Description

Die Erfindung betrifft einen am vorderen Ende eines Handgriffs angeordneten Rasierapparatekopf, insbesondere Rasierklingeneinheit, eines Naßrasierapparates, bei dem in einem, eine vordere Führungsleiste sowie eine hintere Abdeckkappe aufweisenden Kunststoffkörper eine Einfach- oder Doppelrasierklinge angeordnet ist, wobei die Abdeckkappe mit einem Gleitstreifen versehen ist.The invention relates to a razor head arranged at the front end of a handle, in particular a razor blade unit, of a wet razor, in which a single or double razor blade is arranged in a plastic body having a front guide bar and a rear cover cap, the cover cap being provided with a sliding strip.

Naßrasierapparate sind in verschiedenen Ausführungsformen bekannt. So ist jeweils am vorderen Ende eines Handgriffes ein Rasierapparatekopf angeordnet, der die Einfach- oder Doppelrasierklinge trägt. Dabei kann der vordere Rasierapparatekopf einstückig mit dem Handgriff in Form eines Kunststofformteils ausgebildet sein. Sofern der Rasierappartekopf separat vom Handgriff ausgebildet ist und mittels eines entsprechenden Mechanismus auswechselbar an diesem befestigt werden kann, spricht man von einer sogenannten Rasierklingeneinheit, bei der in einem Kunststoffgehäuse eine Einfach- oder Doppelrasierklinge unlösbar eingebettet ist.Wet shavers are known in various embodiments. A razor head, which carries the single or double razor blade, is arranged at the front end of a handle. The front shaver head can be integrally formed with the handle in the form of a molded plastic part. If the razor head is designed separately from the handle and can be exchangeably attached to it by means of a corresponding mechanism, one speaks of a so-called razor blade unit in which a single or double razor blade is embedded in a plastic housing so that it cannot be detached.

Ein Rasierapparatekopf in Form einer derartigen Rasierklingeneinheit ist in verschiedenen Ausführungsformen bekannt. Grundsätzlich ist dabei ein Kunststoffkörper vorgesehen, in dem eine Einfach- oder Doppelrasierklinge unlösbar eingebettet ist. Im Bereich der Schneidkante(n) der Rasierklinge(n) weist der Kunststoffkörper eine vordere Führungsleiste auf, während im hinteren Bereich eine Abdeckkappe vorgesehen ist. Diese kann mit einem reibungsmindernden Gleitstreifen versehen sein, welcher bei den bekannten Ausführungsformen immer glatt, d.h. eben ausgebildet ist. Mit diesem die Reibung zwischen dem Rasierapparatekopf und der Haut verringernden Gleitstreifen ist zwar eine verbesserte Rasur möglich, doch ist er am Ende des Rasierapparatekopfes nicht besonders wirksam. Darüber hinaus ist es bei diesen bekannten Ausführungsformen immer erforderlich, daß der Winkel relativ stark angestellt sein muß, um den ersten Kontakt des Gleitstreifens zur Haut zuerst an der überliegenden Kante herzustellen. Versuche haben aber gezeigt, daß in bestimmten Bereichen des Gesichts die nachfolgende, hintere Kante des Gleitstreifens nachteiligerweise fühlbar wird, weil das Anschmiegen der Gesichtshaut an die Klinge von dem elastischen Verhalten der Haut abhängig ist. Hier spielen aber individuelle Eigenschaften, wie Alter, Zusammensetzung der Haut, Fettschicht der Haut über Knochenpartien etc. Eine Rolle.A razor head in the form of such a razor blade unit is known in various embodiments. Basically a plastic body is provided in which a single or double razor blade is embedded non-detachably. The plastic body has a front guide strip in the area of the cutting edge (s) of the razor blade (s), while a cover cap is provided in the rear area. This can be provided with a friction-reducing sliding strip, which is always smooth, ie flat, in the known embodiments. With this sliding strip which reduces the friction between the razor head and the skin, an improved shave is possible, but it is not particularly effective at the end of the razor head. In addition, in these known embodiments it is always necessary that the angle must be set relatively strong in order to make the first contact of the sliding strip with the skin first on the overlying edge. Experiments have shown, however, that in certain areas of the face the trailing trailing edge of the slide strip can be felt disadvantageously, because the clinging of the facial skin to the blade depends on the elastic behavior of the skin. Here, however, individual properties such as age, composition of the skin, fat layer of the skin over the bone areas etc. play a role.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Rasierapparatekopf, insbesondere eine Rasierklingeneinheit, eines Naßrasierapparates mit einem verbesserten Gleitstreifen und damit mit einem verbesserten Gleitverhalten zu schaffen.Proceeding from this, the object of the invention is to create a razor head, in particular a razor blade unit, of a wet razor with an improved sliding strip and thus with an improved sliding behavior.

Als technische Lösung wird mit der Erfindung vorgeschlagen, daß der Gleitstreifen konvex gekrümmt ist.As a technical solution , the invention proposes that the sliding strip is convexly curved.

Der so über die Abdeckkappe gebogene Gleitstreifen insbesondere in Form einer beschichteten Folie, der konvex in die Kanten der Abdeckkappe herum ausgebildet ist und dessen Krümmungslinie sich parallel zu der (den) Schneidkante(n) der Rasierklinge(n) erstreckt, kann mittels eines besonderen Heißformverfahrens geschaffen und aufgebracht werden. Der besondere Vorteil liegt dabei darin, daß der Gleitstreifen auch am Ende des Rasierapparatekopfes besser wirksam wird. Da die Haut beim Rasieren gespannt und eingedrückt wird, bildet sich am Ende des Rasierapparatekopfes eine Wulst aus. Der im Radius geformte Gleitstreifen gleitet in diesem Bereich optimal und erhöht somit die sanfte Rasur. Aufgrund der konvexen Ausbildung der den Gleitstreifen bildenden Folie ist selbst bei einem totalen Verlust der Gleitschicht die Form der Abdeckkappe gewährleistet, so daß die Rasiergeometrie auf jeden Fall erhalten bleibt. Schließlich stellt der erfindungsgemäß konvex gekrümmte Gleitstreifen in Form einer konvex gebogenen Folie eine besonders preisgünstige Ausführung eines mit einem Gleitstreifen versehenen Rasierapparatekopfes dar.The sliding strip thus bent over the cover cap, in particular in the form of a coated film, which is convex in the edges of the cover cap and whose line of curvature is the same extending parallel to the cutting edge (s) of the razor blade (s) can be created and applied by means of a special hot molding process. The particular advantage is that the sliding strip is also more effective at the end of the razor head. Since the skin is stretched and pressed in during shaving, a bulge forms at the end of the shaver head. The glide strip shaped in the radius glides optimally in this area and thus increases the gentle shave. Due to the convex design of the film forming the sliding strip, the shape of the covering cap is ensured even in the event of a total loss of the sliding layer, so that the shaving geometry is retained in any case. Finally, the convexly curved sliding strip according to the invention in the form of a convexly curved film represents a particularly inexpensive embodiment of a razor head provided with a sliding strip.

In einer bevorzugten konstruktiven Ausbildung des Gleitstreifens weist dieser einen vorderen, im wesentlichen ebenen oder leicht konvex gekrümmten Gleitstreifenschenkel sowie einen dazu abgewinkelten hinteren, ebenfalls im wesentlichen ebenen oder leicht konvex gekrümmten Gleitstreifenschenkel auf, die durch einen Bogen miteinander verbunden sind. Dies stellt eine optimale Form des Gleitstreifens dar, mit der eine überaus sanfte Rasur möglich ist.In a preferred constructive embodiment of the glide strip, it has a front, essentially flat or slightly convexly curved glide strip leg and an angled rear, also essentially flat or slightly convexly curved glide strip leg, which are connected to one another by an arc. This is an optimal form of the glide strip, with which an extremely gentle shave is possible.

In einer weiteren Weiterbildung wird vorgeschlagen, daß die Abdeckkappe oberseitig eine flache Ausnehmung aufweist, in der der Gleitstreifen aufgenommen ist. Durch die Aufnahme des Gleitstreifens innerhalb der Abdeckkappe steht dieser nicht über letztere über, sondern paßt sich voll an die Oberflächenausbildung der Abdeckkappe an.In a further development it is proposed that the cover cap has a flat recess on the top side in which the sliding strip is received. Due to the inclusion of the sliding strip inside the cover cap, the latter does not protrude above the latter, but adapts fully to the surface formation of the cover cap.

Schließlich wird in einer Weiterbildung vorgeschlagen, daß der Gleitstreifen eine Folie ist, die mit einer gleitfähigen Beschichtung versehen ist. Eine derartige beschichtete Folie hat den Vorteil, daß sie sich sehr leicht in der konvex gekrümmten Form auf die Abdeckkappe aufbringen läßt.Finally, it is proposed in a further development that the sliding strip is a film which is provided with a lubricious coating. Such a coated film has the advantage that it can be very easily applied to the cover cap in the convexly curved shape.

Ein Rasierapparatekopf in Form einer sogenannten Rasierklingeneinheit für einen Naßrasierapparat, die am vorderen Ende eines nicht dargestellten Handgriffes befestigt werden kann, besteht aus einem Kunststoffkörper 1, in dem zwei Rasierklingen 2 angeordnet sind, deren Schneidkanten 3 parallel und versetzt hintereinander verlaufen.A razor head in the form of a so-called razor blade unit for a wet shaver, which can be attached to the front end of a handle, not shown, consists of a plastic body 1 in which two razor blades 2 are arranged, the cutting edges 3 of which run parallel and offset one behind the other.

Der Kunststoffkörper 1 besteht aus einem Basisteil 4 mit den Rasierklingen 2 sowie aus einem auf dieses Basisteil 4 aufgesetztes Oberteil 5.The plastic body 1 consists of a base part 4 with the razor blades 2 and an upper part 5 placed on this base part 4.

Das Basisteil 4 des Kunststoffkörpers 1 weist zunächst im Innern Durchführungsschlitze 6 auf. Oberseitig definiert das Basisteil 4 eine Plattform 7 für die Rasierklingen 2. Zu diesem Zweck ist zwischen den beiden Rasierklingen 2 sandwichartig ein Abstandhalter 8 angeordnet, wobei die beiden Rasierklingen 2 fest mit diesem Abstandhalter 8 verbunden sind. Diese bilden somit eine Rasierklinge/Abstandhalter/Rasierklinge-Einheit 9. Diese wird von oben auf die Plattform 7 des Basisteils 4 aufgesetzt, wobei zu diesem Zweck der Abstandhalter 8 seitlich übersteht und in seitlichen Ausnehmungen 10 des Basisteils 4 aufgenommen ist.The base part 4 of the plastic body 1 initially has feed-through slots 6 on the inside. At the top, the base part 4 defines a platform 7 for the razor blades 2. For this purpose, a spacer 8 is sandwiched between the two razor blades 2, the two razor blades 2 being firmly connected to this spacer 8. These thus form a razor blade / spacer / razor blade unit 9. This is placed on the platform 7 of the base part 4 from above, the spacer 8 projecting laterally for this purpose and being received in lateral recesses 10 of the base part 4.

Gehalten wird die Einheit 9 mittels eines zickzackförmig verlaufenden Drahtes 11, der über die Oberseite 12 der Einheit 9 und somit des Basisteils 4 des Kunststoffkörpers 1 geführt ist. Zur Führung des Drahtes 11 weist das Basisteil 4 an der Vorderseite 13 im unteren Bereich nach unten gerichtete, angeformte Vorsprünge 14 auf, die als längliche Leisten ausgebildet sind. Die Breite dieser Vorsprünge 14 in Richtung der Schneidkanten 3 der Rasierklingen 2 gesehen entspricht dabei im wesentlichen dem Abstand zwischen den Vorsprüngen 14. Im vorderen Bereich weisen dabei die Vorsprünge 14 einen hochgezogenen Ansatz 15 auf.The unit 9 is held by means of a zigzag wire 11 which extends over the top 12 of the unit 9 and thus the base part 4 of the plastic body 1 is guided. For guiding the wire 11, the base part 4 has, on the front 13 in the lower region, downward-shaped molded projections 14 which are designed as elongated strips. The width of these projections 14 in the direction of the cutting edges 3 of the razor blades 2 essentially corresponds to the distance between the projections 14. In the front region, the projections 14 have a raised extension 15.

Entsprechend weist die Rückseite 16 des Basisteils 4 Vorsprünge 14' auf, welche nach hinten gerichtet sind. Diese Vorsprünge 14' füllen dabei die Lücken zwischen den Vorsprüngen 14 der Vorderseite 13 aus. Entsprechend den Vorsprüngen 14 weisen auch die Vorsprünge 14' Ansätze 15' auf, die jedoch nach unten gerichtet sind. Schließlich sind an der Rückseite 16 des Basisteils 4 endseitig jeweils Befestigungsvorsprünge 17 angeformt.Correspondingly, the rear side 16 of the base part 4 has projections 14 ′ which are directed towards the rear. These projections 14 ′ fill the gaps between the projections 14 on the front 13. Corresponding to the projections 14, the projections 14 'also have projections 15' which, however, are directed downwards. Finally, fastening projections 17 are integrally formed on the rear side 16 of the base part 4.

Der Draht 11 ist zunächst mit seinem einen Ende am einen Befestigungsvorsprung 17 befestigt. Anschließend ist er über die Einheit 9 nach vorne zum Vorsprung 14 geführt und um diesen herumgeführt, um anschließend um 180° wieder nach hinten über die Einheit 9 zu verlaufen, wo der Draht 11 um den dortigen Vorsprung 14' herum geführt ist. Der Draht 11 wird so nacheinander um die Vorsprünge 14 und 14' geführt, um schließlich mit seinem anderen Ende am Befestigungsvorsprung 17 auf der anderen Seite des Basisteils 4 befestigt zu werden. Die Abschnitte des Drahtes 11 verlaufen dabei im Bereich der Oberseite 12 parallel zueinander und mit im wesentlichen konstanten Abständen. Der Draht 11 hält einerseits die Einheit 9 fest auf der Plattform 7 des Basisteils 4 und verhindert zum anderen Hautverletzungen.The wire 11 is first fastened with its one end to a fastening projection 17. Then it is guided via the unit 9 to the front to the projection 14 and around it, in order to subsequently run back through 180 ° over the unit 9, where the wire 11 is guided around the projection 14 ′ there. The wire 11 is thus guided in succession around the projections 14 and 14 ′ in order to finally be attached at its other end to the attachment projection 17 on the other side of the base part 4. The sections of the wire 11 run parallel to one another in the region of the upper side 12 and at substantially constant intervals. The wire 11 on the one hand holds the unit 9 firmly on the platform 7 of the base part 4 and on the other hand prevents skin injuries.

Das Oberteil 5 ist ein einstückiges Kunststoffbauteil und weist zunächst eine vordere Führungsleiste 18 auf. Diese erstreckt sich parallel zu den Schneidkanten 3 der Rasierklingen 2 und weist eine treppenartige Längsprofilierung 19 auf. Im hinteren Bereich ist eine Abdeckkappe 20 vorgesehen. Diese weist oberseitig einen Gleitstreifen 21 auf. Dieser ist konvex gekrümmt und weist zunächst einen ersten Gleitstreifenschenkel 22 sowie einen dazu spitz abgewinkelten zweiten Gleitstreifenschenkel 22' auf, die durch einen Bogen 23 miteinander verbunden sind. Der Winkel zwischen den Gleitstreifenschenkeln 22,22' kann auch rechtwinklig oder stumpf sein. Die beiden Gleitstreifenschenkel 22,22' sind dabei im wesentlichen eben oder leicht konvex gekrümmt ausgebildet. Die Herstellung eines derartigen Gleitstreifens 21 ist mittels eines besonderen Heißformverfahrens möglich. Der besondere Vorteil dieses Gleitstreifens 21 liegt darin, daß er auch am Ende der Rasierklingeneinheit besser wirksam wird. Da die Haut beim Rasieren gespannt und eingedrückt wird, bildet sich am Ende der Rasierklingeneinheit eine Wulst aus. Der im Radius geformte Gleitstreifen 21 gleitet dabei in diesem Bereich besser und erhöht somit die sanfte Rasur.The upper part 5 is a one-piece plastic component and initially has a front guide bar 18. This extends parallel to the cutting edges 3 of the razor blades 2 and has a step-like longitudinal profile 19. A cover cap 20 is provided in the rear area. This has a sliding strip 21 on the upper side. This is convexly curved and initially has a first glide strip leg 22 and a second glide strip leg 22 ′, which is angled to an acute angle, and which are connected to one another by an arc 23. The angle between the sliding strip legs 22, 22 'can also be rectangular or obtuse. The two sliding strip legs 22, 22 'are essentially flat or slightly convex. The production of such a sliding strip 21 is possible by means of a special hot molding process. The particular advantage of this sliding strip 21 is that it is also more effective at the end of the razor blade unit. Since the skin is stretched and pressed in during shaving, a bulge forms at the end of the razor blade unit. The sliding strip 21 shaped in the radius slides better in this area and thus increases the gentle shave.

Die vordere Führungsleiste 18 und die hintere Abdeckkappe 20 sind durch Seitenwände 24 miteinander verbunden. Zwischen diesen Teilen befindet sich eine Öffnung 25 im Bereich der Schneidkanten 3 der Rasierklingen 2, wie insbesondere die Draufsicht gemäß Fig. 1 erkennen läßt.The front guide strip 18 and the rear cover cap 20 are connected to one another by side walls 24. Between these parts there is an opening 25 in the area of the cutting edges 3 of the razor blades 2, as can be seen in particular from the top view according to FIG. 1.

Sowohl die Innenseite der Führungsleiste 18 als auch die Innenseite der Abdeckkappe 20 weist Aufnahmerillen 26 für den Draht 11 auf. Unterhalb der Führungsleiste 18 sind Ausnehmungen 27 vorgesehen, die mit den Vorsprüngen 14 des Basisteils 4 korrespondierend ineinandergreifen. Rückseitig weist das aus der Führungsleiste 18, der Abdeckkappe 20 und den Seitenwänden 24 gebildete Oberteil 5 Durchführungsöffnungen 28 auf, welche mit entsprechenden Durchführungsöffnungen im Abstandhalter 8 korrespondieren.Both the inside of the guide bar 18 and the inside of the cover cap 20 have receiving grooves 26 for the wire 11. Underneath the guide bar 18 there are recesses 27 which engage in a corresponding manner with the projections 14 of the base part 4. On the back this shows from the guide bar 18, the cover cap 20 and the side walls 24 formed upper part 5 through openings 28 which correspond to corresponding through openings in the spacer 8.

Im fertig montierten Zustand wird das Oberteil 5 auf das Basisteil 4 mit der durch den Draht 11 befestigten Einheit 9 von oben aufgesteckt und beispielsweise durch Verrastung oder auf andere Art und Weise gesichert. Dort wo das Oberteil 5 innenseitige Aufnahmerillen 26 aufweist, verläuft darin der Draht 11.In the fully assembled state, the upper part 5 is plugged onto the base part 4 with the unit 9 fastened by the wire 11 and secured from above, for example by latching or in another way. Where the upper part 5 has receiving grooves 26 on the inside, the wire 11 runs therein.

Der Verlauf des Drahtes 11 im Bereich der Oberseite 12 bringt den Vorteil mit sich, daß die Unterseite 29 des Kunststoffkörpers 1 frei bleibt und damit entsprechende Befestigungssysteme vorgesehen werden können.The course of the wire 11 in the area of the top 12 has the advantage that the bottom 29 of the plastic body 1 remains free and corresponding fastening systems can thus be provided.
