Description

Die vorliegende Erfindung betrifft eine, Bürste insbesondere zum Reinigen von Toilettenbecken, welche aus einem Stiel besteht, an dessen einem Ende ein Handgriff und an dessen anderem Ende eine Vielzahl von Borsten angeordnet sind.The present invention relates to a brush, in particular for cleaning toilet bowls, which consists of a stem with a handle at one end and the other end a plurality of bristles are arranged.

Um sicherzustellen, daß Toilettenbecken nicht Brutstätten für Sporen und Bakterien sind, befinden sich eine Anzahl von WC- Reinigern im Handel, deren wirksame Chemikalien saure Salze, beispielsweise Hydrogensulfate, oder Tenside sind. Saure Abwässer beeinträchtigen jedoch die biologische Stufe in Kläranlagen, während Tenside mikrobiologisch schwer abbaubar sind.To ensure that toilet bowls are not breeding grounds for spores and bacteria, There are a number of toilet cleaners on the market whose effective chemicals are acidic Salts, for example hydrogen sulfates, or surfactants. However, acidic waste water affects the biological level in sewage treatment plants, while surfactants are difficult to biodegrade.

Wegen der geschilderten Nachteile sind nur mechanische Mittel zur Freihaltung der Toilettenbecken von Schmutz als Brutstätten für Sporen und Bakterien geeignet. Dabei ist ein großer Teil der bekannten Bürsten lediglich zur Reinigung der von außen sichtbaren Teile des Toilettenbeckens geeignet. Darüber hinaus ist aus der Offenlegungsschrift DE 43 45 118 A1 eine zum Reinigen von Toilettenschüsseln geeignete Bürste bekannt, welche aus einem Bürstenstiel mit einem Handgriff an seinem einen Ende und mit einem Borstenbereich an seinem anderen Ende besteht. Dabei ist ein erster Teil des Borstenbereiches am Stiel gerade angeordnet, während ein anderer Teil des Borstenbereiches abgebogen ist, wobei beide Teile einen spitzen Winkel einschließen.Because of the disadvantages described, there are only mechanical means for keeping the toilet bowl free of dirt as a breeding ground for spores and bacteria. There is a big part the known brushes only for cleaning the parts of the toilet bowl visible from the outside suitable. In addition, the published patent application DE 43 45 118 A1 for Cleaning toilet bowls suitable brush known, which with a brush handle a handle at one end and a bristle area at its other end consists. A first part of the bristle area is arranged straight on the stem, while a other part of the bristle area is bent, both parts enclosing an acute angle.

Aus der DE-U-92 03 566 ist eine biegsame Klosettbürste mit auswechselbarem Bürstenkopf bekannt, bei welcher zwischen Bürstenstiel und Bürstenkopf eine mit Kunststoff beschichtete oder aus Edelstahl bestehende Feder angeordnet ist. Dabei kann die Feder mit ihrem unteren Ende in eine Scheibe eingesetzt sein, welche an ihrer der Feder angewandten Seite einen Gewindestift aufweist. Dieser Gewindestift ist in eine mit Gewinde versehene Ausnehmung im Bürstenkopf einschraubbar und mit Hilfe einer die Scheibe durchdringenden und im Bürstenkopf endenden Schraube arretierbar.DE-U-92 03 566 describes a flexible toilet brush with a replaceable one Brush head known, in which one between the brush handle and brush head Plastic coated or stainless steel spring is arranged. It can the spring with its lower end can be inserted into a disc, which at its the Spring applied side has a grub screw. This grub screw is in one threaded recess can be screwed into the brush head and with the help of a the screw penetrating and ending in the brush head lockable.

Aufgabe der vorliegenden Erfindung ist es, eine Bürste anzugeben, welche so ausgestaltet ist, daß damit Toilettenbecken vollständig gereinigt werden können, insbesondere auch das einen Teil des Geruchsverschlusses bildende, horizontal angeordnete Ablaufrohr im unteren Bereich des Toilettenbeckens.The object of the present invention is to provide a brush which is designed such that so that toilet bowls can be completely cleaned, especially a part of the Odor trap, horizontally arranged drain pipe in the lower area of the Toilet bowl.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Stiel aus einem Oberteil und einem Unterteil besteht, wobei das Oberteil mit dem Handgriff verbunden ist und wobei das Unterteil an seinem dem Oberteil abgewandten Ende mit der Vielzahl von Borsten versehen ist; daß das Oberteil eine Ausnehmung aufweist; dass das Unterteil mit einem Zapfen versehen ist; und dass der obere Bereich des Unterteiles aus einem Gummi-Metall-Puffer besteht, wobei der Gummi Shore-Härten von 20 bis 90 aufweist.The object is achieved in that the handle from an upper part and a The lower part consists of the upper part being connected to the handle and the lower part is provided with the plurality of bristles at its end facing away from the upper part; that this Upper part has a recess; that the lower part is provided with a pin; and that the upper area of the lower part consists of a rubber-metal buffer, wherein the rubber shore hardness is from 20 to 90.

Dabei kann als Gummi Naturkautschuk oder Neopren verwendet sein. Weiterhin kann die Ausnehmung zentrisch oder azentrisch in das Oberteil eingearbeitet sein; in die Ausnehmung kann ein Gewinde eingeschnitten sein. Schließlich kann der Zapfen zentrisch oder azentrisch in das Unterteil eingesetzt und mit einem Gewinde versehen sein.Natural rubber or neoprene can be used as the rubber. Furthermore can the recess can be machined centrally or eccentrically into the upper part; in the A thread can be cut into the recess. Finally, the spigot inserted centrically or eccentrically into the lower part and provided with a thread his.

Bei der erfindungsgemäßen Bürste ist von Vorteil, daß das den Borstenbereich tragende Unterteil bei Verschleiß oder starker Verschmutzung der Borsten gegen ein neues Unterteil unter Weiterbenutzung von Oberteil und Handgriff ausgetauscht werden kann. In the brush according to the invention it is advantageous that the lower part carrying the bristle area if the bristles are worn or heavily soiled against a new lower part Further use of the upper part and handle can be exchanged.
