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 the lock is actuated.
certain metals or metal alloys have a so-called shape memory, ie can take on a changed shape regardless of their current shape if they receive an energy supply, 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 ring 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 when the key is cold.
the continuous line of the rib indicates the state it is in when it is supplied with energy, whether from the outside, that is to say from the lock part or from the key itself, the shape memory of the metal or metal alloy from which the ribs exist, 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.
