Definitions
- the invention relates to a long-hair cutter for dry shavers with a fixed, provided on a back with a bent flange shaving comb, a straight along this back and forth, by means of springs toothed shaving blade and attached to the flange, the abutment for the springs forming spring support.
- the invention achieves this, starting from a known, special design of the shear blade, which has proven to be particularly advantageous (cf. DE-PS 33 03 989), by the means indicated 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 carrier and the final assembly on the insertion of the shear blade in the angle of the shear comb with subsequent buttoning of the spring carrier on the flange of the shear comb.
- 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 18 863 the case.
- the claims 6 and 7 characterize the advantageous design of the rear system of the shear blade in two places, namely on the flange 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 such.
- B. housing shells are related.
- the long-hair cutting device shown in the drawing is, as shown in FIG. 1, 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, initially at an obtuse angle upwards and then at right angles to a flange 3 - Related to the shear plane teeth 2 - is bent down, and from a shear blade 4, which has a thin blade 5, which is fixedly mounted on a support body 6 and forms a rigid unit with this.
- 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 rest on a shoulder 10 of the support body 6 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 perpendicular to it.
- the support 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 manner; In order to ensure its freedom of movement, a corresponding cutout 13 is made in the flange 3.
- 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 are held in a cage-like manner by means of molded-on tabs 16 and abutments 17.

Abstract
Description
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 befestigten, das Widerlager für die Federn bildenden Federträger.The invention relates to a long-hair cutter for dry shavers with a fixed, provided on a back with a bent flange shaving comb, a straight along this back and forth, by means of springs toothed shaving blade and attached to the flange, the abutment for the springs forming spring support.
Langhaarschneideinrichtungen dieser Art, die beispielsweise aus der DE-PS 20 19 978 bekannt sind, haben im Laufe der Entwicklung hinsichtlich ihrer Funktion einen hohen technischen Stand erreicht. Unter dem Gesichtspunkt einer Massenfertigung haben sich jedoch noch Mängel herausgestellt, die geeignet sind, die Fertigungskosten 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 Leistungstandard 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 20 19 978, have reached a high technical level in the course of development in terms of their function. From the point of view of mass production, however, deficiencies 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 a 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 creating a long-hair cutting device of the generic type which manages with a high performance standard with a few steps of pre-assembly and final assembly and thus further improves the economy of manufacture without impairing the function.
Die Erfindung erreicht dies, ausgehend von einer bekannten, speziellen Ausbildung der Scherklinge, die sich als besonders vorteilhaft erwiesen hat (vgl. DE-PS 33 03 989), durch die im Kennzeichen des Anspruchs 1 angegebenen Mitteln. Die Vormontage beschränkt 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 Scherkammes. Mit diesem Einknöpfen wird die Scherklinge sofort in ihre Arbeitslage gebracht, 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" nachteiligen 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 (cf. DE-PS 33 03 989), by the means indicated 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 carrier and the final assembly on the insertion of the shear blade in the angle of the shear comb with subsequent buttoning of the spring carrier 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 options are restricted except for the working movement, without manufacturing-related peculiarities of components outside the "long-hair cutting devices" unit having a detrimental influence, e.g. B. Tolerances of housing parts. The possibilities of automatic assembly are obvious.
Aus der Literatur (DE-PS 28 36 959, US-PS 4 118 863) ist zwar die Verwendung eines Hebels oder dergleichen zum Übertragen der Federkraft in den Bereich nahe der Zähne der Scherklinge grundsätzlich bekannt, jedoch nicht bei Langhaarschneideinrichtungen der gattungsgemäßen Art und mit anderer spezieller Ausbildung; dieser Gedanke allein ist daher nicht geeignet, die Aufgabe der Erfindung zu lösen.From the literature (DE-PS 28 36 959, US-PS 4 118 863) 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 not suitable for achieving the object of the invention.
Vorteilhaft sind die Federträger mit den zugehörigen Winkelhebeln einstückig aus Kunststoff ausgeformt und das Gelenk zwischen beiden 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 18 863 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 18 863 the case.
Die Ansprüche 6 und 7 kennzeichnen die vorteilhafte Ausbildung der rückwärtigen Anlage der Scherklinge an zwei Stellen, nämlich am Flansch des Scherkammes und am Federträger derart, daß sie nur auf Bauelemente der Langhaarschneideinrichtung und nicht auf außerhalb befindliche Bauteile, z. B. Gehäuseschalen, bezogen sind.The
Die weiteren Unteransprüche kennzeichnen vorteilhafte und zweckmäßige Ausbildungsformen der Erfindung, die zur Lösung der gestellten Aufgabe beitragen.The further sub-claims characterize advantageous and expedient forms of training of the invention, which contribute to the solution of the task.

- a view along the section lines 2-2 in Fig. 1st
Die in der Zeichnung dargestellte Langhaarschneideinrichtung ist, wie Fig. 1 zeigt, grundsätzlich symmetrisch zur Mittellinie A aufgebaut und besteht aus einem Scherkamm 1, der zu seiner Versteifung hinter dem Bereich seiner Zähne 2 zunächst im stumpfen Winkel nach oben und anschließend zu einem Flansch 3 rechtwinklig - bezogen 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, einerseits auf einem Ansatz 10 des Tragkörpers 6 aufliegen und sich andererseits gegen eine Nase 11 an der Oberkante des Ausschnittes 9 im Flansch 3 abstützen. Die Scherklinge 4, die mit ihrem rückwärtigen Rand in den Abschnitten neben den Lappen 8 und Ansätzen 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 is, as shown in FIG. 1, basically constructed symmetrically to the center line A and consists of a shaving comb 1 which, for its stiffening behind the area of its
Wie Fig. 1 zu entnehmen ist, besitzt der Tragkörper 6 der Scherklinge 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
Zum Andrücken der Scherklinge 4 gegen den Scherkamm 1 sind Federn 14 vorgesehen - die Federachsen sind mit a bezeichnet -, die, paarweise zusammengefaßt, beiderseits der Symmetrielinie-Mittellinie 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 kraftschlüssig verrasten.To press the shear blade 4 against the shear comb 1,
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 Tragkörper 6 im Bereich der Zähne 7 des Klingenblattes 5 anliegen bzw. gegen ihn drücken.In contrast to the
Die jedem Winkelhebel 20 zugeordnete Feder 14 bewirkt eine Schwenkbewegung des Winkelhebels 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 miteinander verbunden. An jedem Federträger 15 ist auf seiner dem Flansch 3 zugewandten Seite eine Stütze 25 angeformt, die in gleicher Richtung und parallel zu den freien Schenkeln 23 der Winkelhebel 20 zwischen diesen nach oben (Fig. 2) ragt und so bemessen ist, daß ihre rückwärtige, durch den Ausschnitt 9 im Flansch 3 ragende Fläche 26 an der Innenfläche 27 eines rechtwinklig nach unten (Fig. 2) abgebogenen Zapfens 28 des Ansatzes 10 am Tragkörper 6 der Scherklinge 4 anliegt. Die Scherklinge 4 ist somit über ihren Tragkörper 6 am Federträger 15 gegen Verschieben quer zu ihrer Arbeitsbewegung auch in Richtung der Zähne 7 gesichert.The
Die Langhaarschneideinrichtung ist eine in sich geschlossene funktionsfähige Einheit, die sehr schmal ausgebildet und in vormontiertem Zustand vorgeprüft werden kann. Aufgrund ihres geringen Raumbedarfs läßt sie sich nicht nur fest im Gehäuse eines Trockenrasierapparates einbauen, sondern auch bei einer verschiebbaren Einrichtung mit zwei flachen Gehäuseschalen 29 und 30 (Fig. 2) vorteilhaft verwerten.The long hair trimmer is a self-contained, functional unit that is very narrow and can be pretested in a preassembled state. Because of its small space requirement, it can not only be permanently installed in the housing of a dry shaving apparatus, but also advantageously used in the case of a displaceable device with two
