Definitions

  • the invention relates to a lock cylinder with key according to the preamble of claim 1.
  • a locking cylinder with a key in which on the side surface or on the side surfaces of the flat key, there are provided additional longitudinal ribs which cooperate with additional locking pins, i.e. can be scanned by them.
  • a comparison in the joint between the cylinder core and the cylinder housing then enables the cylinder core to be turned further, that is to say that the lock is actuated.
  • certain metals or metal alloys have a so-called shape memory, i.e. regardless of their current shape, they can take on a different shape when they are supplied with energy, for example in the form of heat.
  • the shape memory in this case can consist in the fact that these metals or metal alloys assume a different shape compared to the shape in the cold state.
  • a thermal switch operating on this principle is known from DE-GM 79 00 875.
  • NiTi NiTi
  • the invention is based on the object, using the shape memory of such metals or metal alloys, to increase the possible variations in a locking cylinder and key and thus also to increase the reliability of such an arrangement.
  • the particular advantage of the invention can be seen in the fact that the key cannot be seen in any way as to what height is necessary for the longitudinal rib or the longitudinal rib sections which is outstanding over the side surface or side surfaces, in order to achieve a balance between the locking pins and the joint between the cylinder core and the cylinder housing to produce because the height that the corresponding rib or the rib sections have in the cold state is not identical to the height that is subsequently required.
  • the necessary amount cannot be determined by trial and error, for example by heating the key, because the energy supply that is necessary to achieve a specific change or a specific response to the shape memory cannot be applied in a targeted manner in this way.
  • the flat key itself or the part of the flat key is denoted by 1 and the key chalk is indicated by 4.
  • Longitudinal ribs or rib sections 2 and 3 protrude beyond the side surfaces of the flat key, the rib height indicated here by dash-dotted lines which they have in the cold state of the key.
  • the solid line of the rib indicates the state it is in when energized, whether from outside, i.e. For example, from the lock part or from the key itself, the shape memory of the metal or metal alloy from which the ribs are made is addressed.
  • the locking pins are designated 5 and the parting line with the reference number 6.
  • This parting line lies between the cylinder core 7 and the cylinder housing 8.
  • a further rotation of the cylinder core which compares the locking pins 5 with the Partition 6 requires, only possible if the ribs 2 and 3 have a certain height, and this height corresponds to the change in shape memory.
  • the locking pins would touch the dash-dotted line of the ribs, and thus it would be possible that after an initial rotation a tumbler pin, which is only indicated by 9, falls into the corresponding bore of the locking pins and thus prevents further rotation, which on the other hand only would be possible with a suitable key, i.e. when the rib has taken on its shape, which is outlined by the solid line.

Claims (6)

1. Cylindre de fermeture comportant une clé (1), dans lequel sont disposées dans le noyau (7) de cylindre de fermeture des broches à déclic additionnelles (5), qui explorent des surfaces directrices de la clé et qui, lorsqu'une clé convient, reposent avec leur côté frontal opposé au canal de clé en affleurement dans la ligne de joint (6) entre le noyau de cylindre (7) et le boîtier de cylindre (8), caractérisé en ce que les parties constituant les surfaces directrices (2, 3) de la clé consistent en un métal ou un alliage métallique présentant une mémoire de forme, et en ce que la hauteur nécessaire pour l'affleurement des surfaces directrices (2, 3) peut être atteinte par un apport d'énérgie qui déclenche la mémoire de forme.
2. Cylindre de fermeture comportant une clé selon la revendication 1, caractérisé en ce que la clé présente une structure de clé plate et comporte au moins une nervure longitudinale (2, 3) ou une partie de nervure longitudinale en saillie au-dessus de la (des) surface(s) latérale(s) de la clé plate en un métal ou un alliage métallique présentant une mémoire de forme.
3. Cylindre de fermeture comportant une clé selon la revendication 1, caractérisé en ce que, lorsqu'il existe plusieurs nervures ou parties de nervures longitudinales, celles-ci se composent de métaux (ou alliages métalliques) présentant une mémoire de forme différente.
4. Cylindre de fermeture comportant une clé selon l'une des revendications 1 à 3, caractérisé en ce qu'est disposé dans le noyau de cylindre un commutateur miniature qui, lors de l'introduction de la clé (1), déclenche l'amenée d'énergie.
5. Cylindre de fermeture comportant une clé selon l'une des revendications 1 à 3, caractérisé en ce que la source d'énergie qui effectue l'apport déner- gie est disposée dans l'anneau (4) de clé et en ce que l'apport d'énergie résulte d'un contact de la clé, introduite dans le noyau de cylindre, avec le cylindre.
6. Cylindre de fermeture comportant une clé selon l'une des revendications 1 à 3, caractérisé en ce que l'amenée d'énergie peut être appliquée par une unité émettrice et réceptrice disposée dans le boîtier de cylindre et dans la clé.
