Ein Rasierapparat gemäß der im vorstehend angeführten ersten Absatz Klassifizierten Gattung ist beispielsweise aus der JP 61-59.155 B2 bekannt. Der bekannte Rasierapparat weist eine verschwenkbare Zahnschneideinrichtung auf, die bei Betätigung einer als Schiebetaste ausgebildeten Handhabe zwischen zwei Schwenkpositionen verschwenkbar ist. Dabei besteht die Koppelungseinrichtung aus einem mit der Schiebetaste verbundenen Koppelungsschieber und einem von dem Koppelungsschieber steuerbaren und verstellbaren zweiarmigen Koppelungshebel, der unter der Wirkung einer Schenkelfeder der Koppelungseinrichtung steht, die einen Hebelarm des Koppelungshebels mit einem vom Koppelungsschieber abstehenden Koppelungsansatz in Wirkverbindung hält, und der mit einem vom anderen Hebelarm seitlich abstehenden Koppelungsstift in einen gabelartigen Bereich des Messerträgers der Zahnschneideinrichtung eingreift. Insgesamt weist somit die Koppelungseinrichtung eine aus mehreren Teilen bestehende, relativ aufwendige Ausbildung auf, was hinsichtlich einer möglichst einfachen und preiswerten Ausbildung des Rasierapparates und einer möglichst hohen Betriebssicherheit und einer möglichst raumsparenden Realisierung der Koppelungseinrichtung ungünstig ist.A shaver according to the type classified in the first paragraph mentioned above is known for example from JP 61-59.155 B2. The known shaving apparatus has a pivotable tooth cutting device which can be pivoted between two pivot positions when a handle designed as a sliding button is actuated. The coupling device consists of a coupling slide connected to the sliding button and a two-armed coupling lever which is controllable and adjustable by the coupling slide and which is under the action of a leg spring of the coupling device which has a lever arm of the coupling lever with a coupling projection protruding from the coupling slide Active connection holds, and which engages with a coupling pin projecting laterally from the other lever arm in a fork-like area of the knife carrier of the tooth cutting device. Overall, the coupling device thus has a relatively complex design consisting of several parts, which is disadvantageous with regard to the simplest and inexpensive design of the shaving apparatus and the highest possible operational reliability and a space-saving implementation of the coupling device.

Die Erfindung hat sich zur Aufgabe gestellt, bei einem Rasierapparat der im ersten Absatz angeführten Gattung die vorstehend erlauterten Schwierigkeiten zu beseitigen und bei einem solchen Rasierapparat eine möglichst einfache und preiswerte Ausbildung desselben zu erhalten und eine möglichst einfache und kompakte sowie betriebssichere Koppelungseinrichtung zu realisieren. Hierfür ist die Erfindung dadurch gekennzeichnet, daß die Koppelungseinrichtung durch einen einzigen sich über den Ubergangswandabschnitt der abgewinkelt ausgebildeten Seitenwand erstreckenden, korrespondierend zur Krümmung des Ubergangswandabschnittes flexiblen Koppelungsteil gebildet ist, der einerseits mit der Handhabe und andererseits mit dem Messerträger verbunden ist.The invention has set itself the task of eliminating the difficulties explained above in a shaver of the type mentioned in the first paragraph and to obtain the simplest and cheapest possible training of the same with such a shaver and to implement a coupling device that is as simple and compact as possible and reliable. For this purpose, the invention is characterized in that the coupling device is formed by a single coupling part, which extends over the transition wall section of the angled side wall and corresponds to the curvature of the transition wall section, and which is connected on the one hand to the handle and on the other hand to the knife carrier.

Auf diese Weise ist eine besonders einfache, raumsparende und betriebssichere Koppelungseinrichtung erhalten. Dies ist im Hinblick auf eine möglichst einfache und preiswerte Ausbildung eines solchen Rasierapparates und im Hinblick auf eine möglichst hohe Betriebssicherheit der Koppelungseinrichtung vorteilhaft. Dabei ist weiters der Vorteil einer an den Verlauf der Abwinkelung der abgewinkelt ausgebildeten Seitenwand optimal angepaßten Ausbildung der Koppelungseinrichtung erreicht.In this way, a particularly simple, space-saving and reliable coupling device is obtained. This is advantageous with regard to the simplest and inexpensive design of such a shaving apparatus and with regard to the highest possible operational reliability of the coupling device. The advantage of a design of the coupling device which is optimally adapted to the course of the bending of the angled side wall is also achieved.

Der flexible Koppelungsteil kann beispielsweise durch einen blattfederartigen Metallteil oder Kunststoffteil gebildet sein. Als besonders vorteilhaft hat sich aber erwiesen, wenn der Koppelungsteil jalousieartig ausgebildet ist und aus gelenkig miteinander verbundenen, quer zur Verstellrichtung des Koppelungsteiles verlaufenden Stegen besteht, die im Bereich ihrer beiden freien Enden in gehäuseseitige Führungsnuten ragen.The flexible coupling part can be formed, for example, by a leaf spring-like metal part or plastic part. However, it has proven to be particularly advantageous if the coupling part is designed in the manner of a blind and consists of webs which are connected to one another in an articulated manner and extend transversely to the direction of adjustment of the coupling part and which project in the region of their two free ends into guide grooves on the housing side.

Dies ist im Hinblick auf eine in Richtung der Stege möglichst stabile, gegen Eindrücken sichere Ausbildung des Koppelungsteiles vorteilhaft.This is advantageous with regard to a design of the coupling part which is as stable as possible in the direction of the webs and is secure against being pressed in.

Die Handhabe kann beispielsweise an einer anderen Seitenwand als die Zahnschneideinrichtung vorgesehen sein, beispielsweise an jener Seitenwand, die der Seitenwand gegenüberliegt, gegenüber der die Zahnschneideinrichtung verstellbar ist. Als besonders vorteilhaft hat sich aber erwiesen, wenn die Zahnschneideinrichtung einen im wesentlichen parallel zum ersten Wandabschnitt verstellbar geführten Messerträger aufweist und der Messerträger der Zahnschneideinrichtung, der flexible Koppelungsteil und die Handhabe als einstückiger Kunststoffteil ausgebildet sind. Dies ist im Hinblick auf eine besonders einfache Ausbildung vorteilhaft.The handle can, for example, on a different side wall than that Tooth cutting device may be provided, for example on that side wall which is opposite the side wall against which the tooth cutting device is adjustable. It has proven to be particularly advantageous, however, if the tooth cutting device has a knife carrier which is guided so as to be adjustable essentially parallel to the first wall section and the knife carrier of the tooth cutting device, the flexible coupling part and the handle are designed as a one-piece plastic part. This is advantageous with regard to a particularly simple training.

Die Abdeckung 7 dient zum Abdecken einer in Fig. 1 nicht sichtbaren Zahnschneideinrichtung 8, die zwischen einer in Fig. 1 und im Teil A der Fig. 3 dargestellten Ruheposition und einer im Teil B der Fig. 3 dargestellten Betriebsposition verstellbar ist. Die Ausbildung der Zahnschneideinrichtung 8 ist nachfolgend anhand der Figuren 2 und 3 detailliert beschrieben. Das Gehäuse 2 des Rasierapparates 1 weist eine erste breite Seitenwand 9, eine zweite breite Seitenwand 10, eine erste schmale Seitenwand 11 und eine zweite schmale Seitenwand 12, welche beiden schmalen Seitenwände 11 und 12 von der die beiden Gehäusehalbschalen 3 und 4 trennenden Trennzone geteilt sind, sowie eine im wesentlichen durch die Verschlußschale 4 gebildete Bodenwand 13 auf.1 shows a shaving apparatus 1, the housing 2 of which consists of a first housing half-shell 3, a second housing half-shell 4, a closure shell 5 holding the two housing half-shells 3 and 4 together at their foot-side end, and one in the head region 6 of the two housing half-shells 3 and 4 the first housing half-shell 3 consists of a cover 7 connected by a snap connection. The cover 7 serves to cover a tooth cutting device which is not visible in FIG. 1 8, which is adjustable between a rest position shown in FIG. 1 and in part A of FIG. 3 and an operating position shown in part B of FIG. 3. The design of the tooth cutting device 8 is described in detail below with reference to FIGS. 2 and 3. The housing 2 of the shaving apparatus 1 has a first wide side wall 9, a second wide side wall 10, a first narrow side wall 11 and a second narrow side wall 12, which two narrow side walls 11 and 12 are divided by the separation zone separating the two housing half-shells 3 and 4 , and a bottom wall 13 formed essentially by the closure shell 4.

In dem Kopfbereich 6 des Gehäuses 2 ist auf dasselbe ein Scherkopf 14 aufgesetzt, der in bekannter Weise eine Siebscherfolie als Obermesser und ein mit der Siebscherfolie zusammenwirkendes Untermesser aufweist, welche beiden Messer in den Figuren nicht dargestellt sind. Zum Abdecken der Siebscherfolie weist der Rasierapparat 1 einen Rolladen 15 auf, der aus einer die Siebscherfolie uberdeckenden Schutzposition in eine die Siebscherfolie freigebende Freigabeposition und umgekehrt verstellbar ist. Zum Verstellen des Rolladens 15 ist derselbe an seinem von der Siebscherfolie abgewandten Ende mit einer Handhabe 16 versehen, die im Teil A der Fig. 3 dargestellt ist.In the head region 6 of the housing 2, a shaving head 14 is placed thereon, which in a known manner has a screen shaving foil as the upper knife and a bottom knife interacting with the screen shaving foil, both knives not being shown in the figures. To cover the screen shaving foil, the shaving apparatus 1 has a roller shutter 15, which can be adjusted from a protective position covering the screen shaving foil into a release position releasing the screen shaving foil and vice versa. To adjust the roller shutter 15, it is provided at its end facing away from the screen shear film with a handle 16, which is shown in part A of FIG. 3.

Der Scherkopf 14 ist bei in seine Freigabeposition verstelltem Rolladen 15 von dem Gehäuse 2 des Rasierapparates 1 abnehmbar und auf das Gehäuse 2 aufsetzbar.The shaving head 14 can be removed from the housing 2 of the shaving apparatus 1 when the roller shutter 15 is in its release position and can be placed on the housing 2.

Um beim Aufsetzen des Scherkopfes 14 auf das Gehäuse 2 des Rasierapparates 1 eine gute Positionierung des Scherkopfes 14 gegenüber dem Gehäuse 2 des Rasierapparates 1 zu erzielen, weist der Scherkopf 14 an seinen beiden schmalen Endbereichen je einen Führungslappen 17 auf, der beim Aufsetzen des Scherkopfes 14 auf das Gehäuse 2 des Rasierapparates 1 in eine zwischen den beiden Gehäusehalbschalen 3 und 4 freigelassene Führungsausnehmung 18 eintritt und der bei vollständig auf das Gehäuse 2 aufgesetztem Scherkopf 14 von der Führungsausnehmung 18 positioniert wird. Jedem der beiden Führungslappen 17 liegt an seinem gegenüber dem Scherkopf 14 freien Ende 19 ein im wesentlichen quer zu den schmalen Seitenwänden 11 und 12 verstellbarer Entriegelungsknopf 20 gegenüber, durch dessen Verstellung quer zu den schmalen Seitenwänden 11 und 12 eine Entriegelung des Scherkopfes 14 eifolgt, so daß nach einer solchen Entriegelung der Scherkopf 14 vom Gehäuse 2 des Rasierapparates 1 abgenommen werden kann.In order to achieve a good positioning of the shaving head 14 relative to the housing 2 of the shaving apparatus 1 when the shaving head 14 is placed on the housing 2 of the shaving apparatus 1, the shaving head 14 has a guide tab 17 on each of its two narrow end regions, which tabs 14 are attached when the shaving head 14 is placed on enters the housing 2 of the shaving apparatus 1 into a guide recess 18 left free between the two housing half-shells 3 and 4 and which is positioned by the guide recess 18 when the shaving head 14 is completely placed on the housing 2. Each of the two guide tabs 17 is located at its free end 19, opposite the shaving head 14, with an unlocking button 20 which is adjustable essentially transversely to the narrow side walls 11 and 12, by means of whose adjustment transversely to the narrow side walls 11 and 12 an unlocking of the shaving head 14 follows that after such unlocking the shaving head 14 can be removed from the housing 2 of the shaver 1.

Wie aus der Fig. 1 ersichtlich ist, sind bei dem Rasierapparat 1 sowohl die erste breite Seitenwand 9 als auch die zweite breite Seitenwand 10 des Gehäuses 2 je in einem an den Kopfbereich 6 angrenzenden Bereich 21 abgewinkelt ausgebildet. Die erste breite Seitenwand 9 weist hierbei einen in den Kopfbereich 6 mündenden ersten Wandabschnitt 22 auf, der mit der Abdeckung 7 des Gehäuses 2 abgedeckt ist. Weiters weist die erste breite Seitenwand 9 einen in das fußseitige Gehäuseende mündenden zweiten Wandabschnitt 23 auf. Der erste Wandabschnitt 22 und der zweite Wandabschnitt 23 der ersten breiten Seitenwand 9 schließen einen stumpfen Winkel miteinander ein. Hierbei sind der erste Wandabschnitt 22 und der zweite Wandabschnitt 23 über einen entsprechend der Abwinkelung der ersten breiten Seitenwand 9 gekrümmt verlaufenden Übergangswandabschnitt 24 miteinander verbunden.As can be seen from Fig. 1, both in the shaver 1 The first wide side wall 9 and the second wide side wall 10 of the housing 2 are each angled in an area 21 adjoining the head area 6. The first wide side wall 9 has a first wall section 22 opening into the head region 6, which is covered with the cover 7 of the housing 2. Furthermore, the first wide side wall 9 has a second wall section 23 opening into the foot end of the housing. The first wall section 22 and the second wall section 23 of the first wide side wall 9 form an obtuse angle with one another. In this case, the first wall section 22 and the second wall section 23 are connected to one another via a transition wall section 24 which runs curved in accordance with the angle of the first wide side wall 9.

Infolge der Abwinkelung der ersten breiten Seitenwand 9 und der zweiten breiten Seitenwand 10 ist der Scherkopf 14 bei dem Rasierapparat 1 gegenüber dem vom Kopfbereich 6 abgewandten Bereich 25 des Gehäuses 2 geneigt angeordnet. Eine solche geneigte Anordnung des Scherkopfes 14 ist im Hinblick auf eine möglichst bequeme Handhabung des Rasierapparates 1 vorteilhaft, da im Betrieb des Rasierapparates 1 das Gehäuse 2 in dem Bereich 25 in einer Hand gehalten wird, wobei dann der Scherkopf 14 in Richtung zum Gesicht des Benutzers des Rasierapparates 1 hin abgewinkelt positioniert ist, was eine sehr bequeme Handhabung ermöglicht.As a result of the angling of the first wide side wall 9 and the second wide side wall 10, the shaving head 14 in the shaving apparatus 1 is arranged inclined relative to the area 25 of the housing 2 facing away from the head area 6. Such an inclined arrangement of the shaving head 14 is advantageous in terms of handling the shaving apparatus 1 as conveniently as possible, since in the operation of the shaving apparatus 1 the housing 2 is held in one hand, the shaving head 14 then facing the face of the user of the shaver 1 is positioned angled, which enables very convenient handling.

Im Hinblick auf eine möglichst bequeme Handhabung hat sich hierbei als zweckmäßig erwiesen, wenn die Zahnschneideinrichtung 8 in ihrer Betriebsposition möglichst nahe beim Scherkopf 14 bzw. bei der Siebscherfolie des Scherkopfes 14 zu liegen kommt. Um dies zu gewährleisten, ist bei dem vorliegenden Rasierapparat 1 die Zahnschneideinrichtung 8 im Bereich des ersten Wandabschnittes 22 der ersten breiten Seitenwand 9 des Gehäuses 2 angeordnet und gegenüber dem ersten Wandabschnitt 22 zwischen der im Teil A der Fig.3 dargestellten Ruheposition und der im Teil B der Fig.3 dargestellten Betriebsposition verstellbar.With regard to handling that is as convenient as possible, it has proven to be expedient if the tooth cutting device 8 comes to lie as close as possible to the shaving head 14 or the shaving foil of the shaving head 14 in its operating position. To ensure this, in the present shaving apparatus 1, the tooth cutting device 8 is arranged in the region of the first wall section 22 of the first wide side wall 9 of the housing 2 and opposite the first wall section 22 between the rest position shown in part A of FIG. 3 and that in the part B of the operating position shown in Figure 3 adjustable.

Wie aus den Figuren 2 und 3 ersichtlich ist, weist die Zahnschneideinrichtung 8 einen Messerträger 26 auf, der gegenüber dem ersten Wandabschnitt 22 der ersten breiten Seitenwand 9 der ersten Gehäusehalbschale 3 in Richtung des Doppelpfeiles 27 verschiebbar geführt ist.As can be seen from FIGS. 2 and 3, the tooth cutting device 8 has a knife carrier 26 which is displaceably guided in the direction of the double arrow 27 relative to the first wall section 22 of the first wide side wall 9 of the first housing half-shell 3.

Zür Führung des Messerträgers 26 weist die erste Gehäusehalbschale 3 im Bereich ihres ersten Wandabschnittes 22 zwei von dieser abstehende, L-förmig ausgebildete Führungsleisten 28 und 29 auf, die je mit einer vom Messerträger 26 seitlich abstehenden einfachen Führungsleiste 30 zusammenwirken, von denen in Fig.2 nur eine sichtbar ist. Hierbei ist in eine im Bereich des ersten Wandabschnittes 22 der ersten Gehäusehalbschale 3 vorgesehene Aufnahmekammer 31 eine Blattfeder 32 eingesetzt, die mit ihrem gebogen ausgebildeten Mittenbereich gegen die Innenseite des Messerträgers 26 drückt, wodurch die Führungsleisten 30 gegen die abgewinkelten Bereiche der L-förmigen Führungsleisten 28 und 29 gedrückt werden, die hierbei den Messerträger 26 an den ersten Wandabschnitt 22 angrenzend positioniert halten. Durch das Vorsehen der Blattfeder 32 wird das Führungsspiel quer zu dem ersten Wandabschnitt 22 beseitigt. Zur Führung des Messerträgers 26 in Richtung des Doppelpfeiles 27 sind weiters zwei von dem ersten Wandabschnitt 22 senkrecht abstehende Führungsleisten 33 und 34 vorgesehen, zwischen die ein von dem Messerträger 26 an dessen Innenseite abstehender, in Fig.2 nicht sichtbarer Führungsstift ragt. Weiters sind zur Führung des Messerträgers 26 zwei von dem ersten Wandabschnitt 22 senkrecht abstehende Führungsleisten 35 und 36 vorgesehen, mit denen zwei von dem Messerträger 26 seitlich abstehende federnde Führungsarme 37 und 38 zusammenwirken. Hierbei sind die freien Enden der Führungsarme 37 und 38 als Rastnocken 39 und 40 ausgebildet, die in Rastvertiefungen 41 bzw. 42 und 43 bzw. 44 einrasten können, und zwar entsprechend der Ruheposition bzw. der Betriebsposition der Zahnschneideinrichtung 8.The guidance of the knife carrier 26 has the first housing half-shell 3 in the region of its first wall section 22 two L-shaped guide strips 28 and 29 protruding therefrom, each with one laterally from the knife carrier 26 protruding simple guide bar 30 cooperate, of which only one is visible in Figure 2. In this case, a leaf spring 32 is inserted into a receiving chamber 31 provided in the region of the first wall section 22 of the first housing half-shell 3, which, with its curved central region, presses against the inside of the knife carrier 26, as a result of which the guide strips 30 press against the angled regions of the L-shaped guide strips 28 and 29 are pressed, which in this case hold the knife carrier 26 positioned adjacent to the first wall section 22. The provision of the leaf spring 32 eliminates the guide play transverse to the first wall section 22. To guide the knife carrier 26 in the direction of the double arrow 27, two guide strips 33 and 34 projecting vertically from the first wall section 22 are also provided, between which a guide pin, not visible in FIG. 2, protrudes from the knife carrier 26 on the inside thereof. Furthermore, two guide strips 35 and 36 projecting perpendicularly from the first wall section 22 are provided for guiding the knife carrier 26, with which two resilient guide arms 37 and 38 projecting laterally from the knife carrier 26 cooperate. Here, the free ends of the guide arms 37 and 38 are designed as locking cams 39 and 40, which can snap into locking recesses 41 or 42 and 43 or 44, in accordance with the rest position or the operating position of the tooth cutting device 8.

Mit Hilfe der Führungsarme 37 und 38 wird das Führungsspiel parallel zu dem ersten Wandabschnitt 22 und quer zur Verstellrichtung 27 des Messerträgers 26 beseitigt.With the help of the guide arms 37 and 38, the guide play is eliminated parallel to the first wall section 22 and transversely to the adjustment direction 27 of the knife carrier 26.

Auf dem Messerträger 26 sind ein im Betrieb stillstehendes erstes Zahnmesser 45 und ein mit diesem zusammenwirkendes, im Betrieb hin- und hergehend antreibbares zweites Zahnmesser 46 angebracht. Das stillstehende erste Zahnmesser 45 ist hierbei auf den Messerträger 26 aufgeschnappt. Das antreibbare zweite Zahnmesser 46 ist auf eine Antriebsbrücke 47 aufgeschnappt, die an dem stillstehenden ersten Zahnmesser 45 hin- und hergehend verstellbar geführt ist und an der zwei Andruckfedern 48 und 49 angreifen, die andererseits am Messerträger 26 abgestützt und gehalten sind.A first tooth knife 45 which is stationary during operation and a second tooth knife 46 which interacts with it and can be driven back and forth during operation are attached to the knife carrier 26. The stationary first tooth knife 45 is snapped onto the knife carrier 26. The drivable second tooth knife 46 is snapped onto a drive bridge 47, which is guided to and fro in an adjustable manner on the stationary first tooth knife 45 and on which two pressure springs 48 and 49 act, which on the other hand are supported and held on the knife carrier 26.

Die Andruckfedern 48 und 49 drücken die Zahnreihe des antreibbaren Zahnmessers 46 gegen die Zahnreihe des stillstehenden Zahnmessers 45, um eine elnwandfreie Schneidfunktion zu gewährleisten. Die Antriebsbrücke 47 weist zwei Fortsätze 50 und 51 auf, die einen Zwischenraum einschließen, in den das abgerundete Ende 52 eines Antriebshebels 53 hineinragt, der an dem Messerträger 26 schwenkbar gelagert ist. Zum Sichern des Antriebshebels 53 an dem Messerträger 26 ist eine Abdeckung 54 vorgesehen, die mit dem Messerträger 26 verbunden ist. An seinem vom abgerundeten Ende 52 abgewandten Ende 55 weist der Antriebshebel 53 eine Antriebsnut 56 auf, in die bei in ihre Betriebsposition verstellter Zahnschneideinrichtung 8 ein Antriebsstift 57 zum Antreiben des Antriebshebels 53 ragt, wie dies im Teil B der Fig.3 dargestellt ist. Der Antriebsstift 57 ragt hierbei durch ein Fenster 58 im ersten Wandabschnitt 22 der ersten breiten Seitenwand 9 der ersten Gehäusehalbschale 3.The pressure springs 48 and 49 press the tooth row of the drivable tooth knife 46 against the tooth row of the stationary tooth knife 45 in order to ensure a wall-free cutting function. The drive bridge 47 has two extensions 50 and 51, which enclose an intermediate space into which the rounded end 52 of a drive lever 53 projects, which is pivotably mounted on the knife carrier 26. To secure the drive lever 53 to the knife carrier 26, a cover 54 is provided which is connected to the knife carrier 26. At its end 55 facing away from the rounded end 52, the drive lever 53 has a drive groove 56 into which a drive pin 57 for driving the drive lever 53 projects when the tooth cutting device 8 is in its operating position, as is shown in part B of FIG. The drive pin 57 projects through a window 58 in the first wall section 22 of the first wide side wall 9 of the first housing half-shell 3.

Zum Verstellen des Messerträgers 26 bzw. der Zahnschneideinrichtung 8 in Richtung des Doppelpfeiles 27 weist der Rasierapparat 1 eine am Gehäuse 2 im Niveaubereich 25 des zweiten Wandabschnittes 23 der ersten breiten Seitenwand 9 verstellbar gehaltene, händisch betätigbare Handhabe 59 auf, bei deren Betätigung der Messerträger 26 verstellt wird. Die Handhabe 59 ist hierbei durch eine Leiste gebildet, die von einem quer zur Verstellrichtung 27 verlaufenden Steg 60 getragen ist. Zwischen der Handhabe 59 und dem Messerträger 26 ist eine Koppelungseinrichtung 61 vorgesehen, über die durch ihre Verstellung beim Betätigen der Handhabe 59 das Verstellen des Messerträgers 26 steuerbar ist.To adjust the knife carrier 26 or the tooth cutting device 8 in the direction of the double arrow 27, the shaving apparatus 1 has a manually operable handle 59 on the housing 2 in the level region 25 of the second wall section 23 of the first wide side wall 9, when the knife carrier 26 is actuated is adjusted. The handle 59 is in this case formed by a strip which is supported by a web 60 extending transversely to the adjustment direction 27. A coupling device 61 is provided between the handle 59 and the knife carrier 26, by means of which the adjustment of the knife carrier 26 can be controlled by its adjustment when the handle 59 is actuated.

Bei dem vorliegenden Rasierapparat 1 ist nunmehr die Koppelungseinrichtung 61 auf besonders einfache, raumsparende und betriebssichere und daher vorteilhafte Weise durch einen einzigen sich über den Übergangswandabschnitt 24 der abgewinkelt ausgebildeten ersten breiten Seitenwand 9 erstreckenden, korrespondierend zur Krümmung des Übergangswandabschnittes 24 flexiblen Koppelungsteil gebildet, der einerseits über den Steg 60 mit der Handhabe 59 und andererseits mit dem Messerträger 26 verbunden ist. Dabei ist der Koppelungsteil 61 jalousieartig ausgebildet und besteht der Koppelungsteil 61 aus über Gelenke 62 gelenkig miteinander verbundenen, quer zur Verstellrichtung 27 des Koppelungsteiles 61 verlaufenden Stegen 63, die im Bereich ihrer beiden freien Enden in gehäuseseitige Führungsnuten 64 ragen, und zwar mit von den Stegen 63 seitlich abstehenden Führungsstiften 65. Solche Führungsstifte 66 stehen auch von dem die Handhabe 59 tragenden Steg 60 seitlich ab. Der Messerträger 26 der Zahnschneideinrichtung 8, der flexible Koppelungsteil 61 und die Handhabe 59 samt dem Steg 60 sind hierbei als einstückiger Kunststoffteil ausgebildet, wobei die Gelenke 62 zwischen den Stegen 63 als Filmscharniere ausgebildet sind.In the present shaving apparatus 1, the coupling device 61 is now formed in a particularly simple, space-saving and reliable and therefore advantageous manner by a single coupling part, which extends over the transition wall section 24 of the angled first wide side wall 9 and corresponds to the curvature of the transition wall section 24 is connected via the web 60 to the handle 59 and on the other hand to the knife carrier 26. The coupling part 61 is designed in the manner of a blind and the coupling part 61 consists of webs 63 which are articulated to one another via joints 62 and extend transversely to the adjustment direction 27 of the coupling part 61 and project in the region of their two free ends into guide grooves 64 on the housing, namely from the webs 63 laterally protruding guide pins 65. Such guide pins 66 also protrude laterally from the web 60 carrying the handle 59. The knife carrier 26 of the tooth cutting device 8, the flexible coupling part 61 and the handle 59 together with the web 60 are designed as a one-piece plastic part, the joints 62 between the webs 63 being designed as film hinges.

Durch die vorstehend beschriebene Ausbildung ist eine besonders einfache, raumsparende und betriebssichere Koppelungseinrichtung realisiert, was hinsichtlich einer möglichst einfachen und preiswerten Ausbildung eines solchen Rasierapparates und hinsichtlich einer möglichst hohen Betriebssicherheit und einer möglichst raumsparenden Realisierung der Koppelungseinrichtung vorteilhaft ist.A particularly simple, space-saving and reliable coupling device is realized by the above-described design, which is advantageous with regard to the simplest and inexpensive design of such a shaving apparatus and with regard to the highest possible operational reliability and a space-saving implementation of the coupling device.

Weiters ist hierdurch der Vorteil einer an den Verlauf der Abwinkelung der abgewinkelt ausgebildeten, die Zahnschneideinrichtung tragenden Seitenwand optimal und mit minimalem Raumbedarf angepaßten Ausbildung der Koppelungseinrichtung erreicht. Durch die Ausbildung der Koppelungseinrichtung als jalousieartiger Koppelungsteil, der aus gelenkig miteinander verbundenen, quer zur Verstellrichtung des Koppelungsteiles verlaufenden und quer zur Verstellrichtung relativ steifen Stegen besteht, ist weiters erreicht, daß der Koppelungsteil gegen Eindrücken eine relativ große Widerstandskraft aufweist.Furthermore, the advantage of a design of the coupling device which is adapted to the course of the angling of the angled side wall carrying the tooth cutting device is achieved optimally and with a minimal space requirement. By designing the coupling device as a louvre-like coupling part, which consists of articulated interconnected webs that run transversely to the direction of adjustment of the coupling part and are relatively stiff transversely to the direction of adjustment, it is further achieved that the coupling part has a relatively large resistance to being pressed in.

Durch die einstückige Ausbildung des Messerträgers, des Koppelungsteiles und der Handhabe ist eine besonders einfache Ausbildung erhalten.The one-piece design of the knife carrier, the coupling part and the handle results in a particularly simple design.

Bezüglich der Fig.3 bleibt noch zu erwähnen, daß im Teil A der Fig.3 schematisch eine Motorhalterung 67 dargestellt ist, in der ein Motor 68 festgehalten ist, der eine Motorwelle 69 aufweist. Von der Motorwelle 69 ist eine nicht dargestellte, eine sogenannte Schwingbrücke aufweisende Antriebseinrichtung antreibbar, von der das mit der Siebscherfolie des Scherkopfes 14 zusammenwirkende Untermesser antreibbar ist. Von der Schwingbrücke der vorerwähnten Antriebseinrichtung steht seitlich der Antriebsstift 57 ab, mit dem der Antriebshebel 53 zum Antreiben des antreibbaren Zahnmessers 46 der Zahnschneideinrichtung 8 antreibbar ist.With regard to FIG. 3, it should also be mentioned that part A of FIG. 3 schematically shows a motor holder 67 in which a motor 68 is held, which has a motor shaft 69. A drive device (not shown), which has a so-called oscillating bridge, can be driven by the motor shaft 69 and the lower knife, which interacts with the screen shaving foil of the shaving head 14, can be driven by this drive device. The drive pin 57, with which the drive lever 53 can be driven to drive the drivable tooth knife 46 of the tooth cutting device 8, projects laterally from the swing bridge of the aforementioned drive device.

Wie aus dem Teil A der Fig.3 ersichtlich ist, besteht zwischen dem Antriebsstift 57 und dem Antriebshebel 53 keine Antriebsverbindung, wenn die Zahnschneideinrichtung 8 ihre Ruheposition einnimmt.As can be seen from part A of FIG. 3, there is no drive connection between the drive pin 57 and the drive lever 53 when the tooth cutting device 8 is in its rest position.

Durch Betätigen der Handhabe 59, und zwar durch Verschieben derselben entlang der ersten breiten Seitenwand 9, wird über den flexiblen Koppelungsteil 61 - der hierbei über den gekrümmt verlaufenden Übergangswandabschnitt 24 hinweg bewegt wird, wobei die gelenkig miteinander verbundenen Stege 63 gegenüber einander um die Filmscharniere 62 verschwenkt werden - der Messerträger 26 in Richtung des Doppelpfeiles 27 und somit die gesamte Zahnschneideinrichtung 8 in ihre Betriebsposition verstellt.By actuating the handle 59, namely by moving it along the first wide side wall 9, the flexible coupling part 61 - which in this case is moved over the curved transition wall section 24 - is moved, the articulated webs 63 being opposite one another around the film hinges 62 are pivoted - the knife carrier 26 is adjusted in the direction of the double arrow 27 and thus the entire tooth cutting device 8 into its operating position.

Sowohl die Handhabe 59 als auch die Zahnschneideinrichtung 8 werden dabei um einen Hub h verstellt, der in der Praxis beispielsweise 16 mm betragen kann.Both the handle 59 and the tooth cutting device 8 are adjusted by a stroke h, which in practice can be, for example, 16 mm.

Nach einer solchen Verstellung der Zahnschneideinrichtung 8 steht der Antriebsstift 57 mit dem Antriebshebel 53 in Antriebsverbindung, so daß dann das antreibbare Messer 46 der Zahnschneideinrichtung 8 angetrieben wird, wenn der Motor 68 eingeschaltet wird.After such an adjustment of the tooth cutting device 8, the drive pin 57 is in drive connection with the drive lever 53, so that the drivable knife 46 of the tooth cutting device 8 is then driven when the motor 68 is switched on.

Die Erfindung ist nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. Beispielsweise kann die Handhabe zum Verstellen der Zahnschneideinrichtung unmittelbar durch einen oder mehrere Stege des Koppelungsteiles gebildet sein. Anstelle eines jalousieartig ausgebildeten Koppelungsteiles mit gelenkig miteinander verbundenen Stegen kann auch ein aus einem blattfederartigen Metallteil oder Kunststoffteil gebildeter Koppelungsteil vorgesehen sein. Die Zahnschneideinrichtung kann nicht nur parallel zum ersten Wandabschnitt der abgewinkelt ausgebildeten Seitenwand verschiebbar sein, sondern sie kann zusätzlich gegenüber diesem ersten Wandabschnitt auch noch verschwenkbar sein bzw. kann die Zahnschneideinrichtung gegenüber dem ersten Wandabschnitt auch nur verschwenkbar angeordnet sein.The invention is not restricted to the exemplary embodiment described above. For example, the handle for adjusting the tooth cutting device can be formed directly by one or more webs of the coupling part. Instead of a louvre-like coupling part with articulated webs, a coupling part formed from a leaf spring-like metal part or plastic part can also be provided. The tooth cutting device can not only be displaceable parallel to the first wall section of the angled side wall, but it can also be pivotable with respect to this first wall section or the tooth cutting device can also be arranged only pivotable with respect to the first wall section.

Die Zahnschneideinrichtung kann aus einer Ruheposition auch in zwei unterschiedliche Betriebspositionen verstellbar sein. Die Handhabe zum Verstellen der Zahnschneideinrichtung muß nicht im Bereich jener Seitenwand angeordnet sein, in deren Bereich auch die Zahnschneideinrichtung angeordnet ist; diese Handhabe kann beispielsweise auch im Bereich der gegenüberliegenden breiten Seitenwand angeordnet sein, in deren Bereich beim vorstehend beschriebenen Rasierapparat die Handhabe zum Verstellen des die Siebscherfolie überdeckenden Rolladens angeordnet ist, oder auch im Bereich einer der beiden schmalen Seitenwände des Gehäuses des Rasierapparates.The tooth cutting device can also be adjustable from one rest position into two different operating positions. The handle for adjusting the tooth cutting device does not have to be arranged in the area of the side wall in the area of which the tooth cutting device is also arranged; this handle can, for example, also be arranged in the region of the opposite wide side wall, in the region of which the handle for adjusting the roller shutter covering the screen shaving foil is arranged in the shaving apparatus described above, or also in the region of one of the two narrow side walls of the housing of the shaving apparatus.
