Description

Wischblatt. Adapter sowie Werkzeugvorrichtung zum Herstellen eines Adapters  Wiper blade. Adapter and tool device for producing an adapter

Stand der Technik State of the art

Die Erfindung betrifft ein Wischblatt nach dem Oberbegriff des Anspruchs 1 sowie einen Adapter und eine Werkzeugvorrichtung zum Herstellen eines Adapters. Ein Wischblatt nach dem Oberbegriff des Anspruchs 1 ist bereits aus der DE 10 2007 062 304 A1 der Anmelderin bekannt. Bei dem bekannten Wischblatt sind der Wischarm und das Wischblatt mittels eines Adapters miteinander gelenkig verbunden. Hierbei besteht der Adapter aus einem wischarmseitigen Adapterelement und einem wischbiattseitigen Adapterelement, die gelenkig miteinander verbunden sind. Zwischen den beiden Adapterelementen sind flexible Verbindungsstücke zum Zuführen von Waschflüssigkeit vom wischarmseitigen Adapterelement in das wischblattseitige Adapterelement angeordnet. Das wischblatt- seitige Adapterelement leitet die Waschflüssigkeit wiederum über Kanäle in einem Wischblattelement unmittelbar an verschiedenen Stellen vor der Wischlip- pe eines Wischgummi aus. Die beiden Adapterelemente sind jeweils aus Kunststoff gefertigt und einstückig ausgebildet. Dadurch, dass die Adapterelemente jeweils einstückig ausgebildet sind, ist es erforderlich, das Werkzeug, insbesondere in Form eines Spritzgusswerkzeuges, relativ aufwändig zu gestalten, bzw. es sind pro Produktionsschritt nur relativ wenige Adapterelemente mit einem Spritzgusswerkzeug herstellbar. The invention relates to a wiper blade according to the preamble of claim 1 and an adapter and a tool device for producing an adapter. A wiper blade according to the preamble of claim 1 is already known from DE 10 2007 062 304 A1 of the applicant. In the known wiper blade, the wiper arm and the wiper blade are connected to one another in an articulated manner by means of an adapter. Here, the adapter consists of a wischarmseitigen adapter element and a wischbiattseitigen adapter element, which are hinged together. Between the two adapter elements flexible connecting pieces for supplying washing liquid from the wiper arm-side adapter element are arranged in the wiper blade-side adapter element. The wiper blade-side adapter element in turn derives the washing liquid via channels in a wiper blade element directly at various locations in front of the wiper blade of a squeegee. The two adapter elements are each made of plastic and formed in one piece. Characterized in that the adapter elements are each formed in one piece, it is necessary to make the tool, in particular in the form of an injection molding tool, relatively complex, or it can be produced per production step, only a relatively few adapter elements with an injection mold.

Offenbarung der Erfindung Disclosure of the invention

Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Wischblatt nach dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass dieses besonders preiswert bzw. rationell herstellbar ist. Diese Aufgabe wird bei einem Wischblatt mit den Merkmalen des Anspruchs 1 gelöst. Der Erfindung liegt dabei die Idee zugrunde, das wischblattseitige erste Adapterelement wenigstens zweiteilig auszubilden, wobei das erste Adapterelement ein erstes, mit dem wischarmseitigen Adapterelement verbindbares Adapterteil und ein zweites, mit dem Wischarm verbindbares Adapterteil auf- weist. Durch diese Ausgestaltung lassen sich die einzelnen Adapterteile konstruktiv relativ einfach gestalten, sodass die Fertigung, insbesondere auch ein geeignetes Werkzeug zum Herstellen der Adapterteile, relativ einfach ausgebildet sein kann, wodurch ermöglicht wird, pro Prozessschritt mehrere derartige Adapterteile gleichzeitig zu fertigen. Based on the illustrated prior art, the invention has the object, a wiper blade according to the preamble of claim 1 such that this is particularly inexpensive or efficient to produce. This object is achieved in a wiper blade with the features of claim 1. The invention is based on the idea of forming the wiper blade-side first adapter element at least in two parts, the first adapter element having a first adapter part which can be connected to the wiper arm-side adapter element and a second adapter part which can be connected to the wiper arm. As a result of this configuration, the individual adapter parts can be structurally made relatively simple, so that the production, in particular also a suitable tool for producing the adapter parts, can be made relatively simple, which makes it possible to manufacture a plurality of such adapter parts simultaneously per process step.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Wischblatts sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen dabei sämtliche Kombinationen aus zumindest zwei von in den Ansprüchen, der Beschreibung und/oder den Figuren offenbarten Merkmalen. Advantageous developments of the wiper blade according to the invention are specified in the subclaims. All combinations of at least two features disclosed in the claims, the description and / or the figures fall within the scope of the invention.

Besonders bevorzugt ist es, wenn die beiden Adapterteile aus Kunststoff bestehen und als Spritzgussteile ausgebildet sind. Dadurch lässt sich insbesondere eine relativ einfache Verbindung der beiden Adapterteile, z.B. durch Klebe- oder Schweißverbindungen, herstellen. Weiterhin ist das erste Adapterelement da- durch relativ leicht im Gewicht und besitzt gute Korrosionseigenschaften. Zur Vereinfachung des Montageprozesses zwischen den beiden Adapterteilen ist es vorgesehen, dass die beiden Adapterteilen unmittelbar, das heißt ohne zusätzliche Verwendung von separaten Hilfsteilen, miteinander verbunden sind. Besonders bevorzugt ist es dabei, dass die beiden Adapterteile mittels einer formschlüssigen Verbindung bzw. einer Rastverbindung bzw. einer stoffschlüssigen Verbindung miteinander verbunden sind. Durch die Verwendung einer formschlüssigen Verbindungsmethode lassen sich die beiden Adapterteile insbesondere nur auf eine einzige Art und Weise miteinander verbinden, sodass Fehlmontagen ausgeschlossen sind. It is particularly preferred if the two adapter parts are made of plastic and are formed as injection-molded parts. This makes it possible, in particular, to produce a relatively simple connection of the two adapter parts, for example by means of adhesive or welded connections. Furthermore, the first adapter element is relatively light in weight and has good corrosion properties. To simplify the assembly process between the two adapter parts, it is provided that the two adapter parts are connected to one another directly, that is to say without additional use of separate auxiliary parts. It is particularly preferred that the two adapter parts are connected to each other by means of a positive connection or a latching connection or a material connection. By using a positive connection method, the two adapter parts can in particular connect only in a single way with each other, so that incorrect assembly is excluded.

Besonders bevorzugt ist es hierbei, wenn die formschlüssige Verbindung einen Führungssteg am zweiten Adapterteil umfasst, der in eine Ausnehmung des ersten Adapterteils eingreift. Durch den Führungssteg und die Ausnehmung lassen sich insbesondere Kräfte vom Wischblatt auf relativ einfache Art und Weise sicher weiterleiten bzw. übertragen. It is particularly preferred in this case if the positive connection comprises a guide web on the second adapter part, which engages in a recess of the first adapter part. In particular, forces from the wiper blade can be reliably transmitted or transmitted by the guide web and the recess in a relatively simple manner.

Um die Verbindung zwischen den beiden Adapterteilen zusätzlich zu sichern bzw. zu verstärken, damit insbesondere auch besonders hohe Kräfte zwischen den beiden Adapterteilen übertragen zu können, ist es darüber hinaus in einer bevorzugten Ausführung der Erfindung vorgesehen, dass zwischen den beiden Adapterteilen zusätzlich eine stoffschlüssige Verbindung ausgebildet ist. Insbesondere kann es vorgesehen sein, dass die stoffschlüssige Verbindung als Schweißverbindung, insbesondere als Ultraschallschweißverbindung, oder als Klebeverbindung ausgebildet ist. Derartige Verbindungen lassen sich im Großserieneinsatz relativ preiswert durchführen und prozesssicher gestalten. In order to additionally secure or strengthen the connection between the two adapter parts, so that particularly high forces can be transmitted between the two adapter parts, it is also provided in a preferred embodiment of the invention that between the two adapter parts additionally a material connection is trained. In particular, it can be provided that the cohesive connection is designed as a welded connection, in particular as an ultrasonic welding connection, or as an adhesive connection. Such compounds can be carried out in mass production relatively cheap and process reliable.

Um eine gelenkige Verbindung zwischen den beiden Adapterelementen auszubilden, ist es in einer weiteren bevorzugten Ausführungsform der Erfindung vor- gesehen, dass an dem ersten Adapterteil wenigstens ein Lagerzapfen angeformt ist. In einer bevorzugten Ausführungsform ist es dabei vorgesehen, dass der wenigstens eine Lagerzapfen eine Öffnung zum Zuführen einer Waschflüssigkeit zu einem Spritzkanal des Wischblatts aufweist. Somit sind keine zusätzlichen Bauteile bzw. Elemente zur Zuführung der Waschflüssigkeit zum Wischblatt erforderlich, wodurch ein besonders kompakter Aufbau des Wischblatts und eine preisgünstige Herstellbarkeit durch nicht erforderliche zusätzliche Bauteile und Montageschritte ermöglicht werden. In order to form an articulated connection between the two adapter elements, it is provided in a further preferred embodiment of the invention that at least one bearing journal is formed on the first adapter part. In a preferred embodiment, it is provided that the at least one bearing journal has an opening for supplying a washing liquid to an injection channel of the wiper blade. Thus, no additional components or elements for supplying the washing liquid to the wiper blade are required, whereby a particularly compact design of the wiper blade and a low-cost manufacturability are made possible by unnecessary additional components and assembly steps.

In einer ganz besonders bevorzugten Ausführungsform ist es hierbei vorgese- hen, dass an der Umfangsfläche des wenigstens einen Lagerzapfens eine mit einem Waschflüssigkeitsreservoir zumindest mittelbar verbundene Durch- gangsöffnung ausgebildet ist, über die die Waschflüssigkeit in den wenigstens einen Lagerzapfen eingeleitet wird. Dadurch baut der Adapter besonders schmal, da die Zuführung der Waschflüssigkeit nicht über den mittleren Bereich des Adapters erfolgen muss. Weiterhin kann mit einer derartigen Ausgestaltung auf die Ausbildung zusätzlicher Kanäle bzw. Strömungswege für die Waschflüssigkeit im mittleren Bereich des Adapters verzichtet werden, wodurch der Adapter sich einfacher gestalten lässt. Die Erfindung umfasst auch einen Adapter zum wiederlösbaren Befestigen eines Wischblatts an einem Wischarm, wobei der Adapter gemäß der Erfindung ausgebildet ist. In a particularly preferred embodiment, it is provided in this case that on the peripheral surface of the at least one journal a passage opening formed at least indirectly with a washing liquid reservoir is formed, via which the washing liquid is introduced into the at least one journal. As a result, the adapter is built very narrow, since the supply of the washing liquid does not have to be made over the central region of the adapter. Furthermore, with such a configuration, the formation of additional channels or flow paths for the washing liquid in the middle region of the adapter can be dispensed with, as a result of which the adapter can be designed more simply. The invention also includes an adapter for releasably securing a wiper blade to a wiper arm, wherein the adapter is formed according to the invention.

Weiterhin umfasst die Erfindung eine Werkzeugvorrichtung zum Herstellen ei- nes Adapters, wobei die Werkzeugvorrichtung wenigstens ein Spritzgusswerkzeug umfasst, das wenigstens zwei Nester zum Ausbilden wenigstens eines der Adapterteile aufweist. Furthermore, the invention comprises a tool device for producing an adapter, wherein the tool device comprises at least one injection molding tool which has at least two nests for forming at least one of the adapter parts.
