Description

Die Erfindung betrifft ein Epilationsgerät mit einem zur Rotation um seine Achse antreibbaren Drehzylinder, an dessen Umfang in Umfangsrichtung versetzt angeordnete Klemmvorrichtungen zum Einklemmen und Auszupfen von Haaren vorgesehen sind.The invention relates to an epilation device with a rotatable about its axis rotary cylinder, on the circumference circumferentially offset arranged clamping devices are provided for clamping and plucking hair.

Derartige Epilationsgeräte bzw. Drehzylinder für Epilationsgeräte sind aus dem Stand der Technik, wie beispielsweise der WO 98/05234 oder der US 5,196,021, bekannt geworden. Dabei sind meist mehrere Klemmvorrichtungen über den Umfang des Drehzylinders verteilt angeordnet, wobei die Anordnung der Klemmvorrichtungen zumeist in mehreren Reihen parallel zur Drehachse des Drehzylinders erfolgt, sodass alle Klemmvorrichtungen einer Reihe gleichzeitig eine Zupfzone durchlaufen. Die in einer Reihe angeordneten Klemmvorrichtungen werden hierbei gemeinsam und gleichzeitig betätigt und bilden somit einen linienförmigen Zupfbereich auf der Haut des Benutzers.Such epilators or rotary cylinders for epilators have become known from the prior art, such as WO 98/05234 or US 5,196,021. In this case, a plurality of clamping devices are usually distributed over the circumference of the rotary cylinder, wherein the arrangement of the clamping devices takes place mostly in several rows parallel to the axis of rotation of the rotary cylinder, so that all clamping devices of a row go through a plucking zone at the same time. The clamping devices arranged in a row are hereby actuated jointly and simultaneously and thus form a line-shaped plucking area on the skin of the user.

Bei dem Epilationsgerät gemäß der US 5,196,021 besteht der Drehzylinder aus einer Mehrzahl von Scheiben, welche radial nach außen vorstehende Klemmelemente aufweisen, wobei jeweils zwei Klemmelemente zweier benachbarter Scheiben zueinander bewegbar sind und eine Klemmvorrichtung bilden. Zur Betätigung der Klemmvorrichtungen weisen die einzelnen Klemmelemente in axialer Richtung des Drehzylinders verlaufende Fortsätze auf, welche bei Rotation des Drehzylinders an stirnseitigen Druckrollen vorbeigeführt werden, sodass in einer Zupfzone des Gerätes jeweils zwei Klemmelemente durch eine beidseitige Betätigung aufeinander zu bewegt und in Klemmkontakt miteinander gebracht werden. Die Klemmelemente aller den Drehzylinder bildenden Scheiben sind dabei so zueinander angeordnet, dass sich jeweils nur ein Paar Klemmelemente in einer Zupfzone des Epilationsgerätes befindet.In the epilator according to US 5,196,021, the rotary cylinder consists of a plurality of discs having radially outwardly projecting clamping elements, wherein each two clamping elements of two adjacent discs are mutually movable and form a clamping device. To actuate the clamping devices, the individual clamping elements in the axial direction of the rotary cylinder extending extensions, which are guided past rotation of the rotary cylinder on front side pressure rollers so that in a plucking zone of the device two clamping elements each moved by a two-sided operation towards each other and brought into clamping contact with each other , The clamping elements of all the rotating cylinders forming discs are arranged to each other so that only one pair of clamping elements is in a plucking zone of the epilating device.

Bei diesen bekannten Epilationsgeräten werden die Klemmvorrichtungen somit immer derart betätigt, dass sich ein punktförmiger und bestenfalls ein sich in Richtung der Drehachse des Drehzylinders erstreckender linienförmiger Zupfbereich auf der Haut des Benutzers ergibt. Die Effizienz der Epilation wird dadurch jedoch wesentlich verringert, da ein sicheres und effizientes Erfassen der auszuzupfenden Körperhaare nur dann gewährleistet ist, wenn das Epilationsgerät vom Benutzer in einem vorbestimmten Winkel zur Hautoberfläche gehalten wird und die Klemmvorrichtungen genau dann betätigt werden, wenn die Klemmvorrichtungen in Berührung mit der Haut des Benutzers gelangen. In der Praxis hat sich jedoch gezeigt, dass das Einhalten einer vorbestimmten, stets gleich bleibenden Ausrichtung des Epilationsgerätes relativ zur Haut nahezu unmöglich ist, sodass es sich nicht vermeiden lässt, dass der Drehzylinder mit einem Bereich auf die Haut aufgelegt wird, in welchem die Klemmvorrichtungen noch nicht, nur unvollständig oder nicht mehr geschlossen und daher unwirksam sind. Die vorliegende Erfindung zielt daher darauf ab, ein Epilationsgerät zu schaffen, welches eine effiziente Epilation auch dann gewährleistet, wenn das Epilationsgerät entsprechend dem natürlichen Bewegungsablauf während der Benützung unter wechselnden Winkeln relativ zur Haut gehalten wird.In these known epilating devices, the clamping devices are thus always operated in such a way that a punctiform and at best a point in the direction of the axis of rotation of the rotary cylinder extending linear plucking area on the skin of the user results. However, the efficiency of the epilation is thereby substantially reduced because a secure and efficient detection of the body hair to be spewed is ensured only if the epilator is held by the user at a predetermined angle to the skin surface and the clamping devices are operated precisely when the clamping devices in contact with the skin of the user. In practice, however, it has been shown that maintaining a predetermined, always consistent alignment of the epilator relative to the skin is almost impossible, so that it can not be avoided that the rotary cylinder is placed with an area on the skin, in which the clamping devices not yet, only incomplete or no longer closed and therefore ineffective. The present invention therefore aims to provide an epilation device, which ensures efficient epilation even if the epilation device is held in accordance with the natural movement during use at changing angles relative to the skin.

Zu diesem Zweck ist das Epilationsgerät der eingangs genannten Art erfindungsgemäß im wesentlichen dadurch gekennzeichnet, dass die Betätigungsmittel für die Klemmvorrichtungen derart ausgebildet und angeordnet sind, dass jeweils wenigstens zwei in Umfangsrichtung versetzte Klemmvorrichtungen gleichzeitig betätigt werden. Dadurch, dass nun im Unterschied zu den bekannten Epilationsgeräten die Klemmvorrichtungen nicht entlang eines in Richtung der Achse des Drehzylinders verlaufenden linienförmigen Zupfbereiches betätigt werden, sondern die Betätigung derart erfolgt, dass jeweils wenigstens zwei in Umfangsrichtung versetzte Klemmvorrichtungen gleichzeitig betätigt werden, ergibt sich eine wirksame Zupfzone, welche sich in Umfangsrichtung des Drehzylinders gesehen über einen vergrößerten Bereich erstreckt. Dabei gelangt in Abhängigkeit von dem jeweils vom Benutzer gewählten Winkel des Epilationsgerätes relativ zur Haut wenigstens eines der wenigstens zwei Klemmvorrichtungen effizient zum Einsatz. Da sich wenigstens zwei Klemmvorrichtungen, welche gleichzeitig betätigt werden, nun nicht auf einer gemeinsamen achsparallelen Linie bzw. Erzeugenden des Drehzylinders befinden, wird der relative Abstand der gleichzeitig betätigten Klemmeinrichtungen entsprechend vergrößert, wodurch subjektiv eine Verringerung unangenehmer Empfindungen beobachtet werden kann.For this purpose, the epilation device of the aforementioned type according to the invention is essentially characterized in that the actuating means for the clamping devices are designed and arranged such that in each case at least two circumferentially offset clamping devices are actuated simultaneously. Due to the fact that, in contrast to the known epilating devices, the clamping devices are not actuated along a linear plucking area extending in the direction of the axis of the rotary cylinder, but the actuation takes place in such a way that at least two circumferentially offset clamping devices are actuated simultaneously, an effective plucking zone results , which extends in the circumferential direction of the rotary cylinder over an enlarged area. In this case, depending on the particular angle of the epilator selected by the user, at least one of the at least two clamping devices arrives relative to the skin efficient use. Since at least two clamping devices, which are actuated simultaneously, are now not located on a common axis-parallel line or generatrix of the rotary cylinder, the relative distance between the simultaneously actuated clamping devices is correspondingly increased, whereby subjectively a reduction of unpleasant sensations can be observed.

Gemäß einer bevorzugten Ausbildung beträgt der Versatz der gleichzeitig betätigten Klemmvorrichtungen zwischen 3° und 45°, vorzugsweise 32°. Selbstverständlich ist auch ein größerer Versatz in Umfangsrichtung denkbar. Durch den bevorzugt angegebenen Winkel ergibt sich eine Zupfzone, welche sich über einen Zentriwinkel von etwa 50° über den Umfang des Drehzylinders erstreckt, sodass das Auszupfen der Haare erleichtert wird. Das Ausmaß des Versatzes kann hierbei derart gewählt werden, dass sich in Achsrichtung des Drehzylinders eine Überlappung der gleichzeitig betätigten Klemmvorrichtungen ergibt oder dass die gleichzeitig betätigten Klemmvorrichtungen in Umfangsrichtung unmittelbar aneinander anschließen.According to a preferred embodiment, the offset of the simultaneously actuated clamping devices is between 3 ° and 45 °, preferably 32 °. Of course, a larger offset in the circumferential direction is conceivable. The preferred angle given results in a plucking zone which extends over a central angle of about 50 ° over the circumference of the rotary cylinder, so that the plucking of the hair is facilitated. The extent of the offset can in this case be selected such that in the axial direction of the rotary cylinder results in an overlap of the simultaneously operated clamping devices or that the simultaneously operated clamping devices in the circumferential direction directly adjoin one another.

Bei dem erfindungsgemäßen Epilationsgerät müssen somit während der Rotation des Drehzylinders jeweils die die Zupfzone durchlaufenden, wenigstens zwei in Umfangsrichtung versetzten Klemmvorrichtungen gleichzeitig betätigt werden. Hierzu ist es vorteilhaft, dass die einzelnen Klemmvorrichtungen einzeln und gesondert voneinander betätigbar sind, wobei naturgemäß dies zur Folge hat, dass der konstruktive Aufwand erhöht wird, wenn eine Vielzahl von Klemmvorrichtungen entlang des Umfanges des Drehzylinders angeordnet werden soll. Um nun dennoch eine einfachere Konstruktion zu erreichen ist die Ausbildung bevorzugt derart weitergebildet, dass die jeweils wenigstens zwei in Umfangsrichtung versetzten, gleichzeitig betätigten Klemmvorrichtungen in Achsrichtung versetzt angeordnet sind. Bei dieser Ausbildung sind die gleichzeitig betätigten Klemmvorrichtungen somit entlang einer zur Achse des Drehzylinders geneigt verlaufenden Linie angeordnet. Dadurch wird die Möglichkeit geschaffen den gemeinsam betätigten Klemmvorrichtungen gemeinsame Bauteile beispielsweise für die Führung, die Lagerung, die Betätigung und die Rückstellung der Klemmvorrichtungen zuzuordnen und es kann in diesem Zusammenhang die Ausbildung beispielsweise derart getroffen sein, dass den beweglichen Klemmelementen der jeweils gleichzeitig betätigten Klemmvorrichtungen ein gemeinsames Federelement zugeordnet ist, gegen dessen Kraft die Klemmelemente jeweils verschiebbar sind.In the case of the epilation appliance according to the invention, in each case, during the rotation of the rotary cylinder, in each case the clamping devices passing through the plucking zone, at least two clamping devices offset in the circumferential direction, must be actuated simultaneously. For this purpose, it is advantageous that the individual clamping devices are individually and separately operable from each other, which naturally has the consequence that the design effort is increased when a plurality of clamping devices along the circumference of the rotary cylinder to be arranged. In order nevertheless to achieve a simpler construction, the design is preferably developed in such a way that the respectively offset at least two circumferentially offset, simultaneously actuated clamping devices are arranged offset in the axial direction. In this embodiment, the simultaneously operated clamping devices are thus arranged along a line inclined to the axis of the rotary cylinder. This will be the Possibility created the jointly actuated clamping devices common components, for example, for the leadership, the storage, the operation and the provision of the clamping devices assigned and it may be made in this context, the training, for example, that the movable clamping elements of each simultaneously actuated clamping devices associated with a common spring element is, against the force of the clamping elements are each displaced.

Eine weitere Vereinfachung ergibt sich dadurch, dass, wie es einer bevorzugten Weiterbildung entspricht, die Klemmvorrichtungen jeweils von einem relativ zum Drehzylinder feststehenden Klemmelement und einem beweglichen, gegen das feststehende Klemmelement anpressbaren Klemmelement gebildet sind. Dabei muss somit lediglich ein Klemmelement betätigt werden, sodass der Betätigungsmechanismus wesentlich einfacher gestaltet werden kann. Die feststehenden Klemmelemente können hierbei jeweils von einer Seitenwand einer im Drehzylinder vorgesehenen Durchbrechung gebildet sein, in welche je ein bewegliches Klemmelement eintaucht. Dadurch wird eine optimale Integration der Klemmevorrichtungen in dem Drehzylinder und somit eine besonders hautschonende Epilation gewährleistet, wobei lediglich darauf zu achten ist, dass die beweglichen Klemmelemente nicht aus den Durchbrechungen des Drehzylinders über den Außenmantel des Drehzylinders hervorragen. Dadurch werden Irritationen der Haut durch scharfkantige Klemmelemente vermieden.A further simplification results from the fact that, as it corresponds to a preferred development, the clamping devices are each formed by a relative to the rotary cylinder fixed clamping element and a movable, can be pressed against the fixed clamping element clamping element. In this case, therefore, only one clamping element must be actuated, so that the actuating mechanism can be made much simpler. The fixed clamping elements can in each case be formed by a side wall of an opening provided in the rotary cylinder, in each of which a movable clamping element dips. As a result, an optimal integration of the clamping devices in the rotary cylinder and thus ensures a particularly skin-friendly epilation, only care must be taken that the movable clamping elements do not protrude from the openings of the rotary cylinder on the outer surface of the rotary cylinder. As a result, irritations of the skin are avoided by sharp-edged clamping elements.

Zur gesonderten Betätigung der einzelnen Klemmvorrichtungen umfassen die Betätigungsmittel in bevorzugter Weise sich in Achsrichtung des Drehzylinders erstreckende Koppelglieder, welche mit den Klemmvorrichtungen zusammenwirken. Die sich in Achsrichtung des Drehzylinders erstreckenden Koppelglieder dienen hierbei der Weitergabe des Betätigungshubes von der Stirnseite des Drehzylinders an die einzelnen Klemmvorrichtungen, wobei jeder Klemmvorrichtung ein gesondertes Koppelglied zugeordnet ist, um eine gesonderte Betätigung aller Klemmvorrichtungen zu erreichen. Bevorzugt ist die Ausbildung hierbei derart weitergebildet, dass die Koppelglieder als in axialer Richtung des Drehzylinders bewegbar geführte Schlitten ausgebildet sind, wobei die beweglichen Klemmelemente winkelsteif mit jeweils einem Schlitten gekoppelt sind. Bei dieser Ausbildung wird der Betätigungshub durch die winkelsteife Verbindung der Klemmelemente mit dem Koppelglied unmittelbar an die Klemmelemente weitergegeben, sodass sich eine besonders vorteilhafte und direkte Kraftübertragung ergibt. Die beweglichen Klemmelemente werden hierbei stets parallel zum feststehenden Klemmelement geführt, wobei ein linienförmiger Kontakt zwischen den beiden Klemmelementen einer Klemmvorrichtung erreicht wird. Dadurch können die auszuzupfenden Haare besonders fest eingeklemmt und zuverlässig ausgezupft werden, wobei auch Schwenkbewegungen und Verklemmungen bzw. Verkantungen der einzelnen Klemmelemente vermieden werden können.For separate operation of the individual clamping devices, the actuating means preferably comprise coupling members extending in the axial direction of the rotary cylinder, which interact with the clamping devices. The extending in the axial direction of the rotary coupling members serve in this case the passing of the actuating stroke of the end face of the rotary cylinder to the individual clamping devices, each clamping device is assigned a separate coupling member to a separate operation of all To achieve clamping devices. Preferably, the training is further developed in such a way that the coupling members are designed as in the axial direction of the rotary cylinder movably guided slide, wherein the movable clamping elements are angularly rigid, each coupled to a carriage. In this embodiment, the actuating stroke is passed through the angle rigid connection of the clamping elements with the coupling member directly to the clamping elements, resulting in a particularly advantageous and direct power transmission. The movable clamping elements are always guided parallel to the fixed clamping element, wherein a linear contact between the two clamping elements of a clamping device is achieved. As a result, the hair to be dispensed can be clamped particularly firmly and plucked reliably, whereby pivotal movements and jamming or tilting of the individual clamping elements can be avoided.

Die Schlitten können an jeweils zwei sich in Achsrichtung erstreckenden Lagerstangen gleitend gelagert sein, wobei in Umfangsrichtung benachbarte Betätigungselemente höchstens eine gemeinsame Lagerstange aufweisen. Durch die Verwendung von durchgehenden Lagerstangen, wird die Gefahr von Verkantungen durch außenmittige Belastungen vermieden. Weiters wird dadurch die Möglichkeit geschaffen mehrere Schlitten an denselben zwei durchgehenden Lagerstangen zu führen, sodass die Anzahl der Bauteile weiter verringert werden kann. Dabei können die Schlitten der jeweils gleichzeitig betätigten Klemmvorrichtungen auf zwei gemeinsamen Lagerstangen geführt sein, wobei zwischen diesen Schlitten ein in axialer Richtung wirksames Federelement angeordnet ist, und wobei weiters wenigstens einer dieser Schlitten einen in Drehrichtung des Drehzylinders versetzten Bereich und wenigstens ein anderer dieser Schlitten einen entgegen der Drehrichtung des Drehzylinders versetzten Bereich aufweist, mit welchen versetzten Bereichen jeweils das bewegliche Klemmelement gekoppelt bzw. verbunden ist. Durch diese Konstruktion wird erreicht, dass die gemeinsam betätigten Klemmvorrichtungen auf einer gemeinsamen axialen Führung gelagert werden und dennoch in Umfangsrichtung versetzt angeordnet werden können.The carriages may be slidably mounted on each of two bearing rods extending in the axial direction, with adjacent actuating elements having at most one common bearing rod in the circumferential direction. Through the use of continuous bearing rods, the risk of tilting by external loads is avoided. Furthermore, this creates the opportunity to run several carriages on the same two continuous bearing rods, so that the number of components can be further reduced. In this case, the carriages of the respectively simultaneously actuated clamping devices can be guided on two common bearing rods, wherein between these carriages an axially effective spring element is arranged, and further wherein at least one of these carriages an offset in the rotational direction of the rotary cylinder area and at least one other of these carriages Has offset offset from the direction of rotation of the rotary cylinder area, with which offset areas in each case the movable clamping element is coupled or connected. By this construction it is achieved that the jointly actuated clamping devices on a common axial guide be stored and yet offset in the circumferential direction can be arranged.

Zur Ansteuerung und Betätigung der einzelnen Klemmvorrichtungen müssen geeignete Steuerungselemente vorgesehen sein und es ist die Ausbildung mit Vorteil derart ausgebildet, dass die Betätigungsmittel an den Stirnseiten des Drehzylinders angeordnete Steuerungselemente umfassen, welche zur Betätigung der Klemmvorrichtung mit den Koppelgliedern zusammenwirken. Bevorzugt ist die Ausbildung hierbei derart getroffen, dass an jeder Stirnseite des Drehzylinders eine Druckrolle angeordnet ist, auf welche die Koppelglieder auflaufen, wobei die eine Druckrolle relativ zur gegenüberliegenden Druckrolle in Umfangsrichtung des Drehzylinders versetzt angeordnet ist, wobei durch die versetzte Anordnung der Druckrollen, welche den Betätigungshub auslösen, erreicht wird, dass in Umfangsrichtung versetzt angeordnete Klemmevorrichtungen gleichzeitig betätigt werden. Dasselbe Ergebnis kann naturgemäß auch umgekehrt dadurch erreicht werden, dass beispielsweise die Kontaktflächen der Koppelglieder, welche mit den Druckrollen zusammenwirken, in Umfangsrichtung des Drehzylinders versetzt angeordnet sind, wobei in diesem Fall ein Versatz der Druckrollen selbst nicht erforderlich ist. Ausgehend von der zuerst genannten Alternative, bei welcher die Druckrollen in Umfangsrichtung versetzt angeordnet sind, bestimmt das Ausmaß des Versatzes der Druckrollen den wirksamen Zupfbereich des Epilationsgerätes und es ist in diesem Zusammenhang die Ausbildung mit Vorteil derart ausgebildet, dass der Versatz der Druckrollen < 60°, vorzugsweise 32° beträgt.To control and operate the individual clamping devices suitable control elements must be provided and it is the training advantageously designed such that the actuating means comprise arranged on the end faces of the rotary cylinder control elements which cooperate for actuating the clamping device with the coupling members. Preferably, the training is in this case made such that on each end side of the rotary cylinder, a pressure roller is arranged, which accumulate on the coupling members, wherein a pressure roller is arranged offset relative to the opposite pressure roller in the circumferential direction of the rotary cylinder, wherein by the staggered arrangement of the pressure rollers trigger the actuating stroke, it is achieved that offset in the circumferential direction arranged clamping devices are operated simultaneously. The same result can of course be achieved conversely by, for example, that the contact surfaces of the coupling members, which cooperate with the pressure rollers, are arranged offset in the circumferential direction of the rotary cylinder, in which case an offset of the pressure rollers themselves is not required. Starting from the first-mentioned alternative, in which the pressure rollers are arranged offset in the circumferential direction, the extent of the offset of the pressure rollers determines the effective plucking range of the epilator and it is in this context the training advantageously designed such that the offset of the pressure rollers <60 ° , preferably 32 °.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. In dieser zeigt Fig.1 eine perspektivische Ansicht eines Drehzylinders eines Epilationsgerätes, Fig.2 eine perspektivische Ansicht des Zupfzylinders ohne Zylindermantel, Fig.3 eine Teilansicht von Fig.2 und Fig.4 eine schematische Abwicklung des Drehzylinders.The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. 1 shows a perspective view of a rotary cylinder of an epilation apparatus, FIG. 2 shows a perspective view of the plucking cylinder without cylinder jacket, FIG. 3 shows a partial view of FIG. 2 and FIG. 4 shows a schematic development of the rotary cylinder.

In Fig.1 ist ein Drehzylinder 1 ersichtlich, welcher um eine Achse 2 rotierbar gelagert ist. Der Antrieb des Zylinders 1 erfolgt über ein an einer Stirnseite des Zylinders 1 angeordnetes Ritzel 3, welches mit einer nicht näher dargestellten Antriebseinheit zusammenwirkt. Im Mantel 4 des Zylinders sind Durchbrechungen 5 vorgesehen, in welche von Winkelblechen 6 gebildete Klemmelemente eintauchen. Die Klemmelemente 6 sind beweglich angeordnet und bilden gemeinsam mit den Seitenwänden der Durchbrechungen 5 jeweils Klemmvorrichtungen 7. Die beweglichen Klemmelemente 6 sind starr mit Schlitten 8 verbunden, welche sich in Richtung der Achse 2 erstrecken. Dabei ist jeder Schlitten 8 mit einem einzigen Klemmblech 6 verbunden, sodass jede Klemmvorrichtung durch Verschiebung des Schlittens 8 entsprechend dem Doppelpfeil 9 gesondert betätigt werden kann. Jeder Schlitten 8 ist hierbei auf jeweils zwei der über den Umfang gleichmäßig verteilten Lagerstangen 10 geführt. Die Betätigung der Schlitten 8 erfolgt über eine an jeder Stirnseite des Zylinders 1 angeordnete Druckrolle, auf welche die Schlitten 8 mit ihren Stirnflächen 11 auflaufen, sodass sich eine Verschiebung der Schlitten 8 ergibt.In Figure 1, a rotary cylinder 1 can be seen, which is mounted rotatably about an axis 2. The drive of the cylinder 1 via a arranged on an end face of the cylinder 1 pinion 3, which cooperates with a drive unit, not shown. In the jacket 4 of the cylinder openings 5 are provided, in which immersed by angle plates 6 clamping elements. The clamping elements 6 are arranged to be movable and together with the side walls of the openings 5 each clamping devices 7. The movable clamping elements 6 are rigidly connected to carriage 8, which extend in the direction of the axis 2. In this case, each carriage 8 is connected to a single clamping plate 6, so that each clamping device can be actuated separately by displacement of the carriage 8 according to the double arrow 9. Each carriage 8 is guided here in each case on two of the circumferentially uniformly distributed bearing rods 10. The actuation of the carriage 8 via a disposed on each end face of the cylinder 1 pressure roller on which the carriage 8 accumulate with their end faces 11, so that a displacement of the carriage 8 results.

Der Mantel 4 des Zylinders 1 ist weiters mit so genannten Einfädelrillen 12 versehen, wobei jeder Klemmvorrichtung 7 eine Einfädelrille zugeordnet ist. Die Einfädelrillen 12 dienen dazu die auszuzupfenden Haare während der Rotation des Zylinders 1 derart in Bahnen zu lenken, dass sie den Klemmvorrichtungen 7 zugeführt werden. Zu diesem Zweck münden die Einfädelrillen 12 in den Durchbrechungen 5, wobei die Einfädelrillen 12 bis zur Klemmvorrichtung 7 stetig enger werdend ausgebildet sind. Der Mantel 4 des Zylinders 1 ist weiters über den gesamten Umfang mit Rippen 13 ausgebildet, welche während der Rotation des Zylinders 1 mit der Hautoberfläche in Berührung gelangen und zu einer Stimulation der Haut führen, sodass die durch das Auszupfen der Haare hervorgerufenen Schmerzreize überlagert werden und subjektiv weniger deutlich wahrgenommen werden. Dies führt zu einer deutlichen Schmerzreduktion bei dem Auszupfen der Haare.The jacket 4 of the cylinder 1 is further provided with so-called Einfädelrillen 12, wherein each clamping device 7 is associated with a threading groove. The threading grooves 12 serve to guide the hair to be dispensed during the rotation of the cylinder 1 in such a way that they are fed to the clamping devices 7. For this purpose, the threading grooves 12 open in the openings 5, wherein the threading grooves 12 are formed continuously narrowing to the clamping device 7. The jacket 4 of the cylinder 1 is further formed over the entire circumference with ribs 13, which come into contact with the skin surface during the rotation of the cylinder 1 and lead to a stimulation of the skin, so that caused by the plucking of the hair pain stimuli are superimposed and subjectively less clearly perceived. This leads to a significant pain reduction in the plucking of the hair.

In Fig. 2 ist nun der Drehzylinder 1 ohne den Außenmantel 4 dargestellt und es ist die Anordnung der Schlitten 8 mit den Klemmelementen 6 besser ersichtlich. Die Betätigung der einzelnen Klemmelemente erfolgt nun derart, dass jeweils 2 in Umfangsrichtung versetzt angeordnete Klemmvorrichtungen gleichzeitig betätigt werden.In Fig. 2, the rotary cylinder 1 is now shown without the outer shell 4 and it is the arrangement of the carriage 8 with the clamping elements 6 can be seen better. The actuation of the individual clamping elements takes place in such a way that in each case 2 circumferentially offset clamping devices are actuated simultaneously.

In Fig.2 sowie in der Detailansicht gemäß Fig.3 sind die Schlitten 14 und 15 samt den dazugehörigen Klemmelementen 16 und 17 als gleichzeitig betätigt und daher in einer zueinander verschobenen Lage dargestellt. Die Verschiebung der Schlitten 14 und 15 erfolgt wie bereits erwähnt über nicht näher dargestellte, stirnseitig angeordnete Druckrollen und gegen die Kraft einer zwischen den Schlitten 14 und 15 angeordneten Feder 18. Nach einer Rotation des Zylinders 1 um einen der Breite eines Schlittens entsprechenden Winkel werden die jeweils benachbarten Schlitten von den Druckrollen betätigt, wobei die Rückstellung der zuvor verschobenen Schlitten 14 und 15 durch die Kraft der Feder 18 erfolgt. Die Schlitten 14 und 15 sind auf zwei gemeinsamen Lagerstangen 19 und 20 geführt, wie dies noch deutlicher in Fig.3 dargestellt ist. Die Schlitten 14 und 15 weisen hierbei einen Basisbereich auf, mit welchem sie auf den Lagerstangen 19 und 20 geführt sind und einen oberen Bereich, auf welchem die Klemmelemente 16 bzw. 17 angeordnet und welcher in Umfangsrichtung versetzt ist.In Figure 2 and in the detail view according to Figure 3, the carriage 14 and 15 together with the associated clamping elements 16 and 17 are operated simultaneously and therefore shown in a mutually shifted position. The displacement of the carriage 14 and 15 is effected as already mentioned not shown, frontally arranged pressure rollers and against the force of a arranged between the carriage 14 and 15 spring 18. After rotation of the cylinder 1 by an angle of the width of a carriage corresponding angle each adjacent carriage actuated by the pressure rollers, wherein the provision of the previously displaced carriage 14 and 15 is effected by the force of the spring 18. The carriages 14 and 15 are guided on two common bearing rods 19 and 20, as shown more clearly in Fig.3. The carriages 14 and 15 in this case have a base region with which they are guided on the bearing rods 19 and 20 and an upper region on which the clamping elements 16 and 17 are arranged and which is offset in the circumferential direction.

In Fig.4 ist schematisch eine Abwicklung des Zylinders 1 dargestellt, wobei die Anordnung der einzelnen Klemmvorrichtungen 7 noch deutlicher ersichtlich ist. Die Achsrichtung des Drehzylinders 1 ist hierbei durch den Doppelpfeil 21 und die Umfangsrichtung durch den Doppelpfeil 22 angegeben. Beispielhaft sind wiederum die Klemmelemente 15 und 16 dargestellt, welche in Umfangsrichtung 22 versetzt angeordnet sind und gleichzeitig betätigt werden. Während der Rotation des Drehzylinders 1 werden nacheinander die in Umfangsrichtung 22 aufeinanderfolgenden Klemmelemente betätigt, wobei jeweils zwei in Umfangsrichtung versetzt angeordnete Klemmvorrichtungen gleichzeitig betätigt werden. Durch diese Art der Betätigung entsteht ein Zupfbereich, welcher dem Abstand a entspricht und welcher somit wesentlich größer ist als bei Epiliergeräten, bei welchen die Klemmvorrichtungen entlang einer sich in Achsrichtung 21 erstreckenden Linie bzw. Reihe betätigt werden.4, a development of the cylinder 1 is shown schematically, wherein the arrangement of the individual clamping devices 7 is even more clearly visible. The axial direction of the rotary cylinder 1 is indicated by the double arrow 21 and the circumferential direction by the double arrow 22. By way of example, in turn, the clamping elements 15 and 16 are shown, which are arranged offset in the circumferential direction 22 and are operated simultaneously. During the rotation of the rotary cylinder 1 successively operated in the circumferential direction 22 consecutive clamping elements, wherein each two circumferentially offset clamping devices are operated simultaneously. This type of actuation results in a plucking area which corresponds to the distance a and which is thus considerably larger than in depilation machines in which the clamping devices are actuated along a line or row extending in the axial direction 21.
