This metal platelet component is characterized by having applied to its underside, i.e. application side, a hot-melt adhesive layer which increases the stability of the metal platelet component and simplifies its handling.

Description

Die Erfindung betrifft einen Metallplättchenverbund insbesondere zum Applizieren, bestehend aus Metallplättchen, die nebeneinander angeordnet und über Verkettungsglieder mittels durch die Verkettungsglieder hindurchgreifender Krallen verkettet sind.The invention relates to a metal plate composite, in particular for application, consisting of metal plates which are arranged next to one another and are linked by means of claws by means of claws extending through the chain links.

Ein Metallplättchenverbund der angegebenen Art ist bekannt und wird z.B. bei Schürzen und Handschuhen im Metzgerhandwerk als Schutz verwendet. Solche Metallplattchenverbunde werden auch gerne zu dekorativen Zwecken eingesetzt, beispielsweise bei der Herstellung von Taschen, Gürteln, Bekleidungsstücken und zur Applikation auf Bekleidungsstücken. Ein derartiger Metallplättchenverbund ist in der DE-OS 38 20 251.4 beschrieben, welche auf die Anmelderin zurückgeht. Die bekannten Metallplättchenverbunde bestehen im allgemeinen aus den Metallplättchen und Verkettungsgliedern. Die Metallplättchen sind umfänglich mit Stegen ausgestattet, welche in die Verkettungsglieder eingreifen. Der Verbund wird dadurch zustande gebracht, daß diese Stege auf der Unterseite der Metallplättchen so umgebogen sind, daß sie die Verkettungsglieder krallenartig umfassen.A metal plate composite of the specified type is known and is e.g. used as protection for aprons and gloves in the butcher's trade. Such metal plate composites are also often used for decorative purposes, for example in the manufacture of bags, belts, clothing and for application to clothing. Such a metal plate composite is described in DE-OS 38 20 251.4, which goes back to the applicant. The known metal platelet composites generally consist of the metal platelets and linking links. The metal plates are extensively equipped with webs which engage in the links. The bond is brought about by the fact that these webs on the underside of the metal plate are bent so that they encompass the chain links in a claw-like manner.

Metallplättchenverbunde der vorbeschriebenen Art weisen in der Anwendung erhebliche Nachteile auf, insbesondere wenn sie zu dekorativen Zwecken, beispielsweise bei der Herstellung von Taschen und Gürteln und dergleichen verwendet werden sollen. Einer dieser Nachteile ist die relativ geringe Stabilität der Verbunde, die sich insbesondere dann bemerkbar macht, wenn mechanisch stark beanspruchte Gegenstände wie Taschen und Gürtel daraus gefertigt werden. Bei starker Beanspruchung kommt es häufig vor, daß sich die Stege aufbiegen und damit die Verkettung zerstört wird. Ein weiterer Nachteil besteht in der Fertigung der Gegenstände selbst. Wenn man beispielsweise mehrere Metallplättchenverbunde unterschiedlicher Gestaltung oder Färbung zu einem größeren dekorativen Gegenstand zusammenfügen will, ist es erforderlich, die Verkettung an den Nahtstellen Zu öffnen, die einzelnen Stücke zusammenzufädeln und die Verkettung durch umbiegen der Stege erneut herzustellen. Diese Vorgehensweise ist in Anbetracht der geringen Größe der einzelnen Metallplättchen mühselig und zeitraubend und verursacht dadurch einen hohen Kostenfaktor.Metal plate composites of the type described above have considerable disadvantages in use, in particular if they are to be used for decorative purposes, for example in the manufacture of bags and belts and the like. One of these disadvantages is the relatively low stability of the composites, which is particularly noticeable when mechanically stressed objects such as bags and belts are made from them. In the case of heavy loads, it is often the case that the webs bend open and the chain is destroyed. Another disadvantage is the manufacture of the objects themselves. For example, if you combine several metal plate composites of different designs or colors into a larger one decorative object, it is necessary to open the chain at the seams, thread the individual pieces together and restore the chain by bending the webs. In view of the small size of the individual metal platelets, this procedure is tedious and time-consuming and therefore causes a high cost factor.

Es ist auch bekannt, beispielsweise aus der DE-PS 29 01 728, dekorative Elemente dadurch applizierbar zu machen, daß man auf ihrer Applikationsseite eine Schmelzklebstoffschicht aufträgt.It is also known, for example from DE-PS 29 01 728, to make decorative elements applicable in that a hot-melt adhesive layer is applied to their application side.

Aufgabe der vorliegenden Erfindung ist es daher einen Metallplättchenverbund zu schaffen, der eine verbesserte Stabilität aufweist und dennoch seine natürliche Flexibilität beibehält. Gleichzeitig sollte der neue Metallplättchenverbund in seiner Anwendung zur Herstellung dekorativer Gegenstände hinsichtlich der Handhabung vereinfacht sein, um dadurch eine größtmögliche Variationsmöglichkeit in Bezug auf die Verbindung verschiedener Metallplättchenverbund-Einheiten zu gewährleisten.It is therefore an object of the present invention to provide a composite metal plate which has improved stability and yet maintains its natural flexibility. At the same time, the handling of the new metal plate composite should be simplified in its application for the production of decorative objects, in order thereby to ensure the greatest possible variation with regard to the connection of different metal plate composite units.

Diese Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Maßnahmen gelöst.This object is achieved by the measures specified in claim 1.

Die Schmelzklebstoffschicht, welche nur im Bereich der Krallen der Metallplättchen aufgebracht ist bewirkt, daß die Stege, welche die Verkettungsglieder krallenartig umfassen, sich bei mechanischer Beanspruchung wie bei Zug oder Dehnung nicht mehr aufbiegen. Darüber hinaus bleibt die natürliche Beweglichkeit des Metallplättchenverbundes erhalten, d .h die Krallen umfassen die Verkettungsglieder, sind aber nicht mit diesen verklebt. Dadurch bleiben die einzelnen Metallplättchen gegen einander beweglich. Die Schmelzklebstoffschicht bewirkt weiter, daß der Metallplättchenverbund leichter und vielseitiger handhabbar ist. Einheiten unterschiedlicher Farbgebung, Ausgestaltung und Größe können leicht zu einem dekorativen Teil zusammengesetzt werden, indem sie auf ein Trägermaterial wie beispielsweise Stoff oder Leder aufgebügelt werden. Bedingt durch die Wärme schmilzt der Schmelzklebstoff, dringt in das Trägermaterial ein und bewirkt so nach dem Abkühlen eine stabile Verbindung zwischen Metallplättchenverbund und Trägermaterial. Das Trägermaterial selbst kann dann zu dem gewünschten dekorativen Gegenstand durch Nahen oder Kleben zusammengefügt werden. Besonders vorteilhaft in diesem Zusammenhang ist es, daß einzelne Stücke des Metallplattchenverbundes nicht mehr zusammengefädelt werden müssen, sondern einfach an einander geklebt werden können.The hot-melt adhesive layer, which is applied only in the area of the claws of the metal plates, has the effect that the webs, which comprise the chain links in the manner of claws, no longer bend under mechanical stress such as tension or expansion. In addition, the natural mobility of the metal plate composite is preserved, i.e. the claws encompass the links, but are not glued to them. As a result, the individual metal plates remain movable against each other. The hot-melt adhesive layer further has the effect that the metal-plate composite is easier and more versatile to handle. Units of different colors, designs and sizes can easily be put together to form a decorative part by ironing them onto a carrier material such as fabric or leather. The hot melt melts due to the heat and penetrates into the carrier material and thus creates a stable connection between the metal-plate composite and the carrier material after cooling. The carrier material itself can then be assembled into the desired decorative object by sewing or gluing. In this context, it is particularly advantageous that individual pieces of the metal-plate composite no longer have to be threaded together, but can simply be glued to one another.

In einer bevorgezugten Ausgestaltung des erfindungsgemäßen Metallplättchenverbundes, ist der Metallplättchenverbund jeweils nur im Bereich der Ränder mit der Schmelzklebstoffschicht beauftragt. Auch in diesem Fall können einzelne Einheiten verschiedener Metallplättchenverbunde zu einer größeren Einheit zusammengesetzt werden, indem die einzelnen Einheiten auf ein passendes Trägermaterial aufgebügelt werden. Ein besonderer Vorteil dieser Ausgestaltung liegt darin, daß die einzelnen Metallplättchenverbunde nur in ihren Randbereichen mit dem Trägermaterial verklebt sind, also nicht über die gesamte Flache. Bedingt dadurch, bleibt die natürliche Beweglichkeit des Metallplättchenverbundes und der damit verbundenen dekorative Effekt, in erhöhtem Maße erhalten.In a preferred embodiment of the metal-plate assembly according to the invention, the metal-plate assembly is only charged with the hot-melt adhesive layer in the area of the edges. In this case too, individual units of different metal-plate composites can be put together to form a larger unit by ironing the individual units onto a suitable carrier material. A particular advantage of this configuration is that the individual metal-plate composites are only bonded to the carrier material in their edge regions, that is to say not over the entire area. As a result, the natural mobility of the metal plate composite and the associated decorative effect are retained to an increased extent.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Metallplättchenverbundes weisen die Metallplättchen eine Vertiefung zur Aufnahme eines Schmucksteines auf. Als Schmucksteine kommen dabei insbesondere Halbedelsteine wie Jade, Rosenquarz, Lapislazuli, Onyx und dergleichen in Frage. So ausgestaltete Metallplättchenverbunde können dann zu besonders dekorativen Mustern zusammengesetzt werden.In a further preferred embodiment of the metal plate composite according to the invention, the metal plates have a recess for receiving a gem. In particular, semi-precious stones such as jade, rose quartz, lapis lazuli, onyx and the like are suitable as gemstones. Metal-plate composites designed in this way can then be put together to form particularly decorative patterns.

Eine besonders dekorative Ausgestaltung des erfindungsgemäßen Metallplättchenverbundes ergibt sich, wenn die Schmucksteine aus geschliffenem Glas bestehen.A particularly decorative embodiment of the metal-plate composite according to the invention is obtained if the gemstones consist of cut glass.

In einer ganz besonders vorteilhaften Ausgestaltung des Metallplättchenverbundes werden die Schmucksteine mittels eines wärmebeständigen Klebers in der Vertiefung der Metallplättchen befestigt. Dies ermöglicht ein einfaches Anbringen der Schmucksteine, wobei der Klebstoff entweder an den Schmucksteinen selbst oder in den Vertiefungen aufgebracht wird. Die Verwendung eines wärmebeständigen Klebers verhindert, daß sich die Schmucksteine beim Aufbügeln des Metallplättchenverbundes auf das Trägermaterial aus der Vertiefung lösen.In a very particularly advantageous embodiment of the metal plate composite, the gemstones are fastened in the recess of the metal plates by means of a heat-resistant adhesive. This enables the gemstones to be easily attached, the adhesive being applied either to the gemstones themselves or in the depressions. The use of a heat-resistant adhesive prevents the gemstones from detaching from the recess when the metal plate composite is ironed onto the carrier material.

Zweckmäßigerweise ist die Vertiefung kegelförmig ausgebildet, insbesondere dann, wenn die Schmucksteine wie im Fall von geschliffenen Glassteinen, einen kegelförmigen Fassungsabschnitt aufweisen. Damit wird ein weitgehend formschlüssiges Einpassen der Schucksteine in die Vertiefung ermöglicht.The depression is expediently conical, in particular when the gemstones have a conical frame section, as in the case of cut glass stones. This enables a largely form-fitting fit of the stone into the recess.

Es ist weiter vorteilhaft, daß die kegelförmige Vertiefung des Metallplättchens als Kegelstumpf mit einem Loch an der Kegelspitze ausgebildet ist. Hierdurch wird eine Ansammlung von Lack beim Lackieren der Plättchen oder von Klebstoff beim Verkleben der Schmucksteine in der Vertiefung in der Kegelspitze verhindert, was eine gute Anpassung des Fassungsabschnittes der Schmucksteine an die kegelförmige Vertiefung des Metallplättchens behindern würde.It is further advantageous that the conical recess of the metal plate is designed as a truncated cone with a hole at the cone tip. This will cause a build-up of varnish when painting the platelets or glue when gluing the gemstones in the recess in the Cone tip prevents what would hinder a good adaptation of the setting section of the gemstones to the conical recess of the metal plate.

Es ist weiter vorteilhaft die kegelförmige Vertiefung an der Kegelspitze mit einer sackförmigen Erweiterung auszubilden. Hierdurch wird ein Raum für eine Lack- oder Klebstoffansammlung geschaffen, wobei der Arbeitsgang des Durchstanzen des Metallplättchens entfallen kann und dennoch eine sichere Anpassung des Fassungsabschnittes des Schmucksteines an die kegelförmige Vertiefung des Metallplättchens gewährleistet ist. Die Metallplättchen bestehen in bevorzugter Weise aus eloxiertem Aluminium oder Messing. Auch lackiertes Metall ist dekorativ.It is further advantageous to design the conical depression on the cone tip with a sack-shaped extension. This creates a space for a paint or adhesive accumulation, whereby the work step of punching through the metal plate can be omitted and nevertheless a secure adaptation of the mounting section of the gemstone to the conical recess of the metal plate is ensured. The metal plates are preferably made of anodized aluminum or brass. Painted metal is also decorative.

Die Beschichtung des Metallplättchenverbundes mit der Schmelzklebstoffschicht kann auf unterschiedliche Art und Weise vorgenommen werden.The coating of the metal-plate composite with the hot-melt adhesive layer can be carried out in different ways.

Eine Möglichkeit besteht darin, das ansonsten fertige Band auf 120° C zu erwärmen und mit seiner Unterseite in fein abgerakeltes Schmelzkleberpulver zu tauchen. Beim Abkühlen wird dann die Schmelzklebeschicht gebildet.One possibility is to heat the otherwise finished tape to 120 ° C and dip its underside in finely scraped hot-melt adhesive powder. The melt adhesive layer is then formed on cooling.

Eine weitere Möglichkeit besteht darin, ein Bindemittel auf die Applikationsseite des ansonsten fertigen Metallplättchenverbundes aufzuwalzen. Als Bindemittel können insbesondere Epoxy-und Polyesterlacke verwendet werden. Das so präparierte Band wird dann in noch nassem Zustand in pulverisierten Schmelzkleber getaucht. Der Schmelzkleber wird dann durch Infrarotbestrahlung niedergeschmolzen. Bei dieser Beschichtungsweise wird insbesondere ermöglicht, die Schmelzklebstoffschicht nur im Bereich der Krallen der Metallplättchen aufzutragen.Another possibility is to roll a binder onto the application side of the otherwise finished composite metal plate. Epoxy and polyester paints in particular can be used as binders. The tape thus prepared is then immersed in powdered hot melt adhesive while still wet. The hot melt adhesive is then melted down by infrared radiation. With this type of coating, it is possible in particular to apply the hot-melt adhesive layer only in the area of the claws of the metal platelets.

Fig. 1 zeigt die Anordnung von Metallplättchen 5 und Verkettungsgliedern 6 zu einander und von der Unterseite, d.h. von der Applikationsseite 2. In der dargestellten Form sind die Metallplättchen 5 kreisförmig und weisen umfänglich und um 90° versetzt zueinander Stege bzw. Krallen 4 auf, welche jeweils in Verkettungsgliedern 6 eingreifen. Die Stege 4 umfassen dabei die Verkettungsglieder 6 krallenartig und sind zur Mitte der Metallplättchen 5 niedergebogen. Die Verkettungsglieder 6 sind zweckmäßigerweise ringförmig, dagegen können die Metallplättchen 5 jede Form aufweisen, die zur Ausbildung eines Netzwerkes geeignet ist. Beispielsweise kommen 6-und 8-eckige Formen in Betracht. Auch Formen, die in ihrer Extrapolation stark von der Kreisform abweichen, wie beispielsweise ovale, sind denkbar. Je nach Form muß aber dann unter Umständen die Länge der Stege 4, respektive der Durchmesser der Verkettungsglieder 6 relativ zueinander variiert werden, um eine gleichmäßige Vernetzung zu erzielen. Dieser Metallplättchenverbund ist im Bereich der umgebogenen Krallen 4 mit einer Schmelzklebstoffschicht 3 versehen. In einer besonders bevorzugten Ausführungsform ist, die Schmelzklebstoffschicht 3 nur an den Verbundrändern 9 aufgetragen.1 shows the arrangement of metal plates 5 and interlinking elements 6 with respect to one another and from the underside, ie from the application side 2. In the form shown, the metal plates 5 are circular and have webs or claws 4 offset circumferentially and at 90 ° to one another, which each engage in chain links 6. The webs 4 include the chain links 6 claw-like and are bent down to the center of the metal plate 5. The chain links 6 are expediently ring-shaped, whereas the metal plates 5 can have any shape that is suitable for forming a network. For example, hexagonal and octagonal shapes are possible. Shapes that differ greatly in their extrapolation from the circular shape, such as oval shapes, are also conceivable. Depending on the shape, the Length of the webs 4, or the diameter of the chain links 6 can be varied relative to each other in order to achieve a uniform cross-linking. This metal plate composite is provided with a hot-melt adhesive layer 3 in the region of the bent claws 4. In a particularly preferred embodiment, the hot melt adhesive layer 3 is applied only to the composite edges 9.

A transfer film 13 is applied to the top of the composite metal plate.

Diese Transferfolie 13 wird nach dem Aufbügeln des Metallplättchenverbundes von der Oberseite 14 entfernt. Sie dient zum einen der besseren Lagerung des Metallplättchenverbundes bis zum Gebrauch und zum anderen dem Schutz des Metallplättchenverbundes während des Aufbügelns.This iron-on transfer film 13 is removed from the upper side 14 after ironing on the composite metal plate. It serves on the one hand for better storage of the metal-plate composite until use and on the other hand for the protection of the metal-plate composite during ironing.

Die Schmucksteine 8 sind mittels eines wärmebeständigen Klebstoffes in der Vertiefung 7 befestigt. Als Wärmebeständige Klebstoffe können Phenoplaste, Aminoplaste, Epoxidharze, Acryl- und Alkydharze sowie ungesättigte Polyester-Harze verwendet werden.The gemstones 8 are fastened in the recess 7 by means of a heat-resistant adhesive. As heat resistant Adhesives can be used phenoplasts, aminoplasts, epoxy resins, acrylic and alkyd resins as well as unsaturated polyester resins.

In Fig. 2 kommt weiter zum Ausdruck wie die Schmelzklebstoffschicht 3 zur Erhöhung der Stabilität des Metallplättchenverbundes 1 beiträgt. Bei der Beschichtung des Metallplättchenverbundes 1 mit dem Schmelzklebstoff dringt dieser auch zwischen die Berührungsstellen der einzelnen Stege 4 (vgl. Fig. 1) ein und verklebt somit die einzelnen Stege 4, welche die Verkettungsglieder 6 krallenartig umfassen, untereinander. Ein Aufbiegen der Stege durch Zug oder Druck kann damit weitgehend verhindert werden.FIG. 2 also shows how the hot-melt adhesive layer 3 contributes to increasing the stability of the metal-plate composite 1. When coating the metal plate composite 1 with the hot-melt adhesive, it also penetrates between the contact points of the individual webs 4 (cf. FIG. 1) and thus glues the individual webs 4, which encompass the linking links 6, to one another. A bending of the webs by train or pressure can be largely prevented.

Die Figuren 3 und 4 zeigen besondere und bevorzugte Ausführungsformen der Vertiefungen 7 in den Metallplättchen 12. In Fig. 3 weist die kegelförmige Vertiefung ein Loch 12 auf. In Fig. 4 ist die kegelförmige Vertiefung 7 zur Aufnahme von Schmucksteinen 8 sackförmig erweitert. Beide Ausführungsformen verhindern, daß überschüssiger Lack- oder Klebstoff die Einpassung der Schmucksteine 8 in die Vertiefung 7 verhindern. Zusammen mit der Schmelzklebstoff 3 auf der Applikationsseite 2 wird dadurch ein äußerst stabiler Metallplättchenverbund 1 geschaffen.FIGS. 3 and 4 show special and preferred embodiments of the depressions 7 in the metal plates 12. In FIG. 3, the conical depression has a hole 12. 4, the conical recess 7 for receiving gemstones 8 is expanded in a sack shape. Both embodiments prevent excess paint or adhesive from preventing the gemstones 8 from fitting into the recess 7. Together with the hot-melt adhesive 3 on the application side 2, this creates an extremely stable metal-plate composite 1.
