Description

Die vorliegende Erfindung betrifft eine Schneidsatzaufnahme für eine Haarschneidemaschine gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a cutting attachment for a hair clipper according to the preamble of patent claim 1.

Eine entsprechende Schneidsatzaufnahme für eine Haarschneidemaschine weist eine Aufnahmebasis, die an der Haarschneidemaschine befestigbar ist, und einen schwenkbar an der Aufnahmebasis gelagerten Aufnahmeschenkel auf, wobei an dem Aufnahmeschenkel ein auswechselbarer Schneidsatz anordenbar ist. Derartige Schneidsatzaufnahmen werden typischerweise für Haarschneidemaschinen, wie sie vorwiegend in der Tierpflege verwendet werden, eingesetzt und dienen zur Aufnahme eines an der Haarschneidemaschine anordenbaren auswechselbaren Schneidsatzes. Die Schneidsatzaufnahmen sind dafür in Form eines Klappmechanismus ausgebildet, wobei der Schneidsatz an dem Aufnahmeschenkel der Schneidsatzaufnahme anordenbar, z. B. auf diesen aufschiebbar, ist und dann zusammen mit dem Aufnahmeschenkel in Richtung der Aufnahmebasis an die Haarschneidemaschine angeklappt und dort bspw. durch Verrasten fixiert wird.A corresponding cutting attachment for a hair clipper has a receiving base which can be fastened to the hair cutting machine, and a receiving leg which is pivotably mounted on the receiving base, wherein an exchangeable cutting set can be arranged on the receiving leg. Such sets of cutters are typically used for hair clippers, such as those used primarily in animal care, and serve to receive a replaceable cutting set which can be arranged on the hair clipping machine. The cutting set recordings are designed for this purpose in the form of a folding mechanism, wherein the cutting set can be arranged on the receiving leg of the cutting set receptacle, for. B. slid on this is, and then folded together with the receiving leg in the direction of the receiving base to the hair clipper and there, for example, is fixed by latching.

Derartige Schneidsatzaufnahmen sind aus der US 5 092 048 A oder US 2 182 597 A bekannt.Such Schneidsatzaufnahmen are from the US 5 092 048 A or US 2,182,597 A. known.

Bei den bekannten Schneidsatzaufnahmen erfolgt ein derartiges Verrasten auch dann, wenn die Schneidsatzaufnahme ohne eingesetzten Schneidsatz versehentlich zugeklappt wird, d. h. wenn der Aufnahmeschenkel ohne daran angeordneten Schneidsatz in Richtung der Aufnahmebasis geschwenkt und dort verrastet wird. Die bisherigen Schneidsatzaufnahmen können, wenn sie ohne einen daran angeordneten Schneidsatz zugeklappt wurden, nur noch mit Hilfe eines Werkzeuges wieder geöffnet werden und haben dadurch den Nachteil, dass ein weiterer Einsatz der Haarschneidemaschine nicht möglich ist, wenn kein geeignetes Werkzeug zur Verfügung steht oder die Handhabung desselben nicht beherrscht wird. Darüber hinaus besteht bei mangelnder Beherrschung des entsprechenden Werkzeuges ein erhöhtes Verletzungsrisiko.In the known cutting set recordings such locking takes place even when the cutting set without accidentally inserted cutting set is accidentally closed, ie when the receiving leg is pivoted without arranged thereon cutting set in the direction of the receiving base and locked there. The previous cutting set recordings, if they were closed without a cutting set arranged thereon, can only be opened again with the aid of a tool and thus have the disadvantage that further use of the hair cutting machine is not possible if no suitable tool is available or handling same not is mastered. In addition, there is an increased risk of injury in the case of a lack of control of the corresponding tool.

Es ist die Aufgabe der vorliegenden Erfindung, die vorstehend benannten Probleme zu beseitigen.It is the object of the present invention to eliminate the above-mentioned problems.

Erfindungsgemäß wird dies durch eine Schneidsatzaufnahme mit den Merkmalen des Patentanspruchs 1 erreicht.This is achieved by a cutting set recording with the features of claim 1 according to the invention.

Eine erfindungsgemäße Schneidsatzaufnahme für eine Haarschneidemaschine weist eine Aufnahmebasis, die an der Haarschneidemaschine befestigbar ist, und einen schwenkbar an der Aufnahmebasis gelagerten Aufnahmeschenkel auf, an dem ein auswechselbarer Schneidsatz anordenbar ist, wobei an der Schneidsatzaufnahme ein zwischen einer Schwenkstellung und einer Blockierstellung bewegbares Sperrelement vorgesehen ist, das geeignet ausgebildet ist, eine Schwenkbewegung des Aufnahmeschenkels in Richtung der Aufnahmebasis ohne an dem Aufnahmeschenkel angeordneten Schneidsatz zu blockieren.A cutting attachment according to the invention for a hair cutting machine has a receiving base, which can be fastened to the hair cutting machine, and a receiving leg mounted pivotably on the receiving base, on which a replaceable cutting set can be arranged, wherein a blocking element movable between a pivoting position and a blocking position is provided on the cutting attachment , which is adapted to block a pivoting movement of the receiving leg in the direction of the receiving base without arranged on the receiving leg cutting set.

Die erfindungsgemäße Ausgestaltung hat den Vorteil, dass durch ein entsprechend ausgestaltetes Sperrelement ein versehentliches Zuklappen der Schneidsatzaufnahme ohne einen daran angeordneten Schneidsatz verhindert wird und so der Einsatz eines entsprechendes Werkzeuges zum Öffnen der Schneidsatzaufnahme vermieden werden kann. Die angesprochenen Verletzungsrisiken sowie die Notwendigkeit des Vorhaltens eines entsprechenden Werkzeuges werden damit vermieden.The embodiment of the invention has the advantage that accidentally closing the cutting set without a arranged thereon cutting set is prevented by a suitably ausgestaltetes locking element and thus the use of a corresponding tool for opening the Schneidsatzaufnahme can be avoided. The mentioned injury risks as well as the necessity of having a suitable tool are thus avoided.

Eine besonders günstige Handhabung wird erreicht, wenn das Sperrelement geeignet ausgebildet ist, dass es von dem Schneidsatz beim Anordnen an dem Aufnahmeschenkel in die Schwenkstellung überführt wird.A particularly favorable handling is achieved when the blocking element is designed to be suitable that of the Cutting set when placing on the receiving leg is transferred to the pivot position.

Auf diese Weise wird erreicht, dass eine Überführung des Sperrelementes durch bspw. ein Aufstecken des Schneidsatzes auf den Aufnahmeschenkel bewirkt wird. Ein Anklappen kann so ohne zusätzliche Handgriffe freigegeben werden, während ohne an dem Aufnahmeschenkel angeordneten Schneidsatz die Schwenkbewegung blockiert wird. Gegenüber einer Ausgestaltung, bei der das Sperrelement manuell, bspw. über einen Entriegelungshebel, in die Schwenkstellung überführt wird, besteht der Vorteil, dass ein versehentliches Anklappen der Schneidsatzaufnahme ohne daran angeordneten Schneidsatz nicht möglich ist.In this way it is achieved that a transfer of the blocking element is effected by, for example, a plugging of the cutting set on the receiving leg. Folding can be released without additional manipulation, while without arranged on the receiving leg cutting set the pivoting movement is blocked. Compared to an embodiment in which the blocking element is manually, for example. Via a release lever, transferred to the pivot position, there is the advantage that an accidental folding of the cutting set without a arranged thereon cutting set is not possible.

Das Sperrelement kann bspw. an einer Schwenkachse der Schneidsatzaufnahme gelagert sein.The blocking element may, for example, be mounted on a pivot axis of the cutting attachment.

Eine besonders sichere Ausgestaltung kann erreicht werden, wenn das Sperrelement in Richtung der Blockierstellung federbelastet ist.A particularly secure configuration can be achieved if the blocking element is spring-loaded in the direction of the blocking position.

Durch eine Federbelastung des Sperrelementes in Richtung der Blockierstellung wird erreicht, dass das Sperrelement ohne eine darauf einwirkende Kraft immer in die Blockierstellung überführt wird. Nur sofern durch bspw. ein Aufschieben des Schneidsatzes auf den Aufnahmeschenkel eine Kraft auf das Sperrelement ausgeübt wird, wird es aus der Blockierstellung in die Schwenkstellung überführt und damit ein Anklappen des Aufnahmeschenkels mit daran angeordnetem Schneidsatz an die Aufnahmebasis freigegeben.By a spring load of the blocking element in the direction of the blocking position is achieved that the blocking element is always transferred without a force acting thereon in the blocking position. Only if, for example, by pushing the cutting set on the receiving leg, a force is exerted on the locking element, it is transferred from the blocking position in the pivot position, thus releasing a tilting of the receiving leg with arranged cutting set to the receiving base.

Das Sperrelement kann bspw. als Sperrriegel ausgebildet sein.The blocking element may, for example, be designed as a locking bolt.

Ein solcher Sperrriegel kann an der Schneidsatzaufnahme verschiebbar, bspw. parallel zu dem Aufnahmeschenkel verschiebbar, gelagert sein.Such a locking bolt can be slidably mounted on the cutting attachment, for example, parallel to the receiving leg slidably mounted.

Wenn der Sperrriegel parallel zu dem Aufnahmeschenkel verschiebbar gelagert ist, kann erreicht werden, dass dieser durch ein Aufschieben des Schneidsatzes auf den Aufnahmeschenkel in die Schwenkstellung überführt wird. Dadurch, dass eine Aufschiebbewegung des Schneidsatzes auf den Aufnahmeschenkel in der Regel parallel zu dem Aufnahmeschenkel ausgeführt wird, wird erreicht, dass diese lineare Bewegung direkt auf den Sperrriegel übertragbar ist und so eine Änderung der Bewegungsrichtung und damit verbundene Gefahren eines Verklemmens vermieden werden.If the locking bolt is mounted displaceably parallel to the receiving leg, it can be achieved that this is transferred by sliding the cutting set on the receiving leg in the pivot position. Characterized in that a Aufschiebbewegung the cutting set is carried out on the receiving leg usually parallel to the receiving leg, it is achieved that this linear movement is directly transferable to the locking bar and so a change in the direction of movement and associated risks of jamming can be avoided.

Der Sperrriegel kann bspw. derart ausgebildet sein, dass in der Blockierstellung eine Sperrstufe des Sperrriegels an der Aufnahmebasis anläuft und so eine Schwenkbewegung des Aufnahmeschenkels blockiert. Die Aufnahmebasis weist bevorzugt eine Ausnehmung zur Aufnahme des Sperrriegels in der Schwenkstellung auf.The locking bolt may, for example, be designed such that in the blocking position, a locking stage of the locking bolt starts against the receiving base and thus blocks a pivoting movement of the receiving leg. The receiving base preferably has a recess for receiving the locking bolt in the pivoting position.

Alternativ zu einer Ausgestaltung des Sperrelementes als Sperrriegel kann das Sperrelement auch als sogenannter Sperrwinkel ausgebildet sein.As an alternative to an embodiment of the blocking element as a locking bolt, the blocking element can also be designed as a so-called blocking angle.

Ein solcher Sperrwinkel kann bspw. parallel zu der Schwenkachse verschiebbar gelagert sein.Such a locking angle can, for example, be displaceably mounted parallel to the pivot axis.

Ein parallel zu der Schwenkachse verschiebbar gelagerter Sperrwinkel kann bspw. eine in Aufschieberichtung des Schneidsatzes schräg verlaufende Anlaufkante aufweisen, die eine auf die Schwenkachse zu orientierte Aufschiebebewegung in eine parallel zu der Schwenkachse orientierte Bewegung des Sperrwinkels umwandelt, sodass dieser durch ein Aufschieben des Schneidsatzes in die Schwenkstellung überführbar ist.A locking angle displaceably mounted parallel to the pivot axis may, for example, have a starting edge running obliquely in the sliding direction of the cutting set, which has a sliding movement oriented toward the pivot axis in a parallel direction to the pivot axis oriented movement of the locking angle converts, so that it can be transferred by pushing the cutting set in the pivoting position.

Alternativ kann der Sperrwinkel schwenkbar an der Schneidsatzaufnahme gelagert sein.Alternatively, the locking angle can be pivotally mounted on the Schneidsatzaufnahme.

Durch eine Federbelastung des Sperrelementes in Richtung der Blockierstellung kann außerdem erreicht werden, dass ein Schneidsatz in geöffnetem Zustand der Schneidsatzaufnahme gewissermaßen selbsttätig von dem Aufnahmeschenkel gelöst wird und damit quasi selbsttätig ausgeworfen wird.By a spring load of the blocking element in the direction of the blocking position can also be achieved that a cutting set in the open state of the Schneidsatzaufnahme is effectively released from the receiving leg and thus quasi automatically ejected.

Ein selbsttätiges Öffnen der Schneidsatzaufnahme sowie ein selbsttätiges Auswerfen des Schneidsatzes kann dadurch unterstützt werden, dass der Aufnahmeschenkel in Öffnungsrichtung federbelastet ausgeführt ist.An automatic opening of the Schneidsatzaufnahme and an automatic ejection of the cutting set can be supported, that the receiving leg is designed to be spring loaded in the opening direction.

Wird bei einer derartigen Ausgestaltung eine Verriegelung der Schneidsatzaufnahme geöffnet, so klappt der Aufnahmeschenkel selbsttätig von der Aufnahmebasis ab, wobei bei einer federbelasteten Ausführung des Sperrelementes bei entsprechender Dimensionierung der Feder auch ein selbsttätiger Auswurf des Schneidsatzes erfolgen kann.If, in such an embodiment, a locking of the cutting set receptacle is opened, the receiving leg automatically folds away from the receiving base, whereby with a spring-loaded design of the blocking element with appropriate dimensioning of the spring, an automatic ejection of the cutting set can also take place.

Grundsätzlich muss aber ein Auswerfen des Schneidsatzes nicht zwingend vorgesehen sein, da dafür eine starke Feder nötig wäre, welche das Wiederaufstecken des Schneidsatzes erschweren würde. Idealerweise ist die Federkraft groß genug um das Sperrelement sicher in Sperrstellung zu bewegen, aber klein genug um durch die Schwerkraft eines senkrecht aufgesetzten Schneidsatzes wieder aus der Sperrstellung bewegt zu werden. So sollte der Bediener keine zusätzliche Kraft zum Bewegen des Sperrelements aufbringen müssen, wenn er den Schneidsatz senkrecht aufsetzt.Basically, however, an ejection of the cutting set does not necessarily have to be provided, as this would require a strong spring, which would make the re-insertion of the cutting set more difficult. Ideally, the spring force is large enough to safely move the locking element in the locked position, but small enough to be moved by the gravity of a vertically mounted cutting set again from the locked position. So the operator should not need extra force to move the Apply locking elements when he puts the blade vertically.

Bevorzugterweise wird eine Haarschneidemaschine direkt mit einer Schneidsatzaufnahme mit den vorstehend beschriebenen Merkmalen ausgestattet. Eine solche Haarschneidemaschine wird bevorzugt im Bereich der Tierpflege verwendet.Preferably, a hair clipper is directly equipped with a cutting attachment with the features described above. Such a hair clipper is preferably used in the field of animal care.

Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele unter Bezugnahme auf die beigefügten Figuren eingehend erläutert.The invention will be explained below with reference to two exemplary embodiments with reference to the accompanying figures.

Figur 1 zeigt eine Seitenansicht einer Haarschneidemaschine mit einem Gehäuse 2, an dem vorderseitig ein Schneidsatz 3, bestehend aus einem Scherkamm 4 sowie einem darüber oszillierend antreibbar angeordneten Schermesser 5, angeordnet ist. Eine oszillierende Bewegung des Schermessers 5 ist durch einen in dem Gehäuse 2 angeordneten Antrieb der Haarschneidemaschine erzeugbar. FIG. 1 shows a side view of a hair clipper with a housing 2, on the front side of a cutting set 3, consisting of a shearing comb 4 and an oscillating over this arranged drift blade 5, is arranged. An oscillating movement of the blade 5 is by a in the housing 2 arranged drive the hair clipper generated.

Figur 2 zeigt die Haarschneidemaschine aus Figur 1 mit abgeklapptem Schneidsatz 3. FIG. 2 shows the hair clipper FIG. 1 with folded cutting set 3.

In dieser Darstellung ist besonders gut der Aufbau des Schneidsatzes 3 erkennbar. Das Schermesser 5 ist über eine Schneiddruckfeder 7, die an dem Scherkamm 4 angeordnet ist, mit einem Anpressdruck beaufschlagt, der verhindert, dass sich Haare zwischen vorderseitig an dem Scherkamm 4 und dem Schermesser 5 angeordneten Zähnen verkanten und so zu einer Blockierung des Schneidsatzes 3 führen. Eine Oszillationsbewegung des Antriebes wird über einen Mitnehmer 6 auf das Schermesser 5 übertragen. Der Mitnehmer 6 ist antriebsseitig an dem Schermesser 5 angeordnet und weist einen Eingriff für einen vorderseitig an dem Antrieb angeordneten Zapfen zur Übertragung der Oszillationsbewegung auf.In this illustration, the structure of the cutting set 3 is particularly well recognizable. The shearing blade 5 is acted upon by a cutting pressure spring 7, which is arranged on the shearing comb 4, with a contact pressure, which prevents hair from tilting between the front of the shearing comb 4 and the shearing blade 5 arranged teeth and thus lead to a blockage of the cutting set 3 , An oscillatory movement of the drive is transmitted via a driver 6 on the shearing blade 5. The driver 6 is arranged on the drive side of the shearing blade 5 and has an engagement for a front side arranged on the drive pin for transmitting the oscillatory motion.

In Figur 3 ist eine Schneidsatzaufnahme 1, wie sie in der Haarschneidemaschine aus den Figuren 1 und 2 vorderseitig eingesetzt ist, dargestellt. Figur 3 zeigt eine Schnittdarstellung der Schneidsatzaufnahme 1, sodass deren Aufbau besonders gut erkennbar ist.In FIG. 3 is a Schneidsatzaufnahme 1, as in the hair clipper from the Figures 1 and 2 is inserted on the front side, shown. FIG. 3 shows a sectional view of the Schneidsatzaufnahme 1 so that their structure is particularly easy to see.

Die Schneidsatzaufnahme 1 ist im Wesentlichen aus einer Aufnahmebasis 10, an der ein Aufnahmeschenkel 20 schwenkbar angeordnet ist, gebildet. Der Aufnahmeschenkel 20 ist in Seitenansicht im Wesentlichen L-förmig ausgebildet und über eine Schwenkachse 18 an der Aufnahmebasis 10 schwenkbar gelagert. An der Schwenkachse 18 ist außerdem ein Sperrelement 30 parallel zu dem Aufnahmeschenkel 20 verschiebbar gelagert. Das Sperrelement 30 weist eine U-förmige Führung 34 auf, mit der es die Schwenkachse 18 übergreift und damit entlang des Aufnahmeschenkels 20 verschiebbar ist. Der Aufnahmeschenkel 20 ist rückseitig durch eine an der Aufnahmebasis 10 angeordnete Blattfeder 12 beaufschlagt, die derart bogenförmig ausgeführt ist, dass ein rückseitiger Abschnitt des Aufnahmeschenkels 20 in den Bogenverlauf hineingleitet und so durch die Federbelastung ein Öffnen, d. h. Abklappen, des Aufnahmeschenkels 20 bewirkt. Die Aufnahmebasis 10 weist an der dem Aufnahmeschenkel 20 zugewandten Seite der Aufnahmebasis 10 zu der Schwenkachse 18 hin orientiert eine Anschlagskante 13 auf, an die das Sperrelement 30, das im vorliegenden Beispiel als Sperrriegel 30 ausgebildet ist, in Blockierstellung anschlägt und damit ein Zuklappen der Schneidsatzaufnahme 1 blockieren kann. Der Sperrriegel 30 weist dazu eine Sperrstufe 32 auf, die, wenn sich der Sperrriegel 30 in Blockierstellung befindet, an der Anschlagskante 13 anschlägt.The cutting set holder 1 is essentially formed from a receiving base 10, on which a receiving leg 20 is pivotably arranged. The receiving leg 20 is formed in side view substantially L-shaped and pivotally mounted on the receiving base 10 via a pivot axis 18. On the pivot axis 18, a locking element 30 is also slidably mounted parallel to the receiving leg 20. The blocking element 30 has a U-shaped guide 34, with the it overlaps the pivot axis 18 and is thus displaceable along the receiving leg 20. The receiving leg 20 is acted on the rear side by a arranged on the receiving base 10 leaf spring 12 which is designed arcuate, that a rear portion of the receiving leg 20 slides into the sheet and thus by the spring load opening, ie folding, the receiving leg 20 causes. The receiving base 10 has on the receiving leg 20 facing side of the receiving base 10 to the pivot axis 18 oriented towards a stop edge 13, to which the locking element 30, which is formed in the present example as a locking bolt 30, strikes in blocking position and thus collapse of the Schneidsatzaufnahme 1 can block. The locking bar 30 has for this purpose a locking step 32, which, when the locking bar 30 is in the blocking position, abuts against the stop edge 13.

Der Sperrriegel 30 ist in Figur 3 in zwei unterschiedlichen Positionen dargestellt, wobei eine in vorderseitiger Richtung ausgerückte Position (strichliert dargestellt) die Blockierstellung des Sperrriegels 32 darstellt. Die durchgehend dargestellte Stellung des Sperrriegels 30 stellt eine Zwischenstellung dar, bei der der Sperrriegel 30 in Richtung der Schwenkposition verschoben ist. Die Schwenkposition ist erreicht, sobald eine vordere Kante der Sperrstufe 32 an der Anschlagskante 13 vorbeigleiten kann.The locking bar 30 is in FIG. 3 shown in two different positions, with a disengaged in the front direction position (shown in phantom) represents the blocking position of the locking bar 32. The continuous position of the locking bar 30 represents an intermediate position in which the locking bar 30 is moved in the direction of the pivoting position. The pivoting position is reached as soon as a front edge of the locking stage 32 can slide past the stop edge 13.

Eine Federbelastung des Sperrriegels 30 wird durch eine Druckfeder erreicht, die in die Eingriffsöffnung 36 eingreift und den Sperrriegel 30 damit in vorderseitiger Richtung belastet. Eine solche Druckfeder kann sich bspw. in rückseitiger Richtung an dem L-förmig ausgebildeten Aufnahmeschenkel 20 oder an der Schwenkachse 18 abstützen.A spring load of the locking bolt 30 is achieved by a compression spring which engages in the engagement opening 36 and the locking latch 30 thus loaded in the front-side direction. Such a compression spring may, for example, be supported in the rearward direction on the L-shaped receiving leg 20 or on the pivot axis 18.

Figur 4 zeigt die Schneidsatzaufnahme 1 aus Figur 3 in Draufsicht. Dargestellt ist lediglich die Aufnahmebasis 10 mit der daran angeordneten Schwenkachse 18, wobei der Aufnahmeschenkel 20 zur besseren Darstellung des Blockiermechanismus weggelassen ist. FIG. 4 shows the Schneidsatzaufnahme 1 from FIG. 3 in plan view. Shown is merely the receiving base 10 with the pivot axis 18 arranged thereon, wherein the receiving leg 20 is omitted for better representation of the blocking mechanism.

In dieser Draufsicht ist gezeigt, dass im vorliegenden Ausführungsbeispiel zwei Sperrriegel 30 vorgesehen sind, die voneinander beabstandet an der Schwenkachse 18 angeordnet sind. Auf diese Weise kann eine gleichmäßige Kraftverteilung auf die Aufnahmebasis für den Fall erreicht werden, dass trotz in Blockierstellung befindlicher Sperrriegel 30 ein Zuklappen der Schneidsatzaufnahme versucht wird. Darüber hinaus wird ein Zuklappen der Schneidsatzaufnahme 1 bei schief eingesetztem Schneidsatz 3 verhindert, sodass eine derartige Fehlbedienung ausgeschlossen wird.In this plan view, it is shown that in the present exemplary embodiment two locking bars 30 are provided, which are arranged at a distance from one another on the pivot axis 18. In this way, a uniform force distribution can be achieved on the receiving base in the event that, despite blocking position located in the blocking position 30, a collapse of the Schneidsatzaufnahme is attempted. In addition, a collapse of the Schneidsatzaufnahme 1 is prevented in obliquely inserted cutting set 3, so that such incorrect operation is excluded.

Die Sperrriegel 30 sind in Figur 4 in Blockierstellung dargestellt. Dies ist daran zu erkennen, dass eine vorderseitige Kante der Sperrriegel 30 mit der Anschlagskante 13 der Aufnahmebasis 10 überlappt und damit an dieser anschlägt. Zur Aufnahme der Sperrriegel 30 in der Schwenkposition weist die Aufnahmebasis 10 zwei Ausnehmungen 19 auf, in die die Sperrriegel 30, wenn sie durch den Schneidsatz 3 in Richtung der Schwenkachse 18 geschoben werden, eintauchen können, sodass eine Schwenkbewegung des Aufnahmeschenkels 20 freigegeben wird.The locking bolts 30 are in FIG. 4 shown in blocking position. This can be seen in that a front edge of the locking bar 30 overlaps with the stop edge 13 of the receiving base 10 and thus abuts against this. For receiving the locking bolt 30 in the pivoting position, the receiving base 10 has two recesses 19, in which the locking bolt 30, when they are pushed by the cutting set 3 in the direction of the pivot axis 18, can dip, so that a pivoting movement of the receiving leg 20 is released.

Die Schwenkachse 18 ist an der Aufnahmebasis 10 außenseitig über zwei Lagerbuchsen 16 gehalten, die im vorliegenden Ausführungsbeispiel einstückig an die Aufnahmebasis 10 angeformt sind.The pivot axis 18 is held on the receiving base 10 on the outside via two bearing bushes 16, which are integrally formed in the present embodiment of the receiving base 10.

Die Aufnahmebasis 10 weist außerdem zwei Befestigungsbohrungen 14 auf, durch die die Aufnahmebasis 10 mittels zweier Schrauben an der Haarschneidemaschine befestigbar ist.The receiving base 10 also has two mounting holes 14, through which the receiving base 10 can be fastened by means of two screws on the hair clipper.

Figur 5 zeigt ein zweites Ausführungsbeispiel einer erfindungsgemäßen Schneidsatzaufnahme 1. Die Schneidsatzaufnahme 1 gemäß Figur 5 unterscheidet sich von der Schneidsatzaufnahme 1 gemäß Figur 4 dadurch, dass das Sperrelement 30 nicht als Sperrriegel, sondern als sogenannter Sperrwinkel 30 ausgebildet ist. Ein entsprechender Sperrwinkel 30 weist eine Sperrnase 39 auf, die in Blockierstellung des Sperrwinkels an der Aufnahmebasis 10 anschlägt und damit eine Schwenkbewegung des Aufnahmeschenkels 20 in Richtung der Aufnahmebasis 10 blockiert. Ein derartiger Sperrwinkel 30 kann, wie in Figur 5 dargestellt, abhängig von seiner Lagerung, auf zweierlei Art und Weise von der Blockierstellung in die Schwenkstellung überführt werden. FIG. 5 shows a second embodiment of a cutting set according to the invention recording 1. The Schneidsatzaufnahme 1 according to FIG. 5 differs from the Schneidsatzaufnahme 1 according to FIG. 4 in that the blocking element 30 is not designed as a locking bolt, but as a so-called blocking angle 30. A corresponding locking angle 30 has a locking lug 39 which abuts in the blocking position of the blocking angle on the receiving base 10 and thus blocks a pivoting movement of the receiving leg 20 in the direction of the receiving base 10. Such a locking angle 30 can, as in FIG. 5 shown, depending on its storage, be transferred from the blocking position to the pivot position in two ways.

In einer ersten Variante ist der Sperrwinkel 30 an der Schwenkachse 18 gelagert und entlang der Achse 18 verschiebbar ausgebildet. Um eine Überführung des Sperrwinkels 30 von der Blockierstellung in die Schwenkstellung zu bewirken, ist eine Anlaufkante 37 vorgesehen, die derart ausgebildet ist, dass sie eine lineare Aufschiebbewegung des Schneidsatzes 3 in Richtung der Schwenkachse 18 in eine lineare Bewegung des Sperrwinkels 30 parallel zu der Schwenkachse 18 überführt. Die Sperrnase 39 wird auf diese Weise ebenfalls parallel zu der Schwenkachse 18 verschoben und kann damit von einer Positionierung über der Aufnahmebasis 10 in eine Position im Bereich einer der Ausnehmungen 19 überführt werden. Die Sperrnase 39 ist dann so angeordnet, dass sie in die Ausnehmungen 19 eintaucht und damit eine Schwenkbewegung des Aufnahmeschenkels 20 in Richtung der Aufnahmebasis 10 zulässt.In a first variant of the locking angle 30 is mounted on the pivot axis 18 and formed along the axis 18 slidably. In order to effect a transfer of the blocking angle 30 from the blocking position to the pivoting position, a starting edge 37 is provided, which is designed such that it causes a linear Aufschiebbewegung of the cutting set 3 in the direction of the pivot axis 18 in a linear movement of the blocking angle 30 parallel to the pivot axis 18 transferred. The locking lug 39 is thus also moved parallel to the pivot axis 18 and can thus be transferred from a positioning on the receiving base 10 in a position in the region of one of the recesses 19. The locking lug 39 is then arranged so that it dips into the recesses 19 and thus allows a pivoting movement of the receiving leg 20 in the direction of the receiving base 10.

Eine Federbelastung des Sperrwinkels 30 kann in dieser Ausgestaltungsform bspw. durch eine auf der Schwenkachse 18 angeordnete Schraubenfeder besonders einfach erreicht werden.A spring load of the blocking angle 30 can be achieved particularly easily in this embodiment, for example, by a coil spring arranged on the pivot axis 18.

In einer zweiten Ausgestaltungsform ist der Sperrwinkel 30 entweder an der Aufnahmebasis oder an dem Aufnahmeschenkel schwenkbar gelagert und wird durch eine Aufsteckbewegung des Schneidsatzes 3 in eine Position über der Ausnehmung 19 verschwenkt, sodass auch in dieser Position eine Schwenkbewegung zwischen Aufnahmeschenkel 20 und Aufnahmebasis 10 freigegeben ist.In a second embodiment, the locking angle 30 is pivotally mounted either on the receiving base or on the receiving leg and is pivoted by a Aufsteckbewegung of the cutting set 3 in a position above the recess 19, so that in this position, a pivotal movement between receiving leg 20 and receiving base 10 is released ,

Grundsätzlich besteht noch eine Reihe weiterer Möglichkeiten zur Ausgestaltung einer Schneidsatzaufnahme 1 mit einem Sperrelement 30, die ohne vom Grundgedanken der Erfindung abzuweichen realisiert werden können. Insbesondere ist eine Ausgestaltung von Aufnahmebasis 10, Aufnahmeschenkel 20 und Sperrelement möglich, bei der die Ausnehmung 19 nicht in der Aufnahmebasis 10, sondern an dem Aufnahmeschenkel 20 oder an dem Sperrelement 30 vorgesehen istIn principle, there are a number of other possibilities for designing a cutting set holder 1 with a blocking element 30, which can be realized without deviating from the basic idea of the invention. In particular, an embodiment of the receiving base 10, receiving leg 20 and blocking element is possible, in which the recess 19 is not provided in the receiving base 10, but on the receiving leg 20 or on the blocking element 30
