Frage an die Fachleute( entschuldigung, wenn dieses Thema langweilig erscheint, aber Technik begeistert mich eben):

Die Firma Montres Rolex SA ist Inhaberin eines Patentes über Stifte zur Verbindung der Glieder eines Armbands, wobei diese Stifte aus einer sogenannten Gedächtnislegierung bestehen. Diese Stifte wurden ursprünglich von Gay Frères erfunden, aber diese Firma wurde 1998 von Rolex geschluckt, pardon "eingegliedert".

Weiss möglicherweise jemand, ob solche Stifte in aktuellen Modellen Verwendung finden?

Patent Nummer ist: EP 0 870 117 B1

Wortlaut (Anspruch):
Method for fixing two elements together, in particular links of a metal wristwatch strap, according to which a metal pin made of a moulding memory alloy with large hysteresis - programmed such that it turns from the martensitic structure to the austenitic structure in a first temperature range which is situated above the service temperature of the elements and whereby its thickness increases, and such that it turns back from the austenitic structure to the martensitic structure in a second temperature range which is situated under the above-mentioned service temperature - is clamped in the martensitic structure in at least one either or not blind hole in at least one of the elements to be linked; the pin is subsequently heated to a temperature higher than the first temperature range, such that the thickness of the pin is increased, whereby the clamping force of the pin in the hole becomes very large; and the pin is finally cooled down to service temperature, characterized in that a pin with a martensitic structure is put in at least one hole having a thickness which is slightly larger than the width of the hole.
