Description

Trockenrasierapparat mit einem Gehäuse, einem Antriebssystem und einem Scherkopf, mit mindestens einem bogenförmigen Kurzhaar­schneidsystem und wenigstens einem, diesem zugeordneten Langhaar­schneidsystem.Dry shaving apparatus with a housing, a drive system and a shaving head, with at least one curved short hair cutting system and at least one long hair cutting system assigned to it.

Aus der DE-23 09 342 C2 ist ein Trockenrasierapparat mit einem auf dem Gehäuse starr aufgesetzten Scherkopf bekannt, in dem unter­schiedliche Haarschneidsysteme, und zwar ein Kurzhaarschneidsystem und zwei parallel zum Kurzhaarschneidsystem angeordnete Lang­haarschneidsysteme vorgesehen sind. Der gleichzeitige Einsatz des Kurzhaarschneidsystems mit einem der vorgesehenen Langhaarschneid­systeme erfordert eine sehr genaue Anlage und Führung der beiden Haarschneidsysteme über die Hautfläche und deren unterschiedliche Konturen im Wangen- , Kinn- und Halsbereich durch den Benutzer eines derartigen Rasierapparates. Eine solche relativ komplizier­te, die Handhabung eines Rasierapparates erschwerende Maßarbeit ist dem Benutzer nicht zumutbar.DE-23 09 342 C2 discloses a dry shaving apparatus with a shaving head rigidly mounted on the housing, in which different hair cutting systems, namely a short hair cutting system and two long hair cutting systems arranged parallel to the short hair cutting system, are provided. The simultaneous use of the short hair trimmer system with one of the long hair trimmer systems required requires a very precise installation and guidance of the two hair trimmer systems over the skin surface and their different contours in the cheek, chin and neck area by the user of such a razor. Such a relatively complicated custom work that complicates the handling of a razor is not reasonable for the user.

Aus der EP 00 77 093 A2 ist ein Trockenrasierapparat mit min­destens einem, im Scherkopfrahmen befestigten Siebscherteil und Kammscherteil sowie einer, mit dem Antrieb gekuppelten Unter­messereinheit bekannt. Um einen gleichzeitigen Einsatz von Sieb­scherteil und Kammscherteil zu bewirken, ist der wirksame Teil des Kammscherteils seitlich auskragend an den wirksamen Teil des Schiebscherteils angeschlossen, wobei der Anschlußbereich der bei­den Scherteile aneinander die von diesem wirksamen Teil des Kamm­scherteils festgelegte Ebene mit der Tangentialebene an den wirk­samen Teil des Siebscherteils einen stumpfen Winkel bildet. Für den gleichzeitigen Einsatz von Siebscherteil und Kammscherteil ist es jedoch erforderlich, den Rasierapparat stets in einem be­stimmten Winkel über die jeweilige Kontur der Hautfläche zu füh­ ren, um ein Abheben eines der beiden Scherteile zu vermeiden. Eine derartige präzise Führung des Rasierapparates über die Konturen der Hautfläche erschwert die Handhabung des Rasierapparates er­heblich und führt in der Regel zu einer Verschlechterung der Rasur, da der Benutzer erfahrungsgemäß nicht geneigt ist, die nötige Aufmerksamkeit während der gesamten Zeitdauer des Rasier­vorganges aufzubringen.EP 00 77 093 A2 discloses a dry shaving apparatus with at least one sieve shear part and comb shear part fastened in the shaving head frame and a lower knife unit coupled to the drive. In order to effect simultaneous use of the sieve shear part and the comb shear part, the effective part of the comb shear part is laterally cantilevered to the effective part of the sliding shear part, the connection area of the two shear parts to one another the plane defined by this effective part of the comb shear part with the tangential plane to the active part the screen shear part forms an obtuse angle. However, for the simultaneous use of the sieve shear part and comb shear part, it is necessary to always guide the shaver at a certain angle over the respective contour of the skin surface to avoid lifting one of the two shear parts. Such precise guiding of the shaving apparatus over the contours of the skin surface makes handling of the shaving apparatus considerably difficult and generally leads to a deterioration in the shaving, since experience has shown that the user is not inclined to pay the necessary attention during the entire duration of the shaving process.

Aus der US-PS 32 79 052 ist ein Rasierapparat mit zwei unter­schiedlich ausgebildeten Haarschneidsystemen, bestehend aus einem Kurzhaarschneidsystem und einem Langhaarschneidsystem bekannt, die unabhängig voneinander zum Einsatz gelangen. Zu diesem Zweck sind das Kurzhaarschneidsystem und das Langhaarschneidsystem parallel zueinander verlaufend auf den Seitenflanschen eines Scherkopf­trägers vorgesehen, der zwischen zwei, vom Rasierergehäuse ab­stehenden, federnden Tragarmen angeordnet und mittels in diese eingreifenden Lagerbolzen schwenkbar gelagert ist, wobei die Elastizität der federnden Tragarme derart bemessen ist, daß diese den Scherkopfträger in jeder gewinschten Schwenkposition, insbe­sondere in den beiden durch Anschläge vorgegebenen Extrempositio­nen festhalten, in denen jeweils eines der vorgesehenen Haar­schneidsysteme ein optimales Schneidergebnis erbringen soll. Ein gleichzeitiger und ständiger Einsatz beider Haarschneidsysteme während einer Rasur ist bei diesem Rasierapparat aufgrund des weit unterhalb der Anlageflächen beider Haarschneidsysteme an der Haut­fläche befindlichen Schwenklagers des Scherkopfträgers ausge­schlossen.From US-PS 32 79 052 a shaver with two differently designed hair cutting systems, consisting of a short hair cutting system and a long hair cutting system is known, which are used independently of each other. For this purpose, the short hair cutting system and the long hair cutting system are provided running parallel to one another on the side flanges of a shaving head support which is arranged between two resilient support arms projecting from the razor housing and is pivotably mounted by means of bearing bolts which engage in it, the elasticity of the resilient support arms being dimensioned in this way, that they hold the shaving head carrier in any desired pivot position, in particular in the two extreme positions specified by stops, in which one of the hair cutting systems provided is intended to produce an optimal cutting result. Simultaneous and constant use of both hair cutting systems during a shave is ruled out in this shaving apparatus because of the pivot bearing of the shaving head wearer located on the skin surface far below the contact surfaces of both hair cutting systems.

Fig. 2 zeigt einen Längsschnitt durch den Scherkopf 2 und den obe­ren Teil des Gehäuses 1 des Rasierapparates nach Fig. 1. An dem Gehäuse 1 sind zwei Tragarme 4 und 5 vorgesehen, zwischen denen der Scherkopf 2 um die Schwenkachse Z schwenkbar gelagert ist. In den beiden Schmalseitenwänden 6 und 7 des Scherkopfes 2 sind zur Begrenzung der Schwenkbarkeit des Scherkopfes 2 Führungsnuten 8 und 9 eingeformt, in die an den Tragarmen 4 und 5 vorgesehene Füh­ rungsstifte 10 und 11 eingreifen. Zwischen den Schmalseitenwänden 6 und 7 ist eine an diesen befestigte Schwingbrücke 12 vorgesehen, die von einem, aus dem Gehäuse 1 herausragenden Antriebsstift 13 in eine hin- und hergehende Schwingbewegung versetzt wird. Die Schwingbrücke ist mit einem Kupplungselement 14 zum Betreiben eines nicht dargestellten Langhaarschneidsystems L sowie einem weiteren Kupplungselement 15 zum Betreiben des aus einem Unter­messer 16 und einem Obermesser 17 bestehenden Kurzhaarschneid­systems K versehen. Der Scherkopf 2 ist mittels zweier Gelenkbol­zen 18 und 19, die an den Schmalseitenwänden 6 und 7 vorgesehen sind, in in den Tragarmen 4 und 5 befindlichen Lagerbohrungen 20 und 21 um die Schwenkachse Z schwenkbar gelagert. Die Schwenkachse Z verläuft in Höhe der äußeren Kontur des Obermessers des Kurz­haarschneidsystems K durch die Mittenachsen der Lagerbohrungen 20 und 21 sowie der Gelenkbolzen 18 und 19. Die Figuren 3 bis 6 zei­gen in schematischer Darstellung verschiedene Ausführungsformen und Zuordnungen von Kurzhaar- und Langhaarschneidsystemen, ein­schließlich Achsmittelpunkte für die Schwenkachse Z.Fig. 2 shows a longitudinal section through the shaving head 2 and the upper part of the housing 1 of the shaving apparatus according to Fig. 1. On the housing 1, two support arms 4 and 5 are provided, between which the shaving head 2 is pivotally mounted about the pivot axis Z. In the two narrow side walls 6 and 7 of the shaving head 2 2 guide grooves 8 and 9 are formed to limit the pivotability of the shaving head, in the provided on the support arms 4 and 5 Füh engaging pins 10 and 11. Provided between the narrow side walls 6 and 7 is an oscillating bridge 12 attached to the latter, which is set into a reciprocating oscillating movement by a drive pin 13 protruding from the housing 1. The swing bridge is provided with a coupling element 14 for operating a long hair cutting system L, not shown, and a further coupling element 15 for operating the short hair cutting system K consisting of a lower knife 16 and an upper knife 17. The shaving head 2 is mounted by means of two hinge pins 18 and 19, which are provided on the narrow side walls 6 and 7, in the bearing arms 4 and 5 in the bearing bores 20 and 21 pivotable about the pivot axis Z. The pivot axis Z runs at the level of the outer contour of the upper knife of the short hair cutting system K through the center axes of the bearing bores 20 and 21 and the hinge pins 18 and 19. FIGS. 3 to 6 show a schematic representation of various embodiments and assignments of short hair and long hair cutting systems, including axis center points for the swivel axis Z.

In Fig. 3 ist ein bogenförmiges Kurzhaarschneidsystem K, bestehend aus einem Untermesser 16 und einem Obermesser 17 sowie ein mit zwei Schneidbereichen L₁ und L₂ versehenes Langhaarschneid­system L, bestehend aus einem Schneidkamm 22 und einer Schneid­klinge 23 dargestellt. Mit G₁ ist eine, an die äußere Kante des Schneidbereiches L₁ des schräg gestellten Langhaarschneidsystems L sowie die äußere Kontur des Kurzhaarschneidsystems berührende Gerade bezeichnet. Mit A ist der Abstand der äußersten Berührungs­punkte B₁ und B₂ der das Langhaarschneidsystem L und das Kurz­haarschneidsystem K berührenden Geraden G₁ bezeichnet. Eine, die Gerade G₁ in der Mitte des Abstandes A rechtwinklig schneidende Gerade G₂ führt zu dem Schnittpunkt SP.In Fig. 3 an arcuate short hair cutting system K, consisting of a lower knife 16 and an upper knife 17 and a long hair cutting system L provided with two cutting areas L 1 and L 2, consisting of a cutting comb 22 and a cutting blade 23 is shown. With G₁, a straight line is referred to the outer edge of the cutting area L₁ of the oblique long hair cutting system L and the outer contour of the short hair cutting system. With A the distance between the outermost points of contact B₁ and B₂ of the long hair trimming system L and the short hair trimming system K touching straight lines G₁ is designated. A, the straight line G₁ in the middle of the distance A intersecting straight line G₂ leads to the intersection SP.

Der Schnittpunkt SP stellt den Achsmittelpunkt für die in Längs­richtung eines am Gehäuse 1 schwenkbar gelagerten Scherkopfes Z verlaufende Schwenkachse Z dar und dient als Anhaltspunkt für den Umgebungsbereich, innerhalb dessen die Schwenkachse Z ebenfalls vorgesehen werden kann. Das bogenförmige Kurzhaarschneidsystem K weist einen scheraktiven Bereich auf, der sich, ausgehend vom Be­rührungspunkt B₁, in beide Richtungen auf der Bogenform er­streckt und auf der dem Langhaarschneidsystem abgewandten Bogen­seite in dem Endpunkt P₁ endet. In dem Endpunkt P₁ sind das Untermesser 16 und das Obermesser 17 aufgrund einer schneidfähigen Berührung noch scheraktiv wirksam bzw. können noch scheraktiv ein­gesetzt werden. Eine, den Endpunkt P₁ mit dem Berührungspunkt B₂ verbindende Verbindungslinie V schneidet die Gerade G₂. Der aus diesem Schnitt resultierende Schnittpunkt SP₁ dient mit dem Schnittpunkt SP der Geraden G₁ und G₂ als Bezugspunkt für den Abstand C, der ausschlaggebend ist für eine Anordnung der Schwenk­achse Z oberhalb und unterhalb der Geraden G₁.The intersection point SP represents the axis center for the pivot axis Z running in the longitudinal direction of a shaving head Z pivotably mounted on the housing 1 and serves as a reference point for the surrounding area within which the pivot axis Z can also be provided. The bow-shaped short hair cutting system K has a shear-active area which, starting from the point of contact B 1, extends in both directions on the bow shape and ends on the bow side facing away from the long hair cutting system in the end point P 1. In the end point P₁, the lower knife 16 and the upper knife 17 are still shear-active due to a cutable contact or can still be used shear-active. A, connecting the end point P₁ with the point of contact B₂ connecting line V intersects the straight line G₂. The resulting intersection SP₁ serves with the intersection SP of the straight line G₁ and G₂ as a reference point for the distance C, which is decisive for an arrangement of the pivot axis Z above and below the straight line G₁.

Das Langhaarschneidsystem L ist in einem vorgegebenen Winkel β zur Geraden G₁ in dem schwenkbaren Scherkopf 2 angeordnet. Die Größe des Winkels β liegt vorzugsweise in einem Bereich von 5° bis 25°. Diese Schrägstellung des Langhaarschneidsystems L zur Geraden G₁ und damit zum Kurzhaarschneidsystem K, bewirkt eine Bugwellenbildung der zu rasierenden Haut mit dem Ergebnis einer besonders guten Anlage der Hautfläche an beiden Schersystemen, die sonach in optimaler Weise gleichzeitig scheraktiv zum Einsatz ge­langen.The long hair cutting system L is arranged at a predetermined angle β to the straight line G₁ in the pivotable shaving head 2. The size of the angle β is preferably in a range from 5 ° to 25 °. This inclination of the long hair cutting system L to the straight line G 1 and thus to the short hair cutting system K, causes bow wave formation of the skin to be shaved, with the result that the skin area is particularly well placed on both shaving systems, which are therefore used in an optimal manner at the same time as a shear active.

In Fig. 3 wie auch in den Fig. 4 bis 6 sind die unter Fig. 2 be­schriebene Schwingbrücke 12 sowie der Antriebsstift 13, über die sowohl das Untermesser 16 als auch die Schneidklinge 23 in eine hin- und hergehende Schwingbewegung versetzt werden, durch einen U-förmigen Bügel und einen verstärkt gezeichneten Strich verein­facht dargestellt.In FIG. 3 as well as in FIGS. 4 to 6, the swing bridge 12 described under FIG. 2 and the drive pin 13, via which both the lower knife 16 and the cutting blade 23 are set into a reciprocating swinging movement, are by a U-shaped bracket and an increasingly drawn line are shown in simplified form.

Die Ausführungsform nach Fig. 4 zeigt einen um die Schwenkachse Z schwenkbar gelagerten Scherkopf 2, bestehend aus einem bogenförmi­gen Kurzhaarschneidsystem K und einem um den Winkel winklig zur Geraden G₁ verlaufenden Langhaarschneidsystem L mit nur einem Schneidbereich L₁, der entgegengesetzt zum Kurzhaarschneidsystem K vorgesehen ist. Die Schwenkachse Z verläuft durch den Schnitt­punkt SP der Geraden G₁ und G₂, wobei die Gerade G₂ die Ge­rade G₁ rechtwinklig und in der Mitte des Abstandes A, den die Berührungspunkte B₁ und B₂ zueinander haben, schneidet. Die Berührungspunkte B₁ und B₂ ergeben sich durch Anlage der Ge­raden G₁ an die äußere Kontur des bogenförmigen Kurzhaarschneid­systems K sowie des Langhaarschneidsystems L, wobei bei einer flächenartigen Berührung des Langhaarschneidsystems dirch die Ge­rade der vom Berührungspunkt B₁ am entferntest liegenden Berührungspunkt als Berührungspunkt B₂ maßgebend ist.The embodiment according to FIG. 4 shows a shaving head 2 pivotably mounted about the pivot axis Z, consisting of an arc-shaped short hair cutting system K and a long hair cutting system L running at an angle to the straight line G 1 with only one cutting area L 1, which is provided opposite to the short hair cutting system K. The pivot axis Z runs through the intersection SP of the straight lines G₁ and G₂, the straight line G₂ intersecting the straight line G₁ at right angles and in the middle of the distance A which the points of contact B₁ and B₂ have. The points of contact B₁ and B₂ result from the line G₁ bearing on the outer contour of the arcuate short hair cutting system K and the long hair cutting system L, with a flat contact of the long hair cutting system directly the straight line from the point of contact B₁ most distant point of contact is decisive as the point of contact B₂.

Bei dem Ausführungsbeispiel nach Fig. 5 befindet sich der Scher­kopf 2 in einer Mittelstellung seines Schwenkbereiches, wie bei­spielsweise aus Fig. 1 ersichtlich. Das mit nur einem Schneidbe­reich L₁ versehene Langhaarschneidsystem L ist in dem Scherkopf 2 gegenüber der äußeren Kontur des Kurzhaarschneidsystems K tiefer liegend angeordnet, wodurch die an die äußere Kontur des Kurz­haarschneidsystems K sowie an die äußere Kante des Langhaar­schneidsystems L gelegte Gerade G₁ die vertikale Achse VA in einem Winkel schneidet. Durch eine horizontale bzw. rechtwink­lige Ausrichtung der oberen Seitenfläche des Schneidkammes 22 zur vertikalen Achse VA verläuft dieser im Winkel β zur Geraden G₁ Die Winkel α und β weisen bei diesem Ausführungsbeispiel sonach eine identische Winkelgröße auf. Diese Identität ist jedoch nicht zwingend erforderlich, denn die obere Seitenfläche des Schneid­kammes 22 kann abweichend von der dargestellten Ausrichtung zur Geraden G₁ ausgerichtet sein und somit eine von der Winkel­größe α abweichende Winkelgröße einnehmen.In the exemplary embodiment according to FIG. 5, the shaving head 2 is in a central position of its pivoting range, as can be seen for example from FIG. 1. The provided with only one cutting area L 1 long hair cutting system L is arranged in the shaving head 2 deeper than the outer contour of the short hair cutting system K, whereby the line G 1 placed on the outer contour of the short hair cutting system K and on the outer edge of the long hair cutting system L the vertical axis VA in cuts an angle. By a horizontal or right-angled alignment of the upper side surface of the cutting comb 22 to the vertical axis VA, this runs at an angle β to the straight line G₁. The angles α and β in this embodiment therefore have an identical angular size. However, this identity is not absolutely necessary, because the upper side surface of the cutting comb 22 can be aligned differently from the orientation shown to the straight line G 1 and thus assume an angle size deviating from the angle size α.

Der Scherkopf 2 nach Fig. 5 ist um die Schwenkachse Z, die durch den Schnittpunkt SP der Geraden G₁ in der Mitte des Abstandes A rechtwinklig schneidenden Geraden G₂ verläuft, schwenkbar ge­lagert. Durch die dargestellte und beschriebene höhenversetzte Zu­ordnung des Langhaarschneidsystems L zum Kurzhaarschneidsystem K wird die Anlage beider Schneidsysteme des Scherkopfes 2 an der Hautfläche besonders begünstigt und eine Bugwellenbildung der zu rasierenden Haut bewirkt, mittels der eine wesentlich größere Hautfläche scheraktiv der Rasur zugeführt wird.5 is pivotally mounted about the pivot axis Z, which extends through the intersection SP of the straight line G 1 in the middle of the distance A, a straight line intersecting line G 2. The illustrated and described height-offset assignment of the long hair cutting system L to the short hair cutting system K particularly favors the installation of both cutting systems of the shaving head 2 on the skin surface and causes a bow wave formation on the skin to be shaved, by means of which a substantially larger skin area is sheared to the shave.

Bei dem Ausführungsbeispiel nach Fig. 6 ist der Scherkopf 2 um eine in Längsrichtung des Scherkopfes verlaufende Schwenkachse Z schwenkbar gelagert. Das bogenförmig gestaltete Kurzhaarschneid­system K ist zwischen zwei Langhaarschneidsystemen L₁ und L₂ gegenüber diesen herausragend vorgesehen. Die Schneidklinge 23 der Langhaarschneidsysteme L₁ und L₂ sowie das Untermesser 16 des Kurzhaarschneidsystems sind über die schematisch dargestellte Schwingbrücke 12 und den Antriebsstift 13 mit dem Antriebssystem des Trockenrasierapparates gekoppelt. Die Schwenkachse Z für den Scherkopf 2 verläuft bei diesem Ausführungsbeispiel durch den Schnittpunkt SP zweier Geraden G₃ und G₄, wobei G₃ eine an die äußere Kante des Langhaarschneidsystems L₁ sowie an die äußere Kontur des Kurzhaarschneidsystems K gelegte Gerade ist und G₄ eine an die äußere Kante des Langhaarschneidsystems L₂ sowie an die äußere Kontur des Kurzhaarschneidsystems K gelegte Gerade ist. Der Berührungspunkt der Geraden G₃ mit der äußeren Kante des Langhaarschneidsystems L₁ ist mit B₃ und der Berührungspunkt der Geraden G₄ mit der äußeren Kante des Langhaarschneidsystems L₂ mit B₂ bezeichnet. Die in Längsrichtung des Scherkopfes 2 durch den Schnittpunkt SP verlaufende Schwenkachse Z schneidet, wie aus der Darstellung ersichtlich, die vertikale Achse VA. Aufgrund der bei dem Ausführungsbeispiel nach Fig. 6 vorgesehenen symmetrischen Anordnung der beiden Langhaarschneidsysteme L₁ und L₂ zu dem zwischen diesen vorgesehenen Kurzhaarschneidsystem K ist gewährleistet, daß in jeder Schieberichtung des Scherkopfes 2 über die zu rasierende Haut jeweils eines der Langhaarschneidsysteme L₁ oder L₂ zusammen mit dem Kurzhaarschneidsystem K zum Einsatz gelangt.In the exemplary embodiment according to FIG. 6, the shaving head 2 is mounted so as to be pivotable about a pivot axis Z running in the longitudinal direction of the shaving head. The arcuate short hair cutting system K is provided between two long hair cutting systems L₁ and L₂ in relation to this outstanding. The cutting blade 23 of the long hair cutting systems L 1 and L 2 and the lower knife 16 of the short hair cutting system are coupled to the drive system of the dry shaver via the schematically illustrated swing bridge 12 and the drive pin 13. The pivot axis Z for the shaving head 2 runs in this embodiment through the intersection SP of two straight lines G₃ and G₄, where G₃ is a line placed on the outer edge of the long hair cutting system L₁ and on the outer contour of the short hair cutting system K and G₄ one on the outer edge of the Long hair cutting system L₂ as well as a straight line placed on the outer contour of the short hair cutting system K. The point of contact of the straight line G₃ with the outer edge of the long hair cutting system L₁ is B₃ and the point of contact of the straight line G₄ with the outer edge of the long hair cutting system L₂ is B₂. The pivot axis Z running through the intersection SP in the longitudinal direction of the shaving head 2 intersects, as can be seen from the illustration, the vertical axis VA. Due to the symmetrical arrangement of the two long hair cutting systems L 1 and L 2 provided for in the exemplary embodiment according to FIG between these intended short hair cutting system K it is ensured that one of the long hair cutting systems L 1 or L 2 together with the short hair cutting system K is used in each sliding direction of the shaving head 2 via the skin to be shaved.

Die Schwenkachse Z für den schwenkbaren Scherkopf 2 kann unter Sicherstellung, daß bei normal üblichen Anstellwinkeln des Rasier­apparatengehäuses zur Hautfläche die gesamte, für eine Rasuer nutz­bare Scherfläche an der Hautfläche zur Analge kommt und daß bei wechselnden Schieberichtungen des Scherkopfes an der Hautfläche ein Wegkippen der Scherfläche bzw. eines Teils der nutzbaren Scherfläche von der Hautfläche verhindert ist, innerhalb eines Um­gebungsbereiches um den Schnittpunkt SP vorgesehen werden. Es ver­steht sich von selbst, daß eine Anordnung der Schwenkachse Z im Umgebungsbereich um den Schnittpunkt SP unter praxisgerechten Ge­sichtspunkten durchzuführen ist. Die Grenzen eines zulässigen Ab­standes der Schwenkachse Z vom Schnittpunkt SP können aufgrund der zu berücksichtigenden Einflußgrößen, wie z.B. Bogenform des Kurz­haarschneiders K, Winkelstellung β des oder der Langhaarschneid­systeme L zur Geraden G₁, Abstand C der Schnittpunkte SP und SP₁ der Geraden G₂ mit der Geraden G₁ und der Verbindungs­linie V, Reibung von Kurzhaar- und Langhaarschneidsystem an der Haut und Bereich der auftretenden Andruckkräfte des Rasierappa­rates an der Hautfläche für die jeweilige Ausführungsform, nur durch praktische Versuche ermittelt werden. Ausgehend von der Ge­raden G₁ kann sich der Umgebungsbereich in etwa bis zur Mitte des von dem Schnittpunkt SP der Geraden G₁ und G₂ bis zum Schnittpunkt SP₁ der Geraden G₂ mit der Verbindunglinie V ge­gebenen Abstandes C unterhalb der Geraden G₁ sowie in etwa bis zu dem Zehnfachen des zuvor dargelegten Abstandes C oberhalb der Geraden G₁ erstrecken. Eine Verlagerung der Schwenkachse Z in einem Abstand x zur Geraden G₂ sowohl in Richtung des Berüh­rungspunktes B₂ auf der Geraden G₁ oder unterhalb oder ober­halb der Geraden G₁ ist ebenfalls durchführbar unter Berücksich­tigung zuvor genannter Einflußgrößen.The pivot axis Z for the pivotable shaving head 2 can ensure that at normal angles of incidence of the razor housing to the skin surface, the entire shaving surface that can be used for a shave comes to an end on the skin surface and that the shaving surface on the skin surface tilts away with changing shifting directions of the shaving head a part of the usable shear surface is prevented by the skin surface, can be provided within a surrounding area around the intersection SP. It goes without saying that the pivot axis Z must be arranged in the area around the intersection SP from a practical point of view. The limits of a permissible distance of the pivot axis Z from the intersection SP can be due to the influencing factors to be taken into account, such as arc shape of the short hair trimmer K, angular position β of the or the long hair cutting systems L to the straight line G 1, distance C of the intersections SP and SP 1 of the straight line G 2 with the straight line G 1 and the connecting line V, friction of the short hair and long hair cutting system on the skin and area of the pressure forces of the razor on the skin surface for the particular embodiment can only be determined by practical tests. Starting from the straight line G₁, the surrounding area can be approximately to the middle of the given distance C from the intersection SP of the straight line G₁ and G₂ to the intersection SP₁ of the straight line G₂ with the connecting line V below the straight line G₁ and approximately up to ten times that previously described distance C above the straight line G₁. A shift of the pivot axis Z in a distance x to the straight line G₂ both in the direction of the point of contact B₂ on the straight line G₁ or below or above the straight line G₁ is also feasible taking into account the aforementioned influencing variables.

Ein praktisches Ausführungsbeispiel mit einer von der Geraden G₂ und somit vom Schnittpunkt SP in Richtung des Berührungspunktes B₁ auf der Geraden G₁ verlagerten Schwenkachse Z für den Scherkopf 2 ist in Fig. 7 dargestellt und wird im folgenden näher erläutert. Fig. 7 zeigt einen Querschnitt durch den Scherkopf 2 und den oberen Teil des Gehäuses 1 des Rasierapparates nach den Figuren 1 und 2.A practical embodiment with one of the straight line G₂ and thus from the intersection SP in the direction of the contact point B₁ on the straight line G₁ shifted pivot axis Z for the shaving head 2 is shown in Fig. 7 and will be explained in more detail below. FIG. 7 shows a cross section through the shaving head 2 and the upper part of the housing 1 of the shaving apparatus according to FIGS. 1 and 2.

Auf den sich in Längsrichtung des Scherkopfes 2 erstreckenden Stegen 25 des Scherkopfgehäuses ist ein Wechselrahmen 26 aufge­setzt und mittels Federn 27 abnehmbar gehalten. In dem Wechsel­rahmen 26 ist ein aus einer Scherfolie bestehendes Obermesser 17 gewölbt eingespannt. Parallel zu dem Obermesser 17 verlaufend ist ein mit zwei Schneidbereichen L₁ und L₂ versehenes Langhaar­schneidsystem L als Bestandteil des Wechselrahmens in diesem ange­ordnet. Langhaarschneidsystem L ist mit einem an der Schwingbrücke 12 angeformten Kupplungselement 14 gekoppelt. Das Langhaarschneid­system L ist als beidseitig schneidendes Schneidsystem L₁ und L₂ ausgebildet und in einem Winkel β zur Geraden G₁ ausge­richtet. Das aus einem bogenförmig gestalteten Messerblock be­stehende Untermesser 16 ist mittels eines Kupplungselementes 15 ebenfalls mit der Schwingbrücke 12 gekoppelt, die von einem, aus dem Gehäuse 1 herausragenden Antriebsstift 13 in Schwingbewegung versetzt wird und die Schwingbewegung mittels der Kupplungs­elemente 14 und 15 auf das Untermesser 16 und die Schneidklinge 23 der beiden Schneidsysteme überträgt.An interchangeable frame 26 is placed on the webs 25 of the shaving head housing which extend in the longitudinal direction of the shaving head 2 and is held detachably by means of springs 27. In the interchangeable frame 26, an upper knife 17 consisting of a shear foil is arched. Running parallel to the upper knife 17, a long-hair cutting system L provided with two cutting areas L 1 and L 2 is arranged as part of the change frame in this. Long hair cutting system L is coupled to a coupling element 14 formed on the oscillating bridge 12. The long hair cutting system L is designed as a cutting system L 1 and L 2 that cuts on both sides and is oriented at an angle β to the straight line G 1. The lower knife 16, which consists of an arcuately shaped knife block, is also coupled by means of a coupling element 15 to the oscillating bridge 12, which is set in oscillating motion by a drive pin 13 protruding from the housing 1 and the oscillating movement by means of the coupling elements 14 and 15 to the lower knife 16 and the cutting blade 23 transmits the two cutting systems.

Mit A ist der Abstand der äußersten Berührungspunkte B₁ und B₂ der das Kurzhaarschneidsystem K und das Langhaarschneidsystem L berührenden Geraden G₁ und mit G₂ eine die Gerade G₁ in der Mitte des Abstandes A rechtwinklig schneidende Gerade dargestellt. Der Schnittpunkt der Geraden G₁ und G₂ ist mit SP bezeichnet. Die Schwenkachse Z für den Scherkopf 2 ist bei diesem Ausführungs­beispiel in einem Abstand X zur Geraden G₂ bzw. zum Schnittpunkt SP, und zwar in Richtung des Berührungspunktes B₁ vorgesehen, wobei die Schwenkachse Z die Gerade G₁ schneidet. Wie unter Fig. 2 beschrieben und in Fig. 2 dargestellt, ist die Schwenkachse Z identisch mit den Mittenachsen der Gelenkbolzen 18 und 19, mittels denen der Scherkopf 2 schwenkbar in den Lagerbohrungen 20 und 21 der Tragarme 4 und 5 gelagert ist. In Fig. 7 ist die durch den Scherkopf 2 gehende Symmetrieachse als vertikale Achse VA darge­stellt. Der Abstand x um den die Schwenkachse Z von der Geraden G₂ in Richtung des Berührungspunktes B₁ verlagert ist, ist identisch mit dem Abstand der vertikalen Achse VA zur Geraden G₂ auf der Geraden G₁. Die Schwenkachse Z verläuft sonach durch den Schnittpunkt der Geraden G₁ mit der vertikalen Achse VA, wodurch eine besonders ausgeglichene Schwenkbarkeit des Scherkopfes 2 er- zielt wird. Demzufolge ist, ausgehend von der Geraden G₂, eine Verlagerung der Schwenkachse Z in Richtung der vertikalen Achse VA eines Scherkopfes 2 bevorzugt anzuwenden. 1 Gehäuse

With A the distance of the outermost points of contact B₁ and B₂ of the short hair cutting system K and the long hair cutting system L touching straight lines G₁ and with G₂ a straight line G₁ in the middle of the distance A intersecting straight line is shown. The intersection of the straight lines G₁ and G₂ is designated SP. The pivot axis Z for the shaving head 2 is provided in this embodiment at a distance X to the straight line G₂ or to the intersection SP, in the direction of the point of contact B₁, the pivot axis Z intersecting the straight line G₁. As described under Fig. 2 and shown in Fig. 2, the pivot axis Z is identical to the center axes of the hinge pins 18 and 19, by means of which the shaving head 2 is pivotally mounted in the bearing bores 20 and 21 of the support arms 4 and 5. 7 shows the axis of symmetry passing through the shaving head 2 as the vertical axis VA. The distance x about which the pivot axis Z is shifted from the straight line G₂ in the direction of the contact point B₁ is identical to the distance from the vertical axis VA to the straight line G₂ on the straight line G₁. The pivot axis Z thus runs through the intersection of the straight line G 1 with the vertical axis VA, whereby a particularly balanced pivotability of the shaving head 2 is achieved. Accordingly, starting from the straight line G₂, a displacement of the pivot axis Z in the direction of the vertical axis VA of a shaving head 2 is preferably to be used. 1 housing
