Abstract

A security key made of precious metal and intended especially for motor vehicles consists completely of a gold/platinum alloy with a mass content of the two metals of 765 o/ooo and thereby acquires the bending and shearing strength necessary for practical use. <IMAGE>

Description

Die Erfindung betrifft einen Sicherheitsschlüssel, insbesondere einen Kraftfahrzeug-Kombinationsschlüssel aus Edelmetall.The invention relates to a security key, in particular a motor vehicle combination key made of precious metal.

Schlüssel aus Gold sind bekannt und auch für Kraftfahrzeuge schon vorgeschlagen worden. Sie bestehen aus einer üblichen Schmucklegierung - etwa Gold 750 = 18 K - und dienen als Zierschlüssel. Für den praktischen Gebrauch als Funktionsschlüssel sind die bekannten Goldschlüssel ihrer Weichheit wegen ungeeignet.Gold keys are known and have already been proposed for motor vehicles. They consist of a common jewelry alloy - such as gold 750 = 18 K - and serve as a decorative key. The known gold keys are unsuitable for practical use as function keys because of their softness.

Aufgabe der Erfindung ist es, den besonderen ästhetischen und psychologischen Reiz eines Goldschlüssels für einen voll funktionsfähigen Kombinationsschlüssel, namentlich einen Zünd- und Türschlüssel für Kraftfahrzeuge benutzbar zu machen.The object of the invention is to make the special aesthetic and psychological appeal of a gold key usable for a fully functional combination key, namely an ignition and door key for motor vehicles.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schlüssel vollständig aus einer Gold-Platin-Legierung mit 765 o/oo Massebestandteilen aus den beiden genannten Edelmetallen besteht. Es hat sich nämlich gezeigt, daß überraschenderweise diese als Zahngoldlegierung zur Herstellung von Kronen und Brücken bekannte Gold-Platin-Legierung in der Lage ist, den relativ hohen Biege- und Scherkräften zu widerstehen, die auf einen Schlüssel der vorgenannten Art bei seiner bestimmungsgemäßen Verwendung einwirken. Versuche haben bewiesen, daß ein erfindungsgemäß ausgebildeter Schlüssel selbst nach zehntausend Schließungen noch keine erkennbaren Abnutzungserscheinungen oder gar Verformungen zeigt. Die Vickers-Härte betrug dabei 295.This object is achieved in that the key consists entirely of a gold-platinum alloy with 765 o / oo mass components from the two noble metals mentioned. It has been shown that, surprisingly, this gold-platinum alloy, known as a dental gold alloy for the manufacture of crowns and bridges, is able to withstand the relatively high bending and shear forces which act on a key of the aforementioned type when used as intended . Experiments have shown that a key designed according to the invention does not show any visible signs of wear or deformation, even after ten thousand locking operations. The Vickers hardness was 295.

Ein unter der Bezeichnung "Degulor M Typ 4 Extrahart" im Handel befindliches Material der oben angegebenen Art enthält 70 % Gold, 6,5 % Platin, 13,5 % Silber und 10,0 % unedle Metalle.A material of the type specified above, which is commercially available under the name "Degulor M Type 4 Extra Hard", contains 70% gold, 6.5% platinum, 13.5% silver and 10.0% base metals.

Der neue Schlüssel ist vorzugsweise aus einem Griffabschnitt und einem Bartabschnitt zusammengesetzt, wobei die beiden Abschnitte integral - beispielsweise durch Gießen - hergestellt, aber auch durch nachträgliches Löten o. dgl. vereinigt sein können.The new key is preferably composed of a handle section and a beard section, the two sections being produced integrally, for example by casting, but also combined by subsequent soldering or the like.

Alternativ können der Griffabschnitt und der Bartabschnitt lösbar miteinander verbunden sein. Dies erlaubt einen Austausch des Bartabschnitts für den Fall der Beschädigung, des Schloßaustausches oder des Fahrzeugwechsels im Falle eines Kraftfahrzeugschlüssels, ohne daß der Griffabschnitt - der durch Gravur, eingesetzte Edelsteine o. dgl. zusätzlich bearbeitet worden sein kann - ebenfalls ausgetauscht werden müßte.Alternatively, the handle section and the beard section can be releasably connected to one another. This allows the beard section to be replaced in the event of damage, the lock exchange or the vehicle being changed in the case of a motor vehicle key, without the handle section - which may have been additionally worked by engraving, inserted gemstones or the like - also having to be exchanged.

Die Zeichnung veranschaulicht die Erfindung an der Draufsicht auf einen Schlüssel.The drawing illustrates the invention in plan view of a key.

Der Griffabschnitt 1 und der Bartabschnitt 2 des dargestellten Flachschlüssels (Kraftfahrzeugschlüssel) sind infolge gemeinsamen Gießens aus der Gold-Platin-Legierung integral miteinander verbunden. Der Führungsschlitz 3 und die Einschnitte 4 sind zweckmäßig durch Fräsen bzw. Schleifen hergestellt. Das Loch 5 im Griffabschnitt 1 ist entweder eingegossen oder gebohrt.The handle section 1 and the beard section 2 of the flat key (motor vehicle key) shown are integrally connected to one another as a result of joint casting from the gold-platinum alloy. The guide slot 3 and the incisions 4 are expediently made by milling or grinding. The hole 5 in the handle section 1 is either cast in or drilled.

Über das dargestellte Beispiel hinaus lassen sich auch Schlüssel anderer Konstruktion erfindungsgemäß ausbilden, beispielsweise solche, die statt der seitlichen Einschnitte flachseitige Einsenkungen für die Zuhaltungen des zugehörigen Schlosses haben, oder bei denen die die Zuhaltungen betätigenden Einrichtungen sich auf einer Platte befinden.In addition to the example shown, keys of a different construction can also be designed according to the invention, For example, those that have flat-side depressions for the tumblers of the associated lock instead of the lateral incisions, or in which the devices actuating the tumblers are located on a plate.
