In a dry-shaver having a shaving-head frame (2) which can be mounted on a housing (1), the said shaving-head frame is firmly held by a bar (7) projecting from a side wall (5) of the housing and movable counter to the action of a spring (6), which bar can be moved by an operating member (9) arranged on the shaving-head frame to release the shaving-head frame from the housing, the operating member carrying a projection (11) which cooperates with a sloping surface (12) arranged at the free end of the bar and forming a run-down ramp for the shaving-head frame, as a result of which a force component is produced which tends to release the shaving-head frame from the housing. <IMAGE>

Description

Die Erfindung betrifft einen Trockenrasierapparat mit einem Gehäuse und einem auf dasselbe aufsetzbaren, ein Obermesser tragenden Scherkopfrahmen, der mit mindestens einem aus einer Seitenwand des Gehäuses herausragenden, quer zu derselben entgegen der Wirkung einer Feder verstellbaren, an seinem freien Ende eine der Aufsetzrichtung des Scherkopfrahmens auf das Gehäuse zugewandte mit der sich in dieser Aufsetzrichtung vom Riegel weg erstreckenden betreffenden Seitenwand des Gehäuses einen spitzen Winkel bildende, im wesentlichen schräg verlaufende Fläche aufweisenden Riegel am Gehäuse festgehalten ist, wobei der Riegel mit einem seiner schräg verlaufenden Fläche gegenüberliegenden Abschnitt seines freien Endes eine am Scherkopfrahmen vorgesehene Rast hintergreift, und der zum Lösen des Riegels von der Rast ein dem Riegen gegenüberliegendes, von Hand aus in Richtung zum Riegel hin verstellbares Bedienungsorgan aufweist, das mit einem zum Riegel hin vorspringenden Ansatz versehen ist, dessen freies Ende beim Betätigen des Bedienungsorganes mit dem freien Ende des Riegels zusammenwirkt, wobei der Riegel entgegen der Wirkung der Feder verstellt wird und der Scherkopfrahmen nach Freistellung des Riegels von der Rast am Scherkopfrahmen aus seiner am Gehäuse festgehaltenen Lage lösbar ist.The invention relates to a dry shaving apparatus with a housing and a shaving head frame which can be placed on the same and carries an upper knife, which has at least one of the mounting direction of the shaving head frame on its free end with at least one protruding from a side wall of the housing and adjustable transversely to the action of a spring the housing facing with the side wall of the housing extending in this mounting direction away from the bolt and forming an acute angle, having an essentially obliquely extending surface, the bolt is held on the housing, the bolt having a portion of its free end opposite its inclined surface Shaving head frame provided catch engages, and which for releasing the latch from the latch opposite the latch, adjustable by hand in the direction of the latch towards the operating member, which verses with a projecting towards the latch marriages, the free end of which cooperates with the free end of the bolt when the operating element is actuated, the bolt being adjusted against the action of the spring and the shaving head frame being releasable from its position on the housing after the bolt has been released from the catch on the shaving head frame.

Ein derartiger Trockenrasierapparat ist aus der DE-A 25 19 881 bekannt. Bei diesem bekannten Trockenrasierapparat ist das einem Riegel am Gehäuse zugeordnete Bedienungsorgan am Scherkopfrahmen in Richtung zum Riegel hin verschiebbar angeordnet, wobei das senkrecht zur Verschiebungsrichtung ebenflächig ausgebildete freie Ende des am Bedienungsorgan vorgesehenen Ansatzes mit der Spitze des kegelig ausgebildeten freien Endes des Riegels zusammenwirkt. Zum Lösen des Scherkopfrahmens aus seiner am Gehäuse festgehaltenen Lage ist es notwendig, auf das Bedienungsorgan einen Druck auszuüben, bis der Riegel von der Rast am Scherkopfrahmen freigestellt ist und dabei in zur Druckrichtung senkrechter Richtung eine vom Gehäuse weg gerichtete Zugkraft auszuüben.Such a dry shaver is known from DE-A 25 19 881. In this known dry shaving apparatus, the operating element assigned to a bolt on the housing is arranged on the shaving head frame so as to be displaceable in the direction of the bolt, with the free end of the extension provided on the operating element, which is flat and perpendicular to the direction of displacement, cooperating with the tip of the conically shaped free end of the bolt. To release the shaving head frame from its position held on the housing, it is necessary to exert pressure on the operating element until the latch is released from the catch on the shaving head frame and to exert a tensile force away from the housing in the direction perpendicular to the pressure direction.

Um das Lösen des Scherkopfrahmens aus seiner am Gehäuse festgehaltenen Lage zu erleichtern, ist bei einem anderen, aus der DE-A 34 15 121 bekannten Trockenrasierapparat am Bedienungsorgan eine zum Zusammenwirken mit dem freien Ende des Riegels dienende Fläche vorgesehen, die im Zusammenwirken mit dem freien Ende des Riegels beim Betätigen des Bedienungsorganes durch ihre Neigung eine Ablauframpe bildet, wodurch bewirkt wird, daß eine auf den Scherkopfrahmen einwirkende Kraftkomponente entsteht, die vom Gehäuse weg gerichtet ist und daher das Lösen des Scherkopfrahmens vom Gehäuse begünstigt. Dadurch, daß die mit dem freien Ende des Riegels zusammenwirkende Ablauframpe am Bedienungsorgan vorgesehen ist, unterliegt jedoch ihre Dimensionierung hinsichtlich ihrer Neigung aus Platzgründen wesentlichen Beschränkungen, so daß die durch sie entstehende, auf den Scherkopfrahmen einwirkende kraftkomponente keinen entscheidenden Beitrag zum Lösen des Scherkopfrahmens vom Gehäuse leistet. Dies ist darauf zurückzuführen, daß zwischen der den Riegel aufweisenden Gehäusewand des Trockenrasierapparates und dem Scherkopfrahmen nur wenig Platz zur Verfügung steht, nämlich nur so viel, als für die Verriegelung des Scherkopfrahmens am Gehäuse durch das freie Ende des Riegels erforderlich ist, so daß die Niegung der Ablauframpe bei ihrem Zusammenwirken mit dem freien Ende des Riegels disem gegenüber nur wenig unterschiedlich gegenüber 90 gewählt werden kann, wodurch die vom Gehäuse weg gerichtete, auf den Scherkopfrahmen einwirkende Kraftkomponente dementsprechend klein ist.In order to facilitate the detachment of the shaving head frame from its position held on the housing, in another dry shaver known from DE-A 34 15 121 on the operating member a surface is provided for interacting with the free end of the bolt, which cooperates with the free surface End of the bolt forms a drain ramp when actuating the operating element by its inclination, which causes a force component acting on the shaving head frame to arise which is directed away from the housing and therefore favors the release of the shaving head frame from the housing. Due to the fact that the discharge ramp cooperating with the free end of the bolt is provided on the operating member, its dimensioning is subject to significant restrictions with regard to its inclination for reasons of space, so that the force component which it produces and acts on the shaving head frame makes no decisive contribution to detaching the shaving head frame from the housing accomplishes. This is due to the fact that only little space is available between the housing wall of the dry shaving apparatus which has the bolt and the shaving head frame, namely only as much as is necessary for the locking of the shaving head frame on the housing by the free end of the bolt, so that the bend the discharge ramp, when interacting with the free end of the latch, can be chosen only slightly different from that relative to 90, as a result of which the force component directed away from the housing and acting on the shaving head frame is correspondingly small.

Die Erfindung hat sich zum Ziel gesetzt, bei einem Trockenrasierapparat der eingangs angeführten Gattung Maßnahmen zu treffen, durch die das Lösen des Scherkopfrahmens aus seiner am Gehäuse festgehaltenen Lage besonders leicht dadurch möglich ist, daß es von einer dabei entstehenden besonders wirkungsvollen Kraftkomponente unterstützt wird. Die Erfindung weist hiezu das Kennzeichen auf, daß das freie Ende des am Bedienungsorgan vorgesehenen Ansatzes der schräg verlaufenden Fläche am freien Ende des Riegels gegenüberliegt und bei Betätigung des Bedienungsorgans mit dieser schräg verlaufenden, eine Ablauframe bildenden Fläche zusammenwirkt.Auf diese Weise ist erreicht, daß die von sich aus bereits schräg verlaufende Fläche am freien Ende des Riegels eine Ablauframpe bildet, mit der das freie Ende des vom Bedienungsorgan vorspringenden Ansatzes zusammenwirkt, wobei sich durch den ausgeprägten schrägen Verlauf dieser Fläche eine wirkungsvolle, vom Gehäuse weg gerichtete Kraftkomponente ergibt, die das Lösen des Scherkopfrahmens aus seiner am Gehäuse festgehaltenen Lage deutlich merkbar unterstützt, wodurch sich für den Benützer, der das Bedienungsorgan betätigt, das Gefühl ergibt, daß ihm der Scherkopfrahmen, nachdem der Riegel von der Rast am Scherkopfrahmen freigestellt ist, sozusagen entgegenkommt. Dies ergibt einen besonderen Bedienungskomfort, da die Bedienungsperson beim Betätigen des Bedienungsorgans nicht gleichzeitig dieses Niederdrücken und außerdem noch am Scherkopfrahmen relativ stark anziehen muß.The invention has set itself the goal of taking measures in a dry shaver of the type mentioned at the outset, by means of which it is particularly easy to release the shaving head frame from its position held on the housing in that it is supported by a particularly effective force component which arises in the process. To this end, the invention is characterized in that the free end of the attachment provided on the operating element is opposite the inclined surface at the free end of the bolt and, when the operating element is actuated, interacts with this inclined surface forming a drain frame. In this way it is achieved that the already inclined surface at the free end of the bolt forms a drain ramp with which the free end of the projection projecting from the operating element interacts, the pronounced oblique course of this surface resulting in an effective force component directed away from the housing, which Releasing the shaving head frame from its position held on the housing supports clearly noticeable, which gives the user who actuates the operating element, the feeling that the shaving head frame after the latch is released from the rest on the shaving head frame, so to speak. This results in a particular ease of use, since the operator does not have to simultaneously depress this button when operating the operating member and also has to tighten the shaving head frame relatively strongly.

Als vorteilhaft hinsichtlich des Zusammenwirkens des freien Endes des Ansatzes am Bedienungsorgan mit der schräg verlaufenden Fläche am freien Ende des Riegels hat sich erwiesen, wenn die schräg verlaufende Fläche am freien Ende des Riegels durch eine Keilfläche und der Ansatz am Bedienungsorgan durch eine quer zu dieser Keilfläche verlaufende Leiste gebildet ist.As advantageous in terms of the interaction of the free end of the approach at the operator Nungsorgan with the inclined surface at the free end of the bolt has been found if the inclined surface at the free end of the bolt is formed by a wedge surface and the approach to the control element by a strip extending transversely to this wedge surface.

Die Erfindung wird im folgenden anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargstellt ist, auf das sie jedoch nicht beschränkt sein soll, näher erläutert. Fig.1 zeigt einen Trockenrasierapparat in perspektivischer Ansicht. Fig.2 zeigt im Schnitt einen in Fig.1 mit der Linie II-11 gekennzeichneten Ausschnitt des Trockenrasierapparates nach Fig.1.The invention is explained in more detail below with reference to the drawing, in which an embodiment of the invention is shown, but to which it should not be limited. 1 shows a dry shaving apparatus in a perspective view. 2 shows in section a section of the dry shaving apparatus according to FIG. 1, identified by the line II-11 in FIG.

In den Figuren 1 und 2 ist mit 1 das Gehäuse eines Trockenrasierapparates bezeichnet, auf das ein Scherkopfrahmen 2 aufsetzbar ist, der ein Obermesser 3 trägt, welches im vorliegenden Fall als Siebscherfolie ausgebildet ist. Mit diesem Obermesser 3 wirkt ein Untermesser 4 zusammen, das als Lamellenmesser ausgebildet ist, welches in üblicher, hier aber nicht näher dargestellter Art und Weise federnd in die gewölbt verlaufende Siebscherfolie hineingedrückt und im Betrieb hin- und hergehend antreibbar ist. Dieser Antrieb erfolgt von einem Motor her, der im Gehäuse 1 untergebracht ist und abtriebsseitig mit dem Untermesser 4 zusammenwirkt. Der Scherkopfrahmen 2 ist mit mindestens einem aus einer Seitenwand 5 des Gehäuses 1 herausragenden, quer zu derselben entgegen der Wirkung einer Feder 6 verstellbaren Riegel 7 am Gehäuse 1 festgehalten, wobei er mit seinem freien Ende eine am Scherkopfrahmen 2 vorgesehene Rast 8 hintergreift. Zum Lösen des Scherkopfrahmens 2 vom Gehäuse 1 ist jedem Riegel 7 am Scherkopfrahmen 2 ein Bedienungsorgan 9 zugeordnet, das dem betreffenden Riegel 7 gegenüberliegt und entgegen der Wirkung einer Feder 10 von Hand aus in Richtung zum Riegel 7 hin verstellbar ist, wobei es mit dem freien Ende eines am Bedienungsorgan 9 vorgesehenen Ansatzes 11 mit dem freien Ende des Riegels 7 zusammenwirkt, um den Riegel 7 entgegen der Wirkung der Feder 6 so weit zu verstellen, bis dieser mit seinem freien Ende von der Rast 8 am Scherkopfrahmen 2 freikommt, wonach der Scherkopfrahmen 2 vom Gehäuse 1 lösbar ist.In FIGS. 1 and 2, 1 denotes the housing of a dry shaving apparatus onto which a shaving head frame 2 can be placed, which carries an upper knife 3, which in the present case is designed as a screen shaving foil. This upper knife 3 interacts with a lower knife 4, which is designed as a lamellar knife, which in the usual but not shown here is resiliently pressed into the curved sieve shear film and can be driven back and forth during operation. This drive takes place from a motor, which is accommodated in the housing 1 and cooperates with the lower knife 4 on the output side. The shaving head frame 2 is held on the housing 1 with at least one latch 7 projecting from a side wall 5 of the housing 1 and adjustable transversely thereto against the action of a spring 6, with its free end engaging behind a catch 8 provided on the shaving head frame 2. To release the shaving head frame 2 from the housing 1, each bolt 7 on the shaving head frame 2 is assigned an operating element 9, which is opposite the bolt 7 in question and, against the action of a spring 10, can be adjusted by hand in the direction of the bolt 7, with the free one End of a lug 11 provided on the control element 9 cooperates with the free end of the bolt 7 in order to adjust the bolt 7 against the action of the spring 6 until the free end of the catch 8 on the shaving head frame 2 frees it, after which the shaving head frame 2 is detachable from the housing 1.

Das aus der Seitenwand 5 des Gehäuses 1 herausragende freie Ende des Riegels 7 ist so ausgebildet, daß es eine schräg verlaufende Fläche 12 aufweist, die der durch den Pfeil 13 gekennzeichneten Aufsetzrichtung des Scherkopfrahmens 2 auf das Gehäuse 1 zugewandt ist und mit der sich in dieser Aufsetzrichtung vom Riegel 7 weg erstreckenden Seitenwand 5 des Gehäuses 1 einen spitzen Winkel bildet, der in Fig.2 durch den Doppelpfeil 14 angedeutet ist. Der dieser schräg verlaufenden Fläche 12 gegenüberliegende Abschnitt 15 des freien Endes des Riegels 7 wirkt dabei mit der Rast 8 am Scherkopfrahmen 2 zusammen, wodurch der Scherkopfrahmen 2 am Gehäuse 1 festgehalten wird. Im ganzen gesehen ist im vorliegenden Fall das freie Ende des Riegels 7 keilförmig ausgebildet, so daß die schräg verlaufende Fläche 12 durch eine Keilfläche gebildet ist. Selbstverständlich wären aber auch noch andere Ausbildungen des freien Endes des Riegels 7 möglich, soferne es eine im wesentlichen schräg verlaufende Fläche aufweist, die der Aufsetzrichtung des Scherkopfrahmens 2 auf das Gehäuse 1 zugewandt ist und mit der sich in dieser Aufsetzrichtung vom Riegel 7 weg erstreckenden Seitenwand 5 des Gehäuses 1 einen spitzen Winkel bildet.So könnte beispielsweise das freie Ende des Riegels 7 auch kegelförmig ausgebildet sein.The protruding from the side wall 5 of the housing 1 free end of the bolt 7 is formed so that it has an inclined surface 12 which faces the direction of attachment of the shaving head frame 2 to the housing 1 indicated by the arrow 13 and with which in this The mounting direction of the side wall 5 of the housing 1, which extends away from the bolt 7, forms an acute angle, which is indicated in FIG. 2 by the double arrow 14. The section 15 of the free end of the bolt 7 opposite this inclined surface 12 interacts with the catch 8 on the shaving head frame 2, whereby the shaving head frame 2 is held on the housing 1. Seen as a whole, in the present case the free end of the bolt 7 is wedge-shaped, so that the inclined surface 12 is formed by a wedge surface. Of course, however, other designs of the free end of the bolt 7 would also be possible, provided that it has a substantially obliquely extending surface which faces the direction in which the shaving head frame 2 is placed on the housing 1 and with the side wall which extends in this direction from the bolt 7 5 of the housing 1 forms an acute angle. For example, the free end of the bolt 7 could also be conical.

Die gegenseitige Anordnung des freien Endes des Riegels 7 und des Ansatzes 11 am Bedienungsorgan 9 ist nun so getroffen, daß das freie Ende des am Bedienungsorgan 9 vorgesehenen Ansatzes 11 der schräg verlaufenden Fläche 12 am freien Ende des Riegels 7 gegenüberliegt, so daß es bei Betätigung des Bedienungsorgans 9 mit dieser schräg verlaufenden Fläche 12 zusammenwirkt. Der Ansatz 11 am Bedienungsorgan 9 ist dabei als Leiste ausgebildet, die quer zur durch eine Keilfläche gebildeten schräg verlaufenden Fläche 12 am freien Ende des Riegels 7 verläuft, wodurch ein einwandfreies und sicheres Zusammenwirken des Ansatzes 11 mit der schräg verlaufenden Fläche 12 erhalten wird.The mutual arrangement of the free end of the bolt 7 and the approach 11 on the operating member 9 is now such that the free end of the provided on the operating member 9 approach 11 of the inclined surface 12 at the free end of the bolt 7, so that it is actuated of the operating element 9 cooperates with this inclined surface 12. The approach 11 on the operating member 9 is designed as a bar that extends transversely to the inclined surface 12 formed by a wedge surface at the free end of the bolt 7, whereby a perfect and safe interaction of the approach 11 with the inclined surface 12 is obtained.

Durch eine derartige gegenseitige Anordnung des Ansatzes 11 am Bedienungsorgan 9 und der schräg verlaufenden Fläche 12 am freien Ende des Riegels 7 wird erreicht, daß die schräg verlaufende Fläche 12 für den Ansatz 11 am Bedienungsorgan 9 und damit für den gesamten Scherkopfrahmen 2 eine Ablauframpe bildet, an der bei Betätigung des Bedienungsorgans 9 durch das Zusammenwirken des freien Endes des Ansatzes 11 mit dieser schräg verlaufenden Fläche 12 am freien Ende des Riegels 7 eine Kraftkomponente entsteht, die senkrecht zur Betätigungsrichtung des Bedienungsorgans 9 vom Gehäuse 1 weg gerichtet ist. Eine solche Kraftkomponente ist bestrebt, den Scherkopfrahmen 2 vom Gehäuse 1 zu lösen, wodurch die Kraft, die von Hand aus aufzubringen ist, um das Lösen des Scherkopfrahmens 2 vom Gehäuse 1 zu bewirken, um diese Kraftkomponente verringert wird. Für die Bedienungsperson, die den Scherkopfrahmen 2 vom Gehäuse 1 des Trockenrasierapparates lösen möchte, ergibt sich damit der Eindruck eines besonders leichtgängigen Lösens ohne besonderer Kraftanstrengung, was als sehr bedienungsfreundlich empfunden wird.Such mutual arrangement of the extension 11 on the operating member 9 and the inclined surface 12 at the free end of the bolt 7 ensures that the inclined surface 12 forms a discharge ramp for the extension 11 on the operating member 9 and thus for the entire shaving head frame 2, on which, when the operating member 9 is actuated by the interaction of the free end of the projection 11 with this inclined surface 12 at the free end of the bolt 7, a force component is created which is directed away from the housing 1 perpendicular to the operating direction of the operating member 9. Such a force component tends to detach the shaving head frame 2 from the housing 1, whereby the force that has to be applied by hand to bring about the detachment of the shaving head frame 2 from the housing 1 is reduced by this force component. For the operator who wants to detach the shaving head frame 2 from the housing 1 of the dry shaving apparatus, this gives the impression of a particularly smooth release without any particular effort, which is perceived as very user-friendly.

Dadurch, daß die eine Ablauframpe bildende, schräg verlaufende Fläche 12 am freien Ende des Reigels 7 vorgesehen ist, unterliegt die Wahl ihrer Neigung keinen wesentlichen konstruktiven Bechränkungen, da für die Verriegelung des Scherkopfrahmens 2 am Gehäuse 1 an sich stets ein gewisser Platz für das freie Ende des Riegels 7 zwischen der diesen Riegel 7 aufweisenden Gehäusewand 5 und dem Scherkopfrahmen 2 zur Verfügung stehen muß, der dann auch praktisch vollständig für die Bildung einer Ablauframpe mit der gewünschten Neigung ausgenützt werden kann.Der spitze Winkel, den diese schräg verlaufende Fläche 12, mit der sich in der Aufsetzrichtung des Scherkopfrahmens 2 auf das Gehäuse 1 vom Riegel 7 weg erstreckenden Seitenwand 5 des Gehäuses 1 bildet, kann daher so dimensioniert werden, daß die Ablauframpe ihre Funktion optimal erfüllt. Diesbezüglich hat sich in der Praxis ein spitzer Winkel in der Größenordnung von 30 als sehr günstig erwiesen.Characterized in that the inclined surface 12 forming a discharge ramp at the free end of the Reigels 7 is provided, the choice of their inclination is not subject to any significant design restrictions, since for the locking of the shaving head frame 2 on the housing 1, there is always a certain space for the free end of the bolt 7 between the housing wall 5 having this bolt 7 and the shaving head frame 2 must be available, which can then be used practically completely for the formation of a drain ramp with the desired inclination. The acute angle that this inclined surface 12, with which in the mounting direction of the shaving head frame 2 onto the housing 1 from the bolt 7 forms away extending side wall 5 of the housing 1, can therefore be dimensioned so that the discharge ramp fulfills its function optimally. In this regard, an acute angle on the order of 30 has proven to be very favorable in practice.

Beim vorliegenden Ausführungsbeispiel ist das Bedienungsorgan 9 verschiebbar ausgebildet. Es wäre aber auch ohne weiteres möglich, ein verschwenkbares Bedienungsorgan vorzusehen. Auch für die Ausbildung des Ansatzes 11 am Bedienungsorgan 9 bestehen verschiedene Möglichkeiten. So könnte anstelle einer Leiste der Ansatz 11 beispielsweise auch als Stift, Nase oder dergleichen ausgebildet sein, soferne sein Zusammenwirken mit der eine Ablauframpe bildenden, schräg verlaufenden Fläche am freien Ende des Riegels 7 gewährleistet ist. Hinsichtlich der Art und Weise des Festhaltens des Scherkopfrahmens am Gehäuse und seinem Lösen von demselben bestehen ebenfalls verschiedene Möglichkeiten, dies auch unter Ausnützung der leichteren Lösbarkeit des Scherkopfrahmens vom Gehäuse. So kann der Scherkopfrahmen vom Gehäuse abziehbar oder wegschwenkbar sein. Im erstgenannten Fall werden dann zweckmäßigerweise zwei Riegel an einander gegenüberliegenden Seitenwänden des Gehäuses vorgesehen, ebenso wie zwei Bedienungsorgane am Scherkopfrahmen zum Verstellen der Riegel. Im zweitgenannten Fall kann nur ein Riegel an einer Seitenwand des Gehäuses und ein diesem zugeordnetes Bedienungsorgan am Scherkopfrahmen vorgesehen sein, wobei dann an der gegenüberliegenden Seitenwand des Gehäuses die Halterung des Scherkopfrahmens scharnierartig ausgebildet wird.In the present embodiment, the control member 9 is slidable. But it would also be easily possible to provide a pivotable control element. There are also various possibilities for the formation of the approach 11 on the control element 9. For example, instead of a bar, the extension 11 could also be designed as a pin, nose or the like, provided that its interaction with the sloping surface forming a discharge ramp at the free end of the bolt 7 is ensured. With regard to the manner of holding the shaving head frame on the housing and its release from the same, there are also various possibilities, this also taking advantage of the easier releasability of the shaving head frame from the housing. For example, the shaving head frame can be removed from the housing or pivoted away. In the former case, two bolts are then expediently provided on opposite side walls of the housing, as are two operating elements on the shaving head frame for adjusting the bolts. In the second-mentioned case, only one latch can be provided on one side wall of the housing and an operating element assigned to it on the shaving head frame, the holder of the shaving head frame then being designed in a hinge-like manner on the opposite side wall of the housing.

Claims (2)

1. A dry-shaving apparatus comprising a housing (1) and a shaving-head frame (2) which can be mounted on said housing and which carries an upper shaving member (3), which shaving-head frame is secured to the housing by means of at least one latch (7) which projects from a side wall (5) of the housing, which is movable transversely of said wall against the action of a spring (6) and whose free end has a substantially inclined surface (12) which faces in the direction in which the shaving-head frame is mounted on the housing and which extends at an acute angle to the relevant side wall (5) of the housing, which wall extends from the latch (7) in said mounting direction, the latch engaging behind a detent (8) on the shaving-head frame with a free-end portion which is remote from its inclined surface (12), and which, to disengage the latch from the detent, comprises an actuating member (9) which faces the latch and which is movable by hand towards the latch, which actuating member comprises a projection (11) which extends towards the latch and whose free end cooperates with the free end of the latch upon actuation of the actuating member (9), the latch being moved against the action of the spring (6) and the shaving-head frame being detachable from the housing after disengagement of the latch from the detent on the shaving-head frame, characterized in that the free end of the projection (11) on the actuating member (9) is arranged opposite the inclined surface (12) on the free end of the latch and during actuation of the actuating member cooperates with said inclined surface which constitutes a run-off surface.
2. A dry-shaving apparatus as claimed in Claim 1, characterized in that the inclined surface (12) on the free end of the latch is constituted by a wedge surface and the projection on the actuating member is constituted by a rib which extends transversely of said wedae surface.
