Abstract

Described is a mattress support framework comprising an array (1) of flexible slats (2) running perpendicular to the longitudinal axis of the bed, each slat consisting of two laminae (6, 7) located one above the other and held a given distance apart by moulded elastic elements (3). Mounted on the underside of the lower lamina (7) of each slat (2) are elastic mounting elements (4) which support the bed framework (1) on a solid frame.

Description

Die Erfindung bezieht sich auf Einlage für ein Bett in Form eines Lattenrostes mit quer zur Bettlängsachse verlaufenden Federlatten, die jeweils aus zwei übereinander liegenden, durch elastische Formkörper auf Abstand zueinander gehaltenen Lamellen gleicher Länge bestehen, wobei an der Unterseite der unteren Lamellen elastische Stützkörper vorgesehen sind, über die sich die Einlage an einem festen Einsatz abstützt.The invention relates to an insert for a bed in the form of a slatted frame with spring slats extending transversely to the longitudinal axis of the bed, each consisting of two superimposed slats of the same length, which are spaced apart by elastic molded bodies, elastic support bodies being provided on the underside of the lower slats , over which the insert is supported on a fixed insert.

Eine ähnliche Einrichtung ist durch EP-B1-151 218 bekanntgeworden. In der erwähnten Druckschrift fehlen allerdings noch die in der Zwischenzeit offenkundig vorbenutzten elastischen Stützkörper zwischen unteren Lamellen und festem Einsatz.A similar device has become known from EP-B1-151 218. In the mentioned publication, however, the elastic support body between the lower slats and the fixed insert, which has obviously been used in the meantime, is still missing.

Bei der bekannten Einrichtung besteht der feste Einsatz aus zwei Längsträgern, welche mit seitlichem Abstand von den Enden der Federlatten verlaufen. Mit einer derartigen Anordnung ist nur sehr schwer ein einigermaßen befriedigender Elastizitätsverlauf quer zur Längserstreckung des Bettes zu erreichen: es läßt sich kaum vermeiden, daß entlang der abstützenden Längsträger wie auch entlang der Längssymmetrieachse Bereiche wesentlich verringerter Nachgiebigkeit der Unterlage entstehen, wobei überdies die Seitenränder die Tendenz zeigen, sich unschön nach oben aufzubiegen.In the known device, the fixed insert consists of two longitudinal beams, which run at a lateral distance from the ends of the spring slats. With such an arrangement, it is very difficult to achieve a reasonably satisfactory elasticity curve transverse to the longitudinal extension of the bed: it can hardly be avoided that areas of substantially reduced flexibility of the support arise along the supporting longitudinal beams as well as along the longitudinal axis of symmetry, with the side edges also showing the tendency show to unsightly bend upwards.

Die Erfindung erreicht demgegenüber einen harmonischen Verlauf der Nachgiebigkeit der Einlage bei gleichzeitiger Begrenzung ihrer Durchbiegung, indem elastische Stützkörper zumindest in der Mitte der auch an ihren Enden unterstützten unteren Lamellen vorgesehen sind.In contrast, the invention achieves a harmonious course of the flexibility of the insert while at the same time limiting its deflection, in that elastic support bodies are provided at least in the middle of the lower slats, which are also supported at their ends.

Obwohl es die wesentliche Aufgabe der Erfindung ist, das Durchhängen zweiteiliger Federlatten elastisch zu begrenzen, ist es sinnvoll, auch die Enden der Federlatten elastisch abzustützen, um die Nachgiebigkeit des Lattenrostes quer zur Längsrichtung des Bettes möglichst gleichförmig zu machen. Üblicherweise wird man daher auch an den Enden der unteren Lamellen elastische Stützkörper vorsehen.Although it is the essential object of the invention to limit the sagging of two-part spring slats elastically, it makes sense to elastically support the ends of the spring slats in order to make the flexibility of the slatted frame transverse to the longitudinal direction of the bed as uniform as possible. Usually, elastic support bodies will therefore also be provided at the ends of the lower slats.

Zweckmäßig ist es, in beispielsweise aus EP-A1-385 121 bekannter Weise die Stütz- und/oder Formkörper benachbarter Federlatten miteinander zu verbinden bzw. diese aus einem einheitlichen Elastikkörper, insbesondere aus Latex, herzustellen. Die Verbindung zwischen den Stütz- und Formkörpern einerseits und den Lamellen andererseits kann dabei ebenfalls wie in EP-A1-385 121 dargestellt durch Umhüllen der elastischen Körper mit einem Gewebe und Durchstecken der Lamellen durch Laschen der Umhüllung erfolgen. Die Verbindung der Stütz- bzw. Formkörper in Längsrichtung hat den Vorteil, daß damit die Federlatten zu einem einheitlichen Rost verbunden sind, welcher einfach gehandhabt und beispielsweise auch eingerollt werden kann.It is expedient to connect the supporting and / or molded bodies of adjacent spring slats to one another in a manner known, for example, from EP-A1-385 121, or to produce them from a uniform elastic body, in particular from latex. The connection between the support and molded bodies on the one hand and the lamellae on the other hand can also take place, as shown in EP-A1-385 121, by covering the elastic body with a tissue and pushing the lamellae through by lashing the cover. The connection of the support or molded body in the longitudinal direction has the advantage that the spring slats are connected to a uniform grate, which can be easily handled and rolled up, for example.

Eine konstruktiv einfache Lösung für die seitlichen Stützkörper ist dadurch gekennzeichnet, daß die an den Enden der unteren Lamellen angeordneten elastischen Stützkörper einstückig mit den zur Distanzierung der oberen und unteren Lamellen ausgebildeten Formkörpern sind. Elastische Stützkörper, über die sich Federlatten an einem festen Einsatz abstützen, sind an sich aus EP-A-0 274 371 bekannt. Sie können jedoch nur entweder zur Aufnahme von zwei Lamellen oder zur Abstützung an einer Unterlage dienen. Eine hinreichende Elastizität des Formkörpers ist nämlich nur dann gegeben, wenn eine seiner beiden Bohrungen frei bleibt. Dort wo die Federlatte abgestützt ist, muß sie immer einteilig sein.A structurally simple solution for the lateral support bodies is characterized in that the elastic support bodies arranged at the ends of the lower slats are in one piece with the shaped bodies designed for spacing the upper and lower slats. Elastic support bodies, by means of which spring slats are supported on a fixed insert, are known per se from EP-A-0 274 371. However, they can only be used to hold two slats or to support them on a base. A sufficient elasticity of the shaped body is only given if one of its two bores remains free. Where the spring slat is supported, it must always be in one piece.

Umgekehrt kann nur im ungestützten Bereich eine die zweite Bohrung durchdringende Lamelle zur Versteifung der tragenden Lamelle vorgesehen sein.Conversely, a lamella penetrating the second bore can be provided for stiffening the supporting lamella only in the unsupported area.

Ein wesentlicher Vorteil der erfindungsgemäß vorgesehenen mittigen Anordnung der elastischen Stützkörper für die unteren Lamellen besteht darin, daß hierdurch die Nachgiebigkeit der verschiedenen in Längsrichtung des Bettes aufeinanderfolgenden Federlatten variiert werden kann. Verschiebt man nämlich die zwischen den Enden der Lamellen und deren Mitte angeordneten distanzierenden Formkörper zu den Enden hin, biegt sich die obere Lamelle völlig durch und wird gemeinsam mit der unteren Lamelle im wesentlichen vom mittig angeordneten Stützkörper gehalten. Schiebt man die distanzierenden Formkörper hingegen weiter zur Mitte, kommt es zu einer wesentlichen Versteifung der Federlatten, da eine Durchbiegung nur mehr möglich ist, wenn die distanzierenden Formkörper und der mittig angeordnete Stützkörper komprimiert werden. Am besten funktioniert dieses Zusammenspiel von Lamellen und Form- bzw. Stützkörpern, wenn die Lamellen nicht dicker sind als etwa 5 - 6 mm, wogegen die Form- und Stützkörper aus geschäumtem Material, insbesondere aus geschäumtem Gummi, gefertigt sind.A major advantage of the central arrangement of the elastic support bodies for the lower slats provided according to the invention is that the resilience of the various spring slats that follow one another in the longitudinal direction of the bed can be varied. If one moves the spacing shaped bodies arranged between the ends of the lamellae and their middle towards the ends, the upper lamella bends completely and is held together with the lower lamella essentially by the centrally arranged support body. If, on the other hand, the distancing molded body is pushed further towards the center, the spring slats are substantially stiffened, since deflection is only possible if the distancing molded body and the centrally arranged support body are compressed. This interplay of lamellas and molded or supporting bodies works best if the lamellas are not thicker than about 5 - 6 mm, whereas the molded and supporting bodies are made of foamed material, especially of foamed rubber.

Weitere Einzelheiten der Erfindung werden anschließend anhand der Zeichnungen erläutert.Further details of the invention are explained below with reference to the drawings.

In dieser stellt Fig. 1 einen festen Einsatz von der Seite, Fig. 2 den selben Einsatz von oben, Fig. 3 einen erfindungsgemäßen Lattenrost von oben, Fig. 4 den eingelegten Lattenrost im Querschnitt durch den festen Einsatz dar. Fig. 5 zeigt ein Ausführungsbeispiel für am Rand der Lamellen anzuordnende Stützkörper, Fig. 6 einen Stützkörper zur Anordnung im Mittelbereich der Lamellen, Fig. 7 eine Alternative zu Fig. 6.1 shows a fixed insert from the side, FIG. 2 shows the same insert from above, FIG. 3 shows a slatted frame according to the invention from above, FIG. 4 shows the inserted slatted frame in cross section through the fixed insert. FIG. 5 shows Exemplary embodiment for support bodies to be arranged at the edge of the slats, FIG. 6 a support body for arrangement in the central region of the slats, FIG. 7 an alternative to FIG. 6.

Der in Fig. 1 und 2 dargestellte feste Einsatz 5 weist zwei Seitenlängsträger 16 und einen Mittellängsträger 17 auf, auf welchen sich der später zu beschreibende Lattenrost abstützen kann. Es ist dabei nicht notwendig, daß der Einsatz 5 eine völlig horizontale Unterlage für den Lattenrost bildet. Es kann im Gegenteil vorteilhaft sein, zur Erhöhung des Fußbereiches eine Auflage 14 vorzusehen und den Kopfteil 15 überhaupt um eine Achse 12 schwenkbar zu machen. Dadurch ist es möglich, diesen Kopfteil mittels Zahnleisten 11 in wählbarer Winkelstellung an einer Haltestange 13 festzulegen.The fixed insert 5 shown in FIGS. 1 and 2 has two side rails 16 and a center rail 17, on which the slatted frame to be described later can be supported. It is not necessary that the insert 5 forms a completely horizontal base for the slatted frame. On the contrary, it can be advantageous to provide a support 14 to increase the foot area and to make the head part 15 pivotable about an axis 12 at all. This makes it possible to fix this head part by means of toothed strips 11 in a selectable angular position on a holding rod 13.

Auf die beschriebene Einlage 5 wird der in Fig. 3 dargestellte Lattenrost 1 aufgelegt, welcher aus einer großen Anzahl nebeneinander angeordneter und durch Haltebänder 8 verbundener Federlatten 2 besteht. Diese Federlatten 2 sind jeweils aus einer oberen Lamelle 6 und einer unteren Lamelle 7 aufgebaut, zwischen denen elastische Formkörper 3,3' angeordnet sind. Die erfindungsgemäße Abstützung der unteren Lamellen 7 erfolgt über elastische Stützkörper 4,4' entweder an den Seitenlängsträgern 16 oder am Mittellängsträger 17 des festen Einsatzes 5.The slatted frame 1 shown in FIG. 3, which consists of a large number of spring slats 2 arranged next to one another and connected by holding straps 8, is placed on the insert 5 described. These spring slats 2 are each constructed from an upper lamella 6 and a lower lamella 7, between which elastic molded bodies 3, 3 'are arranged. The lower slats 7 are supported according to the invention via elastic support bodies 4, 4 ′ either on the side longitudinal members 16 or on the central longitudinal member 17 of the fixed insert 5.

Der Aufbau der Formkörper 3,3' bzw. Stützkörper 4,4' geht aus Fig. 5 und 6 deutlicher hervor. Im Endbereich der Federlatten 2 sind die Formkörper 3', deren Ausnehmungen 10 in bekannter Weise die oberen und unteren Lamellen 6 bzw. 7 aufnehmen, einstückig mit den zur unteren Abstützung dienenden Stützkörpern 4' ausgebildet. Die Stützkörper nebeneinanderliegender Federlatten 2 sind durch ein gemeinsames Halteband 8 aus Baumwolle verbunden.The structure of the molded body 3, 3 'or support body 4, 4' can be seen more clearly from FIGS. 5 and 6. In the end region of the spring slats 2, the shaped bodies 3 ', the recesses 10 of which receive the upper and lower lamellae 6 and 7 in a known manner, are formed in one piece with the supporting bodies 4' serving for lower support. The supporting bodies of spring slats 2 lying next to one another are connected by a common holding strap 8 made of cotton.

Um ein Herausziehen der Lamellen 6,7 aus den Ausnehmungen 10 zu verhindern, können im Inneren der Ausnehmungen 10 Vorsprünge vorgesehen sein, welche in Bohrungen eingreifen, welche an den Enden der Lamellen 6,7 vorgesehen sind.In order to prevent the slats 6, 7 from being pulled out of the recesses 10, inside the recesses 10 projections can be provided which engage in bores which are provided at the ends of the slats 6, 7.

Im Mittelbereich der Federlatten 2 sind die Stützkörper 4 gemäß Fig. 6 ausgebildet. Sie umgreifen also lediglich mit ihren oberen Randleisten 9 die darüberliegenden Lamellen 7 und sind daher leicht auf diesen verschiebbar. Diese leichte Verschiebbarkeit ist für jene Formkörper erwünscht, welche sich zwischen den mittleren Stützkörpern 4 und den kombinierten Stütz- und Formkörpern im Randbereich befinden (vgl. Fig. 4). Diese Formkörper 3 können identisch aufgebaut sein wie der in Fig. 6 dargestellte Stützkörper 4. Durch seitliche Verschiebung der Formkörper 3 läßt sich die Steifigkeit des Lattenrostes 1 quer zur Bettlängsrichtung variieren.The support bodies 4 according to FIG. 6 are formed in the central region of the spring slats 2. They therefore only grip around the upper slats 7 with their upper edge strips 9 and are therefore easily displaceable on them. This easy displaceability is desirable for those moldings which are located between the middle support bodies 4 and the combined support and moldings in the edge region (cf. FIG. 4). These shaped bodies 3 can be constructed identically to the support body 4 shown in FIG. 6. The rigidity of the slatted frame 1 can be varied transversely to the longitudinal direction of the bed by lateral displacement of the shaped bodies 3.

Statt einzelner Formkörper 3 und Stützkörper 4 vorzusehen, kann - wie in Fig. 7 dargestellt ist - ein über die ganze Länge der Einlage 1 durchgehender Stützkörper 4 vorgesehen sein. Um die einzelnen Latten an diesem Stützkörper zu befestigen, kann dieser in bekannter Weise mit einem Gewebe 18 umhüllt sein, wobei Laschen 19 die Befestigung der Latten erlauben.Instead of providing individual molded bodies 3 and support bodies 4, a support body 4 can be provided over the entire length of the insert 1, as shown in FIG. 7. In order to attach the individual slats to this support body, it can be covered with a fabric 18 in a known manner, with tabs 19 allowing the slats to be attached.
