Definitions

  • the invention relates to an upper mattress for a mattress system consisting of an upper and a lower mattress according to the preamble of claim 1.
  • top mattresses with spring cores containing spiral springs have essentially the same spring characteristics everywhere. As a result, their flexibility does not correspond to the expected load in all areas of the bed. In addition, spiral springs are relatively complicated to manufacture and install and, as metal parts, represent an undesirable foreign body in the top mattress.
  • an upper mattress with spring elements is known, each of which is formed from a plurality of wave-like curved strips, which are glued together in sections and extend over the entire length or width, so that the spring elements form horizontal and transverse prismatic elements.
  • the strips can be made from a fiber composite material.
  • the spring elements each extend over the entire extent of the mattress, flexible adaptation of the spring characteristics to locally expected loads is not possible. Obviously, it is also not intended to achieve adaptability in this regard.
  • the spring elements are not easy to assemble, since the longitudinal and transverse elements cross and one must be pulled through one of the prismatic elements of the other.
  • the above-mentioned elements are likely to be deformed predominantly at the edges during deflection, so that fatigue fractures are to be feared there.
  • the invention is based on the object of creating a generic top mattress with spring elements, the spring characteristics of which can be adapted to different local loads.
  • the top mattress according to the invention is very easy to assemble and can be adapted to locally different loads. Due to their shape, the spring elements have favorable characteristics and are very resilient and durable.
  • the top mattress also allows further training, the special properties of which are referred to below. In particular, it can easily be made entirely of plastic and textile or textile-like materials.
  • the top mattress (Fig. 1) contains between an upper edition and a lower edition e.g. B. horsehair or textile fibers spring elements 1.
  • each spring element 1 consists of a plurality of stacked and firmly interconnected pipe sections 2 made of elastic material, preferably an elastomer, and has a support surface 3 on its upper and lower end for supporting the respective support.
  • Individual pipe sections 2 have connecting elements 4 on both sides for producing snap connections with adjacent spring elements.
  • the spring elements 1 can be designed differently depending on the desired spring characteristic (Fig. 2).
  • individual pipe sections for stiffening can contain horizontal struts 5, which can also serve as contact surfaces 3 if the outer pipe sections are halved.
  • Spring elements 1 of different characteristics can be distributed in the top mattress according to the expected local load. Local stiffness and spring properties of the top mattress can also be influenced by making or not making snap connections between adjacent spring elements 1.

Description

  • Die Erfindung betrifft eine Obermatratze für ein aus einer Ober- und einer Untermatratze besetehendes Matratzensystem gemäss dem Oberbegriff des Anspruchs 1.
  • Herkömmliche Obermatratzen mit Spiralfedern enthaltenden Federkernen weisen im wesentlichen überall die gleiche Federcharakteristik auf. Dadurch entspricht ihre Nachgiebigkeit nicht in allen Bereichen des Bettes der zu erwartenden Belastung. Ausserdem sind Spiralfedern in Herstellung und Einbau verhältnismässig kompliziert und stellen als Metallteile einen unerwünschten Fremdkörper in der Obermatratze dar.
  • Aus der DE-A-29 42 174 ist eine Obermatratze mit Federelementen bekannt, welche jeweils aus mehreren sich über die ganze Länge oder Breite erstreckenden wellenartig gebogenen, abschnittsweise miteinander verklebten Streifen gebildet sind, so dass die Federelemente horizontal und quer verlaufende prismatische Elemente bilden. Die Streifen können aus einem Faserverbundwerkstoff hergestellt sein. Da sich die Federelemente jeweils über die ganze Ausdehnung der Matratze erstrecken, ist jedoch eine flexible Anpassung der Federcharakteristik an lokal zu erwartende Belastungen nicht möglich. Diesbezügliche Anpassungsfähigkeit zu erreichen, ist offenbar auch nicht beabsichtigt.
  • Zudem sind die Federelemente nicht einfach zu montieren, da sich Längs- und Querelemente kreuzen und eines jeweils durch eines der prismatischen Elemente des anderen durchgezogen werden muss. Die erwähnten Elemente dürften bei Einfederung überwiegend an den Kanten deformiert werden, sodass dort Ermüdungsbrüche zu befürchten sind.
  • Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine gattungsgemässe Obermatratze zu schaffen mit Federelementen, deren Federcharakteristik an unterschiedliche lokale Belastungen anpassbar ist.
  • Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des unabhängigen Patentanspruchs 1 angegebenen Merkmale gelöst. Weitere Merkmale der Erfindung sind Gegenstand der abhängigen Ansprüche 2 bis 5.
  • Die durch die Erfindung erreichten Vorteile sind vor allem darin zu sehen, dass die erfindungsgemässe Obermatratze sehr einfach zu montieren und an örtlich unterschiedliche Belastungen anpassbar ist. Die Federelemente weisen durch ihre Form günstige Charakteristiken auf und sind sehr belastbar und dauerhaft. Die Obermatratze erlaubt zudem Weiterbildungen, auf deren besondere Eigenschaften weiter unten noch hingewiesen wird. Insbesondere kann sie ohne weiteres vollständig aus Kunststoff und textilen oder textilartigen Materialien hergestellt werden.
  • Im folgenden wird die Erfindung anhand von nur ein Ausführungsbeispiel darstellenden Figuren näher erläutert. Es zeigen
    • Fig. 1
    angeschnitten eine Obermatratze gemäss der Erfindung
    und
    Fig. 2
    mehrere Ausführungsformen eines Bestandteils (Federelement) einer Obermatratze gemäss der Erfindung.
  • Die Obermatratze (Fig. 1) enthält zwischen einer oberen Auflage und einer unteren Auflage z. B. aus Rosshaar oder Textilfasern Federelemente 1.
  • Erfindungsgemäss besteht jedes Federelement 1 aus mehreren übereinandergestapelten und fest miteinander verbundenen Rohrabschnitten 2 aus elastischem Material, vorzugsweise einem Elastomer und weist an seinem oberen und an seinem unteren Ende je eine Auflagefläche 3 auf zur Abstützung der jeweiligen Auflage. Einzelne Rohrabschnitte 2 weisen beidseitig Verbindungselemente 4 zur Herstellung von Schnappverbindungen mit benachbarten Federelementen auf. Die Federelemente 1 können je nach der gewünschten Federcharakteristik verschieden ausgebildet sein (Fig. 2). Z. B. können einzelne Rohrabschnitte zur Versteifung horizontale Verstrebungen 5 enthalten, die bei Halbierung der äusseren Rohrabschnitte auch als Auflageflächen 3 dienen können. Federelemente 1 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 1 können lokale Steifigkeit und Federeigenschaften der Obermatratze beeinflusst werden.
