Description

Die Erfindung betrifft eine Webmaschine mit Webschäften und Stossstangen, mit welchen die Webschäfte gekuppelt sind, wobei die Stossstangen in Verbindung mit einem Schafttrieb stehen und die Stossstangen und Schäfte je ein Kupplungsteil besitzen, welche Kupplungsteile im gekuppelten Zustand formschlüssig ineinandergreifend insgesamt die Schaftkupplung bilden, und mit einem schwenkbaren Betätigungswerkzeug zum Schliessen oder Öffnen der Kupplungen, wobei das Betätigungswerkzeug schwenkbar im Gestell der Webmaschine gelagert ist.The invention relates to a weaving machine with heald frames and bumpers, with which the heald frames are coupled, the bumpers being connected to a shaft drive and the bumpers and shafts each having a coupling part, which coupling parts form a positive interlocking engagement with the shaft coupling, and with a pivotable actuating tool for closing or opening the couplings, the actuating tool being pivotally mounted in the frame of the weaving machine.

Eine derartige Einrichtung ist in der deutschen Offenlegungsschrift Nr. 2656380 beschrieben. Das Betätigungswerkzeug wird im wesentlichen durch eine Stange mit ovalem Querschnitt gebildet und greift in eine Aussparung des schafttriebseitigen Kupplungsteils an der Stossstange ein, wenn die Schäfte gekuppelt bzw. von der Stossstange entkuppelt werden sollen. Das Betätigungswerkzeug wird dabei um 90° geschwenkt, wobei es aufgrund des ovalen Querschnittes zwei elastische Schenkel der Stossstange auseinanderdrückt.Such a device is described in German Offenlegungsschrift No. 2656380. The actuating tool is essentially formed by a rod with an oval cross-section and engages in a recess in the shaft-side coupling part on the bumper if the shafts are to be coupled or uncoupled from the bumper. The operating tool is pivoted through 90 °, pushing apart two elastic legs of the bumper due to the oval cross section.

Nachdem die Schäfte zwischen die geöffneten Schenkel der Stossstange eingefahren sind, wird das Betätigungswerkzeug um 90° weiter gedreht bzw. zurückgedreht, so dass die Kupplung geschlossen ist.After the shafts have been inserted between the opened legs of the bumper, the actuating tool is rotated further or turned back so that the coupling is closed.

Nach dem Ankuppeln der Schäfte muss das Betätigungswerkzeug aus der Webmaschine entfernt werden, da es eine Vertikalverschiebung der Stossstangen verhindert.After coupling the shafts, the operating tool must be removed from the weaving machine as it prevents the bumpers from moving vertically.

Es ist die Aufgabe der Erfindung, eine Webmaschine mit einem Betätigungswerkzeug für die Schaftkupplungen zu schaffen, welches nicht Bestandteil der Webmaschine ist und eine raumsparende Konstruktion der Schaftkupplung erlaubt.It is the object of the invention to create a weaving machine with an actuating tool for the shaft couplings, which is not part of the weaving machine and allows a space-saving construction of the shaft coupling.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Betätigungswerkzeug ein erstes und zweites Betätigungsmittel aufweist, die so gekoppelt sind, dass beide bezüglich eines gemeinsamen Schwenkzentrums diametral gegenüberliegend angeordnet und bewegbar sind und sich beidseits der Kupplungen zwischen den Webschäften und Stossstangen erstrecken, wobei das erste Betätigungsmittel in einer Schwenkbewegung von aussen gegen die Schaftkupplung bewegbar ist, um diese zu schliessen und das zweite Betätigungsmittel in einer entgegengesetzt gerichteten Schwenkbewegung von aussen gegen die Schaftkupplung bewegbar ist, um diese zu öffnen.This object is achieved according to the invention in that the actuating tool has a first and second actuating means which are coupled such that both are arranged diametrically opposite and movable with respect to a common pivoting center and extend on both sides of the couplings between the heald frames and bumpers, the first actuating means can be moved in a pivoting movement from the outside against the shaft coupling in order to close it and the second actuating means can be moved in an opposite direction pivoting movement from the outside against the shaft coupling in order to open it.

Durch die Erfindung ist es möglich, die Schäfte gleichzeitig ohne Kraftanstrengung anzukuppeln oder abzukuppeln. Die Ausführung des Betätigungswerkzeuges gestattet eine platzsparende Konstruktion der Kupplungsteile, da die Betätigungsmittel ausserhalb der Schaftkupplung angeordnet sind.The invention makes it possible to couple or uncouple the shafts at the same time without the use of force. The execution of the actuating tool allows a space-saving construction of the Coupling parts, since the actuating means are arranged outside the shaft coupling.

Das Betätigungswerkzeug kann ferner eine Antriebswelle und eine damit drehfest verbundene Kurbelwange aufweisen, das beidseits von der Antriebswelle absteht und an den freien Enden mit dem ersten bzw. zweiten Betätigungsmittel verbunden ist.The actuating tool can also have a drive shaft and a crank arm connected to it in a rotationally fixed manner, which projects on both sides of the drive shaft and is connected at the free ends to the first or second actuating means.

Um das Schliessen und Öffnen der Schaftkupplung zu gewährleisten, kann eine zweite Kurbelwange von der ersten Kurbelwange beabstandet und an seinen freien Enden mit dem ersten und zweiten Betätigungsmittel zu einem Rahmen verbunden sein, der die zwischen den Webschäften und den Stosstangen angeordneten Schaftkupplungen umgreift.In order to ensure the closing and opening of the shaft coupling, a second crank cheek can be spaced from the first crank cheek and connected at its free ends to the first and second actuating means to form a frame which encompasses the shaft couplings arranged between the heald frames and the push rods.

Die Betriebssicherheit kann verbessert werden, wenn ein Lagerzapfen an der zweiten Kurbelwange befestigt ist, der mit der Antriebswelle fluchtet.Operational safety can be improved if a bearing journal is attached to the second crank arm that is aligned with the drive shaft.

Es ist von Vorteil, wenn das Betätigungsmittel eine Achse und eine Mehrzahl von Rollen aufweist, die auf der Achse drehbeweglich angeordnet und jeweils mit einer einzelnen Schaftkupplung in und ausser Wirkverbindung bringbar sind, und dass Verbindungslaschen vorgesehen sind, die zwischen benachbarten Rollen angeordnet und mit den Achsen verbunden sind.It is advantageous if the actuating means has an axle and a plurality of rollers, which are arranged so as to be rotatable on the axle and can each be brought into and out of operative connection with a single shaft coupling, and that connecting lugs are provided which are arranged between adjacent rollers and with the Axes are connected.

Dadurch bildet das Betätigungswerkzeug einen verwindungssteifen Rost, in dessen Zwischenräumen die Schaftkupplungen bewegbar sind. Das Betätigungswerkzeug kann innerhalb der Webmaschine stationär angeordnet sein, da es in eine Ruhestellung mit horizontal gerichteten Verbindungslaschen gestellt werden kann in der die Vertikalbewegung der Stossstangen nicht behindert wird. In dieser Stellung kann es als Führungselement für einzelne Stosstangen, welche nicht an Schäfte angekuppelt sind, dienen. Die Antriebswelle der Betätigungswerkzeuge innerhalb einer Webmaschine können durch einen Antrieb, z.B. mit Ketten, untereinander und mit einem Stellantrieb verbunden sein, wobei der Stellantrieb im Schafttriebsaggregat der Webmaschine angeordnet ist.As a result, the actuating tool forms a torsion-resistant grate, in the spaces between which the shaft couplings can be moved. The actuating tool can be arranged in a stationary manner within the weaving machine since it is in a rest position with a horizontal direction Connecting tabs can be placed in which the vertical movement of the bumpers is not hindered. In this position, it can serve as a guide element for individual bumpers that are not coupled to shafts. The drive shaft of the actuating tools within a weaving machine can be connected to one another and to an actuator by a drive, for example with chains, the actuator being arranged in the shaft drive unit of the weaving machine.

Es kann eine Antriebsvorrichtung für das Betätigungswerkzeug vorgesehen werden, welche Vorrichtung eine Stelleinrichtung, ein mit dem Betätigungswerkzeug drehfest verbundenes Antriebsrad und ein mit der Stelleinrichtung und dem Antriebsrad in Wirkverbindung stehendes Übertragungsmittel aufweist. Damit kann in vorteilhafter Weise das An- bzw. Abkuppeln der Webschäfte erleichtert werden.A drive device for the actuating tool can be provided, which device has an actuating device, a drive wheel connected in a rotationally fixed manner to the actuating tool and a transmission means which is operatively connected to the actuating device and the drive wheel. The coupling or uncoupling of the heald frames can thus be facilitated in an advantageous manner.

In Figur 1 ist unten am Webschaft 1 über einem Träger 15 ein Paar Laschen 11, 11' befestigt, welche einen Bolzen 12 tragen, auf welchem sich das schaftseitige Kupplungsteil 10 befindet. Es weist unten eine Aussparung 10' sowie eine Tasche 14 mit Auflageflächen 14' und 14'' auf. Das Kupplungsteil 10 kann mit dem Webschaft 1 gemäss Richtung des Pfeils A senkrecht in das Kupplungselement 3 eingefahren werden. Das Kupplungselement besteht aus zwei Kupplungskeilen 31 und 31', welche von zwei Deckplatten 30 und 30' zusammengehalten werden. In Figur 1 ist nur die hintere Deckplatte 30 zu sehen, da das Kupplungselement 3 im Schnitt ohne vordere Deckplatte 30' gezeichnet ist. Die Kupplungskeile 30, 31 sind mit den Deckplatten 30, 30' fest verbunden, z.B. durch Buckelschweissung an den Verbindungsstellen 32. Die Platten 30 und 30' sind kreisrund, wobei jeweils ausserhalb der Kupplungskeile 31, 31' Segmente abgeschnitten sind, und haben eine zentrale Bohrung, welche eine Lagerfläche 27 auf einem Bolzen 23 bildet. Der Bolzen 23 sitzt in einer Bohrung eines Vorsprungs 20' am schafttriebseitigen Kupplungsteil 20. Der Lagerpunkt 26 des Kupplungselements 3 am unteren Kupplungsteil 20 ist also der Drehpunkt des Kupplungselements 3. Es kann durch ein Betätigungswerkzeug 5 in verschiedene Positionen gebracht werden. In Figur 1 ist das Betätigungswerkzeug 5 in Richtung des Pfeiles C gegen den Uhrzeigersinn verschwenkt worden, wobei sich das untere Kupplungsteil 20 in Offenstellung befindet. Unten am Kupplungsteil 20 ist eine Stossstange 21, welche die Hubbewegungen des Schafttriebs gemäss Figur 5 zum Schaft überträgt. Die Kupplungskeile 31 bzw. 31' haben Eingriffsflächen 35, 36 bzw. 35', 36', mit welchen sie mit Auflageflächen 14', 14'' nach Einfahren des oberen Kupplungsteils 20 im Eingriff sind. Das wird durch eine Bewegung des Betätigungswerkzeugs 5 gemäss Pfeil B in Schliesstellung gebracht.In FIG. 1, a pair of tabs 11, 11 'are fastened to the heald frame 1 below a support 15 and carry a bolt 12 on which the shaft-side coupling part 10 is located. It has a recess 10 'at the bottom and a pocket 14 with contact surfaces 14' and 14 ''. The coupling part 10 can be inserted vertically into the coupling element 3 with the heald frame 1 according to the direction of arrow A. The coupling element consists of two Coupling wedges 31 and 31 ', which are held together by two cover plates 30 and 30'. In Figure 1, only the rear cover plate 30 can be seen, since the coupling element 3 is shown in section without a front cover plate 30 '. The coupling wedges 30, 31 are firmly connected to the cover plates 30, 30 ', for example by hump welding at the connection points 32. The plates 30 and 30' are circular, segments being cut off outside the coupling wedges 31, 31 ', and have a central one Bore, which forms a bearing surface 27 on a bolt 23. The bolt 23 is seated in a bore of a projection 20 ′ on the coupling part 20 on the shaft drive side. The bearing point 26 of the coupling element 3 on the lower coupling part 20 is therefore the fulcrum of the coupling element 3. It can be brought into different positions by an actuating tool 5. In Figure 1, the actuating tool 5 has been pivoted in the direction of arrow C counterclockwise, the lower coupling part 20 being in the open position. At the bottom of the coupling part 20 is a bumper 21 which transmits the stroke movements of the shaft drive according to FIG. 5 to the shaft. The coupling wedges 31 and 31 'have engagement surfaces 35, 36 and 35', 36 ', with which they are in engagement with bearing surfaces 14', 14 '' after the upper coupling part 20 has been retracted. This is brought into the closed position by moving the actuating tool 5 according to arrow B.

Zur deutlicheren Darstellung ist in Figur 2 die Situation gemäss Figur 1 nochmals perspektivisch dargestellt, wobei nur die hintere Platte 30 des Kupplungselements 3, welche deckungsgleich mit der vorderen nicht gezeichneten Platte 30' ist, zu sehen ist. Ebenso ist nur die hintere Lasche 11, welche deckungsgleich mit einer vorderen Lasche 11' ist, gezeichnet, welche einerseits am Träger 15, der mit dem Schaft 1 verbunden ist, befestigt ist, andererseits den Bolzen 12 trägt.For a clearer illustration, the situation according to FIG. 1 is shown again in perspective in FIG. 2, only the rear plate 30 of the coupling element 3, which is congruent with the front plate 30 ', not shown, being shown. Likewise, only the rear flap 11, which is congruent with a front flap 11 ', is drawn, which on the one hand on the carrier 15, the with the shaft 1 is connected, is attached, on the other hand carries the bolt 12.

In Figur 3 sind die Kupplungsteile 10 und 20 sowie das Kupplungselement 3 im geschlossenen Zustand gezeichnet. Eine Schnappkupplung 33 gemäss Figur 3a greift im geschlossenen Zustand der Kupplungsteile 10 und 20 über die Stosstange 21, wodurch die Betriebsstellung der Kupplung gesichert ist. In der Betriebsstellung wird das Betätigungswerkzeug 5 so verschwenkt, dass die Rolle 51' des Betätigungswerkzeugs 5 in der strichpunktierten Lage in Figur 3 ist. Figur 3b stellt eine Seitenansicht der Anordnung dar, wobei insbesondere die Laschen 11 und 11' zu sehen sind, welche das schaftseitige Kupplungselement 10 tragen, sowie die Platten 30 und 30', welche die Kupplungskeile 31 und 31' zusammenhalten. Die ganze Anordnung ist sehr schlank ausgeführt, da in einer Webmaschine bis zu etwa 20 Schäfte nebeneinander angeordnet sein müssen.In Figure 3, the coupling parts 10 and 20 and the coupling element 3 are drawn in the closed state. A snap coupling 33 according to FIG. 3 a engages over the push rod 21 in the closed state of the coupling parts 10 and 20, as a result of which the operating position of the coupling is secured. In the operating position, the actuating tool 5 is pivoted such that the roller 51 'of the actuating tool 5 is in the dot-dash position in FIG. 3. FIG. 3b shows a side view of the arrangement, in particular the tabs 11 and 11 ', which carry the coupling element 10 on the shaft side, and the plates 30 and 30', which hold the coupling wedges 31 and 31 'together. The whole arrangement is very slim, since up to about 20 heald frames have to be arranged side by side in a weaving machine.

In Figur 4 wird das Betätigungswerkzeug 5 schematisch dargestellt. Es besteht im wesentlichen aus einer Antriebswelle 53, welche mit einem pneumatischen Stellantrieb 55 verbunden ist, einer Kurbelwange 54, welche mit der Antriebswelle 53 drehfest verbunden ist, sowie Achsen 52 und 52', welche Rollen 51, 51' tragen. Mittels des Stellantriebs 55 kann das Betätigungswerkzeug 5 in Richtung der Pfeile B, C verschwenkt werden. Die Leitungen 56, 56' dienen zur Zufuhr von Druckluft.The actuating tool 5 is shown schematically in FIG. It essentially consists of a drive shaft 53, which is connected to a pneumatic actuator 55, a crank arm 54, which is non-rotatably connected to the drive shaft 53, and axes 52 and 52 ', which carry rollers 51, 51'. The actuating tool 5 can be pivoted in the direction of the arrows B, C by means of the actuator 55. The lines 56, 56 'serve to supply compressed air.

Nachdem beim Artikelwechsel in der Webmaschine die Schäfte 1 gemäss Figur 5 durch ein Hubgerät in die Webmaschine eingesetzt worden sind, muss der Weber zum Ankuppeln der Schäfte lediglich einen Befehl in das Steuergerät 6 der nicht gezeichneten Webmaschine eingeben, damit der Stellantrieb 55 das Betätigungswerkzeug 5 in Schliessstellung verschwenkt. Somit sind sämtliche eingelegten Schäfte 1 mit den Stossstangen 21 des Schafttriebs 2 gekoppelt. Die Stossstangen 21 sind über Winkelhebel 22 mit Schubstangen 25 des Schafttriebes verbunden, welche ihrerseits von der nicht gezeichneten Schaftmaschine der Webmaschine betätigt werden.After the shafts 1 according to FIG. 5 have been inserted into the weaving machine by a lifting device when changing the article in the weaving machine, the weaver only has to enter a command into the control device 6 of the weaving machine, not shown, so that the actuator 55 actuates the actuating tool 5 in Closed position panned. All inserted shafts 1 are thus coupled to the bumpers 21 of the shaft drive 2. The bumpers 21 are connected via angle levers 22 to push rods 25 of the shaft drive, which in turn are actuated by the weaving machine's shaft machine, not shown.

Wie aus der Figur 3 hervorgeht, werden Zugkräfte in der Stossstange 21 von einem Kupplungsteil 10 auf das andere Kupplungsteil 20 mittels des Kupplungselements 3 an den Eingriffsflächen 36 und 36' übertragen, während Stosskräfte von einem Kupplungsteil 10 auf das andere Kupplungsteil 20 im Bereich der Aussparung 10 bzw. des Vorsprunges 20' übertragen werden.As can be seen from FIG. 3, tensile forces in the push rod 21 are transmitted from one coupling part 10 to the other coupling part 20 by means of the coupling element 3 at the engagement surfaces 36 and 36 ', while pushing forces from one coupling part 10 to the other coupling part 20 in the region of the recess 10 or the projection 20 'are transmitted.

In Figur 6 ist eine perspektivische Darstellung des Schafttriebs der Webmaschine mit dem Betätigungswerkzeug gemäss der Erfindung zu sehen. Die Webschäfte 1 sitzen zwischen zwei Schaftführungen 112, welche im Gestell 110 der Webmaschine untergebracht sind. Die Kupplungen 9 zwischen den Webschäften 1 und den Stossstangen 21 werden von den Betätigungswerkzeugen 5 umfasst. Das Betätigungswerkzeug gemäss der Erfindung kann auch für andere Ausführungsarten von Schaftkupplungen verwendet werden, bsw. für eine Schaftkupplung nach dem deutschen Patent DE 3 541 042 C1 (Grob). Das Betätigungswerkzeug 5 ist drehfest mit einem Antriebsrad 59' verbunden, welches von einem Uebertragungsglied 59, z. B. einer Kette, mit einem zweiten Antriebsrad 59' und dieses mit einem Stellantrieb 55 im Schafttriebsaggregat 21' verbunden ist. Der Stellantrieb kann entweder von Hand oder mit einem strichpunktiert angedeuteten Antriebsmotor 55' betätigt werden. Die Stossstangen 21 werden über Winkelhebel 28, diese mittels Schubstangen 29 vom Schafttriebsagregat 21 in Bewegung versetzt.FIG. 6 shows a perspective illustration of the shaft drive of the weaving machine with the actuating tool according to the invention. The heald frames 1 sit between two shaft guides 112, which are accommodated in the frame 110 of the weaving machine. The couplings 9 between the heald frames 1 and the bumpers 21 are encompassed by the actuating tools 5. The actuating tool according to the invention can also be used for other types of shaft couplings, e.g. for a shaft coupling according to the German patent DE 3 541 042 C1 (Grob). The actuating tool 5 is rotatably connected to a drive wheel 59 ', which is connected by a transmission member 59, for. B. a chain, with a second drive wheel 59 'and this is connected to an actuator 55 in the shaft drive unit 21'. The actuator can be operated either by hand or with a drive motor 55 'indicated by dash-dotted lines. The bumpers 21 are set in motion by angle levers 28, which are moved by the shaft drive unit 21 by means of push rods 29.

Figur 6a zeigt das Betätigungswerkzeug 5 in seiner Ausführungsform als Führungsrost 5'. Von der Antriebswelle 53 aus erstreckt sich quer dazu die Kurbelwange 54, in welches die Achsen 52, 52' sitzen. Diese wiederum tragen Rollen bzw. Teilrollen 51'', zwischen welchen jeweils Verbindungslaschen 58 angeordnet sind, welche fest mit den Achsen 52 und 52' verbunden sind. Am anderen Ende der Achsen 52 und 52' ist eine zweite Wange 54', welche mit einer Achse 57' verbunden ist, wobei letztere mit der Antriebswelle 53 fluchtet. Das Betätigungswerkzeug bildet so einen verwindungssteifen Rost, wobei die Teilrollen 51'' als Betätigungsmittel für die Kupplungsteile 10 und 20 dienen.Figure 6a shows the actuating tool 5 in its embodiment as a guide grate 5 '. The crank web 54, in which the axles 52, 52 ′ are seated, extends transversely from the drive shaft 53. These, in turn, carry rollers or partial rollers 51 ″, between each of which connecting straps 58 are arranged, which are firmly connected to the axes 52 and 52 ′. At the other end of the axes 52 and 52 'is a second cheek 54', which is connected to an axis 57 ', the latter being aligned with the drive shaft 53. The actuating tool thus forms a torsionally rigid grate, the partial rollers 51 ″ serving as actuating means for the coupling parts 10 and 20.

Figur 7a stellt eine offene Schaftkupplung dar, die mit einem besondern Sicherungselement 40 versehen ist, das die Funktion der Schnappkupplung 33 in Figur 3a übernimmt. Das Sicherungselement 40 besteht aus zwei Teilen 41 und 42, die gelenkig an der Stelle k miteinander verbunden sind. Das Teil 41 ist an der Stelle g beweglich mit dem schafttriebseitigen Kupplungsteil 20 verbunden und das Teil 42 ist an der Stelle d beweglich mit der Platte 30 verbunden. An der Stelle f des Teils 42 setzt eine Zugfeder 43 an, die eine Verbindung zur Stelle g des Teils 41 herstellt. Dank dieser Feder 43 weist das Sicherungselement 40 zwei stabile Stellungen auf, nämlich die Knicklage und die Strecklage, zwischen denen es hin- und herwechseln kann, wobei es eine Totpunktlage passiert. In der Totpunktlage, in der die Feder 43 am stärksten gespannt ist, liegen die drei Stellen f, k und g auf einer Geraden. Bei der offenen Schaftkupplung ist das Sicherungselement 40 in der Knicklage.FIG. 7a shows an open shaft coupling which is provided with a special securing element 40 which takes over the function of the snap coupling 33 in FIG. 3a. The securing element 40 consists of two parts 41 and 42, which are articulated at the point k. The part 41 is movably connected to the shaft drive coupling part 20 at the point g and the part 42 is movably connected to the plate 30 at the point d. At the point f of the part 42, a tension spring 43 is attached, which establishes a connection to the point g of the part 41. Thanks to this spring 43, the securing element 40 has two stable positions, namely the kink position and the extended position, between which it can switch back and forth, whereby it passes a dead center position. In the dead center position, in which the spring 43 is most tensioned, the three positions f, k and g lie on a straight line. In the open shaft coupling, the securing element 40 is in the kink position.

Nach Einschieben des schaftseitigen Kupplungsteils 10 in die offene Schaftkupplung (Pfeil A) und durch Verschwenken des Betätigungswerkzeugs 5 (Pfeil B) lässt sich die Kupplung schliessen; bei der damit verbundenen Drehbewegung des Kupplungselementes 3 wird das Sicherungselement 40 in die Totpunktlage gestreckt, wonach es in die Strecklage umschnappt. Die geschlossene Schaftkupplung ist in Figur 7b dargestellt. Dort ist auch gezeigt, wie zum öffnen der Kupplung das Betätigungswerkzeug 5 verschwenkt wird (Pfeil C), dabei auf einen seitlichen Fortsatz des Teils 42 drückt und dadurch das Sicherungselement 40 veranlasst, von der dargestellten Strecklage wieder in die Knicklage zu wechseln, wobei dieser Übergang zusammen mit der Drehbewegung des Kupplungselementes 3 stattfindet.After inserting the shaft-side coupling part 10 into the open shaft coupling (arrow A) and by pivoting the actuating tool 5 (arrow B) the clutch can be closed; with the associated rotational movement of the coupling element 3, the securing element 40 is stretched into the dead center position, after which it snaps into the extended position. The closed shaft coupling is shown in Figure 7b. There is also shown how the actuating tool 5 is pivoted to open the clutch (arrow C), thereby pressing on a lateral extension of the part 42 and thereby causing the securing element 40 to change from the stretched position shown back to the kinked position, this transition takes place together with the rotary movement of the coupling element 3.
