Description

Die Erfindung betrifft eine Fensterreinigungsgerät gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a window cleaning device according to the preamble of claim 1.

Fensterreinigungsgeräte sollten so konzipiert sein, daß sie es ermöglichen, in einer möglichst kurzen Zeit eine möglichst große Fensterfläche, ohne Gefährdung oder Verschmutzung anderer Teile zu säubern.Window cleaning devices should be designed in such a way that they enable the largest possible window area to be cleaned in the shortest possible time without endangering or contaminating other parts.

Es ist ein Fensterreinigungsgerät bekannt mit einer Rückenprofilleiste, an deren einer Seite ein seitlich verschieb- und auswechselbares Wischerblatt sowie parallel dazu ein langgestreckter, fellartigen Anfeuchter und an deren anderer Seite ein Handgriff befestigt sind. (DE-U-7 624 786).A window cleaning device is known with a back profile strip, on one side of which a laterally displaceable and exchangeable wiper blade and, parallel thereto, an elongated, fur-like moistener and on the other side of which a handle is attached. (DE-U-7 624 786).

Nachteilig ist bei diesem vorbekannten Fensterreinigungsgerät, daß der Anfeuchter zwar aus einem nicht näher bezeichneten Fell besteht, das aber nur in einer einfachen Schicht über einen Tragestab. angeordnet ist. Eine derartig dünne Fellschicht kann auch nur wenig Wasser speichern. Da das Fell zudem frei liegt, besteht auch die Gefahr, daß die Reinigungsflüssigkeit die Scheibe hinunterlaufen kann sowie beim Handhaben des Gerätes die Fensterbretter und c'gl. verunreinigt. Die Befestigung des Fells bei dem vorbekannten Fensterreinigungsgerät ist schwierig, weil das schlauchartig ausgebildete Fell auf den Stab aufgezogen werden muß, wobei noch unklar bleibt, wie die Rückenprofilleiste das Fell durchsetzen soll.The disadvantage of this known window cleaning device is that the humidifier consists of a fur, not specified, but only in a simple layer via a carrying rod. is arranged. Such a thin layer of fur can only store a little water. Since the fur is also exposed, there is also the risk that the cleaning liquid can run down the window and when handling the device the window sills and the like. contaminated. The attachment of the skin in the previously known window cleaning device is difficult because the tube-like skin has to be pulled onto the rod, it still being unclear how the back profile strip is to penetrate the skin.

Die dem Anmelgungsgegenstand zugrundeliegende Aufgabe besteht darin, ein Fensterreinigungsgerät der bekannten Art zu Schaffen, bei dem der Anfeuchter einfach und schnell befestigbar ist, ein großes Wasserspeicher- und Haltevermögen ohne Gefahr der Umgebungsverschmutzung aufweist und zudem den Schmutz-und Fettfilm auf Fensterscheiben wirksam aufzubrechen vermag.The object on which the application is based consists in creating a window cleaning device of the known type in which the humidifier can be easily and quickly attached, has a large water storage and holding capacity without the risk of environmental pollution and, moreover, can effectively break up the dirt and grease film on window panes.

Diese Aufgabe wurde gelöst durch das Fensterreinigungsgerät gemäß dem kennzeichnenden Teil des Patentanspruchs 1.This object was achieved by the window cleaning device according to the characterizing part of patent claim 1.

Weitere vorteilhafte Ausgestaltungen des erfindungsgemäBen Gerätes sind in den kennzeichnenden Teilen der Ansprüche 2 bis 4 beschrieben.Further advantageous refinements of the device according to the invention are described in the characterizing parts of claims 2 to 4.

. Mit einem Fensterreinigungsgerät gemäß dem Patentanspruch 1 ist folgendes erreicht : Das kernlos gewickelte Kunststoffell vermag größere Wassermengen wirksam zu speichern. Es sind nämlich mehrere Schichten saugfähigen Felles vorhanden, besonders wirksam dann, wenn die Trägerbahn entsprechend saugfähig ausgebildet ist, wie das bei einem Kunststoffell ohne weiteres möglich ist. Werden zudem die Haare des Kunststoffells genügend hart ausgebildet, so wird ein derartiges Kunststoffell den Schmutz- und Fettfllm auf der Fensterscheibe wirksam aufzureiBen vermögen. Durch das Einlegen des gewickelten Kunststoffells in eine konkave Mulde des Anfeuchters ist die Voraussetzung für eine sehr einfache Befestigung gegeben. Das Vorziehen der dem Wischerblatt abgewandten Kante nach vorn auf die Fensterscheibe hin bewirkt, daß das im Fell gespeicherte Wasser nicht ohne weiteres nach unter austreten kann.. With a window cleaning device according to claim 1, the following is achieved: The corelessly wound plastic cell can effectively store large amounts of water. This is because there are several layers of absorbent skin, particularly effective when the carrier web is designed to be absorbent, as is readily possible with a synthetic skin. In addition, if the hair of the plastic cell is made sufficiently hard, such a plastic cell will be able to effectively remove the dirt and grease film on the window pane. By inserting the wound plastic cell into a concave hollow of the humidifier, the prerequisite for very simple attachment is given. The pulling forward of the edge facing away from the wiper blade towards the window pane means that the water stored in the skin cannot easily exit below.

Im Anspruch 2 sind verschiedene Möglichkeiten aufgezeigt, den Anfeuchter auswechselbar oder fest an der Rückenprofilleiste zu haltern, was zu einer wirtschaftlichen, zeitsparenden Fertigung führt.In claim 2 different possibilities are shown to replace the humidifier or to hold it firmly on the back profile strip, which leads to economical, time-saving production.

Anspruch 3 zeigt eine sehr einfache Möglichkeit, das gesamte Gerät zusammenzuhalten. Dabei ergibt sich auch eine einfache Möglichkeit den Handgriff seitlich zu verschieben, wie Anspruch 4 zeigt. Der seitlich verschiebbare Handgriff ermöglicht ein gutes Reinigen der Scheiben auch hinter Heizkörpern und dgl.Claim 3 shows a very simple way to hold the entire device together. There is also a simple possibility to move the handle laterally, as shown in claim 4. The laterally displaceable handle enables the windows to be cleaned well, even behind radiators and the like.

Endlich ist im Anspruch 5 dargelegt, daß das Gerät auch zu seinem Handgriff verschwenkt werden kann, was besonders dann zweckmäßig ist, wenn höhere Arbeitsflächen erreicht werden sollen, da dann die Rückenprofilleiste mit dem Anfeuchter und dem Wischerblatt in eine annähernd senkrechte Stellung gedreht werden kann.Finally, it is stated in claim 5 that the device can also be pivoted to its handle, which is particularly expedient if higher work surfaces are to be achieved, since the back profile strip can then be rotated into an approximately vertical position with the humidifier and the wiper blade.

Die Zeichnung erläutert den Erfindungsgegenstand an einem Ausführungsbeispiel.The drawing explains the subject of the invention using an exemplary embodiment.

Es zeigt :

  • - Figur 1 eine Teil-Rückenansicht und
  • - Figur 2 eine Seitenansicht des Gerätes.
It shows :
  • - Figure 1 is a partial rear view and
  • - Figure 2 is a side view of the device.

Der Handgriff 1 ist über die Kugel 2, allseitig schwenkbar, so mit den übrigen Teilen des Gerätes verbunden, daß mit ihm in jeder beliebigen Winkelstellung gearbeitet werden kann. Hierzu ist die Klemmleiste4 im Bereich des Handgriffs 1, 2 kugelschalenförmig ausgearbeitet und, von der dem Wischerblatt 8 abgewandten Seite her, parallel zur Rückenprofilleiste 7 aufgeschlitzt. Beim Anziehen der Klemmschraube 5 wird diese Klemmleiste 4 zusammengepreßt, wobei sie die Kugel 2 des Handgriffs 1 in der jeweiligen Stellung fixiert. Das parallel zur Rückenprofilleiste 7 verlaufende Langloch 3 in der Klemmleiste 4 ermöglicht es außerdem, den Handgriff mit der Klemmleiste auf der Rückenprofilleiste seitlich zu verschieben. Die dieses Langloch 3 der Klemmleiste 4 und die Rückenprofilleiste 7 durchdringende Klemmschraube 5 preßt beim Anziehen außerdem die Fixierungskralle 6 gegen das Wischerblatt 8, das auf diese Weise gegen seitliches Verschieben gesichert wird. Dieses Wischerblatt 8 ist zu seiner Abstützung mit seiner dem Anfeuchter 13 zugewandten verdickten Längskante in eine es dort halbkreisförmig umgreifende Halteprofilleiste 9 eingeschoben. Diese Halteprofilleiste 9 lagert zwischen den beiden bogenförmigen Lippen 10, 11 der Rückenprofilleiste 7. Ihre Befestigung erfolgt durch die beiden an ihren freien Enden angebrachten Lappen 12, die die Loppe 11 der Rückenprofilleiste 7 umgreifen. Die Rückenprofilleiste 7 ist zur Aufnahme des Anfeuchters 13 konkav ausgebildet. Dabei ist ihre dem Wischerblatt 8 abgewandte Kante 14 als Tropfenabweiser und zur Unterstützung des Wasserspeichervermögens des Anfeuchters 13 bogenförmig nach vorn gezogen. Den Anfeuchter 13 besteht aus einer Kunststoff-Fellwalze mit Borsten oder Haaren, die hart genug sind, den fettigen Schmutzfilm der Scheibe aufzureißen. Die lösbare Befestigung des auswechselbaren Anfeuchters 13 an der Rückenprofilleiste 7 erfolgt durch ein Klettenband 15, Reißverschlüsse, Druckknöpfe oder andere an sich bekannte Arten. Die beiden Teile 7, 13 können aber auch miteinander verklebt sein.The handle 1 is pivotable on all sides of the ball 2, so connected to the other parts of the device that it can be used in any angular position. For this purpose, the terminal strip 4 in the region of the handle 1, 2 is designed in the shape of a spherical shell and, parallel to the back profile strip 7, is slit open from the side facing away from the wiper blade 8. When the clamping screw 5 is tightened, this clamping strip 4 is pressed together, fixing the ball 2 of the handle 1 in the respective position. The elongated hole 3 running parallel to the back profile strip 7 in the clamping strip 4 also makes it possible to laterally move the handle with the clamping strip on the back profile strip. The clamping screw 5 penetrating this elongated hole 3 of the clamping strip 4 and the back profile strip 7 also presses the fixing claw 6 against the wiper blade 8, which is secured in this way against lateral displacement. This wiper blade 8 is inserted with its thickened longitudinal edge facing the humidifier 13 into a retaining profile strip 9 which surrounds it there in a semicircle. This retaining profile strip 9 is mounted between the two arcuate lips 10, 11 of the back profile strip 7. It is fastened by the two tabs 12 attached at their free ends, which grip around the loop 11 of the back profile strip 7. The back profile bar 7 is concave for receiving the humidifier 13. Her is the wiper blade 8 abge turned edge 14 as a droplet deflector and to support the water storage capacity of the humidifier 13 pulled forward in an arc. The moistener 13 consists of a plastic fur roller with bristles or hair that is hard enough to tear open the greasy film of dirt on the disc. The removable attachment of the replaceable humidifier 13 to the back profile strip 7 is carried out by means of a Velcro strap 15, zippers, push buttons or other types known per se. The two parts 7, 13 can also be glued together.
