Definitions
- the invention relates to a closure specified in the preamble of claim 1 type (such as, for US-A-6,367,296 known).
- the lock is attached to the flap or door while the closure member is seated on the body. It can act in the closed state on the flap or door a force in the opening direction. This can be done for example by elastic sealing means which are arranged between the flap or the door on the one hand and the body on the other. If the flap or door is opened, this force acting in the direction of opening drives the catch away from the closing part, resulting in disturbing noises. Because the flap or door acts as a sound box, such sounds are amplified.
- the invention has for its object to develop a closure which reduces the aforementioned noise when opening the door or door. This is inventively achieved by the measures mentioned in claim 1, which has the following special significance.
- Such an attenuator can be designed as a rotary damper according to claim 2, but also designed as a linear damper in the sense of claim 4. Such an attenuator could also be designed as an electromagnetic damper, as suggested in claim 5.
- the attenuator has a structure shown in FIG. 3 with a medium, this may be liquid or gaseous, as in claim 6 is called.
- a liquid medium as claimed in claim 7, use a viscous liquid.
- a gaseous medium it is recommended according to claim 8, to use air as a medium.
- Fig. 1 and 2 of the lock housing 10 only the lower part is shown, while the upper part is removed, to provide an insight into the lock interior.
- the lock is fastened with its housing 10 in the present case to a flap of a vehicle.
- a closing part 11 which cooperates with a rotary latch 20 in the lock housing 10 when closing and opening the flap.
- the closing part 11 consists in the present case of a bracket attached to the body, of which in Figs. 1 and 3, only the closing effective strap web is shown in cross section.
- the rotary latch 20 has a recess 22 which receives the closing part 11 when closing the flap.
- the rotary latch 20 has in the present case, two notches, which are generated by peripheral cutouts, namely a pre-catch 23 and a main catch 24. From a pivot bearing 31 in the housing sits a pawl 30 which has a blocking point 32nd having. When the flap is fully closed, the pawl locking point 32 engages behind the rotary latch main catch 24. Then the closing part 11 is maximally moved into a cutout 12 from the lock housing 10 and the rotary latch 20 is in the "closed position" indicated by the auxiliary line 20.1.
- the attenuator 40 basically has the following, from Fig. 2 apparent inner structure.
- the damping member 40 initially comprises a receiving part 41, which receives numerous further parts 42 to 45.
- the receiving part 41 also has a housing function because it serves to attach the damping member 40 to the upper part of the lock housing 10, not shown in detail.
- the receiving part 41 has two holes 46, which are traversed in the installation of fastening screws 13, which are anchored in the housing upper part.
- the accommodated in the receiving part 41 parts of the damping member 40 are an input part 42, a moving part 43 which is in contact with a viscous medium 44 and a clutch 45, which is arranged between the input part 42 and the moving part 43.
- Such an attenuator could also be translationally effective and e.g. consist of a piston-cylinder arrangement, but the following rotary structure is provided in the present case.
- the moving part here consists of a rotor which engages in a hollow cylinder of the receiving part 41.
- the rotor 43 and the hollow cylinder 47 have mutually complementary annular grooves and annular lands, which engage with each other and create a gap between them for receiving the viscous medium 44.
- the rotor 43 has a further, pointing to a cover part 48 annular groove 14 and a bearing hole 15 for an inner pin of the input shaft 42 formed as input part.
- the input shaft 42 has a widened inner head, too is stocked in the cover 48.
- the hollow cylinder 47 is closed by the receiving part 11 by a ring seal 48.
- the clutch 45 consists of a coil spring whose turns engage in the annular groove 14 from the rotor 43 and there surrounds the peripheral surface of a arranged in the annular groove 14, rotatably connected to the rotor 43 coupling ring.
- the outer end of the coil spring 45 is bent in the axial direction and rotatably connected to the input part 42.
- the input part which consists here of an input shaft 42, is movably connected to the gear 50.
- the structure of the attenuator may be formed in various ways.
- the transmission could also consist of gears that mesh with each other.
- This gear 50 consists in the present case of a lever 51 which is provided with a slotted guide 52.
- a sliding block is arranged, which consists in the present case of a guide pin 53.
- the guide pin 53 is seated on the rotary latch 20 and engages in the slide guide 52 a.
- the lever 51 is rotatably mounted with a bearing head 54 on the input shaft 42, whereby the dot-dash line in Fig. 2 clarified rotor axis 17 at the same time the axis of rotation of the lever 51.
- the latch 30 must be moved away from its in Fig. 1 illustrated by the auxiliary line 30.1 blocking position in the sense of the rotary arrow 33 until its blocking point 22, the main catch 24 and thus the pre-catch 23 has released.
- This pawl rotation 33 can be triggered manually and / or by motor.
- the elastic sealing means mentioned at the beginning then provide, via the interaction between the closing part 11 and the rotary latch recess 22, that the rotary latch 20 executes a swiveling movement acting in the direction of opening according to pivoting arrow 25 of FIG.
- the shortest arm length 55.1 of the lever 51 acts between the attenuator 40 and the rotary latch 20, results in this first Aufschwenkphase a particularly large, acting on the rotary latch 20 damping effect.
- This is also very desirable because in the closed position 20.1 the elastic damping means are maximally deformed and therefore exert the greatest opening force. As a result, the aforementioned unwanted opening noise of the closure is at least greatly reduced, if not completely eliminated.
- the pivotal latch 20 is pivoted relatively slowly in the direction of the arrow 25.
- FIG. 3 the opening state of the closure is shown in FIG.
- the rotary latch 20 is in an illustrated by the auxiliary line 20.2 open position, which is determined by a stationary stop 19.
- the closing part 11 is completely extended out of the rotary latch recess 22 and has left a cutout 12 in the housing 10.
- the tailgate is open. Because the pawl 30 is under the action of an illustrated by a force arrow restoring force 34, it is supported with its locking point 22 freely on a peripheral region of the rotary latch 20 from.
- the pawl 30 is then located in a ready position illustrated by the auxiliary line 30.2 in FIG. 3.

Description
Die Erfindung bezieht sich auf einen Verschluss der im Oberbegriff des Anspruches 1 angegebenen Art (wie z.B. aus
Der Erfindung liegt die Aufgabe zugrunde, einen Verschluss zu entwickeln, der das vorgenannte Geräusch beim Öffnen der Klappe bzw. Tür reduziert. Dies wird erfindungsgemäß durch die im Anspruch 1 genannten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object to develop a closure which reduces the aforementioned noise when opening the door or door. This is inventively achieved by the measures mentioned in claim 1, which has the following special significance.
Durch das einseitig wirkende Dämpfungsglied zwischen der Drehfalle und dem Schlossgehäuse wird nur die Öffnungsbewegung der Drehfalle verlangsamt, während die Schließbewegung nicht beeinträchtigt wird. Man kann ein solches Dämpfungsglied als Rotationsdämpfer gemäß Anspruch 2 ausbilden, aber auch als Lineardämpfer im Sinne des Anspruches 4 gestalten. Ein solches Dämpfungsglied könnte auch als elektromagnetischer Dämpfer ausgebildet sein, wie es Anspruch 5 vorschlägt.By the single-acting damping member between the catch and the lock housing only the opening movement of the rotary latch is slowed down, while the closing movement is not affected. Such an attenuator can be designed as a rotary damper according to claim 2, but also designed as a linear damper in the sense of claim 4. Such an attenuator could also be designed as an electromagnetic damper, as suggested in claim 5.
Sofern das Dämpfungsglied einen aus Fig. 3 ersichtlichen Aufbau mit einem Medium aufweist, kann dieses flüssig oder gasförmig ausgebildet sein, wie in Anspruch 6 genannt ist. Bei einem flüssigen Medium wird man, wie Anspruch 7 vorschlägt, eine viskose Flüssigkeit nutzen. Bei einem gasförmigen Medium ist es gemäß Anspruch 8 empfehlenswert, Luft als Medium zu nutzen.If the attenuator has a structure shown in FIG. 3 with a medium, this may be liquid or gaseous, as in claim 6 is called. In a liquid medium, as claimed in claim 7, use a viscous liquid. In a gaseous medium, it is recommended according to claim 8, to use air as a medium.

In Fig. 1 und 2 ist vom Schlossgehäuse 10 lediglich der Unterteil gezeigt, während der Oberteil entfernt ist, um einen Einblick ins Schlossinnere zu gewähren. Das Schloss ist mit seinem Gehäuse 10 im vorliegenden Fall an einer Klappe eines Fahrzeugs befestigt. An einer dem Schloss zugeordneten Stelle an der nicht näher gezeigten Karosserie des Fahrzeugs sitzt ein Schließteil 11, der beim Schließen und Öffnen der Klappe mit einer Drehfalle 20 im Schlossgehäuse 10 zusammenwirkt. Der Schließteil 11 besteht im vorliegenden Fall aus einem an der Karosserie befestigten Bügel, von dem in den Fig. 1 und 3 lediglich der schließwirksame Bügelsteg im Querschnitt gezeigt ist. Die Drehfalle 20 hat eine Aussparung 22, die beim Schließen der Klappe den Schließteil 11 aufnimmt.In Fig. 1 and 2 of the
Die Drehfalle 20 besitzt im vorliegenden Fall zwei Rasten, die durch Umfangsausschnitte erzeugt sind, nämlich eine Vorrast 23 und eine Hauptrast 24. Aus einem Drehlager 31 im Gehäuse sitzt eine Klinke 30, die eine Sperrstelle 32 aufweist. Wenn die Klappe voll geschlossen ist, hintergreift die Klinken-Sperrstelle 32 die Drehfallen-Hauptrast 24. Dann ist der Schließteil 11 maximal in einen Ausschnitt 12 vom Schlossgehäuse 10 eingefahren und die Drehfalle 20 befindet sich in der durch die Hilfslinie 20.1 gekennzeichneten "Schließstellung".The
Baueinheitlich verbunden mit dem Schlossgehäuse 10 ist ein Dämpfungsglied 40. und ein dem Dämpfungsglied 40 nachgeschaltetes Getriebe 50. Im vorliegenden Fall ist das Dämpfungsglied 40 am Schlossgehäuse 10 befestigt, während das Getriebe 50 mit der Drehfalle 20 in Verbindung steht. Das Dämpfungsglied 40 hat grundsätzlich folgenden, aus Fig. 2 ersichtlichen inneren Aufbau.Structurally connected to the
Wie Fig. 2 verdeutlicht, umfasst das Dämpfungsglied 40 zunächst einen Aufnahmeteil 41, der zahlreiche weitere Teile 42 bis 45 aufnimmt. Der Aufnahmeteil 41 hat auch eine Gehäusefunktion, weil er zur Befestigung des Dämpfungsglieds 40 an dem nicht näher gezeigten Oberteil des Schlossgehäuses 10 dient. Dazu hat der Aufnahmeteil 41 zwei Bohrungen 46, die im Montagefall von Befestigungsschrauben 13 durchsetzt werden, die im Gehäuse-Oberteil verankert sind.As FIG. 2 illustrates, the
Die im Aufnahmeteil 41 aufgenommenen Teile des Dämpfungsglieds 40 sind ein Eingangsteil 42, ein Bewegungsteil 43, der in Kontakt mit einem viskosen Medium 44 steht und eine Schaltkupplung 45, die zwischen dem Eingangsteil 42 und dem Bewegungsteil 43 angeordnet ist. Ein solches Dämpfungsglied könnte auch translatorisch wirksam sein und z.B. aus einer Kolben-Zylinder-Anordnung bestehen, doch ist im vorliegenden Fall folgender rotativer Aufbau vorgesehen.The accommodated in the receiving
Der Bewegungsteil besteht hier aus einem Rotor, der in einem Hohlzylinder des Aufnahmeteils 41 eingreift. Der Rotor 43 und der Hohlzylinder 47 besitzen zueinander komplementäre Ringnuten und Ringstege, die ineinander greifen und zwischen sich einen Spalt zur Aufnahme des viskosen Mediums 44 erzeugen. Der Rotor 43 besitzt eine weitere, zu einem Deckteil 48 weisende Ringnut 14 und ein Lagerloch 15 für einen inneren Zapfen des als Eingangswelle 42 ausgebildeten Eingangsteils. Die Eingangswelle 42 hat einen verbreiterten inneren Kopf, der auch im Deckteil 48 lagernd geführt ist. Zur Absperrung des viskosen Mediums 44 ist der Hohlzylinder 47 vom Aufnahmeteil 11 durch eine Ringdichtung 48 verschlossen.The moving part here consists of a rotor which engages in a hollow cylinder of the
Im vorliegenden Fall besteht die Schaltkupplung 45 aus einer Wendelfeder, deren Windungen in der Ringnut 14 vom Rotor 43 eingreifen und dort die Umfangsfläche eines in der Ringnut 14 angeordneten, drehfest mit dem Rotor 43 verbundenen Kuppelrings umschließt. Das äußere Ende der Wendelfeder 45 ist in axialer Richtung abgebogen und drehfest mit dem Eingangsteil 42 verbunden. Der Eingangsteil, der hier aus einer Eingangswelle 42 besteht, ist mit dem Getriebe 50 mitbeweglich verbunden.In the present case, the
Der Aufbau des Dämpfungsglieds kann in verschiedener Weise ausgebildet sein. So ist es möglich, die in Fig. 1 mit 17 gekennzeichnete Achse des Rotors 43, im Gegensatz zum Ausführungsbeispiel, koaxial mit der bereits beschriebenen Schwenkachse 21 der Drehfalle 20 anzuordnen. Dann könnte das Getriebe auch aus Zahnrädern bestehen, die miteinander in Eingriff stehen. Vorteilhaft ist es aber, wie das Ausführungsbeispiel zeigt, die Rotorachse 17 gegenüber der Schwenkachse 21 der Drehfalle 20 seitlich versetzt anzuordnen und diesen Versatz zwischen Rotor 43 und Drehfalle 20 durch das Getriebe 50 zu überbrücken.The structure of the attenuator may be formed in various ways. Thus, it is possible, in contrast to the exemplary embodiment, to arrange the axis of the
Dieses Getriebe 50 besteht im vorliegenden Fall aus einem Hebel 51, der mit einer KulissenfĂĽhrung 52 versehen ist. In der KulissenfĂĽhrung 52 ist ein Kulissenstein angeordnet, der im vorliegenden Fall aus einem FĂĽhrungsstift 53 besteht. Der FĂĽhrungsstift 53 sitzt an der Drehfalle 20 und greift in die KulissenfĂĽhrung 52 ein. Wie aus Fig. 2 hervorgeht, ist der Hebel 51 mit einem Lagerkopf 54 auf der Eingangswelle 42 drehfest gelagert, wodurch die strichpunktiert in Fig. 2 verdeutlichte Rotorachse 17 zugleich die Drehachse des Hebels 51 ist.This
In der Schließstellung 20.1 der Drehfalle 20 von Fig. 1 befindet sich der Führungsstift 53 am Innenende der Kulissenführung 52, wodurch sich eine verhältnismäßig kleine wirksame Armlänge 55.1 am Hebel 51 ergibt. Geht man davon aus, dass die im Dämpfungsglied 40 erzeugte Dämpfungswirkung im wesentlichen unabhängig von der Drehstellung des Rotors 43 ist, so ist in dieser Schließstellung 20.1 wegen der kurzen Armlänge 55.1 die auf die Falle 20 wirkende Dämpfung am größten.In the closed position 20.1 of the
Will man die geschlossene Heckklappe des Fahrzeugs öffnen, so muss die Klinke 30 aus ihrer in Fig. 1 durch die Hilfslinie 30.1 verdeutlichten Sperrstellung im Sinne des Drehpfeils 33 wegbewegt werden, bis ihre Sperrstelle 22 die Hauptrast 24 und damit auch die Vorrast 23 freigegeben hat. Diese Klinkendrehung 33 kann manuell und/oder motorisch ausgelöst werden. Die eingangs erwähnten elastischen Dichtungsmittel sorgen dann über die Wechselwirkung zwischen dem Schließteil 11 und der Drehfallen-Aussparung 22, dass die Drehfalle 20 eine im Öffnungssinne wirkende Schwenkbewegung gemäß Schwenkpfeil 25 von Fig. 1 ausführt. Weil dabei, wie gesagt, die kürzeste Armlänge 55.1 des Hebels 51 zwischen dem Dämpfungsglied 40 und der Drehfalle 20 wirkt, ergibt sich in dieser ersten Aufschwenkphase eine besonders große, auf die Drehfalle 20 wirkende Dämpfungswirkung. Das ist auch sehr erwünscht, weil in der Schließstellung 20.1 die elastischen Dämpfungsmittel maximal deformiert sind und daher die größte Öffnungskraft ausüben. Dadurch wird das eingangs erwähnte unerwünschte Öffnungsgeräusch des Verschlusses mindestens stark herabgesetzt, wenn nicht gar vollkommen beseitigt. Trotz der hohen auf sie wirkenden Kräfte, wird die Schwenkfalle 20 verhältnismäßig langsam im Sinne des Pfeils 25 aufgeschwenkt.If you want to open the closed tailgate of the vehicle, so the
Das ändert sich im Vollzug der weiteren Aufschwenkbewegung 25 der Drehfalle 20. Wie bereits erwähnt wurde, ist in Fig. 3 der Öffnungszustand des Verschlusses gezeigt. Die Drehfalle 20 befindet sich in einer durch die Hilfslinie 20.2 veranschaulichten Offenstellung, die durch einen ortsfesten Anschlag 19 bestimmt ist. In der Offenstellung 20.2 ist der Schließteil 11 aus der Drehfallen-Aussparung 22 ganz ausgefahren und hat einen Ausschnitt 12 im Gehäuse 10 verlassen. Die Heckklappe ist offen. Weil die Klinke 30 unter der Wirkung einer durch einen Kraftpfeil verdeutlichten Rückstellkraft 34 steht, stützt sie sich mit ihrer Sperrstelle 22 frei an einem Umfangsbereich der Drehfalle 20 ab. Die Klinke 30 befindet sich dann in einer durch die Hilfslinie 30.2 in Fig. 3 verdeutlichten Bereitschaftsstellung.This changes in the course of the
Wird die Heckklappe des Fahrzeugs zugeklappt und dadurch der Schließteil im Sinne des Pfeils 18 von Fig. 3 gegen die Drehfalle 20 bewegt, so erfolgt ein Rückschwenken 26 der Drehfalle 20, bis die Klinken-Sperrstelle 32 wieder in die erwähnte Vorrast 23 bzw. Hauptrast 24 der Drehfalle 20 einschnappt. Bei diesem Rückschwenken 26 wird natürlich der Hebel 51 mitgedreht, doch übt dann wegen der Schaltkupplung 45 das Dämpfungsglied 40 keine oder nur eine geringe Dämpfungswirkung auf die Drehfalle 20 aus. Ursache dafür ist Folgendes.If the tailgate of the vehicle is closed and thereby moves the closing part in the direction of the
Die vorerwähnte Schaltwirkung der Wendelfeder 45 ergibt sich aufgrund ihres definierten Windungsverlaufs. Wegen der geschilderten Kopplung über den Hebel 51 wirken sich die Auf- bzw. Zuschwenkbewegungen 25, 26 der Drehfalle 20 im gleichen Sinne auf den Rotor 43 des Dämpfungsglieds 40 aus. Deshalb sind sie auch in Fig. 2 eingezeichnet. Beim Aufschwenken im Sinne des Pfeils 25 dreht sich die Wendelfeder 25 mit ihren Windungen um den Kupplungsring 16 zu und nimmt dadurch den Rotor 43 mit. Beim Aufschwenken 25 der Drehfalle 20 im Öffnungssinne 26 gemäß Fig. 1 liegt daher eine Kupplung zwischen dem Hebel 51 und dem Rotor 43 vor. Die Drehfalle 20 wird in ihrer Aufschwenkbewegung 25 gedämpft.The aforementioned switching action of the
Umgekehrt, beim Zuschwenken 26 im Schließsinne, wird zwar die Wendelfeder 45 wegen ihrer drehfesten Verbindung mit der Eingangswelle 42 von Fig. 2 mitgenommen, doch wegen dieser Drehung im Gegensinne öffnet sich die Wendel, weshalb der Kupplungsring 16 praktisch ohne Widerstand an der Umfangsfläche des Kupplungsrings 16 frei gleiten kann. Der Rotor 43 bleibt dabei praktisch in Ruhe. Dadurch ergibt sich keine Dämpfung. Der Rotor 43 ist von der Rückbewegung des Hebels 51 entkuppelt. Die Schließbewegung 26 der Drehfalle 20 gemäß Fig. 3 läuft dann praktisch ohne Hemmung durch das Dämpfungsglied 40 ab.Conversely, when swiveling 26 in the closing direction, although the
Wie ein Vergleich von Fig. 1 und 3 zeigt, ändert sich die wirksame Armlänge im Zuge der Aufschwenkbewegung der Drehfalle 20 beträchtlich. In der Offenstellung 20.2 von Fig. 3 hat die wirksame Armlänge ihren maximalen Wert 55.2 erreicht. Der Führungsstift 53 befindet sich im äußeren Bereich der Kulissenführung 52. Weil die Armlänge im Zuge der Aufschwenkbewegung 25 anwächst, nimmt die auf die Drehfalle 20 wirkende Dämpfung immer mehr ab. Das ist durchaus erwünscht, weil im Zuge der Aufschwenkbewegung 25 die elastischen Dichtungsmittel zwischen der Klappe und der Karosserie sich entspannt haben und daher eine zunehmend geringere Kraft in Öffnungsrichtung ausüben. Die Erfindung ermöglicht so eine abgestimmte. Dosierung der Dämpfung der Drehfalle 20.As a comparison of Fig. 1 and 3 shows, the effective arm length changes in the course of Aufschwenkbewegung the

a damping element (40) with a damping action at one end is positioned between the rotary lock (20) and the lock housing (10), thus slowing down the opening movement of the rotary lock (20). - Closure according to Claim 1, characterised in that in the closed condition the tailgate or door exerts a force in the opening direction.
- Closure according to Claim 2, characterised in that the force acting in the opening direction is generated by a resilient sealing medium that is arranged between the tailgate or door one hand and the body on the other hand.
- Closure according to Claim 2, characterised in that the force acting in the opening direction is generated by a spring.
- Closure according to Claim 2, characterised in that the force acting in the opening direction is generated by a drive.
- Closure according to one of Claims 1 to 5, characterised in that the damping element (40) is a rotational damper.
- Closure according to Claim 6, characterised in that the damping element (40) has a retaining part (41) that holds other parts of the damping element (40), i.e.
an input part (42), a moving part (43), a medium (44) in contact with the moving part (43) and
a switching coupling (45) that between the input part (42) is coupled with the moving part (43) when the rotary latch swings open (25) in the opening direction and decoupled when it swings closed (26) in the closing direction,
and that the retaining part (41) of the damping element (40) is connected to the lock housing (10) or the rotary lock (20), whereas the input part (42) is in connection with the rotary lock (20) or with the lock housing (10). - Closure according to one of Claims 1 to 5, characterised in that the damping element (40) is a linear damper
- Closure according to one of Claims 1 to 5, characterised in that the damping element (40) is an electromagnetic damper
- Closure according to one of Claims 1 to 9, characterised in that the effect of the damping element (40) is achieved by a liquid or gaseous medium (44).
- Closure according to Claim 10, characterised in that the liquid medium (44) is a viscous liquid, especially silicone oil or silicone grease.
- Closure according to Claim 10, characterised in that the gaseous medium (44) is air.
- Closure according to one of Claims 1 to 12, characterised in that a gear unit (50) is arranged between the damping element (40) and the rotary lock (20).
- Closure according to Claim 13, characterised in that the damping exerted by means of the gear unit (50) on the swivelling movement (25) of the rotary lock (20) in the area of the closed position (20.1) of the rotary lock (20) is embodied differently than in the area of the open position (20.2).
- Closure according to Claim 14, characterised in that the damping acting on the swivelling movement (25) of the rotary lock (20) is greatest in the area of the closed position (20.1) of the rotary lock (20) and reduces during the further swivelling in the direction of the open position (20.2).
- Closure according to Claim 12, 13 or 14, characterised in that the gear unit consists of meshed toothed wheels.
- Closure according to Claims 12, 13, or 14, characterised in that the gear unit (50) consists of a lever (51) the effective arm length (55.1, 55.2) of which can be changed.
- Closure according to Claim 17, characterised in that the effective arm length (55.1, 55.2) of the lever can be changed relative to the swivelled position of the rotary lock (20),
with the lever (51) having the shortest effective arm length (55.1) in the closed position (20.1) of the rotary lock (20), that becomes increasingly longer (55.2) during the swivelling (25) to the open position (20.2) of the rotary lock (20). - Closure according to Claim 17 or 18, characterised in that the damping element (40) serves as a rotary bearing (17) for the lever
and that between the lever (51) and the rotary lock (20) a guide slot (52) and a guide pin (53) are arranged. - Closure according to Claim 19, characterised in that the guide slot (52) is arranged on the lever (51) and a guide pin (53) is arranged on the rotary lock (20).
