Description

Die Erfindung richtet sich auf ein Wasserbett mit einer Mehrzahl von parallel angeordneten, mit Wasser füllbaren, Wasserkammem bildenden Schläuchen.The invention is directed to a water bed with a plurality of hoses arranged in parallel and which can be filled with water and form water chambers.

Aus einem Prospektblatt -1983 Somma-Mattress aus den USA ist ein Wasserbett bekannt, bei dem auf einem festen Grundrahmen ein kastenförmiger Rahmen aus Polstermaterial aufgesetzt ist. In diesen Rahmen werden in Bettlängsrichtung einzelne, etwa rechteckig gestaltete, die gesamte Bettlänge überbrückende Wasserschläuche eingelegt. Anschließend wird die so gebildete Liegefläche umspannt und schließlich von einer Obermatratze um-und übergriffen.A water bed is known from a brochure -1983 Somma-Mattress from the USA, in which a box-shaped frame made of upholstery material is placed on a fixed base frame. Individual, approximately rectangular water hoses spanning the entire bed length are placed in this frame in the longitudinal direction of the bed. The lying surface formed in this way is then spanned and finally encompassed and overlapped by an upper mattress.

Bei dieser bekannten Bettkonstruktion werden alle Bewegungen an einer Seite des Bettes auf die andere Seite durch die Längsübertragung in den Wasserschläuchen als Schlingerbewegung weitergeleitet. Wird dieser Effekt von manchen Benutzern gezielt erwartet, so ist dieser für viele doch unangenehm. Ein weiterer Nachteil besteht darin, daß im Falle einer Leckage in einem Wasserschlauch eine sehr große Wassermenge ausfließt und bei einem Schaden im Mittelbereich des Bettes dieses zunächst vollständig unbrauchbar werden kann.In this known bed construction, all movements on one side of the bed are passed on to the other side by the longitudinal transmission in the water hoses as a rolling movement. If this effect is expected by some users, it is unpleasant for many. Another disadvantage is that in the event of a leak in a water hose, a very large amount of water flows out and, in the event of damage in the central region of the bed, this can initially become completely unusable.

Darüber hinaus besteht ein wesentlicher Nachteil der bekannten Bettkonstruktion darin, daß weder das Kopfteil noch das Fußteil angehoben werden kann, ohne den durch die Wasserfüllung erwünschten Federungskomfort aufgeben zu müssen.In addition, a major disadvantage of the known bed construction is that neither the head part nor the foot part can be raised without having to give up the suspension comfort desired by the water filling.

Aus der US-A-4 297 755 ist ein Wasserbett der Gattung bekannt, das allerdings für medizinische Zwecke eingesetzt werden soll. Dort sind in einzelnen Betteilen einzeln von einem Drucksteuergerät beaufschlagbare Wasserschläuche quer zur Liegerichtung des Patienten vorgesehen. Die Schläuche liegen in Fächern, die von Gurten o. dgl. gebildet werden. Dieses technisch aufwendige Bett ist für den Privatgebrauch kaum geeignet.From US-A-4 297 755 a water bed of the genus is known, which, however, is to be used for medical purposes. There, in individual bed parts, water hoses that can be acted upon individually by a pressure control device are provided transversely to the lying direction of the patient. The hoses lie in compartments which are formed by belts or the like. This technically complex bed is hardly suitable for private use.

Aus der US-A-4 346 489 ist darüberhinaus ein Bett bekannt, das eine Kammermatratze zeigt, d.h. die einzelnen Wasserkammern sind, wie bei Matratzen üblich, von flexiblen Elementen umgeben. Treten hier Störungen auf, ist die Reparatur und die Wartung sehr aufwendig. Eine vergleichsweise einfache Lösung mit großvolumigen jeweils ein Fuß-, Mittel- und Kopfteil überbrückenden Kammern zeigt die US-A-3 644 950, die ebenfalls ein Krankenhausbett betrifft.From US-A-4 346 489 a bed is also known which shows a chamber mattress, i.e. the individual water chambers are, as is usual with mattresses, surrounded by flexible elements. If faults occur here, repair and maintenance are very complex. A comparatively simple solution with large-volume chambers bridging a foot, middle and head part is shown in US Pat. No. 3,644,950, which also relates to a hospital bed.

Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der mit einfachen Mitteln ein hoher Liegekomfort, eine optimale Wartung, und insbesondere der Einsatz im privaten Bereich möglich gemacht wird, wobei, wie bei üblichen Betten für den Privatgebrauch, auch Kopf- und Fußteil verstellbar ausgebildet sein sollen und wobei bei Leckagen nur kleine Störungen auftreten sollen.The object of the invention is to provide a solution with which a high lying comfort, optimal maintenance, and in particular use in the private area is made possible with simple means, whereby, as with conventional beds for private use, the head and foot sections are also adjustable should be and only minor faults should occur in the event of leakages.

Bei einem Wasserbett der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß die Schläuche in Tragschalen angeordnet sind, die mit Fixierstegen ausgerüstet sind und daß in einer durch die Stege gebildeten Reihe oder Zeile eine Mehrzahl von ziegelartig hintereinandergefügten Schläuchen angeordnet sind.In the case of a waterbed of the type mentioned at the outset, this object is achieved according to the invention in that the hoses are arranged in carrying shells which are equipped with fixing webs and in that a number of hoses which are joined one behind the other in a row or row formed by the webs are arranged.

Durch die Erfindung wird unter Beibehaltung der Verstellbarkeit von Kopf-, Mittel- und Fußteil ein optimaler Liegekomfort erreicht. Aufgrund der Ein.! teilung einzelner Schlauchbereiche in ziegelsteinartig angeordnete Teilbereiche wird zum einen erreicht, daß einmal aufgebrachte Schwingungen nur eine vergleichsweise kurze Strecke von der Flüssigkeit weitergeleitet werden. Da die Schläuche kürzer gestaltet sind, wird gleichzeitig erreicht, daß bei einer möglichen Leckage weniger Flüssigkeit auftreten kann. Mit den Tragschalen, die beispielsweise einschließlich der Fixierstege als tiefgezogene Kunststoffwannen ausgebildet sein können, die in den Rahmenelementen des Bettes eingehängt sind und die für das jeweilige Betteil notwendigen Schläuche tragen, wird eine sehr einfache Rahmengestaltung ermöglicht, auftretende Leckagen werden di rekt von der Wanne aufgefangen u. dgl. mehr.The invention achieves optimal lying comfort while maintaining the adjustability of the head, middle and foot sections. Because of the A! Partitioning of individual hose areas into brick-like subareas is achieved, on the one hand, that vibrations, once applied, are passed on only a comparatively short distance from the liquid. Since the hoses are shorter, it is also achieved that less liquid can occur in the event of a leak. A very simple frame design is made possible with the support shells, which can be designed, for example, including the fixing webs as deep-drawn plastic tubs, which are suspended in the frame elements of the bed and carry the hoses necessary for the respective bed part, and any leaks that occur are caught directly by the tub u. Like. more.

In vorteilhafter Weise kann auch vorgesehen sein, daß die kammerbildenden Schläuche entsprechend des gewünschten Federungskomforts in Längs- und/oder Querausrichtung in den einzelnen Bettflächen angeordnet sind. So können beispielsweise gleichgerichtete Mittelflächen in den einzelnen Betteilen gebildet sein, während quer dazu angeordnete Schläuche die Randbereiche bilden u. dgl. mehr.In an advantageous manner it can also be provided that the chamber-forming hoses are arranged in the longitudinal and / or transverse orientation in the individual bed surfaces in accordance with the desired suspension comfort. For example, rectified central surfaces can be formed in the individual bed parts, while hoses arranged transversely thereto form the edge regions u. Like. more.

Besonders zweckmäßig ist es, wenn die Fixierstege einstückig an den Tragschalen ausgebildet sind, was z. B. bei der Herstellung über die Tiefziehtechnik leicht zu erreichen ist. Die Erfindung sieht auch vor, daß die Fixierstege mit eine Belüftung zulassenden Ausnehmungen ausgerüstet sind. Diese Ausnehmungen sind zweckmäßig in den oberen Bereichen der Fixierstege, um die Flüssigkeitsdichtigkeit der Tragschalen aufrechtzuerhalten, allerdings auch eine Querbelüftung durch die Bettfläche zu ermöglichen.It is particularly useful if the fixing webs are integrally formed on the support shells, which z. B. is easy to achieve in the manufacture of the deep-drawing technique. The invention also provides that the fixing webs are equipped with recesses which allow ventilation. These recesses are expedient in the upper regions of the fixing webs in order to maintain the liquid tightness of the support shells, but also to enable cross ventilation through the bed surface.

Wie oben bereits angesprochen ist es vorteilhaft, wenn in einer durch die Stege gebildeten Reihe eine Mehrzahl von ziegelsteinartig hintereinandergefügten Schläuchen angeordnet sind. Damit werden auch die Reihen oder Zeilen, die die Schläuche bilden, in sich nochmals aufgeteilt, wodurch das Federungsverhalten des Wasserbettes den jeweiligen Be dürfnissen angepaßt werden kann.As already mentioned above, it is advantageous if in a row formed by the webs a plurality of hoses are arranged one behind the other like a brick. So that the rows or lines that form the hoses are divided up again, whereby the suspension behavior of the waterbed can be adapted to the respective needs.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung. Diese zeigt in

  • Fig. 1 eine Aufsicht auf einen Bettrahmen, in
  • Fig. 2 eine perspektivische Seitenansicht eines Bettrahmens mit aufgestelltem Kopf- und angehobenem Fußteil sowie in
  • Fig. 3 einen Schnitt gemäß Linie 111 in Fig. 1.
Further features, details and advantages of the invention result from the following description and from the drawing. This shows in
  • Fig. 1 is a plan view of a bed frame, in
  • Fig. 2 is a side perspective view of a bed frame with the head and foot part raised and in
  • 3 shows a section along line 111 in FIG. 1.

Von einem in den Figuren nicht näher dargestellten Wasserbett ist ein Bettrahmen 1 dargestellt, der ein Kopfteil 2, ein Mittelteil 3 und ein Fußteil 4 aufweist. Diese Teile 2 - 4 weisen je einen eigenen Rahmen auf, der in Fig. 3 mit 5 bezeichnet ist. In diese Rahmen sind wannenförmige Tragschalen 6 eingehängt, die im dargestellten Beispiel einstückig mit querverlaufenden Fixierstegen 7 versehen sind. Diese Stege sind mit den Tragschalen z. B. im Tiefziehverfahren erstellt worden.A bed frame 1 is shown of a water bed, not shown in the figures, which has a head part 2, a middle part 3 and a foot part 4. These parts 2-4 each have their own frame, which is designated 5 in FIG. Tub-shaped support shells 6 are inserted into this frame depends, which in the example shown are provided in one piece with transverse fixing webs 7. These webs are with the support shells z. B. was created in the deep-drawing process.

Zwischen die Fixierstege sind wassergefüllte Schläuche 8 eingelegt.Water-filled hoses 8 are inserted between the fixing webs.

Wie sich aus Fig. 1 ergibt, können die Schläuche 8 unterschiedliche Abmessungen aufweisen. So sind beispielsweise im Fußteil am äußeren Fußende in einer Reihe drei Schläuche angeordnet, in der dann folgenden Reihe sind vier Teilschläuche in einer Reihe angeordnet, während die folgenden Reihen durchgehende Schläuche aufweisen. Je nach Gestaltung der Tragschalen 6 mit den Fixierstegen 7 können die Schläuche auch im Winkel zueinander diagonal oder in anderer Anordnung vorgesehen sein.As can be seen from FIG. 1, the tubes 8 can have different dimensions. For example, three hoses are arranged in a row in the foot part at the outer end of the foot, and four sub-hoses are arranged in a row in the row that follows, while the following rows have continuous hoses. Depending on the design of the support shells 6 with the fixing webs 7, the hoses can also be provided at an angle to one another diagonally or in another arrangement.

Aus Fig. 3 ergibt sich, daß die Höhe der Fixierstege 7 geringer ist als die Gesamthöhe der Wasserschläuche 8, im dargestellten Beispiel beträgt die Höhe der Fixierstege 7 weniger als die Hälfte der Höhe der Wasserschläuche 8.From Fig. 3 it follows that the height of the fixing webs 7 is less than the total height of the water hoses 8, in the example shown, the height of the fixing webs 7 is less than half the height of the water hoses 8th

Sind die Wasserschläuche 8 mit Wasser gefüllt und eingelegt, so kann eine randseitige Polsterung 9 aufgelegt werden und schließlich mit einer textilen Bespannung 10 der gesamte Rahmen überdeckt werden. Hier kann noch eine zusätzliche Polsterung vorgesehen sein.If the water hoses 8 are filled with water and inserted, an upholstery 9 can be placed on the edge and finally the entire frame can be covered with a textile covering 10. Additional padding can be provided here.

Um eine Querbelüftung zu erreichen, können nur andeutungsweise wiedergegebene Löcher 11 in den Kopfbereichen der Fixierstege 7 vorgesehen sein, damit die Luft von unten nach oben oder umgekehrt, durch die Bettfläche strömen kann.In order to achieve cross ventilation, only indicated holes 11 can be provided in the head regions of the fixing webs 7 so that the air can flow through the bed surface from bottom to top or vice versa.

Natürlich ist die Erfindung nicht auf das beschriebene Ausführungsbeispiel beschränkt. So ist das beschriebene Ausführungsbeispiel der Erfindung noch in vielfacher Hinsicht abzuändern. So ist die Erfindung nicht auf die dargestellte Verstellbarkeit nur dreier Bettflächen beschränkt, denn, wie bereits erwähnt, können auch die Wasserschläuche in anderer Anordnung vorgesehen sein oder auch nur in Teilbereichen der gesamten Fläche, während die übrige Fläche eine herkömmliche Polsterung aufweist u. dgl. mehr.Of course, the invention is not limited to the exemplary embodiment described. So the described embodiment of the invention can be modified in many ways. Thus, the invention is not limited to the adjustability shown only three bed areas, because, as already mentioned, the water hoses can be provided in a different arrangement or only in partial areas of the entire area, while the rest of the surface has conventional padding and. Like. more.
