Description

Die Erfindung bezieht sich auf ein Langhaarscherteil, insbesondere für Trockenrasierapparate, mit einem am Scherkopf angeordneten Scherkamm und einer hin- und herbewegbaren, gezahnten Scherklinge, welche von einer am Scherkopfrahmen abgestützten Andrückfeder über einen einarmigen Andrückhebel, welcher an der Scherklinge und dem Scherkopfrahmen abgestützt ist, in Anlage an den Scherkamm gehalten ist.The invention relates to a long-hair shear part, in particular for dry shavers, with a shaving comb arranged on the shaving head and a toothed shaving blade which can be moved back and forth, which is supported by a pressure spring supported on the shaving head frame via a single-arm pressure lever which is supported on the shaving blade and the shaving head frame. is held in contact with the shear comb.

Ein generelles Problem von Langhaarscherteilen besteht darin, daß ihre beiden Schneidelemente, der Scherkamm und die Scherklinge, über ihre ganze Länge einwandfrei unter möglichst gleichmäßigem Anpreßdruck aneinanderliegen müssen, ohne daß dadurch das Langhaarscherteil zu schwergängig wird, so daß die notwendigerweise auftretenden Reibkräfte mit möglichst geringen Antriebskräften überwunden werden können. Zu diesem Zweck läßt man die Andruckfeder nicht mehr direkt auf die bewegliche Scherklinge einwirken sondern über den eingangs genannten Andrückhebel, mit dessen Hilfe jetzt bei Bedarf die Kraft der Andrückfedern so umgelenkt werden kann, daß sie in Bezug auf die Funktion des Langhaarscherteiles in optimaler Position und Richtung in die Scherklinge eingeleitet wird. Unvermeidliche Reibarbeit des Langhaarscherteils kann auf diese Weise dahin verlagert werden, wo die Scherarbeit geleistet wird, und die Reibung kann dort geringer gehalten werden, wo es nicht auf ein Andrücken der Scherklinge gegen den Scherkamm ankommt, z.B. an der Klingenrückseite. Langhaarscherteile dieser Art können daher generell sehr leichtgängig gehalten werden, wurden bisher aber nur unvollkommen verwirklicht.A general problem of long-hair shear parts is that their two cutting elements, the shaving comb and the shaving blade, have to lie perfectly against one another over their entire length under the most uniform possible contact pressure, without the long-hair shear part becoming too stiff, so that the friction forces that occur with the lowest possible driving forces can be overcome. For this purpose, the pressure spring is no longer allowed to act directly on the movable shear blade but via the pressure lever mentioned at the beginning, with the help of which the force of the pressure springs can now be redirected so that it is in an optimal position and in relation to the function of the long-hair shear part Direction in the shear blade is initiated. Inevitable friction work of the long-hair shear part can thus be shifted to where the shearing work is carried out and the friction can be kept lower where the shaving blade does not need to be pressed against the shaving comb, e.g. on the back of the blade. Long hair trimmer parts of this type can therefore generally be kept very smoothly, but have so far only been realized incompletely.

So dient bei einem bekannten Langhaarscherteil (NL-A-70 15 258) der Andrückhebel gleichzeitig zum Antrieb der beweglichen Scherklinge und ist aus diesem Grunde als zweiarmiger, in seiner Mitte drehbar gelagerter Hebel ausgebildet, bei dem der eine Hebelarm an der Scherklinge anliegt und der andere an einem gehäusefesten Widerlager. Eine auf beide Hebelarmenden drückende, in der Mitte gehäusefest abgestützte Blattfeder hält den Hebel in seiner Anlage. Nachteilig bei dieser Konstruktion, bei der der Hebel zwei Funktionen erfüllen muß, nämlich Andrücken und Bewegen der Scherklinge, ist es, daß sich beide Funktionen behindern, insbesondere, wenn das Drehlager des Hebels nur einen Freiheitsgrad aufweist und beide Bewegungsachsen senkrecht zueinander gerichtet sind; bewegt sich der Hebel in Andrückrichtung verklemmt sich zwangsläufig das Lager und das Langhaarscherteil wird schwergängig und hat wieder wie vorher die unerwünschte erhöhte Reibung.For example, in a known long-hair shear part (NL-A-70 15 258) the pressure lever serves to drive the movable shear blade and is therefore designed as a two-armed lever which is rotatably mounted in its center, in which one lever arm rests on the shear blade and the others on an abutment fixed to the housing. A leaf spring that presses on both ends of the lever arm and is supported in the center of the housing holds the lever in its position. A disadvantage of this construction, in which the lever has to fulfill two functions, namely pressing and moving the shear blade, is that both functions are hindered, in particular if the pivot bearing of the lever has only one degree of freedom and both axes of movement are perpendicular to one another; if the lever moves in the pressing direction, the bearing inevitably jams and the long-hair shear part becomes stiff and has the undesired increased friction as before.

Bei einem anderen bekannten Langhaarscherteil (US-A-3962 785) ist der Andrückhebel mittels zweier umfangsgeschlossener Lager auf einer gehäusefesten Achse schwenkbar und axial verschiebbar angeordnet und wird durch zwei beiderseits des Hebels auf die Achse aufgewickelte Haarnadelfedern in Andrückstellung gedrängt. Auch bei dieser Konstruktion hat der Andrückhebel zwei Funktionen zu erfüllen, nämlich Andrücken und Bewegen der Scherklinge, und konstruktionsbedingt besteht der Nachteil, daß ein erheblicher Anteil der vom Motor aufzubringenden Energie zum Betrieb des Langhaarscherteils als Reibung in den umfangsgeschlossenen Lagern bei der axialen Antriebsbewegung des Andrückhebels und darüberhinaus auch bei der Überwindung des Beigewiderstandes der freien Arme der beiden Haarnadelfedern verlorengeht. Die Erfindung hat die Aufgabe, ein Langhaarscherteil der eingangs genannten Art zu schaffen, das einfach im Aufbau ist, dessen Eigenreibung von vornherein gering gehalten werden kann und das weitgehende Freiheiten in der Gestaltung und in der Anpassung an gegebene geometrische Verhältnisse bietet.In another known long-hair shear part (US-A-3962 785) the pressure lever is pivotally and axially displaceably arranged on two axially closed bearings by means of two circumferentially closed bearings and is urged into the pressure position by two hairpin springs wound onto the axis on both sides of the lever. In this construction too, the pressure lever has two functions, namely pressing and moving the shear blade, and due to the construction there is the disadvantage that a considerable proportion of the energy to be applied by the motor for operating the long-hair shear part as friction in the circumferentially closed bearings during the axial drive movement of the pressure lever and moreover is lost when the free arms of the two hairpin feathers are overcome. The invention has for its object to provide a long-hair shear part of the type mentioned, which is simple in construction, the intrinsic friction of which can be kept low from the outset and which offers extensive freedom in design and adaptation to given geometric conditions.

Die Erfindung löst diese Aufgabe dadurch, daß der Andrückhebel mit einem schneidenartigen Abschnitt in eine prismatische Ausnehmung des Scherkopfrahmens des Trockenrasierapparates eingesetzt und ausschließlich in Andrückrichtung schwenkbar ist. Durch diese Ausgestaltung kann der Andrückhebel mit sehr geringen Reibverlusten die Andrückkraft der Andrückfeder auf die Scherklinge ubertragen. Der Hebel ist zugleich in seiner Lage festgehalten, so daß keine besonderen Befestigungsmittel aber auch keine speziellen umfangsgeschlossenen, mit vermehrter Reibung behafteten Lager für den Andrückhebei erforderlich sind.The invention solves this problem in that the pressing lever with a cutting-like section is inserted into a prismatic recess in the shaving head frame of the dry shaving apparatus and can only be pivoted in the pressing direction. This configuration enables the pressure lever to transmit the pressure force of the pressure spring to the shear blade with very low friction losses. The lever is also held in place, so that no special fastening means but also no special circumferentially closed bearings with increased friction are required for the pressing.

Eine gleichmäßige Andrückkraft über die Breite der Scherklinge erhält man, wenn gemäß einer näheren Ausgestaltung der Erfindung der Andrückhebel gabelförmig ausgebildet ist und dadurch zwei Arme hat, die jeweils sowohl gegen den Scherkopfrahmen als auch gegen die Scherklinge anliegen.A uniform pressing force over the width of the shaving blade is obtained if, according to a more detailed embodiment of the invention, the pressing lever is fork-shaped and thus has two arms, each of which abuts both against the shaving head frame and against the shaving blade.

Vorteilhaft sind jedem Andrückhebel jeweils zwei Andrückfedern zugeordnet, welche sich jeweils gegen einen Arm des Andrückhebels abstützen, und ist der beide Arme verbindende Steg torsionsweich ausgebildet. Die Andrückkräfte werden durch diese Gestaltung der Erfindung von zwei relativ kleinen Federn erzeugt, welche gut im Scherkopfrahmen unterzubringen sind, und beide Arm können sich unabhängig voneinander an der zugeordneten Scherklinge anlegen.Each pressure lever is advantageously assigned two pressure springs, each of which is supported against an arm of the pressure lever, and the web connecting the two arms is designed to be torsionally soft. The pressure forces are generated by this design of the invention of two relatively small springs, which are easy to accommodate in the shaving head frame, and both arms can lie independently on the associated shaving blade.

Eine weitere günstige Ausgestaltung der Erfindung besteht darin, daß die Scherklinge auf der ihrer Verzahnung gegenüberliegenden Seite mit einem schmalen Lappen gegen den Scherkamm anliegt. Durch diese Gestaltung erhält eine lagensichere Dreipunktabstützung der Scherklinge. Die Gefahr eines Verzugs der Scherklinge durch Schleifen ist gering, weil die vordere Fläche der Scherklinge durch die Verzahnung unterbrochen und als hintere Fläche nur der schmale Lappen zu schleifen ist. Die Anlage der Scherklinge an den Scherkamm ist bei dieser Gestaltung auch dann noch gut, wenn sich die Klinge beim Schleifen geringfügig verwinden sollte.Another advantageous embodiment of the invention consists in that the shear blade abuts against the shear comb on the side opposite its toothing with a narrow rag. This design provides the three-point support of the shaving blade with secure position. The risk of warping the shear blade by grinding is low because the front one Surface of the shear blade is interrupted by the toothing and only the narrow rag is to be ground as the rear surface. With this design, the contact of the shaving blade to the shaving comb is still good even if the blade should twist slightly during grinding.

Das Problem des Verziehens des Scherkammes beim Schleifen kann gemäß einer anderen Ausgestaltung dadurch gelöst werden, daß der Scherkamm ebenfalls einen schmalen Lappen hat, gegen den der Lappen der Scherklinge anliegt. Aus optischen Gründen ist es bei dieser Ausgestaltung zweckmäßig, eine Abdeckung oberhalb des Scherkammes vorzusehen.According to another embodiment, the problem of warping the shaving comb during grinding can be solved in that the shaving comb also has a narrow tab against which the tab of the cutting blade rests. For optical reasons, it is expedient in this embodiment to provide a cover above the shear comb.

Gemäß einer anderen Ausgestaltung der Erfindung ist der Scherkamm auf seiner seinen Zinken abgewandten Seite verzahnt oder gezinkt. Auch diese Maßnahme dient dazu, ein Verziehen des Scherkammes durch das Schleifen zu verhindern.According to another embodiment of the invention, the shear comb is toothed or pronged on its side facing away from its prongs. This measure also serves to prevent the shaving comb from warping due to the grinding.

Die Erfindung läßt zahlreiche Ausführungsmöglichkeiten zu. Eine davon ist in der Zeichnung schematisch dargestellt und wird nachfolgend beschrieben. Es zeigen

  • Figur 1 einen Querschnitt durch den Scherkopf eines Trockenrasierapparates mit zwei Langhaarscherteilen,
  • Figur 2 eine Draufsicht auf einen Teil einer im rechten Teil der Figur 1 dargestellten Scherklinge des einen Langhaarscherteiles,
  • Figur 3 eine Ansicht eines für den erfindungsgemäßen Langhaarscherteil vorgesehenen Andrückhebels,
  • Figur 4 einen Schnitt durch den Andrückhebel gemäß Figur 3 entlang der Linie IV-IV in vergrößertem Maßstab.
The invention allows numerous design options. One of them is shown schematically in the drawing and is described below. Show it
  • FIG. 1 shows a cross section through the shaving head of a dry shaving apparatus with two long-hair shears,
  • FIG. 2 shows a plan view of part of a shear blade of one long-hair shear part, shown in the right part of FIG. 1,
  • FIG. 3 shows a view of a pressure lever provided for the long-hair shear part according to the invention,
  • 4 shows a section through the pressure lever according to Figure 3 along the line IV-IV on an enlarged scale.

In Figur 1 ist schematisch ein Scherkopf 1 dargestellt, welcher mittels einer Feder 2 in Anlage an eine Scherfolie gehalten ist. Durch einen Schwinghebel4 ist der Scherkopf 1 in eine senkrecht zur Ebene der Zeichnung verlaufende hin-und hergehende Bewegung versetzbar.FIG. 1 schematically shows a shaving head 1 which is held in contact with a shaving foil by means of a spring 2. The shaving head 1 can be set in a reciprocating movement perpendicular to the plane of the drawing by means of a rocking lever 4.

Die Scherfolie 3 ist auf übliche, nicht dargestellte Weise innerhalb eines Scherkopfrahmens 5 gehalten. Auf beiden Seiten des Scherkopfrahmens 5 ist jeweils ein Langhaarscherteil und 7 angeordnet. Beide Langhaarscherteile 6 und 7 sind funktionell gleich gestaltet, so daß im folgenden nur das Langhaarscherteil 7 detailliert beschrieben wird.The shaving foil 3 is held in a usual manner, not shown, within a shaving head frame 5. On both sides of the shaving head frame 5 a long-hair shear part and 7 is arranged. Both long-hair shear parts 6 and 7 are designed functionally the same, so that only the long-hair shear part 7 is described in detail below.

Das Langhaarscherteil7 7 hat einen Scherkamm 8, mit Zinken 9, welcher fest mit dem Scherkopfrahmen 5 verbunden ist. Unterhalb des Scherkammes 8 befindet sich eine Scherklinge 10 mit einer Verzahnung 11, welche entsprechend den Zinken 9 gestaltet ist. Ein Andrückhebell2 liegt einerseits nahe der Verzahnung 11 mit einem Anlageabschnitt 13 gegen die Scherklinge 10, andererseits mit einem schneideartigen Abschnitt 14 in eine prismatische Ausnehmung 15 des Scherkopfrahmens 5 an. Eine Andrückfeder 16, welche sich in einem Sackloch 17 des Scherkopfrahmens 5 befindet, ragt in eine Vertiefung 18 des Andrückhebels 12. Diese Vertiefung 18 ist am Andrückhebel 12 zwischen seinem Anlageabschnitt 13 und dem schneidenartigen Abschnitt 14 vorgesehen. Deshalb wird durch die Kraft P der Andrückfeder 16 der Andrückhebel 12 um seinen schneidenartigen Abschnitt 14 verschwenkt, so daß sein Anlageabschnitt 13 nahe der Verzahnung 11 gegen die Scherklinge 10 drückt. Der Andrückhebei 12 zerlegt dabei die Kräfte der Andrückfeder 16 derart, daß die Andrückkraft in etwa rechtwinklig in die Schneidklinge 10 geleitet wird, was besonders deutlich bei dem in Figur 1 links dargestellten Langhaarscherteil6 6 zu erkennen ist, vgl. Wirkungslinien A und B.The Langhaarscherteil7 7 has a shaving comb 8, with prongs 9, which is firmly connected to the shaving head frame 5. Below the shear comb 8 there is a shear blade 10 with teeth 11, which is designed in accordance with the prongs 9. A pressure lever 2 lies on the one hand near the toothing 11 with a contact section 13 against the shear blade 10, and on the other hand with a cutting-like section 14 in a prismatic recess 15 of the shaving head frame 5. A pressure spring 16, which is located in a blind hole 17 of the shaving head frame 5, projects into a depression 18 in the pressure lever 12. This depression 18 is provided on the pressure lever 12 between its contact section 13 and the cutting-like section 14. Therefore, by the force P of the pressure spring 16, the pressure lever 12 is pivoted about its cutting-like section 14, so that its contact section 13 presses against the shear blade 10 near the toothing 11. The pressing lever 12 breaks down the forces of the pressing spring 16 in such a way that the pressing force is guided into the cutting blade 10 at approximately a right angle, which can be seen particularly clearly in the long-hair shear part 6 6 shown on the left in FIG. 1, cf. Lines of action A and B.

Wie Figur 2 zeigt, hat die Scherklinge 10 einen Lappen 20 auf ihrer der Verzahnung 11 gegenüberliegenden Seite. Dieser ist zum Scherkamm 8 hin hochgezogen und liegt gegen einen entsprechenden Lappen 21 des Scherkammes 8 an.As FIG. 2 shows, the shear blade 10 has a tab 20 on its side opposite the toothing 11. This is pulled up to the shear comb 8 and bears against a corresponding tab 21 of the shear comb 8.

Durch diese Gestaltung berühren sich der Scherkamm 8 und die Scherklinge 10 nur im Bereich der Zinken 9 bzw. Verzahnung 11 und mit den Lappen 20 und 21.As a result of this design, the shaving comb 8 and the shaving blade 10 touch only in the area of the prongs 9 or teeth 11 and with the tabs 20 and 21.

Der Scherkamm und die Scherklinge des Langhaarscherteiles 6 sind vorzugsweise ebenfalls mit jeweils einem der Lappen 20 und 21 entsprechenden Lappen versehen, wie dies aus der Zeichnung deutlich erkennbar ist.The shaving comb and the shaving blade of the long-hair shear part 6 are preferably also each provided with one of the tabs 20 and 21 corresponding tabs, as can be clearly seen from the drawing.

Die Fig. und 4 zeigen die Gestaltung des Andrückhebels 12 des Langhaarscherteiles 7. Der Andrückhebel 12 ist gabelförmig gestaltet und hat zwei Arme 23, 24, welche durch einen Verbindungssteg 25 miteinander verbunden sind. Jeder Arm 23, 24 hat den schneidenartigen Abschnitt 14, mit dem er in die Ausnehmung 15 des Scherkopfrahmens 5 greift, und den Andrückabschnitt 13, mit dem er gegen die Scherklinge 10 anliegt. Zwischen diesen Abschnitten 14, 13 ist die Vertiefung 18 in jedem Arm 23, 24 vorgesehen, welche jeweils die Andrückfeder 16 aufnimmt.FIGS. 4 and 4 show the design of the pressure lever 12 of the long-hair shear part 7. The pressure lever 12 is fork-shaped and has two arms 23, 24 which are connected to one another by a connecting web 25. Each arm 23, 24 has the cutting-like section 14, with which it engages in the recess 15 of the shaving head frame 5, and the pressing section 13, with which it bears against the shaving blade 10. Between these sections 14, 13, the recess 18 is provided in each arm 23, 24, which receives the pressure spring 16 in each case.

Der Verbindungssteg 25 ist zweckmäßig torsionsweich ausgebildet und erlaubt damit eine unabhängige Anlage der Arme 23 und 24 an der Scherklinge.The connecting web 25 is expediently designed to be torsionally soft and thus allows the arms 23 and 24 to rest independently on the shear blade.
