Abstract

The mattress comprises an upper and lower parts, with support elements in the plane of a frame and connected to it. The support elements are top-open, U-shaped profiles (4) and provided on their web (6) with elastic support elements which, in the relieved and normal load state, project over the profile shanks. The U-shaped profiles are pref. algined parallel to the longitudinal direction of the frame. The frame may have at least one transverse support (9), to which the profiles can be attached on each side.

Description

Die Erfindung bezieht sich auf eine Untermatratze sowie auf ein Matratzensystem.The invention relates to a sub-mattress and to a mattress system.

Bei den bekanntesten marktgängigen Konstruktionen enthält die Untermatratze mit einem gewöhnlich rechteckigen Rahmen verbundene Tragelemente in Form von quer verlaufenden Latten, auf denen die Obermatratze liegt. Das hat den Nachteil, dass die Latten entweder sehr steif sind und praktisch keine Federwirkung haben, was sich auch durch elastische Aufhängung derselben nur teilweise ausgleichen lässt, oder, falls sie elastisch sind, eine ungleichmässige Federwirkung, die in der Mitte wesentlich stärker als am Rand ist. Im letzteren Fall hängen ausserdem, insbesondere bei breiten Betten, die Latten bei grösserer Belastung in der Mitte in unerwunschtem Mass durch. Es ist zwar eine gattungsgemässe Konstruktion bekannt (CH-506 275), bei welcher diesbezüglich durch den Einsatz eines mittleren Längsträgers und mit den Latten verbundener nach unten durchgebogener Stützlatten, die auf demselben aufliegen, eine Verbesserung der einfachen Lattenkonstruktion erreicht wird, auch andere, wo durch Einsatz von seitlich verschiebbaren Zwischenstützen und anderer Konstruktionselemente (CH-PS 483 234, CH-PS 474 982) die Schwächen der Konstruktion gemildert sind, doch können sie trotz des zum Teil beträchtlichen konstruktiven Aufwands eine intrinsische Schwäche der Lattenuntermatratze nicht beheben, nämlich, dass die Federcharakteristik nur in der Längsrichtung bis zu einem gewissen Grad gezielt variierbar und damit an die räumlich unterschiedliche Belastung anpassbar ist.In the most well-known designs on the market, the base mattress contains support elements connected to a usually rectangular frame in the form of transverse slats on which the top mattress lies. This has the disadvantage that the slats are either very stiff and have practically no spring action, which can only be partially compensated for by elastic suspension, or, if they are elastic, an uneven spring action, which is much stronger in the middle than at the edge is. In the latter case, especially with wide beds, the slats sag to an undesirable extent in the middle when the load is greater. Although a generic construction is known (CH-506 275), in which in this respect an improvement in the simple slat construction is achieved by using a central longitudinal beam and supporting slats connected to the slats and resting on the slats, and others where the use of laterally displaceable intermediate supports and other construction elements (CH-PS 483 234, CH-PS 474 982) alleviates the weaknesses of the construction, but despite the sometimes considerable construction effort, they cannot remedy an intrinsic weakness of the slatted base mattress, namely that the spring characteristic can only be varied to a certain degree in the longitudinal direction and can thus be adapted to the spatially different load.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemässe Untermatratze sowie ein Matratzensystem zu schaffen, die leicht an unterschiedliche und räumlich variierende Belastungen anpassbar sind. Die Untermatratze soll ausserdem begrenzte Federwege aufweisen.The invention has for its object to provide a generic sub-mattress and a mattress system that are easily adaptable to different and spatially varying loads. The bottom mattress should also have limited spring travel.

Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, schafft eine derartige Untermatratze, die ausserdem vorteilhafte Weiterbildungen zulässt, auf deren besondere Eigenschaften weiter unten noch hingewiesen werden wird. Besonders vorteilhaft ist die Verwendung der erfindungsgemässen Untermatratze in einem Matratzensystem, das auch eine besonders abgestimmte Obermatratze umfasst.The invention, as characterized in the claims, creates such a sub-mattress, which also permits advantageous further developments, the special properties of which will be referred to below. It is particularly advantageous to use the bottom mattress according to the invention in a mattress system that also includes a specially matched top mattress.

Im folgenden wird die Erfindung anhand von nur Ausführungsbeispiele darstellenden Figuren näher erläutert.In the following, the invention will be explained in more detail with reference to figures which only show exemplary embodiments.

Die Untermatratze weist einen steifen rechteckigen Rahmen mit einem Kopfteil 1, einem Fussteil 2 und Seitenteilen 3a,b auf sowie eine Anzahl Tragelemente (Fig. 1, 2).The bottom mattress has a rigid rectangular frame with a head part 1, a foot part 2 and side parts 3a, b and a number of supporting elements (FIGS. 1, 2).

Erfindungsgemäss sind die Tragelemente als nach oben offene U-Profile 4, die an beiden Enden durch Querwände 5 abgeschlossen sind, ausgebildet und tragen an ihren Stegen 6 befestigte elastische Stützelemente 7, welche im entlasteten bis normal belasteten Zustand über ihre Schenkel 8 hinausragen. Der Rahmen ist durch die Seitenteile 3a, 3b verbindende Querträger 9 verstärkt, an welchen, vorzugsweise einander gegenüberliegend, U-Profile 4 befestigt sind, und zwar mittels eines ihre Querwände 5 und den dazwischenliegenden Querträger 9 durchdringenden Bolzen 10, der mittels einer Mutter 11 gesichert ist. Eine Befestigung der U-Profile 4 ist natürlich auch mit anderen Mitteln möglich, etwa mit Holzschrauben oder mit Bolzen, die in eine den Querträger 9 durchdringende Gewindehülse geschraubt sind. Die Querträger 9 und die U-Profile 4 sind vorzugsweise aus - eventuell faserverstärktem - Kunststoff ausgeführt.According to the invention, the support elements are designed as upwardly open U-profiles 4, which are closed at both ends by transverse walls 5, and carry on their webs 6 attached elastic support elements 7, which protrude beyond their legs 8 in the relieved to normally loaded state. The framework is through that Reinforced cross members 9 connecting side parts 3 a, 3 b, to which, preferably opposite one another, U-profiles 4 are fastened, specifically by means of a bolt 10 penetrating their cross walls 5 and the intermediate cross member 9, which is secured by means of a nut 11. A fastening of the U-profiles 4 is of course also possible with other means, for example with wood screws or with bolts which are screwed into a threaded sleeve penetrating the cross member 9. The cross member 9 and the U-profiles 4 are preferably made of - possibly fiber-reinforced - plastic.

Nach einer ersten Ausführung (Fig. 3a,b,c) weisen die U-Profile 4 jeweils mehrere Perforationen 12 auf, die zur Befestigung eines Stützelements 7 dienen können. Die Stützelemente 7 tragen Auflageteller 13 zur Stützung der Obermatratze, die verschiedene Formen haben können, z. B. rund (Fig. 1), achteckig (Fig. 3a,b,c), sechseckig etc.. Die Verteilung der Querträger 9 kann bereits an die zu erwartende Belastungsverteilung angepasst werden, umso mehr die Verteilung der Stützelemente 7, die in zwei Dimensionen variabel ist und zwischen flächendeckend - insbesondere bei Verwendung vier- oder sechseckiger Auflageteller 13 - und relativ dünn etwa im weniger belasteten Bereich in der Nähe des Fussendes wechseln kann.According to a first embodiment (FIGS. 3a, b, c), the U-profiles 4 each have a plurality of perforations 12 which can be used to fasten a support element 7. The support elements 7 carry support plates 13 to support the top mattress, which can have different shapes, for. B. round (Fig. 1), octagonal (Fig. 3a, b, c), hexagonal etc. The distribution of the cross member 9 can already be adapted to the expected load distribution, the more the distribution of the support elements 7, which in two Dimensions is variable and can change between covering the entire area - especially when using a square or hexagonal support plate 13 - and relatively thinly in the less stressed area near the foot end.

Jedes Stützelement 7 umfasst einen ersten, äusseren Rohrabschnitt 14 aus elastischem Material, auf welchem der Auflageteller 13 sitzt und einen zweiten, inneren Rohrabschnitt 15, der vom äusseren Rohrabschnitt 14 umgeben und unten, wo das Stützelement 7 durch die durch einen Vorsprung 16 desselben und die Perforation 12 im Steg 6 des U-Profils 4 gebildete Schnappverbindung fixiert ist, mit demselben verbunden ist. Die Rohrabschnitte 14, 15 sind quer zum U-Profil 4 ausgerichtet, sodass ein Kippen des Stützelements 7 in diese Richtung durch die Schenkel 8 des U-Profils 4 verunmöglicht ist. Ausserdem weist der Auflageteller 13 zur Seitenstabilisierung des Stützelements 7 zwei Dorne 17 auf, die durch Oeffnungen im äusseren Rohrabschnitt 14 und im inneren Rohrabschnitt 15 ragen.Each support element 7 comprises a first, outer pipe section 14 made of elastic material, on which the support plate 13 sits and a second, inner pipe section 15, which is surrounded by the outer pipe section 14 and below, where the support element 7 through which by a projection 16 and the Perforation 12 in the web 6 of the U-profile 4 formed snap connection is fixed, connected to the same. The pipe sections 14, 15 are aligned transversely to the U-profile 4, so that the support element 7 tilts in this direction through the legs 8 of the U-Profile 4 is impossible. In addition, the support plate 13 for lateral stabilization of the support element 7 has two mandrels 17 which protrude through openings in the outer tube section 14 and in the inner tube section 15.

Bei geringer Belastung P wird nur der äussere Rohrabschnitt 14 deformiert, sodass das Stützelement 7 in diesem Bereich ziemlich weich ist. Erreicht die Deformation d den Wert d0 (Fig. 4) entsprechend einer Belastung P0, so sitzt der äussere Rohrabschnitt 14 auf dem inneren Rohrabschnitt 15 auf und dieser muss bei weiterer Vergrösserung der Belastung und damit der Deformation mitdeformiert werden, was eine beträchtliche Vergrösserung der Federkonstante bewirkt und weitere Deformation bremst, sodass ein hartes Aufsetzen des überstehenden Auflagetellers 13 auf die Schenkel 8 des U-Profils 4 verhindert wird. Besagtes Aufsetzen des Auflagetellers 13 verhindert im übrigen eine Beschädigung der Stützelemente 7 bei Ueberbelastung. Die Stützelemente 7 bestehen vorzugsweise aus Kunststoff, z. B. aus einem Elastomer, die Auflageteller 13 aus Hartplastik.At low load P, only the outer tube section 14 is deformed, so that the support element 7 is quite soft in this area. If the deformation d reaches the value d0 (FIG. 4) corresponding to a load P0, the outer pipe section 14 is seated on the inner pipe section 15 and this has to be deformed as the load and thus the deformation increases, which results in a considerable increase in the spring constant causes and further deformation brakes, so that a hard placement of the protruding support plate 13 on the legs 8 of the U-profile 4 is prevented. Said placement of the support plate 13 also prevents damage to the support elements 7 in the event of overload. The support elements 7 are preferably made of plastic, for. B. made of an elastomer, the support plate 13 made of hard plastic.

Nach einer zweiten Ausführungsform der erfindungsgemässen Untermatratze (Fig. 5a,b,c) enthalten die Stützelemente 7 nur einen Rohrabschnitt 14. Zur Stützung des Rohrabschnitts 14 ist in denselben ein Kautschukzylinder 18 mit in axialer Richtung durchgehenden Aussparungen 19 eingeschoben, der durch vordere Anschläge 20 und hintere Anschläge 21 fixiert ist. Das Stützelement 7 wird durch beidseitig in den Schenkeln 8 des U-Profils 4 sitzende in den Rohrabschnitt 14 ragende Haltebolzen 22 festgehalten. Das U-Profil 4 ist zur Verbesserung seiner statischen Eigenschaften durch Leisten 24 in der Fortsetzung der Schenkel 8 zu einer Struktur mit annähernd H-förmigem Querschnitt ergänzt. Zwecks Verhinderung eines harten Aufsetzens der Auflageteller 13 sind die Schenkel 8 oben mit einer Gummiauflage versehen. Alternativ können am Kautschukzylinder 18 über die Schenkel 8 ragende Fortsätze angeformt sein. Zwischen den Stützelemente 7 tragenden Stellen ist der Steg 6 durch Ausnehmungen 25 unterbrochen. Dadurch wird die Ablagerung von Staub verhindert. Der Auflageteller 13 ist bombiert und weist trapezähnliche Form auf, wobei die Basis des Trapezes konkav und die gegenüberliegende Seite entsprechend konvex gebogen ist. Das Material ist Hartplastik. Zur Verhinderung eines Verrutschens der Obermatratze ist die Oberfläche durch Erodieren oder Einätzen von Strukturen aufgerauht. Eine trapezförmige Vertiefung 26, in die Luftdurchlässe 27 münden, dient einerseits der Belüftung der Obermatratze und verstärkt andererseits die gegen ein Verrutschen derselben gerichtete Bremswirkung der Oberfläche des Auflagetellers 13. Die Verbindung zum Stützelement 7 ist durch eine Schnappverbindung hergestellt. Die Befestigung der Stützelemente 7 am U-Profil 4 erfolgt folgendermassen: die Haltebolzen 22 sind aussen an die Schenkel 8 angegegossen (Fig. 5d), weisen jedoch Sollbruchstellen auf, die erlauben, sie nach der Plazierung des Stützelements 7 nach innen zu schlagen (Pfeile), wonach sie wegen ihrer leicht konischen Ausbildung in den Schenkeln 8 festsitzen und wie bereits erläutert in den Rohrabschnitt 14 ragen und denselben fixieren.According to a second embodiment of the sub-mattress according to the invention (FIGS. 5a, b, c), the support elements 7 contain only one tube section 14. To support the tube section 14, a rubber cylinder 18 with recesses 19 that are continuous in the axial direction is inserted into it, which is supported by front stops 20 and rear stops 21 is fixed. The support element 7 is held in place by holding bolts 22 which protrude into the tube section 14 on both sides in the legs 8 of the U-profile 4. To improve its static properties, the U-profile 4 is supplemented by strips 24 in the continuation of the legs 8 to form a structure with an approximately H-shaped cross section. In order to prevent hard contact of the support plates 13, the legs 8 are provided with a rubber pad at the top. Alternatively, on Rubber cylinder 18 over the legs 8 protruding projections. The web 6 is interrupted by recesses 25 between the positions bearing the support elements 7. This prevents the build-up of dust. The support plate 13 is cambered and has a trapezoidal shape, the base of the trapezoid being concave and the opposite side being correspondingly convex. The material is hard plastic. To prevent the top mattress from slipping, the surface is roughened by eroding or etching structures. A trapezoidal recess 26, into which air passages 27 open, serves on the one hand to ventilate the top mattress and on the other hand reinforces the braking action of the surface of the support plate 13 which prevents the same from slipping. The connection to the support element 7 is established by a snap connection. The support elements 7 are attached to the U-profile 4 as follows: the retaining bolts 22 are cast onto the legs 8 on the outside (FIG. 5d), but have predetermined breaking points which allow them to be hammered inwards after the support element 7 has been placed (arrows ), after which they are stuck in the legs 8 because of their slightly conical design and, as already explained, protrude into the pipe section 14 and fix the same.

Fig. 6 zeigt die Verteilung der Stützelemente und Auflageteller. Die Form der Auflageteller 13 erlaubt eine lückenlose Ueberdeckung der vom Rahmen umschlossenen Fläche. Dabei bilden jedoch die Grenzen zwischen benachbarten Auflagetellern 13 keine durchgehenden Geraden. Ein Kippen der Stützelemente, das zur Bildung von Gräben führen könnte, wird so vermieden. Es ist möglich, Stützelemente unterschiedlicher, jeweils an die in einer bestimmten Zone zu erwartende Belastung angepasster Härte zu verwenden. Zur Erleichterung der Montage können Stützelemente unterschiedlicher Härtegrade durch unterschiedliche Färbungen der Auflageteller 13 gekennzeichnet sein.Fig. 6 shows the distribution of the support elements and support plates. The shape of the support plate 13 allows a complete coverage of the area enclosed by the frame. However, the boundaries between adjacent support plates 13 do not form any continuous straight lines. This prevents the support elements from tipping over, which could lead to the formation of trenches. It is possible to use support elements of different hardnesses, each adapted to the load to be expected in a certain zone. Support elements of different degrees of hardness can be used to facilitate assembly different colors of the support plate 13 may be marked.

In den Figuren 7a,b sind Varianten von Stützelementen 7 gezeigt, bei denen das den Rohrabschnitt 14 stützende Federelement als geschlossenporiger Schaumstoffzylinder mit Haut 28 bzw. als kunststoffüberzogene Schraubenfeder 29 aus antimagnetischem Chromnickelstahl ausgebildet ist. Die Federkennlinie ist bei den Stützelementen 7 gemäss Fig. 7a,b ebenso wie beim in Fig. 5a,b,c,d dargestellten mindestens annähernd eine Gerade.FIGS. 7a, b show variants of support elements 7 in which the spring element supporting the tube section 14 is designed as a closed-pore foam cylinder with skin 28 or as a plastic-coated coil spring 29 made of antimagnetic chromium-nickel steel. The spring characteristic is at least approximately a straight line in the support elements 7 according to FIGS. 7a, b as well as in the case of FIGS. 5a, b, c, d.

In Fig. 8 ist eine Variante mit parallelogrammförmigen Auflagetellern 13 dargestellt sowie eine mögliche Anordnung der Stützelemente in der vom Rahmen umschlossenen Fläche. Hier bilden die Grenzlinien zwischen benachbarten Stützelementen keine durchgehenden Geraden in Längsrichtung, was zur Verhinderung der Grabenbildung normalerweise genügt.8 shows a variant with parallelogram-shaped support plates 13 and a possible arrangement of the support elements in the area enclosed by the frame. Here the boundary lines between adjacent support elements do not form continuous straight lines in the longitudinal direction, which is normally sufficient to prevent the formation of trenches.

Alle Ausführungsformen haben den Vorteil, dass sie modular aufgebaut und somit ohne weiteres - durch Anpassung der Zahl nebeneinander angeordneter U-Profile in der Breite und der Zahl der Querträger 9 in der Länge - an beliebige Abmessungen anpassbar sind.All of the embodiments have the advantage that they have a modular structure and are therefore easily adaptable to any dimensions by adapting the number of adjacent U-profiles in width and the number of crossbeams 9 in length.

Eine besonders günstige Lösung wird erreicht, wenn zusätzlich zur erfindungsgemässen Untermatratze eine besonders geeignete Obermatratze verwendet wird, d. h. ein ganzes Matratzensystem, das auf die Erzielung der durch die Erfindung angestrebten Vorteile besonders abgestimmt ist.A particularly favorable solution is achieved if, in addition to the bottom mattress according to the invention, a particularly suitable top mattress is used, i. H. a whole mattress system, which is specially tailored to achieve the advantages sought by the invention.

Eine entsprechende Obermatratze ist in Fig. 9 dargestellt. Sie enthält zwischen einer oberen Auflage und einer unteren Auflage z. B. aus Rosshaar oder Textilfasern Federelemente 30.A corresponding top mattress is shown in Fig. 9. It contains between an upper edition and a lower edition z. B. horsehair or textile fibers spring elements 30th

Erfindungsgemäss besteht jedes Federelement 30 aus mehreren übereinandergestapelten und fest miteinander verbundenen Rohrabschnitten 31 aus elastischem Material, vorzugsweise einem Elastomer und weist an seinem oberen und an seinem unteren Ende je eine Auflagefläche 32 auf zur Abstützung der jeweiligen Auflage. Einzelne Rohrabschnitte 31 weisen beidseitig Verbindungselemente 33 zur Herstellung von Schnappverbindungen mit benachbarten Federelementen auf. Die Federelemente 30 können je nach der gewünschten Federcharakteristik verschieden ausgebildet sein (Fig. 10). Z. B. können einzelne Rohrabschnitte zur Versteifung horizontale Verstrebungen 34 enthalten, die bei Halbierung der ausseren Rohrabschnitte auch als Auflageflächen 32 dienen können. Federelemente 30 verschiedener Charakteristik können nach Massgabe der zu erwartenden örtlichen Belastung in der Obermatratze verteilt werden. Auch durch das Herstellen oder Nichtherstellen von Schnappverbindungen zwischen benachbarten Federelementen 30 können lokale Steifigkeit und Federeigenschaften der Obermatratze beeinflusst werden.According to the invention, each spring element 30 consists of a plurality of stacked and firmly interconnected pipe sections 31 made of elastic material, preferably an elastomer, and has a support surface 32 on its upper and lower end for supporting the respective support. Individual pipe sections 31 have connecting elements 33 on both sides for producing snap connections with adjacent spring elements. The spring elements 30 can be designed differently depending on the desired spring characteristic (FIG. 10). For example, individual pipe sections for stiffening can contain horizontal struts 34, which can also serve as support surfaces 32 if the outer pipe sections are halved. Spring elements 30 of different characteristics can be distributed in the top mattress in accordance with the expected local load. Local rigidity and spring properties of the top mattress can also be influenced by making or not making snap connections between adjacent spring elements 30.

Die beschriebenen Ausführungen von Unter- und Obermatratze eignen sich auch sehr gut für Fälle (Fig. 11), bei denen die Untermatratze mehrere gegeneinander schwenkbare Teilrahmen 35a,b,c,d,e,f enthält, die durch Scharniere 36 zwischen nebeneinanderliegenden Querträgern 9 oder auch zwischen Seitenteilen aneinanderstossender Teilrahmen verbunden sind. Die Scharniere sind zum Schutz gegen das Einklemmen von Fingern beim Verstellen der Teilrahmen mit Faltenbälgen überzogen (nicht dargestellt). Im gezeigten Beispiel befinden sich die Rahmenteile 35a,b,c am Kopfende, 35e,f am Fussende. Letztere sind wie in Fig. 12 dargestellt verbunden. Die Rahmenteile 35b,c können zur Lendenwirbelstützung einen-nach oben konvexen stumpfen Winkel bilden. Die Art ihrer Verbindung ist in Fig. 13 dargestellt.The described designs of bottom and top mattresses are also very suitable for cases (FIG. 11) in which the bottom mattress contains a plurality of subframes 35a, b, c, d, e, f which can be pivoted relative to one another and which are connected by hinges 36 between adjacent cross members 9 or are also connected between side parts of adjoining partial frames. The hinges are covered with bellows (not shown) to protect fingers from being pinched when adjusting the partial frame. In the example shown, the frame parts 35a, b, c are at the head end, 35e, f at the foot end. The latter are connected as shown in Fig. 12. The frame parts 35b, c can form an obtuse upward convex angle for lumbar support. The way of their connection is shown in Fig. 13.
