Description
Die Erfindung betrifft einen Taschenfederkern mit mehreren, nebeneinander liegenden und miteinander verbundenen, gemeinsam eine Nutzfläche bildenden Federsträngen, von denen jeder eine Vielzahl von in einer Reihe hintereinander angeordnete, aus Draht schraubenförmig gewundene Federn aufweist, die jeweils von einer Tasche umhüllt sind, wobei alle Taschen eines Federstrangs aus einem einstückigen flexiblen, vorzugsweise textilen Material gebildet sind und benachbarte Federstränge bäuchlings der eingetaschten Federn miteinander verbunden sind.The invention relates to a pocket spring core with a plurality of juxtaposed and interconnected, together forming a useful spring strands, each of which has a plurality of one behind the other arranged in a row of wire helically wound springs, each of which is enveloped by a bag, all bags a spring strand of a one-piece flexible, preferably textile material are formed and adjacent spring strands are connected to each other belly of the eingetaschten springs together.
Derartige Taschenfederkerne sind hinlänglich bekannt und finden vornehmlich als Basiselement bei der Herstellung von Matratzen Verwendung. Dabei zeichnet sich der bekannte Taschenfederkern dadurch aus, dass die einzelnen Federn eines Federstrangs von einem einstückigen, üblicherweise Textilmaterial umhüllt werden, wobei die Taschen, die die einzelnen Federn aufnehmen, dadurch gebildet werden, dass die beidseitig an den Federn anliegenden Streifen des Hüllmaterials in den zwischen zwei Federn gebildeten Bereichen miteinander verbunden werden, beispielsweise durch Verkleben oder Verschweißen. Mittels einer solchen Verbindung wird die jeweilige Tasche auch öffnungsseitig verschlossen.Such pocket spring cores are well known and find primarily as a base element in the production of mattresses use. In this case, the known pocket spring core is characterized by the fact that the individual springs of a spring strand are enveloped by a one-piece, usually textile material, wherein the pockets which receive the individual springs, are formed by the fact that the applied to both sides of the strips of the envelope material in the be formed between two springs formed areas, for example by gluing or welding. By means of such a connection, the respective pocket is also closed on the opening side.
Die direkt aneinander liegenden benachbarten Federstränge werden bäuchlings der eingetaschten Federn miteinander verklebt, wobei quasi eine unmittelbare Anlage jeweils zweier Federn benachbarter Federstränge gegeben ist, lediglich getrennt durch die zweifache Dicke des Hüllmaterials, wodurch eine kompakte Anordnung der Federstränge möglich ist.The adjacent adjacent spring strands are glued to each other belly of the eingetaschten springs together, with quasi an immediate Plant each two springs adjacent spring strands is given, only separated by twice the thickness of the shell material, whereby a compact arrangement of the spring strands is possible.
Allerdings sind die einzelnen Federn relativ groß dimensioniert, sowohl hinsichtlich ihrer Höhe wie auch ihres Durchmessers, so dass die Verwendungsfähigkeit eines gattungsgemäßen Federkerns eingeschränkt ist.However, the individual springs are relatively large dimensions, both in terms of their height as well as their diameter, so that the usefulness of a generic spring core is limited.
Insbesondere ist es nicht möglich, diese Federkern, vom Benutzer akzeptiert, beispielsweise in Sitzmöbeln einzusetzen, da hier eine andere Federcharakteristik verlangt wird als bei Matratzen.In particular, it is not possible to use this spring core, accepted by the user, for example, in seating, since here a different spring characteristic is required as in mattresses.
Es ist daher schon versucht worden, sogenannte Mini-Taschenfederkerne zu kreieren, deren Taschen jedoch abweichend von der Gattung, aus zwei separaten Materialstreifen gebildet werden, die ober- und unterseitig über die einzelnen Federn geführt sind und an sich gegenüberliegenden Bauchseiten durch Verschweißen oder Verkleben miteinander verbunden sind. D.h., jeder gebildete Federstrang weist auf beiden Längsseiten, etwa in der Bauchmitte der Federn eine Naht auf, wobei zur Verbindung, sowohl zum Verschweißen wie auch zum Verkleben eine gewisse Randbreite dieser Naht erforderlich ist, so dass dieser Rand übersteht.It has therefore already been attempted to create so-called mini-pocket spring cores, but their pockets are deviating from the genus, formed of two separate strips of material, which are above and below the individual springs out and on opposite sides of the abdomen by welding or gluing together are connected. In other words, each spring strand formed has a seam on both longitudinal sides, for instance in the middle of the belly of the springs, whereby a certain edge width of this seam is required for the connection, both for welding and for bonding, so that this edge protrudes.
Bei der Verbindung der Federstränge miteinander ergibt sich so der Nachteil eines relativ großen Abstandes der Federstränge zueinander, so dass der Federungskomfort nicht in dem gewünschten Maße gegeben ist.When connecting the spring strands with each other so the disadvantage of a relatively large distance of the spring strands to each other, so that the suspension comfort is not given in the desired dimensions.
Der Erfindung liegt die Aufgabe zugrunde, einen Taschenfederkern der gattungsgemäßen Art so weiterzuentwickeln, dass seine Verwendungsfähigkeit verbessert wird.The invention has for its object to further develop a pocket spring core of the generic type so that its usefulness is improved.
Diese Aufgabe wird durch einen Taschenfederkern mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a pocket spring core with the features of claim 1.
Dadurch, dass zumindest ein Teil der Federn einen größten Durchmesser von 20 bis 30 mm und eine Höhe von 35 - 80 mm aufweisen, die quasi in einstückigen Taschen positioniert sind, ist eine sehr dichte Packung auch dieser sehr kleinen Federn möglich, so dass ein solcher Taschenfederkern in akzeptierter Weise vor allem bei hochwertigen Polstermöbeln, bei Inlays für Kissen, sogenannten high-end-Toppern oder bei Matratzen, bei denen zwei Taschenfederkerne übereinander angeordnet sind und die einen besonderen Liegekomfort aufweisen, eingesetzt werden kann.The fact that at least a portion of the springs have a maximum diameter of 20 to 30 mm and a height of 35 - 80 mm, which are virtually positioned in one-piece pockets, a very dense packing of these very small springs is possible, so that such Pocket spring core in accepted manner, especially in high-quality upholstered furniture, inlays for pillows, so-called high-end Toppern or mattresses, where two pocket spring cores are arranged one above the other and which have a special lying comfort, can be used.
Der neue Federkern ist extrem flexibel und kann sich vielfältigst den unterschiedlichen Formen anpassen, so dass er selbst in Lehnen von Polstermöbeln oder in faltbaren Kopfkissen Verwendung finden kann, dank der eingesetzten Materialien, Verbundart und Federkonstruktion.The new spring core is extremely flexible and can be adapted in many different ways to the different shapes, so that it can be used even in upholstery of upholstered furniture or in foldable pillows, thanks to the materials used, type of composite and spring construction.
Nach einer vorteilhaften Weiterbildung der Erfindung ist der größte Durchmesser jeder einzelnen, vorzugsweise tonnenförmigen, im Bedarfsfall aber auch zylindrischen Feder 26 mm, während die Höhe variieren kann und zwar im Bereich von 45 bis 70 mm. Bevorzugt sind alle Federn des Taschenfederkerns gleich. Denkbar ist aber auch, je nach Bedarf, innerhalb der genannten Abmaße unterschiedliche Federn zu verwenden.According to an advantageous embodiment of the invention, the largest diameter of each individual, preferably barrel-shaped, if necessary, but also cylindrical spring 26 mm, while the height can vary in the range of 45 to 70 mm. Preferably, all springs of the pocket spring core are the same. It is also conceivable, depending on requirements, within the specified dimensions to use different springs.
Wie sich gezeigt hat, ist eine Drahtstärke der schraubenförmig gewundenen Federn von 0,8 bis 1,15 mm besonders vorteilhaft, da hierdurch, in Abstimmung mit den anderen Abmaßen, eine optimale Federcharakteristik erreicht wird. Prinzipiell sind jedoch auch davon abweichende Drahtstärken denkbar, beispielsweise in einem Bereich von 0,6 bis 1,3 mm.As has been shown, a wire thickness of the helically wound springs of 0.8 to 1.15 mm is particularly advantageous, as this, in coordination with the other dimensions, an optimum spring characteristic is achieved. In principle, however, deviating wire thicknesses are also conceivable, for example in a range of 0.6 to 1.3 mm.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
