Description

Langhaarschneideinrichtung für TrockenrasierapparateLong hair cutter for dry shavers
Die Erfindung bezieht sich auf eine Langhaarschneideinrichtung für Trockenrasierapparate mit einem feststehenden, auf einer Rückseite mit einem abgebogenen Flansch versehenen Scherkamm, einer längs diesem geradlinig hin und her verschiebbaren, mittels Federn gegen ihn gedrückten gezahnten Scherklinge und einem am Flansch befe¬ stigten, das Widerlager für die Federn bildenden Federträger.The invention relates to a long-hair cutting device for dry shavers with a fixed shaving comb provided on the back with a bent flange, a toothed shaving blade that can be moved back and forth along this straight line and pressed against it by springs, and a abutment for the abutment for the spring supports forming the springs.
Langhaarschneideinrichtungen dieser Art, die beispielsweise aus der DE-PS 2019978 bekannt sind, haben im Laufe der Entwicklung hinsichtlich ihrer Funktion einen hohen technischen Stand er¬ reicht. Unter dem Gesichtspunkt einer Massenfertigung haben sich jedoch noch Mängel herausgestellt, die geeignet sind, die Ferti¬ gungskosten unnötig in die Höhe zu treiben, aber auch die Funktion der Langhaarschneideinrichtung zu beeinträchtigen. So bedingt die Einrichtung nach der obengenannten Literaturstelle eine Stapel- Montage, bei der die einzelnen Bauelemente nacheinander gleichsam eingefädelt werden müssen. Diese Art der Montage ist zeitraubend und steht einer Automatisierung der Montage, wie sie heute aus Kostengründen angestrebt wird, hindernd entgegen. Der Erfindung liegt daher die Aufgabe zugrunde, eine Langhaarschneideinrichtung der gattungsgemäßen Art zu schaffen, die bei hohem Leistungstan¬ dard mit wenigen Schritten der Vor- und Endmontage auskommt und so die Wirtschaftlichkeit der Herstellung ohne Beeinträchtigung der Funktion weiter verbessert.Long hair cutting devices of this type, which are known for example from DE-PS 2019978, have reached a high technical standard in the course of development in terms of their function. From the point of view of mass production, however, shortcomings have emerged which are suitable for driving up the production costs unnecessarily, but also for impairing the function of the long-hair trimmer. Thus, the device according to the above-mentioned literature requires stack assembly, in which the individual components have to be threaded one after the other. This type of assembly is time-consuming and hinders automation of assembly, as is sought today for cost reasons. The invention is therefore based on the object of providing a long hair cutting device of the generic type which, with a high performance standard, requires only a few steps of pre-assembly and final assembly and thus further improves the economy of manufacture without impairing its function.
Die Erfindung erreicht dies, ausgehend von einer bekannten, spe¬ ziellen Ausbildung der Scherklinge, die sich als besonders vor¬ teilhaft erwiesen hat (vgl. DE-PS 3303989), durch die im Kenn¬ zeichen des Anspruchs 1 angegebenen Mitteln. Die Vormontage be¬ schränkt sich bei der erfindungsgemäßen Langhaarschneideinrichtung auf das Einsetzen der Federn in den Federträger und die Endmontage auf das Einlegen der Scherklinge in den Winkel des Scherkammes mit anschließendem Einknöpfen des Federträgers am Flansch des Scher¬ kammes. Mit diesem Einknöpfen wird die Scherklinge sofort in ihre Arbeitslage- gebrächt, die Zähne von Kamm und Klinge gegeneinander gedrückt und alle Bewegungsmöglichkeiten außer der Arbeitsbewegung beschränkt, ohne daß fertigungsbedingte Eigenheiten von Bauteilen außerhalb der Baueinheit "Langhaarschneideinrichtungen" nachteili¬ gen Einfluß nehmen können, z. B. Toleranzen von Gehäuseteilen. Die Möglichkeiten der automatischen Montage sind offensichtlich.The invention achieves this, starting from a known, special design of the shear blade, which has proven to be particularly advantageous (see DE-PS 3303989), by the means specified in the characterizing part of claim 1. The pre-assembly is limited in the long hair cutting device according to the invention on the insertion of the springs in the spring support and the final assembly on the insertion of the shear blade in the angle of the shear comb with subsequent buttoning of the spring support on the flange of the shear comb. With this buttoning, the shear blade is immediately brought into its working position, the teeth of the comb and the blade are pressed against each other and all movement possibilities are restricted except for the working movement, without manufacturing-related peculiarities of components outside the unit "long-hair cutting devices" being able to have an adverse influence, eg. B. Tolerances of housing parts. The possibilities of automatic assembly are obvious.
Aus der Literatur (DE-PS 2836959, US-PS 4118863) ist zwar die Verwendung eines Hebels oder dergleichen zum Übertragen der Feder¬ kraft in den Bereich nahe der Zähne der Scherklinge grundsätzlich bekannt, jedoch .nicht bei Langhaarschneideinrichtungen der gat¬ tungsgemäßen Art und mit anderer spezieller Ausbildung; dieser Ge¬ danke allein: st daher nicht geeignet, die Aufgabe der Erfindung zu lösen.From the literature (DE-PS 2836959, US-PS 4118863) the use of a lever or the like for transmitting the spring force in the area near the teeth of the shear blade is known in principle, but not with long hair cutting devices of the generic type and with other special education; this idea alone is therefore unsuitable for achieving the object of the invention.
Vorteilhaft sind die Federträger mit den zugehörigen Winkelhebeln einstückig aus Kunststoff ausgeformt und das Gelenk zwischen bei¬ den Bauteilen als Filmscharnier ausgebildet. Der Federträger fällt somit schon bei der Fertigung als ein einziges Bauteil an und braucht nicht in einem gesonderten Montagegang zusammengesetzt zu werden, wie dies z. B. bei der Vorrichtung nach der US-PS 41 18863 der Fall ist.The spring supports with the associated angle levers are advantageously formed in one piece from plastic and the joint between the two components is designed as a film hinge. The spring support is thus incurred during manufacture as a single component and does not need to be assembled in a separate assembly process, as is the case, for. B. in the device according to US-PS 41 18863 the case.
Die Ansprüche 6 und 7 kennzeichnen die vorteilhafte Ausbildung der rückwärtigen Anlage der Scherklinge an zwei Stellen, nämlich am Flanscfi des Scherkammes und am Federträger derart, daß sie nur auf Bauelemente der Langhaarschneideinrichtung und nicht auf außerhalb befindliche Bauteile, z. B. Gehäuseschalen, bezogen sind. Die weiteren Unteransprüche kennzeichnen vorteilhafte und zweck¬ mäßige Ausbildungsformen der Erfindung, die zur Lösung der ge¬ stellten Aufgabe beitragen.The claims 6 and 7 characterize the advantageous design of the rear system of the shear blade in two places, namely on the flanscfi of the shear comb and on the spring support such that they only on components of the long hair cutting device and not on external components, for. B. housing shells are related. The further subclaims characterize advantageous and expedient forms of embodiment of the invention which contribute to the achievement of the object.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung darge¬ stellt.An exemplary embodiment of the invention is shown in the drawing.
Es zeigt:It shows:
Fig. 1 die Ansicht einer Langhaarschneideinrichtung für Trocken¬ rasierapparate von der Vorderseite - rechte Bildhälfte - und von der Rückseite - linke Bildhälfte - und1 shows the view of a long hair cutting device for dry shavers from the front - right half of the image - and from the rear - left half of the image - and
Fig. 2 eine Ansicht längs der Schnittlinien 2-2 in Fig. 1.FIG. 2 is a view along section lines 2-2 in FIG. 1.
Die in der Zeichnung dargestellte Langhaarschneideinrichtung ist, wie Fig. 1 zeigt, grundsätzlich symmetrisch zur Mittellinie A auf¬ gebaut und besteht aus einem Scherkamm 1, der zu seiner Verstei¬ fung hinter dem Bereich seiner Zähne 2 zunächst im stumpfen Winkel nach oben und anschließend zu einem Flansch 3 rechtwinklig - bezo¬ gen auf die Scherebene dere Zähne 2 - nach unten gebogen ist, und aus einer Scherklinge 4, die ein dünnes Klingenblatt 5 aufweist, das auf einem Tragkörper 6 fest montiert ist und mit diesem eine biegesteife Baueinheit bildet. Das Klingenblatt 5 ist in seinem vorderen Bereich mit Zähnen 7 versehen, die mit den Zähnen 2 des Scherkammes 1 zusammenwirken, und auf der Rückseite mit Lappen 8, die durch einen Ausschnitt 9 im Flansch 3 hindurchragend, einer¬ seits auf einem Ansatz 10 des Tragkörpers 6 aufliegen und sich andererseits gegen eine Nase 11 an der Oberkante des Ausschnit¬ tes 9 im Flansch 3 abstützen. Die Scherklinge 4, die mit ihrem rückwärtigen Rand in den Abschnitten neben den Lappen 8 und An¬ sätzen 10 mit Spiel an der Innenfläche des Flansches 3 anliegt, ist somit in ihrem vorderen und hinteren Bereich in der Scherebene am Scherkamm 1 gleitbar geführt und gegen eine Verschiebung sowohl nach innen quer zu ihrer Arbeitsbewegung als auch senkrecht dazu gesichert.The long-hair cutting device shown in the drawing, as shown in FIG. 1, is basically constructed symmetrically to the center line A and consists of a shaving comb 1, which for its stiffening behind the area of its teeth 2 is initially at an obtuse angle upwards and then closed a flange 3 at right angles - with respect to the shear plane of its teeth 2 - is bent downward, and from a shear blade 4 which has a thin blade blade 5 which is fixedly mounted on a support body 6 and forms a rigid unit with it. The blade blade 5 is provided in its front area with teeth 7, which interact with the teeth 2 of the shaving comb 1, and on the back with tabs 8, which protrude through a cutout 9 in the flange 3, on the one hand on a shoulder 10 of the supporting body 6 rest and, on the other hand, are supported against a nose 11 on the upper edge of the cutout 9 in the flange 3. The shear blade 4, which rests with play on the inner surface of the flange 3 with its rear edge in the sections next to the tabs 8 and lugs 10, is thus slidably guided in its front and rear area in the shear plane on the shear ridge 1 and secured against displacement both inwards transversely to its working movement and perpendicularly to it.
Wie Fig. 1 zu entnehmen ist, besitzt der Tragkörper 6 der Scher¬ klinge 4 symmetrisch zur Mittellinie A eine Tasche 12, in die der Kopf eines nicht näher dargestellten Antriebhebels in üblicher Weise eingreift; um seine Bewegungsfreiheit zu gewährleisten, ist im Flansch 3 ein entsprechender Ausschnitt 13 angebracht.As can be seen in FIG. 1, the supporting body 6 of the shear blade 4 has a pocket 12 symmetrical to the center line A, in which the head of a drive lever (not shown in more detail) engages in the usual way; In order to ensure its freedom of movement, a corresponding cutout 13 is made in the flange 3.
Zum Andrücken der Scherklinge 4 gegen den Scherkamm 1 sind Fe¬ dern 14 vorgesehen - die Federachsen sind mit a bezeichnet -, die, paarweise zusammengefaßt, beiderseits der Symmetrielinie-Mittel¬ linie A in besonderen Federträgern 15 untergebracht und mittels angeformter Lappen 16 und Widerlager 17 käfigartig gehalten sind. An den Federträgern 15 sind auf der Rückseite Knöpfe 18 angeformt, die durch eine entsprechend bemessenen schmaleren Bereich 19 des Flansch-Ausschnittes 9 hindurchgreifen, an ihm einrasten und den Federträger 15 am Flansch 3 form- und kraftschl ssig verrasten.To press the shear blade 4 against the shear comb 1, springs 14 are provided - the spring axes are denoted by a - which, combined in pairs, are accommodated on both sides of the center line of symmetry A in special spring supports 15 and by means of molded tabs 16 and abutments 17 are held like a cage. On the spring supports 15 buttons 18 are formed on the back, which reach through a correspondingly dimensioned narrower area 19 of the flange cutout 9, snap into place and lock the spring support 15 on the flange 3 in a positive and non-positive manner.
Entgegengesetzt zu den Federwiderlagern 17 sind am Federträger 15 zwei Winkelhebel 20 vorgesehen, die jeder mit einem Schenkel 21 über ein am Federträger 15 angeformtes Filmscharnier 22 schwenkbar angelenkt sind und mit ihrem freien Schenkel 28 gegen den Tragkör¬ per 6 im Bereich der Zähne 7 des Klingenblattes 5 anliegen bzw. gegen ihn drücken.In contrast to the spring abutments 17, two angle levers 20 are provided on the spring support 15, each of which is pivotably articulated with a leg 21 via a film hinge 22 formed on the spring support 15 and with its free leg 28 against the support body 6 in the region of the teeth 7 of the blade blade 5 or press against it.
Die jedem -Winkelhebe! 20 zugeordnete Feder 14 bewirkt eine Schwenkbewegung des Winkelhebeis im Uhrzeigersinn (Fig. 2), so daß der Federdruck als Anpreßdruck der Zähne 7 der Scherklinge 4 gegen die Zähne 2 des Scherkammes 1 übersetzt wird. Beide Winkelhebel 20 eines Federträgers 15 sind durch einen elastischen Steg 24 mitein¬ ander verbunden. An jedem Federträger 15 ist auf seiner dem Flansch 3 zugewandten Seite eine Stütze 25 angeformt, die in glei¬ cher Richtung und parallel zu den freien Schenkeln 23 der Winkel- hebel 20 zwischen diesen nach oben (Fig. 2) ragt und so bemessen ist, daß ihre rückwärtige, durch den Ausschnitt 9 im Flansch 3 ra¬ gende Fläche 26 an der Innenfläche 27 eines rechtwinklig nach un¬ ten (Fig. 2) abgebogenen Zapfens 28 des Ansatzes 10 am Tragkör¬ per 6 der Scherklinge 4 anliegt. Die Scherklinge 4 ist somit über ihren Tragkörper 6 am Federträger 15 gegen Verschieben quer zu ih¬ rer Arbeitsbewegung auch in Richtung der Zähne 7 gesichert.Every angle lift! 20 associated spring 14 causes a pivoting movement of the Winkelbebeis clockwise (Fig. 2), so that the spring pressure is translated as the contact pressure of the teeth 7 of the shear blade 4 against the teeth 2 of the shear comb 1. Both angle levers 20 of a spring support 15 are connected to one another by an elastic web 24. On each spring support 15, a support 25 is formed on its side facing the flange 3, which in the same direction and parallel to the free legs 23 of the angle lever 20 projects upwards between them (FIG. 2) and is dimensioned in this way, that its rear surface 26, which projects through the cutout 9 in the flange 3, rests on the inner surface 27 of a pin 28 of the extension 10 bent at right angles to the bottom (FIG. 2) on the supporting body 6 of the shear blade 4. The shear blade 4 is thus secured via its support body 6 on the spring support 15 against displacement transversely to its working movement also in the direction of the teeth 7.
Die Langhaarschneideinrichtung ist eine in sich geschlossene funk¬ tionsfähige Einheit, die sehr schmal ausgebildet und in vormon¬ tiertem Zustand vorgeprüft werden kann. Aufgrund ihres geringen Raumbedarfs läßt sie sich nicht nur fest im Gehäuse eines Trocken¬ rasierapparates einbauen, sondern auch bei einer verschiebbaren Einrichtung mit zwei flachen Gehäuseschalen 29 und 30 (Fig. 2) vorteilhaft verwerten. The long-hair cutting device is a self-contained, functional unit that can be made very narrow and can be pre-checked in the pre-assembled state. Because of its small space requirement, it can not only be permanently installed in the housing of a dry shaving apparatus, but can also be advantageously used in the case of a displaceable device with two flat housing shells 29 and 30 (FIG. 2).
