Description

Die Erfindung betrifft einen am vorderen Ende eines Handgriffs angeordneten Rasierapparatekopf, insbesondere Rasierklingeneinheit eines Naßrasierapparates, bei dem in einem Kunststoffgehäuse eine Einfach- oder Doppelrasierklinge federnd angeordnet 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 resiliently arranged in a plastic housing.

Bei Einwegnaßrasierapparaten ist eine Einfach- oder Doppelrasierklinge unlösbar im Rasierapparatekopf in einem Kunststoffgehäuse eingebettet. Ist der Rasierapparatekopf separat ausgebildet und kann an einem Handgriff befestigt werden, wobei zu diesem Zweck der Handgriff sowie der Rasierapparatekopf miteinander korrespondierende Verriegelungseinrichtungen aufweisen, spricht man von einer sogenannten Rasierklingeneinheit.With disposable wet shavers, a single or double razor blade is embedded in the shaver head in a plastic housing. If the razor head is designed separately and can be attached to a handle, for which purpose the handle and the razor head have interlocking devices that correspond to one another, this is referred to as a so-called razor blade unit.

Bei einer bekannten Rasierklingeneinheit eines Naßrasierapparates ist ein Kunststoffgehäuse mit einer vorderen Führungsleiste vorgesehen. Innerhalb dieses Kunststoffgehäuses sind zwei Rasierklingen zur Bildung einer Doppelrasierklinge für sich jeweils federnd angeordnet. Zu diesem Zweck liegen die beiden Rasierklingen jeweils auf seitlichen Federzungen auf, so daß sie sich während der Rasur jeweils der Gesichtskontur anpassen können.In a known razor blade unit of a wet shaver, a plastic housing with a front guide bar is provided. Within this plastic housing two razor blades are each resiliently arranged to form a double razor blade. For this purpose, the two razor blades each rest on lateral spring tongues so that they can adapt to the contour of the face during the shave.

Ein Nachteil bei diesem bekannten System ist, daß der Winkel und damit die Anstellung der Rasierklingen während der Rasur nicht konstant bleibt. Es können dabei unerwünschte Schwingungen oder Bewegungen in der jeweiligen Rasierklinge auftreten, die Ursache unbefriedigender Schnittleistungen sein können.A disadvantage of this known system is that the angle and thus the setting of the razor blades does not remain constant during the shave. Undesired vibrations or movements can occur in the respective razor blade, which can be the cause of unsatisfactory cutting performance.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Rasierapparatekopf, insbesondere Rasierklingeneinheit eines Naßrasierapparates mit einer verbesserten Federlagerung der Einfach- oder Doppelrasierklingen 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 spring mounting of the single or double razor blades.

Als technische Lösung wird mit der Erfindung vorgeschlagen, daß die Einfach- oder Doppelrasierklinge an einem Klingenblock befestigt ist, der entgegen der Federkraft in Richtung Rückwand des Kunststoffgehäuses in diesem verschiebbar gelagert ist.As a technical solution it is proposed with the invention that the single or double razor blade is attached to a blade block which is mounted against the spring force in the direction of the rear wall of the plastic housing in the latter.

Ein nach dieser technischen Lehre ausgebildeter Rasierapparatekopf, insbesondere Rasierklingeneinheit eines Naßrasierapparates mit der auf einem Klingenblock befestigten Einfach- oder Doppelrasierklinge hat den Vorteil einer verbesserten Federaufhängung. So sind bei der Verwendung der üblichen Doppelrasierklinge die beiden parallel zueinander befestigten Einzelrasierklingen parallel und damit synchron verschiebbar. Der entscheidende Vorteil dieses Systems ist, daß der Winkel und damit die Anstellung die Rasierklingen während der Rasur konstant bleibt und aufgrund der präzisen technischen Führung unerwünschte Schwingungen oder Bewegungen in der Klinge vermieden werden, so daß damit optimale Schnittleistungen erzielt werden können. Die Rasierklingen bleiben somit während der Rasur bei der linearen Verschiebebewegung in konstantem Winkel zueinander, was trotz der Federlagerung zu dem sehr guten Schnittergebnis führt. Unter der linearen Führung ist dabei nicht nur zu verstehen, daß der Klingenblock eine exakte Linearbewegung ausführt, indem dieser gleichmäßig sowohl auf der linken als auch auf der rechten Seite in Richtung Rückwand des Kunststoffgehäuses verschoben wird, es ist gleichermaßen darunter auch zu verstehen, daß der Klingenblock nur an einem der beiden Enden in Richtung Rückwand des Kunststoffgehäuses verschoben wird und dabei gewissermaßen eine Verschwenkbewegung in der Ebene der Rasierklinge ausführt, wobei der Drehpunkt das andere Ende des Klingenblocks bildet. Insgesamt kann somit die Bewegung des Klingenblocks parallel oder unparallel erfolgen. Dies bietet den Vorteil, daß in Abhängigkeit von angreifenden Rasierkräften ein leichtes Auslenken des Klingenblocks sichergestellt ist. Der Klingenblock kann aus Kunststoff oder Metall bestehen. Er kann einteilig oder mehrteilig sein. Die Rasierklingen sind dabei auf dem Klingenblock mit einer den Belastungen bei der Rasur auftretenden widerstehenden Verbindungsmethode befestigt, beispielsweise durch Kleben, Schweißen, Reibschluß, Formschluß oder Nieten.A razor head designed according to this technical teaching, in particular a razor blade unit of a wet razor with the single or double razor blade attached to a blade block, has the advantage of an improved spring suspension. Thus, when using the usual double razor blade, the two individual razor blades fastened parallel to one another can be moved parallel and thus synchronously. The decisive advantage of this system is that the angle and thus the position of the razor blades remains constant during shaving and because of the precise technical guidance, undesirable vibrations or movements in the blade are avoided, so that optimal cutting performance can be achieved. The razor blades thus remain at a constant angle to one another during the shaving with the linear displacement movement, which is very good despite the spring bearing Cutting result leads. Under the linear guide is not only to be understood that the blade block performs an exact linear movement by moving it equally on both the left and on the right side towards the rear wall of the plastic housing, it is equally to be understood that the Blade block is shifted only at one of the two ends in the direction of the rear wall of the plastic housing and, as it were, executes a pivoting movement in the plane of the razor blade, the fulcrum forming the other end of the blade block. Overall, the blade block can thus move in parallel or non-parallel. This offers the advantage that a slight deflection of the blade block is ensured depending on the shaving forces acting on it. The blade block can be made of plastic or metal. It can be in one part or in several parts. The razor blades are fastened to the block of blades with a resistant connection method that can withstand the stresses of shaving, for example by gluing, welding, friction locking, positive locking or riveting.

In einer bevorzugten Weiterbildung wird vorgeschlagen, daß der Klingenblock parallel zu der (den) Ebene(n) der Rasierklinge(n) verschiebbar ist. Dadurch ist ein parallel horizontal beweglicher Klingenblock geschaffen, wobei die auf dem Klingenblock befestigten Rasierklingen parallel unter dem einmal gewählten Anstellwinkel zur Gesichtstangente nach hinten verschiebbar ist. Dadurch wird ein optimales Schnittergebnis bei einer federnden Lagerung der Rasierklingen erzielt.In a preferred development it is proposed that the blade block can be displaced parallel to the plane (s) of the razor blade (s). As a result, a parallel horizontally movable blade block is created, the razor blades attached to the blade block being displaceable parallel to the face tangent at the selected angle of attack. This ensures an optimal cutting result when the razor blades are spring loaded.

Um eine präzise Führung des Klingenblocks zu erzielen, ist die Verschiebebewegung des Klingenblocks oberseitig durch eine Abdeckkappe des Kunststoffgehäuses geführt.In order to achieve precise guidance of the blade block, the sliding movement of the blade block is guided through a cover cap of the plastic housing on the upper side.

Zur Ausbildung einer optimalen Federlagerung wird vorgeschlagen, daß zwischen dem Klingenblock und der Rückwand des Kunststoffgehäuses eine Druckfeder angeordnet ist. Diese zwischen der Rückwand des Kunststoffgehäuses und dem Klingenblock abgestützte Druckfeder gewährleistet die erforderliche Rückstellkraft für den Klingenblock.To form an optimal spring mounting, it is proposed that a compression spring be arranged between the blade block and the rear wall of the plastic housing. This compression spring, supported between the rear wall of the plastic housing and the blade block, ensures the necessary restoring force for the blade block.

Vorzugsweise ist die Druckfeder eine gewölbte Blatt- oder Drahtfeder. Diese kann aus Kunststoff oder Metall bestehen und ist entsprechend in das Kunststoffgehäuse eingelegt, daß sie zwischen der Rückwand des Kunststoffgehäuses und dem Klingenblock abgestützt ist. Dabei kann die Blatt- oder Drahtfeder in einer Weiterbildung über ihre Länge mehrfach gewölbt sein. Darunter ist zu verstehen, daß sich eine Wölbung an die andere anschließt, so daß mehrere Anlagepunkte an der Rückwand des Kunststoffgehäuses einerseits und an dem Klingenblock andererseits vorgesehen sind. Dies hat zum einen den Vorteil einer gleichmäßigen Druckbeaufschlagung über die Länge des Klingenblocks, zum anderen können dadurch die zuvor bereits beschriebenen einseitigen Verschiebebewegungen durchgeführt werden.The compression spring is preferably a curved leaf or wire spring. This can consist of plastic or metal and is correspondingly inserted into the plastic housing so that it is supported between the rear wall of the plastic housing and the blade block. In one development, the leaf or wire spring can be curved several times over its length. This means that one curvature adjoins the other, so that several contact points are provided on the rear wall of the plastic housing on the one hand and on the blade block on the other. On the one hand, this has the advantage of a uniform application of pressure over the length of the blade block, and on the other hand, the one-sided displacement movements already described can thereby be carried out.

Alternativ zu dem zuvor Gesagten kann die Rückstellkraft auch durch einen im Apparat befindlichen federnden Nocken aufgebracht werden, welcher gleichermaßen eine Federlagerung des Klingenblocks gewährleistet.As an alternative to what has been said above, the restoring force can also be applied by a resilient cam located in the apparatus, which likewise ensures spring mounting of the blade block.

In einer bevorzugten Weiterbildung des Klingenblocks weist dieser seitlich jeweils eine Führungsschiene auf, mittels welchen der Klingenblock in entsprechenden Ausnehmungen im Kunststoffgehäuse verschiebbar ist. Durch diese Führungsschienen weist das System einwandfreie Führungseigenschaften auf. Dabei können die Führungsschienen durch das Kunststoffgehäuse, insbesondere durch eine obere Klingenschale nach außen geführt sein. Dadurch kann die Funktion überprüft werden. Auch kann zwecks Reinigung der Klingenblock nach hinten geschoben werden.In a preferred development of the blade block, the blade block laterally has a guide rail, by means of which the blade block can be displaced in corresponding recesses in the plastic housing. Thanks to these guide rails, the system has flawless guiding properties. The guide rails can be guided outwards through the plastic housing, in particular through an upper blade shell be. This enables the function to be checked. The blade block can also be pushed back for cleaning.

Eine Weiterbildung der Führungsschienen schlägt vor, daß diese außenseitig konvex gewölbt sind. Die Wölbung ist dabei derart ausgebildet und hat den Zweck, daß damit die einseitige Verschiebebewegung in Form der bereits zuvor beschriebenen Verschwenkbewegung in der Ebene der Rasierklingen ermöglicht wird, indem eine einseitig angreifende Kraft auch zu einer einseitig auslenkbaren Bewegung führt.A further development of the guide rails suggests that they are convexly curved on the outside. The curvature is designed in such a way and has the purpose that the one-sided displacement movement in the form of the previously described pivoting movement in the plane of the razor blades is made possible in that a force acting on one side also leads to a movement that can be deflected on one side.

Eine bevorzugte Weiterbildung des Rasierapparatekopfes insbesondere in Form der Rasierklingeneinheit schlägt vor, daß das Kunststoffgehäuse aus einem zusammensetzbaren Unterteil und Oberteil besteht, zwischen denen der Klingenblock als separates Bauteil angeordnet ist. Dies bringt den Vorteil mit sich, daß die Rasierklingeneinheit auf technisch einfache Weise aufgebaut und entsprechend einfach montiert werden kann. Das Oberteil des Kunststoffgehäuses ist dabei vorzugsweise rahmenartig ausgebildet, indem eine vordere Führungsleiste und eine hintere Abdeckkappe unter Belassung eines Zwischenabstandes durch Seitenwände fest miteinander verbunden sind.A preferred further development of the razor head, in particular in the form of the razor blade unit, proposes that the plastic housing consists of an assembled lower part and upper part, between which the blade block is arranged as a separate component. This has the advantage that the razor blade unit can be constructed in a technically simple manner and can be assembled correspondingly easily. The upper part of the plastic housing is preferably designed in a frame-like manner in that a front guide strip and a rear cover cap are firmly connected to one another with side walls leaving an intermediate distance.

In einer bevorzugten Weiterbildung des Unterteils weist dieses Durchbrechungen auf. Diese haben den Vorteil, daß während der Rasur der Rasierschaum besser abgeführt werden kann und daß darüber hinaus die Reinigung der Rasierklingeneinheit verbessert wird.In a preferred development of the lower part, it has openings. These have the advantage that the shaving foam can be better removed during shaving and that the cleaning of the razor blade unit is also improved.

Schließlich wird in einer Weiterbildung vorgeschlagen, daß der Klingenblock wenigstens einen Nocken aufweist, der durch eine Öffnung im Kunststoffgehäuse nach außen geführt ist. Vorzugsweise weist dabei der Klingenblock seitlich jeweils einen Nocken auf, die durch entsprechende Öffnungen in den Seitenwänden des Kunststoffgehäuses nach außen geführt sind. Mit diesen Nocken kann der Klingenblock von außen leicht betätigt werden, wodurch das Reinigen der Rasierklingen wesentlich verbessert wird.Finally, it is proposed in a further development that the blade block has at least one cam which is guided to the outside through an opening in the plastic housing. Preferably the blade block has a cam on each side, which is guided to the outside through corresponding openings in the side walls of the plastic housing. With these cams, the blade block can be easily operated from the outside, which considerably improves the cleaning of the razor blades.

Die Rasierklingeneinheit besteht aus einem Kunststoffgehäuse 1. Dieses setzt sich zusammen aus einem Unterteil 2 und einem Oberteil 3, wobei das Unterteil 2 im Bodenbereich Durchbrechungen 4 aufweist. Das Unterteil 2 und das Oberteil 3 können durch unterschiedlichste Möglichkeiten fest miteinander verbunden werden, beispielsweise durch Verschweißen, Verkleben, Verrasten, Ineinanderstecken etc.The razor blade unit consists of a plastic housing 1. This is composed of a lower part 2 and an upper part 3, the lower part 2 having openings 4 in the base area. The lower part 2 and the upper part 3 can be firmly connected to one another by a wide variety of possibilities, for example by welding, gluing, locking, plugging into one another, etc.

Innerhalb des Kunststoffgehäuses 1 ist ein Klingenblock 5 verschiebbar gelagert. Dieser Klingenblock 5 ist mit zwei Rasierklingen 6 zur Bildung einer Doppelrasierklinge ausgestattet, die fest mit dem Klingenblock 5 verbunden sind. Der Klingenblock 5 mit seinen Rasierklingen 6 ist dabei auf dem Boden des Unterteils 2 verschiebbar gelagert. Oberseitig ist der Klingenblock 5 durch eine hintere Abdeckkappe 7 des Oberteils 3 des Kunststoffgehäuses 1 geführt. Für die weitere Führung weist der Klingenblock 5 seitlich jeweils eine Führungsschiene 8 auf, welche in einer entsprechenden Ausnehmung 9 im Kunststoffgehäuse 1 verschiebbar geführt sind. Fig. 2 läßt dabei erkennen, daß die beiden Führungsschienen 8 außenseitig leicht konvex gewölbt sind.A blade block 5 is slidably mounted within the plastic housing 1. This blade block 5 is equipped with two razor blades 6 to form a double razor blade, which are firmly connected to the blade block 5. The blade block 5 with its razor blades 6 is slidably mounted on the bottom of the lower part 2. The top of the blade block 5 is guided through a rear cap 7 of the upper part 3 of the plastic housing 1. For further guidance, the blade block 5 has a guide rail 8 on each side, which are guided in a corresponding recess 9 in the plastic housing 1. Fig. 2 shows that the two guide rails 8 are slightly convex on the outside.

Die Schnittdarstellungen in Fig. 6 und 7 lassen erkennen, daß der Klingenblock 5 unterseitig eine Leiste 10 aufweist, zwischen der und der Rückwand 11 des Kunststoffgehäuses 1 eine Druckfeder 12 in Form einer Blattfeder abgestützt ist. Diese Druckfeder 12 hat die Tendenz, den Klingenblock 5 nach vorne in Richtung Führungsleiste 13 des Kunststoffgehäuses 1 zu drücken, wie dies beispielsweise in Fig. 6 dargestellt ist. Die Druckfeder 12 in Form der Blattfeder ist mehrfach gewölbt, wie in Fig. 2 zu erkennen ist, d.h. es reihen sich drei Wölbungen hintereinander an, so daß die Druckfeder 12 mit zwei Knickpunkten an der Rückwand 11 des Kunststoffgehäuses 1 und mit drei Wölbungspunkten an der Leiste 10 des Klingenblocks 5 anliegt.The sectional views in FIGS. 6 and 7 show that the blade block 5 has a strip 10 on the underside, between the and the rear wall 11 of the plastic housing 1, a compression spring 12 in the form of a leaf spring is supported. This compression spring 12 has the tendency to press the blade block 5 forward in the direction of the guide bar 13 of the plastic housing 1, as is shown, for example, in FIG. 6. The compression spring 12 in the form of the leaf spring is curved several times, as can be seen in Fig. 2, ie there are three arches in a row, so that the compression spring 12 with two break points on the rear wall 11 of the plastic housing 1 and with three bulge points on the Bar 10 of the blade block 5 rests.

Weiterhin ist in Fig. 2 zu erkennen, daß der Klingenblock 5 seitlich jeweils einen Nocken 14 aufweist, die an den entsprechenden Führungsschienen 8 angeformt sind. Diese Nocken 14 des Klingenblocks 5 sind durch Öffnungen 15 in den Seitenwänden des Kunststoffgehäuses 1 herausgeführt und damit betätigbar. Diese Öffnungen 15 in den Seitenwänden des Kunststoffgehäuses 1 sind durch seitliche Ausnehmungen sowohl im Oberteil 3 als auch im Unterteil 2 dieses Kunststoffgehäuses 1 nach dem Zusammensetzen dieser beiden Teile definiert.Furthermore, it can be seen in FIG. 2 that the blade block 5 has a cam 14 on each side, which is formed on the corresponding guide rails 8. These cams 14 of the blade block 5 are led out through openings 15 in the side walls of the plastic housing 1 and can thus be actuated. These openings 15 in the side walls of the plastic housing 1 are defined by lateral recesses both in the upper part 3 and in the lower part 2 of this plastic housing 1 after the assembly of these two parts.

Die Rasierklingeneinheit funktioniert wie folgt:
In Fig. 1 und in Fig. 6 ist die Grundstellung der Rasierklingeneinheit und dabei insbesondere des Klingenblocks 5 dargestellt, d.h. der Klingenblock 5 befindet sich in seiner vordersten Position, bei der die Schneidkanten der Rasierklingen 6 auf der Tangente zwischen der vorderen Führungsleiste 13 und der hinteren Abdeckkappe 7 liegen. Bei einer Druckbeaufschlagung in der Mitte des Klingenblocks 5, wie sie in Fig. 3 und in Fig. 7 jeweils durch den Pfeil P angedeutet ist, bewegt sich der Klingenblock 5 zusammen mit den fest daran angeordneten Rasierklingen 6 in Richtung Rückwand 11 des Kunststoffgehäuses 1. Es handelt sich dabei um eine reine Linearbewegung des Klingenblocks 5, so daß dieser gleichmäßig in das Kunststoffgehäuse 1 eintaucht.
The razor blade unit works as follows:
In Fig. 1 and in Fig. 6, the basic position of the razor blade unit and in particular the blade block 5 is shown, ie the blade block 5 is in its foremost position, in which the cutting edges of the razor blades 6 on the tangent between the front guide bar 13 and rear cap 7 are. When pressure is applied in the middle of the blade block 5, as is indicated by the arrow P in FIG. 3 and in FIG. 7, the blade block 5 moves together with those fixedly arranged thereon Razor blades 6 in the direction of the rear wall 11 of the plastic housing 1. This is a pure linear movement of the blade block 5, so that it dips evenly into the plastic housing 1.

Alternativ kann die Druckbeaufschlagung aber auch auf der linken Seite (Fig. 4) oder auf der rechten Seite (Fig. 5) des Klinenblocks 5 erfolgen. Dadurch wird der Klingenblock 5 nicht gleichmäßig über seine gesamte Länge in Richtung Rückwand 11 des Kunststoffgehäuses 1 bewegt, sondern nur in dem Bereich, wo die Druckbeaufschlagung erfolgt, also entweder links (Fig. 4) oder rechts (Fig. 5). Der Klingenblock 5 führt dabei gewissermaßen eine Verschwenkbewegung in der Ebene der Rasierklingen 6 um das gegenüberliegende Ende als Drehpunkt aus.Alternatively, the pressure can also be applied on the left side (FIG. 4) or on the right side (FIG. 5) of the clinic block 5. As a result, the blade block 5 is not moved uniformly over its entire length in the direction of the rear wall 11 of the plastic housing 1, but only in the area where the pressure is applied, that is to say either on the left (FIG. 4) or on the right (FIG. 5). The blade block 5 executes, as it were, a pivoting movement in the plane of the razor blades 6 around the opposite end as a fulcrum.

Mittels der seitlichen Nocken 14 kann der Klingenblock 5 von Hand innerhalb des Kunststoffgehäuses 1 verschoben werden, so daß dadurch eine verbesserte Reinigung der Rasierklingen 6 möglich ist.The blade block 5 can be moved by hand within the plastic housing 1 by means of the lateral cams 14, so that an improved cleaning of the razor blades 6 is possible.
