Description

Die Erfindung betrifft ein mit einem stielartigen, hohlen Handstück versehenes, zum Reinigen insbesondere von Fensterscheiben dienendes Reinigungsgerät mit einem auswechselbaren, etwa streifenförmigen Reinigungswerkzeug, das zwischen zwei relativ zueinander verstellbaren Klemmbacken gehalten ist, von denen die eine Klemmbacke mit einem Fortsatz mit dem Handstück mittels einer Gelenkschraube verbunden ist.The invention relates to a cleaning device provided with a handle-like, hollow handpiece, for cleaning in particular window panes, with an exchangeable, approximately strip-shaped cleaning tool, which is held between two relatively adjustable clamping jaws, one of which has a jaw with an extension with the handpiece by means of a Joint screw is connected.

Derartige Reinigungsgeräte, die mit ihrem Handstück in eine vorzugsweise teleskopierbare Griffstange einsetzbar sind und deren Klemmbacken mit dem Reinigungswerkzeug verschwenkbar sind, sind bekannt. Die Klemmbacken sind für den Fall, daß der das Gerät Handhabende vor der zu reinigenden Fensterscheibe seinen Standort hat, zu dem Handstück bzw. der Griffstange rechtwinklig angeordnet. Der das Gerät Handhabende kann für diesen Fall die Fensterscheibe in Bahnen von oben nach unten rationell reinigen. Ist dagegen der das Gerät Handhabende aufgrund räumlicher Gegebenheiten gezwungen, seitlich zu der zu reinigenden Fensterscheibe seinen Standort zu beziehen, so können durch die durch den Standort erzwungene schräge Haltung des Handstückes bzw. der Griffstange die Klemmbacken zu ersteren in einem Winkel so eingestellt werden, daß die Fensterscheibe ebenfalls in Bahnen von oben nach unten gereinigt werden kann. Bei den bekannten Reinigungsgeräten können zwar die Klemmbacken mit dem Reinigungswerkzeug mittels der Gelenkschraube zu einem gewissen Grad in der jeweiligen Winkellage festgeklemmt werden. Die Klemmung reicht jedoch nicht aus, unbeabsichtigtes Versetzen der Klemmbacken während des Reinigens der Fensterscheibe zu vermeiden.Such cleaning devices, which can be used with their handpiece in a preferably telescopic handle bar and whose jaws can be pivoted with the cleaning tool, are known. The clamping jaws are arranged at right angles to the handpiece or the handlebar in the event that the person handling the device is in front of the window pane to be cleaned. In this case, the person handling the device can rationally clean the window pane in lanes from top to bottom. If, on the other hand, the person handling the device is forced to relate its location laterally to the window pane to be cleaned, the oblique position of the handpiece or the handle bar, forced by the location, allows the jaws to be set at an angle to the former the window glass can also be cleaned in lanes from top to bottom. In the known cleaning devices, the clamping jaws can be clamped to a certain degree in the respective angular position with the cleaning tool by means of the hinge screw. However, the clamping is not sufficient to avoid unintentional displacement of the clamping jaws when cleaning the window pane.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein Reinigungsgerät der eingangs genannten Gattung so weiter auszubilden, daß die Klemmbacken mit dem Reinigungswerkzeug in der jeweils eingestellten Lage zu dem Griffstück bzw. der Griffstange auf einfache Weise so feststellbar sind, daß unbeabsichtigtes Versetzen der Klemmbacken mit Sicherheit vermieden ist.In contrast, the invention has for its object to further develop a cleaning device of the type mentioned so that the clamping jaws with the cleaning tool in the respectively set position to the handle or the handle bar can be easily determined so that unintentional displacement of the jaws with certainty is avoided.

Die Lösung der Aufgabe besteht erfindungsgemäß darin, daß der Fortsatz der einen Klemmbacke mit einer Verlängerung des Handstückes gelenkig verbunden ist und an seiner der Verlängerung abgekehrten Breitseite eine bogenförmige relativ grobe Verzahnung aufweist, die in an sich bekannter Weise mit einem in dem Handstück geführten, als Schieber ausgebildeten, federbelasteten Arretierhebel in Wirkverbindung steht.The solution to the problem is according to the invention that the extension of the one jaw is articulated to an extension of the handpiece and has on its broad side facing away from the extension a curved, relatively coarse toothing, which in a known manner with a guided in the handpiece as Slide trained, spring-loaded locking lever is in operative connection.

Der Arretierhebel wird zum Arretieren der Klemmbacken durch Schiebedruck auf seine Handhabe entgegen der Wirkung der den Arretierhebel belastenden Druckfeder aus dem vorderen offenen Ende des Griffstückes herausgechoben und in eine der Lage der Klemmbacken zu dem Handstück entsprechende Zahnlücke der groben Verzahnung eingerastet, in der er bei nachlassendem Druck auf die Handhabe in der Rastlage gesichert ist. Die Klemmbacken mit dem Reinigungskörper sind dadurch vor unbeabsichtigtem Versetzen während des Reinigens der Fensterscheibe gesichert.To lock the clamping jaws, the locking lever is pushed out of the front open end of the grip piece against the effect of the compression spring loading the locking lever by sliding pressure on its handle and is locked into a tooth gap of the coarse toothing corresponding to the position of the clamping jaws relative to the handpiece, in which it loosens when the grip decreases Pressure on the handle is secured in the locked position. The jaws with the cleaning body are thereby secured against unintentional movement while cleaning the window pane.

Eine vorteilhafte Weiterbildung der Erfindung besteht darin, daß die Zähne der Verzahnung an ihren stumpfen Stirnseiten eine Feinverzahnung aufweisen und der Arretierhebel an seinem vorderen Ende einen zahnartigen Vorsprung aufweist, mit dem er mit der Feinverzahnung in Wirkverbindung steht.An advantageous development of the invention is that the teeth of the toothing have fine toothing on their blunt faces and the locking lever has a tooth-like projection at its front end with which it is in operative connection with the fine toothing.

Für den Fall, daß mittels der groben Verzahnung die Arretierung der Klemmbacken in der eingestellten Lage nicht möglich ist, erfolgt die Arretierung mit Hilfe der Feinverzahnung.In the event that it is not possible to lock the clamping jaws in the set position by means of the coarse toothing, the locking takes place with the help of the fine toothing.

Die Erfindung ist nachstehend in einem Ausführungsbei­spiel anhand der Zeichnung näher erläutert. Es zeigt:

  • Figur 1 das Reinigungsgerät ohne Reinigungswerkzeug in Rückansicht, teilweise aufgerissen,
  • Figur 2 einen Schnitt nach der Linie A-A der Figur 1 und
  • Figur 3 die beiden Klemmbacken mit Reinigungswerkzeug in Seitenansicht.

Das Reinigungsgerät besteht aus einem Kopf 1, der sich aus zwei Klemmbacken 2,3 zusammensetzt. Die Klemmbacke 3 ist mit der Klemmbacke 2 mittels Schrauben 4 verbunden, die die Klemmbacke 3 mit Spiel durchsetzen. Auf die Gewindeenden der Schrauben 4 sind Muttern 5 aufgeschraubt, die die Klemmbacke 3 auf den Schrauben 4 sichern. Die Klemmbacke 3 weist am hinteren Ende eine federnde Abbiegung 6 auf, die an der einen Seite der Klemmbacke 2 abgestützt ist. Nach Lösen der Muttern 5 wird die Klemmbacke 3 durch die Wirkung der vorher gespannten und sich nunmehr entspannenden Abbiegung 6 so weit von der Klemmbacke 2 abgedrückt, daß das Reinigungswerkzeug bequem ausgewechselt werden kann. Die Abbiegung 6 ist nicht zwingend erforderlich und kann auch entfallen. Mit 7 ist ein auswechselbares Reinigungswerkzeug in Form eines aus gummielastischem Werkstoff gefertigten Abstreifers bezeichnet, das in einer Fassung 8 U-förmigen Querschnitts eingesetzt ist. Das Reinigungswerkzeug 7 ist mit seiner Fassung 8 zwischen den Klemmbacken 2,3 gehalten (Figur 3). Mit 9 ist ein Handstück bezeichnet, das am vorderen Ende eine mit dem Handstück 9 einen Absatz 1o bildende Verlängerung 11 aufweist, die mit dem Handstück 9 einstückig aus Kunststoff hergestellt ist. Die Klemmbacke 2 liegt mit einem Fortsatz 12 an der Innenseite der Verlängerung 11 an. Der Fortsatz 12 weist einen hohlzylindrischen, mit einem Durchgangsloch 13 in dem Fortsatz 12 koaxialen Halsansatz 14 mit glatter Innenwandung auf, mit dem sie in der Verlängerung 11 des Handstückes 9 schwenkbar gelagert ist. Mit 15 ist eine die Klemmbacke 2 mit dem Handstück 9 bzw. dessen Verlängerung 11 verbindende Gelenkschraube bezeichnet, die mit ihrem Gewindeschaft den Halsansatz 14 und das Durchgangsloch 13 durchsetzt und in eine in dem Fortsatz 12 der Klemmbacke 2 drehfest angeordnete Mutter 16 eingeschraubt ist. Durch Anziehen der Gelenkschraube 15 gegen die Verlängerung 11 des Handstückes 9 wird die Klemmbacke 2 mit der Verlängerung 11 schwergängig verbunden.The cleaning device consists of a head 1, which is composed of two clamping jaws 2, 3. The clamping jaw 3 is connected to the clamping jaw 2 by means of screws 4 which pass through the clamping jaw 3 with play. Nuts 5, which secure the clamping jaw 3 on the screws 4, are screwed onto the threaded ends of the screws 4. The jaw 3 has at the rear end a resilient bend 6, which is supported on one side of the jaw 2. After loosening the nuts 5 the jaw 3 is pushed by the action of the previously tensioned and now relaxing bend 6 so far from the jaw 2 that the cleaning tool can be easily replaced. The turn 6 is not absolutely necessary and can also be omitted. 7 with an interchangeable cleaning tool in the form of a scraper made of rubber-elastic material, which is used in a socket 8 U-shaped cross section. The cleaning tool 7 is held with its socket 8 between the clamping jaws 2, 3 (FIG. 3). 9 with a handpiece is designated, which has at the front end with the handpiece 9 a paragraph 10 forming an extension 11, which is made in one piece with the handpiece 9 from plastic. The jaw 2 rests with an extension 12 on the inside of the extension 11. The extension 12 has a hollow cylindrical, with a through hole 13 in the extension 12 coaxial neck extension 14 with a smooth inner wall, with which it is pivotally mounted in the extension 11 of the handpiece 9. 15 denotes a hinge screw connecting the clamping jaw 2 with the handpiece 9 or its extension 11, the threaded shaft penetrating the neck extension 14 and the through hole 13 and being screwed into a nut 16 arranged in a non-rotatable manner in the extension 12 of the clamping jaw 2. By tightening the hinge screw 15 against the extension 11 of the handpiece 9, the jaw 2 is connected to the extension 11 with difficulty.

An der der Verlängerung 11 des Handstückes 9 abgekehrten Breitseite des Fortsatzes 12 der Klemmbacke 2 ist eine bogenförmige grobe Verzahnung 17 erzeugt, deren Zähne 18 an ihren stumpfen Stirnseiten eine Feinverzahnung 19 aufweisen. In dem hohlen Handstück 9 ist ein als Schieber ausgebildeter Arretierhebel 2o geführt, der an seinem vorderen Ende eine nach einwärts gerichtete Verbreiterung 21 aufweist. Der Arretierhebel 2o besitzt an seinem vorderen Ende einen zahnartigen Vorsprung 22. Er durchsetzt mit einer hohlzylindrischen Handhabe 23 ein sich in der Wandung des Handstückes 9 längser­streckendes Langloch 24. Die Handhabe 23 ragt mit ihrem hinteren Ende bis in das Innere des Handstückes 9. Mit 25 ist eine U-förmig gebogene, vorgespannte Druckfeder bezeichnet, die mit ihrem Schenkel 26 an der Innenwandung des Handstückes 9 anliegt und mit ihrem Schenkel 27 an einem in das hintere Ende der Handhabe 23 fest eingesetzten Einsatz 28 befestigt ist. Die Druckfeder 25 kann auch mit der Handhabe 23 ein­stückig aus Kunststoff hergestellt sein.On the broad side of the extension 11 of the handpiece 9 facing away from the extension 12 of the clamping jaw 2, an arc-shaped coarse toothing 17 is produced, the teeth 18 of which have fine toothing 19 on their blunt end faces exhibit. In the hollow handpiece 9, a locking lever 20 designed as a slide is guided, which has an inward widening 21 at its front end. The locking lever 2o has a tooth-like projection 22 at its front end. With a hollow cylindrical handle 23, it extends through an elongated hole 24 in the wall of the handpiece 9. The rear end 23 of the handle 23 extends into the interior of the handpiece 9. At 25 is a U-shaped, biased compression spring called, which rests with its leg 26 on the inner wall of the handpiece 9 and is attached with its leg 27 to an insert 28 firmly inserted into the rear end of the handle 23. The compression spring 25 can also be made in one piece from the plastic with the handle 23.

Die Klemmbacken 2,3 des Reinigungsgerätes sind für gewöhnlich rechtwinklig zu dem Handstück 9 angeordnet. Zum Verändern der Winkellage der Klemmbacken 2,3 bzw. des Reinigungswerkzeuges 7 zu dem Handstück 9 wird der Arretierhebel 2o durch Schiebedruck auf seine Handhabe 23 aus der Verzahnung 17 ausgerastet, wonach die Klemmbacken 2,3 in die gewünschte Winkellage ver­schwenkt werden. Hiernach wird der Arretierhebel 2o durch Schiebedruck auf seine Handhabe 23 in eine der Winkellage der Klemmbacken 2,3 entsprechende Zahnlücke der Verzahnung 17 eingerastet. Der Arretierhebel 2o ist in beiden Rastlagen durch die Druckfeder 25 ge­sichert. Falls eine Arretierung der Klemmbacken 2,3 in der eingestellten Winkellage mit Hilfe der Ver­zahnung 17 nicht möglich ist, wird die Feinverzahnung 19 zu Hilfe genommen, in die der Arretierhebel 2o mit seinem Vorsprung 22 eingerastet bzw. in der vorbe­schriebenen Weise aus der Feinverzahnung 19 ausgerastet wird.The clamping jaws 2, 3 of the cleaning device are usually arranged at right angles to the handpiece 9. To change the angular position of the clamping jaws 2, 3 or the cleaning tool 7 relative to the handpiece 9, the locking lever 2o is disengaged from the toothing 17 by pushing on its handle 23, after which the clamping jaws 2, 3 are pivoted into the desired angular position. Thereafter, the locking lever 2o is engaged by pushing the handle 23 into a tooth gap of the toothing 17 corresponding to the angular position of the clamping jaws 2,3. The locking lever 2o is secured in both locking positions by the compression spring 25. If it is not possible to lock the clamping jaws 2, 3 in the set angular position with the aid of the toothing 17, the fine toothing 19 is used, into which the locking lever 2o engages with its projection 22 or disengaged from the fine toothing 19 in the manner described above becomes.
