the associated end of the air duct tube within the half-shells, the associated fixed sliding contacts being held stationary in at least one half-shell . Preferably, the handle piece is provided with a special handle bracket, offset from the air duct channel piece, in which electrical lines lead from the rotary coupling to a switching element, which is associated with the handle bracket and which can be operated manually, and which is electrically connected to a plug socket which is located at the transition from the handle half-shells and the protruding therefrom Coupling section of the air duct pipe is arranged. The socket is particularly attached to brackets, which are provided on the one hand on the half-shells and on the other hand on the air duct pipe. A particular advantage results from the fact that the handle part and in particular the handle bar can be provided with an exposed electrical conductor, which preferably is inserted in a parting line of the half-shells and is touched manually when gripping the grip part. This electrical conductor, which is preferably designed as a relatively stiff wire, extends from the handle part to the coupling section of the air duct tube projecting outward from the half-shells and is also freely accessible on the lateral surface and forms an open electrical contact that occurs when a metal tube is pushed on with it in electrically conductive connection. Electrostatic voltages occurring on the metallic or metallized suction pipe during suction operation are thereby dissipated via this electrical conductor. When the suction pipe is accessed, the operator receives no electric shock.

Die Erfindung ist nachfolgend anhand der Skizzen eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with the aid of the sketches of an exemplary embodiment.

Es zeigen:

  • Fig. 1 einen Staubsaugerschlauch im Bereich eines Griffstücks und daran angesetztem Saugschlauch sowie integrierter elektrischer Drehkupplung,
  • Fig. 2 eine Anordnung mit unmittelbar an ein Luftkanalrohr angeschlossenem Saugschlauch und
  • Fig. 3 eine Teilansicht des Griffstücks im Bereich eines freien Kupplungsabschnitts.
Show it:
  • 1 is a vacuum cleaner hose in the area of a handle and attached suction hose and integrated electrical rotary coupling,
  • Fig. 2 shows an arrangement with a suction hose connected directly to an air duct and
  • Fig. 3 is a partial view of the handle in the region of a free coupling section.

Ein Staubsaugerschlauch weist ein manuell zu handhabendes Griffstück 1 auf, das einendig mit einem Saugschlauch 2 verbunden ist. Das Griffstück 1 besteht aus zwei in Längsrichtung geteilten Halbschalen 3, von welchen in den Figuren lediglich eine dargestellt ist, um den Innenaufbau zu zeigen. Die zweite spiegelbildlich ausgebildete Halbschale wird als Abschluß auf die Anordnung gemäß den Figuren aufgesetzt und im Bereich von Schraubverbindungsmitteln 4 sowie einem am Übergang zum Saugschlauch vorgesehenen Bajonettverschlußring 5 zusammengehalten. Die Halbschalen 3 bilden ein durchgehendes Luftkanalstück 6, welches ein eingefügtes einstückiges Luftkanalrohr 7 umschließt. Zugleich sind die Halbschalen 3 im mittleren Bereich mit einem als Griffbügel 8 ausgebildeten Griffteil versehen, der brückenförmig den mittleren Abschnitt des Luftführungskanalstücks überspannt, so daß eine Durchgrifföffnung 9 gebildet ist. Das Luftkanalrohr 7 ist ein eigenständiges Bauteil und wird klemmschlüssig zwischen den Halbschalen 3 gehalten. Es kann daher bei freier Oberflächengestaltung mehrmals leicht geknickt sein und weist in Längsrichtung keine Trennfuge auf, die Undichtigkeiten mit sich bringen könnte oder besondere Abdichtmaßnahmen erforderte. Das mehrfache, vorliegend dreifache Knicken des Luftkanalrohrs 7 ermöglicht eine Anpassung an die notwendige ergonomische Gestaltung des gesamten Griffstücks. Insbesondere sind Abdichtungsmaßnahmen im Trennfugenbereich zwischen den Halbschalen damit überflüssig. Dabei ermöglicht es dieser Aufbau in besonders einfacher Weise, den Saugschlauch 2 drehbeweglich am Luftkanalrohr 7 zu lagern und dabei insbesondere eine elektrische Drehkupplung vorzusehen, deren mit Schleifringen 10 versehene Buchse 11 einerseits luftdicht mit dem Saugschlauch 2 verbunden ist und die andererseits drehbeweglich und gegen Axialverschiebung gesichert auf dem zugehörigen Ende des Luftkanalrohres 7 innerhalb des von den Halbschalen 3 umschlossenen Raumes gegen manuellen Zugriff geschützt angeordnet ist. Die Halbschalen 3 und das Luftkanalrohr 7 bestehen aus elektrisch isolierendem Werkstoff. Den Schleifringen zugeordnet sind feststehende Schleifkontakte 12, die auf einem gemeinsamen Träger 13 zumindest in einer Halbschale 3 festgesetzt sind. Außerdem ist ein problemloser Einbau von elektrischen Leitungsverbindungen 17 und weiteren, manuell zu bedienden Schalteinrichtungen 14 möglich, die am Übergang des Griffbügels 8 zum frei nach außen ragenden Kupplungsabschnitt 15 des Luftkanalrohrs 7 in angepaßten Aussparungen zwischen den Halbschalen 3 gehaltert werden können. Im Bereich des Kupplungsabschnitts 15 kann zwischen die Wandung der Halbschalen 3 und des Kupplungsabschnittes 15 auch eine elektrische Steckbuchse 16 mit axial parallel zum Kupplungsabschnitt 15 gericheteten Steckkontakten eingesetzt werden, wobei die Steckbuchse 16, die Schalteinrichtung 14 und die Schleifringanordnung 10, 12 mittels elektrischer Leitungen 17 verbunden sind, die durch den hohlen Griffbügel 8 und einen entsprechenden Hohlraum zwischen der Schalteinrichtung 14 und der Steckbuchse 16 verlaufen.A vacuum cleaner hose has a manually operated handle 1 which is connected at one end to a suction hose 2. The handle 1 consists of two longitudinally divided half-shells 3, of which in the Figures only one is shown to show the internal structure. The second mirror-shaped half-shell is placed as a conclusion on the arrangement according to the figures and held together in the area of screw connection means 4 and a bayonet lock ring 5 provided at the transition to the suction hose. The half-shells 3 form a continuous air duct piece 6, which encloses an inserted one-piece air duct tube 7. At the same time, the half-shells 3 are provided in the central region with a grip part designed as a handle bracket 8, which spans the central section of the air duct piece in a bridge-like manner, so that a passage opening 9 is formed. The air duct pipe 7 is an independent component and is held between the half-shells 3 with a clamp. It can therefore be slightly bent several times with a free surface design and does not have a separating joint in the longitudinal direction, which could result in leaks or require special sealing measures. The multiple, in this case triple kinking of the air duct tube 7 enables adaptation to the necessary ergonomic design of the entire handle. In particular, sealing measures in the joint area between the half-shells are therefore superfluous. This construction makes it possible in a particularly simple manner to mount the suction hose 2 rotatably on the air duct pipe 7 and, in particular, to provide an electrical rotary coupling, the bushing 11 provided with slip rings 10 of which is connected on the one hand in an airtight manner to the suction hose 2 and which on the other hand is rotatable and secured against axial displacement is arranged on the associated end of the air duct 7 within the space enclosed by the half-shells 3 to protect it against manual access. The half-shells 3 and the air duct pipe 7 consist of electrically insulating material. Fixed slip contacts 12 are assigned to the slip rings and are fixed on a common carrier 13 at least in a half-shell 3. In addition, a trouble-free installation of electrical line connections 17 and further, manually operated switching devices 14 is possible, which can be held in adapted recesses between the half-shells 3 at the transition of the handle 8 to the freely projecting coupling section 15 of the air duct pipe 7. In the area of the coupling section 15, an electrical socket 16 with plug contacts oriented axially parallel to the coupling section 15 can also be inserted between the wall of the half-shells 3 and the coupling section 15, the socket 16, the switching device 14 and the slip ring arrangement 10, 12 by means of electrical lines 17 are connected, which run through the hollow handle 8 and a corresponding cavity between the switching device 14 and the socket 16.

In besonders vorteilhafter Ausgestaltung wird bei dem Aufbau aus zwei Halbschalen 3 die Möglichkeit geschaffen, eine elektrische Leitungsverbindung zwischen dem Griffbügel 8 und dem Kupplungsanschluß 15 auszubilden. Hierzu ist in die dem Luftführungskanalstück 6 zugewandte Trennfuge im Bereich des Griffbügels 8 ein elektrischer Leiter 18, insbesondere ein der Kontur des Griffbügels 8 folgender relativ steifer Metalldraht eingelegt, der ggf. in einer angepaßten Mantellängsnut des Luftkanalrohrs 7 bis in den Kupplungsabschnitt 15 geführt ist und dort frei an der Mantelfläche zugänglich ist, so daß beim Aufstecken eines Metallrohres ein elektrischer Kontakt 19 durch entsprechende Formgebung des Metalldrahtes 18 in radialer Richtung federnd in elektrisch leitende Verbindung mit dem Metallrohr tritt. Am Metallrohr während des Saugbetriebs auftretende elektrostatische Aufladungen werden somit unmittelbar der Bedienungsperson durch deren Eingriff mit dem elektrischen Leiter 18 vermittelt, so daß bereits während des Betriebs über die Bedienungsperson elektrostatische Ladungen abgeleitet werden oder zumindest kein Spannungspotentialunterschied gegeben ist, wenn bei erfaßtem Griffbügel 8 mit der anderen Hand das metallische Saugrohr berührt wird. Die Steckbuchse 16 ist im übrigen einerseits an einer am Kupplungsabschnitt 15 vorgesehenen Halterung 20 und andererseits innerhalb der Halbschalen 3 festgesetzt.In a particularly advantageous embodiment, the construction of two half-shells 3 creates the possibility of forming an electrical line connection between the handle bar 8 and the coupling connection 15. For this purpose, an electrical conductor 18, in particular a relatively stiff metal wire following the contour of the handle bar 8, is inserted into the joint facing the air guide channel piece 6 in the area of the handle bar 8, which is possibly guided in an adapted jacket longitudinal groove of the air channel tube 7 into the coupling section 15 and is freely accessible there on the lateral surface, so that when a metal tube is attached, an electrical contact 19 is resilient in the radial direction in an electrically conductive connection with the corresponding shaping of the metal wire 18 Metal pipe occurs. Electrostatic charges occurring on the metal tube during suction operation are thus conveyed directly to the operator by their engagement with the electrical conductor 18, so that electrostatic charges are discharged via the operator during operation or at least there is no voltage potential difference when the handle 8 is detected with the other hand the metallic suction pipe is touched. The socket 16 is otherwise fixed on the one hand on a bracket 20 provided on the coupling section 15 and on the other hand within the half-shells 3.
