Description

Die Erfindung betrifft eine Anordnung von Bauteilen, die relativ zueinander beweglich sind und in mindestens zwei Positionen mittels einer Rastvorrichtung eine definierte stabile Lage einnehmen, der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to an arrangement of components which are movable relative to each other and occupy a defined stable position in at least two positions by means of a latching device, the genus specified in the preamble of claim 1.

Bei Verstellmechanismen werden im allgemeinen mindestens zwei Bauteile relativ zu einander bewegt, wobei es häufig erforderlich ist, in vorgegebenen Positionen eine stabile Lage zu schaffen. Aus dieser Lage heraus ist dann durch Überwindung der Haltekraft eine relative Bewegung der Bauteile und Einnahme einer anderen Position möglich. Zur Festlegung in einer definierten stabilen Lage dienen häufig Rastvorrichtungen, d.h. eines der Bauteile weist eine Rastvertiefung und das andere Bauteil eine Rastnase auf.In adjustment mechanisms, at least two components are generally moved relative to each other, often requiring a stable position in predetermined positions. From this position, a relative movement of the components and taking another position is then possible by overcoming the holding force. For fixing in a defined stable position are often locking devices, i. one of the components has a latching depression and the other component has a latching nose.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung von Bauteilen der im Oberbegriff des Anspruchs 1 angegebenen Gattung zu schaffen, durch die die Handhabung zur Bewegung der Bauteile verbessert ist.The present invention has for its object to provide an arrangement of components of the type specified in the preamble of claim 1, through which the handling is improved to move the components.

Das Dokument US 6612628 B offenbart eine Anordnung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The document US 6,612,628 B discloses an arrangement having the features of the preamble of claim 1.

Diese Aufgabe wird durch eine Anordnung von Bauteilen mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an arrangement of components having the features of claim 1.

Durch die erfindungsgemäße Anordnung sind die erforderlichen Kräfte zur Verstellung der Bauteile zueinander in Abhängigkeit von der Betätigungsrichtung unterschiedlich, d.h. zum Entrasten müssen unterschiedlich große Haltekräfte überwunden werden.Due to the arrangement according to the invention, the forces required to move the components relative to one another are different depending on the direction of actuation, i. To unlock different levels of holding forces must be overcome.

Die Ausgestaltung der erfindungsgemäßen Anordnung wird darin gesehen, daß das erste und zweite Bauteil ein Drehgelenk bilden, wobei in einem ersten Gelenkteil eine kreisförmige Ausnehmung vorgesehen ist, in der ein mit einem zweiten Gelenkteil drehbarer Körper aufgenommen ist und an der Umfangswandung der Ausnehmung und dem Außenumfang des Körpers die Rastvorrichtung angeordnet ist. Ein derartiges Drehgelenk ist vielfältig einsetzbar, wobei durch den Winkelabstand der Rastvertiefungen auch der Drehwinkel der definierten stabilen Lage vorgegeben werden kann. Dabei ist es auch möglich, mehrere Rastvertiefungen in unterschiedlichen Abständen anzuordnen. Durch die kreisförmige Ausnehmung mit einem darin befindlichen drehbaren Körper und der Anordnung der Rastvorrichtung im Umfangsbereich zwischen diesen Teilen führt zu einer kompakten Bauweise.The embodiment of the arrangement according to the invention is seen in that the first and second components form a hinge, wherein in a first hinge part, a circular recess is provided, in which a rotatable with a second joint part body is received and on the peripheral wall of the recess and the outer periphery the body is arranged the locking device. Such a hinge can be used in many ways, wherein the angle of rotation of the locking recesses and the rotation angle of the defined stable position can be specified. It is also possible to arrange a plurality of locking recesses in different distances. Due to the circular recess with a rotatable body therein and the arrangement of the locking device in the peripheral region between these parts leads to a compact design.

Gemäß einer bevorzugten Weiterbildung der Erfindung werden diese unterschiedlich großen Haltekräfte dadurch erreicht, daß die Rastnase und/oder Rastvertiefung eine unsymmetrische Querschnittsform aufweisen. Damit können flachere oder steilere Konturen in der einen oder anderen Richtung gegeben sein, die neben der grundsätzlichen Form der Rastnase bzw. Rastvertiefung wesentlichen Einfluß auf die Haltekräfte nehmen. Außerdem ist es zweckmäßig, daß die Rastnase in Einrastrichtung von einer Feder belastet ist. Die Federkraft ist dabei mitbestimmend für die Haltekraft der Rastvorrichtung, wobei die Feder beispielsweise als ein elastischer Arm ausgebildet sein kann, an dem die Rastnase angeformt ist, oder die Feder auch ein zusätzliches auf die Rastnase wirkendes Bauteil sein kann.According to a preferred embodiment of the invention, these different-sized holding forces are achieved in that the latching lug and / or latching recess have an asymmetrical cross-sectional shape. This can be given flatter or steeper contours in one or the other direction, which take in addition to the basic shape of the latching lug or latching recess essential influence on the holding forces. In addition, it is expedient that the locking lug is loaded in the latching direction of a spring. The spring force is co-determining the holding force of the locking device, wherein the spring may be formed, for example, as an elastic arm on which the locking lug is formed, or the spring may also be an additional component acting on the latching lug.

Die Form der Rastnase und/oder Rastvertiefung kann entsprechend den gewünschten Bedingungen gestaltet werden, wobei - wie bereits erwähnt - unsymmetrische oder symmetrische Formen gewählt werden können. Beispielsweise können die Rastnase und/oder Rastvertiefung eine bogenförmig gewölbte Querschnittsform aufweisen oder aber in einer dreieckigen Querschnittsform gestaltet sein. Als besonders vorteilhaft werden daneben auch trapezförmige Querschnittsformen angesehen, wobei ein unregelmäßiges Trapez von besonderer Bedeutung ist, also mit verschieden steilen Schrägflächen oder unterschiedlich langen Flächen, und auf diese Weise für die unterschiedlichen Haltekräfte neben anderen Einflüssen mitbestimmend ist.The shape of the detent and / or detent recess can be designed according to the desired conditions, which - as already mentioned - unsymmetrical or symmetrical shapes can be selected. For example, the latching lug and / or latching recess may have an arcuately curved cross-sectional shape or else in a triangular cross-sectional shape be designed. In addition, trapezoidal cross-sectional shapes are considered to be particularly advantageous, with an irregular trapezium being of particular importance, that is to say with differently steep oblique surfaces or surfaces of different lengths, and in this way contributing, among other influences, to the different holding forces.

Zur weiteren Verbesserung der Funktion ist es zweckmäßig, daß die Rastvorrichtung drei Rastvertiefungen und drei Rastnasen umfaßt, die jeweils um einen Drehwinkel von 120° versetzt zueinander angeordnet sind. Dadurch erfolgt das Einrasten der drei Rastnasen gleichzeitig bei einer bestimmten Position und die jeweilige Haltekraft wird durch die drei Rastnasen gemeinsam erzeugt. Alternativ hierzu kann auch eine Anordnung der Rastungen derart gestaltet sein, daß diese bezogen auf die kreisförmige Bewegungsbahn um 180° zueinander versetzt sind. In weiterer Ausgestaltung ist vorgesehen, daß die Rastnasen an federnden Armen an dem Außenumfang des drehbaren Körpers angeformt sind, wobei diese Arme radial nach außen federn und somit die Rastnasen in die Rastvertiefungen bewegen. Zweckmäßigerweise ist der drehbare Körper als separates Bauteil ausgeführt und mit dem zweiten Gelenkteil drehfest verbunden. Auf diese Weise können der drehbare Körper und das zweite Gelenkteil aus unterschiedlichen Materialien hergestellt sein.To further improve the function, it is expedient that the locking device comprises three locking recesses and three locking lugs, which are each offset by an angle of rotation of 120 ° to each other. As a result, the engagement of the three latching lugs takes place simultaneously at a certain position and the respective holding force is generated jointly by the three latching lugs. Alternatively, an arrangement of the Notches be designed so that they are offset relative to the circular path of movement by 180 ° to each other. In a further embodiment it is provided that the latching lugs are formed on resilient arms on the outer periphery of the rotatable body, said arms spring radially outward and thus move the latching lugs in the latching recesses. Conveniently, the rotatable body is designed as a separate component and rotatably connected to the second joint part. In this way, the rotatable body and the second hinge part can be made of different materials.

Gemäß einer ersten Ausführungsform kann der drehbare Körper als Ring ausgebildet sein, wobei die drehfeste Verbindung eine Innenverzahnung am Ring und einen Zahnkranz am zweiten Gelenkteil umfaßt. Alternativ hierzu ist es auch möglich, den drehbaren Körper als runde Scheibe auszubilden und formschlüssig mit dem zweiten Gelenkteil zu verbinden. Hierzu sind beispielsweise in der Scheibe Öffnungen vorgesehen, in die entsprechende in axialer Richtung verlaufende Vorsprünge des zweiten Gelenkteils eingreifen.According to a first embodiment, the rotatable body may be formed as a ring, wherein the rotationally fixed connection comprises an internal toothing on the ring and a sprocket on the second joint part. Alternatively, it is also possible to form the rotatable body as a round disc and to connect positively to the second hinge part. For this purpose, openings are provided, for example, in the disc, engage in the corresponding extending in the axial direction of the second hinge part projections.

Eine einfach ausgestaltete Verbindung des ersten und zweiten Gelenkteils besteht darin, daß am Boden der kreisförmigen Ausnehmung ein zentrischer Zapfen oder eine Hülse vorgesehen ist, und der Zahnkranz des zweiten Gelenkteils eine zentrische Bohrung aufweist mittels der das zweite Gelenkteil auf dem Zapfen oder der Hülse gelagert ist. Zur einfachen Verbindung des Drehgelenks mit weiteren Bauteilen ist es zweckmäßig, daß das erste und zweite Gelenkteil mit Stutzen zum Einstecken in Anschlußbauteile versehen sind.A simply configured connection of the first and second hinge part is that at the bottom of the circular recess a central pin or sleeve is provided, and the ring gear of the second joint part has a central bore by means of which the second hinge part is mounted on the pin or the sleeve , For easy connection of the rotary joint with other components, it is expedient that the first and second hinge part are provided with connection for insertion into connecting components.

Die erfindungsgemäße Anordnung von Bauteilen mit Rastvorrichtungen kann selbstverständlich auch an anders verlaufenden Flächen der gegeneinander gleitenden Bauteile vorgesehen werden, wie beispielsweise ebenen Flächen.The arrangement of components according to the invention with latching devices can, of course, also be provided on differently extending surfaces of the components sliding against each other, such as, for example, flat surfaces.

In Fig. 1 ist ein Drehgelenk dargestellt, daß mit der erfindungsgemäßen Rastvorrichtung versehen ist. In einem ersten Bauteil 1 ist eine kreisförmige Ausnehmung 3 ausgebildet, die eine im wesentlichen zylindrische Wandung 17 und einen Boden 18 aufweist. Ein zweites Bauteil 2 ist mit einem Zahnkranz 14 und einem vorstehenden Zapfen 15 versehen, die in die Ausnehmung 3 eingesteckt werden, wobei das zweite Bauteil 2 derart gestaltet ist, daß es die Ausnehmung 3 im wesentlichen verschließt. Zwischen dem Zahnkranz 14 und der Wandung 17 der Ausnehmung 3 ist ein drehbarer Körper 4 vorgesehen, der drehfest auf dem Zahnkranz 14 befestigt ist. Das erste Bauteil 1 bildet somit ein erstes Gelenkteil 5 und das zweite Bauteil 2 bildet ein zweites Gelenkteil 6. Die Drehachse des aus den Gelenkteilen 5 und 6 gebildeten Drehgelenks ist mit dem Bezugszeichen D bezeichnet.In Fig. 1 is a rotary joint shown that is provided with the locking device according to the invention. In a first component 1, a circular recess 3 is formed, which has a substantially cylindrical wall 17 and a bottom 18. A second component 2 is provided with a sprocket 14 and a protruding pin 15 which are inserted into the recess 3, wherein the second component 2 is designed such that it substantially closes the recess 3. Between the sprocket 14 and the wall 17 of the recess 3, a rotatable body 4 is provided which is rotatably mounted on the sprocket 14. The first component 1 thus forms a first joint part 5 and the second component 2 forms a second joint part 6. The axis of rotation of the swivel joint formed from the joint parts 5 and 6 is denoted by the reference symbol D.

Der drehbare Körper 4 ist im Ausführungsbeispiel der Fig. 1 als Ring 11 mit einer Innenverzahnung 13 ausgeführt, wobei die Innenverzahnung 13 zum formschlüssigen Eingriff mit dem Zahnkranz 14 vorgesehen ist. Am Außenumfang des Ringes 11 sind drei federnde Arme 10 in gleichmäßigen Abständen und in der gleichen Richtung verlaufend angeformt, wobei an dem jeweils freien Ende der federnden Arme 10 eine Rastnase 9 ausgebildet ist. Die Rastnasen 9 werden während der Drehbewegung entlang der Wandung 17 der Ausnehmung 3 geführt und bei Erreichen einer der Rastvertiefungen 8 erfolgt ein selbsttätiges Einrasten der Rastnasen 9 in die Rastvertiefungen. An dem ersten Gelenkteil 5 ist ein Sockel 25 angeformt, an dem eine Anschlagfläche 21 ausgebildet ist. Spiegelbildlich zu dieser Anordnung ist an dem zweiten Gelenkteil 6 ein Sockel 26 angeformt, der eine Anschlagfläche 22 aufweist. An dem Sockel 25 und dem Sockel 26 ist jeweils ein Stutzen 7 vorgesehen, der zum Einstecken in Anschlußteile dient. In der Endposition, in welcher die beiden Stutzen 7 in dieselbe Richtung weisen, liegen die Anschlagflächen 21 und 22 aneinander.The rotatable body 4 is in the embodiment of Fig. 1 designed as a ring 11 with an internal toothing 13, wherein the internal toothing 13 is provided for positive engagement with the ring gear 14. On the outer circumference of the ring 11, three resilient arms 10 are formed at uniform intervals and extending in the same direction, wherein at the respective free end of the resilient arms 10 a detent 9 is formed. The locking lugs 9 are guided during the rotational movement along the wall 17 of the recess 3 and upon reaching one of the locking recesses 8 takes place an automatic engagement of the locking lugs 9 in the locking recesses. At the first hinge part 5, a base 25 is formed on which a stop surface 21 is formed. Mirrored to this arrangement, a base 26 is integrally formed on the second hinge part 6, which has a stop surface 22. At the base 25 and the base 26, a connecting piece 7 is provided in each case, which serves for insertion into connecting parts. In the end position, in which the two sockets 7 point in the same direction, the stop surfaces 21 and 22 abut each other.

Die Fig. 2 zeigt eine Ansicht des ersten Gelenkteils 5 mit der Ausnehmung 3 sowie dem angeformten Sockel 25 und dem Stutzen 7. Die Ausnehmung 3 besitzt einen kreisförmigen Querschnitt, wobei an der Wandung 17 mehrere Rastvertiefungen 8 bzw. 28 vorgesehen sind. Jeweils eine Rastvertiefung 8 und eine Rastvertiefung 28 bilden eine Gruppe von benachbarten Rastvertiefungen, wobei in dem in Fig. 2 gezeigten Ausführungsbeispiel die Rastnasen des drehbaren Körpers (vgl. Fig. 1) in der einen Endlage des Drehgelenkes in den Rastvertiefungen 8 befindlich sind und aus diesen heraus entgegen dem Uhrzeigersinn entlang der Wandung 17 bewegt werden bis sie in die Rastvertiefungen 28 einrasten. Damit ist dann die Endlage erreicht, bei der die Stutzen 7 beider Gelenkteile 5 und 6 des Drehgelenks in die selbe Richtung weisen. Am Boden 18 der Ausnehmung 3 ist eine zentrische Öffnung 16 vorgesehen, in die der in Fig. 1 angegebene Zapfen 15 des zweiten Gelenkteils 6 ragt und die Öffnung 16 sowie der Zapfen 15 ein Gleitlager bilden.The Fig. 2 shows a view of the first joint part 5 with the recess 3 and the molded base 25 and the nozzle 7. The recess 3 has a circular cross section, wherein on the wall 17 a plurality of locking recesses 8 and 28 are provided. In each case a latching recess 8 and a latching recess 28 form a group of adjacent latching depressions, wherein in the in Fig. 2 shown embodiment, the locking lugs of the rotatable body (see. Fig. 1 ) are located in the one end position of the rotary joint in the locking recesses 8 and are moved out of these counterclockwise along the wall 17 until they engage in the locking recesses 28. Thus, then the end position is reached, in which the sockets 7 of both joint parts 5 and 6 of the rotary joint point in the same direction. At the bottom 18 of the recess 3, a central opening 16 is provided in which the in Fig. 1 indicated pin 15 of the second joint part. 6 protrudes and the opening 16 and the pin 15 form a sliding bearing.

In den Fig. 3A und 3B ist die Einzelheit III in Fig. 2 in zwei unterschiedlichen Varianten dargestellt. Dabei ist die Rastvertiefung 28' der Fig. 3A wesentlich geringer als die Rastvertiefung 28 " in Fig. 3B, deren Querschnittsform nahezu einem Halbkreis entspricht. Die unterschiedlichen Formen machen deutlich, daß die Haltekräfte, die zum Entriegeln der Rastverbindung erforderlich sind in der Ausführung gemäß Fig. 3A wesentlich geringer sind als bei der deutlich tieferen Rastvertiefung 28 " in Fig. 3B.In the FIGS. 3A and 3B is the detail III in Fig. 2 shown in two different variants. The detent recess 28 'is the Fig. 3A much smaller than the locking recess 28 "in Fig. 3B whose cross-sectional shape corresponds to almost a semicircle. The different shapes make it clear that the holding forces required to unlock the locking connection in the embodiment according to Fig. 3A are much lower than in the much deeper latching recess 28 "in Fig. 3B ,

Die Fig. 4 zeigt den drehbaren Körper 4 in axialer Ansicht. Dieser drehbare Körper 4 besteht aus einem Ring 11 mit einer Innenverzahnung 13 und mit drei an der Außenseite des Ringes angeordneten Armen 10. Die Arme 10 sind aufgrund Ihrer Gestaltung und des Materials radial nach außen federnd, wobei die Darstellung in Fig. 4 die entspannte Stellung der federnden Arme 10 zeigt. An den freien Enden der federnden Arme 10 ist jeweils eine Rastnase 9 angeformt. Die federnden Arme 10 erstrecken sich im wesentlichen in Umfangsrichtung des Ringes, wobei die freien Enden im eingebauten Zustand des drehbaren Körpers 4 zum Mittelpunkt M des drehbaren Körpers 4 hin gedrückt sind. Die dadurch erzeugte Vorspannung unterstützt das Einrasten der Rastnasen 9 bei Erreichen von Rastvertiefungen in dem in den Fig. 1 und 2 gezeigten ersten Gelenkteil 5.The Fig. 4 shows the rotatable body 4 in axial view. This rotatable body 4 consists of a ring 11 with an internal toothing 13 and three arranged on the outside of the ring arms 10. The arms 10 are due to their design and the material radially outwardly resilient, the illustration in FIG Fig. 4 the relaxed position of the resilient arms 10 shows. At the free ends of the resilient arms 10, a detent 9 is formed in each case. The resilient arms 10 extend substantially in the circumferential direction of the ring, wherein the free ends are pressed in the installed state of the rotatable body 4 to the center M of the rotatable body 4 out. The bias generated thereby supports the engagement of the locking lugs 9 when reaching locking recesses in the in the Fig. 1 and 2 shown first joint part. 5

Die Fig. 5A, 5B und 5C zeigen unterschiedliche Varianten der Einzelheit V in Fig. 4. Dabei besitzt die Querschnittsform der Rastnase 9 in Fig. 5B eine Wölbung 23 mit einer im wesentlichen gleichmäßigen Krümmung, wobei die Höhe der Wölbung 23 an dem sich an den federnden Arm 10 anschließenden Ende deutlich geringer ist als auf der abgewandten Seite. In Fig. 5A besitzt die Rastnase 9 im wesentlichen die Form eines Rechtecks, wobei der Übergang zum federnden Arm 10 hin eine etwas geneigte Seitenfläche besitzt. In Fig. 5C ist eine Rastnase 9 dargestellt, die im wesentlichen eine Trapezform 24 besitzt, wobei die seitlichen Flächen des Trapezes annähernd gleiche Winkel zur Dachfläche einnehmen und sich die jeweiligen Flächen durch die unterschiedlichen Höhen zu beiden Seiten des Trapezes unterscheiden.The Figs. 5A, 5B and 5C show different variants of the detail V in Fig. 4 , The cross-sectional shape of the Latch 9 in Fig. 5B a curvature 23 with a substantially uniform curvature, wherein the height of the curvature 23 at the adjoining the resilient arm end 10 is significantly lower than on the opposite side. In Fig. 5A the locking lug 9 has substantially the shape of a rectangle, wherein the transition to the resilient arm 10 has a slightly inclined side surface. In Fig. 5C a locking lug 9 is shown, which has a trapezoidal shape 24 substantially, wherein the lateral surfaces of the trapezoid occupy approximately the same angle to the roof surface and the respective surfaces differ by the different heights on both sides of the trapezoid.

Die Fig. 6 zeigt das erste Gelenkteil 5 mit dem eingesetzten drehbaren Körper 4 in der gleichen Ansicht wie Fig. 2. Der drehbare Körper 4 ist gemäß Darstellung in Fig. 4 als ein Ring mit einer Innenverzahnung ausgeführt und die federnden Arme 10 sind am äußeren Umfang des Ringes 11 angeordnet. Wie aus Fig. 6 ersichtlich ist, befinden sich die Rastnasen 9 in den Rastvertiefungen 28 und können nur durch Überwindung der aufgrund der jeweiligen Form der Rastnasen und Rastvertiefungen sowie der von den Armen 10 ausgeübten Federkraft erzeugten Haltekraft entrastet werden. Im übrigen stimmen die Bezugszeichen mit denjenigen der zuvor beschriebenen Figuren für gleiche Teile überein.The Fig. 6 shows the first hinge part 5 with the inserted rotatable body 4 in the same view as Fig. 2 , The rotatable body 4 is shown in FIG Fig. 4 designed as a ring with an internal toothing and the resilient arms 10 are arranged on the outer circumference of the ring 11. How out Fig. 6 it can be seen, the locking lugs 9 are in the locking recesses 28 and can only be unlocked by overcoming the generated due to the respective shape of the locking lugs and locking recesses and the force exerted by the arms 10 spring force holding force. Otherwise, the reference numerals correspond to those of the previously described figures for the same parts.

Die Fig. 7 zeigt eine Ansicht des zweiten Gelenkteils 6 mit dem Zahnkranz 14, der in die in Fig. 6 gezeigte Innenverzahnung 13 des Ringes 11 greift. Bei vollständigem Zusammenfügen des ersten Gelenkteils 5 und zweiten Gelenkteils 6 befindet sich der in Fig. 7 angegebene Zapfen 15 in der aus Fig. 6 ersichtlichen Öffnung 16 im ersten Gelenkteil 5.The Fig. 7 shows a view of the second joint part 6 with the ring gear 14, which in the in Fig. 6 shown internal teeth 13 of the ring 11 engages. When fully assembled, the first joint part 5 and the second joint part 6 is located the in Fig. 7 specified pin 15 in the off Fig. 6 apparent opening 16 in the first joint part. 5

In den Fig. 8 und 9 ist eine alternative Ausführung des drehbaren Körpers 4 gezeigt, wobei dieser eine Scheibe 12 umfaßt, in der eine zentrale Bohrung 19 vorgesehen ist, durch die der Zapfen 15 des zweiten Gelenkteiles 6 greift. Es sind außerdem vier Bohrungen 20 in der Scheibe 12 vorgesehen, in die Vorsprünge des zweiten Gelenkteils ragen, um die Drehbewegung des zweiten Gelenkteils auf den drehbaren Körper 4 zu übertragen. In weiterer Abwandlung gegenüber dem zuvor beschriebenen Ausführungsbeispiel weist der drehbare Körper 4 am Umfang der Scheibe 12 vier federnde Arme 10 mit an deren freien Enden angeformten Rastnasen 9 auf. Während die Fig. 8 den drehbaren Körper 4 in der ungespannten Form, d.h. mit entlasteten Federarmen 10, zeigt, wird in Fig. 9 der eingebaute Zustand, d.h. in einer Aufnahmeöffnung 3 eingesetzt, dargestellt.In the 8 and 9 an alternative embodiment of the rotatable body 4 is shown, which comprises a disc 12 in which a central bore 19 is provided, through which the pin 15 of the second hinge part 6 engages. There are also provided four bores 20 in the disc 12 into which protrude projections of the second joint part to transmit the rotational movement of the second joint part on the rotatable body 4.
