Description

Die Erfindung bezieht sich auf eine Aufzugseinrichtung für das Schlagwerk einer Repetieruhr, mit einem von einem Uhrgehäuse nach außen hervorstehenden Betätigungsteil, das als ein entlang der Gehäusewand geführter Betätigungsschieber ausgebildet ist, das durch eine Öffnung in das Gehäuseinnere ragt und das entgegen einer Federkraft entlang einer Bewegungsbahn an der Gehäuseaußenseite bewegbar ist, wodurch ein Bauteil des Schlagwerks bewegbar ist.The invention relates to an elevator device for the striking mechanism of a repeater watch, with an actuating part protruding outward from a watch case, which is designed as an actuating slide guided along the case wall, which projects through an opening into the inside of the case and which counteracts a spring force along a movement path is movable on the outside of the housing, whereby a component of the striking mechanism can be moved.

Bei derartigen bekannten Aufzugseinrichtungen besteht das Problem, daß sie einen erheblichen Raumbedarf erfordern. Dies ist insbesondere dann von Nachteil, wenn es sich bei der Repetieruhr um eine Armbanduhr handelt, da dort üblicherweise wenig Einbauraum zur Verfügung steht.The problem with such known elevator devices is that they require a considerable amount of space. This is particularly disadvantageous if the repeater watch is a wristwatch, since there is usually little installation space available there.

Aus der CH-A-46 356, der US-A-367 995, der CH-A-672 868 sowie der CH-A-54 713 sind Aufzugseinrichtungen der eingangs genannten Art bekannt. Dabei besitzen die Betätigungsschieber Anschläge, die innerhalb der Uhrengehäuse ein Bauteil des Schlagwerkes direkt beaufschlagen. Dies erfordert sich entlang des gesamten radial umlaufenden Bewegungsweges des Betätigungsschiebers erstreckende Öffnungen, die eine sichere Abdichtung des Gehäuseinneren nach außen nicht zulassen.Elevator devices of the type mentioned at the outset are known from CH-A-46 356, US-A-367 995, CH-A-672 868 and CH-A-54 713. The actuating slides have stops that act directly on a component of the striking mechanism within the watch case. This requires openings extending along the entire radially circumferential movement path of the actuating slide, which openings do not permit reliable sealing of the interior of the housing from the outside.

Aufgabe der Erfindung ist es, eine Aufzugseinrichtung der eingangs genannten Art zu schaffen, die einen geringen Raumbedarf erfordert sowie auf einfache Weise eine sichere Abdichtung des Gehäuseinneren nach außen gewährleistet.The object of the invention is to provide an elevator device of the type mentioned at the outset, which requires little space and, in a simple manner, ensures reliable sealing of the interior of the housing from the outside.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Betätigungsschieber einen Anschlag aufweist, durch den ein in einer sich etwa tangential in der Gehäusewand erstreckenden und mit ihrem einen Ende zum Bereich des Anschlags hin nach außen mündenden Bohrung verschiebbar angeordneter Betätigungsbolzen etwa in Erstreckungsrichtung der Gehäusewand bewegbar ist, wobei der Betätigungsbolzen einen radial in das Gehäuseinnere hervorstehenden Mitnehmer aufweist, durch den das Bauteil des Schlagwerks bewegbar ist.This object is achieved in that the actuating slide has a stop, by means of which an actuating bolt, which extends in an approximately tangential manner in the housing wall and with one end opening towards the region of the stop and is displaceable, can be moved approximately in the direction of extension of the housing wall , wherein the actuating pin has a radially projecting into the housing interior driver through which the component of the striking mechanism can be moved.

Weiterhin ist die das Gehäuseinnere mit dem Gehäuseäußeren verbindende Öffnung auf die Querschnittsfläche des Betätigungsbolzens beschränkt, was den Vorteil hat, daß eine Öffnung derartig geringen Querschnitts auf relativ einfache Weise sicher abdichtbar ist.Furthermore, the opening connecting the interior of the housing to the exterior of the housing is limited to the cross-sectional area of the actuating bolt, which has the advantage that an opening of such a small cross-section can be reliably sealed in a relatively simple manner.

Diese Ausbildung führt zu einer Anordnung, die nicht in das Gehäuseinnere hineinragt, sondern im wesentlichen in der Gehäusewand des Uhrgehäuses angeordnet ist. Einziges in das Gehäuseinnere ragendes Bauteil ist der Mitnehmer des Betätigungsbolzens. Zu der geringen Baugröße trägt auch die flach bauende Ausbildung des Betätigungsteils als Betätigungsschieber bei.This design leads to an arrangement which does not protrude into the interior of the case, but is essentially arranged in the case wall of the watch case. The only component protruding into the housing interior is the driver of the actuating bolt. The flat design of the actuating part as an actuating slide also contributes to the small size.

Vorzugsweise ist der Betätigungsbolzen an seiner nach außen ragenden Stirnseite von dem Anschlag des Betätigungsschiebers beaufschlagbar. Damit erfolgt die Beaufschlagung axial und vermeidet ein Verkanten des Betätigungsbolzens.The actuating bolt can preferably be acted upon by the stop of the actuating slide on its outwardly projecting end face. The actuation is thus carried out axially and prevents the actuating bolt from tilting.

Die Bewegungsbahn des Betätigungsschiebers und die Erstreckung der Ausnehmung für den Betätigungsbolzen kann um ein geringes Maß von einer Parallelität zueinander abweichen, was z. B. dadurch gegeben ist, daß die Bewegungsbahn des Betätigungsschiebers eine Bogenbahn entlang der Gehäuseaußenseite des mit rundem Querschnitt ausgebildeten Uhrgehäuses ist.The path of movement of the actuating slide and the extent of the recess for the actuating bolt can deviate to a small extent from parallelism to one another, which, for. B. is given in that the path of movement of the actuating slide is an arc along the outside of the housing of the watch case formed with a round cross section.

Ist in der Bohrung an ihrer Mündungsöffnung nach außen ein Führungsring angeordnet, durch den der Betätigungsbolzen nach außen ragt, so kann der Querschnitt der Öffnung besonders gering gehalten werden, was die Abdichtbarkeit noch weiter erleichtert.If a guide ring is arranged in the bore at its mouth opening to the outside, through which the actuating bolt protrudes outwards, the cross section of the opening can be kept particularly small, which further facilitates the sealability.

Eine einfache Möglichkeit der Abdichtung wird dadurch erreicht, daß an der Innenwand des Führungsrings eine radial umlaufende Ringnut ausgebildet ist, in der ein den Betätigungsbolzen dicht umschließender Dichtungsring angeordnet ist.A simple way of sealing is achieved in that a radially circumferential annular groove is formed on the inner wall of the guide ring, in which a sealing ring tightly enclosing the actuating bolt is arranged.

Eine Federbeaufschlagung des Betätigungsbolzens und des Betätigungsschiebers erfolgt in einfacher Weise dadurch, daß eine mit ihrem einen Ende an dem der Mündungsöffnung entgegengesetzten Ende der Bohrung abgestützte, in der Bohrung angeordnete Druckfeder mit ihrem anderen Ende den Betätigungsbolzen zum Gehäuseäußeren hin beaufschlagt.Spring actuation of the actuating bolt and of the actuating slide takes place in a simple manner in that a pressure spring, which is supported with its one end at the end of the bore opposite the mouth opening, arranged in the bore with its other end acts on the actuating bolt towards the exterior of the housing.

Damit der Betätigungsbolzen bei seiner Verstellung eine definierte Bewegungsbahn einhält, kann der Betätigungsbolzen in der Bohrung bewegbar geführt sein.So that the actuating bolt maintains a defined path of movement when it is adjusted, the actuating bolt can be guided movably in the bore.

Ragt der Mitnehmer durch einen sich entlang seiner Bewegungsbahn erstreckenden Führungsschlitz, der eine die Bohrung mit dem Gehäuseinneren verbindende Öffnung bildet, so ist er gegen Verdrehen um die Längsachse des Betätigungsbolzens und damit gegen Außereingriffkommens von dem Bauteil des Schlagwerkes gesichert.If the driver protrudes through a guide slot extending along its path of movement, which forms an opening connecting the bore to the interior of the housing, it is secured against rotation about the longitudinal axis of the actuating bolt and thus against disengagement from the component of the striking mechanism.

Zum leichten Einbau der Druckfeder und des Betätigungsbolzens kann im der Mündungsöffnung entgegengesetzten Endbereich der Bohrung eine von der Bohrung ausgehende, sich um Gehäuseinneren erstreckende Montageöffnung ausgebildet sein. Diese Ausbildung hat auch den Vorteil, daß keine nur schwer abdichtbare Öffnung zum Gehäuseäußeren hin erforderlich ist.For easy installation of the compression spring and the actuating bolt can be placed in the opposite opening End region of the bore, a mounting opening extending from the bore and extending around the interior of the housing can be formed. This design also has the advantage that no opening to the housing exterior that is difficult to seal is required.

Vorzugsweise mündet der Führungsschlitz in die Montageöffnung, so daß auch das Einführen des Mitnehmers in den Führungsschlitz beim Einführen des Betätigungsbolzens in die Bohrung auf einfache Weise möglich ist.The guide slot preferably opens into the assembly opening, so that the insertion of the driver into the guide slot is also possible in a simple manner when the actuating bolt is inserted into the bore.

Ebenfalls zur Vereinfachung der Montage dient es, wenn der Betätigungsbolzen axial aufeinandersteckbar mehrteilig ausgebildet ist. Dadurch ist es auch nicht nötig, eine große Montageöffnung vorzusehen.It also serves to simplify the assembly if the actuating bolt is designed to be axially pluggable in several parts. It is therefore not necessary to provide a large assembly opening.

Um eine Abnutzung durch Reibung der aneinanderliegenden Flächen von Betätigungsschieber und Betätigungsbolzen weitgehend zu vermeiden, kann der Anschlag des Betätigungsschiebers eine aus einem verschleißfesten und reibungsarmen Werkstoff bestehende Anlagefläche für den Betätigungsbolzen aufweisen.In order to largely avoid wear due to friction between the surfaces of the actuating slide and the actuating bolt, the stop of the actuating slide can have a contact surface for the actuating bolt which is made of a wear-resistant and low-friction material.

Vorzugsweise wird dies dadurch erreicht, daß die Anlagefläche durch einen in eine Ausnehmung des Betätigungsschiebers eingesetzten Amboßblock gebildet ist, wobei der Amboßblock aus Keramik bestehen bzw. ein Safir sein kann.This is preferably achieved in that the contact surface is formed by an anvil block inserted into a recess of the actuating slide, the anvil block being made of ceramic or being a Safir.

Insbesondere, wenn bei Betätigung der Aufzugseinrichtung eine Relativbewegung zwischen dem Anschlag des Betätigungsschiebers und dem Betätigungsbolzen quer zu dessen Längsachse erfolgt, kann die Anlagefläche eine derartige Kurvenkorrektur besitzen, daß in jeder Position des Betätigungsschiebers eine axiale Beaufschlagung des Betätigungsbolzens erfolgt.In particular, if, when the elevator device is actuated, there is a relative movement between the stop of the actuating slide and the actuating bolt transversely to its longitudinal axis, the contact surface can have such a curve correction that in Each position of the actuating slide is axially acted upon by the actuating bolt.

Zur Führung kann der Betätigungsschieber mittels einer Schubführung an der Gehäuseaußenwand verschiebbar geführt sein. Ist dabei die Schubführung eine Prismenschubführung, so erfolgt gleichzeitig eine Halterung des Betätigungsschiebers an der Gehäusewand.For guidance purposes, the actuating slide can be displaceably guided on the outer wall of the housing by means of a sliding guide. If the slide guide is a prism slide guide, the actuating slide is held on the housing wall at the same time.

In einer einfachen Ausbildung kann dabei der Betätigungsschieber einen T-förmigen Führungsansatz aufweisen, der in eine sich in Erstreckungsrichtung der Gehäusewand erstreckende, in der Gehäusewand ausgebildete ebenfalls T-förmige Führungsnut hineinragt, wobei der Querbalken des T des Führungsansatzes in den Querbalken des T der Führungsnut eingreift.In a simple embodiment, the actuating slide can have a T-shaped guide projection which projects into a T-shaped guide groove which extends in the direction of extension of the housing wall and is also formed in the housing wall, the crossbar of the T of the guide projection projecting into the crossbar of the T of the guide groove intervenes.

Zur Vermeidung von Schleifspuren an der Gehäuseaußenwand kann der Betätigungsschieber über Gleitstücke an seiner Bewegungsbahn an der Gehäuseaußenwand abgestützt sein. Dabei können in einfacher Weise die Gleitstücke in Ausnehmungen an der der Gehäuseaußenwand zugewandten Seite des Betätigungsschiebers von diesem um ein geringes Maß hervorstehend angeordnet sein.To avoid grinding marks on the outer wall of the housing, the actuating slide can be supported on its movement path on the outer wall of the housing by means of sliders. In this case, the sliders can be arranged in recesses on the side of the actuating slide facing the housing outer wall so that it protrudes by a small amount.

Um den Betätigungsschieber spielfrei gegenüber dem Uhrgehäuse anzuordnen und Klappergeräusche zu vermeiden, können die Gleitstücke federnd an der Gehäuseaußenwand in Anlage sein. Dies ist zum einen dadurch möglich, daß die Gleitstücke mittels einer am Betätigungsschieber abgestützten Druckfeder in Richtung zur Gehäuseaußenwand federbeaufschlagt sind. Eine andere Möglichkeit besteht darin, daß die Gleitstücke aus einem federelastischen Werkstoff bestehen.In order to arrange the actuating slide without play relative to the watch case and to avoid rattling noises, the sliders can be resiliently in contact with the outer wall of the case. This is possible on the one hand in that the sliders are spring-loaded in the direction of the outer wall of the housing by means of a compression spring supported on the actuating slide. Another Possibility is that the sliders are made of a resilient material.

Um ein Verdrehen des Betätigungsschiebers aus seiner Bewegungsbahnm zu vermeiden, kann der Betätigungsschieber in einer an der Gehäuseaußenwand ausgebildeten Führung bewegbar geführt sein.In order to prevent the actuating slide from rotating out of its movement path, the actuating slide can be guided movably in a guide formed on the outer wall of the housing.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it
Figure 1
a plan view of half of a housing ring of a watch in partial section,
Figure 2
a side view of the clock of Figure 1 in section along the line II-II.

Die in den Figuren dargestellte Armbanduhr ist eine Repetieruhr mit Minutenrepetition und einem Uhrgehäuse mit rundem Querschnitt.The wristwatch shown in the figures is a repeater watch with minute repeater and a watch case with a round cross section.

Das Uhrgehäuse besteht aus einem Gehäusering 1, dessen eine Öffnung durch ein Deckelteil 2 verschließbar ist, welches auch die mit einem Glas 3 verschlossene Sichtöffnung 4 aufweist.The watch housing consists of a housing ring 1, one opening of which can be closed by a cover part 2, which also has the viewing opening 4 closed by a glass 3.

Die andere Öffnung des Gehäuserings 1 ist durch ein Bodenteil 5 verschließbar.The other opening of the housing ring 1 can be closed by a base part 5.

Sowohl das Deckelteil 2 als auch das Bodenteil 5 sind mittels Schrauben mit dem Gehäusering 1 verbindbar, wobei durch einen Dichtring zwischen Gehäusering 1 und Deckelteil 2 bzw. Bodenteil 5 eine Abdichtung erfolgt.Both the cover part 2 and the base part 5 can be connected to the housing ring 1 by means of screws, a seal being provided by a sealing ring between the housing ring 1 and the cover part 2 or base part 5.

Sowohl das Deckelteil 2 als auch das Bodenteil 5 besitzen einen etwas größeren Außendurchmesser als der Gehäusering 1, so daß sich im zusammengebauten Zustand dieser drei Teile eine radial umlaufende Nut an der Außenwand des Uhrgehäuses ergibt, die eine Führung 6 für einen Betätigungsschieber 7 bildet.Both the cover part 2 and the bottom part 5 have a slightly larger outer diameter than the housing ring 1, so that in the assembled state of these three parts there is a radially circumferential groove on the outer wall of the watch case, which forms a guide 6 for an actuating slide 7.

Der Betätigungsschieber 7 weist einen radial nach außen hervorstehenden Betätigungsnocken 8 auf und ist in der Führung 6 um ein bestimmtes Maß verschiebbar. An der der Gehäuseaußenwand 9 des Gehäuserings 1 zugewandten Seite des Betätigungsschiebers 7 sind in diesem Ausnehmungen 10 ausgebildet, in denen Gleitstücke 11 eingesetzt sind, die um ein geringes Maß von dem Betätigungsschieber 7 hervorstehen und an dem Boden der Gehäuseaußenwand 9 anliegen. Die Gleitstücke 11 bestehen aus einem sowohl auf der Gehäuseaußenwand 9 gut gleitfähigen als auch federelastischen Werkstoff.The actuating slide 7 has a radially outwardly projecting actuating cam 8 and can be displaced by a certain amount in the guide 6. On the housing outer wall 9 of the housing ring 1 side of the actuating slide 7 are formed in this recesses 10, in which sliders 11 are used, which protrude from the actuating slide 7 to a small extent and bear against the bottom of the outer housing wall 9. The sliders 11 consist of a material which is easy to slide on the outer wall 9 of the housing and is also resilient.

Im Bereich, in dem der Betätigungsschieber 7 an der Gehäuseaußenwand 9 entlang verschiebbar ist, ist parallel zur Gehäuseaußenwand 9 im Uhrgehäuse eine im Querschnitt T-förmige Führungsnut 12 ausgebildet, deren Querbalken des T sich parallel zur Gehäuseaußenwand 9 erstreckt und deren Senkrechtbalken radial nach außen sich erstreckt und an der Gehäuseaußenwand 9 nach außen mündet.In the area in which the actuating slide 7 is displaceable along the outer wall 9 of the housing, a guide groove 12 with a T-shaped cross section is formed parallel to the outer wall 9 of the watch, the transverse bar of the T extending parallel to the outer wall 9 of the housing and the vertical bar extending radially outwards extends and opens to the outside of the housing outer wall 9.

Der Betätigungsschieber 7 weist einen ebenfalls T-förmigen Führungsansatz 13 auf, der etwa den gleichen Querschnitt wie die Führungsnut 12 besitzt, in die Führungsnut 12 hineinragt und in dieser verschiebbar geführt ist.The actuating slide 7 has a likewise T-shaped guide projection 13, which has approximately the same cross section as the guide groove 12, projects into the guide groove 12 and is displaceably guided therein.

Dadurch, daß eine Seitenwand der Führungsnut 12 durch den radial äußeren Bereich des Bodenteils 5 und der andere Teil der Führungsnut 12 in dem Gehäusering 1 ausgebildet ist, kann der Führungsansatz 13 bei von dem Gehäusering 1 abgenommenem Bodenteil 5 in die Führungsnut 12 eingesetzt und durch Befestigen des Bodenteils 5 an dem Gehäusering 1 in der Führungsnut 12 gehalten werden.Characterized in that a side wall of the guide groove 12 is formed by the radially outer region of the bottom part 5 and the other part of the guide groove 12 in the housing ring 1, the guide projection 13 can be inserted into the guide groove 12 when the bottom part 5 is removed from the housing ring 1 and secured by fastening of the bottom part 5 are held on the housing ring 1 in the guide groove 12.

Zum Gehäusering 1 hervorstehend und in eine entlang eines Teils der Peripherie des Gehäuserings 1 sich erstreckende Ausnehmung 14 ragend ist am Betätigungsschieber 7 ein Anschlag 15 angeordnet, der eine Ausnehmung 16 aufweist, in die ein Amboßblock 17 aus verschleißfestem und reibungsarmen Werkstoff eingesetzt ist.Protruding to the housing ring 1 and projecting into a recess 14 extending along part of the periphery of the housing ring 1, a stop 15 is arranged on the actuating slide 7, which has a recess 16 into which an anvil block 17 made of wear-resistant and low-friction material is inserted.

An der Anlagefläche 18 des Amboßblocks 17, die sich etwas radial zum Uhrgehäuse erstreckt, liegt die eine Stirnseite eines Betätigungsbolzens 19 an.One end face of an actuating bolt 19 lies against the contact surface 18 of the anvil block 17, which extends somewhat radially to the watch case.

Der Betätigungsbolzen 19 ragt in eine in die Ausnehmung 14 mündende Bohrung 20 größeren Durchmessers als des Durchmessers des Betätigungsbolzens 19, wobei die Bohrung 20 sich etwa tangential in der durch den Gehäusering 1 gebildeten Gehäusewand erstreckt und als Grundbohrung ausgebildet ist.The actuating bolt 19 protrudes into a bore 20 opening into the recess 14 of a larger diameter than the diameter of the actuating bolt 19, the bore 20 extending approximately tangentially in the housing wall formed by the housing ring 1 and being designed as a basic bore.

In der Nähe des Bodens 21 der Bohrung 20 verbindet eine radial nach innen gerichtete Montageöffnung 22 die Bohrung 20 mit dem Gehäuseinneren 23.In the vicinity of the bottom 21 of the bore 20, a radially inwardly directed mounting opening 22 connects the bore 20 to the interior 23 of the housing.

Im Bereich der Mündung der Bohrung 20 in die Ausnehmung 14 ist in die Bohrung 20 ein Führungsring 24 fest eingesetzt, der an seiner Innenwand eine radial umlaufende Ringnut 25 aufweist, in die ein den Betätigungsbolzen 19 undicht umschließender Dichtring 26 eingesetzt ist.In the area of the mouth of the bore 20 into the recess 14, a guide ring 24 is fixed in the bore 20 used, which has a radially circumferential annular groove 25 on its inner wall, in which a sealing ring 26 which surrounds the actuating bolt 19 is inserted.

Der Betätigungsbolzen 19 ist axial aufeinandersteckbar zweiteilig ausgebildet, wobei die aneinanderliegenden Bereiche der beiden Teile des Betätigungsbolzen 19 sich innerhalb der Bohrung 20 befinden.The actuating pin 19 is designed to be axially pluggable in two parts, the abutting regions of the two parts of the actuating pin 19 being located within the bore 20.

Eine mit ihrem einen Ende am Boden 21 der Bohrung 20 abgestützen Druckfeder 27 liegt mit ihrem anderen Ende an dem inneren Teil des Betätigungsbolzens 19 an und hält diesen in Anlage an dem nach außen ragenden Teil des Betätigungsbolzens 19 sowie beaufschlagt den gesamten Betätigungsbolzen 19 nach außen. Damit wird durch den an dem Amboßblock 17 anliegenden Betätigungsbolzen 19 auch der Betätigungsschieber 7 bis in seine durch einen Anschlag bestimmte Ruhestellung geschoben. Dieser Anschlag wird durch das eine Ende der Führungsnut 12 gebildet, an das der Führungsansatz 13 zur Anlage gelangt.A with its one end supported on the bottom 21 of the bore 20 compression spring 27 rests with its other end on the inner part of the actuating pin 19 and holds it in contact with the outwardly projecting part of the actuating pin 19 and acts on the entire actuating pin 19 to the outside. Thus, the actuating slide 7 is also pushed into its rest position determined by a stop by the actuating bolt 19 resting on the anvil block 17. This stop is formed by one end of the guide groove 12, against which the guide projection 13 comes to rest.

Durch Bewegung des Betätigungsschiebers 7 von Hand entgegen der Kraft der Druckfeder 27 ist der Betätigungsbolzen 19 in die Bohrung 20 hinein bewegbar.By moving the actuating slide 7 by hand against the force of the compression spring 27, the actuating pin 19 can be moved into the bore 20.

Dabei wird ein am Betätigungsbolzen 19 angeordneter, radial von diesem hervorstehender und durch einen Führungsschlitz 28 in das Gehäuseinnere 23 ragender Mitnehmer 29 etwa tangential an der Innenwand des Gehäuserings 1 entlang bewegt. Der Mitnehmer 29 ist dabei an einem Anschlagnocken 30 eines schwenkbar gelagerten Bauteils 31 eines nicht dargestellten Schalgwerks der Repetieruhr in Anlage, welches durch die Schwenkbewegung des Bauteils 31 aufgezogen wird.In this case, a driver 29, which is arranged on the actuating pin 19 and protrudes radially therefrom and projects through a guide slot 28 into the housing interior 23, is moved approximately tangentially along the inner wall of the housing ring 1. The driver 29 is on a stop cam 30 of a pivotally mounted component 31 of a scarf mechanism, not shown the repeater clock in system, which is wound up by the pivoting movement of component 31.

Der Führungsschlitz 28 verbindet die Bohrung 20 mit dem Gehäuseinneren 23 und erstreckt sich von dem Bereich des Führungsrings 24 bis zur Montageöffnung 22, in die er einmündet.The guide slot 28 connects the bore 20 to the housing interior 23 and extends from the region of the guide ring 24 to the mounting opening 22, into which it opens.

Der zur Oberseite des Gehäuseringes 1 hin offen ausgebildete Führungsschlitz 28 wird nach der Oberseite hin durch das Deckelteil 2 verschlossen.The guide slot 28, which is open towards the top of the housing ring 1, is closed towards the top by the cover part 2.
