Description

Die Erfindung betrifft eine Sprungfedermatratze, bei der in einer Umhüllung Sprungfedern vorgesehen sind, die in Reihen nebeneinander angeordnet sind und beiderends an je einem Versteifungsgitter festgelegt sind. Einedeartige Sprungfedermatratze ist Z.B. aud der FR-A-426 046 bekannt.The invention relates to a spring mattress, in which in a Wrapping springs are provided in rows next to each other are arranged and both ends on a stiffening grid are set. Such a spring mattress is e.g. known from FR-A-426 046.

Die Wendelfedern einer durch die Praxis bekannten Sprungfedermatratze bestehen aus Stahl. Das Stahlmaterial wird von manchen Benutzern der Sprungfedermatratze abgelehnt, weil darin kleine elektrische Ströme induziert werden können, die nach Ansicht dieser Benutzer negative Wirkungen auf den Benutzer haben können. Der bekannte Ersatz der Wendelfedern durch Füllungen aus Kunststoffschaumstoff, Haaren oder Halmen vermeidet zwar den elektrisch leitenden Stahl, beseitigt aber auch den mit vorgespannten Wendelfedern erreichbaren speziellen Federungseffekt.The coil springs of a spring mattress known from practice are made of steel. The steel material is from some users of the spring mattress rejected because small electrical currents can be induced in it according to these users negative effects on the user can have. The well-known replacement of the coil springs through fillings made of plastic foam, hair or straws avoids the electrically conductive steel, eliminated but also the one that can be reached with preloaded coil springs special suspension effect.

Eine Aufgabe der Erfindung ist es also, eine Sprungfedermatratze der eingangs genannten Art zu schaffen, die unter Wahrung des durch Wendelfedern bedingten Federungseffektes Federelemente aus einem Holzmaterial aufweist. Die erfindungsgemäße Sprungfedermatratze ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß die Wendelfedern von gebogenem Rattanrohr gebildet sind.An object of the invention is therefore a spring mattress of the type mentioned at the outset, while respecting the spring effect caused by helical springs made of a wood material. The invention Spring mattress is, by solving this task characterized in that the coil springs of curved Rattan tube are formed.

Rattanrohr läßt sich mit an sich bekannten Techniken in die Form von Wendelfedern biegen und die Rattanrohr-Wendelfedern haben Sprungfedermatratze-Federeigenschaften, die denen von Stahl-Wendelfedern sehr ähnlich sind. Die Rattanrohr-Wendelfedern halten auch die erforderliche Vorspannung gut aus. Die äußeren Abmessungen der brauchbaren RattanrohrWendelfedern sind denen von Stahl-Wendelfedern vergleichbar, so daß die Rattanrohr-Wendelfedern ohne weiteres in Sprungfedermatratzen verarbeitbar sind. Rattanrohr ist also ein für die Federelemente von Sprungfedermatratzen sehr geeignetes Holzmaterial.Rattan cane can be made using techniques known per se Bend the shape of coil springs and the rattan tube coil springs have spring mattress spring properties that are very similar to those of steel coil springs. The rattan cane coil springs also maintain the required preload good. The outer dimensions of the usable rattan cane coil springs are comparable to those of steel coil springs, so that the rattan tube coil springs easily in spring mattresses are processable. Rattan cane is one for them Spring elements of spring mattresses very suitable Wood material.

Besonders zweckmäßig und vorteilhaft ist es, wenn die Versteifungsgitter jeweils von Leisten bzw. Streben aus Holzmaterial gebildet sind. Wendelfedern aus Rattanrohr sind etwas leichter ausbiegbar bzw. seitlich wegdrückbar als Wendelfedern aus Stahl. Deshalb ist der Einsatz von Versteifungsgittern, deren Leisten bzw. Streben nicht nur Zug, sondern auch Druck in Längsrichtung aufnehmen, sinnvoll. Das Holzmaterial ist z.B. Rattanrohr.It is particularly expedient and advantageous if the stiffening grid each of strips or struts made of wood material are formed. Coil springs made of rattan are slightly lighter can be bent out or pushed away laterally as helical springs Steel. That is why the use of stiffening grids, their Last or strut not only pull, but also pressure in Take longitudinal direction, makes sense. The wood material is e.g. Rattan cane.

Die Wendelfedern werden auch Schraubenfedern oder Sprungfedern genannt. Unter Sprungfedermatratze ist nicht nur eine längliche Matratze für ein Bett zu verstehen, die in ein Gestell einlegbar ist, sondern auch ein Polster eines Sofas oder eines Sessels, das in ein Gestell fest eingebaut wird oder ist. Zwischen den Wendelfedern und der Umhüllung befindet sich in der Regel noch eine mattenartige Zwischenschicht. Die Zahl der Rattanrohr-Wendelfedern pro Flächeneinheit liegt in der Größenordnung der Zahl der Stahl-Wendelfedern pro Flächeneinheit. Auch die Zahl der Wendelumläufe der Rattanrohr-Wendelfeder liegt in der Größenordnung der Zahl der Wendelumläufe der Stahl-Wendelfeder.The coil springs also become coil springs or coil springs called. There is not just one under spring mattresses elongated mattress for a bed to understand that in a frame is insertable, but also a cushion of a sofa or one Armchair that is or is permanently installed in a frame. Between the coil springs and the casing is in the Usually another mat-like intermediate layer. The number of Rattan cane coil springs per unit area are of the order of magnitude the number of steel coil springs per unit area. Also the number of spiral revolutions of the rattan tube spiral spring is in the order of the number of helical revolutions of the Steel coil spring.

Rattanrohr wird auch Peddigrohr genannt. Die erfindungsgemäß verwendeten Rattanrohr-Wendelfedern bestehen aus geschältem oder ungeschältem Rattanrohr. Das Rattanrohr liegt z.B. als im Querschnitt rundes Vollrohr mit einem Durchmesser von 8-25 mm vor. Das Rattanrohr kann jedoch auch ein Halbrohr sein, das durch mittiges Spalten eines Vollrohres anfällt und dessen kleinere Querschnittsabmessung bzw. "Halbdurchmesser" bei 8-25 mm liegt. Der Durchmesser des Stahldrahtes der Stahl-Wendelfedern liegt bei ca. 2 mm.Rattan cane is also called rattan cane. The invention Rattan tube coil springs used consist of peeled or unpeeled rattan tube. The rattan tube is e.g. as Cross section of round solid tube with a diameter of 8-25 mm in front. However, the rattan tube can also be a half tube, that occurs through the central splitting of a full pipe and its smaller cross-sectional dimension or "half diameter" at 8-25 mm lies. The diameter of the steel wire of the steel coil springs is approx. 2 mm.

Die Rattanrohr-Wendelfeder läßt sich z.B. herstellen, indem ein Rattanrohr in Wasser eingeweicht wird, im eingeweichten Zustand auf einen Kern gewickelt wird und so trocknen gelassen wird. Bei einer anderen Herstellungsart wird das Rattanrohr in einem Heißgas erhitzt, im erhitzten Zustand auf einen Kern gewickelt und so abkühlen gelassen.The rattan tube coil spring can be e.g. manufacture by a Rattan tube is soaked in water when soaked is wound on a core and left to dry becomes. In another type of manufacture, the rattan tube is in heated by a hot gas, wound on a core when heated and let it cool down.

Die Umhüllung der Wendelfedern und deren Versteifungsgitter sind z.B. gebildet, indem jede Wendelfeder in einem geschlossenen Sack aus Textilmaterial untergebracht ist und die Säcke nebeneinander angeordnet und miteinander verbunden, z.B. miteinander verhakt sind. Die Verbindungseinrichtungen und die Säcke bilden ein Versteifungsgitter, an dem die Wendelfedern beiderends festgelegt sind. Es ist auch möglich, die äußeren Windungen jeder Wendelfeder zu Ringen zusammenzufassen und die Ringe benachbarter Wendelfedern miteinander zu verbinden, um das gewünschte Versteifungsgitter zu erhalten.The wrapping of the coil springs and their stiffening grid are e.g. formed by each coil spring in a closed Sack made of textile material and the sacks arranged side by side and connected to each other, e.g. together are hooked. The connecting devices and the Sacks form a stiffening grid on which the coil springs are fixed at both ends. It is also possible to use the outer Combine the turns of each helical spring into rings and to connect the rings of neighboring coil springs with each other, to get the desired stiffening grid.

Die Rattanrohr-Wendelfedern sind in der Regel eingebaut in der Sprungfedermatratze unter Vorspannung gehalten, weil hierdurch Leerwege der Wendelfedern beseitigt werden und Ungleichheiten der Federkräfte ausgeglichen werden. Die Rattanrohr-Wendelfedern lassen sich in der Sprungfedermatratze bei geeigneter Fertigung auch ohne Vorspannung einsetzen. Die Vorspannung ist erreicht, wenn die vohrer erwähnten Säcke ausreichend kurz sind. Bei der Bauweise mit den miteinander verbundenen Wendelfeder-Ringen werden zwecks Vorspannung in axialer Richtung der Wendelfedern verlaufende Spannfäden vorgesehen.The rattan tube coil springs are usually installed in the Spring mattress kept under tension because of this Free travel of the coil springs and inequalities are eliminated the spring forces are balanced. The rattan cane coil springs can be in the spring mattress use suitable manufacturing without pretensioning. The Preload is reached when the bags mentioned above are sufficiently short. When building with each other connected coil spring rings are used for pretensioning Tensioning threads running in the axial direction of the coil springs intended.
