Description

Die Erfindung betrifft einen mehrteiligen SchlĂŒssel zur BetĂ€tigung eines Schlosses, bestehend aus einem Basisteil mit einem hinteren Halmabschnitt und der Reide und einem Funktionsteil mit einem vorderen Halmabschnitt und dem SchlĂŒsselbart. Die Erfindung betrifft außerdem ein Verfahren zur Herstellung eines mehrteiligen SchlĂŒssels zur BetĂ€tigung eines Schlosses, bestehend aus einem Basisteil mit einem hinteren Halmabschnitt und der Reide und einem Funktionsteil mit einem vorderen Halmabschnitt und dem SchlĂŒsselbart und einem fest mit dem Basisteil oder mit dem Funktionsteil verbundenen Adapter,The invention relates to a multi-part key for actuating a lock, consisting of a base part with a rear blade section and the Reide and a functional part with a front Halmabschnitt and the key bit. The invention also relates to a method for producing a multi-part key for actuating a lock, comprising a base part with a rear blade section and the Reide and a functional part with a front blade section and the key bit and an adapter fixedly connected to the base part or with the functional part,

SchlĂŒssel aus mehreren Komponenten sind bekannt, sie bestehen aus einem Basis- und einem Funktionsteil. Beide weisen einen Halmabschnitt auf und werden zumeist ĂŒber einen zur Übertragung der Drehmomente geeigneten Einhakmechanismus miteinander verbunden. Es handelt sich also bei dem Basisteil um eine standardisierte Komponente, die einer auf das jeweilige Schloss abgestimmten, individuellen Komponente, dem Funktionsteil verbunden und kombiniert wird. ZweckmĂ€ĂŸig ist ein solch mehrteiliger SchlĂŒssel etwa bei Nutzern, die eine Vielzahl von SchlĂŒsseln mit sich tragen mĂŒssen und die das standardisierte Basisteil dann jeweils mit dem Funktionsteil kombinieren, um Aufwand bezĂŒglich Platz und Gewicht zu sparen. Weil die Verbindung zwischen Basis- und Funktionsteil einerseits lösbar sein und andererseits aber auch die Übertragung von Drehmomenten gewĂ€hrleisten muss, ist der Mechanismus relativ kompliziert. So weist eines der Bauteile in der Regel zwei Stege auf, um die das andere Teil in einer Schwenkbewegung eingeklinkt wird. Dies bringt mit sich, dass der jeweilige SchlĂŒsselteil sehr kompliziert herzustellen ist. HierfĂŒr sind Prozesse wie das Herstellen der Schweißverbindung zwischen hinterem Halmabschnitt und Reide und darĂŒber hinaus FrĂ€sen, Senken, Schleifen, Vernieten etc. notwendig, was die Kosten fĂŒr die Herstellung eines solchen SchlĂŒssels natĂŒrlich maßgeblich in die Höhe treibt.Keys from several components are known, they consist of a base and a functional part. Both have a Halmabschnitt and are usually connected to each other via a suitable for transmitting the torque hooking mechanism. Thus, the base part is a standardized component which is connected and combined to an individual component, the functional part, which is matched to the respective lock. Suitably, such a multi-part key is about users who have to carry a variety of keys with them and then combine the standardized base part with each of the functional part to save effort in terms of space and weight. Because the connection between the base and functional part on the one hand be solvable and on the other hand, but must also ensure the transmission of torque, the mechanism is relatively complicated. Thus, one of the components usually has two webs around which the other part is latched in a pivoting movement. This implies that the respective key part is very complicated to manufacture. For this purpose, processes such as making the weld between the rear Halmabschnitt and Reide and beyond milling, countersinking, grinding, riveting, etc. necessary, what the Of course, the cost of producing such a key is significantly increasing.

Damit stellt sich der vorliegenden Erfindung die Aufgabe, einen mehrteiligen SchlĂŒssel zu schaffen, der weitgehend standardisiert und damit wesentlich kostengĂŒnstiger hergestellt werden kann.Thus, the present invention has the object to provide a multi-part key that can be largely standardized and thus manufactured much cheaper.

Diese Aufgabe wird vorrichtungsgemĂ€ĂŸ dadurch gelöst, dass zwischen Basisteil und Funktionsteil ein fest mit dem Basisteil oder mit dem Funktionsteil verbundener Adapter vorgesehen ist.This object is achieved according to the device in that between the base part and the functional part of an integral with the base part or with the functional part adapter is provided.

Durch die feste Verbindung von Basisteil und Adapter oder dem auf das Schließwerk abgestimmten Funktionsteil und Adapter bilden diese quasi eine funktionelle Einheit, die im Bedarfsfall mit dem jeweiligen anderen SchlĂŒsselteil, sei es Funktionsteil, sei es Basisteil, kombiniert, d.h. lösbar verbunden wird. Es wird dadurch ermöglicht, den relativ kompliziert bauenden Einhakmechanismus durch Zuordnung zu dem Adapter auf geeignete Weise separat und damit den SchlĂŒssel als Ganzes deutlich kostengĂŒnstiger herzustellen.Due to the firm connection of the base part and the adapter or the functional part and adapter matched to the locking mechanism, these form a functional unit which, if necessary, combines with the respective other key part, be it the functional part or the base part, i. is detachably connected. It is thereby made possible to produce the relatively complicated built hooking mechanism by assignment to the adapter in a suitable manner separately and thus the key as a whole much cheaper.

In diesem Sinne ist auch der Vorschlag zu verstehen, dass es sich bei dem Adapter um ein bezĂŒglich Abmessungen und Ausbildung standardisiertes Bauteil handelt. Damit umfasst der erfindungsgemĂ€ĂŸ aus drei Teilen bestehende SchlĂŒssel zwei standardisierte und damit vereinfacht und kostengĂŒnstig herstellbare Teile, nĂ€mlich Basisteil und Adapter. Dies gilt unabhĂ€ngig davon, ob der Adapter dem Basis- oder dem Funktionsteil zugeordnet ist.In this sense, the suggestion is to be understood that the adapter is a standardized component in terms of dimensions and design. Thus, the present invention consisting of three parts key comprises two standardized and therefore simplified and inexpensive to produce parts, namely base and adapter. This applies regardless of whether the adapter is assigned to the base or the functional part.

Eine bevorzugte Variante sieht dabei vor, dass der Adapter als Halmabschnitt ausgebildet ist. Dieser ist zwischen Funktions- und Basisteil positioniert und korrespondierend zu beiden ausgebildet. Der Adapter ist also praktisch eine VerlÀngerung des Basis- oder des Funktionsteils mit dem Einhakmechanismus am anderen Ende und kann in einem auf die Anforderungen gerade in Hinblick auf den Einhakmechanismus abgestimmten Verfahren hergestellt werden.A preferred variant provides that the adapter is designed as a Halmabschnitt. This is positioned between functional and base part and formed corresponding to both. The adapter is thus practically an extension of the base or the functional part with the Einhakmechanismus at the other end and can in one to the requirements be made just in terms of the hook mechanism coordinated procedures.

Fertigungstechnisch ist es vorteilhaft, wenn der Adapter und das Funktionsbauteil eine Baueinheit bilden. Dies ist auf vorteilhafte Weise z. B. der Fall, wenn der Funktionsteil als Zinkdruckgussteil direkt an den Adapter angegossen wird. Der vorgefertigte Adapter wird dabei in das Zinkdruckgusswerkzeug eingelegt, sodass eine Baueinheit, bestehend aus Funktionsbauteil und Adapter entsteht.Manufacturing technology, it is advantageous if the adapter and the functional component form a structural unit. This is advantageous manner z. As is the case when the functional part is cast as zinc die casting directly to the adapter. The prefabricated adapter is inserted into the zinc die casting tool, resulting in a structural unit consisting of functional component and adapter.

Besonders zweckmĂ€ĂŸig ist es außerdem, wenn der Adapter einteilig ausgebildet ist. Der entsprechend hergestellte Halmabschnitt umfasst dabei den Einhakmechanismus in Form einer Ausnehmung mit zwei innerhalb dieser quer angeordneten Stegen.It is also particularly useful if the adapter is integrally formed. The correspondingly produced blade section in this case comprises the hooking mechanism in the form of a recess with two webs arranged transversely within the latter.

In Hinblick auf die Verbindung zwischen Basisteil und Adapter bzw. Funktionsteil und Adapter ist daran gedacht, dass der Adapter, das Basisteil oder das Funktionsteil mit einem zapfenartigen Ende versehen ist. Das jeweils andere Bauteil weist eine korrespondierend zu dem zapfenartigen Ende ausgebildete Aufnahme fĂŒr dieses auf.With regard to the connection between the base part and the adapter or functional part and adapter is thought that the adapter, the base part or the functional part is provided with a pin-like end. The respective other component has a corresponding to the pin-like end formed receptacle for this.

Um eine möglichst hohen Beanspruchungen standhaltende Verbindung zum Adapter zu erreichen, ist daran gedacht, dass der Adapter ĂŒber eine Press- oder Schrumpfverbindung mit dem Basisteil oder dem Funktionsteil verbunden ist. Eine Alternative dazu sieht vor, dass der Adapter ĂŒber ein Gewinde mit dem Basisteil oder dem Funktionsteil verbunden ist.In order to achieve the highest possible stress-resistant connection to the adapter, it is envisaged that the adapter is connected via a press or shrink connection with the base part or the functional part. An alternative to this provides that the adapter is connected via a thread to the base part or the functional part.

Eine AusfĂŒhrungsform sieht vor, dass das zapfenartige Ende mit einem Gewinde oder einem RĂ€ndel versehen ist. Das zapfenartige Ende, das Bestandteil des Basisteils, des Funktionsteils oder des Adapters sein kann, trĂ€gt also ein Gewinde oder ein RĂ€ndel zur Herstellung der Verbindung mit dem restlichen SchlĂŒssel.An embodiment provides that the pin-like end is provided with a thread or a knurl. The pin-like end, which may be part of the base part, the functional part or the adapter, thus contributes Thread or a knurl to connect to the rest of the key.

Eine Alternative zu Gewinde oder RĂ€ndel sieht vor, dass das zapfenartige Ende als DĂŒbel ausgebildet ist. Damit ist eine Sicherung gegen das Abziehen des Adapters aus dem diesem zugeordneten Basis- oder Funktionsteil realisiert. Hierzu weist der DĂŒbel eine Vielzahl von Verzahnungen auf, die eine solche Trennung verhindern sollen.An alternative to thread or knurls provides that the pin-like end is designed as a dowel. For a backup against the removal of the adapter from the associated base or functional part is realized. For this purpose, the dowel on a variety of teeth, which should prevent such a separation.

Um die Trennung des DĂŒbels von dem ihm zugeordneten Bauteil nicht nur in Richtung LĂ€ngsachse des SchlĂŒssels, sondern auch bei Drehung um diese zu verhindern, ist vorgesehen, dass der DĂŒbel mit einer Verdrehsicherung ausgerĂŒstet ist.In order to prevent the separation of the dowel from its associated component not only in the direction of the longitudinal axis of the key, but also during rotation about this, it is provided that the dowel is equipped with a rotation.

Eine solche Verdrehsicherung kann in der Form ausgebildet sein, dass der DĂŒbel mindestens eine LĂ€ngsnut aufweist, die sich parallel zur LĂ€ngsachse des SchlĂŒssels bzw. des Adapters erstreckt. Bevorzugt sind zwei um 180° versetzt angeordnete LĂ€ngsnuten, die eine Verdrehung der SchlĂŒsselteile verhindern.Such an anti-rotation device can be designed in the form that the plug has at least one longitudinal groove which extends parallel to the longitudinal axis of the key or of the adapter. Preferably, two offset by 180 ° longitudinal grooves which prevent rotation of the key parts.

Zur Herstellung der eigentlichen Verbindung oder aber zur zusĂ€tzlichen Sicherung einer der zuvor beschriebenen mechanischen Verbindungen ist daran gedacht, dass der Adapter ĂŒber Klebung mit dem Basisteil oder dem Funktionsteil verbunden ist.For the production of the actual connection or for the additional securing of one of the mechanical connections described above, it is envisaged that the adapter is connected by gluing to the base part or the functional part.

Um eine besonders gut lösbare Verbindung des Adapters zu erreichen, ist vorgesehen, dass der Adapter mit dem Funktionsteil oder dem Basisteil ĂŒber einen Einhakmechanismus verbunden ist, wobei der Adapter zwei Stege aufweist, zu denen das Funktionsteil oder das Basisteil korrespondierend ausgebildet ist. Die umgekehrte AusfĂŒhrung, bei der das Funktions- oder das Basisteil zwei Stege aufweist, zu denen der Adapter korrespondierend ausgebildet ist, ist ebenso denkbar.In order to achieve a particularly easily releasable connection of the adapter, it is provided that the adapter is connected to the functional part or the base part via a hooking mechanism, wherein the adapter has two webs to which the functional part or the base part is formed corresponding. The reverse embodiment, in which the functional or the base part has two webs, to which the adapter is formed corresponding, is also conceivable.

Es wurde bereits erwĂ€hnt, dass es sich bei dem Adapter um ein standardisiertes Bauteil handelt, dass also letztlich ein solcher Adapter mit Basis- und Funktionsteilen unterschiedlichster Art, Ausbildung und LĂ€nge kombiniert werden kann. Um hier einerseits zu erreichen, dass der Adapter sowohl mit Basisals auch Funktionsteil gut verbunden werden kann und andererseits zu ermöglichen, dass die hohen KrĂ€fte und Momente hier gut ĂŒbertragen werden können, ist daran gedacht, dass der Adapter eine LĂ€nge von 20 mm bis 40 mm , vorzugsweise 30 mm, aufweist. Variationen in der LĂ€nge des SchlĂŒssels als Gesamtbauteil in Hinblick auf die jeweiligen Anforderungen im Zusammenhang mit dem Schloss können dann ĂŒber den Basisteil erreicht werden.It has already been mentioned that the adapter is a standardized component, so that in the end such an adapter can be combined with basic and functional parts of the most varied type, design and length. To achieve here on the one hand, that the adapter can be well connected with both Basisals and functional part and on the other hand to allow the high forces and moments can be transferred well here, it is thought that the adapter has a length of 20 mm to 40 mm , preferably 30 mm. Variations in the length of the key as a total component with respect to the respective requirements associated with the lock can then be achieved via the base part.

Ein Kernpunkt der Erfindung liegt darin, das Basisteil nunmehr deutlich vergĂŒnstigt herstellen zu können, indem nicht mehr eine Bearbeitung des Basis- oder Funktionsteils zur Herstellung des Einhakmechanismus notwendig ist. Vielmehr wird hierzu ein standardisiertes Bauteil in Form des Adapters vorgeschlagen. Es empfiehlt sich daher, den Adapter getrennt herzustellen. ZweckmĂ€ĂŸigerweise geschieht dies in einem Verfahren, mit dem der Einhakmechanismus quasi in nur einem Arbeitsgang mit der Herstellung des eigentlichen Adapters bewerkstelligt werden kann. Im Hinblick auf das Material ist hierbei vorgesehen, dass der Adapter aus Metall oder Kunststoff hergestellt ist.A key point of the invention is to be able to produce the base part now significantly cheaper by no longer a processing of the base or functional part for the preparation of the hooking mechanism is necessary. Rather, a standardized component in the form of the adapter is proposed for this purpose. It is therefore recommended to make the adapter separately. Appropriately, this is done in a method with which the hooking mechanism can be accomplished quasi in only one operation with the production of the actual adapter. With regard to the material here is provided that the adapter is made of metal or plastic.

Z. B. ist es vorteilhaft, wenn der Adapter im Metallpulverspritzgussverfahren hergestellt ist. Der Adapter wird dabei pulvermetallurgisch hergestellt, was praktisch kaum Nachbearbeitungsbedarf erfordert. Hiermit kann auch der in Hinblick auf den Einhakmechanismus geometrisch komplexe Adapter quasi in einem Schritt hergestellt werden. Im Rahmen dieses Verfahrens werden die Metallpulver mechanisch in Formwerkzeugen verdichtet und anschließend bei hohen Temperaturen zu Fertigteilen gesintert. Dieses auch als Metal Injection Moulding bezeichnete Verfahren hat sich auch in Zusammenhang mit den vorliegenden Adaptern als besonders geeignet erwiesen.For example, it is advantageous if the adapter is produced in the metal powder injection molding process. The adapter is made by powder metallurgy, which requires virtually no Nachbearbeitungsbedarf. Hereby, the geometrically complex adapter with regard to the hooking mechanism can also be produced in one step, as it were. As part of this process, the metal powders are mechanically compacted in molds and then sintered at high temperatures to finished parts. This process, which is also referred to as metal injection molding, has proven to be particularly suitable in connection with the present adapters.

Die erfindungsgemĂ€ĂŸe Aufgabe wird verfahrensgemĂ€ĂŸ dadurch gelöst, dass zunĂ€chst der Adapter im Metallpulverspritzgussverfahren hergestellt wird und dass der Adapter anschließend in ein Zinkdruckgusswerkzeug eingelegt und das Funktionsteil als Zinkdruckgussteil an den Adapter angegossen wird.The object of the invention is achieved according to the method in that first the adapter is produced in the metal powder injection molding process and that the adapter is then placed in a zinc die casting tool and the functional part is cast as a zinc diecasting to the adapter.

Das Verfahren zur Herstellung dieses SchlĂŒsselteils umfasst also zwei Schritte. ZunĂ€chst wird im Metallpulverspritzgussverfahren der Adapter als geometrisch besonders komplexes Bauteil hergestellt. Der Adapter wird dann in ein Zinkdruckgusswerkzeug eingelegt, woraufhin das Funktionsteil als Zinkdruckgussteil direkt an den Adapter angegossen wird.The method of making this key part thus involves two steps. First, in the metal powder injection molding process, the adapter is manufactured as a geometrically particularly complex component. The adapter is then placed in a zinc die-casting tool, whereupon the functional part is cast as a zinc die-cast part directly to the adapter.

Die Erfindung zeichnet sich insbesondere dadurch aus, dass ein mehrteiliger SchlĂŒssel geschaffen ist, der ĂŒber ein Basisteil, bestehend aus hinterem Halmabschnitt und Reide, und ein Funktionsteil, bestehend aus vorderem Halmabschnitt und SchlĂŒsselbart hinaus einen dazwischen angeordneten Adapter aufweist, bei dem es sich vorteilhafterweise um ein Standardbauteil handeln kann. Den kompliziert bauenden Teil des Einhakmechanismus, ĂŒber den die Verbindung zu dem jeweiligen restlichen SchlĂŒssel hergestellt wird, nĂ€mlich zwei in einer Ausnehmung angeordnete Stege, weist nunmehr der Adapter auf. Dieser wird dabei in einem Verfahren hergestellt, das fĂŒr ein geometrisch derart aufwendig bauendes Bauteil besonders geeignet ist, zweckmĂ€ĂŸigerweise im Metallpulverspritzguss. Hierdurch können gleich mehrere ArbeitsgĂ€nge eingespart werden, die zuvor notwendig waren, um das im Gießverfahren hergestellte Basisteil fĂŒr den Einhakmechanismus nachzubearbeiten. Die Adapter werden dann fest mit dem Basis- oder Funktionsteil durch Pressen, Schrumpfen, Verschrauben, RĂ€ndeln, DĂŒbeln, Eingießen und/oder Kleben verbunden, so dass Adapter und Basis- oder Funktionsteil eine Einheit bilden.The invention is characterized in particular by the fact that a multi-part key is provided, which has a base member consisting of rear Halmabschnitt and Reide, and a functional part consisting of front Halmabschnitt and key bit beyond an adapter arranged therebetween, in which advantageously a standard component can act. The complicated building part of the hooking mechanism, via which the connection is made to the respective remaining key, namely two webs arranged in a recess, now has the adapter. This is produced in a process which is particularly suitable for a geometrically complex component, expediently in the metal powder injection molding. As a result, several operations can be saved, which were previously necessary to post-process the base part produced by the casting process for the hooking. The adapters are then fixedly connected to the base or functional part by pressing, shrinking, screwing, knurling, dowelling, pouring and / or gluing, so that adapter and base or functional part form a unit.

Figur 1 zeigt den mehrteiligen SchlĂŒssel in Explosionsdarstellung. Dieser weist zunĂ€chst den Basisteil 2 und den Adapter 4 auf, die hier zur besseren Veranschaulichung nicht verbunden dargestellt sind, aber eine funktionelle Einheit durch eine feste Verbindung aufweisen. Ersterer weist einen vergleichsweise langen, hinteren Halmabschnitt 5 und die Reide 8 sowie ein zapfenartig ausgebildetes Ende 11 auf. Zweiterer ist durch den mittleren Halmabschnitt 7 gebildet. Der SchlĂŒssel 1 wird dann eigentlich erst zu einem solchen, wenn ĂŒber den Einhakmechanismus 14 eine lösbare Verbindung zwischen der aus Basisteil 2 und Adapter 4 gebildeten Baueinheit und dem Funktionsteil 3 hergestellt wird. Dieses wiederum weist neben dem vorderen Halmabschnitt 6 den SchlĂŒsselbart 9 zur BetĂ€tigung des hier nicht dargestellten Schlosses auf. Der Funktionsteil 3 hat an seinem dem Adapter 4 zugewandten Ende 18 zwei einander gegenĂŒber liegend angeordnete Kerben 19 und 20, welche korrespondierend zu den hier nicht erkennbaren Stegen im Adapter 4 ausgebildet sind.Figure 1 shows the multipart key in an exploded view. This first comprises the base part 2 and the adapter 4, which are not shown here connected for better illustration, but have a functional unit by a fixed connection. The former has a comparatively long, rear blade section 5 and the Reide 8 and a pin-like end 11 formed. The second is formed by the central blade section 7. The key 1 then actually becomes such only when a releasable connection between the assembly formed from base part 2 and adapter 4 and the functional part 3 is produced via the hooking mechanism 14. This in turn, in addition to the front blade section 6 on the key bit 9 for actuating the lock, not shown here. The functional part 3 has at its end facing the adapter 4 two oppositely disposed notches 19 and 20 which are formed corresponding to the webs not recognizable in the adapter 4.

WĂ€hrend in der Darstellung gemĂ€ĂŸ Figur 1 das zapfenartige Ende dem Basisteil 2 zugeordnet ist, ist es in der Darstellung gemĂ€ĂŸ Figur 2 Bestandteil des Adapters 4, womit veranschaulicht werden soll, dass hier mehrere Varianten denkbar sind. Das Basisteil 2 mit den Halmabschnitten 5 und 5' besteht hier aus zwei Teilen 2 und 2' mit dem Abstand 17, was sich aber nur auf die Darstellung bezieht. Hiermit soll zusĂ€tzlich veranschaulicht werden, dass einerseits das Bauteil Adapter 4 eine standardisierte LĂ€nge aufweist, wĂ€hrend andererseits das Basisteil 2 zur Anpassung an das Schloss unterschiedliche LĂ€ngen aufweisen kann.While the pin-like end is assigned to the base part 2 in the representation according to FIG. 1, it is part of the adapter 4 in the representation according to FIG. 2, which is intended to illustrate that several variants are conceivable here. The base part 2 with the Halmabschnitten 5 and 5 'is made here two parts 2 and 2 'with the distance 17, which refers only to the representation. This is additionally intended to illustrate that, on the one hand, the component adapter 4 has a standardized length, while on the other hand, the base part 2 may have different lengths for adaptation to the lock.

Figur 3 zeigt einen Adapter mit der lÀnglichen Ausnehmung 21 am dem Funktionsteil zugewandten Ende 22 und den beiden Stegen 15 und 16, die miteinander den Einhakmechanismus 14 bilden. Am dem dem Basisteil zugewandten zapfenartigen Ende 11 weist der Adapter 4 hier ein RÀndel auf.Figure 3 shows an adapter with the elongated recess 21 on the functional part facing the end 22 and the two webs 15 and 16, which together form the Einhakmechanismus 14. At the base part facing the pin-like end 11, the adapter 4 has a knurl here.

Eine Variante hierzu zeigt Figur 4, nĂ€mlich eine Aufnahme 23 fĂŒr das zapfenartige Ende, das in diesem Fall dem Basisteil zugeordnet ist.A variant of this is shown in Figure 4, namely a receptacle 23 for the pin-like end, which is assigned to the base part in this case.

Den Adapter 4 in einer solchen Form zeigt auch Figur 5 mit den beiden Stegen 15 und 16 und dem Gewinde 12 in der Aufnahme 23.The adapter 4 in such a form is also shown in FIG. 5 with the two webs 15 and 16 and the thread 12 in the receptacle 23.

Um 90° gedreht ist dieser Adapter in Figur 6 dargestellt, wo sich zeigt, dass die Stege 15 und 16 versetzt zueinander angeordnet sind, um hier den Einhakmechanismus mit dem Ende des Funktionsteils gewÀhrleisten zu können.Turned by 90 °, this adapter is shown in Figure 6, where it is shown that the webs 15 and 16 are arranged offset from one another, to ensure here the Einhakmechanismus with the end of the functional part can.

In Figur 7 ist ein mehrteiliger SchlĂŒssel 1 gezeigt, bei dem Funktionsteil 3 und Adapter 4 eine funktionelle Einheit 10 durch eine feste Verbindung bilden. Der Basisteil besteht aus den beiden Teilen 2 und 2', die zusammen den Halmabschnitt 5 bilden. Am Ende 34 des Basisteils 2 befindet sich eine HĂ€lfte des Einhakmechanismus 14', die andere HĂ€lfte 14 ist Bestandteil der aus Funktionsteil 3 und Adapter 4 gebildeten Einheit 10. Zu deren Herstellung wird zunĂ€chst der Adapter 4, vorzugsweise im Metallpulverspritzgussverfahren hergestellt, anschließend wird der Adapter 4 in ein Zinkdruckgusswerkzeug eingelegt, woraufhin der Funktionsteil 3 mit Halmabschnitt 7 und SchlĂŒsselbart 9 an den Adapter 4 angegossen wird.FIG. 7 shows a multi-part key 1, in which functional part 3 and adapter 4 form a functional unit 10 by means of a fixed connection. The base part consists of the two parts 2 and 2 ', which together form the blade section 5. At the end 34 of the base part 2 is one half of the hooking mechanism 14 ', the other half 14 is part of the functional part 3 and adapter 4 formed unit 10. For their preparation, the adapter 4, preferably produced in the metal powder injection molding process, then the adapter 4 inserted into a zinc die-casting, whereupon the functional part 3 is molded with Halmabschnitt 7 and key bit 9 to the adapter 4.

Figur 8 zeigt einen Adapter 4 mit dem Einhakmechanismus 14 und einem zapfenartigen Ende 11 in Form eines DĂŒbels 26. Dieser weist als Zugsicherung in LĂ€ngsachsenrichtung 33 des Adapters 4 wie des SchlĂŒssels mehrere Verzahnungen 30, 31, 32 auf. Als Verdrehsicherung 24 dienen die parallel zur LĂ€ngsachse 33 angeordneten und um 180° versetzten LĂ€ngsnuten 28 und 29.Figure 8 shows an adapter 4 with the hooking mechanism 14 and a pin-like end 11 in the form of a dowel 26. This has several teeth 30, 31, 32 as Zugsicherung in the longitudinal axis direction 33 of the adapter 4 as the key. Serve as anti-rotation 24 parallel to the longitudinal axis 33 and offset by 180 ° longitudinal grooves 28 and 29th
