Description

Die Erfindung betrifft ein Flügelrad für Tischfächer, Wandfächer od. dgl.The invention relates to an impeller for table compartments, wall compartments od. like

Es sind bereits Flügelräder für Tischfächer. Wandfächer od. dgl. bekannt, deren Flügel aus elastischem Werkstoff, beispielsweise aus Gummi bestehen. Diese haben den Nachteil, daß sie entweder zu schwer sind oder eine zu geringe Steifigkeit haben, so daß ihr Wirkungsgrad verhältnismäßig schlecht ist.There are already impellers for table compartments. Wall compartments or the like known, the wings of which are made of elastic material, for example made of rubber. These have the disadvantage that they are either too heavy or have too little rigidity have, so that their efficiency is relatively poor.

Gemäß der Erfindung werden Flügelräder der vorerwähnten Art dadurch verbessert, daß man in den Flügeln Hohlräume vorsieht, die zur Erhöhung ihrer Steifigkeit mit Preßluft od. dgl. angefüllt sind. Auf diese ZVeise ist es möglich, mit einem geringen Aufwand an Werkstoff Flügelräder auszubilden, deren Flügel eine allen Anforderungen der Praxis genügende Steifigkeit aufweisen.According to the invention, impellers of the aforementioned type are thereby improved that one provides cavities in the wings to increase their rigidity with compressed air or the like. Are filled. In this way it is possible to use a Little effort to train material impellers, the wings of which meet all requirements have sufficient rigidity in practice.

Die Zeichnung zeigt als Ausführungsbeispiel in der Fig. i in Ansicht und in der Fig. 2 im Querschnitt nach der Linie II-II der Fig. r einen Gummiflügel i mit Zwischenwänden 2, zwischen denen sich Hohlräume 3 befinden. Diese Hohlräume 3 sind mit Preßluft od. dgl. angefüllt, so daß sich der Flügel strafft.The drawing shows an exemplary embodiment in FIG and in Fig. 2 in cross section along the line II-II of Fig. r a rubber wing i with partition walls 2, between which cavities 3 are located. These cavities 3 are filled with compressed air or the like, so that the wing tightens.
