Description

Die Erfindung betrifft einen Epilationsapparat wobei eine treibende und eine getriebene Walze mit Verzahnung versehen sind und ein Walzenpaar bilden, wobei die Walzen eine Drehbewegung ausführen, die im Bereich ihres umfangsseitigen Eingriffes in das Apparateinnere hinein gerichtet ist.The invention relates to an epilation apparatus in which a driving and a driven roller are provided with teeth and form a pair of rollers, the rollers executing a rotary movement which is directed into the interior of the apparatus in the region of their circumferential engagement.

Ein derartiger Epilationsapparat ist in der EP-PA 89201397.0 (PHO 89504) geoffenbart. Bei diesem bekannten Apparat besteht die Gefahr, das Haut zwischen das Walzenpaar gezogen wird, so dass meistens ein Hautschutz verwendet werden muss, z.B. in Form eines Gitters. Kurze Haare können dann aber nicht mehr gegriffen werden.Such an epilation apparatus is disclosed in EP-PA 89201397.0 (PHO 89504). With this known apparatus there is a risk of skin being pulled between the pair of rollers, so that a skin protection must usually be used, e.g. in the form of a grid. Short hair can then no longer be gripped.

Die Erfindung hat sich zum Ziel gesetzt für diese Probleme eine Lösung zu schaffen. Erfindungsgemäss wird dies bei einem Epilationsapparat der eingangs angeführten Gattung dadurch erreicht, dass von jedem Walzenpaar die getriebene Walze rundum verzahnt ist, aber die treibende Walze nur über einem Teil des Umfangs mit Verzahnung versehen ist, so dass die Walzen nur während eines Teiles einer Umdrehung der treibenden Walze miteinander im Eingriff sind.The aim of the invention is to provide a solution to these problems. According to the invention, this is achieved in an epilation apparatus of the type mentioned at the outset in that the driven roller of each pair of rollers is toothed all around, but the driving roller is toothed only over part of the circumference, so that the rollers only during part of a revolution of the driving roller are engaged with each other.

Weitere Merkmale der Erfindung sind in den Unteransprüche erwähnt worden.Further features of the invention have been mentioned in the subclaims.

Die Erfindung wird in folgenden anhand der Zeichnungen, in welchen Ausführungsbeispiele der Erfindung dargestellt sind, näher erläutert.The invention is explained in more detail below with reference to the drawings, in which exemplary embodiments of the invention are shown.

Fig. 1 zeigt in einem Längsschnitt einen Abschnitt eines Epilationsapparates.1 shows a section of an epilation apparatus in a longitudinal section.

Fig. 2 zeigt in vergrössertem Massstab einen Schnitt gemäss der Linie II-II in Fig. 1.FIG. 2 shows, on an enlarged scale, a section along the line II-II in FIG. 1.

Figuren 3 und 4 zeigen in der Darstellungsweise von Fig. 2 Varianten des Walzenpaares.Figures 3 and 4 show in the representation of Fig. 2 variants of the pair of rollers.

Fig. 5 zeigt in ähnlicher Darstellungsweise wie Fig. 1 einen Epilationsapparat, wobei die getriebene Walze auf verschwenkbaren Armen gelagert ist.FIG. 5 shows an epilation apparatus in a representation similar to that of FIG. 1, the driven roller being supported on pivotable arms.

Figuren 6 und 7 zeigen Schnitte gemäss der Linie VI-VI in Fig. 5.Figures 6 and 7 show sections along the line VI-VI in Fig. 5.

In den Figuren 1 und 2 ist mit 1 das Gehäuse eines Epilationsapparates bezeichnet, das eine Gehäuseöffnung 2 aufweist, in deren Bereich eine treibende Walze 3 und eine getriebene Walze 4 angeordnet sind. Die treibende Walze 3 ist nur über einen Teil des Umfangs mit einer Verzahnung 5 versehen, während die getriebene Walze rundum verzahnt ist mit einer Verzahnung 6. Die treibende Walze 3 ist über ein mehrstufiges Zahnradgetriebe 7 von einem Motor 8 antreibbar und die getriebene Walze 4 wird über die Verzahnungen 5 und 6 von der treibenden Walze 3 angetrieben. Die Walzen 3 und 4 führen dabei eine Drehbewegung aus, die im Bereich 9 ihres umfangsseitigen Eingriffes in das Apparateinnere hinein gerichtet ist, siehe Pfeil P. Auf diese Weise ist das Walzenpaar 3, 4 in der Lage ein im Bereich 9 hineinragendes Haar zu ergreifen und auszuziehen. Das entfernte Haar wird dann von den Walzen in den anschliessenden Aufnahmeraum 10 weitertransportiert.In FIGS. 1 and 2, 1 denotes the housing of an epilation apparatus, which has a housing opening 2, in the area of which a driving roller 3 and a driven roller 4 are arranged. The driving roller 3 is provided with a toothing 5 only over part of the circumference, while the driven roller is toothed all around with a toothing 6. The driving roller 3 can be driven by a motor 8 via a multi-stage gear transmission 7 and the driven roller 4 becomes driven by the driving roller 3 via the toothings 5 and 6. The rollers 3 and 4 perform a rotary movement which is directed in the area 9 of their circumferential engagement into the interior of the apparatus, see arrow P. In this way, the pair of rollers 3, 4 is able to grasp and protrude hair in the area 9 to take off. The removed hair is then transported further by the rollers into the subsequent receiving space 10.

Die Verzahnung 5 der treibenden Walze 3 besteht nur aus einem Zahn, so dass die Walzen 3, 4 nur während eines Teiles einer Umdrehung der treibenden Walze 3 miteinander in Eingriff sind. Wenn die Verzahnungen 5 und 6 ausser Eingriff sind bleibt die getriebene Walze 4 stehen, z.B. durch die Reibung in den Lagern 11, 12 der Achse 13 dieser Walze oder durch Berührung der Walze 4 mit der Haut. Dadurch verringern sich erheblich die Chancen dass die Haut zwischen die Walzen 3, 4 gerät und verletzt wird.The toothing 5 of the driving roller 3 consists of only one tooth, so that the rollers 3, 4 are in engagement with one another only during part of a revolution of the driving roller 3. When the teeth 5 and 6 are disengaged, the driven roller 4 stops, e.g. by the friction in the bearings 11, 12 of the axis 13 of this roller or by contact of the roller 4 with the skin. This considerably reduces the chances of the skin getting between the rollers 3, 4 and being injured.

Auch der Energiebedarf des Apparates wird dadurch niedriger was insbesondere wenn das Apparat mit einer Batterie als Stromquelle versehen ist, von Bedeutung ist.This also lowers the energy requirement of the apparatus, which is particularly important if the apparatus is provided with a battery as a power source.

Ist ein haar von den Verzahnungen 5, 6 ergriffen worden, so wird auch die naheliegende Haut einigermassen in die Richtung P mitgezogen. Weil die treibende Walze 3 nur einen Zahn 5 besitzt besteht nicht die Gefahr dass diese Hautpartie durch einen folgenden Zahn der Walze 3 und die Verzahnung 6 der Walze 4 gegriffen wird. Auch hierdurch ist also die Gefahr der Hautverletzung weitgehend beseitigt.If a hair has been gripped by the teeth 5, 6, the nearby skin is also pulled somewhat in the P direction. Because the driving roller 3 has only one tooth 5, there is no risk that this skin area is gripped by a following tooth of the roller 3 and the toothing 6 of the roller 4. This also largely eliminates the risk of skin injury.

Es ist auch möglich, dass die treibende Walze 3 mehrere Zähne 14 aufweist (Fig. 3), die z.B. regelmässig über dem Umfang dieser Walze verteilt sein können.It is also possible for the driving roller 3 to have a plurality of teeth 14 (FIG. 3), which e.g. can be distributed regularly over the circumference of this roller.

Die treibende Walze 3 kan mehrere Zähne 15 aufweisen, die in einer Gruppe am Umfang der Walze angeordnet sind oder die in Gruppen über den Umfang der Walze 3 verteilt sind (Fig. 4).The driving roller 3 can have a plurality of teeth 15 which are arranged in a group on the circumference of the roller or which in Groups are distributed over the circumference of the roller 3 (Fig. 4).

Die Zähne können geradlinig oder Schraubenlinienartig in axialer Richtung der Walzen 3, 4 verlaufen und im Querschnitt ein evolventes oder anderes Profil haben.The teeth can run in a straight line or like a helix in the axial direction of the rollers 3, 4 and have an involute or other profile in cross section.

In der Ausführungsform nach den Figuren 5-7 ist die getriebene Walze 4 auf verschwenkbaren Armen 16, gelagert. Mit diesen verschwenkbaren Armen wirkt je eine Blattfeder 17 zusammen, unter deren Wirkung die getriebene Walze 4 in Richtung der treibenden Walze 3 angedrückt wird. Auf diese Weise wird ein einwandfreies umfangsseitiges Zusammenwirken der Walzen 3 und 4 erreicht, wodurch die zu entfernenden Haare sicher von den Walzen erfasst und zwischen diesen eingeklemmt und entfernt werden.In the embodiment according to FIGS. 5-7, the driven roller 4 is mounted on pivotable arms 16. A leaf spring 17 interacts with these pivotable arms, under the action of which the driven roller 4 is pressed in the direction of the driving roller 3. In this way, a perfect circumferential interaction of the rollers 3 and 4 is achieved, whereby the hair to be removed is securely gripped by the rollers and clamped and removed between them.

Sind die Verzahnungen 5, 6 ausser Eingriff dann ist der Achsabstand A (Fig. 6) zwischen den Walzen 3 und 4 minimal, so dass der Raum zwischen den Walzen im Bereich 9 (wie in Fig. 2 angedeutet) minimal ist. Die Gefahr, dass die Haut 18 zwischen die Walzen gerät und geklemmt wird ist deshalb gering. Ein Haar 19 kann sehr nahe an der haut gefasst werden, so dass auch kurze Haare ausgezogen werden können.If the toothings 5, 6 are disengaged, the center distance A (FIG. 6) between the rollers 3 and 4 is minimal, so that the space between the rollers in the region 9 (as indicated in FIG. 2) is minimal. The risk that the skin 18 gets between the rollers and is pinched is therefore low. A hair 19 can be gripped very close to the skin, so that short hair can also be pulled out.

Bei dieser Ausführungsform nimmt der Achsabstand zu wenn die Verzahnungen 5 und 6 miteinander im Eingriff sind.In this embodiment, the center distance increases when the toothings 5 and 6 are in engagement with one another.

Gelangt das Haar 19 zwischen die Walzen 3 und 4 (Fig. 7), dann erweitert sich also der Achsabstand auf B, wodurch eine vergrösserte Klemmkraft auf das Haar ausgeübt wird.If the hair 19 gets between the rollers 3 and 4 (FIG. 7), then the center distance widens to B, as a result of which an increased clamping force is exerted on the hair.
