Es ist ein Auflagerelement einer Sitz- oder Liegemöbelunterfederung bekannt,
Aufgabe der Erfindung ist es, ein Auflagerelement zur Verfügung zu stellen, welches in einer unbeschränkten Federstellung einer Härteverstellvorrichtung unabhängig von der Art der Härteverstellung verbessert funktioniert, ebenso wie eine neue effektive Art einer Härteverstellung zur Verfügung gestellt werden soll.The object of the invention is to provide a support element which works in an unrestrained spring position of a hardness adjustment regardless of the type of hardness adjustment works, as well as a new effective way of hardness adjustment should be provided.
Die Lösung dieser Aufgabe erfolgt in Verbindung mit den Merkmalen des Oberbegriffes des ersten Schutzanspruches erfindungsgemäß zusammen mit den technischen Merkmalen dessen kennzeichnenden Teils insbesondere dadurch, dass sich von den den Haltearmen abgewandten Seiten der Lagerschalen Fortsätze in Richtung der Auflagerplatte nach oben erstrecken und in der Auflagerplatte Härteversteller beweglich gelagert sind, die in einer Hartverstellung in Bewegungsrichtung eines Fortsatzes bei Belastung des Auflagerelementes vor einen Fortsatz bewegt sind und so dessen Bewegung um die Drehachse behindern, wobei die Härteversteller in einer uneingeschränkten Federstellung des Auflagerelements neben den Fortsatz bewegt sind und eine freie Drehung der Lagerschalen um deren Drehachsen gestatten, wie dies auch ohne montierte Härteverstellvorrichtung der Fall wäre.The solution of this object is achieved in conjunction with the features of the preamble of the first protection claim according to the invention the technical features of the characterizing part in particular by the fact that extend from the holding arms facing away from the bearing extensions in the direction of the support plate upwards and are movably mounted in the support plate hardness adjuster in a hard adjustment in the direction of movement of an extension under load of the support element in front of a Extension are moved, thus hindering its movement about the axis of rotation, wherein the hardness adjuster are moved in an unrestrained spring position of the support element next to the extension and allow free rotation of the bearing shells about their axes of rotation, as would be the case without mounted hardness adjustment.
Diese erfinderische Lösung erlaubt so eine vollkommene Trennung zwischen der Funktion der Tragarme mit ihren Lagerschalen zur elastischen Abstützung der Auflagerplatte und der Funktion einer Härteverstellung, die nur bei Bedarf die Federrate des Auflagerelementes verhärtet, in dem nur dann die elastischen Verformungen der Tragarme im Bereich der Lagerschalen behindert werden.This innovative solution allows a perfect separation between the function of the support arms with their bearings for elastic support of the support plate and the function of a hardness adjustment, which hardens only when needed, the spring rate of the support element, in which only the elastic deformations of the support arms in the bearing shells be hampered.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich aus und in Kombination mit den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject matter of the invention will become apparent from and in combination with the following subclaims.
Die sich von den Tragarmen von deren oberen Enden nach außen und unten abgewinkelten kurzen Hebearme weisen dabei bevorzugt Winkel von 90° zu den Tragarmen auf, wobei sich die nach oben erstreckenden Fortsätze bei einer Belastung des Auflagerelementes um die unter der oberen Auflagerplatte angeordneten Drehachsen herum nach außen bewegen und diese Bewegung bei einer Hartverstellung des Auflagerelementes von den Härteverstellern behindert wird, sodass die Tragarme stärker auf Biegung beansprucht werden.The angled from the support arms of the upper ends thereof outwardly and down short lift arms preferably have angles of 90 ° to the support arms, wherein the upwardly extending projections at a load of the support element to the arranged under the upper support plate axes of rotation around move outside and this movement is hindered in a hard adjustment of the support element of the hardness adjusters, so that the support arms are subjected to greater bending.
Vorteilhafterweise sind die Drehachsen beidseitig in Lagerböcken beabstandet unter der Auflagerplatte gehalten, die einteilig mit den Lagerböcken als Spritzgussteil hergestellt ist, ebenso wie das Tragelement mit seinem Fußteil und den sich davon nach außen und schräg nach oben abgewinkelt erstreckenden Tragarmen mit den sich daran anschließenden Lagerschalen als einteiliges Spritzgussteil ausgebildet ist.Advantageously, the axes of rotation spaced on both sides in bearing blocks held under the support plate, which is made in one piece with the bearing blocks as an injection molded part, as well as the support member with its foot and the angled outwardly and obliquely upwards extending support arms is formed with the adjoining bearing shells as a one-piece injection molded part.
Entsprechend einer besonders bevorzugten Ausführungsform der Erfindung sind die Härteversteller gemeinsam auf einem einteiligen Stellring angeordnet, der gegenüber der Auflagerplatte verdrehbar daran angeordnet ist, sodass mit einer einfachen Verdrehung des Stellringes gleichzeitig alle Härteversteller gemeinsam aus einer Federstellung bzw. einer Ruheposition seitlich neben den Fortsätzen in eine Funktionsstellung bzw. Hartverstellung vor den Fortsätzen bewegt werden können, die dort bei Belastung des Auflagerelements gegen Funktionsflächen der Härteversteller anschlagen.According to a particularly preferred embodiment of the invention, the hardness adjusters are arranged together on a one-piece adjusting ring, which is arranged rotatably relative to the support plate, so that at the same time all hardness adjuster together with a simple rotation of the adjusting ring from a spring position or a rest position next to the extensions in one Function position or hard adjustment can be moved in front of the extensions, which strike there against the functional surfaces of the hardness adjuster under load of the support element.
Der Stellring ist hierzu vorteilhafterweise mit Rasten ausgestattet, die im zusammengesetzten Zustand von Stellring und Auflagerplatte Gleitstege der Auflagerplatte umgreifen, sodass der Stellring einfach und sicher drehbar auf bzw. in der Auflagerplatte geführt ist.For this purpose, the adjusting ring is advantageously equipped with detents which engage in the assembled state of adjusting ring and bearing plate sliding webs of the support plate, so that the adjusting ring is easily and safely rotatably guided on or in the support plate.
Bei einer weiteren bevorzugten Ausgestaltung der Erfindung ist der Stellring zusätzlich mit einer die Reibung vergrößernden Oberfläche ausgestattet und von oben so in die Auflagerplatte eingeklippst, dass beide Oberflächen des Stellringes und der Auflagerplatte eine gemeinsame Auflagerfläche bilden, von denen die des Stellringes die der Auflagerplatte auch geringfügig überragen kann, um eine optimierte Fixierung einer darauf aufliegenden Auflage zu gewährleisten.In a further preferred embodiment of the invention, the adjusting ring is additionally equipped with a friction increasing surface and clipped from above into the support plate so that both surfaces of the adjusting ring and the support plate form a common bearing surface, of which the adjusting ring of the support plate also slightly can protrude to ensure an optimized fixation of a resting pad.
Gemäß einer weiteren vorteilhaften Ausbildung des erfinderischen Auflagerelementes ist der Härteversteller mit einer kontinuierlich oder stufig im Radius sich verengenden Funktionsfläche ausgestattet, um die Bewegungsmöglichkeit des Fortsatzes in Abhängigkeit der Winkelposition des Stellringes variierbar zu gestalten, sodass unterschiedlich starke Härteverstellungen verwirklicht werden können.According to a further advantageous embodiment of the inventive support element of the hardness adjuster is equipped with a continuous or stepped in the radius narrowing functional surface to make the possibility of movement of the extension depending on the angular position of the adjusting ring variable, so that different degrees of hardness adjustments can be realized.
Entsprechend einer bevorzugten Variante der Erfindung sind die Lagerschalen zweier benachbarter Tragarme auf koaxialen Drehachsen oder auch einer gemeinsamen Drehachse nebeneinander angeordnet sind, wobei zwei zueinander koaxiale Drehachsen über einen als Trennwandung ausgebildeten Lagerbock voneinander getrennt sein können. Dies verbessert zum einen das Ansprechen der Federfunktion, wobei durch die Trennung sicher eine voneinander unabhängig Funktion gewährleistet wird und zum anderen wird ermöglicht, dass ein Härtversteller in einer ersten Verstellposition nur vor einen Fortsatz der benachbarten Lagerschalen bewegt werden kann und erst in einer zweiten Verstellposition vor beide Fortsätze, sodass durch diese Konstruktion zwei unterschiedliche Härteeinstellungen des Auflagerelements zur Verfügung gestellt werden könnenAccording to a preferred variant of the invention, the bearing shells of two adjacent support arms on coaxial axes of rotation or a common axis of rotation are arranged side by side, wherein two mutually coaxial axes of rotation can be separated from each other via a partition formed as a bearing block. This improves, on the one hand, the response of the spring function, wherein the separation ensures a function independently of each other and, on the other hand, it is possible for a hardness adjuster to be moved in a first adjustment position only in front of an extension of the adjacent bearing shells and only in a second adjustment position Both extensions, so that two different hardness settings of the support element can be provided by this construction
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Tragarme spiegelsymmetrisch zu zwei zueinander rechtwinkligen Flächen durch eine Hochachse des Auflagerelements teilweise in radialer und axialer Richtung, sich nach oben und außen erstreckend, oder teilweise schräg bis tangential dazu am Fußteil angeordnet, wobei diese Anordnung so ausgewählt sein kann, dass eine beliebige Federrate in Längs-, Quer- oder jeder Zwischenrichtung einer Sitz- oder Liegefläche hergestellt werden kann und eine steigend Anzahl von Tragarmen zu einer noch differenzierteren Gestaltungsmöglichkeit führt.In a further advantageous embodiment of the invention, the support arms are mirror-symmetrical to two mutually perpendicular surfaces through a vertical axis of the support element partially in the radial and axial directions, extending upwardly and outwardly, or partially obliquely to tangentially arranged on the foot part, this arrangement being selected It may be that any spring rate in the longitudinal, transverse or any intermediate direction of a sitting or lying surface can be made and an increasing number of support arms leads to a more differentiated design options.
Eine bevorzugte Ausführungsform kann dabei mit Tragarmen mit an ihren oberen Enden mit jeweils einem Hebelarm und einer daran angeordneten Lagerschale ausgeführt sein und/ oder Tragarme aufweisen, die in mindestens zwei dünnere Tragarme aufgespreizt sind, die an ihren oberen Enden ebenfalls jeweils mit einem Hebelarm und einer daran angeordneten Lagerschale ausgestattet sind. Hierdurch wird die Gestaltungsfreiheit der erfindungsgemäßen Auflagerelemente weiter enorm vergrößert.A preferred embodiment may be carried out with support arms having at their upper ends with a respective lever arm and a bearing shell disposed thereon and / or support arms which are spread in at least two thinner support arms, which at their upper ends also each with a lever arm and a equipped thereon bearing shell are equipped. As a result, the freedom of design of the support elements according to the invention is further increased enormously.
