Description

Die Erfindung geht aus von einer Taschenfederkernmatratze mit einer Vielzahl zusammenhängender, eingekapselter Schraubenfedern, wobei jeweils eine Schraubenfeder in einer geschlossenen Tasche aus Gewebe, Kunststoff o. dgl. angeordnet ist, und die geschlossenen Taschen in einer Richtung als Bänder aneinanderhängend angeordnet sowie quer zu der Richtung der Bänder durch Klebung verbunden sind. Die Erfindung läßt sich bei den verschiedensten Arten von Schraubenfedern anwenden, beispielsweise bei Zylinderfedern, Tonnenfedern oder auch bei Taillenfedern. Eine solche Taschenfederkernmatratze ist eine Federkernkonstruktion, also ein zusammenhängendes Gebilde aus gekapselten Schraubenfedern, welches ein Bauelement für eine komplette Matratze darstellt und welches durch Polster und Auflagen sowie einen Überzug entsprechend vervollständigt wird.The invention is based on a pocket spring mattress with a plurality of connected, encapsulated coil springs, wherein a coil spring is arranged in a closed pocket made of fabric, plastic or the like, and the closed pockets are arranged in a direction as bands attached to one another and transversely to the direction the tapes are connected by adhesive. The invention can be applied to a wide variety of types of coil springs, for example cylinder springs, barrel springs or even waist springs. Such a pocket spring mattress is a spring core construction, that is a coherent structure made of encapsulated coil springs, which is a component for a complete mattress and which is completed accordingly by upholstery and coverings as well as a cover.

Eine Taschenfederkernmatratze der eingangs beschriebenen Art ist aus der EU-OS 154 076 bekannt. Auch dabei werden Bänder oder Reihen aus geschlossenen Taschen gebildet, wobei in jeder Tasche eine Schraubenfeder untergebracht ist. Die Bänder oder Reihen werden quer zur Band- bzw. Reihenrichtung untereinander dadurch verbunden, daß ein Klebstoff auf eine Tangentiallinie der Tasche bzw. auf die Tangentiallinien der Taschen in der eine Reihe aufgebracht wird und die Taschen der benachbarten Reihe an der Berührlinie bzw. den Berührlinien angepreßt werden. Damit ist eine Feldanordnung der einzelnen Taschen möglich, also eine solche Anordnung, bei der die Achsen der untereinander verbundenen Taschen bzw. Schraubenfedern jeweils rechtwinklig zueinander angeordnet sind. Der Klebstoffauftrag kann in einzelnen Streifen oder auch einzelnen Punkten erfolgen und verbindet das Material der Taschen quer zur Richtung der Bänder unmittelbar untereinander. Zu diesem Zweck müssen die Taschen benachbarter Reihen aufeinandergepreßt werden und es ist eine gewisse Abbindezeit erforderlich, um die Klebeverbindung auszuhärten. Allerdings ist die Anordnung des Klebstoffauftrags nur auf einen relativ kleinen linienförmigen Bereich beschränkt, wenn z. B. zwei Reihen von Taschen mit eingekapselten Zylinderfedern aufeinandergepreßt gehalten werden. Noch kürzer in der Höhe wird dieser Bereich bei dem Einsatz von Tonnenfedern. Es ergibt sich dann ein verminderter Zusammenhalt der Federn untereinander und eine vergleichsweise geringe Maßhaltigkeit der gesamten Matratze. Außerdem ist das Anpressen des aufgetragenen Klebstoffs an den Taschen aneinander problematisch, weil das Material der Taschen zwischen den Abstützstellen an den Windungen der Schraubenfeder durchhängt bzw. sich einbauchend verformen läßt.A pocket spring mattress of the type described in the opening paragraph is known from EU-OS 154 076. Ribbons or rows of closed pockets are also formed, a coil spring being accommodated in each pocket. The tapes or rows are connected to one another transversely to the tape or row direction in that an adhesive is applied to a tangential line of the pocket or to the tangential lines of the pockets in one row and the pockets of the adjacent row at the contact line or the contact lines be pressed. A field arrangement of the individual pockets is thus possible, that is to say an arrangement in which the axes of the pockets or coil springs connected to one another are each arranged at right angles to one another. The adhesive can be applied in individual strips or even individual dots and connects the material of the pockets directly across the direction of the tapes among themselves. For this purpose, the pockets of adjacent rows must be pressed together and a certain setting time is required in order to harden the adhesive connection. However, the arrangement of the adhesive application is only limited to a relatively small linear area if, for. B. two rows of pockets with encapsulated cylinder springs are kept pressed together. This area becomes even shorter in height when using barrel springs. There is then a reduced cohesion of the springs with one another and a comparatively low dimensional accuracy of the entire mattress. In addition, pressing the applied adhesive onto the pockets against one another is problematic because the material of the pockets sags between the support points on the turns of the helical spring or can be deformed into a recess.

Die US-PS 2 805 429 zeigt eine Taschenfederkernmatratze aus einer Vielzahl zusammenhängender, eingekapselter Tonnenfedern. Um die Bänder oder Reihen der Tonnenfedern in Querrichtung miteinander zu verbinden, wird vorgeschlagen, Verbindungsfäden einzusetzen, die in Querrichtung durch die Taschen sämtlicher Bänder oder Reihen hindurchgeführt werden. Diese Fäden werden an den heraushängenden Enden auf beiden Seiten der Taschenfederkernmatratze miteinander verknotet. Die Fäden werden dabei so durch die Taschen benachbarter Reihen hindurchgeführt, daß abwechselnd ein Übergangsbereich zwischen zwei Taschen durchsetzt wird, während unmittelbar benachbart der Verbindungsfaden durch den Bewegungsraum der Schraubenfeder hindurchgreift. Es wird dort bereits als nachteilig erkannt, daß Nadeln, die die Fäden bei ihrem Durchgang durch die Matratze führen, bei Kontakt mit den Schraubenfedern abbrechen können, so daß vorgeschlagen wird, die Fäden während des Rückhubs der Nadeln durch die Taschen sämtlicher benachbarter Bänder hindurchzuziehen. Auf jeden Fall behindern die eingesetzten Fäden die freie Bewegung der Schraubenfedern. Andererseits führen fortgesetzte Bewegungen der Schraubenfedern zu einem Durchscheuern der Verbindungsfäden, wodurch der Zusammenhalt in Querrichtung verlorengeht.US Pat. No. 2,805,429 shows a pocket spring mattress made of a plurality of connected, encapsulated barrel springs. In order to connect the bands or rows of the barrel springs to one another in the transverse direction, it is proposed to use connecting threads which are passed in the transverse direction through the pockets of all the bands or rows. These threads are knotted together on the hanging ends on both sides of the pocket spring mattress. The threads are passed through the pockets of adjacent rows in such a way that a transition region between two pockets is alternately penetrated, while the connecting thread extends through the movement space of the helical spring immediately adjacent. It is already recognized as a disadvantage that needles, which guide the threads as they pass through the mattress, can break off when they come into contact with the coil springs, so that it is proposed to pull the threads through the pockets of all adjacent bands during the return stroke of the needles. In any case hinder the deployed Thread the free movement of the coil springs. On the other hand, continued movements of the coil springs lead to wear of the connecting threads, as a result of which cohesion in the transverse direction is lost.

Auch die US-PS 3 230 558 zeigt eine solche Taschenfederkernmatratze mit durchgehenden Verbindungsfäden über die gesamte Breite der Matratze. Auch dabei werden benachbarte Taschen auf dem jeweiligen durchgehenden Verbindungsfaden aufgespießt bzw.von diesem durchdrungen.US Pat. No. 3,230,558 also shows such a pocket spring mattress with continuous connecting threads over the entire width of the mattress. Here, too, adjacent pockets are impaled on or penetrated by the respective continuous connecting thread.

Der Erfindung liegt die Aufgabe zugrunde, ausgehend von einer Taschenfederkernmatratze der eingangs beschriebenen Art den Zusammenhalt der Reihen bzw. Bänder von Taschen quer zur Richtung der Bänder zu verbessern. Dabei soll auch die Herstellung vereinfacht werden und Nachteile ausgeschlossen werden, die durch die Form der jeweiligen Schraubenfedern bedingt sind.The invention is based on the object, starting from a pocket spring mattress of the type described above, to improve the cohesion of the rows or bands of pockets transverse to the direction of the bands. The production should also be simplified and disadvantages excluded, which are due to the shape of the respective coil springs.

Erfindungsgemäß wird dies bei einer Taschenfederkernmatratze der eingangs beschriebenen Art dadurch erreicht, daß parallel zu der Richtung der Bänder zwischen je zwei benachbarten Bändern eine Verbindungswand aus elastischem Material vorgesehen ist, und daß die Taschen der Bänder über je eine Verbindungswand mittelbar miteinander verklebt sind. Eine solche mittelbare Verklebung läßt sich - im Gegensatz zu einer unmittelbaren Verklebung - wesentlich sicherer durchführen, weil sich die Verbindungswand aus elastischem Material besser und intensiver an den Auftragsstellen des Klebstoffs miteinander in Kontakt bringen läßt. Außerdem kann vorteilhaft durch die Zwischenschaltung der Verbindungswände aus dem elastischen Material Einfluß auf spezielle gewünschte Eigenschaften der Matratze genommen werden. Vorteilhaft ist auch die Gefahr des Durchscheuerns oder des gegenseitigen Verhakens bei Federbruch gemindert, weil die Verbindungswände andererseits wieder dafür sorgen, daß die Schraubenfedern quer zur Richtung der Bänder nicht unmittelbar miteinander in Kontakt treten können.According to the invention, this is achieved in a pocket spring mattress of the type described in the introduction in that a connecting wall made of elastic material is provided parallel to the direction of the bands between two adjacent bands, and in that the pockets of the bands are indirectly glued to one another via a connecting wall. In contrast to direct bonding, such an indirect bonding can be carried out much more reliably because the connecting wall made of elastic material can be brought into contact with one another better and more intensively at the application points of the adhesive. In addition, the interposition of the connecting walls made of the elastic material can advantageously have an influence on specific desired properties of the mattress. The risk of chafing through or mutual interlocking in the event of spring breakage is also advantageously reduced because, on the other hand, the connecting walls again ensure that the coil springs cannot come into direct contact with one another transversely to the direction of the bands.

Die Verbindungswände sind zweckmäßig über die Höhe der Schraubenfedern in den Taschen durchgehend vorgesehen und können einen dem Umriß der Schraubenfedern angepaßten Querschnitt aufweisen. Damit ist der Klebstoffauftrag zwar immer noch nur in einem Linienbereich möglich. Dieser Bereich ist jedoch vergleichsweise erweitert, weil durch die Nachgiebigkeit der Verbindungswände ein guter Kontakt zu den Taschen der Schraubenfedern möglich wird.The connecting walls are expediently provided continuously over the height of the coil springs in the pockets and can have a cross-section adapted to the outline of the coil springs. This means that adhesive application is still only possible in one line area. However, this area has been expanded comparatively because the flexibility of the connecting walls enables good contact with the pockets of the coil springs.

Wenn die Verbindungswände in Längsrichtung unter Anpassung an zumindest einen Teil des Umfangs der Schraubenfedern profiliert ausgebildet sind, ist die Fläche, in der der Klebstoffauftrag erfolgen kann, auch in Richtung quer zur Achse der Schraubenfedern erheblich erweitert. Zudem ist die Profilierung der Verbindungswände auch insofern günstig, als jede einzelne Schraubenfeder damit zusätzlich an ihrem Platz gehalten und gesichert ist.If the connecting walls are profiled in the longitudinal direction with adaptation to at least a part of the circumference of the coil springs, the area in which the adhesive can be applied is also considerably expanded in the direction transverse to the axis of the coil springs. In addition, the profiling of the connecting walls is also advantageous in that each individual coil spring is additionally held and secured in place.

Die Verbindungswände können aus Schaumstoff bestehen, also aus geschäumtem Kunststoff, der sich im übrigen auf die gewünschte Elastizität einstellen läßt, so daß damit auch die Eigenschaften der Taschenfederkernmatratze insgesamt positiv beeinflußbar sind.The connecting walls can consist of foam, that is, of foamed plastic, which can be adjusted to the desired elasticity, so that the properties of the pocket spring mattress can be influenced positively overall.

Die Verklebung kann aus mehreren flächig verteilt angeordneten Klebepunkten bestehen. Sie kann streifenartig ausgebildet und aufgetragen werden. Hier eröffnen sich dem Fachmann verschiedene Realisierungsmöglichkeiten.The gluing can consist of several glue dots distributed over the surface. It can be designed and applied in strips. Various possibilities of realization open up for the expert here.

Das Verfahren zur Herstellung einer solchen Taschenfederkernmatratze kennzeichnet sich erfindungsgemäß dadurch, daß die Taschen der Bänder mittelbar miteinander verklebt werden, indem die Bänder jeweils mit einer Verbindungswand unmittelbar verklebt werden. Hierdurch erhöht sich zwar die Anzahl der Klebepunkte. Jeder einzelne Klebepunkt ist aber mit größerer Sicherheit und einfacher herstellbar, weil die elastische Nachgiebigkeit des Materials der Verbindungswand hierzu geschickt ausgenutzt wird.The method for producing such a pocket spring mattress is characterized according to the invention in that the pockets of the tapes are indirectly bonded to one another by the tapes being bonded directly to a connecting wall. This does increase the number of adhesive dots. However, each individual adhesive point can be manufactured with greater certainty and more simply because the elastic flexibility of the material of the connecting wall is cleverly used for this.

Es ist möglich, zuerst ein Band mit einer Verbindungswand zu verkleben, anschließend eine Unterteilung in Abschnitte aus Band und Verbindungswand folgen zu lassen und schließlich die Abschnitte miteinander gleichsinnig zu verkleben. Dies gestattet eine rationelle Fertigung. Zweckmäßig wird der Klebstoff auf das Material der Verbindungswand und nicht auf das Material der Taschen aufgetragen.It is possible to first glue a tape to a connecting wall, then to have a division into sections of tape and connecting wall and finally to glue the sections in the same direction. This allows rational production. The adhesive is expediently applied to the material of the connecting wall and not to the material of the pockets.

  • Figure 8 is a similar sectional view as Figure 7, but in a further embodiment.

In Figur 1 ist eine Ecke einer Taschenfederkernmatratze dargestellt. Jeweils abwechselnd sind Bänder 1, 2, 3, 4 aus Taschenfedern angeordnet, wobei aus Gewebe, Vliesstoff o. dgl. aneinanderhängende Taschen 5 gebildet sind, die mit einer Längsnaht 6 und jeweils Quernähten 7 voneinander abgeschlossen sind, aber aneinanderhängen. In jeder Tasche 5 ist eine Schraubenfeder 8 eingekapselt. Diese Ausbildung der Bänder 1, 2, 3, 4 usw. entspricht dem üblichen Stand der Technik.In Figure 1, a corner of a pocket spring mattress is shown. Bands 1, 2, 3, 4 made of pocket springs are alternately arranged, with pockets 5 formed from fabric, nonwoven fabric or the like, which are connected to one another by a longitudinal seam 6 and in each case transverse seams 7, but are connected to one another. A coil spring 8 is encapsulated in each pocket 5. This formation of the tapes 1, 2, 3, 4, etc. corresponds to the usual state of the art.

Zwischen benachbarten Bändern und auch am Anfang und am Ende ist jeweils eine Verbindungswand 9 aus elastischem Material, beispielsweise aus Schaumstoff, vorgesehen, wobei die Verbindungswände 9 (Figur 2) über die Höhe der Schraubenfedern 8 bzw. der Taschen 5 durchgehend vorgesehen sind. Die Breite der Verbindungswände 9 kann einen Bruchteil der Durchmesser der Schraubenfedern 8 betragen. Zwischen dem Material der Taschen 5 und den Verbindungswänden 9 sind eine Vielzahl einzelner Klebepunkte 10 gebildet, was zweckmäßig durch einen Klebstoffauftrag auf die Verbindungswände 9 geschieht, gegen die die Bänder aus Taschen 5 mit der für das Aushärten erforderlichen Zeit gehalten werden. Durch die Nachgiebigkeit des Materials der Verbindungswände 9 ist eine gute flächige Anlage im Bereich der Klebepunkte 10 vorhanden, so daß die Verbindung sicher und verläßlich im Bereich aller Klebepunkte 10 eintritt. Es versteht sich, daß bei dieser Ausbildung in etwa eine linienförmige Berührung zwischen den als Zylinderfedern ausgebildeten Schraubenfedern 8 und den Verbindungswänden 9 eintritt, so daß die Klebepunkte 10 entsprechend plaziert sein müssen. Die Verbindungswände 9 gemäß Figur 2 weisen rechteckigen Querschnitt auf, der über ihre Länge konstant durchgehend vorgesehen ist.Between adjacent bands and also at the beginning and at the end, a connecting wall 9 made of elastic material, for example of foam, is provided, the connecting walls 9 (FIG. 2) being provided continuously over the height of the coil springs 8 or the pockets 5. The width of the connecting walls 9 can be a fraction of the diameter of the coil springs 8. A large number of individual adhesive dots 10 are formed between the material of the pockets 5 and the connecting walls 9, which is expediently done by applying an adhesive to the connecting walls 9, against which the strips of pockets 5 are held with the time required for curing. Due to the resilience of the material of the connecting walls 9, there is a good flat contact in the area of the adhesive points 10, so that the connection occurs safely and reliably in the area of all the adhesive points 10. It goes without saying that with this design there is approximately a linear contact between the helical springs 8, which are designed as cylindrical springs, and the connecting walls 9, so that the adhesive dots 10 must be placed accordingly. The connecting walls 9 according to FIG. 2 have a rectangular cross section, which is provided to be constant throughout their length.

Figur 3 zeigt ein Ausführungsbeispiel, bei dem die Schraubenfedern 8 als Tonnenfedern ausgebildet sind. Auch hier besitzen die Verbindungswände 9 konstant über ihre Länge durchgehenden Querschnitt, der jedoch konkav ausgebildet ist, um auf diese Art und Weise den Bereich, in welchem die Klebepunkte 10 angeordnet werden können, zu vergrößern. Wie ersichtlich, können die Klebepunkte 10 sogar im Bereich der ersten und letzten Windung der Schraubenfedern 8 angeordnet werden, was bisher bei der unmittelbaren Verklebung der Taschen 5 von Schraubenfedern 8 als Tonnenfedern überhaupt nicht möglich war.Figure 3 shows an embodiment in which the coil springs 8 are formed as barrel springs. Here, too, the connecting walls 9 have a constant cross section over their length, but it is concave is configured to enlarge the area in which the adhesive dots 10 can be arranged in this way. As can be seen, the adhesive dots 10 can even be arranged in the region of the first and last turns of the coil springs 8, which was previously not possible at all when the pockets 5 of coil springs 8 were bonded directly as barrel springs.

Figur 4 verdeutlicht nochmals die Anordnung der Klebepunkte 10 für das Ausführungsbeispiel der Figur 3. Gemäß Figur 5 ist es natürlich auch möglich, die Verklebung auf den Mittelbereich der Tonnenfedern zu konzentrieren und hier die Klebepunkte streifenförmig, nämlich als Klebestreifen 11, aufzubringen bzw. anzuordnen.FIG. 4 again illustrates the arrangement of the adhesive dots 10 for the embodiment of FIG. 3. According to FIG. 5, it is of course also possible to concentrate the adhesive bonding on the central region of the barrel springs and to apply or arrange the adhesive dots in strips, namely as adhesive strips 11.

Die Ausführungsbeispiele der Figuren 6 bis 8 zeigen einen grundsätzlich ähnlichen Aufbau, jedoch sind hier die Verbindungswände 9 in Richtung ihrer Längserstreckung profiliert, d. h. sie weisen hier wechselnde Querschnitte auf. Auf diese Art und Weise ist eine bessere Anpassung an die Form der Schraubenfedern über einen größeren Umfangsbereich möglich und die Zone, innerhalb der die Klebepunkte 10 oder Klebestreifen 11 angeordnet werden können, wird erheblich größer, d. h. es ist eine vergleichsweise große Fläche vorhanden, innerhalb der die Klebepunkte 10 nahezu beliebig angeordnet werden können. Solche Zonen 12 sind in den Figuren 7 und 8 hervorgehoben dargestellt. Die aufgezeigte Profilierung der Verbindungswände 9 in Längsrichtung erbringt darüberhinaus gleichsam auch einen Formschluß zu den Taschen 5 bzw. den darin eingekapselten Schraubenfedern 8, so daß jede Schraubenfeder 8 nicht nur durch die Taschen 5 entsprechend gehalten und gesichert sind, sondern zusätzlich auch noch durch die Profilierung der Verbindungswände 9.The exemplary embodiments of FIGS. 6 to 8 show a fundamentally similar structure, but here the connecting walls 9 are profiled in the direction of their longitudinal extent, i.e. H. here they have changing cross-sections. In this way, a better adaptation to the shape of the coil springs is possible over a larger circumferential area and the zone within which the adhesive points 10 or adhesive strips 11 can be arranged becomes considerably larger, i. H. there is a comparatively large area within which the adhesive dots 10 can be arranged almost arbitrarily. Such zones 12 are shown highlighted in FIGS. 7 and 8. The profiling of the connecting walls 9 shown in the longitudinal direction also provides, as it were, a positive fit to the pockets 5 or the helical springs 8 encapsulated therein, so that each helical spring 8 is not only held and secured by the pockets 5, but also additionally by the profiling the connecting walls 9.

Die Taschenfederkernmatratzen der aufgezeigten Art lassen sich sehr einfach und kostengünstig herstellen. Die Klebepunkte 10 bzw. Klebestreifen 11 werden, z. B. in Form eines Heißklebers, maschinell durch Düsen einer entsprechenden Klebstoffauftragmaschine ausgetrieben und gelangen dabei auf einen endlosen Streifen der Verbindungswand 9. Anschließend wird ein endloses Band 1 aus aneinanderhängenden Taschen 5 mit gekapselten Schraubenfedern 8 aufgedrückt, bis die Verbindung und Aushärtung erfolgt ist. Dieses Doppelband wird dann in Bandabschnitte unterteilt, wobei nochmals - insbesondere auf das Material der Verbindungswand - weitere Klebepunkte 10 bzw. Klebestreifen 11 aufgebracht werden. Die Abschnitte werden dann kurzfristig zusammengehalten, bis auch hier die Aushärtung erfolgt, wobei ein guter Kontakt infolge der Nachgiebigkeit des Materials der Verbindungswände 9 erzielt wird.The pocket spring mattresses of the type shown can be produced very easily and inexpensively. The Adhesive dots 10 or adhesive strips 11 are, for. B. in the form of a hot glue, mechanically driven out by nozzles of a corresponding adhesive application machine and thereby arrive at an endless strip of the connecting wall 9. Then an endless band 1 of mutually attached pockets 5 with encapsulated coil springs 8 is pressed on until the connection and curing has taken place. This double tape is then subdivided into tape sections, further adhesive points 10 or adhesive strips 11 being applied again — in particular to the material of the connecting wall. The sections are then held together for a short time until hardening takes place here as well, a good contact being achieved as a result of the flexibility of the material of the connecting walls 9.
