Abstract

The electric dry razor has a survable cutting head (2) reciprocated via a drive parallel to its longitudinal axis, both th drive and the cutting head (2) having a crank element (5, 7) coupled together via a crank rod (6). Pref. the body (1) of the razor and the cutting head (2) are coupled via a linkage enclosed by a bellows (3a) for preventing the ingress of dirt. The razor body (1) contains an electric motor driving one crank element (5), the second crank element (7) rotated through a lesser angle for each full rotation of the first crank element (5). ADVANTAGE - Allows efficient rapid share.

Description

Die Erfindung betrifft einen elektrisch betriebenen Rasierapparat mit beweglichem Scherkopf.The invention relates to an electrically operated Shaver with movable shaving head.

Elektrisch betriebene Rasierapparate mit beweglichem Scherkopf sind bekannt. Hierbei erfolgt die Bewegung des Scherkopfes parallel zur Längsachse des Scherkopfes entsprechend der Bewegungsrichtung des Rasierapparates auf der Haut. Allerdings ist bei dieser Ausführungsform eines Rasierers keine Verbesserung der Rasurqualität gegenüber herkömmlichen Apparaten festzustellen. Electric shavers with a movable shaving head are known. Here the shaving head moves parallel to the longitudinal axis of the shaving head according to the Direction of movement of the razor on the skin. However, this embodiment is a razor no improvement in shaving quality compared to conventional ones Determine apparatus.  

Nach wie vor muß der Rasierer zur Erzielung einer guten Rasur­ qualität mehrfach über ein und dieselbe Stelle im Gesicht geführt werden, um sicherzustellen, daß sämtliche Barthaare von dem Rasierer erfaßt werden können. Das heißt der Zeitaufwand zur Erzielung einer guten Rasur ist erheblich.The shaver still needs to get a good shave quality multiple times over the same spot on the face be made to ensure that all whiskers can be detected by the razor. That is called It takes a lot of time to get a good shave.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Rasierer zu schaffen, mit dem der Zeitaufwand für eine qualitativ hochwertige Rasur vermindert werden kann.The invention is therefore based on the object To create a razor that takes the time spent on a high quality shaving can be reduced.

Dies wird erfindungsgemäß dadurch erreicht, daß der Scherkopf mittels eines Antriebes eine Pendelbewegung parallel zur Längsachse des Scherkopfes durchführt, d. h. um die Drehachse des Scherkopfes pendelt. Durch die Pendelbewegung des Scherkopfes parallel zu seiner Längsachse wird eine erheblich höhere Rasierleistung erreicht, da durch diese Pendelbewegung die zu rasierende Oberfläche mehrfach durch den Scherkopf erfaßt wird, ohne daß der Apparat selbst mehrfach über die entsprechende Gesichtspartie geführt werden muß.This is achieved according to the invention in that the shaving head a pendulum movement parallel to the by means of a drive Performs longitudinal axis of the shaving head, d. H. around the axis of rotation of the shaving head swings. By the pendulum movement of the Shaving head parallel to its longitudinal axis becomes significant achieved higher shaving performance because of this pendulum movement the surface to be shaved several times through the shaving head is detected without the apparatus itself repeatedly using the appropriate part of the face must be performed.

Zur Erzielung einer Pendelbewegung parallel zu seiner Längsachse weist der Scherkopf einen Exenterantrieb auf. Der Exenterantrieb setzt sich hierbei aus einem jeweils am Scherkopf und am Antrieb angeordneten Kurbelelement zusammen, wobei die beiden Kurbelelemente durch eine Kurbelstange miteinander verbunden sind. Hierbei weist das an dem Scherkopf angeordnete Kurbelelement eine größere Auslenkung auf, als das am Antrieb angeordnete Kurbelelement. Hierdurch wird erreicht, daß bei Rotation des am Antrieb angeordneten Kurbelelementes das am Scherkopf angeordnete Kurbelelement sich jeweils nur um eine bestimmte Gradzahl parallel zur Längsachse verschwenkt. Als Antrieb kann ein elektro­ motorischer, vorzugweise steuerbarer Antrieb vorgesehen sein.To achieve a pendulum movement parallel to it The shaving head has an eccentric drive along the longitudinal axis. The Eccentric drive consists of one each Shaving head and crank element arranged on the drive, where the two crank elements by a crank rod are interconnected. This indicates that Shaving head arranged crank element a greater deflection on as the crank element arranged on the drive. Hereby is achieved that the rotation of the arranged on the drive Crank element, the crank element arranged on the shaving head each time only by a certain number of degrees parallel to Longitudinal pivoted. An electric Motorized, preferably controllable drive can be provided.

In der Zeichnung ist eine beispielsweise Ausführungsform eines Rasierapparates mit motorisch angetriebenen beweglichem Scherkopf dargestellt.In the drawing is an example embodiment a razor with motor-driven movable Shaving head shown.

Der Rasierapparat besteht hierbei aus dem Körper 1 und dem Scherkopf 2. Der Körper 1 und der Scherkopf 2 sind durch einen gelenkig ausgebildeten Übergang 3 miteinander verbunden. Zur Verhinderung des Eindringens von Schmutz in das Rasierergehäuse, weist der Übergang 3 einen Faltenbalg 3a auf. Im Körper 1 des Rasierapparates befindet sich der insgesamt mit 4 bezeichnete Antrieb für den Scherkopf 2. Dieser Antrieb, der vorzugsweise mittels eines Elektromotors (nicht dargestellt) erfolgt, besitzt ein Kurbelelement 5, das auf der Welle 5a des Antriebsmotors gelagert ist. Dieses Kurbelelement 5 ist durch eine Kurbelstange 6 gelenkig mit einem weiteren am Scherkopf angeordneten Kurbelelement 7 verbunden. Dieses Kurbelelement 7 ist im Schnittpunkt der Vertikal- und Horizontalachse des Scherkopfes starr, beispielsweise durch eine Achse 7a am Scherkopf angeordnet. Diese Achse 7a befindet sich in einer Ebene zu der Welle 5a, durch die das Kurbelelement 5 mittels des Elektromotors angetrieben wird. Die Größe des Kurbelelementes 5 ist gegenüber der Größe des Kurbelelementes 7 derart gewählt, daß das Kurbelelement 7 in jedem Fall länger ist. Hierdurch wird erreicht, daß selbst bei einer vollen Umdrehung des Kurbelelementes 5 das Kurbelelement 7 eine entsprechend seiner Länge geringere Winkeldrehung durchführt. D. h. die Größe der Pendelbewegung des Scherkopfes ist unmittelbar abhängig von der Dimensionierung des Kurbelelementes 5 zu dem Kurbelelement 7.The shaver consists of the body 1 and the shaving head 2 . The body 1 and the shaving head 2 are connected to one another by an articulated transition 3 . To prevent the penetration of dirt into the razor housing, the transition 3 has a bellows 3 a. The body 1 of the shaving apparatus contains the drive for the shaving head 2 , which is designated overall by 4 . This drive, which is preferably carried out by means of an electric motor (not shown), has a crank element 5 which is mounted on the shaft 5 a of the drive motor. This crank element 5 is articulated by a crank rod 6 to a further crank element 7 arranged on the shaving head. This crank element 7 is rigid at the intersection of the vertical and horizontal axes of the shaving head, for example by an axis 7 a on the shaving head. This axis 7 a is located in a plane to the shaft 5 a through which the crank element 5 is driven by means of the electric motor. The size of the crank element 5 is chosen relative to the size of the crank element 7 such that the crank element 7 is longer in any case. It is hereby achieved that even with a full revolution of the crank element 5, the crank element 7 performs an angular rotation which is smaller in accordance with its length. That is, the size of the oscillating movement of the shaving head is directly dependent on the dimensioning of the crank element 5 to the crank element 7 .
