Description

Die vorliegende Erfindung bezieht sich auf ein Lattenrost für ein Bett gemäß dem Oberbegrift der Ansprüche 1 und 2, insbesondere für ein Bett des Wohnbereiches, mit quer zu den Längsseiten verlaufenden Federleisten und gegebenenfalls mit einem schwenkbaren Kopf- und/oder Fußteil, mit einem viereckigen Innen- und einem viereckigen Außenrahmen, die derart ineinanderlegbar sind, daß die Seiten und die Querholme aneinander oder in einem geringen Abstand zueinander liegen, daß die Federleisten an einem Rahmen angeordnet sind und daß dieser Rahmen mittels einer Verstelleinrichtung gegenüber dem anderen Rahmen zumindest anhebbar und absenkbar ist.The present invention relates to a slatted frame for a bed according to the preamble of claims 1 and 2, in particular for a bed in the living area, with transverse to the longitudinal sides of the slats and optionally with a pivotable head and / or foot part, with a square interior - And a square outer frame, which can be put into one another in such a way that the sides and the crossbars lie against one another or at a short distance from one another, that the female connectors are arranged on a frame and that this frame can be at least raised and lowered relative to the other frame by means of an adjusting device .

Bei einem aus der US-PS 3 887 950 bekannten Lattenrost ist der verstellbare Innenrahmen durch vier Laschen an dem Außenrahmen angelenkt. In der abgesenkten Position des Innenrahmens liegen diese Laschen horizontal, während sie in der angehobenen Stellung in vertikaler Richtung verlaufen. Bei diesem vorbekannten Lattenrost läßt sich die aufgelegte Matratze in zwei zum Außenrahmen parallele Stellungen verfahren. Zur Sicherung dieser beiden Stellungen ist der Innenrahmen federbelastet.In a slatted frame known from US Pat. No. 3,887,950, the adjustable inner frame is articulated on the outer frame by four straps. In the lowered position of the inner frame, these tabs are horizontal, while in the raised position they run in the vertical direction. With this previously known slatted frame, the mattress can be moved into two positions parallel to the outer frame. The inner frame is spring-loaded to secure these two positions.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Lattenrost der eingangs beschriebenen Art so zu gestalten, daß der höhenverstellbare Rahmen in jeder Höhenlage parallel zum feststehenden Rahmen oder auch in einer Schrägstellung stehen kann.The present invention has for its object to design a slatted frame of the type described above so that the height-adjustable frame can be parallel to the fixed frame or in an inclined position at any height.

Die gestellte Aufgabe wird gemäß einem ersten Vorschlag gelöst, indem das Lattenrost in ein vorhandenes Bettgestell einlegbar ist und die Verstelleinrichtung zwei dem Kopf- und dem Fußende des Lattenrostes zugeordnete Hubgestänge aufweist, daß jedes Hubgestänge aus zwei Antriebslenkern und zwei Abtriebslenkern gebildet ist, die auf in den Holmen des feststehenden Rahmens drehbaren Bolzen oder einer durchgehenden Achse drehfest aufgesetzt sind, daß die freien Enden der Antriebslenker durch eine Koppelstange miteinander verbunden sind, und daß mindestens ein Linearantrieb mit einem linear bewegbaren Antriebsglied an der Koppelstange und dem Abtriebslenker angelenkt ist.The object is achieved according to a first proposal in that the slatted frame can be inserted into an existing bed frame and the adjusting device has two lifting rods assigned to the head and foot ends of the slatted frame, such that each lifting rod is formed from two drive links and two output links, which on in the spars of the fixed frame rotatable bolt or a continuous axle are rotatably mounted that the free ends of the drive links are connected by a coupling rod, and that at least one linear drive is articulated with a linearly movable drive member on the coupling rod and the output link.

Dieser Vorschlag ist nur dann zu realisieren, wenn der Betreiber den höhenverstellbaren Rahmen ausschließlich in eine zum feststehenden Rahmen parallele Stellung bringen will. Ein Antriebslenker und ein Abtriebslenker bilden immer eine Funktionseinheit, die an einem Längsholm des feststehenden Rahmens gelagert sind. Durch die beidseitige Unterstützung des höhenverstellbaren Rahmens im Kopf- und Fußbereich wird ein seitliches Kippen vermieden. Soll der höhenverstellbare Rahmen jedoch auch in eine Schräglage zum feststehenden Rahmen bringbar sein, ist zur Lösung der gestellten Aufgabe gemäß einem zweiten Vorschlag vorgesehen, daß das Lattenrost in ein vorhandenes Bettgestell einlegbar ist und die Verstelleinrichtung zwei jeweils dem Kopf- und dem Fußende zugeordnete Hubgestänge aufweist, daß jedes Hubgestänge aus zwei Antriebslenkern und zwei Abtriebslenkern gebildet ist, die auf in den Holmen des feststehenden Außenrahmens drehbaren Bolzen oder einer durchgehenden Achse drehfest aufgesetzt sind, daß die freien Enden der Antriebslenker mit jeweils einem Linearantrieb mit einem linear bewegbaren Abtriebsglied gekoppelt sind und daß die anderen Enden der Linearantriebe an den Seitenholmen des feststehenden Außenrahmens angelenkt sind. Bei dieser Ausführung entfällt die Koppelstange, die durch die an jeder Seite des Lattenrostes vorgesehenen Linearantriebe ersetzt wird. Da die Linearantriebe unabhängig voneinander steuerbar sind, läßt sich innerhalb des Verstellbereiches der höhenverstellbare Rahmen in jede Winkellage zum feststehenden Rahmen bringen. Werden die Antriebs- und die Abtriebslenker auf einer durchgehenden Achse drehfest aufgesetzt, könnte der Linearantrieb bzw. bei der zweiten Ausführung die Linearantriebe mittig liegen.This proposal can only be implemented if the operator only wants to bring the height-adjustable frame into a position parallel to the fixed frame. A drive link and an output link always form a functional unit, which are mounted on a longitudinal spar of the fixed frame. The double-sided support of the height-adjustable frame in the head and foot area prevents sideways tipping. However, if the height-adjustable frame can also be brought into an inclined position relative to the fixed frame, this is the solution to the problem According to a second proposal, it is provided that the slatted frame can be inserted into an existing bed frame and the adjusting device has two lifting rods assigned to the head and foot ends, that each lifting rod is formed from two drive links and two output links, which are mounted on the spars of the fixed outer frame rotatable bolt or a continuous axis are rotatably mounted that the free ends of the drive links are each coupled to a linear drive with a linearly movable output member and that the other ends of the linear drives are articulated on the side rails of the fixed outer frame. In this version there is no coupling rod, which is replaced by the linear drives provided on each side of the slatted frame. Since the linear drives can be controlled independently of one another, the height-adjustable frame can be brought into any angular position to the fixed frame within the adjustment range. If the drive and output links are mounted on a continuous axle so that they cannot rotate, the linear drive or, in the second embodiment, the linear drives could be in the center.

Bei einer Ausführung mit mehr als einem Linearantrieb kann es passieren, daß bei einer Parallelverschiebung des Rahmens ein Linearantrieb stärker belastet wird als der andere, wodurch sich unterschiedliche Geschwindigkeiten der Abtriebsglieder ergeben, wodurch bewirkt wird, daß der verstellbare Rahmen in eine ungewollte Neigung gebracht wird. Um dieses zu verhindern, ist vorgesehen, daß die Koppelstange als teleskopierbare Stange ausgebildet ist, daß an der Koppelstange der eine Linearantrieb angehängt ist, wobei ein Ende des Linearantriebes an einem Teil der teleskopierbaren Koppelstange und das gegenüberliegende Ende des Linearantriebes an dem anderen Teil der Koppelstange angelenkt ist. Durch den an die Koppelstange angehängten Linearantrieb läßt sich dann die Länge der Koppelstange so verändern, daß der verstellbare Rahmen immer in einer Parallellage zum feststehenden Rahmen steht. Dieser Linearantrieb ist im Sinne eines Ausgleichelementes oder eines Überbrückungsgliedes zu sehen. Die Linearantriebe sind vorzugsweise elektromotorische Antriebe, da dann die Verstellung beispielsweise durch Knopfdruck erfolgen kann.In a version with more than one linear drive, it can happen that when the frame is displaced in parallel, one linear drive is loaded more than the other, which results in different speeds of the output elements, which causes the adjustable frame to be brought into an undesired inclination. To prevent this, it is provided that the coupling rod is designed as a telescopic rod, that a linear drive is attached to the coupling rod, one end of the linear drive on a part of the telescopic coupling rod and the opposite end of the linear drive the other part of the coupling rod is articulated. Due to the linear drive attached to the coupling rod, the length of the coupling rod can then be changed so that the adjustable frame is always in a parallel position to the fixed frame. This linear drive can be seen in the sense of a compensating element or a bridging element. The linear drives are preferably electromotive drives, since the adjustment can then be carried out, for example, by pressing a button.

Damit der höhenverstellbare Rahmen sich nicht in Längsrichtung verschiebt, ist vorgesehen, daß zumindest an einem dem Kopf- oder Fußteil zugeordneten Abtriebslenker ein Ende eines Führungsstabes gelagert ist, dessen Länge halb so groß ist wie die des Abtriebslenkers, daß das gegenüberliegende Ende an dem höhenverstellbaren Rahmen angelenkt und daß der Führungsstab, bezogen auf die Länge des Abtriebslenkers, in der Mitte des Abtriebslenkers gelagert ist. Dieser Führungsstab ist im Sinne eines Blockiergliedes zu sehen, der entweder dem Kopf- oder dem Fußteil zugeordnet ist, jedoch zweckmäßigerweise an jedem Längsholm des höhenverstellbaren Rahmens gelagert ist. Da er halb so lang ist wie der Abtriebslenker ergibt sich eine kinematische Zwangsführung zwischen dem Innen- und dem Außenrahmen, die bewirkt, daß der Innenrahmen sich beim Anheben nicht in Längsrichtung relativ zum Außenrahmen verschieben kann. Da bei einer Höhenverstellung des verstellbaren Rahmens zwischen den freien Enden der Abtriebslenker und dem verstellbaren Rahmen Relativbewegungen erzeugt werden, ist zur Verminderung der Reibung vorgesehen, daß an jedem freien Ende des Abtriebslenkers eine Stützrolle frei drehbar gelagert oder ein Gleitschuh befestigt ist.So that the height-adjustable frame does not move in the longitudinal direction, it is provided that at least one end of a guide rod is mounted on at least one output link assigned to the head or foot part, the length of which is half as long as that of the output link, that the opposite end on the height-adjustable frame articulated and that the guide rod, based on the length of the output link, is mounted in the middle of the output link. This guide rod can be seen in the sense of a blocking member, which is assigned to either the head part or the foot part, but is expediently mounted on each longitudinal spar of the height-adjustable frame. Since it is half as long as the output link, there is a kinematic positive guidance between the inner and the outer frame, which means that the inner frame can not move in the longitudinal direction relative to the outer frame when lifting. Since with a height adjustment of the adjustable frame between the free ends of the output link and the adjustable frame relative movements are generated, it is provided to reduce the friction that at each free end of the output link a support roller is freely rotatably mounted or a slide shoe is attached.

Aus Darstellungsgründen sind in den Fig. 1 bis 3 die sich quer zu den Längsholmen erstreckenden Federleisten sowie die um Querachsen verstellbaren Rücken- und Fußteile nicht dargestellt. Die in den Fig. 1 und 2 dargestellten Lattenroste 10 beinhalten jedweils einen Außenrahmen 11 und einen gegenüber dem Außenrahmen 11 höhenverstellbaren Innenrahmen 12. Die beiden ineinanderlegbaren Rahmen sind in ein vorhandenes Bettgestell derart einlegbar, daß sich der Außenrahmen 11 am Bettgestell abstützt. Die in den Figuren linken Enden der Lattenroste 10 können sowohl das Kopf- als auch das Fußteil sein. Das andere Ende könnte demzufolge ebenfalls das Kopf- oder das Fußteil sein. In den Fig. 1 bis 3 sind nur die einer Längsseite des Lattenrostes 10 zugeordneten Teile der Verstelleinrichtung dargestellt. Die andere Seite ist in der gleichen Weise gestaltet und wird deshalb nicht beschrieben.For reasons of illustration, the spring strips extending transversely to the longitudinal spars and the back and foot parts which can be adjusted about transverse axes are not shown in FIGS. 1 to 3. The slatted frames 10 shown in FIGS. 1 and 2 each include an outer frame 11 and an inner frame 12 which is height-adjustable in relation to the outer frame 11. The two nested frames can be inserted into an existing bed frame in such a way that the outer frame 11 is supported on the bed frame. The left ends of the slatted frames 10 in the figures can be both the head part and the foot part. The other end could therefore also be the head or foot section. 1 to 3, only the parts of the adjusting device assigned to a longitudinal side of the slatted frame 10 are shown. The other side is designed in the same way and is therefore not described.

Am rechten Ende des Längsholmes des Außenrahmens 11 ist ein Bolzen 13 drehbar gelagert. Auf diesem Bolzen ist ein nach unten rechtwinklig zum Holm des Außenrahmens 11 stehender Antriebslenker 14 und ein wesentlich längerer, unter einem stumpfen Winkel zum Antriebslenker 14 stehender Abtriebslenker 15 drehfest aufgesetzt. Am linken Ende des Holmes des Außenrahmens 11 ist ein weiterer Bolzen 16 drehbar eingesetzt, auf dem wiederum ein Antriebslenker 17 und ein Abtriebslenker 18 drehfest aufgesetzt ist. Die Antriebslenker 14 und 17 sowie die Abtriebslenker 15 und 18 stehen in jeder Höhenlage des Innenrahmens 12 parallel zueinander. In der oberen Endstellung des Innenrahmens 12 stehen die Antriebslenker 14 und 17 rechtwinklig zum Holm des Außenrahmens 11 nach unten. Der Abstand des linken Bolzens 16 zum linken Stirnende des Außenrahmens 11 ist etwas größer als die Länge der Abtriebslenker 15, 18. Die freien Enden der Antriebslenker 14, 17 sind durch eine Koppelstange 19 miteinander verbunden, die in den Ausführungen nach den Fig. 1 und 3 parallel zum Außenrahmen 11 steht, wenn sich der Innenrahmen 12 gemäß den Darstellungen in der oberen Endstellung befindet. Die Höhenverstellung des Innenrahmens 12 erfolgt bei der Ausführung nach der Fig. 1 über einen Linearantrieb 20, der mit einem Ende an dem Antriebslenker 15 und mit seinem anderen Ende in der Mitte der jeweiligen Koppelstange 19 angelenkt ist. Bei der Darstellung sind die in linearer Richtung bewegbaren Abtriebsglieder ausgefahren. Beim Ein- oder Ausfahren dieser Abriebsglieder werden die Antriebslenker 14, 17 und somit auch die Abtriebslenker 15, 18 im gleichen Drehsinn geschwenkt. An die den Linearantrieben 20 gegenüberliegenden Abtriebsgliedern 18 sind Führungsstäbe 21 angelenkt, deren Länge halb so groß ist wie die Abtriebslenker 18. Die anderen Enden der Führungsstäbe 21 sind an den Längsholmen des Innenrahmens 12 drehbar gelagert. Die Führungsstäbe 21 sind, bezogen auf die Länge der Abtriebsglieder 18, mittig angelenkt. Aus der zuvor beschriebenen Anordnung der Elemente 14 bis 21 ergibt sich, daß der Innenrahmen 12 und der Außenrahmen 11 in jeder Position parallel zueinanderliegen und daß der Außenrahmen 11 und der Innenrahmen 12 relativ zueinander keine Längsbewegung ausführen können. Die Linearantriebe 20 sind so ausgelegt, daß sie den Innenrahmen 12 in jeder Stellung halten. Die freien Enden aller Abtriebslenker 15 tragen jeweils eine frei drehbar gelagerte Stützrolle 22. Auf diesen Stützrollen 22 stützen sich die Seitenholme des Innenrahmens 12 ab. Durch die Rollen wird die Reibung vermindert. Anstelle der Rollen könnten jedoch auch Gleitschuhe aus einem geeigneten Material Verwendung finden.At the right end of the longitudinal spar of the outer frame 11, a bolt 13 is rotatably mounted. On this bolt, a drive link 14 standing at right angles to the spar of the outer frame 11 and a much longer output link 15 standing at an obtuse angle to the drive link 14 are non-rotatably mounted. At the left end of the spar of the outer frame 11, a further pin 16 is rotatably inserted, on which in turn a drive link 17 and an output link 18 are non-rotatably mounted. The drive link 14 and 17 and the output link 15 and 18 are parallel to each other at any height of the inner frame 12. In the upper end position of the inner frame 12, the drive links 14 and 17 are at right angles to the spar of the outer frame 11 downwards. The distance of the left bolt 16 to the left end of the outer frame 11 is slightly larger than the length of the output link 15, 18. The free ends of the drive link 14, 17 are connected to each other by a coupling rod 19 which in the 1 and 3 is parallel to the outer frame 11 when the inner frame 12 is in the upper end position as shown. The height adjustment of the inner frame 12 takes place in the embodiment according to FIG. 1 via a linear drive 20 which is articulated at one end to the drive link 15 and at the other end in the middle of the respective coupling rod 19. In the illustration, the output elements that can be moved in the linear direction are extended. When these abrasion members are extended or retracted, the drive links 14, 17 and thus also the output links 15, 18 are pivoted in the same direction. Guide rods 21 are articulated to the output members 18 opposite the linear drives 20, the length of which is half the length of the output links 18. The other ends of the guide rods 21 are rotatably mounted on the longitudinal bars of the inner frame 12. The guide rods 21 are articulated in relation to the length of the output members 18. From the arrangement of the elements 14 to 21 described above it follows that the inner frame 12 and the outer frame 11 are parallel to each other in any position and that the outer frame 11 and the inner frame 12 can not perform any longitudinal movement relative to each other. The linear drives 20 are designed so that they hold the inner frame 12 in any position. The free ends of all output links 15 each carry a freely rotatable support roller 22. The side rails of the inner frame 12 are supported on these support rollers 22. The rollers reduce friction. Instead of the rollers, however, sliding shoes made of a suitable material could also be used Find.

Die Ausführung gemäß der Fig. 2 ist geeignet, um den mit den Federleisten bestückten Innenrahmen 12 in eine Schräglage zum Außenrahmen 11 zu bringen. Anstelle der Koppelstange 19 ist bei dieser Ausführung an jeder Seite ein Linearantrieb vorgesehen. Der zusätzliche Linearantrieb ist durch das Bezugszeichen 23 gekennzeichnet. Durch eine nicht dargestellte Steuerung können die kopf- und fußseitigen Linearantriebe 20, 23 unabhängig voneinander betätigt werden. An den einander zugewandt liegenden Enden sind die Linearantriebe 20, 23 bei dieser Ausführung an den Seitenholmen des Innenrahmens 12 angeschlagen. Die Stellung der in der Fig. 2 dargestellten Antriebslenker 17 und der Abtriebslenker 18 entspricht der Ausführung nach der Fig. 1. Die in der Fig. 2 rechten Antriebslenker 14 zeigen in der angehobenen Stellung des Innenrahmens 12 in Richtung zum Innenrahmen 12. Ein weiterer Unterschied zu der Ausführung nach der Fig. 1 besteht darin, daß die Abtriebsglieder der Linearantriebe 20, 23 an den freien Enden der Antriebslenker 14 und 17 angelenkt sind.The embodiment according to FIG. 2 is suitable for bringing the inner frame 12 equipped with the female connectors into an inclined position relative to the outer frame 11. Instead of the coupling rod 19, a linear drive is provided on each side in this embodiment. The additional linear drive is identified by reference number 23. The head and foot side linear drives 20, 23 can be actuated independently of one another by a control, not shown. In this embodiment, the linear drives 20, 23 are attached to the side rails of the inner frame 12 at the ends facing one another. The position of the drive link 17 and the output link 18 shown in FIG. 2 corresponds to the embodiment according to FIG. 1. The drive link 14 on the right in FIG. 2 point in the raised position of the inner frame 12 in the direction of the inner frame 12. Another difference 1 is that the output members of the linear drives 20, 23 are hinged to the free ends of the drive links 14 and 17.

Die Ausführung nach der Fig. 3 zeigt wiederum eine Ausführung mit einem zusätzlichen Linearantrieb 25. Bei dieser Ausführung ist die Koppelstange 19 zweigeteilt und demzufolge teleskopierbar. An diese Koppelstange ist der zusätzliche Linearantrieb 25 angehängt. Das in der Darstellung linke Ende ist an einem Teil der Koppel stange 19 und das in der Darstellung rechte Ende des Linearantriebes 25 an dem anderen Ende der Koppel stange angelenkt. Mittels des Linearantriebes 25 ist die Länge der Koppelstange 19 veränderbar. Ansonsten entspricht der Aufbau der Ausführung gemäß der Fig. 1. Durch Bewegen des Abtriebsgliedes des Linearantriebes 25 ergeben sich unterschiedliche Winkelstellung der Hebel 15 und 18 zueinander, wodurch eine Neigung des Innenrahmens 12 um eine Querachse relativ zum Außenrahmen 11 erreicht wird. Wird die Koppelstange auf eine Länge, wie in Fig. 3 dargestellt, gebracht, so stehen beide Rahmen 11 und 12 parallel zueinander und lassen sich bei Betätigung des Linearantriebes 20 genauso parallel zueinander verschieben, wie es auch bei der Ausführung in Fig. 1 möglich ist. Die in den Figuren aufgezeigten Ausführungen sind beispielhaft zu sehen, da für die Höhenverstellung des mit den Federleisten bestückten Rahmens viele Ausführungen denkbar sind. Die dargestellten Linearantriebe können an jeder Seite des Lattenrostes vorgesehen sein. Es ist jedoch auch denkbar, daß die Linearantriebe nur an einer Seite liegen, wobei dann die andere Seite über entsprechende Stangen oder Mitnehmer mit verstellt wird. Ferner ist es denkbar, daß die Linearantriebe im Bereich der Mitte des Lattenrostes liegen und die Verbindung zu den Antriebslenkern bzw. Koppelstangen über Achsen oder Wellen hergestellt wird.The embodiment according to FIG. 3 in turn shows an embodiment with an additional linear drive 25. In this embodiment, the coupling rod 19 is divided into two and can therefore be telescoped. The additional linear drive 25 is attached to this coupling rod. The left end in the illustration is rod on a part of the coupling rod 19 and the right end of the linear drive 25 in the illustration rod is articulated on the other end of the coupling rod. The length of the coupling rod 19 can be changed by means of the linear drive 25. Otherwise, the construction corresponds to the embodiment according to FIG. 1. Moving the output member of the linear drive 25 results in different angular positions of the levers 15 and 18 relative to one another, as a result of which the inner frame 12 is inclined relative to the outer frame 11 about a transverse axis. If the coupling rod is brought to a length, as shown in FIG. 3, then both frames 11 and 12 are parallel to one another and can be moved parallel to one another when the linear drive 20 is actuated, as is also possible in the embodiment in FIG. 1 . The designs shown in the figures are to be seen as examples, since many designs are conceivable for the height adjustment of the frame equipped with the female connectors. The linear drives shown can be provided on each side of the slatted frame. However, it is also conceivable that the linear drives are only on one side, with the other side being adjusted with corresponding rods or drivers. Furthermore, it is conceivable that the linear drives are located in the area of the center of the slatted frame and the connection to the drive links or coupling rods is established via axes or shafts.
