Titel: TürdrückerklemmbefestigungTitle: Lever handle mounting
Die Erfindung betrifft eine Türdrückerklemmbefestigung mit einem in einer Einsteckoffnung eines Türdrückerhalses lösbar eingesetzten und mittels einer den Türdrückerhals durchfassenden Halteschraube in der Einsteckoffnung festlegbaren, mit einer Durchgangsöffnung für die Aufnahme eines Druckerdornes versehenen, im Querschnitt quadratischen Einsatzteil, welches wenigstens eine Bestandteil des Einsatzteiles bildende, federnd elastisch gegen eine Rastverzahnung des in das Einsatzteil einsteckbaren Druckerdornes anstellbare Sperrfeder aufweist.The invention relates to a door handle clamp fastening with a detachably inserted in an insertion opening of a door handle neck and which can be fixed in the insertion opening by means of a retaining screw which extends through the door handle neck and which is provided with a through opening for receiving a printer mandrel and which is resilient in cross section and which forms at least one component of the insert part Has locking spring which can be adjusted elastically against a locking toothing of the printer mandrel which can be inserted into the insert part.
Türdrückerklemmbefestigungen sind im Allgemeinen derart ausgebildet, dass ein Türdrücker eines Türbeschlages fest mit dem Türdrückerdorn verbunden ist, während der zweite Türdrücker mittels einer mit einer Sperrfeder zusammenwirkenden Rastverzahnung lösbar auf den Drücker- dorn aufgesteckt wird. Die Befestigungen beider Türdrücker eines Türbeschlages sind somit im Regelfall unterschiedlich ausgebildet.Door handle clamp fastenings are generally designed in such a way that a door handle of a door fitting is firmly connected to the door handle mandrel, while the second door handle is detachably attached to the handle mandrel by means of a locking toothing which interacts with a locking spring. The fastenings of both door handles of a door fitting are therefore usually designed differently.
Eine gattungsgemäße Klemmbefestigung mit den vorbeschriebenen Merkmalen offenbart die DE-OS 19 30 679, wobei die Rastverzahnung des Druckerdornes eine konkave Längsnut aufweist, in die eine Sperrfeder eingreift, welche sich mit einer buckelartigen Krümmung an einer Wandung der Einsteckoffnung abstützt. Die Einsteckoffnung ist zylindrisch ausgebildet und nimmt über einen Teil ihrer Länge bei einem der beiden Türdrücker das zylindrische Einsteckteil auf.DE-OS 19 30 679 discloses a generic clamp fastening with the features described above, the locking teeth of the printer mandrel having a concave longitudinal groove into which a locking spring engages, which is supported with a hump-like curvature on a wall of the insertion opening. The insertion opening is cylindrical and takes up the cylindrical insertion part over part of its length in one of the two door handles.
Eine Türdrückerverbindung mit einer in eine abgestufte Einsteckoffnung der beiden gegenüberliegenden Türdrücker eingesetzte Einsatzbuchse mit einer abgestuften Durchgangsöffnung beschreibt die DE 74 25 072 U1 , wobei die Einsatzbuchsen mit dem Drückerhals fest verklebt sind und nur einer der beiden Türdrücker mit seiner Einsatzbuchse unter Zwischen- schaltung einer Federlasche die Rastverzahnung eines Druckerdornes überfasst.DE 74 25 072 U1 describes a door handle connection with an insert socket inserted into a stepped insertion opening of the two opposite door handles with a stepped through opening, the insert sockets being firmly glued to the handle neck and only one of the two door handles with its insert socket under intermediate circuit of a spring clip covers the locking teeth of a printer mandrel.
Ein mit einem der beiden Türdrücker fest verbundener Drückerdorn, welcher in der Einsteckoffnung des anderen Türdrückers mittels einer an ei- nem in der Einsteckoffnung fest angeordneten Einsatzteil befindlichen Sperrfeder festgeklemmt wird, ist durch die DE-AS 12 58 758 bekannt geworden. Das Einsatzteil besteht aus zwei gegenüberliegenden Sperrfedern, die mit entsprechend geformten Einbuchtungen in eine im Querschnitt kreisförmige Rastverzahnung des Druckerdornes eingreifen.DE-AS 12 58 758 has made known a handle mandrel which is firmly connected to one of the two door handles and which is clamped in the insertion opening of the other door handle by means of a locking spring located on an insert part fixedly arranged in the insertion opening. The insert part consists of two opposite locking springs which engage with correspondingly shaped indentations in a locking toothing of circular cross section of the printer mandrel.
Ein ausschließlich aus einer Sperrfeder bestehender, in beiden gegenüberliegenden Türdrückern angeordneter Einsatz ist Gegenstand der DE 42 34 870 C1. Die Türdrückerhälse weisen eine abgestufte Einsteckoffnung auf, wobei die die Verrastung in Axial-Richtung des Druckerdornes bewirkende, ein Losteil bildende Sperrfeder in der im Durchmesser größe- ren Stufe der Abstufung der Einsteckoffnung angeordnet ist und die Verdrehsicherung des Druckerdornes durch einen Eingriff des freien Endes des Druckerdornes in die im Durchmesser kleinere Stufe bewirkt wird.An insert consisting exclusively of a locking spring and arranged in both opposite door handles is the subject of DE 42 34 870 C1. The lever handle necks have a stepped insertion opening, the locking spring, which causes the locking in the axial direction of the printer mandrel and forms a loose part, is arranged in the diameter of the step of the insertion opening, and the rotation lock of the printer mandrel is caused by engagement of the free end of the Printer mandrel in the smaller diameter stage is effected.
Aufgabe der Erfindung ist es, eine Türdrückerklemmbefestigung zu schaffen, bei der sowohl das Einsatzteil als auch der Drückerdorn formschlüssig und verdrehsicher im Drückerhals gelagert sind. Dabei sollen mittels des Einsatzteiles Fertigungstoleranzen im Bereich der Einsteckoffnung des Drückerhalses ausgeglichen werden können. Ein wesentlicher Teil der Aufgabe besteht darin, die Türdrückerklemmbefestigung mit Bezug auf beide gegenüberliegende Türdrücker eines Türbeschlages so auszubil- den, dass durch Auswechseln der Einsatzteile eines Türbeschlages mit einer im Durchmesser kleineren oder größeren Durchgangsöffnung mit einfachen Mitteln eine Anpassung an Drückerdorne unterschiedlichen Durchmessers ermöglicht wird. Gleiches gilt für die Anpassbarkeit an im Durchmesser unterschiedlicher Einsteckoffnung im Drückerhals.The object of the invention is to provide a door handle clamp fastening in which both the insert and the handle mandrel are positively and non-rotatably mounted in the handle neck. It should be possible to compensate for manufacturing tolerances in the area of the insertion opening of the pusher neck by means of the insert. An essential part of the task is to design the door handle clamp fastening with reference to both opposite door handles of a door fitting in such a way that, by changing the insert parts of a door fitting with a smaller or larger through opening, they can be easily adapted to handle pins Diameter is made possible. The same applies to the adaptability to different insertion openings in the pusher neck.
Die Erfindung löst die gestellte Aufgabe mit den Merkmalen nach Anspruch 1.The invention solves this problem with the features of claim 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.
Mit der Lehre nach Anspruch 1 erfolgt im Bereich des die Nuten aufweisenden Längenabschnittes der Einsteckoffnung die zug- und druckfeste sowie verdrehsichere Lagerung des Einsatzteiles in der Einsteckoffnung des Türdrückerhalses, wobei die Verdrehsicherung durch die an das Einsatzteil angeformte, in die Längsnut des Drückerhalses einfassende Kammerführung bewirkt wird, wobei gleichzeitig in diesem Bereich die Sperrfeder angeordnet ist. Die Einsteckoffnung weist zwischen den Nuten einen größeren Durchmesser auf, so dass aufgrund dieses Freiraumes die An- Ordnung einer einstückig mit dem Einsatzteil ausgebildeten, ausreichend starken Sperrfeder ermöglicht wird. Der in den nutfreien Längenabschnitt der Einsteckoffnung eingreifende und gegen den Boden der sackartigen Einsteckoffnung gerichtete Abschnitt des Einsteckteiles umschließt dabei das freie Ende des Druckerdornes; vermag in diesem Bereich Fertigungs- toleranzen zwischen der Einsteckoffnung und dem Drückerdorn ausgleichen und bildet eine zusätzliche Verdrehsicherung für den Drückerdorn. Die Anordnung der erfindungsgemäßen Türdrückerklemmbefestigung an jeweils beiden gegenüberliegenden Türdrückern eines Türbeschlages ermöglicht durch Auswechseln des Einsatzteiles mit geänderter Durch- gangsöffnung die Anpassung an Drückerdorne unterschiedlichen Durchmessers oder mit unterschiedlichen Einstecköffnungen, so dass die Notwendigkeit einer Anpassung der Einsteckoffnung eines Türdrückers an einen Drückerdorn vorgegebenen Durchmessers entfällt. Dies führt zu einer Vereinheitlichung in der Fertigung der Türdrücker. Beispielsweise können Türdrücker mit einer für einen Drückerdorn mit einem Außendurchmesser von 9 mm bestimmten Einsteckoffnung auf einen Drückerdorn mit einem Außendurchmesser von 8 mm aufgesteckt werden.With the teaching of claim 1, in the area of the longitudinal section of the insertion opening having the grooves, the insert is held in the insert opening of the door handle neck in a manner that is resistant to torsion, compression and rotation, the anti-rotation effect being brought about by the chamber guide molded onto the insert part and engaging in the longitudinal groove of the handle neck is, the locking spring being arranged at the same time in this area. The insertion opening has a larger diameter between the grooves, so that due to this free space the arrangement of a sufficiently strong locking spring formed in one piece with the insert part is made possible. The section of the insertion part which engages in the groove-free length section of the insertion opening and is directed towards the bottom of the sack-like insertion opening encloses the free end of the printer mandrel; is able to compensate for manufacturing tolerances in this area between the insertion opening and the mandrel and forms an additional anti-rotation device for the mandrel. The arrangement of the door handle clamp fastening according to the invention on each of the two opposite door handles of a door fitting enables adaptation to handle pins of different diameters or with different insertion openings by exchanging the insert part, so that there is no need to adapt the opening of a door handle to a handle diameter given. This leads to a Standardization in the manufacture of door handles. For example, door handles with an insertion opening intended for a handle mandrel with an outer diameter of 9 mm can be plugged onto a handle mandrel with an outer diameter of 8 mm.
In Ausgestaltung der Erfindung ist die in die Längsnut der Einsteckoffnung einsteckbare Kammerführung derart ausgeführt, dass sie über eine Außenwand des Einsatzteiles vorsteht, d. h. eine oder mehrere über die Außenwand des Einsatzteiles vorstehende Rippen bildet, die formschlüssig die vorgenannte Längsnut ausfüllen, wobei in bevorzugter Ausführung zwei derartige Kammerführungen vorgesehen sind, die jeweils an gegenüberliegenden Außenwänden des Einsatzteiles angeordnet sind. Dabei kann eine der beiden Kammerführungen länger ausgebildet sein, während die zweite Kammerführung demgegenüber kürzer ausgebildet ist und in die einstückiger Bestandteil der Außenwand bildende Sperrfeder über- geht.In an embodiment of the invention, the chamber guide which can be inserted into the longitudinal groove of the insertion opening is designed in such a way that it protrudes over an outer wall of the insert, i. H. forms one or more ribs projecting over the outer wall of the insert part, which form-fit fill the aforementioned longitudinal groove, two preferred chamber guides being provided in a preferred embodiment, each of which is arranged on opposite outer walls of the insert part. In this case, one of the two chamber guides can be made longer, while the second chamber guide, on the other hand, is shorter and merges into the locking spring forming an integral part of the outer wall.
Nach einem weiteren Merkmal der Erfindung ist an einer Außenwand des Einsatzteiles ein über die Außenwand vorstehender Zentrierungsansatz für die Halteschraube angeordnet; der Zentrierungsansatz fixiert im Zusammenwirken mit der Halteschraube das Einsatzteil in der Einstecköff- nung des Türdrückerhalses und vermag gleichzeitig bei entsprechender Beaufschlagung - zusätzlich zu der Funktion der Sperrfeder - den Drük- kerdorn im Drückerhals zu arretieren.According to a further feature of the invention, a centering projection projecting beyond the outer wall for the retaining screw is arranged on an outer wall of the insert part; the centering lug, in cooperation with the retaining screw, fixes the insert in the insertion opening of the lever handle neck and at the same time, if it is acted upon appropriately - in addition to the function of the locking spring - it can also lock the handle pin in the handle neck.
Die einzelnen Bauelemente der Türdrückerklemmbefestigung einschließlich des Türdrückers, des Druckerdornes sowie der Türdrückerklemmbe- festigung können grundsätzlich aus einem beliebigen geeigneten Werkstoff bestehen; es hat sich jedoch als fertigungstechnisch vorteilhaft und kostengünstig erwiesen, wenn das Einsatzteil aus einem geeigneten Kunststoff besteht. Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles näher erläutert.The individual components of the door handle clamp fastening including the door handle, the printer mandrel and the door handle clamp fastening can basically consist of any suitable material; However, it has proven to be advantageous in terms of production technology and inexpensively if the insert part consists of a suitable plastic. The invention is explained in more detail below using an exemplary embodiment.

Ein Türdrücker 1 gemäß Figur 1 besitzt im Bereich eines Türdrückerhalses 2 eine Einsteckoffnung 3, in die ein Drückerdorn 4 eingesteckt ist. Die Ein- stecköffnung 3 weist über ihre gesamte Länge den gleichen Innendurchmesser auf, wobei im Bereich der Innenwandung der Einsteckoffnung 3 in einem dem Türblatt benachbarten Abschnitt a zwei gegenüberliegende Längsnuten 12 vorgesehen sind. Ein allgemein mit 7 bezeichnetes Einsatzteil (siehe insbesondere Figuren 4 bis 7) besitzt an zwei gegenüber- liegenden Außenwänden 16 und 17 als Kammerführungen 13 bzw. 14 be- zeichnete erhabene Verstärkungen, die in die Längsnuten 12 eingreifen. Es ist ersichtlich, dass die an der Außenwand 16 angeordnete Kammerführung 13 länger ausgebildet ist als die an der Außenwand 17 angeordnete Kammerführung 14. Die Kammerführung 13 endet unter Belassung eines Zwischenraumes 19 in einem Zentrierungsansatz 18, in welchem eine den Türdrückerhals 2 durchfassende Halteschraube 5 einschraubbar ist, so dass die Halteschraube 5 das Einsatzteil 7 im Türdrückerhals 2 arretiert und bei entsprechender Beaufschlagung zusätzlich den die Durchgangsöffnung 6 des Einsatzteiles 7 durchfassenden Drückerdorn 4 arretie- ren kann. Wesentlicher Bestandteil einer allgemein mit 8 bezeichneten Türdrückerklemmbefestigung ist eine im Anschluss an die Kammerführung 4 ausgebildete und Bestandteil des Einsatzteiles 7 bildende Sperrfeder 10, die mit einem an ihrem freien Ende ausgebildeten Rasthaken 11 in eine zugeordnete Rastverzahnung 9 des Druckerdornes 4 eingreift.A door handle 1 according to FIG. 1 has an insertion opening 3 in the area of a door handle neck 2, into which a handle mandrel 4 is inserted. The insertion opening 3 has the same inner diameter over its entire length, two longitudinal grooves 12 lying opposite one another being provided in the area of the inner wall of the insertion opening 3 in a section a adjacent to the door leaf. An insert generally designated 7 (see in particular FIGS. 4 to 7) has on two opposite outer walls 16 and 17 as chamber guides 13 and 14, respectively. drew raised reinforcements which engage in the longitudinal grooves 12. It can be seen that the chamber guide 13 arranged on the outer wall 16 is designed to be longer than the chamber guide 14 arranged on the outer wall 17 is so that the retaining screw 5 locks the insert part 7 in the lever handle neck 2 and, when suitably acted upon, can additionally lock the handle pin 4 which extends through the through opening 6 of the insert part 7. An essential component of a door handle clamp attachment, generally designated 8, is a locking spring 10, which is formed in connection with the chamber guide 4 and forms part of the insert part 7 and which engages in an associated locking toothing 9 of the printer mandrel 4 with a locking hook 11 formed at its free end.
Wie insbesondere die Figuren 1 und 2 ausweisen, sind die Längsnuten 12 in der Einsteckoffnung 3 des Türdrückerhalses 2 nur über den Längenabschnitt a ausgeführt, während das Einsatzteil 7 darüber hinausgehend im Bereich des Längenabschnittes b - d. h. gegen einen Boden 15 der Einsteckoffnung 3 gerichtet - verlängert ausgebildet ist. Hierdurch können Fertigungstoleranzen mit Bezug auf den Drückerdorn 4 oder die Einsteckoffnung 3 über die gesamte Länge der Einsteckoffnung 3 durch entsprechende Anpassung des Einsatzteiles 7 ausgeglichen werden. Die Durch- gangsöffnung 6 des Einsatzteiles 3 kann je nach Erfordernis dem Durchmesser des zur Anwendung gelangenden Druckerdornes 4 angepasst werden. BezugszeichenlisteAs shown in FIGS. 1 and 2 in particular, the longitudinal grooves 12 in the insertion opening 3 of the lever handle neck 2 are designed only over the length section a, while the insert part 7 extends further in the area of the length section b - ie directed towards a bottom 15 of the insertion opening 3 is trained. As a result, manufacturing tolerances with respect to the mandrel 4 or the insertion opening 3 can be compensated for over the entire length of the insertion opening 3 by appropriate adaptation of the insert part 7. The through opening 6 of the insert 3 can be adapted to the diameter of the printer mandrel 4 that is used, depending on requirements. LIST OF REFERENCE NUMBERS
