Definitions
- the invention relates to a razor blade unit for a wet shaving apparatus, in which a single razor blade or two parallel razor blades are embedded in a plastic body, the cutting edges of which are partially provided with a cover.
- razor blade units for wet shavers of the type specified at the outset in which a single razor blade or a double razor blade is embedded in a plastic body, the cutting edges of the two razor blades being offset from one another in the double razor blade. So that bumps in the skin cannot be detected by the razor blades during the shaving process and thus cannot be the cause of skin injuries (skin irritations) that are sometimes not visible, it has already been proposed in such razor blade units that the cutting edge of the razor blade is cut into a thin sheet with a cutting edge to divide non-cutting segments.
- a so-called revolver head wet shaver is known, in which several razor blades are arranged uniformly over the circumference on a common blade carrier which can be rotated about an axis by means of a rotary knob and forms a razor head.
- the cutting edges of the razor blades run parallel to this axis of rotation.
- the blade carrier can be rotated by means of the rotary knob in such a way that its razor blades are successively in the shaving position.
- the known blade carrier, together with the razor blades is helically wrapped with wire.
- a disadvantage of this turret wet shaving apparatus is first of all that the turns of the protective wire run obliquely with respect to the vertical of the cutting edges of the razor blades, which defines the shaving direction. This disadvantageously creates a cross component either on the protective wire or on the entire blade carrier, which impairs the shaving properties of the razor. This has a second disadvantage. So that the turns do not run too obliquely, very narrow turns with small distances between the wires must be provided. However, this significantly reduces the effective shaving area, so that the shaving process must be repeated in order to obtain a good shaving result.
- a razor blade unit of the initially specified type of the invention has the object to provide a razor blade unit for a wet razor having an improved cover for the cutting edges of the razor blade.
- the plastic body together old the razor blades is wrapped with a wire with several helical turns lying next to each other and the wire is at least partially guided in grooves formed in the plastic body, the individual turns in the area of the front pressure surface of the razor blade unit to the skin parallel to the shaving direction and at a distance from each other, while they run obliquely in the area of the back.
- a razor blade unit for a wet shaver designed according to this technical teaching has a cover in the form of a protective wire which is considerably improved compared to the prior art and which considerably improves the shaving properties.
- a major advantage is that the wire windings run exactly parallel to the shaving direction in the area of the front pressure surface, without any cross-components, be it on the protective wire or on the razor blade unit as such. This protective wire guide in the area of the front pressure surface thus ensures an optimal shaving process.
- the turns of the protective wire in the front area parallel to the shaving direction and in the rear area obliquely, and due to the guide grooves of the protective wire without slipping in its predetermined positions, a large distance between the turns is made possible, so that overall the razor blade unit according to the invention only a few turns are needed to improve the shaving properties on the one hand and to provide effective protection against unintentional cutting on the other.
- the particular advantage of the few turns is that the effective shaving area is only insignificantly reduced, so that nothing changes in the number of shaving operations during a shave compared to razor blade units without a protective wire.
- the protective wire prevents the formation of a skin fold, so that skin injuries are avoided even in the invisible area.
- the protective wire reduces the required shaving resistance because it also reduces the frictional force that occurs in the protective cap of the razor blade unit to approximately 50% of the total frictional force.
- the wire is preferably made of metal, since metal with skin has a relatively low coefficient of friction, so that the required shaving resistance is reduced to a minimum.
- the wire has a diameter of less than 0.1 mm, so that the effective shaving surface is only minimally reduced.
- the razor blade unit for a wet shaver which can be attached to a handle, not shown, consists of a plastic body 1, in which two razor blades 2,2 'are embedded, the cutting edges 3,3' of which run parallel and offset to one another.
- the plastic body 1 is wrapped together with the razor blades 2,2 'by means of a wire 4.
- This wire 4 forms helical windings which run at a distance from one another, as can be seen in FIGS. 1 and 2.
- the turns of the wire 4 run parallel to the shaving direction, while on the one in FIG. 2 shown back of the razor blade unit, the turns run obliquely.
- the wire 4 is made of metal and preferably has a diameter of less than 0.1 mm. In order to prevent the turns of the wire 4 from shifting laterally on the plastic body 1, the latter is at least partially provided with grooves 5 in which the individual turns of the wire are guided.

Abstract
Description
Die Erfindung betrifft eine Rasierklingeneinheit für einen Naßrasierapparat, bei der in einem Kunststoffkörper eine einzige Rasierklinge bzw. zwei zueinander parallele Rasierklingen eingebettet sind, deren Schneidkanten teilweise mit einer Abdeckung versehen sind.The invention relates to a razor blade unit for a wet shaving apparatus, in which a single razor blade or two parallel razor blades are embedded in a plastic body, the cutting edges of which are partially provided with a cover.
Es sind Rasierklingeneinheiten für Naßrasierapparate der eingangs angegebenen Art bekannt, bei denen in einem Kunststoffkörper eine Einfachrasierklinge oder eine Doppelrasierklinge eingebettet ist, wobei bei der Doppelrasierklinge die Schneidkanten der beiden Rasierklingen versetzt zueinander angeordnet sind. Damit während des Rasiervorganges Unebenheiten der Haut von den Rasierklingen nicht erfaßt werden können und damit nicht die Ursache von manchmal auch nicht sichtbaren Hautverletzungen (Hautirritationen) sein können, ist bei derartigen Rasierklingeneinheiten bereits vorgeschlagen worden, die Schneidkante der Rasierklinge mit einem dünnen Blech in schneidende und nichtschneidende Segmente zu unterteilen.There are razor blade units for wet shavers of the type specified at the outset, in which a single razor blade or a double razor blade is embedded in a plastic body, the cutting edges of the two razor blades being offset from one another in the double razor blade. So that bumps in the skin cannot be detected by the razor blades during the shaving process and thus cannot be the cause of skin injuries (skin irritations) that are sometimes not visible, it has already been proposed in such razor blade units that the cutting edge of the razor blade is cut into a thin sheet with a cutting edge to divide non-cutting segments.
Für moderne Rasierklingeneinheiten und für ein optimales Rasieren ist jedoch eine derartige Abdeckung nicht geeignet, da damit eine starke Reduzierung der wirksamen Schnittfläche verbunden ist. Darüber hinaus bietet diese Art von Abdeckung keinen Schutz gegen eine bei dem Rasiervorgang sich zwangsläufig ergebende Hautfalte, so daß es zu Hautverletzungen kommen kann. Weiterhin wird der Rasierwiderstand erhöht, was mit einer weiteren Reizung der Haut verbunden ist. Schließlich ist diese Abdeckung teuer und aufwendig in der Montage.However, such a cover is not suitable for modern razor blade units and for optimal shaving, since it is associated with a strong reduction in the effective cutting area is. In addition, this type of cover does not provide protection against a skin fold that is inevitable during the shaving process, so that skin injuries can occur. Furthermore, the shaving resistance is increased, which is associated with a further irritation of the skin. After all, this cover is expensive and complex to assemble.
Aus der DE-U-87 00 107 ist ein sogenannter Revolverkopf-Naßrasierapparat bekannt, bei dem mehrere Rasierklingen an einem gemeinsamen, um eine Achse mittels eines Drehknopfes drehbaren sowie einen Rasierkopf bildenden Klingenträger gleichmäßig über den Umfang angeordnet sind. Die Schneidkanten der Rasierklingen verlaufen dabei parallel zu dieser Drehachse. Mittels des Drehknopfes kann der Klingenträger derart gedreht werden, daß sich dessen Rasierklingen nacheinander in der Rasierposition befinden. Um einen Schutz vor Verletzungen bei einem unbeabsichtigten Berühren der Schneidkante der Rasierklingen zu schaffen, ist der bekannte Klingenträger zusammen mit den Rasierklingen mit Draht wendelförmig umwickelt.From DE-U-87 00 107 a so-called revolver head wet shaver is known, in which several razor blades are arranged uniformly over the circumference on a common blade carrier which can be rotated about an axis by means of a rotary knob and forms a razor head. The cutting edges of the razor blades run parallel to this axis of rotation. The blade carrier can be rotated by means of the rotary knob in such a way that its razor blades are successively in the shaving position. In order to provide protection against injuries when the cutting edge of the razor blades is inadvertently touched, the known blade carrier, together with the razor blades, is helically wrapped with wire.
Nachteilig bei diesem Revolverkopf-Naßrasierapparat ist zunächst, daß die Windungen des Schutzdrahtes bezüglich zur Senkrechten der Schneidkanten der Rasierklingen, welche die Rasierrichtung definiert, schräg verlaufen. Dies erzeugt in nachteiliger Weise eine Querkomponente entweder auf den Schutzdraht oder aber auf den gesamten Klingenträger, welche die Rasiereigenschaften des Rasierapparates beeinträchtigt. Damit verbunden ist ein zweiter Nachteil. Damit nämlich die Windungen nicht zu sehr schräg verlaufen, müssen sehr enge Windungen mit geringen Abständen zwischen den Drähten vorgesehen werden. Dadurch wird aber die wirksame Rasierfläche erheblich vermindert, so daß der Rasiervorgang wiederholt werden muß, um ein gutes Rasierergebnis zu erhalten.A disadvantage of this turret wet shaving apparatus is first of all that the turns of the protective wire run obliquely with respect to the vertical of the cutting edges of the razor blades, which defines the shaving direction. This disadvantageously creates a cross component either on the protective wire or on the entire blade carrier, which impairs the shaving properties of the razor. This has a second disadvantage. So that the turns do not run too obliquely, very narrow turns with small distances between the wires must be provided. However, this significantly reduces the effective shaving area, so that the shaving process must be repeated in order to obtain a good shaving result.
Ausgehend von einer Rasierklingeneinheit der eingangs angegebenen Art liegt der Erfindung die Aufgabe zugrunde, eine Rasierklingeneinheit für einen Naßrasierapparat mit einer verbesserten Abdeckung für die Schneidkanten der Rasierklinge zu schaffen.Starting from a razor blade unit of the initially specified type of the invention has the object to provide a razor blade unit for a wet razor having an improved cover for the cutting edges of the razor blade.
Als technische Lösung wird mit der Erfindung vorgeschlagen, daß der Kunststoffkörper zusammen alt den Rasierklingen mit einem Draht mit mehreren nebeneinanderliegenden, wendelförmigen Windungen umwickelt ist und dabei der Draht zumindest teilweise in im Kunststoffkörper ausgebildeten Rillen geführt ist, wobei die einzelnen Windungen im Bereich der vorderen Andrückfläche der Rasierklingeneinheit an die Haut parallel zur Rasierrichtung und mit Abstand zueinander verlaufen, während sie im Bereich der Rückseite schräg verlaufen.As a technical solution it is proposed with the invention that the plastic body together old the razor blades is wrapped with a wire with several helical turns lying next to each other and the wire is at least partially guided in grooves formed in the plastic body, the individual turns in the area of the front pressure surface of the razor blade unit to the skin parallel to the shaving direction and at a distance from each other, while they run obliquely in the area of the back.
Eine nach dieser technischen Lehre ausgebildete Rasierklingeneinheit für einen Naßrasierapparat weist eine im Vergleich zum Stand der Technik erheblich verbesserte Abdeckung in Form eines Schutzdrahtes auf, welcher die Rasiereigenschaften beträchtlich verbessert. Ein wesentlicher Vorteil dabei ist, daß im Bereich der vorderen Andrückfläche die Drahtwindungen exakt parallel zur Rasierrichtung verlaufen, ohne daß irgendwelche Querkomponenten, sei es auf den Schutzdraht, sei es auf die Rasierklingeneinheit als solche auftreten. Es wird somit durch diese Schutzdrahtführung im Bereich der vorderen Andrückfläche ein optimaler Rasierablauf erzielt. Darüber hinaus wird aufgrund der Tatsache, daß die Windungen des Schutzdrahtes im vorderen Bereich parallel zur Rasierrichtung und im hinteren Bereich schräg verlaufen, wobei aufgrund der Führungsrillen der Schutzdraht ohne zu verrutschen in seinen vorgegebenen Positionen verläuft, ein großer Abstand zwischen den Windungen ermöglicht, so daß insgesamt die erfindungsgemäße Rasierklingeneinheit nur wenige Windungen benötigt, um einerseits die Rasiereigenschaften zu verbessern und um andererseits einen wirksamen Schutz gegen unbeabsichtigtes Schneiden zu liefern. Der besondere Vorteil der wenigen Windungen ist dabei, daß die wirksame Rasierfläche nur unbeträchtlich verringert wird, so daß sich an der Anzahl der Rasiervorgänge während einer Rasur im Vergleich zu Rasierklingeneinheiten ohne Schutzdraht nichts ändert. Darüber hinaus verhindert der Schutzdraht die Bildung einer Hautfalte, so daß Hautverletzungen auch im nicht sichtbaren Bereich vermieden werden. Darüber hinaus reduziert der Schutzdraht den erforderlichen Rasierwiderstand, da er auch die Reibungskraft, die in der Schutzkappe der Rasierklingeneinheit zu ca. 50 % der Gesamtreibungskraft auftritt, reduziert.A razor blade unit for a wet shaver designed according to this technical teaching has a cover in the form of a protective wire which is considerably improved compared to the prior art and which considerably improves the shaving properties. A major advantage is that the wire windings run exactly parallel to the shaving direction in the area of the front pressure surface, without any cross-components, be it on the protective wire or on the razor blade unit as such. This protective wire guide in the area of the front pressure surface thus ensures an optimal shaving process. In addition, due to the fact that the turns of the protective wire in the front area parallel to the shaving direction and in the rear area obliquely, and due to the guide grooves of the protective wire without slipping in its predetermined positions, a large distance between the turns is made possible, so that overall the razor blade unit according to the invention only a few turns are needed to improve the shaving properties on the one hand and to provide effective protection against unintentional cutting on the other. The particular advantage of the few turns is that the effective shaving area is only insignificantly reduced, so that nothing changes in the number of shaving operations during a shave compared to razor blade units without a protective wire. In addition, the protective wire prevents the formation of a skin fold, so that skin injuries are avoided even in the invisible area. In addition, the protective wire reduces the required shaving resistance because it also reduces the frictional force that occurs in the protective cap of the razor blade unit to approximately 50% of the total frictional force.
Vorzugsweise besteht der Draht aus Metall, da Metall mit Haut einen relativ geringen Reibungskoeffizienten besitzt, so daß der erforderliche Rasierwiderstand auf ein Minimum reduziert wird.The wire is preferably made of metal, since metal with skin has a relatively low coefficient of friction, so that the required shaving resistance is reduced to a minimum.
In einer Weiterbildung des Drahtes weist dieser gemäß einem weiteren Merkmal der Erfindung einen Durchmesser von weniger als 0,1 mm auf, so daß die wirksame Rasierfläche nur minimal reduziert wird.In a further development of the wire, according to a further feature of the invention, it has a diameter of less than 0.1 mm, so that the effective shaving surface is only minimally reduced.
