Definitions

  • the invention relates to a key for a rotary lock cylinder according to the preamble of independent claim 1.
  • Such a key has become known from DE-B-1 093 253.
  • a key which has a pin at its front end which is displaceable transversely to the key shaft.
  • the pin When the key is inserted into a key channel, the pin is pushed against a projection protruding into the key channel, which pushes the pin against an opposite tumbler.
  • the mentioned 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 displaceable pin arranged in the key can be actuated with a mandrel which is attached to the driver of the rotary lock cylinder and which 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 protrudes outwards at one end, it does not require more space on the surface of the shaft than a conventional counterbore. Two sliding 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.
  • the key 1 according to the invention shown in FIG. 1 has a shaft 1a with conventional countersunk holes 1b, which can also be attached to the narrow sides 1e.
  • 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 1d which extends in the longitudinal direction of the axis of rotation of the key 1, is incorporated into the end face 1c of the shaft 1a.
  • This channel 1d intersects with a transverse bore 1a, which opens outwards on the two narrow sides 1e of the key shaft 1a.
  • two bearing sleeves 6 are inserted, each of which is flush at its ends with the narrow sides 1e and the inner surface of the channel 1d.
  • a slidable pin 5 or 10 is slidably mounted.
  • 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 classified by the associated key 1 and thereby a rotor 3 can be rotated in a housing 2.
  • the rotational movement of the rotor 3 is transmitted to the lock bolt with a known driver 4.
  • a mandrel 4a which projects into the key channel 3c, is fastened to the otherwise customarily designed driver 4.
  • This mandrel 4a is designed such that when the key 1a is inserted into the key channel 3c, it engages in the channel 1d without resistance, as shown in FIG. 2.
  • 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 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).

Claims (8)

  2. Clef suivant la revendication 1, caractérisée en ce que la clef présente deux goupilles opposées (5, 10) qui peuvent être déplacées simultanément radialement vers l'extérieur par la broche (4a) à introduire dans le canal (1d).
  3. Clef suivant la revendication 2, caractérisée en ce que les deux goupilles opposées (5, 10) peuvent être déplacées radialement vers l'extérieur selon une course différente.
  4. Clef suivant la revendication 3, caractérisée en ce que la course différente est obtenue par enlèvement de matériau d'un côté de l'extrémité avant d'une goupille (5).
