Description

Die vorliegende Erfindung betrifft ein Schloss für eine Ganzglastür, mit einem Schlossgehäuse, in dem eine Drückernuss um eine Betätigungsachse drehbar aufgenommen ist, und wobei ein Federelement vorgesehen ist, mit dem die Drückernuss in der Drehposition um die Betätigungsachse in eine Nulllage rückführbar ist, und wobei eine Verstelleinheit vorgesehen ist, mit der die Federvorspannung im Federelement verstellbar ist.The present invention relates to a lock for a glass door, comprising a lock housing, in which a follower is rotatably received about an actuating axis, and wherein a spring element is provided, with which the follower is in the rotational position about the actuating axis in a zero position traceable, and an adjusting unit is provided, with which the spring preload in the spring element is adjustable.

Aus der EP 1 049 845 B1 ist ein Schloss für eine Ganzglastür bekannt, das ein Schlossgehäuse aufweist, in dem eine Drückernuss drehbar aufgenommen ist. Zwischen dem Schlossgehäuse und einem Arm der Drückernuss ist eine Zugfeder vorgespannt angeordnet, und die Verbindung der Feder zum Schlossgehäuse weist eine Verstelleinheit auf. Die Verstelleinheit ermöglicht einen verstellbaren Federangriffspunkt zum Schlossgehäuse, und der Federangriffspunkt ist zwischen zwei Positionen verstellbar. Die Verstelleinheit ist durch einen verlagerbaren Stift gebildet, der zwischen zwei Positionen in einem Längsschlitz im Schlossboden und in der Schlossdecke verlagerbar ist. Die Ausrichtung des Längsschlitzes verläuft in Richtung des Armes der Drückernuss. Dabei ist der Längsschlitz derart ausgestaltet, dass der Stift durch einen bajonettartigen Verschluss in einer seiner beiden Endstellungen gehalten ist. Wird der Stift in der näher an der Drückernuss liegenden Position verrastet, weist die Federvorspannung einen geringen Wert auf, und wird der Stift in einem größeren Abstand zur Drückernuss verrastet, weist die Federvorspannung einen hohen Wert auf. Im Ergebnis sind zwei Werte der Federvorspannung voreinstellbar, und bei einer großen Federvorspannung ist die Kraft, mit der die Drückernuss in die Nulllage gedrückt wird, größer, als bei einer geringeren Federvorspannung. Die Nulllage der Drückernuss wird z.B. dann erreicht, wenn sich der Türdrücker in der Horizontalen erstreckt.From the EP 1 049 845 B1 For example, a lock for a glass door is known, which has a lock housing in which a follower is rotatably received. Between the lock housing and an arm of the follower a tension spring is arranged biased, and the connection of the spring to the lock housing has an adjustment. The adjustment allows an adjustable Federangriffspunkt the lock housing, and the spring application point is adjustable between two positions. The adjusting unit is formed by a displaceable pin which is displaceable between two positions in a longitudinal slot in the lock bottom and in the lock cover. The orientation of the longitudinal slot extends in the direction of the arm of the follower. In this case, the longitudinal slot is designed such that the pin is held by a bayonet-type closure in one of its two end positions. If the pin is locked in the position lying closer to the pusher, the spring preload has a low value, and if the pin is locked at a greater distance from the pusher, the spring preload has a high value. As a result, two values of the spring preload can be preset, and with a large spring preload, the force with which the pusher nut is in the zero position is pressed, larger than at a lower spring preload. The zero position of the follower is achieved, for example, when the door handle extends in the horizontal.

Nachteilhafterweise können lediglich zwei Werte der Federvorspannungen eingestellt werden, und es ist wünschenswert, die Federvorspannung stufenlos zwischen einem Minimalwert und einem Maximalwert zu verstellen. Ferner ist von Nachteil, dass zur Bedienung des Stiftes ein Werkzeug erforderlich ist, das in eine Schlitzgeometrie in den Schlitz eingesetzt werden muss. Um den Stift zwischen den beiden Positionen zu verstellen, muss das Werkzeug senkrecht auf die Planfläche des Schlossgehäuses aufgesetzt werden, so dass entweder ein Deckelelement erforderlich ist, das den Stift im Längsschlitz abdeckt und der Stift kann mit einem Werkzeug nur dann zwischen dem Minimalwert und dem Maximalwert verstellt werden, wenn ein Deckelelement vom Schlossgehäuse abgenommen wird.Disadvantageously, only two values of the spring preloads can be adjusted, and it is desirable to steplessly adjust the spring preload between a minimum value and a maximum value. Furthermore, it is disadvantageous that a tool is required to operate the pin, which must be inserted into a slot geometry in the slot. To adjust the pin between the two positions, the tool must be placed vertically on the flat surface of the lock housing, so that either a lid member is required, which covers the pin in the longitudinal slot and the pin can only with a tool between the minimum value and the Maximum value can be adjusted when a cover element is removed from the lock housing.

Schlosseinsatz für ein Glastürschloss mit einem eine von einem Gehäusedeckel verschlossenen Gehäuseschale aufweisenden Gehäuse, einer in der Gehäuseschale gegen die Rückstellkraft einer Fallenfeder verlagerbaren Falle, wobei die Falle einen Fallenkopf, der aus einer Fallenkopfdurchtrittsöffnung der Wandung des Gehäuses ragt, und einen Fallenschwanz, der fest mit dem Fallenkopf verbunden ist, der Angriffsschultern ausbildet zum Verlagern der Falle mittels eines Armes einer gegen die Rückstellkraft einer Drückernussfeder verdrehbaren Drückernuss und/oder eines Schließgliedes eines Schließzylinders, und an dem die am Gehäuse widergelagerte Fallenfeder angreift, aufweist. Zur gebrauchsvorteilhaften Weiterbildung, wird vorgeschlagen, dass die Fallenfeder von einer Wendelgangdruckfeder gebildet ist, die sich gegen eine Anlagefläche einer Fallenfeder-Einstellschraube abstützt.The EP 2 112 304 A2 discloses a lock or lock insert for a glass door lock with a housing closed by a housing cover housing having a displaceable in the housing shell against the restoring force of a latch spring case, the case a case head, which protrudes from a case head through opening of the wall of the housing, and a Fallen tail, which is fixedly connected to the case head, the attack shoulders forms for displacing the latch by means of an arm of a rotatable against the restoring force of a pusher nut pusher and / or a closing member of a lock cylinder, and on which engages against the housing latched spring has. For use-advantageous development, it is proposed that the latch spring is formed by a helical gear compression spring which is supported against a contact surface of a latch spring adjusting screw.

Aus der EP 1 477 625 A1 ist ein Ganzglastürschloss bekannt, das an einen Randbereich eines Ganzglasflügels auf dessen Seitenfläche ansetzbar ist, mit einer federbelasteten Falle und einer drehbar gelagerten Nuss, die ein Mehrkantloch zur Aufnahme der Drückerstange einer Türklinke aufweist und mit der Falle mittels einer verschiebbaren Fallenkulisse gekuppelt ist, und die von einer Feder in eine Ausgangsdrehstellung vorgespannt wird, die der Ausgangstellung der Türklinge entspricht, wobei an der Nuss ein Hebelarm ausgebildet ist, der in der Ausgangsdrehstellung der Nuss an einem Anschlag anliegt. Gemäß der Erfindung ist der Anschlag unter Verstellen der Ausgangsdrehstellung der Nuss und damit der Ausgangsdrehstellung der Türklinke verstellbar.From the EP 1 477 625 A1 a full glass door lock is known, which is attachable to an edge region of a glass pan on the side surface, with a spring-loaded latch and a rotatably mounted nut having a polygonal hole for receiving the pusher rod of a doorknob and is coupled to the case by means of a sliding latch slot, and the is biased by a spring in an initial rotational position corresponding to the starting position of the door blade, wherein on the nut, a lever arm is formed, which rests in the initial rotational position of the nut against a stop. According to the invention, the stop is adjustable by adjusting the output rotational position of the nut and thus the output rotational position of the doorknob.

Aus der DE 20 2009 002 001 U1 ist ein Schloss, insbesondere Einsteckschloss mit einer Drückernuss bekannt, die sich in einer Grundstellung mit einer Stützflanke an einem Exzenterkörper abstützt, der um eine Einstellachse gedreht werden kann, um die Drehstellung der Drückernuss in ihrer Grundstellung zu verändern.From the DE 20 2009 002 001 U1 is a lock, in particular mortise with a pusher known, which is supported in a basic position with a supporting edge on an eccentric body which can be rotated about a Einstellachse to change the rotational position of the follower in its normal position.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Schloss der vorbezeichneten Ausführung mit einer Verstelleinheit zu schaffen, die einfach ausgeführt und einfach bedienbar ist.It is therefore the object of the present invention to provide a lock of the aforementioned embodiment with an adjustment that is simple and easy to use.

Diese Aufgabe wird ausgehend von einem Schloss für eine Ganzglastür, gemäß dem Oberbegriff des Anspruches 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved starting from a lock for a glass door, according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt die technische Lehre ein, dass im Hebelarm ein Prallelement eingebracht ist, gegen das das Anschlagelement anschlägt.The invention includes the technical teaching that in the lever arm, a baffle element is introduced against which abuts the stop element.

Die Erfindung geht dabei von dem Gedanken aus, dass im Hebelarm ein Prallelement eingebracht ist, gegen das das Anschlagelement anschlägt.The invention is based on the idea that in the lever arm, a baffle element is introduced against which abuts the stop element.

Das Prallelement kann ein Material aufweisen, das vom Material des Hebelarms und folglich vom Material der Drückernuss abweicht. Beispielsweise kann das Prallelement aus einem Hartkunststoff gebildet sein, der in einer Aufnahme im Hebelarm eingesetzt wird. Damit wird der Vorteil erreicht, dass bei einem Anschlag des Hebelarms gegen das Anschlagelement eine Geräuschdämpfung erfolgt, und durch die Ausbildung des Prallelementes aus einem Hartkunststoff werden Deformationen in der Oberfläche des Prallelementes verhindert, insbesondere wenn der Türdrücker durch die Vorspannung des Federelementes gegen das Anschlagelement zurückschnellt.
Die Federvorspannung des Federelementes wird dadurch verstellt, dass das Schraubelement um eine Drehachse verdreht wird, wobei die Drehachse durch die Längsachse des Schraubelementes gebildet ist, und in Richtung zur Drückernuss verläuft. Das Schraubelement kann als Zylinderkopfschraube oder als Senkkopfschraube ausgeführt sein, und die Verbindung zwischen dem Schraubelement und dem Federelement erfolgt über den Gewindeschaft des Schraubelementes. Das Schraubelement ist dabei in einer festen Position, jedoch drehbar im Schlossgehäuse gelagert, und das dem Schraubelement zugewandte Ende des Federelementes kann bei Verdrehung des Schraubelementes entlang des Gewindeschaftes bewegt werden.
The baffle element may comprise a material which deviates from the material of the lever arm and consequently from the material of the pusher nut. For example, the impact element may be formed of a hard plastic, which is used in a receptacle in the lever arm. Thus, the advantage is achieved that in a stop of the lever arm against the stop element noise attenuation, and the formation of the baffle made of a hard plastic deformations in the surface of the baffle element are prevented, especially when the door handle snaps back by the bias of the spring element against the stop element ,
The spring bias of the spring element is adjusted by the fact that the screw is rotated about an axis of rotation, wherein the axis of rotation is formed by the longitudinal axis of the screw, and extends in the direction of the follower. The screw can be designed as a cylinder head screw or countersunk screw, and the connection between the screw and the spring element via the threaded shaft of the screw. The screw is in a fixed position, but rotatably mounted in the lock housing, and the screw element facing the end of the spring element can be moved upon rotation of the screw along the threaded shaft.

Mit besonderem Vorteil kann durch die erfindungsgemäße Ausführung der Verstelleinheit die Federvorspannung zwischen einem Minimalwert und einem Maximalwert stufenlos verstellt werden. Folglich ist die Federvorspannung nicht lediglich auf einen diskreten ersten und einen diskreten zweiten Wert einstellbar, sondern die Federvorspannung kann stufenlos auf jeden beliebigen Wert zwischen dem Minimalwert und dem Maximalwert verstellt werden. Insbesondere bei einem längeren Gebrauch des Schlosses kann sich die Nulllage der Drückernuss verstellen, und der Türdrücker, der in der Drückernuss aufgenommen ist, bewegt sich durch das Federelement nicht selbsttätig wieder in die Nulllage zurück. Um die selbsttätige Rückführung der Drückernuss und des Türdrückers zurück in die Nulllage zu ermöglichen, wenn ein Bediener den Türdrücker loslässt, kann das Schraubelement solange verstellt werden, bis die Federvorspannung einen Wert erreicht, der hinreichend ist, um die Drückernuss und den Türdrücker selbsttätig wieder in die Nulllage zurückzuführen. Im Ergebnis wird vermieden, dass eine unnötig hohe Federvorspannung eingestellt werden muss, und es wird eine Schwergängigkeit und Materialbelastung des Schlosses vermieden.With particular advantage, the spring preload between a minimum value and a maximum value can be adjusted continuously by the inventive design of the adjustment. Consequently, the spring bias is not adjustable to only a discrete first and a discrete second value, but the spring bias can be adjusted continuously to any value between the minimum value and the maximum value. In particular, in a prolonged use of the lock, the zero position of the follower can be adjusted, and the door handle, which is included in the follower, does not automatically move back to the zero position by the spring element. To the To allow automatic return of the follower and the door handle back to the zero position, when an operator releases the door handle, the screw can be adjusted until the spring preload reaches a value sufficient to automatically return the pusher and the door handle to the zero position due. As a result, it is avoided that an unnecessarily high spring preload must be set, and it is a binding and material loading of the castle avoided.

Die Verbindung zwischen dem Schraubelement und dem Federelement kann durch ein Mitnehmerelement gebildet werden, in das das Schraubelement einschraubbar ist und an dem das der Drückernuss abgewandte Ende des Federelementes haltend angeordnet ist. Das Mitnehmerelement bildet einen Reiter, der eine Gewindebohrung aufweist, in die der Gewindeschaft des Schraubelementes eingeschraubt ist. Wird das Schraubelement in Drehbewegung versetzt, wird der Reiter zwischen der Position des Minimalwertes der Federvorspannung und der Position des Maximalwertes der Federvorspannung verstellt. Der Minimalwert der Federvorspannung wird erreicht, wenn das Mitnehmerelement die der Drückernuss zugewandte Position einnimmt, und der Maximalwert der Federvorspannung wird erreicht, wenn das Mitnehmerelement die der Drückernuss abgewandte Position einnimmt. Das Mitnehmerelement kann dabei in einer insbesondere im Schlossgehäuse eingebrachten Nut geführt sein, durch die der Verstellweg des Mitnehmerelementes auf den Verstellweg zwischen dem Minimalwert und dem Maximalwert der Federvorspannung begrenzt ist. Weiterhin wird durch die Führung des Mitnehmerelementes in der Nut erreicht, dass sich das Mitnehmerelement bei Verdrehung des Schraubelementes nicht mitdreht.The connection between the screw element and the spring element can be formed by a driver element into which the screw element can be screwed and on which the end of the spring element remote from the pusher nut is held. The driver element forms a rider, which has a threaded bore into which the threaded shank of the screw element is screwed. If the screw element is set in rotary motion, the tab is adjusted between the position of the minimum value of the spring preload and the position of the maximum value of the spring preload. The minimum value of the spring preload is achieved when the driver element assumes the position facing the pusher nut, and the maximum value of the spring preload is achieved when the driver element assumes the position facing away from the pusher nut. The driver element can be guided in a particular introduced in the lock housing groove, by which the adjustment of the driver element is limited to the adjustment between the minimum value and the maximum value of the spring preload. Furthermore, it is achieved by the leadership of the driver element in the groove that the driver element does not rotate with rotation of the screw.

Vorteilhafterweise weist das Schlossgehäuse eine Seitenwand auf, und die Drehachse durchstößt die Seitenwand, insbesondere kann die Drehachse die Seitenwand senkrecht oder unter einem Winkel durchstoßen. Wird das Schlossgehäuse auf der Oberfläche eines Glasflügels einer Ganzglastür angeordnet, so kann sich die Seitenwand senkrecht zur
Oberfläche des Glasflügels erstecken. In der Seitenwand kann eine Öffnung eingebracht sein, die mit der Drehachse des Schraubelementes fluchtet und durch die ein Werkzeug zur Drehung des Schraubelementes hindurchführbar ist oder durch die sich ein Schraubenkopf des Schraubelementes hindurch erstreckt. Befindet sich das Schlossgehäuse in einer montierten Anordnung auf der Oberfläche des Glasflügels, so kann das Schraubelement weiterhin mittels eines Werkzeuges in Drehbewegung versetzt werden, um die Federvorspannung des Federelementes zu verändern, ohne dass das Schloss demontiert werden muss oder ohne dass ein Deckel abgenommen werden muss. Das Werkzeug kann durch die Öffnung in der Seitenwand des Schlossgehäuses hindurch eingeführt werden, um dieses in das Schraubelement einzusetzen. Das Werkzeug kann beispielsweise ein Schraubendreher oder ein Innensechskantschlüssel sein. Alternativ kann sich ein Schraubenkopf des Schraubelementes durch die Öffnung in der Seitenwand hindurch erstecken oder in der Öffnung selbst angeordnet sein, um ein Schraubwerkzeug in den Schraubenkopf des Schraubelementes einzusetzen und dieses zu verdrehen. Mit weiterem Vorteil kann die Öffnung in der Seitenwand des Schlossgehäuses eingebracht sein, die in Bezug auf die Einbaulage des Schlossgehäuses nach unten weist, wodurch die Öffnung in der Seitenwand des Schlossgehäuses für einen Betrachter nicht direkt sichtbar ist und es wird verhindert, dass Verunreinigungen in die Öffnung eintreten können. Weiterführend kann ein Stopfen vorgesehen sein, der zum Verschluss der Öffnung dienen kann.
Advantageously, the lock housing on a side wall, and the axis of rotation pierces the side wall, in particular, the axis of rotation, the side wall perpendicular or at an angle punctured. If the lock housing is arranged on the surface of a glass wing of a glass door, the side wall can be perpendicular to the
Extend the surface of the glass wing. In the side wall, an opening may be introduced, which is aligned with the axis of rotation of the screw and through which a tool for rotating the screw is passed or through which a screw head of the screw extends. If the lock housing is in an assembled arrangement on the surface of the glass wing, then the screw element can continue to be rotated by means of a tool in order to change the spring preload of the spring element without the lock having to be disassembled or without a cover having to be removed , The tool can be inserted through the opening in the side wall of the lock housing to insert it into the screw. The tool may be, for example, a screwdriver or a hex key. Alternatively, a screw head of the screw member may extend through the opening in the side wall or be disposed in the opening itself to insert a screwing tool into the screw head of the screw member and to twist it. With further advantage, the opening in the side wall of the lock housing can be introduced, which points downwards with respect to the installation position of the lock housing, whereby the opening in the side wall of the lock housing is not directly visible to a viewer and it prevents impurities in the Opening can occur. In addition, a plug can be provided which can serve to close the opening.

Um das Schraubelement ortsfest im Schlossgehäuse anzuordnen, kann im Schlossgehäuse eine Aufnahme vorgesehen sein, die zur Aufnahme des Schraubelementes dient. Die Aufnahme des Schraubelementes erfolgt dabei derart, dass das Schraubelement weiterhin drehbar ist, ohne, dass sich die Lage des Schraubelementes im Schlossgehäuse verändert. Beispielsweise kann die Aufnahme in Gestalt einer am Schlossgehäuse angegossenen oder aus einem Blechmaterial des Schlossgehäuses herausgebogenen Lasche ausgebildet sein, in der das Schraubelement aufgenommen wird.In order to arrange the screw fixed in the lock housing, a receptacle may be provided in the lock housing, which serves to receive the screw. The inclusion of the screw takes place in such a way that the screw is still rotatable, without that changes the position of the screw in the lock housing. For example, the receptacle may be formed in the form of a cast on the lock housing or bent out of a sheet metal material of the lock housing tab in which the screw is added.

Die Drückernuss kann einen Federarm aufweisen, an dem das Federelement mit dem der Verstelleinheit abgewandten Ende angeordnet ist. Damit erstreckt sich das Federelement zwischen dem Federarm der Drückernuss und dem Mitnehmerelement der Verstelleinheit. Das Federelement kann als Zugfeder ausgebildet sein, wobei alternativ das Federelement auch als Druckfeder ausgeführt sein kann. Ist das Federelement als Druckfeder ausgeführt, wird der Maximalwert der Federvorspannung dann erreicht, wenn das Mitnehmerelement in der dem Federarm zugewandten Position angeordnet ist, und der Minimalwert der Federvorspannung wird dann erreicht, wenn das Mitnehmerelement einen maximalen Abstand zum Federarm der Drückernuss aufweist. Die Verstelleinheit kann bei Ausbildung des Federelementes als Druckfeder auf gleiche Weise ausgestaltet sein.The follower may have a spring arm on which the spring element is arranged with the end facing away from the adjustment. Thus, the spring element extends between the spring arm of the follower and the driver element of the adjustment. The spring element may be formed as a tension spring, wherein alternatively, the spring element may also be designed as a compression spring. If the spring element is designed as a compression spring, the maximum value of the spring preload is achieved when the driver element is arranged in the spring arm facing position, and the minimum value of the spring preload is achieved when the driver element has a maximum distance from the spring arm of the follower. The adjustment can be configured in the same way when forming the spring element as a compression spring.

Weiterführend kann die Drückernuss einen Hebelarm aufweisen, wobei der Hebelarm zum Anschlag an ein Anschlagelement ausgebildet ist, und wobei das Anschlagelement insbesondere verstellbar ist, um die Nulllage eines in der Drückernuss aufnehmbaren Türdrückers einzustellen. Das Anschlagelement kann vorteilhafterweise als Stellschraube ausgebildet sein, die in einem Schraubenaufnahmeteil im Schlossgehäuse aufgenommen ist. Die Erstreckungsrichtung des Hebelarms und die Erstreckungsrichtung der Stellschraube können etwa einen rechten Winkel zueinander einnehmen, und wenn der Anschlagpunkt zwischen der Stellschraube und dem Hebelarm durch ein Verdrehen der Stellschraube im Schraubenaufnahmeteil verändert wird, kann die Nulllage der Drückernuss ebenfalls verändert werden. Das Federelement spannt dabei die Drückernuss um die Betätigungsachse der Drückernuss derart vor, dass der Hebelarm in der Nulllage der Drückernuss gegen das Schraubelement, insbesondere gegen das Ende des Gewindeschaftes des Schraubelementes, anschlägt. Abhängig von der Einschraubtiefe des Schraubelementes im Schraubenaufnahmeteil verlagert sich der Anschlagpunkt des Hebelarms gegen die Stellschraube, und die Nulllage der Drückernuss und folglich des Türdrückers kann verstellt werden.Furthermore, the follower may have a lever arm, wherein the lever arm is designed to abut against a stop element, and wherein the stop element is adjustable, in particular, in order to adjust the zero position of a door handle that can be received in the follower. The stop element can advantageously be designed as a set screw which is received in a screw receiving part in the lock housing. The extension direction of the lever arm and the extension direction of the adjusting screw can take about a right angle to each other, and if the abutment point between the screw and the lever arm is changed by a rotation of the screw in the screw receiving part, the zero position of Follower also changed. The spring element biases the follower to the operating axis of the follower in such a way that the lever arm in the zero position of the follower against the screw, in particular against the end of the threaded shank of the screw abuts. Depending on the depth of engagement of the screw in the screw receiving part of the stop point of the lever arm moves against the screw, and the zero position of the follower and thus the door handle can be adjusted.

Ist die Nulllage des Türdrückers eingestellt, kann das Anschlagelement mit einer chemischen Schraubensicherung versehen werden, so dass sich das Anschlagelement nicht selbsttätig verstellt. Insbesondere bei Ganzglastüren tritt der optische Effekt auf, dass bei nicht-rechtwinkliger Lage des Türdrückers sein Spielgelbild und der durchscheinende Gegentürdrücker besonders hervortritt. Die Nulllagenverstellbarkeit ermöglicht es daher, dass optische Gesamtbild der Türanordnung zu verbessern. Zum Verstellen des Anschlagelementes, insbesondere zum Verstellen der Stellschraube, kann im Schlossgehäuse eine Öffnung vorgesehen sein, durch die ein Werkzeug einführbar ist, um die Stellschraube in Drehbewegung zu versetzen und damit den Anschlagpunkt zwischen der Stellschraube und dem Hebelarm zu verändern.If the zero position of the door handle set, the stop element can be provided with a chemical thread lock, so that the stop element does not move automatically. Particularly in the case of all-glass doors, the visual effect occurs that in the case of a non-rectangular position of the door handle, its gelatinous appearance and the translucent counter-push-piece handle particularly stand out. The zero-position adjustability therefore makes it possible to improve the total optical image of the door arrangement. For adjusting the stop element, in particular for adjusting the adjusting screw, an opening may be provided in the lock housing, through which a tool can be inserted in order to set the adjusting screw in rotary motion and thus to change the attachment point between the adjusting screw and the lever arm.

Gemäß einer weiteren vorteilhaften Ausführungsform des erfindungsgemäßen Schlosses kann die Drückernuss eine Aufnahmeöffnung zur Aufnahme eines Türdrückers aufweisen, in der wenigstens ein Klemmelement angeordnet ist, das sich in einem nicht verspannten Zustand in den Montagebereich des Türdrückers, insbesondere in den Montagebereich eines Vierkantschaftes des Türdrückers, hinein erstreckt. Das Klemmelement ist federnd ausgeführt, und wenn der Vierkantschaft des Türdrückers durch die Aufnahmeöffnung, die insbesondere als Vierkantöffnung in der Drückernuss ausgebildet sein kann, eingeführt wird, wird das Klemmelement elastisch zurückgedrückt. Beispielsweise kann das Klemmelement als federelastisches Blechelement ausgebildet sein, und das Blechelement kann in wenigstens einer Vierkantfläche der Aufnahmeöffnung eingebracht sein. Fertigungstechnisch wird zwischen dem Vierkantschaft des Türdrückers und der Vierkantöffnung in der Drückernuss eine leichte Spielpassung vorgesehen, um den Vierkantschaft ohne Pressung in die Vierkantöffnung fügen zu können. Ist der Türdrücker in der Drückernuss montiert, so ist es wünschenswert, dass die Verbindung zwischen dem Türdrücker und der Drückernuss möglichst spielarm ist. Durch die erfindungsgemäße Anordnung eines Klemmelementes wird der Vierkantschaft des Türdrückers gegen eine dem Klemmelement gegenüberliegende Vierkantfläche in der Aufnahmeöffnung gepresst, die der Anordnung gegenüberliegt. Insbesondere können zwei Klemmelemente in zwei aneinander angrenzenden, rechtwinklig zueinander ausgeführten Vierkantflächen ausgebildet sein, und beim Fügen des Vierkantschaftes in der Vierkantöffnung muss lediglich die Kraft überwunden werden, die notwendig ist, um das oder die Klemmelemente aus dem Montagebereich des Vierkantschaftes zurückzudrücken. Ist der Vierkantschaft in der Vierkantöffnung eingefügt, wird das Spiel zwischen dem Vierkantschaft und der Vierkantöffnung durch das eine oder die beiden Klemmelemente herausgedrückt. Im Ergebnis ist eine spielfreie Anordnung eines Türdrückers in einer Drückernuss möglich.According to a further advantageous embodiment of the lock according to the invention, the follower has a receiving opening for receiving a door handle, in which at least one clamping element is arranged, which is in a non-strained state in the mounting region of the door handle, in particular in the mounting area of a square shank of the door handle, in extends. The clamping element is designed to be resilient, and when the square shank of the door handle through the receiving opening, which may be formed in particular as a square opening in the handle nut can, is introduced, the clamping element is pushed back elastically. For example, the clamping element may be formed as a resilient sheet metal element, and the sheet metal element may be incorporated in at least one square surface of the receiving opening. Manufacturing technology is provided between the square shank of the door handle and the square opening in the pusher a slight clearance fit to add the square shaft without pressure in the square opening can. If the door handle is mounted in the follower, it is desirable for the connection between the door handle and the follower to be as free of play as possible. The inventive arrangement of a clamping element of the square shank of the door handle is pressed against a clamping element opposite the square surface in the receiving opening, which is opposite to the arrangement. In particular, two clamping elements may be formed in two mutually adjacent, rectangularly executed square surfaces, and when joining the square shank in the square opening only the force has to be overcome, which is necessary to push back the one or more clamping elements from the mounting area of the square shank. If the square shank is inserted in the square opening, the clearance between the square shank and the square opening is pushed out by the one or both clamping elements. As a result, a play-free arrangement of a door handle in a pusher is possible.

Gemäß einer vorteilhaften Weiterbildung des erfindungsgemäßen Schlosses kann ein Schlossgehäusedeckel vorgesehen sein, der auf das Schlossgehäuse aufsetzbar ist, um einen geschlossenen Aufnahmeraum zur Aufnahme der Schließmechanik, insbesondere zur Aufnahme der Drückernuss, zu bilden. Vorteilhafterweise können seitlich zur Betätigungsachse zwei Durchgangslöcher vorgesehen sein, die sich durch das Schlossgehäuse und durch den Schlossgehäusedeckel hindurch erstrecken, und durch die Durchgangslöcher können Befestigungselemente hindurchgeführt werden, um Drückerbeschläge auf dem Schlossgehäuse beziehungsweise auf dem Schlossgehäusedeckel anzuordnen. Damit wird bei einem Schloss, das als Schloss für eine Ganzglastür ausgebildet ist, eine Durchverschraubung von Drückerbeschlägen ermöglicht. Die Durchgangslöcher können symmetrisch zur Betätigungsachse im Schlossgehäuse und im Schlossgehäusedeckel eingebracht sein, wobei die Durchgangslöcher im Schlossgehäuse mit den Durchgangslöchern im Schlossgehäusedeckel fluchten. In Bezug auf die Einbaulage des Schlosses können die Durchgangslöcher horizontal und seitlich zur Drückernuss angeordnet sein, um Standard-Drückerbeschläge aufnehmen zu können. Alternativ können die Durchgangslöcher diagonal angeordnet sein, und die Anordnung der Durchgangslöcher kann dem Standard der Drückerbeschläge angepasst sein. Folglich können weiterführend auch horizontal-oval geformte Durchgangslöcher vorgesehen sein, um Standard-Beschläge mit verschiedenen Stichmaßen oder mit verschiedenen Offset-Maßen verwenden zu können. Zur Aufnahme von Klemmkräften bei der Montage des Schlosses kann die Laibung der Durchgangslöcher als Stützhülse ausgebildet sein. Damit können standardmäßig Drückerrosetten mit DIN-Befestigungsstichmaß von 38mm eingesetzt werden. Bei normalen Schlössern werden Rosette und Gegenrosette miteinander verschraubt, was jedoch für Schlösser für Ganzglastüren bislang nicht möglich war. Durch die erfindungsgemäße Ausgestaltung der Durchgangslöcher im Schlossgehäuse beziehungsweise im Schlossgehäusedeckel eines Schlosses für eine Ganzglastür können folglich DIN-Drückerrosetten aufgesetzt und durch das Türblatt miteinander verschraubt werden.According to an advantageous development of the lock according to the invention, a lock housing cover can be provided, which can be placed on the lock housing to form a closed receiving space for receiving the lock mechanism, in particular for receiving the follower. Advantageously, two through holes can be provided laterally to the actuation axis, which extend through the lock housing and through the lock housing cover, and can pass through the through holes Fastening elements are passed to arrange handle fittings on the lock housing or on the lock housing cover. This is in a lock, which is designed as a lock for a glass door, a screw-through of handle fittings allows. The through holes may be symmetrical to the actuation axis in the lock housing and in the lock housing cover, wherein the through holes in the lock housing are aligned with the through holes in the lock housing cover. With respect to the installation position of the lock, the through holes can be arranged horizontally and laterally to the follower to accommodate standard handle fittings can. Alternatively, the through holes may be arranged diagonally, and the arrangement of the through holes may be adapted to the standard of the handle fittings. Consequently, horizontally-oval shaped through-holes can be further provided in order to use standard fittings with different stitch sizes or with different offset dimensions can. To accommodate clamping forces during assembly of the lock, the reveal of the through holes may be formed as a support sleeve. As a standard, pusher rosettes with DIN fixing stitches of 38mm can be used. In normal locks rosette and counter rosette are bolted together, but this was not possible for locks for glass doors so far. Due to the inventive design of the through holes in the lock housing or in the lock housing cover of a lock for a glass door consequently DIN handle rosettes can be placed and screwed together through the door leaf.

Das Schloss kann eine Schlossfalle aufweisen, die durch Drehung der Drückernuss um die Betätigungsachse zwischen einer aus dem Schlossgehäuse hervorspringenden und einer in das Schlossgehäuse zurückgezogenen Position bewegbar ist, wobei die Schlossfalle mittels einer Montageschraube an einem Fallenschaft montierbar ist, so dass die Schlossfalle in zwei 180° zueinander gedrehten Positionen am Fallenschaft montierbar ist. Mit Vorteil kann die Schlossfalle wenigstens einen streifenförmigen Kunststoffsteg aufweisen, wobei die Schlossfalle insbesondere zwei seitliche Kunststoffstege aufweisen kann, so dass wenigstens der eine und vorzugsweise beide Kunststoffstege den Kontaktkörper zum Kontakt der Schlossfalle mit einem Sperrgegenstück, beispielsweise mit einem Schließblech, bildet. Weiterführend kann die Schlossfalle Kunststoffstege aufweisen, die sich über der Schlossfalle in Richtung zum Fallenschaft hinweg erstrecken, um den Kontakt der Schlossfalle zur Führung im Schlossgehäuse durch die Kunststoffstege zu bilden. Weiterführend kann das Schlossgehäuse und/oder der Schlossgehäusedeckel Fallenführungselemente aufweisen, wobei die Fallenführungselemente vorzugsweise als in das Schlossgehäuse und/oder in den Schlossgehäusedeckel eingelassene Kunststoffdämpfungselemente ausgebildet sind, die den Kontaktkörper zwischen der Schlossfalle und dem Schlossgehäuse und/oder dem Schlossgehäusedeckel bilden.The lock may comprise a latch which is movable by rotation of the follower about the actuating axis between a protruding from the lock housing and a retracted into the lock housing position, wherein the lock latch means a mounting screw can be mounted on a latch shaft, so that the latch can be mounted in two 180 ° to each other rotated positions on the latch shaft. Advantageously, the latch may comprise at least one strip-shaped plastic web, wherein the latch may in particular have two lateral plastic webs, so that at least one and preferably both plastic webs forms the contact body for contact of the latch with a locking counterpart, for example with a strike plate. In addition, the latch may comprise plastic webs which extend over the latch in the direction of the latch shaft to form the contact of the latch to the guide in the latch housing through the plastic webs. Furthermore, the lock housing and / or the lock housing cover may comprise latch guide elements, wherein the latch guide elements are preferably designed as plastic damping elements embedded in the lock housing and / or in the lock housing cover, which form the contact body between the lock latch and the lock housing and / or the lock housing cover.

Ist die Schlossfalle in zwei 180° zueinander gedrehten Positionen am Fallenschaft montierbar, kann das Schloss sowohl für rechts als auch für links schließende Türen Verwendung finden. Insbesondere Ganzglastüren sind aufgrund der geringen Eigendämpfung des Türblattes besonders geräuschsensibel. Daher ist es wünschenswert, sämtliche Geräuschquellen zu eliminieren, so dass eine gedämpfte Anordnung der Schlossfalle im Schlossgehäuse eine einfache, wirkungsvolle Dämpfung bildet. Weist die Schlossfalle Kunststoffstege auf, die die Kontaktkörper zum Kontakt mit dem Sperrgegenstück bilden, kann eine weitere Dämpfung der Schlossfalle erreicht werden. Ein wesentlicher Geräuschfaktor ist das Aufschlaggeräusch der Schlossfalle auf das Sperrgegenstück, wodurch eine Schiebebewegung in die Schlossfalle eingeleitet wird. Durch die Dämpfung mittels der Kunststoffstege wird sowohl der Kontakt zu der Schlossfalle zum Sperrgegenstück als auch der Kontakt der Schlossfalle im Schlossgehäuse gedämpft.If the latch can be mounted on the latch shaft in two positions rotated 180 ° relative to one another, the lock can be used for both right and left-closing doors. In particular, all-glass doors are particularly noise sensitive due to the low internal damping of the door leaf. Therefore, it is desirable to eliminate all sources of noise, so that a damped arrangement of the latch in the lock housing forms a simple, effective damping. If the lock catch has plastic webs which form the contact bodies for contact with the locking counterpart, a further damping of the lock catch can be achieved. A significant noise factor is the impact sound of the latch on the counterpart counterpart, whereby a sliding movement is initiated in the latch. By damping by means of the plastic webs is both the contact with the latch to the locking counterpart and the contact of the latch in the lock housing damped.

Das Schlossgehäuse weist Fallenführungselemente auf, die vorzugsweise als in das Schlossgehäuse eingelassene Kunststoffdämpfungselemente ausgebildet sind, die den Kontaktkörper zwischen der Schlossfalle und dem Schlossgehäuse bilden. Die Fallenführungselemente können aus verschleißfestem Kunststoff ausgebildet sein und einen kreisrunden Querschnitt aufweisen. Damit können die Fallenführungselemente gehäuseseitig in Sackbohrungen eingebracht und formschlüssig vom montierten Schlossgehäusedeckel gehalten werden. Die Fallenführungselemente können maßlich so ausgelegt und positioniert sein, dass im montierten Zustand eine Spielpassung zwischen der Schlossfalle und dem Schlossgehäuse entsteht. Insbesondere bei Aufschlagen der Schlossfalle auf das Sperrgegenstück entsteht eine leichte Kippbewegung der Schlossfalle um das Spiel zwischen der Schlossfalle und der Fallenführung. Dabei schlägt die Schlossfalle gegen das Schlossgehäuse und erzeugt ein zusätzliches Geräusch, welches durch die erfindungsgemäßen Kunststoffstege sowohl an der Schlossfalle als auch durch die Fallenführungselemente im Schlossgehäuse beziehungsweise im Schlossgehäusedeckel gedämpft wird.The lock housing has latch guide elements, which are preferably designed as embedded in the lock housing plastic damping elements, which form the contact body between the latch and the lock housing. The latch guide elements may be formed of wear-resistant plastic and have a circular cross-section. Thus, the case guide elements can be placed on the housing side in blind holes and held in a form-fitting manner from the mounted lock housing cover. The latch guide elements can be dimensionally designed and positioned so that a clearance fit between the latch and the lock housing arises in the mounted state. In particular, upon impact of the latch bolt on the locking counterpart creates a slight tilting movement of the latch to the game between the latch and the latch guide. The latch strikes against the lock housing and generates an additional noise, which is damped by the plastic webs according to the invention both on the lock latch and by the latch guide elements in the lock housing or in the lock housing cover.

In den Figuren 1a und 1b ist ein Schloss 1 mit einem geöffneten Schlossgehäuse 10 dargestellt. Im Schlossgehäuse 10 ist eine Drückernuss 11 drehbar um eine Betätigungsachse 12 aufgenommen. An der Drückernuss 11 ist ein Federelement 13 angeordnet, welche als Zugfeder ausgebildet ist und die die Drückernuss 11 um die Betätigungsachse 12 rotatorisch vorspannt. Die Verbindung des Federelementes 13 zum Schlossgehäuse 10 umfasst eine Verstelleinheit 14. Mit der Verstelleinheit 14 kann die Federvorspannung im Federelement 13 verändert werden. Die Drückernuss 11 ist in der Nulllage dargestellt, sodass ein in der Drückernuss 11 aufgenommener Türdrücker eine horizontale Lage einnimmt.
Erfindungsgemäß weist die Verstelleinheit 14 ein Schraubelement 15 auf, das mit dem Federelement 13 verbunden ist, so dass bei Verdrehung des Schraubelementes 15 um die Drehachse 16 die Federvorspannung im Federelement 13 verstellbar ist. Die Verbindung zwischen dem Schraubelement 15 und dem Federelement 13 umfasst ein Mitnehmerelement 17, in das das Schraubelement 15 eingeschraubt ist. Über die Aufnahme 21 ist das Schraubelement 15 ortsfest im Schlossgehäuse 10 aufgenommen, wobei die Aufnahme des Schraubelementes 15 in der Aufnahme 21 die Drehbewegung des Schraubelementes 15 um die Drehachse 16 erlaubt. Damit kann das Mitnehmerelement 17 nach Art eines Reiters entlang des Gewindeschaftes des Schraubelementes 15 verfahren werden, und die Federvorspannung im Federelement 13 ist stufenlos verstellbar.
In the FIGS. 1a and 1b a lock 1 is shown with an open lock housing 10. In the lock housing 10, a follower 11 is rotatably received about an actuating axis 12. At the pusher 11 is arranged a spring element 13, which is designed as a tension spring and which biases the pusher 11 about the actuating axis 12 rotationally. The connection of the spring element 13 to the lock housing 10 comprises an adjustment unit 14. With the adjustment unit 14, the spring preload in the spring element 13 can be changed. The pusher 11 is shown in the zero position, so that a recorded in the pusher 11 door handle occupies a horizontal position.
According to the invention, the adjusting unit 14 has a screw element 15, which is connected to the spring element 13, so that upon rotation of the screw element 15 about the axis of rotation 16, the spring bias in the spring element 13 is adjustable. The connection between the screw 15 and the spring element 13 comprises a driver element 17, in which the screw 15 is screwed. About the receptacle 21, the screw 15 is fixedly received in the lock housing 10, wherein the recording of the screw 15 in the receptacle 21 allows the rotational movement of the screw 15 about the rotation axis 16. Thus, the driver element 17 can be moved in the manner of a rider along the threaded shank of the screw 15, and the spring preload in the spring element 13 is continuously adjustable.

Das Schloss 1 ist für die Verwendung an einer Ganzglastür ausgebildet und kann mit einem Gehäuseboden 36 auf der Oberfläche der Ganzglastür aufgesetzt werden. Das Schlossgehäuse 10 ist seitlich durch eine Seitenwand 18 berandet, und in der Seitenwand 18 ist eine Öffnung 19 eingebracht. Die Öffnung 19 ist in einer Position in der Seitenwand 18 eingebracht, in der sich die Drehachse 16 etwa mittig durch die Öffnung 19 hindurch erstreckt. Folglich kann das Schraubelement 15 mit einem Werkzeug um die Drehachse 16 verdreht werden, so dass die Verstellung der Federvorspannung mittels der Verstelleinheit 14 ermöglicht ist, ohne das Schlossgehäuse 10 zu öffnen.The lock 1 is designed for use on a glass door and can be fitted with a housing bottom 36 on the surface of the all-glass door. The lock housing 10 is bounded laterally by a side wall 18, and in the side wall 18, an opening 19 is introduced. The opening 19 is inserted in a position in the side wall 18, in which the axis of rotation 16 extends approximately centrally through the opening 19 therethrough. Consequently, the screw 15 can be rotated with a tool about the axis of rotation 16, so that the adjustment of the spring bias is made possible by means of the adjusting unit 14 without opening the lock housing 10.

Durch das Federelement 13 wird die Drückernuss 11 um die Betätigungsachse 12 vorgespannt, und die Drückernuss 11 dient zur Aufnahme eines Türdrückers. Wird der Türdrücker betätigt, kann eine Schlossfalle 31 in das Schlossgehäuse 10 zurückgezogen werden. Die Schlossfalle 31 ist mittels einer Montageschraube 32 an einem Fallenschaft 33 angebracht, und die Wirkverbindung zwischen dem Fallenschaft 33 und der Drückernuss 11 wird über einen Schieber 37 gebildet.By the spring element 13, the follower 11 is biased about the actuating axis 12, and the follower 11 serves to receive a door handle. If the door handle is actuated, a latch 31 can be pulled back into the lock housing 10. The latch 31 is attached by means of a mounting screw 32 to a latch shaft 33, and the operative connection between the latch shaft 33 and the follower 11 is formed by a slide 37.

Die Drehachse 16 des Schraubelementes 15 ist zur Seitenwand 18 des Schlossgehäuses 10 unter einem Winkel angeschrägt. Der Winkel ist derart bestimmt, dass durch die Öffnung 19 ein Werkzeug eingeführt werden kann, um mit dem Werkzeug das Schraubelement 15 verdrehen zu können. Zugleich bildet die angeschrägte Anordnung der Drehachse 16 eine Verstellrichtung des Mitnehmerelementes 17, durch die das Mitnehmerelement 17 im Abstand zur Drückernuss 11 verstellbar ist, so dass auch die Federvorspannung des Federelementes 13 entsprechend verändert werden kann. Beispielsweise ist der Winkel der Drehachse 16 zur Seitenwand 18 des Schlossgehäuses 10 mit etwa 45° bemessen. Seitlich zum Aufnahmeloch 42 zur Aufnahme der Drückernuss 11 sind Durchgangslöcher 30 in das Schlossgehäuse 10 eingebracht, die sich durch das Schlossgehäuse 10 und durch einen nicht gezeigten Schlossgehäusedeckel hindurch erstrecken, und durch die Durchgangslöcher 30 können Befestigungselemente hindurchgeführt werden, um Drückerbeschläge auf dem Schlossgehäuse 10 beziehungsweise auf dem Schlossgehäusedeckel anzuordnen. Damit wird eine Durchverschraubung von Drückerbeschlägen auf dem Schlossgehäuse 1 ermöglicht. Die Durchgangslöcher 30 sind symmetrisch zur Betätigungsachse im Schlossgehäuse und im Schlossgehäusedeckel eingebracht, wobei die Durchgangslöcher im Schlossgehäuse mit den Durchgangslöchern im Schlossgehäusedeckel fluchten. In Bezug auf die Einbaulage des Schlosses 1 können die Durchgangslöcher 30 horizontal angeordnet sein, um Standard-Drückerbe-schläge aufnehmen zu können. In den Figuren 2a und 2b ist ein weiteres Ausführungsbeispiel eines Schlosses 1 gezeigt, das zur Anordnung an einer Ganzglastür ausgebildet ist. Das Schlossgehäuse 10 ist mit einem Schlossgehäusedeckel 10a gezeigt, das im Bereich der Anordnung der Verstelleinheit 14 aufgebrochen ist. Die Verstelleinheit 14 weist ein Schraubelement 15 auf, das sich entlang einer Drehachse 16 erstreckt, wobei die Drehachse 16 zur Seitenwand 18 des Schlossgehäuses 10 einen rechten Winkel einnimmt. Das Schraubelement 15 besitzt einen Schraubenkopf 20, der in der Öffnung im Schlossgehäuse 10 einsitzt, und etwa mit der Außenseite der Seitenwand 18 abschließt. Die Drückernuss 11 ist auf der der Schlossfalle 31 abgewandten Seite des Schlosses 1 angeordnet, und die Vorspannung des Federelementes 13 an der Drückernuss 11 kann durch Verstellung des Mitnehmerelementes 17 auf gleiche Weise mittels der Verstelleinheit 14 erfolgen, wie bereits im ersten Ausführungsbeispiel dargelegt.The axis of rotation 16 of the screw 15 is tapered to the side wall 18 of the lock housing 10 at an angle. The angle is determined such that a tool can be inserted through the opening 19 in order to be able to rotate the screw element 15 with the tool. At the same time, the tapered arrangement of the axis of rotation 16 forms an adjustment of the driver 17, through which the driver 17 is adjustable at a distance from the follower 11, so that the spring bias of the spring element 13 can be changed accordingly. For example, the angle of the rotation axis 16 to the side wall 18 of the lock housing 10 is dimensioned at about 45 °. Laterally to the receiving hole 42 for receiving the pusher 11 through holes 30 are inserted into the lock housing 10, which extend through the lock housing 10 and through a lock housing cover, not shown, and through the through holes 30 fasteners can be passed to push lever fittings on the lock housing 10 and to arrange on the lock housing cover. This allows a screw connection of handle fittings on the lock housing 1. The through holes 30 are inserted symmetrically to the actuating axis in the lock housing and in the lock housing cover, wherein the through holes in the lock housing are aligned with the through holes in the lock housing cover. Regarding the Installation position of the lock 1, the through holes 30 may be arranged horizontally to accommodate standard handle shocks can. In the FIGS. 2a and 2b a further embodiment of a lock 1 is shown, which is designed to be arranged on a glass door. The lock housing 10 is shown with a lock housing cover 10a, which is broken in the region of the arrangement of the adjustment unit 14. The adjusting unit 14 has a screw element 15 which extends along an axis of rotation 16, wherein the axis of rotation 16 to the side wall 18 of the lock housing 10 assumes a right angle. The screw 15 has a screw head 20 which is seated in the opening in the lock housing 10, and approximately closes with the outside of the side wall 18. The pusher 11 is disposed on the side facing away from the latch 31 of the lock 1, and the bias of the spring element 13 on the pusher 11 can be done by adjusting the driver 17 in the same manner by means of the adjustment 14, as already stated in the first embodiment.

Die Figuren 3a und 3b zeigen ein erfindungsgemäßes Schloss 1 mit einer Drückernuss 11, die drehbar im Schlossgehäuse 10 aufgenommen ist. Das Schlossgehäuse 10 ist mit einem Schlossgehäusedeckel 10a gezeigt, und die Drückernuss 11 weist einen Hebelarm 23 auf, der zum Anschlag an ein Anschlagelement 24 dient, wobei das Anschlagelement 24 in Gestalt einer Stellschraube 24 ausgebildet ist. Die Stellschraube 24 ist in einem Schraubenaufnahmeteil 25 eingeschraubt und erstreckt sich etwa rechtwinklig zur Erstreckungsrichtung des Hebelarms 23. Wird die Stellschraube 24 in das Schraubenaufnahmeteil 25 weiter eingeschraubt, wird der Anschlag der Drückernuss 11 im Uhrzeigersinn verstellt, und wird die Stellschraube 24 aus dem Schraubenaufnahmeteil 25 herausgeschraubt, so wird der Anschlag der Drückernuss 11 entgegen dem Uhrzeigersinn verstellt. Um zu vermeiden, dass die Stellschraube 24 zu weit aus dem Schraubenaufnahmeteil 25 herausgeschraubt wird, ist am Schlossgehäusedeckel 10a ein Begrenzungselement 38 angebracht, gegen das der Kopf der Stellschraube 24 anschlagen kann. Um die Stellschraube 24 in Drehbewegung zu versetzen, ist im Schlossgehäuse 10 eine weitere Öffnung 39 eingebracht, durch die ein Werkzeug zum Verdrehen der Stellschraube 24 eingeführt werden kann. Der Schraubenaufnahmeteil 25 ist im Schlossgehäuse 10 angeordnet, und zur Montage kann die Stellschraube 24 in den Schraubenaufnahmeteil 25 eingeschraubt werden, während der Schlossgehäusedeckel 10a noch nicht montiert ist. Ist die Stellschraube 24 in dem Schraubenaufnahmeteil 25 eingeschraubt, kann anschließend der Schlossgehäusedeckel 10a montiert werden, und das Begrenzungselement 38 begrenzt eine Ausschraubbewegung der Stellschraube 24 aus dem Schraubenaufnahmeteil 25.The FIGS. 3a and 3b show an inventive lock 1 with a pusher 11, which is rotatably received in the lock housing 10. The lock housing 10 is shown with a lock housing cover 10a, and the follower 11 has a lever arm 23 which serves to abut a stop element 24, wherein the stop element 24 is formed in the form of a set screw 24. The adjusting screw 24 is screwed into a screw receiving part 25 and extends approximately at right angles to the extension direction of the lever arm 23. If the screw 24 is further screwed into the screw receiving part 25, the stop of the follower 11 is adjusted clockwise, and the adjusting screw 24 from the screw receiving part 25th unscrewed, the stop of the follower 11 is adjusted counterclockwise. Around to avoid that the adjusting screw 24 is unscrewed too far out of the screw receiving part 25, a limiting element 38 is mounted on the lock housing cover 10a, against which the head of the adjusting screw 24 can strike. In order to set the adjusting screw 24 in rotational movement, a further opening 39 is introduced in the lock housing 10, through which a tool for rotating the adjusting screw 24 can be introduced. The screw receiving part 25 is arranged in the lock housing 10, and for mounting the adjusting screw 24 can be screwed into the screw receiving part 25, while the lock housing cover 10 a is not yet mounted. If the adjusting screw 24 is screwed into the screw receiving part 25, then the lock housing cover 10 a can be mounted, and the limiting element 38 limits a unscrewing movement of the adjusting screw 24 from the screw receiving part 25.

Die Figuren 4, 5a und 5b stellen die Drückernuss 11 in einer perspektivischen Ansicht sowie in zwei Seitenansichten dar. Die Drückernuss 11 weist eine Aufnahmeöffnung 26 auf, die als Vierkantöffnung ausgebildet ist. Weiterhin umfasst die Drückernuss 11 einen Federarm 22, und das Federelement 13 ist über ein Verbindungselement 40 an den Federarm 22 anbringbar. Auf der dem Federarm 22 etwa gegenüber liegenden Seite besitzt die Drückernuss 11 einen Hebelarm 23, der zum Anschlag gegen das Anschlagelement 24 ausgebildet ist. Um eine geräuschdämpfende, verschleißarme Oberfläche zum Anschlag des Hebelarms 23 gegen das Anschlagelement 24 zu schaffen, ist im Hebelarm 23 ein Prallelement 28 aus einem verschleißfesten Kunststoffmaterial eingesetzt.The Figures 4, 5a and 5b illustrate the pusher 11 in a perspective view and in two side views. The pusher 11 has a receiving opening 26 which is formed as a square opening. Furthermore, the follower 11 comprises a spring arm 22, and the spring element 13 can be attached to the spring arm 22 via a connecting element 40. On the spring arm 22 approximately opposite side has the follower 11 has a lever arm 23 which is formed to abut against the stop element 24. In order to create a noise-damping, low-wear surface for abutment of the lever arm 23 against the stop element 24, a baffle element 28 made of a wear-resistant plastic material is used in the lever arm 23.

Die Aufnahmeöffnung 26 weist vier Vierkantflächen 29 auf, und in einer Vierkantfläche 29 ist ein Klemmelement 27 in Form eines federelastischen Blechelementes eingesetzt. Das Klemmelement 27 weist eine Ausbuchtung 41 auf, die sich in den Montagebereich eines Vierkantschaftes eines Türdrückers hinein erstreckt, der in die Aufnahmeöffnung 26 eingeführt werden muss. Durch die federelastische Ausbildung des Klemmelementes wird die Ausbuchtung 41 in Richtung zur Vierkantfläche 29 zurückgedrückt, und es entsteht eine klemmende Anordnung des Vierkantschaftes in der Vierkantöffnung, die eine spielfreie Verbindung des Türdrückers mit der Drückernuss ermöglicht.The receiving opening 26 has four square surfaces 29, and in a square surface 29, a clamping element 27 is inserted in the form of a resilient sheet metal element. The clamping element 27 has a Bulge 41, which extends into the mounting region of a square shank of a door handle, which must be inserted into the receiving opening 26. Due to the resilient design of the clamping element, the bulge 41 is pushed back in the direction of the square surface 29, and there is a clamping arrangement of the square shank in the square opening, which allows a backlash-free connection of the door handle with the pusher.

Die Figuren 6a bis 6d zeigen eine Schlossfalle 31 eines Schlosses, das für eine Ganzglastür ausgebildet ist. Die Schlossfalle 31 weist zwei streifenförmige Kunststoffstege 34 auf, die gegenüber dem Grundkörper der Schlossfalle 31 hervorstehen.
