Description

Die Erfindung betrifft einen Federkörper einer Einzelsegmentunterfederung eines Sitz- oder Liegemöbels oder einer Matratze, mit jeweils aus einem Auflagerteller, mindestens einem Federkörper und einer Grundplatte bestehenden Einzelfederelementen.The invention relates to a spring body of a Einzelsegmentunterfederung a Sitting or lying furniture or a mattress, each with a support plate, at least a spring body and a base plate existing single spring elements.

Es ist ein Polsterelement eines Bettsystems bekannt, DE 297 21 656 U 1, welches aus einem einteilig ausgebildeten Spritzgussteil besteht und eine komplizierte dreidimensionale Gestaltung aufweist, die für ihre Herstellung aufwendige und teure Spritzgussformen erfordert. Die von einer unteren Basisplatte sich nach außen und oben erstreckenden Blattfedern sind an ihren Enden jeweils mit Auflagerflächen versehen, sodass bei dieser bekannten einstückigen Ausführungsform eines Polsterelementes nur ein Kompromiss zwischen den gewünschten Federraten und der erforderlichen Festigkeit einer Auflagefläche erzielt werden kann.It is a padding element of a bed system known, DE 297 21 656 U 1, which consists of a one-piece molded part and a complicated three-dimensional Has design that costly and expensive injection molds for their preparation requires. The from a lower base plate extending outwards and upwards Leaf springs are provided at their ends with bearing surfaces, so at this known one-piece embodiment of a cushion element only a compromise between the desired spring rates and the required strength of a support surface can be achieved.

Weiterhin ist ein Rahmen für Liege- oder Sitzmöbel bekannt, DE 196 37 933 C, welcher Federelemente aufweist, die aus einer unteren, C-förmigen, liegend angeordneten Blattfeder und einer zu dieser spiegelsymmetrisch angeordneten oberen Blattfeder besteht, deren Enden jeweils miteinander verbunden sind. Nachteilig an diesem bekannten Federelement ist die Tatsache, dass es sich nur in eine Richtung bzw. in einer senkrechten Ebene durch die Blattfedern verformen kann, die keine seitliche Verformung des Federelementes zulassen.Furthermore, a frame for reclining or seating furniture is known, DE 196 37 933 C, which has spring elements which are arranged lying in a lower, C-shaped, lying Leaf spring and a mirror-symmetrically arranged to this upper leaf spring consists, whose ends are connected to each other. A disadvantage of this known Spring element is the fact that it is only in one direction or in one vertical plane through the leaf springs can deform, no lateral deformation allow the spring element.

Ebenfalls bekannt ist eine elastische Rahmenkonstruktion einer Matratze, eines Stuhls oder einer Unterpolsterung, US-A-5 632 473, welche elastische Elemente aufweist, die eine komplexe räumliche Struktur aufweisen, sodass deren Fertigung aufwendig und damit sehr unwirtschaftlich ist.Also known is an elastic frame construction of a mattress, a Chair or padding, US-A-5 632 473, which has elastic elements, which have a complex spatial structure, so that their production consuming and thus very uneconomical.

Weiterhin sind Latex- bzw. Schaumstoffmatratzen bekannt, die Ausnehmungen für Federelemente aufweisen, die ihrerseits aus in Taschen eingenahten Tonnenfedem, FR-A-2 737 096, oder aber aus großen Kunststoffkugeln, DE 87 14 843 U, bestehen, die jeweils nur geringe Auflagerflächen aufweisen und sich deswegen nicht zur Erzeugung von homogenen ebenen Liegeflächen eignen.Furthermore, latex or foam mattresses are known, the recesses for spring elements, which in turn consist of pocket springs sewn in pockets, FR-A-2 737 096, or from large plastic balls, DE 87 14 843 U, consist, each have only small bearing surfaces and therefore not for production of homogeneous flat lying surfaces are suitable.

Aufgabe der Erfindung ist es, eine Einzelsegmentunterfederung zur Verfügung zu stellen, die einfach herzustellen ist und deren Federungseigenschaften wahlfrei abgestimmt werden können. The object of the invention is to provide a Einzelsegmentunterfederung available which is easy to manufacture and whose suspension properties are matched optional can be.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß in Zusammenhang mit den Oberbegriffsmerkmalen aus den kennzeichnenden Merkmalen des Hauptanspruches.The solution of this object is achieved according to the invention in connection with Outline features of the characterizing features of the main claim.

Die Einzelsegmentunterfederung besteht im einfachsten Fall aus einem separaten Federkörper, einem Auflageteller und einer Grundplatte, wobei der Federkörper aus in einer geraden oder auch gewölbten Ebene um ein auf einer vertikalen Mittelachse liegenden ersten Zentrum und um die Mittelachse herum angeordneten Federungsarmen besteht, die zur Mittelachse und einem vom ersten Zentrum beabstandeten auf der vertikalen Mittelachse liegenden zweiten Zentrum korbartig hin elastisch umgebogen sind und dort mit den an ihren äußeren Enden vorgesehen Rastmitteln in Rasten einer Rastenaufnahme eingreifen und so einen dreidimensionalen Federkörper bilden. Die Herstellung des Federkörpers kann dadurch erheblich kostengünstiger erfolgen, da die Spritzgießform infolge des im Ausgangszustand im wesentlichen zweidimensionalen Federkörpers mit geringer Dicke erheblich einfacher zu fertigen und auch keine mehrteilige Form der Presse erforderlich ist. Dies gilt ebenso für einen Federkörper mit einer vertikalen Trennungsebene, dessen Ausgangsprodukt bereits schalenförmig sich in Richtung auf das zweite Zentrum erstreckende und damit einstückig ausgebildete Federungsarme aufweist. Weiterhin kann die Federrate vollkommen unabhängig von den Festigkeitsanforderungen an einen Auflagerteller oder eine Grundplatte zur Befestigung eines Einzelfederelementes auf einem Querholm oder einer ebenen Fläche eines Sitzoder Liegemöbels vorherbestimmt werden, da der Federkörper ein separates Bauteil, vorzugsweise aus einem Elastomer, darstellt, dessen Federungsarme unterschiedliche Formen aufweisen können, die sich auf die Federungs- und Dämpfungseigenschaften des Federkörpers auswirken. In einem Sitz- oder Liegemöbel, insbesondere in einem Bett als Unterfederung einer Matratze oder auch als Teil einer Matratze, lassen sich mit dem mit den Federkörpern konstruierten Federelementen Zonen verschiedener Härten und Federwege erzeugen, wodurch sich das Liegeverhalten progressiv verbessern lässt.The single-segment suspension consists in the simplest case of a separate Spring body, a support plate and a base plate, wherein the spring body made in a straight or curved plane around one on a vertical central axis lying first center and around the central axis arranged suspension arms exists to the central axis and a spaced from the first center on the vertical center axis lying second center basket-like elastically bent over are and there with the provided at their outer ends latching means in detents one Engage catch recording and so form a three-dimensional spring body. The Production of the spring body can be done considerably cheaper because the Injection mold as a result of the spring in the initial state substantially two-dimensional spring body With a small thickness much easier to manufacture and no multi-part Form of the press is required. This also applies to a spring body with a vertical Separation plane whose starting product is already shell-shaped in the direction on the second center extending and thus integrally formed suspension arms having. Furthermore, the spring rate can be completely independent of the Strength requirements for a support plate or a base plate for attachment a single spring element on a transverse spar or a flat surface of a seat or Beds are predestined, since the spring body is a separate component, preferably of an elastomer, represents, whose suspension arms different Shapes may have on the suspension and damping properties of the spring body. In a sitting or lying furniture, especially in one Bed as a spring under a mattress or as part of a mattress, can be with the spring elements constructed with the spring bodies zones of different hardnesses and spring travel, which can improve the lying behavior progressively.

Weitere vorteilhafte Ausführungsformen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den weiteren Unteransprüchen.Further advantageous embodiments of the subject matter of the invention result with and in combination of the other subclaims.

Der Federkörper besteht bevorzugt aus drei oder mehr Federungsarmen, wobei deren Anzahl und Geometrie frei wählbar ist. Von besonderem Vorteil ist dabei, dass eine gewünschte Federungshärte, Federhöhe oder auch eine Federrate über die Anzahl, Länge, die Form, die Dicke und die Breite der Federungsarme oder auch über die Shore-Härte des Grundmaterials vorherbestimmbar sind. Dadurch lassen sich auf einfache Art und Weise Einzelfederelemente unterschiedlicher Federrate für die verschiedenen Belastungen in einem Sitz- oder Liegemöbel oder einer Matratze herstellen.The spring body preferably consists of three or more suspension arms, wherein their number and geometry is freely selectable. Of particular advantage is that a desired suspension hardness, spring height or also a spring rate over the number, Length, shape, thickness and width of the suspension arms or over the Shore hardness of the base material are predictable. This allows for easy Fashion single spring elements of different spring rate for the different ones Make burdens in a sitting or lying furniture or a mattress.

Weiterhin ist eine bevorzugte Ausführungsform des Gegenstandes der Erfindung innerhalb des Federkörpers mit einem zweiten Federkörper mit kürzeren Federungsarmen ausgestattet oder es ist in dem von den verrasteten Federungsarmen erzeugten korbartigen Gebilde ein zusätzliches Feder- oder Dämpfungselement eingesetzt, sodass beispielsweise nach einem freien Federweg des äußeren Federkörpers mit einer weichen Federrate eine sich verhärtende Unterfederung geschaffen werden kann.Furthermore, a preferred embodiment of the subject of the invention within the spring body with a second spring body with shorter suspension arms equipped or it is in the one produced by the latched suspension arms basket-like structures used an additional spring or damping element, so that for example, after a free spring travel of the outer spring body with a soft Spring rate a hardening spring suspension can be created.

Von dem ersten Zentrum des Federkörpers können Vorteilhafterweise weitere sich radial erstreckende Verbindungsarme ausgehen, deren Enden im Einbauzustand der Einzelfederelemente mit benachbarten Einzelfederelementen verbunden sind, sodass benachbarte Einzelfederelemente bei Belastung eines mittigen Einzelfederelementes mit zur Abfederung dieser Belastung herangezogen werden können. Eine solche Verbindung kann jedoch auch über separate, die Auflagerteller benachbarter Einzelfederelemente miteinander verbindende Stege erfolgen, sodass je nach Einsatzgebiet des Federkörpers eine Vernetzung von Einzelfederelementen erfolgen oder unterbleiben kann. From the first center of the spring body can advantageously further extend radially extending connecting arms, the ends in the installed state the individual spring elements are connected to adjacent individual spring elements, so that adjacent single spring elements under load of a central single spring element can be used to mitigate this burden. Such However, connection can also be via separate, the support plate adjacent single spring elements connecting webs are made, so depending on the application of the Fed body a networking of single spring elements done or omitted can.

Bei einer bevorzugten Ausführungsform der Erfindung ist die Rastenaufnahme für die Rasten der Federungsarme mit einer Grundplatte zur Befestigung des Einzelfederelements auf einer Federlatte oder einer ebenen Fläche einstückig ausgebildet, sodass die Anzahl der Einzelteile des einfachsten zu erzeugenden Einzelfederelementes auf drei beschränkt ist. Eine weiter gehende Minimierung der Bauteilanzahl kann erreicht werden, wenn der obere Auflagerteller ebenfalls stoffschlüssig mit dem oberen Zentrum des Federkörpers ausgebildet ist.In a preferred embodiment of the invention is the catch recording for the detents of the suspension arms with a base plate for fastening the single spring element formed integrally on a spring bar or a flat surface so that the number of items of the simplest single spring element to be produced is limited to three. A further minimization of the number of components can be achieved be, if the upper support plate also cohesively with the upper Center of the spring body is formed.

Gemäß einer weiteren Ausführungsform der Erfindung können zur Erzeugung eines besonders hohen Einzelfederelements auch mehrere Federkörper übereinander angeordnet werden, wobei dann vorzugsweise im oberen Zentrum eines Federkörpers Rastenaufnahmen für die Rasten der Federungsarme eines darüber anzuordnenden Federkörpers vorgesehen sein können. Solche Rastenaufnahmen können auch einem Auflagerteller als Befestigung dienen.According to a further embodiment of the invention, for generating a particularly high single spring element and several spring body above the other are arranged, in which case preferably in the upper center of a spring body Notch recordings for the detents of the suspension arms of a spring body to be arranged above can be provided. Such detent recesses can also be a support plate serve as attachment.

Vorteilhaft ist ebenfalls eine Version des Gegenstandes der Erfindung, dessen Federungsarme seitliche Laschen aufweisen, die mit Laschen benachbarter Federungsarme verrastbar sind, wodurch eine zusätzliche Stabilität gegen seitliches Ausweichen eines Einzelfederelements bei schräger Belastung erreicht wird.Also advantageous is a version of the article of the invention whose Suspension arms have lateral tabs, with tabs of adjacent suspension arms latched, creating additional stability against lateral evasion a single spring element is achieved at oblique load.

Als weitere wesentliche Neuerung kann eine Ausbildung der Erfindung hervorgehoben werden, bei der der Federkörper vollständig oder teilweise oder auch eine gesamtes Einzelfederelement mit Latex umschäumt ist. Mit einem solchen Bauteil lässt sich zum Beispiel eine Latexmatratze ausrüsten, wobei die umschäumten Federkörper oder Einzelfedersegmente in Ausnehmung in der Latexmatratze eingesetzt sind, die dadurch erheblich leichter und wesentlich luftdurchlässiger wird. Eine Latexmatratze mit darin eingesetzten Federkörpern oder Einzelfederelementen aus umschäumten oder bloßem Kunststoff wird dadurch im Gegensatz zu schweren Voll-Latexmatratzen sehr viel leichter handhabbar und weist zudem einen hervorragenden Wert für den Feuchtigkeitstransport auf, sodass auch stark transpirierende Menschen eine solchen Matratze benutzen können.As a further significant innovation, an embodiment of the invention can be highlighted be in which the spring body completely or partially or even an entire Single spring element is foamed with latex. With such a component can be For example, equip a latex mattress, wherein the foam-coated spring body or Single spring segments are inserted into recess in the latex mattress, thereby considerably lighter and significantly more permeable to air. A latex mattress with in it used spring bodies or single spring elements of foam or bare This makes plastic much lighter than heavy full-latex mattresses manageable and also has an excellent value for moisture transport on, so that even highly transpiring people use such a mattress can.
