Description

Die Erfindung betrifft ein härteverstellbares Einzelfederelement eines Sitz- oder Liegemöbels, aus einem Unterteil mit Bolzenaufnahmen, einem Oberteil mit einer Auflagerfläche sowie aus einem dazwischen angeordneten Federelement aus elastischen Elementen, wobei mindestens zwei zueinander gerichtete Funktionsflächen zweier sich beabstandet gegenüber liegenden und sich von unten außen mittig nach oben erstreckenden Bogenelementen des Federelementes bei einer senkrechten Krafteinwirkung entlang eines horizontalen Reaktionsweges sich aufeinander zu bewegen könnend ausgebildet sind und dazwischen ein aktivierbarer Verriegelungskörper eingreift, der in einer aktivierten Verriegelungsstellung den horizontalen Reaktionsweg teilweise oder vollständig blockiert.The invention relates to a hardness-adjustable single spring element of a sitting or lying furniture, a lower part with bolt receptacles, an upper part with a bearing surface and an interposed spring element made of elastic elements, wherein at least two mutually facing functional surfaces of two spaced opposite and centered from below outside upwardly extending arcuate elements of the spring element in a vertical force along a horizontal path of reaction are able to move towards each other formed and intervenes an activatable locking body which blocks the horizontal reaction path partially or completely in an activated locking position.

Aus der EP 1714588 A1 ist eine Unterfederung mit integrierter Härteverstellung bekannt, die eine solche Härteverstellung für eine Unterfederung aufweist, die als Einzelfederelement ausgeführt sein kann, jedoch vorzugsweise als elastisches Endpunktlager für Federlatten von Bettlattenrosten ausgebildet ist.From the EP 1714588 A1 is known a lower spring with integrated hardness adjustment, which has such a hardness adjustment for a spring base, which may be designed as a single spring element, but is preferably designed as an elastic Endpunktlager for spring slats of bed slatted frames.

In einer Ausführungsform als Einzelfederelement weist diese bekannte Unterfederung den Nachteil auf, dass das gesamte Bauteil bis auf den Verriegelungskörper einteilig und aus einem relativ elastischen Material ausgebildet ist und das Unterteil mit seinem fixen Abstand der Bolzenaufnahmen zur Lagerung an einem starren Bettunterteil nur wenig Variationsmöglichkeiten hinsichtlich seiner Anordnung bietet.In one embodiment, as a single spring element, this known spring base has the disadvantage that the entire component is formed integrally up to the locking body and a relatively elastic material and the lower part with its fixed distance of the bolt receptacles for storage on a rigid bed base only little variation in terms of his Arrangement offers.

Aufgabe der Erfindung ist es, ein härteverstellbares Einzelfederelement zur Verfügung zu stellen, welches für seinen Einsatzzweck optimiert ist und eine erhöhte Variabilität in seiner Ausführung und seinen Anordnungsmöglichkeiten besitzt.The object of the invention is to provide a hardness-adjustable single spring element available, which is optimized for its application and has increased variability in its design and arrangement options.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß im Zusammenhang mit den Oberbegriffsmerkmalen dadurch, dass die Auflagerfläche als Auflagerteller ausgebildet ist, der Verriegelungskörper einen Stellknopf aufweist, der in dem Auflagerteller verdrehbar gelagert ist und dass die Bolzenaufnahmen in einem Fußteil gelagert sind, welches Befestigungsvorrichtungen zur beliebigen Anordnung auf einem starren Bettunterteil, wie etwa einem Querholm, aufweist.The solution of this object is achieved according to the invention in connection with the preamble features in that the support surface is formed as a support plate, the locking body has a knob which is rotatably mounted in the support plate and that the bolt receptacles are mounted in a foot, which mounting devices for arbitrary arrangement a rigid bed base, such as a cross bar, has.

Die Ausgestaltung der Auflagerfläche als Auflagerteller hat zum einen den Vorteil, dass er aus einem erheblich starreren Material gefertigt werden kann als das Federelement, so dass er für die von ihm zu erfüllenden Anforderungen und auch hinsichtlich der Materialkosten optimiert ausgebildet sein kann.The design of the support surface as a support plate on the one hand has the advantage that it can be made of a material significantly more rigid than the spring element, so that it can be optimized for the requirements to be met by him and also in terms of material costs.

Ein weiterer Vorteil eines solchen separaten Auflagertellers besteht in der Möglichkeit seine Größe so zu variieren, dass beispielsweise in einem Liegeflächenbereich mit einer stetigen höheren Gewichtsbelastung, beispielsweise im Auflagebereich des Unterkörpers, die Einzelfederelemente näher zusammengerückt an einem Bettunterteil angeordnet werden können, wobei hier kleinere Auflagerteller verwandt werden als in einem Bereich des Liegemöbels, welches regelmäßig mit nur geringen Gewichtskräften eines Benutzers beaufschlagt wird. Die Anordnung des Stellknopfes des Verriegelungskörpers in dem Auflagerteller ermöglicht einen passgenauen Sitz des Stellknopfes sowie seine einfache Betätigung, da die Haft- und Gleitreibungskräfte gegenüber seiner Anordnung in einem elastischen Grundwerkstoff deutlich reduziert sind. Besonders vorteilhaft ist jedoch die Anordnung der Bolzenaufnahmen in einem Fußteil, so dass das Einzelfederelement an jedem beliebigen Ort eines starren Bettunterteils, wie etwa auf einem starren Querholm, festgelegt werden kann und die Verteilung der einzelnen Einzelfederelemente leicht und einfach variiert werden kann. Das Einzelfederelement wird so vollkommen unabhängig von dem fixen Abstand der Bolzenaufnahmen seines Unterteils.Another advantage of such a separate support plate is the ability to vary its size so that, for example, in a lying area with a steady higher weight load, for example, in the support area of the lower body, the single spring elements can be arranged closer together at a bed base, here smaller Auflagerteller related are considered to be in an area of the reclining furniture which is regularly subjected to only a slight weight load by a user. The arrangement of the adjusting knob of the locking body in the support plate allows a snug fit of the knob and its simple operation, since the adhesive and Gleitreibungskräfte are significantly reduced compared to its arrangement in an elastic base material. Particularly advantageous, however, is the arrangement of the bolt receptacles in a foot part, so that the single spring element can be fixed at any location of a rigid bed base, such as on a rigid cross member, and the distribution of the individual individual spring elements can be varied easily and simply. The single spring element is so completely independent of the fixed distance of the bolt receptacles of its lower part.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject of the invention will become apparent with and in combination from the following subclaims.

Gemäß einer besonders bevorzugten Ausführungsform des Gegenstandes der Erfindung sind nicht nur der Auflagerteller, sondern auch der Verriegelungskörper, das Federelement und das Fußteil aus für ihren jeweiligen Verwendungszweck optimierten Kunststoffen gefertigt, wodurch insgesamt ein wirtschaftliches und dauerhaft funktionstüchtiges härteverstellbares Einzelfederelement zur Verfügung gestellt wird.According to a particularly preferred embodiment of the object of the invention, not only the support plate, but also the locking body, the spring element and the foot are made of optimized for their respective purpose plastics, making a total of an economical and permanently functional hardness adjustable single spring element is provided.

Entsprechend einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die einzelnen Bauteile über Rastverbindungen miteinander verbunden, so dass die einzelnen Bauteile nicht nur aufgrund der Aufgabenteilung vereinfacht ausgebildet sein können, sondern auch werkzeugfrei miteinander verbunden und im Fall einer Entsorgung eines Sitz- oder Liegemöbels auch einfach wieder sortenrein zerlegt werden können.According to a further advantageous embodiment of the invention, the individual components are interconnected via snap-in connections, so that the individual components can be simplified not only due to the division of tasks, but also tool-free interconnected and in the case of disposal of a sitting or lying furniture also easily sorted again can be disassembled.

Das Fußteil weist bevorzugterweise kreiszylindrische Achsen zur Aufnahme der Bolzenaufnahmen auf, die darauf aufgeklippst sind, so dass eine Drehung der Bolzenaufnahmen um die Querbolzen möglich ist. Bei Bedarf kann auch eine verdrehfreie Montage vorgesehen werden.The foot part preferably has circular-cylindrical axes for receiving the bolt receptacles, which are clipped onto it, so that rotation of the bolt receptacles about the transverse bolts is possible. If required, a torsion-free assembly can be provided.

Bei einer weiteren vorteilhaften Ausführungsform der Erfindung sind die Auflagerteller in unterschiedlichen Größen und/ oder Formen ausgebildet, um etwa durch die Auswahl kleinerer Auflagerteller die Dichte der nebeneinander anzuordnenden Einzelfederelemente erhöhen zu können oder aber durch Verwendung asymmetrischer Auflagerteller eine ausreichend große Holmüberdeckung im Bereich der Seitenholme eines Liegemöbels verwirklichen zu können.In a further advantageous embodiment of the invention, the support plates are formed in different sizes and / or shapes in order to increase the density of juxtaposed individual spring elements approximately by the selection of smaller support plate or by using asymmetric support plate a sufficiently large spar cover in the side of a side rails To be able to realize sunbeds.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das Fußteil mit mehr als zwei Lagerungen für mehr als zwei Bolzenaufnahmen eines Unterteils eines Einzelfederelementes ausgestattet, welches dann entsprechend mehr als zwei Bogenelemente mit jeweils einer Funktionsfläche aufweist und dessen Verriegelungskörper im horizontalen Querschnitt sternförmig mit drei oder mehr Strahlen ausgebildet ist, deren äußeren Stirnseiten bei aktivierter Verriegelungsstellung die Kontaktflächen mit den Funktionsflächen des Verriegelungskörpers bilden und die freie Strecke zwischen den Funktionsflächen und den Eckinnenflächen des Verriegelungskörpers bei deaktivierter Verriegelung den horizontalen Reaktionsweg begrenzen. Eine solche vorteilhafte Variante weist bevorzugt vier Drehachsen für Bolzenaufnahmen auf, von denen zwei jeweils gegenüberliegend und diese rechtwinklig zu den anderen beiden Achsen im Fußteil angeordnet sein könnten, wobei auch das Federelement vier Bogenelemente aufweist, die sich von unten außen mittig nach innen bis zu dem im Horizontalschnitt kreuzförmigen Verriegelungskörper erstrecken. Hierdurch wird ein Einzelfederelement zur Verfügung gestellt, welches in Längs- und Querrichtung die gleichen Federraten aufweist.According to a further advantageous embodiment of the invention, the foot part is equipped with more than two supports for more than two bolt receptacles of a lower part of a single spring element, which then correspondingly more than two arch elements each having a functional surface and the locking body in the horizontal cross-section star-shaped with three or more beams is formed, the outer end faces form the contact surfaces with the functional surfaces of the locking body in the activated locking position and the free route between the functional surfaces and the inner corner surfaces of the locking body with disabled locking limit the horizontal pathway. Such an advantageous variant preferably has four axes of rotation for bolt receptacles, of which two in each case opposite and this could be arranged at right angles to the other two axes in the foot part, wherein the spring element has four arch elements, which from the center of the outside center to the inside extend in horizontal section cross-shaped locking body. As a result, a single spring element is provided which has the same spring rates in the longitudinal and transverse directions.

Bei einer weiteren vorteilhaften Ausführungsform der Erfindung sind die Fußteile des Einzelfederelementes verschieblich auf einem Querholm gelagert, so dass der Abstand der Einzelfederelemente auch nach Fertigstellung einer Auflagerfläche für eine Matratze noch beliebig variiert werden kann.In a further advantageous embodiment of the invention, the foot parts of the single spring element are slidably mounted on a cross member, so that the distance of the individual spring elements can be varied as desired even after completion of a support surface for a mattress.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand von Zeichnungen näher beschrieben. Es zeigen:

Fig. 1
ein härteverstellbares Einzelfederelement mit außer Funktion gesetztem Verriegelungskörper und
Fig. 2
das Einzelfederelement der Fig. 1 mit in Betrieb gesetztem Verriegelungskörper.
An exemplary embodiment of the invention is described in more detail below with reference to drawings. Show it:
Fig. 1
a hardness adjustable single spring element with out of action set locking body and
Fig. 2
the single spring element of Fig. 1 with put into operation locking body.

Das härteverstellbare Einzelfederelement 1 besteht aus einem Auflagerteller 3 auf einem Federelement 4, welches im unteren Bereich Bolzenaufnahmen 14 aufweist, mit denen es in einem Fußteil 2 gelagert ist, welches auf einem starren Querholm 10 eines Bettunterteils festgelegt ist.The hardness-adjustable single spring element 1 consists of a support plate 3 on a spring element 4, which has at the bottom of bolt receptacles 14, with which it is mounted in a foot part 2, which is fixed on a rigid cross member 10 of a bed base.

Von den Bolzenaufnahmen 14 erstrecken sich von unten außen mittig nach oben gerichtete elastische Bogenelemente 9 als wesentliche Bauteile des Federelementes 4 in Richtung einer senkrechten Mittelachse des Einzelfederelementes 1 und weisen in ihren oberen Bereichen vertikale Funktionsflächen 7 auf, die sich im unbelasteten Zustand des Einzelfederelementes beabstandet und beabstandet von dem dazwischen angeordneten Verriegelungskörper 6 einander gegenüberliegen und über eine Verbindungslasche 11 elastisch miteinander verbunden sind. Der freie Raum zwischen den Funktionsflächen 7 und dem Verriegelungskörper 6 entspricht dem möglichen Reaktionsweg 5, über den die elastischen Bogenelemente 9 bei einer senkrechten Kraftbeanspruchung des Einzelfederelementes 1 nach innen ausweichen können, sofern sich der Verriegelungskörper 6 in einer deaktivierten Verriegelungsstellung befindet, wie dies in Fig. 1 dargestellt ist. Der Verriegelungskörper 6 ist als eine Art Drehschieber ausgebildet, über einen Stellknopf 13 drehbar in dem Auflagerteller 3 gelagert und kann um 90° aus einer ausgeschalteten in eine vollständig eingeschaltete Stellung gedreht werden.Of the bolt receivers 14 extending from the outside downwardly upwardly directed elastic arch members 9 as essential components of the spring element 4 in the direction of a vertical center axis of the single spring element 1 and have in their upper regions vertical functional surfaces 7, which are spaced in the unloaded state of the single spring element and spaced from the one in between arranged locking body 6 facing each other and are connected to each other via a connecting plate 11 elastically. The free space between the functional surfaces 7 and the locking body 6 corresponds to the possible reaction path 5, over which the elastic sheet elements 9 can dodge at a vertical force stress of the single spring element 1 inside, if the locking body 6 is in a deactivated locking position, as in Fig. 1 is shown. The locking body 6 is formed as a kind of rotary valve, rotatably supported by a knob 13 in the support plate 3 and can be rotated by 90 ° from a switched-off to a fully on position.

Wie in Fig. 2 dargestellt, ist der Verriegelungskörper 6 in eine aktive Verriegelungsstellung verdreht, in der er den freien Reaktionsweg 5 blockiert, da die Stirnseiten des Verriegelungskörpers 6 auch ohne Belastung des Einzelfederelementes 1 bereits an den Funktionsflächen 7 der Bogenelemente 9 anliegen.As in Fig. 2 shown, the locking body 6 is rotated to an active locking position in which he blocks the free reaction path 5, since the end faces of the locking body 6 even without loading of the single spring element 1 abut the functional surfaces 7 of the sheet elements 9.

Die Fußteile 2 des Einzelfederelementes 1 sind an beliebiger Stelle eines starren Querholmes 10 oder aber auch auf einer zeichnerisch nicht dargestellten ebenen Fläche wahlfrei zu montieren, so dass bei einer zusätzlichen Variation der Größe der Auflagerteller 3 jede beliebige Komposition einer Auflagerfläche für eine Matratze eines Sitz- oder Liegemöbels herstellbar ist.The foot parts 2 of the single spring element 1 are to be mounted optionally at any point of a rigid cross member 10 or even on a flat surface, not shown, so that with an additional variation of the size of the support plate 3 any composition of a support surface for a mattress of a seat or reclining furniture can be produced.
