Abstract

A wet razor having a handle, on the front end of which is disposed a razor head that carries a razor blade, is provided. In the region between the razor head and a grasping portion of the handle, there is provided a turning mechanism via which the razor head, with its razor blade, is freely rotatable relative to the grasping portion of the handle about an axis of rotation that is perpendicular to the cutting edge of the razor blade. Associated with the turning mechanism 5 is a spring-type resetting mechanism via which the razor head, starting from a prescribed starting position and after a limited deflection or travel, can automatically return to the starting position due to spring force.

Description

Die Erfindung betrifft einen Haßrasierapparat mit einem Hand­griff, an dessen vorderem Ende ein eine Rasierklinge tragender Rasierapparatekopf angeordnet ist, wobei im Bereich zwischen dem Rasierapparatekopf und dem Griffbereich des Handgriffs eine Dreheinrichtung vorgesehen ist, mittels der der Rasierapparate­kopf mit seiner Rasierklinge bezüglich zum Griffbereich des Handgriffs um eine zur Schneidkante der Rasierklinge senkrechte Drehachse frei drehbar ist.The invention relates to a hat razor with a handle, at the front end of which a razor head carrying a razor blade is arranged, a rotating device being provided in the region between the razor head and the handle area of the handle, by means of which the razor head with its razor blade is turned relative to the handle area of the handle an axis of rotation perpendicular to the cutting edge of the razor blade is freely rotatable.

Ein Naßrasierapparat dieser Art ist aus der GB-PS 610 997 bekannt. Er weist einen Handgriff auf, an dessen vorderem Ende ein Rasierapparatekopf drehbar angeordnet ist, welcher die Rasierklinge trägt. Zu diesem Zweck ist innerhalb des Handgriffs eine Achse drehbar gelagert, an deren vorderem Ende der Rasier­apparatekopf mit der Rasierklinge fest angeordnet ist. Um während der Rasur bei Bedarf die Drehbewegung des Rasier­apparatekopfes ausschalten zu können, besteht der Handgriff aus drei sektorartigen Griffteilen, welche durch entsprechend festes Umgreifen des Handgriffes derart nach innen bewegt werden können, daß sich die Achse innerhalb des Handgriffes nicht mehr drehen kann.A wet shaver of this type is known from GB-PS 610 997. It has a handle, at the front end of which a razor head is rotatably arranged, which carries the razor blade. For this purpose, an axis is rotatably mounted within the handle, at the front end of which the razor head with the razor blade is fixed. In order to be able to switch off the rotary motion of the razor head during shaving, the handle consists of three sector-like handle parts, which can be moved inwards by appropriately gripping the handle in such a way that the axis can no longer rotate within the handle.

Der bekannte Haßrasierapparat mit dem frei drehbaren Rasier­apparatekopf hat zunächst den Nachteil, daß die bei der Rasur auftretenden Widerstandskräfte zu einem sehr schnellen Auslenken und damit Verstellen des Rasierapparatekopfes führen. Dies führt nicht zu einem optimalen Rasierergebnis. Darüber hinaus bleibt der Rasierapparatekopf nach Abheben von der Gesichtsfläche in der jeweiligen Drehposition, so daß für den nachfolgenden Rasiervorgang der Rasierapparatekopf zunächst in seine Ausgangslage zurückkehren muß. Dies geschieht dadurch, daß der Rasierapparatekopf beim Aufdrücken auf die Gesichtsfläche zurückverschwenkt wird, was ebenfalls den Rasierkomfort beeinträchtigt. Alternativ kann der Benutzer den Handgriff in die neue Position drehen, was ebenfalls umständlich ist. Schließlich ist bei dem bekannten Naßrasierapparat mit dem endlos drehenden Rasierapparatekopf von Nachteil, daß beim Rasieren insbesondere in längeren Zügen über die Kinnpartie hinaus der Rasierapparatekopf mit der Rasierklinge derart verdreht wird, daß sich ein derart gefährlicher Winkel zur Bewegungsrichtung einstellt, daß eine Bewegungskomponente in Richtung der Schneidkante der Rasierklinge entsteht. Diese Bewegungskomponente kann zu Schnittverletzungen führen, wenn der Winkel einen kritischen Wert überschreitet.The known hat razor with the freely rotatable razor head initially has the disadvantage that the resistance forces occurring during shaving lead to very rapid deflection and thus adjustment of the razor head. This does not lead to an optimal shaving result. In addition, the razor head remains in the respective rotational position after lifting off the face, so that for the subsequent shaving process Shaver head must first return to its original position. This is done in that the razor head is pivoted back when pressed onto the face, which also affects the comfort of shaving. Alternatively, the user can turn the handle into the new position, which is also cumbersome. Finally, it is disadvantageous in the known wet shaver with the endlessly rotating shaver head that when shaving, especially in longer strokes beyond the chin area, the shaver head is rotated with the razor blade in such a way that such a dangerous angle to the direction of movement is established that a movement component in the direction of the The cutting edge of the razor blade is created. This movement component can lead to cuts if the angle exceeds a critical value.

Davon ausgehend liegt der Erfindung die Aufgabe zu­grunde, den bekannten Naßrasierapparat derart weiterzuent­wicklen, daß die Dreheinrichtung unter Vermeidung der Nachteile des bekannten Rasierapparates verbessert ist.Proceeding from this, the object of the invention is to further develop the known wet shaving apparatus in such a way that the rotating device is improved while avoiding the disadvantages of the known shaving apparatus.

Als technische Lösung wird eine der Dreheinrichtung zuge­ordnete Federrückstelleinrichtung vorgeschlagen, mittels der der Rasierapparatekopf ausgehend von einer vorgegebenen Ausgangslage nach begrenzter Auslenkung aufgrund der Federkraft wieder selbsttätig in die Ausgangslage zurückstellbar ist.As a technical solution , a spring return device assigned to the rotating device is proposed, by means of which the shaving head can be automatically returned to the starting position, starting from a predetermined starting position after limited deflection due to the spring force.

Die der Dreheinrichtung zugeordnete Federrückstelleinrichtung hat den Vorteil, daß die bei der Rasur auftretenden Widerstands­kräfte nicht so schnell zu einem Auslenken und Verstellen des Rasierapparatekopfes und damit der Rasierklinge führen. Dies führt insgesamt zu einer sehr sanften und gründlichen Rasur. Durch eine entsprechende Ausbildung der Feder läßt sich ein wohldefiniertes Rückstellverhalten schaffen, wobei die Grenze für das Drehmoment vorzugsweise zwischen 10 Nmm und 100 Nmm liegt.The spring return device assigned to the rotating device has the advantage that the resistance forces occurring during shaving do not lead to deflection and adjustment of the razor head and thus the razor blade so quickly. Overall, this leads to a very gentle and thorough shave. Appropriate design of the spring allows a well-defined resetting behavior to be created, the limit for the torque preferably being between 10 Nmm and 100 Nmm.

Die Federrückstellung hat darüber hinaus den Vorteil, daß der Rasierapparatekopf mit der Rasierklinge nach Abheben von der Gesichtsfläche in die vorgegebene Ausgangslage zurückkehrt.The spring return also has the advantage that the razor head with the razor blade returns to the predetermined starting position after lifting off the face.

In einer bevorzugten Weiterbildung wird vorgeschlagen, daß die Auslenkung durch Anschläge begrenzt ist. Vorzugsweise ist dabei die Auslenkung ausgehend von der Ausgangslage in beiden Dreh­richtungen auf maximal ungefähr 30° begrenzt. Dies bringt den Vorteil mit sich, daß keine kritische Bewegungskomponente in Richtung der Rasierklingenschneide entsteht, welche zu Schnitt­verletzungen führen könnte. Dieser kritische Winkel liegt bei ungefähr plus/minus 30°, so daß aus den oben genannten Gründen tunlichst eine Bewegung über diesen Winkel hinaus durch den erfindungsgemäßen Anschlag verhindert werden sollte. Selbstverständlich kann der Winkel auch kleiner als 30° sein.In a preferred development, it is proposed that the deflection is limited by stops. The deflection is preferably limited to a maximum of approximately 30 ° in both directions of rotation, starting from the starting position. This has the advantage that there is no critical movement component in the direction of the razor blade edge, which could lead to cut injuries. This critical angle is approximately plus / minus 30 °, so that for the reasons mentioned above, a movement beyond this angle should be prevented by the stop according to the invention. Of course, the angle can also be less than 30 °.

In einer bevorzugten konstruktiven Ausbildung ist der Griff­bereich des Handgriffs durch eine Hülse gebildet, welche auf dem eigentlichen Handgriff drehbar gelagert ist und zwischen der und dem eigentlichen Handgriff die Feder abgestützt ist. Während der Rasur wird somit der Benutzer die Hülse umgreifen, innerhalb der sich dann der eigentliche Handgriff entgegen der Federkraft frei drehen und sich so optimal der Gesichtskontur anpassen kann.In a preferred constructive embodiment, the grip area of the handle is formed by a sleeve which is rotatably mounted on the actual handle and the spring is supported between the and the actual handle. During the shave, the user will therefore grip the sleeve, within which the actual handle can then rotate freely against the spring force and thus optimally adapt to the contour of the face.

Vorzugsweise ist die Feder eine Wendelfeder, die im Bereich der den Griffbereich bildenden Hülse den im Innern befindlichen, eigentlichen Handgriff umgibt. Dies stellt eine technisch einfache Möglichkeit zur Ausbildung der Federrückstellein­richtung dar, wobei durch die entsprechende Ausbildung der Wendelfeder ein wohldefiniertes Federverhalten erzeugt werden kann.The spring is preferably a helical spring which, in the region of the sleeve forming the grip region, surrounds the actual handle located on the inside. This represents a technically simple possibility for the formation of the spring return device, whereby a well-defined spring behavior can be generated by the corresponding formation of the helical spring.

Eine weitere Weiterbildung schlägt vor, daß die Hülse im wesent­lichen im mittleren Bereich des Handgriffs angeordnet ist. Dies bedeutet, daß der eigentliche, drehbare Handgriff immer noch zugänglich ist, insbesondere am unteren Ende des Handgriffs. Dies bringt den Vorteil mit sich, daß durch ein entsprechendes Umgreifen sowohl der Hülse als auch dieses Abschnittes des eigentlichen, drehbaren Handgriffes eine Arretierung durch den Benutzer möglich ist, mittels der dieser bei Bedarf die Drehbe­wegung auf einfache Weise verhindern kann.A further development suggests that the sleeve is arranged essentially in the central region of the handle. This means that the actual, rotatable handle is still is accessible, especially at the lower end of the handle. This has the advantage that by appropriately reaching around both the sleeve and this section of the actual, rotatable handle, a locking by the user is possible, by means of which the user can easily prevent the rotary movement if necessary.

In einer bevorzugten Ausgestaltung der Dreheinrichtung ist diese im vorderen Bereich des Handgriffs ausgebildet. Dies läßt sich technisch auf überaus einfache Weise realisieren, wobei der vordere Teil des Handgriffs zusammen mit dem Rasierapparatekopf und seiner Rasierklinge bezüglich zum hinteren, den Griffbereich aufweisenden Teil des Handgriffs drehbar ist. Auf diese Weise ist eine stabile Verbindung zwischen dem Handgriff und dem Rasierapparatekopf geschaffen, wobei es aber grundsätzlich auch denkbar ist, die Dreheinrichtung zwischen dem vorderen Ende des Handgriffs und dem Rasierapparatekopf anzuordnen.In a preferred embodiment of the rotating device, it is formed in the front region of the handle. This can be achieved technically in a very simple manner, the front part of the handle being rotatable together with the razor head and its razor blade with respect to the rear part of the handle having the handle area. In this way, a stable connection is created between the handle and the razor head, but it is also fundamentally conceivable to arrange the rotating device between the front end of the handle and the razor head.

Um eine gute Führung zwischen den Drehteilen und damit eine optimale Stabilität zu schaffen, wird in einer Weiterbildung vorgeschlagen, daß im Bereich der Dreheinrichtung die Drehteile mit ihren Flächen eben aneinanderliegen.In order to provide good guidance between the rotating parts and thus optimum stability, it is proposed in a further development that the surfaces of the rotating parts lie flat against one another in the region of the rotating device.

In einer ersten Ausführungform liegt die Drehachse der Drehein­richtung in der Längsmittelachse des Handgriffs. In einer alter­nativen zweiten, bevorzugten Ausführungsform erstreckt sich dem­gegenüber die Drehachse der Dreheinrichtung senkrecht zur Ebene der Rasierklinge. Dadurch lassen sich optimale Rasierergebnisse erzielen.In a first embodiment, the axis of rotation of the rotating device lies in the longitudinal central axis of the handle. In an alternative second, preferred embodiment, on the other hand, the axis of rotation of the rotating device extends perpendicular to the plane of the razor blade. This enables optimal shaving results to be achieved.

In einer Weiterbildung kann für die Rasierklinge eine vom Rasierapparatekopf separate und an sich bekannte Rasierklingen­einheit vorgesehen sein, die schwenkbar am Rasierapparatekopf angeordnet ist. Die Rasierklingeneinheit kann dabei sowohl um eine zur Schneidkante parallele Aschse als auch zusätzlich noch um eine dazu senkrechte Achse schwingbar am Rasierapparatekopf angeordnet sein, so daß zusammen mit der drehbaren Anordnung des Rasierapparatekopfes am Handgriff gewissermaßen eine kardanische Aufhängung der Rasierklinge mit Schwingmöglichkeiten um maximal drei Achsen geschaffen ist.In a further development, a razor blade unit, which is separate from the razor head and is known per se, can be provided for the razor blade and is pivotably arranged on the razor head. The razor blade unit can be both around an axis parallel to the cutting edge and additionally about a perpendicular axis to be arranged on the razor head so that, together with the rotatable arrangement of the razor head on the handle, a gimbal suspension of the razor blade with oscillation possibilities about a maximum of three axes is created.

Further details and advantages result from the following description of the associated drawing, in which two exemplary embodiments of a wet shaving apparatus according to the invention are shown. The drawing shows:
  • Figure 1 is a schematic side view of a first embodiment of a wet shaver.
  • Figure 2 shows a second embodiment of a wet shaver, also in a schematic side view.
  • 3 shows a detail of the first embodiment in FIG. 1 in the area of the rotating device, partly in section;
  • Fig. 4 is a schematic section through the rotating device in Fig. 3 in the area of the stop.

Beide in den Figuren 1 und 2 dargestellte Ausführungsformen eines Naßrasierapparates weisen jeweils einen Handgriff 1 auf, an dessen vorderem Ende ein Rasierapparatekopf 2 angeordnet, beispielsweise aufsteckbar ist. Im Rasierapparatekopf 2 ist eine Rasierklinge 3 fest angeordnet. Die Ebene der Rasierklinge 3 schließt dabei mit der Längsmittelachse L des Handgriffs 1 einen spitzen Winkel ein.Both embodiments of a wet shaver shown in FIGS. 1 and 2 each have a handle 1, at the front end of which a shaver head 2 is arranged, for example can be plugged on. A razor blade 3 is fixedly arranged in the razor head 2. The plane of the razor blade 3 includes an acute angle with the longitudinal central axis L of the handle 1.

Bei der ersten Ausführungsform gemäß Fig. 1 sowie mit den zuge­hörigen Fig. 3 und 4 besteht der Handgriff 1 aus einem hinteren Teil 1′ sowie aus einem vorderen Teil 1˝. Fig. 3 läßt dabei er­kennen, daß das vordere Teil 1˝ an seinem unteren Ende eine Verbindungsstange 1‴ aufweist, auf die der hintere Teil 1′ des Handgriffs 1 fest aufgeschraubt ist, so daß der hintere Teil 1′ über die Verbindungsstange 1‴ mit dem vorderen Teil 1˝ fest verbunden ist. Im Bereich dieser Verbindungsstange 1‴ des Handgriffs 1 ist eine Hülse 4 um die Längsmittelachse L des Handgriffs 1 drehbar gelagert. Diese Hülse 4 bildet den Griff­bereich für den Benutzer und definiert eine Dreheinrichtung 5, mittels der, wenn der Benutzer die den Griffbereich definierende Hülse 4 fest umgreift, der hintere Teil 1′, die Verbindungs­stange 1‴, der vordere Teil 1˝ des Handgriffs 1 zusammen mit dem Rasierapparatekopf 2 und der Rasierklinge 3 um eine zur Schneidkante 5 der Rasierklinge 3 senkrechte Drehachse D frei drehbar ist, wobei bei dieser Ausführungsform die Drehachse D der Dreheinrichtung 5 in der Längsmittelachse L des Handgriffs 1 liegt. Entsprechend ist die Rotationsebene senkrecht zur Längs­mittelachse L des Handgriffs 1.In the first embodiment according to FIG. 1 and with the associated FIGS. 3 and 4, the handle 1 consists of a rear part 1 'and a front part 1˝. Fig. 3 shows that the front part 1˝ at its lower end Connecting rod 1 ‴, on which the rear part 1 'of the handle 1 is screwed tightly, so that the rear part 1' is firmly connected via the connecting rod 1 ‴ to the front part 1˝. In the area of this connecting rod 1 ‴ of the handle 1, a sleeve 4 is rotatably mounted about the longitudinal central axis L of the handle 1. This sleeve 4 forms the grip area for the user and defines a rotating device 5, by means of which, when the user firmly grips the sleeve 4 defining the grip area, the rear part 1 ', the connecting rod 1 ‴, the front part 1˝ of the handle 1 together with the razor head 2 and the razor blade 3 is freely rotatable about an axis of rotation D perpendicular to the cutting edge 5 of the razor blade 3, in this embodiment the axis of rotation D of the rotating device 5 lies in the longitudinal center axis L of the handle 1. Accordingly, the plane of rotation is perpendicular to the longitudinal central axis L of the handle 1.

Der Dreheinrichtung 5 ist eine Federrückstelleinrichtung 6 zu­geordnet, welche eine Ausgangslage des Rasierapparates definiert. Diese Federrückstelleinrichtung 6 weist eine Feder 7 in Form einer Wendelfeder auf, welche die Verbindungsstange 1‴ des Handgriffs 1 umgibt sowie mit dem einen Ende im vorderen Teil 1˝ des Handgriffs 1 und dem anderen Ende in der Hülse 4 festgelegt ist.A spring return device 6 is assigned to the rotating device 5 and defines a starting position of the shaving apparatus. This spring return device 6 has a spring 7 in the form of a helical spring, which surrounds the connecting rod 1 ‴ of the handle 1 and is fixed with one end in the front part 1˝ of the handle 1 and the other end in the sleeve 4.

Weiterhin ist zwischen dem vorderen Teil 1˝ und der Hülse 4 ein Anschlag 8 vorgesehen, der in Fig. 4 erkennbar ist und der die Drehbewegung des Rasierapparatekopfes 2 bezüglich zur Hülse 4 ausgehend von der Ausgangslage beidseitig auf 30° begrenzt. Zu diesem Zweck ist die Hülse 4 mit einem radial nach innen gerichteten Vorsprung 9 und der vordere Teil 1˝ des Handgriffs 1 mit einer teilringförmigen Ausnehmung 10 versehen.Furthermore, a stop 8 is provided between the front part 1˝ and the sleeve 4, which can be seen in FIG. 4 and which limits the rotary movement of the razor head 2 with respect to the sleeve 4 on both sides to 30 ° from the starting position. For this purpose, the sleeve 4 is provided with a radially inward projection 9 and the front part 1˝ of the handle 1 with a partially annular recess 10.

Bei der alternativen Ausführungsform in Fig. 2 besteht der Hand­griff 1 aus dem hinteren Griffbereich 11 sowie aus dem Handgriffvorderteil 12, an dem der Rasierapparatekopf 2 angeordnet ist. Zwischen diesem Griffbereich 11 und dem Hand­griffvorderteil 12 des Handgriffs 1 ist wiederum eine Drehein­richtung 5 vorgesehen. Dabei ist die Drehachse D bezüglich zur Längsmittelachse L des Handgriffs 1 geneigt und erstreckt sich dabei im wesentlichen senkrecht zur Ebene der im Rasierapparate­kopf 2 angeordneten Rasierklinge 3. Entsprechend ist das vordere Ende des Griffbereiches 11 im Bereich der Dreheinrichtung 5 des Handgriffs 1 abgeschrägt.In the alternative embodiment in Fig. 2, the handle 1 consists of the rear grip area 11 and the Handle front part 12 on which the shaver head 2 is arranged. A turn device 5 is again provided between this handle area 11 and the handle front part 12 of the handle 1. The axis of rotation D is inclined with respect to the longitudinal center axis L of the handle 1 and extends essentially perpendicular to the plane of the razor blade 3 arranged in the razor head 2. Accordingly, the front end of the handle area 11 is chamfered in the area of the rotating device 5 of the handle 1.

Die Dreheinrichtung 5 dieser zweiten Ausführungsform kann auf geeignete Weise ausgebildet sein, indem beispielsweise das Handgriffvorderteil 12 über einen Drehzapfen im Griffbereich 11 drehbar gelagert ist. Weiterhin ist eine geeignete Federrück­stelleinrichtung vorzusehen.The rotating device 5 of this second embodiment can be designed in a suitable manner, for example by the handle front part 12 being rotatably mounted in the handle area 11 via a pivot pin. A suitable spring return device must also be provided.

Durch die Ausbildung der Dreheinrichtung 5 im Handgriff 1 folgt bei beiden Ausführungsformen der Rasierapparatekopf 2 und damit die Rasierklinge 3 optimal der Gesichtskontur während des Rasiervorganges. Durch die Dreheinrichtung 5 richtet sich der Rasierapparatekopf 2 immer richtig aus, ohne daß beispielsweise die Gefahr des Verkantens besteht. Die Federrückstelleinrichtung 6 verhindert dabei ein zu schnelles Auslenken und Verstellen des Rasierapparatekopfes 2 durch die bei der Rasur auftretenden Widerstandskräfte. Darüber hinaus wird durch die Federrückstell­einrichtung 6 gewährleistet, daß der Rasierapparatekopf 2 nach Abheben von der Gesichtsfläche in die definierte Ausgangslage zurückkehrt. Der Anschlag 8, der sowohl bei der ersten Aus­führungsform als auch bei der zweiten Ausführungsform vorgesehen ist und der den Schwenkwinkel des Rasierapparatekopfes 2 auf ca. plus/minus 30° beschränkt, verhindert eine Bewegungskomponente in Richtung der Schneidkante S der Rasierklinge 3, die zu Schnittverletzungen führt.The design of the rotating device 5 in the handle 1 optimally follows the razor head 2 and thus the razor blade 3 of the face contour during the shaving process in both embodiments. By means of the rotating device 5, the razor head 2 is always correctly aligned without, for example, the risk of tilting. The spring return device 6 prevents the razor head 2 from being deflected and adjusted too quickly by the resistance forces that occur during shaving. In addition, the spring return device 6 ensures that the razor head 2 returns to the defined starting position after lifting off the face. The stop 8, which is provided both in the first embodiment and in the second embodiment and which limits the pivoting angle of the razor head 2 to approximately plus / minus 30 °, prevents a movement component in the direction of the cutting edge S of the razor blade 3, which leads to cuts leads.

Bei den dargestellten Ausführungsbeispielen ist die Rasierklinge 3 fest im Rasierapparatekopf 2 angeordnet. Statt dessen ist es aber auch denkbar, eine sogenannte Rasierklingeneinheit vorzusehen, bei der die Rasierklinge unlösbar in einem Kunststoffgehäuse eingebettet ist, welches seinerseits am Rasierapparatekopf beispielsweise mittels einer Gabelhalterung gehalten ist. Auf diese Weise ist es zusätzlich möglich, daß die Rasierklingeneinheit um eine zur Schneidkante der Rasierklinge parallele Achse schwingbar am Rasierapparatekopf gelagert ist. Darüber hinaus ist es auch noch denkbar, die Rasier­klingeneinheit um eine dazu senkrechte Achse schwingen zu lassen, so daß dann gewissermaßen eine kardanische Lagerung der Rasierklinge 3 mit optimalen Einstellmöglichkeiten geschaffen ist.In the illustrated embodiments, the razor blade 3 is fixed in the razor head 2. Instead, however, it is also conceivable to provide a so-called razor blade unit, in which the razor blade is embedded in a non-detachable manner in a plastic housing, which in turn is held on the razor head, for example by means of a fork holder. In this way, it is additionally possible for the razor blade unit to be mounted on the razor head so as to be oscillatable about an axis parallel to the cutting edge of the razor blade. In addition, it is also conceivable to allow the razor blade unit to swing about an axis perpendicular thereto, so that a gimbal bearing of the razor blade 3 with optimal adjustment options is then created.
