Definitions
- the invention relates to a razor consisting of a razor blade unit, in which a razor blade is embedded in a plastic housing, and a handle, at the front end of which the razor blade unit by means of an openable and closable fork holder, starting from a spring-loaded zero position around the cutting edge of the razor blade parallel pivot axis is arranged below the plane of the razor blade and extends in the area of the cutting edge of the razor blade.
- a razor of this type is known, on the handle of which a razor blade unit is pivotably mounted at the front end by means of an openable and closable fork holder, starting from a spring-loaded zero position about a pivot axis parallel to the cutting edges of the razor blades.
- the swivel axis defined by the fork holder runs below the cutting edge of the front, lower razor blade of the double razor blade. This creates a torque during shaving that tries to turn the blades clockwise.
- This type of deflection can lead to an indifferent balance, since the forces that occur during shaving depend on various factors, for example on the individual guidance of the razor, the facial zone in which shaving is carried out, the individual beard thickness, the individual condition of the skin, the shaving aid used (soap, foam, etc.) and cleaning the blade under water while shaving.
- a razor is known, on the front end of which a razor blade unit is also pivotally mounted.
- the swivel axis runs approximately in the middle below the razor blades parallel to their cutting edges.
- a torque is generated during shaving, the deflection of which can lead to an indifferent balance.
- the object of the invention is to further develop the known razor in such a way that the pivoting position of the razor blade unit on the fork holder of the handle is improved.
- the invention proposes that the pivot axis runs in front of the cutting edge of the razor blade.
- a razor designed according to this technical teaching with a pivot axis running in front of the cutting edge of the razor blade has an optimal pivot bearing of the razor blade unit on the fork holder of the handle, so that the razor blade unit adapts exactly to the face contour during the shaving process.
- the torque occurring during the shaving process is minimal, so that the pivoting movements resulting from the torque during the shaving process are relatively small.
- the force is applied almost on the line of contact between the razor blade and the skin, so that there is no torque causing unwanted deflections within technically unavoidable limits. Overall, a stable system is obtained.
- the pivot axis of the fork holder preferably extends in the area of the cutting edge of the lower, front razor blade.
- the pivot axis is arranged below a front guide bar.
- the razor blade unit is mounted on the fork holder in the area of the side walls of the plastic housing. In this way, there is a storage lying far outside, which leads to a safe guidance.
- the fork holder is preferably designed as a spring mounted in the handle, in particular a wire spring, which has an actuation area for the fingers of the user to disengage the spring from the razor blade unit.
- This poses represents a technically very simple possibility for locking the handle with the razor blade unit, in particular thereby enabling simple one-hand operation by the user.
- this spring for the fork holder has a U-shaped base element, the front leg ends of which have fork arms lying in the plane of the base spring element and projecting outwards, which are engaged with their front ends in corresponding recesses in the razor blade unit and the bearing points define.
- the U-shaped base spring element enables a simple disengagement of the fork holder on the razor blade unit by pressing the legs of this base spring element together, so that the front ends of the fork arms pivot inwards.
- the front ends of the fork arms are each preferably S-shaped in the plane of the spring and form trunnions. This bend allows the fork holder of the handle to be inserted into the inside of the razor blade unit in a simple manner, so that the bearing points can be brought into close proximity to the foremost cutting edge in a technically very simple manner.
- the razor blade unit has a stop for the zero position corresponding to the fork holder, against which the zero position spring presses the razor blade unit and the razor blade unit can only be pivoted in one direction, preferably backwards, starting from this zero position.
- a U-shaped spring, a leaf spring, a leg spring or the like made of plastic or metal can be provided as the so-called zero-position spring.
- the zero-position spring is preferably arranged on the rear, upper end of the handle and is supported on the rear underside of the razor blade unit. In any case, this zero position spring presses the razor blade unit into the zero position position, from which the razor blade unit can only be pivoted in one direction.
- the swivel range of the razor blade unit is preferably 15 ° to 30 °.
- FIGS. 4 and 5 show a schematic sectional illustration of a complete shaving apparatus 2, in which the razor blade unit 1 from FIGS. 1 to 3 is attached to the front end of a handle 3. This handle 3 or parts thereof are shown in FIGS. 4 and 5.
- the razor blade unit 1 consists of a one-piece plastic housing 4. This has a front guide bar 5, two side walls 6 and a blade platform 7 on the inside.
- a double razor blade consisting of the two razor blades 8, 8 'is inserted from above through an opening 9 formed in the plastic housing 4.
- the two razor blades 8, 8 'on a flat, elongated, cuboid spacer 10 are so permanently attached that the spacer 10 is sandwiched between the two razor blades 8, 8'.
- the razor blades 8, 8 'and the spacer 10 thus form a so-called razor blade / spacer unit 11.
- the spacer 10 is somewhat longer than the two razor blades 8, 8', so that the spacer 10 slightly over the ends of the razor blades 8, 8 'survives.
- the blade platform 7 of the razor blade unit 1 has a recess 12 on both sides in the region of the side walls 6.
- the razor blade / spacer unit 11 is placed from above in the direction of arrow P in the plastic housing 4 on the blade platform 7. Subsequently, as can be seen in FIG. 2, the plastic housing 4 is wrapped with wire 13 together with the razor blades / spacer unit 11 used.
- a cap 14 with an essentially U-shaped cross-sectional profile is used for this purpose.
- the cap 14, which extends over the entire length of the plastic housing 4 has a latching device 15 on the upper side. This consists of end-side latch arms 16 which each have a latch 17 at their front ends. Corresponding to these locking lugs 17, the plastic housing 4 each has a locking recess 18.
- FIG. 3 Because the top of the cap 14 rests on the razor blade / spacer unit 11, the latter is fixed firmly on the blade platform 7 of the plastic housing 4.
- a handle 3 is provided for the razor blade unit 1. This has a special fork holder 19 at its front end, by means of which the handle 3 can be snapped into the razor blade unit 1.
- This fork holder 19 consists of a spring 20 in the form of a wire spring. This is shown in FIG. 4 on its own without the handle 3.
- This spring 20 initially consists of a U-shaped base spring element 21, the front leg ends of which are bent vertically outwards and form fork arms 22. The front ends of the fork arms 22 are bent in an S-shape and form bearing pins 23.
- FIG. 5 shows how the spring 20 of the fork holder 19 is arranged in the front area of the handle 3.
- the base of the U-shaped base spring element 21 is fixed within the handle 3 in such a way that the legs extend forward.
- the fork arms 22 come to lie in a T-shaped extension 24 of the handle 3.
- the legs of the basic spring element 21 are exposed in the front area.
- actuation areas B are formed so that the bearing pins 23 of the spring 20 can be pivoted inwards toward one another by compressing the legs of the base spring element 21. This is indicated by the arrows P ⁇ . After releasing the bearing pins 23 return to their starting position.
- a so-called zero-position spring 25 can be seen in FIGS. 4 and 5.
- this is designed as a leaf spring made of plastic or metal and is mounted with its lower end in the handle 3.
- it can also be designed as a U-spring, as a leg spring, etc.
- the technical meaning of the zero position spring 25 will be explained later with reference to FIG. 6.
- the journals 23 are first pivoted inward in the manner described.
- the fork holder 19 can be inserted into the razor blade unit 1, as can be seen in particular in FIGS. 3 and 6.
- the razor blade unit 1 is each provided in the region of its side walls 6 with a recess 26 into which the bearing pins 23 of the fork holder 19 engage after the spring 20 has been released.
- the pivot axis S defined by the bearing pin 23 lies in the region of the cutting edge 27 of the front razor blade 8, ie the pivot axis S runs in front of this cutting edge 27 parallel to it and somewhat offset below the plane of this front razor blade 8
- FIG. 1 the pivot axis S defined by the bearing pin 23 lies in the region of the cutting edge 27 of the front razor blade 8
- the pivot axis S runs in front of this cutting edge 27 parallel to it and somewhat offset below the plane of this front razor blade 8
- the zero-position spring 25 presses the razor blade unit 1 forward against a stop 28 inside the plastic housing 4. During the shaving process, the razor-blade unit 1 can thus only be pivoted backwards against the force of the zero-position spring 25, the pivoting range being between 15 ° and 30 °.

Description
Die Erfindung betrifft einen Rasierapparat bestehend aus einer Resierklingeneinheit, bei der eine Rasierklinge unlösbar in einem Kunststoffgehäuse eingebettet ist, sowie aus einem Handgriff, an dessen vorderem Ende die Rasierklingeneinheit mittels einer öffen- und schließbaren Gabelhalterung ausgehend von einer federbelasteten Nullage um eine zur Schneidkante der Rasierklinge parallele, unterhalb der Ebene der Rasierklinge angeordnete sowie im Bereich der Schneidkante der Rasierklinge sich erstreckende Schwenkachse verschwenkbar gelagert ist.The invention relates to a razor consisting of a razor blade unit, in which a razor blade is embedded in a plastic housing, and a handle, at the front end of which the razor blade unit by means of an openable and closable fork holder, starting from a spring-loaded zero position around the cutting edge of the razor blade parallel pivot axis is arranged below the plane of the razor blade and extends in the area of the cutting edge of the razor blade.
Aus der US-A-4514904 ist ein Rasierapparat dieser Art bekannt, an dessen Handgriff am vorderen Ende mittels einer öffen- und schließbaren Gabelhalterung eine Rasierklingeneinheit ausgehend von einer federbelasteten Nullage um eine zu den Schneidkanten der Rasierklingen parallele Schwenkachse verschwenkbar gelagert ist. Die durch die Gabelhalterung definierte Schwenkachse verläuft dabei unterhalb der Schneidkante der vorderen, unteren Rasierklinge der Doppelrasierklinge. Dadurch entsteht während der Rasur ein Drehmoment, welches die Klingen im Uhrzeigersinn zu drehen versucht. Diese Art der Auslenkung kann zu einem indifferenten Gleichgewicht führen, da die während der Rasur auftretenden Kräfte von verschiedenen Faktoren abhängig sind, beispielsweise von der individuellen Führung des Rasierapparates, der Gesichtszone, in der rasiert wird, der individuellen Bartstärke, der individuellen Beschaffenheit der Haut, dem verwendeten Rasierhilfsmittel (Seife, Schaum etc.) sowie der Reinigung der Klinge unter Wasser während der Rasur.From US-A-4514904 a razor of this type is known, on the handle of which a razor blade unit is pivotably mounted at the front end by means of an openable and closable fork holder, starting from a spring-loaded zero position about a pivot axis parallel to the cutting edges of the razor blades. The swivel axis defined by the fork holder runs below the cutting edge of the front, lower razor blade of the double razor blade. This creates a torque during shaving that tries to turn the blades clockwise. This type of deflection can lead to an indifferent balance, since the forces that occur during shaving depend on various factors, for example on the individual guidance of the razor, the facial zone in which shaving is carried out, the individual beard thickness, the individual condition of the skin, the shaving aid used (soap, foam, etc.) and cleaning the blade under water while shaving.
Aus der EP-A-0020816 ist ein Rasierapparat bekannt, an dessen vorderem Handgriffende ebenfalls eine Rasierklingeneinheit verschwenkbar gelagert ist. Hier verläuft die Schwenkachse etwa in der Mitte unterhalb der Rasierklingen parallel zu deren Schneidkanten. Auch hier entsteht während der Rasur ein Drehmoment, dessen dadurch bewirkte Auslenkung zu einem indifferenten Gleichgewicht führen kann.From EP-A-0020816 a razor is known, on the front end of which a razor blade unit is also pivotally mounted. Here the swivel axis runs approximately in the middle below the razor blades parallel to their cutting edges. Here, too, a torque is generated during shaving, the deflection of which can lead to an indifferent balance.
Ausgehend von einem Rasierapparat der eingangs angegebenen Art liegt der Erfindung die Aufgabe zugrunde, den bekannten Rasierapparat derart weiterzuentwickeln, daß die Schwenklagerung der Rasierklingeneinheit an der Gabelhalterung des Handgriffes verbessert ist.Starting from a razor of the type specified in the introduction, the object of the invention is to further develop the known razor in such a way that the pivoting position of the razor blade unit on the fork holder of the handle is improved.
Als technische Lösung wird mit der Erfindung vorgeschlagen, daß die Schwenkachse vor der Schneidkante der Rasierklinge verläuft.As a technical solution , the invention proposes that the pivot axis runs in front of the cutting edge of the razor blade.
Ein nach dieser technischen Lehre ausgebildeter Rasierapparat mit einer vor der Schneidkante der Rasierklinge verlaufenden Schwenkachse weist eine optimale Schwenklagerung der Rasierklingeneinheit an der Gabelhalterung des Handgriffs auf, so daß sich während des Rasiervorganges die Rasierklingeneinheit exakt der Gesichtskontur anpaßt. Das während des Rasiervorganges auftretende Drehmoment ist minimal, so daß die aus dem Drehmoment resultierenden Verschwenkbewegungen während des Rasiervorganges relativ gering sind. Dabei erfolgt die Krafteinleitung fast auf der Berührungslinie dar Rasierklinge mit der Haut, so daß somit innerhalb technisch unvermeidbarer Grenzen ein unerwünschte Auslenkungen verursachendes Drehmoment entfällt. Man erhält insgesamt ein stabiles System.A razor designed according to this technical teaching with a pivot axis running in front of the cutting edge of the razor blade has an optimal pivot bearing of the razor blade unit on the fork holder of the handle, so that the razor blade unit adapts exactly to the face contour during the shaving process. The torque occurring during the shaving process is minimal, so that the pivoting movements resulting from the torque during the shaving process are relatively small. The force is applied almost on the line of contact between the razor blade and the skin, so that there is no torque causing unwanted deflections within technically unavoidable limits. Overall, a stable system is obtained.
Bei einem Rasierapparat mit einer Doppelrasierklinge erstreckt sich die Schwenkachse der Gabelhalterung vorzugsweise im Bereich der Schneidkante der unteren, vorderen Rasierklinge.In the case of a razor with a double razor blade, the pivot axis of the fork holder preferably extends in the area of the cutting edge of the lower, front razor blade.
In einer Weiterbildung des erfindungsgemäßen Rasierapparates ist die Schwenkachse unterhalb einer vorderen Führungsleiste angeordnet.In a development of the shaving apparatus according to the invention, the pivot axis is arranged below a front guide bar.
In einer Weiterbildung ist die Rasierklingeneinheit im Bereich der Seitenwände des Kunststoffgehäuses an der Gabelhalterung gelagert. Auf diese Weise ergibt sich eine weit außen liegende Lagerung, was zu einer sicheren Führung führt.In a further development, the razor blade unit is mounted on the fork holder in the area of the side walls of the plastic housing. In this way, there is a storage lying far outside, which leads to a safe guidance.
Die Gabelhalterung ist vorzugsweise als eine im Handgriff gelagerte Feder, insbesondere Drahtfeder, ausgebildet, die einen Betätigungsbereich für die Finger des Benutzers zum Ausrasten der Feder aus der Rasierklingeneinheit aufweist. Dies stellt eine technisch sehr einfach Möglichkeit zum Verrasten des Handgriffes mit der Rasierklingeneinheit dar, wobei insbesondere dadurch eine einfache Einhandbedienung durch den Benutzer ermöglicht wird.The fork holder is preferably designed as a spring mounted in the handle, in particular a wire spring, which has an actuation area for the fingers of the user to disengage the spring from the razor blade unit. This poses represents a technically very simple possibility for locking the handle with the razor blade unit, in particular thereby enabling simple one-hand operation by the user.
In einer bevorzugten Ausführungsform dieser Feder für die Gabelhalterung weist diese ein U-förmiges Grundelement auf, dessen vordere Schenkelenden in der Ebene des Grundfederelements liegende sowie nach außen abstehende Gabelarme aufweisen, die mit ihren vorderen Enden in entsprechenden Aussparungen in der Rasierklingeneinheit eingerastet sind und die Lagerstellen definieren. Das U-förmige Grundfederelement ermöglicht dabei ein einfaches Ausrasten der Gabelhalterung auf der Rasierklingeneinheit, indem die Schenkel dieses Grundfederelements zusammengedrückt werden, so daß die vorderen Enden der Gabelarme nach innen schwenken. Die vorderen Enden der Gabelarme sind dabei vorzugsweise jeweils S-förmig in der Ebene der Feder gebogen und bilden Lagerzapfen. Durch diese Biegung läßt sich die Gabelhalterung des Handgriffes auf einfache Weise ins Innere der Rasierklingeneinheit einführen, so daß auf technisch sehr einfache Weise die Lagerstellen in unmittelbare Nähe zu der vordersten Schneidkante gebracht werden können.In a preferred embodiment of this spring for the fork holder, this has a U-shaped base element, the front leg ends of which have fork arms lying in the plane of the base spring element and projecting outwards, which are engaged with their front ends in corresponding recesses in the razor blade unit and the bearing points define. The U-shaped base spring element enables a simple disengagement of the fork holder on the razor blade unit by pressing the legs of this base spring element together, so that the front ends of the fork arms pivot inwards. The front ends of the fork arms are each preferably S-shaped in the plane of the spring and form trunnions. This bend allows the fork holder of the handle to be inserted into the inside of the razor blade unit in a simple manner, so that the bearing points can be brought into close proximity to the foremost cutting edge in a technically very simple manner.
In einer bevorzugten Weiterbildung weist die Rasierklingeneinheit einen mit der Gabelhalterung korrespondierenden Anschlag für die Nullage auf, gegen den die Nullagenfeder die Rasierklingeneinheit drückt und wobei die Rasierklingeneinheit ausgehend von dieser Nullage nur in eine Richtung, vorzugsweise nach hinten verschwenkbar ist. Als sogenannte Nullagenfeder kann eine U-förmige Feder, eine Blattfeder, eine Schenkelfeder oder dgl. aus Kunststoff oder Metall vorgesehen sein. Vorzugsweise ist die Nullagenfeder am hinteren, oberen Ende des Handgriffs angeordnet und ist an der hinteren Unterseite der Rasierklingeneinheit abgestützt. Auf jeden Fall drückt diese Nullagenfeder die Rasierklingeneinheit in die Nullagenstellung, aus der die Rasierklingeneinheit nur in eine Richtung verschwenkt werden kann. Der Schwenkbereich der Rasierklingeneinheit beträgt dabei vorzugsweise 15° bis 30°. Zusammen mit der nahen Anordnung der Schwenkachse an der Schneidkante der Rasierklinge ergibt dies eine optimale Ausbildung des Rasierapparates hinsichtlich seiner Rasiereigenschaften, da durch die Einseitigkeit der Schwenkbewegung ein gleichbleibender optimaler Anpreßdruck sichergestellt werden kann, der nicht abhängig ist von einer Mittellage.In a preferred development, the razor blade unit has a stop for the zero position corresponding to the fork holder, against which the zero position spring presses the razor blade unit and the razor blade unit can only be pivoted in one direction, preferably backwards, starting from this zero position. A U-shaped spring, a leaf spring, a leg spring or the like made of plastic or metal can be provided as the so-called zero-position spring. The zero-position spring is preferably arranged on the rear, upper end of the handle and is supported on the rear underside of the razor blade unit. In any case, this zero position spring presses the razor blade unit into the zero position position, from which the razor blade unit can only be pivoted in one direction. The swivel range of the razor blade unit is preferably 15 ° to 30 °. Together with the close arrangement of the swivel axis on the Cutting edge of the razor blade results in an optimal design of the razor with regard to its shaving properties, since the one-sided pivoting movement ensures a constant optimal contact pressure, which is not dependent on a central position.

In den Fig. 1 bis 3 sind die verschiedenen Phasen des Zusammenbaus einer Rasierklingeneinheit 1 dargestellt, während Fig. 6 in einer schematischen Schnittdarstellung einen kompletten Rasierapparat 2 zeigt, bei dem die Rasierklingeneinheit 1 aus den Fig. 1 bis 3 am vorderen Ende eines Handgriffes 3 befestigt ist. Dieser Handgriff 3 bzw. Teile davon sind in den Fig. 4 und 5 dargestellt.1 to 3, the various phases of the assembly of a
Die Rasierklingeneinheit 1 besteht aus einem einstückigen Kunststoffgehäuse 4. Dieses weist eine vordere Führungsleiste 5, zwei Seitenwände 6 sowie im Innern eine Klingenplattform 7 auf.The
In dieses Kunststoffgehäuse 4 der Rasierklingeneinheit 1 wird eine Doppelrasierklinge bestehend aus den beiden Rasierklingen 8, 8′ von oben durch eine im Kunststoffgehäuse 4 ausgebildete Öffnung 9 eingesetzt. Zu diesem Zweck sind die beiden Rasierklingen 8, 8′ an einem flachen, länglichen, quaderförmigen Abstandhalter 10 derart unlösbar befestigt, daß der Abstandhalter 10 sandwichartig zwischen den beiden Rasierklingen 8, 8′ festgelegt ist. Die Rasierklingen 8, 8′ sowie der Abstandhalter 10 bilden somit eine sogenannte Rasierklingen/Abstandhalter-Einheit 11. Dabei ist der Abstandhalter 10 etwas länger als die beiden Rasierklingen 8, 8′, so daß der Abstandhalter 10 etwas über die Enden der Rasierklingen 8, 8′ übersteht. Korrespondierend zu diesen Überständen weist die Klingenplattform 7 der Rasierklingeneinheit 1 beidseitig im Bereich der Seitenwände 6 jeweils eine Ausnehmung 12 auf.In this
Wie in Fig. 1 angedeutet ist, wird die Rasierklingen/Abstandhalter-Einheit 11 von oben in Richtung des Pfeiles P in das Kunststoffgehäuse 4 auf die Klingenplattform 7 aufgesetzt. Anschließend wird, wie in Fig. 2 zu erkennen ist, das Kunststoffgehäuse 4 zusammen mit der eingesetzten Rasierklingen/Abstandhalter-Einheit 11 mit Draht 13 umwickelt.As indicated in Fig. 1, the razor blade /
Da bislang die Rasierklingen/Abstandhalter-Einheit 11 nur lose in die Öffnung 9 des Kunststoffgehäuses 4 eingesetzt ist und lediglich durch den Draht 13 gehalten wird, muß eine spezielle Fixierung der Rasierklingen/Abstandhalter-Einheit 11 innerhalb des Kunststoffgehäuses 4 vorgesehen werden. Zu diesem Zweck dient eine Kappe 14 mit einem im wesentlichen U-förmigen Querschnittsprofil. Die über die gesamte Länge des Kunststoffgehäuses 4 sich erstreckende Kappe 14 weist an der Oberseite eine Rasteinrichtung 15 auf. Diese besteht aus endseitigen nach vorne sich erstreckenden Rastarmen 16, die an ihren vorderen Enden jeweils eine Rastnase 17 aufweisen. Korrespondierend zu diesen Rastnasen 17 weist das Kunststoffgehäuse 4 jeweils eine Rastaufnehmung 18 auf.Since so far the razor blades /
Wie in Fig. 2 zu erkennen ist, wird die Kappe 14 in Richtung des Pfeiles P′ von hinten auf das Kunststoffgehäuse 4 derart aufgeschoben, daß die Rastnasen 17 der Kappe 14 in den Rastausnehmungen 18 im Kunststoffgehäuse 4 einrasten. Dieser fertige Montagezustand der Rasierklingeneinheit 1 ist in Fig. 3 dargestellt. Indem die Oberseite der Kappe 14 auf der Rasierklingen/Abstandhalter-Einheit 11 aufliegt, ist diese fest auf der Klingenplattform 7 des Kunststoffgehäuses 4 fixiert.As can be seen in Fig. 2, the
Zur Bildung eines Rasierapparates 2 ist zu der Rasierklingeneinheit 1 ein Handgriff 3 vorgesehen. Dieser weist an seinem vorderen Ende eine spezielle Gabelhalterung 19 auf, mittels der der Handgriff 3 in der Rasierklingeneinheit 1 eingerastet werden kann.To form a
Diese Gabelhalterung 19 besteht aus einer Feder 20 in Form einer Drahtfeder. Diese ist in Fig. 4 für sich alleine ohne den Handgriff 3 dargestellt. Diese Feder 20 besteht zunächst aus einem U-förmigen Grundfederelement 21, dessen vordere Schenkelenden senkrecht nach außen gebogen sind und Gabelarme 22 bilden. Die vorderen Enden der Gabelarme 22 sind dabei S-förmig gebogen und bilden Lagerzapfen 23.This
In Fig. 5 ist gezeigt, wie die Feder 20 der Gabelhalterung 19 im Vorderbereich des Handgriffs 3 angeordnet ist. Die Basis des U-förmigen Grundfederelements 21 ist dabei innerhalb des Handgriffes 3 derart fixiert, daß sich die Schenkel nach vorne hin erstecken. Die Gabelarme 22 kommen dabei in einem T-förmige Fortsatz 24 des Handgriffs 3 zu liegen. Wie in Fig. 5 zu erkennen ist, liegen die Schenkel des Grundfederelements 21 im vorderen Bereich frei. Dadurch werden Betätigungsbereiche B gebildet, so daß durch Zusammendrücken der Schenkel des Grundfederelements 21 die Lagerzapfen 23 der Feder 20 nach innen aufeinander zu verschwenkt werden können. Dies ist durch die Pfeile P˝ angedeutet. Nach Loslassen kehren die Lagerzapfen 23 wieder in ihre Ausgangsstellung zurück.FIG. 5 shows how the
Weiterhin ist in den Fig. 4 und 5 eine sogenannte Nullagenfeder 25 erkennbar. Diese ist in dem dargestellten Ausführungsbeispiel als Blattfeder aus Kunststoff oder Metall ausgebildet und mit ihrem unteren Ende im Handgriff 3 gelagert. Statt der Ausbildung als Blattfeder kann sie auch als U-Feder, als Schenkelfeder etc. ausgebildet sein. Die technische Bedeutung der Nullagenfeder 25 wird später anhand Fig. 6 erläutert.Furthermore, a so-called zero-
Zur Befestigung des Handgriffs 3 an der Rasierklingeneinheit 1 werden zunächst die Lagerzapfen 23 in der beschriebenen Weise nach innen verschwenkt. Dadurch kann die Gabelhalterung 19 in die Rasierklingeneinheit 1 eingeführt werden, wie dies insbesondere in den Fig. 3 und 6 erkennbar ist. Die Rasierklingeneinheit 1 ist dabei im Bereich ihrer Seitenwände 6 jeweils mit einer Aussparung 26 ausgestattet, in die die Lagerzapfen 23 der Gabelhalterung 19 nach Loslassen der Feder 20 einrasten. Wie insbesondere in Fig. 6 erkennbar ist, liegt die durch die Lagerzapfen 23 definierte Schwenkachse S im Bereich der Schneidkante 27 der vorderen Rasierklinge 8, d.h. die Schwenkachse S verläuft vor dieser Schneidkante 27 parallel zu ihr sowie etwas versetzt unterhalb der Ebene dieser vorderen Rasierklinge 8. Wie in Fig. 6 darüber hinaus erkennbar ist, drückt die Nullagenfeder 25 die Rasierklingeneinheit 1 nach vorne gegen einen Anschlag 28 innerhalb des Kunststoffgehäuses 4. Während des Rasiervorganges ist somit die Rasierklingeneinheit 1 nur nach hinten entgegen der Kraft der Nullagenfeder 25 verschwenkbar, wobei der Schwenkbereich zwischen 15° und 30° beträgt.To attach the
