Abstract

In a hair cutting apparatus, particularly an electric hair cutting apparatus, with a shearing head comprised of a shear plate and a cutting element as well as with a spacer comb adapted to be seated on the shearing head for sliding contact with the skin surface to be treated, with the position of the forward edge of the cutting element being adjustable relative to the skin surface, the spacer comb (3)-upon being seated on the shearing head (2) of the hair cutting apparatus (1)-is adapted to be coupled with the hair cutting apparatus by centrally controlled coupling members (10, 14, 23) cooperating with coupling members (16, 18, 24) of the comb to provide a coupling (13) between the body (7) of the hair cutting apparatus (1) and the spacer comb (3), the coupling members being adapted to move the said spacer comb into its individual ratchet positions producing different lengths of the cut. The coupling members (10, 14, 23) providing for coupling and uncoupling of the spacer comb 3 are controlled by a slide control (11) of the body (7) of the hair cutting apparatus (1) in which all functions of the hair cutting apparatus including enabling and disabling of the drive are incorporated.

Description

Die Erfindung betrifft eine Haarschneidemaschine, insbesondere eine elektrische Haarschneidemaschine, mit einem Scherkopf, bestehend aus einer Scherkammplatte und einem Schermesser sowie mit einem auf den Scherkopf aufsetzbaren Distanzkamm zur gleitenden Auflage auf der zu behandelnden Hautoberfläche, wobei die Postition der Vorderkante des Schermessers zur Hautoberfläche einstellbar ist, und einem Schiebeschalter zum Ein- und Auschalten des Antriebes der Haarschneidemaschine (siehe DE-A-3441 060).The invention relates to a hair clipper, in particular an electric hair clipper, with a shaving head, consisting of a shaving comb plate and a shaving knife, and with a spacing comb which can be placed on the shaving head for sliding contact on the skin surface to be treated, the position of the front edge of the shaving knife to the skin surface being adjustable , and a slide switch for switching the drive of the hair clipper on and off (see DE-A-3441 060).

Bei derartigen Haarschneidemaschinen ist der ihr zugehörige Distanzkamm bei Gebrauch von Hand auf den Scherkopf der Maschine durch einfaches Aufstecken aufsetzbar. Der so auf den Scherkopf der Haarschneidemaschine aufgesetzte Distanzkamm wird dabei durch eine mit einer Rastnase des Scherkopfes zusammenwirkende Rastfeder an der Haarschneidemaschine funktionsgerecht festgelegt. Zum Erzielen unterschiedlicher Schnittlängen während des Haarschnitts ist es jedoch unerläßlich, den Distanzkamm in unterschiedlichen Abständen von der Vorder- bzw. Schneidkante des eine gerätefeste Scherkammplatte und ein mit dieser zusammenwirkendes, oszillierendes Schermesser umfassenden Scherkopfes zu positionieren. Dise Möglichkeit des Festlegens des Distanzkammes in den Abstand der Gleitebene seiner zahnförmigen Stützen auf der zu behandelnden Hautoberfläche zur Vorder- bzw. Schneidkante des Scherkopfes bzw. des ihm zugehörigen Schermessers der Haarschneidemaschine ist bei bekannten und zum Teil marktüblichen Haarschneidemaschinen gegeben durch der oder den Außenseiten des Scherkopfgehäuses angeformte, einander parallele Rastenleisten, die mit hebelartigen Rastgliedern an oder in den Seitenwandungen des Distanzkammes als Rastgesperre zusammenwirken. Diese Haarschneidemaschinen erlauben zwar ein axiales Versetzen des auf den Scherkopf aufgesetzten Distanzkammes zum Verändern seiner Raststellung entsprechend der gewünschten Schnittlänge für den zu schneidenden Berreich an der Hautoberfläche. Jedoch ist ein solches Rastgesperre an der Außenwandung des stets von der Hand des Benutzers umgriffenen Körpers der Haarschneidemaschine beträchtlichem Verschleiß unterworfen, der insbesondere daraus resultiert, daß bei jedem Aufsetzen des Distanzkammes auf den Scherkopf zumindest eine, meist jedoch mehrere oder alle der im Bereich des Scherkopfes vorgesehenen, nach außen ragenden schwergängigen Rastnioppen von den nach innen ragenden Rastgliedern des Distanzkammes überfahren und dabei von diesen reibungsschlüssig in Anspruch genommen werden. Die Rastnoppen am Scherkopfgehäuse werden hierbei durch die scharfen Kanten der diesen Rastgliedern zugeordneten Rastzähne schon nach relativ kurzzeitigem Gebrauch abgeschabt bzw. abgeschliffen, womit ein exaktes Positionieren des Distanzkammes auf dem Scherkopf nicht mehr möglich ist.In such hair clippers, the associated spacing comb can be placed on the shaving head of the machine by simply plugging it on when used by hand. The spacer comb placed on the shaving head of the hair clipper in this way is functionally fixed on the hair clipper by a detent spring which interacts with a locking lug of the shaving head. To achieve different cut lengths during the haircut, however, it is indispensable to position the spacer comb at different distances from the front or cutting edge of a shaving comb plate that is fixed to the device and a shaving head that interacts with the oscillating shaving knife. This possibility of setting the distance comb in the distance of the sliding plane of its tooth-shaped supports on the skin surface to be treated to the front or cutting edge of the shaving head or the associated shaving knife of the hair clipper is given in known and partly commercially available hair clippers by the or the outside of the Shaving head housing integrally formed, mutually parallel notch strips, which interact with lever-like locking members on or in the side walls of the spacer comb as a locking mechanism. These hair clippers allow an axial displacement of the spacing comb placed on the shaving head in order to change its locking position in accordance with the desired cutting length for the area to be cut on the skin surface. However, such a locking mechanism on the outer wall of the body of the hair clipper, which is always gripped by the hand of the user, is subject to considerable wear and tear, which results in particular from the fact that each time the distance comb is placed on the shaving head, at least one, but usually several or all, of the area in the area of the shaving head provided, outwardly projecting stiff locking knobs run over by the inwardly projecting locking members of the spacer comb and are used by these frictionally. The locking knobs on the shaving head housing are scraped off or ground off after relatively short use by the sharp edges of the locking teeth assigned to these locking members, so that an exact positioning of the distance comb on the shaving head is no longer possible.

Ein weiterer Mangel einer solchen Festlegung des Distanzkammes auf dem Scherkopf der Haarschneidemaschine besteht darin, daß zum Ändern der Schnittlänge der Distanzkamm mit zwei gespreizten Fingern der nicht die Haarschneidemaschine haltenden Hand erfaßt und so dann - je nach gewünschter Schnittlänge - in Abzugsrichtung oder in Aufschubrichtung bis zum Einrasten seines Rastgliedes in die der gewäglten Räststellung entsprechenden Rastnut am Gerätegehäuse gegenüber diesem verschoben werden muß. Dieser Vorgang erfordert das Absetzen der Haarschneidemaschine aus ihrer Gebrauchsstellung und ihr anschließendes Erfassen mit einer Hand, damit die andere Hand unter genauer Beobachtung der Haarschneidemaschine und des Distanzkammes das Verstellen desselben am Scherkopf vollziehen kann.Another deficiency of such a definition of the distance comb on the shaving head of the hair clipper is that to change the cutting length of the distance comb is grasped with two fingers of the hand not holding the hair clipper and then - depending on the desired length of cut - in the pull-off direction or in the direction of extension until Locking its locking member in the locking groove corresponding to the selected locking position on the device housing must be moved relative to this. This process requires the hair clipper to be removed from its position of use and then grasped with one hand so that the other hand can adjust the shaving head while closely observing the hair clipper and the distance comb.

Aufgabe der Erfindung ist es, eine Haarschneidemaschine der eingangs genannten Art zu schaffen, bei der sowohl die Verstellung des Distanzkammes in unterschiedliche Schnittlängen bewirkende Gebrauchs- bzw. Raststellungen als auch die Halterung des Distanzkammes im aufgeschobenen Zustand auf der Haarschneidemaschine sowie die Ein- und Ausschaltung des elektrischen Haarschneideantriebes mittels eines einzigen Betätigungselementes zu bewerkstelligen ist.The object of the invention is to provide a hair clipper of the type mentioned, in which both the adjustment of the distance comb in different cutting lengths effecting use or locking positions as well as the mounting of the distance comb in the pushed state on the hair clipper and the switching on and off of electric hair clipper drive can be accomplished by means of a single actuating element.

Gelöst wird diese Aufgabe bei der im Oberbegriff des Anspruchs 1 angegebenen Haarschneidemaschine nach der Erfindung dadurch, daß der Distanzkamm und der Schiebeschalter mit in Eingriff bringbaren Kupplungsmitteln versehen sind, daß zu der Ein- und Ausschaltstellung des Schiebeschalters weitere Raststellungen für den Distanzkamm vorgesehen sind und daß in den Rastpositionen die im Eingriff befindlichen Kupplungsmittel des Distanzkammes und des Schiebeschalters mittels einer Sperre gegen Entkuppeln gesichert sind.This object is achieved in the hair clipper according to the invention specified in the preamble of claim 1 in that the distance comb and the slide switch are provided with coupling means which can be brought into engagement, that further locking positions for the distance comb are provided for the on and off position of the slide switch and that in the locking positions, the engaged coupling means of the distance comb and the slide switch are secured against decoupling by means of a lock.

Diese erfindungsgemäße Lösung ermöglicht die Bedienung der Haarschneidemaschine, das heißt sowohl das Ein- und Ausschalten als auch die Einstellung der verschiedenen Rastpositionen des Distanzkammes, mittels einer einzigen Schalthandhabe. Das umständliche Ergreifen des Distanzkammes am Scherkopf zur Einstellung der verschiedenen Rastpositionen wird damit vermieden.This solution according to the invention enables the hair clipper to be operated, that is to say both the switching on and off and the setting of the various latching positions of the distance comb, by means of a single switching handle. The cumbersome grasping of the spacer comb on the shaving head for setting the various locking positions is thus avoided.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Advantageous refinements are described in the subclaims.

Wie die Fig. 1 bis 4 erkennen lassen, besteht die Haarschneidemaschine 1 gemäß der Erfindung im wesentlichen aus einem schmalen, haptisch gestalteten Körper, dem ein Scherkopf 2 zugehört, der in den Fig. 1 und 2 durch einen auf den Scherkopf 2 aufgesetzten Distanzkamm 3 überdeckt ist. Der Distanzkamm 3 hat die Aufgabe, die Vorderkante 4 des aus einer festen Scherkammplatte 5 und einem auf diesem hin- und hergleitenden Schermessers 6 gebildeten Scherkopfes 2 in vorbestimmtem Abstand zur jeweils zu behandelnden Hautoberfläche, beispielsweise der Kopfhaut einer zu frisierenden Person, zu halten, wobei der Distanzkamm - wie noch später erläutert - in unterschiedlichen Hubstellungen gegenüber dem Körper 7 der Haarschneidemaschine 1 an deren Scherkopf positionierbar ist.As can be seen from FIGS. 1 to 4, the hair clipper 1 according to the invention essentially consists of a narrow, haptically designed body, to which a shaving head 2 belongs, which in FIGS. 1 and 2 has a spacing comb 3 placed on the shaving head 2 is covered. The spacing comb 3 has the task of keeping the front edge 4 of the shaving head plate 2, which is formed from a fixed shaving comb plate 5 and a shaving blade 6 which reciprocates thereon, at a predetermined distance from the skin surface to be treated, for example the scalp of a person to be styled, whereby the distance comb - as explained later - can be positioned in different stroke positions with respect to the body 7 of the hair clipper 1 on the shaving head.

Der Distanzkamm 3 umfaßt als Hohlkörper den Körper 7 der Haarschneidemaschine 1 im Bereich seines Scherkopfes 2 an allen vier Seiten, wobei seine ihm angeformten zahnförmigen Stützen 8 den zu schneidenden Haaren der zu behandelnden Person den Durchtritt zum Scherkopf 2 gestatten, von dessen Schermesser 6 sie dann abgeschnitten werden. Die hierbei verbleibende Länge der abgeschnittenen Haare entspricht - bei auf die Hautoberfläche aufgesetzten Stützen 8 - dem Abstand der Vorderkante der zahnförmigen Stützen 8 von der Vorder- oder Schneidkante des Scherkopfes bzw. des ihm zugehörigen Schermessers, wobei dieser Abstand - wie bereits erwähnt - bei der Haarschneidemaschine veränderbar ist.The spacer comb 3 comprises, as a hollow body, the body 7 of the hair clipper 1 in the area of its shaving head 2 on all four sides, its tooth-shaped supports 8 which are formed on it allowing the hair of the person to be treated to pass through to the shaving head 2, from whose shaving knife 6 they are then cut be cut off. The remaining length of the cut hair corresponds - in the case of supports 8 placed on the skin surface - to the distance of the front edge of the tooth-shaped supports 8 from the front or cutting edge of the shaving head or of the associated shaving knife, this distance - as already mentioned - in the case of Hair clipper is changeable.

Zum funktionsgerechten Gebrauch der Haarschneidemaschine unter Verwendung des die zu schneidende Haarlänge bestimmenden Distanzkammes sind letzterem Kupplungsmitel zugeordnet, die mit geeigneten Kupplungsgliedem des Körpers 7 der Haarschneidemaschine zusammenwirken.For functional use of the hair clipper using the distance comb determining the hair length to be cut, the latter are assigned coupling means which interact with suitable coupling members of the body 7 of the hair clipper.

Wie insbesondere die Fig. 4 und 5 zeigen, ist hierzu der Haarschneidemaschine 1 ein Kupplungsstößel 10 zugeordnet, der in einer gehäuseseitigen Führung 9 mit T-förmigen Querschnitt in Richtung der Längsachse x der Haarschneidemaschine 1 gleitbar ist. Diesem Kupplungsstößel 10 ist ein Schiebeschalter 11 zugeordnet, der sich über die gesamte Breite der Haarschneidemaschine 1 ersteckt und damit ein sicheres Bedienen sowohl mit der linken als auch mit der rechten Hand des Gerätebenutzers, also eine Einhandbedienung zuläßt. Der Schiebeschalter 11 erfüllt mehrere Funktionen, nämlich zunächst diejenige, den elektrischen oder mechanischen Antrieb der Haarschneidemaschine ein- oder auszuschalten, sodann. die weitere Funktion, den Distanzkamm 3 mit der Haarschneidemaschine funktionsgerecht zu kuppeln bzw. zu entkuppeln, und schließlich die Funktion, den angekuppelten Distanzkamm in jeweils andere Distanzen bewirkende Gebrauchsstellungen zu überführen.4 and 5 show in particular that the hair clipper 1 is assigned a coupling plunger 10 which can be slid in a housing-side guide 9 with a T-shaped cross section in the direction of the longitudinal axis x of the hair clipper 1. This coupling plunger 10 is assigned a slide switch 11 which extends over the entire width of the hair clipper 1 and thus permits safe operation with both the left and right hand of the device user, that is to say one-hand operation. The slide switch 11 fulfills several functions, namely first of all switching the electrical or mechanical drive of the hair clipper on or off, then. the further function of coupling or uncoupling the distance comb 3 with the hair clipper in a functionally appropriate manner, and finally the function of converting the coupled distance comb into positions of use which cause different distances.

Die Funktion des mittels Schiebeschalters 11 innerhalb und unterhalb der Frontwandung 12 der Haarschneidemaschine 1 längs verschiebbaren Kupplungsstößels 10 im Zusammenwirken mit dem Kupplungsmittel des Distanzkammes 3 zeigen - in mehreren Kupplungsphasen - die Fig. 5 bis 10.The function of the coupling plunger 10, which can be displaced longitudinally by means of a slide switch 11 inside and below the front wall 12 of the hair clipper 1, in cooperation with the coupling means of the distance comb 3 is shown in several coupling phases by FIGS. 5 to 10.

Die Fig. 5 zeigt hierbei die grundsätzliche Wirkungsweise der Kupplung 13 zwischen dem hier dem Kupplungsstößel 10 zugeordneten Schiebeschalter 11 der Haarschneidemaschine 1 und dem auf den Scherkopf 2 des Körpers 7 der Haarschneidemaschine aufsetzbaren Distanzkamm 3.5 shows the basic mode of operation of the coupling 13 between the slide switch 11 of the hair clipper 1 assigned here to the clutch plunger 10 and the spacing comb 3 which can be placed on the shaving head 2 of the body 7 of the hair clipper.

Wie ersichtlich, ist dem mit dem Schiebeschalter 11 verbundenen Kupplungsstößel 10 eine Kupplungsnase 14 angeformt, die um die Achse eines dem Stößel 10 angeformten Filmscharniers 15 schwenkbar ist, und zwar derart, daß die Kupplungsnase 14 nach jedem Verschwenken selbsttätig wieder in ihre Ausgangsstellung gemäß Fig. 5 zurückkehrt.As can be seen, the coupling plunger 10 connected to the slide switch 11 is formed with a coupling lug 14 which can be pivoted about the axis of a film hinge 15 molded onto the plunger 10, in such a way that the coupling lug 14 automatically returns to its starting position after each pivoting in accordance with FIG. 5 returns.

Der den Scherkopf 2 der Haarschneidemaschine 1 umgebende, aufgesetzte Distanzkamm 3 ist im Bereich seiner als Kupplungsmittel dienenden Wandung 16 eine den Stößel 10 einschließlich seiner Kupplungsnase 14 aufnehmende Kupplungsnut 17 zugeordnet. Diese Kupplungsnut 17 umfaßt eine der Kupplungswandung 16 des Distanzkammes 3 angeformte Schulter 18, die von der Kupplungsnase 14 des Kupplungsstößels 10 durch Ausweichen in die von einer Wandung 19 der Haarschneidemaschine 1 gebildeten Vertiefung 20 im Bereich der Kupplungsnut 17 während des Aufsetzens des Distanzkammes 3 überwunden wird.The attached spacer comb 3 surrounding the shaving head 2 of the hair clipper 1 is assigned, in the region of its wall 16 serving as a coupling means, a coupling groove 17 which receives the plunger 10 including its coupling lug 14. This coupling groove 17 comprises a shoulder 18 integrally formed on the coupling wall 16 of the spacer comb 3, which is overcome by the coupling nose 14 of the coupling tappet 10 by deflecting into the depression 20 formed by a wall 19 of the hair clipper 1 in the region of the coupling groove 17 during the placement of the spacing comb 3 .

Der aufgesetzte Distanzkamm 3 wird sonach von der seine Sperrschulter 18 hintergreifenden Kupplungsnase 14 des Stößels 10 gehalten und damit gegen ungewolltes Lösen von der Haarschneidemaschine gesichert. In dieser Aufsetzstellung der so miteinander in Verbindung gebrachten Kupplungsglieder 10, 14 der Haarschneidemaschine 1 und den Kupplungsmitteln 16, 17, 18 des Distanzkammes 3 befindet sich der auch auf elektrische Schaltmittel 21 für den Antrieb einwirkende Schiebeschalter noch in der « Null » bzw. Aus-Stellung, in der der Speisestromkreis der Haarschneidemaschine geöffnet ist. Durch anschließendes Verschieben des Schiebeschalters 11 und damit auch des Kupplungsstößels 10 in Richtung der Achse x der Haarschneidemaschine 1 - gleich Hubrichtung x des Distanzkammes 3 - von der in Fig.5 dargestellten Position « Aus » in die daran gestrichelt Position « Ein » betätigt der Schiebeschalter 11 die Schaltmittel 21, wodurch der Speisestromkreis der Haarschneidemaschine 1 geschlossen und damit deren nicht dargestellter Antrieb eingeschaltet ist.The spacer comb 3 is thus held by the coupling lug 14 of the plunger 10 engaging behind its locking shoulder 18 and thus secured against unintentional detachment from the hair clipper. In this mounting position of the coupling members 10, 14 of the hair clipper 1 and the coupling means 16, 17, 18 of the distance comb 3, the slide switch, which also acts on electrical switching means 21 for the drive, is still in the “zero” or off position, in which the feed circuit of the hair clipper is open. By subsequently sliding the slide switch 11 and thus also the coupling plunger 10 in the direction of the axis x of the hair clipper 1 - same as the stroke direction x of the spacing comb 3 - from the position “Off” shown in FIG 11, the switching means 21, whereby the feed circuit of the hair clipper 1 is closed and thus the drive, not shown, is switched on.

In dieser « Ein » Position gelangt die Vorderwand 23 des Kupplungsstößels 10 an eine der Kupplungswandung 16 des Distanzkammes 3 angeformte Schulter 24, während die der Kupplungsnase (gemäß Fig. 5) abgewandte Seitenwand 25 an der Außenwandung 26 einer durch die Gehäusewandung 19 der Haarschneidemaschine 1 und durch die Kupplungswandung 16 des Distanzkammes 3 gebildeten Zwangsführung 27 gleitend zur Anlage kommt. Damit ist in der « Ein Position des Schiebeschalters 11 der Kupplungsstößel 10 durch die Zwangsführung 27 an einem elastischen Ausweichen vor der Schulter 24 gehindert. Die das Ausweichen erleichternde Schrägkante 28 des Kupplungsstößels 10, der beim Aufsetzen des Distanzkammes 3 mit der Schrägkante 29 der Rastschulter 18 der kammseitigen Kupplungswandung 16 zusammenwirkt, kommt sonach hier nicht zur Wirkung.In this “on” position, the front wall 23 of the coupling plunger 10 arrives at a shoulder 24 integrally formed on the coupling wall 16 of the spacing comb 3, while the side wall 25 facing away from the coupling nose (according to FIG. 5) on the outer wall 26 of a through the housing wall 19 of the hair clipper 1 and formed by the coupling wall 16 of the spacer 3 positive guide 27 slidably comes to rest. Thus, in the one position of the slide switch 11, the clutch plunger 10 is prevented from elastically evading in front of the shoulder 24 by the positive guide 27. The sloping edge 28 of the coupling plunger 10, which facilitates the evasion, and which cooperates with the sloping edge 29 of the locking shoulder 18 of the coupling-side coupling wall 16 when the spacing comb 3 is placed on, does not come into effect here.

Die Fig. 6 zeigt in einer schematisierten Frontansicht ein sowohl den Kupplungsstößel 10 als auch den Schiebeschalter 11 umfassenden, vertikal verschiebliches Griffstück 30, das der Haarschneidemaschine 1 als Zentralschalter dient. Dem Griffstück 30 ist hier ein um ein eingeformtes Filmscharnier 31 schwenkender Rasthebel 32 angeformt, dessen Rastnase 33 unter Eigenfederung in Rastkerben einer gerätefest angeordneten Rastenleiste 34 der Haarschneidemaschine 1 eingreift und mit diesen je ein Rastgesperre bildet. Der Eingriff der Rastnase 33 in die (gemäß Fig. 6) unterste Rastkerbe 34.1 bestimmt die « Null »- bzw. « Ausschalt »-Stellung des Schiebeschalters 11. Wird der Schiebeschalter 11 um eine Rastteilung nach oben geschoben, so gelangt die Rast- . nase 33 in die Rastkerbe 34.2, welche die Einschaltstellung des Schiebeschalters 11 bestimmt. Der Kupplungsstößel 10 gelangt hierbei aus seiner nach Überwindung der Rastschulter 18 eingenommenen « Aus »-Stellung in die « Ein »-Stellung, in der seine Kupplungsnase 14 an der Sperrschulter 24 und der Innenwandung 26 der Zwangsführung 27 zur Anlage kommt und damit die Kupplung der Haarschneidemaschine 1 mit dem Distanzkamm 3 zum Zwecke der Positionierung des Distanzkammes vollzogen ist.6 shows a schematic front view of a vertically displaceable grip piece 30, which includes both the clutch plunger 10 and the slide switch 11, and which serves for the hair clipper 1 as a central switch. The grip piece 30 is formed here with a detent lever 32 pivoting about a molded-in film hinge 31, the detent 33 of which engages in detent notches of a detent bar 34 of the hair clipper 1 which is fixed to the device and forms a detent mechanism with each. The engagement of the latching lug 33 in the lowest latching notch 34.1 (according to FIG. 6) determines the “zero” or “switch-off” position of the slide switch 11. If the slide switch 11 is pushed up by one latching division, the latching. nose 33 in the notch 34.2, which determines the switch-on position of the slide switch 11. The clutch plunger 10 arrives from its "off" position, which it has assumed after overcoming the locking shoulder 18, into the "on" position, in which its coupling lug 14 comes to rest on the locking shoulder 24 and the inner wall 26 of the positive guide 27 and thus the coupling of the Hair clipper 1 with the spacer comb 3 for the purpose of positioning the spacer comb is completed.

Durch weiteres Verschieben des Schiebeschalters 11 in Richtung x (Fig. 5) um eine weitere Raststellung gelangt die Rastnase 33 in die Rastkerbe 34.3. Hierbei wird durch den in Richtung x mitbewegten Kupplungsstößel 10 der Distanzkamm 3 infolge der Anlage der stößelseitigen Vorderwand 23 an der Sperrschulter 24 der Kupplungswandung 16 in seine erste Raststellung geschoben. Diese erste Raststellung bewirkt das Schneiden der vom Distanzkamm erfaßten Haare mit relativ geringer Schnittlänge. Die Raststellung wird hier von einer dem Scherkopf 2 der Haarschneidemaschine 1 zugehörigen Markierungsskala 35, deren Ziffern « 1 bis « 4 in einem Ausschnitt 36 zwischen und unterhalb zweier benachbarter zahnförmiger Stützen 8 des Distanzkammes 3 sichtbar werden, angezeigt. Eine der Frontseite des Distanzkammes 3 zugeordnete Marke 37 zeigt dabei die jeweils Raststellung - hier die geringstmögliche Raststellung « 1 » ― des Distanzkammes 3 an.By further sliding the slide switch 11 in the direction x (FIG. 5) by a further latching position, the latching nose 33 arrives in the latching notch 34.3. Here, the spacer comb 3 is pushed into its first detent position by the coupling tappet 10 moving in the direction x as a result of the abutment of the tappet-side front wall 23 on the locking shoulder 24 of the coupling wall 16. This first latching position causes the hair that is caught by the spacer comb to be cut with a relatively short cutting length. The latching position is indicated here by a marking scale 35 associated with the shaving head 2 of the hair clipper 1, the numbers 1 to 4 of which are visible in a cutout 36 between and below two adjacent tooth-shaped supports 8 of the distance comb 3. A mark 37 assigned to the front of the distance comb 3 indicates the respective locking position - here the lowest possible locking position «1» - of the distance comb 3.

In gleicher Weise gelangt durch weiteres Nach-Oben-Schieben des Kupplungsstößels 10 mittels des ihm zugeordneten Schiebeschalters 11 der Distanzkamm 3 in weitere, den Abstand zwischen Scherkopf 2 und Distanzkamm 3 vergrößernde Raststellungen, die durch Einfallen der Rastnase 33 in die Rastkerben 34.4, 34.5 und 34.6 gekennzeichnet und anhand der Markierungsskala 35 durch die mittels Skalenziffem « 1 », « 2 », « 3 », « 4 » korrespondierende Marke 37 bzw. durch Ablesen der in Schieberichtung liegenden untersten, vom Distanzkamm nicht abgedeckten Skalenziffer angezeigt sind.In the same way, by pushing the clutch plunger 10 further upwards by means of the slide switch 11 assigned to it, the spacing comb 3 reaches further detent positions which increase the distance between the shaving head 2 and the spacing comb 3, which by engaging the detent 33 into the notches 34.4, 34.5 and 34.6 and are indicated on the basis of the marking scale 35 by the mark 37 corresponding to the scale numbers “1”, “2”, “3”, “4” or by reading off the lowest scale number lying in the sliding direction and not covered by the distance comb.

Das Zurückfahren des Distanzkammes 3 - beispielsweise zum Umschalten der Haarschneidemaschine auf eine kürzere Schnittlänge - erfolgt in einfacher Weise durch Zurückschieben des Schiebeschalters 11 in der der Pfeilrichtung x entgegengesetzten Richtung. Hierbei wird der Kupplungsstößel 10 in gleicher Schubrichtung bewegt und durch Einwirkung der Zwangsführung 27 die Kupplungswandung 16 des Distanzkammes 3 infolge der Anlage der stößelseitigen Schrägkante 38 an der mit dieser korrespondierenden Schrägkante 39 der Kupplungswandung 16 bis in die die geringste Schnittlänge bewirkende Raststellung « 1 » mitgenommen, die durch Einfallen der Rastnase 33 in die Rastkerbe 34.3 gekennzeichnet ist. Beim weiteren Zurückschieben des Kupplungsstößels 10 mittels des Schiebeschalters 11 entgegen der Pfeilrichtung x gelangt die Kupplungsnase 14 des Stößels 10 nach Passieren der Sperrkante 40, die sich gemäß Fig. 5 etwas unterhalb der Ebene der von der Kupplungswandung 16 gebildeten Sperrschulter 24 erstreckt, also in Kupplungsrichtung x gegenüber letzterer um ein geringes Maß vorspringt, in den Bereich der Kupplungsnut 17, die ein Ausweichen der an der kammseitigen Rastschulter 18 anliegenden Kupplungsnase 14 des Kupplungsstößels 10 in die Vertiefung 20 gestattet.The return of the distance comb 3 - for example to switch the hair clipper to a shorter cutting length - is carried out in a simple manner by pushing the slide switch 11 back in the direction opposite the arrow direction x. Here, the clutch plunger 10 is moved in the same direction of thrust and, due to the action of the positive guide 27, the clutch wall 16 of the spacer ridge 3, as a result of the abutment of the ram-side beveled edge 38 on the corresponding beveled edge 39 of the clutch wall 16, is taken into the detent position “1” which causes the smallest cutting length , which is characterized by the engagement of the detent 33 in the notch 34.3. When the clutch plunger 10 is pushed back further by means of the slide switch 11 in the opposite direction of the arrow x, the coupling lug 14 of the plunger 10 arrives after passing the locking edge 40 which, according to FIG. 5, extends somewhat below the level of the locking shoulder 24 formed by the coupling wall 16, that is to say in the coupling direction x protrudes by a small amount compared to the latter, in the region of the coupling groove 17, which allows the coupling lug 14 of the coupling tappet 10, which rests on the comb-side locking shoulder 18, to escape into the recess 20.

Beim weiteren Zurückschieben des Kupplungsstößels 10 mittels des Schiebeschalters 11 überwindet deshalb die Kupplungsnase 14 durch Verschwenken des Stößels 10 um das Filmscharnier 15 entgegen dem Uhrzeigersinn die Rastschulter 18 und gibt dadurch den Distanzkamm zum manuellen Abheben frei. Der Schiebeschalter 11 der Haarschneidemaschine gelangt dabei in die durch Eingriff der Rastnase 33 in die Rastkerbe 34.2 gekennzeichnete « Ein »-Stellung, in der die Haarschneidemaschine 1 noch eingeschaltet ist. Das nochmalige Zurückschieben des Schiebeschalters 11 bis zum Einfallen seines Rasthebels 32, 33 in die Rastkerbe 34.1 bewirkt schließlich das Ausschalten des gesamten Antriebs der Haarschneidemaschine 1 mittels des vom Schiebeschalter 11 gesteuerten bzw. betätigten elektrischen Schalters 21.When pushing the clutch plunger 10 further by means of the slide switch 11, the coupling lug 14 therefore overcomes the locking shoulder 18 by pivoting the plunger 10 about the film hinge 15 counterclockwise and thereby releases the distance comb for manual lifting. The slide switch 11 of the The hair clipper comes into the “on” position characterized by the engagement of the catch 33 in the catch notch 34.2, in which the clipper 1 is still switched on. The repeated pushing back of the slide switch 11 until its latching lever 32, 33 engages in the latching notch 34.1 finally causes the entire drive of the hair clipper 1 to be switched off by means of the electrical switch 21 which is controlled or actuated by the slide switch 11.

Die Fig. 7 bis 10 zeigen in schematischer Darstellung die einzelnen Kupplungsphasen zwischen der Haarschneidemaschine 1 und dem auf deren Scherkopf 2 aufgesetzten Distanzkamm 3.7 to 10 show a schematic representation of the individual coupling phases between the hair clipper 1 and the spacing comb 3 placed on the shaving head 2 thereof.

Die Fig. 7 zeigt die hier mit « Aus bezeichnete Ausschaltstellung der Haarschneidemaschine 1. Der Kupplungsstößel 10 befindet sich hier noch unterhalb des auf den Scherkopf 2 locker aufgesetzten Distanzkammes 3. Eine Kupplung mit letzterem ist noch nicht erfolgt.FIG. 7 shows the switch-off position of the hair clipper 1, which is referred to here as "from". The clutch plunger 10 is still below the spacer comb 3 loosely placed on the shaving head 2. A clutch with the latter has not yet taken place.

Gemäß Fig. 8 ist der Kupplungsstößel 10 mittels des Schiebeschalters 11 in die « Ein »-Stellung überführt worden, in der die Haarschneidemaschine 1 ohne Verschiebung des aufgesetzten Distanzkammes in Betrieb genommen wird. Hierbei hat die Kupplungsnase 14 des Stößels 10, der durch das Filmscharnier 15 schwenkbar ist, die Rastschulter 18 des Distanzkammes 3 übergriffen und den Distanzkamm 3 am Scherkopf 2 der Haarschneidemaschine 1 genen Herausfallen gesichert. Der Distanzkamm 3 kann auch in dieser Kupplungsstellung jederzeit vom Scherkopf 2 abgehoben werden, wobei dann die Kupplungsnase 14. des Stößels 10 durch die Rastschulter 18 des Distanzkammes 3 in die Vertiefung 20 der Führung 9 der Haarschneidemaschine 1 zurückgedrängt wird.According to FIG. 8, the clutch plunger 10 has been moved into the “on” position by means of the slide switch 11, in which the hair clipper 1 is put into operation without moving the spacer comb attached. Here, the coupling lug 14 of the plunger 10, which can be pivoted through the film hinge 15, overlaps the locking shoulder 18 of the spacing comb 3 and secured the spacing comb 3 on the shaving head 2 of the hair clipper 1 to prevent it from falling out. The spacer comb 3 can also be lifted off the shaving head 2 at any time in this coupling position, the coupling lug 14 of the plunger 10 then being pushed back into the recess 20 of the guide 9 of the hair clipper 1 by the latching shoulder 18 of the spacing comb 3.

Die Fig. 9 zeigt die erste gesperrte Kupplungsstellung des Distanzkammes 3 am Scherkopf 2 der Haarschneidemaschine 1, in der sich der Distanzkamm 3 in der die kürzeste Schittlänge erzielenden Stellung « 1 befindet. Die Kupplungsnase 14 des Kupplungsstößels 10 befinder sich hierbei - nach dem Passieren der Sperrkante 40 - bereits in einem Bereich, der einerseits von der Gehäusewandung 19 der Haarschneidemaschine 1 und andererseits von der Kupplungswandung 16 des Distanzkammes 3 gebildet wird. Infolge dieser Zwangsführung 27 wird der Kupplungsstößel 10 an einem Ausweichen um seine Scharnierachse 15 gehindert und sonach beim Fortschalten des Schiebeschalters 11 allein in Kupplungsrichtung x, also in oder parallel zur Längsachse der Haarschneidemaschine 1, fortbewegt. Hierdurch kann der Distanzkamm 3 in vorbeschriebener Weise mittels der Stoßkante 23 in weitere Raststellungen bewegt werden.FIG. 9 shows the first locked coupling position of the spacer comb 3 on the shaving head 2 of the hair clipper 1, in which the spacer comb 3 is in the position «1 which achieves the shortest cutting length. After passing the locking edge 40, the coupling lug 14 of the coupling plunger 10 is already in an area which is formed on the one hand by the housing wall 19 of the hair clipper 1 and on the other hand by the coupling wall 16 of the spacer comb 3. As a result of this forced guidance 27, the coupling plunger 10 is prevented from evading around its hinge axis 15 and is therefore moved only in the coupling direction x when the slide switch 11 is advanced, that is to say in or parallel to the longitudinal axis of the hair clipper 1. As a result, the spacer comb 3 can be moved into further latching positions in the manner described above by means of the abutting edge 23.

Die Fig. 10 zeigt schließlich das weitere Emporschieben des Distanzkammes 3 in eine seiner weiteren, die Länge der zu schneidenden Haare jeweils vergrößernden Raststellungen, die auf der Markierungsskala 35 mit « 2 ", « 3 oder « 4 » bezeichnet sind. Hierbei liegt die Vorderwand 23 des Kupplungsstößels 10 an der Sperrschulter 24 der Kupplungswandung 16 an.10 finally shows the further pushing up of the spacer comb 3 into one of its further detent positions, which increase the length of the hair to be cut and which are labeled “2 ” , “3 or“ 4 ”on the marking scale 35. The front wall lies here 23 of the clutch plunger 10 on the locking shoulder 24 of the clutch wall 16.

Das Zurückschieben des Distanzkammes 3 erfolgt gemäß Fig. 10 in umgekehrter Richtung, also durch Zurückbewegung des zwangsgeführten Kupplungsstößels 10 mittels des Schiebeschalters 11 entgegen der Pfeilrichtung x, wobei durch das Anlegen der Schrägkante 38 der Kupplungsnase 14 an die Schrägkante 39 der kammseitigen Kupplungswandung 16 der Distanzkamm 3 in eine seiner unteren Raststellungen zurückgezogen wird. Bei ursprünglicher Raststellung « 4 kann dies beispielsweise die Raststellung « 3 », « 2 » oder « 1 » sein. Erst beim Zurückschalten des Schiebeschalters 11 in die « Ein »- oder in die « Aus »-Stellung kann der Kupplungsstößel 10 in die von der Führung 9 gebildete Vertiefung 20 treten und den auf dem Scherkopf 2 sitzenden Distanzkamm 3 freigeben, so daß dieser von der Haarschneidemaschine 1 abgehoben werden kann.10, in the opposite direction, that is, by moving the positively guided clutch plunger 10 backwards by means of the slide switch 11 against the direction of the arrow x, by applying the inclined edge 38 of the coupling lug 14 to the inclined edge 39 of the comb-side coupling wall 16 of the spacer comb 3 is withdrawn into one of its lower rest positions. With the original locking position “4”, this can be, for example, the locking position “3”, “2” or “1”. Only when the slide switch 11 is switched back into the “on” or “off” position can the clutch plunger 10 enter the recess 20 formed by the guide 9 and release the spacing comb 3 seated on the shaving head 2, so that it is released from the Hair clipper 1 can be lifted off.

In der Fig. 11 ist eine Variante der erfindungsgemäßen Haarschneidemaschine dargestellt, deren Kupplung mit dem aufsetzbaren Distanzkamm durch eine vorteilhafte, sich bedienungserleichtemd auswirkende Konzeption der Kupplung 13 vervollständigt ist.FIG. 11 shows a variant of the hair clipper according to the invention, the coupling of which with the attachable spacer comb is completed by an advantageous design of the coupling 13 which is easy to use.

Ersichtlich läßt die Fig. 11 das vorstehend beschriebene Zusammenwirken der Kupplungsglieder 10, 14 der Haarschneidemaschine 1 mit den Kupplungsmitteln 16, 18 des Distanzkammes 3 erkennen. In der kupplungsseitigen Gehäusewandung 19' der Haarschneidemaschine 1 ist jedoch hier eine Kulisse 41 vorgesehen, die von einer Kurvennut in einer die Führung 9 für den Kupplungsstößel 10 begrenzenden, der Gehäusewandung 19' benachbarten Seitenwandung 42 eingeformt ist. In der Kulisse 41 greift ein dem Kupplungsstößel 10 angeformter Führungszapfen 43 ein, der auch aus einer an einem solchen Zapfen angebrachten Führungsrolle bestehen kann. Der Führungszapfen 43 wirkt nun mit der Kulisse 41 beim Emporschieben des Kupplungsstößels 10 infolge des Umschaltens des Schiebeschalters 11 der Haarschneidemaschine aus deren « Aus »-Stellung in die « Ein »-Stellung im Sinne der Erleichterung des Überführens des Stößels 10 in seine hinter die Rastschulter 18 der kammseitigen Kupplungswandung 16 greifende, das Sichern des Distanzkammes 3 in seiner auf den Scherkopf 2 lediglich aufgesetzten Lage bewirkende Kupplungsstellung.11 clearly shows the interaction of the coupling members 10, 14 of the hair clipper 1 described above with the coupling means 16, 18 of the spacer comb 3. In the clutch-side housing wall 19 'of the hair clipper 1, however, a link 41 is provided here, which is formed by a curved groove in a side wall 42 adjacent to the housing wall 19' and delimiting the guide 9 for the clutch plunger 10. A guide pin 43 integrally formed on the coupling plunger 10 engages in the setting 41 and can also consist of a guide roller attached to such a pin. The guide pin 43 now acts with the link 41 when the clutch plunger 10 is pushed up as a result of the slide switch 11 of the hair clipper being switched from its “off” position to the “on” position in the sense of facilitating the transfer of the plunger 10 into its behind the latching shoulder 18 of the comb-side coupling wall 16 engaging, securing the spacing comb 3 in its only on the shaving head 2 position effecting coupling position.

Wie ersichtlich wird also hierbei der Kupplungsstößel 10 mit der angeformten Kupplungsnase 14 von der Kulisse 41 über die Rastschulter 18 der kammseitigen Kupplungswandung 16 gehoben (erste gestrichelte Position) und sodann hinter der Rastschulter 18 in seine « Ein »-Stellung überführt (zweite gestrichelte Position), wonach der Stößel 10 in den Bereich der Zwangsführung 27' gelangt, in dem der Kupplungsstößel 10 - mit seiner Stoßkante 23 gegen die Sperrschulter 24 der kammseitigen Kupplungswandung 16 prallend - den Distanzkamm 3 in seine jeweils größere Schnittlängen bewirkende Raststellungen bewegt.As can be seen, the clutch plunger 10 with the molded coupling lug 14 is lifted from the link 41 over the locking shoulder 18 of the coupling wall 16 on the ridge side (first dashed position) and then moved into its “on” position behind the locking shoulder 18 (second dashed position) , After which the plunger 10 arrives in the region of the positive guide 27 ', in which the coupling plunger 10 - with its abutting edge 23 crashing against the locking shoulder 24 of the comb-side coupling wall 16 - moves the spacing comb 3 into its detent positions, each of which has greater cutting lengths.

Die Ausstattung des Kupplungsstößels 10 mit den in die Kulisse 41 eingreifenden Führungszapfen 43 erlaubt es, auch die Zwangsführung 27 als Fortsetzung der Kulisse 41 zu konzipieren, also diese Zwangsführung abweichend von den Ausführungen nach den Fig. 5 bis 10 aus der Gehäusewandung 19 der Haarschneidemaschine 1 und der Kupplungswandung 16 des Distanzkammes 3 zu bilden. Die so noch die Zwangsführung 27' einschließende Kulisse 41 gewährleistet eine besonders sichere verkantungsfreie und verschleißarme Führung des ledigleich von ihr um das Filmscharnier 15 verschwenkten und gerardlinig geführten Kupplungsstößels 10 des Schiebeschalters 11 der Haarschneidemaschine 1.Equipping the clutch plunger 10 with the guide pins 43 engaging in the link 41 also allows the positive guide 27 to be designed as a continuation of the link 41, that is to say this positive guide differs from the embodiments according to FIGS. 5 to 10 from the housing wall 19 of the hair clipper 1 and to form the coupling wall 16 of the spacer comb 3. The gate 41 'thus including the positive guide 27' ensures a particularly secure canting-free and low-wear guidance of the coupling plunger 10 of the slide switch 11 of the hair clipper 1, which is pivoted by it about the film hinge 15 and is guided in a straight line.

Zum Vorzentrieren des auf den Scherkopf 2 der Haarschneidemaschine 1 aufgesteckten Distanzkammes 3 können den Innenseiten der beiden parallelen Seitenwandungen des Distanzkammes Rastnocken 44 zugeordnet sein, die in entsprechende Rastmulden 45 in den Außenseiten der korrespondierenden Außenwandungen des Scherkopfes des Körpers 7 der Haarschneidemaschine 1 zusammenwirken.To pre-center the spacer comb 3 plugged onto the shaving head 2 of the hair clipper 1, latching cams 44 can be assigned to the inner sides of the two parallel side walls of the spacer comb, which engage in corresponding recesses 45 in the outer sides of the corresponding outer walls of the shaving head of the body 7 of the hair clipper 1.

Fig. 12 bis Fig. 14 zeigt eine weitere Ausführungsform der Haarschneidemaschine und des Distanzkammes. Hierbei zeigt Fig. 12 einen Ausschnitt der Frontansicht der Haarschneidemaschine ohne Distanzkamm, Fig. 13 die Darstellung der Kupplung zwischen der Haarschneidemaschine und dem aufgesetzten Distanzkamm im Schnitt von der Seite (entsprechend Fig. 5) und Fig. 14 einen Ausschnitt der Kupplungswandung des Distanzkammes von innen gesehen. Wie hieraus ersichtlich ist, wird bei dieser Ausführungsform der Distanzkamm 3 von der Kupplungsnase 14 des Kupplungsstößels 10 bereits in der Ausschaltstellung « Aus » festgehalten und somit gegen Herausfallen gesichert. Bei den bisher beschriebenen Ausführungsformen erfolgt dies erst in der Einschaltstellung « Ein ».FIGS. 12 to 14 show a further embodiment of the hair clipper and the distance comb. 12 shows a section of the front view of the hair clipper without a distance comb, FIG. 13 shows the representation of the coupling between the hair clipper and the attached distance comb in section from the side (corresponding to FIG. 5) and FIG. 14 shows a section of the coupling wall of the distance comb from seen inside. As can be seen from this, in this embodiment the spacer comb 3 is already held by the coupling lug 14 of the coupling tappet 10 in the off position “off” and is thus secured against falling out. In the embodiments described so far, this only takes place in the “on” position.

Beim Aufsetzen des Distanzkammes 3 auf den Scherkopf der Haarschneidemaschine gleitet die Kupplungsnase 14 des Kupplungsstößels 10 in der Aufstecknut 47 der Kupplungswandung 16 des Distanzkammes. An der Schrägkante 29' der Rastschulter 18' des Distanzkammes wird der Kupplungsstößel 10 durch Verschenken um das Filmschamier 15 in die Vertiefung 20 der Gehäusewandung 19 gedrückt. Hinter der Rastschulter 18' schwenkt der Kupplungsstößel 10 wieder zurück in die in Fig. 13 dargestellte Lage. Diese Lage entspricht der in Fig. 5 gezeigten, allerdings befindet sich hier in Fig. 13 der Schiebeschalter 11 noch in der «Aus »-Stellung, während er in Fig. 5 bereits in der « Ein »-Stellung ist, so daß in Fig. 13 der Distanzkamm bereits in der « Aus »-Stellung federnd festgehalten wird. Das Abziehen des Kammes vom Scherkopf in dieser Lage wird auch hier durch das Zusammenwirken der Schrägkante 38 an der Kupplungsnase 14 des Kupplungsstößels 10 und der Schrägkante 39 an der Rastschulter 18' des Distanzkammes bewirkt.When the spacer comb 3 is placed on the shaving head of the hair clipper, the coupling lug 14 of the coupling plunger 10 slides in the push-on groove 47 of the coupling wall 16 of the spacing comb. On the inclined edge 29 'of the locking shoulder 18' of the spacer comb, the coupling plunger 10 is pressed into the recess 20 of the housing wall 19 by giving it away around the film hinge 15. Behind the locking shoulder 18 ', the coupling plunger 10 pivots back into the position shown in FIG. 13. This position corresponds to that shown in FIG. 5, but here in FIG. 13 the slide switch 11 is still in the “off” position, while in FIG. 5 it is already in the “on” position, so that in FIG 13 the distance comb is already held in the "off" position. The removal of the comb from the shaving head in this position is also effected here by the interaction of the inclined edge 38 on the coupling lug 14 of the coupling tappet 10 and the inclined edge 39 on the locking shoulder 18 'of the spacing comb.

Wird die Haarschneidemaschine mit aufgesetztem Distanzkamm mittels des Schiebeschalters 11 nun eingeschaltet, wird die Kupplungsnase 14 des Kupplungsstößels 10 nicht nur nach oben, sondern auch seitwärts versetzt geführt (vgl. Fig. 12). Diese schräg nach oben links gerichtete Führung der Kupplungsnase 14 erfolgt in einer Kulisse 51 in der Frontwandung 12 der Haarschneidemaschine. Diese Kulisse 51 in der Frontwandung 12 ist deckungsgleich mit der Kupplungskulisse 46 in der Kupplungswandung 16 des Distanzkammes (Fig. 14), so daß der Distanzkamm bei Führung des Kupplungsstößels 10 von der « Aus in die « Ein »-Stellung (und umgekehrt) mit der Kupplungsnase 14 nicht in Eingriff kommt.If the hair clipper with the spacer comb attached is now switched on by means of the slide switch 11, the coupling lug 14 of the coupling tappet 10 is not only guided upwards but also offset sideways (cf. FIG. 12). This obliquely upward left guidance of the coupling nose 14 takes place in a backdrop 51 in the front wall 12 of the hair clipper. This link 51 in the front wall 12 is congruent with the clutch link 46 in the clutch wall 16 of the spacer comb (Fig. 14), so that the spacer comb when the clutch plunger 10 is guided from the "off to the" on "position (and vice versa) the coupling lug 14 does not come into engagement.

In dieser « Ein »-Stellung ist die Maschine eingeschaltet und der Distanzkamm kann nicht mehr abgezogen werden, da sich der Kupplungsstößel 10 nun bereits in der Zwangsführung 27, die ein Ausweichen des Kupplungsstößel 10 nach hinten, entsprechend den anderen beschriebenen Ausführungsformen, verhindert. Ein seitliches Ausweichen des Kupplungsstößels 10 in dieser Lage beim versuchten Abziehen des Distanzkammes ist auch nicht möglich, da er mittels seiner Kupplungsnase 14 in der Kulisse 51 der Frontwandung gehalten ist und an der Sperrkante 50 der Kupplungskulisse 46 in der Kupplungswandung 16 des Distanzkammes anliegt.In this “on” position, the machine is switched on and the distance comb can no longer be removed, since the clutch plunger 10 is already prevented in the forced guide 27, which prevents the clutch plunger 10 from escaping to the rear, in accordance with the other described embodiments. A lateral deflection of the clutch plunger 10 in this position when attempting to pull off the spacer comb is also not possible, since it is held in the link 51 of the front wall by means of its coupling nose 14 and bears against the locking edge 50 of the clutch link 46 in the clutch wall 16 of the spacer comb.

Wird nun der Schiebeschalter 11 in die weiteren Rastpositionen zur Vergrößerung der Schnittlänge nach oben geschoben, erfolgt die seitliche Führung der Kupplungsnase 14 in einer Zwangsführung 48, die gegenüber der Längsachse x der Haarschneidemaschine parallel versetzt angeordnet ist. Die Vorderwand 23 des Kupplungsstößels 10 liegt nun an der Sperrschulter 24' der Kupplungskulisse 46 des Distanzkammes und schiebt diesen, wie vorne beschrieben, nach oben.If the slide switch 11 is now pushed into the further latching positions to increase the cutting length, the lateral guide of the coupling lug 14 takes place in a positive guide 48 which is offset parallel to the longitudinal axis x of the hair clipper. The front wall 23 of the coupling plunger 10 now lies on the locking shoulder 24 'of the coupling link 46 of the spacing comb and pushes it upwards, as described above.

Beim Zurückschieben erfolgt die Bewedung in umgekehrter Reihenfolge. Bis zur « Ein »-Stellung nimmt der Kupplungsstößel 10 den Distanzkamm mit, da die Kupplungsnase 14 an der Sperrkante 50 der Kupplungskulisse 46 des Distanzkammes anliegt und der Kupplungsstößel weder seitlich infolge der Zwangsführung 48 noch nach hinten infolge der Zwangsführung 27 ausweichen kann. Erst in der « Aus »-Stellung kann der Kupplungsstößel 10 wieder nach hinten ausweichen und so der Distanzkamm abgezogen werden.When pushing back, the application takes place in reverse order. Up to the "on" position, the clutch plunger 10 takes the distance comb with it, since the coupling lug 14 rests on the locking edge 50 of the coupling link 46 of the distance comb and the clutch plunger cannot deflect laterally as a result of the positive guide 48 or to the rear as a result of the positive guide 27. Only in the "off" position can the clutch plunger 10 move backwards and the distance comb be pulled off.

Eine weitere vorteilhafte Ausgestaltung der Kupplungsmittel zeigen die Fig. 15 bis 17. Die Ansichten der Fig. 15, 16 bzw. 17 entsprechen denen der Fig. 12, 13 bzw. 14. Auch hier wird der Distanzkamm bereits in der « Aus »-Stellung festgehalten. Das Zusammenwirken der Kupplungsmittel beim Aufsetzen des Distanzkammes auf den Scherkopf erfolgt analog der Beschreibung zu den Fig. 12 bis 14. Unterschiedlich sind hier die Kulisse 51' in der Frontwandung 12 (Fig. 15) und die hierzu deckungsgleiche Kupplungskulisse 46' der Kupplungswandung 16 (Fig. 17) ausgeführt. Sie sind beide Kreisausschnittsförmig ausgeführt.A further advantageous embodiment of the coupling means is shown in FIGS. 15 to 17. The views in FIGS. 15, 16 and 17 correspond to those in FIGS. 12, 13 and 14. Here too, the distance comb is already in the “off” position captured. The interaction of the coupling means when the spacer comb is placed on the shaving head takes place analogously to the description of FIGS. 12 to 14. Different here are the link 51 'in the front wall 12 (FIG. 15) and the congruent coupling link 46' of the coupling wall 16 ( Fig. 17) executed. They are both circular sections.

Von der « Aus »-Stellung in die « Ein »-Stellung wird die Kupplungsnase 14 des Kupplungsstößels 10 seitlich in der Kulisse 51' (Fig. 15) bogenförmig um die Nocke 53 herumgefürht, so daß in der « Ein »-Stellung der Kupplungsstößel wieder in der Längsachse x der Haarschneidemaschine liegt.From the "off" position to the "on" position the coupling lug 14 of the coupling tappet 10 is guided laterally in the link 51 '(FIG. 15) in an arc around the cam 53, so that in the “on” position the coupling tappet is again in the longitudinal axis x of the hair clipper.

Beim Weiterschieben in die nächsten Rastpositionen wird nun die Kupplungsnase 14 seitlich in einer Zwangsführung 52 geleitet, deren Längsachse mit der Längsachse x des Gerätes bzw. mit der Längachse des Kupplungsstößels 10 identisch ist. Hierdurch steht der Kupplungsstößel 10 durch das Filmschamier 49, im Gegensatz zu der Ausführungsform nach Fig. 12-14, in allen Rastpositionen bzw. Raststellungen nicht unter Spannung. Beim Zurückschieben von höheren in niedrigere Rastpositionen (bis zur « Ein »-Stellung) liegt die Unterkante der Kupplungsnase 14 an der Sperrkante 50' der Kupplungskulisse 46' bzw. der Rastnase 54 des Distanzkammes. Ansonsten ist die Wirkungsweise dieser Ausführungsform dieselbe wie die der Fig. 12-14.When pushing further into the next locking positions, the coupling lug 14 is now guided laterally in a positive guide 52, the longitudinal axis of which is identical to the longitudinal axis x of the device or to the longitudinal axis of the coupling plunger 10. As a result, the clutch plunger 10 is not under tension in all locking positions or locking positions due to the film hinge 49, in contrast to the embodiment according to FIGS. 12-14. When pushing back from higher to lower locking positions (up to the "on" position), the lower edge of the coupling lug 14 lies on the locking edge 50 'of the coupling link 46' or the locking lug 54 of the distance comb. Otherwise, the operation of this embodiment is the same as that of FIGS. 12-14.
