Description

Die vorliegende Erfindung betrifft eine Betätigungsvorrichtung für ein Schloss und insbesondere eine Betätigungsvorrichtung für ein Schloss einer Klappe oder Tür an einem Kraftfahrzeug.The present invention relates to an actuating device for a lock and more particularly to an actuating device for a lock of a flap or door on a motor vehicle.

Betätigungsvorrichtungen dienen der Betätigung eines Schlosses von einer Schließstellung in eine Öffnungsstellung und umgekehrt. Derartige Betätigungsvorrichtungen für Schlösser, insbesondere Betätigungsvorrichtungen für Kraftfahrzeugtürschlösser bzw. Kraftfahrzeugklappenschlösser sind in einer Vielzahl von Ausführungsformen bekannt. Den Ausführungsvarianten gemeinsam ist, dass ein Handhabungsteil mindestens einem karosseriefest gelagerten Betätigungselement zugeordnet ist. Bei Betätigen des Handhabungstells wird diese Bewegung durch ein oder mehrere Übertragungselemente auf ein mit dem Schloss wirkverbundenen Betätigungsglied übertragen.Actuators serve to actuate a lock from a closed position to an open position and vice versa. Such actuators for locks, in particular actuators for motor vehicle door locks or motor vehicle door locks are known in a variety of embodiments. Common to the embodiments is that a handling part is associated with at least one actuation element mounted on the vehicle body. Upon actuation of the handle, this movement is transmitted by one or more transmission elements to an operatively connected to the lock actuator.

Es sind dabei insbesondere Türgriffe bekannt, die an der Außenhaut der Fahrzeugtür befestigt sind, und die um eine im Wesentlichen zu der Außenhaut der Tür parallele Schwenkachse verschwenkbar gelagert sind. Hierzu sind an der Außenhaut der Tür zwei Lagerstellen vorgesehen, die zur Kompensation von Umwelteinflüssen als sogenannte Loslager ausgeführt sind. Eine derartige Lagerung beinflusst das Betätigungsgefühl beim Verschwenken des Handhabungsteils allerdings negativ, da es aufgrund des Lagerspiels zu einem Wackeln des Handhabungsteils kommen kann. Unter Klimaeinfluss kann es bei der verwendeten Lagerung weiterhin zu Funktionsstörungen des Handhabungsteils führen.In particular, door handles are known which are fastened to the outer skin of the vehicle door and which are mounted so as to be pivotable about a pivot axis which is substantially parallel to the outer skin of the door. For this purpose, two bearings are provided on the outer skin of the door, which are designed to compensate for environmental influences as so-called floating bearing. Such storage, however, negatively affects the operating feeling during pivoting of the handling part, since it can cause a wobble of the handling part due to the bearing clearance. Under the influence of the climate, it can continue to lead to malfunction of the handling part in the storage used.

Zur Übertragung des Betätigungshubs des Übertragungselements zum Schloss wird bei der bekannten Betätigungsvorrichtung als Betätigungsglied häufig ein Bowdenzug eingesetzt. Der Bowdenzug kompensiert dabei die Distanz von der Betätigungseinrichtung zu dem Schloss. Insbesondere hat der Bowdenzug zusätzlich die Aufgabe ein ungewolltes Öffnen des Schlosses zu vermeiden. Dies wird durch eine Entkopplung des Bowdenzugs, bei Überschreiten einer vorbestimmten Belastung bei einem Crash, erzielt. Diese bekannte Betätigungseinrichtung weist an der Außenhaut zwei Durchbrüche auf, die jeweils abgedichtet werden müssen. Durchbrüche in der Außenhaut sind unter anderem aufgrund der steigenden Windgeräuschbelastung ungünstig, Nachteilig bei der bekannten Betätigungsvorrichtung ist zudem die Verwendung eines Bowdenzugs. Die Anordnung eines Bowdenzugs und dessen Entkopplung im Crash-Fall erfordert eine Vielzahl von weiteren Bauteilen. Insgesamt erfordert die bekannte Betätigungsvorrichtung eine kostenintensive Montage in mehreren Montageschritten.To transmit the operating stroke of the transmission element to the lock a Bowden cable is often used in the known actuator as the actuator. The Bowden cable compensates for the distance from the actuator to the lock. In particular, the Bowden cable additionally has the task of avoiding unintentional opening of the lock. This is achieved by a decoupling of the Bowden cable, when a predetermined load in a crash is exceeded. This known actuating device has on the outer skin on two openings, which must be sealed in each case. Breakthroughs in the outer skin are unfavorable, inter alia due to the increasing wind noise load, A disadvantage of the known actuator is also the use of a Bowden cable. The arrangement of a Bowden cable and its decoupling in the event of a crash requires a large number of other components. Overall, the known actuator requires a costly installation in several assembly steps.

Die Dokumente DE 673 625 C , EP 1 306 503 A1 , WO 2010/125556 A2 offenbaren eine Betätigungsvorrichtung für ein Schloss mit einem Handhabungsteil, einem Befestigungsteil und einem daran um eine erste Achse verschwenkbar angeschlagenen Übertragungselement. Das Handhabungsteil ist über eine Steck- oder Fügeverbindung an dem Übertragungselement angebracht.The documents DE 673 625 C . EP 1 306 503 A1 . WO 2010/125556 A2 disclose an actuating device for a lock with a handling part, a fastening part and a transmission element pivotably attached thereto about a first axis. The handling part is attached via a plug or joint connection to the transmission element.

Aufgabe der vorliegenden Erfindung ist es daher unter einem ersten Aspekt, eine Betätigungsvorrichtung für ein Schloss bereit zu stellen, die möglichst wenige Durchbrüche zur Montage benötigt.Object of the present invention is therefore to provide under a first aspect, an actuator for a lock that requires as few openings for installation.

Aufgabe der vorliegenden Erfindung ist es unter einem zweiten Aspekt, eine Betätigungsvorrichtung für ein Schloss bereit zu stellen, bei der der Bedienkomfort sowohl über die gesamte Lebensdauer als auch bei wechselnden Klimaeinflüssen gewährleistet ist.Object of the present invention, it is in a second aspect to provide an actuator for a lock, in which the ease of use is ensured both over the entire life and in changing climatic conditions.

Aufgabe der vorliegenden Erfindung ist es daher unter einem dritten Aspekt, eine Betätigungsvorrichtung für ein Schloss bereit zu stellen, die eine kompakte Bauweise aufweist.The object of the present invention is therefore, in a third aspect, to provide an actuating device for a lock, which has a compact design.

Aufgabe der vorliegenden Erfindung ist es unter einem vierten Aspekt der Erfindung eine Tür mit Betätigungsvorrichtung und Schloss bereit zu stellen, die eine einfache Montage aufweist. Diese erfindungsgemäße Aufgabe wird unter dem ersten Aspekt dabei durch die im Anspruch 1 angegebenen Merkmale gelöst.Object of the present invention is to provide under a fourth aspect of the invention, a door with actuator and lock, which has a simple assembly. This object of the invention is achieved in the first aspect by the features specified in claim 1.

Durch die im Anspruch 1 angegebene Betätigungsvorrichtung ist in der Außenhaut nur ein Durchbruch bzw. eine Lagerstelle notwendig. Das Handhabungsteil ist über eine Füge- oder Steckverbindung an dem Übertragungselement angebracht. Aufgrund dieser direkten Anbindung ist das Kippspiel annähernd ausgeschlossen. Des Weiteren ist eine Verschiebbarkeit in der Türebene nicht mehr gegeben.Due to the specified in claim 1 actuator only a breakthrough or a bearing is necessary in the outer skin. The handling part is attached via a joint or plug connection to the transmission element. Because of this direct connection, the tilting game is almost impossible. Furthermore, a displacement in the door level is no longer given.

Gemäß einer Weiterbildung des Erfindungsgedankens ist vorgesehen, dass in dem Aufnahmeraum des zylindrischer oder kegeligen Rohransatzes ein Schließsystem aufgenommen ist. Hierdurch wird eine sehr kompakte Bauweise erreicht, und es kann auf ein zusätzliches Gehäuse für das Schließsystem verzichtet werden. Zudem entfällt der Aufwand für zusätzliche Lackierarbeiten. Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass Umlenkmittel vorgesehen sind, die eine Verschwenkbewegung des Übertragungselements in eine zumindest anteilig in Richtung der ersten Achse (A) verlaufende Linearbewegung umwandeln, wobei die Umlenkmittel weiterhin einen um eine gekippt zur ersten Achse (A) verlaufende zweite Achse (B) verschwenkbares Hebelelement und ein daran anhängendes Schub- oder Zugmittel umfassen. Vorzugsweise sind zwischen dem Hebelarm und dem Übertragungselement miteinander kämmende Winkelzahnradabschnitte angeordnet. Durch diese kompakte Übertragung der Schwenkbewegung des Handhabungsteils auf das Schub- oder Zugmittel ist der Bauraumbedarf, der Materialbedarf und somit das Gesamtgewicht sehr gering. Ein eventuell notwendiger Massenausgleich über ein Gegengewicht, wie es In einer weiteren Ausgestaltung der Erfindung vorgesehen ist, kann mit einem erheblich verringerten Gewicht realisiert werden. Die statische Crash-Sicherheft wird wesentlich erhöht.According to one development of the inventive concept, it is provided that a closing system is accommodated in the receiving space of the cylindrical or conical pipe socket. As a result, a very compact design is achieved, and it can be dispensed with an additional housing for the locking system. In addition, eliminates the cost of additional painting. According to a particularly preferred embodiment of the invention it is provided that deflection means are provided which convert a pivoting movement of the transmission element into an at least partially in the direction of the first axis (A) extending linear motion, wherein the deflection means further comprise a pivotable about a tilted to the first axis (A) extending second axis (B) lever element and a pusher or traction means attached thereto. Preferably, intermeshing Winkelzahnradabschnitte are arranged between the lever arm and the transmission element. This compact transmission of the pivoting movement of the handling part on the push or pull means the space requirement, the material requirements and thus the total weight is very low. A possibly necessary mass balance over a counterweight, as provided in a further embodiment of the invention can be realized with a significantly reduced weight. The static crash security is significantly increased.

Weiterhin wird der Bedienkomfort für den Benutzer erhöht. Durch die Anordnung der festen Lagerstellen und der Umlenkmitteln, die über Winkelzahnradabschnitte in Wirkverbindung stehen ist die Reibung im Gesamtsystem gering. Hierdurch werden geringe Öffnungskräfte erzielt.Furthermore, the ease of use for the user is increased. Due to the arrangement of the fixed bearing points and the deflection means, which are about Winkelzahnradabschnitte in operative connection, the friction in the overall system is low. As a result, low opening forces are achieved.

Bei der Verwendung eines Flüsslgkeitsdämpfers, der an dem Hebelelement angeordnet ist, kann des Weiteren auf einen Massenausgleich komplett verzichtet werden. Hierdurch verringert sich das Gesamtgewicht der Betätigungsvorrichtung erheblich.When using a flüsslgigkeitssdämpfers, which is arranged on the lever element, further can be dispensed with a mass balance completely. This significantly reduces the total weight of the actuator.

Der Flüssigkeitsdämpfer umfasst in einer weiteren Ausgestaltung des Erfindungsgedankens eine Ventilregelung, wodurch zum einen im Crash-Fall eine Öffnung des Schlosses verhindert und zum anderen eine gedämpfte Rückstellung des Handhabungsteils erzielt wird.The fluid damper comprises in a further embodiment of the inventive concept, a valve control, whereby on the one hand in the event of a crash, an opening of the lock prevents and on the other a damped recovery of the handling part is achieved.

Die erfindungsgemäße Aufgabe wird unter dem vierten Aspekt dabei durch die im Anspruch 19 angegebenen Merkmale gelöst.The object of the invention is achieved in the fourth aspect by the features specified in claim 19.

Die Tür umfasst dabei eine Betätigungsvorrichtung gemäß Anspruch 17 und 18 sowie ein Schloss. Dabei sind sowohl die Betätigungsvorrichtung als auch das Schloss im Bereich des Umschlags der Seitenkante der Tür befestigt. Die Betätigungsvorrichtung bzw. das Befestigungsteil ist über mindestens einen Befestigungsabschnitt direkt an dem Schlossblech, an dem das Seitentürschloss angebracht ist, festgelegt. Eine Befestigung in einer Ebene die um etwa 90 Grad versetzt zur Außenhaut verläuft erleichtert die Montage. Zudem kann bei einer Crash-Außenhautverformung keine Relativbewegung der Betätigungsvorrichtung zu dem Schloss stattfinden. Dadurch kann auf einen entkoppelbaren Bowdenzug zur Verhinderung eines ungewollten Öffnens der Tür bzw. der Klappe verzichtet werden. Eine Festlegung der Betätigungsvorrichtung im Seitenbereich der Tür vermeidet zudem eine Befestigung an der crash-empfindlichen Außenhaut.The door comprises an actuator according to claim 17 and 18 and a lock. In this case, both the actuator and the lock in the area of the envelope of the side edge of the door are attached. The actuating device or the fastening part is fixed via at least one fastening portion directly to the lock plate, on which the side door lock is mounted. An attachment in a plane which is offset by about 90 degrees to the outer skin facilitates the assembly. In addition, no relative movement of the actuator to the castle can take place in a crash outer skin deformation. This can be dispensed with a decoupled Bowden cable to prevent accidental opening of the door or the door. A determination of the actuator in the side region of the door also avoids attachment to the crash-sensitive outer skin.

In die Befestigungsabschnitte können in einer noch weiteren Ausgestaltung des Erfindungsgedankens Gewindebuchsen integriert werden. Hierdurch werden eine optimale Positionierung und ein Ausgleich von Toleranzen beim Festlegen der Betätigungsvorrichtung In Bezug auf die Außenhaut möglich.In the fastening sections threaded bushings can be integrated in a still further embodiment of the inventive concept. As a result, an optimal positioning and compensation of tolerances in setting the actuator in relation to the outer skin possible.

Insgesamt ist eine sehr einfache und schnelle Montage der Betätigungsvorrichtung an der Außenhaut der Tür bzw. der Klappe möglich. Das Übertragungselement, die Umlenkmittel, sowie die Schub- oder Zugmittel können zu einer Einheit vormontiert werden. In einem abschließenden Montageschritt wird das Handhabungsteil ausgehend von der Außenseite der Außenhaut durch den Durchbruch in der Außenhaut auf die auf der Innenseite der Außenhaut angeordnete vormontierte Einheit bzw. auf das Überbagungsolement gefügt. Die Montage Öffnung d.h. der Durchbruch wird vorab durch eine von der Außenhaut-Innenseite eingesetzte umlaufende Dichtung gegen Windgeräusche abgedichtet.Overall, a very simple and quick installation of the actuator on the outer skin of the door or the flap is possible. The transmission element, the deflection means, as well as the push or pull means can be pre-assembled into a unit. In a final assembly step, the handling part is joined, starting from the outside of the outer skin through the opening in the outer skin, onto the preassembled unit arranged on the inner side of the outer skin or onto the Überbollungsolement. The mounting opening i. the breakthrough is sealed in advance by an inserted from the outer skin inside circumferential seal against wind noise.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Verfahrens ergeben sich aus den jeweiligen Unteransprüchen.Further advantageous embodiments and further developments of the method according to the invention will become apparent from the respective dependent claims.

For this purpose, the entire handling part 1 is connected via a transmission element 9 pivotally connected to a body-mounted mounting part 2 or socket. For attaching the actuating device for a lock on a door or flap of a motor vehicle, the fastening element 2 comprises two fastening sections, in the present case in each case a threaded sleeve 3, 4 is inserted. The threaded sleeves 3, 4 allow a screw connection to a correspondingly designed attachment point on the door or flap. These attachment parts are preferably located on the lock plate for connection of the side door lock, ie in a plane which extends approximately 90 degrees to the plane of the outer skin of the door.

Das Übertragungselement 9 ist um einen Bolzen 6 um eine erste Achse A verschwenkbar in dem Befestigungsteil 2 gehalten. Im eingebauten Zustand der dargestellten Betätigungsvorrichtung für ein Schloss wird die Achse A ungefähr senkrecht oder geringfügig zu dieser Richtung gekippt in geringem Abstand hinter der Außenhaut der Türe oder Klappe verlaufen.The transmission element 9 is held around a pin 6 pivotably about a first axis A in the fastening part 2. In the installed state of the illustrated actuator for a lock, the axis A is tilted approximately perpendicular or slightly to this direction at a small distance behind the outer skin of the door or flap.

Von dem Übertragungselement 9 ragt einseitig ein kurzer zylindrischer Rohransatz 91 ab. Dessen Außenfläche dient als Pass- und Fügefläche für eine Steckverbindung zu einem korrespondierenden Rohransatz 11, der ungefähr senkrecht zu dem Griffstück 12 an dem Handhabungsteil 1 absteht. Diese Steckverbindung ist durch einen aus korrespondierenden Ausnehmungen, Vorsprüngen 911 gebildeten Renk- oder Bajonettverschluss dauerhaft formschlüssig fixierbar. Dieser Renk- oder Bajonettverschluss ist zweckmäßig durch Rasthaken oder ähnliche Mittel gegen ein unbeabsichtigtes Lösen beim Gebrauch gesperrt. Alternativ oder zusätzlich können die genannten Teile auch durch eine Verklebung miteinander verbunden sein. Zweckmäßig verläuft die Achse C des zylindrischen Rohransatzes 91 an dem Obertragungselement 9 etwas beabstandet zu der Achse A des Bolzens 6. Dadurch ergibt sich beim Ziehen des Griffabschnitts 12 auf dessen gesamter Länge ein Abheben von der Außenhaut der Türe oder Klappe.From the transmission element 9 protrudes on one side from a short cylindrical pipe extension 91. Its outer surface serves as a fitting and joining surface for a plug connection to a corresponding pipe extension 11, which protrudes approximately perpendicular to the handle 12 on the handling part 1. This plug-in connection can be permanently positively locked by a recessed or bayonet lock formed from corresponding recesses, projections 911. This Renk- or bayonet lock is suitably locked by locking hooks or similar means against accidental loosening during use. Alternatively or additionally, the parts mentioned can also be connected to one another by gluing. Appropriately, the axis C of the cylindrical pipe extension 91 extends to the Obertragungselement 9 slightly spaced from the axis A of the bolt 6. This results in pulling the handle portion 12 over its entire length a lifting of the outer skin of the door or flap.

Da in einem typischen Türaufbau das Schloss unterhalb der Betätigungseinrichtung angeordnet ist, sieht die vorliegende Erfindung Umlenkmittel zur Erzeugung einer Bewegung in der Verbindungslinie zwischen Schloss und Betätigungseinrichtung vor. Diese Umlenkmittel sind vorliegend durch um einen Bolzen 16 um eine Achse B verschwenkbares Hebelelement 10 realisiert, das über einen Winkelzahnantrieb mit dem Übertragungselement 9 gekoppelt ist. Das Hebelelement 10 weist weiterhin einen hülsenförmigen Abschnitt 103 zur Lagerung des Bolzens 16 sowie einen um ungefähr 90 Grad versetzt angeordneten Hebelarm 104 auf. Damit das Hebelelement 10 die gewünschte Bewegung an seinem Endbereich 101 des Hebelarms 104 ausführt, muss die Achse B wie dargestellt gegenüber der gewünschten Bewegungsrichtung stark gekippt oder vorzugsweise nahezu senkrecht verlaufen. Aus Gründen des Benutzungskomforts wird die Achse A der Anbindung des Übertragungselements 9 im eingebauten Zustand ungefähr senkrecht zur Ausdehnung des Griffabschnitts 12 verlaufen. Dementsprechend schließen die Achsen A und B zweckmäßig einen Winkel von ungefähr 90 bis 120 Grad ein. Wegen des Winkelzahnantriebs ist es zudem vorteilhaft, wenn sich die Achsen A und B schneiden oder nur in geringem Abstand zueinander verlaufen.Since in a typical door assembly the lock is located below the actuator, the present invention provides deflection means for producing movement in the connection line between the lock and the actuator. In the present case, these deflecting means are realized by lever element 10 which can be pivoted about a pin 16 about an axis B and which is coupled to the transmission element 9 via an angle-toothed drive. The lever element 10 furthermore has a sleeve-shaped section 103 for mounting the bolt 16 and a lever arm 104 offset by approximately 90 degrees. In order for the lever element 10 to perform the desired movement on its end region 101 of the lever arm 104, the axis B must, as shown, be greatly tilted relative to the desired direction of movement or preferably run almost vertically. For reasons of ease of use, the axis A of the connection of the transmission element 9 in the installed state will be approximately perpendicular to the extension of the handle portion 12. Accordingly, the axes A and B suitably enclose an angle of approximately 90 to 120 degrees. Because of the angle gear drive, it is also advantageous if the axes A and B intersect or run only a small distance from each other.

Die Bewegung des Endbereichs 101 des Hebelarms 104 wird letztlich durch eine Schubstange 13 zu dem unterhalb der Betätigungsvorrichtung gelegenen Schloss übertragen. Hierzu ist der Endbereich der Schubstange in eine Aufnahmebohrung des Hebelarms 104 eingefügt und über ein Sicherungselement 14 fixiert. Die Übertragung der Bewegung des Hebelarms zu dem Schloss kann alternativ auch durch einen Seilzug erfolgen, der wegen der Sicherheit bei einer Deformation der Tür oder Klappe durch einen Aufprall in einer Hülle aufgenommen sein muss. Dadurch ergeben sich höherer Reibungswerte und eine undeutlicheres Betätigungsgefühl.The movement of the end portion 101 of the lever arm 104 is ultimately transmitted by a push rod 13 to the below the actuator lock. For this purpose, the end region of the push rod is inserted into a receiving bore of the lever arm 104 and fixed via a securing element 14. The transmission of the movement of the lever arm to the lock may alternatively be effected by a cable, which must be accommodated by a collision in a shell due to the security in a deformation of the door or flap. This results in higher friction values and a more indistinct operating feeling.

Damit die Betätigungsvorrichtung das Schloss nicht durch unbalancierte Massen im Fall eines Aufpralls des Fahrzeugs auf ein Hindernis oder eines Zusammenpralls mit einem anderen Fahrzeug auslöst, sieht die in Fig. 1 dargestellte Zusammenbau einen Flüssigkeitsdämpfer 7a mit einem besonderen Ventil als entsprechendes Kompensationsmittel vor. Das Ventil ist mit einer Testmasse ausgestattet, die durch die außergewöhnliche Beschleunigung gegen eine Feder bewegt wird und den Durchtritt des Dämpfungsmediums durch eine Reduzieröffnung einschränkt. Dadurch erhöht sich der Widerstand des Dämpfers gegen die durch die äußere Beschleunigung eventuell veranlasste Bewegung der Betätigungsvorrichtung.In order that the actuator does not trigger the lock by unbalanced masses in the event of a collision of the vehicle with an obstacle or a collision with another vehicle, see Fig. 1 shown assembly a liquid damper 7a with a special valve as a corresponding compensating means before. The valve is equipped with a test mass that is moved by the extraordinary acceleration against a spring and restricts the passage of the damping medium through a reducing port. This increases the resistance of the damper against the possibly caused by the external acceleration movement of the actuator.

Gemäß Fig. 2 kann anstelle des Flüssigkeitsdämpfers 7a auch ein geeignet angeordnetes Gegengewicht 7b die Sicherheit der Betätigungsvorrichtung bei einem Aufprall oder Anprall herstellen. Vorzugsweise wird das Gegengewicht 7b dazu an dem Hebelelement 10 gegenüber zu der Verzahnung 102 an einer Lasche 105 angeordnet. Je größer der Abstand des Gegengewichts 7b von der Achse B gewählt wird umso geringer kann die Masse ausreichen, um die außermittige Masse des Handhabungsteils 1 über die Kopplung durch den Winkelzahnantrieb 102, 92 auszugleichen.According to Fig. 2 For example, instead of the fluid damper 7a, a suitably arranged counterweight 7b can also ensure the safety of the actuating device in the event of an impact or impact. For this purpose, the counterweight 7b is preferably arranged on the lever element 10 opposite the toothing 102 on a tab 105. The greater the distance of the counterweight 7b from the axis B is chosen, the lower the mass can be sufficient to compensate for the off-center mass of the handling part 1 via the coupling by the angle gear drive 102, 92.

Wird das Handhabungsteil 1 von einem Benutzer an dem Griffabschnitt 12 in seine Öffnungsstellung nach außen gezogen, dann schenkt das Übertragungselement 9 in dem Befestigungsteil 2 um die Achse A. Durch diese Schwenkbewegung wälzen die Winkelzahnradabschnitte 92,102 des Winkelzahnantriebs aufeinander ab und das Hebelelement 10 dreht derart um die Achse B, dass der Endbereich 101 des Hebelarms 104 nach unten verschwenkt. Wie bereits obenstehend beschrieben wird diese Bewegung über die Schubstange 13 auf das Schloss übertragen. Die Rückstellung des Handhabungsteils 1 von der Öffnungsstellung in die Ausgangsstellung erfolgt selbsttätig. Hierzu ist eine Drehfeder 15 vorgesehen, die auf dem hülsenförmigen Abschnitt 103 des Hebelelements 10 aufgenommen ist. Die Drehfeder 15 stützt sich dabei einerseits an dem Hebelelement 10 und andererseits an dem Befestigungsteil 2 ab. Wird das Handhabungsteil 1 nach dem Öffnen losgelassen, wird das Handhabungsteil 1 über die vorgespannte Drehfeder 15 wieder in die Ausgangsstellung verschwenkt. Die Rückstellbewegung erfolgt hierbei gedämpft. Hierzu Ist ebenfalls der Flüssigkeitsdämpfer 7a vorgesehen, der bereits obenstehend beschrieben ist.If the handling part 1 is pulled outwards by a user on the handle portion 12 in its open position, then the transmission element 9 in the attachment part 2 about the axis A. By this pivoting movement, the Winkelzahnradabschnitte 92,102 of the angle gear drive from each other and the lever member 10 rotates in such a way the axis B that the end portion 101 of the lever arm 104 pivoted downward. As already described above, this movement is on the push rod 13 on the Castle transferred. The provision of the handling part 1 from the open position to the starting position takes place automatically. For this purpose, a torsion spring 15 is provided, which is received on the sleeve-shaped portion 103 of the lever member 10. The torsion spring 15 is supported, on the one hand, on the lever element 10 and, on the other hand, on the fastening part 2. If the handling part 1 is released after opening, the handling part 1 is pivoted back into the starting position via the pretensioned torsion spring 15. The return movement takes place here damped. For this purpose, the liquid damper 7a is also provided, which has already been described above.

In einer Ausführungsvariante ist vorgesehen, dass der Schließzylinder in dem zylindrischen Rohrabsatz aufgenommen Ist. Hierdurch entfällt ein weiteres Gehäuse für den Schließzylinder und es wird eine kompakte Bauweise erzielt.In one embodiment, it is provided that the lock cylinder is received in the cylindrical tube section. This eliminates a further housing for the lock cylinder and it is achieved a compact design.
