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

Rahmen für Liege- oder Sitzmöbel Frame for lying or seating furniture
Die Eri j ndung betrifft einen Rahmen aus Längs- und uerhoL- iriuii und mit auf Federelementen sitzenden Un erstützungen für die Matratze oder das Sit_.polst.er eines Liege- oder S'itz- mob 1 __■ .The invention relates to a frame made of longitudinal and uerhoL iriuii and with supports on the spring elements for the mattress or the Sit_.polst.er of a reclining or sitting mob 1 __ ■.
Aus der DE 35 08 757 AI ist ej n Rahmen in Form eines Latten- rosτ;es bekannt, bei dem die Unterstützungen uer Matratze aus elastischen Querlatten bestehen, von denen jede Lc an ihren beiden Enden an den sich gegenüberliegenden Längsholmen des Rahmens über je eine Ω-formig gebogene, progressiv irkende Feder abstützt, deren Scheite] mit der Quer- atte verbunden ist, und deren untere Schenkelenden mit dem betreffenden Holm verschraubt sind. Zur Begrenzung der Durchicd runcj sind jeder Ω-Feder elastische Anschläge zugeordnet .DE 35 08 757 AI discloses a frame in the form of a slatted frame, in which the supports for the mattress consist of elastic crossbars, each of which has Lc at its two ends on the opposite longitudinal spars of the frame via one each Ω-shaped, progressively irked spring, whose logs] are connected to the crossbeam, and whose lower leg ends are screwed to the relevant spar. To limit the diameter runc j , elastic stops are assigned to each Ω spring.
Aus der C1I 680 337 A5 ist ein Rahmen in Form eines Lattenrostes bekannt, bei dem die Unterstützungen der Matratze nichr ,-ius elastischen Querlatten sondern aus zahlreichen, gleichmäßig verteilt angeordneten Tellern bestehen, von denen jeder auf einer komplizierten Feder- und Anschlag- Konstruktion sitzt, die starre U-Profil -Querträger umfaßt. Zwar bieten dieser Lattenrost wegen dei näherungsweis.' punktuei en Unterstützung der Matratze durch die beschriebenen Federelemente einen erhöhten Lj egekomr or , ist aber konstruktiv und montagetechnisch äußerst aui endig.From C1I 680 337 A5 a frame in the form of a slatted frame is known, in which the supports of the mattress do not consist of elastic crossbars but of numerous, evenly distributed plates, each of which sits on a complicated spring and stop construction , which includes rigid U-profile cross members. Although this slatted frame offer approximate. ' The support of the mattress by the spring elements described increases the lifting capacity, but is extremely finite in terms of construction and assembly technology.
Der Eπ indung l iegt di e Au fgabe zugrunde , einen Rahmen ei einleitend angegebenen Gattung mit konstruktiv einfachen, leicht zu montierenden, progressiv wirkenden Federelementen zu schaffen.The task is based on the task of creating a framework to create initially specified type with structurally simple, easy to assemble, progressively acting spring elements.
Erfindungsgemäß ist diese Aufgabe gelöst, wie im Anspruch 1 ancjegeben. Jedes Federeie ent besteht also aus zwei. C-förmigen, einander zugewandten Blattfedern, die an ihren Enden miteinander verbunden sind. Die untere und die obere Blattfeder können unterschiedliche Materialstärκen haben oder aus Werkstoffen unterschiedlicher Elastizität bestehen, sodass sich die F derhärte des zusammengesetzten Federelementes durch Komb nation unterschiedlicher Dlatti dern ohne nennenswerten Aufwand variieren läßt. Solche Federeiemente sind pre swert 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 Unterstützungs- mittels, auf dem die Matratze liegt. Die C-Foπn sorgt für den gewünschten, progressiven Verlauf der Federcharakteristik. Gleichzeitig ist dieses Federelement über Lastungs- s icher. Anschläge zur Federwegbegrenzuπg 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 indicated in claim 1. Each spring egg thus consists of two. C-shaped, mutually facing leaf springs, which are connected at their ends. The lower and the upper leaf spring can have different material thicknesses or consist of materials of different elasticity, so that the spring hardness of the composite spring element can be varied by combining different diameters without any noteworthy effort. Such spring elements are valuable e.g. Can be made from stainless steel. They are also easy to assemble, because all you need is a screw or an equivalent fastener that fixes the lower leaf spring to the part of the frame that carries it and another screw to connect the upper leaf spring to the underside of the support on which the Mattress lies. The C-Foπn ensures the desired, progressive spring characteristic. At the same time, this spring element is safe against load. Stops to limit the travel are therefore not necessary. Likewise, no additional guides are required, but all spring elements are mounted free-standing.
Zur Verb ndung der Enden der unteren Blattfeder mit denjenigen der oberen Blattfeder kommen alle geeigneten, dem Fach- mann bekannton 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 Profilge- bm.g schon bei der Herstellung der Blattfedern berück≤ich- tigt werden kann, so daß gesonderte Arbeitsgänge wie Verschweißen, Anbringen von Bohrungen, Splinten und der- gleichen entbehrlich sind. Gewunschtenf lls können zwischen die sich umgreifenden Enden der unteren und der oberen Bla tfeder Gleitmittel, z.B. auch in Form von PTFE-Folien angeordnet werden. Dem Verwendungszweck der Federelemente 5 entsprechend, kommt es im Ergebnis nur darauf an, daß die Bl i-t: i edern an ihren Enden zuverlässig miteinander verbunden sin.:, jedoch beim Ein- und Ausfedern keine durch Reibung vt-rαrscichten Geräusche entstehen.To connect the ends of the lower leaf spring with those of the upper leaf spring, all suitable connection techniques known to the person skilled in the art can be considered. It is particularly advantageous if, according to claim 2, the ends of the lower leaf spring embrace those of the upper leaf spring in a form-fitting manner, which can be taken into account in the manufacture of the leaf springs by a corresponding profile, so that separate operations such as welding , Drilling holes, split pins and same are dispensable. If desired, lubricants, for example also in the form of PTFE films, can be arranged between the encompassing ends of the lower and upper leaf springs. In accordance with the intended use of the spring elements 5, the result is only that the blades are reliably connected to one another at their ends.

Umgek ii. t kann eine Erhöhung der Progressionswirkung sehr eLnJάt-.i dadurch erzielt werden, daß gemäß Anspruch 4 zwischen de. unteren Blattfeder und dem diese tragenden TeiJ des Rahmen; e n unterer Doppelkeil angeordnet wird. Dieser 5 Dop el kc. I, bei spiel sv/eise 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 Doppεl- 0 keile ermöglichen es, ein nahezu beliebiges Progresεion≤- verh lten e inzustellen .Reverse ii. t an increase in the progression effect very eLnJάt-.i can be achieved in that according to claim 4 between de. lower leaf spring and the part of the frame that supports it; e lower double wedge is arranged. This 5 double el kc. I, at game sv / eise made of wood or plastic, has wedge surfaces rising from the center to its ends and can also be designed so that it can be inserted later between the supporting part of the frame and the lower leaf spring. Double wedges of different strengths make it possible to set an almost arbitrary progression ratio.
Das gleich.- läßt sich gemäß Anspruch 5 alternativ oder zusätzlich durch einen oberen Doppelkeil erreichen, der zw - 5 sehe üt- ooeren Blattfeder und der Unterstützung der Matratze oder des S itzpo Lsters angeordnet wird. Wenn die Doppelkeile gemäß Anspruch 6 um 90° um die Hochachse des Federele entes drehbar sind, läßt sich die durch die Doppelkeile erzielte, erhöhte Progressionswirkung stufenweise verringern. Die geringste Progressionswirkung wird dann erh.ilten, wenn die Doppelkeile in ihrer normalen Einbau! αge verbleiben, das Federelement jedoch gemäß Anspruch 3 aus seiner normalen Einbaulage um 90° um seine Hochachse gedreht wird. AlJe vorgenannten Einstellungen lassen sich werkzt-uqloi. vo Benutzer durchführen. Der Benutzer kann daher d.i:, [■ ederungsverhalten seines Liege- oder Ξ tzmöbels in weiten Grenzen, vor allem auch bereichswei e unterschiedich, i.-.ch seinen Wünschen gestalten.The same.- can be achieved according to claim 5 alternatively or additionally by an upper double wedge, which is arranged between 5 see outer leaf spring and the support of the mattress or the seat cushion. If the double wedges can be rotated through 90 ° about the vertical axis of the spring element, the increased progression effect achieved by the double wedges can be gradually reduced. The least progression effect is obtained when the double wedges are in their normal installation! αge remain, but the spring element is rotated according to claim 3 from its normal installation position by 90 ° about its vertical axis. All the above settings can be tool-uqloi. of users. The user can therefore configure the behavior of his reclining or Ξ tz furniture within wide limits, especially in different areas, i.-.ch.
Gemäß Anspruch 7 kann der die Federelemente tragende Teil des Rahmens aus dessen Längsholmen bestehen, in welchem Fall die aui. den Federelementen sitzenden Unterstützungen der Mαtrat.'e aus den üblichen, gewöhnlich elastischen Querlatten bes ehen .According to claim 7, the part of the frame carrying the spring elements can consist of its longitudinal spars, in which case the aui. the spring elements seated supports of the Mαtrat.'e from the usual, usually elastic crossbars.

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.Frames made of longitudinal and transverse bars for reclining or seating furniture are generally known and are therefore not shown in the drawing. Rather, the drawing shows only the parts necessary for understanding the invention.
In Figur ] ist schematisch eine Querlatte 1 wiedergegeben, auf der mittels einer angedeuteten Schraube 2 eine untere, näherungsweise C-törmige, liegend angeordnete Blattfeder 3 befestigt ist, die mit ihren Enden 31 die Enden 41 einer ansonsten im wesentlichen spiegelsymmetrischen, oberen Blattfeder 4 for schiussig umgreift. Die obere Blattfeder 4 trägt einen Stützteller 5. Statt dieses Stütztellers könnte die obere Biattϊeder 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] a crossbar 1 is shown schematically, on which a lower, approximately C-shaped, lying leaf spring 3 is fastened by means of an indicated screw 2, the ends 41 of the ends 41 of an otherwise essentially mirror-symmetrical, upper leaf spring 4 for with its ends 31 grips tightly. The upper leaf spring 4 carries a support plate 5. Instead of this support plate, the upper plate 4 could also carry a conventional crossbar of a bed frame or the like, in which case the lower leaf spring 3 would be fastened on a longitudinal beam of the frame instead of on the crossbar 1.
Figur 2 zeigt, daß die untere Schraube 2 mit einer Kunststoffkappe 2.1 abgedeckt ist, die gewunschtenfalls auch die Funktion eines Puffers übernehmen kann. Die obere Blattfeder 4 ist in entsprechender Weise über eine Schraube 6 mit einer Kunststoffkappe C.l mit dem Teller 5 verbunden. Die Lage des Federelementes 3, 4 und des Tellers 5 bei Bel stung in Richtung des Pfeiles ist gestrichelt angedeutet.Figure 2 shows that the lower screw 2 is covered with a plastic cap 2.1, which can also take over the function of a buffer if desired. The upper leaf spring 4 is connected in a corresponding manner via a screw 6 with a plastic cap C1 to the plate 5. The location of the Spring element 3, 4 and the plate 5 at Bel stung in the direction of the arrow is indicated by dashed lines.
Die durch die Form der unteren Blattfeder '. bedingte Pro- gressionswirkung beim Einfedern läßt sich durch Verringerung der Breite der Unterstützungsfläche der unteren Blattfeder verkleinern. Am einfachsten geschieht dies durch Verdrehung des Federele entes 3, 4 um 90° in die in Figur gezeigt Stellung .The shape of the lower leaf spring ' . conditional progression effect during compression can be reduced by reducing the width of the support surface of the lower leaf spring. The easiest way to do this is by rotating the Federele entes 3, 4 by 90 ° in the position shown in the figure.
Umgekehrt läßt sich die Progressionswirkung erhöhen, in dem man die Unterstützungfl che der' unteren Bin t tf.edor 3 vergrößert, uzw. wie in Figur 4 dargestellt, durch Anordnung eines Doppelkeils 7a, 7b zwischen der Latte 1 und der unte- ren 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-Cörmige, zu einer Schmalseite offene Ausnehmung hat (nicht dargestellt) . Zum nachträglichen Einsetzen des Doppel eiles 7a, 7b wird im einfachsten Fall die Schraube 7 wieder herausgedreht oder einige Gewindegänge gelöst. Eine andere Möglichkeit besteht darin, die untere Blattfeder so auf der Latte 1 zu montieren, daß ein kleiner, für das seitliche Einschieben des Doppelkeiles 7a, 7b ausreichend--:}- Spalt verbleibt.Conversely, the progression effect can be increased by increasing the support area of the 'lower bin tf.edor 3, etc. As shown in FIG. 4, by arranging a double wedge 7a, 7b between the crossbar 1 and the lower leaf spring 3. The double wedge can in particular be designed such that it can also be inserted subsequently, in particular inserted from the side. For this purpose, the two wedges 7a, 7b can be connected in the middle via a thin web which has a central hole or a U-shaped recess which is open towards a narrow side (not shown). For the subsequent insertion of the double rope 7a, 7b, the screw 7 is unscrewed again in the simplest case or some threads are loosened. Another possibility is to mount the lower leaf spring on the crossbar 1 in such a way that a small gap which is sufficient for the lateral insertion of the double wedge 7a, 7b 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 90α ausschalten .The double wedge 7a, 7b can, however, also be assembled from the outset, in this case, for example, also glued to the crossbar 1, because, according to FIG. 5, the action of the double wedge 7a, 7b can be switched off by rotating the spring element 3, 4 by 90 α .
Gemäß Figur 6 kann zur weiteren Erhöhung der Progressions- Wirkung auch zwischen der oberen Blattfeder 4 und dem Tellerelement 5 ein (weiterer) Doppelkeil P.α , ob angeordnet werden .According to FIG. 6, a (further) double wedge P.α can also be arranged between the upper leaf spring 4 and the plate element 5 to further increase the progression effect become .
Wenn die auf diese eise geschaffenen Mög ichkeiten zur Veränderung der Progressionswirkung des Fedcrclementes nicht ausreichen, können schließlich auch die Doppelkeile 7a, 7b und 8α, 8b ihrersei s um 9n° um die Hochachse drehbar montiert werden (nicht dargestel t). If the possibilities created in this way for changing the progression effect of the spring element are not sufficient, the double wedges 7a, 7b and 8α, 8b can finally be mounted rotatable by 9 ° around the vertical axis (not shown).
