Description
Die Erfindung betrifft eine Gebäudeöffnungsverschattungsvorrichtung wie beispielsweise einen Rollladen, und eine Lageranordnung zur Lagerung eines motorseitigen Endes einer Wickelwelle der Gebäudeöffnungsverschattungsvorrichtung an einer Seitenwand eines Wickelwellenkastens gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a building opening shading device such as a roller shutter, and a bearing assembly for supporting a motor-side end of a winding shaft of the building opening shading device on a side wall of a winding shaft box according to the preamble of
Gebäudeöffnungsverschattungsvorrichtungen wie z.B. Rollläden weisen häufig eine motorgetriebene Wickelwelle auf. Der Motor ist dabei als Rohrmotor ausgebildet und muss sich mit seinem aus der Wickelwelle ragenden Ende drehfest abstützen. Herkömmlich wurde der Motor dazu über eine entsprechende, am Motorstirnende angebrachte Adapterplatte und dergleichen an dem zugeordneten Seitenteil des Rollladenkastens angeschraubt oder anderweitig befestigt.Building opening shading devices such as e.g. Shutters often have a motor-driven winding shaft. The engine is designed as a tubular motor and must be supported against rotation with its protruding from the winding shaft end. Conventionally, the motor has been screwed or otherwise attached to the associated side part of the roller shutter box via a corresponding, attached to the motor front end adapter plate and the like.
Bei einem Motorversagen kommt es dabei jedoch zu Problemen. Denn zum Ausbau der Wickelwelle bei aufgewickeltem Behang muss die Wickelwelle etwas gedreht werden, um den Behang ein Stück abzulassen und so den Ausbau überhaupt erst zu ermöglichen. Das wird durch einen blockierenden Motor jedoch verhindert, so dass die Befestigung des motorseitigen Wickelwellenendes an dem zugeordneten Seitenteil gelöst werden muss, was oft schwierig ist, weil die Befestigung unzugänglich ist und was ferner dazu führt, dass die Wickelwelle mit ihrem gesamten Gewicht vom Monteur gehalten werden muss.In a motor failure, however, there are problems. Because to remove the winding shaft with wound curtain, the winding shaft must be rotated slightly to drain the curtain a piece and so to allow the expansion in the first place. This is prevented by a blocking motor, however, so that the attachment of the motor-side winding shaft end must be solved on the associated side part, which is often difficult because the attachment is inaccessible and what further causes the winding shaft held with its entire weight by the fitter must become.
Neuere Lösungen sehen daher Motorlagerungen vor, bei denen die Wickelwelle mit ihrem motorseitigen Ende zum Einen in einer entsprechenden Wellenaufnahme abgestützt ist, so dass die Wellenaufnahme das Gewicht der Wickelwelle aufnimmt. Zum Anderen weisen diese Lösungen Drehverriegelungseinrichtungen auf, die das motorseitige Wickelwellenende in der Wellenaufnahme drehfest festlegen, sich zu Revisionszwecken aber wieder lösen lassen, so dass sich die Wickelwelle auch bei blockierendem Motor vom Monteur nach dem Lösen der Drehverriegelung soweit verdrehen lässt, dass ein Ausbau unproblematisch möglich ist.Therefore, newer solutions provide engine mounts in which the winding shaft with its engine-side end on the one hand in a corresponding Shaft support is supported, so that the shaft receiving the weight of the winding shaft. On the other hand, these solutions on rotary locking devices that fix the motor side winding shaft end rotatably in the shaft recording, but can be solved again for revision purposes, so that the winding shaft can twist as far as lock motor even after locking the loosening of the twist lock that a removal unproblematic is possible.
So zeigt beispielsweise die internationale Patentanmeldung
Während dabei die radial nach innen ragenden Vorsprünge am ringförmigen Adapter eine Drehung der Wickelwelle nur in einem eng begrenzten Winkelsegment zulassen, zeigt die deutsche Patentanmeldung
Der Bereich im Wickelwellenkasten, in dem zum Lösen der Drehsicherung hantiert werden muss, ist jedoch trotz dieser Verbesserung schlecht zugänglich und das Lösen des Verriegelungsstücks schwierig, zumal gleichzeitig die Wickelwelle an einer unkontrollierten Drehung gehindert werden muss und das Sicherungsstück nicht an der Motorlagerung angebracht ist, sondern nach dem Abziehen abfallen kann. Zudem handelt es sich bei der Verdrehsicherung für das motorseitige Ende der Wickelwelle um ein äußerst sicherheitskritisches Element des Rollladens bzw. der Gebäudeöffnungsverschattungsvorrichtung insgesamt.The area in the winding shaft box, in which must be handled to release the rotation lock, however, is difficult to access despite this improvement and the release of the locking piece difficult, especially at the same time the winding shaft must be prevented from uncontrolled rotation and the securing piece is not attached to the engine mount, but can fall off after subtracting. In addition, the anti-twist device for the motor-side end of the winding shaft is an extremely safety-critical element of the roller shutter or the building opening shading device as a whole.
Andere Lösungen sehen daher an den radial einschiebbaren Sicherungsriegeln, über die sich die Wickelwelle an ihrem motorseitigen Ende drehfest setzen lässt, Sicherungsfedern vor, welche den Riegel gegen ein unerwünschtes Herausziehen aus der radial eingesteckten Drehsicherungsposition sichern.Other solutions therefore see on the radially retractable Sicherungsriegeln over which the winding shaft at its motor-side end can be fixed against rotation, securing springs, which secure the bolt against unwanted extraction from the radially inserted rotational securing position.
So zeigt die deutsche Patentanmeldung
Die europäische Patentanmeldung
Eine funktional ähnliche Lageranordnung zeigt die europäische Patentschrift
Aufgabe der vorliegenden Erfindung ist es daher, eine Lageranordnung für das motorseitige Ende einer Wickelwelle bzw. eine Gebäudeöffnungsverschattungsvorrichtung mit einer solcherart gelagerten Wickelwelle zu schaffen, bei der der radial verschiebbare Drehsicherungsriegel in seiner Sicherungsstellung mit einem Sicherungsmechanismus gehalten ist, welcher zuverlässig und konstruktiv einfach ist und im Wartungsfall ein einfaches Lösen des Drehsicherungsriegels erlaubt.Object of the present invention is therefore to provide a bearing assembly for the motor-side end of a winding shaft or a Gebäudeöffnungsverschattungsvorrichtung with such a mounted winding shaft, in which the radially displaceable anti-rotation lock is held in its securing position with a locking mechanism, which is reliable and structurally simple and in case of maintenance, a simple release of the anti-rotation bolt is allowed.
Diese Aufgabe wird hinsichtlich der Lageranordnung mit den Merkmalen des Anspruchs 1 gelöst, hinsichtlich der Gebäudeöffnungsverschattungsvorrichtung mit den Merkmalen des Anspruchs 14.This object is achieved with regard to the bearing arrangement having the features of
In an sich bekannter Weise weist die erfindungsgemäße Lageranordnung eine in eine kastenseitige Wellenaufnahme einschiebbare, motorseitig anbringbare Adapterscheibe auf, die dort bajonettverschlussartig gegen axiales Herausziehen gesichert aufgenommen ist und über eine Drehsicherungseinrichtung drehfest setzbar ist, wobei die Drehsicherungseinrichtung einen radial verschiebbaren Sicherungsriegel aufweist, der in seiner Drehsicherungsstellung die Wellenaufnahme und die darin eingeschobene Adapterscheibe drehfest aneinander festlegt und in seiner Drehfreigabestellung eine Drehung der Adapterscheibe - und damit der Wickelwelle, auch bei blockierendem Motor - zulässt, und wobei eine Sicherungsfeder vorgesehen ist, die den Sicherungsriegel in seiner Drehsicherungsstellung sichert. Die erfindungsgemäße Lageranordnung zeichnet sich dabei dadurch aus, dass die Sicherungsfeder an der Wellenaufnahme angebracht ist und der Sicherungsriegel über die Sicherungsfeder an der Wellenaufnahme hängt. Dadurch gelingt eine einfache Vormontage der Drehsicherungseinrichtung an der Wellenaufnahme bereits ab Fabrik, so dass die aus dem Sicherungsriegel und der Sicherungsfeder bestehende Drehsicherungseinrichtung während des Transports bereits an der Wellenaufnahme verliersicher angebracht sein kann und auf der Baustelle eine einfache Endmontage möglich ist.In a conventional manner, the bearing assembly according to the invention has an insertable into a box-side shaft mount, motor side attachable adapter disc, which is recorded there secured bayonet locking against axial withdrawal and rotationally fixed via a rotation locking device can be placed, wherein the rotation locking device has a radially displaceable locking latch in his Anti-rotation position, the shaft holder and the inserted therein adapter disc rotatably fixed together and in its rotational release position rotation of the adapter plate - and thus the winding shaft, even with blocking motor - allows, and wherein a securing spring is provided which secures the fuse latch in its anti-rotation position. The bearing arrangement according to the invention is characterized in that the securing spring is attached to the shaft receptacle and the securing latch hangs on the shaft receptacle via the securing spring. This makes it easy to pre-assemble the anti-rotation device on the shaft mount already ex factory, so that the existing of the locking latch and the locking spring rotation device can already be mounted captive during transport already on the shaft mount and on site a simple final assembly is possible.
Dadurch gelingt nicht nur ein konstruktiv einfacher Aufbau des Sicherungsriegels und der Lageranordnung insgesamt, weil der Sicherungsriegel keine irgendwie angeformte Sicherungsfeder aufweisen muss und daher in geometrisch äußerst einfacher Form gestaltet sein kann, wohingegen die Sicherungsfeder sich bereits vorab an der Wellenaufnahme anbringen bzw. montieren oder befestigen lässt, sondern auch eine einfache Montage der Wickelwelle am motorseitigen Kastenteil bei gleichzeitig zuverlässiger Drehsicherung während des Betriebs der Gebäudeöffnungsverschattungsvorrichtung und einfachem Lösen der Drehsicherung im Wartungsfall. Denn zur Montage kann zunächst die Haltefeder an der Wellenaufnahme vormontiert werden, dann die Wickelwelle mit ihrem motorseitigen Ende und der daran befestigten Adapterplatte in die Wellenaufnahme eingeschoben und durch Verdrehen mit den Hintergriffslaschen an den Haltelaschen gegen axiales Herausziehen gesichert werden, woraufhin der Sicherungsriegel in Ansatz gebracht und mit der Sicherungsfeder verbunden werden kann.This not only succeeds in a structurally simple construction of the safety bolt and the bearing assembly as a whole, because the safety latch must not have any molded safety spring and therefore can be designed in geometrically extremely simple form, whereas the safety spring already attach to the shaft mount or mount or fasten leaves, but also a simple installation of the winding shaft on the motor-side box part with reliable rotation while operating the building opening shading device and easy release the rotation lock in case of maintenance. Because for mounting the retaining spring can first be pre-assembled on the shaft mount, then the winding shaft inserted with its motor-side end and the attached adapter plate in the shaft mount and by twisting with the rear grip tabs be secured to the retaining tabs against axial withdrawal, whereupon the locking latch can be brought into approach and connected to the locking spring.
Es wäre denkbar, die Sicherungsfeder und den Sicherungsriegel einstückig auszubilden.It would be conceivable to form the securing spring and the securing bolt in one piece.
Eine vorteilhafte Weiterbildung der übergeordneten Maßnahmen zeichnet sich dadurch aus, dass durch die zweiteilige Ausbildung von Sicherungsfeder und Sicherungsriegel zudem für jedes der beiden Bauteile ein geeignetes Material gewählt werden kann. So ist die Sicherungsfeder vorteilhaft als Drahtfeder aus Metalldraht ausgebildet. Der Sicherungsriegel kann dagegen aus Kunststoff bestehen.An advantageous development of the higher-level measures is characterized by the fact that a suitable material can also be selected for each of the two components by the two-part design of safety spring and safety latch. Thus, the locking spring is advantageously designed as a wire spring made of metal wire. The safety catch, on the other hand, can be made of plastic.
Weiterhin vorteilhaft weist die Adapterscheibe eine Anzahl radial verlaufender Riegelaufnahmen auf und die Wellenaufnahme an ihrem zylindrischen Umfangsabschnitt eine weitere Anzahl sich radial öffnender Riegelöffnungen, wobei der Sicherungsriegel in seiner Drehsicherungsstellung in eine der Anzahl der Riegelaufnahmen an der Adapterscheibe und in eine der weiteren Anzahl sich radial öffnender Riegelöffnungen eingreift, um die Adapterscheibe an der Wellenaufnahme drehfest festzulegen. Weiterhin vorteilhaft ist es dabei, wenn der Eingriff mit ausschließlichem Freiheitsgrad in Radialverschieberichtung des Riegels erfolgt, d.h., wenn der Riegel mehr oder weniger als Passstift ausgebildet ist, welcher in jede Riegelaufnahme und jede Riegelöffnung passt. Im Sinne eines einfachen Hineinschiebens bzw. Herausziehens des Riegels in seine Drehsicherungsstellung bzw. in seine Drehfreigabestellung ist es dabei jedoch wünschenswert, wenn die Passung ein gewisses, im Hinblick auf die drehfeste Verriegelung aber nicht zu großes Spiel aufweist.Further advantageously, the adapter disc has a number of radially extending latch receptacles and the shaft receptacle on its cylindrical peripheral portion a further number of radially opening latch openings, wherein the locking latch in its rotational securing position in one of the number of latch receptacles on the adapter disc and in one of the further number radially opening Lock openings engages to fix the adapter disc on the shaft receiving rotation. In this case, it is further advantageous if the engagement with exclusive degree of freedom takes place in the direction of radial displacement of the bolt, that is, if the bolt is more or less designed as a dowel pin which fits into each bolt receptacle and each bolt opening. In terms of a simple insertion or extraction of the bolt in its anti-rotation position or in its rotational release position, however, it is desirable if the fit has a certain, in terms of non-rotatable locking but not too big game.
Besonders bevorzugt ist es dabei, wenn der zylindrische Umfangsabschnitt der Wellenaufnahme an einer rohrstummelartig von der stirnseitigen Kastenseitenwand abstehenden Umfangswand ausgebildet ist. An der Umfangswand kann dann die als weitere Anzahl Radialdurchbrüche ausgebildete, weitere Anzahl Riegelöffnungen vorgesehen sein. Der Sicherungsriegel kann dann zumindest in seiner Drehsicherungsstellung einen der weiteren Anzahl Radialdurchbrüche durchgreifen, so dass die Sicherungsfeder an seinem radial außerhalb der Umfangswand gelegenen Abschnitt angebracht sein kann.It is particularly preferred in this case if the cylindrical peripheral portion of the shaft receptacle is formed on a circumferential wall projecting from the end-side box side wall like a pipe stub. At the Circumferential wall can then be designed as a further number of radial openings formed, more number of bolt openings. The securing bolt can then pass through at least one of the further number of radial openings in its anti-rotation position, so that the securing spring can be attached to its section located radially outside the circumferential wall.
Um den Riegel gegen ein Herausziehen in Axialrichtung der Wickelwelle zu schĂĽtzen, kann dabei eine der weiteren Anzahl RadialdurchbrĂĽche zugeordnete, an jedem Radialdurchbruch jeweils radial auĂźenseitig angeordnete weitere Anzahl in Radialrichtung verlaufender FĂĽhrungsbahnen vorgesehen sein, in der der Sicherungsriegel in seiner Drehsicherungsstellung und in seiner Drehfreigabestellung vorzugsweise mit ausschlieĂźlichem Freiheitsgrad in seine Radialverschieberichtung gefĂĽhrt aufgenommen ist.In order to protect the bolt against being pulled out in the axial direction of the winding shaft, one of the further number of radial openings assigned to each radial breakthrough each radially outwardly arranged further number can be provided in the radial direction extending guideways, in which the locking latch in its anti-rotation position and in its rotational release position preferably is recorded guided in its radial displacement direction with exclusive degree of freedom.
Um die Sicherungsfeder an der Wellenaufnahme anzubringen, kann die Sicherungsfeder vorteilhaft einen Ringfederabschnitt aufweisen, der ĂĽber die von der Seitenwand abstehende Umfangswand gezogen ist. Dadurch ist die Sicherungsfeder zum Einen in der Wellenaufnahme angebracht bzw. befestigt. Zum Anderen kann sich der Ringfederabschnitt bei Zug an dem mit der Sicherungsfeder verbundenen Sicherungsriegel elastisch verformen und den Riegel zu seiner Drehsicherungsstellung hin, also nach radial innen hin, vorspannen.In order to attach the securing spring to the shaft receiving means, the securing spring can advantageously have a ring spring section which is pulled over the peripheral wall projecting from the side wall. As a result, the securing spring is mounted or fastened on the one hand in the shaft mount. On the other hand, the annular spring portion can deform elastically in train on the securing bolt connected to the locking bolt and bias the bolt towards its anti-rotation position, ie radially inward.
Um den Ringfederabschnitt auf der Umfangswand gegen ein Abrutschen in Axialrichtung zum Kasteninneren hin zu sichern, kann die Umfangswand vorteilhaft eine Mehrzahl auĂźen umfangsseitig nach radial auĂźen vorstehender Federhaltelaschen aufweisen, und einen auĂźen umfangsseitig nach radial auĂźen vorstehenden, umlaufenden Federhaltekragen.In order to secure the annular spring portion on the peripheral wall against slipping in the axial direction to the box inside, the peripheral wall may advantageously have a plurality of circumferentially outwardly radially projecting spring retaining tabs, and an outer circumferentially radially outwardly projecting, circumferential Federhaltekragen.
Die Sicherungsfeder kann ferner einen an den Ringfederabschnitt auf Seiten des Sicherungsriegels anschließenden Einhängbügelabschnitt aufweisen, mit dem die Sicherungsfeder an dem Sicherungsriegel befestigt ist. Dazu kann der Sicherungsriegel eine quer zu seiner Radialverschieberichtung verlaufende, hinterschnittene Hakennut oder einen entsprechenden Haken aufweisen, an der die Sicherungsfeder mit ihrem Einhängbügelabschnitt eingehängt ist.The safety spring may further comprise a subsequent to the annular spring portion on the side of the locking bolt Einhängbügelabschnitt with which the securing spring is attached to the locking latch. This can be the Securing latch have a transversely extending to its Radialverschieberichtung, undercut hook groove or a corresponding hook on which the securing spring is hung with her Einhängbügelabschnitt.
Da der Bereich im Kasteninneren, in dem sich der Sicherungsriegel befindet, im Revisionsfall schwer zugänglich ist, selbst wenn der Sicherungsriegel vorteilhaft mit von der Wellenaufnahme aus schräg nach unten gerichteter Radialverschieberichtung an der Wellenaufnahme aufgenommen ist, ist an dem Sicherungsriegel besonders bevorzugt ein nach unten hängendes Betätigungselement zweckmäßig als Seil, Schnur, Draht etc. befestigt, welches dann in einen im Revisionsfall besser zugänglichen Bereich des Rollladenkastens oder sogar durch die geöffnete Revisionsklappe aus dem Rollladenkasten heraushängt. Dazu kann der Sicherungsriegel an seinem unteren Ende eine zum Anbringen des Betätigungselements vorgesehene Öse aufweisen.Since the area in the box inside, in which the locking latch is difficult to access in case of revision, even if the locking bolt is advantageously received with the shaft receiving obliquely downwardly directed Radialverschieberichtung on the shaft receiving, is particularly preferably a down-hanging on the locking latch Actuator expediently attached as a rope, string, wire, etc., which then hangs out in a better accessible in case of revision area of the roller shutter box or even through the open inspection flap from the shutter box. For this purpose, the securing bolt may have at its lower end an eyelet provided for attaching the actuating element.
Eine weitere vorteilhafte Weiterbildung betrifft eine Lagerplatte, an der die Wellenaufnahme angebracht ist und welche an einem Seitenteil des Wickelwellenkastens befestigbar ist. Die Lagerplatte bildet dann zusammen mit dem Kastenseitenteil die stirnseitige Seitenwand, an der das motorseitige Wickelwellenende gelagert werden soll und damit einen Teil der Lageranordnung im Sinne der vorliegenden Anmeldung. Vorteilhaft ist dabei an dem Seitenteil eine Plattenaufnahme vorgesehen, in die die Lagerplatte von der im eingebauten Zustand der Wickelwelle zugewandten Seite her in Richtung der Wellenachse, also frontal einsetzbar ist, wobei die Lagerplatte mit ihrem in die Plattenaufnahme einsetzbaren, plattenförmigen Flachkörper die Wellenaufnahme trägt, so wie vorzugsweise die rohrstummelartig an den Flachkörper angeformte Umfangswand. Kastenseitenteile mit einer solchen, normierten Plattenaufnahme können dann im Sinne einer hohen Gleichteiligkeit für verschiedene Gebäudeöffnungsverschattungsvorrichtungen verwendet werden. Im Sinne einer noch höheren Gleichteiligkeit ist es dabei vorteilhaft, wenn die Lageranordnung ein Einsetzen und ein dreh- und ortsfestes Festlegen der Lagerplatte in der Plattenaufnahme in genau zwei Stellungen zulässt, einer Standardstellung und einer demgegenüber um 180° um die Wellenachse gedrehten Variantenstellung, wobei die Wellenaufnahme an einer solchen außermittigen Position auf dem Flachkörper der Lagerplatte angeordnet ist, dass sie bei in Variantenstellung in der Plattenaufnahme festgelegter Lagerplatte einen Versatz zur Position der Wellenaufnahme bei in Standardstellung in der Plattenaufnahme festgelegter Lagerplatte aufweist. Denn dann kann die Lageranordnung mit unterschiedlichen Kastenseitenteilen verwendet werden, d.h. in unterschiedlichen Rollladenkästen, die eine unterschiedliche Positionierung der Wickelwelle erfordern.A further advantageous embodiment relates to a bearing plate on which the shaft receptacle is mounted and which can be fastened to a side part of the winding shaft box. The bearing plate then forms, together with the box side part, the end-side side wall, on which the motor-side winding shaft end is to be stored, and thus a part of the bearing arrangement in the sense of the present application. Advantageously, a plate receptacle is provided on the side part, in which the bearing plate of the mounted in the state of the winding shaft facing side in the direction of the shaft axis, ie frontally inserted, the bearing plate with its insertable into the disk holder, plate-shaped flat body carries the wave recording, as well as preferably the pipe stub-like integrally formed on the flat body peripheral wall. Box side panels with such a normalized panel mount can then be used to provide high uniformity for various building opening shading devices. In terms of even higher common parts, it is advantageous if the bearing assembly allows insertion and a rotational and stationary fixing of the bearing plate in the disc holder in exactly two positions, a standard position and a contrast rotated by 180 ° about the shaft axis variant position, wherein the shaft mount is arranged at such an eccentric position on the flat body of the bearing plate that they set in variant position in the disk holder bearing plate determined an offset to the position of the shaft recording in the standard position in the disk holder Has bearing plate. Because then the bearing assembly can be used with different box side parts, ie in different shutter boxes, which require a different positioning of the winding shaft.
Insbesondere im Hinblick auf die um 180° drehbare Lagerplatte ist es dabei vorteilhaft, wenn an der Wellenaufnahme, also bevorzugt an der rohrstummelartig von dem Flachkörper der Lagerplatte abstehenden Umfangswand, nicht nur eine, sondern mehrere Riegelöffnungen vorgesehen sind, für die 180°-Drehbarkeit zumindest zwei sich radial gegenüberliegende Riegelöffnungen, so dass der Sicherungsriegel mit nach unten, bzw. schräg nach unten verlaufender Radialverschieberichtung an der Lagerplatte angebracht werden kann.In particular with regard to the rotatable by 180 ° bearing plate, it is advantageous if not only one, but a plurality of locking holes are provided on the shaft receiving, so preferably on the tubular stubby protruding from the flat body of the bearing plate peripheral wall, for the 180 ° rotation at least two radially opposing bolt openings, so that the securing bolt can be attached to the bearing plate with downward or obliquely downward Radialverschieberichtung.
Die erfindungsgemäße oder vorteilhaft weitergebildete Gebäudeöffnungsverschattungsvorrichtung, insbesondere ein Rollladen, weist eine Lageranordnung mit den erfindungsgemäßen Merkmalen oder den Merkmalen einer vorstehend beschriebenen, vorteilhaften Weiterbildung auf, um das motorseitige Ende ihrer Wickelwelle an einem Kastenseitenteil drehfest abzustützen.The invention or advantageously further developed Gebäudeöffnungsverschattungsvorrichtung, in particular a roller shutter, has a bearing assembly with the features of the invention or the features of an advantageous development described above, to support the motor-side end of its winding shaft on a box side member rotatably.
Zur Montage und insbesondere auch zur Demontage im Revisionsfall ist es dabei vorteilhaft, wenn die Wickelwelle an ihrem anderen, motorabgewandten Ende einen in Axialrichtung verschiebbaren Lagerbolzen aufweist, und sich so aus der Wellenaufnahme ziehen lässt.For assembly and in particular also for disassembly in the case of revision, it is advantageous if the winding shaft has at its other end facing away from the engine an axially displaceable bearing pin, and thus can be pulled out of the shaft receiving.

Im Revisionsfall wird der Riegel mittels des Betätigungsseils 15 etc. also aus seiner Drehsicherungsstellung in seine Drehfreigabestellung herausgezogen, so dass er sich nicht mehr in Eingriff an der Lagerschale befindet. Wird nun die Welle ein kleines Stück gedreht, kann der Sicherungsriegel 7a wieder losgelassen werden. Dieser liegt nun am Umfang der Adapterschale 3 an und gleitet an selbigem entlang. Die Welle kann nun frei gedreht werden, bis der Sicherungsriegel 7a aufgrund der Federkraft der Sicherungsfeder 7b selbstständig in eine der Riegelaufnahmen 3b an der Adapterschale 3 zurückspringt, im dargestellten Beispiel mit zwei Riegelaufnahmen 3b an der Adapterschale also nach einer 180°-Drehung der Wickelwelle.
