Description

Gegenstand der Erfindung ist eine Handhabe zur Bedienung von Fenstern, Türen od. dgl. mit einer Befestigungsplatte, insbesondere einer Lagerrosette, und einem von dieser getragenen, vorzugsweise drehbar gehaltenen, Bedienungsgriff, wobei die Befestigungsplatte bzw. Lagerrosette einen Grundkörper aufweist, der über ihn durchdringende Schrauben od. dgl., vornehmlich am Flügel des Fensters, der Tür od. dgl. befestigbar ist, und wobei dieser Grundkörper stirnseitig eine um die Achse eines Bedienungsgriff-Halses drehbewegliche Abdeckplatte für die Befestigungsschrauben od. dgl. trägt, welche durch zwischen ihr und einer Widerlagerfläche des Bedienungsgriff-Halses angeordnete Federelemente mittels Arretiergliedern an Rastmitteln des Grundkörpers drehsicher fixierbar ist.The invention relates to a handle for operating windows, doors or the like. With a fastening plate, in particular a bearing rosette, and an operating handle, preferably rotatably held by the latter, wherein the fastening plate or bearing rosette has a base body that penetrates through it Screws or the like, mainly on the wing of the window, the door or the like. Can be fastened, and wherein this base body carries a cover plate for the fastening screws or the like which can be rotated around the axis of an operating handle neck and which through which between it and an abutment surface of the operating handle neck arranged spring elements can be fixed by means of locking members on locking means of the base body.

Handhaben dieser Gattung zur Bedienung von Fenstern, Türen od. dgl. sind in vielen verschiedenen Bauarten bekannt, wie beispielsweise durch die DE-PS 26 08 292 sowie die darin in Betracht gezogenen, weiteren Dokumente belegt wird.Handling of this type for the operation of windows, doors or the like are known in many different designs, as evidenced for example by DE-PS 26 08 292 and the other documents considered therein.

Bei der Handhabe nach DE-PS 26 08 292 werden die Federelemente zur drehsicheren Fixierung der Abdeckplatte in ihrer Abdeckstellung vor der Stirnseite des Grundkörpers durch in Aussparungen des letzteren liegende und einstückig mit dem Grundkörper ausgeformte Arretierstege gebildet, die in ihrer entspannten Stellung über die Stirnseite des Grundkörpers vorstehen und federelastisch in rückseitige Vertiefungen der Abdeckplatte einrasten, wenn sich diese in ihrer Abdeckstellung befindet.In the handle according to DE-PS 26 08 292, the spring elements for the rotationally secure fixing of the cover plate in its covering position in front of the end face of the base body are formed by locking webs lying in recesses of the latter and integrally formed with the base body, which in their relaxed position over the end face of the Project the main body and snap into the recesses on the back of the cover plate when it is in its cover position.

Die einstückige Ausformung der federnd nachgiebigen Arretierstege am Grundkörper setzt voraus, daß dieser entweder insgesamt oder aber doch weitestgehend aus einem entsprechend elastischen Kunststoffmaterial gefertigt werden muß, sich also nicht ohne weiteres aus einem metallischen Material herstellen läßt. Letzteres wird aber insbesondere dann gefordert, wenn es sich bei den Handhaben zur Bedienung von Fenstern, Türen od. dgl. um Bedienungselemente für die Betätigung von Treibstangenbeschlägen handelt, bei denen in einer Lagerrosette ein drehbarer Bedienungsgriff sitzt, der mit einem Antriebsdorn in ein Drehantriebsglied des Betätigungsgetriebes für den Treibstangenbeschlag eingreift.The one-piece design of the resilient locking webs on the base body presupposes that it must either be made entirely or at least largely from a correspondingly elastic plastic material, so it cannot be easily produced from a metallic material. The latter is particularly required, however, if the handles for operating windows, doors or the like are control elements for the actuation of espagnolette fittings, in which a rotatable control handle is seated in a bearing rose, which is driven by a drive pin into a rotary drive member of the Actuating gear engages for the connecting rod fitting.

Abgesehen davon, daß durch die drehbare Lagerung eines Bedienungsgriffes in der Lagerrosette auf diese beträchtliche Bedienungskräfte zur Einwirkung gelangen, wird heute auch regelmäßig eine einbruchhemmende Auslegung solcher Handhaben gefordert, indem nämlich der Bedienungsgriff der Lagerrosette in der Verschluß-Schaltstellung des Treibstangenbeschlages über ein Schloß verriegelbar sein muß. Die wünschenswerte Sicherungswirkung durch das Schloß läßt sich in solchen Fällen aber nur erreichen, wenn die Lagerrosette für den Bedienungsgriff zumindest weitestgehend aus einem metallischen Werkstoff bestehtIn addition to the fact that the rotatable mounting of an operating handle in the bearing escutcheon affects this considerable operating force, a burglar-resistant design of such operations is also regularly required today, namely that the operating handle of the bearing escutcheon can be locked via a lock in the closed switch position of the connecting rod fitting got to. The desirable securing effect by the lock can only be achieved in such cases if the bearing rosette for the operating handle consists at least largely of a metallic material

Nachteilig bei der Handhabe nach der DE-PS 26 08 292 wirkt sich aberauch aus, daß dort die Abdeckplatte durch die federelastischen Arretierstege in Richtung von der Stirnseite des Grundkörpers weg unter Vorspannung gesetzt wird, so daß die Abdeckplatte in ihrer Grundstellung mit ihrer Rückseite einen Spaltabstand von der Stirnseite des Grundkörpers einnimmt.A disadvantage of the handle according to DE-PS 26 08 292 also has the effect that there the cover plate is set under tension by the spring-elastic locking webs in the direction away from the end face of the base body, so that the cover plate in its basic position with its back a gap distance occupies from the front of the base body.

Dieser Spaltabstand beeinträchtigt aber die Ästhetik der Handhabe beträchtlich.However, this gap distance significantly affects the aesthetics of the handle.

Bei anderen bekannten Handhaben der gattungsgemäßen Art, z.B. nach DE-OS 22 16 132, wird die drehsichere Fixierung derAbdeckplatte in ihrerAbdeckstellung am Grundkörper durch Federelemente bewirkt, welche zwischen der Widerlagerfläche am Bedienungsgriff-Hals und der Oberseite der Abdeckplatte eingebaut sind.In other known handles of the generic type, e.g. according to DE-OS 22 16 132, the rotationally secure fixing of the cover plate in its cover position on the base body is brought about by spring elements which are installed between the abutment surface on the operating handle neck and the top of the cover plate.

Abgesehen davon, daß es sich bei den hierverwendeten Federelementen um Zusatzteile handelt, die beim Zusammenbau von Bedienungsgriff, Grundkörper und Abdeckplatte ordnungsgemäß eingebaut werden müssen, ist es notwendig, zwischen der Außenseite der Abdeckplatte und der dieser zugewendeten Widerlagerfläche des Bedienungsgriff-Halses einen Spaltabstand vorzusehen, der um den für das Abheben der Abdeckplatte vom Grundkörper notwendigen Federweg größer ist, als die Einbauhöhe des vollständig gespannten Federelementes selbst. Auch hier wird also die Ästhetik der Handhabe beeinträchtigt, wenn das Federelement nicht in einer halsartigen Verlängerung des Grundkörpers verdeckt aufgenommen werden kann oder sich sich von einer zusätzlich auf gesteckten Manschette überdecken läßt.In addition to the fact that the spring elements used here are additional parts that must be properly installed when assembling the operating handle, base body and cover plate, it is necessary to provide a gap between the outside of the cover plate and the abutment surface of the control handle neck facing it, which is greater by the spring travel required for lifting the cover plate from the base body than the installation height of the fully tensioned spring element itself. Here too, the aesthetics of the handle are impaired if the spring element cannot be accommodated or hidden in a neck-like extension of the base body can be covered by an additional cuff.

Der Erfindung liegt die Aufgabe zugrunde, eine Handhabe zur Bedienung- von Fenstern, Türen od. dgl. der eingangs spezifizierten Gattung anzugeben, die auf einfache Art und Weise und ohne zusätzlich einzubauende Federelemente eine selbsttätige. drehsichere Fixierung der Abdeckplatte in ihrer Abdeckstellung vor der Stirnseite des Grundkörpers gewährleistet.The invention is based on the object of specifying a handle for operating windows, doors or the like. Of the type specified at the outset, which is automatic in a simple manner and without additional spring elements to be installed. Guaranteed non-rotatable fixing of the cover plate in its cover position in front of the face of the base body.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß an der aus einem federharten Werkstoff, z.B. Kunststoff oder Metall, bestehenden Abdeckplatte die Federelemente von unmittelbar aus deren Ebene hochgestellten und mindestens mit ihren freien Enden unter Vorspannung an der Widerlagerfläche des Bedienungsgriff-Halses anliegenden, zungenförmigen Materialabschnitten gebildet sind und dabei mehrere Federzungen in gleichmäßigem Winkelabstand zueinander um die Achse des Bedienungsgriff-Halses verteilt an der Abdeckplatte ausgebildet sind.To achieve this object, the invention provides that on the made of a spring-hard material, e.g. Plastic or metal, existing cover plate, the spring elements are formed directly from their level and at least with their free ends under tension against the abutment surface of the control handle neck, tongue-shaped material sections are formed and thereby several spring tongues at a uniform angular distance from each other about the axis of the control handle neck are distributed on the cover plate.

Auch in der an der Stirnseite des Grundkörpers fixierten Lage der Abdeckplatte überbrücken hier die Federzungen den Spaltabstand zwischen dieser und der Widerlagerfläche des Bedienungsgriff-Halses zumindest weitestgehend.Even in the position of the cover plate fixed to the end face of the base body, the spring tongues at least largely bridge the gap distance between the cover plate and the abutment surface of the operating handle neck.

Vorteilhaft bei dieser erfindungsgemäßen Auslegung ist, daß sich die Abdeckplatte relativ dünnwandig ausführen und dabei einstückig mit Federelementen ausstatten läßt, denen eine genügend starke Federwirkung innewohnt, um die Abdeckstellung der Abdeckplatte an der Stirnseite des Grundkörpers zu fixieren.An advantage of this design according to the invention is that the cover plate is relatively thin-walled run and can be equipped in one piece with spring elements, which have a sufficiently strong spring action to fix the cover position of the cover plate on the front side of the base body.

Da sich die Abdeckplatte sowohl im Spritzgußverfahren aus federhartem Kunststoffmaterial als auch durch einen Stanz-Prägevorgang aus federhartem Blech problemlos und mit geringem Aufstand herstellen läßt, ergibt sich eine einfach zusammenzubauende und sicher wirkende Auslegung für die Handhabe.Since the cover plate can be produced from spring-hard plastic material both by injection molding and by means of a stamping and embossing process from spring-hard sheet metal without any problems and with little rebound, this results in an easy-to-assemble and safe-acting design for the handle.

Eine drehsichere Fixierlage der Abdeckplatte läßt sich erfindungsgemäß dadurch sicherstellen, daß die freie Länge jedes als Federzunge wirkenden Materialabschnittes auf die Breite der Widerlagerfläche am abgewinkelten Schaftabschnitt des Bedienungsgriffs abgestimmt ist.A rotationally secure fixing position of the cover plate can be ensured according to the invention in that the free length of each material section acting as a spring tongue is matched to the width of the abutment surface on the angled shaft section of the operating handle.

Es hat sich nach der Erfindung aber auch als nachahmenswert erwiesen, wenn die freien Enden der Federzungen jeweils einen Teil der Umfangsränder eines den Bedienungsgriff-Hals unterhalb seiner Widerlagerfläche umfassenden Rundloches In der Abdeckplatte bilden. Hierdurch wird das Bewegungsspiel zwischen dem Bedienungsgriff-Hals bzw. einer Lagertülle hierfür und dem davon durchragten Rundloch in der Abdeckplatte auf ein Mindestmaß eingeengt.According to the invention, however, it has also proven to be worth copying if the free ends of the spring tongues each form part of the circumferential edges of a round hole in the cover plate comprising the control handle neck below its abutment surface. As a result, the movement between the operating handle neck or a bearing sleeve for this and the round hole protruding therefrom in the cover plate is reduced to a minimum.

Bewährt hat es sich nach der Erfindung aber auch noch, daß die freie Länge jeder Federzunge auf die Breite der Widerlagerfläche am Bedienungsgriff-Hals abgestimmt ist, Insbesondere wenn die Längskanten der Federzungen jeweils einen Spaltabstand von den ihnen benachbarten Kanten der Spalteinschnitte in der Abdeckplatte aufweisen.It has also proven itself according to the invention that the free length of each spring tongue is matched to the width of the abutment surface on the operating handle neck, in particular if the longitudinal edges of the spring tongues each have a gap distance from the adjacent edges of the gap incisions in the cover plate.

Die geschlossenen Enden der Spalteinschnitte fallen dann nämlich mit der äußeren Umgrenzung des Bedienungsgriff-Halses zusammen und sind deshalb von außen nicht ohne weiteres sichtbar.The closed ends of the gaps then coincide with the outer boundary of the operating handle neck and are therefore not readily visible from the outside.

Das in den Fig. 1 und 2 der Zeichnung dargestellte Ausführungsbeispiel einer Bedienungshandhabe 1 für Fenster, Türen od. dgl. weist als Hauptbestandteil eine Befestigungsplatte bzw. Lagerrosette 2 und den an bzw. in dieser gehaltenen Bedienungsgriff 23 auf.The exemplary embodiment of an operating handle 1 for windows, doors or the like shown in FIGS. 1 and 2 of the drawing has as its main component a fastening plate or bearing rosette 2 and the operating handle 23 held on or in this.

Die Befestigungsplatte bzw. Lagerrosette 2 hat dabei wiederum einen Grundkörper 3 und eine dessen Stirnseite zugeordnete Abdeckplatte 4.The fastening plate or bearing rosette 2 in turn has a base body 3 and a cover plate 4 assigned to its end face.

Über den Grundkörper 3 der Befestigungsplatte bzw. Lagerrosette 2 läßt sich die Handhabe 1 insbesondere an dem öffenbaren Flügel 5 des Fensters oder der Tür befestigen, und zwar mit Hilfe von - nicht dargestellten - Schrauben, welche jeweils durch ein Loch 6 des Grundkörpers 3 hindurchgeführt sind. Konzentrisch zu jedem Loch 6 im Grundkörper 3 ragt von dessen Rückseite ein Nocken oder Dorn 7 ab, welcher zur formschlüssen Drehsicherung des Grundkörpers 3 der Befestigungsplatte 2 am Flügel 5 jeweils in eine stirnseitig offene Bohrung 8 des letzteren eingreift, wie das deutlich in Fig. 1 zu sehen ist.About the base body 3 of the mounting plate or rosette 2, the handle 1 can be attached in particular to the openable wing 5 of the window or the door, with the help of - not shown - screws, which are each passed through a hole 6 of the base body 3 . Concentrically to each hole 6 in the base body 3, a cam or mandrel 7 protrudes from the rear side thereof, which engages in a frontally open bore 8 of the latter for locking the base body 3 of the fastening plate 2 on the wing 5 in a positive manner, as clearly shown in FIG. 1 you can see.

Der Bedienungsgriff 23 weist einen gegenüber dem eigentlichen Griffschaft 9 gegen die Befestigungsplatte bzw. Lagerrosette 2 hin abgewinkelten Schaftabschnitt 10 auf, an den sich einstückig ein Lagerhals 11 anschließt, und zwar unter Bildung einer der Befestigungsplatte bzw. Lagerrosette 2 zugewendeten Widerlagerfläche 12. Der Lagerhals 11 am freien Ende des Schaftabschnitts 10 durchgreift eine Lagerbuchse 13, die von der Rückseite des Grundkörpers 3 durch das Zentralloch 14 einer einstückig mit dem Grundkörper 3 ausgeführten und von dessen Stirnseite abstehenden Lagertülle 15 hindurchgeführt ist. Mit einem Stützbund 16 liegt dabei die Lagerbuchse 13 in einer Vertiefung an der Rückseite des Grundkörpers 3 stützend an, während der Lagerhals 11 des Bedienungsgriffs 23, beispielsweise durch eine Bördelung oder Stauchung 17, axial unverschiebbar gegen den Stützbund 16 der Lagerbuchse 13 festgelegt ist.The operating handle 23 has a shaft section 10 which is angled with respect to the actual handle shaft 9 against the fastening plate or bearing rosette 2 and to which a bearing neck 11 connects in one piece, to form an abutment surface 12 facing the fastening plate or bearing rosette 2. The bearing neck 11 At the free end of the shaft section 10, a bearing bush 13 passes through, which is guided from the rear of the base body 3 through the central hole 14 of a bearing sleeve 15 which is made in one piece with the base body 3 and protrudes from the end face thereof. With a support collar 16, the bearing bush 13 rests in a recess on the back of the base body 3, while the bearing neck 11 of the operating handle 23 is fixed axially immovably against the support collar 16 of the bearing bush 13, for example by flanging or compression 17.

Lagerrosette 2 bzw. aus deren Grundkörper 3 ragt ein Antriebsdorn 18 heraus, der in Achsfluchtlage mit dem Lagerhals 11 drehfest im abgewinkelten Schaftabschnitt 10 des Bedienungsgriffs 23 fixiert ist.A drive mandrel 18 protrudes from the back of the mounting plate or bearing rosette 2 or from its base body 3, which is fixed in the axial alignment with the bearing neck 11 in the angled shaft section 10 of the operating handle 23 in a rotationally fixed manner.

Die Abdeckplatte 4 der Befestigungsplatte bzw. Lagerrosette 2 ist vorgesehen, um die an der Stirnseite des Grundkörpers 3 jeweils mit einem Versenk ausmündenden Löcher 6 zur Aufnahme der Befestigungsschrauben bei am Fenster bzw. an der Tür angebrachter Handhabe 1 abdecken zu können, sobald in diese die Befestigungsschrauben zur Halterung des Grundkörpers 3 am Flügel 5 in der üblichen Weise eingesetzt worden sind.The cover plate 4 of the mounting plate or bearing rosette 2 is provided in order to be able to cover the holes 6 opening on the front side of the base body 3 with a countersink for receiving the fastening screws when the handle 1 is attached to the window or the door, as soon as the latter Fastening screws for holding the base body 3 on the wing 5 used in the usual way have been.

Die Abdeckplatte 4 ist zu diesem Zweck konzentrisch zur Längsachse des Bedienungsgriffs 3 verdrehbar auf der Lagertülle 15 des Grundkörpers 3 angeordnet, und zwar weist sie zu diesem Zweck ein auf den Durchmesser der Lagertülle 15 abgestimmtes Rundloch 19 auf, das insbesondere in den Fig. 3 und 4 zu sehen ist.For this purpose, the cover plate 4 is rotatably arranged concentrically to the longitudinal axis of the operating handle 3 on the bearing bush 15 of the base body 3, specifically for this purpose it has a round hole 19 which is matched to the diameter of the bearing bush 15 and which is particularly evident in FIGS 4 can be seen.

Die Abdeckplatte 4 ist in ihrer Umrißform auf die Umrißform des Grundkörpers 3 abgestimmt und wird aus einem federhartem Werkstoff, z.B. Kunststoff oder Metall, hergestellt. Die Fertigung der Abdeckplatte 4 aus federhartem Kunststoff ist durch Spritzgießen in einer Form möglich. Hingegen läßt sich die Abdeckplatte 4 aus federhartem Metall relativ einfach durch einen Stanz-Prägevorgang bilden.The outline of the cover plate 4 is matched to the outline shape of the base body 3 and is made of a spring-hard material, e.g. Plastic or metal. The cover plate 4 can be made from spring-hard plastic by injection molding in a mold. On the other hand, the cover plate 4 made of spring-hard metal can be formed relatively easily by a stamping and embossing process.

Die drehsichere Fixierung der Abdeckplatte 4 gegenüber dem Grundkörper 3 in der die Durchgangslöcher 6 bzw. die in deren Versenken aufgenommenen Schraubenköpfe abdeckenden Drehstellung kann z.B. über einen umlaufenden Randbord 20 an der Rückseite der Abdeckplatte 4 erfolgen, welcher mit einem entsprechend abgesetzten, beispielsweise angeschrägten, Umfangsrand 21 des Grundkörpers 3 in Formschlußeingriff tritt.The rotationally secure fixing of the cover plate 4 with respect to the base body 3 in the rotary position covering the through holes 6 or the screw heads accommodated in their countersinking can e.g. via a peripheral rim 20 on the back of the cover plate 4, which comes into positive engagement with a correspondingly offset, for example bevelled, peripheral edge 21 of the base body 3.

Zwecks selbsttätiger Herstellung dieses Forrnschlußeingriffs zwischen dem Randbord 20 derAbdeckplatte 4 und dem abgesetzten Umfangsrand 21 des Grundkörpers 3 ist die aus dem federharten Werkstoff bestehende Abdeckplatte 4 im Randbereich ihres Rundloches 19 mit zungenförmig unmittelbar aus ihrer Ebene schräg hochgestellten Materialabschnitten 22 ausgestattet, von denen jeder ein Federelement bildet bzw. als solches wirksam ist. Dabei stützt sich jeder zungenförmige Materialabschnitt 22 mindestens mit seinem freien Ende unter Vorspannung an der Widerlagerfläche 12 ab, welche den Übergang zwischen dem abgewinkelten Schaftabschnitt 10 des Bedienungsgriffes 23 und dessen Lagerhals 11 bildet.For the purpose of automatic production of this connection engagement between the edge 20 of the cover plate 4 and the stepped peripheral edge 21 of the base body 3, the cover plate 4 made of the spring-hard material is provided in the edge region of its round hole 19 with tongue-like material sections 22, each of which is provided with a spring element forms or is effective as such. Each tongue-shaped material section 22 is supported at least with its free end under pretension on the abutment surface 12, which forms the transition between the angled shaft section 10 of the operating handle 23 and its bearing neck 11.

Die die Federelemente bildenden und zungenförmig - z.B. schräg - aus der Ebene derAbdeckplatte 4 hochgestellten Materialabschnitte 22 haben dabei eine solche Formgebung bzw. Federwirkung, daß sie in jedem Falle den rückwärts gerichteten Randbord 20 der Abdeckplatte 4 mit dem Umfangsrand 21 des Grundkörpers 3 in drehsicheren Fixiereingriff drücken, sobald die Abdeckplatte 4 in ihrer Umrißform exakte Deckungslage mit der Umrißform des Grundkörpers 3 einnimmt. Andererseits ist der Abstand zwischen der Widerlagerfläche 12 am abgewinkelten Schaftabschnitt 10 des Bedienungsgriffs 23 und der Stirnfläche der Abdeckplatte 4 bei ihrer Fixierlage am Grundkörper 3 so groß gewählt, daß sich die Abdeckplatte 4 von Hand entgegen der Federwirkung der zungenförmigen Materialabschnitte 22 anheben läßt, und zwar so weit, daß ihr Randbord 20 mit dem Umfangsrand 21 des Grundkörpers 3 außer Eingriff gelangt. Nunmehr kann die Abdeckplatte 4 um die Lagertülle 15 des Grundkörpers 3 aus der Abdeckstellung nach Fig. 1 soweit - um 90° - verdreht werden, daß die Versenke der Durchgangslöcher 6 und damit die Senkköpfe der Befesfigungsschrauben freigelegt werden, wie das die Fig. 2 zeigt. Dadurch sind die Schraubenköpfe für die Betätigung mit einem Schraubendreher zugänglich.The tongue elements forming the spring elements - e.g. diagonally - from the plane of the cover plate 4 material sections 22 have such a shape or spring action that in any case they press the rear-facing rim 20 of the cover plate 4 with the peripheral edge 21 of the base body 3 into rotationally secure fixing engagement as soon as the cover plate 4 is in its Contour shape occupies the exact cover position with the outline shape of the base body 3. On the other hand, the distance between the abutment surface 12 on the angled shaft section 10 of the operating handle 23 and the end face of the cover plate 4 is chosen so large in its fixing position on the base body 3 that the cover plate 4 can be lifted by hand against the spring action of the tongue-shaped material sections 22, specifically so far that its rim 20 comes out of engagement with the peripheral edge 21 of the base body 3. Now the cover plate 4 can be rotated around the bearing grommet 15 of the base body 3 from the cover position according to FIG. 1 - by 90 ° - so that the recesses of the through holes 6 and thus the countersunk heads of the fastening screws are exposed, as shown in FIG. 2 . This means that the screw heads are accessible for operation with a screwdriver.

Aus den Fig. 3 und 4 der Zeichnung ist ersichtlich, daß mehrere als Federzungen wirkende Materialabschnitte 22 in gleichmäßigem Winkelabstand zueinander um die Achse der Lagertülle 15 des Grundkörpers 3 bzw. des Halses 11 am Bedienungsgriff 23 verteilt an der Abdeckplatte 4 ausgebildet sind. Erkennbar ist dort auch, daß die freien Enden der als Federzungen dienenden Materialabschnitte 22 jeweils einen Teil der Umfangsränder des die Lagertülle 15 unterhalb der Widerlagerfläche 21 umfassenden Rundloches 19 in der Abdeckplatte 4 bilden.3 and 4 of the drawing it can be seen that a plurality of material sections 22 acting as spring tongues are formed at a uniform angular distance from one another around the axis of the bearing bush 15 of the base body 3 or neck 11 on the operating handle 23 on the cover plate 4. It can also be seen there that the free ends of the material sections 22 serving as spring tongues each form part of the circumferential edges of the round hole 19 in the cover plate 4 comprising the bearing sleeve 15 below the abutment surface 21.

Die freie Länge jedes als Federzunge wirkenden Materialabschnittes 22 sollte dabei auf die Breite der WP derlagerfläche 12 am abgewinkelten Schaftabschnitt 10 des Bedienungsgriffs 23 abgestimmt sein, wobei die Materialabschnitte 22 eine solche Formgebung haben, daß sie in der drehsicheren Fixierlage der Abdeckplatte 4 den Spaltabstand zwischen deren Stirnfläche sowie der Widerlagerfläche 12 weitestgehend überbrücken.The free length of each material section 22 acting as a spring tongue should be matched to the width of the bearing surface 12 at the angled shaft section 10 of the operating handle 23, the material sections 22 having such a shape that they have the gap distance between them in the rotationally secure fixing position of the cover plate 4 Bridge the end face and the abutment face 12 as far as possible.

Die beste Wirkungsweise der als Federzungen dienenden Materialabschnitte 22 ergibt sich, wenn deren Längskanten jeweils mit einem Spaltabstand 24 von den ihnen benachbarten Kanten von Spalteinschnitten 25 aufweisen.The best mode of operation of the material sections 22 serving as spring tongues results if their longitudinal edges each have a gap distance 24 from the adjacent edges of gap cuts 25.

Ein Vergleich der Fig. 3 und 4 macht deutlich, daß die jeweils in das Rundloch 19 der Abdeckplatte 4 ausmündenden Spalteinschnitte 25 eine unterschiedliche Lage zueinander erhalten können, so daß auch die als Federzungen wirksamen Materialabschnitte 22 eine entsprechend unterschiedliche Umrißform aufweisen.A comparison of FIGS. 3 and 4 makes it clear that the gaps 25 opening out into the round hole 19 of the cover plate 4 can have a different position relative to one another, so that the material sections 22 acting as spring tongues also have a correspondingly different outline shape.

Die als Federzungen wirksamen Materialabschnitte 22 brauchen nicht notwendigerweise mit ihren freien Enden bis an den Begrenzungsrand des Rundloches 19 heranzureichen. Sie können vielmehr auch einen Abstand hiervon haben, so daß der Lochrand ununterbrochen durchläuft. In diesem Falle werden dann die Ränder der als Federzungen wirksamen Materialabschnitte 22 durch einen etwa U-förmig oder auch trapezförmig verlaufenden Schlitz begrenzt, wie das in Fig. 4 durch strichpunktierte Linien angedeutet ist.The material sections 22 acting as spring tongues do not necessarily have to reach with their free ends up to the boundary edge of the round hole 19. You can also have a distance from it so that the edge of the hole runs continuously. In this case, the edges of the material sections 22 which act as spring tongues are then delimited by an approximately U-shaped or trapezoidal slot, as is indicated in FIG. 4 by dash-dotted lines.
