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-A 1 703 196 bekannt.The invention relates to a dry shaving apparatus with a sliding roller shutter, which is used for optionally covering or releasing a screen shaving foil of the dry shaving apparatus and from which, when the roller shutter is moved in the direction away from the screen 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-A 1 703 196.

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-A 2 750 795. 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 sieve shaving foil, the roller shutter can be pushed completely onto the base apparatus from the sieve shearing 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 widely known per se, see for example DE-A 2 750 795. 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 ready for shaving, a further position of the roller shutter is secured by a catch in which the screen shaving foil and the shaving head frame from Roller shutters are released, but the motor circuit is interrupted from the roller shutters. 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 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, 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 structural design is obtained, since only an additional catch 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 attached to the basic apparatus and secured by a latching device are visible for these layers. In this way, the user is signaled that the roller shutter is actually in the desired position.

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 catch for the roller shutter 3, the grip 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 which is closed off with a cover 16 and in which the ball 14 is inserted together with a spring 18, and 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 Rolladens 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 shown in FIG. 4, in the present exemplary embodiment, this further position of the roller shutter 3 is selected such that, viewed in the direction of displacement of the roller shutter away from the screen shaving foil 9, it 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 protruding 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 moved 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, which is secured by a latch, it can then be inoperable Dry shaving apparatus of the shaving head frame 2 can be removed unhindered from the roller shutter 3 from the basic apparatus 1, for example in order to carry out cleaning or to replace the screen shaving foil, whereby no damage to the roller shutter, the shaving head frame or the screening shear foil can take place since 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 further away from the screen shaving foil from this position secured by the balls 23 and 24, it then reaches the position secured by the balls 14 and 15, in which the motor circuit is closed from 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, but now in the direction of displacement of the roller shutter from the Seen from the screen shear 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 to couple 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 switch 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 was closed, as a result of which in this position of the roller shutter 3 the dry shaving apparatus, with the shutter 3 being released for shaving Siebscher Folie 9, is ready for use. 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 secured by the balls 14 and 15 described above, 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 completely pushed 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. During this further displacement of the roller shutter 3, the switching arm 25 is again taken along by the roller shutter 3, as a result of which the switching arm is brought from its switched-on position to its second switched-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 again 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 to 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 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 by the roller shutter 3, with the result that the switching arm 25, from the on the handle part 10 of the shutter 3 provided recess 27 disengages and thus the coupling of the switching arm 25 is released with the roller shutter 3, so that it can then be moved by itself until it finally completely covers the screen shear film 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, another 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. 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. 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.
