Abstract
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.The invention relates to a spring mattress in which springs are provided in a covering, which are arranged in rows next to one another and are each fixed to a stiffening grid at both ends.
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 rejected by some users of the spring mattress because it can induce small electrical currents which, in the opinion of these users, can have negative effects on the user. The well-known replacement of the coil springs by fillings made of plastic foam, hair or straws avoids the electrically conductive steel, but also eliminates the special spring effect that can be achieved with pretensioned coil springs.
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.It is therefore an object of the invention to provide a spring mattress of the type mentioned at the outset which, while maintaining the spring effect caused by coil springs, has spring elements made from a wood material. The spring mattress according to the invention is solving this problem, characterized in that the helical springs are formed by bent rattan tube.
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 tube can be bent into the shape of coil springs using techniques known per se and the rattan tube coil springs have spring mattress spring properties which are very similar to those of steel coil springs. The rattan tube coil springs also withstand the necessary preload. 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 can be easily processed in spring mattresses. Rattan cane is therefore a very suitable wood material for the spring elements of spring mattresses.
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 grids are each formed by strips or struts made of wood material. Coil springs made of rattan tube are slightly easier to bend or push away to the side than coil springs made of steel. That is why the use of stiffening grids, the strips or struts of which not only absorb tension but also pressure in the 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 are also called coil springs or coil springs. Spring mattress is not only to be understood as an elongated mattress for a bed that can be inserted into a frame, but also a cushion of a sofa or armchair that is or is permanently installed in a frame. There is usually a mat-like intermediate layer between the coil springs and the sheath. The number of rattan tube coil springs per unit area is in the order of the number of steel coil springs per unit area. The number of helical revolutions of the rattan tube helical spring is of the same order of magnitude as the number of helical revolutions of the steel helical 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 rattan tube coil springs used according to the invention consist of peeled or unpeeled rattan tube. The rattan tube is, for example, a round tubular tube with a diameter of 8-25 mm. However, the rattan tube can also be a half tube, which is obtained by splitting a full tube in the middle and whose smaller cross-sectional dimension or "half diameter" is 8-25 mm. 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 soaking a rattan tube in water, wrapping it in a soaked state on a core and letting it dry. In another type of manufacture, the rattan tube is heated in a hot gas, wound up on a core in the heated state and thus allowed to cool.
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 casing of the coil springs and their stiffening grids are e.g. formed by accommodating each coil spring in a closed sack made of textile material and arranging the sacks side by side and connecting them together, e.g. are hooked together. The connecting devices and the bags form a stiffening grid, on which the coil springs are fixed at both ends. It is also possible to combine the outer turns of each coil spring into rings and to connect the rings of adjacent coil springs to one another in order to obtain 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 under pre-tension, because this eliminates free travel of the coil springs and compensates for inequalities in the spring forces. The rattan cane coil springs can be used in the spring mattress with suitable production even without pretension. The pre-tension is reached when the bags mentioned above are sufficiently short. In the construction with the helical spring rings connected to one another, tension threads running in the axial direction of the helical springs are provided for the purpose of pretensioning.
