Definitions

  • the invention relates to a security key, in particular a motor vehicle combination key made of precious metal.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the drawing illustrates the invention in plan view of a key.
  • 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.
  • 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.
