Description

Die Erfindung betrifft einen Lüfter, insbesondere einen Tischfächer, der von einem Tragring gehalten ist, der beispielsweise in einer Gabel auf einem Sockel schwenkbar angeordnet ist. Bisher war gewöhnlich bei einem solchen Lüfter der Lüftermotor mit dem Flügelrad innerhalb dieses Tragringes durch eine besondere Konstruktion gehalten. Außerdem war das Flügelrad des Lüfters durch einen Schutzkorb gesichert. Man hat auch schon den Lüfter so ausgebildet, daß der Lüftermotor von dem Schutzkorb gehalten ist, der einen das Flügelrad umgebenden Tragring besitzt. Bei dieser bekannten Ausführung hat der Schutzkorb einen inneren Tragring, der den Motor umgibt und auf ihm wie eine Bandage mittels eines Schraubenbolzens befestigt ist. Diese Befestigungsart des Motors erfordert eine besonders sorgfältige und daher kostspielige Montagearbeit, damit der Motor und damit der Lüfter den richtigen Sitz in dem Schutzkorb erhält. Die vorliegende Erfindung zeigt eine verbesserte Ausführung der Befestigung des Motorlüfters.The invention relates to a fan, in particular a table fan, which is held by a support ring, for example in a fork on a Base is pivotably arranged. Until now it was common with such a fan the fan motor with the impeller inside this support ring by a special one Construction held. In addition, the fan impeller was protected by a protective cage secured. The fan has already been designed in such a way that the fan motor from the protective cage is held, which has a support ring surrounding the impeller. In this known version, the protective cage has an inner support ring that the Engine surrounds and is attached to it like a bandage by means of a screw bolt is. This type of mounting of the engine requires particularly careful and therefore costly assembly work so that the motor and therefore the fan are correctly seated received in the protective cage. The present invention is an improved embodiment the fastening of the motor fan.

Erfindungsgemäß weist der zweckmäßig aus Draht gebildete Schutzkorb einen offenen, federnden Innenring auf, der in eine Nut des Motorgehäuses eingesprengt ist. Hierdurch wird der Vorteil erreicht, daß sich der Motorlüfter ohne Werkzeuge schnell und mühelos an dem ihn tragenden Schutzkorb anbringen läßt, wobei der Motor in axialer Richtung stets den richtigen Sitz in dem Schutzkorb hat und zwangläufig die genaue symmetrische Lage des Lüfterflügels gegenüber dem ihm umgebenden Schutzkorb erreicht wird.According to the invention, the protective cage, which is expediently made of wire, has an open, resilient inner ring which is forced into a groove in the motor housing is. This has the advantage that the motor fan can be operated without tools can be attached quickly and easily to the protective cage carrying it, with the motor always has the correct seat in the protective cage in the axial direction and inevitably the exact symmetrical position of the fan blade in relation to the protective cage surrounding it is achieved.

Die äußeren Enden des Schutzkorbes können dabei in an sich bekannter Weise in den Tragring eingesprengt -sein, so daß auch für diese Befestigung keine Schrauben oder sonstigen Befestigungsmittel erforderlich sind.The outer ends of the protective cage can be known per se Way into the support ring -being, so that none for this attachment Screws or other fasteners are required.

In den Fig. i und 2 ist die Erfindung an einem Ausführungsbeispiel dargestellt. Der aus dem Antriebsmotor i und dem Flügelrad 2 bestehende Lüfter ist innerhalb eines felgenartigen Tragringes 3 angeordnet. Der Tragring ist mit einem vorderen und einem hinteren Schutzkorb 4 und versehen, der aus Draht gebildet ist. Der hintere Schutzkorb weist einen Innenring 6 auf, der in eine Nut 7 des Motors i eingesprengt und hiermit an diesem schraubenlos befestigt ist. Die äußeren Enden 8 des Schutzkorbes sind ebenfalls sprengringartig in dem felgenartigen Tragring 3 eingesprengt und werden lediglich dadurch gehalten.In FIGS. I and 2, the invention is based on an exemplary embodiment shown. The fan consisting of the drive motor i and the impeller 2 is arranged within a rim-like support ring 3. The support ring is with a front and a rear protective cage 4 and provided, which is formed from wire. The rear protective cage has an inner ring 6 which is inserted into a groove 7 of the motor i collapsed and is hereby attached to this screwlessly. The outer ends 8 of the protective cage are also like a snap ring in the rim-like support ring 3 and are only held by it.

Der Tragring 3 ist schwenkbar in einer Gabel 9 gelagert, die auf einem Sockel io befestigt ist.The support ring 3 is pivotably mounted in a fork 9 on a Base io is attached.
