Description

Die Erfindung bezieht sich auf einen Scherteil für Trockenrasierapparate und Haarschneidemaschinen mit schlitzförmigen Haareinlaßöffnungen, die eine Einfädelzone und eine von einem bewegten Scherteil überstrichene Schneidzone aufweisen.The invention relates to a shaving part for dry shavers and hair clippers with slit-shaped hair inlet openings, which have a threading zone and a cutting zone covered by a moving shear part.

Solche Scherteile können aus Flachmaterial ausgearbeitete oder durch Biegen dünner Bleche hergestellte Scherkämme mit einseitig offenen Schlitzen sein, es können aber auch Scherfolien sein, in denen die Haareinlaßöffnungen als umfangsgeschlossene Schlitze angebracht sind.Such shaving parts can be shear combs made from flat material or produced by bending thin metal sheets with slots open on one side, but they can also be shaving foils in which the hair inlet openings are provided as circumferentially closed slots.

Scherteile dieser Art, die vorwiegend auch zum Entfernen von Haaren an weichen, nachgiebigen Hautpartien, z.B. am Hals und in den Achselhöhlen, verwendet werden, sind allgemein bekannt (US-A-22 92 858). Dabei besteht das Problem, daß mit den Haaren auch kleine Hautfältchen wellenförmig in die Einlaßöffnungen gelangen und in der Schneidzone verletzt werden. Um diesen Effekt möglichst klein zu halten, kann.man natürlich die Einlaßöffnungen in der Scherfolie relativ klein ausführen, wodurch aber der Schereffekt stark beeinträchtigt wird. Durch das GB-Patent 496 35o ist es auch schon bekannt, die schlitzförmigen Einlaßöffnungen mit einseitiger Krümmung sichelförmig oder schräg zur hauptsächlichen Führungsrichtung des Apparates auszubilden. Damit soll das Eindringen von Hautfalten bis zur Schneidzone erschwert werden. Die Praxis zeigt jedoch, daß durch die Bewegung des Rasierapparates auf der Hautoberfläche in verschiedenen Richtungen oder kreisend eine einmal in eine Einlaßöffnung gelangte Hautfalte auch sehr-gut einem schrägen oder einseitig gekrümmten Verlauf der Einlaßöffnung folgen kann und dadurch leicht bis in die Schneidzone gerät,wo dann die unerwünschte Hautreizung oder Hautverletzung eintritt.Shear parts of this type, which are also mainly used to remove hair on soft, flexible skin areas, for example on the neck and armpits, are generally known (US Pat. No. 2,292,858). The problem is that even small wrinkles on the skin get into the inlet openings in a wave shape and are injured in the cutting zone. In order to keep this effect as small as possible can. of course, the inlet openings in the shaving foil are made relatively small, but the shear effect is greatly impaired. It is also already known from GB patent 496 35o to design the slot-shaped inlet openings with a one-sided curvature in the shape of a crescent or obliquely to the main guiding direction of the apparatus. This is intended to make it more difficult for skin folds to penetrate to the cutting zone. Practice shows, however, that by moving the shaver on the surface of the skin in different directions or circling, a skin fold that has once entered an inlet opening can also very well follow an oblique or one-sided curved course of the inlet opening and thereby easily get into the cutting zone, where then the unwanted skin irritation or skin injury occurs.

Der Erfindung liegt die Aufgabe zugrunde, ein Scherteil der eingangs genannten Art derart zu gestalten, daß einerseits ein hautnahes Abrasieren von Haaren möglich ist und andererseits Hautverletzungen oder Hautreizungen weitgehend vermieden werden.The invention has for its object to design a shear part of the type mentioned in such a way that on the one hand close-up shaving of hair is possible and on the other hand skin injuries or skin irritation are largely avoided.

Die Erfindung löst diese Aufgabe dadurch, daß in Richtung des Einfädelweges vor der Schneidzone mindestens eine im wesentlichen quer zur Längsachse der schlitzförmigen Haareinlaßöffnung gerichtete Anlaufkante angebracht ist, um die der Einfädelweg mit mindestens zweimaligem Richtungswechsel herumgeführt ist.The invention solves this problem in that in the direction of the threading path in front of the cutting zone there is at least one leading edge which is directed essentially transversely to the longitudinal axis of the slit-shaped hair inlet opening and around which the threading path is guided with at least two changes of direction.

Der Hauptvorteil des erfindungsgemäßen Scherteiles liegt darin, daß ein hautnahes Schneiden von Körperhaaren möglich wird, ohne daß dabei kleine Hautfältchen in die Schneidzone des Rasierapparates gelangen können und dadurch eine Hautverletzung oder Hautreizung eintritt. Die durch die Einfädelzone wellenartig einfließende Haut wird durch die als Bremsschwelle wirkende Anlaufkante aufgefangen und durch die zweimalige Umlenkung des Einfädelweges daran gehindert, die Schneidzone auf direktem Wege zu erreichen; dadurch wird die bei Scherteilen mit Haareinlaßöffnungen bekannter Gestaltung für unvermeidlich gehaltene Hautreizung oder Hautverletzung ganz wesentlich vermindert.The main advantage of the shaving part according to the invention is that body hair can be cut close to the skin without small skin wrinkles getting into the cutting zone of the shaving apparatus and thereby causing skin injury or skin irritation. The skin flowing in through the threading zone is caught by the leading edge, which acts as a braking threshold, and is prevented from reaching the cutting zone directly by the double deflection of the threading path; as a result, the design known in the case of shear parts with hair inlet openings for skin irritation or skin injury which is inevitably kept is considerably reduced.

Um den Haareinlaß in die öffnungen des Scherteils zu verbessern, wird die Einfädelzone häufig breiter ausgebildet als die Schneidzone; da aber in diesem Falle auch Hautfältchen besser in den Haareinlaßöffnungen eindringen können, ist nach einer vorteilhaften Ausbildungsform der Erfindung die Anlaufkante durch einen Vorsprung gebildet, der die Schneidzone abdeckt und eine weitere, zur ersten versetzte Anlaufkante vorgesehen ist, um die der Einfädelweg labyrinthartig herumgeführt ist. Die beiden versetzt zueinander liegenden Anlaufkanten und der viermalige Richtungswechsel des Einfädelweges um beide Anlaufkanten herum gewährleisten mit Sicherheit das Abbremsen und Zurückhalten der in den Einfädelzone eingedrungenen Hautf ältchen.In order to improve the hair inlet into the openings of the shaving part, the threading zone is often made wider than the cutting zone; but since in this case skin wrinkles can penetrate better into the hair inlet openings, according to an advantageous embodiment of the invention the leading edge is formed by a projection which covers the cutting zone and a further leading edge offset from the first is provided, around which the threading path is guided like a labyrinth . The two staggered leading edges and the four-fold change of direction of the threading path around both leading edges ensure with certainty that the skin wrinkles that have penetrated into the threading zone are slowed down and held back.

Wird auf einer symmetrischen Anordnung und Ausbildung der Haareinlaßöffnung und auf eine höhere Schneidleistung des Scherteiles Wert gelegt, ist nach einer weiteren vorteilhaften Ausbildungsform der Erfindung vorgesehen, daß jede Haareinlaßöffnung zwei durch einen Steg voneinander getrennte, parallele Schneidzonen mit einer gemeinsamen erweiterten Einfädelzone in symmetrischer Anordnung aufweist, daß zwei gegeneinander gerichtete, die Schneidzone abdeckende, Anlaufkanten bildende Vorsprünge vorgesehen sind und daß die Stirnflanke des Steges als weitere Anlaufkante der öffnung zwischen den Vorsprüngen gegenüberliegt. Auch diese Ausbildungsform gewährleistet ein Abbremsen und Zurückhalten eingedrungener Hautfältchen zunächst an den beiden Anlaufkanten der Vorsprünge und danach an den Anlaufkanten der Stirnfläche des Steges; auch hier ändert der Einfädelweg vor und nach seiner Trennung zweimal seine Richtung.If value is placed on a symmetrical arrangement and design of the hair inlet opening and on a higher cutting performance of the shaving part, it is provided according to a further advantageous embodiment of the invention that each hair inlet opening has two parallel cutting zones separated from one another by a web and having a common one extended threading zone in a symmetrical arrangement that two mutually directed projections covering the cutting zone are provided, and that the end flank of the web, as a further contact edge, is opposite the opening between the projections. This form of training also ensures that penetrated skin wrinkles are slowed down and retained, first on the two leading edges of the projections and then on the leading edges of the end face of the web; here too the threading path changes direction twice before and after its separation.

In Fig..l sind die beiden zusammenwirkenden Scherteile eines Trockenrasierapparates oder einer Haarschneidemaschine beliebiger, bekannter Bauart, die zum Abschneiden längerer Körperhaare, insbesondere für kosmetische Zwecke dienen, im Schnitt dargestellt, und zwar das ruhende Scherteil 1, das im wesentlichen aus einem V-förmig gebogenen Blech besteht und mit schlitzartigen Haareinlaßöffnungen 2 versehen ist, und das mit kammartigem Zähnen 3 versehene bewegte Scherteil 4. . Die Haareinlaßöffnungen 2, deren detaillierte Gestaltung sich aus den Fig. 2, 3 und 4 ergibt, haben eine Einfädelzone 5 und eine Schneidzone 6, die vom bewegten Scherteil 4 überstrichen wird.In Fig..l the two interacting shear parts of a dry shaver or a hair clipper of any known type, which are used for cutting longer body hair, in particular for cosmetic purposes, are shown in section, namely the resting shear part 1, which essentially consists of a V- There is a bent sheet metal and is provided with slot-like hair inlet openings 2, and the moving shear part 4 provided with comb-like teeth 3. The hair inlet openings 2, the detailed design of which is shown in FIGS. 2, 3 and 4, have a threading zone 5 and a cutting zone 6, which is swept by the moving shear part 4.

Nach der in Fig. 2 dargestellten Ausführungsform ist die Einfädelzone 5 der Haareinlaßöffnung 2 nicht wesentlich breiter als die Schneid-' zone 6, diese ist gegenüber der Einfädelzone 5 mit ihrer Längsachse 7 aber soweit seitlich versetzt, daß der Einfädelweg 8 einen zweimaligen Richtungswechsel erfährt und noch vor der Schneidzone 6 - in Einfädelrichtung gesehen - eine quer zur Längsachse 7 gerichteten Anlaufkante 9 entsteht, die wellenartig einfließende Hautfältchen abbremst und daran hindert, die Schneidzone auf direktem Wege zu erreichen.According to the embodiment shown in FIG. 2, the threading zone 5 of the hair inlet opening 2 is not substantially wider than the cutting zone 6, but this is laterally offset with respect to the threading zone 5 with its longitudinal axis 7 to such an extent that the threading path 8 undergoes a two-way change of direction and Even before the cutting zone 6 - seen in the threading direction - a leading edge 9 directed transversely to the longitudinal axis 7 is created, which brakes wrinkled skin wrinkles and prevents them from reaching the cutting zone in a direct way.

Bei dem Ausführungsbeispiel gemäß Fig. 3 ist die Einfädelzone 5.1 gegenüber der Schneidzone 6.1 wesentlich erweitert. An dem einen Rand lo der Einfädelzone 5.1 ist ein quer zur Längsachse 7.1 gerichteter Vorsprung 11 angebracht, der soweit zum gegenüberliegenden Rand 12 reicht, daß er die Schneidzone 6.1 abdeckt. Der Einfädelweg 8.1 ist um diesen Vorsprung 11 labyrinthartig mit vierfachem Richtungswechsel geführt. Der Vorsprung 11 bildet - in Einfädelrichtung gesehen - eine erste Anlaufkante 13, der am gegenüberliegenden Rand 12 eine zweite, versetzte Anlaufkante 14, die ebenfalls im wesentlichen quer zur Längsachse 7.1 gerichtet ist, zugeordnet ist.In the exemplary embodiment according to FIG. 3, the threading zone 5.1 is significantly expanded compared to the cutting zone 6.1. At one edge lo of the threading zone 5.1 there is a projection 11 directed transversely to the longitudinal axis 7.1, which extends to the opposite edge 12 so far that it covers the cutting zone 6.1. The threading path 8.1 is guided around this projection 11 in a labyrinthine manner with a four-fold change of direction. The projection 11 forms - seen in the threading direction - a first leading edge 13, which is assigned a second, offset leading edge 14 on the opposite edge 12, which is also directed essentially transversely to the longitudinal axis 7.1.

Die Haareinlasöffnungnach Fig. 4 hat eine erweiterte Einfädelzone 5.2 und zwei durch einen Steg 15 getrennte, parallele Schneidzone 6.2 in symmetrischer Anordnung zur Längsachse 7.2. An den Rändern 16 und 17 der Haareinlaßöffnung 2 sind zwei gegeneinander gerichtete Vorsprünge 18 und 19 angebracht, die eine öffnung 2o freilassen, deren Breite etwa der Breite einer Schneidzone 6.2 entspricht. Dieser Öffnung 2o liegt die Stirnseite des Steges 15 gegenüber und bildet neben den Anlaufkanten 21 und 22 der Vorsprünge 18 und 19 eine dritte Anlaufkante 23. Auch bei dieser Ausbildungsform der Haareinlaßöffnung versperren die Vorsprünge 18 und 19 den direkten Weg von der Einfädelzone 5.2 in die Schneidzonen 6.2 und erzwingen einen mehrfachen Richtungswechsel des Einfädelweges 8.2. Einfließende Hautfältchen werden an den drei Anlaufkanten 21, 22 und 23 abgebremst und aufgehalten.4 has an extended threading zone 5.2 and two parallel cutting zone 6.2 separated by a web 15 in a symmetrical arrangement with respect to the longitudinal axis 7.2. At the edges 16 and 17 of the hair inlet opening 2 two mutually directed projections 18 and 19 are attached, which leave an opening 2o, the width of which corresponds approximately to the width of a cutting zone 6.2. This opening 2o is located opposite the end face of the web 15 and forms, in addition to the leading edges 21 and 22 of the projections 18 and 19, a third leading edge 23. Also in this embodiment of the hair inlet opening, the projections 18 and 19 block the direct path from the threading zone 5.2 into the cutting zones 6.2 and force a multiple change of direction of the threading path 8.2. Incoming wrinkles on the skin are braked and stopped at the three leading edges 21, 22 and 23.
