Description

Die Erfindung betrifft ein transportables Reinigungsgerät wie es im Oberbegriff von Anspruch 1 gekennzeichnet ist.The invention relates to a portable cleaning device as characterized in the preamble of claim 1.

Bekannt ist ein Gerät, bei welchem die Reinigungswerkzeuge bzw. die Bürsten über ein, an einem Gestell befestigten Getriebe mittels eines an das Stromleitungsnetz anschliessbaren Elektromotors antreibbar sind. Da dieses Gerät vom Stromleitungsnetz abhängig ist, kann es meist nicht bei der Installation von Sanitär- und Heizungsanlagen in Neubauten verwendet werden, da hier sehr oft noch keine Stromanschlüsse vorhanden sind.A device is known in which the cleaning tools or the brushes can be driven via a gear attached to a frame by means of an electric motor that can be connected to the power line network. Since this device is dependent on the power supply network, it can usually not be used for the installation of sanitary and heating systems in new buildings, since very often there are no power connections.

Auch bei vorhandenen Stromanschlüssen ist es oft sehr umständlich, das Gerät jeweils zum Arbeitsort zu bringen, da es durch die Gestell-Bauweise relativ schwer ist und bei beschränkten Platzverhältnissen nicht immer aufstellbar ist. lnsbesonders dann, wenn Rohrenden bereits verlegter Rohre zum Reinigen sind, kann dieses Gerät nicht verwendet werden.Even with existing power connections, it is often very cumbersome to bring the device to the place of work, since the frame construction makes it relatively difficult and it is not always possible to set it up when space is limited. This device cannot be used, especially if pipe ends of pipes that have already been laid are to be cleaned.

Hierfür müssen vom Installateur unterschiedliche Hand-Reinigungsmittel wie z.B. Handbürsten für die Aussen- und Innenreinigung oder Stahlwolle nacheinander verwendet werden, was sehr zeitaufwendig ist.To do this, the installer must use different hand cleaning agents such as Hand brushes for external and internal cleaning or steel wool can be used one after the other, which is very time consuming.

Ein dem Oberbegriff von Anspruch 1 gattungsmässig entsprechendes Reinigungsgerät für rohrförmige Teile ist durch die US-PS 4 238 867 bekannt geworden. Nachteilig hierbei ist, dass an jeder Stirnseite des Gehäuses jeweils ein Reinigunswerkzeug angeordnet ist, wobei beide Werkzeuge gemeinsam antreibbar sind. Dadurch ist eine unfallsichere, einfache und schnelle Handhabung des Gerätes nicht gewährleistet. Die am Umfang des Gehäuses angeordneten Batterien ermöglichen ebenfalls keine handhabungsgerechte Ausbildung des Gerätes.A cleaning device for tubular parts corresponding to the preamble of claim 1 is known from US Pat. No. 4,238,867. The disadvantage here is that a cleaning tool is arranged on each end face of the housing, both tools being drivable together. This means that the device cannot be used safely, easily and quickly. The batteries arranged on the circumference of the housing likewise do not allow the device to be designed to be suitable for handling.

Aufgabe der vorliegenden Erfindung ist die Schaffung eines Reinigungsgerätes der eingangs genannten Art, welches trotz motorisch antreibbaren Reinigungswerkzeugen eine sichere und einfache Handhabung gewährleistet.The object of the present invention is to provide a cleaning device of the type mentioned, which ensures safe and simple handling despite motor-driven cleaning tools.

Erfindungsgemäss wird dies durch die im Anspruch 1 angeführten kennzeichnenden Merkmale gelöst.According to the invention, this is solved by the characterizing features stated in claim 1.

Besonders vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen gekennzeichnet.Particularly advantageous configurations are characterized in the dependent claims.

Die erfindungsgemässen Merkmale ermöglichen das Reinigen des Innen- und Aussendurchmessers einer Rohrabmessung unmittelbar hintereinander ohne irgendwelche Griffwechsel, so dass ein schnelles und sicheres Handhaben des Reinigungsgerätes gewährleistet ist.The features according to the invention make it possible to clean the inside and outside diameter of a pipe dimension immediately one behind the other without any change of handles, so that the cleaning device can be handled quickly and safely.

Die Erfindung ist anhand eines Ausführungsbeispieles in den beiliegenden Zeichnungen dargestellt und nachfolgend beschrieben.The invention is illustrated using an exemplary embodiment in the accompanying drawings and described below.

Es zeigen:

  • Fig. 1 einen Längsschnitt durch ein Reinigungsgerät und
  • Fig. 2 eine Ansicht von vorn.
Show it:
  • Fig. 1 shows a longitudinal section through a cleaning device and
  • Fig. 2 is a front view.

Das in den Fig. 1 und 2 gezeigte Reinigungsgerät für rohrförmige Teile weist ein Gehäuse 1 auf, von dem ein Teil als Handgriff 2 ausgebildet ist. Im Gehäuse 1 ist ein kleiner Elektromotor 3, eine Energiequelle 4 für den Elektromotor 3, welche aus Batterien oder aufladbaren Akkumulatoren besteht, und ein Getriebe 5 mit zwei Ausgangswellen 6 angeordnet.The cleaning device for tubular parts shown in FIGS. 1 and 2 has a housing 1, a part of which is designed as a handle 2. A small electric motor 3, an energy source 4 for the electric motor 3, which consists of batteries or rechargeable batteries, and a gear 5 with two output shafts 6 are arranged in the housing 1.

Ein auf der Motorwelle 7 angeordnetes Zahnrad 8 steht mit zwei Zahnrädern 9 in Eingriff, welche an den beiden Ausgangswellen 6 drehfest angeordnet sind. Die beiden Ausgangswellen 6 ragen stirnseitig aus dem Gehäuse 1 hinaus und sind zur Befestigung von Reinigungswerkzeugen 10 ausgebildet.A gearwheel 8 arranged on the motor shaft 7 is in engagement with two gearwheels 9, which are arranged on the two output shafts 6 in a rotationally fixed manner. The two output shafts 6 protrude from the front of the housing 1 and are designed for fastening cleaning tools 10.

In dem gezeigten Ausführungsbeispiel sind die Reinigungswerkzeuge 10 als Bürsten ausgebildet, wobei die Bürste 11 zurAussenreinigung eines Fittings oder Rohrendes 13 einen kreiszylindrischen Mantel 14 aufweist an dessen innerem Umfang radial einwärts gerichtete Borsten 15 befestigt sind. Für die Innenreinigung des gleichen Fittings bzw. Rohrendes 13 wird eine konventionelle Bürste 12 mit an einer Welle 16 befestigten und radial nach aussen gerichteten Borsten 17 verwendet. An Stelle von Borsten 15 kann beispielsweise auch ein Reinigungsvlies angeordnet werden. Bei der Bürste 11 werden die Borsten 15 vorzugsweise in vier getrennten, jeweils um 90° zueinander versetzten Reihengruppen angeordnet.In the exemplary embodiment shown, the cleaning tools 10 are designed as brushes, the brush 11 for the external cleaning of a fitting or pipe end 13 having a circular cylindrical jacket 14, on the inner circumference of which radially inwardly directed bristles 15 are fastened. For the internal cleaning of the same fitting or pipe end 13, a conventional brush 12 with bristles 17 fastened to a shaft 16 and directed radially outwards is used. Instead of bristles 15, a cleaning fleece can also be arranged, for example. In the case of the brush 11, the bristles 15 are preferably arranged in four separate rows, each offset by 90 ° to one another.

Die Reinigungswerkzeuge können auch als Polier-, Schleifoder Entgratungs-Werkzeuge ausgebildet sein. Da für unterschiedliche Fittings bzw. Rohrabmessungen jeweils entsprechende Reinigungswerkzeuge wie z.B. Bürsten mit den entsprechenden Durchmessern erforderlich sind, sollten diese leicht auswechselbar sein.The cleaning tools can also be designed as polishing, grinding or deburring tools. Since different cleaning tools such as e.g. Brushes with the appropriate diameters are required, these should be easy to replace.

Dies wird vorteilhafterweise durch drehfeste Verbindungen 18 zwischen der Ausgangswelle 6 und dem Reinigungswerkzeug 10 erreicht, welche in bekannter Weise als Steck-, Schraub- oder bajonettartige Schnell-Verbindungen ausgebildet sein können.This is advantageously achieved by non-rotatable connections 18 between the output shaft 6 and the cleaning tool 10, which can be designed in a known manner as plug-in, screw or bayonet-type quick connections.

Am Handgriff 2 ist ein Ein-Aus-Schalter 19 angeordnet, so dass das Gerät mit einer Hand gehalten und betätigt werden kann.An on-off switch 19 is arranged on the handle 2, so that the device can be held and operated with one hand.

Am Ende des Handgriffes 2 ist ein abnehmbarer Deckel 20 angeordnet, so dass die im Handgriff angeordneten Batterien leicht ausgewechselt werden können. Werden Akkumulatoren verwendet, so ist der Deckel bzw. das Gehäuse vorteilhafterweise mit einer Einrichtung für das Aufladen der Akkumulatoren versehen.A removable cover 20 is arranged at the end of the handle 2, so that the batteries arranged in the handle can be easily replaced. If batteries are used, the cover or the housing is advantageously provided with a device for charging the batteries.

Die beiden Reinigungswerkzeuge 10 sind durch eine Schutzhaube 21 umfangseitig abgedeckt, welche entweder abnehmbar am Gehäuse 1 befestigt ist oder mit diesem eine Einheit bildet.The two cleaning tools 10 are covered on the circumferential side by a protective hood 21, which is either removably attached to the housing 1 or forms a unit with the latter.

Das erfindungsgemässe Reinigungsgerät kann, da es durch die eigene als Batterie oder Akkumulator ausgebildete Energiequelle unabhängig vom Energienetz ist, an den jeweiligen Verwendungsort gebracht werden und ist nicht an einen Arbeitsplatz gebunden.The cleaning device according to the invention, since it is independent of the energy network due to its own energy source designed as a battery or accumulator, can be brought to the respective place of use and is not tied to a workplace.

Als Kleinstgerät kann es mit einer Hand gehalten und bedient werden, so dass mit der ahderen Hand, falls erforderlich, der Fitting bzw. das Rohrende gehalten werden kann.As a small device, it can be used with one hand are held and operated so that the fitting or the pipe end can be held with the other hand, if necessary.

Für einen Dimensionswechsel sind die Reinigungswerkzeuge leicht auswechselbar.The cleaning tools are easily exchangeable for changing dimensions.

Die Reinigung des Aussendurchmessers und des Innendurchmessers von Fittings bzw. Rohrenden, insbesondere als Vorbereitung zum Weichlöten, sind sofort hintereinander ohne Wechsel der Werkzeuge möglich, so dass sehr kurze und durch den motorischen Antrieb den Arbeiter wenig belastende Reinigungszeiten gewährleistet sind.The cleaning of the outside diameter and the inside diameter of fittings or pipe ends, in particular as preparation for soft soldering, can be carried out immediately one after the other without changing the tools, so that very short cleaning times, which are not very stressful for the worker due to the motor drive, are guaranteed.

Werden als Energiequelle Akkumulatoren verwendet, so können diese in Arbeitspausen z.B. während der Nacht über einen Trafo am elektrischen Netz aufgeladen werden.If accumulators are used as the energy source, they can be used during breaks, e.g. be charged at night via a transformer on the electrical network.
