Description

Elektrische Haarschneidemaschine Electric hair clipper
Die Erfindung betrifft eine elektrische Haarschneidemaschine mit einem Scherkcpf sowie mit einem auf den Scherkopf aufsetzbaren Distanzkamm zur gleitenden Auflage auf der zu behandelnden Haut- oberfläche, der in verschiedenen Raststellungen bezüglich der Vorderkante des Scherkopfes einstellbar ist, sowie mit einem Schiebeschalter zum Ein- und Ausschalten des Antriebes der Haar¬ schneidemaschine, wobei der Distanzkamm und der Schiebeschalter mit in Eingriff bringbaren Kupplungsmitteln versehen sind und zu der "Ein"- und "Aus"-Stellung des Schiebeschalters weitere Rast¬ stellungen vorgesehen sind.The invention relates to an electric hair clipper with a shaving head and with a spacer comb that can be placed on the shaving head for sliding contact on the surface of the skin to be treated, which can be adjusted in different latching positions with respect to the front edge of the shaving head, and with a slide switch for switching the on and off Drive of the hair-cutting machine, the spacing comb and the slide switch being provided with coupling means which can be brought into engagement and further latching positions are provided for the "on" and "off" position of the slide switch.
Eine solche Haarschneidemaschine ist aus der DE-PS 3529516 be¬ kannt. Zum Abschalten des Antriebs muß hier der Benutzer - unab¬ hängig davon, mit welcher Schnittlänge er sich die Haare ge¬ schnitten hat - den Schiebeschalter in die "Aus"-Position "0" zurückstellen. Hierdurch wird automatisch auch der Distanzkamm in die Position mit der kleinsten Schnittlänge zurückgestellt, so daß der Benutzer bei der nächsten Anwendung nicht mehr feststel¬ len kann, mit welcher Schnittlänge er sich beim letzten Mal die Haare geschnitten hat.Such a hair clipper is known from DE-PS 3529516. To switch off the drive, the user has to reset the slide switch to the "off" position "0" regardless of the cutting length with which he has cut his hair. As a result, the spacing comb is automatically returned to the position with the smallest cutting length, so that the next time the user is used, it is no longer possible to determine the cutting length with which the hair was cut the last time.
Aufgabe der Erfindung ist es deshalb, eine Haarschneidemaschine der eingangs genannten Art so auszugestalten, daß der Benutzer eine als günstig gewählte Schnittlänge bei einer erneuten Inbe- nutzungsnahme wiedererkennen kann. Diese Aufgabe wird dadurch gelöst, daß ein VorwahlSchieber vorge¬ sehen ist, der so eingestellt werden kann, daß der Antrieb der Haarschneidemaschine erst bei einer vorbestimmten Raststellung einschaltet.The object of the invention is therefore to design a hair clipper of the type mentioned at the outset in such a way that the user can recognize a cut length that has been selected as favorable when it is used again. This object is achieved in that a preselection slide is provided which can be set such that the drive of the hair clipper only switches on at a predetermined latching position.

Die Funktionsweise der Haarschneidemaschine soll nun zunächst ohne den vorgesehenen VorwahlSchieber erläutert werden.The mode of operation of the hair clipper will now be explained without the intended slide switch.
Wie die Fig. 1 bis 4 erkennen lassen, besteht die Haarschnei¬ demaschine 1 im wesentlichen aus einem schmalen, haptisch gestal¬ teten 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 Schermesser 6 gebildeten Scherkopfes 2 in vorbestimmtem Abstand zur jeweils zu behandelnden Hautoberfläche, beispielsweise der Kopfhaut einer zu frisierenden Person, zu hal¬ ten, wobei der Distanzkamm 3 - wie noch später erläutert - in un¬ terschiedlichen Hubstellungen gegenüber dem Körper 7 der Haar¬ schneidemaschine 1 an deren Scherkopf 2 positionierbar ist.As can be seen in FIGS. 1 to 4, the hair clipper 1 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 placed on the shaving head 2 3 is covered. The purpose of the spacer comb 3 is to keep the front edge 4 of the shaving head 2 formed from a fixed shaving comb plate 5 and a shaving blade 6 which slides back and forth on it at a predetermined distance from the skin surface to be treated, for example the scalp of a person to be styled , wherein the spacing comb 3 - as explained later - can be positioned in different stroke positions relative to the body 7 of the hair-cutting machine 1 on its shaving head 2.
Der Distanzkamm 3 umfaßt als Hohlkörper den Körper 7 der Haar¬ schneidemaschine 1 im Bereich seines Scherkopfes 1 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 abge¬ schnitten werden. Die hierbei verbleibende Länge der abgeschnit¬ tenen Haare entspricht - bei auf die Hautoberfläche aufgesetzten Stützen 8 - dem Abstand der Vorderkante der zahnförmigen Stützen 8 von der Vorder- oder Schneidkante des Scherkopfes 2 bzw. des ihm zugehörigen Schermessers 6, wobei dieser Abstand - wie be¬ reits erwähnt - bei der Haarschneidemaschine 1 veränderbar ist.The spacer comb 3 comprises, as a hollow body, the body 7 of the hair-cutting machine 1 in the area of its shaving head 1 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 the shaving knife 6 thereof they are then cut off. The remaining length of the cut hair corresponds - in the case of supports 8 placed on the skin surface - to the distance from the front edge of the tooth-shaped supports 8 from the front or cutting edge of the shaving head 2 or the shaving knife 6 associated with it, this distance - as already mentioned - can be changed in the hair clipper 1.
Zum funktionsgerechten Gebrauch der Haarschneidemaschine 1 unter Verwendung des die zu schneidende Haarlänge bestimmenden Distanz¬ kammes 3 sind letzterem Kupplungsmittel zugeordnet, die mit ge¬ eigneten Kupplungsgliedern des Körpers 7 der Haarschneidemaschine 1 zusammenwirken.For functional use of the hair clipper 1 using the distance comb 3 which determines 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 1.
Wie insbesondere die Fig. 4 und 5 zeigen, ist hierzu der Haar¬ schneidemaschine 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 zu¬ geordnet, der sich über die gesamte Breite der Haarschneidema¬ schine 1 erstreckt 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 1 ein- oder auszuschalten, sodann die weitere Funktion, den Distanzkamm 3 mit der Haarschneidemaschine 1 funktionsgerecht zu kuppeln bzw. zu entkuppeln, und schließlich die Funktion, den angekuppelten Distanzkamm 3 in jeweils andere Distanzen bewirkende Gebrauchs- stellungen zu überführen.As shown in FIGS. 4 and 5 in particular, 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 tappet 10 is assigned a slide switch 11 which extends over the entire width of the hair clipping machine 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 firstly that of switching the electrical or mechanical drive of the hair clipper 1 on or off, then the further function of coupling or uncoupling the distance comb 3 with the hair clipper 1 in a functional manner, and finally the function that Coupled coupled distance comb 3 in different positions causing different distances.
Die Funktion des mittels des 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 Kupp¬ lungsphasen - die Fig. 5 bis 10.The function of the lengthwise by means of the slide switch 11 inside and below the front wall 12 of the hair clipper 1 displaceable coupling plunger 10 in cooperation with the coupling means of the spacer comb 3 show - in several coupling phases - 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 1 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 spacer comb 3 which can be placed on the shaving head 2 of the body 7 of the hair clipper 1.
Wie ersichtlich, ist dem mit dem Schiebeschalter 11 verbundenen Kupplungsstößel 10 eine Kupplungsnase 14 angeformt, die um die Achse eines dem Kupplungsstößels 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 formed on the coupling 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, aufge¬ setzte Distanzkamm 3 ist im Bereich seiner als Kupplungsmittel dienende Wandung 16 eine den Kupplungsstößel 10 einschließlich seiner Kupplungsnase 14 aufnehmende Kupplungsnut 17 zugeordnet. Diese Kupplungsnut 17 umfaßt eine der Kupplungswandung 16 des Distanzkammes 3 angeformte Rastschulter 18, die von der Kupp¬ lungsnase 14 des Kupplungsstößels 10 durch Ausweichen in die von einer Gehäusewand 19 der Haarschneidemaschine 1 gebildeten Ver¬ tiefung 20 im Bereich der Kupplungsnut 17 während des Aufsetzens des Distanzkammes 3 überwunden wird. Der aufgesetzte Distanzkamm 3 wird sonach von der seine Rast¬ schulter 18 hintergreifenden Kupplungsnase 14 des Kupplungs¬ stößels 10 gehalten und damit gegen ungewolltes Lösen von der Haarschneidemaschine 1 gesichert. In dieser Aufsetzstellung der so miteinander in Verbindung gebrachten Kupplungsglieder 10, 14 der Haarschneidemaschine 1 und den Kupplungsgliedern 17, 18 des Distanzkammes 3 befindet sich der auch auf elektrische Schalter 21 für den Antrieb einwirkende Schiebeschalter 11 noch in der "Aus"-Stel1ung, in der der Speisestromkreis der Haarschneidema¬ schine 1 geöffnet ist. Durch anschließendes Verschieben des Schiebeschalters 11 und damit auch des Kupplungsstößels 10 in Richtung der Achse x der Haarschneidemaschine 1 - gleich Hubrich¬ tung x des Distanzkammes 3 - von der in Fig. 5 dargestellten Position "Aus" in die darin gestrichelt dargestellte Position "Ein" betätigt der Schiebeschalter 11 den Schalter, wodurch der Speisestromkreis der Haarschneidemaschine 1 geschlossenen und damit deren nicht dargestellter Antrieb eingeschaltet ist.The spacer comb 3 surrounding the shaving head 2 of the hair clipper 1 is assigned in the region of its wall 16 serving as coupling means a coupling groove 17 receiving the coupling tappet 10 including its coupling lug 14. This coupling groove 17 comprises a locking shoulder 18 formed on the coupling wall 16 of the spacer comb 3, which shoulders from the coupling nose 14 of the coupling tappet 10 by deflecting into the recess 20 formed by a housing wall 19 of the hair clipper 1 in the region of the coupling groove 17 during the mounting of the Distance comb 3 is overcome. The attached spacing comb 3 is thus held by the coupling nose 14 of the coupling plunger 10 engaging behind its locking shoulder 18 and thus secured against unintentional detachment from the hair clipper 1. In this mounting position of the coupling members 10, 14 of the hair clipper 1 and the coupling members 17, 18 of the spacing comb 3 which are brought into connection with one another, the slide switch 11 which also acts on electrical switches 21 for the drive is still in the "off" position, in which the feed circuit of the hair clipping machine 1 is open. By subsequently shifting 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 lifting direction x of the distance comb 3 - from the position "Off" shown in FIG. 5 to the position "On" shown in dashed lines. the slide switch 11 actuates the switch, as a result of which the feed circuit of the hair clipper 1 is closed and thus its drive, not shown, is switched on.
In dieser "Ein"-Stellung gelangt die Vorderwand 23 des Kupplungs¬ stößels 10 an eine der Kupplungswandung 16 des Distanzkammes 3 angeformte Sperrschulter 24, während die der Kupplungsnase 14 (gemäß Fig. 5) abgewandte Seitenwand 25 an der Außenwandung 26 einer durch die Gehäusewand 19 der Haarschneidemaschine 1 und durch die Kupplungswandung 16 des Distanzkammes 3 gebildeten Zwangsführung 27 gleitend zur Anlage kommt. Damit ist in der "Ein"-Stel1ung des Schiebeschalters 11 der Kupplungsstδßel 10 durch die Zwangsführung 27 an einem elastischen Ausweichen von der Sperrschulter 24 gehindert. Die das Ausweichen erleichternde Schrägkante 28 des Kupplungsstoßels 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 locking shoulder 24 formed on the coupling wall 16 of the spacer comb 3, while the side wall 25 facing away from the coupling lug 14 (according to FIG. 5) on the outer wall 26 one through the housing wall 19 of the hair clipper 1 and the positive guide 27 formed by the coupling wall 16 of the distance comb 3 slidably comes to rest. Thus, in the "on" position of the slide switch 11, the clutch plunger 10 is prevented from elastically evading by the locking shoulder 24 by the positive guide 27. The easing the sloping edge 28 of the clutch plunger 10, which when the Distance comb 3 cooperates with the inclined edge 29 of the locking shoulder 18 of the comb-side coupling wall 16, does not come into effect here.
Die Fig. 6 zeigt in einer schematischen Frontansicht ein sowohl den Kupplungsstößel 10 als auch den Schiebeschalter 11 umfassen¬ den, vertikal verschiebliches Griffstück 30, das der Haarschnei¬ demaschine 1 als ZentralSchalter dient. Dem Griffstück 30 ist hier um ein eingeformtes Filmscharnier 31 schwenkender Rasthebel 32 angeformt, dessen Ratsnase 33 unter Eigenfederung in Rastker¬ ben einer gerätefest angeordneten Rastenleiste 34 der Haarschnei¬ demaschine 1 eingreift und mit diesen je ein Rastgesperre bildet. Der Eingriff der Rastnase 33 in die (gemäß Fig. 6) unterste Rast¬ kerbe 34.1 bestimmt die "Aus"-Stellung des Schiebeschalters 11. Wird der Schiebeschalter 11 um eine Rastteilung nach oben gescho¬ ben, so gelangt die Rastnase 33 in die Rastkerbe 34.2, welche "Ein"-Stellung des Schiebeschalters 11 bestimmt. Der Kupplungs¬ stößel 10 gelangt hierbei aus seiner nach Überwindung der Rast¬ schulter 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 as a central switch for the hair clipper 1. The handle 30 is formed here about a molded-in film hinge 31 pivoting locking lever 32, the council nose 33 engages under self-resilience in locking notches in a device-fixed locking bar 34 of the hair clipper 1 and forms a locking mechanism with each. The engagement of the detent 33 in the lowest detent notch 34.1 (according to FIG. 6) determines the “off” position of the slide switch 11. If the slide switch 11 is pushed up by one detent, the detent 33 arrives in the detent notch 34.2, which determines "on" position of the slide switch 11. The coupling tappet 10 comes from its "off" position assumed after overcoming the locking shoulder 18 into the "on" position in which its coupling nose 14 comes to rest on the locking shoulder 24 and the inner wall 26 of the positive guide 27 and so that the coupling of the hair clipper 1 with the spacer comb 3 is completed for the purpose of positioning the spacer comb.
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 mitbe¬ wegten Kupplungsstößel 10 der Distanzkamm 3 infolge der Anlage der Stößelseitigen Vorderwand 23 an der Sperrschulter 24 der Kupplungswandung 16 in eine erste Raststelung gehoben. Diese erste Raststellung bewirkt das Schneiden der vom Distanzkamm 3 erfaßten Haare mit relativ geringer Schnittlänge. Die Raststel¬ lung wird hier von einer dem Scherkopf 2 der HaarschneidemaschineBy 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 moved by the coupling tappet 10 moved in the direction x as a result of the front wall 23 on the tappet resting against the locking shoulder 24 Clutch wall 16 raised to a first latching position. This first detent position causes the hair captured by the spacer comb 3 to be cut with a relatively short cutting length. The locking position is here from a shaving head 2 of the hair clipper
I zugehörigen Markierungsskala 35, deren Ziffer "1" bis "4" in einem Ausschnitt 36 zwischen und unterhalb zweier benachbarten zahnförmigen Stützen 8 des Distanzkammes 3 sichtbar werden, an¬ gezeigt. Eine der Frontseite des Distanzkammes 3 zugeordnete Marke 37 zeigt dabei die jeweilige Raststellung - hier die ge¬ ringstmögliche Raststellung "1" - des Distanzkammes 3 an.I associated marking scale 35, the numbers "1" to "4" are visible in a cutout 36 between and below two adjacent tooth-shaped supports 8 of the spacer comb 3. A mark 37 assigned to the front of the spacing comb 3 indicates the respective latching position - here the lowest possible latching position "1" - of the spacing comb 3.
In gleicher Weise gelangt durch weiteres Nach-Oben-Schieben des Kupplungsstößels 10 mittels des ihm zugeordneten SchiebeschaltersIn the same way, by pushing the clutch plunger 10 further upwards by means of the slide switch assigned to it
II der Distanzkamm 3 in weitere, den Abstand zwischen Scherkopf 2 und Distanzkamm 3 vergrößernde Raststellungen, die durch Ein¬ fallen der Rastnase 33 in die Rastkerben 34.4, 34.5 und 34.6 gekennzeichneten und anhand der Markierungsskala 35 durch die mittels Skalaziffern "1", "2", "3", "4" korrespondierende Marke 37 bzw. durch Ablesen der in Schieberichtung liegende unterste, vom Distanzkamm 3 nicht abgedeckten Skalenziffern angezeigt sind.II of the spacer comb 3 into further detent positions which increase the distance between the shaving head 2 and the spacer comb 3, which are identified by the engagement of the detent 33 in the detent notches 34.4, 34.5 and 34.6 and on the basis of the marking scale 35 by means of scale numbers "1", "2 "," 3 "," 4 "corresponding mark 37 or by reading the lowest scale numbers lying in the sliding direction and not covered by the distance comb 3 are indicated.
Das Zurückfahren des Distanzkammes 3 - beispielsweise zum Um¬ schalten der Haarschneidemaschine 1 auf eine kürzere Schnitt¬ länge - erfolgt in einfacher Weise durch Zurückschieben des Schiebeschalters 11 in der der Pfeilrichtung x entgegengesetzten Richtung. Hierbei wird der Kupplungsstδßel 10 in gleicher Schub¬ richtung bewegt und durch Einwirkung der Zwangsführung 27 die Kupplungswandung 16 des Distanzkammes 3 infolge der Anlage der Stößelseitigen Schrägkante 38 an der mit dieser korrespondieren- den Schrägkante 39 der Kupplungswandung 16 bis in die die gering¬ ste Schnittlänge bewirkende Raststellung "1" mitgenommen, die durch Einfallen der Rastnase 33 in die Rastkerbe 34.3 gekenn¬ zeichnet ist. Beim weiteren Zurückschieben des Kupplungsstößels 10 mittels des Schiebeschalters 11 entgegen der Pfeilrichtung x gelangt die Kupplungsnase 14 des Kupplungsstößels 10 nach Passie¬ ren 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 anliegen¬ den Kupplungsnase 14 des Kupplungsstößels 10 in die Vertiefung 20 gestattet.The return of the distance comb 3 - for example to switch the hair clipper 1 to a shorter cutting length - is carried out in a simple manner by pushing back the slide switch 11 in the direction opposite the arrow direction x. Here, the clutch plunger 10 is moved in the same direction of thrust and, by the action of the positive guide 27, the clutch wall 16 of the spacer comb 3 as a result of the abutment of the tappet-side bevel edge 38 on the side corresponding to the latter. the inclined edge 39 of the coupling wall 16 is taken into the detent position "1" which causes the smallest cutting length and which is characterized by the engagement of the detent 33 in the notch 34.3. When the coupling 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 coupling 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 protrudes by a small amount in the coupling direction x 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 Kupplungsstößels 10 um das Filmscharnier 15 ent¬ gegen dem Uhrzeigersinn die Rastschulter 18 und gibt dadurch den Distanzkamm 3 zum manuellen Abheben frei. Der Schiebeschalter 11 der Haarschneidemaschine 1 gelangt dabei in die durch Eingriff der Rastnase 33 in die Rastkerbe 34.2 gekennzeichnete "Ein"-Stel- lung, in der die Haarschneidemaschine 1 noch eingeschaltet ist. Das nochmalige Zurückschieben des Schiebeschalters 11 bis zum Einfallen seines Rasthebels 32 in die Rastkerbe 34.1 bewirkt schließlich das Ausschalten des gesamten Antriebs der Haarschnei¬ demaschine 1 mittels des vom Schiebeschalter 11 gesteuerten bzw. betätigten elektrischen Schalters 21. Die in Fig. 7 dargestellte Prinzipdarstellung zeigt einen in Längsrichtung beweglichen VorwahlSchieber 60, bestehend aus einer Leiterplatte 66, einem Rasthebel 62 und einer Handhabe 61. Mit¬ tels der Handhabe 61 ist der VorwahlSchieber 60 in verschiedenen Rastpositionen 1, 2, 3 und 4 bewegbar. Diese Rastpositionen wer¬ den durch eine im Gehäuse festgelegte Rastenleiste 64 bestimmt, in deren Rastkerben die am Ende des Rasthebels 62 befindliche Rastnase 63 einrastet.When the coupling plunger 10 is pushed back further by means of the slide switch 11, the coupling lug 14 overcomes the locking shoulder 18 by pivoting the coupling plunger 10 counter-clockwise in the film hinge 15 and thereby releases the distance comb 3 for manual lifting. The slide switch 11 of the hair clipper 1 arrives in the “on” position characterized by the engagement of the catch 33 in the catch notch 34.2, in which the hair clipper 1 is still switched on. The repeated pushing back of the slide switch 11 until its latching lever 32 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 controlled or actuated by the slide switch 11. The basic illustration shown in FIG. 7 shows a preselection slide 60 which is movable in the longitudinal direction and consists of a printed circuit board 66, a locking lever 62 and a handle 61. The handle 61 enables the preselection slide 60 to be moved in different detent positions 1, 2, 3 and 4 . These locking positions are determined by a locking bar 64 fixed in the housing, in whose locking notches the locking lug 63 located at the end of the locking lever 62 snaps into place.
Die Abstände der Rastpositionen des VorwahlSchiebers 60 entspre¬ chen den Abständen der Rastpositionen 1, 2, 3 und 4 des Schiebe¬ schalters 11. Die Rastposition des Schiebeschalters 11 werden durch daran befestigte Rasthebel 32 festgelegt, deren Enden in Rastkerben von ebenfalls im Gehäuse festgelegten Rastenleisten 34 einrasten.The distances between the latching positions of the preselection slide 60 correspond to the distances between the latching positions 1, 2, 3 and 4 of the slide switch 11. The latching position of the slide switch 11 is determined by latching levers 32 fastened to it, the ends of which in latching notches from latching bars likewise fixed in the housing 34 click into place.
Der Schiebeschalter 11 ist mit zwei Schleifkontakten 68 und 78 versehen, wobei der eine Schleifkontakt 78 über die Leiterbahn 77 einer im Gehäuse festgelegten Leiterplatte 76 und der andere Schleifkontakt 68 über die Leiterbahn 67 der Leiterplatte 66 des VorwahlSchiebers 60 gleitet. Die beiden Schleifkontakte 68 und 78 stehen im Schiebeschalter 11 miteinander in Verbindung. Das obere Ende der Leiterbahn 77 ist mit dem Motor M fest und das obere Ende der Leiterbahn 67 über einen Schleifkontakt 69 verbunden. Da die Leiterbahn 77 der feststehenden Leiterplatte 76 mit einem Pol der Spannungsquelle verbunden ist, wird der Motor M eingeschal¬ tet, wenn der Schiebeschalter 11 die beiden Leiterbahnen 77 und 67 über die Schleifkontakte 78 und 68 miteinander verbindet. Der Schiebeschalter 11 befindet sich in der in Fig. 1 dargestell¬ ten Position in der Raststellung "0", das heißt der Motor ist ausgeschaltet, und der VorwahlSchalter 60 befindet sich in der Raststellung "1", entsprechend der kürzest einstellbaren Haar¬ länge. Wird nun der Schiebeschalter von der Raststellung "0" auf die Raststellung "1" hochgeschoben, schaltet sich der Motor ein, da nun der Schleifkontakt 68 mit der Leiterbahn 67 in Verbindung steht.The slide switch 11 is provided with two sliding contacts 68 and 78, one sliding contact 78 sliding over the conductor 77 of a printed circuit board 76 fixed in the housing and the other sliding contact 68 sliding over the conductor 67 of the printed circuit board 66 of the preselection slide 60. The two sliding contacts 68 and 78 are connected to one another in the slide switch 11. The upper end of the conductor track 77 is fixed to the motor M and the upper end of the conductor track 67 is connected via a sliding contact 69. Since the conductor track 77 of the fixed circuit board 76 is connected to a pole of the voltage source, the motor M is switched on when the slide switch 11 connects the two conductor tracks 77 and 67 to one another via the sliding contacts 78 and 68. The slide switch 11 is in the position shown in FIG. 1 in the locking position "0", that is to say the motor is switched off, and the preselection switch 60 is in the locking position "1", corresponding to the shortest hair length that can be set. If the slide switch is now pushed up from the locking position "0" to the locking position "1", the motor switches on, since the sliding contact 68 is now connected to the conductor track 67.
Wäre der VorwahlSchieber 60 auf die Raststellung "4" (strich-punktiert eingezeichnet) eingestellt, was hier der grö߬ ten einstellbaren Haarlänge entspricht, würde der Schleifkontakt 68 mit der Leiterbahn 67 erst in Berührung kommen, das heißt den Motor erst einschalten, wenn der Schiebeschalter 11 ebenfalls in die Raststellung "4" hochgeschoben ist.If the preselection slide 60 were set to the locking position "4" (dash-dotted lines), which corresponds to the largest adjustable hair length here, the sliding contact 68 would only come into contact with the conductor track 67, that is to say only switch on the motor when the Slide switch 11 is also pushed into the locking position "4".
Auf diese Weise ist gewährleistet, daß sich die Haarschneidema¬ schine erst dann in Betrieb setzt, wenn der Schiebeschalter (und mit diesem der aufgesetzte Distanzkamm) die mit dem VorwahlSchie¬ ber markierte Rastposition erreicht hat. Diese Lösung hat den Vorteil, daß die Haare nicht aus Versehen kürzer als vorgewählt geschnitten werden können. Außerdem funktioniert die Haarschnei¬ demaschine wie bisher bei allen eingestellten Haarlängen, wenn der VorwahlSchieber 60 in der Rastposition "1" steht.In this way it is ensured that the hair clipping machine is only put into operation when the slide switch (and with it the attached distance comb) has reached the latching position marked with the preselector slide. This solution has the advantage that the hair cannot be cut shorter than selected by mistake. In addition, the hair clipper works as before with all set hair lengths when the preselection slide 60 is in the locking position "1".
Bei einer anderen Lösung kann die Leiterbahn 67 auf der Leiter¬ platte 66 auch so kurz vorgesehen werden, daß der Schleifkontakt 68 nur in einer einzigen Raststellung des VorwahlSchiebers 60 mit der Leiterbahn in Berührung kommt, so daß die Haarschneidema¬ schine nur in dieser einzigen, vorgewählten Raststellung anläuft. In another solution, the conductor track 67 can also be provided on the printed circuit board 66 so short that the sliding contact 68 only comes into contact with the conductor track in a single latching position of the preselection slide 60, so that the hair clipper only in this single, preselected rest position starts.
