Es ist eine Aufgabe der Erfindung, einen verbesserten Rasierer bereitzustellen. It is an object of the invention to provide an improved razor.
In einem Aspekt bezieht sich die Erfindung auf einen Rasierer mit einem Griff, an dessen ei- nen Ende eine Kugelgelenkpfanne angeordnet ist, und einem Klingenkopf mit mindestens einer Rasierklinge und einem Kugelgelenkkopf, wobei der Kugelgelenkkopf des Klingenkopfes und die Kugelgelenkpfanne des Griffs ein Kugelgelenk bilden und wobei der Griff ein Ausrichtungselement in der Kugelgelenkpfanne aufweist, welches ausgestaltet ist, um in eine Ausnehmung in dem Kugelgelenkkopf einzugreifen. In one aspect, the invention relates to a razor having a handle having a ball joint socket disposed at one end thereof and a blade head having at least one razor blade and a ball joint head, the ball joint head of the blade head and the ball joint socket of the handle forming a ball joint and wherein the handle includes an alignment member in the ball joint socket configured to engage a recess in the ball joint head.
Der Erfindung liegt die Idee zugrunde, dass ein Rasierer angenehmer und für die Rasur zuverlässig zu verwenden ist, dessen Klingenkopf mittels einer Anordnung in einem Kugelgelenk frei rotierbar ist. So kann der Klingenkopf bzw. dessen Rasierklinge(n) sich besonders gut Hautunebenheiten anpassen. Der Klingenkopf passt sich vorteilhaft flexibel eventuellen Hautunebenheiten oder -krümmungen an und ermöglicht so eine besonders gründliche und sichere Rasur. Der Klingenkopf gleitet sanft und mit sich selbst den Hautunebenheiten anpassendem Klingenkopf über die Haut, was die Rasur für den Anwender besonders angenehm macht und für gleichmäßige Rasurergebnisse sorgt. Eine gründliche und angenehme Rasur ohne großen Kraftaufwand für den Anwender wird ermöglicht. The invention is based on the idea that a razor is more comfortable and reliable to use for shaving, whose blade head is freely rotatable by means of an arrangement in a ball joint. Thus, the blade head or its razor blade (s) can adapt to skin irregularities particularly well. The blade head adapts flexibly to any bumps or bumps in the skin, thus enabling a particularly thorough and safe shave. The blade head glides gently and with the skin uneven blade head over the skin, which makes the shaving particularly pleasant for the user and ensures even shaving results. A thorough and comfortable shave without much effort for the user is possible.
Als Kugelgelenk wird ein Gelenk bezeichnet, bei dem der Gelenkkopf eine kugelähnliche Form besitzt. Das Gegenstück, das den Kopf in unterschiedlichem Maße umschließt, wird als Kugelgelenkpfanne bzw. Kugelpfanne bezeichnet. Durch diese Geometrie ist ein Kugelgelenk prinzipiell in alle Richtungen beweglich (dreiachsig). Es sind nur rotatorische, nicht je- doch translatorische Bewegungen möglich. Der Griff weist ein Ausrichtungselement in der Kugelgelenkpfanne auf, welches ausgestaltet ist, um in eine Ausnehmung in dem Kugelgelenkkopf einzugreifen. Alternativ oder ergänzend weist der Kugelgelenkkopf ein Ausrichtungselement auf, welches ausgestaltet ist, um in eine Ausnehmung in der Kugelgelenkpfanne einzugreifen. In einer bevorzugten Ausführungsform ist das Ausrichtungselement aus einem elastischen Material gebildet. In einer bevorzugten Ausführungsform ist das Ausrichtungselement ein Stift, welcher formschlüssig in die Ausnehmung greift. Bevorzugt ist das Ausrichtungselement ausgestaltet, um den Gelenkkopf in eine Ausgangsposition zurückzuführen. Das Ausrichtungselement greift dazu in eine Ausnehmung in der Kugeloberfläche, welche soweit in der Gelenkpfanne rotiert werden kann, wie die Elastizität des Ausrichtungselementes es zulässt. Wird der Klingenkopf entlastet, führt die Elastizität des Ausrichtungselementes dazu, dass die Ausnehmung und damit der Gelenkkopf und der Klingenkopf in eine Ausgangsposition zurückgeführt werden. Vorteilhafterweise wird so der Klingenkopf immer wieder in eine Ausgangsposition gegenüber dem Griff gebracht. As a ball joint, a joint is referred to, in which the condyle has a spherical shape. The counterpart, which encloses the head to varying degrees, is referred to as a ball joint socket or ball socket. Due to this geometry, a ball joint is in principle movable in all directions (triaxial). Only rotational, but not translational movements are possible. The handle has an alignment member in the ball joint socket configured to engage a recess in the ball joint head. Alternatively or additionally, the ball joint head has an alignment element, which is designed to engage in a recess in the ball joint socket. In a preferred embodiment, the alignment element is formed of an elastic material. In a preferred embodiment, the alignment element is a pin which engages positively in the recess. Preferably, the alignment member is configured to return the condyle to a home position. The alignment element engages in a recess in the ball surface, which can be rotated as far in the socket as the elasticity of the alignment element allows it. If the blade head is relieved, the elasticity of the alignment element causes the recess and thus the joint head and the blade head are returned to a starting position. Advantageously, the blade head is repeatedly brought into a starting position relative to the handle.
Der erfindungsgemäße Rasierer weist in besonders bevorzugten Ausführungsformen einen um bis zu 360° beweglichen Klingenkopf mit einem Kugelgelenkkopf und einen Griffelement mit einer Gelenkpfanne auf. Die Beweglichkeit des Kugelgelenks ermöglicht eine optimale Anpassung an schwer erreichbare Körperareale wie beispielsweise Knie, oder Knöchel und beugt so Schnittverletzungen vor. Das Kugelgelenk ermöglicht ein einfaches und schnelles Wechseln des Klingenkopfes und besteht bevorzugt aus einem flexiblen Material (z.B. TPE (thermoplastisches Elastomer)). Durch verschiedene Materialien und Elastizitätsgerade des Kugelgelenks, insbesondere des Gelenkkopfes, können verschiedene Druckpunkte in dem Rasierer ermöglicht werden. Dem Anwender ist es zusätzlich möglich, den Grad/Winkel der Flexibilität durch Auflegen des Zeigefingers auf das Kugelgelenk zu variieren und/oder zu fixieren. In particularly preferred embodiments, the razor according to the invention has a blade head which can be moved by up to 360 ° with a ball joint head and a grip element with a joint socket. The flexibility of the ball joint allows optimal adaptation to hard-to-reach areas of the body, such as knees or ankles, thus preventing cuts. The ball joint allows easy and quick change of the blade head and is preferably made of a flexible material (e.g., TPE (thermoplastic elastomer)). Through various materials and elasticity line of the ball joint, in particular the condyle, various pressure points in the razor can be made possible. The user is also possible to vary the degree / angle of flexibility by placing the index finger on the ball joint and / or to fix.
Die unterschiedlichen Flexibilitätslevel/-grade/-winkel im Kugelgelenk ergeben sich bevorzugt aus der Wahl des Material (z.B. unterschiedliche thermoplastische Elastomere) und durch das Einwirken des Anwenders. Der Griff mit Gelenkpfanne besteht bevorzugt aus einem festem, schlagfähigen Material (z.B. ABS (Acrylnitril-Butadien-Styrol)) und kann zudem mit Griffelementen wie aufgerauten Zonen, Riffelung und rutschfesten Materialien verkleidet sein. Der Klingenkopf kann ferner zur Pflege der Haut einen Pflegestrip (Balsamstreifen) mit Emulsionen und pflegenden Ölen enthalten. Der Rasierer gemäß einem Aspekt der vorliegenden Erfindung ist also ein Rasierer mit einem Kugelgelenk zwischen Klingenkopf und Griff. Das bevorzugt um 360° bewegliche Kugelgelenk verbessert durch seine hohe Beweglichkeit die Anpassung des Klingenkopfes an schwerzugängliche Körperregionen. Eine individualisierte Abstimmung des Rasierers auf verschiedene, sensitive Hautpartien kann durch verschiedene Flexibilitätslevel (unterschiedliche Materialien) unterschiedlicher, austauschbarer Klingenköpfe ermöglicht werden. Bevorzugt kann der Gelenkkopf verschiedene Materialien für unterschiedliche Druckpunkte aufweisen. Der Anwender kann vorteilhafterweise selbst den Grad der Beweglichkeit und den auf die Haut wirkenden Druck durch das Auflegen des Zeigefingers (Bremsen des Kugelge- lenkes) bestimmen. The different levels of flexibility / degrees / angles in the ball joint preferably result from the choice of material (eg different thermoplastic elastomers) and from the action of the user. The handle with socket preferably consists of a solid, impact-resistant material (eg ABS (acrylonitrile-butadiene-styrene)) and can also be clad with handle elements such as roughened zones, ribbing and non-slip materials. The blade head may also contain a care strip (balsam strip) with emulsions and nourishing oils for the care of the skin. The razor according to one aspect of the present invention is thus a razor with a ball joint between blade head and handle. The ball joint, which is preferably movable by 360 °, improves the adaptation of the blade head to hard-to-reach body regions due to its high mobility. An individualized adjustment of the razor to different, sensitive skin parts can be made possible by different levels of flexibility (different materials) of different, exchangeable blade heads. Preferably, the condyle may have different materials for different pressure points. The user can advantageously determine even the degree of mobility and the pressure acting on the skin by applying the index finger (braking the ball joint).
Vorteilhaft können durch den rotatorisch frei beweglichen Klingenkopf flexible Rasierbewegungen erreicht werden, die sich an verschiedene zu rasierende Hautareale anpassen. Erfindungsgemäß wird eine besonders sensitive Rasur ermöglicht, bei der nur geringer Druck auf den Rasierer nötig ist und überflüssiger Druck durch die Rotation des Klingenkopfes und die optionale Elastizität des Kugelgelenkes abgefangen wird. Der an dem Kugelgelenk angeordnete Klingenkopf passt sich„wie von selbst" an die Hautoberfläche des Anwenders an. Vorteilhafterweise liegen die Klingen so enger und direkter auf der Haut und für die Rasur ist insgesamt ein geringerer Druck auf den Rasierer erforderlich. Die Flexibilität und Sanftheit der Rasur wird erfindungsgemäß durch geringeren Druck auf den Rasierer und die gegenüber dem Griff flexibel rotierenden Rasierklingen gewährleistet. Die Rasur ist so ergonomisch ansprechend und reduziert das Risiko von Schnittverletzungen. Advantageously, flexible shaving movements can be achieved by the rotatably freely movable blade head, which adapt to different skin areas to be shaved. According to the invention, a particularly sensitive shave is made possible in which only little pressure is required on the razor and superfluous pressure is absorbed by the rotation of the blade head and the optional elasticity of the ball joint. The blade head mounted on the ball joint adapts to the surface of the skin "as if by itself." Advantageously, the blades are so close and more direct to the skin and shaving requires less overall pressure on the shaver According to the invention, shaving is ensured by lower pressure on the razor and the razor blades rotating flexibly with respect to the handle, which makes the shaving more ergonomic and reduces the risk of cuts.
In einer Ausführungsform ist der Kugelgelenkkopf des Klingenkopfes in der Kugelgelenk- pfanne des Griffs lösbar angeordnet. Vorteilhafterweise dient das Kugelgelenk nicht nur einer verbesserten Beweglichkeit des Klingenkopfes gegenüber dem Griff, sonders es ermöglicht auch ein besonders einfaches Austauschen des Klingenkopfes. In one embodiment, the ball joint head of the blade head is detachably arranged in the ball joint socket of the handle. Advantageously, the ball joint is not only an improved mobility of the blade head relative to the handle, but it also allows a particularly simple replacement of the blade head.
In einer Ausführungsform ist der Klingenkopf gegenüber dem Griff in alle drei Richtungen rotatorisch bewegbar. Bevorzugt ist der Klingenkopf um 360° gegenüber dem Griff rotierbar. Dies ermöglicht eine besonders große und flexible Beweglichkeit des Klingenkopfes, wodurch die Sicherheit und Gründlichkeit der Rasur erhöht wird. In one embodiment, the blade head is rotatable relative to the handle in all three directions. Preferably, the blade head is rotatable by 360 ° relative to the handle. This allows a particularly large and flexible mobility of the blade head, whereby the safety and thoroughness of the shave is increased.
In einer Ausführungsform weist der Rasierer ferner ein Bremselement zum Bremsen einer Rotationsbewegung des Kugelgelenkkopfes in der Kugelgelenkpfanne auf. Bevorzugt ist das Bremselement eine Fingerauflagefläche an dem Klingenkopf, auf welcher der Anwender sei- nen Finger auflegen und damit die Position des Klingenkopfes gegenüber dem Griff stabilisieren und damit fixieren (bzw. bremsen) kann. Alternativ oder ergänzend kann das Bremselement eine Ausnehmung in der Gelenkpfanne sein, welche ermöglicht, dass der Anwenden seinen Finger direkt auf einen Oberflächenbereich der Gelenkkugel legt und damit die Position des Klingenkopfes gegenüber dem Griff stabilisiert und damit fixiert (bzw. bremst). Das Bremselement ermöglicht so eine einfache Begrenzung der Auslenkung des Klingenkopfes. In one embodiment, the razor further includes a brake member for braking rotational movement of the ball joint head in the ball joint socket. The brake element is preferably a finger support surface on the blade head, on which the user is seated. Put on a finger and thus stabilize the position of the blade head against the handle and thus fix (or brake) can. Alternatively or additionally, the braking element may be a recess in the socket, which allows the application of his finger placed directly on a surface region of the joint ball and thus stabilizes the position of the blade head relative to the handle and thus (brakes). The brake element thus allows a simple limitation of the deflection of the blade head.
In einer Ausführungsform ist der Kugelgelenkkopf wenigstens teilweise aus einem elasti- sehen Material gebildet. Auch kann bevorzugt sein, dass Teilbereiche des Gelenkkopfes unterschiedliche Elastizitäten aufweisen. Die Unterschiedlichkeit in den Elastizitäten kann beispielweise durch eine geeignete Materialwahl oder durch die Dicke der Materialschicht erreicht werden. Die Teilbereiche können aus demselben Material gefertigt sein, deren Größe variiert oder unterschiedliche Materialien aufweisen. Es kann bevorzugt sein, dass diejenigen Teilbereiche, die näher am Klingenkopf liegen, elastischer als diejenigen Teilbereiche sind, die näher am Griff liegen (oder umgekehrt). Vorteilhaft wird so ermöglicht, dass Hautunebenheiten der Haut des Anwenders besonders gut durch eine geeignete Wahl eines Rasierers mit entsprechendem Elastizitätsverhalten in dem Gelenkkopf abgebildet werden kann. In einer Ausführungsform ist der Klingenkopf über einen Verbindungssteg mit dem Kugelgelenkkopf verbunden. Der Verbindungssteg ermöglicht eine besonders sensitive Auslenkung des Klingenkopfes, da er als eine Art Hebel wirkt und so bereits bei einem relativ kleinen Druck eine Rotation des Klingenkopfes verursacht. In einer alternativen Ausführungsform ist der Klingenkopf direkt (also ohne Verbindungssteg) mit dem Gelenkkopf verbunden. Vorteil- haft kann so für den Anwender eine unmittelbare Kontrolle vom Klingenkopf ermöglicht werden. In one embodiment, the ball joint head is at least partially formed from an elastic material see. It may also be preferred that partial regions of the condyle have different elasticities. The difference in the elasticities can be achieved, for example, by a suitable choice of material or by the thickness of the material layer. The sections may be made of the same material, the size of which varies or different materials. It may be preferred that those portions which are closer to the blade head are more elastic than those portions which are closer to the handle (or vice versa). It is thus advantageously made possible that skin irregularities of the skin of the user can be imaged particularly well by a suitable choice of a razor with a corresponding elastic behavior in the condyle. In one embodiment, the blade head is connected to the ball joint head via a connecting web. The connecting bridge allows a particularly sensitive deflection of the blade head, since it acts as a kind of lever and thus already causes a rotation of the blade head at a relatively small pressure. In an alternative embodiment, the blade head is directly (ie without connecting web) connected to the joint head. Advantageously, an immediate control of the blade head can thus be made possible for the user.
In einer Ausführungsform weist der Klingenkopf eine Spezialklinge und/oder einen Balsamstreifen auf. Vorteilhaft kann der Rasierer um eine oder mehrere Spezialklingen ergänzt sein. Bevorzugt weist der Klingenkopf also unterschiedliche Klingenarten auf, was eine verbesserte, präzisere Rasur in unterschiedlichen Hautbereichen des Anwenders ermöglicht. So können beispielsweise die Rasierklinge(n) des Klingenkopfes für eine großflächige Rasur geeignet sein, welche durch die Verwendung einer oder mehreren kleineren Spezialklinge(n) verfeinert werden kann. Je nach Bedarf können unterschiedliche Klingenköpfe mit unterschiedli- chen Spezialklingen auf dem Rasierer angeordnet werden, wodurch sich die Flexibilität in der Anwendung vorteilhaft erhöht. Ein Balsamstreifen im Sinne der vorliegenden Anmeldung kann ein Streifen sein, welcher beispielsweise eine Rasierseife, eine Feuchtigkeitspflege, ein hautberuhigendes Pflegeprodukt, ein Öl oder dergleichen aufweist. Bevorzugt ist der Balsamstreifen benachbart zu und parallel zu der mindestens einen Rasierklinge und/oder der mindestens eine Spezialrasier- klinge an dem Klingenkopf angeordnet. Vorteilhaft wird erreicht, dass die Haut nicht nur rasiert, sondern auch mit dem Balsamstreifen behandelt und gepflegt wird. In one embodiment, the blade head has a special blade and / or a balsam strip. Advantageously, the razor can be supplemented by one or more special blades. The blade head therefore preferably has different blade types, which allows an improved, more precise shave in different skin areas of the user. For example, the razor blade (s) of the blade head may be suitable for a large-area shave, which may be refined by the use of one or more smaller special blade (s). Depending on requirements, different blade heads with different special blades can be arranged on the razor, which advantageously increases the flexibility in the application. A balsam strip in the sense of the present application may be a strip which has, for example, a shaving soap, a moisturizer, a skin-soothing care product, an oil or the like. The balsam strip is preferably arranged adjacent to and parallel to the at least one razor blade and / or the at least one special razor blade on the blade head. It is advantageously achieved that the skin is not only shaved, but also treated and cared for with the balsam strip.
Vorteilhaft kann durch die Verwendung von ein oder mehreren Spezialklinge(n) und/oder Balsamstreifen am Klingenkopf eine besonders sanfte und gründliche Rasur und Pflege ermöglicht werden. Mit nur einer oder wenigen Bewegungen des Rasierers über den zu rasierenden Hautbereich wird dieser gründliche und sanft rasiert und dabei gleichzeitig gepflegt. Advantageously, the use of one or more special blade (s) and / or balsam strips on the blade head enables a particularly gentle and thorough shaving and care. With only one or a few movements of the razor over the area of the skin to be shaved, it is shaved thoroughly and gently while being cared for.
Je nach Verwendung für unterschiedliche Körperbereiche des Anwenders können Klingen- köpfe mit unterschiedlicher Klingenkopfausgestaltung und -anordnung an dem Kopfende angeordnet werden. Depending on the use for different body areas of the user, blade heads with different blade head configuration and arrangement can be arranged at the head end.
In einer Ausführungsform weist der Griff Griffelemente zum rutschsicheren Halten des Griffs durch den Anwender auf. Bevorzugt ist Griff durch konkave und konvexe Krümmungen und Griffbereiche ergonomisch geformt und weist eine rutschfeste Unterseite auf. Vorteilhaft kann die Handhabung des Rasierers und dessen Halt in der Hand des Anwenders verbessert werden, indem Griffelemente (auch als„Grippelemente" bezeichnet) wie zum Beispiel aufgeraute Bereiche, eine Riffelung, eine Klebefläche, Bereiche eines rutschfesten Materials und/oder konkave/konvexe Wölbungen am Griff vorgesehen sind. Vorteilhaft liegt so der Griff besonders gut in der Hand, eine besonders sichere Handhabung des Rasierers wird ermöglicht und ein„Wegrutschen" des Rasierers wird verhindert. In one embodiment, the handle has gripping elements for non-slip holding of the handle by the user. Preferably, the handle is ergonomically shaped by concave and convex curvatures and gripping areas and has a non-slip underside. Advantageously, the handling of the razor and its grip in the user's hand can be improved by gripping elements (also referred to as "gripping elements") such as roughened areas, a corrugation, an adhesive surface, areas of non-slip material and / or concave / convex curvatures Advantageously, the handle is particularly well in the hand, a particularly safe handling of the razor is possible and a "slipping" of the razor is prevented.
In einer Ausführungsform ist der Griff konkav oder konvex entlang der Längsachse des Rasierers geformt. Ferner kann bevorzugt sein, dass der Griff in einer leicht gebogenen Form beschrieben ist und aus festem, schlagfähigen Material (z.B. ABS (Acrylnitril-Butadien-In one embodiment, the handle is concave or convex along the longitudinal axis of the razor. Further, it may be preferred that the handle is described in a slightly curved shape and made of strong, impactable material (e.g., ABS (acrylonitrile butadiene)).
Styrol)) besteht. Ein konvex gekrümmter Griff lässt sich ergonomisch besonders angenehmer und auch für die Rasur zuverlässig verwenden, da der der konkav gewölbten Handinnenfläche angepasste Griff eine besonders ergonomische Handhabung ermöglicht. Eine konvexe Griffform hingegen kann besonders vorteilhaft sein, um sensibel Druck auf das Ge- lenkpfannenende des Griffs und so auf den zu rasierenden Hautbereich aufbringen zu können. In einer Ausführungsform weist der Klingenkopf eine Vielzahl von Rasierklinge(n) auf. Die Rasierklinge(n) ist/sind an einer Unterseite des Rasierers angeordnet, welche bei bestimmungsgemäßem Gebrauch des Rasierers über die Haut des Anwenders gleitet, um die Ra- sur aufzuführen. Durch die erfindungsgemäße Anordnung von Rasierklinge(n) an dem gegenüber dem Griff rotierbarem Klingenkopf wird eine besonders sanfte und gründliche Rasur ermöglicht, da sich der rotierbarem Klingenkopf den Unebenheiten der Hautoberfläche besonders geschmeidig anpasst. Der erfindungsgemäße Rasierer eignet sich aufgrund seiner flexiblen Einsatzmöglichkeiten vorteilhafterweise zur Teil- oder Ganzkörperrasur und insbesondere zur Rasur unter Dusche. Styrene)). A convex curved handle makes it ergonomically more comfortable and also reliable for shaving, as the handle, which is adapted to the concave curved palm, allows a particularly ergonomic handling. By contrast, a convex handle shape can be particularly advantageous in order to be able to exert sensitive pressure on the joint pan end of the handle and thus on the skin area to be shaved. In one embodiment, the blade head has a plurality of razor blade (s). The razor blade (s) is / are disposed on an underside of the razor which, when used properly, slides over the skin of the user to perform the raking. The arrangement according to the invention of the razor blade (s) on the blade head which is rotatable relative to the handle makes possible a particularly gentle and thorough shaving, since the rotatable blade head adapts particularly smoothly to the unevenness of the skin surface. The razor according to the invention is due to its flexible use advantageously for partial or full body shaving and especially for shaving under shower.
In einem alternativen Aspekt, weist ein Rasierer einen Griff, an dessen einen Ende ein Kugelgelenkkopf angeordnet ist, und einen Klingenkopf mit mindestens einer Rasierklinge und einer Kugelgelenkpfanne, wobei der Kugelgelenkkopf des Griffs und die Kugelgelenkpfanne des Klingenkopfes ein Kugelgelenk bilden. Der Rasierer weist ferner ein Ausrichtungselement in der Kugelgelenkpfanne oder an dem Kugelgelenkkopf auf, welches ausgestaltet ist, um in eine Ausnehmung in dem Kugelgelenkkopf oder der Kugelgelenkpfanne einzugreifen. In einem weiteren Aspekt kann der Rasierer anstelle eines Kugelgelenkes ein Nussgelenk aufweisen. Die vorliegend beschriebenen Ausführungsformen gelten in analoger Weise auch für diese Aspekte. In an alternative aspect, a razor includes a handle having a ball joint head disposed at one end thereof and a blade head having at least one razor blade and a ball joint socket, the ball joint head of the handle and the ball joint socket of the blade head forming a ball joint. The razor further includes an alignment member in the ball joint socket or ball joint head configured to engage a recess in the ball joint head or ball joint socket. In another aspect, the razor may have a nut joint instead of a ball and socket joint. The embodiments described herein apply analogously to these aspects as well.
In einem weiteren Aspekt bezieht sich die Erfindung auf ein Verfahren zum Herstellen eines Rasierers der vorliegenden Erfindung, mit den Schritten: Vorsehen eines Griffs mit einer Ku- gelgelenkpfanne an dessen einem Ende, Vorsehen eines Ausrichtungselementes in der Kugelgelenkpfanne, Vorsehen eines Klingenkopfes mit mindestens einer Rasierklinge und einem Kugelgelenkkopf, und Vorsehen einer Ausnehmung in dem Kugelgelenkkopf, wobei der Kugelgelenkkopf des Klingenkopfes und die Kugelgelenkpfanne des Griffs ausgestaltet sind, um ein Kugelgelenk bilden, und das Ausrichtungselement ausgestaltet ist, um in die Aus- nehmung einzugreifen. In another aspect, the invention relates to a method of manufacturing a razor of the present invention comprising the steps of: providing a handle with a ball joint socket at one end thereof, providing an alignment member in the ball joint socket, providing a blade head with at least one razor blade and a ball joint head, and providing a recess in the ball joint head, wherein the ball joint head of the blade head and the ball joint socket of the handle are configured to form a ball joint, and the alignment member is configured to engage the recess.
Die vorstehend beschriebenen Ausführungsformen können beliebig miteinander und mit den vorstehend beschriebenen Aspekten kombiniert werden, um erfindungsgemäße Vorteile zu erreichen. Im Folgenden werden bevorzugte Kombinationen von Ausführungsformen bei- spielhaft beschrieben, wobei: Figuren 1 a bis 1 d eine Ausführungsform eines erfindungsgemäßen Rasierers zeigen;The embodiments described above may be combined as desired with one another and with the aspects described above in order to achieve advantages according to the invention. In the following, preferred combinations of embodiments are described by way of example, wherein: Figures 1 a to 1 d show an embodiment of a razor according to the invention;
Figuren 2a bis 2d Detailansicht des Kugelgelenkes und der Klingenköpfe der Ausführungsform der Figur 1 zeigen; Figures 2a to 2d show detailed view of the ball joint and the blade heads of the embodiment of Figure 1;

Figur 6 die Rotationsbeweglichkeit verdeutlicht.  Figure 6 illustrates the rotational mobility.
Figuren 1 a und 1 b zeigen perspektivische Ansichten eines Rasierer 1 von oben, und Figuren 1 c und 1 d zeigen eine Draufsicht. Figures 1 a and 1 b show perspective views of a razor 1 from above, and Figures 1 c and 1 d show a plan view.
Der Rasierer 1 weist einen Griff 10 zum Anliegen in der Hand des Anwenders sowie einen Klingenkopf 20 auf. An demjenigen Ende des Griffs 10, welches dem Kopfende zugewandt ist, ist eine Kugelgelenkpfanne 1 1 angeordnet. Der Klingenkopf 20 weist Rasierklingen 21 sowie einen an einem Verbindungssteg 35 angeordneten Kugelgelenkkopf 22 auf, der in der Kugelgelenkpfanne 1 1 des Griffs 10 angeordnet ist und so mit diesem ein Kugelgelenk bildet, welches beispielsweise die in Figuren 1 c und 1 d dargestellte Rotation des Klingenkopfes 20 gegenüber dem Griff 10 ermöglicht. The razor 1 has a handle 10 for abutment in the user's hand and a blade head 20. At that end of the handle 10, which faces the head end, a ball joint socket 1 1 is arranged. The blade head 20 has razor blades 21 and arranged on a connecting web 35 ball joint head 22 which is disposed in the ball joint socket 1 1 of the handle 10 and thus forms with this a ball joint, which, for example, the rotation of the blade head shown in Figures 1 c and 1 d 20 relative to the handle 10 allows.
Der Griff 10 kann Griffelemente (nicht dargestellt) aufweisen, welche ein rutschsicheres Halten des Griffs durch den Anwender ermöglichen. Der Kugelgelenkkopf 22 kann aus einem elastischen Material geformt sein, um eine federnde Wirkung des Klingenkopfes 20 zu erreichen. Der Klingenkopf 20 weist zusätzlich zu den Rasierklingen 21 Balsamstreifen 24 und 25 zum Pflegen der Haut auf. The handle 10 may comprise handle elements (not shown), which allow a non-slip hold of the handle by the user. The ball joint head 22 may be formed of an elastic material to achieve a resilient action of the blade head 20. The blade head 20 has, in addition to the razor blades 21, balsam strips 24 and 25 for the care of the skin.
Figur 2a illustriert die Lösbarkeit des Klingenkopfes 20 vom dem Griff 10, indem der Gelenkkopf 22 aus der Gelenkpfanne 1 1 entfernt wird, um einen neuen Klingenkopf 20 einzusetzen, wenn die Rasierklingen 21 beispielsweise stumpf geworden sind oder ein Klingenkopf 20 mit andersartigen Rasierklingen 21 , Spezialklingen (nicht dargestellt) oder Balsamstreifen 24, 25 verwendet werden soll. Figure 2a illustrates the releasability of the blade head 20 from the handle 10 by removing the condyle 22 from the socket 1 1 to insert a new blade head 20 when the razor blades 21 have become blunt, for example, or a blade head 20 with other razor blades 21, special blades (not shown) or balsam strips 24, 25 to be used.
Der Austausch der Klingenköpfe ist in Abhängigkeit des Materials der Kugelgelenke möglich. Bei einem relativ elastischem Material ist die Anbringung eines Klingenkopfes durch Aufprellen in die Kugelgelenkpfanne möglich um eine schlüssige Verbindung wieder herzustellen. The replacement of the blade heads is possible depending on the material of the ball joints. In a relatively elastic material, the attachment of a blade head through Bouncing in the ball joint socket possible to restore a coherent connection.
Figur 2a illustriert ferner ein Ausrichtungselement 14 (Ausrichtungsstift), welcher in der Ge- lenkpfanne 1 1 (welche durchsichtig dargestellt ist, um den Ausrichtungsstift 14 zu zeigen) vorgesehen ist und in eine Ausnehmung 36 in der Oberfläche des Gelenkkopfes 22 greift. Der Ausrichtungsstift 14 ist elastisch und erlaubt daher eine Rotation des Klingenkopfes 20, wenn der Klingenkopf 20 mit dem Rasierdruck auf die Haut beaufschlagt wird. Der Klingenkopf 20 wird mittels des Ausrichtungsstiftes 14 wieder in die Ausgangsposition zurückgeführt, sobald er keiner Belastung (kein Rasierdruck) mehr ausgesetzt ist. Figuren 2b bis 2d zeigen perspektivische Ansichten des Klingenkopfes 20. FIG. 2 a further illustrates an alignment element 14 (alignment pin) provided in the joint socket 1 1 (which is shown in a transparent manner to show the alignment pin 14) and engages in a recess 36 in the surface of the joint head 22. The alignment pin 14 is elastic and therefore allows rotation of the blade head 20 when the blade head 20 is subjected to shaving pressure on the skin. The blade head 20 is returned by means of the alignment pin 14 back to the starting position as soon as it is no longer exposed to stress (no shaving pressure). FIGS. 2b to 2d show perspective views of the blade head 20.
Figuren 3 und 4 illustrieren Ausführungsformen eines Bremselementes 37. Soweit die Merkmale der Figuren 3 und 4 mit denen der zuvor beschriebenen Ausführungsformen überein- stimmen, wird auf die vorstehend beschriebenen Merkmale verwiesen. FIGS. 3 and 4 illustrate embodiments of a brake element 37. Insofar as the features of FIGS. 3 and 4 correspond to those of the previously described embodiments, reference is made to the features described above.
Figur 3a illustriert eine Ausführungsform eines Bremselementes 37, welches als Auflagefläche für einen Finger des Anwenders ausgestaltet ist. Soweit die Merkmale der Figur 3a mit denen der zuvor beschriebenen Ausführungsformen übereinstimmen, wird auf die vorste- hend beschriebenen Merkmale verwiesen. Das Bremselement 37 ist in Verlängerung desFIG. 3a illustrates an embodiment of a brake element 37, which is configured as a support surface for a finger of the user. Insofar as the features of FIG. 3a correspond to those of the previously described embodiments, reference is made to the features described above. The brake element 37 is in extension of the
Verbindungssteges 35 auf der Oberfläche der Klingenkopfes 20 vorgesehen. Wie in Figur 3b gezeigt, legt der Anwender bei bestimmungsgemäßem Gebrauch des Rasierer 1 seinen Finger auf dem Bremselement 37 ab, während er den Rasierer 1 ab Griff 10 festhält. Dadurch stellt die Hand des Anwenders eine die Auslenkung des Klingenkopfes 20 fixierende Verbin- dung zwischen Griff 10 und Klingenkopf 20 her, was zu einem„Bremsen" bzw. Feststellen der Auslenkung des Klingenkopfes 20 führt. Connecting web 35 provided on the surface of the blade head 20. As shown in Figure 3b, the user places his finger on the brake element 37 when the razor 1 is used as intended, while holding the razor 1 from the handle 10 onwards. As a result, the user's hand establishes a connection between the handle 10 and the blade head 20 which fixes the deflection of the blade head 20, which leads to a "braking" or detection of the deflection of the blade head 20.
Figur 4 illustriert eine Ausführungsform eines Bremselementes 37, welches als Ausnehmung in der Gelenkpfanne 1 1 ausgestaltet ist. Der Anwender legt bei bestimmungsgemäßem Ge- brauch des Rasierer 1 seinen Finger auf dem Gelenkkopf 22, dessen Oberfläche teilweise in der Ausnehmung 22 zugänglich ist, ab, während er den Rasierer 1 ab Griff 10 festhält. Dadurch stellt die Hand des Anwenders eine die Auslenkung des Klingenkopfes 20 fixierende Verbindung zwischen Griff 10 und Klingenkopf 20 her, was zu einem„Bremsen" bzw. Feststellen der Auslenkung des Klingenkopfes 20 führt. Figur 5 illustriert eine weitere Ausführungsform eines Rasierers 1. Die Ausführungsform der Figur 5 unterscheidet sich von den zuvor beschriebenen Ausführungsformen im Wesentlichen in der Ausgestaltung des Klingenkopfes 20. Der Klingenkopf 20 der Figur 5 weist keinen Verbindungssteg 35 auf, sondern ist direkt an dem Kugelgelenkkopf 22 angeordnet. FIG. 4 illustrates an embodiment of a brake element 37, which is designed as a recess in the socket 1 1. When the razor 1 is used as intended, the user places his finger on the joint head 22, whose surface is partially accessible in the recess 22, while holding the razor 1 from the grip 10. As a result, the user's hand establishes a connection between the handle 10 and the blade head 20 which fixes the deflection of the blade head 20, which leads to a "braking" or locking of the deflection of the blade head 20. FIG. 5 illustrates another embodiment of a razor 1. The embodiment of FIG. 5 differs from the previously described embodiments substantially in the design of the blade head 20. The blade head 20 of FIG. 5 has no connecting web 35, but is directly on the ball joint head 22 arranged.
Der Rasierer 1 weist, wie in Figur 5 und 6 durch die Pfeile illustriert, einen um 360° beweglichen Klingenkopf 20 mit einem Kugelgelenkkopf 22 und einem Griff 10 mit einer Gelenkpfanne 1 1 auf. Der Klingenkopf 20 ist gegenüber dem Griff so in alle drei Richtungen rotatorisch bewegbar. Die Beweglichkeit des Kugelgelenks 1 1 , 22 ermöglicht eine optimale Anpassung an schwer erreichbare Körperareale (Knie, Knöchel) und beugt so Schnittverletzungen vor. Das Kugelgelenk 1 1 , 22 ist gleichzeitig das Wechselelement für den Klingenkopf 20 und besteht aus einem flexiblen Material (z.B. TPE (thermoplastisches Elastomer)). Durch verschiedene Materialien und Elastizitätsgerade des Kugelgelenks 1 1 , 22 können verschiedene Druckpunkte in den Rasierer 1 eingebracht werden. Dem Anwender ist es zusätzlich möglich, den Grad/Winkel der Flexibilität durch Auflegen des Zeigefingers auf das Kugelgelenk 1 1 , 22, zu variieren und/oder zu fixieren. The razor 1 has, as illustrated by the arrows in FIGS. 5 and 6, a blade head 20 which is movable by 360 ° and has a ball joint head 22 and a handle 10 with a joint socket 1 1. The blade head 20 is rotatable relative to the handle in all three directions. The mobility of the ball joint 1 1, 22 allows optimal adaptation to difficult to reach areas of the body (knee, ankle) and thus prevents cuts. The ball joint 1 1, 22 is at the same time the change element for the blade head 20 and consists of a flexible material (for example TPE (thermoplastic elastomer)). By different materials and elasticity line of the ball joint 1 1, 22 different pressure points can be introduced into the razor 1. The user is also possible to vary the degree / angle of flexibility by placing the index finger on the ball joint 1 1, 22, and / or to fix.
Die unterschiedlichen Flexibilitätslevel im Kugelgelenk 1 1 , 22 ergeben sich aus der Wahl des Material (unterschiedliche thermoplastische Elastomere) und durch das Einwirken des An- wenders. Der Griff 10 mit Gelenkpfanne 1 1 besteht aus festem, schlagfähigen Material (z.B. ABS (Acrylnitril-Butadien-Styrol)) und kann zudem mit Grippelementen wie aufgerauten Zonen, Riffelung und rutschfesten Materialien verkleidet sein. The different levels of flexibility in the ball joint 1 1, 22 result from the choice of material (different thermoplastic elastomers) and by the action of the user. The handle 10 with socket 1 1 is made of strong, impactable material (e.g., ABS (acrylonitrile-butadiene-styrene)) and may also be clad with gripping elements such as roughened zones, ribbing, and non-slip materials.
Der Klingenkopf 20 kann zur Pflege der Haut einen Pflegestrip (Balsamstreifen) mit Emulsio- nen und pflegenden Ölen enthalten. The blade head 20 may contain a care strip (balsam strip) with emulsions and nourishing oils for the care of the skin.
Der Rasierer 1 mit 360° beweglichem Kugelgelenk 1 1 , 22 verbessert durch seinen erhöhte Beweglichkeit die Anpassung des Klingenkopfes 20 an schwer zugängliche Körperregionen. Die individuelle Abstimmung des Rasierers 1 auf verschiedene, sensitive Hautpartien kann durch mehrere Flexibilitätslevel (unterschiedliche Materialien) und unterschiedliche Klingenköpfe 20 gewährleistet werden. Der Anwender kann zudem selbst den Grad der Beweglichkeit durch das Auflegen des Zeigefingers bestimmen. The razor 1 with 360 ° movable ball joint 1 1, 22 improved by its increased mobility, the adaptation of the blade head 20 to hard to reach areas of the body. The individual vote of the razor 1 on different, sensitive skin parts can be ensured by several levels of flexibility (different materials) and different blade heads 20. The user can also determine the degree of agility by hanging up the index finger.
Die Flexibilitäten der Aufhängung des Kugelgelenks, der Materialien des Griffs und/oder des Klingenkopfes sind weitere Einflussfaktoren, die eine individuelle Rasur ermöglichen. Ähnlich den Aufhängungen von Zahnbürstenköpfen kann mittels unterschiedlich biegsamer Aufhängungen erfindungsgemäß auch der Klingenkopf bzw. das Kugelgelenk eine weiche, mittlere oder harte Druckausübung erzielt werden. Der Anwender kann sich dann je nach seinen Bedürfnissen entsprechende Rasierer auswählen. The flexibility of the suspension of the ball joint, the materials of the handle and / or the blade head are other influencing factors that allow an individual shave. Similar to the suspensions of toothbrush heads, by means of differently flexible suspensions according to the invention, the blade head or the ball joint can also be given a soft, medium or hard pressure application. The user can then select appropriate razors according to his needs.
