Description

Die Erfindung bezieht sich auf einen Trockenrasierapparat mit wenigstens einem in einem schwenkbaren, an seinen Seiten geschlossenen Kopfrahmen angeordneten Scherblatt, mit welchem in Längsrichtung der Scherblätter oszillierende Messer zusammenwirken, wobei der Scherkopf lösbar mit dem den Antrieb aufweisenden Basisteil verbunden ist.The invention relates to a dry shaver at least one in a swiveling, closed on its sides Head frame arranged shaving blade, with which in Oscillating knives interact in the longitudinal direction of the shear blades, the shaving head being releasable with that having the drive Base part is connected.

Trockenrasierapparate sind in unterschiedlicher Bauform bekannt. Neben Trockenrasierapparaten mit rotierenden Messern, bei welchen die relativ kleinen Durchmesser aufweisenden Scherblätter in einem Kopfrahmen federnd angeordnet sind, sind vor allen Dingen Trockenrasierapparate bekannt, bei welchen in einem Basisteil ein Antriebsmotor angeordnet ist, welcher mit einem oder mehreren Klingenblöcken bzw. Lamellenträgern gekoppelt ist, wobei die Lamellen bzw. Klingen der Klingenblöcke bzw. Lamellenträger zu oszillierender Bewegung angetrieben sind. Die Oszillationsrichtung derartiger Klingenblöcke erstreckt sich hiebei in Richtung der Achse der Hüllkurve der Lamellen, wobei diese Lamellen bzw. Klingen mit Scherblättern zusammen wirken, welche selbst wiederum gewölbt ausgebildet sein können. Die Krümmung der Scherblätter folgt hierbei der Hüllkurve bzw. der Hüllfläche der Lamellen bzw. Messerkanten, wobei die Länge eines derartigen Scherblattes in Achsrichtung der Krümmung der Hüllfläche gemessen ist. Es können eine Mehrzahl derartiger Klingenblöcke parallel zueinander zu gleichsinniger oder gegensinniger oszillierender Bewegung angetrieben sein, wobei das Scherblatt eine entsprechende Mehrzahl von gekrümmten Flächen, welche mit den Hüllflächen der Lamellen zusammenwirken, aufweist. Das Scherblatt ist in aller Regel in einem Kopfrahmen angeordnet und kann gemeinsam mit dem Kopfrahmen für die Reinigung abgenommen werden. Zu diesem Zweck wird der Kopfrahmen vom Basisteil gelöst, wobei in aller Regel zumindest das Scherblatt gemeinsam mit dem Kopfrahmen vom Basisteil getrennt wird. In der Folge können die oszillierenden Messer der Klingenblöcke und das Scherblatt gesondert gereinigt werden, worauf durch einfaches Zusammenstecken der Betriebszustand wieder hergestellt werden kann. Neben derartigen Ausbildungen sind auch Ausbildungen bekannt, bei welchen auch die Klingenblöcke im Kopfrahmen gelagert sind und gemeinsam mit dem Kopfrahmen abgenommen werden. Bei derartigen Ausbildungen gestaltet sich die Reinigung etwas aufwendiger.Dry shavers are known in different designs. In addition to dry shavers with rotating knives, which the relatively small diameter shear blades are resiliently arranged in a head frame, are above all Dry shavers known, in which in a base part a drive motor is arranged, which with or several blade blocks or lamellar carriers is coupled, wherein the blades or blades of the blade blocks or blade carriers are driven to oscillate movement. The direction of oscillation such blocks of blades extend here in the direction of the axis of the envelope of the slats, this Slats or blades work together with shaving blades, which themselves can be curved. The curvature the cutters follow the envelope or the envelope surface the slats or knife edges, the length of such Blade measured in the axial direction of the curvature of the envelope surface is. A plurality of such blade blocks can be parallel to oscillate in the same direction or in opposite directions Movement be driven, the shear blade a corresponding plurality of curved surfaces, which with the Coating surfaces of the slats interact. The foil is usually arranged in a head frame and can can be removed together with the head frame for cleaning. For this purpose, the head frame is detached from the base part, as a rule, at least the shaving blade together with the Head frame is separated from the base part. As a result, the oscillating knife of the blade blocks and the shear blade separately can be cleaned, then by simply plugging them together the operating state can be restored. In addition to such Apprenticeships are also known, in which also the blade blocks are stored in the head frame and together can be removed with the head frame. With such training cleaning is a little more complex.

Ein Trockenradierapparat nach dem Oberbegriff von Anspruch 1 ist bekannt aus dem Dokument GB-A-2 266 070.A dry eraser according to the preamble of claim 1 is known from document GB-A-2 266 070.

Die bekannten Ausbildungen bzw. Anordnungen von Scherblättern und Klingenblöcken erlaubt ein gewisses Maß an elastischer Nachgiebigkeit. Sowohl das relativ dünnwandige Scherblatt, welches elastisch verformbar ist, als auch der Klingenblock, welcher federnd mit dem Antrieb verbunden ist, können bei Druckbeanspruchung ausweichen, wobei diese Ausweichbewegung der besseren Anpassung an die zu rasierende Haut dient. Derartige Ausweichbewegungen sind allerdings durch die Begrenzungskanten des Kopfrahmens begrenzt. Um eine bessere Anpassung an die Kontur der Haut zu ermöglichen, ist es bekannt, den Kopfrahmen mitsamt dem Scherblatt und den oszillierenden Messern, schwenkbar mit den Basisteil zu verbinden, wobei bei den bekannten Ausbildungen eine Schwenkachse vorgesehen ist, welche im wesentlichen parallel zur Achse der Hüllfläche der Lamellen bzw. zur Achse der Krümmung des Scherblattes verläuft. Eine derartige Schwenkbarkeit dient hiebei in erster Linie bei mehreren parallel zueinander oszillierend angetriebenen Klingenblöcken dazu, daß eine Mehrzahl derartiger Klingenblöcke und Scherblättern gleichzeitig in eine Arbeitsposition gelangt. Je nach Länge der Scherblätter ergibt sich jedoch aufgrund der unterschiedlichen Kontur der Haut über die Länge des Scherblattes ein unterschiedliches Anpressverhalten, welchem der Benützer eines derartigen Trockenrasierapparates immer durch geeignetes Orientieren des Basisteiles und damit der Scherblätter kompensieren muß. Im Extremfall ist nur ein Teil der Länge der Scherblätter in einem wirksamen Eingriff mit der zu rasierenden Haut, sodaß die Zeit, welche für eine glatte Rasur benötigt wird, wesentlich größer wird, da entsprechend mehrmalige Korrekturen erforderlich sind.The known designs or arrangements of shear blades and blade blocks allows some degree of resilience. Both the relatively thin-walled foil, which is elastically deformable, as is the blade block, which is resiliently connected to the drive, under pressure evade, this evasive movement of better adjustment to the skin to be shaved. Such evasive movements are due to the boundary edges of the head frame limited. To better adapt to the contour of the It is known to enable the skin, together with the head frame Blade and the oscillating knives, swiveling with the To connect the base part, a in the known designs Swivel axis is provided, which is substantially parallel to the axis of the envelope surface of the slats or to the axis of the curvature of the cutter blade runs. Such swiveling serves primarily with several parallel to each other oscillating blade blocks that a plurality such blades and shaving blades in simultaneously got a working position. Depending on the length of the shaving blades however due to the different contour of the skin a different contact behavior over the length of the shear blade, which the user of such a dry shaver always by appropriately orienting the base part and so that the shear blades must compensate. In an extreme case it is only part of the length of the shear blades in one effective engagement with the skin to be shaved, so that the time it takes for one a smooth shave is required, it becomes much larger because it is corresponding repeated corrections are required.

Die Erfindung zielt nun darauf ab, den Anpressdruck von Scherblättern und oszillierenden Messern an unterschiedliche Konturen der Haut ohne häufige Korrektur der Winkelstellung des Basisteiles relativ zur Haut zu vergleichmäßigen und eine Ausbildung zu schaffen, mit welcher ohne erhöhte Aufmerksamkeit des Verwenders des Rasierapparates eine optimale Anpassung des Schneidkopfes an die Kontur der Haut ermöglicht wird, ohne daß dadurch der Reinigungsaufwand erhöht wird. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung im wesentlichen darin, daß der Kopfrahmen zweiteilig ausgebildet ist, wobei der das oder die Scherblatt(er) tragende äußere Kopfteil um eine sich quer zur Oszillationsrichtung der Messer erstreckende, etwa mittige Schwenkachse mit dem am Basisteil lösbar festgelegten Teil des Kopfrahmens verbunden ist. Dadurch, das der an seinen Seiten geschlossene Kopfrahmen zweiteilig ausgebildet ist und der jeweils äußere Teil des Kopfrahmens schwenkbar an dem am Basisteil des Rasierapparates lösbar festgelegten ersten Teil des Kopfrahmens angelenkt ist, wird eine geschlossene Ausbildung geschafft, welche als Einheit vom Basisteil abnehmbar ist und leicht gereinigt werden kann. Gleichzeitig wird durch die Verschwenkbarkeit des äußeren Teiles des Kopfrahmens sicher gestellt, daß eine entsprechend große Verschwenkbarkeit möglich ist, ohne daß die Haut mit den Rändern des Kopfrahmens kollidiert und auf diese Weise die Verschwenkung des Scherblatters und der Lamellen behindert. Durch Abnahme des gesamten zweiteiligen Kopfrahmens kann somit zumindest das Scherblatt vom Basisteil und vom Lamellenblock getrennt werden, sodaß eine einfache Reinigung ermöglicht wird. Bei der Verschwenkung des äußeren Kopfteiles werden immer gleichzeitig auch die Außenkanten des äußeren Kopfteiles mitverschwenkt, sodaß die Verschwenkung durch den Kopfrahmen in keiner Weise beeinträchtigt wird und ein entsprechend großer Schwenkwinkel zur Verfügung steht.The invention now aims to reduce the contact pressure of shear blades and oscillating knives on different contours of the skin without frequent correction of the angular position of the base part to even out relative to the skin and training to create with which without increased user attention the shaver optimal adjustment of the cutting head to the contour of the skin is made possible without this the cleaning effort is increased. To solve this task the training according to the invention essentially consists in that the head frame is formed in two parts, the or the outer head part carrying the shaving blade (s) around itself extending transversely to the direction of oscillation of the knives, approximately central pivot axis with the detachably fixed on the base part Part of the head frame is connected. Because of that at his Sides closed head frame is formed in two parts and the respective outer part of the head frame pivotable on the Base part of the razor detachably fixed first part the head frame is articulated, a closed training managed, which is removable as a unit from the base part and can be easily cleaned. At the same time due to the pivotability the outer part of the head frame that a correspondingly large pivotability is possible without the skin colliding with the edges of the head frame and in this way the pivoting of the cutter blade and the slats hindered. By removing the entire two-part Head frame can thus at least the shaving blade from the base part and be separated from the slat block, so that a simple Cleaning is made possible. When pivoting the outer The headboard is always the outer edges of the pivoted outer head part, so that the pivoting through the head frame is not affected in any way and accordingly large swivel angle is available.

Die Abdichtung der beiden Teile des Kopfrahmens relativ zueinander kann in konventioneller Weise und besonders einfach erfolgen, wobei bevorzugt die Ausbildung so getroffen ist, daß der schwenkbare äußere Kopfteil über Dichtflächen oder Dichtmanschetten mit dem am Basisteil lösbar festgelegten Kopfteil verbunden ist. Während eine Verschwenkbarkeit des Scherblattes im Kopfrahmen, je nach Schwenkstellung, immer mehr oder minder große Durchtrittsöffnungen für geschnittene Barthaare und damit ein hohes Maß an Verschmutzungsgefahr mit sich trägt, führt die geschlossene Ausbildung mit dem schwenkbaren äußeren Kopfteil, welcher über Dichtflächen oder Dichtmanschetten mit den am Basisteil lösbar festgelegten Kopfteil verbunden ist, zu einer sicheren Aufnahme der geschnittenen Barthaare im Inneren des Kopfrahmens, sodaß diese nach Abnahme des gesamten Kopfrahmens leicht entfernt und die Scherblätter und die Messer leicht gereinigt werden können.The sealing of the two parts of the head frame relative to each other can be done in a conventional and particularly simple manner, the training is preferably such that the swiveling outer head part over sealing surfaces or sealing sleeves connected to the head part releasably attached to the base part is. While a pivoting of the shaving blade in the Head frame, depending on the swivel position, more or less large openings for cut whiskers and thus carries a high degree of contamination risk closed training with the swiveling outer head part, which via sealing surfaces or sealing sleeves with the am Base part releasably fixed head part is connected to a secure absorption of the cut whiskers inside the Head frame, so that this after removal of the entire head frame easily removed and the shaving blades and knives easily cleaned can be.

Mit Vorteil ist die Ausbildung erfindungsgemäß so getroffen, daß die Schwenkachse eines die Messer tragenden Blockes und die Schwenkachse des äußeren Kopfteiles in einer Längsmittelebene des Basisteiles liegen. Bei einer derartigen Anordnung der Schwenkachse und insbesondere bei einer Anordnung, bei welcher die Schwenkachse eines die Messer tragenden Blockes und die Schwenkachse des äußeren Kopfteiles miteinander fluchten, wird die federnde Verbindung zwischen dem Messerblock und dem Antrieb im wesentlichen genauso beansprucht, wie bei konventionellen Ausführungen, wobei zusätzliche Kräfte vermieden werden.The training according to the invention is advantageously made such that the pivot axis of a block carrying the knives and the Pivot axis of the outer head part in a longitudinal center plane of the base part. With such an arrangement the Swivel axis and in particular in an arrangement in which the pivot axis of a block carrying the knives and the The swivel axis of the outer head section is aligned with one another the resilient connection between the knife block and the drive essentially as stressed as conventional ones Executions, whereby additional forces are avoided.

Die relativ große Schwenkbarkeit des äußeren Kopfteiles relativ zu dem am Basisteil lösbar festgelegten Kopfteiles kann in einfacher Weise begrenzt werden, wobei mit Vorzug die Ausbildung so getroffen ist, daß die Schwenkbarkeit des schwenkbaren äußeren Kopfteiles über Anschläge an dem am Basisteil lösbar festgelegten Kopfteil begrenzt ist.The relatively large pivotability of the outer head part relative to the head part releasably fixed to the base part can be done in a simple manner Ways are limited, with training preferred is taken that the pivotability of the pivotable outer Head part via stops on the detachably fixed on the base part Headboard is limited.

Die Rückstellung des schwenkbaren äußeren Teiles des Kopfrahmens in eine zur Oberkante des Basisteiles im wesentlichen parallele Position kann durch zwischengeschaltete Federn erfolgen. In besonders einfacher Weise kann die Ausbildung hiebei so getroffen sein, daß die Dichtmanschette als Feder ausgebildet ist.The provision of the pivoting outer part of the head frame in a substantially parallel to the upper edge of the base part Position can be done by interposed springs. Especially The training can be easily done in this way be that the sealing sleeve is designed as a spring.

Die Erfindung wird nachfolgend anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig.1 eine Vorderansicht einer ersten Ausführungsform des erfindungsgemäßen Trockenrasierapparates mit einem schwenkbaren Kopfteil, Fig.2 den Trockenrasierapparat gemäß Fig.1 mit einem schwenkbaren Kopfteil in einer ersten Schwenklage, Fig.3 den Trockenrasierapparat gemäß Fig.1 teilweise im Schnitt, Fig.4 den Trockenrasierapparat gemäß Fig.2 teilweise im Schnitt, Fig.5 eine Vorderansicht einer zweiten Ausführungsform des erfindungsgemäßen Trockenrasierapparates mit schwenkbarem Kopfteil, Fig.6 den Trockenrasierapparat gemäß Fig.5 mit einen schwenkbaren Kopfteil in einer Schwenklage, Fig.7 den Trockenrasierapparat gemäß Fig.5 teilweise im Schnitt und Fig.8 den Trockenrasierapparat gemäß Fig.6 teilweise im Schnitt.The invention is described schematically below with reference to the drawing illustrated embodiments explained in more detail.

In Fig.1 ist ein Trockenrasierapparat 1 dargestellt, welcher einen Basisteil 2 sowie einen Kopfrahmen 3 aufweist. Der zweiteilig ausgebildete Kopfrahmen 3 besteht aus einem äußeren Kopfteil 4, in welchem die Scherblätter 5 angeordnet sind, sowie aus einem Kopfteil 6, welcher am Basisteil 2 lösbar festgelegt ist. Dabei wirken die im äußeren Kopfteil angeordneten Scherblätter 5 mit nicht näher dargestellten Klingen bzw. Lamellen zusammen, wobei die Klingen bzw. Lamellen in Richtung des Doppelpfeiles 7 oszillieren. Der äußere Kopfteil 4 ist mit dem am Basisteil 2 lösbar festgelegten Kopfteil 6 um eine sich quer zur Oszillationsrichtung 7 der Klingen bzw. Lamellen erstreckende Schwenkachse 8 schwenkbar verbunden. Es wird somit eine Verschwenkbarkeit des die Scherblätter 5 aufweisenden äußeren Kopfteiles 4 in Richtung des Doppelpfeiles 9 sichergestellt, womit eine optimale Anpassung des die Scherblätter 5 aufweisenden äußeren Kopfteiles 4 an die Kontur der Haut ermöglicht wird. Am äußeren Kopfteil 4 sind dabei Dichtflächen 10 vorgesehen, welche mit dem am Basisteil 2 lösbar festgelegten Kopfteil 6 zusammenwirken, sodaß eine sichere Aufnahme der geschnittenen Barthaare im Inneren des Kopfrahmens ohne Verschmutzungsgefahr des Schneidkopfes gewährleistet ist.In Figure 1, a dry shaver 1 is shown, which has a base part 2 and a head frame 3. The two-part trained head frame 3 consists of an outer head part 4, in which the shear blades 5 are arranged, and from a head part 6, which is releasably attached to the base part 2. The shear blades 5 arranged in the outer head part act here with blades or lamellas not shown in detail, the blades or lamellae in the direction of the double arrow 7 oscillate. The outer head part 4 is with that on the base part 2 detachably fixed head part 6 to a transverse to the direction of oscillation 7 of the blades or slats extending pivot axis 8 pivotally connected. It thus becomes pivotable of the outer blades 4 having the shear blades 5 in Direction of the double arrow 9 ensured, making an optimal Adjustment of the outer head part having the shaving blades 5 4 to the contour of the skin is made possible. On the outer head part 4 sealing surfaces 10 are provided, which with the on the base part 2 releasably fixed head part 6 cooperate so that one secure absorption of the cut whiskers inside the Head frame guaranteed without risk of contamination of the cutting head is.

Fig.2 zeigt den in Fig.1 dargestellten Trockenrasierapparat 1, bei welchem der äußere Kopfteil 4, in welchem die Scherblätter 5 angeordnet sind, um die Schwenkachse 8 in eine Schwenklage verschwenkt wurde. Die mit dem Kopfteil 6 zusammenwirkenden Dichtflächen 10 gewährleisten dabei auch in der Verschwenklage eine sichere Abdichtung des Kopfrahmens 3.2 shows the dry shaving apparatus 1 shown in FIG. 1, in which the outer head part 4, in which the shear blades 5 are arranged, pivoted about the pivot axis 8 in a pivot position has been. The sealing surfaces interacting with the head part 6 10 ensure a in the swivel position secure sealing of the head frame 3.

In Fig.3 ist der in Fig.1 dargestellte Trockenrasierapparat teilweise im Schnitt dargestellt. Die Bezugszeichen wurden dabei für gleiche Teile beibehalten. Der mit einem Motor 12 zusammenwirkende Antrieb 11 ist dabei im Basisteil 2 angeordnet und versetzt die Lamellenträger 13 in Richtung des Doppelpfeiles 7 in oszillierende Bewegung. Die Hüllkurve der Klingen bzw. Lamellen ist dabei durch die strichpunktierte Linie 14 angedeutet. Die Schwenkachse 15 des Lamellenträgers 13 liegt dabei, ebenso wie die Schwenkachse 8 des äußeren Kopfteiles in der durch die strichpunktierte Linie 16 angedeutete Längsmittelebene des Basisteiles 2. Für die Rückstellung des um die Schwenkachse 8 schwenkbaren äußeren Kopfteiles 4 des Kopfrahmens 3 in eine zur Oberkante des Basisteiles 2 im wesentlichen parallele Position, sind Federn 17 vorgesehen, welche zwischen dem äußeren Kopfteil 4 und dem Kopfteil 6 abgestützt sind. Um die Schwenkbarkeit des äußeren Kopfteiles 4 relativ zu dem mit dem Basisteil 2 lösbar verbundenen Kopfteil 6 zu begrenzen, sind am äußeren Kopfteil 4 Anschläge 18 vorgesehen.In Figure 3 is the dry shaver shown in Figure 1 partially shown in section. The reference numerals were used keep for same parts. The one interacting with a motor 12 Drive 11 is arranged in the base part 2 and offset the disk carrier 13 in the direction of the double arrow 7 in oscillating movement. The envelope of the blades or lamellas is indicated by the dash-dotted line 14. The The pivot axis 15 of the disk carrier 13 lies here, as well the pivot axis 8 of the outer head part in the by dash-dotted line 16 indicated longitudinal median plane of the Base part 2. For resetting the about the pivot axis 8 pivotable outer head part 4 of the head frame 3 in a Upper edge of the base part 2 in a substantially parallel position, springs 17 are provided, which between the outer head part 4 and the head part 6 are supported. To the pivoting of the outer head part 4 releasable relative to that with the base part 2 to limit the connected head part 6 are on the outer head part 4 Stops 18 provided.

Fig.4 zeigt den Trockenrasierapparat gemäß Fig.2 teilweise im Schnitt, wobei der schwenkbare Kopfteil 4 um die Schwenkachse 8 bis zum Anschlag 18 verschwenkt wurde.
