Description

Die Erfindung betrifft eine Taschenfederkernmatratze mit Taschenfedern in in Reihen und Zeilen angeordneten Federtaschen gemäß dem Oberbegriff des ersten Schutzanspruches.The invention relates to a pocket spring mattress with pocket springs arranged in rows and rows of spring pockets according to the preamble of the first claim for protection.

Taschenfederkernmatratzen sind in vielerlei Ausführungsformen bekannt, DE 10 2012 107 053 A1 , die in der Regel Taschenfedern aus Federstahl aufweisen, die in Federtaschen vorgespannt eingesetzt sind, die in Reihen und Zeilen in einer solchen Federkernmatratze verbaut sind, wobei zum Erhalt einer Mindeststeifigkeit eine solchen Federkernmatratze parallel zu den Reihen von Taschenfedern verlaufende Verstärkungsstreifen verbaut sind. Ein weiteres Beispiel der Taschenfederkernmatratze mit Taschenfedern aus Kunststoff ist aus US 2008/128965 A1 bekannt.Pocket spring mattresses are known in many forms, DE 10 2012 107 053 A1 , which generally have pocket springs made of spring steel, which are inserted pretensioned in spring pockets, which are installed in rows and rows in such a spring mattress, reinforcement strips running parallel to the rows of pocket springs being installed in order to obtain a minimum stiffness. Another example of the pocket spring mattress with pocket springs made of plastic is made of US 2008/128965 A1 known.

Nachteilig an den bekannten Taschenfederkernmatratzen ist jedoch, dass die Taschenfedern aus üblicherweise Metall gefertigt sind, sodass Personen, die ein vollständige Metallfreiheit ihrer Schlafstätte bevorzugen oder sogar benötigen, nicht in den Genuss einer Taschenfederkernmatratze kommen können. Ungünstig an den verwendeten Taschenfedern aus Metalldraht ist des Weiteren, dass sie nur sehr dünne untere und obere Auflagerflächen des oberen und unteren Drahtringes zur Verfügung stellen, sodass die Federtaschen einem erhöhten Verschleiß unterliegen, was die Lebensdauer einer damit ausgestatteten Taschenfederkernmatratze wesentlich vermindert. Unvorteilhaft ist bei aus Metalldraht gefertigten Taschenfedern zudem, dass sie aufgrund von Feuchtigkeit in der Taschenfederkernmatratze korrodieren können, sofern sie nicht aus nichtrostendem Stahl gefertigt oder entsprechend beschichtet sind, was deren Wirtschaftlichkeit verringert. Aufgabe der Erfindung ist es, eine Taschenfederkernmatratze zur Verfügung zu stellen, die einen geringeren Metallanteil aufweist oder sogar vollkommen metallfrei ausgebildet ist und die eine hohe Lebensdauer aufweist.A disadvantage of the known pocket spring mattresses, however, is that the pocket springs are usually made of metal, so that people who prefer or even need complete freedom from metal in their sleeping place cannot enjoy a pocket spring mattress. Another disadvantage of the pocket springs made of metal wire is that they only provide very thin lower and upper bearing surfaces of the upper and lower wire ring, so that the spring pockets are subject to increased wear, which significantly reduces the service life of a pocket spring mattress equipped with them. It is also disadvantageous for pocket springs made of metal wire that they can corrode due to moisture in the pocket spring mattress, provided that they are not made of stainless steel or coated accordingly, which reduces their economy. The object of the invention is to provide a pocket spring mattress which has a lower metal content or is even completely metal-free and which has a long service life.

Die Lösung dieser Aufgabe wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst.This object is achieved according to the invention by the subject matter of the independent claim.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den nachfolgenden Unteransprüchen.Further advantageous embodiments of the subject matter of the invention result with and in combination from the following subclaims.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung sind die Taschenfedern einteilig aus einem dauerelastischen Kunststoff gefertigt, insbesondere gespritzt, sodass sich die Taschenfedern schnell und kostengünstig in beliebig großer Anzahl herstellen lassen.According to a particularly preferred embodiment of the invention, the pocket springs are made in one piece from a permanently elastic plastic, in particular injection molded, so that the pocket springs can be produced quickly and inexpensively in any number.

Ein weiterer wesentlicher Vorteil besteht darin, dass verschiedene Taschenfedern in den unterschiedlichsten Wandstärken hergestellt werden können, ebenso wie aus den unterschiedlichsten Kunststoffen, wie auch mit den unterschiedlichsten Gestaltungen der Federelemente, wodurch auf einfachste Art und Weise Einfluss auf die Federraten genommen werden kann, sodass damit Taschenfederkernmatratzen gefertigt werden können, die in unterschiedlichen Bereichen oder Zonen die unterschiedlichsten Unterstützungsgrade aufweisen können.Another major advantage is that different pocket springs can be manufactured in a wide variety of wall thicknesses, as well as from a wide variety of plastics, as well as with a wide variety of spring element designs, which means that spring rates can be influenced in the simplest way, so that Pocket spring mattresses can be made, which can have different levels of support in different areas or zones.

Eine vorteilhaft ausgestaltete Taschenfeder weist dabei eine kreiszylindrische oder tonnenförmige Grundform auf, mit bevorzugt ringförmig ggf. geschlossen ausgeführten oberen und unteren Auflagerflächen, die die von den Federtaschen aufzunehmenden Druckbelastungen deutlich reduzieren. Die zwischen den Auflagerflächen angeordneten elastischen Federelemente sparen bevorzugterweise in einem um ihre Mittellängsachse herum einen sie von oben bis unten durchtretenden Freiraum auf, sodass eine mit den erfinderischen Taschenfedern ausgestattete Taschenfederkernmatratze hervorragend belüftet ist und jegliche Feuchtigkeit sofort aus der Taschenfederkernmatratze entweichen kann.An advantageously designed pocket spring has a circular-cylindrical or barrel-shaped basic shape, with preferably ring-shaped, if appropriate, closed top and bottom bearing surfaces which significantly reduce the pressure loads to be borne by the spring pockets. The elastic spring elements arranged between the support surfaces preferably save space from top to bottom in a space around their central longitudinal axis, so that a pocket spring mattress equipped with the inventive pocket springs is excellently ventilated and any moisture can immediately escape from the pocket spring mattress.

Eine Taschenfeder kann jedoch vorteilhafterweise auch eine Grundform mit an einer Mittelquerebene gespiegelten Kegelform aufweisen, mit entweder zur Spiegelebene ausgerichteten Kegelgrundfläche oder mit zu der Spiegelebene ausgerichteten kleineren Abschnittsfläche eines Kegelstumpfes. Sie kann gemäß einer weiteren bevorzugten Ausführungsform alternativ auch ein Federelement aus einem hohlen gummielastischen Federbalg aufweisen, mit einer geschlossenen oder mit Durchbrechungen versehenen Mantelfläche.However, a pocket spring can advantageously also have a basic shape with a conical shape mirrored on a central transverse plane, with either a conical base surface oriented towards the mirror plane or with a smaller section surface of a truncated cone oriented towards the mirror plane. According to a further preferred embodiment, it can alternatively also have a spring element made of a hollow rubber-elastic bellows, with a closed or perforated jacket surface.

Bei als kreiszylindrisch ausgebildeten Taschenfedern sind die oberen und unteren Auflagerflächen so groß ausgebildet und die Federelemente so einfedern könnend gestaltet, dass sie in jedem ein- und ausgefederten Zustand hinter der Kontur der Auflagerflächen zurückstehen, sodass keine gegenseitige mechanische Belastung der einzelnen Taschenfedern benachbarter Zeilen erzeugt wird. Wenn dies jedoch unbeachtlich oder sogar gewünscht ist, sind vorteilhafterweise natürlich auch Tonnentaschenfedern in jeder beliebigen Ausführungsform einsetzbar.In the case of pocket springs designed as circular cylindrical, the upper and lower bearing surfaces are designed to be so large and the spring elements can be deflected so that they stand behind the contour of the bearing surfaces in any compressed and rebounded state, so that no mutual mechanical stress on the individual pocket springs of adjacent rows is generated . However, if this is irrelevant or even desired, barrel pocket springs can of course also be used in any desired embodiment.

Bevorzugterweise ist in jeder Federtasche eine separate Taschenfeder angeordnet, es können jedoch auch zwei oder mehr separate Taschenfedern frei oder gegenseitig miteinander verkoppelt übereinander in einer Federtasche angeordnet sein, sodass sich die Höhe einer damit zu konstruierenden Taschenfederkernmatratze beliebig anpassen lässt.A separate pocket spring is preferably arranged in each spring pocket, but it is also possible for two or more separate pocket springs to be free or mutually coupled one above the other in one Pencil case can be arranged so that the height of a pocket spring mattress to be constructed with it can be adjusted as desired.

Erfindungsgemäß sind die Federtaschen mittig ihrer Höhe mit ein- oder beidseitig umlaufenden Distanzringen ausgestattet sind, die bevorzugt aus dem Material der Federtaschen selbst hergestellt sind, wobei die Federtaschen benachbarter Reihen im gegenseitigen Kontaktbereich entweder zwischen Federtasche und Distanzring oder zwischen zwei Distanzringen miteinander verklebt sind. Solche Distanzringe dienen zum einen der Aufrechterhaltung einer ausreichenden Flexibilität der Taschenfederkernmatratze und zum anderen der Verstärkung der Federtaschen im gegenseitigen Kontaktbereich, sodass sie in diesem nicht mechanisch geschwächt sind.According to the invention, the spring pockets are provided in the middle of their height with circumferential spacer rings on one or both sides, which are preferably made from the material of the spring pockets themselves, the spring pockets of adjacent rows being glued to one another either in the mutual contact area between the spring pocket and the spacer ring or between two spacer rings. Such spacer rings serve on the one hand to maintain sufficient flexibility of the pocket spring mattress and on the other hand to reinforce the spring pockets in the mutual contact area, so that they are not mechanically weakened in this.

Zur Aufrechterhaltung der Flexibilität der Taschenfederkernmatratze kann zusätzlich zwischen den Distanzringen und den Federtaschen ein Luftspalt aufrechterhalten sein, ebenso wie die Federtaschen einer Reihe von Federtaschen in unterschiedlichen Abständen zueinander angeordnet sein können, in dem die Nahtbereiche dazwischen unterschiedlich breit ausgeführt sind.To maintain the flexibility of the pocket spring mattress, an air gap can additionally be maintained between the spacer rings and the spring pockets, just as the spring pockets of a row of spring pockets can be arranged at different distances from one another, in which the seam regions are made with different widths in between.

Die Taschenfederkernmatratze 5 besteht aus mehreren Federkernmodulen 11, wie sie in den Figuren 9 und 10 dargestellt sind, wobei diese seitlich mit Schaumstofflängs- und -querriegeln 13;14 umgeben sind, ebenso wie mit zeichnerisch nicht dargestellten oberen und unteren Abdeckungen.The pocket spring mattress 5 consists of several spring core modules 11, as in the Figures 9 and 10th are shown, these being laterally surrounded with longitudinal and transverse foam bars 13, 14, as well as with upper and lower covers, not shown in the drawing.

Ein einzelnes Federmattenmodul 11, wie es in Fig. 9 dargestellt ist, besteht aus mehreren Reihen 2 und Zeilen 3 von Federtaschen 4, wobei die benachbarten Federtaschen 4 nebeneinander angeordneter Reihen 2 in ihren Kontaktbereichen durch ein Heißverkleben miteinander verbunden sind. Die einzelnen Reihen 2 bestehen aus einem durchgehenden Vliesmaterial, welches um die einzelnen Taschenfedern 1 herumgelegt und verschweißt ist, wobei die Taschenfedern 1 in den Federtaschen 4 unter Vorspannung gehalten sind und zwischen den einzelnen Federtaschen 4 Nahtbereiche 10 vorhanden sind.A single spring mat module 11, as in Fig. 9 is shown, consists of several rows 2 and rows 3 of spring pockets 4, the adjacent spring pockets 4 rows 2 arranged side by side are connected to each other in their contact areas by hot gluing. The individual rows 2 consist of a continuous non-woven material, which is placed around the individual pocket springs 1 and welded, the pocket springs 1 in the spring pockets 4 under tension are held and 4 seam regions 10 are present between the individual spring pockets.

Die Taschenfedern 1 bestehen aus Kunststoff und sind in einer Kunststoffspritzgussform hergestellt, wobei sie eine unteren und eine obere ringförmige Auflagerfläche 6 aufweisen und dazwischen angeordnete Federelemente 7, sowie einen um ihre Mittelsenkrechte herum erzeugten Freiraum 8, wobei insbesondere Taschenfedern 1 verwendet werden, wie sie in der DE 20 2015 102 184 U1 beschreiben sind.The pocket springs 1 are made of plastic and are manufactured in a plastic injection mold, whereby they have a lower and an upper ring-shaped support surface 6 and spring elements 7 arranged between them, as well as a free space 8 created around their central perpendicular, whereby pocket springs 1 in particular are used, as shown in FIG the DE 20 2015 102 184 U1 are described.

Die Federtaschen 4 sind entweder im Nahtbereich 10 zwischen den einzelnen Taschenfedern 1 miteinander verschweißt oder sie sind zusätzlich, etwa in ihrem mittleren Bereich, mit einem entweder einseitig oder beidseitig umlaufenden Distanzring 9 versehen, wobei die Distanzringe 9 benachbarter Reihen 2 von Federtaschen 4 oder bei nur halbseitig von Distanzringen 9 umgebenen Federtaschen 4 mittlere Bereiche dieser Federtaschen 4 und die Distanzringe 9 miteinander verklebt sind, sodass insgesamt die Federtaschen 4 eines Federmattenmoduls 11 in einem vorbestimmten Abstand zueinander angeordnet sind und noch eine leichte Verformung einer daraus hergestellten Taschenfederkernmatratze möglich ist, ohne dass die einzelnen Taschenfedern 1 oder Federtaschen 4 sich gegenseitig behindern.The spring pockets 4 are either welded to one another in the seam region 10 between the individual pocket springs 1 or they are additionally provided, for example in their central region, with a spacer ring 9 which runs either on one side or on both sides, the spacer rings 9 of adjacent rows 2 of spring pockets 4 or with only spring pockets 4 surrounded on one side by spacer rings 9, middle regions of these spring pockets 4 and the spacer rings 9 are glued to one another, so that overall the spring pockets 4 of a spring mat module 11 are arranged at a predetermined distance from one another and a slight deformation of a pocket spring mattress made therefrom is still possible without the individual pocket springs 1 or spring pockets 4 hinder each other.

Eine tonnenförmige Ausbildung der Taschenfedern 1 zur Erzeugung einer Tonnentaschenfederkernmatratze ist hier ebenfalls denkbar, wodurch der Effekt der Distanzringe 9 weiter verstärkt wird.A barrel-shaped design of the pocket springs 1 to produce a barrel pocket spring mattress is also conceivable here, whereby the effect of the spacer rings 9 is further enhanced.
