Definitions

  • the invention relates to a key for a rotary lock cylinder according to the preamble of independent patent claim 1.
  • Such a key is known from US-A-4 667 495.
  • This key has a pin at its front end which is slidable across the key shaft. When the key is inserted into a key channel, the pin is pushed against a projection which projects into the key channel and pushes the pin against an opposite tumbler. By moving the pin, the mentioned tumbler is categorized.
  • recesses are required at the front end of the key on the narrow sides, but these weaken the key in this area and may make it difficult to insert the key into the key channel.
  • the recesses mentioned also restrict the available space for attaching control surfaces.
  • the invention has for its object to provide a key of the type mentioned, which avoids these disadvantages and requires the least possible structural changes to the rotary lock cylinder. The object is achieved by the invention according to claim 1.
  • the keys arranged in the displaceable pin can be actuated by a mandrel which is attached to the driver of the rotary lock cylinder 'and projects into the key channel.
  • the displacement of the above-mentioned pin is thus possible with much simpler construction measures. Since the displaceable pin only projects outwards at one end, it does not require more surface area on the surface of the shaft than a conventional counterbore. Two displaceable pins can also be attached to the key, which further improves security.
  • a major advantage of this key according to the invention is that the coded length of the pin or pins can be measured much more difficult than before. This makes copying the key even more difficult. Which further increases security for the user.
  • Fig. 2 on an enlarged scale a radial section through part of a rotary lock cylinder with inserted key shaft
  • FIG. 3 corresponds to FIG. 2, but with the key shaft fully inserted.
  • the key 1 according to the invention shown in FIG. 1 has a shaft la with conventional countersunk holes 1b, which can also be attached to the narrow sides le.
  • the key shown as an exemplary embodiment is a so-called reversible key. However, this could also be another key, for example a serrated key.
  • a channel ld is worked into the end face lc of the shaft la and extends in the longitudinal direction of the axis of rotation of the key 1.
  • This channel ld intersects with a transverse bore la which opens outwards on the two narrow sides le of the key shaft la.
  • Two bearing sleeves 6 are inserted into this bore 1a, each of which is flush at its ends with the narrow sides le and the inner surface of the channel 1d.
  • a displaceable pin 5 or 10 is slidably mounted in each bearing sleeve 6. These pins 5 and 10 are each slightly longer than the bearing sleeves 6. In the case of a reversible key, these are Pins 5 and 10 of the same length. In the case of a non-reversible key, however, these pins can have different lengths and a single displaceable pin can also suffice.
  • the key 1 is provided for a rotary lock cylinder which, according to FIGS. 2 and 3, has the usual tumblers with housing pins 2c and 3a, which are locked by the associated key
  • the pin 5 is simultaneously pushed radially outward and thereby pushes the core pin 3a radially against the force of a spring 2a in a radial bore 3b to the outside and classifies it.
  • the other tumblers not shown here are classified by the usual counterbores 1b.
  • the pin 5 is dumbbell-shaped here and is prevented from falling out of this sleeve by a constriction 6a of the bearing sleeve 6. So that the pin 5 can be inserted into the sleeve 6a, it is composed of several parts.
  • the key is a reversible key
  • two opposite pins 5 are provided according to FIG. 1, which are pushed outwards by the mandrel 4a.
  • the mandrel 4a can be designed in such a way that it moves the two opposite pins 5 outwards with a different stroke, which can increase the number of locking options. This can be achieved, for example, by removing the front end of the pin 5 on one side.

Abstract

La clé (1) possède un passage (1d) ménagé dans la face frontale (1c) du corps de la clé, dans lequel s'engage une broche (4a) située sur le poussoir (4) du cylindre de fermeture lorsqu'on introduit la clé dans le passage (3c). La broche (4a) actionne un axe (5) lors de l'engagement, lequel se trouve en position mobile dans le corps de la clé (1), radialement vers l'extérieur et intercale ainsi un axe central (3). Le corps de la clé présente, de plus, les évidements noyés habituels dans lesquels s'engagent d'autres gâchettes lors de l'introduction de la clé (1) dans le passage (3c).
