Both handles are accommodated on the shaft element, and an operating element for generating a locking position of at least one of the handles interacts directly with the locking mechanism of the lock unit in that an actuating element protrudes from the rosette of the door fitting and is pressed axially into the rosette in a longitudinal axis and out of it can be pulled out again.
  • the locking mechanism is designed with a split nut, with a shaft element of a first handle interacting with a first part of the nut and a second shaft element with a second handle interacting with a second part of the nut.
  • the parts of the nut can be coupled to one another or separated from one another again. This means that the actual locking mechanism can only be activated with one of the two handles.
  • the door fitting has an actuating element which can be rotated in its longitudinal axis to lock the handle, whereby the handle movement of the handle can be blocked and then released again when the actuating element is turned back.

STAND DER TECHNIKSTATE OF THE ART

Türgarnituren mit einer einseitig verriegelbaren Handhabe finden insbesondere für Innentüren eines Gebäudes Anwendung, beispielsweise für Türen von Sanitärräumen. Die Türgarnituren haben dabei wie gewohnt zwei Handhaben, von denen sich eine auf jeder Seite eines Türblattes befindet, wenn diese an ein Türblatt angebracht sind. Einseitig verriegelbare Türgarnituren sind allerdings so ausgeführt, dass zwar eine einseitige Verriegelung einer oder beider Handhaben der Türgarnitur auf nur einer Seite in Verbindung mit einer Handhabe erreicht werden kann, jedoch muss auf der abgewandten Seite der Anordnung eines Bedienelementes für die Verriegelung die Möglichkeit erhalten bleiben, die Verriegelung zu lösen und mit der verriegelten Handhabe beispielsweise im Notfall die Tür zu öffnen.Door sets with a handle that can be locked on one side are used in particular for the interior doors of a building, for example for doors in sanitary rooms. As usual, the door sets have two handles, one of which is located on each side of a door leaf when they are attached to a door leaf. However, door sets that can be locked on one side are designed in such a way that one-sided locking of one or both handles of the door set can be achieved on only one side in conjunction with a handle, but the possibility must be retained on the opposite side of the arrangement of a control element for the locking. to release the lock and use the locked handle to open the door, for example in an emergency.

Ferner offenbart die DE 20 2013 011573 U1 ein durch ein Schaftelement hindurch geführtes, länglich ausgebildetes Notentriegelungselement, das sich von der verriegelbaren Handhabe bis in eine gegenüber liegende Handhabe erstreckt und das durch Einleiten einer Drehbewegung das Verrriegelungselement aus der Sperrstellung in der Rosette herausführt. Die DE 20 2013 011573 U1 offenbart allerdings kein Adapterelement, das in einem Halsabschnitt der Handhabe eingebracht ist und das auf dem Schaftelement aufgenommen ist. Die EP 3 067 491 B1 offenbart eine Türgarnitur mit einer einseitig verriegelbaren Handhabe, und die Türgarnitur weist auf beiden Seiten Rosetten zur jeweils gegenüberliegenden Anlage an ein Türblatt auf und es ist ein Schaftelement zur Bildung einer Wirkverbindung mit der Schließmechanik in einer in das Türblatt eingebrachten Schlosseinheit GRW018PWOEP vorgesehen. Auf dem Schaftelement sind dabei beide Handhaben aufgenommen, und ein Bedienelement zur Erzeugung einer Sperrstellung wenigstens einer der Handhaben wirkt unmittelbar mit der Schließmechanik der Schlosseinheit zusammen, indem ein Betätigungselement aus der Rosette der Türgarnitur herausragt und axial in einer Längsachse in die Rosette eingedrückt und aus dieser wieder herausgezogen werden kann. Die Schließmechanik ist zur Erzielung der Sperrwirkung mit einer geteilten Nuss ausgeführt, wobei ein Schaftelement einer ersten Handhabe mit einem ersten Teil der Nuss und ein zweites Schaftelement mit einer zweiten Handhabe mit einem zweiten Teil der Nuss zusammenwirkt. Durch das Eindrücken und Herausziehen des Bedienelementes können dabei die Teile der Nuss miteinander gekoppelt oder wieder voneinander getrennt werden. So kann erreicht werden, dass die eigentliche Schließmechanik nur noch mit einer der beiden Handhaben aktiviert werden kann.For example, the reveals DE 20 2013 011573 U1 a door set with a handle that can be locked on one side. For this purpose, a locking means is provided, which can be brought into a locking position by means of manual operation and through which the handle can be rotationally blocked on a rosette. Furthermore, the reveals DE 20 2013 011573 U1 an elongated emergency release element guided through a shaft element, which extends from the lockable handle into an opposite handle and which leads the locking element out of the locking position in the rosette by initiating a rotary movement. The DE 20 2013 011573 U1 However, does not disclose an adapter element that is inserted into a neck section of the handle and that is received on the shaft element. The EP 3 067 491 B1 discloses a door fitting with a handle that can be locked on one side, and the door fitting has rosettes on both sides for opposing contact with a door leaf and there is a shaft element for forming an operative connection with the Locking mechanism in a GRW018PWOEP lock unit installed in the door leaf intended. Both handles are accommodated on the shaft element, and an operating element for generating a locking position of at least one of the handles interacts directly with the locking mechanism of the lock unit in that an actuating element protrudes from the rosette of the door fitting and is pressed axially into the rosette in a longitudinal axis and out of it can be pulled out again. To achieve the locking effect, the locking mechanism is designed with a split nut, with a shaft element of a first handle interacting with a first part of the nut and a second shaft element with a second handle interacting with a second part of the nut. By pushing in and pulling out the control element, the parts of the nut can be coupled to one another or separated from one another again. This means that the actual locking mechanism can only be activated with one of the two handles.

Eine weitere Türgarnitur mit einer einseitig verriegelbaren Handhabe ist aus der DE 10 2007 030 655 A1 bekannt. Die Türgarnitur weist ein Betätigungselement auf, das zur Sperrung der Handhabe in seiner Längsachse verdreht werden kann, wodurch die Drückerbewegung der Handhabe gesperrt und bei einer Rückdrehung des Betätigungselementes auch wieder freigegeben werden kann.Another door set with a handle that can be locked on one side is from the DE 10 2007 030 655 A1 known. The door fitting has an actuating element which can be rotated in its longitudinal axis to lock the handle, whereby the handle movement of the handle can be blocked and then released again when the actuating element is turned back.

Aus der US 7 934 754 B2 ist ferner eine Türgarnitur mit zugeordneter Schlosseinrichtung bekannt, die durch eine manuelle Betätigung eines in der Handhabe stirnseitig aufgenommenen Druckknopfes von einer entriegelten Position in eine verriegelte Position überführbar ist.From the US 7,934,754 B2 a door fitting with an associated lock device is also known, which can be moved from an unlocked position to a locked position by manually actuating a push button located in the handle on the front side.

Die bekannten Ausführungen von Türgarnituren mit einer einseitig verriegelbaren Handhabe sind mit einer Vielzahl von Einzelteilen ausgeführt und daher aufwendig in der Herstellung und der Montage. Im Gebrauch sind die bekannten Türgarnituren fehleranfällig und durch die Vielzahl von Einzelteilen kann es zu einem Versagen des Verriegelungsmittels kommen. Zudem sind die Türgarnituren nicht mit jeder handelsüblichen Ausführung einer Schlosseinheit kombinierbar, da die Schließmechanik der Schlosseinheit oder die äußeren Abmessungen der Schlosseinheit an die spezielle einseitig verriegelbare Türgarnitur angepasst sein muss.The known versions of door fittings with a handle that can be locked on one side are made with a large number of individual parts and are therefore complex to manufacture and assemble. In use, the well-known door sets are prone to errors and are caused by the A large number of individual parts can cause the locking means to fail. In addition, the door sets cannot be combined with every commercially available version of a lock unit, since the locking mechanism of the lock unit or the external dimensions of the lock unit must be adapted to the special one-sided lockable door set.

OFFENBARUNG DER ERFINDUNGDISCLOSURE OF INVENTION

Es ist die der Erfindung zugrunde liegende Aufgabe, eine Türgarnitur, insbesondere für eine Innentür eines Gebäudes mit einer einseitig verriegelbaren Handhabe, so weiterzubilden, dass die Türgarnitur mit dem Verriegelungsmittel einfach ausgeführt wird und eine Verriegelung der Handhabe ermöglicht wird, ohne dass die Schließmechanik und insbesondere die Schlosseinheit an das Verriegelungsmittel der Türgarnitur angepasst werden muss. Darüber hinaus soll die Türgarnitur ein einfaches und schlichtes Design behalten können, ohne dass zusätzlich zur Handhabe insbesondere separate Bedienelemente als zusätzliche Bestandteile der Handhabe unmittelbar wahrgenommen werden.It is the object underlying the invention to develop a door set, in particular for an interior door of a building with a handle that can be locked on one side, in such a way that the door set with the locking means is designed simply and the handle can be locked without the locking mechanism and in particular the lock unit must be adapted to the locking means of the door fitting. In addition, the door fitting should be able to maintain a simple and unpretentious design without separate operating elements in addition to the handle being directly perceived as additional components of the handle.

Diese Aufgabe wird ausgehend von einer Türgarnitur gemäß dem Anspruch gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This task is solved based on a door fitting according to the claim. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt die Lehre ein, dass ein Verriegelungsmittel in oder an dem Halsabschnitt der Handhabe aufgenommen ist, welches mittels einer manuellen Betätigung in eine Sperrstellung bringbar ist, in der mittels des Verriegelungsmittels die Handhabe an der Rosette drehblockiert werden kann.The invention includes the teaching that a locking means is accommodated in or on the neck section of the handle, which can be brought into a locking position by means of a manual actuation, in which the handle can be rotationally blocked on the rosette by means of the locking means.

Kerngedanke der Erfindung ist die Integration eines Verriegelungsmittels im Halsabschnitt der Handhabe, der abhängig vom Design der Türgarnitur beispielsweise als Grundbestandteil einen Zylinderkörper oder einen länglichen Körper mit einem ovalen oder rechteckigen Querschnitt bildet. Beispielsweise sind Handhaben bekannt, die L-förmig ausgeführt sind und einen Drückerabschnitt und einen abgewinkelten Halsabschnitt umfassen, wobei der Drückerabschnitt zur manuellen Bedienung dient und wobei der Halsabschnitt sich etwa quer zum Drückerabschnitt in der gleichen Längsachse erstreckt wie auch das Schaftelement, das das Türblatt und damit auch die Schlosseinheit durchwandert.The core idea of the invention is the integration of a locking means in the neck section of the handle, which, depending on the design of the door fitting, forms, for example, a cylindrical body or an elongated body with an oval or rectangular cross section as a basic component. For example, handles are known that are L-shaped and include a handle section and an angled neck section, the handle section being used for manual operation and the neck section extending approximately transversely to the handle section in the same longitudinal axis as the shaft element that holds the door leaf and so that the lock unit also moves through.

Ein besonderer Vorteil liegt in der von der Schlosseinheit unabhängigen Sperrmöglichkeit der Handhabe. Mit der erfindungsgemäßen Türgarnitur können verschiedene Türstärken in einem Dickenunterschied von beispielsweise 9mm abdecken (beispielhaft ausgeführt mit einer Dicke von 35mm bis 44mm), ohne zusätzliche Bauteile oder spezieller Montage.A particular advantage is that the handle can be locked independently of the lock unit. With the door fitting according to the invention, different door thicknesses can be covered with a difference in thickness of, for example, 9mm (exemplified with a thickness of 35mm to 44mm), without additional components or special assembly.

Im Sinne der Erfindung bildet eine Rosette ein oder mehrere Bauteile, die noch vor dem Schlosskasten in, an oder vor dem Türblatt montiert ist bzw. sind. Damit kann die Verriegelung der Handhabe an einer Flachrosette beispielsweise mit einer Dicke von 2mm bis 3mm erfolgen, die Rosette kann alternativ oder ergänzend auch als eine Schraubrosette, eine Klipprosette oder eine Sonstige Rosette ausgebildet sein. Die Verriegelung der Handhabe und schließlich des Verriegelungsmittels kann beispielsweise auch in einem Glastürschlosskasten erfolgen, wenn die Rosette oder ein gleichwirkendes Bauteil insbesondere zur drehbaren Aufnahme des Halsabschnittes der Handhabe im Schlosskastengehäuse integriert oder als Bestandteil desselben ausgebildet ist. Insbesondere kann die Rosette mehrteilig ausgebildet sein, wobei die Verriegelung des Verriegelungsmittels in oder an nur einem Bestandteil der mehrteiligen Rosette erfolgen kann.In the sense of the invention, a rosette forms one or more components that are mounted in, on or in front of the door leaf in front of the lock case. This means that the handle can be locked on a flat rosette, for example with a thickness of 2mm to 3mm; the rosette can alternatively or additionally be designed as a screw rosette, a clip rosette or another rosette. The handle and finally the locking means can also be locked, for example, in a glass door lock case if the rosette or an equivalent component, in particular for rotatably receiving the neck section of the handle, is integrated in the lock case housing or is designed as a part of the same. In particular, the rosette can be designed in several parts, wherein the locking of the locking means can take place in or on only one component of the multi-part rosette.

Ein weiterer vorteilhafter Aspekt der erfindungsgemäßen Türgarnitur liegt in der minimalistischen Konstruktion und durch die Reduzierung der Bauteile ist es möglich, die gesamte Verriegelungsmechanik so kleinbauend zu gestalten, dass diese bis auf das Bedienelement nirgends sichtbar aufträgt und die sichtbare Unterkonstruktion, etwa die Rosette, muss nur mit einer beispielhaften Dicke von 2 mm ausgeführt sein. Dadurch lassen sich auch Griffe gestalten, welche die Unterkonstruktion komplett verdecken und eine Verriegelung ist in der Handhabe integriert. Damit kann auch beispielsweise bei WC - Türen auf die Schlüsselrosetten verzichtet werden, was dem im Markt gewünschten minimalistischen Design einer Türgarnitur damit noch besser entsprechen kann.Another advantageous aspect of the door fitting according to the invention lies in the minimalist design and by reducing the number of components it is possible to make the entire locking mechanism so small that it is not visible anywhere except for the control element and the visible substructure, such as the rosette, only needs to be be designed with an exemplary thickness of 2 mm. This means that handles can be designed that completely cover the substructure and a lock is integrated into the handle. This means that the key rosettes can also be dispensed with on toilet doors, for example, which can correspond even better to the minimalist design of a door set desired in the market.

Erfindungsgemäß soll das Verriegelungsmittel in oder an dem Halsabschnitt so aufgenommen werden, dass dieses in und aus einer Sperrstellung bewegt werden kann, sodass das Verriegelungsmittel in der Sperrstellung die Handhabe an der Rosette drehblockieren kann. Die Rosette ist im Sinne der Erfindung ein Bauteil der Türgarnitur, das nur außen an ein Türblatt angebracht wird und nicht in dieses hineinragt, ausgenommen mit angeformten Schraubdomen. Die Rosette weist Aufnahmeöffnungen für die Handhaben auf, in die der Halsabschnitt der Handhaben mit der Endseite drehbar aufgenommen und/oder gelagert ist. Die Rosette kann dabei auch mehrteilig sein und als Grundköroper ein Verstärkungselement aufweisen, das an das Türblatt montiert wird und das mit einer außenseitigen Abdeckung versehen wird, das vorliegend ebenfalls als Teil der Rosette verstanden wird.According to the invention, the locking means is to be accommodated in or on the neck section in such a way that it can be moved into and out of a locking position, so that the locking means can rotationally block the handle on the rosette in the locking position. For the purposes of the invention, the rosette is a component of the door fitting that is only attached to the outside of a door leaf and does not protrude into it, except with molded screw domes. The rosette has receiving openings for the handles, in which the neck section of the handles is rotatably received and/or stored with the end side. The rosette can also be made up of several parts and have a reinforcing element as the base body, which is mounted on the door leaf and which is provided with an external cover, which is also understood here as part of the rosette.

Das Adapterelement dient insbesondere als Zwischenelement zwischen dem Schaftelement und der Handhabe, und der Halsabschnitt kann hohl ausgeführt sein, sodass das Adapterelement im Halsabschnitt der Handhabe verdrehfest aufgenommen ist. Damit wird der Vorteil genutzt, dass innerhalb oder an dem Halsabschnitt oder innerhalb oder an dem Adapterelement das Verriegelungsmittel angeordnet wird, und das Verriegelungsmittel kann manuell in die Sperrstellung und aus dieser auch wieder heraus bewegt werden.The adapter element serves in particular as an intermediate element between the shaft element and the handle, and the neck section can be made hollow, so that the adapter element is accommodated in the neck section of the handle in a rotationally fixed manner. This takes advantage of that the locking means is arranged within or on the neck section or within or on the adapter element, and the locking means can be manually moved into the locking position and out of it again.

Die Beweglichkeit des Verriegelungsmittels muss dabei nicht zwingend in der Längsachse erfolgen, und es ist auch denkbar, das Verriegelungsmittel so mit dem Halsabschnitt der Handhabe zu verbinden oder im Halsabschnitt unterzubringen, dass dieses durch eine Drehbewegung in der Längsachse oder durch eine quer zur Längsachse verlaufende Druckbewegung die Verriegelung der Handhabe an der Rosette erzeugen kann. Dabei kann das Verriegelungsmittel sowohl im oder am Halsabschnitt selber als auch im oder am Adapterelement aufgenommen sein.The mobility of the locking means does not necessarily have to be in the longitudinal axis, and it is also conceivable to connect the locking means to the neck section of the handle or to accommodate it in the neck section in such a way that it can be activated by a rotary movement in the longitudinal axis or by a pressure movement running transversely to the longitudinal axis can create the locking of the handle on the rosette. The locking means can be accommodated both in or on the neck section itself and in or on the adapter element.

Mit besonderem Vorteil ist das Verriegelungsmittel mittels eines Schlittenelementes gebildet, das in oder an dem Adapterelement beweglich aufgenommen ist. Insbesondere dann, wenn das Verriegelungsmittel in der Längsachse des Schaftelementes und damit auch in der Längsachse des Halsabschnittes beziehungsweise des Adapterelementes linear beweglich sein soll, eignet sich die Ausführung des Verriegelungsmittels als ein Schlittenelement, das in oder an dem Adapterelement oder zumindest innerhalb des Halsabschnittes gleitbeweglich geführt wird. Das Schlittenelement kann dann manuell so bewegt werden, dass dieses in Richtung zur Rosette vorgeschoben wird, um das Adapterelement und damit auch die Handhabe an der Rosette zu verriegeln und das Schlittenelement kann manuell zurückgezogen werden, um die Drehbeweglichkeit der Handhabe um die Längsachse wieder freizugeben.The locking means is particularly advantageously formed by means of a carriage element which is movably received in or on the adapter element. In particular, if the locking means is to be linearly movable in the longitudinal axis of the shaft element and thus also in the longitudinal axis of the neck section or the adapter element, the design of the locking means as a slide element is suitable, which is slidably guided in or on the adapter element or at least within the neck section becomes. The carriage element can then be moved manually so that it is advanced towards the rosette in order to lock the adapter element and thus also the handle on the rosette and the carriage element can be manually retracted in order to release the rotational mobility of the handle about the longitudinal axis again.

Alternativ zu einer Drehbeweglichkeit des Schlittenelementes um die Längsachse herum oder alternativ zu einer Beweglichkeit des Schlittenelementes quer zur Längsachse ist es von besonderem Vorteil, wenn das Schlittenelement parallel zur bzw. mit der Längsachse des Schaftelementes in oder an dem Adapterelement beweglich geführt ist, denn dann kann das Schlittenelement unmittelbar manuell in und aus der Sperrstellung bewegt werden.As an alternative to a rotational mobility of the carriage element around the longitudinal axis or alternatively to a mobility of the carriage element transversely to the longitudinal axis, it is particularly advantageous if the carriage element is movably guided in or on the adapter element parallel to or with the longitudinal axis of the shaft element, because then the carriage element can be moved manually into and out of the locking position.

Die Rosette weist zur Verriegelbarkeit eine Aussparung auf, in die ein Sperrabschnitt des Verriegelungsmittels in der Sperrstellung eingeschoben werden ist. Das Verriegelungsmittel insbesondere in der Form des Schlittenelementes kann eine längliche Erstreckung mit einem Querschnitt aufweisen, der beispielsweise viereckig ausgeführt ist, und der Sperrabschnitt bildet beispielsweise einen vorderseitigen Abschnitt oder einen Fortsatz des Schlittenelementes, der in die Aussparung der Rosette eingeschoben werden kann. Der restliche länglich ausgeführte Körper des Schlittenelementes verbleibt dabei in der komplementär ausgeführten Aufnahme im oder am Adapterelement.For lockability, the rosette has a recess into which a locking section of the locking means can be inserted in the locking position. The locking means, in particular in the form of the slide element, can have an elongated extension with a cross section that is, for example, square, and the locking section forms, for example, a front section or an extension of the slide element, which can be inserted into the recess in the rosette. The remaining elongated body of the slide element remains in the complementary receptacle in or on the adapter element.

Die Aufnahme für das Verriegelungsmittel im Adapterelement ist vorteilhafterweise eine Führungsnut im Adapterelement, sodass in der Führungsnut das Verriegelungsmittel, insbesondere in Form des Schlittenelementes, in der Längsachse beweglich geführt ist. Dabei kann vorteilhaft die Ausführung des Halsabschnittes genutzt werden und die Führungsnut kann mittels des rohrförmig ausgeführten Halsabschnittes zu einem Führungskanal geschlossenen werden, in dem das Verriegelungsmittel gehalten und geführt ist.The receptacle for the locking means in the adapter element is advantageously a guide groove in the adapter element, so that the locking means, in particular in the form of the slide element, is movably guided in the longitudinal axis in the guide groove. The design of the neck section can be advantageously used and the guide groove can be closed by means of the tubular neck section to form a guide channel in which the locking means is held and guided.

Gemäß einer vorteilhaften Weiterbildung der Türgarnitur weist der Halsabschnitt der Handhabe eine Öffnung auf, durch die hindurch ein Bedienelement geführt ist, über das das Verriegelungsmittel manuell bewegbar ist. Die Öffnung ist vorteilhafterweise länglich sich in der Längsachse erstreckend ausgeführt, beispielsweise als Schlitz oder als Kulisse, und das Bedienelement kann ein Zapfen, ein abragender Stift oder ein flacher Schiebeknopf sein, der von der Außenseite des Halsabschnittes bedienbar ist und somit eine manuelle Bewegbarkeit des Verriegelungsmittels erreicht werden kann, insbesondere wenn das Verriegelungsmittel als Schlittenelement ausgeführt ist. Ist das Bedienelement als Schiebeknopf ausgeführt, kann dieser die Öffnung im Halsabschnitt im Wesentlichen vollständig überdecken, und ist das Bedienelement als Schiebepin, als Schiebestift, als Schiebezapfen oder als sonstiger schiebebeweglicher Schaft ausgeführt, kann die Breite der länglich ausgeführten Öffnung dem Durchmesser oder der Breite des Bedienelementes entsprechen.According to an advantageous development of the door fitting, the neck section of the handle has an opening through which an operating element is guided, via which the locking means can be moved manually. The opening is advantageously designed to be elongated, extending in the longitudinal axis, for example as a slot or as a link, and the operating element can be a pin, a projecting pin or be a flat sliding button which can be operated from the outside of the neck section and thus manual mobility of the locking means can be achieved, in particular if the locking means is designed as a slide element. If the operating element is designed as a sliding button, it can essentially completely cover the opening in the neck section, and if the operating element is designed as a sliding pin, as a sliding pin, as a sliding pin or as another slidingly movable shaft, the width of the elongated opening can correspond to the diameter or the width of the correspond to the control element.

Dabei kann mit weiterem Vorteil an der Position des Bedienelementes innerhalb der Öffnung bereits optisch erfasst werden, ob die Handhabe der Türgarnitur verriegelt ist oder nicht. Insbesondere kann eine durch die Öffnung sichtbare Seite des Verriegelungsmittels, insbesondere des Schlittenelementes, farblich so gekennzeichnet sein, dass das Schlittenelement beispielsweise rot in Erscheinung tritt, wenn sich dieses in der Sperrstellungbefindet und das Schlittenelement kann beispielsweise grün in Erscheinung treten, wenn dieses aus der Sperrstellung wieder herausgeführt ist.With further advantage, it can be optically detected from the position of the control element within the opening whether the handle of the door fitting is locked or not. In particular, a side of the locking means, in particular of the slide element, visible through the opening can be color-coded so that the slide element appears red, for example, when it is in the locked position and the slide element can appear green, for example, when it is out of the locked position is brought out again.

Erfindungsgemäß ist vorgesehen, dass durch das Schaftelement hindurch ein länglich ausgebildetes Notentriegelungselement hindurch geführt ist, das sich von der verriegelbaren Handhabe bis in eine gegenüberliegende Handhabe erstreckt. Das Schaftelement ist beispielsweise als Mehrkantelement und insbesondere als Vierkantelement ausgeführt, und das Schaftelement besitzt einen innenseitigen Durchgang, durch den hindurch das Notentriegelungselement geführt ist, beispielsweise gemäß der Ausführung der Gebrauchsmusterschrift DE 20 2013 011 573 U1 . Das Notentriegelungselement kann als Flachstab ausgeführt sein, und wenn in das Notentriegelungselement von der Seite der gegenüberliegenden Handhabe eine Drehbewegung eingeleitet wird, ist gemäß der Erfindung vorgesehen, dass das Notentriegelungselement dabei so mit dem Verriegelungsmittel zusammenwirkt, dass eine Drehbewegung des Notentriegelungselementes das Verriegelungsmittel aus der Sperrstellung in der Rosette herausführt. Damit kann, insbesondere im Notfall, auch von der nicht verriegelbaren Handhabe der Türgarnitur das Verriegelungsmittel in Anordnung im oder am Halsabschnitt aus der Sperrstellung wieder herausgeführt werden, wobei die Drehbewegung in das Notentriegelungselement von der nicht verriegelbaren Handhabe ausgehen kann.According to the invention it is provided that an elongated emergency release element is guided through the shaft element and extends from the lockable handle into an opposite handle. The shaft element is designed, for example, as a polygonal element and in particular as a square element, and the shaft element has an inside passage through which the emergency unlocking element is guided, for example according to the design of the utility model DE 20 2013 011 573 U1 . The emergency release element can be designed as a flat bar, and when inserted into the emergency release element from the side opposite If a rotary movement is initiated, it is provided according to the invention that the emergency unlocking element interacts with the locking means in such a way that a rotary movement of the emergency unlocking element leads the locking means out of the locked position in the rosette. This means that, particularly in an emergency, the locking means can also be moved out of the locking position from the non-lockable handle of the door fitting in an arrangement in or on the neck section, whereby the rotational movement into the emergency unlocking element can originate from the non-lockable handle.

Das beispielsweise als Flachstab ausgeführte Notentriegelungselement kann mit einer Endseite an der nicht verriegelbaren Handhabe mit einem Werkzeugaufnahmeelement verbunden sein, und ein Benutzer der Türgarnitur kann beispielsweise mit einem Schraubendreher oder mit einer Münze von der nicht verriegelbaren, insbesondere raumaußenseitigen Handhabe eine Drehbewegung in das Notentriegelungselement einleiten, das dann so mit dem Verriegelungsmittel zusammenwirkt, dass die Drehbewegung im Notentriegelungselement eine Verschiebebewegung des Verriegelungsmittels auslöst. Letzteres kann folglich aus der Sperrstellung in der Rosette herausgeführt werden.The emergency unlocking element, designed for example as a flat rod, can be connected to a tool receiving element with one end side on the non-lockable handle, and a user of the door fitting can initiate a rotary movement into the emergency unlocking element, for example with a screwdriver or with a coin from the non-lockable, in particular room-outside, handle, which then interacts with the locking means in such a way that the rotational movement in the emergency unlocking element triggers a displacement movement of the locking means. The latter can therefore be moved out of the locked position in the rosette.

Beispielsweise ist ein Schneckenelement vorgesehen, das mit dem Notentriegelungselement drehverbunden ist und wenigstens einen Schneckengang aufweist, auf dem ein Vorsprung des Verriegelungsmittels entlang geführt ist, sodass mit einer mit dem Notentriegelungselement in das Schneckenelement einleitbaren Drehbewegung das Verriegelungsmittel in der Längsachse aus der Sperrstellung bewegbar ist. Das Notentriegelungselement kann beispielsweise in einfacher Form mit dem Schneckenelement formschlüssig verbunden sein, sodass die Drehbewegung des Notentriegelungselementes in das Schneckenelement überführbar ist. Auf der gegenüberliegenden Seite des Notentriegelungselementes kann das Werkzeugaufnahmeelement ebenfalls lediglich drehstarr mit dem Notentriegelungselement insbesondere formschlüssig verbunden sein.For example, a screw element is provided which is rotatably connected to the emergency unlocking element and has at least one screw flight, along which a projection of the locking means is guided, so that the locking means can be moved in the longitudinal axis out of the locked position with a rotary movement that can be initiated into the screw element with the emergency unlocking element. The emergency unlocking element can, for example, be positively connected to the screw element in a simple form, so that the rotational movement of the emergency unlocking element flows into the screw element is transferable. On the opposite side of the emergency unlocking element, the tool receiving element can also only be connected in a rotationally rigid manner to the emergency unlocking element, in particular in a form-fitting manner.

In einer alternativen erfindungsgemäßen Ausführungsform der Türgarnitur mit Notentriegelungselement ist dieses als Stößel ausgebildet, in welchen von der Seite der gegenüber liegenden Handhabe eine Schubbewegung einleitbar ist, und wobei das Notentriegelungselement so mit dem Verriegelungsmittel zusammenwirkt, dass eine Schubbewegung des Notentriegelungselementes das Verriegelungsmittel aus der Sperrstellung in der Rosette herausführt.In an alternative embodiment of the door fitting according to the invention with an emergency unlocking element, this is designed as a plunger in which a pushing movement can be initiated from the side of the handle located opposite, and the emergency unlocking element interacts with the locking means in such a way that a pushing movement of the emergency unlocking element moves the locking means out of the locked position the rosette leads out.

Dazu ist beispielsweise ein Mitnahmeelement vorgesehen, das mit dem Stößel schubverbunden ist und eine Anformung aufweist, welche in formschlüssiger Verbindung mit einem Vorsprung des Verriegelungsmittels steht, sodass mit einer mit dem Notentriegelungselement in das Mitnahmeelement eingeleiteten Schubbewegung in der Längsachse das Verriegelungsmittel aus der Sperrstellung bewegbar ist. Der Halsabschnitt der Handhabe weist auf der dem Verriegelungsmittel gegenüber liegenden Seite vorzugsweise eine stirnseitige Öffnung auf, durch welche das Notentriegelungsmittel zum Zwecke der Einleitung einer Schubbewegung mittels eines Stiftes oder dergleichen zugänglich ist.For this purpose, for example, a driving element is provided, which is connected in a thrust manner to the plunger and has a molding which is in a positive connection with a projection of the locking means, so that the locking means can be moved out of the locking position with a thrust movement in the longitudinal axis initiated with the emergency unlocking element into the driving element . The neck section of the handle preferably has a front opening on the side opposite the locking means, through which the emergency unlocking means is accessible for the purpose of initiating a pushing movement by means of a pin or the like.

Zudem kann das Notentriegelungselement der vorgenannten Ausführungsform eine Signalfläche aufweisen, wobei die gegenüber liegende Handhabe mit einer Öffnung ausgebildet ist, sodass in der Sperrstellung des Verriegelungsmittels die Signalfläche durch die Öffnung sichtbar ist und eine Verriegelung anzeigt. Als Signalfläche dient vorzugsweise die Stirnseite des länglichen Notentriegelungselements, welche zu diesem Zwecke beispielsweise mit roter Farbe bedeckt ist. Die Öffnung der Handhabe, durch welche die Signalfläche sichtbar ist, entspricht in diesem Fall der vorgenannten Öffnung stirnseitig des Halsabschnittes.In addition, the emergency unlocking element of the aforementioned embodiment can have a signal surface, with the opposite handle being designed with an opening, so that in the locked position of the locking means, the signal surface is visible through the opening and indicates a lock. The end face of the elongated emergency unlocking element, which is covered with red paint for this purpose, preferably serves as the signal surface. The Opening of the handle, through which the signal surface is visible, corresponds in this case to the aforementioned opening on the front side of the neck section.

Weiterhin kann im Halsabschnitt der verriegelbaren Handhabe ein Magnetelement aufgenommen sein, das das Verriegelungsmittel magnetisch in die Sperrstellung zieht und/oder das Verriegelungsmittel in dieser sichert und welches das Verriegelungsmittel magnetisch in eine Freigabestellung zieht und/oder dieses in der Freigabestellung sichert. Das Magnetelement ist beispielsweise als runde Magnetscheibe ausgeführt und angrenzend an das Schneckenelement im Halsabschnitt ortsfest aufgenommen, insbesondere kann das Magnetelement im Adapterelement fest angeordnet sein.Furthermore, a magnetic element can be accommodated in the neck section of the lockable handle, which magnetically pulls the locking means into the locking position and/or secures the locking means in this and which magnetically pulls the locking means into a release position and/or secures it in the release position. The magnetic element is designed, for example, as a round magnetic disk and is accommodated in a stationary manner adjacent to the screw element in the neck section; in particular, the magnetic element can be fixedly arranged in the adapter element.

Es ist besonders vorteilhaft, wenn das Magnetelement mit einer ersten Kontaktfläche des Verriegelungsmittels zusammenwirkt, um dieses in die Sperrstellung zu ziehen und/oder in dieser zu sichern, wobei das Magnetelement mit einer zweiten Kontaktfläche des Verriegelungsmittels zusammenwirkt, um dieses in die Freigabestellung zu ziehen und/oder in dieser zu sichern.It is particularly advantageous if the magnetic element cooperates with a first contact surface of the locking means in order to pull it into the locking position and/or secure it in this, wherein the magnetic element cooperates with a second contact surface of the locking means in order to pull it into the release position and /or to secure it in this.

Die sich insbesondere gegenüberstehenden Kontaktflächen können innenseitig an Vorsprüngen des Schlittenelementes ausgebildet sein, und das beispielsweise scheibenförmige Magnetelement befindet sich zwischen den beiden sich gegenüberstehenden Vorsprüngen. Zwischen den beiden Kontaktflächen ist das Magnetelement eingefasst, und bewegt ein Benutzer das Schlittenelement in die Sperrstellung, so erzeugt das wechselseitig gegenüberliegende Anziehen des Magneten an die Kontaktflächen eine haptische Information darüber, dass das Verriegelungsmittel in die Sperrstellung bewegt wurde, und wird das Schlittenelement in die Freigabestellung überführt, erfolgt in gleicher Weise eine haptische Information durch das Anziehen des Magneten, sodass der Benutzer darüber informiert ist, ob die Sperrstellung oder die Freigabestellung vorliegt.The particularly opposing contact surfaces can be formed on the inside of projections of the slide element, and the, for example, disk-shaped magnetic element is located between the two opposing projections. The magnetic element is enclosed between the two contact surfaces, and if a user moves the carriage element into the locking position, the mutually opposite attraction of the magnet to the contact surfaces generates haptic information that the locking means has been moved into the locking position, and the carriage element is moved into the When the release position is transferred, a haptic one takes place in the same way Information by attracting the magnet so that the user is informed whether the locking position or the unlocking position is present.

Figur 1 stellt in einer perspektivischen Ansicht eine Türgarnitur 1 mit einer erfindungsgemäß ausgeführten einseitig verriegelbaren Handhabe 10 dar. Die Türgarnitur 1 weist auf an sich bekannte Weise zwei Handhaben 10 auf, und eine Handhabe 10 kann sich mit Bezug auf ein nicht dargestelltes Türblatt auf einer Innenseite und eine Handhabe 10 auf einer Außenseite eines Raumes befinden. Die Handhabe 10, der verriegelbar ist, kann sich dabei auf der Rauminnenseite der Tür befinden. Figure 1 shows a perspective view of a door fitting 1 with a one-sided lockable handle 10 designed according to the invention. The door fitting 1 has two handles 10 in a manner known per se, and a handle 10 can be located on one inside and one on the inside with respect to a door leaf, not shown Handle 10 is located on the outside of a room. The handle 10, which can be locked, can be located on the inside of the door.

Die Türgarnitur 1 weist weiterhin Rosetten 11 auf, die zur Anlage an das Türblatt ausgebildet sind und es ist ein Schaftelement 12 gezeigt, das sich zwischen den beiden Handhaben 10 erstreckt und die Schließmechanik eines Schlosskastens durchwandert, das in das Türblatt eingebracht werden kann. Die Handhaben 10 weisen Halsabschnitte 14 auf, und in den Halsabschnitten 14 befinden sich Adapterelemente 13, insbesondere um die Handhaben 10 drehstarr mit dem Schaftelement 12 zu verbinden. Hierfür erstreckt sich das Schaftelement 12 mit seinen Enden abschnittsweise in einen jeweiligen Innendurchgang der Adapterelemente 13 hinein, und der Halsabschnitt 14 der Handhaben 10 ist außenseitig auf dem Adapterelement 13 drehstarr aufgebracht.The door fitting 1 also has rosettes 11 which are designed to rest on the door leaf and a shaft element 12 is shown which extends between the two handles 10 and the locking mechanism a lock case that can be inserted into the door leaf. The handles 10 have neck sections 14, and adapter elements 13 are located in the neck sections 14, in particular in order to connect the handles 10 to the shaft element 12 in a rotationally rigid manner. For this purpose, the shaft element 12 extends with its ends in sections into a respective internal passage of the adapter elements 13, and the neck section 14 of the handle 10 is mounted on the outside of the adapter element 13 in a rotationally rigid manner.

Der Halsabschnitt 14 der Handhabe 10, welche verriegelbar ausgeführt ist, ist aufgebrochen gezeigt, sodass das Adapterelement 13 im Halsabschnitt 14 sichtbar ist. Im Adapterelement 13 ist ein Verriegelungsmittel 15 aufgenommen, und zur Betätigung des Verriegelungsmittels 15 weist dieses ein Bedienelement 22 zur manuellen Bedienung auf, das sich durch eine Öffnung 21 im Halsabschnitt 14 hindurch erstreckt.The neck section 14 of the handle 10, which is designed to be lockable, is shown broken open so that the adapter element 13 is visible in the neck section 14. A locking means 15 is accommodated in the adapter element 13, and in order to actuate the locking means 15, it has an operating element 22 for manual operation, which extends through an opening 21 in the neck section 14.

Wird das Verriegelungsmittel 15 durch manuelle Betätigung des Bedienelementes 22 in Richtung zur Rosette 11 verschoben, so gelangt das Verriegelungsmittel 15 formschlüssig in Eingriff mit der Rosette 11, und da das Verriegelungsmittel 15 im Adapterelement 13 formschlüssig aufgenommen ist und da die Handhabe 10 drehstarr auf dem Adapterelement 13 aufgenommen ist, kann eine Beweglichkeit der Handhabe 10 um eine Längsachse 17 blockiert werden. Im Verriegelungszustand sind beide Handhaben 10 blockiert, da diese über das Schaftelement 12 zueinander drehstarr verbunden sind. Die Verriegelung der Handhaben 10 kann jedoch nur von einer Seite der beiden Handhaben 10 ausgelöst werden, wobei die Handhabe 10, die das Verriegelungsmittel 15 und damit auch das Bedienelement 22 aufweist, beispielsweise auf einer Rauminnenseite, etwa einer Toilette oder einem Besprechungsraum, etc., angebracht ist. Sollen die Handhaben 10 wieder freigegebenen werden, muss das Verriegelungsmittel 15 über das Bedienelement 22 wieder von der Rosette 11 wegbewegt werden, sodass dieses damit außer Eingriff mit der Rosette 11 gebracht wird. An der Handhabe 10, die nicht mit dem Verriegelungsmittel 15 ausgebildet ist, befindet sich rückseitig des Halsabschnittes 14 das Werkzeugaufnahmeelement 31 zur Notentriegelung der verriegelten Handhaben 10.If the locking means 15 is moved in the direction of the rosette 11 by manual actuation of the operating element 22, the locking means 15 comes into positive engagement with the rosette 11, and since the locking means 15 is received in a form-fitting manner in the adapter element 13 and the handle 10 is rotationally rigid on the adapter element 13 is included, mobility of the handle 10 about a longitudinal axis 17 can be blocked. In the locked state, both handles 10 are blocked because they are connected in a rotationally rigid manner to one another via the shaft element 12. However, the locking of the handles 10 can only be triggered from one side of the two handles 10, with the handle 10, which has the locking means 15 and thus also the control element 22, for example on the inside of a room, such as a toilet or a meeting room, etc. is appropriate. If the handles 10 are to be released again, the locking means 15 must be over that Control element 22 can be moved away from the rosette 11 again, so that it is brought out of engagement with the rosette 11. On the handle 10, which is not designed with the locking means 15, the tool receiving element 31 for emergency unlocking of the locked handles 10 is located on the back of the neck section 14.

Figur 2 zeigt eine detailliertere Ansicht des Adapterelementes 13, in dem das Verriegelungsmittel 15 aufgenommen ist, das als Schlittenelement 16 ausgebildet ist. Auf der Oberseite des Schlittenelementes 16 ist das Bedienelement 22 als Teil des Verriegelungsmittels 15 angebracht, welches als Zylinderstift ausgeführt ist. Das Schlittenelement 16 ist in eine Führungsnut des Adapterelementes 13 eingebracht, sodass dieses in der Längsachse 17 axial verlagert werden kann. Zum formschlüssigen Eingriff des Schlittenelementes 16 in die Rosette 11 weist dieses einen Sperrabschnitt 19 auf, der in eine Aussparung 18 in der Rosette 11 eingeschoben werden kann. Figure 2 shows a more detailed view of the adapter element 13, in which the locking means 15 is accommodated, which is designed as a slide element 16. On the top of the carriage element 16, the control element 22 is attached as part of the locking means 15, which is designed as a cylindrical pin. The carriage element 16 is inserted into a guide groove of the adapter element 13 so that it can be axially displaced in the longitudinal axis 17. For positive engagement of the carriage element 16 in the rosette 11, it has a locking section 19 which can be inserted into a recess 18 in the rosette 11.

Figur 3 zeigt in einer weiteren perspektivischen Ansicht die Rosette 11 und das Adapterelement 13, und die Aussparung 18 in der Rosette 11 ist korrespondierend zur Führungsnut 20 im Adapterelement 13 eingebracht. Wird gemäß Figur 2 das Schlittenelement 16 in Richtung zur Rosette 11 nach vorne geschoben, so gelangt der Sperrabschnitt 19 in die Aussparung 18 der Rosette 11 hinein und blockiert eine Verdrehbewegung des Adapterelementes 13 und damit auch der Handhabe 10 relativ zur Rosette 11, die im eingebauten Zustand der Türgarnitur 1 an einem Türblatt starr angebracht ist. Figure 3 shows the rosette 11 and the adapter element 13 in a further perspective view, and the recess 18 in the rosette 11 is made corresponding to the guide groove 20 in the adapter element 13. According to Figure 2 If the carriage element 16 is pushed forward in the direction of the rosette 11, the locking section 19 enters the recess 18 of the rosette 11 and blocks a rotational movement of the adapter element 13 and thus also of the handle 10 relative to the rosette 11, which is in the installed state of the door fitting 1 is rigidly attached to a door leaf.

Die Rosette 11 weist gemäß dem Ausführungsbeispiel ein Verstärkungselement 32 und ein Abdeckelement 34 auf, wobei in das aus einem dickeren Blech ausgebildete Verstärkungselement 32 die Aussparung 18 eingebracht ist, sodass auch größere manuell eingeleitete Drehmomente in das Adapterelement 13 nicht zu einer Beschädigung der Aussparung 18 führen, und wobei das Abdeckelement 34 ein dünneres insbesondere metallisches oder auch nicht metallisches Material aufweisen kann.According to the exemplary embodiment, the rosette 11 has a reinforcing element 32 and a cover element 34, the recess 18 being introduced into the reinforcing element 32 made of a thicker sheet metal, so that larger ones can also be introduced manually Torques in the adapter element 13 do not lead to damage to the recess 18, and the cover element 34 can have a thinner, in particular metallic or non-metallic material.

Figur 4 zeigt einen Querschnitt durch die Türgarnitur 1 mit den beiden Handhaben 10 und den beiden Rosetten 11. In den Halsabschnitten 14 der Handhaben 10 sind die Adapterelemente 13 eingebracht, und im linken Adapterelement 13 ist das Schlittenelement 16 aufgenommen, das das Verriegelungselement 15 bildet. Der Querschnitt zeigt das Schlittenelement 16 mit dem Bedienelement 22, das sich durch die Öffnung 21 im Halsabschnitt 14 zur manuellen Bedienbarkeit hindurch erstreckt. Figure 4 shows a cross section through the door fitting 1 with the two handles 10 and the two rosettes 11. The adapter elements 13 are inserted into the neck sections 14 of the handles 10, and the carriage element 16, which forms the locking element 15, is accommodated in the left adapter element 13. The cross section shows the carriage element 16 with the operating element 22, which extends through the opening 21 in the neck section 14 for manual operation.

Durch das Schaftelement 12 erstreckt sich ein Notentriegelungselement 23 hindurch, das auf der Seite der Anordnung des Verriegelungsmittels 15 mit einem Schneckenelement 24 drehstarr verbunden ist. Damit reicht ein Ende des länglichen Notentriegelungselementes 23 in Anordnung an das Schneckenelement 24 und das gegenüberliegende Ende des Notentriegelungselementes 23 ist mit einem Werkzeugaufnahmeelement 31 zur Notentriegelung verbunden.An emergency unlocking element 23 extends through the shaft element 12 and is connected in a rotationally rigid manner to a screw element 24 on the side where the locking means 15 is arranged. This means that one end of the elongated emergency unlocking element 23 extends into alignment with the screw element 24 and the opposite end of the emergency unlocking element 23 is connected to a tool receiving element 31 for emergency unlocking.

Soll die Türgarnitur 1 in einer Sperrstellung notentriegelt werden, so kann auf der Seite der rechten Handhabe 10 mit einem Werkzeug über das Werkzeugaufnahmeelement 31 eine Drehbewegung in das Notentriegelungselement 23 eingeleitet werden, wodurch auch eine Drehbewegung im Schneckenelement 24 erzeugt wird. Ein Vorsprung 26 am Verriegelungsmittel 15 wird durch einen Schneckengang 25 des Schneckenelementes 24 in der Längsachse 17 von der Rosette 11 weg bewegt, wodurch das Verriegelungsmittel 15 außer Eingriff mit der Rosette 11 gebracht werden kann.If the door fitting 1 is to be emergency unlocked in a locked position, a rotary movement can be initiated into the emergency unlocking element 23 on the side of the right handle 10 using a tool via the tool receiving element 31, whereby a rotary movement is also generated in the screw element 24. A projection 26 on the locking means 15 is moved away from the rosette 11 in the longitudinal axis 17 by a screw flight 25 of the screw element 24, whereby the locking means 15 can be brought out of engagement with the rosette 11.

Rückseitig zum Schneckenelement 24 ist in das Adapterelement 13 ein Magnetelement 27 eingebracht, das mit einer ersten Kontaktfläche 28 und einer gegenüberliegenden Kontaktfläche 29 magnetisch zusammenwirken kann, welche Kontaktflächen 28 und 29 an dem Vorsprung 26 und an einem hinteren Vorsprung 30 sich gegenüberliegend ausgebildet sind.On the back of the screw element 24, a magnetic element 27 is introduced into the adapter element 13, which can interact magnetically with a first contact surface 28 and an opposite contact surface 29, which contact surfaces 28 and 29 are formed opposite one another on the projection 26 and on a rear projection 30.

Die Darstellung zeigt das Verriegelungselement 15 in der Sperrstellung, indem ein vorderseitiger Sperrabschnitt 19 des Verriegelungsmittels 15 formschlüssig in die Rosette 11 eingreift. In dieser gezeigten Position gelangt die zweite Kontaktfläche 29 am hinteren Vorsprung 30 in Kontakt mit dem Magnetelement 27, sodass das Verriegelungsmittel 15 in der Sperrstellung gehalten wird und in dieses einschnappt. Wird das Verriegelungsmittel 15 durch eine manuelle Bedienung aus der Rosette 11 zurückgezogen, so wird der Kontakt des Magnetelementes 27 mit der zweiten Kontaktfläche 29 gelöst und die erste Kontaktfläche 28 wird vom Magnetelement 27 angezogen, die am Vorsprung 26 angebracht ist. In dieser Freigabestellung wird das Verriegelungsmittel 15 durch das Magnetelement 27 ebenfalls gehalten und eingeschnappt. Durch das Magnetelement 27 wird mit dem jeweiligen magnetischen Schnappen eine Haptik für die Bedienung des Verriegelungsmittels 15 erzeugt, sodass in jeder axialen Endlage des Verriegelungsmittels 15 entlang der Längsachse 17 eine Raststellung für einen Bediener erfühlbar ist.The illustration shows the locking element 15 in the locking position, in that a front locking section 19 of the locking means 15 engages in a form-fitting manner in the rosette 11. In this position shown, the second contact surface 29 on the rear projection 30 comes into contact with the magnetic element 27, so that the locking means 15 is held in the locking position and snaps into it. If the locking means 15 is withdrawn from the rosette 11 by manual operation, the contact of the magnetic element 27 with the second contact surface 29 is released and the first contact surface 28 is attracted by the magnetic element 27, which is attached to the projection 26. In this release position, the locking means 15 is also held and snapped in by the magnetic element 27. The magnetic element 27 creates a haptic for operating the locking means 15 with the respective magnetic snap, so that a locking position can be felt by an operator in every axial end position of the locking means 15 along the longitudinal axis 17.

Figur 5 zeigt eine perspektivische Ansicht des Adapterelementes 13 mit dem Verriegelungsmittel 15 in Form des Schlittenelementes 16 in einer Verriegelungsstellung. Weiterhin zeigt die Schnittansicht das Schneckenelement 24 mit dem Schneckengang 25. Dabei ist in der Ansicht erkennbar, dass der Vorsprung 26 mit einer Flanke an dem Schneckengang 25 des Schneckenelementes 24 anliegt. Die Axialposition des Schlittenelementes 16 ist in Richtung zur nicht gezeigten Rosette dargestellt, sodass das Verriegelungsmittel 15 sich in der Sperrstellung befindet. Das Schneckenelement 24 ist mit einem Federelement 33 in eine Ruheposition vorgespannt, sodass sich diese rotatorische Vorspannung auch für das Notentriegelungselement ergibt. Soll die Notentriegelung aktiviert werden, so wird das Schneckenelement 24 entsprechend gegen die Kraft des Federelementes 33 verdreht, wie weiterführend in Figur 6 gezeigt. Figure 5 shows a perspective view of the adapter element 13 with the locking means 15 in the form of the carriage element 16 in a locking position. Furthermore, the sectional view shows the screw element 24 with the screw flight 25. It can be seen in the view that the projection 26 rests with one flank on the screw flight 25 of the screw element 24. The axial position of the carriage element 16 is shown in the direction of the rosette, not shown, so that the locking means 15 is in the locking position located. The screw element 24 is prestressed into a rest position with a spring element 33, so that this rotational prestress also results for the emergency unlocking element. If the emergency release is to be activated, the screw element 24 is rotated accordingly against the force of the spring element 33, as described further in Figure 6 shown.

Figur 6 zeigt die Ansicht des Adapterelementes 13 mit dem Verriegelungsmittel 15 in einer nunmehr entriegelten Position, wobei das Schneckenelement 24 verdreht wurde, und wobei die Verdrehung entgegen der Kraft des Federelementes 33 erfolgt ist. Dadurch, dass der Vorsprung 26 (siehe Fig. 5) auf dem Schneckengang 25 abgleiten konnte, wurde das Verriegelungsmittel 15 in gezeigter Pfeilrichtung von der Rosette wegbewegt, sodass durch die Verdrehung des Schneckenelementes 24 das Verriegelungsmittel 15 von der Sperrstellung in die Freigabestellung überführt wurde. Wird die Verdrehbewegung über das Notentriegelungselement 23 nicht weiter gehalten, so führt das Federelement 33 die Drehbewegung des Schneckenelementes 24 wieder zurück. Figure 6 shows the view of the adapter element 13 with the locking means 15 in a now unlocked position, the screw element 24 being rotated, and the rotation taking place against the force of the spring element 33. Because the projection 26 (see Fig. 5 ) could slip on the screw flight 25, the locking means 15 was moved away from the rosette in the direction of the arrow shown, so that the locking means 15 was transferred from the locking position to the release position by rotating the screw element 24. If the rotational movement is no longer maintained via the emergency release element 23, the spring element 33 returns the rotational movement of the screw element 24 again.

Dadurch, dass der Vorsprung am Verriegelungsmittel 15 nur einseitig am Schneckengang 25 des Schneckenelementes 24 anliegt, wird durch die Rückführung der Drehbewegung des Schneckenelementes 24 durch das Federelement 33 in die in Fig. 5 gezeigte Ruheposition das Verriegelungsmittel 15 nicht wieder in die Sperrstellung überführt. Nur so kann ein erneutes Verriegeln der Handhabe 10 über das Verriegelungsmittel 15 erfolgen. Ansonsten müsste der Benutzer nach jedem Notentriegeln das Verriegelungsmittel 15 zwingend selbst zurückdrehen, um wieder normal im Gebrauch die Handhabe 10 verriegeln zu können. Zudem ist das Federelemente 33 nötig, um bei einer Betätigung der Handhabe 10 dafür zu sorgen, dass sich das Schneckenelement 24 nicht undefiniert mit dreht oder sich dieses verdrehen kann und eventuell so stehen bleibt, dass ein Verriegeln der Handhabe 10 mit dem Verriegelungsmittel 15 nicht mehr möglich ist.Because the projection on the locking means 15 only rests on one side of the screw flight 25 of the screw element 24, the return of the rotary movement of the screw element 24 by the spring element 33 in the in Fig. 5 shown rest position, the locking means 15 is not transferred back into the locking position. This is the only way the handle 10 can be locked again using the locking means 15. Otherwise, the user would have to turn back the locking means 15 himself after each emergency unlocking in order to be able to lock the handle 10 again during normal use. In addition, the spring element 33 is necessary to ensure that the screw element 24 moves when the handle 10 is actuated does not rotate in an undefined manner or it can twist and possibly stops in such a way that locking the handle 10 with the locking means 15 is no longer possible.

Die Figuren 7 und 8 zeigen quergeschnittene Gesamtansichten einer Türgarnitur 1 in Sperr- bzw. Freigabestellung des Verriegelungsmittels 15. Die Türgarnitur 1 umfasst das Notentriegelungsmittel 23 in Gestalt des Stößels 41, durch welches mittels Einleitung einer axialen Schubbewegung von Seiten der gegenüber liegenden, d.h. linken, Handhabe 10 das Verriegelungsmittel 15 von der Sperr- in die Freigabestellung überführbar ist.The Figures 7 and 8 show cross-sectional overall views of a door fitting 1 in the locking or releasing position of the locking means 15. The door fitting 1 includes the emergency unlocking means 23 in the form of the plunger 41, through which the locking means 15 is released by initiating an axial pushing movement from the opposite, ie left, handle 10 can be transferred from the blocked to the released position.

Auf Seiten des Verriegelungsmittels 15 ist der Stößel 41 mittels der Madenschraube 40 mit dem Mitnahmeelement 35 schubverbunden, d.h. dass bei Verschiebung des Notentriegelungselements 23 entlang der Längsachse 17 das Mitnahmeelement 35 mitgeführt wird. Das Mitnahmeelement 35 weist die oberseitig abstehende Anformung 36 auf, welche sich in Eingriff mit dem Verriegelungsmittel 15 befindet und insbesondere in formschlüssiger Verbindung mit dem Vorsprung 26 steht. Über diese formschlüssige Verbindung wird eine axiale Schubbewegung des Notentriegelungselements 23 auf das Verriegelungsmittel 15 übertragen und der Sperrabschnitt 19 des Schlittenelements 16 wird aus der Rosette 11 zurückgeschoben, so dass das Verriegelungsmittel 15 aus der in der Figur 7 dargestellten Sperrstellung in die in Figur 8 dargestellte Freigabestellung überführt wird. Dabei ist die von dem Magnetelement 27 auf die zweite Kontaktfläche 29 ausgeübte Haltekraft zu überwinden.On the side of the locking means 15, the plunger 41 is connected in a sliding manner to the driving element 35 by means of the grub screw 40, that is to say that when the emergency unlocking element 23 is displaced along the longitudinal axis 17, the driving element 35 is carried along. The driving element 35 has the upper-side projecting formation 36, which is in engagement with the locking means 15 and in particular is in a positive connection with the projection 26. Via this positive connection, an axial thrust movement of the emergency unlocking element 23 is transmitted to the locking means 15 and the locking section 19 of the carriage element 16 is pushed back out of the rosette 11, so that the locking means 15 is released from the in the Figure 7 into the locking position shown in Figure 8 shown release position is transferred. The holding force exerted by the magnetic element 27 on the second contact surface 29 must be overcome.

Auf der dem Verriegelungsmittel 15 gegenüber liegenden Seite der Türgamitur 1 weist der Halsabschnitt 14 der Handhabe 10 die stirnseitige Öffnung 38 auf, welche Zugriff auf das Notentriegelungselement 23 ermöglicht. Zum Zwecke der Notentriegelung wird ein durch die Öffnung 38 passender Gegenstand, beispielsweise ein Stift, in Kontakt mit der Stirnseite des Notentriegelungselementes 23 gebracht und sodann eine Schubbewegung in der Längsachse 17 in das Notentriegelungselement 23 eingeleitet, welche auf die vorbeschriebene Art zur Entriegelung des Verriegelungsmittels 15 führt. Das Notentriegelungselement 23 wird durch die in das Innere des Schaftelements 12 eingepresste Führungshülse 39 geführt.On the side of the door fitting 1 opposite the locking means 15, the neck section 14 of the handle 10 has the front opening 38, which enables access to the emergency unlocking element 23. For the purpose of emergency unlocking, a through opening 38 A suitable object, for example a pin, is brought into contact with the end face of the emergency unlocking element 23 and then a pushing movement in the longitudinal axis 17 is initiated into the emergency unlocking element 23, which leads to the unlocking of the locking means 15 in the manner described above. The emergency release element 23 is guided through the guide sleeve 39 pressed into the interior of the shaft element 12.

Die Stirnseite des Notentriegelungselementes 23 ist als Signalfläche 37 ausgebildet, indem sie mit einer Signalfarbe, insbesondere Rot, eingefärbt, beispielsweise lackiert, ist. In der in Figur 7 dargestellten Sperrstellung des Verriegelungsmittels 15 schließt die Signalfläche 37 bündig mit der Kontur der Handhabe 10 ab, so dass die Signalfläche 37 von außen sichtbar ist und den verriegelten Zustand der Türgarnitur 1 signalisiert. Im Falle der in der Figur 8 dargestellten Freigabestellung ist die Signalfläche 37 in das Innere des Schaftelements 12 eingeschoben und somit von außen effektiv nicht mehr sichtbar.The front side of the emergency unlocking element 23 is designed as a signal surface 37 by being colored, for example painted, with a signal color, in particular red. In the in Figure 7 In the locking position of the locking means 15 shown, the signal surface 37 is flush with the contour of the handle 10, so that the signal surface 37 is visible from the outside and signals the locked state of the door fitting 1. In the case of in the Figure 8 In the release position shown, the signal surface 37 is pushed into the interior of the shaft element 12 and is therefore effectively no longer visible from the outside.

Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch macht. Der Umfang der Erfindung ist durch die vorliegenden Patentansprüche definiert.The implementation of the invention is not limited to the preferred exemplary embodiment given above.
