Abstract

The main bridge (6) supporting the load has one or more supporting members (8) more flexible or elastic than it. These members are flat, and protrude from the bridge in the sideways direction, parts of them extending upwards beyond the bridge surface. The members can bend downwards under load, the area nearest the bridge bending at the most through no greater an angle than one further away. Each member can form a wing-type lip sloping upwards. Alternatively, it can be divided into several segments. There can be a flat horizontal supporting member along its outer edge.

Description

Die vorliegende Erfindung betrifft eine Federbrücke für eine als Federbrückenrost ausgebildete Untermatratze, wie sie im Oberbegriff des unabhängigen Patentanspruchs 1 definiert ist.The present invention relates to a spring bridge for a mattress designed as a spring bridge grate, such as it is defined in the preamble of independent claim 1 is.

Federbrückenroste werden in vielfältigen Ausführungen als Unterfederung für eine Polsterauflage, beispielsweise ein Sitzkissen oder eine Matratze, verwendet. Dabei hat sich, insbesondere für Betten mit hohem und gesundheitlich optimalem Liegekomfort, die flexible Lagerung der Federbrücken sehr bewährt.Spring bridge gratings are available in various designs Spring base for a cushion cover, for example a Seat cushion or a mattress. In doing so, especially for beds with high and optimal health Lying comfort, the flexible suspension of the spring bridges very proven.

Die Flexibilität dieser Federbrücken wird nach Stand der Technik durch elastische Aufhängung der einzelnen Federleisten am Rahmen erreicht und es sind zu diesem Zweck verschiedene Varianten von speziellen elastischen Stützkörpern für die Federleisten bekannt geworden, wie sie unter anderem in den deutschen Patentschriften DE-PS 25 36 898 und DE-PS 28 42 038 beschrieben sind.The flexibility of these spring bridges is according to the Technology through elastic suspension of the individual female connectors reached on the frame and there are for this purpose different variants of special elastic support bodies become known for the female connectors, as under other in the German patents DE-PS 25 36 898 and DE-PS 28 42 038 are described.

Aus dem deutschen Gebrauchsmusters DE-G 93 17114 ist eine andere Art von Federbrücken bekannt, bei denen sich die Flexibilität durch das Anordnen mehrerer Federelemente auf einer Haupttragbrücke ergibt.From the German utility model DE-G 93 17114 is one known other type of spring bridges, in which the Flexibility by arranging multiple spring elements a main girder bridge.

Mit den genannten Federbrücken lassen sich Federbrückenroste konstruieren, die sich - im Zusammenspiel mit der Matratze - optimal auf einen liegenden Körper einstellen, der ja aufgrund seiner Beschaffenheit und Liegestellung lokal mit sehr unterschiedlicher und immer wieder veränderter Auflagekraft aufliegt.Spring bridge gratings can be made with the spring bridges mentioned construct, which - in interaction with the Mattress - optimally adjust to a lying body, because of its nature and lying position locally with very different and constantly changing Tracking force.

Diesen überzeugenden Vorteilen der bisher bekannt gewordenen Konstruktionen in bezug auf den Liegekomfort stehen jedoch gewisse Nachteile hinsichtlich der Fertigungskosten gegenüber. So sind insbesondere die bei diesen Arten von Federbrückenrosten benötigten elastischen Stützkörper bzw. Federelemente, meist aus Gummi gefertigt und von relativ kompliziertem Aufbau, kostenintensive Zusatzteile.These convincing advantages of the previously known Constructions related to lying comfort however, certain disadvantages in terms of manufacturing costs across from. So in particular those with these types of Spring bridge gratings require elastic support bodies or Spring elements, mostly made of rubber and of relative complicated structure, costly additional parts.

Aus der DE-B-27 03 199 ist eine Federbrücke bekannt, die im Bereich Ihrer Enden eben ist, zu Ihrer Mitte hin jedoch zunehmend stärker muldenförmig verläuft. Aufgrund dieser Ausbildung erhält die Federleiste in ihrem das grösste Biegemoment aufnehmenden mittleren Bereich ein entsprechend hohes Widerstandsmoment, während dieses Widerstandsmoment in Übereinstimmung mit den zu den Enden der Federleiste abnehmenden Biegemomenten entsprechend abnimmt. Diese Federleiste hat aber den Nachteil, dass sie keine für einen hohen Liegekomfort notwendigen, sich lokal progressiv anpassenden Federeigenschaften aufweist.From DE-B-27 03 199 a spring bridge is known which in Area of your ends is flat, but increasing towards your middle runs more trough-shaped. Because of this training the female connector receives the greatest bending moment in it receiving middle area a correspondingly high Section modulus, during this section modulus in According to those decreasing towards the ends of the female connector Bending moments decreases accordingly. This female connector but has the disadvantage that they are not for a high Lying comfort necessary, adapting locally progressively Has spring properties.

Es ist daher die Hauptaufgabe der vorliegenden Erfindung, einen Federbrückenaufbau vorzuschlagen, der einerseits eine kostengünstige Herstellung eines Federbrückenrostes ermöglicht, andererseits trotzdem die für einen hohen Liegekomfort notwendigen Funktionen, insbesondere sich lokal progressiv anpassende Federeigenschaften, aufweist.It is therefore the main object of the present invention propose a spring bridge structure that on the one hand enables inexpensive manufacture of a spring bridge grate, on the other hand, nevertheless, for a high lying comfort necessary functions, especially locally progressive adapting spring properties.

Die erfindungsgemässe Federbrücke ist im unabhängigen Patentanspruch 1 definiert; bevorzugte Ausführungsformen ergeben sich aus den abhängigen Patentansprüchen. The spring bridge according to the invention is in the independent claim 1 defined; preferred embodiments result itself from the dependent claims.

Demgemäss umfasst die Federbrücke eine Haupttragbrücke und mindestens ein an dieser angeordnetes, flächig ausgebildetes, flexibles Abstützelement. Die Haupttragbrücke kann an den Seitenteilen einer Untermatratze montiert werden und nimmt somit letztlich die Traglast auf. Das Abstützelement erstreckt sich in seitlicher Richtung quer zur Längsachse der Haupttragbrücke und, zumindest mit Teilpartien, über die Oberseite der Haupttragbrücke nach oben. Es ist so ausgebildet, dass es flexibler und/oder elastischer ist als die Haupttragbrücke selbst. Accordingly, the spring bridge comprises a main support bridge and at least one flat, arranged on this, flexible support element. The main bridge can be mounted on the side parts of a base mattress and ultimately takes the load. The support element extends laterally across the longitudinal axis the main bridge and, at least with parts, over the top of the main girder bridge up. It is designed that it is more flexible and / or elastic than the main support bridge itself.

Vorzugsweise ist das Abstützelement so ausgebildet, dass es bei Belastung durch eine Auflagekraft (normalerweise dem lokal wirkenden Gewicht einer aufgelegten Matratze und einer darauf ruhenden Person) nach unten gebogen wird, wobei ein näher bei der Haupttragbrücke liegender Bereich um einen höchstens gleich grossen Winkel wie ein weiter entfernter Bereich gedreht wird.The support element is preferably designed such that it when loaded by a contact force (usually the locally acting weight of a mattress and a person resting on it) is bent down, whereby an area around the main support bridge an angle of at most the same size as a further one Area is rotated.

In einer bevorzugten Ausführungsform hat das Abstützelement die Form einer flügelartigen, sich von der Haupttragbrücke nach schräg aufwärts erstreckenden Lippe. Zweckmässig ist auf beiden Längsseiten der Haupttragbrücke je wenigstens ein Abstützelement angeordnet.In a preferred embodiment, the support element the shape of a wing-like, extending from the main support bridge towards the lip, which extends obliquely upwards. Is appropriate at least on both long sides of the main support bridge a support element is arranged.

Da die Flexibilität des Abstützelementes weicher ist als diejenige der Haupttragbrücke, verformt es sich schon unter leichter Last, während die Haupttragbrücke erst bei grösserer Last nachgibt. Mit anderen Worten ergeben sich unterschiedliche, sich addierende Tragkräfte, und damit sich progressiv anpassende Federeigenschaften.Since the flexibility of the support element is softer than that of the main support bridge, it already deforms under light load, while the main girder bridge only with larger Load gives way. In other words, there are different accumulating load capacities, and thus themselves progressively adapting spring properties.

Auf diese Weise wird eine lokale Elastizität bzw. Federwirkung und in gewisser Hinsicht auch Gelenkigkeit der Federbrücke erreicht, und zwar ohne eine spezielle, flexible Aufhängung. Erfindungsgemäss ausgebildete Federbrücken weisen so die für ein komfortables Liegen notwendigen Federeigenschaften und Nachgiebigkeit quer zur Längsachse der Federbrücke in sich selbst auf.In this way there is a local elasticity or spring action and in a way also flexibility of the spring bridge achieved, without a special, flexible Suspension. Spring bridges designed according to the invention so the spring properties necessary for comfortable lying and compliance transverse to the longitudinal axis of the Spring bridge in itself.

Die Flexibilität bzw. Elastizität des Abstützelementes bezüglich der Haupttragbrücke lässt sich durch passende Wahl von Material und Querschnittsabmessungen geeignet einstellen. Wie Versuche gezeigt haben, ist es in der Regel für eine Untermatratze eines Betts für eine Person mit Normalgewicht passend, wenn sich das Abstützelement mit einer lokalen Auflagekraft von etwa 20 Newton (2 Kilopond) bis auf die Ebene der Oberseite der Haupttragbrücke niederdrücken lässt.The flexibility or elasticity of the support element with respect the main girder bridge can be selected of material and cross-sectional dimensions. As experiments have shown, it is usually for a bed under mattress for a normal weight person suitable if the support element with a local contact force of about 20 Newtons (2 Kilopond) to to the level of the top of the main girder bridge leaves.

Bei besonderen Ausführungsformen kann das Abstützelement in Längsrichtung der Federbrücke in mehrere Segmente aufgeteilt sein oder es können mehrere Abstützelemente segmentweise angeordnet sein, wodurch die lokal unterschiedlich anpassbare Federwirkung noch verbessert wird.In special embodiments, the support element in Longitudinal direction of the spring bridge divided into several segments or there can be several support elements in segments be arranged, which makes the locally different adjustable spring action is still improved.

Bevorzugte Ausführungsformen der Abstützelemente und der Haupttragbrücke sind so ausgebildet, dass sie ohne Werkzeuge montierbar sind und sich für die Selbstmontage eignen.Preferred embodiments of the support elements and the Main support bridge are designed so that they are without tools can be assembled and are suitable for self-assembly.

Ein weiterer Vorteil erfindungsgemässer Federbrücken betrifft die Belüftung einer darauf liegenden Obermatratze. Dank der sich über die Oberseite der Haupttragbrücke nach oben erstreckenden Abstützelemente liegt die Obermatratze zumindest in unbelastetem oder nur partiell belastetem Zustand nicht vollständig auf den Federbrücken auf, sondern es ergibt sich ein Zwischenraum, durch den die Unterseite der Obermatratze auch im Bereich der Federbrücken belüftet und die Verdunstung der in der Obermatratze entstehenden Feuchtigkeit erleichtert wird. Zudem bewirken Verlagerungen einer auf der Matratze ruhenden Person in den Zwischenräumen einen Pumpeffekt, der die Belüftung noch verbessert. Weil so die Belüftungsproblematik, welche bei flach an der Matratze anliegenden Federleisten deren Breite auf ein bestimmtes Höchstmass beschränkt, gelöst ist, können zudem die Federbrücken breiter sein, so dass eine kleinere Anzahl zur Bildung eines Rosts ausreicht. Another advantage of spring bridges according to the invention relates the ventilation of an upper mattress lying on it. Thanks to the over the top of the main support bridge The top mattress extends above the support elements at least in the unloaded or only partially loaded state not completely on the spring bridges, but there is a space through which the bottom the top mattress is also ventilated in the area of the spring bridges and the evaporation of those arising in the top mattress Moisture is relieved. In addition, relocations cause a person resting on the mattress in the gaps a pumping effect that improves ventilation. Because so the ventilation problem, which with flat on the Mattress adjoining slats whose width is limited to a certain one Restricted as much as possible, can also the spring bridges be wider so that a smaller number sufficient to form a rust.

Die genannten Vorteile werden durch die erfindungsgemässe Ausbildung einer Federbrücke in äusserst kostengünstiger Weise erreicht. Es entfallen sowohl teure Stützkörper für die Aufhängung der Federbrücken als auch besondere Einrichtungen zur unterseitigen Belüftung der Obermatratze. Ferner bedeutet der ermöglichte Verzicht auf spezielle Stützkörper eine wesentliche Vereinfachung bei der Montage eines Federbrückenrostes.The advantages mentioned are due to the inventive Formation of a spring bridge in extremely inexpensive Way achieved. Both expensive support bodies are eliminated the suspension of the spring bridges as well as special facilities for underside ventilation of the top mattress. Furthermore, the possibility of doing without special means Support body a significant simplification during assembly of a spring bridge grate.

Zweckmässig und bevorzugt sind Haupttragbrücke und Abstützelement aus Kunststoff gefertigt, entweder einteilig oder als getrennte Teile. Einteilige Ausführungen ersparen zusätzliche Befestigungseinrichtungen und Montageschritte. Andererseits ergibt sich bei getrennten Teilen die Möglichkeit, verschiedene Materialien zu verwenden, zum Beispiel Werkstoffe mit unterschiedlicher Elastizität oder etwa einen glasfaserverstärkten Kunststoff für die Haupttragbrücke. Ausserdem gewährleisten getrennte Teile eine einfache Stofftrennung bei einer späteren Entsorgung.Main support bridge and support element are expedient and preferred made of plastic, either in one piece or as separate parts. One-piece designs save additional Fastening devices and assembly steps. On the other hand, with separate parts, there is the possibility to use different materials, for example Materials with different elasticity or about a glass fiber reinforced plastic for the main support bridge. In addition, separate parts ensure easy Separation of materials for later disposal.

An einer Haupttragbrücke können auch mehrere getrennte Abstützelemente vorgesehen sein. Dies erlaubt vorteilhaft, die Abstützelemente variabel anzuordnen, beispielsweise bei Federbrücken in den Bereichen grösserer Belastung (etwa im Gesässabschnitt) mehr als in den Bereichen kleinerer Belastung.Several separate support elements can also be attached to a main support bridge be provided. This advantageously allows arrange the support elements variably, for example at Spring bridges in the areas of higher loads (e.g. in Buttocks section) more than in the areas of smaller loads.

Die in den Figuren 1 bis 3 dargestellte Federbrücke, gesamthaft mit 2 bezeichnet, zeigt die grundsätzlichen Elemente der Erfindung. Gemäss Figur 1 sind eine Anzahl Federbrücken 2 zur Bildung einer Untermatratze in einem Rahmen, hier bestehend aus zwei Längszargen 4, montiert.The spring bridge shown in Figures 1 to 3, overall labeled with 2 shows the basic elements the invention. According to Figure 1 are a number of spring bridges 2 to form a sub mattress in one Frame, here consisting of two longitudinal frames 4, mounted.

Jede Federbrücke 2 besteht aus einer Haupttragbrücke 6, die als Hohlprofilstab mit im wesentlichen rechteckigem Querschnitt ausgebildet ist, und zwei je an einer Längsseite der Haupttragbrücke 6 angeordneten Abstützelementen 8. Die Abstützelemente 8 sind an der Haupttragbrücke 6 angeformt und erstrecken sich in Form einer flächigen, flügelartigen Lippe von der Haupttragbrücke in seitlicher Richtung quer zur deren Längsachse schräg nach oben und ragen mit Ausnahme ihrer direkt an die Haupttragbrücke 6 anschliessenden Partie über die Oberseite der Haupttragbrücke hinaus. Each spring bridge 2 consists of a main support bridge 6, the as a hollow profile bar with an essentially rectangular cross section is formed, and two each on one long side the main support bridge 6 arranged support elements 8. Die Support elements 8 are integrally formed on the main support bridge 6 and extend in the form of a flat, wing-like Lips laterally from the main support bridge to the longitudinal axis obliquely upwards and protrude with exception their directly adjoining the main support bridge 6 Batch beyond the top of the main girder bridge.

Aufgrund ihrer flächigen Ausbildung und geringen Dicke besitzen die Abstützelemente 8 bezüglich der Haupttragbrücke 6 eine vergleichsweise grosse Flexibilität bzw. Elastizität, die in jedem Fall weicher ist als die Flexibilität bzw. Elastizität des Hohlprofils der Haupttragbrücke. Daher werden unter der Wirkung einer kleinen Auflagekraft hauptsächlich die Abstützelemente 8 gebogen und bis auf die Ebene der Oberseite der Haupttragbrücke und gegebenenfalls auch weiter nach unten niedergedrückt, wie dies durch die verschiedenen Stellungen entlang der Pfeile A in Figur 3 angedeutet ist, während die Haupttragbrücke 6 nur leicht nachgibt (Pfeil B). Erst wenn die Auflagekraft grösser ist und nach Niederdrücken der Abstützelemente 8 zudem direkt auf die Haupttragbrücke 6 wirken kann, wird auch letztere stärker verformt.Owing to their flat design and small thickness the support elements 8 with respect to the main support bridge 6 a comparatively great flexibility or Elasticity that is softer than flexibility in any case or elasticity of the hollow profile of the main support bridge. Therefore, under the effect of a small tracking force mainly the support elements 8 bent and except for the Level the top of the main support bridge and if necessary also depressed further down, like this by the different positions along the arrows A in FIG. 3 is indicated, while the main support bridge 6 only slightly gives way (arrow B). Only when the tracking force is greater and after pressing down the support elements 8 also directly can act on the main support bridge 6, the latter also deformed more.

In umgekehrter Sichtweise wirken somit in der Federbrücke 2 entgegen einer Auflagekraft unterschiedliche, sich addierende Tragkräfte; sie weist damit die gewünschten, sich progressiv anpassenden Federeigenschaften auf. Überdies lassen sich die Abstützelemente 8 in Längsrichtung der Federbrücke abschnittsweise unterschiedlich niederdrücken, so dass auch in dieser Richtung lokal unterschiedliche Belastungszustände möglich sind. Ebenso kann das Abstützelement auf der einen Seite der Haupttragbrücke weiter nach unten gedrückt sein als dasjenige auf der anderen Seite, wodurch sich eine gegenüber der Horizontalen geneigte Gesamtauflagefläche ergibt und die Federbrücke in ihrer wirksamen Lage gewissermassen gelenkig gekippt ist.In the opposite perspective, spring bridge 2 thus acts against one another, different, adding up Load capacities; it thus shows the desired ones progressively adapting spring properties. Moreover can the support elements 8 in the longitudinal direction Press the spring bridge differently in sections, so that locally different also in this direction Stress conditions are possible. Likewise, the support element continue on one side of the main support bridge pressed down than the one on the other side, whereby there is a total contact surface inclined to the horizontal results and the spring bridge in its effective Location is tilted to a certain extent.

Das Ausführungsbeispiel von Figur 4 entspricht im allgemeinen der vorgängig beschriebenen. Hier jedoch sind die beiden Abstützelemente durch Ausnehmungen 10 in Längsrichtung der Federbrücke in mehrere Segmente 12 aufgeteilt. Sie können sich daher in noch grösserem Ausmass lokal unterschiedlich anpassen.The embodiment of Figure 4 corresponds in general the previously described. But here they are two support elements through recesses 10 in the longitudinal direction the spring bridge divided into several segments 12. They can therefore be local to an even greater extent adjust differently.

Die Figuren 5 und 6 zeigen Federbrücken, bei welchen Abstützelement und Haupttragbrücke getrennte Teile sind. Bei beiden Ausführungen ist die Haupttragbrücke ein Hohlprofilstab 14, beispielsweise aus glasfaserverstärktem Kunststoff, mit einem Längsschlitz 16. Der Längsschlitz 16 und die an ihn angrenzenden Wandstege 18 bilden eine hinterschnittene Nut, in die ein am jeweiligen Abstützelement ausgebildeter Haltesteg 20 bzw. 22 einschiebbar ist. In Figur 5 sind zwei flügelartige Lippen 24 zu einem einzigen, flach V-förmigen Abstützelement vereint, während in Figur 6 mehrere flügelartige Abstützelemente 26 in Längsrichtung der Federbrücke segmentweise hintereinander angeordnet sind. Dabei können die Abstützelemente 26 in unterschiedlichen Anordnungen eingefügt sein, etwa - wie gezeigt - wechselseitig ausgerichtet oder alle auf dieselbe Seite oder auch gruppenweise auf die eine und dann wieder auf die andere Seite, beispielsweise zwei links, zwei rechts usw. Ebenso lassen sich die Abstände zwischen den Abstützelementen frei wählen, so dass eine derartige Ausführung insgesamt viele Möglichkeiten zur variablen Gestaltung der Federbrücke bietet.Figures 5 and 6 show spring bridges, in which support element and main support bridge are separate parts. At In both versions, the main support bridge is a hollow section bar 14, for example made of glass fiber reinforced plastic, with a longitudinal slot 16. The longitudinal slot 16 and the adjacent wall webs 18 form an undercut Groove into the one on the respective support element trained retaining web 20 or 22 can be inserted. In Figure 5 are two wing-like lips 24 into a single, flat V-shaped support element, while in FIG. 6 several wing-like support elements 26 in the longitudinal direction the spring bridge arranged in segments one behind the other are. The support elements 26 can be different Arrangements have been inserted, for example as shown mutually aligned or all on the same side or in groups on one and then again on the other side, for example two left, two right, etc. The distances between the support elements can also be determined choose freely so that such execution a total of many options for variable design of the Spring bridge offers.

Weitere konstruktive Varianten einer erfindungsgemässen Federbrücke zeigen die Figuren 7 bis 12. Gemäss Figur 7 ist die Haupttragbrücke als in Querrichtung mehrfach gefalteter Profilstab 28 ausgebildet, an dessen seitliche Aussenstege je ein flügelartiges Abstützelement 30 angeformt ist. Die mehrfache Faltung des Profilstabs 28 ist zweierlei Hinsicht zweckmässig. Einerseits verbessert die Mehrfachfaltung die Tragfähigkeit der Haupttragbrücke in Längsrichtung, andererseits kann die Haupttragbrücke in Querrichtung über eine auf die Abstützelemente wirkende Auflagekraft in gewissem Ausmass verformt werden und liefert so einen zusätzlichen Beitrag zu den Federeigenschaften der Abstützelemente.Further design variants of a spring bridge according to the invention show Figures 7 to 12. According to Figure 7 is the main support bridge as folded several times in the transverse direction Profile bar 28 formed, on the lateral outer webs a wing-like support element 30 is integrally formed. The Multiple folding of the profile bar 28 is two-fold expedient. On the one hand, the multiple folding improves the Load capacity of the main support bridge in the longitudinal direction, on the other hand can cross the main support bridge in the transverse direction a bearing force acting on the support elements to a certain extent Dimensionally deformed and thus provides an additional Contribution to the spring properties of the support elements.

Bei der in Figur 8 gezeigten Ausführung besteht die Haupttragbrücke aus einem massiven Stab 32 von leicht trapezförmigem Querschnitt, der mit zwei Längsbohrungen 34 versehen ist. Zwei zu einem flach V-förmigen Teil vereinte flügelartige Abstützelemente 36 sind über einen als Abstandsorgan dienenden Steg 38 auf der Oberseite der Haupttragbrücke angebracht. Diese Anordnung ermöglicht vorteilhaft eine zusätzliche Abstufung in den Federeigenschaften der Abstützelemente. Wird nämlich das über dem Stab 32 beabstandete Abstützelement 36 mit einer Auflagekraft belastet, so stösst es nach einer ersten teilweisen Durchbiegung mit seiner Unterseite auf dem Stab 32 auf. Für die weitere Durchbiegung ist somit die Biegestrecke verkürzt und damit die Flexibilität des Abstützelementes reduziert.In the embodiment shown in Figure 8 there is the main support bridge from a solid rod 32 of slightly trapezoidal Cross section provided with two longitudinal bores 34 is. Two united into a flat V-shaped part wing-like support elements 36 are via a spacer serving web 38 on the top of the main support bridge appropriate. This arrangement advantageously enables an additional gradation in the spring properties the support elements. If that is the rod 32 spaced support element 36 loaded with a contact force, so it comes after a first partial deflection with its underside on the rod 32. For the further deflection shortens the bending distance and thus reduces the flexibility of the support element.

Nach Figur 9 sind an einem als Haupttragbrücke dienenden Hohlprofilstab 40 flächig ausgebildete, leicht nach oben gebogene Abstützelemente 42 seitlich angeformt, welche an ihrer vom Hohlprofilstab 40 entfernten Längskante je ein flächiges, sich im wesentlichen horizontal erstreckendes Auflageelement 44 tragen. Zusätzlich ist die Oberseite des Hohlprofilstabs 40 durch seitlich ausladende Stege 46 verbreitert.According to FIG. 9, one serving as the main support bridge Hollow section bar 40 flat, slightly upward curved support elements 42 formed on the side, which their longitudinal edge removed from the hollow profile bar 40 each flat, essentially horizontally extending Wear support element 44. In addition, the top of the Hollow section bars 40 widened by laterally projecting webs 46.

Die in Figur 10 dargestellte Federbrücke weist als Haupttragbrücke ebenfalls einen Hohlprofilstab, hier mit 48 bezeichnet, auf. An diesem sind zwei sich je auf einer der beiden Längsseiten des Hohlprofilstabs 48 nach aussen erstreckende Lippen 50 angeformt, die an ihrer Aussenkante je ein nach oben ragendes Federelement 52 in Form eines flexiblen V-Profils tragen. Die beiden Federelemente 52 stützen ihrerseits ein flächiges Auflageelement 54. Bei dieser Ausführung ergeben sich die Federeigenschaften in vorteilhafter Weise aus dem Zusammenwirken der unterschiedlichen Elastizität des Auflageelements 54, der Federelemente 52, der Lippen 50 und des Hohlprofilstabs 48.The spring bridge shown in Figure 10 has as the main support bridge also a hollow profile rod, here designated 48, on. On this two are each on one of the two longitudinal sides of the hollow profile rod 48 extending outwards Lips 50 molded, each on its outer edge an upstanding spring element 52 in the form of a flexible Wear a V-profile. Support the two spring elements 52 in turn a flat support element 54. In this version the spring properties are more advantageous Way from the interaction of different Elasticity of the support element 54, the spring elements 52, the lips 50 and the hollow profile rod 48.

Fig. 11 weist mit Bezugsziffer 60 einen weiteren Profilstab, speziell Hohlprofilstab zur Realisierung einer Federbrücke auf. Dieser kann Vorkehrungen besitzen, die das Anbringen von Abstützelementen mittels einer Schnappverbindung (Clip) ermöglichen. Die entsprechenden Vorkehrungen können Nuten, Rillen oder Riefen sein oder, wie im gezeichneten Fall, vorstehende Kanten, Nasen 62 bzw. Federn. Ein Abstützelement oder eine Auflage 63, hier vergleichsweise grossflächig dimensioniert, ist mit einem Aufschnappprofil verbunden, welches von annähernd U-förmigem Querschnitt ist. In der gezeichneten Ausführungsform, welche als Beispiel zu verstehen ist, weist das Aufschnappprofil einen eher flachen Ummantelungsteil 64 auf. Die Elastizitätseigenschaften dieses Teils 64 sind auf diejenigen der Schnappkanten 61 abgestimmt, so dass problemloses Aufclipsen und zuverlässige Befestigung der Auflage 63 auf den Profilstab 60 möglich ist. Auflagen 63 können, wie im vorhergehenden beschrieben, frei ausladend oder aber grossflächig sein und mit mehreren Profilstäben 60 in Verbindung gebracht werden, gegebenenfalls in nur anteiliger bzw. partieller Weise. Durch die Formgebung der Belüftungsöffnungen 59 wird die erforderliche Belüftung der Obermatratze unterstützt. Gleichzeitig kann hierdurch das Elastizitätsverhalten der Auflage 63 eingestellt werden. Mittels der genannten Aufschnappverbindung können auch einzelne Auflageelemente an den Federbrücken angebracht werden.11 has a further profile bar with reference number 60, especially hollow section bar for the realization of a spring bridge on. This can have precautions to attach of support elements by means of a snap connection Enable (clip). The corresponding precautions can be grooves, grooves or grooves or, as shown in the drawing Fall, protruding edges, lugs 62 or springs. On Support element or a pad 63, here comparatively generously dimensioned, is with a snap profile connected, which has an approximately U-shaped cross section is. In the drawn embodiment, which as an example is to be understood, the snap profile has one rather flat casing part 64. The elasticity properties this part 64 are based on those of Snap edges 61 matched, so that easy clipping and reliable attachment of the pad 63 on the Profile bar 60 is possible. Pads 63 can, as in the previous described, spreading freely or over a large area be and with several profile bars 60 in connection brought, if necessary in only partial or partial Wise. Due to the shape of the ventilation openings 59 the necessary ventilation of the top mattress is supported. At the same time, the elasticity behavior the edition 63 can be set. By means of the above Single support elements can also be snapped on be attached to the spring bridges.

Wie Fig. 12 in einer Aufsicht zeigt, können kleinflächigere, ebenfalls flexible Auflageelemente 63;64;65;66;67;68 gegenseitig versetzt oder in unmittelbarer Nachbarschaft auf die Federbrücken bzw. Profilstäbe 60 aufgeclipst werden, so dass ein lokal unterschiedliches Elastizitätsverhalten der Untermatratze nach individuellen Vorgaben eingestellt werden kann. Die Wirksamkeit der beabsichtigten Entlüftungsfunktion wird dabei nicht unzulässig eingeschränkt. Die Abstützelemente können in unterschiedlichen Härtegraden gefertigt werden und sind z.B. durch entsprechende Farbgebung voneinander unterscheidbar. Eine Ausgestaltung der Oberflächen der Abstützelemente mittels Dekor, Logo oder ähnlichem ist ohne grösseren Aufwand möglich. Abstützelemente 69 sind zur Befestigung an jeweils zwei Profilstäben 60 vorgesehen und können ebenfalls wahlweise mit jeweiligem Querversatz aufgeclipst werden. Das Profil der Abstützelemente kann in vielfältigen Formen ausgestaltet sein und weist beispielsweise einen eher flächigen Querschnitt auf oder eine geschlossene Kontur, ähnlich wie in Fig. 10 gezeigt. In vergleichbarer Weise sind Abstützelemente 70 optional mit zwei oder mehreren Aufschnappprofilen an mindestens zwei, gegebenenfalls auch drei oder mehreren Profilstäben 60 aufgeclipst, je nach beabsichtigtem Elastizitätsverhalten. Die verschiedenen genannten Abstützelemente besitzen jeweils ein standardisiertes Aufschnappprofil. Durch Kombination verschiedenartiger Abstützelemente können die Flexibilitätswerte einer Untermatratze lokal variiert und in vielfältiger Weise an individuelle Wünsche angepasst werden.As shown in FIG. 12 in a top view, small-area, also flexible support elements 63; 64; 65; 66; 67; 68 mutually offset or in the immediate vicinity are clipped onto the spring bridges or profile bars 60, so that a locally different elasticity behavior the base mattress adjusted according to individual specifications can be. The effectiveness of the intended The venting function is not inadmissibly restricted. The support elements can be in different Degrees of hardness are manufactured and are e.g. by appropriate Coloring distinguishable from each other. An arrangement the surfaces of the support elements by means of decor, Logo or similar is possible without much effort. Support elements 69 are for attachment to two Profile bars 60 are provided and can also be selected be clipped on with the respective transverse offset. The profile the support elements can be designed in various forms be and has, for example, a rather flat Cross section on or a closed contour, similar to shown in Fig. 10. Support elements are comparable 70 optionally with two or more snap-on profiles on at least two, possibly also three or several profile bars 60 clipped on, depending on the intended Elasticity behavior. The various mentioned Support elements each have a standardized Snap profile. By combining different types Support elements can be the flexibility values of a Base mattress varies locally and in many ways individual wishes can be adjusted.
