Definitions
- the invention relates to a cutting device for cutting hair according to the preamble of patent claim 1.
- Such a cutting device is from the US 4,803,780 known. However, its projection-provided blade is not driven.
- a shearing system in which the existing of an upper and lower blade cutting device is preceded by a feeder, which is oscillated relative to the upper blade and forth.
- the delivery device should be as thorough and gentle on the hair as possible, and on the other hand, long and / or tight-fitting hairs should in particular be grasped and removed by the shearing system with a comparatively high degree of probability.
- the feeder forms an additional reciprocating unit from the drive system which is presented to the actual cutter.
- the object of the invention is therefore to provide a cutting device, in which with particularly simple means also closely fitting to the skin of hair caught by the teeth, threaded into the tooth spaces and finally cut off from the cutting device.
- the edges on the teeth of the other, re-adjusted blade can be sharp-edged. Sharp-edged blades improve the erection and threading of the hair into the cutting gap, but would stress the surface of the skin more if not according to the invention, the protrusions would be located upstream of the trailing tooth tips. This results in a better shaving result with greater skin protection.
- the blade movement expediently depends on the outer contour of the toothing and can therefore be rectilinear, curved or circular.
- the blade provided with the projections is acted upon by the oscillating reciprocating movement, which further favors the threading of the hair in the cutting gaps.
- the other blade forms the slender comb
- the blade provided with the projections forms the actual knife of the cutting device.
- the hairs are erected by the reciprocating motion of the projections and the tooth gaps of the other Blade, namely the delicate comb supplied, where they are then finally aligned, clamped between the teeth and cut off.
- the projections are rounded all round and thus protect the skin from the sharp edges of the other, behind blade, namely the comb.
- the moving on the skin projections could be used by special design targeted for exfoliation or loosening of the hair in the hair channel. Studies with the embodiment of the invention have shown that the loosening of the hair improved by the projections and thus just the thoroughness of the shave is increased.
- the projections are formed in their longitudinal direction pin, pin or columnar elevations formed, the outwardly facing side wall passes continuously into the side surfaces of the respective tooth.
- the side wall of a projection thus goes straight into the side surface of a tooth and forms an extended tip together with the respective tooth.
- the cross section of a projection may be circular, oval, polygonal or otherwise formed, it is only important that during shaving the skin surface meets a rounded to the tip projection so as not to be injured.
- the cross-sections of the projections as well as the tips of the teeth of the knife may also become blunt towards the edges of the blades to effect the greatest possible skin protection.
- the projections may also be formed as rounded nubs.
- claim 3 forms the final with the side surface of a tooth lateral surface of a projection with the side surface of the respective tooth a common plane. This avoids step transitions from the projections to the side surfaces of the teeth at the outwardly facing portions, which better protects the surface of an operator's skin during shaving.
- the side wall of a projection tapers towards its free end. This allows a simpler manufacture of the blade, which is preferably produced in the embossing-punching process.
- the protrusions are preferably formed out of the plane of the teeth upwards during the embossing process. Then the teeth are punched out or cut out with a laser beam.
- the projections are provided at their end faces with outwardly curved end portions. By rounded outward free ends of the projections thus the skin is better protected during shaving.
- the cutting device according to the invention is used as a trimmer or contour cutter, that is, the side surfaces formed at the tips of the teeth form the sliding surface opposite the skin surface of an operator.
- trimmer or contour cutter that is, the side surfaces formed at the tips of the teeth form the sliding surface opposite the skin surface of an operator.
- Such vertical flared trimmers are usually mounted on the front of a razor housing, as is the case for example in the marketed by the applicant "Braun Synchro".
- the trimmer can also be folded out vertically, for example, for its use from the side wall of a razor housing.
- the cutting device according to the invention can also be formed on a device that is used as a beard trimmer.
- the cutting device is a short-hair cutting system upstream or downstream, ie, in one movement first engages the cutting device according to the invention, the longer hair, while then the fine cut by the downstream short-hair cutting system (consisting of perforated film and a back and forth lower knife) takes place.
- the cutting device according to the invention forms a central cutter, which is stored between two Kurzhaarschneidesystemen.
- the cutting device according to the invention on both sides towards freely expiring teeth, wherein protrude at the reciprocating blade at the ends of the teeth, the projections up to the comb.
- the teeth of the blade which can be brought into contact with the skin are sheathed by the protrusions during the shaving process in both shaving directions.
- a central cutter without the subject of the invention is, for example, the "360 ° Complete" shaver Braun, which has long been marketed by the Applicant. Pulsonic "known. In these razor types, the cutting device according to the invention could be used instead of the middle cutter known there.
- the cutting device 1 consists of an upper blade 2 and a lower blade 3, which via successive sliding contact surfaces 4, 5 ( Fig. 2 ) are in sliding contact.
- Comb-like teeth 8, 9 arranged in rows of teeth 27, 28, the tips 10, 11 on straight, mutually parallel lines, 36, 12 (shown here in phantom).
- the tooth base 13 of all teeth 8, 9 lies on the straight line 37 (lower line not visible), wherein all the lines 36, 12, 37 are preferably parallel to each other.
- the upper blade 2 forms after the FIGS. 1 to 3 in this embodiment, the actual comb of the cutting device 1, while the lower blade 3 forms the knife.
- the knife 3 can be reciprocated in the directions P oscillating, wherein the movement P is preferably perpendicular or transverse to the extension of the teeth 8, 9 and parallel to the line 12.
- a drive part not shown
- an electric motor not shown
- connectable coupling element 14 is arranged, via which the knife 3 is set in the reciprocating vibrations P.
- a pressing device not shown in the drawing, preferably one or more springs, formed in the cutting device 1, through which the blade 3 is pressed with its contact surface 5 against the contact surface 4 of the upper blade 2.
- the teeth 9 of the lower blade 3 extend beyond the teeth 10 of the upper blade 2 forward beyond the portion 15. This can be achieved on the one hand by the fact that the lower teeth 9 are longer than the upper teeth 8 or on the other hand in that all the teeth 8, 9 are the same length, but offset from each other by the measure (a).
- the projections 17 protect the adjacent tips 10 of the teeth 8 of the upper blade 2 when the skin surface 29 is pressed against the tooth tips 11 during shaving in the direction B2.
- the projections 17 are preferably pin-shaped or column-shaped and have at their free ends convexly (upward) arched end portions 18 in the form of caps, which are preferably aligned with the tops 21 of the tooth tips 10, slightly above or below.
- the projections 17 form on the circumference a lateral surface 19, which without stage ( FIGS. 2 and 3 ), so straight into the side surfaces 20 of the sections 15 run, ie, there are no steps.
- the cutting device 1 may also be preferably used as a trimmer, wherein it then preferably at the front of a razor housing (not shown) protrudes and is guided perpendicularly from the front against the tips 10, 11 to the skin surface to be shaved 24. The shaving movement then goes back and forth in direction C.
- the lower blade 3 is driven to oscillate. But it can also be driven only the upper blade 2 instead of the lower blade 3. It is also conceivable that both blades 2, 3 are moved in an oscillating manner. As a further variant, it is also possible that one of the two blades 2 or 3 is driven, while the other blade is swinging in the housing (not shown) of a razor, so that oppositely oscillating movements can increase the cutting action.
- the cutting device 1 shown can be used, for example, in the razor "Braun Synchro", which has long been marketed by the applicant, instead of the trimmer provided there, in which case the razor moves in the direction C with the tooth tips 11 on the skin surface 24 (FIG. Fig. 2 ) is guided along.
- the cutting device 1 can also be used as a central cutter, as it is for example in that of the Applicant razor "Braun 360 ° Complete” or "Braun Pulsonic” is used, in which case the razor is moved in the direction B on the skin surface 29 (FIG. Fig. 2 ) is guided along.
- the teeth 8, particularly sharp side edges 30, 31 at the junction of the side surfaces 20 to the top 21 and the contact surface 4 have, which also applies to the tips 10 of the upper blade 2 as a comb. This results in a better threading of the hair in the comb, thus improving the shaving result.

Description
Die Erfindung betrifft eine Schneideinrichtung zum Schneiden von Haaren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cutting device for cutting hair according to the preamble of patent claim 1.
Eine derartige Schneideinrichtung ist aus der

Schließlich ist noch aus der
Aufgabe der Erfindung ist es nun, eine Schneideinrichtung zu schaffen, bei der mit besonders einfachen Mitteln auch eng an der Haut anliegende Haare besser von den Zähnen erfaßt, in die Zahnlücken eingefädelt und schließlich von der Schneideinrichtung abgeschnitten werden.The object of the invention is therefore to provide a cutting device, in which with particularly simple means also closely fitting to the skin of hair caught by the teeth, threaded into the tooth spaces and finally cut off from the cutting device.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Dadurch, daß auf der Seite der Kontaktflächen an den überstehenden Abschnitten der Zähne der einen Klinge Vorsprünge ausgebildet sind, sind diese den Zähnen der anderen Klinge vorangestellt bzw. vorgelagert. Beim Rasiervorgang, also bei der Bewegung, bei der die unrasierte Haut zunächst erst gegen die Spitzen der längeren Zähne gerät, werden durch die Vorsprünge die Haare besser erfaßt, aufgerichtet und leichter den Schneidspalten zugeführt, was zu einem besseren Rasierergebnis führt. Da durch die Vorsprünge die Spitzen der dahinter liegenden Zähne der anderen Klinge mehr geschützt sind, werden sie auch weniger in Kontakt mit der Hautoberfläche gebracht, was eine die Haut mehr schonende Rasur ergibt. Durch die Erfindung bedarf es keiner zusätzlichen Bauteile, wie Umlenkhebel oder Achsen, was den Fertigungsaufwand reduziert.This object is achieved by the characterizing features of claim 1. Characterized in that on the side of the contact surfaces on the protruding portions of the teeth of a blade projections are formed, these are the teeth of the other blade preceded or upstream. When shaving, so in the movement in which the unshaved skin first against the tips of the longer teeth, the hair is better detected by the projections, erect and easier fed to the cutting gaps, resulting in a better shaving result. Since the projections of the tips of the underlying teeth of the other blade are more protected, they are also less brought into contact with the skin surface, resulting in a skin more gentle shave. The invention requires no additional components, such as lever or axles, which reduces the production cost.
Durch die Erfindung können die Kanten an den Zähnen der anderen, nachgestellten Klinge scharfkantig ausgebildet sein. Scharfkantige Klingen verbessern nämlich das Aufrichten und Einfädeln der Haare in die Schneidspalte, würden aber die Hautoberfläche stärker strapazieren, wenn nicht erfindungsgemäß den nachgestellten Zahnspitzen die Vorsprünge vorgelagert wären. Dadurch ergibt sich also ein besseres Rasierergebnis bei größerer Hautschonung.By the invention, the edges on the teeth of the other, re-adjusted blade can be sharp-edged. Sharp-edged blades improve the erection and threading of the hair into the cutting gap, but would stress the surface of the skin more if not according to the invention, the protrusions would be located upstream of the trailing tooth tips. This results in a better shaving result with greater skin protection.
Die Klingenbewegung richtet sich zweckmäßigerweise nach der Außenkontur der Verzahnung und kann daher geradlinig, bogen- oder kreisförmig sein.The blade movement expediently depends on the outer contour of the toothing and can therefore be rectilinear, curved or circular.
Gemäß den Merkmalen des Patentanspruchs 1 ist die mit den Vorsprüngen versehene Klinge mit der oszillierenden Hin- und Herbewegung beaufschlagt, was das Einfädeln der Haare in die Schneidspalte weiter begünstigt. Dabei bildet die andere Klinge den feingliedrigen Kamm, während die mit den Vorsprüngen versehene Klinge das eigentliche Messer der Schneideinrichtung bildet. Beim Rasiervorgang werden also durch die Hin- und Herbewegung der Vorsprünge die Haare von diesen aufgerichtet und den Zahnlücken der anderen Klinge, nämlich dem feingliedrigen Kamm, zugeführt, wo sie letztendlich dann ausgerichtet, zwischen den Zähnen eingeklemmt und abgeschnitten werden. Die Vorsprünge sind rundum verrundet und schützen so die Haut vor den scharfen Kanten der anderen, dahinter liegenden Klinge, nämlich dem Kamm. Die sich auf der Haut bewegenden Vorsprünge könnten durch spezielle Gestaltung gezielt zum Peeling oder Lockerung der Haare im Haarkanal verwendet werden. Untersuchungen mit der erfindungsgemäßen Ausgestaltung haben gezeigt, daß durch die Vorsprünge das Lockern der Haare verbessert und dadurch eben die Gründlichkeit der Rasur erhöht wird.According to the features of claim 1, the blade provided with the projections is acted upon by the oscillating reciprocating movement, which further favors the threading of the hair in the cutting gaps. In this case, the other blade forms the slender comb, while the blade provided with the projections forms the actual knife of the cutting device. During the shaving process, the hairs are erected by the reciprocating motion of the projections and the tooth gaps of the other Blade, namely the delicate comb supplied, where they are then finally aligned, clamped between the teeth and cut off. The projections are rounded all round and thus protect the skin from the sharp edges of the other, behind blade, namely the comb. The moving on the skin projections could be used by special design targeted for exfoliation or loosening of the hair in the hair channel. Studies with the embodiment of the invention have shown that the loosening of the hair improved by the projections and thus just the thoroughness of the shave is increased.
Gemäß den Merkmalen des Patentanspruches 2 werden die Vorsprünge von in ihrer Längsrichtung zapfen- , stift- oder säulenförmig ausgebildeten Erhebungen gebildet, deren nach außen zeigende Seitenwand stufenlos in die Seitenflächen des jeweiligen Zahnes übergeht. Die Seitenwand eines Vorsprunges geht also eben geradlinig in die Seitenfläche eines Zahnes über und bildet mit dem jeweiligen Zahn gemeinsam eine verlängerte Spitze. Der Querschnitt eines Vorsprunges kann kreisförmig, oval, mehreckig oder sonst wie ausgebildet sein, wichtig ist nur, daß beim Rasiervorgang die Hautoberfläche auf einen zur Spitze gerundeten Vorsprung trifft, um nicht verletzt zu werden. Die Querschnitte der Vorsprünge sowie die Zahnspitzen des Messers können auch zu den Rändern der Klingen hin stumpfer werden, um eine größtmögliche Hautschonung zu bewirken. Die Vorsprünge können auch als gerundete Noppen ausgebildet sein.According to the features of
Nach den Merkmalen des Patentanspruchs 3 bildet die mit der Seitenfläche eines Zahnes abschließende Mantelfläche eines Vorsprungs mit der Seitenfläche des jeweiligen Zahnes eine gemeinsame Ebene. Dadurch werden stufige Übergänge von den Vorsprüngen zu den Seitenflächen der Zähne an den nach außen weisenden Bereichen vermieden, was beim Rasiervorgang die Oberfläche der Haut einer Bedienungsperson besser schont.According to the features of
Gemäß den Merkmalen des Patentanspruchs 4 verjüngt sich die Seitenwand eines Vorsprunges zu seinem freien Ende hin. Dies ermöglicht eine einfachere Herstellung der Klinge, die vorzugsweise im Präge-Stanz-Verfahren hergestellt wird. Dabei werden vorzugsweise beim Prägevorgang die Vorsprünge aus der Ebene der Zähne nach oben heraus geformt. Anschließend werden die Zähne ausgestanzt oder mit einem Laserstrahl ausgeschnitten.According to the features of claim 4, the side wall of a projection tapers towards its free end. This allows a simpler manufacture of the blade, which is preferably produced in the embossing-punching process. In this case, the protrusions are preferably formed out of the plane of the teeth upwards during the embossing process. Then the teeth are punched out or cut out with a laser beam.
Nach den Merkmalen des Patentanspruches 5 sind die Vorsprünge an ihren Stirnseiten mit nach außen gewölbten Endabschnitten versehen. Durch die nach außen gerundeten freien Enden der Vorsprünge wird somit beim Rasiervorgang die Haut besser geschont.According to the features of
Gemäß den Merkmalen des Patentanspruchs 6 wird die erfindungsgemäße Schneideinrichtung als Trimmer oder Konturenschneider verwendet, d.h., die an den Spitzen der Zähne ausgebildeten Seitenflächen bilden die Gleitfläche gegenüber der Hautoberfläche einer Bedienungsperson. Derartige senkrecht ausgestellte Trimmer sind in der Regel an der Vorderseite eines Rasierergehäuses angebracht, wie dies beispielsweise bei dem von der Anmelderin vertriebenen "Braun Synchro" der Fall ist. Der Trimmer kann aber auch beispielsweise zu seinem Gebrauch aus der Seitenwand eines Rasiererghäuses senkrecht herausgeklappt werden. Die erfindungsgemäße Schneideinrichtung kann aber auch an einem Gerät, das als Bartschneider Verwendung findet, ausgebildet sein.According to the features of
Nach den Merkmalen des Patentanspruches 7 bildet diejenige Klinge, an der nicht die Vorsprünge ausgebildet sind, die Kontaktfläche zur Hautoberfläche, d.h., beim Rasiervorgang gleitet die Außenfläche des feingliedrigen Kammes an der Hautoberfläche entlang und bildet somit in dieser Ausführungsform das Obermesser, während die mit den Vorsprüngen versehene Klinge das Untermesser bildet, das vorzugsweise oszillierend hin- und herbewegt werden kann. Gemäß den Merkmalen des Patentanspruchs 9 ist die Schneideinrichtung einem Kurzhaarschneidesystem vor- bzw. nachgelagert ist, d.h., in der einen Bewegung ergreift zunächst die Schneideinrichtung nach der Erfindung die längeren Haare, während anschließend der Feinschnitt durch das nachgelagerte Kurzhaarschneidesystem (bestehend aus perforierter Folie und einem hin und hergehenden Untermesser) erfolgt.According to the features of
In einer anderen Ausführungsform gemäß den Merkmalen des Patentanspruches 8 bildet die erfindungsgemäße Schneideinrichtung einen Mittelschneider, der zwischen zwei Kurzhaarschneidesystemen zwischengelagert ist. Dabei weist die erfindungsgemäße Schneideinrichtung zu beiden Seiten hin frei auslaufende Zähne auf, wobei an der sich hin- und herbewegenden Klinge an den Enden der Zähne die Vorsprünge nach oben zum Kamm ragen. Dadurch sind die Zähne der mit der Haut in Kontakt bringbaren Klinge beim Rasiervorgang in beiden Rasierrichtungen von den Vorsprüngen geschützt nachgelagert, Ein Mittelschneider ohne den Erfindungsgegenstand ist beispielsweise durch den von der Anmelderin seit längerem vertriebenen Rasierer Braun "360° Complete" oder den Rasierer Braun "Pulsonic" bekannt. Bei diesen Rasierertypen könnte anstelle des dort bekannten Mittelschneiders die erfindungsgemäße Schneideinrichtung eingesetzt werden.In another embodiment according to the features of
