Description

Die vorliegende Erfindung ermöglicht es nun, die erwähnten Schwierigkeiten mindestens teilweise zu beheben, indem Hornschichten auch aus kleinen leichten Hörnern zusammen mit Zwischenschichten aus Holz oder Textilmaterial 5 zu einem Schichtstoff verklebt werden. Der erfindungsgemäs-se Schichtstoff, der sich insbesondere für Brillenfassungen und Schmuckgegenstände eignet, ist in Patentanspruch 1 definiert. Ein solches Material ist viel weniger brüchig als ein ein- oder mehrschichtiges Hornmaterial. Ausserdem sind io z.B. Brillenfassungen aus dem neuen Schichtstoff den bisherigen, nur aus Horn hergestellten ein- oder mehrschichtigen Fassungen, überlegen, weil sie sich nicht, wie die letzteren, beim Lagern in unverglastem Zustand im mittleren Teil verziehen. Die neuen Fassungen können somit beliebig 15 lange gelagert werden, ohne vor dem Verglasen zuerst wieder gerichtet werden zu müssen. Dies ist für den Optiker ein wesentlicher Vorteil. The present invention now makes it possible to at least partially overcome the difficulties mentioned, by gluing horny layers, even of small, light horns, together with intermediate layers of wood or textile material 5 to form a laminate. The laminate according to the invention, which is particularly suitable for spectacle frames and jewelry, is defined in claim 1. Such a material is much less fragile than a single or multi-layer horn material. In addition, io e.g. Spectacle frames made of the new laminate are superior to the previous one-layer or multi-layer frames, which are only made from horn, because, like the latter, they do not warp in the middle part when stored in the unglazed state. The new frames can therefore be stored for as long as 15 hours without having to be straightened again before glazing. This is a major advantage for the optician.

Der neue Schichtstoff wird erhalten wie in Patentanspruch 5 definiert. Die hierzu verwendbaren Hornplatten 20 sind im Handel erhältlich oder können auf bekannte Weise hergestellt werden. Diese Platten weisen eine Dicke von nicht über 6 mm, z.B. 2 oder 3 mm auf. The new laminate is obtained as defined in claim 5. The horn plates 20 which can be used for this purpose are commercially available or can be produced in a known manner. These plates have a thickness of not more than 6 mm, e.g. 2 or 3 mm.

Die Erfindimg ermöglicht es somit, Hornschichten be-25 liebiger Dicke, im allgemeinen weit unter den bisher erforderlichen 6 mm zusammen mit Holz- oder Textilzwischen-schichten zu einem Material zu vereinen, das alle guten Eigenschaften des bisher verwendeten Naturhorns aber eine wesentlich geringere Brüchigkeit aufweist. Ausserdem lässt 30 sich das Hornmaterial besser ausnützen, weil weniger Abfall entsteht. Durch die Mitverwendung der Zwischenschicht wird nicht nur die Festigkeit des Materials erhöht, sondern auch sein Gewicht herabgesetzt. The invention thus makes it possible to combine horn layers of any thickness, generally well below the 6 mm previously required, together with wood or textile intermediate layers to form a material which, however, has all the good properties of the natural horn used to date, but has a much lower brittleness . In addition, the horn material can be better used because less waste is generated. The use of the intermediate layer not only increases the strength of the material, but also reduces its weight.

Ausserdem ermöglicht es die Erfindung, durch Kombi-35 nation von Hornschichten und Holz- bzw. Textilschichten verschiedener Färbung und/oder Zeichnung und/oder Dicke ganz neue, bisher mit Naturhorn allein unbekannte modische Effekte zu erzielen. In addition, the invention makes it possible, by combining horn layers and wood or textile layers of different colors and / or drawing and / or thickness, to achieve completely new fashionable effects that were previously unknown with natural horn alone.

Als Zwischenschicht eignen sich handelsübliche Holz-40 fourniere von nicht über 2 mm, vorzugsweise 1 mm Dicke, z.B. aus Esche, Eiche, Wurzelhölzern, Ahorn, Palisander, Mahagoni, Rosenholz, usw. Ferner können Textilien, z.B. feine Gewebe aus Seide, Baumwollen, Leinen, usw., in roher, gefärbter oder bedruckter Form als Zwischenschicht verwen-45 det werden, ebenso feine Kunstfasergewebe. As an intermediate layer, commercially available Holz-40 fourniere of not more than 2 mm, preferably 1 mm thick, e.g. from ash, oak, root woods, maple, rosewood, mahogany, rosewood, etc. Furthermore, textiles, e.g. fine fabrics made of silk, cotton, linen, etc., in raw, dyed or printed form, can be used as an intermediate layer, as can fine synthetic fiber fabrics.

Zum Verkleben der einzelnen Schichten wird im allgemeinen ein Klebstoff verwendet, der zu einer vollständig durchsichtigen Klebschicht trocknet oder härtet, so dass sie am fertigem Material von Auge überhaupt nicht wahrnehm-50 bar ist. Zur Erzielung besonderer Effekte kann jedoch auch die Klebstoffschicht gefärbt oder nicht durchsichtig sein. In general, an adhesive is used to glue the individual layers, which dries or hardens to a completely transparent adhesive layer, so that it is not perceptible to the finished material at all by 50 bar. In order to achieve special effects, however, the adhesive layer can also be colored or not transparent.

Der verwendete Klebstoff sollte dieselbe Elastizität wie die Schichtmaterialien aufweisen. Auch sollte er derart temperaturbeständig sein, dass er sich weder bei der zur Ver-55 klebung und weiteren Verarbeitung des Schichtstoffes verwendeten Wärme noch bei den im Gebrauch gelegentlich auftretenden Tieftemperaturen in irgend welcher Art verändert, sich löst, schrumpft oder dergleichen. The adhesive used should have the same elasticity as the layer materials. It should also be temperature-resistant in such a way that it does not change, dissolve, shrink or the like, either in the heat used for gluing and further processing of the laminate, or in the low temperatures that occasionally occur during use.

60 Geeignete Klebstoffe sind im Handel erhältlich und dem Fachmann bekannt. Gute Resultate werden z.B. mit Holz-klebstoffén und mit Zweikomponentenklebstoffen, wie «Araldit», erhalten. 60 Suitable adhesives are commercially available and known to the person skilled in the art. Good results are e.g. with wood adhesives and with two-component adhesives such as «Araldit».

werden auf der geschliffenen Oberfläche dünn und gleich-massig mit «Araldit rapid» bestrichen. Ein 0,8 mm dickes Eschenfoumier wird ebenfalls auf beiden Seiten mit Klebstoff versehen, die drei Schichten sodann vereint und während 2 Stunden einem Druck von 5 Tonnen ausgesetzt. are thinly and evenly coated with «Araldit rapid» on the sanded surface. A 0.8 mm thick ash foumier is also provided with adhesive on both sides, which then combines three layers and is subjected to a pressure of 5 tons for 2 hours.

Das erhaltene dreischichtige Material wird nun wie üblich zu einem Brillengestell verarbeitet, das sich beim Lagern nicht verzieht, wesentlich weniger bruchgefährdet ist als ein Artikel aus Horn allein, ausgezeichnete Trageigenschaften 5 aufweist und ästhetisch schön wirkt. The three-layer material obtained is now processed, as usual, into an eyeglass frame that does not warp when stored, is much less prone to breakage than an article made from horn alone, has excellent wearing properties 5 and is aesthetically pleasing.

Use of a laminate according to claim 1 for the manufacture of eyeglass frames, characterized in that the laminate is cut into the desired shape. 9. Brillenfassung, erhalten durch Verwendung nach Patentanspruch 8. 9. glasses frame, obtained by use according to claim 8. Brillenfassungen aus Naturhorn sind trotz ihres hohen Preises infolge ihres Tragkomfortes sehr begehrt. Im Gegensatz zu Kunststoffen aller Art bietet Naturhorn eine viel bessere Hautverträglichkeit, so dass keine Allergien auftreten, wie sie bei Kunststoff häufig anzutreffen sind. Das unangenehme starke Schwitzen unter einer Kunststoffbrillenfassung und das damit verbundene Rutschen der Brille auf der feuchten Haut fällt bei Hornbrillen weg. Eine eventuelle schwache Schweissabsonderung wird von Naturhorn sofort adsorbiert, so dass die Haftung der Fassung auf der Haut keinerlei Beeinträchtigung erfährt. Spectacle frames made of natural horn are very popular despite their high price due to their comfort. In contrast to plastics of all kinds, natural horn offers much better skin tolerance, so that there are no allergies, as are often found with plastics. The uncomfortable heavy sweating under a plastic frame and the associated slipping of the glasses on the damp skin is eliminated with horn glasses. Any weak sweat secretion is immediately adsorbed by Naturhorn, so that the adhesion of the frame to the skin is not impaired. Ferner weisen Brillen aus Naturhorn eine grosse Formbeständigkeit auf. Sie müssen, im Gegensatz zu Plastikbrillen, nicht nachgerichtet werden (Bügel). Furthermore, glasses made of natural horn have great dimensional stability. In contrast to plastic glasses, they do not have to be adjusted (temple). Bisher wurden Hornbrillenfassungen aus einem Tierhorn hergestellt, welches aufgesägt, flachgepresst, plangeschliffen und in die gewünschte Form geschnitten wurde. Hierzu dienten vor allem Büffel- und Rinderhörner von solcher Grösse, dass Hornplatten von mindestens 6 mm Dicke gewonnen werden konnten. Hörner dieser Grösse waren früher ohne grosse Schwierigkeiten erhältlich. Die heutigen Zuchtmethoden zielen jedoch darauf hin, Tiere mit möglichst kleinen und leichten Hörnern zu erhalten, die für die vorliegende Erfindung sehr geeignet sind. So far, horn-rimmed frames have been made from an animal horn, which has been sawn, pressed flat, ground flat and cut into the desired shape. Buffalo and cattle horns of such size were used for this purpose that horn plates at least 6 mm thick could be obtained. Horns of this size were previously available without great difficulty. However, today's breeding methods aim to obtain animals with horns that are as small and light as possible and that are very suitable for the present invention. Neben den eingangs erwähnten Vorteilen des Horns als Material für Brillenfassungen weist dieses Material jedoch den Nachteil einer verhältnismässig grossen Bruchgefahr auf. Ausserdem ist seine Farbe und Musterung nicht beeinflussbar, so dass es den jeweiligen Modetrends nicht angepasst werden kann. In addition to the advantages of the horn as a material for spectacle frames mentioned at the beginning, this material has the disadvantage of a relatively high risk of breakage. In addition, its color and pattern cannot be influenced, so it cannot be adapted to the respective fashion trends.
