Die Erfindung betrifft eine Unterfederung nach dem Oberbegriff der Ansprüche 1 und 20. Außerdem betrifft die Erfindung ein Schlaf-, Sitz- oder Liegemöbel mit einer derartigen Unterfederung.The invention relates to a spring base according to the preamble of
Die genannten Möbel weisen in der Regel eine Federung aus einem sogenannten Lattenrost auf. Auf dem Lattenrost liegt eine Auflage oder Polsterung mit einer Sitz- oder Liegefläche. Die Federung wird deshalb als Unterfederung bezeichnet. Der Lattenrost verfügt über eine Mehrzahl von mit Abstand parallel nebeneinander angeordneten Trägerprofilen, in hölzener Ausführung auch als Federleisten bezeichnet. Die Trägerprofile sind üblicherweise durch Stützkörper mit Längsholmen eines rechteckigen Rahmens verbunden, welcher Teil der Unterfederung ist. Die Trägerprofile erstrecken sich quer zu den Längsholmen, können unterschiedliche Querschnitte aufweisen und aus den unterschiedlichsten Werkstoffen hergestellt sein. Bei Druck auf die Polsterung geben die Trägerprofile elastisch nach bzw. biegen sich federnd.The furniture mentioned usually have a suspension of a so-called slatted frame. On the slatted base is a support or upholstery with a sitting or lying area. The suspension is therefore referred to as a suspension. The slatted base has a plurality of spaced apart parallel juxtaposed carrier profiles, in holztener execution also referred to as slats. The support profiles are usually connected by support body with longitudinal members of a rectangular frame, which is part of the spring base. The carrier profiles extend transversely to the longitudinal beams, may have different cross-sections and be made of a variety of materials. When pressure is applied to the upholstery, the carrier profiles yield elastically or bend resiliently.
Eine Federung ist aus dem Dokument
Aufgabe der vorliegenden Erfindung ist die Schaffung einer individuell anpassbaren Unterfederung. Insbesondere sollen die Trägerprofile einzeln oder gruppenweise individuell einstellbar sein.Object of the present invention is to provide a customizable spring base. In particular, the carrier profiles should be individually or group individually adjustable.
Die erfindungsgemäße Unterfederung weist alle Merkmale des Anspruchs 1 auf. Somit sind die Trägerprofile mit mindestens einer von der Längsachse beabstandeten Verstärkung versehen und um die Längsachse oder um eine hierzu parallele Achse drehbar zur Veränderung ihrer Biegesteifigkeit gegen eine Kraft in Richtung senkrecht zur vorzugsweise gemeinsamen Ebene, die in Richtung quer zur Längsachse geradlinig, aber auch ungeradlinig, insbesondere abgewinkelt oder gewölbt verlaufen kann. Die Trägerprofile liegen unmittelbar oder mittelbar an der Polsterung an und können durch eine einfache Drehbewegung um ihre Längsachsen oder um hierzu parallele Achsen auf eine bestimmte Last eingestellt werden. Insbesondere ist eine kontinuierliche Verstellung möglich. Die Trägerprofile sind dann entsprechend kontinuierlich drehbar gelagert. Vorteilhaft ist aber auch eine Verstellung in kleinen Schritten bzw. Drehwinkeln. Bevorzugt ist eine Verstellmöglichkeit derart, dass der Drehwinkel zwischen der härtesten Position einerseits und der weichsten Position andererseits 90° oder 180° beträgt. Die Trägerprofile können auf verschiedenste Art und Weise ausgebildet sein, mit verschiedenen Querschnitten, etwa rechteckig, quadratisch, sechseckig, viereckig, oval, kreisrund, hohl oder massiv. Auch können die Trägerprofile über ihre Länge Änderungen in Form und Größe des Querschnitts aufweisen.The lower suspension according to the invention has all the features of
Erfindungsgemäß können die Trägerprofile zwei von der Längsachse beabstandete und einander gegenüberliegende Verstärkungen aufweisen. Die Verstärkungen weisen so zueinander einen Abstand von 180° auf. Zwischen einer relativ harten und einer relativ weichen Position liegen dann etwa 90°.According to the invention, the carrier profiles may have two reinforcements which are spaced apart from the longitudinal axis and located opposite one another. The reinforcements have a distance of 180 ° to each other. Between a relatively hard and a relatively soft position are then about 90 °.
Nach einem weiteren Gedanken der Erfindung sind die Verstärkungen insbesondere zugsteife Einlagen in Wandungen oder Auflagen auf Wandungen der Trägerprofile. Die zugsteifen Einlagen können durch Auswahl spezieller Werkstoffe oder durch erhöhte Dichte ohnehin vorhandener zugsteifer Werkstoffe gebildet sein. Außerhalb der Verstärkungen weisen die Trägerprofile eine demgegenüber geringere Zugsteifigkeit auf.According to a further aspect of the invention, the reinforcements are in particular tension-resistant inserts in walls or supports on walls of the carrier profiles. The tension-resistant inserts can be formed by selecting special materials or by increasing the density of already existing tensile rigid materials. Outside the reinforcements, the carrier profiles have a lower tensile rigidity on the other hand.
Vorteilhafterweise sind die Trägerprofile rohrförmig ausgebildet mit einer umlaufenden Innenfläche und einer umlaufenden Außenfläche, wobei die Verstärkungen insbesondere innen auf der Innenfläche, außen auf der Außenfläche und/oder zwischen Innenfläche und Außenfläche vorgesehen sind. Vorzugsweise sind Verstärkungen zwischen Innen- und Außenfläche eingearbeitet. Beispielsweise sind die Trägerprofile aus Kunststoff, nämlich als glasfaserverstärkte (GFK-)Rohre ausgebildet und weisen in ausgewählten Querschnittsbereichen Verstärkungen aus Kohlefaser auf. Kohlefaser hat eine höhere Zugsteifigkeit als die für GFK-Teile herkömmlicherweise verwendeten Glasfasern, nämlich bei gleicher Last eine geringere Dehnung.Advantageously, the carrier profiles are tubular with a circumferential inner surface and a circumferential outer surface, wherein the reinforcements are provided in particular on the inner surface, on the outer surface and / or between inner surface and outer surface. Preferably, reinforcements between the inner and outer surface are incorporated. For example, the support profiles are made of plastic, namely as glass fiber reinforced (GRP) pipes and have reinforcements made of carbon fiber in selected cross-sectional areas. Carbon fiber has a higher tensile stiffness than the glass fibers conventionally used for GRP parts, namely a lower elongation for the same load.
Nach einem weiteren Gedanken der Erfindung weisen die Trägerprofile zwei durch die Geometrie und/oder das Material gegebene Achsen unterschiedlicher Biegesteifigkeit auf, wobei die beiden Achsen zueinander und insbesondere auch zur Längsachse etwa senkrecht verlaufen. In diesem Fall liegt zwischen der härtesten Position und der weichsten Position des Federkörpers ein Drehwinkel von 90°. Eine individuelle Einstellung des Federkörpers ist schnell durchführbar.According to a further aspect of the invention, the carrier profiles have two axes of different flexural stiffness given by the geometry and / or the material, wherein the two axes extend approximately perpendicular to one another and in particular also to the longitudinal axis. In this case, between the hardest position and the softest position of the spring body is a rotation angle of 90 °. An individual adjustment of the spring body can be carried out quickly.
Nach einem weiteren Gedanken der Erfindung weisen die Trägerprofile im Querschnitt zueinander senkrecht stehende Achsen unterschiedlicher Biegesteifigkeit auf. Zusätzlich weisen die Trägerprofile in Richtung einer diesen Achsen größere Abmessungen auf als in Richtung der anderen Achse. Bei dieser speziellen Ausführung sind die Trägerprofile im Querschnitt nicht rotationssymmetrisch aber beispielsweise rechteckig oder oval.According to a further aspect of the invention, the carrier profiles in cross section to each other perpendicular axes of different flexural rigidity. In addition, the carrier profiles in the direction of these axes have larger dimensions than in the direction of the other axis. In this particular embodiment, the carrier profiles are not rotationally symmetrical in cross-section but, for example, rectangular or oval.
Vorteilhafterweise sind die Trägerprofile in Seitenlagem, Drehlagern oder Kipplagern gehalten. Seitenlager halten die Trägerprofile insbesondere an deren Enden. Bei Ausbildung als Drehlager können die Trägerprofile in den Lagern verdreht werden. Auch die Drehlager halten die Trägerprofile vorzugsweise an deren Enden. Schließlich können auch die genannten Kipplager vorgesehen sein. Diese ermöglichen ein Kippen der Trägerprofile um eine Achse mit Abstand zu einer mittleren Längsachse. Kipplager sind insbesondere vorgesehen für nicht rotationssymmetrische Trägerprofile.Advantageously, the carrier profiles are held in side bearings, pivot bearings or tilting bearings. Side bearings hold the carrier profiles especially at the ends. When trained as a pivot bearing carrier profiles can be rotated in the camps. The pivot bearings hold the carrier profiles preferably at the ends. Finally, the aforementioned tilting bearings can be provided. These allow tilting of the carrier profiles about an axis at a distance from a central longitudinal axis. Tipping bearings are particularly intended for non-rotationally symmetrical carrier profiles.
Die Trägerprofile können als Leisten, Stäbe oder Rohre ausgebildet sein, mit hohlem oder massivem Querschnitt. Auch kann sich der Querschnitt über die Länge der Trägerprofile ändern, etwa wie bei einer Tonnenform oder als ballige Oberfläche der Trägerprofile.The carrier profiles can be designed as strips, rods or tubes, with a hollow or solid cross-section. Also, the cross section can change over the length of the carrier profiles, such as in a barrel shape or as a spherical surface of the carrier profiles.
Nach einem weiteren Gedanken der Erfindung können zwei oder mehr Trägerprofile zur Bildung einer Trageinheit miteinander gekoppelt sein. Dabei kann eine getriebliche Kopplung von je zwei oder mehr Trägerprofilen, insbesondere zum gegenläufigen Verdrehen der Trägerprofile, vorgesehen sein. Durch die Kopplung ist eine besonders einfache Bedienung möglich. Bei getrieblicher Kopplung können durch Verstellung eines Federkörpers im Ergebnis beide Federkörper derselben Trageinheit eingestellt werden. Die Kopplung kann auch zur Sicherung eines gleichbleibenden Abstands benachbarter Trägerprofile dienen.According to a further aspect of the invention, two or more support profiles may be coupled together to form a support unit. In this case, a geared coupling of two or more carrier profiles, in particular for opposite rotation of the carrier profiles, be provided. By coupling a particularly simple operation is possible. In the case of a geared coupling, as a result, both spring bodies of the same carrying unit can be adjusted by adjusting a spring body. The coupling can also serve to ensure a constant spacing of adjacent carrier profiles.
Vorzugsweise bilden zwei oder mehr Trägerprofile eine gemeinsame, hinsichtlich der Biegesteifigkeit einstellbare Trageinheit. Insbesondere sind zwei Trägerprofile einer Trageinheit In einer im Wesentlichen in der gemeinsamen Ebene, vorzugsweise mit Abstand nebeneinander gehalten. Durch Verdrehen der Trägerprofile und senkrechten Druck auf dieselben können Querkräfte wirksam sein, die zu einer seitlichen Auslenkung der Trägerprofile führen. Bei Kopplung von zwei Trägerprofilen können die Querkräfte ausgeglichen werden, etwa durch gegenläufiges Verdrehen oder durch Kippen gleichartiger Trägerprofile innerhalb derselben Trageinheit.Preferably, two or more carrier profiles form a common, with respect to the bending stiffness adjustable support unit. In particular, two support profiles of a support unit are held in a substantially in the common plane, preferably at a distance from each other. By twisting the carrier profiles and vertical pressure on the same lateral forces can be effective, leading to a lateral deflection of the carrier profiles. When coupling two carrier profiles, the transverse forces can be compensated, for example by opposing twisting or by tilting similar carrier profiles within the same support unit.
Nach einem weiteren Gedanken der Erfindung können zwei Trägerprofile einer Trageinheit ineinander angeordnet oder zueinander konzentrisch angeordnet und gehalten sein. Beispielsweise ist ein dünneres, rohrförmiges Trägerprofil in einem dickeren, rohrförmigen Trägerprofil drehbar gehalten. Bei Verdrehen der beiden Trägerprofile relativ zueinander ergeben sich unterschiedliche Biegesteifigkeiten oder Widerstandsmomente. Durch gleichförmiges, gegenläufiges Verdrehen der belden Rohre wird die derart gebildete Trageinheit unter einer senkrecht wirkenden Kraft nicht seitlich ausweichen.According to a further aspect of the invention, two carrier profiles of a carrying unit can be arranged inside one another or arranged and held concentrically with one another. For example, a thinner, tubular carrier profile is rotatably supported in a thicker, tubular carrier profile. When the two carrier profiles are rotated relative to one another, different bending stiffnesses or moments of resistance result. By uniform, opposite rotation of Belden tubes, the support unit thus formed will not dodge laterally under a force acting vertically.
Vorteilhafterweise sind die Trägerprofile jeweils um eine Kippachse kippbar gehalten, wobei die Kippachsen am Rande des Querschnitts oder außerhalb des Querschnitts des betreffenden Trägerprofils verlaufen. Dabei können die beiden Trägerprofile im Bereich dieser Kippachsen miteinander gekoppelt sein, insbesondere mit zueinander fluchtenden Kippachsen. Im einfachsten Fall sind zwei Rechteckleisten über ein Scharnierband miteinander verbunden. Bei flach aufgeklappten Scharnier ergibt sich eine geringe Biegesteifigkeit. Durch Einklappen beider Leisten um jeweils den gleichen Winkel - bis zu einem hochkant stehenden Querschnitt - ist die Biegesteifigkeit vergrößerbar, und umgekehrt. Allgemein können als Trägerprofile innerhalb einer Trageinheit auch zwei Leisten oder Flachprofile vorgesehen sein, welche kippbar gehalten sind.Advantageously, the carrier profiles are each tilted about a tilting axis, wherein the tilting axes extend at the edge of the cross section or outside the cross section of the respective carrier profile. In this case, the two carrier profiles may be coupled together in the region of these tilting axes, in particular with mutually aligned tilting axes. In the simplest case, two rectangular strips are connected to each other via a hinge strap. When the hinge is folded flat, the bending stiffness is low. By folding both strips by the same angle - up to an upright cross-section - the bending stiffness is increased, and vice versa. In general, two strips or flat profiles can be provided as support profiles within a support unit, which are held tiltably.
Nach einem weiteren Gedanken der Erfindung sind zwei oder mehr Trägerprofile mit einem gemeinsamen Halter versehen, insbesondere zur Einhaltung eines bestimmten Abstands oder Abstandsbereiches der Trägerprofile voneinander. Bei den gemeinsamen Haltern kann es sich auch um gemeinsame Stützkörper zur Anbindung an den Rahmen oder an die Längsholme handeln. Möglich ist aber auch die Anordnung von Stützkörpern zuzüglich gesonderter Halter zur Verbindung der zwei oder mehr Trägerprofile miteinander. Die Halter sind so ausgebildet, dass die Trägerprofile zumindest im Bereich der Halter einen bestimmten Abstand beibehalten. Möglich ist auch die Verwendung nachgiebiger oder elastischer Halter, sodass ein bestimmter Abstandsbereich zwischen den Trägerprofilen eingehalten wird.According to a further aspect of the invention, two or more carrier profiles are provided with a common holder, in particular for maintaining a certain distance or distance range of the carrier profiles from each other. The common holders can also be common support bodies for connection to the frame or to the longitudinal bars. But it is also possible the arrangement of supporting bodies plus separate holder for connecting the two or more carrier profiles together. The holders are designed so that the carrier profiles maintain a certain distance, at least in the region of the holder. It is also possible to use compliant or elastic holders, so that a certain distance between the carrier profiles is maintained.
Die Halter können obere Auflageflächen aufweisen, etwa für eine Polsterung. Die Polsterung liegt dann zumindest im Bereich der Halter auf den Auflageflächen auf, im Übrigen auf den Trägerprofilen oder auf ggf. weiteren Elementen. Die Auflageflächen können auch federnd nachgiebig ausgebildet sein und so die Federcharakteristik der Trägerprofile oder der Trageinheit ergänzen.The holders may have upper bearing surfaces, such as for a padding. The padding is then at least in the area of the holder on the bearing surfaces, incidentally on the carrier profiles or possibly other elements. The bearing surfaces can also be formed resiliently and thus complement the spring characteristic of the carrier profiles or the support unit.
Vorteilhafterweise sind die Halter mit Federelementen bzw. Flügeln versehen, vorzugsweise mit Federwirkung in Richtung senkrecht zur gemeinsamen Ebene der Trägerprofile und/oder bezüglich des Abstands der Trägerprofile zueinander.Advantageously, the holders are provided with spring elements or wings, preferably with spring action in the direction perpendicular to the common plane of the carrier profiles and / or with respect to the spacing of the carrier profiles from each other.
Nach einem weiteren Gedanken der Erfindung sind die Trägerprofile durch Pultrusion hergestellte Stäbe oder Rohre. Beim Pultrudieren können in den Querschnitt des jeweiligen Trägerprofils insbesondere werkstoffbedingte Verstärkungen eingearbeitet werden, beispielsweise Kohlefasern anstelle von oder zusätzlich zu Glasfasern.According to a further aspect of the invention, the carrier profiles are bars or tubes made by pultrusion. When pultruding material-related reinforcements can be incorporated in the cross section of the respective carrier profile, for example carbon fibers instead of or in addition to glass fibers.
Eine weitere Ausführung der erfindungsgemäßen Unterfederung weist die Merkmale des Anspruchs 20 auf. Danach ist vorgesehen, dass die Trägerprofile zwei durch die Geometrie und/oder das Material gegebene Achsen unterschiedlicher Biegesteifigkeit aufweisen, wobei die beiden Achsen vorzugsweise senkrecht zueinander und insbesondere auch zur Längsachse senkrecht verlaufen, und wobei je zwei oder mehr Trägerprofile zur Bildung einer Trageinheit miteinander gekoppelt sind. Kombiniert werden somit die Achsen unterschiedlicher Biegesteifigkeit mit dem Gedanken der Kopplung von zwei oder mehr Trägerprofilen zu einer Trageinheit. Dabei sind die Trägerprofile innerhalb derselben Trageinheit vorzugsweise gegeneinander verdrehbar oder kippbar. Die Achsen unterschiedlicher Biegesteifigkeit können auch deckungsgleich oder parallel verlaufen.A further embodiment of the lower suspension according to the invention has the features of
Die zuletzt dargestellte erfindungsgemäße Unterfederung ist kombinierbar mit allen oder einigen der zuvor erläuterten Merkmale.The last illustrated suspension according to the invention can be combined with all or some of the features explained above.

Eine Unterfederung für eine Polsterung (Matratze) eines Bettes weist mehrere paarweise angeordnete, Trägerprofile 10, 11 auf, die in den Figuren rohrförmig ausgebildet sind, soweit nicht anders angegeben. Jedes Trägerprofil 10, 11 ist mit zwei orthogonalen Achsen s, w unterschiedlicher Biegesteifigkeit ausgebildet. Hierzu weisen die Trägerprofile 10, 11 jeweils mit Abstand zueinander vorgesehene Verstärkungen 12, 13 am Umfang auf. Die Verstärkungen 12, 13 können durch vom Trägerprofil im Übrigen abweichende Werkstoffe gebildet oder zusätzlich vorgesehen sein.A lower suspension for a padding (mattress) of a bed has a plurality of paired, carrier profiles 10, 11, which are tubular in the figures, unless otherwise stated.

Ebenfalls möglich ist eine Ausführung, bei der die Trägerprofile 10, 11 getrieblich oder auf andere Weise miteinander gekoppelt sind.Also possible is an embodiment in which the carrier profiles 10, 11 are coupled by means of a gear or in some other way.
In allen Ausführungsformen ist eine manuelle Verstellung der Trägerprofile vorgesehen. Möglich ist aber auch ein motorischer Antrieb.In all embodiments, a manual adjustment of the carrier profiles is provided. But it is also possible a motor drive.
Abweichend von den in den Figuren dargestellten Ausführungsbeispielen können auch Trägerprofile 10, 11 ohne Halter und Flügel vorgesehen sein.Notwithstanding the embodiments illustrated in the figures and carrier profiles 10, 11 may be provided without holder and wings.
Eine Minimallösung wäre die Verwendung nicht paarweiser Trägerprofile, sondern einzeln und mit Abstand zueinander angeordneter Trägerprofile, die vorzugsweise in entsprechenden Stützkörpern drehbar gelagert sind und insbesondere auch kleine Drehwinkel zulassen (wie in den Figuren dargestellt): Vorzugsweise liegt zwischen der härtesten und der weichsten Einstellung ein Drehwinkel von 90°, wie auch in den Figuren dargestellt.A minimal solution would be the use of non-paired carrier profiles, but individually and with spaced carrier profiles, which are preferably rotatably mounted in respective support bodies and in particular also allow small rotation angle (as shown in the figures): Preferably, between the hardest and the softest setting Angle of rotation of 90 °, as shown in the figures.
Die in den Figuren dargestellten Trägerprofile 10, 11 sind insbesondere durch Pultrudieren hergestellt und bestehen vorzugsweise aus Kunststoff mit eingebetteten Kohlefasern oder Glasfasern oder anderen eine bestimmte Steifigkeit definierenden Werkstoffen. So kann beispielsweise im Bereich der gezeichneten Verstärkungen 12, 13 Kohlefaser vorgesehen sein, während die Trägerprofile 10, 11 im Übrigen (nur) glasfaserverstärkt sind. Durch die verschiedenen Eigenschaften der genannten Verstärkungswerkstoffe ergeben sich die unterschiedlichen Biegesteifigkeiten in Richtung der Achsen s und w, siehe
Die in den Fig. 1a bis 3d dargestellten Verstärkungen erstrecken sich im Wesentlichen über die volle Dicke von Wandungen der rohrförmigen Trägerprofile 10, 11. Zugleich erstrecken sich die Verstärkungen 12, 13 in Umfangsrichtung jeweils über etwa 30° bis 90°, vorzugsweise etwa 60°. Die Verstärkungen können aber auch in anderer Weise ausgebildet und/oder eingebettet sein, etwa als eine oder mehrere rundstabförmige Einlagen. Schließlich können die Verstärkungen auch innen oder außen auf die Trägerprofile aufgebracht sein.The reinforcements shown in FIGS. 1a to 3d extend essentially over the full thickness of walls of the tubular carrier profiles 10, 11.
