Definitions
- the invention relates to a securing element for on a panel support of a household appliance pivotally mounted actuators.
- pivotable actuators of a dishwasher e.g. a handle shell cover
- a handle shell cover associated by this Verschwenk institute, e.g. Bolts which engage in bearing elements on the screen carrier, arranged pivotally on the screen carrier, wherein the bolts are secured by mounting in the crimping in their bearing elements after mounting the handle shell cover.
- a disadvantage of this type of fuse is that in this way the pivoting elements and thus the actuators are inseparably connected to the diaphragm support so that in case of service, the entire diaphragm support and not only defective actuators must be replaced.
- An aperture support according to the preamble of the independent claim is already known from the document EP-A-0 960 996.
- an actuating element arranged on the screen carrier of a dishwasher preferably a handle shell cover
- pivoting elements provided for this, e.g. in a bearing element engaging bolt, pivotally mounted on the screen carrier.
- the bolt engages in a bearing element assigned to it, which is arranged on the cover carrier or on the handle shell cover and thereby forms a hinge.
- the hinge allows the pivoting movement of the actuating element, in particular the handle shell cover.
- the pivoting of the handle shell cover is done by manual intervention in these and acts on the unlocking mechanism of the door.
- the securing of the pivoting elements is preferably carried out by a spring element which is arranged in the immediate vicinity of the pivoting elements.
- the spring element essentially assumes a mounting position or a securing position. In the securing position, the spring prevents the unintentional release of the pivoting elements against each other by indirectly or directly serving as a stop at least one of the interlocking pivoting elements. In the mounting position, the spring no longer acts as a stop on the interlocking pivoting elements, thus, for example, the bolt from his.Lagerelement and thus the handle shell cover can be solved by the panel carrier.
- Such a fuse in addition to the re-solubility has the further advantage that over the known solution, the backup function does not have to be introduced in an additional assembly step, so that a cost reduction is achieved.
- the spring element assumes a largely reduced-voltage state in the securing position, which is free of manually applied voltage, certain voltages, e.g. by the adjacent actuator or the adjacent pivoting elements are unavoidable. However, in order to move the spring element from the securing position into the mounting position and thus abandon the stop function of the spring element on pivoting or actuating elements, a force acting on the spring element, e.g. by manually bending this, apply.
- the aforesaid force no longer acts on the spring element in the assembly position, it relaxes and automatically returns to the securing position, provided that it encounters no obstacles, e.g. can arise as a result of the fact that the pivoting elements do not mesh correctly with one another after assembly and so to speak stand in the way of the spring element.
- the entire design parameters of the spring element are designed so that the transfer of the spring from the securing position to the mounting position and vice versa is repeated several times, so that an actuating element can be replaced several times individually or can be repeatedly corrected in its position during the assembly process.
- the bending spring as a leaf spring, coil springs, torsion springs, disc springs and other bending springs, are preferred for the used material plastic, in particular for its processing in injection rather unsuitable, since manufacturing technically complex and expensive to produce.
- the leaf spring has at least one leg, in principle, several legs are conceivable, but these make the production of the spring element with the diaphragm support more complicated and expensive, so that preferably a leaf spring leg is arranged.
- the bend of the leaf spring leg is between the clamping point and its other free tail.
- the stop and thus the contact surface of the spring element to the pivoting elements or pivoting elements receiving portions to arrange the actuator in the vicinity of the bend and not at the clamping, since in this arrangement, not the entire spring leg from the securing position must be bent or pressed into the mounting position, and the recess for receiving the spring leg in the mounting position can be kept correspondingly small.
- the Federelement mit the diaphragm support as already mentioned above in one piece and injection molded from plastic.
- the material used for the spring element can be modified, this being done by reinforcing agents, fillers, auxiliaries, aging hammers and / or stabilizers.
- the handle shell cover is a large-volume actuator with appropriate mass, which is symmetrical with respect to a vertical center line, it makes sense to provide two hinges, which are also symmetrical to each other and through which an axis passes, around which the pivoting movement of the handle shell cover. Since both hinges are spaced from each other, each of these must be secured by a respective spring element to prevent inadvertent release of the handle shell cover by violent manual intervention in this.
- FIG. 1 shows the section of a panel support 1, which is arranged in the upper region of a dishwasher door, on which a handle shell cover 2 is arranged pivotably as an actuating element.
- the handle shell cover 2 has laterally two guide webs 3, each receiving at one end a bolt 4 and these each engage in a provided on the panel support 1 bearing element 5.
- Bolt 4 and bearing elements 5 form in this embodiment, the pivoting elements, which face each other symmetrically to a vertical center line, not shown by the handle shell cover 2. Through the line connecting the centers of both bolts 4, the pivot axis of the handle shell cover 2 extends, wherein the pivoting takes place in the direction of the arrow 14.
- a spring element 6 is arranged in the immediate vicinity of the pivoting elements and in direct contact with the non-visible clamping points of the bolt 4 in the guide webs 3 of the handle shell cover 2 lying in the pivot axis and on both sides of the handle shell cover depending a spring element 6 is arranged.
- the spring elements 6 are in the securing position, wherein this can be seen in the drawing of FIG 1 only on the left spring element 6.
- the spring elements 6 are also designed as a leaf spring 6a, which is shown in Figures 2 and 3 better recognizable.
- the leaf springs 6a are executed with the diaphragm support 1 in one piece.
- the leaf spring 6a has a leaf spring leg 9 with a bend 9a. Due to the bend 9a of the leaf spring leg 9 is spaced from the back of the front facing surface 10 of the diaphragm support 1 different.
- the clamping point 11 of the leaf spring 6a is located on the back of the front facing surface 10 of the diaphragm support 1, seen from here, the bend 9a of the leaf spring leg takes place from the back of the front facing surface 10 of the diaphragm support 1 away.
- a recess 12 is provided such that it receives the leaf spring leg 9 in the mounting position.

Description
Die Erfindung betrifft ein Sicherungselement für an einem Blendenträger eines Haushaltsgerätes verschwenkbar angeordnete Betätigungselemente.The invention relates to a securing element for on a panel support of a household appliance pivotally mounted actuators.
In bekannter Weise werden verschwenkbare Betätigungselemente einer Geschirrspülmaschine, z.B. ein Griffschalendeckel, durch diesen zugeordnete Verschwenkelemente, z.B. Bolzen die in Lagerelemente am Blendenträger greifen, am Blendenträger verschwenkbar angeordnet, wobei die Bolzen nach Montage des Griffschalendeckels durch Verquetschen in ihren Lagerelementen gesichert sind. Nachteilig an dieser Art der Sicherung ist, dass auf diese Weise die Verschwenkelemente und damit die Betätigungselemente mit dem Blendenträger untrennbar verbunden sind, so dass im Servicefall der gesamte Blendenträger und nicht nur defekte Betätigungselemente ausgetauscht werden müssen. Ein Blendenträger gemäß dem Oberbegriff des unabhängigen Anspruchs ist aus dem Dokument EP-A-0 960 996 bereits bekannt.In a known manner pivotable actuators of a dishwasher, e.g. a handle shell cover, associated by this Verschwenkelemente, e.g. Bolts which engage in bearing elements on the screen carrier, arranged pivotally on the screen carrier, wherein the bolts are secured by mounting in the crimping in their bearing elements after mounting the handle shell cover. A disadvantage of this type of fuse is that in this way the pivoting elements and thus the actuators are inseparably connected to the diaphragm support so that in case of service, the entire diaphragm support and not only defective actuators must be replaced. An aperture support according to the preamble of the independent claim is already known from the document EP-A-0 960 996.
Es ist daher Aufgabe der Erfindung, eine Sicherung von den Betätigungselementen zugeordneten Verschwenkelementen vorzusehen, die einfach und kostengünstig aufgebaut ist, wobei die einzelneun Verschwenkelemente derartig gesichert sein sollen, dass im Servicefall deren zugehörige Betätigungselemente einzeln am Blendenträger austauschbar sind.It is therefore an object of the invention to provide a backup of the actuators associated pivoting elements, which is simple and inexpensive, with the einzelun pivoting elements should be secured such that in case of service whose associated actuators are individually interchangeable on the screen carrier.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with the features of claim 1.
Gemäß Anspruch 1 wird ein am Blendenträger einer Geschirrspülmaschine angeordnetes Betätigungselement, vorzugsweise ein Griffschalendeckel, durch für diesen vorgesehene Verschwenkelemente, z.B. in ein Lagerelement eingreifender Bolzen, verschwenkbar am Blendenträger angeordnet. Der Bolzen greift in ein ihm zugeordnetes Lagerelement, welches am Blendenträger oder am Griffschalendeckel angeordnet ist und bildet hierdurch einen Scharnier. Das Scharnier ermöglicht die Verschwenkbewegung des Betätigungselementes, insbesondere die des Griffschalendeckels. Die Verschwenkung des Griffschalendeckels erfolgt durch manuellen Eingriff in diesen und wirkt auf den Entriegelungsmechanismus der Tür ein. Um bei besonders heftigen öder ruckartigen manuellen Eingriff in den Griffschalendeckel zu verhindern, dass die Verschwenkelemente sich gegeneinander lösen, sprich der Bolzen aus seinem Lagerelement herausgerissen wird, sind die beiden Verschwenkelemente gegeneinander gesichert, was erfindungsgemäß in wiederlösbarer Weise erfolgt.In accordance with claim 1, an actuating element arranged on the screen carrier of a dishwasher, preferably a handle shell cover, is provided by pivoting elements provided for this, e.g. in a bearing element engaging bolt, pivotally mounted on the screen carrier. The bolt engages in a bearing element assigned to it, which is arranged on the cover carrier or on the handle shell cover and thereby forms a hinge. The hinge allows the pivoting movement of the actuating element, in particular the handle shell cover. The pivoting of the handle shell cover is done by manual intervention in these and acts on the unlocking mechanism of the door. In order to prevent particularly violent or sudden jerky manual intervention in the handle shell cover that the pivoting elements against each other, that is, the bolt is torn out of its bearing element, the two pivoting elements are secured against each other, which is done according to the invention in a detachable manner.
Die Sicherung der Verschwenkelemente erfolgt vorzugsweise durch ein Federelement welches in unmittelbarer Nähe der Verschwenkelemente angeordnet ist. Das Federelement nimmt im wesentlichen eine Montagestellung oder eine Sicherungsstellung ein. In Sicherungsstellung verhindert die Feder das unbeabsichtigte Lösen der Verschwenkelemente gegeneinander, indem sie zumindest einem der ineinandergreifenden Verschwenkelemente mittelbar oder unmittelbar als Anschlag dient. In der Montagestellung wirkt die Feder nicht mehr als Anschlag auf die ineinandergreifenden Verschwenkelemente, somit kann z.B. der Bolzen aus seinem.Lagerelement und damit der Griffschalendeckel vom Blendenträger gelöst werden. Eine solche Sicherung hat neben der Wiederlösbarkeit den weiteren Vorteil, dass gegenüber der bekannten Lösung die Sicherungsfunktion nicht in einem zusätzlichen Montageschritt eingebracht werden muß, so dass auch eine Kostenreduzierung erreicht ist.The securing of the pivoting elements is preferably carried out by a spring element which is arranged in the immediate vicinity of the pivoting elements. The spring element essentially assumes a mounting position or a securing position. In the securing position, the spring prevents the unintentional release of the pivoting elements against each other by indirectly or directly serving as a stop at least one of the interlocking pivoting elements. In the mounting position, the spring no longer acts as a stop on the interlocking pivoting elements, thus, for example, the bolt from his.Lagerelement and thus the handle shell cover can be solved by the panel carrier. Such a fuse in addition to the re-solubility has the further advantage that over the known solution, the backup function does not have to be introduced in an additional assembly step, so that a cost reduction is achieved.
Das Federelement nimmt in Sicherungsstellung einen weitestgehend spannungsreduzierten Zustand ein, welcher frei von manuell aufgebrachter Spannung ist, gewisse Spannungen, z.B. durch das anliegende Betätigungselement bzw. die anliegenden Verschwenkelemente sind nicht zu vermeiden. Um jedoch das Federelement aus der Sicherungsstellung in die Montagestellung zu versetzen und damit die Anschlagfunktion des Federelementes auf Verschwenk- bzw. Betätigungselemente aufzugeben, ist eine auf das Federeleinent wirkende Kraft, z.B. durch manuelles Biegen dieser, aufzubringen.The spring element assumes a largely reduced-voltage state in the securing position, which is free of manually applied voltage, certain voltages, e.g. by the adjacent actuator or the adjacent pivoting elements are unavoidable. However, in order to move the spring element from the securing position into the mounting position and thus abandon the stop function of the spring element on pivoting or actuating elements, a force acting on the spring element, e.g. by manually bending this, apply.
Wirkt die vorstehend genannte Kraft.nicht mehr auf das Federelement in Montagestellung ein, entspannt sich dieses und setzt sich selbsttätig in die Sicherungsstellung zurück, sofern es auf keine Hindernisse trifft, die z.B. dadurch entstehen können, dass die Verschwenkelemente nach erfolgter Montage nicht richtig ineinander greifen und dem Federelement sozusagen im Weg stehen.If the aforesaid force no longer acts on the spring element in the assembly position, it relaxes and automatically returns to the securing position, provided that it encounters no obstacles, e.g. can arise as a result of the fact that the pivoting elements do not mesh correctly with one another after assembly and so to speak stand in the way of the spring element.
Die gesamten Konstruktionsparameter des Federelementes sind so ausgelegt, dass die Überführung der Feder von der Sicherungsstellung in die Montagestellung und umgekehrt mehrfach wiederholbar ist, so dass ein Betätigungselement mehrfach einzeln ausgetauscht oder während des Montagevorganges mehrfach in seiner Position korrigiert werden kann.The entire design parameters of the spring element are designed so that the transfer of the spring from the securing position to the mounting position and vice versa is repeated several times, so that an actuating element can be replaced several times individually or can be repeatedly corrected in its position during the assembly process.
Um die vorstehend genannten Funktionen des Federelementes ausüben zu können ist zweckmäßiger Weise eine Biegefeder einzusetzen.In order to exercise the above-mentioned functions of the spring element is expedient manner to use a spiral spring.
Es ist besonders kostengünstig und einfach für die Herstellung die Biegelfeder als Blattfeder auszugestalten, Spiralfedern, Drehfedern, Tellerfedern u.a. Biegefedern, sind für das bevorzugt verwendete Material Kunststoff, insbesondere für dessen Verarbeitung im Spritzguß eher ungeeignet, da fertigungstechnisch aufwendiger und teurer herzustellen.It is particularly inexpensive and easy to design for the production of the bending spring as a leaf spring, coil springs, torsion springs, disc springs and other bending springs, are preferred for the used material plastic, in particular for its processing in injection rather unsuitable, since manufacturing technically complex and expensive to produce.
Fertigungstechnisch ist es bezüglich des Aufwandes und der Kosten besonders günstig das Federelement bzw. die Blattfeder mit dem Blendenträger in einem Stück auszuführen. Ausführungen in mehr als einem Stück erfordern z.B. ein Ankleben des Federelementes am Blendenträger oder eine andere Befestigungstechnik und erhöhen dadurch den fertigungstechnischen Aufwand und reduzieren u.U. die Funktionssicherheit des Blendenträgers insgesamt.Manufacturing technology, it is particularly favorable in terms of effort and cost to perform the spring element or the leaf spring with the diaphragm carrier in one piece. Designs in more than one piece require e.g. Sticking of the spring element on the panel support or other fastening technology and thereby increase the manufacturing effort and reduce u.U. the reliability of the panel carrier in total.
Die Blattfeder weist zumindest einen Schenkel auf, prinzipiell sind mehrere Schenkel denkbar, diese machen die Herstellung des Federelementes mit dem Blendenträger jedoch komplizierter und teuerer, so dass vorzugsweise ein Blattfederschenkel angeordnet ist.The leaf spring has at least one leg, in principle, several legs are conceivable, but these make the production of the spring element with the diaphragm support more complicated and expensive, so that preferably a leaf spring leg is arranged.
Als Anschlag und damit als Kontaktfläche zwischen Federelement und Verschwenkelementen oder Verschwenkelemente aufnehmende Teile des Betätigungselementes dient nur eine kleine Teilfläche des Federelementes und zwar vorzugsweise ein Teil des Blattfederschenkels. Um die Kontaktfläche zu vergrößern und infolgedessen die dabei auftretende Spannungen auf das Federelement zu verringern, wird in den Blattfederschenkel eine Abknickung so eingebracht, dass in Sicherungsstellung eine größere Kontaktfläche vorhanden ist.As a stop and thus as a contact surface between the spring element and pivot elements or pivoting elements receiving parts of the actuating element is only a small partial surface of the spring element and that is preferably a part of the leaf spring leg. In order to increase the contact surface and as a result to reduce the resulting stresses on the spring element, a bend is introduced into the leaf spring leg, that in securing position a larger contact surface is present.
Die Abknickung des Blattfederschenkels liegt zwischen dessen Einspannstelle und seinem anderen freien Endstück. Im Hinblick auf eine hohe Funktionssicherheit ist es zweckmäßig, den Anschlag und damit die Kontaktfläche des Federelementes zu den Verschwenkelementen bzw. Verschwenkelemente aufnehmende Teilbereiche des Betätigungselementes in der Nähe der Abknickung und nicht bei der Einspannstelle anzuordnen, da bei dieser Anordnung nicht der gesamte Federschenkel aus der Sicherungsstellung in die Montagestellung gebogen bzw. gedrückt werden muß, und die Aussparung zur Aufnahme des Federschenkels in Montageposition entsprechend klein gehalten werden kann.The bend of the leaf spring leg is between the clamping point and its other free tail. With regard to a high reliability, it is expedient, the stop and thus the contact surface of the spring element to the pivoting elements or pivoting elements receiving portions to arrange the actuator in the vicinity of the bend and not at the clamping, since in this arrangement, not the entire spring leg from the securing position must be bent or pressed into the mounting position, and the recess for receiving the spring leg in the mounting position can be kept correspondingly small.
In einer besonders bevorzugten, weil kostengünstigen und fertigungstechnischen einfachen Ausführungsform, ist das Federelement.mit dem Blendenträger wie bereits obenstehend erwähnt in einem Stück ausgeführt und aus Kunststoff spritzgegossen.In a particularly preferred, because inexpensive and simple production engineering embodiment, the Federelement.mit the diaphragm support as already mentioned above in one piece and injection molded from plastic.
Um die Funktionssicherheit und Langzeitstabilität des Federelementes noch mehr zu erhöhen, kann in einer weiteren Ausführungsform das für das Federelement verwendete Material modifiziert werden, wobei dies durch Verstärkungsstoffe, Füllstoffe, Hilfsstoffe, Alterungshämmer und/oder Stabilisatoren erfolgt.In order to increase the reliability and long-term stability of the spring element even more, in a further embodiment, the material used for the spring element can be modified, this being done by reinforcing agents, fillers, auxiliaries, aging hammers and / or stabilizers.
Da der Griffschalendeckel ein großvolumiges Betätigungselement mit entsprechender Masse ist, welches bezüglich einer vertikalen Mittellinie symmetrisch aufgebaut ist, ist es sinnvoll, zwei Scharniere vorzusehen, die ebenfalls symmetrisch zueinander liegen und durch die eine Achse verläuft, um die die Verschwenkbewegung des Griffschalendeckels erfolgt. Da beide Scharniere voneinander beabstandet sind, muß jedes dieser durch je ein Federelement gesichert werden, um ein unbeabsichtigtes Lösen des Griffschalendeckels durch gewaltsamen manuellen Eingriff in diesen zu verhindern.Since the handle shell cover is a large-volume actuator with appropriate mass, which is symmetrical with respect to a vertical center line, it makes sense to provide two hinges, which are also symmetrical to each other and through which an axis passes, around which the pivoting movement of the handle shell cover. Since both hinges are spaced from each other, each of these must be secured by a respective spring element to prevent inadvertent release of the handle shell cover by violent manual intervention in this.

FIG 1 zeigt den Ausschnitt eines Blendenträgers 1, der im oberen Bereich einer Geschirrspülertür angeordnet ist, an dem als Betätigungselement ein Griffschalendeckel 2 verschwenkbar angeordnet ist. Der Griffschalendeckel 2 weist seitlich zwei Führungsstege 3 auf, die jeweils an einem Ende einen Bolzen 4 aufnehmen und diese jeweils in ein am Blendenträger 1 vorgesehenes Lagerelement 5 eingreifen. Bolzen 4 und Lagerelemente 5 bilden in diesem Ausführungsbeispiel die Verschwenkelemente, welche sich zu einer nicht dargestellten vertikalen Mittellinie durch den Griffschalendeckel 2 einander symmetrisch gegenüberliegen. Durch die Verbindungslinie der Mittelpunkte beider Bolzen 4 verläuft die Verschwenkachse des Griffschalendeckels 2, wobei die Verschwenkung in Richtung des Pfeiles 14 erfolgt. In unmittelbarer Nähe der Verschwenkelemente und im direkten Kontakt auf die nicht sichtbare Einspannstellen des Bolzens 4 in den Führungsstegen 3 des Griffschalendeckels 2 ist in der Verschwenkachse liegend und beidseitig des Griffschalendeckels je ein Federelement 6 angeordnet. Die Federelemente 6 befinden sich in Sicherungsstellung, wobei dies in der zeichnerischen Darstellung von FIG 1 nur am linken Federelement 6 erkennbar ist. Die Federelemente 6 sind zudem als Blattfeder 6a ausgeführt, wobei dies in den Figuren 2 und 3 besser erkennbar dargestellt ist. Die Blattfedern 6a sind mit dem Blendenträger 1 in einem Stück ausgeführt.1 shows the section of a panel support 1, which is arranged in the upper region of a dishwasher door, on which a handle shell cover 2 is arranged pivotably as an actuating element.

FIG 2 zeigt einen Schnitt entlang einer Blattfeder 6a aus FIG 1. Die Blattfeder 6a weist einen Blattfederschenkel 9 mit einer Abknickung 9a auf. Bedingt durch die Abknickung 9a ist der Blattfederschenkel 9 von der Rückseite der vorderen Verblendungsfläche 10 des Blendenträgers 1 unterschiedlich beabstandet. Die Einspannstelle 11 der Blattfeder 6a befindet sich an der Rückseite der vorderen Verblendungsfläche 10 des Blendenträgers 1, von hier aus gesehen erfolgt die Abknickung 9a des Blattfederschenkels von der Rückseite der vorderen Verblendungsfläche 10 des Blendenträgers 1 weg. Zwischen Blattfeder 6a und der Rückseite der vorderen Verblendungsfläche 10 des Blendenträgers 1, umgeben von der Einspannstelle 11 der Blattfeder 6a und dem Blattfederschenkels 9 ist eine Aussparung 12 dergestalt vorgesehen, dass diese den Blattfederschenkel 9 in der Montagestellung aufnimmt. In der gezeigten Sicherungsstellung dient das Endstück des Blattfederschenkels 9a dem den Bolzen 4 (in Fig.1 sichtbar) aufnehmenden Führungssteg 3 als Anschlag und sichert so die Verschwenkelemente, Bolzen 4 und Lagerelement 5, und damit den Griffschalendeckel 2 gegen unbeabsichtigtes.Lösen. Der nicht dargestellte Querschnitt des Blattfederschenkels 9 ist nahezu rechteckig, wobei die kürzere Seite dieses Rechteckes über die Länge des Blattfederschenkels eine Seitenfläche der Blattfeder 6a anspannt, die teilweise den Anschlag und damit die Kontaktfläche zum Führungssteg 3 im Bereich der Abknickung 9a bildet.

Zum Aufrechterhalten der Montagestellung muß auf die Blattfeder 6a weiterhin eine Kraft, dargestellt durch Pfeil 13, ausgeübt werden, denn nach dem Loslassen.setzt sich die Blattfeder 6a sonst selbsttätig in Sicherungsstellung zurück. Die Montagestellung der Blattfeder 6a ermöglicht ein Lösen der Verschwenkelemente, Bolzen 4 (sichtbar in Fig.1) und Lagerelement 5, und damit des Griffschalendeckels 2 vom Blendenträger 1. Der Griffschalendeckel 2 wird zur Montage am Blendenträger 1 zunächst an seinen, die Bolzen 4 aufnehmenden Führungsstegen 3 nach innengedrückt; das Einsetzen der Bolzen 4 in die vorgesehenen Lagerelemente 5 am Blendenträger 1 erfolgt bei heruntergedrückter Blattfeder 6a in Montagestellung, sitzen die Bolzen 4 passend in ihren Lagerelementen 5 können die Führungsstege 3 und die Blattfedern 6a losgelassen werden und die Blattfedern 6a bewegen sich selbsttätig in Sicherungsstellung.3 shows a section as in FIG 2, wherein the
Das Federelement 6 bzw. 6a kann Materialmodifikationen in Form von Verstärkungsstoffen und/oder Stabilisatoren und/oder Hilfsstoffen und/oder Zuschlagsstoffen und/oder Alterungshämmern aufweisen, die mit allen übrigen ausgelegten Konstruktionsparametern eine noch bessere langfristige Funktionsstabilität und Funktionssicherheit des Federelementes 6 bzw. 6a gewährleisten. Ohne Darstellung eines weiteren Ausführungsbeispiels und ohne die Erfindung zu beschränken ist denkbar, dass die Bolzen 4 am Blendenträger 1 und die Lagerelemente 5 am Griffschalendeckel 2 angeordnet sind bzw. die Richtung des Ineinanderfügens der Verschwenkelemente anders gewählt ist, die Feder 6 bzw. 6a ist in diesen Fällen auch als Anschlag anzuordnen, wobei die Anordnung so zu wählen ist, dass sie ein Lösen der Verschwenkelemente, die einteilig oder mehrteilig ausgestattet sein können, verhindert. Ferner ist denkbar, dass durch andere als die genannten Verschwenkelemente (Bolzen 4, Lagerelement 5) irgendein Betätigungselement verschwenkbar am Blendenträger 1 ankoppelt und dieses durch zumindest ein Federelement 6 bzw. 6a gesichert ist.The
