Definitions

  • the invention relates to a razor with a housing, and with a shaving head frame releasably held on the housing and with a lower knife provided essentially within the shaving head frame with a cutting area which is curved with respect to an axis of curvature and which can be driven back and forth at least parallel to the axis of curvature and with a foil knife frame pivotally mounted in the shaving head frame about a pivot axis running parallel to the axis of curvature, to which is attached a foil-like upper knife lying against the cutting area of the bottom knife and having hair passage holes, which has at least two hole fields that differ in terms of the formation of the hair passage holes, and with a handle provided for adjusting the film knife frame, which can be adjusted by hand, which is coupled to the film knife frame via an adjustable adjusting device and by the actuation thereof Unable to pivot about its pivot axis via the adjustment device of the foil knife frame and thereby one of the perforated fields of the upper knife can be brought into operative connection with the cutting area of the lower knife
  • a shaving device for example from DE 20 33 198 A.
  • the handle is formed by a small rotary knob held rotatably on the shaving head frame, and the adjusting device is formed by a square pin protruding from the foil knife frame, which protrudes into a recess in the rotary knob.
  • Such a design is relatively simple, but has some disadvantages, because when the handle provided on the shaving head frame is actuated, unfavorable loads in the direction of the axis of curvature can come from the devices holding the shaving head frame on the housing, because the adjusting device acts on one side of the film knife frame and therefore no uniform distribution of forces occurs on the film measuring frame, because the handle is only relatively small and can be unwieldy because only a relatively uncomfortable handling of the shaving device when operating the handle is possible, since to operate the handle of the shaving device held in one hand it is necessary to reach around this hand or the second hand, and because the handle is only relatively difficult additional operating functions can be controlled.
  • the invention has for its object to provide a training in a razor according to the type mentioned in the first paragraph, that is, in a razor that has a foil knife frame for holding the foil-like upper knife, in which the problems, as in the case of the DE 20 33 198 A known device are available, are avoided and in which a secure pivoting of the foil knife frame with the adjusting device and a uniform force distribution of the adjusting forces exerted by the adjusting device on the foil knife frame is ensured.
  • the handle for adjusting the film-like upper knife is held adjustable on the housing of the razor and that the adjusting device has an adjustable frame under the film knife frame in its area facing away from the upper knife, which is pivotally mounted in the razor about a pivot axis which runs parallel to the pivot axis of the foil knife frame.
  • a particularly simple decoupling of the foil knife frame and the adjustment device for the foil knife frame is achieved when removing the shaving head frame, because here only the foil knife frame is moved away from the adjustment frame under it without having to release positive connections between the two frames.
  • the currently set position of the adjusting frame is retained, so that when the shaving head frame is replaced, the foil knife frame is automatically pivoted from the adjusting frame into its position selected before the shaving head frame was removed.
  • JP-U 3-965 it is known per se, for example from JP-U 3-965, to provide a handle for adjusting a film-like upper knife on the housing of a razor and to keep it adjustable there.
  • This JP-U 3-965 shows a razor with a housing and with a shaving head frame detachably held on the housing and with an adjustable film-like upper knife and with a handle provided for adjusting the upper knife, which is adjustable on the housing and which has an essentially fork-like handle Adjusting slide is coupled as an adjustment device with the film-like upper knife.
  • the adjustment frame can be mounted so as to be pivotable about a pivot axis which is offset with respect to the pivot axis of the foil knife frame, but there is then a relative movement between the adjustment frame and the foil knife frame. It has therefore proven to be particularly advantageous if the adjustment frame about a pivot axis is pivotally mounted, which escapes with the pivot axis of the foil knife frame. This is very advantageous with regard to the adjustment of the foil knife frame with as little friction as possible.
  • the adjustment frame lies essentially within the foil knife frame and four extensions, which extend in pairs and in opposite directions from the adjustment frame, extend from the adjustment frame and extend away from the adjustment frame, with which the Adjustment frame engages under two frame sections of the foil knife frame that run parallel to the swivel axis of the foil knife frame.
  • the handle is formed by a sliding button, with which an adjusting lever of the adjusting device is articulated, which is also articulated with the adjusting frame of the adjusting device. This is advantageous with regard to a construction that is as simple as possible in terms of construction.

  • FIG. 2 shows the shaving head area of the shaving apparatus according to FIG. 1 with the two tooth cutting devices omitted, the sliding button being in its switched-off position and the screen shaving foil being in its rest position.
  • FIG. 3 shows a cross section of the shaving head area of the shaving apparatus according to FIG. 1 with the two tooth cutting devices omitted, the slide button is in its switch-off position and the screen shear film is in its rest position.

Description

Die Erfindung bezieht sich auf ein Rasiergerät mit einem Gehäuse, und mit einem an dem Gehäuse lösbar festgehaltenen Scherkopfrahmen und mit einem im wesentlichen innerhalb des Scherkopfrahmens vorgesehenen Untermesser mit einem bezüglich einer Krümmungsachse gekrümmt verlaufenden Schneidbereich, das zumindest parallel zu der Krümmungsachse hin- und hergehend antreibbar ist, und mit einem in dem Scherkopfrahmen um eine parallel zur Krümmungsachse verlaufende Schwenkachse verschwenkbar gelagerten Folienmesserrahmen, an dem ein an dem Schneidbereich des Untermessers anliegendes, Haardurchtrittslöcher aufweisendes folienartiges Obermesser angebracht ist, das mindestens zwei hinsichtlich der Ausbildung der Haardurchtrittslöcher unterschiedliche Lochfelder aufweist, und mit einer zum Verstellen des Folienmesserrahmens vorgesehenen, von Hand aus verstellbaren Handhabe, die über eine verstellbare Verstelleinrichtung mit dem Folienmesserrahmen gekoppelt ist und durch deren Betätigung über die Verstelleinrichtung der Folienmesserrahmen um seine Schwenkachse verschwenkbar und dadurch jeweils eines der Lochfelder des Obermessers mit dem Schneidbereich des Untermessers in Wirkverbindung bringbar ist.The invention relates to a razor with a housing, and with a shaving head frame releasably held on the housing and with a lower knife provided essentially within the shaving head frame with a cutting area which is curved with respect to an axis of curvature and which can be driven back and forth at least parallel to the axis of curvature and with a foil knife frame pivotally mounted in the shaving head frame about a pivot axis running parallel to the axis of curvature, to which is attached a foil-like upper knife lying against the cutting area of the bottom knife and having hair passage holes, which has at least two hole fields that differ in terms of the formation of the hair passage holes, and with a handle provided for adjusting the film knife frame, which can be adjusted by hand, which is coupled to the film knife frame via an adjustable adjusting device and by the actuation thereof Unable to pivot about its pivot axis via the adjustment device of the foil knife frame and thereby one of the perforated fields of the upper knife can be brought into operative connection with the cutting area of the lower knife.

Ein Rasiergerät gemäß der vorstehend im ersten Absatz angeführten Gattung ist beispielsweise aus der DE 20 33 198 A bekannt. Bei diesem bekannten Rasiergerät ist die Handhabe durch einen am Scherkopfrahmen verdrehbar gehaltenen kleinen Drehknopf und die Verstelleinrichtung durch einen vom Folienmesserrahmen abstehenden Vierkantstift gebildet, der in eine Ausnehmung in dem Drehknopf ragt. Eine solche Ausbildung ist zwar relativ einfach, hat aber doch einige Nachteile, weil es beim Betätigen der am Scherkopfrahmen vorgesehenen Handhabe zu ungünstigen Belastungen in Richtung der Krümmungsachse von den Scherkopfrahmen am Gehäuse festhaltenden Einrichtungen kommen kann, weil die Verstelleinrichtung an dem Folienmesserrahmen einseitig angreift und daher an dem Folienmesserahmen keine gleichmäßige Kräfteverteilung auftritt, weil die Handhabe nur relativ klein und unhandlich ausgebildet sein kann, weil nur eine relativ unbequeme Handhabung des Rasiergerätes beim Betätigen der Handhabe möglich ist, da zum Betätigen der Handhabe des in einer Hand gehaltenen Rasiergerätes ein Umgreifen dieser Hand oder die zweite Hand erforderlich ist, und weil mit der Handhabe nur relativ schwierig zusätzliche Betriebsfunktionen steuerbar sind.A shaving device according to the type mentioned above in the first paragraph is known for example from DE 20 33 198 A. In this known shaving device, the handle is formed by a small rotary knob held rotatably on the shaving head frame, and the adjusting device is formed by a square pin protruding from the foil knife frame, which protrudes into a recess in the rotary knob. Such a design is relatively simple, but has some disadvantages, because when the handle provided on the shaving head frame is actuated, unfavorable loads in the direction of the axis of curvature can come from the devices holding the shaving head frame on the housing, because the adjusting device acts on one side of the film knife frame and therefore no uniform distribution of forces occurs on the film measuring frame, because the handle is only relatively small and can be unwieldy because only a relatively uncomfortable handling of the shaving device when operating the handle is possible, since to operate the handle of the shaving device held in one hand it is necessary to reach around this hand or the second hand, and because the handle is only relatively difficult additional operating functions can be controlled.

Die Erfindung hat sich zur Aufgabe gestellt, bei einem Rasiergerät gemäß der im ersten Absatz angeführten Gattung, also bei einem Rasiergerät, das zur Halterung des folienartigen Obermessers einen Folienmesserrahmen aufweist, eine Ausbildung zu schaffen, bei der die Probleme, wie sie bei dem aus der DE 20 33 198 A bekannten Gerät vorhanden sind, vermieden sind und bei der ein sicheres Verschwenken des Folienmesserrahmens mit der Verstelleinrichtung und eine gleichmäßige Kräfteverteilung der von der Verstelleinrichtung auf den Folienmesserrahmen ausgeübten Verstellkräfte gewährleistet ist. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Handhabe zum Verstellen des folienartigen Obermessers an dem Gehäuse des Rasiergerätes verstellbar gehalten ist und daß die Verstelleinrichtung einen den Folienmesserrahmen in dessen vom Obermesser abgewandten Bereich untergreifenden Verstellrahmen aufweist, der in dem Rasiergerät um eine Schwenkachse verschwenkbar gelagert ist, die zu der Schwenkachse des Folienmesserrahmens parallel verläuft. Auf diese Weise ist erreicht, daß eine einfache und bequeme Handhabung des Rasiergerätes beim Betätigen der Handhabe gewährleistet ist, weil zum Betätigen der Handhabe des in einer Hand gehaltenen Rasiergerätes kein Umgreifen dieser Hand und keine zweite Hand erforderlich ist, und daß die Handhabe relativ groß und handlich ausgebildet werden kann und daß mit der Handhabe leicht und einfach zusätzliche Betriebsfunktionen, wie etwa das Ein- und Ausschalten des Motors, gesteuert werden können und daß darüber hinaus zusätzlich ein besonders einfaches und betriebssicheres Koppeln der Verstelleinrichtung mit dem Folienmesserrahmen durch das Untergreifen des Folienmesserrahmens mit dem Verstellrahmen beim Aufsetzen des Scherkopfrahmens auf das Gehäuse des Rasiergerätes und ein besonders gutes und sicheres Verschwenken des Folienmesserrahmens mit dem Verstellrahmen erreicht wird, wobei mit dem Jerstellrahmen ein hinsichtlich der angreifenden Verstellkräfte vorteilhafterweise gleichmäßig verteiltes Angreifen am Folienmesserrahmen erfolgt. Auch ist ein besonders einfaches Entkoppeln des Folienmesserrahmens und der Verstelleinrichtung für den Folienmesserrahmen beim Abnehmen des Scherkopfrahmens erreicht, weil hierbei lediglich der Folienmesserrahmen von dem ihn untergreifenden Verstellrahmen wegverstellt wird, ohne daß formschlüssige Verbindungen zwischen den beiden Rahmen gelöst werden müssen. Beim Abnehmen des Scherkopfrahmens bleibt die momentan eingestellte Position des Verstellrahmens erhalten, so daß bei einem neuerlichen Aufsetzen des Scherkopfrahmens der Folienmesserrahmen von dem Verstellrahmen automatisch in seine vor dem Abnehmen des Scherkopfrahmens gewählte Position verschwenkt wird.The invention has for its object to provide a training in a razor according to the type mentioned in the first paragraph, that is, in a razor that has a foil knife frame for holding the foil-like upper knife, in which the problems, as in the case of the DE 20 33 198 A known device are available, are avoided and in which a secure pivoting of the foil knife frame with the adjusting device and a uniform force distribution of the adjusting forces exerted by the adjusting device on the foil knife frame is ensured. This object is achieved in that the handle for adjusting the film-like upper knife is held adjustable on the housing of the razor and that the adjusting device has an adjustable frame under the film knife frame in its area facing away from the upper knife, which is pivotally mounted in the razor about a pivot axis which runs parallel to the pivot axis of the foil knife frame. In this way it is achieved that a simple and convenient handling of the shaving device is ensured when operating the handle, because no operation of this hand and no second hand is required to operate the handle of the shaving device held in one hand, and that the handle is relatively large and can be designed to be handy and that additional operating functions, such as switching the motor on and off, can be controlled easily and simply with the handle and, in addition, a particularly simple and reliable coupling of the adjusting device to the film knife frame by reaching under the film knife frame the adjustment frame when the shaving head frame is placed on the housing of the razor and a particularly good and safe pivoting of the foil knife frame with the adjustment frame is achieved, with the adjustment frame advantageously a g with respect to the attacking adjustment forces easily distributed attack on the foil knife frame. A particularly simple decoupling of the foil knife frame and the adjustment device for the foil knife frame is achieved when removing the shaving head frame, because here only the foil knife frame is moved away from the adjustment frame under it without having to release positive connections between the two frames. When the shaving head frame is removed, the currently set position of the adjusting frame is retained, so that when the shaving head frame is replaced, the foil knife frame is automatically pivoted from the adjusting frame into its position selected before the shaving head frame was removed.

Es sei erwähnt, daß es an sich beispielsweise aus dem JP-U 3-965 bekannt ist, eine Handhabe zum Verstellen eines folienartigen Obermessers an dem Gehäuse eines Rasiergerätes vorzusehen und dort verstellbar zu halten. Dieses JP-U 3-965 zeigt ein Rasiergerät mit einem Gehäuse und mit einem an dem Gehäuse lösbar festgehaltenen Scherkopfrahmen und mit einem verstellbaren folienartigen Obermesser und mit einer zum Verstellen des Obermessers vorgesehenen, an dem Gehäuse verstellbar gehaltenen Handhabe, die über einen im wesentlichen gabelartigen Verstellschieber als Verstelleinrichtung mit dem folienartigen Obermesser gekoppelt ist. Bei diesem Rasiergerät ist aber kein Folienmesserrahmen vorgesehen, sondern das folienartige Obermesser ist lediglich an seinen beiden quer zu seinen Verstellrichtungen verlaufenden Enden mit je einer Führungsleiste verbunden, von denen eine über je eine Stift-Loch-Verbindung mit je einem der beiden Enden des gabelartigen Verstellschiebers gekoppelt ist. Demgegenüber bildet aber ein verschwenkbarer Folienmesserrahmen eine wesentlich stabilere und sicherere Halterung für das folienartige Obermesser als eine Halterung mittels zweier Führungsleisten. Weiters erfordert das Koppeln bzw. Entkoppeln des gabelartigen Verstellschiebers mit der betreffenden Führungsleiste, was beim Aufsetzen bzw. Abnehmen des Scherkopfrahmens erforderlich ist, eine eigene und unbequeme Manipulation, was hinsichtlich einer möglichst einfachen Handhabung nachteilig ist.It should be mentioned that it is known per se, for example from JP-U 3-965, to provide a handle for adjusting a film-like upper knife on the housing of a razor and to keep it adjustable there. This JP-U 3-965 shows a razor with a housing and with a shaving head frame detachably held on the housing and with an adjustable film-like upper knife and with a handle provided for adjusting the upper knife, which is adjustable on the housing and which has an essentially fork-like handle Adjusting slide is coupled as an adjustment device with the film-like upper knife. In this razor, however, no foil knife frame is provided, but the foil-like upper knife is only connected at its two ends running transversely to its adjustment directions, each with a guide bar, one of which has a pin-hole connection with one of the two ends of the fork-like adjustment slide is coupled. In contrast, however, a pivotable film knife frame forms a much more stable and secure holder for the film-like upper knife than a holder by means of two guide strips. Furthermore, the coupling or decoupling of the fork-like adjusting slide with the guide bar in question, which is necessary when putting on or taking off the shaving head frame, requires its own and uncomfortable manipulation, which is disadvantageous with regard to the simplest possible handling.

Bei einem erfindungsgemäßen Rasiergerät kann der Verstellrahmen um eine Schwenkachse verschwenkbar gelagert sein, die gegenüber der Schwenkachse des Folienmesserrahmens versetzt verläuft, wobei es aber dann zu einer Relativbewegung zwischen dem Verstellrahmen und dem Folienmesserrahmen kommt. Als besonders vorteilhaft hat sich daher erwiesen, wenn der Verstellrahmen um eine Schwenkachse verschwenkbar gelagert ist, die mit der Schwenkachse des Folienmesserrahmens flüchtet. Dies ist hinsichtlich einer möglichst reibungsarmen Verstellung des Folienmesserrahmens durch den Verstellrahmen sehr vorteilhaft.In a shaving device according to the invention, the adjustment frame can be mounted so as to be pivotable about a pivot axis which is offset with respect to the pivot axis of the foil knife frame, but there is then a relative movement between the adjustment frame and the foil knife frame. It has therefore proven to be particularly advantageous if the adjustment frame about a pivot axis is pivotally mounted, which escapes with the pivot axis of the foil knife frame. This is very advantageous with regard to the adjustment of the foil knife frame with as little friction as possible.

Als vorteilhaft hat sich auch erwiesen, wenn in Draufsicht auf den Folienmesserrahmen und den Verstellrahmen der Verstellrahmen im wesentlichen innerhalb des Folienmesserrahmens liegt und von dem Verstellrahmen vier quer zur Schwenkachse des Verstellrahmens verlaufende, paarweise in entgegengesetzten Richtungen von dem Verstellrahmen weggerichtete Fortsätze abstehen, mit denen der Verstellrahmen zwei parallel zur Schwenkachse des Folienmesserrahmens verlaufende Rahmenabschnitte des Folienmesserrahmens untergreift. Dies ist im Hinblick auf eine möglichst einfache und raumsparende Ausbildung vorteilhaft.It has also proven to be advantageous if, in a top view of the foil knife frame and the adjustment frame, the adjustment frame lies essentially within the foil knife frame and four extensions, which extend in pairs and in opposite directions from the adjustment frame, extend from the adjustment frame and extend away from the adjustment frame, with which the Adjustment frame engages under two frame sections of the foil knife frame that run parallel to the swivel axis of the foil knife frame. This is advantageous in view of the simplest and most space-saving training possible.

Als besonders vorteilhaft hat sich weiters erwiesen, wenn die Handhabe durch eine Schiebetaste gebildet ist, mit der ein Verstellhebel der Verstelleinrichtung gelenkig verbunden ist, der mit dem Verstellrahmen der Verstelleinrichtung ebenfalls gelenkig verbunden ist. Dies ist im Hinblick auf eine in konstruktiver Hinsicht möglichst einfache Ausbildung vorteilhaft.It has also proven to be particularly advantageous if the handle is formed by a sliding button, with which an adjusting lever of the adjusting device is articulated, which is also articulated with the adjusting frame of the adjusting device. This is advantageous with regard to a construction that is as simple as possible in terms of construction.

Die Fig.1 zeigt ein Rasiergerät 1, bei dem es sich um einen sogenannten Damenrasierer handelt. Das Rasiergerät 1 ist hierbei mit seinem fußseitigen Ende 2 in einen Aufnahmeraum 3 eines Ladegerätes 4 eingesteckt, um in dem Rasiergerät 1 untergebrachte aufladbare Akkumulatoren aufzuladen.1 shows a shaving device 1, which is a so-called women's razor. The shaving device 1 is inserted with its foot end 2 into a receiving space 3 of a charger 4 in order to charge rechargeable batteries accommodated in the shaving device 1.

Das Rasiergerät 1 weist ein Gehäuse 5 auf, das einem leicht geschwungenen Verlauf folgt. Auf dem Gehäuse 5 sitzt ein Scherkopfrahmen 6, der an dem Gehäuse 5 mit nicht dargestellten Rasteinrichtungen lösbar festgehalten ist. Zum Lösen der Rasteinrichtungen sind am Scherkopfrahmen 6 an gegenüberliegenden Seiten zwei Drucktasten 7 vorgesehen, von denen in Fig.1 eine Drucktaste 7 sichtbar ist. In dem Scherkopfrahmen 6 ist eine Kurzhaarschneideinrichtung 8 und sind weiters zwei Langhaarschneideinrichtungen 9 und 10 untergebracht. Die Kurzhaarschneideinrichtung 8 weist ein folienartiges Obermesser 11, das im folgenden kurz Siebscherfolie 11 genannt wird, sowie ein antreibbares Untermesser 12 auf, das als Lamellenmesser mit einer Vielzahl von Messerlamellen 13 bzw. Messerklingen ausgebildet ist, wie dies aus Fig.5 ersichtlich ist. Die Langhaarsehneideinrichtungen 9 und 10 sind in bekannter Weise durch Zahnschneideinrichtungen gebildet. Von den beiden Langhaarschneideinrichtungen 9 und 10 ist die eine Langhaarschneideinrichtung 9 gegenüber dem Scherkopfrahmen 6 unverstellbar gehalten, wogegen die andere Langhaarschneideinrichtung 10 gegenüber dem Scherkopfrahmen 6 verstellbar gehalten ist, und zwar zwischen einer in Fig.1 dargestellten Ruheposition und einer nicht dargestellten Betriebsposition, in der die andere Langhaarschneideinrichtung 10 aus dem Scherkopfrahmen 6 herausgeschoben ist.The shaving apparatus 1 has a housing 5 which follows a slightly curved course. A shaving head frame 6 is seated on the housing 5 and is detachably held on the housing 5 with latching devices (not shown). To the To release the locking devices, two push buttons 7 are provided on the shaving head frame 6 on opposite sides, of which a push button 7 is visible in FIG. In the shaving head frame 6 is a short hair cutting device 8 and two long hair cutting devices 9 and 10 are also housed. The short-hair cutting device 8 has a film-like upper knife 11, which is referred to below as sieve shear film 11, and a drivable lower knife 12, which is designed as a lamellar knife with a plurality of knife lamellae 13 or knife blades, as can be seen from FIG. The long hair cutting devices 9 and 10 are formed in a known manner by tooth cutting devices. Of the two long hair cutting devices 9 and 10, one long hair cutting device 9 is held immovably relative to the shaving head frame 6, whereas the other long hair cutting device 10 is held adjustable relative to the shaving head frame 6, namely between a rest position shown in FIG. 1 and an operating position, not shown, in which the other long hair cutting device 10 is pushed out of the shaving head frame 6.

Wie erwähnt, weist die Kurzhaarschneideinrichtung 8 ein Untermesser 12 auf, das innerhalb des Scherkopfrahmens 6 vorgesehen ist und das einen bezüglich einer in den Figuren nicht näher mit einem Bezugszeichen bezeichneten Krümmungsachse gekrümmt verlaufenden Schneidbereich 14 aufweist, der durch die Schneidflächen bzw. Schneidkanten der Lamellen 13 des Untermesser 12 gebildet ist. Die vorerwähnte Krümmungsachse verläuft hierbei senkrecht zu zwei Querwänden 15 und 16 und parallel zu zwei Längswänden 17 und 18 des Scherkopfrahmens 6. Das Untermesser 12 ist parallel zu der Krümmungsachse hin- und hergehend antreibbar, wofür das Rasiergerät 1 einen mit dem Untermesser 12 in Antriebsverbindung stehenden, parallel zur Krümmungsachse entsprechend dem in Fig.5 dargestellten Doppelpfeil 19 hin- und hergehend antreibbaren Antriebsteil 20 aufweist, der auf nicht näher dargestellte Weise von einem Antriebsmotor des Rasiergerätes 1 antreibbar ist.As mentioned, the short hair cutting device 8 has a lower knife 12, which is provided within the shaving head frame 6 and which has a cutting region 14, which runs in a curved manner with respect to an axis of curvature, not shown in the figures with a reference number, and which extends through the cutting surfaces or cutting edges of the lamellae 13 of the lower knife 12 is formed. The above-mentioned axis of curvature here runs perpendicular to two transverse walls 15 and 16 and parallel to two longitudinal walls 17 and 18 of the shaving head frame 6. The bottom knife 12 can be driven back and forth parallel to the axis of curvature, for which the shaving device 1 is a drive connection with the bottom knife 12 , parallel to the axis of curvature according to the double arrow 19 shown in FIG. 5 to and fro drivable drive part 20 which can be driven in a manner not shown by a drive motor of the shaving apparatus 1.

Wie erwähnt, weist die Kurzhaarschneideinrichtung 8 eine Siebscherfolie 11 auf. Die Siebscherfolie 11 ist hierbei an einem Folienmesserrahmen 21 angebracht. Der Folienmesserrahmen 21 weist zwei parallel zu den Querwänden 15 und 16 des Scherkopfrahmens 6 verlaufende Stirnwände 22 und 23 auf, die über zwei parallel zu den Längswänden 17 und 18 des Scherkopfrahmens 6 und parallel zu der erwähnten Krümmungsachse verlaufende Rahmenstege 24 und 25 miteinander verbunden sind. Die Siebscherfolie 11 ist hierbei an den Rahmenstegen 24 und 25 mit Hilfe von ultraschallgeschweißten Noppen befestigt. Der Folienmesserrahmen 21 ist um eine parallel zur Krümmungsachse verlaufende Schwenkachse 26 in dem Scherkopfrahmen 6 verschwenkbar gelagert. Hierfür weist der Folienmesserrahmen 21 zwei von seinen Stirnwänden 22 und 23 nach außen hin abstehende zylindrische Lagerstummel 27 und 28 auf, die in Lagerbohrungen 29 und 30 in den Querwänden 15 und 16 des Scherkopfrahmens 6 drehbar aufgenommen sind.As mentioned, the short hair cutting device 8 has a screen shaving foil 11. The screen shear film 11 is attached to a film knife frame 21. The foil knife frame 21 has two end walls 22 and 23 which run parallel to the transverse walls 15 and 16 of the shaving head frame 6 and which are connected to one another via two frame webs 24 and 25 which run parallel to the longitudinal walls 17 and 18 of the shaving head frame 6 and parallel to the mentioned axis of curvature. The Sieve shear foil 11 is fastened to the frame webs 24 and 25 with the aid of ultrasonically welded knobs. The foil knife frame 21 is mounted in the shaving head frame 6 so as to be pivotable about a pivot axis 26 running parallel to the axis of curvature. For this purpose, the foil knife frame 21 has two cylindrical bearing stubs 27 and 28 which project outwardly from its end walls 22 and 23 and are rotatably received in bearing bores 29 and 30 in the transverse walls 15 and 16 of the shaving head frame 6.

Die Siebscherfolie 11 weist in bekannter Weise Haardurchtrittslöcher auf. Beim vorliegenden Rasiergerät 1 weist die Siebscherfolie 11 zwei hinsichtlich der Ausbildung der Haardurchtrittslöcher unterschiedliche Lochfelder 31 und 32 auf, wobei in dem Lochfeld 31 größere Haardurchtrittslöcher 33 zum Schneiden von Haaren an den Beinen und wobei in dem Lochfeld 32 Kleinere Haardurchtrittslöcher 34 zum Schneiden von Haaren im Achselbereich vorgesehen sind.The sieve shear foil 11 has hair passage holes in a known manner. In the present shaving apparatus 1, the screen shaving foil 11 has two perforated fields 31 and 32 which are different with regard to the formation of the hair penetration holes, larger perforation holes 33 for cutting hair on the legs in the perforated field 31 and smaller hair penetration holes 34 for cutting hair in the perforated field 32 Underarm area are provided.

Das Rasiergerät 1 weist eine zum Verstellen des Folienmesserrahmens 21 vorgesehene, von Hand aus verstellbare Handhabe 35 auf, die durch eine Schiebetaste gebildet ist. Die Schiebetaste 35 ist über eine verstellbare Verstelleinrichtung 36 mit dem Folienmesserrahmen 21 gekoppelt. Durch die Betätigung der Schiebetaste 35 ist über die Verstelleinrichtung 36 der Folienmesserrahmen 21 um seine Schwenkachse 26 verschwenkbar und dadurch jeweils eines der beiden Lochfelder 31 und 32 der Siebscherfolie 11 mit dem Schneidbereich 14 des Untermessers 12 in Wirkverbindung bringbar.The shaving apparatus 1 has a handle 35, which is provided for adjusting the foil knife frame 21 and is adjustable by hand, which is formed by a sliding button. The sliding button 35 is coupled to the foil knife frame 21 via an adjustable adjusting device 36. By actuating the sliding button 35, the foil knife frame 21 can be pivoted about its pivot axis 26 via the adjusting device 36 and thereby one of the two perforated fields 31 and 32 of the sieve shear foil 11 can be brought into operative connection with the cutting area 14 of the bottom knife 12.

Bei dem vorliegenden Rasiergerät 1 ist nunmehr die Schiebetaste 35 zum Verstellen der Siebscherfolie 11 an dem Gehäuse 5 des Rasiergerätes 1 verstellbar gehalten, und zwar an der der einen Längswand 17 des Scherkopfrahmens 6 benachbarten Wand 37 des Gehäuses 5 des Rasiergerätes 1. Die Schiebetaste 35 ist hierbei zwischen einer in den Figuren 1, 2, 3 und 5 dargestellten Ausschaltposition und einer in den Figuren 6 und 7 dargestellten ersten Einschaltposition sowie einer in den Figuren 8 und 9 dargestellten zweiten Einschaltposition verschiebbar.In the present shaving device 1, the sliding button 35 for adjusting the sieve shaving foil 11 on the housing 5 of the shaving device 1 is now held adjustably, namely on the wall 37 of the housing 5 of the shaving device 1 adjacent to the one longitudinal wall 17 of the shaving head frame 6. The sliding button 35 is displaceable between a switch-off position shown in FIGS. 1, 2, 3 and 5 and a first switch-on position shown in FIGS. 6 and 7 and a second switch-on position shown in FIGS. 8 and 9.

Bei in ihrer Ausschaltposition befindlicher Schiebetaste 35 ist über die Verstelleinrichtung 36 der Folienmesserrahmen 21 in einer solchen Position gehalten, daß die Siebscherfolie 11 eine Ruheposition einnimmt, in der der Übergangsbereich zwischen den beiden Lochfeldern 31 und 32 im Scheitelpunkt des gekrümmt verlaufenden Schneidbereiches 14 des Untermessers 12 liegt. Bei in ihrer Ausschaltposition befindlicher Schiebetaste 35 ist von der Schiebetaste 35 her zugleich auch der Antriebsmotor des Rasiergerätes 1 abgeschaltet, was nicht näher dargestellt ist. Bei in ihrer ersten Einschaltposition befindlicher Schiebetaste 35 ist über die Verstelleinrichtung 36 der Folienmesserrahmen 21 in seiner in Fig.7 dargestellten Betriebsposition verschwenkt gehalten, wobei dann das Lochfeld 32 mit den kleineren Haardurchtrittslöchern 34 mit dem Schneidbereich 14 des Untermessers 12 in Wirkverbindung steht, wie dies aus Fig.6 ersichtlich ist.When the slide button 35 is in its switched-off position, the film knife frame 21 is held in such a position by the adjusting device 36 that the screen shear film 11 assumes a rest position in which the transition area between the two perforated fields 31 and 32 at the apex of the curved cutting area 14 of the lower knife 12 lies. At in their The slide button 35 in the off position is also switched off by the slide button 35, the drive motor of the shaving apparatus 1, which is not shown in detail. When the slide button 35 is in its first switch-on position, the foil knife frame 21 is held pivoted in its operating position shown in FIG. 7 via the adjusting device 36, the hole field 32 with the smaller hair passage holes 34 then being operatively connected to the cutting area 14 of the lower knife 12, as is the case here can be seen from Fig. 6.

Bei in ihrer ersten Einschaltposition befindlicher Schiebetaste 35 ist von der Schiebetaste 35 her auch der Antriebsmotor des Rasiergerätes 1 eingeschaltet. Bei in ihrer zweiten Einschaltposition befindlicher Schiebetaste 35 ist über die Verstelleinrichtung 36 der Folienmesserrahmen 21 in seiner in Fig.9 dargestellten Betriebsposition verschwenkt gehalten, wobei dann das Lochfeld 31 mit den größeren Haardurchtrittslöchern 33 mit dem Schneidbereich 14 des Untermessers 12 in Wirkverbindung steht, wie dies aus Fig.8 ersichtlich ist. Bei in ihrer zweiten Einschaltposition befindlicher Schiebetaste 35 ist von der Schiebetaste 35 her auch der Antriebsmotor des Rasiergerätes 1 eingeschaltet. In den beiden Einschaltpositionen der Schiebetaste 35 kann das Untermesser 12 vom Antriebsmotor des Rasiergerätes 1 her mit unterschiedlichen Geschwindigkeiten hin- und hergehend angetrieben werden.When the slide button 35 is in its first switch-on position, the drive motor of the shaving device 1 is also switched on from the slide button 35. When the slide button 35 is in its second switch-on position, the film knife frame 21 is held pivoted in its operating position shown in FIG. 9 via the adjusting device 36, the hole field 31 with the larger hair passage holes 33 then being operatively connected to the cutting area 14 of the lower knife 12, as is the case here can be seen from Fig. 8. When the slide button 35 is in its second switch-on position, the drive motor of the shaving device 1 is also switched on from the slide button 35. In the two switch-on positions of the sliding button 35, the lower knife 12 can be driven back and forth by the drive motor of the shaving device 1 at different speeds.

Bei dem Rasiergerät 1 weist die Verstelleinrichtung 36 zum Verstellen des Folienmesserrahmens 21 in vorteilhafter Weise einen Verstellrahmen 38 auf, der den Folienmesserrahmen 21 in dessen von der Siebscherfolie 11 abgewandten Bereich untergreift, was nachfolgend noch detailliert erläutert ist. Der Verstellrahmen 38 weist in ähnlicher Weise wie der Folienmesserrahmen 21 zwei parallel zu den Querwänden 15 und 16 des Scherkopfrahmens 6 bzw. parallel zu den Stirnwänden 22 und 23 des Folienmesserrahmens 21 verlaufende Stirnwände 39 und 40 auf. Die Stirnwände 39 und 40 sind mit zwei parallel zu den Längswänden 17 und 18 des Scherkopfrahmens 6 und parallel zu den Rahmenstegen 24 und 25 des Folienmesserrahmens 21 verlaufenden Rahmenstegen 41 und 42 miteinander verbunden. Der Verstellrahmen 38 ist in dem Rasiergerät 1 um eine Schwenkachse 43 verschwenkbar gelagert, die zu der Schwenkachse 26 des Folienmesserrahmens 21 parallel verläuft. Bei dem vorliegenden Rasiergerät 1 ist die Ausbildung so getroffen, daß der Verstellrahmen 38 um eine Schwenkachse 43 verschwenkbar gelagert ist, die mit der Schwenkachse 26 des Folienmesserrahmens 21 fluchtet, so daß beim Verschwenken der beiden Rahmen 21 und 38 zwischen denselben praktisch keine Relativbewegungen auftreten. Zur verschwenkbaren Lagerung des Verstellrahmens 38 sind zwei in dem Rasiergerät 1 vorgesehene Lagerböcke 44 und 45 vorgesehen, die von einer Trägerplatte 61 senkrecht abstehen. Im Bereich der Enden der Lagerböcke 44 und 45 stehen von denselben zwei aufeinander zu gerichtete zylindrische Lagerstummel 46 und 47 ab, die in Lagerbohrungen 48 und 49 in den Stirnwänden 39 und 40 des Verstellrahmens 38 hineinragen.In the shaving apparatus 1, the adjusting device 36 for adjusting the foil knife frame 21 advantageously has an adjusting frame 38 which engages under the foil knife frame 21 in its area facing away from the sieve shear foil 11, which is explained in detail below. In a manner similar to the film knife frame 21, the adjustment frame 38 has two end walls 39 and 40 running parallel to the transverse walls 15 and 16 of the shaving head frame 6 or parallel to the end walls 22 and 23 of the film knife frame 21. The end walls 39 and 40 are connected to one another by two frame webs 41 and 42 running parallel to the longitudinal walls 17 and 18 of the shaving head frame 6 and parallel to the frame webs 24 and 25 of the foil knife frame 21. The adjustment frame 38 is mounted in the shaving device 1 so as to be pivotable about a pivot axis 43 which runs parallel to the pivot axis 26 of the foil knife frame 21. In the present razor 1, the design is such that the adjustment frame 38 is pivotally mounted about a pivot axis 43 which is aligned with the pivot axis 26 of the foil knife frame 21, so that when the two frames 21 are pivoted and 38 there are virtually no relative movements between them. For the pivotable mounting of the adjustment frame 38, two bearing blocks 44 and 45 are provided in the shaving apparatus 1 and protrude vertically from a carrier plate 61. In the area of the ends of the bearing blocks 44 and 45 two cylindrical bearing stubs 46 and 47 project from the same, which protrude into bearing bores 48 and 49 in the end walls 39 and 40 of the adjusting frame 38.

In Draufsicht auf den Folienmesserrahmen 21 und den Verstellrahmen 38 liegt der Verstellrahmen 38 im wesentlichen innerhalb des Folienmesserrahmens 21. Von dem Verstellrahmen 38, und zwar von dessen Stirnwänden 39 und 40 stehen vier quer zur Schwenkachse 43 des Verstellrahmens 38 verlaufende, paarweise in entgegengesetzten Richtungen von dem Verstellrahmen weggerichtete Fortsätze 50, 51, 52 und 53 ab. Mit diesen Fortsätzen 50, 51, 52 und 53 untergreift der Verstellrahmen 38 die beiden parallel zur Schwenkachse 26 des Folienmesserrahmens 21 verlaufenden Rahmenabschnitte 24 und 25 des Folienmesserrahmens 21.In a plan view of the foil knife frame 21 and the adjustment frame 38, the adjustment frame 38 lies essentially within the foil knife frame 21. From the adjustment frame 38, namely from its end walls 39 and 40, four are arranged in pairs in opposite directions from the pivot axis 43 of the adjustment frame 38 extensions 50, 51, 52 and 53 directed away from the adjustment frame. With these extensions 50, 51, 52 and 53, the adjustment frame 38 engages under the two frame sections 24 and 25 of the film knife frame 21 which run parallel to the pivot axis 26 of the film knife frame 21.

Mit der Schiebetaste 35 zum Verstellen des Folienmesserrahmens 21 ist ein Verstellhebel 54 der Verstelleinrichtung 36 über ein Gelenk 55 gelenkig verbunden. Der Verstellhebel 54 ist seinerseits mit dem Verstellrahmen 38 der Verstelleinrichtung 36 ebenfalls gelenkig verbunden. Hierfür ist der Verstellhebel 54 an seinem dem Verstellrahmen 38 benachbarten Ende gabelförmig ausgebildet, wobei im Bereich jeder der beiden Endabschnitte 56 und 57 des Verstellhebels 54 eine Bohrung vorgesehen ist, in die ein von der betreffenden Stirnwand 39 bzw. 40 des Verstellrahmens 38 abstehender Kupplungsstift 58 bzw. 59 zur Bildung einer Gelenkverbindung hineinragt. Die Schiebetaste 35 ist mit einem Schieber 60 verbunden, der im Gehäuse 5 verschiebbar geführt ist und der über das Gelenk 55 einstückig mit dem Verstellhebel 54 verbunden ist, wobei das Gelenk 55 durch ein Filmscharnier gebildet ist.An adjusting lever 54 of the adjusting device 36 is connected in an articulated manner by means of a joint 55 with the sliding button 35 for adjusting the foil knife frame 21. The adjusting lever 54 is in turn also articulated to the adjusting frame 38 of the adjusting device 36. For this purpose, the adjusting lever 54 is fork-shaped at its end adjacent to the adjusting frame 38, a bore being provided in the region of each of the two end sections 56 and 57 of the adjusting lever 54, into which a coupling pin 58 projecting from the relevant end wall 39 or 40 of the adjusting frame 38 or 59 protrudes to form an articulated connection. The sliding button 35 is connected to a slide 60 which is guided in the housing 5 and which is integrally connected to the adjusting lever 54 via the joint 55, the joint 55 being formed by a film hinge.

Durch das Vorsehen der Handhabe, also der Schiebetaste, zum Verstellen der Siebscherfolie am Gehäuse des Rasiergerätes ist eine einfache und bequeme Handhabung des Rasiergerätes beim Betätigen der Schiebetaste gewährleistet und kann die Schiebetaste relativ groß und handlich ausgebildet werden und können mit der Schiebetaste leicht und einfach zusätzliche Betriebsfunktionen, wie das Ein- und Ausschalten des Motors des Rasiergerätes, gesteuert werden. Darüberhinaus ist bei dem vorstehend beschriebenen Rasiergerät infolge der Ausbildung der Verstelleinrichtung für den Folienmesserrahmen in Form von einem Verstellrahmen zusätzlich erreicht, daß ein besonders einfaches und betriebssicheres Koppeln der Verstelleinrichtung mit dem Folienmesserrahmen durch das Untergreifen des Folienmesserrahmens mit dem Verstellrahmen beim Aufsetzen des Scherkopfrahmens auf das Gehäuse des Rasiergerätes und ein besonders gutes und sicheres Verschwenken des Folienmesserrahmens mit dem Verstellrahmen erreicht wird, wobei mit dem Verstellrahmen ein hinsichtlich der angreifenden Verstellkräfte vorteilhafterweise gleichmäßig verteiltes Angreifen am Folienmesserrahmen erfolgt. Auch ist bei dem beichriebenen Rasiergerät ein besonders einfaches Entkoppeln des Folienmesserrahmens und der Verstelleinrichtung für den Folienmesserrahmen beim Abnehmen des Scherkopfrahmens erreicht, weil hierbei lediglich der Folienmesserrahmen von dem ihn untergreifenden Verstellrahmen wegverstellt wird, ohne daß formschlüssige Verbindungen zwischen den beiden Rahmen gelöst werden müssen. Bei dem beschriebenen Rasiergerät ist weiters vorteilhafterweise erreicht, daß beim Abnehmen des Scherkopfrahmens die momentan eingestellte Position des Verstellrahmens erhalten bleibt, so daß bei einem neuerlichen Aufsetzen des Scherfkopfrahmens auf das Gehäuse des Gerätes der Folienmesserrahmen von dem Verstellrahmen automatisch in seine vor dem Abnehmen des Scherkopfrahmens gewählte Position verschwenkt wird.The provision of the handle, i.e. the sliding button, for adjusting the screen shaving foil on the housing of the shaving device ensures simple and convenient handling of the shaving device when the sliding button is pressed, and the sliding button can be made relatively large and handy and can be easily and simply added with the sliding button Operating functions, such as switching the shaver motor on and off, can be controlled. In addition, in the razor described above, due to the design of the adjustment device for the foil knife frame in the form of an adjustment frame additionally achieves that a particularly simple and reliable coupling of the adjusting device to the foil knife frame by reaching under the foil knife frame with the adjustment frame when the shaving head frame is placed on the housing of the razor and a particularly good and safe pivoting of the foil knife frame with the Adjusting frame is reached, with the adjusting frame advantageously engaging evenly distributed on the foil knife frame with regard to the attacking adjusting forces. Also a particularly simple decoupling of the foil knife frame and the adjustment device for the foil knife frame when removing the shaving head frame is achieved in the described shaving device, because here only the foil knife frame is moved away from the adjustment frame under it without having to release positive connections between the two frames. In the shaving apparatus described, it is also advantageously achieved that when the shaving head frame is removed, the position of the adjusting frame currently set is retained, so that when the shaving head frame is placed on the housing of the device again, the foil knife frame is automatically selected by the adjusting frame into its before the shaving head frame was removed Position is pivoted.

Die Erfindung ist auf das vorstehend beschriebene Ausführungsbeispiel nicht beschränkt. Beispielweise kann eine Siebscherfolie auch drei hinsichtlich der Haardurchtrittsöffnungen unterschiedliche Lochfelder aufweisen, wobei dann der eine solche Siebscherfolie tragende Folienmesserrahmen mit Hilfe eines Verstellrahmens in drei unterschiedliche Betriebspositionen verstellt wird. Auch kann der Verstellrahmen eine konstruktiv andere Ausbildung als bei dem vorstehend beschriebenen Ausführungsbeispiel aufweisen. Weiters stehen auch für die konstruktive Ausbildung der Verbindung zwischen der Handhabe zum Verstellen des Folienmesserrahmens und dem Verstellrahmen andere Möglichkeiten offen.The invention is not restricted to the exemplary embodiment described above. For example, a sieve shear foil can also have three perforated fields which are different with regard to the hair passage openings, in which case the foil knife frame carrying such a sieve shear foil is then adjusted to three different operating positions with the aid of an adjustment frame. The adjustment frame can also have a different construction than in the exemplary embodiment described above. Furthermore, there are other possibilities for the constructive design of the connection between the handle for adjusting the foil knife frame and the adjusting frame.
