Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Halterung einer Scherfolie mittels ihrer Schenkelenden im Scherkopfrahmen eines Trockenrasierapparates, wobei die Schenkelenden der Scherfolie federnd ausgebildet und am Scherkopfrahmen lösbar befestigt sind.The invention relates to a device for holding a shaving foil by means of its leg ends in the shaving head frame of a dry shaving apparatus, the leg ends of the shaving foil being resilient and releasably attached to the shaving head frame.

Trockenrasierapparate mit solchen Vorrichtungen sind in verschiedensten Ausführungen bekannt. Der Scherkopf dieser Apparate besitzt im allgemeinen Mittel zur Halterung der ihm zugeordneten Scherfolie, an deren Innenseite bekanntlich ein mehrere Messerblätter umfassender Messerblock entlanggleitet und dabei die durch die Löcher der Scherfolie hindurchtretenden Bartstoppeln abschneidet. Der Messerblock ist mittels einer geeigneten Kupplung mit dem Antrieb des Trockenrasierapparates verbunden und wird durch eine Feder gegen die Scherfolie gedrückt. Zur Halterung der Scherfolie innerhalb des Scherkopfes sind im allgemeinen recht aufwendige Vorrichtungen mit relativ grossem Raumbedarf vorgesehen, die einerseits die Schenkelenden der Scherfolie im Scherkopfinneren festlegen und, falls eine elastische Halterung erwünscht ist, andererseits ein nachgiebiges Gleiten der Scherfolienenden im Bereich ihrer Befestigungsmittel erlauben.Various types of dry shavers with such devices are known. The shaving head of these apparatuses generally has means for holding the shaving foil assigned to it, on the inside of which, as is known, a knife block comprising a plurality of knife blades slides along and cuts off the stubble stubble passing through the holes in the shaving foil. The knife block is connected to the drive of the dry shaving apparatus by means of a suitable coupling and is pressed against the shaving foil by a spring. To hold the shaving foil inside the shaving head, generally quite complex devices with a relatively large space requirement are provided, which on the one hand fix the leg ends of the shaving foil inside the shaving head and, on the other hand, if elastic holding is desired, on the other hand allow the shaving foil ends to slide in the area of their fastening means.

Aus der DE-B-1 069 501 ist ein Scherkopf für einen Trockenrasierapparat bekannt, bestehend aus einer Tragplatte, einem auf der Tragplatte unter Zwischenschaltung von Lagerkugeln gleitend angeordneten Messerblock sowie einer den Messerblock umgebenden Scherfolie, die mittels federnd ausgebildeter, die Tragplatte untergreifender Haken an der Tragplatte lösbar befestigt ist. Die federnden Haken spannen die Scherfolie stramm auf den nicht federnd gelagerten Messerblock auf.From DE-B-1 069 501 a shaving head for a dry shaver is known, consisting of a support plate, a knife block slidably arranged on the support plate with the interposition of bearing balls, and a shaving foil surrounding the knife block, which is attached by means of resilient hooks which engage under the support plate the support plate is releasably attached. The resilient hooks tighten the shaving foil tightly onto the non-resilient knife block.

Aufgabe der Erfindung ist es, die bekannte Vorrichtung zur elastischen Halterung der Scherfolie in einem Scherkopfrahmen derart weiterzubilden, dass eine gute Anlage eines federnd gelagerten Untermessers an der Scherfolieninnenseite gewährleistet ist.The object of the invention is to further develop the known device for the elastic holding of the shaving foil in a shaving head frame in such a way that a good contact of a spring-mounted lower knife on the inside of the shaving foil is ensured.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Nach einer Ausführungsform der Erfindung werden die Führungselemente durch im Scherkopfrahmen vorgesehene längsgeschlitzte, rohrförmige Aufnahmen gebildet. Gemäss einer anderen Ausführungsform werden die Führungselemente aus am Scherkopfrahmen vorgesehene Lagerstangen oder Lagerbolzen gebildet.According to one embodiment of the invention, the guide elements are formed by longitudinally slotted tubular receptacles provided in the shaving head frame. According to another embodiment, the guide elements are formed from bearing rods or bearing bolts provided on the shaving head frame.

Die nach diesen Ausführungsformen gebildete elastische Halterung der Scherfolie im Scherkopfrahmen hat den Vorteil, dass bei Druckbelastung der über einen unter Federdruck stehenden Messerblock gespannten Scherfolie die gerollten Schenkelenden sich spiralförmig enger zusammenrollen und bei Entlastung infolge der ihnen innenwohnenden Federspannkraft wieder in ihre Ausgangsstellung zurückrollen bzw. zurückfedern, so dass stets eine gute Anlage des Messerblockes an der Scherfolieninnenseite gewährleistet ist.The elastic mounting of the shaving foil in the shaving head frame formed according to these embodiments has the advantage that when the shaving foil stretched over a knife block under spring pressure is loaded, the rolled leg ends curl up more tightly in a spiral and roll back or spring back when released due to the spring tension force inherent in them , so that a good contact of the knife block on the inside of the shaving foil is always guaranteed.

Nach der Erfindung können die Schenkelenden gerollter Gestalt der Scherfolie angeformt sein. An die Scherfolie können jedoch auch Schenkel gerollter Gestalt angesetzt sein. Bei der letztgenannten Ausführungsform nach der Erfindung hat man es in der Hand, für diese Scherfolienenden ein geeignetes Material mit optimaler Federungseigenschaft unabhängig vom Material der eigentlichen Scherfolie auszuwählen.According to the invention, the leg ends can be formed in a rolled shape on the shaving foil. However, legs of rolled shape can also be attached to the shaving foil. In the last-mentioned embodiment according to the invention, it is in your hand to select a suitable material with optimal suspension properties for these shaving foil ends, regardless of the material of the actual shaving foil.

Um das Bauvolumen des Scherkopfes in Grenzen zu halten, ein Auswechseln der Scherfolie zu erleichtern und die Reinigung des Scherkopfes in der üblichen Weise zu ermöglichen, sind die rohrförmigen Aufnahmen in den Wandungen eines vom Apparategehäuse abnehmbaren Scherkopfrahmens angebracht.In order to keep the construction volume of the shaving head within limits, to facilitate replacement of the shaving foil and to enable cleaning of the shaving head in the usual way, the tubular receptacles are mounted in the walls of a shaving head frame which can be removed from the apparatus housing.

Nach der Erfindung sind die rohrförmigen Aufnahmen Bestandteil eines die Scherfolie im Scherkopfrahmen festlegenden Riegelgesperres.According to the invention, the tubular receptacles are part of a locking mechanism which fixes the shaving foil in the shaving head frame.

Vorteilhaft dienen hierzu die rohrförmigen Aufnahmen der verschwenkbar angeordneten Hebeln des Riegelgesperres als Gelenkachse.The tubular receptacles of the pivotably arranged levers of the locking mechanism advantageously serve as a hinge axis for this purpose.

Durch diese Anordnung sind den rohrförmigen Aufnahmen des Scherkopfes zwei Funktionen zugeordnet, nämlich zum einen die Funktion der federnden Halterung der Scherfolie und zum anderen die Funktion der Lagerung der schwenkbaren Hebel des die Scherfolie festlegenden Riegelgesperres.With this arrangement, the tubular receptacles of the shaving head are assigned two functions, namely on the one hand the function of the resilient mounting of the shaving foil and on the other hand the function of the mounting of the pivotable levers of the locking mechanism which defines the shaving foil.

Fig. 1 zeigt in einer Prinzipdarstellung die erfindungsgemässe Scherfolienhalterung, die - wie ersichtlich - hier ausserhalb des von der Scherfolie 1 umschlossenen Raumes angeordnet ist. Die freien Enden 1.11 und 1.21 der Schenkel 1.1 und 1.2 der Scherfolie 1 sind nach Art einer Spiralfeder nach aussen gerollt und haben die Wirkung einer Rollfeder, wie sie beispielsweise in Federwerken von Uhren Verwendung finden. Mittige Ausschnitte 1.12 und 1.22 in den Folienschenkeln 1.1 und 1.2 dienen dem Eindringen von Kupplungs- oder Verbindungsmitteln des Scherkopfes, beispielsweise für dessen nicht dargestellten Langhaarschneider. Die gerollten Enden 1.11 und 1.21 der Scherfolie 1 können der Scherfolie angeformt sein, d. h. direkt aus dem Scherfolienmaterial geformt sein, sie können aber auch aus einem anderen Material als die Scherfolie bestehen und an die Scherfolie angesetzt sein, wie in Fig. 1 bei 1.23 angedeutet ist.1 shows a basic illustration of the shaving foil holder according to the invention, which - as can be seen - is arranged here outside the space enclosed by the shaving foil 1. The free ends 1.11 and 1.21 of the legs 1.1 and 1.2 of the shaving foil 1 are rolled outward in the manner of a spiral spring and have the effect of a roller spring, as is used, for example, in clockwork springs. Central cutouts 1.12 and 1.22 in the film legs 1.1 and 1.2 serve for the penetration of coupling or connecting means of the shaving head, for example for its long hair trimmer, not shown. The rolled ends 1.11 and 1.21 of the shear Foil 1 can be molded onto the shaving foil, ie it can be formed directly from the shaving foil material, but it can also consist of a different material than the shaving foil and can be attached to the shaving foil, as indicated at 1.23 in FIG. 1.

Rohrförmige Aufnahmen 2, die, wie Fig. 2 zeigt, dem Scherkopf des Trockenrasierapparates zugeordnet, beispielsweise angeformt sein können, dienen den Schenkelenden 1.11 und 1.21 der Scherfolie 1 als hülsenartiges Gehäuse, das jedes der aufgerollten Schenkelenden mit Spiel aufnimmt. Die Schenkelenden 1.11 und 1.21 können sich sonach innerhalb der Aufnahme 2 spiralartig ausdehnen und zusammenziehen und der Druckbelastung auf die Scherfolie, die durch den Klingen- bzw. Messerblock (Fig. 2) oder den Rasierdruck ausgeübt wird, entgegenwirken. Zum Einführen der Scherfolienschenkel 1.1 und 1.2 in die Aufnahme 2 ist diese mit einem Längsschlitz 2.1 versehen.Tubular receptacles 2, which, as shown in FIG. 2, can be assigned to the shaving head of the dry shaving apparatus, for example formed on them, serve the leg ends 1.11 and 1.21 of the shaving foil 1 as a sleeve-like housing which accommodates each of the rolled-up leg ends with play. The leg ends 1.11 and 1.21 can thus expand and contract spirally within the receptacle 2 and counteract the pressure load on the shaving foil which is exerted by the blade or knife block (FIG. 2) or the shaving pressure. To insert the shaving foil legs 1.1 and 1.2 into the receptacle 2, the latter is provided with a longitudinal slot 2.1.

Fig. 2 zeigt den Scherkopf 3 des Trockenrasierapparates, mit einem auf dem Apparategehäuse 4 abnehmbar angeordneten Scherkopfrahmen 5, in dessen geschlossene Seitenwände 6 und 7 die rohrförmigen Aufnahmen 2 für die Scherfolie 1 eingeformt sind. Mit der Scherfolie 1 wirkt ein Messerkopf 8 zusammen, der in üblicher Weise durch eine Feder 9, hier als Balgenfeder dargestellt, gegen die Scherfolie 1 gedrückt wird. Die Scherfolie 1 ist, wie in Fig. 1 dargestellt, mit ihren gerollten Enden 1.11 und 1.21 in die Aufnahmen 2 eingeführt.Fig. 2 shows the shaving head 3 of the dry shaving apparatus, with a shaving head frame 5 which is removably arranged on the apparatus housing 4 and in the closed side walls 6 and 7 of which the tubular receptacles 2 for the shaving foil 1 are molded. A cutter head 8 interacts with the shaving foil 1 and is pressed against the shaving foil 1 in the usual way by a spring 9, shown here as a bellows spring. As shown in FIG. 1, the shear foil 1 is inserted into the receptacles 2 with its rolled ends 1.11 and 1.21.

Die Fig. 3 bis 5 zeigen die erfindungsgemässe Scherfolienhalterung als Bestandteil eines die Scherfolie 1 am Scherkopf 3 festlegenden Riegelgesperres 10. Auch in diesen Figuren sind die Scherfolie mit 1, ihre freien Schenkel mit 1.1 und 1.2 und ihre spiralförmig gerollten Schenkelenden mit 1.11 und 1.21 bezeichnet. Die diese mit Spiel umhüllenden rohrförmigen Aufnahmen 2 (Fig. 1) des Scherkopfrahmens des Trockenrasierapparates sind hier jedoch der besseren Übersicht wegen mit 2.2 und 2.3 bezeichnet worden.3 to 5 show the shaving foil holder according to the invention as part of a locking mechanism 10 which fixes the shaving foil 1 on the shaving head 3. In these figures, too, the shaving foil is denoted by 1, its free legs by 1.1 and 1.2 and its spirally rolled leg ends by 1.11 and 1.21 . The tubular receptacles 2 (FIG. 1) of the shaving head frame of the dry shaving apparatus, which envelop them with play, have here been designated 2.2 and 2.3 for the sake of clarity.

Wie ersichtlich, durchsetzen die beiden Hebel 10.1 und 10.2 des Riegelgesperres 10 je einen korrespondierenden Ausschnitt des Scherkopfrahmens 5 wobei die Aufnahmen 2 zugleich je eine Gelenkachse des zugehörigen Hebels 10.1 oder 10.2 des Riegelgesperres 10 bilden. Dieses Riegelgesperre umfasst - wie gesagt - zwei um die Gelenkachse 2.2 bzw. 2.3 schwenkbaren doppelarmigen Hebel 10.1 und 10.2, deren oberes Teilstück als Bedienungshandhabe dient und deren unteres Teilstück je eine nach aussen gerichtete Nase 10.3 bzw. 10.4 aufweist.As can be seen, the two levers 10.1 and 10.2 of the locking mechanism 10 each pass through a corresponding section of the shaving head frame 5, the receptacles 2 simultaneously forming an articulated axis of the associated lever 10.1 or 10.2 of the locking mechanism 10. This locking mechanism comprises - as mentioned - two double-armed levers 10.1 and 10.2 which can be pivoted about the articulation axis 2.2 or 2.3, the upper part of which serves as an operating handle and the lower part of which has an outwardly directed nose 10.3 or 10.4.

Ist der Scherkopf 3 auf das Apparategehäuse 4 des Trockenrasierapparates aufgesetzt (Fig. 3), so untergreifen die Nasen 10.3 und 10.4 und Hebel 10.1 und 10.2 die Seitenwände 5.1 und 5.2 des Scherkopfrahmens 5 und legen somit die Scherfolie 1 in vorbestimmter Lage am Scherkopfrahmen 5 fest. In dieser Lage liegen die unteren Enden der Hebel 10.1 und 10.2 innen an einem Dom 4.1 des Apparategehäuses an und können in dieser Position nicht betätigt werden. Ferner liegt der Messerkopf 8, der bekannterweise mit dem im Apparategehäuse 4 vorgesehenen Antrieb des Trokkenrasierapparates verbunden ist und von diesem in hin- und herschwingende Bewegung versetzt wird, unter Einwirkung der ihn beaufschlagenden Druckfeder 9 an der Scherfolie 1 an, so dass der Trockenrasierapparat betriebsbereit ist.If the shaving head 3 is placed on the apparatus housing 4 of the dry shaving apparatus (FIG. 3), the lugs 10.3 and 10.4 and levers 10.1 and 10.2 engage under the side walls 5.1 and 5.2 of the shaving head frame 5 and thus fix the shaving foil 1 in a predetermined position on the shaving head frame 5 . In this position, the lower ends of the levers 10.1 and 10.2 lie against the inside of a dome 4.1 of the apparatus housing and cannot be actuated in this position. Furthermore, the cutter head 8, which is known to be connected to the drive of the dry shaving razor provided in the apparatus housing 4 and is caused to oscillate by it, is in contact with the shaving foil 1 under the action of the compression spring 9, so that the dry shaving razor is ready for operation .

Soll die Scherfolie 1 entnommen werden, beispielsweise zur Reinigung, so wird - wie Fig. 4 zeigt - zunächst der Scherkopf 3 vom Apparatekörper 4 abgehoben und dann werden die beiden doppelarmigen Hebel 10.1 und 10.2 auseinandergespreizt, wodurch die beiden Nasen 10.3 und 10.4 aus dem Bereich der beiden Seitenwänden 5.1 und 5.2 des Scherkopfrahmens 5 herausschwenken und damit die Verriegelung zwischen der Scherfolie 1 und dem Scherkopfrahmen 5 gelöst ist. Das erneute Einsetzen der Scherfolie 1 in den Scherkopfrahmen 5 geschieht unter Spreizen der beiden doppelarmigen Hebel 10.1 und 10.2 in entgegengesetzter Weise.If the shaving foil 1 is to be removed, for example for cleaning, the shaving head 3 is first lifted off the apparatus body 4, as shown in FIG. 4, and then the two double-armed levers 10.1 and 10.2 are spread apart, as a result of which the two lugs 10.3 and 10.4 are removed from the area of the two side walls 5.1 and 5.2 of the shaving head frame 5 swing out and thus the lock between the shaving foil 1 and the shaving head frame 5 is released. The renewed insertion of the shaving foil 1 into the shaving head frame 5 takes place with the two double-armed levers 10.1 and 10.2 spread apart in the opposite manner.

Eine Variante zu dem in den Fig. 3 und 4 dargestellten Riegelgesperre zeigt die Fig. 5. Hier sind die rohrförmigen Aufnahmen 2.2 und 2.3 und die doppelarmigen Hebel 11.1 und 11.2 des Riegelgesperres 11 derart gestaltet und im Scherkopfrahmen 5 angeordnet, dass ihre Nasen 11.3 und 11.4 von aussen die Seitenwände 5.1 und 5.2 des Scherkopfrahmens 5 untergreifen. Diese Anordnung hat den nicht unbedeutenden Vorteil, dass zum Entriegeln der Scherfolie vom Scherkopfrahmen 5 die oberen Teilstücke der beiden Hebel 11.1 und 11.2 in bedienungsfreundlicher Weise lediglich nach innen, also gegeneinander gedrückt zu werden brauchen, um die Nasen 11.3 und 11.4 aus dem Bereich der Seitenwände 5.1 und 5.2 des Scherkopfrahmens auszuschwenken.3 shows a variant of the locking mechanism shown in FIGS. 3 and 4. Here, the tubular receptacles 2.2 and 2.3 and the double-armed levers 11.1 and 11.2 of the locking mechanism 11 are designed and arranged in the shaving head frame 5 such that their lugs 11.3 and 11.4 reach under the side walls 5.1 and 5.2 of the shaving head frame 5 from the outside. This arrangement has the not insignificant advantage that in order to unlock the shaving foil from the shaving head frame 5, the upper sections of the two levers 11.1 and 11.2 need only be pressed inwards, that is to say against one another, in order to remove the lugs 11.3 and 11.4 from the region of the side walls 5.1 and 5.2 of the shaving head frame.

In Fig. 6 ist eine weitere Ausführungsform zur Halterung der Scherfolie im Scherkopfrahmen dargestellt. Die gerollten Schenkelenden 1.11 und 1.21 der Scherfolie 1 umgeben zwei als Führungselemente dienende Lagerstangen 2.4 und 2.5, deren Enden in den Stirnwangen 15 und 16 des Scherkopfrahmens 5 drehbar gelagert oder an diesem befestigt sind. Die gerollten Schenkelenden der Scherfolie 1 federn aufgrund der vorgesehenen Rollfedereigenschaft entsprechend dem auf die Scherfolie 1 einwirkenden Druck bzw. entsprechend der nach einer Druckeinwirkung auftretenden Entlastung um die Lagerstangen 2.4 und 2.5. Anstelle von den dargestellten beiden Lagerstangen 2.4 und 2.5 können auch vier Lagerbolzen an den Stirnwangen des Scherkopfrahmens 5 als Führungselemente vorgesehen werden.6 shows a further embodiment for holding the shaving foil in the shaving head frame. The rolled leg ends 1.11 and 1.21 of the shaving foil 1 surround two bearing rods 2.4 and 2.5, which serve as guide elements, the ends of which are rotatably mounted in or attached to the end cheeks 15 and 16 of the shaving head frame 5. The rolled leg ends of the shaving foil 1 spring due to the envisaged roll spring property in accordance with the pressure acting on the shaving foil 1 or in accordance with the relief occurring after the action of pressure around the bearing rods 2.4 and 2.5. Instead of the two bearing rods 2.4 and 2.5 shown, four bearing bolts can also be provided on the end cheeks of the shaving head frame 5 as guide elements.
