Abstract

A slatted base for furniture for lying on has two longitudinally running, essentially parallel longitudinal supports (50) with mutually facing inner sides (32). The slatted base also has a plurality of spaced-apart slats (10, 71, 72) which are arranged transversely to the longitudinal supports (50) and together form a bearing surface for a mattress. The slats (10, 71, 72) are connected to the longitudinal supports (50) by means of [sic] essentially two-legged leaf-spring elements (20, 81, 82), in each case one leg (22) of a leaf-spring element (20) being fitted on one of the slats (10) and the other leg (23) of said leaf-spring element (20) being fitted on the inner side (32) of one of the longitudinal supports (50). The slatted base, on the one hand, is of low overall height and is thus suitable for positioning in a framework of a piece of furniture for lying on. The slatted base, on the other hand, ensures a comparatively high level of resilient deflection for the slats (10, 71, 72), in particular also in the region of the longitudinal supports (50) bearing the slats (10, 71, 72).

Darstellung der ErfindungPresentation of the invention

Aufgabe der vorliegenden Erfindung ist die Angabe eines Lattenrosts, der einerseits eine geringe Bauhöhe aufweist und andrerseits einen grossen Federweg für die Latten, insbesondere auch im Bereich der die Latten tragenden Längsträger, gewährleistet. The object of the present invention is to provide a slatted base, which on the one hand has a low overall height and, on the other hand, a large spring travel for the slats, in particular also guaranteed in the area of the longitudinal beams carrying the slats.

Die Lösung der Aufgabe ist durch die Merkmale des Anspruchs 1 definiert. Gemäss der Erfindung weist ein Lattenrost für Liegemöbel zwei in Längsrichtung verlaufende, im Wesentlichen parallele Längsträger mit einander zugewandten Innenseiten auf. Die Bezeichnungen "innen" und "aussen" sind im vorliegenden Zusammenhang stets in Bezug auf den Lattenrost zu verstehen. Der Lattenrost weist weiter eine Mehrzahl von in gegenseitigem Abstand quer zu den Längsträgern angeordneten Latten auf, die gesamthaft eine Auflagefläche für eine Matratze bilden. Die Latten sind mittels von im Wesentlichen zweischenkligen Blattfederelementen mit den Längsträgern verbunden, wobei jeweils ein Schenkel eines Blattfederelementes an einer der Latten und der andere Schenkel dieses Blattfederelementes an der Innenseite eines der Längsträger angebracht ist. The solution to the problem is defined by the features of claim 1. According to the Invention has a slatted base for reclining furniture two in the longitudinal direction, in Essentially parallel longitudinal beams with mutually facing inner sides. The In the present context, terms "inside" and "outside" are always related to understand the slatted frame. The slatted frame further has a plurality of in mutual distance across the longitudinal beams arranged slats, the whole form a support surface for a mattress. The slats are essentially by means of two-leg leaf spring elements connected to the side members, one each Leg of a leaf spring element on one of the slats and the other leg of this Leaf spring element is attached to the inside of one of the side members.

Unter einem zweischenkligen Blattfederelement ist im Zusammenhang mit der vorliegenden Beschreibung und den Patentansprüchen ein Federelement zu verstehen, das zwei Schenkel nach Art von Blattfedern aufweist, welche eine blatt- oder bandförmige, im Wesentlichen flache Struktur haben.Under a two-leg leaf spring element is in connection with the present Description and the claims to understand a spring element, the two Leg in the manner of leaf springs, which has a leaf or ribbon-shaped, essentially have a flat structure.

Indem gemäss der Erfindung die Latten mittels flachen, blattfederförmigen Elementen, die an der Seitenfläche der Längsträger angebracht sind, mit den Längsträgern verbunden bzw. an diesen getragen werden, benötigen die Verbindungselemente in Richtung der Federbewegung, d.h. im Wesentlichen quer zur Trägerlängsrichtung und quer zur Lattenlängsrichtung, bloss wenig Platz. Der durch diese flachen Blattfederelemente im Bereich der Längsträger in Richtung der Federbewegung benötigte Platz entspricht im Wesentlichen der Dicke der an den Latten angebrachten Federschenkel. Aufgrund des geringen Platzbedarfs steht ein vergleichsweise grosser Federweg zur Verfügung. Dieser geringe Platzbedarf ist insbesondere bei Lattenrostkonstruktionen vorteilhaft, bei denen die an den Latten angebrachten Federschenkel teilweise zwischen den Latten und den Längsträgern angeordnet sind und durch Belastungen des Lattenrosts auf letztere hinuntergedrückt werden.By according to the invention, the slats by means of flat, leaf spring-shaped elements are attached to the side surface of the side members, connected to the side members or worn on these, the connecting elements need in the direction of Spring movement, i.e. essentially transverse to the longitudinal direction of the beam and transverse to the longitudinal direction of the slats, only little space. The flat leaf spring elements in the area the space required in the direction of the spring movement essentially corresponds the thickness of the spring legs attached to the slats. Because of the low A comparatively large spring travel is available for space requirements. This little one Space requirement is particularly advantageous in the case of slatted frame constructions in which the on Slat-mounted spring legs partially between the slats and the side members are arranged and pressed down by loads on the slatted frame become.

Gemäss einer bevorzugten Ausführungsart der Erfindung ist bei einem Lattenrost wenigstens eines der Blattfederelemente derart angeordnet, dass sein am Längsträger angebrachter Federschenkel sich vom Bereich seiner Anbringungsstelle am Längsträger aus in einer bezüglich der durch die beiden Längsträger definierten Ebene zu der mit dem Blattfederelement verbundenen Latte hin geneigten Richtung erstreckt. Vorzugsweise sind sogar sämtliche Blattfederelemente auf diese Art angeordnet.According to a preferred embodiment of the invention, there is at least one slatted frame one of the leaf spring elements arranged such that its attached to the side member Spring leg in from the area of its attachment point on the side member a with respect to the plane defined by the two longitudinal beams to that with the leaf spring element connected slat extends towards the inclined direction. Even preferred all leaf spring elements arranged in this way.

Üblicherweise ist der Lattenrost bzw. die durch die beiden Längsträger definierte Ebene des Lattenrosts im Wesentlichen horizontal angeordnet. Der Federschenkel erstreckt sich in diesem Fall im Bereich des Längsträgers vom Längsträger aus schräg nach oben. Dadurch wird bei einer horizontalen Anordnung des Lattenrosts die Kraft von den durch die Latten im Wesentlichen senkrecht von oben belasteten Federelementen auf die beiden Längsträger nicht wie üblich entweder in horizontaler oder in vertikaler Richtung, sondern schräg nach unten eingeleitet. Diese geometrische Anordnung der Latten, der Blattfederelemente und der Längsträger relativ zueinander ist der vorliegenden Situation besonders gut angepasst. Vorzugsweise beträgt der Neigungswinkel zwischen den Federschenkeln und der durch die beiden Längsträger definierten (üblicherweise horizontalen) Ebene im Bereich der Anbringungsstellen der Federschenkel an den Längsträgern zwischen 5 und 80 Grad, wobei Neigungswinkel zwischen 20 und 45 Grad, insbesondere Neigungswinkel von ungefähr 30 Grad besonders bevorzugt werden.Usually the slatted frame or the plane defined by the two longitudinal beams the slatted frame is arranged essentially horizontally. The spring leg extends in this case in the area of the side member from the side member diagonally upwards. Thereby with a horizontal arrangement of the slatted frame, the force of the Slats essentially perpendicular to the spring elements loaded from above on the two Side members not, as usual, in either the horizontal or vertical direction, but instead introduced diagonally downwards. This geometrical arrangement of the slats, the leaf spring elements and the side member relative to each other is special in the present situation well adapted. The angle of inclination between the spring legs is preferably and the (usually horizontal) defined by the two side members Level in the area of the attachment points of the spring legs on the side members between 5 and 80 degrees, with angles of inclination between 20 and 45 degrees, in particular angles of inclination of about 30 degrees are particularly preferred.

Vorzugsweise weist ein Blattfederelement eines erfindungsgemässen Lattenrosts eine im Wesentlichen U-förmige Gestalt auf, mit zwei Schenkelpartien und einer diese beiden Schenkelpartien verbindenden Stegpartie. Dabei ist das Federelement bevorzugterweise derart am Lattenrost montiert, dass die Stegpartie im Innenraum des Lattenrosts (d.h. zwischen den beiden Längsträgern) angeordnet ist, so dass sich die beiden Schenkelpartien von der Stegpartie aus nach aussen hin zu ihren Anbringungsstellen an der Latte beziehungsweise an der Innenseite des Längsträgers erstrecken.A leaf spring element of a slatted base according to the invention preferably has an im Mainly U-shaped shape, with two thighs and one of these two Bridge section connecting thighs. The spring element is preferably mounted on the slatted frame in such a way that the web section in the interior of the slatted frame (i.e. between the two longitudinal beams) is arranged so that the two leg parts from the bridge area outwards to their attachment points on the crossbar or extend on the inside of the side member.

Die Blattfederelemente eines erfindungsgemässen Lattenrosts können aus glasfaserverstärktem Kunststoff gefertigt sein, wobei die Glasfasern wenigstens teilweise unidirektional, vorzugsweise sogar vollständig unidirektional in Längsrichtung der Blattfederelemente verlaufend angeordnet sein können. Blattfederelemente aus glasfaserverstärktem Kunststoff zeichnen sich durch eine besonders grosse Lebensdauer aus. Sie erlahmen auch nach einem langjährigen Dauergebrauch nicht. Als Alternative zu Blattfederelementen aus glasfaserverstärktem Kunststoff können die Federelemente auch aus Federstahlblech oder aus anderen für Blattfedern geeigneten Materialien gefertigt sein.The leaf spring elements of a slatted frame according to the invention can be made of glass fiber reinforced Be made of plastic, the glass fibers being at least partially unidirectional, preferably even completely unidirectionally in the longitudinal direction of the leaf spring elements can be arranged progressively. Leaf spring elements made of glass fiber reinforced plastic are characterized by a particularly long service life. They also weaken after many years of continuous use. As an alternative to leaf spring elements Glass-fiber reinforced plastic can also be made of spring steel sheet or spring elements be made of other materials suitable for leaf springs.

Die Innenseite eines Längsträgers eines erfindungsgemässen Lattenrosts ist vorzugsweise mit Federhalterungsmitteln versehen, die zum Anbringen von einem oder mehreren der Blattfederelemente ausgebildet sind. Die Federhalterungsmittel können als integrale Bestandteile des Längsträgers ausgebildet sein, oder sie können als separate Teile an der Innenseite des Längsträgers angebracht sein. Sie können aus Kunststoff, aus Federstahlblech, aus Aluminium oder aus anderen geeigneten Materialien gefertigt sein. The inside of a side member of a slatted frame according to the invention is preferred provided with spring retainer means for attaching one or more of the Leaf spring elements are formed. The spring retainer means can be an integral part be formed of the side member, or they can be as separate parts on the Be attached to the inside of the side member. They can be made of plastic, spring steel sheet, be made of aluminum or other suitable materials.

Gemäss einer bevorzugten Ausführungsart der Erfindung umfassen die Federhalterungsmittel ein an der Innenseite des einen Längsträgers angeordnetes Hohlprofil, vorzugsweise ein Aluminiumstrangprofil, in dessen dem anderen Längsträger zugewandter Profilwand eine zur Aufnahme der an diesen Federhalterungsmitteln anzubringenden Schenkelenden der Blattfederelemente geeignete Nut ausgebildet ist. Dabei kann die dem anderen Längsträger zugewandte Profilwand des Hohlprofils im Wesentlichen eben sein und bezüglich der durch die beiden Längsträger definierten (üblicherweise horizontalen) Ebene einen Winkel einschliessen, der 10 - 85 Grad, vorzugsweise 45 - 70 Grad, insbesondere ungefähr 60 Grad beträgt, wobei die Nut in der Wand an der Innenseite des Profils vorzugsweise rechtwinklig zur Oberfläche dieser profilinnenseitigen Wand ausgebildet ist. Bei einem Winkel von ungefähr 60 Grad erstreckt sich dann ein in der Nut aufgenommener Federschenkel mit einem Winkel von ungefähr 30 Grad bezüglich der Horizontalen vom Hohlprofil bzw. vom Längsträger weg, an dem er angebracht ist.According to a preferred embodiment of the invention, the spring holding means comprise a hollow profile arranged on the inside of the one longitudinal beam, preferably an aluminum extruded profile, in the profile wall facing the other side member one for receiving the leg ends to be attached to these spring holding means suitable groove is formed of the leaf spring elements. The other side member can facing profile wall of the hollow profile be substantially flat and with respect to an angle defined by the two longitudinal beams (usually horizontal) include the 10-85 degrees, preferably 45-70 degrees, particularly approximately 60 degrees, the groove in the wall on the inside of the profile is preferred is formed at right angles to the surface of this inside wall of the profile. At a An angle of approximately 60 degrees then extends in a groove accommodated in the groove Spring legs with an angle of approximately 30 degrees with respect to the horizontal from Hollow profile or away from the side member to which it is attached.

Vorzugsweise ist der Lattenrost weiter mit einem am Kopfende und/oder am Fussende des Lattenrosts quer zu den Längsträgern angeordneten Hohlprofil versehen, das einen gleichen Querschnitt wie das am Längsträger angeordnete Hohlprofil aufweist und mit einer zur Aufnahme eines Handgriffs geeigneten Nut versehen ist. Dieser Handgriff z.B. zum Hochziehen einer verstellbaren Lattenrostpartie kann am kopfseitigen Ende des Lattenrosts vorgesehen sein.The slatted frame is preferably further with one at the head end and / or at the foot end of the slatted frame arranged transversely to the longitudinal beams, the one has the same cross section as the hollow profile arranged on the side member and with a groove suitable for receiving a handle is provided. This handle e.g. to pull up an adjustable slatted frame section at the head end of the Slatted frame can be provided.

Gemäss einer weiteren bevorzugten Ausführungsart der Erfindung sind wenigstens zwei benachbarte Latten des Lattenrosts mittels Verbindungsmitteln miteinander verbunden, um eine für Liegemöbel vorteilhafte Kopplung zwischen benachbarten Latten zu schaffen. Ein solcher Lattenrost kann weiter mit einem an den Verbindungsmitteln anbringbaren Matratzenhalter versehen sein.According to a further preferred embodiment of the invention, at least two adjacent slats of the slatted frame are connected to one another by means of connecting means, to create a coupling between adjacent slats that is advantageous for reclining furniture. Such a slatted frame can also be attached to the connecting means Mattress holder must be provided.

Gemäss einer bevorzugten Ausführungsart der Erfindung umfasst ein Längsträger eines Lattenrosts einen Holm aus Schichtholz, wobei der Längsträger insgesamt und insbesondere der Holm derart bemessen sind, dass die Trägerhöhe auf der ganzen Länge kleiner als ungefähr 50 mm, vorzugsweise kleiner als ungefähr 45 mm, insbesondere sogar kleiner als ungefähr 40 mm ist. Ein Holm aus Holz vermittelt einen besonders für Liegemöbel bevorzugten warmen, gemütlichen Eindruck. Trotzdem eignet er sich aufgrund der kleinen Bauhöhe gut für einen zum Einlegen in ein Möbelgestell vorgesehenen Lattenrost. Zum Zwecke einer strukturellen Versteifung des Holms kann dieser mit einem oder mehreren an seiner Oberseite und/oder an seiner Unterseite angebrachten Verstärkungsstreifen versehen sein, der oder die in Holmenlängsrichtung verlaufende Kohlefasern (auch als Carbonfasern bezeichnet) aufweisen. Dadurch wird die Herstellung von steifen Holzholmen mit einer besonders kleinen Bauhöhe ermöglicht. Dieser Aspekt der Erfindung erweist sich auch ohne die Verwendung von im Wesentlichen zweischenkligen Blattfederelementen zur Verbindung der Latten mit den Längsträgern als vorteilhaft, wenn die Herstellung eines Lattenrostes mit einer möglichst geringen Einbauhöhe gewünscht wird.According to a preferred embodiment of the invention, a side member comprises one Slatted frame a spar made of plywood, with the side member overall and in particular the spar are dimensioned such that the beam height is less than the entire length about 50 mm, preferably less than about 45 mm, especially even less than is about 40 mm. A wooden spar conveys one that is particularly preferred for reclining furniture warm, cozy impression. Nevertheless, it is suitable due to the small height good for a slatted frame intended for insertion in a furniture frame. For the purpose A structural stiffening of the spar can be done with one or more on its Provide top and / or reinforcement strips attached to its underside be the or the carbon fibers running in the longitudinal direction of the spar (also as carbon fibers designated). This makes the manufacture of stiff wooden spars with a allows a particularly small overall height. This aspect of the invention also proves without the use of essentially two-leg leaf spring elements for connection the slats with the side members as advantageous if the production of a Slatted frame with the lowest possible installation height is desired.

Es sind jedoch auch andere Varianten von Längsträgern möglich. So kann z.B. ein einziges Hohlprofil für den Träger vorgesehen sein, das derart ausgebildet ist, dass es gleichzeitig auch mit geeigneten Anbringungsstellen zum Anbringen der Blattfederelemente versehen ist. Oder der Träger kann einen Schichtholzholm mit niedriger Bauhöhe und ohne Verstärkungsstreifen aus Kohle- oder anderen geeigneten Fasern aufweisen, wobei jedoch an der Innenseite des Holms ein Hohlprofil derart angeordnet ist, dass es zum einen zu einer Versteifung und Verstärkung der aus dem Holm und dem Hohlprofil gebildeten Trägerstruktur beiträgt und zum andern zur Aufnahme der am Träger anzubringenden Blattfederelemente dient.However, other variants of side members are also possible. For example, a single one Hollow profile can be provided for the carrier, which is designed such that it is simultaneously also provided with suitable attachment points for attaching the leaf spring elements is. Or the girder can be a plywood spar with a low construction height and without reinforcement strips of carbon or other suitable fibers, but at the A hollow profile is arranged on the inside of the spar in such a way that, on the one hand, it provides stiffening and reinforcement of the support structure formed from the spar and the hollow profile contributes and to the other to accommodate the leaf spring elements to be attached to the carrier serves.

Vorzugsweise weist ein einen Holm aus Schichtholz umfassender Längsträger eines erfindungsgemässen Lattenrosts eine erste Partie auf, in welcher der Holm im Wesentlichen auf der ganzen Länge mit einem an seiner Innenseite angebrachten ersten einstückigen Hohlprofil, das als Federhalterungsmittel ausgebildet ist, fest verbunden ist. Der Längsträger umfasst eine zweite Partie, in welcher auf der Innenseite des Holmes ein zweites einstückiges Hohlprofil, das wiederum als Federhalterungsmittel ausgebildet ist, angeordnet ist. Das zweite Hohlprofil ist um eine im Wesentlichen in der durch die beiden Längsträger definierten Ebene liegende Querachse herum schwenkbar am ersten Hohlprofil angelenkt. Der zweite Längsträger des Lattenrosts ist analog ausgebildet, so dass die mit dem zweiten Hohlprofil verbundenen Latten eine bezüglich der mit dem ersten Hohlprofil verbundenen Latten verstellbare Lattenrostpartie bilden. Die bezüglich den stationären, mit der ersten Trägerpartie verbundenen Latten verstellbare Lattenrostpartie kann z.B. zur Gewährleistung einer Kopfhochlagerung verwendet werden.Preferably, a longitudinal beam comprising a spar made of plywood has one slatted frame according to the invention in a first batch in which the spar in Essentially along the entire length with a first attached to its inside integral hollow profile, which is designed as a spring holder means, is firmly connected. The side member comprises a second section, in which on the inside of the spar second one-piece hollow profile, which in turn is designed as a spring holder means, is arranged. The second hollow section is essentially one by the two Longitudinal axis defined plane lying transverse axis pivotable on the first Articulated hollow profile. The second side member of the slatted frame is designed analogously, so that the slats connected to the second hollow profile are one with respect to those with the first Hollow profile connected slats form adjustable slatted frame section. The regarding the stationary slatted frame section adjustable with the first beam section can e.g. can be used to ensure head positioning.

Gemäss einer weiteren bevorzugten Erfindungsvariante ist ein Lattenrost mit zwei in Längsrichtung verlaufenden, im Wesentlichen parallelen Längsträgern und einer Mehrzahl von in gegenseitigem Abstand und quer zu den Längsträgernangeordneten Latten, die gesamthaft eine Auflagefläche für eine Matratze bilden, weiter mit einer Stützfederanordnung versehen, welche wenigstens ein Stützfederelement umfasst, das unterhalb von wenigstens einer Latte derart angeordnet ist, dass es die Latte in einem mittleren Bereich zwischen den Längsträgern mittels Federkraft abstützt. Dabei ist das Stützfederelement entweder auf wenigstens einem der beiden Längsträger oder auf einer an den beiden Längsträgern angebrachten Querstrebe gelagert und stützt die Latte somit indirekt auf diese Lagerstelle ab. Eine solche Stützfederanordnung ermöglicht eine zusätzliche federnde bzw. elastische Abstützung der Latten in einer mittleren Zone des Lattenrosts. Sie wird deshalb nachfolgend wird nachfolgend auch als Mittelzonenverstärkung bezeichnet. Es leuchtet ein; dass dieser Aspekt der Erfindung nicht zwingend im Zusammenhang mit der Verwendung von im Wesentlichen zweischenkligen Blattfederelementen zur Verbindung der Latten mit den Längsträgern eingesetzt werden muss.According to a further preferred variant of the invention, a slatted frame with two in Longitudinal, substantially parallel side members and a plurality of slats arranged at a distance from one another and transversely to the longitudinal beams form a total support surface for a mattress, continue with one Support spring arrangement provided, which comprises at least one support spring element, the is arranged below at least one slat so that it is the slat in one middle area between the side members is supported by spring force. It is Support spring element either on at least one of the two longitudinal beams or on one mounted on the two cross members attached to the crossbar and thus supports the crossbar indirectly on this depository. Such a support spring arrangement enables one additional resilient or elastic support of the slats in a central zone of the Slatted base. It is therefore also referred to below as Central zone reinforcement. It makes sense; that this aspect of the invention is not mandatory in connection with the use of essentially two-legged Leaf spring elements are used to connect the slats to the side members got to.

Eine Stützfederanordnung (bzw. eine Mittelzonenverstärkung) für einen Lattenrost umfasst vorzugsweise wenigstens ein Stützfederelement, das derart ausgebildet ist, dass es unterhalb von wenigstens einer Latte des Lattenrosts solcherart angeordnet werden kann, dass es die Latte in einem mittleren Bereich zwischen zwei Längsträgern des Lattenrosts mittels Federkraft abstützt, wobei das Stützfederelement entweder auf wenigstens einem der beiden Längsträger oder auf einer an den beiden Längsträgern angebrachten Querstrebe gelagert sein kann und somit die Latte indirekt auf diese Lagerstelle abstüzten kann. Das Stützfederelement kann als Blattfederelement ausgebildet sein, wobei dieses Blattfederelement zwei unter einem Winkel zueinander angeordnete, längliche Blattfederarme umfassen kann, so dass das Stützfederelement im Wesentlichen V-fömig ausgebildet ist. Ein solches V-förmig ausgebildetes Blattfederelement kann derart am Lattenrost angeordnet sein, dass es im Bereich des Verbindungswinkels zwischen den beiden Federarmen auf einer Querstrebe des Lattenrosts gelagert ist und die Latte im Bereich der vom Verbindungswinkel entfernten Längsende der Arme von unten stützt. Grundsätzlich sind jedoch auch anders ausgebildete und/oder anders am Lattenrost angeordnete Stützfederelemente möglich. Eine Mittelzonenverstärkung kann beispielsweise auch eine auf einer Querstrebe des Lattenrosts gelagerte und eine Latte von unten stützende Spiralfeder umfassen.A support spring arrangement (or a central zone reinforcement) for a slatted frame comprises preferably at least one support spring element which is designed such that it can be arranged below at least one slat of the slatted frame in such a way that there is the slat in a middle area between two side members of the slatted frame supported by spring force, the support spring element either on at least one of the two side members or on one attached to the two side members Cross strut can be stored and thus indirectly support the crossbar on this bearing point can. The support spring element can be designed as a leaf spring element, this Leaf spring element two, elongated arranged at an angle to each other Leaf spring arms can include, so that the support spring element is substantially V-shaped is trained. Such a V-shaped leaf spring element can be on Slatted base should be arranged so that it is in the area of the connection angle between the two spring arms is mounted on a cross strut of the slatted frame and the slat in Support area of the longitudinal end of the arms distant from the connection angle from below. Basically, however, there are also other trained and / or different slatted frames arranged support spring elements possible. A central zone reinforcement can for example, one on a cross strut of the slatted frame and one slat from below support spiral spring.

Vorzugsweise umfasst eine Stützfederanordnung (bzw. eine Mittelzonenverstärkung) für einen Lattenrost weiter Mittel für eine wahlweise Einstellung der Federkraft des Stützfederelementes. Im Falle einer Stützfederanordnung mit einem V-förmig ausgebildeten Stützfederelement können diese Federeinstellmittel z.B. eine Stellschraube umfassen, mittels welcher der Winkel zwischen den beiden Federamen verstellt werden kann, um diese Federarme vorzuspannen und somit die die Latte stützende Federkraft des Stützfederelementes einzustellen. Grundsätzlich können jedoch auch andere geeignete Mittel zum Einstellen der Federkraft vorgesehen sein. So ist z.B. auch die Verwendung einer Vorrichtung zur Verstellung der Auflagerstelle des Stützfederelementes an der Querstrebe bzw. an den Längsträgern des Lattenrosts möglich, um die Vorspannung des Sützfederelementes wahlweise zu verändern.Preferably comprises a support spring arrangement (or a central zone reinforcement) for a slatted base means for an optional adjustment of the spring force of the Support spring element. In the case of a support spring arrangement with a V-shaped trained support spring element, these spring adjusting means can e.g. a set screw include, by means of which the angle between the two nicknames are adjusted can to bias these spring arms and thus the spring force supporting the crossbar Adjust the support spring element. In principle, however, other suitable ones can also be used Means for adjusting the spring force may be provided. For example, also use a device for adjusting the support point of the support spring element on the Cross strut or on the longitudinal beams of the slatted frame possible to the pretension of the Support spring element to change optionally.

In Fig. 1 ist beispielhaft eine Verbindungsanordnung zur Verbindung einer Latte 10 mit dem einen Längsträger 50 im Querschnitt dargestellt. In unterbrochenen Linien ist ebenfalls eine ausserhalb der Schnittebene liegende Verbindungsstrebe 52 zwischen den beiden Längsträgern 50 dargestellt. Das an der Innenseite des Trägerholms 40 fest angebrachte erste Hohlprofil 30 weist eine im Wesentlichen ebene, dem anderen Längsträger zugewandte Profilwand 32 auf, die nachfolgend als profilinnenseitige Wand 32 des Hohlprofils 30 bezeichnet wird. Diese innenseitige Wand 32 des Hohlprofils 30 bildet gleichzeitig die Innenseite 32 des den Holm 40 und das Aluminiumstrangprofil 30 umfassenden Längsträgers 50. Die profilinnenseitige Wand 32 des Hohlprofils 30 (bzw. die Innenseite 32 des Längsträgers 50) ist bezüglich der Horizontalen 54 (d.h. bezüglich der durch die beiden Längsträger 50 definierten, in Fig. 1 mit einer unterbrochenen Linie dargestellten Ebene 54) gegen oben hin nach aussen geneigt, wobei der zwischen der Wand 32 an der Profilinnenseite und der Horizontalen 54 eingeschlossene Winkel α ungefähr 60 Grad beträgt.In Fig. 1 is an example of a connection arrangement for connecting a crossbar 10 with the a side member 50 shown in cross section. In broken lines is also a connecting strut 52 lying outside the sectional plane between the two Side members 50 shown. That firmly attached to the inside of the beam 40 The first hollow profile 30 has an essentially flat, facing the other longitudinal beam Profile wall 32, which subsequently as the inside wall 32 of the hollow profile 30 is referred to. This inside wall 32 of the hollow profile 30 also forms the Inside 32 of the spar 40 and the aluminum extrusion 30 comprising Side member 50. The inside wall 32 of the hollow section 30 (or the inside 32 of the side member 50) is with respect to the horizontal 54 (i.e. with respect to that through the two Side members 50 defined plane shown in Fig. 1 with a broken line 54) inclined outwards towards the top, the between the wall 32 on the Profile inside and the horizontal 54 included angle α about 60 degrees is.

In der Wand 32 an der Innenseite des Hohlprofils 30 ist eine in Profillängsrichtung verlaufende Nut 35 zur Aufnahme der Federschenkel 23 der Blattfederelemente 20 ausgebildet, wobei der Nutquerschnitt im Wesentlichen rechtwinklig zur Oberfläche der profilinnenseitigen Wand 32 verläuft.In the wall 32 on the inside of the hollow profile 30 is one in the longitudinal direction of the profile extending groove 35 for receiving the spring legs 23 of the leaf spring elements 20th formed, the groove cross section substantially perpendicular to the surface of the Wall 32 on the inside of the profile.

Das in der Querschnittdarstellung der Fig. 1 dargestellte Blattfederelement 20 hat eine im Wesentlichen U-förmige Gestalt, mit zwei Schenkelpartien 22, 23 und einer diese beiden Schenkelpartien 22, 23 verbindenden Stegpartie 21. Das Blattfederelement 20 ist aus glasfaserverstärktem Kunststoff gefertigt, wobei die Glasfasern wenigstens teilweise unidirektional in Längsrichtung des Blattfederelementes 20 verlaufend angeordnet sind.The leaf spring element 20 shown in the cross-sectional view of FIG. 1 has a Essentially U-shaped shape, with two leg parts 22, 23 and one of these two Leg portions 22, 23 connecting web portion 21. The leaf spring element 20 is made glass fiber reinforced plastic, the glass fibers at least partially unidirectional are arranged extending in the longitudinal direction of the leaf spring element 20.

Das Blattfederelement 20 ist derart am Lattenrost angeordnet, dass die Stegpartie 21 im Innenraum des Lattenrosts, d.h. zwischen den beiden parallelen Längsträgern 50, liegt. Die am Längsträger 50 angebrachte Schenkelpartie 23 erstreckt sich von der Stegpartie 21 aus schräg nach aussen und unten, wobei das Ende dieses Federschenkels 23 in der in der profilinnenseitigen Wand 32 ausgebildeten Nut 35 derart aufgenommen ist, dass der Neigungswinkel β dieses Federschenkels 23 bezüglich der Horizontalen 54 im Bereich seiner Anbringungsstelle an der profilinnenseitigen Wand 32 ungefähr 30 Grad beträgt. Bei der in Fig. 1 und Fig. 2 dargestellten Ausführungsart der Erfindung ist dieses Federschenkelende mit einer Verdickung 25 aus einem elastischem Material versehen, um ein sattes Einstecken des Federschenkelendes in die Nut 35 zu ermöglichen.The leaf spring element 20 is arranged on the slatted frame in such a way that the web portion 21 in the Interior of the slatted frame, i.e. lies between the two parallel longitudinal beams 50. The Leg portion 23 attached to the longitudinal beam 50 extends from the web portion 21 from obliquely outwards and downwards, the end of this spring leg 23 in the in the inside wall 32 formed groove 35 is received such that the Inclination angle β of this spring leg 23 with respect to the horizontal 54 in the area its location on the inside wall 32 of the profile is approximately 30 degrees. at the embodiment of the invention shown in FIGS. 1 and 2 is this Spring leg end with a thickening 25 made of an elastic material to to allow a tight insertion of the spring leg end into the groove 35.

Es sind jedoch auch andere Varianten zur Anbringung der Federelemente am Längsträger möglich. So kann beispielsweise das Federschenkelende in seinem Endbereich um ca. 180 Grad gebogen sein, damit das umgekrümmte Ende eine Rückhaltefeder bildet, welche in eine mit einem randseitigen Vorsprung versehene Nut derart eingerastet werden kann, dass die hinter dem Vorsprung eingerastete Rückhaltefeder ein Herausziehen des Federschenkels aus der Nut verhindert.However, there are also other variants for attaching the spring elements to the side member possible. For example, the end of the spring leg can be approx. Be bent 180 degrees so that the curved end forms a retaining spring, which can be snapped into a groove provided with an edge projection, that the retaining spring engaged behind the projection pulls out the spring leg prevented from the groove.

Die an der Latte 10 angebrachte Schenkelpartie 22 erstreckt sich von der Stegpartie 21 aus schräg nach aussen und oben.

Die Stützelemente 181, 182 sind derart an den Armen 166, 167 der Stützfeder 163 angeordnet, dass sie sich im Wesentlichen parallel zur Längsrichtung des Lattenrosts (d.h. quer zu den Latten 110, 111, 171, 172) erstrecken und die beiden Latten 171, 172 des über der Stützfeder 163 angeordneten Lattenpaares von unten her stützen, wobei die Stützelemente 181, 182 derart ausgebildet sind, dass die Latten 171, 172 problemlos auf ihnen gleiten können.The essentially V-shaped support spring 163 lies with its two Connection arms 166, 167 each on one of the support surfaces 176, 177 in such a way that the two arms 166, 167 of the support spring 163 from the the longitudinal edges of the recess 170 defining support surfaces 176, 177 each upward and outward in Extend towards the side edges of the slatted frame. At the outer ends of the Arms 166, 167 each have an elongated support element 181, 182 attached. The support elements 181, 182 are arranged on the arms 166, 167 of the support spring 163 such that they are substantially parallel to the longitudinal direction of the slatted frame (i.e. across the slats 110, 111, 171, 172) and the two slats 171, 172 of the support spring 163 support the arranged pair of slats from below, the support elements 181, 182 are designed such that the slats 171, 172 can slide on them without any problems.

Die Verbindungspartie zwischen den beiden Armen 166, 167 der Stützfeder 163 ist unter dem Deckelteil 175 und der Stellschraube 165 hindurch geführt, wobei die Krümmung dieser Verbindungspartie derart bemessen ist, dass die Stützfeder 163 zwischen den beiden Stützflächen 176, 177 zwar unter der Stellschraube 165 hindurch führt, jedoch nicht bis auf den Boden des Alumiumhohlprofils 153 hinunter reicht. Mittels der Stellschraube 165 kann nun die Verbindungspartie der Stützfeder 163 bezüglich dem Aluminiumprofil 153, auf dem die Stützfeder 163 gelagert ist, wahlweise von oben belastet und nach unten gedrückt oder wieder entlastet werden. Wenn die Stellschraube 165 nach unten geschraubt und dadurch die Verbindungspartie der Stützfeder 163 nach unten, zum Boden des Aluminiumprofils 153 hin gedrückt wird, wird der Krümmungsradius der Verbindungspartie zwischen den beiden Armen 166, 167 der Stützfeder 163 verkleinert. Dadurch werden die Aussenenden der beiden Arme 166, 167 der Stützfeder 163 angehoben bzw. verstärkt nach oben gedrückt, so dass die an diesen Aussenenden angebrachten Stützelemente 181, 182 eine grössere Stützkraft auf die über ihnen angeordneten Latten 171, 172 ausüben. Umgekehrt wird die Stützkraft der Stützelemente 181, 182 auf die Latten 171, 172 verringert, wenn die Stellschraube 165 nach oben geschraubt und dadurch der Krümmungsradius der Verbindungspartie zwischen den beiden Armen 166, 167 der Stützfeder 163 vergrössert wird. Auf diese Art wird mittels der Mittelzonenverstärkung in einer mittleren Zone des Lattenrosts eine stufenlose Regulierung der elastischen Federkraft des Lattenrosts gewährleistet.The connecting part between the two arms 166, 167 of the support spring 163 is below the cover part 175 and the adjusting screw 165 passed through, the curvature this connection part is dimensioned such that the support spring 163 between the leads both support surfaces 176, 177 under the adjusting screw 165, but does not reach down to the bottom of the aluminum hollow profile 153. By means of the Set screw 165 can now the connecting part of the support spring 163 with respect to Aluminum profile 153, on which the support spring 163 is mounted, optionally loaded from above and pushed down or relieved. If the set screw 165 after screwed below and thereby the connecting part of the support spring 163 down to Bottom of the aluminum profile 153 is pressed, the radius of curvature Connection portion between the two arms 166, 167 of the support spring 163 reduced. As a result, the outer ends of the two arms 166, 167 of the support spring 163 raised or pushed upwards, so that at these outer ends attached support elements 181, 182 a greater support force on the above them Exercise arranged battens 171, 172. The supporting force of the supporting elements is reversed 181, 182 on the slats 171, 172 reduced when the set screw 165 is up screwed and thereby the radius of curvature of the connecting part between the both arms 166, 167 of the support spring 163 is enlarged. In this way, the Middle zone reinforcement in a middle zone of the slatted frame a stepless Regulation of the elastic spring force of the slatted frame guaranteed.

Zusammenfassend ist festzustellen, dass durch die Erfindung ein Lattenrost für Liegemöbel geschaffen wird, der einerseits eine geringe Bauhöhe aufweist und somit zum Einlegen in ein Gestell eines Liegemöbels geeignet ist, und der andrerseits einen grossen Federweg für die Latten bereitstellt, insbesondere auch im Bereich der die Latten tragenden Längsträger.In summary, it can be stated that the invention provides a slatted frame for reclining furniture is created, which on the one hand has a low overall height and thus for insertion in a frame of reclining furniture, and on the other hand a large one Provides travel for the slats, especially in the area of the slats carrying Side members.
