Description

Die Erfindung betrifft einen Trockenrasierapparat mit einem verschiebbaren Rolladen, der zum wahlweisen Abdecken oder Freigeben einer Siebscherfolie des Trockenrasier­apparates dient und von dem her, bei Verschiebung des Rolla­dens in Richtung von der Siebscherfolie weg und vom Rolladen zum Rasieren freigegebener Siebscherfolie, der Motorstrom­kreis für den Antrieb des Trockenrasierapparates geschlossen wird, wobei eine solche Lage des Rolladens durch eine Rast gesichert ist. Ein derartiger Trockenrasierapparat ist aus der DE-OS 17 03 196 bekannt.The invention relates to a dry shaving apparatus with a sliding roller shutter, which is used to selectively cover or release a sieve shaving foil of the dry shaving apparatus and from which, when the roller shutter is displaced in the direction away from the sieve shaving foil and from the roller shutter released for shaving, the motor circuit for driving the Dry shaver is closed, such a position of the roller shutter is secured by a catch. Such a dry shaver is known from DE-OS 17 03 196.

Die Erfindung hat sich zum Ziel gesetzt, einen Trockenra­sierapparat der eingangs angeführten Gattung besonders bedie­nungsfreundlich auszugestalten und Fehlbedienungen zu verhin­dern. Erfindungsgemäß ist hiezu vorgesehen, daß bei einem Trockenrasierapparat, der einen an einem Grundapparat lösbar gehaltenen, die Siebscherfolie tragenden Scherkopfrahmen auf­weist, der Rolladen von der Siebscherfolie her vollständig auf den Grundapparat schiebbar ist, wobei eine weitere Lage des Rolladens durch eine Rast gesichert ist, in welcher die Siebscherfolie und der Scherkopfrahmen vom Rolladen freige­geben sind und vom Rolladen her der Motorstromkreis unterbro­chen ist. Trockenrasierapparate, die einen an einem Grund­apparat lösbar gehaltenen, die Siebscherfolie tragenden Scherkopfrahmen aufweisen, geben einem Benützer eine einfache Möglichkeit, nach Abnahme des Scherkopfrahmens vom Grund­apparat, eine Reinigung vorzunehmen oder die Siebscherfolie auszutauschen. Solche Trockenrasierapparate sind an sich vielfach bekannt, siehe beispielsweise die DE-OS 27 50 795. Ein solcher Trockenrasierapparat wird nun mit einem Rolladen zum wahlweisen Abdecken oder Freigeben einer Siebscherfolie ausgerüstet, der von der Siebscherfolie her vollständig auf den Grundapparat schiebbar ist, wobei zusätzlich zu der durch eine Rast gesicherten Lage des Rolladens, in welcher die Siebscherfolie vom Rolladen zum Rasieren freigegeben, der Motorstromkreis geschlossen und der Trockenrasierapparat da­mit zum Rasieren betriebsbereit ist, eine weitere Lage des Rolladens durch eine Rast gesichert wird, in welcher die Siebscherfolie und der Scherkopfrahmen vom Rolladen freigege­ben sind, aber vom Rolladen her der Motorstromkreis unterbro­chen ist. In dieser weiteren durch eine Rast gesicherten Lage des Rolladens kann dann der Scherkopfrahmen, unbehindert vom Rolladen, vom Grundapparat abgenommen werden, um den Trocken­rasierapparat zu reinigen oder die Siebscherfolie auszutau­schen, ohne daß dabei eine Beschädigung des Rolladens, des Scherkopfrahmens oder der Siebscherfolie eintreten kann.The invention has set itself the goal of making a dry shaver of the type mentioned particularly user-friendly and to prevent incorrect operation. According to the invention, it is provided that in the case of a dry shaving apparatus which has a shaving head frame which is detachably held on a base apparatus and carries the screen shaving foil, the roller shutter can be pushed completely onto the base apparatus from the screen shear foil, a further position of the roller shutter being secured by a catch, in which the screen shaving foil and the shaving head frame are released from the roller shutter and the motor circuit is interrupted from the roller shutter. Dry shavers that have a shaving head frame that is detachably held on a base apparatus and that carries the sieve shaving foil give a user a simple possibility of cleaning or replacing the sieve shaving foil after the shaving head frame has been removed from the base apparatus. Such dry shavers are well known per se, see for example DE-OS 27 50 795. Such a dry shaver is now equipped with a roller shutter for optionally covering or releasing a screen shaving foil, which can be pushed completely onto the base apparatus from the screen shaving foil, in addition to the position of the roller shutter secured by a catch, in which the screen shaving foil is released from the roller shutter for shaving, the motor circuit is closed and the dry shaving apparatus is thus ready for shaving, another location of the Roller shutter is secured by a catch in which the screen shaving foil and the shaving head frame are released from the roller shutter, but the motor circuit is interrupted from the roller shutter. In this further position of the roller shutter secured by a catch, the shaving head frame can be removed from the basic apparatus, unhindered by the roller shutter, in order to clean the dry shaving apparatus or to replace the screen shaving foil without damage to the roller shutter, the shaving head frame or the screen shaving foil.

In der Richtung der Verschiebung des Rolladens von der Siebscherfolie weg gesehen, kann dabei eine solche weitere durch eine Rast gesicherte Lage des Rolladens, in welcher die Siebscherfolie und der Scherkopfrahmen vom Rolladen freigege­ben sind und vom Rolladen her der Motorstromkreis unterbro­chen ist, entweder vor oder nach der durch eine Rast gesi­cherten Lage des Rolladens liegen, in welcher die Siebscher­folie vom Rolladen zum Rasieren freigegeben und vom Rolladen her der Motorstromkreis geschlossen ist. Als vorteilhaft hat sich erwiesen, wenn in der Richtung der Verschiebung des Rolladens von der Siebscherfolie weg gesehen, die weitere durch eine Rast gesicherte Lage des Rolladens, in welcher die Siebscherfolie und der Scherkopfrahmen vom Rolladen freigege­ben sind und vom Rolladen her der Motorstromkreis unterbro­chen ist, vor der durch eine Rast gesicherten Lage des Rolla­dens liegt, in welcher die Siebscherfolie vom Rolladen zum Rasieren freigegeben und vom Rolladen her der Motorstromkreis geschlossen ist. Auf diese Weise wird ein besonders einfacher konstruktiver Aufbau erhalten, da nur eine zusätzliche Rast für den Rolladen vorzusehen ist, bevor vom Rolladen her der Motorstromkreis geschlossen wird, dabei aber die Siebscherfo­lie und der Scherkopfrahmen schon vom Rolladen freigegeben sind.Seen in the direction of the displacement of the roller shutter away from the screen shear foil, such a further position secured by a latching of the roller shutter, in which the screen shear foil and the shaving head frame are released from the roller shutter and the motor circuit is interrupted by the roller shutter, either before or after the position of the roller shutter secured by a catch, in which the screen shaving foil is released from the roller shutter for shaving and the motor circuit is closed from the roller shutter. It has proven to be advantageous if, in the direction of the movement of the roller shutter away from the screen shaving foil, the further position of the roller shutter secured by a catch, in which the screen shaving foil and the shaving head frame are released from the roller shutter and the motor circuit is interrupted by the roller shutter, lies in front of the position of the roller shutter secured by a catch, in which the screen shaving foil is released from the roller shutter for shaving and the motor circuit is closed from the roller shutter. In this way, a particularly simple construction is obtained, since only an additional rest for the roller shutter is to be provided before the motor circuit is closed from the roller shutter, but the screen shaving foil and the shaving head frame are already released from the roller shutter.

Weiters hat sich als vorteilhaft erwiesen, wenn der Rolla­den mit einem Sichtfenster versehen ist, durch welches in den beiden durch eine Rast gesicherten Lagen des Rolladens am Grundapparat angebrachte Kennzeichnungen für diese Lagen sichtbar sind. Auf diese Weise wird dem Benützer signali­siert, daß sich der Rolladen tatsächlich in der gewünschten Lage befindet.Furthermore, it has proven to be advantageous if the roller shutter is provided with a viewing window through which the markings for these layers, which are secured to the basic apparatus by a latch, are visible. In this way, the user is signaled that the roller shutter is actually in the desired position.

Die Figuren 1 und 2 zeigen einen Trockenrasierapparat, der einen Grundapparat 1 und einen auf diesen aufgesetzten Scher­kopfrahmen 2 aufweist. Der Scherkopfrahmen 2 ist dabei auf hier nicht näher dargestellte Art und Weise, beispielsweise mit mindestens einem federnden Rastriegel, lösbar am Grund­apparat 1 gehalten. Ein solcher Scherkopfrahmen dient zur Halterung einer gewölbt verlaufenden Siebscherfolie, die in den Figuren 1 und 2 vollständig durch einen Rolladen 3 abge­deckt ist, um die Siebscherfolie bei Nichtgebrauch des Trockenrasierapparates zu schützen. Ein solcher Rolladen 3 ist am Trockenrasierapparat verschiebbar angeordnet, wobei er in am Trockenrasierapparat vorgesehenen nutförmigen, in den Figuren 1 und 2 durch strichlierte Linien angedeuteten, Füh­rungen 4 und 5 beidseitig seitlich geführt ist. Wie ersicht­lich, ist der Rolladen 3 vom Grundapparat 1 her über den Scherkopfrahmen 2 und die Siebscherfolie schiebbar, wozu sich die Führungen 4 und 5 für den Rolladen 3 vom Grundapparat 1 her in den Seitenwänden 6 und 7 des Scherkopfrahmens 2 fort­setzen, wo sie dann, an die Wölbung der Siebscherfolie ange­paßt, gekrümmt verlaufen. Soll der Trockenrasierapparat zum Rasieren verwendet werden, so wird der Rolladen 3 aus seiner in den Figuren 1 und 2 gezeigten Lage auf den Grundapparat 1 zurückgeschoben, bis er die Siebscherfolie zum Rasieren frei­gibt, wie dies Fig.3 zeigt, wobei er im vorliegenden Fall vollständig auf den Grundapparat 1 geschoben ist, so daß auch der Scherkopfrahmen 2 freigegeben ist, an dessen Längsstegen 8 die Siebscherfolie 9 gehalten ist. In dieser durch eine Rast gesicherten Lage des Rolladens, ist vom Rolladen her der Motorstromkreis für den Antrieb des Trockenrasierapparates geschlossen, so daß dieser zum Rasieren betriebsbereit ist.FIGS. 1 and 2 show a dry shaving apparatus which has a basic apparatus 1 and a shaving head frame 2 placed thereon. The shaving head frame 2 is detachably held on the base apparatus 1 in a manner not shown here, for example with at least one resilient latching bolt. Such a shaving head frame is used to hold a curved screen shaving foil which is completely covered by a roller shutter 3 in FIGS. 1 and 2 in order to protect the screen shaving foil when the dry shaving apparatus is not in use. Such a roller shutter 3 is slidably arranged on the dry shaving apparatus, wherein it is guided on both sides in the groove-shaped guides 4 and 5 provided on the dry shaving apparatus and indicated by dashed lines in FIGS. 1 and 2. As can be seen, the roller shutter 3 can be pushed from the basic apparatus 1 over the shaving head frame 2 and the screen shaving foil, for which purpose the guides 4 and 5 for the roller shutter 3 from the basic apparatus 1 continue in the side walls 6 and 7 of the shaving head frame 2, where they then, adapted to the curvature of the screen shear film, run curved. If the dry shaving apparatus is to be used for shaving, the roller shutter 3 is pushed back from its position shown in FIGS. 1 and 2 onto the basic apparatus 1 until it releases the screen shaving foil for shaving, as shown in FIG. 3, whereby in the present case it is complete is pushed onto the base apparatus 1, so that the shaving head frame 2 is also released, on the longitudinal webs 8 of which the screen shear film 9 is held. In this position of the roller shutter secured by a catch, the motor circuit for driving the dry shaving apparatus is closed from the roller shutter, so that it is ready for shaving.

Beim vorliegenden Ausführungsbeispiel weist der Rolladen 3 an seinem von der Siebscherfolie 9 abgewandten Ende eine Griffleiste 10 auf, so daß er einfach von Hand aus zu ver­schieben ist. Diese Griffleiste 10 des Rolladens 3 wird so­wohl zur Bildung einer Rast für den Rolladen als auch zum Schließen des Motorstromkreises herangezogen. Zur Bildung der Rast für den Rolladen 3 weist der Griffteil 10 an seiner dem Apparategehäuse 11 zugewandten Seite zwei mit Abstand neben­einander liegende, kalottenförmige Vertiefungen 12 und 13 auf, die zum Zusammenwirken mit aus dem Apparategehäuse 11 herausragenden Kugeln 14 und 15 vorgesehen sind. Sobald der Rolladen 3 in die in Fig.3 gezeigte Lage verschoben ist, rasten die Kugeln 14 und 15 in die Vertiefungen 12 und 13 ein und sichern so die Lage des Rolladens. Die Anordnung einer dieser Kugeln, beispielsweise der Kugel 14, am Apparategehäu­se 11, zeigt Fig.5. Am Apparategehäuse 11 ist hiezu ein Ku­gelkäfig vorgesehen, der durch einen mit einem Deckel 16 ab­geschlossenen hohlzylindrischen Ansatz 17 gebildet ist, in welchen die Kugel 14 zusammen mit einer Feder 18 eingesetzt ist, wobei sie dann durch eine im Apparategehäuse 11 vorge­sehene Öffnung 19 kalottenförmig herausragend bis in die Bahn des Griffteils 10 des Rolladens 3 reicht. Anstelle solcher Kugelrasten könnten natürlich auch im Rahmen des hierfür be­kannten Standes der Technik andere Rasten vorgesehen sein, wie beispielsweise hakenförmig oder gabelförmig ausgebildete Rasten. Auf dem Niveau dieser durch die Kugeln 14 und 15 ge­bildeten Rast ist im Apparategehäuse 11, wie dies Fig.6 zeigt, ein Tastschalter 20 angeordnet, der mit seinem Schalt­arm 21 durch eine im Apparategehäuse 11 vorgesehene Öffnung 22 hindurchragt, und zwar so weit, daß er bis in die Bahn des Griffteils 10 des Rolladens 3 reicht, so daß er durch den Griffteil 10 niederdrückbar ist, sobald der Griffteil 10, bei Verschiebung des Rolladens in Richtung von der Siebscherfolie weg, auf ihn aufläuft, wodurch der Tastschalter 20 geschlos­sen wird. Dieser Tastschalter 20 liegt im Motorstromkreis des Trockenrasierapparates , womit vom Rolladen 3 her der Motor­stromkreis geschlossen wird, sobald der Rolladen die in Figur 3 gezeigte lage einnimmt. In dieser Lage des Rolladens ist der Trockenrasierapparat dann zum Rasieren betriebsbereit.In the present exemplary embodiment, the roller shutter 3 has a grip strip 10 at its end facing away from the screen shear foil 9, so that it can be moved easily by hand. This grip strip 10 of the roller shutter 3 is used both to form a latch for the roller shutter and to close the motor circuit. To form the Rest for the roller shutter 3, the handle part 10 has on its side facing the apparatus housing 11 two spaced-apart, dome-shaped depressions 12 and 13, which are intended to interact with balls 14 and 15 projecting from the apparatus housing 11. As soon as the roller shutter 3 is moved into the position shown in FIG. 3, the balls 14 and 15 snap into the recesses 12 and 13 and thus secure the position of the roller shutter. The arrangement of one of these balls, for example the ball 14, on the apparatus housing 11 is shown in FIG. 5. For this purpose, a ball cage is provided on the apparatus housing 11, which is formed by a hollow cylindrical projection 17 closed off with a cover 16, in which the ball 14 is inserted together with a spring 18, which then protrudes in a dome shape through an opening 19 provided in the apparatus housing 11 extends into the path of the handle part 10 of the roller shutter 3. Instead of such ball catches, other catches could of course also be provided within the framework of the prior art known for this purpose, such as hook-shaped or fork-shaped catches. At the level of this detent formed by the balls 14 and 15, a pushbutton switch 20 is arranged in the apparatus housing 11, as shown in FIG. 6, with its switching arm 21 projecting through an opening 22 provided in the apparatus housing 11, to the extent that it extends into the path of the handle part 10 of the roller shutter 3, so that it can be pressed down by the handle part 10 as soon as the handle part 10, upon displacement of the roller shutter in the direction away from the screen shear film, runs onto it, whereby the key switch 20 is closed. This pushbutton switch 20 is located in the motor circuit of the dry shaving apparatus, so that the motor circuit is closed from the roller shutter 3 as soon as the roller shutter assumes the position shown in FIG. In this position of the roller shutter, the dry shaver is then ready for shaving.

An einem solchen Trockenrasierapparat ist nun eine weitere Rast für den Rolladen 3 vorgesehen, die eine Lage des Rolla­dens festlegt, in der dieser die Siebscherfolie und den Scherkopfrahmen freigibt, wobei aber vom Rolladen her der Mo­torstromkreis unterbrochen ist. Wie Fig.4 zeigt, ist beim vorliegenden Ausführungsbeispiel diese weitere Lage des Roll­ dens 3 so gewählt, daß sie, in der Richtung der Verschiebung des Rolladens von der Siebscherfolie 9 weg gesehen, vor der durch die Kugeln 14 und 15 gesicherten Lage des Rolladens liegt, in welcher vom Rolladen her der Motorstromkreis ge­schlossen ist. Hiezu sind zwei weitere, aus dem Apparatege­häuse 11 herausragende Kugeln 23 und 24 vorgesehen, welche ebenfalls in die Bahn des Griffteiles 10 des Rolladens 3 ra­gen und die, bei der Verschiebung des Rolladens von der Sieb­scherfolie weg, in die am Griffteil 10 vorgesehenen Vertie­fungen 12 und 13 einrasten. Wie ersichtlich, ist in einer solchen weiteren Lage des Rolladens, in welcher der Rolladen die Siebscherfolie und den Scherkopfrahmen freigibt, der im Motorstromkreis liegende Tastschalter 20 vom Rolladen 3 her nicht betätigt, da der Griffteil 10 des Rolladens den Schalt­arm 21 noch nicht erreicht hat, so daß der Motorstromkreis unterbrochen ist. Dies wird auf besonders einfache Weise nur durch das Vorsehen der beiden weiteren Kugeln 23 und 24 er­reicht. In dieser weiteren durch eine Rast gesicherten Lage des Rolladens kann dann bei nicht betriebsbereitem Trocken­rasierapparat der Scherkopfrahmen 2 unbehindert vom Rolladen 3 vom Grundapparat 1 abgenommen werden, um beispielsweise eine Reinigung vorzunehmen oder die Siebscherfolie auszutau­schen, wobei keine Beschädigung des Rolladens, des Scherkopf­rahmens oder der Siebscherfolie erfolgen kann, da sich der Rolladen 3 vollständig am Grundapparat 1 befindet.On such a dry shaving apparatus, a further catch for the roller shutter 3 is now provided, which defines a position of the roller shutter in which it releases the screen shaving foil and the shaving head frame, but the motor circuit is interrupted by the roller shutter. As FIG. 4 shows, this further position of the roll is in the present exemplary embodiment dens 3 chosen so that, seen in the direction of the displacement of the roller shutter away from the screen shaving foil 9, lies in front of the position of the roller shutter secured by the balls 14 and 15, in which the motor circuit is closed from the roller shutter. For this purpose, two further balls 23 and 24 projecting from the apparatus housing 11 are provided, which likewise protrude into the path of the handle part 10 of the roller shutter 3 and which, when the roller shutter is displaced away from the screen shear film, into the recesses 12 and 12 provided on the handle part 10 13 click into place. As can be seen, in such a further position of the roller shutter, in which the roller shutter releases the screen shaving foil and the shaving head frame, the pushbutton switch 20 in the motor circuit is not actuated from the roller shutter 3, since the handle part 10 of the roller shutter has not yet reached the switching arm 21, so that the motor circuit is interrupted. This is achieved in a particularly simple manner only by the provision of the two further balls 23 and 24. In this further position of the roller shutter secured by a catch, the shaving head frame 2 can then be removed unhindered from the roller shutter 3 by the basic apparatus 1 when the dry shaving apparatus is not ready for operation, for example to carry out cleaning or to replace the screen shaving foil, with no damage to the roller shutter, the shaving head frame or the screen shaving foil can take place because the roller shutter 3 is completely on the basic apparatus 1.

Wird der Rolladen aus dieser durch die Kugeln 23 und 24 gesicherten Lage heraus weiter von der Siebscherfolie weg verschoben, so erreicht er dann die durch die Kugeln 14 und 15 gesicherte Lage, in der dann vom Rolladen 3 her der Motor­stromkreis geschlossen und der Trockenrasierapparat zum Ra­sieren betriebsbereit ist, wie dies anhand von Fig.3 erläu­tert wurde. Wie ersichtlich, sind beim vorliegenden Ausfüh­rungsbeispiel in beiden durch eine Rast gesicherten Lagen des Rolladens die Siebscherfolie und der Scherkopfrahmen vom Rolladen freigegeben.If the roller shutter is moved out of this position secured by the balls 23 and 24 further away from the screen shaving foil, it then reaches the position secured by the balls 14 and 15, in which the motor circuit is closed by the roller shutter 3 and the dry shaving apparatus for shaving is ready for operation, as was explained with reference to FIG. 3. As can be seen, in the present exemplary embodiment, the screen shaving foil and the shaving head frame are released from the roller shutter in both positions of the roller shutter secured by a catch.

Beim Ausführungsbeispiel nach den Figuren 7, 8 und 9 sind zur Sicherung der beiden Lagen des Rolladens 3 wieder Kugel­rasten vorgesehen, die mit kalottenförmigen Vertiefungen 12 und 13 am Griffteil 10 des Rolladens 3 zusammenwirken, wobei aber nunmehr in der Richtung der Verschiebung des Rolladens von der Siebscherfolie weg gesehen, die Lage des Rolladens, in welcher vom Rolladen her der Motorstromkreis geschlossen ist, vor der weiteren Lage des Rolladens liegt, in welcher vom Rolladen her der Motorstromkreis unterbrochen ist. Demge­mäß liegen, in der Richtung der Verschiebung des Rolladens von der Siebscherfolie weg gesehen, die mit 14 und 15 be­zeichneten Kugeln vor den mit 23 und 24 bezeichneten Kugeln, um die gleiche Bezeichnungsweise wie beim vorhergehend be­schriebenen Ausführungsbeispiel zu wählen. Zum Unterbrechen und Schließen des Motorstromkreises wird hier ein Schiebe­schalter verwendet, der in der Verschiebungsrichtung gesehen, drei Stellungen aufweist, und zwar nacheinander eine erste Ausschaltstellung, eine Einschaltstellung und eine zweite Ausschaltstellung. Der Schaltarm 25 eines solchen, hier nicht näher dargestellten Schiebeschalters ragt dabei aus einem im Apparategehäuse 11 vorgesehenen Schlitz 26 heraus, und zwar wieder bis in die Bahn des Griffteiles 10 des Rollladens 3. Korrespondierend zu diesem Schaltarm 25 ist an der dem Appa­rategehäuse 11 zugewandten Seite des Griffteiles 10 des Roll­ladens 3 eine weitere Vertiefung 27 vorgesehen, die zur Kupp­lung des Griffteiles 10 und damit des Rolladens 3 mit dem Schaltarm 25 dient.In the exemplary embodiment according to FIGS. 7, 8 and 9, ball catches are again provided to secure the two layers of the roller shutter 3, which cooperate with spherical depressions 12 and 13 on the handle part 10 of the roller shutter 3, wherein but now seen in the direction of the displacement of the roller shutter away from the Siebscher film, the position of the roller shutter, in which the motor circuit is closed from the roller shutter, lies before the further position of the roller shutter, in which the motor circuit is interrupted by the roller shutter. Accordingly, viewed in the direction of displacement of the roller shutter away from the screen shaving foil, the balls labeled 14 and 15 lie in front of the balls labeled 23 and 24 in order to choose the same designation as in the previously described embodiment. To interrupt and close the motor circuit, a slide switch is used here, which, viewed in the direction of displacement, has three positions, namely a first switch-off position, a switch-on position and a second switch-off position. The switching arm 25 of such a slide switch, not shown here, protrudes from a slot 26 provided in the device housing 11, again into the path of the handle part 10 of the roller shutter 3. Corresponding to this switching arm 25 is on the side facing the device housing 11 of the handle part 10 of the roller shutter 3, a further recess 27 is provided, which serves for coupling the handle part 10 and thus the roller shutter 3 with the switching arm 25.

Wird der Rolladen aus der in Fig.7 gezeigten Lage von der Siebscherfolie weg verschoben, so kommt es, sobald der Griff­teil 10 den Schaltarm 25 erreicht, zu einem Einrasten des Schaltarmes 25 in die Vertiefung 27 am Griffteil 10 und damit zu einer Kupplung des Rolladens 3 mit dem Schaltarm 25. Bei einer weiteren Verschiebung des Rolladens 3 von der Sieb­scherfolie weg wird dann der Schaltarm 25 vom Rolladen 3 mit­genommen, bis die Kugeln 14 und 15 in die Ausnehmungen 12 und 13 am Griffteil 10 des Rolladens 3 einrasten und eine Lage­sicherung für den Rolladen 3 bewirken. In dieser Lage des Rolladens 3 ist die Siebscherfolie 9 bereits vom Rolladen 3 zum Rasieren freigegeben, nicht jedoch der Scherkopfrahmen 2, wie dies Fig.8 zeigt. Durch die erfolgte Mitnahme des Schalt­armes 25 durch den Rolladen 3 wurde der Schiebeschalter von seiner ersten Ausschaltstellung in seine Einschaltstellung gebracht und damit der Motorstromkreis für den Antrieb des Trockenrasierapparates geschlossen, wodurch in dieser Lage des Rolladens 3 der Trockenrasierapparat, bei vom Rolladen 3 zum Rasieren freigegebener Siebscherfolie 9, betriebsbereit ist. Falls erwünscht, könnte aber auch hier die durch die Ku­geln 14 und 15 gesicherte Lage des Rolladens 3, bei einem entsprechend langen Verschiebeweg für den Rolladen 3, so ge­wählt werden, daß der Rolladen 3 vollständig auf den Grund­apparat 1 geschoben ist und damit die Siebscherfolie 9 und der Scherkopfrahmen 2 vom Rolladen 3 freigegeben sind, wie dies beim Ausführungsbeispiel nach den Figuren 1 bis 4 der Fall war.If the roller shutter is moved away from the screen shear film from the position shown in FIG. 7, as soon as the handle part 10 reaches the switching arm 25, the switching arm 25 snaps into the recess 27 on the handle part 10 and thus the roller shutter is coupled 3 with the switching arm 25. When the roller shutter 3 is moved further away from the screen shaving foil, the switching arm 25 is then carried along by the roller shutter 3 until the balls 14 and 15 engage in the recesses 12 and 13 on the handle part 10 of the roller shutter 3 and secure the position cause the roller shutter 3. In this position of the roller shutter 3, the screen shaving foil 9 has already been released by the roller shutter 3 for shaving, but not the shaving head frame 2, as shown in FIG. 8. Due to the fact that the switching arm 25 was taken along by the roller shutter 3, the slide switch was brought from its first switch-off position to its switch-on position and thus the motor circuit for driving the Dry shaving apparatus closed, whereby in this position of the roller shutter 3 the dry shaving apparatus is ready for operation when the screen shaving foil 9 is released from the roller shutter 3 for shaving. If desired, the position of the roller shutter 3 secured by the balls 14 and 15, with a correspondingly long displacement path for the roller shutter 3, could also be selected here such that the roller shutter 3 is pushed completely onto the basic apparatus 1 and thus the screen shear foil 9 and the shaving head frame 2 are released from the roller shutter 3, as was the case in the exemplary embodiment according to FIGS. 1 to 4.

Aus der vorstehend beschriebenen, durch die Kugeln 14 und 15 gesicherten Lage des Rolladens 3 ist dieser nunmehr noch weiter in Richtung von der Siebscherfolie weg verschiebbar, bis die Kugeln 23 und 24 in die Ausnehmungen 12 und 13 am Griffteil 10 des Rolladens 3 einrasten, und damit eine weite­re Lage des Rolladens sichern. In dieser weiteren Lage des Rolladens 3 ist dieser jetzt vollständig auf den Grundapparat 1 geschoben, wodurch er sowohl die Siebscherfolie 9 als auch den Scherkopfrahmen 2 freigibt, wie dies Fig.9 zeigt. Bei dieser weiteren Verschiebung des Rolladens 3 wird wieder der Schaltarm 25 vom Rolladen 3 her mitgenommen, wodurch dieser den Schiebeschalter von seiner Einschaltstellung in seine zweite Ausschaltstellung bringt, wodurch der Motorstromkreis unterbrochen ist. In dieser durch die Kugeln 23 und 24 gesi­cherten weiteren Lage des Rolladens 3, in welcher der Trockenrasierapparat nicht betriebsbereit ist, kann dann der Scherkopfrahmen 2 vom Rolladen 3 unbehindert vom Grundapparat 1 abgenommen werden, um beispielsweise eine Reinigung vorzu­nehmen oder die Siebscherfolie auszutauschen.From the position of the roller shutter 3 described above, which is secured by the balls 14 and 15, the latter can now be moved even further in the direction away from the screen shear foil until the balls 23 and 24 snap into the recesses 12 and 13 on the handle part 10 of the roller shutter 3, and secure another position of the roller shutter. In this further position of the roller shutter 3, it is now pushed completely onto the basic apparatus 1, whereby it releases both the screen shaving foil 9 and the shaving head frame 2, as shown in FIG. 9. With this further displacement of the roller shutter 3, the switching arm 25 is again carried along by the roller shutter 3, as a result of which the switching arm is brought from its switch-on position to its second switch-off position, as a result of which the motor circuit is interrupted. In this further position of the roller shutter 3, which is secured by the balls 23 and 24 and in which the dry shaving apparatus is not ready for operation, the shaving head frame 2 can then be removed from the roller shutter 3 unhindered by the base apparatus 1, for example in order to carry out cleaning or to replace the screen shaving foil.

Wird der Rolladen 3 aus dieser weiteren durch die Kugeln 23 und 24 gesicherten Lage in entgegengesetzter Richtung zur Siebscherfolie 9 hin verschoben, so gelangt der Rolladen 3 wieder in die durch die Kugeln 14 und 15 gesicherte Lage, wo­bei wieder der Schaltarm 25 mitgenommen und der Schiebeschal­ter aus seiner zweiten Ausschaltstellung in seine Einschalt­stellung gebracht wird und damit der Trockenrasierapparat wieder betriebsbereit ist. Bei weiterer Verschiebung des Rolladens 3 zur Siebscherfolie 9 hin verläßt der Rolladen 3 die durch die Kugeln 14 und 15 gesicherte Lage, wobei er wie­der den Schaltarm 25 mitnimmt und dieser den Schiebeschalter in seine erste Ausschaltstellung bringt, wodurch der Motor­stromkreis wieder unterbrochen wird. Bei noch weiterer Ver­schiebung des Rolladens 3 zur Siebscherfolie 9 hin erreicht der Schaltarm 25 seine durch den im Apparategehäuse 11 vorge­sehenen Schlitz 26 begrenzte Endlage, über die hinaus er nicht mehr vom Rolladen 3 mitgenommen werden kann, was zur Folge hat, daß der Schaltarm 25, aus der am Griffteil 10 des Rolladens 3 vorgesehenen Vertiefung 27 ausrastet und damit die Kupplung des Schaltarmes 25 mit dem Rolladen 3 gelöst wird, so daß dieser dann für sich alleine weiter verschoben werden kann, bis er schließlich die Siebscherfolie 9 voll­ständig abdeckt.If the roller shutter 3 is moved from this further position secured by the balls 23 and 24 in the opposite direction to the screen shear foil 9, the roller shutter 3 returns to the position secured by the balls 14 and 15, the switching arm 25 being carried along and the slide switch is brought from its second switch-off position to its switch-on position and the dry shaver is thus ready for operation again. When the roller shutter 3 is moved further toward the screen shear foil 9, the roller shutter 3 leaves the position secured by the balls 14 and 15, again taking the switching arm 25 with it and this bringing the slide switch into its first switch-off position, as a result of which the motor circuit is interrupted again. If the roller shutter 3 is moved even further towards the screen shear foil 9, the switching arm 25 reaches its end position limited by the slot 26 provided in the apparatus housing 11, beyond which it can no longer be carried along by the roller shutter 3, with the result that the switching arm 25, disengages from the recess 27 provided on the handle part 10 of the roller shutter 3 and thus the coupling of the switching arm 25 with the roller shutter 3 is released, so that the latter can then be moved on its own until it finally completely covers the screen shear foil 9.

Im Hinblick auf eine für einen Benützer des Trockenrasier­apparates deutliche Kennzeichnung der beiden durch eine Rast gesicherten Lagen des Rolladens 3 hat sich als vorteilhaflt erwiesen, wenn der Rolladen mit einem Sichtfenster versehen wird, durch welches in diesen beiden Lagen des Rolladens am Grundapparat 1 angebrachte Kennzeichnungen für diese Lagen sichtbar sind. Wie aus den Figuren 10 und 11 ersichtlich ist, ist ein solches Sichtfenster 28 beispielsweise im Griffteil 10 des Rolladens 13 vorgesehen. In der durch die Kugeln 14 und 15 gesicherten Lage des Rolladens 3, in welcher die Sieb­scherfolie 9 vom Rolladen 3 zum Rasieren freigegeben und vom Rolladen 3 her der Motorstromkreis geschlossen ist, ist dann beispielsweise, wie Fig.10 zeigt, durch das Sichtfenster 28 der Schriftzug "EIN" zu sehen, was die Betriebsbereitschaft des Trockenrasierapparates zum Rasieren kennzeichnet. In der durch die Kugeln 23 und 24 gesicherten Lage des Rolladens 3, in welcher die Siebscherfolie 9 und der Scherkopfrahmen 2 vom Rolladen 3 freigegeben sind und vom Rolladen 3 her der Motor­stromkreis unterbrochen ist, ist dann beispielsweise, wie Fig. 11 zeigt, das Symbol einer Bürste zu sehen, was angibt, daß der Scherkopfrahmen 2 vom Rolladen 3 unbehindert vom Grundapparat 1 abgenommen werden kann, um beispielsweise eine Reinigung vorzunehmen. Beispielsweise könnte am Grundapparat 1 auch noch ein weiteres symbol vorgesehen sein, das in der Lage des Rolladens 3 durch das Sichtfenster 28 zu sehen ist, in welcher der Rolladen 3 die Siebscherfolie 9 vollständig abdeckt und schützt.With regard to a clear identification of the two positions of the roller shutter 3 secured by a catch for a user of the dry shaving apparatus, it has proven to be advantageous if the roller shutter is provided with a viewing window through which the markings for the roller shutter in these two layers are attached these layers are visible. As can be seen from FIGS. 10 and 11, such a viewing window 28 is provided, for example, in the handle part 10 of the roller shutter 13. In the position of the roller shutter 3 secured by the balls 14 and 15, in which the screen shaving foil 9 is released from the roller shutter 3 for shaving and the motor circuit is closed from the roller shutter 3, for example, as shown in FIG Lettering "ON" to see what indicates the operational readiness of the dry shaver for shaving. In the position of the roller shutter 3 secured by the balls 23 and 24, in which the screen shaving foil 9 and the shaving head frame 2 are released from the roller shutter 3 and the motor circuit is interrupted from the roller shutter 3, the symbol is then, for example, as shown in FIG. 11 a brush to see, which indicates that the shaving head frame 2 can be removed from the roller shutter 3 unhindered from the basic apparatus 1, for example to carry out cleaning. For example, a further symbol could also be provided on the basic apparatus 1, which can be seen in the position of the roller shutter 3 through the viewing window 28, in which the roller shutter 3 completely covers and protects the screen shear foil 9.

Selbstverständlich bestehen noch eine Reihe von Abwand­lungsmöglichkeiten der im vorstehend beschriebenen Ausfüh­rungsbeispiele, ohne daß dabei der Rahmen der Erfindung ver­lassen wird. Dies gilt insbesondere im Hinblick auf die Aus­bildung der die beiden Lagen des Rolladens sichernden Rasten sowie die Art und Weise des Ein- und Ausschaltens des Motor­stromkreises des Trockenrasierapparates.Of course, there are still a number of possible modifications to the exemplary embodiments described above, without thereby leaving the scope of the invention. This applies in particular with regard to the design of the catches securing the two layers of the roller shutter and the manner in which the motor circuit of the dry shaving apparatus is switched on and off.
