Definitions

  • the invention relates to a lock cylinder for a lock, consisting of a Lock cylinder housing and a rotatably mounted cylinder core in which evaluation electronics for electronic coding of a key, a Device for transferring the coding from the key to the evaluation electronics and an electro-mechanical locking device that between the cylinder core and Lock cylinder housing acts, are arranged in the cylinder core.
  • Locking cylinders are increasingly being equipped with electronic coding. This currently affects Lock cylinders in which electronic coding is added to the mechanical coding. However, predominant or exclusive electronic coding is also conceivable.
  • One problem here is the spatial accommodation of the electro-mechanical locking mechanism, which locks the cylinder core and lock cylinder housing against one another or releases the rotary movement of the cylinder core.
  • a locking cylinder is known from WO 96/02721, in which the electro-mechanical lock is accommodated in the locking cylinder housing.
  • the asymmetrical arrangement of the key channel in particular on or near the outer circumference of the cylinder core, enables the cylinder core to be used much better for accommodating the electronics and the locking mechanism.
  • the largest space is available if the key channel - if it is not arranged on the outer circumference of the cylinder core - is, for example, close to the outer circumference and has a semicircular or polygonal shape - seen in cross section. Since the length of the key also has an influence on the available space, it is proposed to make the key and, accordingly, the key channel shorter, ie in relation to the axial length of the cylinder core, the key then uses only a smaller amount of space. This means that there is additional space available for the electronics or the locking mechanism in the rear area of the cylinder core.
