Ein aus der oberen Gehäuseseite herausragendes Antriebselement überträgt die Antriebsbewegung auf die Schneidklinge. Im Tragelement ist ein von einem Federelement beaufschlagtes Reibungselement derart angeordnet, daß dieses zur Anlage an die obere Gehäuseschale des Gehäuses der Haarschneidemaschine gelangt, um mittels einer vorgesehenen Reibung den Scherkopf in irgendeiner Schwenkstellung zu halten.From US 1 997 096 a hair clipper of the type mentioned is known with one pivoted for shaving and trimming in appropriate positions Cutting head, consisting of a swivel mounted in a cam control Carrying element and a cutting comb with only one row of cutting teeth and Cutting blade, which is in contact with the by means of a spring leaf resting on the support element Cutting comb is held.

In the support element is one of one Spring element acted upon friction element arranged such that this to the system gets to the upper housing shell of the housing of the hair clipper to hold the shaving head in any pivoted position by means of an intended friction.

Aus der GB 2 294 230 ist eine Haarschneidemaschine mit einem in beliebige Richtungen schwenkbar gelagerten Schneidkopf bekannt, dessen Schwenkbarkeit über eine Kugelgelenkverbindung vom Gehäuse zum Schneidkopf gewährleistet ist. Der aus einem Tragelement und einem Gehäusedeckel zusammengesetzte Schneidkopf weist einen Schneidkamm und eine Schneidklinge mit jeweils zwei parallel zueinander verlaufend vorgesehenen Schneidzahnreihen auf, die jedoch derart im Schneidkkopf angeordnet sind, daß nur eine der zusammenwirkenden Schneidzahnreihen von Schneidkamm und Schneidklinge aus diesem Gehäuse herausragt. Um die zweite Schneidzahnreihe zum Einsatz zu bringen, muß der Schneidkopf geöffnet werden, so daß Schneidkamm und Schneidklinge innerhalb des Schneidkopfes um 180° gewendet werden können.From GB 2 294 230 is a hair clipper with one in any direction pivotally mounted cutting head known, the pivotability via a ball joint from the housing to the cutting head is guaranteed. The one from a support element and a cutting head composed of a housing cover has a cutting comb and a cutting blade each provided with two parallel to each other Rows of cutting teeth, which are however arranged in the cutting head in such a way that only one the interacting rows of cutting teeth of the cutting comb and cutting blade from this Housing protrudes. To use the second row of cutting teeth, must the cutting head can be opened so that the cutting comb and cutting blade within the Cutting head can be turned through 180 °.

Aufgabe der Erfindung ist es, eine Haarschneidemaschine der eingangs genannten Art hinsichtlich der Funktion zu verbessern und die Handhabung zu erleichtern.The object of the invention is to provide a hair clipper of the type mentioned above improve function and ease of use.

Nach der Erfindung wird diese Aufgabe bei einer Haarschneidemaschine der eingangs genannten Art durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Die Erfindung weist mehrere Vorteile auf. Einer der Vorteile ist darin zu sehen, daß mittels dem als Gehäuseschale ausgebildeten Tragelement die am Schneidkopf für den Antrieb der Schneidklinge vorgesehenen Bauelemente wie z.B. Lagerbock, Schneidklingenträger mit Kupplungselementen sowie auch Verriegelungsvorrichtung und Rasteinrichtung weitgehend eingekapselt werden, um einen direkten Zugang von abgeschnittenen Haaren in diesen Antriebsbereich zu verhindern. Die Gehäuseschale ermöglicht auch die Anordnung einer Verriegelungseinrichtung zur Befestigung und Abnahme des Schneidkopfes zum Zwecke der Reinigung und Wartung und erleichtert demzufolge auch dessen Austauschbarkeit.According to the invention, this object is achieved in a hair clipper of the type mentioned Type solved by the features specified in the characterizing part of claim 1. The Invention has several advantages. One of the advantages is to be seen in that designed as a housing shell support element on the cutting head for driving the Components provided for the cutting blade, e.g. Bearing block, cutting blade holder with Coupling elements as well as locking device and locking device largely are encapsulated for direct access of cut hair into this drive area to prevent. The housing shell also enables the arrangement of a locking device for fastening and removing the cutting head for the purpose of Cleaning and maintenance and therefore also facilitates its interchangeability.

Ein weiterer wesentlicher Vorteil der Erfindung ergibt sich aus der geometrischen Formgestaltung der an den Gabelelementen des Gehäuses schwenkbar gelagerten Gehäuseschale sowie der benachbarten Gehäusewand des Gehäuses. Die nach der Erfindung vorgesehene äußere Kontur der Gehäuseschale gewährleistet eine relativ enge Anpassung der inneren Kontur der Gehäusewand des Gehäuses über den ingesamt vorgesehenen Schwenkbereich der Gehäuseschale. Der Abstand zwischen der äußeren Kontur der Gehäuseschale und der inneren Kontur der Gehäusewand des Gehäuses kann derart gering bemessen werden, daß einerseits eine reibungslose Schwenkbewegung der Gehäuseschale gewährleistet und andererseits ein Eindringen von abgeschnittenen Haaren in das Innere des Gehäuses weitgehend ausgeschlossen ist. Ein Zehntel Millimeter Abstand zwischen der Innenkontur der Gehäusewand des Gehäuses und der äußeren Kontur der Gehäuseschale ist bereits ausreichend für eine reibungslose Schwenkbewegung des Schneidkopfes, sowie beispielsweise zur Vermeidung des Eindringens von Haaren in das Innere des Gehäuses.Another important advantage of the invention results from the geometric shape the housing shell pivotally mounted on the fork elements of the housing and the adjacent housing wall of the housing. The provided according to the invention outer contour of the housing shell ensures a relatively tight adjustment of the inner Contour of the housing wall of the housing over the overall swivel range the housing shell. The distance between the outer contour of the housing shell and the inner contour of the housing wall of the housing can be dimensioned so small that on the one hand ensures a smooth swiveling movement of the housing shell and on the other hand penetration of cut hair largely into the interior of the housing is excluded. A tenth of a millimeter distance between the inner contour of the housing wall of the housing and the outer contour of the housing shell is already sufficient for a smooth swiveling movement of the cutting head, as well as for example to prevent hair from entering the inside of the housing.

Die Zuordnung von zwei Schneidklingen zu einem Schneidkamm ermöglicht in vorteilhafter Weise eine unterschiedliche Ausbildung der von den Zähnen des Schneidkammes und der beiden Schneidklingen gebildeten Schneidzahnreihen, beispielsweise in der Weise, daß die Erstreckungslänge einer Schneidzahnreihe wesentlich geringer als die Erstreckungslänge der anderen Schneidzahnreihe ausgebildet werden kann. Derartige unterschiedliche Ausbildungen gewährleisten einen optimalen Einsatz der Haarschneidemaschine durch Inbetriebnahme der für den jeweiligen Schneidvorgang geeigneten Schneidzahnreihe. Schneidvorgänge in schwer zugänglichen Bereichen lassen sich beispielsweise mit einer Schneidzahnreihe geringerer Erstreckungslänge wesentlich leichter und einfacher schneiden als mit einer größeren bzw. relativ großen Erstreckungslänge. Schneidzahnreihen mit größeren Erstrekkungslängen hingegen eignen sich beispielsweise besonders zum Konturenschneiden.The assignment of two cutting blades to a cutting comb advantageously enables Way a different design of the teeth of the cutting comb and the two cutting blades formed rows of cutting teeth, for example in such a way that the Extension length of a row of cutting teeth is considerably less than the extension length the other row of cutting teeth can be formed. Such different training ensure optimal use of the hair clipper by commissioning the row of cutting teeth suitable for the respective cutting process. cutting operations in areas that are difficult to access, for example, with a row of cutting teeth cut shorter extension length much easier and easier than with one larger or relatively large extension length. Rows of incisors with larger extension lengths on the other hand, for example, are particularly suitable for contour cutting.

Bei dem Ausführungsbeispiel nach Fig. 8 verläuft die Schwenkachse Z durch die Mitte des Abstandes A, den die Vorderwand 111 und die Rückwand 112 zueinander aufweisen. Da die jeweiligen Kegelmäntel KM1 und KM2 an die jeweilige Erstreckungslänge L20 und L10 der Schneidzahnreihen 40 und 41 bezüglich ihrer geometrischen Ausbildung angepaßt sind, ergibt sich ein stufenförmiger Absatz 37 vom Kegelmantel KM1 zum Kegelmantel KM2. In der Anpassung in diese geometrische Formgestaltung der Gehäuseschale 5 ist an den Gabelenden 6 und 7 auf der dem Kegelmantel KM1 und KM2 benachbarten Seite jeweils ein Absatz 36 vorgesehen, derart, daß die Gehäusewand 110 insgesamt eine Innenkontur aufweist, die im wesentlichen parallel zur äußeren Kontur der Wand der Gehäuseschale 5 entspricht.8, the pivot axis Z runs through the center of the Distance A that the front wall 111 and the rear wall 112 have each other. Since the respective cone shells KM1 and KM2 to the respective extension length L20 and L10 of the Rows of cutting teeth 40 and 41 are adapted with regard to their geometric design, there is a step-shaped shoulder 37 from the conical jacket KM1 to the conical jacket KM2. In the adaptation to this geometric shape of the housing shell 5 is at the fork ends 6 and 7 on the side adjacent to the conical surface KM1 and KM2 Paragraph 36 provided such that the housing wall 110 has an overall inner contour, which corresponds essentially parallel to the outer contour of the wall of the housing shell 5.

Figuren 9 und 10 zeigen einen Schnitt durch eine Haarschneidemaschine HSM nach den Figuren 8 und 8A mit dem Unterschied, daß bei der Ausführungsform nach Fig. 9 die Vorderwand 111 mit der Rückwand 112 durch ein schalenartig ausgebildetes Wandelement 20 verbunden ist, während bei der Ausführungsform nach Fig. 10 zwischen Vorderwand 111 und Rückwand 112 kein Wandelement 20 vorgesehen ist. Die Schnittdarstellung des Schneidkopfes S macht deutlich, daß die Mantelfläche M1 mit dem Radius R1 gleich der Mantelfläche M2 mit dem Radius R2 ausgebildet ist.Figures 9 and 10 show a section through a hair clipper HSM according to the Figures 8 and 8A with the difference that in the embodiment of FIG. 9, the front wall 111 with the rear wall 112 through a shell-like wall element 20 is connected, while in the embodiment according to FIG. 10 between front wall 111 and rear wall 112 no wall element 20 is provided. The sectional view of the Cutting head S makes it clear that the lateral surface M1 is equal to the radius R1 Shell surface M2 is formed with the radius R2.

Die Figuren 11 und 12 zeigen jeweils einen um eine Schwenkachse Z schwenkbar gelagerten Schneidkopf S und eine Schnittdarstellung des oberen Teiles des Gehäuses 1. Die Schwenkachse ist nicht auf der Mitte des Abstandes A, den die Vorderwand 111 und die Rückwand 112 zueinander einnehmen vorgesehen, sondern in einem kleineren Abstand B zur Vorderwand 111 bzw. in einem größeren Abstand C zur Rückwand 112. Die Wand der Gehäuseschale 5 ist bei diesen Ausführungsformen durch die Mantelfläche M1 mit dem Radius R1 und durch die Mantelfläche M2 mit dem Radius R2 von zwei zusammengesetzten Sektoren S1, S2 von Kreiszylindern Z1 und Z2 gebildet. Ausgehend von der Größe eines Halbkreises ist der Sektorwinkel des Sektors SK1 mit dem Radius R1 kleiner als 90° ausgebildet, während der Sektor SK2 mit dem Radius R2 größer als 90° ausgebildet ist. Durch eine derartige Ausbildung und Zusammensetzung von zwei Sektoren SK1 und SK2 von zwei Kreiszylindem Z1 und Z1 mit den Radien R1 und R2 ergibt sich zwangsläufigerweise eine unterschiedliche geometrische Ausbildung der Kegelmäntel KM, und KM2 der Stimseitenwände 24 und 25. Die Vorderwand 111 endet in einem relativ geringen Abstand, der als Spalt 38 in den Figuren 11 und 12 gekennzeichnet ist. Die Größe des Spaltes 38 ist derart zu bemessen, daß lediglich eine reibungslose Schwenkbewegung der Schneideinheit S um die Schwenkachse Z gewährleistet ist.FIGS. 11 and 12 each show a cutting head S which is pivotably mounted about a pivot axis Z and a sectional illustration of the upper part of the housing 1. The pivot axis is not provided at the center of the distance A which the front wall 111 and the rear wall 112 are in relation to one another, but instead at a smaller distance B from the front wall 111 or at a greater distance C from the rear wall 112. In these embodiments, the wall of the housing shell 5 is of two composite sectors S1 due to the lateral surface M1 with the radius R1 and through the lateral surface M2 with the radius R2 , S2 formed by circular cylinders Z1 and Z2. Starting from the size of a semicircle, the sector angle of sector SK1 with radius R1 is less than 90 °, while sector SK2 with radius R2 is greater than 90 °. Such a design and composition of two sectors SK1 and SK2 of two circular cylinders Z1 and Z1 with the radii R1 and R2 inevitably results in a different geometrical design of the cone shells KM and KM 2 of the face side walls 24 and 25. The front wall 111 ends in one relatively small distance, which is identified as gap 38 in Figures 11 and 12. The size of the gap 38 is to be dimensioned such that only a smooth pivoting movement of the cutting unit S about the pivot axis Z is ensured.

Bei der Ausführungsform nach Fig. 11 sind die Vorderwand 111 und die Rückwand 112 über ein schalenförmig ausgebildetes, stufenartig abgesetztes Wandelement 20 miteinander verbunden. Der stufenförmige Absatz 37 ist in einem derartigen Winkel zu der die Schwenkachse Z schneidenden vertikalen Achse V vorgesehen, daß eine ungehinderte Schwenkbewegung des Schneidkopfes S innerhalb dessen vorgegebenen Schwenkbereiches, der beispielsweise durch Anschläge 90, 91, 92, 93 oder durch Anlage an einem Absatz 36 bestimmt ist, erfolgen kann.11, the front wall 111 and the rear wall 112 are over a shell-shaped, stepped wall element 20 connected to each other. The stepped shoulder 37 is at such an angle to the pivot axis Z intersecting vertical axis V provided that an unobstructed pivoting movement of the cutting head S within its predetermined swivel range, for example determined by stops 90, 91, 92, 93 or by abutment on a paragraph 36 is can be done.

Fig. 13 zeigt eine perspektivische Darstellung des oberen Teiles eines Gehäuses 1 sowie eines Schneidkopfes S der Ausführungsform nach Fig. 11. Bedingt durch die unterschiedlichen Größen der Radien R1 und R2 der Mantelflächen M1 und M2 der zusammengesetzten Sektoren SK1 und SK2 der Kreiszylinder Z1 und Z2 ergibt sich ein stufenförmiger Übergang dieser Sektoren SK1, SK2, der beispielsweise als Anschlag an einem stufenförmigen Absatz 36 des Wandelementes 20 zur Begrenzung der Schwenkbewegung des Schneidkopfes S verwendet werden kann.Fig. 13 shows a perspective view of the upper part of a housing 1 and of a cutting head S of the embodiment according to FIG. 11. Due to the different Sizes of the radii R1 and R2 of the lateral surfaces M1 and M2 of the composite Sectors SK1 and SK2 of the circular cylinders Z1 and Z2 result in a step-like transition of these sectors SK1, SK2, for example as a stop on a step-shaped paragraph 36 of the wall element 20 to limit the pivoting movement of the cutting head S. can be used.

Bei der Ausführungsform nach Fig. 14 ist mangels eines Wandelementes 20 der stufenförmige Absatz 36 an der Innenseite der Rückwand 112 vorgesehen. In Anpassung an die äußere Kontur der Gehäuseschale 5 weisen die zur Gehäuseschale 5 benachbarten Wände des Gehäuses 1 eine Innenkontur auf, die im wesentlichen parallel zur äußeren Kontur der Mantelfläche M1 und M2 sowie der Kegelmäntel KM1 und KM2 entsprechen. Die auf der Innenseite der Gabelelemente 6 und 7 jeweils vorhandenen Innenflächen 50 und 51 sind in ihrer Form entsprechend der Form der äußeren Flächen der Kegelmäntel KM1 und KM2 ausgebildet.In the embodiment according to FIG. 14, the step-shaped is lacking a wall element 20 Paragraph 36 provided on the inside of the rear wall 112. Adapting to the outside Contour of the housing shell 5 have the walls adjacent to the housing shell 5 of the housing 1 has an inner contour which is substantially parallel to the outer contour of the The lateral surface M1 and M2 as well as the conical shells KM1 and KM2 correspond. The one on the Inside of the fork elements 6 and 7, the respective inner surfaces 50 and 51 are shown in their shape corresponds to the shape of the outer surfaces of the conical shells KM1 and KM2 educated.

Die Figuren 15 bis 18 zeigen eine Sicht auf das obere Ende der aus einer Vorderwand 111, einer Rückwand 112 und zwei Seitenwänden 113 und 114 bestehenden Gehäusewand 110 des Gehäuses 1, der Haarschneidemaschine HSM ohne Schneidkopf S und ohne Gehäuseschale 5, jedoch mit einem das Innere des Gehäuses 1 abschließenden Wandelement 20, das von dem Antriebselement 12 durchsetzt ist.FIGS. 15 to 18 show a view of the upper end of a front wall 111, a rear wall 112 and two side walls 113 and 114 existing housing wall 110 of the housing 1, the hair clipper HSM without cutting head S and without the housing shell 5, but with a wall element 20 that closes off the interior of the housing 1, which is penetrated by the drive element 12.

Bei den Ausführungsformen nach den Figuren 15 bis 16 verläuft die Schwenkachse Z auf der Mitte des Abstandes A, den die Vorderwand 111 und die Rückwand 112 zueinander einnehmen. Die Abstände B und C sind sonach gleich groß ausgebildet. Die Innenkontur der durch die Vorderwand 111, Rückwand 112 und die Seitenwände 113 und 114 gebildeten Gehäusewand 110 ist bei der Ausführungsform nach Fig. 15 zumindest an Wandrändem dieser Wände geradlinig ausgebildet.In the embodiments according to FIGS. 15 to 16, the pivot axis Z extends the center of the distance A that the front wall 111 and the rear wall 112 occupy each other. The distances B and C are therefore of the same size. The inner contour of the formed by the front wall 111, rear wall 112 and the side walls 113 and 114 In the embodiment according to FIG. 15, housing wall 110 is at least on wall edges of these walls are straight.

Fig. 16 zeigt eine Ausführungsform bei der die Innenkontur sämtlicher Wände der Gehäusewand 110 endseitig bogenförmig ausgebildet ist. Bedingt durch die Anpassung der Innenkontur der Gehäusewand 110 an die Außenkontur der Gehäuseschale 5 ergeben sich durch die unterschiedlichen Erstreckungslängen der Mantelflächen M1 und M2 - siehe Fig. 13 und 14 - stufenförmige Absätze 36 an den Seitenwänden 113 und 114 - siehe Fig. 15 - sowie ein zusätzlicher stufenförmiger Absatz 36 an der Rückwand 112 der Ausführungsformen nach Fig. 16.16 shows an embodiment in which the inner contour of all the walls of the housing wall 110 is arch-shaped at the end. Due to the adjustment of the inner contour the housing wall 110 on the outer contour of the housing shell 5 result from the different extension lengths of the lateral surfaces M1 and M2 - see FIGS. 13 and 14 - step-shaped shoulders 36 on the side walls 113 and 114 - see Fig. 15 - and a additional step-shaped heel 36 on the rear wall 112 of the embodiments Fig. 16.

Optional ist die Schwenkachse Z nicht auf der Mitte des Abstandes A den die Vorderwand 111 und die Rückwand 112 zueinander einnehmen, vorgesehen, sondern in einem kleineren Abstand B zur Vorderwand 111 bzw. in einem größeren Abstand C zur Rückwand 112. Unter Berücksichtigung der unterschiedlichen Erstreckungslängen der Mantelflächen M1 und M2 einer Gehäuseschale 5 - siehe Fig. 13 und 14 - ergibt sich eine Innenkontur für die Seitenwände 113 und 114 der Gehäusewand 110 mit zur Schwenkachse Z ausgerichteten Kegelwinkel α1 und α2 unterschiedlicher Größe. Demzufolge ist auch der eine Gehäusefläche bildende stufenförmige Absatz 36 an der Vorderwand 111, der teilweise in die Seitenwand 113 und 114 übergeht, wesentlich stärker ausgebildet, als dies bei den Ausführungsformen nach den Fig. 15 bis 17 der Fall ist.Optionally, the pivot axis Z is not at the center of the distance A from the front wall 111 and the rear wall 112 to each other, provided, but in a smaller one Distance B to the front wall 111 or at a greater distance C to the rear wall 112. Below Taking into account the different extension lengths of the lateral surfaces M1 and M2 a housing shell 5 - see FIGS. 13 and 14 - results in an inner contour for the side walls 113 and 114 of the housing wall 110 with a cone angle aligned with the pivot axis Z. α1 and α2 of different sizes. Accordingly, it is also a housing surface forming step-shaped heel 36 on the front wall 111, which is partially in the side wall 113 and 114 merges, formed much stronger than in the embodiments 15 to 17 is the case.

Die Ausführungsformen nach den Fig. 17 und 18 zeigen Innenkonturen von Gehäusewänden 110 die geradlinig ausgebildet sind, denen entsprechend geformte äußere Konturen der Gehäuseschale 5 zugeordnet sind.The embodiments according to FIGS. 17 and 18 show inner contours of housing walls 110 which are formed in a straight line, to which the correspondingly shaped outer contours of the Housing shell 5 are assigned.
