Abstract

A frame made of cross and longitudinal members with spring elements that are easy to mount and having a progressive effect for plate-like supports (5) for example, upon which the mattress or seat upholstery rests. Each spring element is comprised of an approximately C-shaped lower leaf-spring (3) placed in a horizontal position and a substantially mirror-symmetrical upper leaf-spring (4) which ends are connected to the ends of the lower leaf-spring (3). By fitting a double wedge (7a, 7b) at least in between the lower leaf-spring (3) and the part of the frame supporting it (1) the progressive effect can be modified to a substantial extent.

Description

Die Erfindung betrifft einen Rahmen aus Längs- und Querholmen und mit auf Federelementen sitzenden Unterstützungen für die Matratze oder das Sitzpolster eines Liege- oder Sitzmöbels.The invention relates to a frame made of longitudinal and transverse bars and with supports on spring elements for the mattress or the seat cushion of a couch or seating furniture.

Aus der DE 35 08 757 A1 ist ein Rahmen in Form eines Lattenrostes bekannt, bei dem die Unterstützungen der Matratze aus elastischen Querlatten bestehen, von denen jede sich an ihren beiden Enden an den sich gegenüberliegenden Längsholmen des Rahmens über je eine Ω-förmig gebogene, progressiv wirkende Feder abstützt, deren Scheitel mit der Querlatte verbunden ist, und deren untere Schenkelenden mit dem betreffenden Holm verschraubt sind. Zur Begrenzung der Durchfederung sind jeder Ω-Feder elastische Anschläge zugeordnet.DE 35 08 757 A1 describes a frame in the form of a slatted frame known in which the supports of the mattress elastic crossbars exist, each of which is attached their two ends on the opposite longitudinal spars the frame over a Ω-shaped, progressive acting spring supports, the apex with the crossbar is connected, and the lower leg ends with the relevant spar are screwed. To limit the Elastic stops are assigned to each Ω spring.

Aus der CH 680 337 A5 ist ein Rahmen in Form eines Lattenrostes bekannt, bei dem die Unterstützungen der Matratze nicht aus elastischen Querlatten sondern aus zahlreichen, gleichmäßig verteilt angeordneten Tellern bestehen, von denen jeder auf einer komplizierten Feder- und Anschlagkonstruktion sitzt, die starre U-Profil-Querträger umfaßt. Zwar bietet dieser Lattenrost wegen der näherungsweise punktuellen Unterstützung der Matratze durch die beschriebenen Federelemente einen erhöhten Liegekomfort, ist aber konstruktiv und montagetechnisch äußerst aufwendig.From CH 680 337 A5 is a frame in the form of a slatted frame known where the supports of the mattress not from elastic crossbars but from numerous, consist evenly arranged plates of each one on a complicated spring and stop construction sits, which includes rigid U-profile cross members. This slatted frame offers approximately because of the selective support of the mattress by the described Spring elements increased comfort, but is extremely complex in terms of construction and assembly technology.

Der Erfindung liegt die Aufgabe zugrunde, einen Rahmen der einleitend angegebenen Gattung mit konstruktiv einfachen, leicht zu montierenden, progressiv wirkenden Federelementen zu schaffen.The invention has for its object a framework initially specified type with structurally simple, easy to install, progressive spring elements to accomplish.

Erfindungsgemäß ist diese Aufgabe gelöst, wie im Anspruch 1 angegeben. Jedes Federelement besteht also aus zwei C-förmigen, einander zugewandten Blattfedern, die an ihren Enden miteinander verbunden sind. Die untere und die obere Blattfeder können unterschiedliche Materialstärken haben oder aus Werkstoffen unterschiedlicher Elastizität bestehen, sodass sich die Federhärte des zusammengesetzten Federelementes durch Kombination unterschiedlicher Blattfedern ohne nennenswerten Aufwand variieren läßt. Solche Federelemente sind preiswert z.B. aus rostfreiem Stahl herstellbar. Sie sind des weiteren leicht zu montieren, denn hierzu genügt eine Schraube oder ein gleichwertiges Befestigungsmittel, das die untere Blattfeder auf dem sie tragenden Teil des Rahmens festlegt und eine weitere Schraube zur Verbindung der oberen Blattfeder mit der Unterseite des Unterstützungsmittels, auf dem die Matratze liegt. Die C-Form sorgt für den gewünschten, progressiven Verlauf der Federcharakteristik. Gleichzeitig ist dieses Federelement überlastungssicher. Anschläge zur Federwegbegrenzung sind deshalb nicht notwendig. Ebenso sind keinerlei zusätzliche Führungen erforderlich sondern alle Federelemente sind freistehend montiert.According to the invention, this object is achieved, as in claim 1 specified. Each spring element consists of two C-shaped leaf springs facing each other at their ends are interconnected. The lower and the upper leaf spring can have different material thicknesses or from Materials of different elasticity exist so that the spring hardness of the composite spring element by combining different leaf springs without any noteworthy Effort can vary. Such spring elements are inexpensive e.g. Can be made from stainless steel. they are easy to assemble, because one is sufficient Screw or equivalent fastener that the lower leaf spring on the part of the frame that supports it sets and another screw to connect the upper leaf spring with the bottom of the support means, on which the mattress lies. The C shape ensures the desired, progressive course of the spring characteristic. At the same time, this spring element is overload-proof. Stops to limit travel are therefore not necessary. There are also no additional tours required but all spring elements are free-standing assembled.

Zur Verbindung der Enden der unteren Blattfeder mit denjenigen der oberen Blattfeder kommen alle geeigneten, dem Fachmann bekannten Verbindungstechniken in Betracht. Besonders vorteilhaft ist es, wenn gemäß Anspruch 2 die Enden der unteren Blattfeder diejenigen der oberen Blattfeder formschlüssig umgreifen, was durch eine entsprechende Profilgebung schon bei der Herstellung der Blattfedern berücksichtigt werden kann, so daß gesonderte Arbeitsgänge wie Verschweißen, Anbringen von Bohrungen, Splinten und dergleichen entbehrlich sind. Gewünschtenfalls können zwischen die sich umgreifenden Enden der unteren und der oberen Blattfeder Gleitmittel, z.B. auch in Form von PTFE-Folien angeordnet werden. Dem Verwendungszweck der Federelemente entsprechend, kommt es im Ergebnis nur darauf an, daß die Blattfedern an ihren Enden zuverlässig miteinander verbunden sind, jedoch beim Ein- und Ausfedern keine durch Reibung Verursachten Geräusche entstehen.To connect the ends of the lower leaf spring to those The top leaf spring comes with all suitable, the specialist known connection techniques into consideration. Especially It is advantageous if, according to claim 2, the ends of the lower leaf spring those of the upper leaf spring form-fitting embrace what through appropriate profiling already taken into account in the manufacture of the leaf springs can be, so that separate operations such Welding, drilling holes, split pins and the like are unnecessary. If desired, you can choose between the gripping ends of the lower and upper Leaf spring lubricant, e.g. also in the form of PTFE films to be ordered. The intended use of the spring elements accordingly, the only important thing in the result is that the Leaf springs are reliably connected at their ends are, but not due to friction during compression and rebound Noises are created.

Sofern die Breite des die Federelemente tragenden Teils des Rahmens die Breite der Blattfedern nicht wesentlich übersteigt, läßt sich die Progressionswirkung der Federelemente sehr einfach auf einen niedrigeren Wert einstellen, wenn gemäß Anspruch 3 jedes Federelement um 90° um seine Hochachse drehbar ist. In der gegenüber der Längsachse des tragenden Teils des Rahmens um ca. 90° gedrehten Stellung ist nämlich die Unterstützungsfläche der unteren Blattfeder entsprechend schmaler, was einer verringerten Progressionswirkung entspricht.If the width of the part of the spring elements carrying Frame does not significantly exceed the width of the leaf springs, the progression effect of the spring elements very easily set to a lower value if according to claim 3, each spring element by 90 ° about its vertical axis is rotatable. In the opposite of the longitudinal axis of the load-bearing part of the frame rotated by about 90 ° is namely the support surface of the lower leaf spring correspondingly narrower, which means a reduced progression effect corresponds.

Umgekehrt kann eine Erhöhung der Progressionswirkung sehr einfach dadurch erzielt werden, daß gemäß Anspruch 4 zwischen der unteren Blattfeder und dem diese tragenden Teil des Rahmens ein unterer Doppelkeil angeordnet wird. Dieser Doppelkeil, beispielsweise aus Holz oder Kunststoff, hat von der Mitte zu seinen Enden hin ansteigende Keilflächen und kann auch so ausgebildet sein, daß er sich nachträglich zwischen den tragenden Teil des Rahmens und die untere Blattfeder einschieben läßt. Unterschiedlich starke Doppelkeile ermöglichen es, ein nahezu beliebiges Progressionsverhalten einzustellen.Conversely, an increase in the progression effect can be very can be easily achieved in that according to claim 4 between the lower leaf spring and the part supporting it a lower double wedge is arranged on the frame. This Double wedge, for example made of wood or plastic, has from wedge surfaces rising in the middle towards its ends and can also be designed so that it can be added later between the supporting part of the frame and the lower one Leaves leaf spring inserted. Double wedges of different strengths allow almost any progression behavior adjust.

Das gleiche läßt sich gemäß Anspruch 5 alternativ oder zusätzlich durch einen oberen Doppelkeil erreichen, der zwischen der oberen Blattfeder und der Unterstützung der Matratze oder des Sitzpolsters angeordnet wird. The same can alternatively or additionally according to claim 5 reach through an upper double wedge between the top leaf spring and the support of the mattress or the seat cushion is arranged.

Wenn die Doppelkeile gemäß Anspruch 6 um 90° um die Hochachse des Federelementes drehbar sind, läßt sich die durch die Doppelkeile erzielte, erhöhte Progressionswirkung stufenweise verringern. Die geringste Progressionswirkung wird dann erhalten, wenn die Doppelkeile in ihrer normalen Einbaulage verbleiben, das Federelement jedoch gemäß Anspruch 3 aus seiner normalen Einbaulage um 90° um seine Hochachse gedreht wird. Alle vorgenannten Einstellungen lassen sich werkzeuglos vom Benutzer durchführen. Der Benutzer kann daher das Federungsverhalten seines Liege- oder Sitzmöbels in weiten Grenzen, vor allem auch bereichsweise unterschiedlich, nach seinen Wünschen gestalten.If the double wedges according to claim 6 by 90 ° about the vertical axis of the spring element are rotatable, can by the double wedges gradually achieved increased progression effect reduce. The least progression effect is then obtained when the double wedges are in their normal installation position remain, but the spring element according to claim 3 from its normal installation position by 90 ° around its vertical axis is rotated. All of the above settings can be made Carry out by the user without tools. The user can hence the suspension behavior of his reclining or seating furniture within wide limits, especially different in certain areas, design according to his wishes.

Gemäß Anspruch 7 kann der die Federelemente tragende Teil des Rahmens aus dessen Längsholmen bestehen, in welchem Fall die auf den Federelementen sitzenden Unterstützungen der Matratze aus den üblichen, gewöhnlich elastischen Querlatten bestehen.According to claim 7, the part carrying the spring elements of the frame from its longitudinal spars, in which case the supports of the Mattress made from the usual, usually elastic crossbars consist.

Bei einer besonders komfortablen, im Anspruch 8 angegebenen Ausführungsform des Rahmens sind stattdessen die Federelemente auf Querlatten angeordnet und die auf den Federelementen sitzenden Unterstützungen der Matratze bestehen aus Stütztellern.With a particularly comfortable, specified in claim 8 The embodiment of the frame are instead the spring elements arranged on crossbars and those on the spring elements seated supports of the mattress consist of Support plates.

Rahmen aus Längs- und Querholmen für Liege- oder Sitzmöbel sind allgemein bekannt und daher in der Zeichnung nicht dargestellt. Die Zeichnung zeigt vielmehr lediglich die für das Verständnis der Erfindung notwendigen Teile.Frame made of longitudinal and cross bars for reclining or seating are generally known and therefore not in the drawing shown. Rather, the drawing shows only those for understanding the necessary parts of the invention.

In Figur 1 ist schematisch eine Querlatte 1 wiedergegeben, auf der mittels einer angedeuteten Schraube 2 eine untere, näherungsweise C-förmige, liegend angeordnete Blattfeder 3 befestigt ist, die mit ihren Enden 31 die Enden 41 einer ansonsten im wesentlichen spiegelsymmetrischen, oberen Blattfeder 4 formschlüssig umgreift. Die obere Blattfeder 4 trägt einen Stützteller 5. Statt dieses Stütztellers könnte die obere Blattfeder 4 auch eine übliche Querlatte eines Bettrahmens oder dergleichen tragen, in welchem Fall die untere Blattfeder 3 statt auf der Querlatte 1 auf einem Längsholm des Rahmens befestigt wäre.In Figure 1, a crossbar 1 is shown schematically, on which, by means of an indicated screw 2, a lower, approximately C-shaped leaf spring 3 arranged horizontally is attached, the ends 41 of the ends 41 one otherwise essentially mirror-symmetrical, upper Leaf spring 4 engages positively. The upper leaf spring 4 carries a support plate 5. Instead of this support plate could the upper leaf spring 4 also a usual crossbar Wear bed frame or the like, in which case the lower leaf spring 3 instead of on the crossbar 1 on a Longitudinal spar of the frame would be attached.

Figur 2 zeigt, daß die untere Schraube 2 mit einer Kunststoffkappe 2.1 abgedeckt ist, die gewünschtenfalls auch die Funktion eines Puffers übernehmen kann. Die obere Blattfeder 4 ist in entsprechender Weise über eine Schraube 6 mit einer Kunststoffkappe 6.1 mit dem Teller 5 verbunden. Die Lage des Federelementes 3, 4 und des Tellers 5 bei Belastung in Richtung des Pfeiles ist gestrichelt angedeutet.Figure 2 shows that the lower screw 2 with a plastic cap 2.1 is covered, if desired also Can take over the function of a buffer. The top leaf spring 4 is in a corresponding manner via a screw 6 with a Plastic cap 6.1 connected to the plate 5. The location of the Spring element 3, 4 and the plate 5 when loaded in the direction the arrow is indicated by dashed lines.

Die durch die Form der unteren Blattfeder 3 bedingte Progressionswirkung beim Einfedern läßt sich durch Verringerung der Breite der Unterstützungsfläche der unteren Blattfeder verkleinern. Am einfachsten geschieht dies durch Verdrehung des Federelementes 3, 4 um 90° in die in Figur 3 gezeigt Stellung.The progression effect caused by the shape of the lower leaf spring 3 compression can be reduced the width of the support surface of the lower leaf spring downsize. The easiest way to do this is by twisting of the spring element 3, 4 by 90 ° in that shown in Figure 3 Position.

Umgekehrt läßt sich die Progressionswirkung erhöhen, in dem man die Unterstützungfläche der unteren Blattfeder 3 vergrößert, uzw. wie in Figur 4 dargestellt, durch Anordnung eines Doppelkeils 7a, 7b zwischen der Latte 1 und der unteren Blattfeder 3. Der Doppelkeil kann insbesondere so ausgebildet sein, daß er sich auch nachträglich einsetzen, insbesondere von der Seite her einschieben läßt. Hierzu können die beiden Keile 7a, 7b in der Mitte über einen dünnen Steg verbunden sein, der ein zentrales Loch oder eine U-förmige, zu einer Schmalseite offene Ausnehmung hat (nicht dargestellt). Zum nachträglichen Einsetzen des Doppelkeiles 7a, 7b wird im einfachsten Fall die Schraube 2 wieder herausgedreht oder einige Gewindegänge gelöst. Eine andere Möglichkeit besteht darin, die untere Blattfeder 3 so auf der Latte 1 zu montieren, daß ein kleiner, für das seitliche Einschieben des Doppelkeiles 7a, 7b ausreichender Spalt verbleibt.Conversely, the progression effect can be increased in the the support surface of the lower leaf spring 3 is increased, etc. as shown in Figure 4, by arrangement a double wedge 7a, 7b between the crossbar 1 and the lower one Leaf spring 3. The double wedge can be designed in particular be that he can also use it later, in particular can be inserted from the side. You can do this the two wedges 7a, 7b in the middle over a thin web connected to a central hole or a U-shaped has a recess open to a narrow side (not shown). For the subsequent insertion of the double wedge 7a, 7b, in the simplest case, screw 2 is unscrewed again or loosened a few threads. Another possibility is the lower leaf spring 3 so on the crossbar 1 to mount that a small one, for side insertion of the double wedge 7a, 7b sufficient gap remains.

Der Doppelkeil 7a, 7b kann jedoch von vornherein mitmontiert, in diesem Fall z.B. auch auf die Latte 1 aufgeklebt sein, denn gemäß Figur 5 läßt sich die Wirkung des Doppelkeils 7a, 7b durch Verdrehen des Federelementes 3, 4 um 90° ausschalten.The double wedge 7a, 7b can, however, also be assembled from the outset, in this case e.g. also glued to the crossbar 1 be, because according to Figure 5, the effect of the double wedge 7a, 7b by turning the spring element 3, 4 by 90 ° turn off.

Gemäß Figur 6 kann zur weiteren Erhöhung der Progressionswirkung auch zwischen der oberen Blattfeder 4 und dem Tellerelement 5 ein (weiterer) Doppelkeil 8a, 8b angeordnet werden.According to FIG. 6, the progression effect can be increased further also between the upper leaf spring 4 and the plate element 5 a (further) double wedge 8a, 8b arranged become.

Wenn die auf diese Weise geschaffenen Möglichkeiten zur Veränderung der Progressionswirkung des Federelementes nicht ausreichen, können schließlich auch die Doppelkeile 7a, 7b und 8a, 8b ihrerseits um 90° um die Hochachse drehbar montiert werden (nicht dargestellt).If the possibilities created in this way for No change in the progression effect of the spring element sufficient, the double wedges 7a, 7b can finally and 8a, 8b, in turn, mounted rotatable through 90 ° about the vertical axis (not shown).
