DESCRIPTION:
BRIEF SUMMARY
The invention relates to a cylinder lock and key assembly for a mechanical and/or electromechanical locking having a codable locking device and means for influencing or generating electric currents.
A plurality of types of locking and switching systems are known which as a basic principle use a cylinder lock, in particular, a profile-cylinder lock. Thereby, the devices which are mounted in the cylinder lock are brought into the release position by a purely mechanical operation by means of the key bit or by the crest profile of the inserted key, or in that permanent magnets are provided on the key which correspond with permanent magnets on the devices, thus triggering the opening or locking procedure. Furthermore, devices are known, wherein contacts for a current flow or a signal transmission may be closed or opened by the bit or crest, whereby the additional profile of the key represents an improvement on the variation possibilities.
Furthermore, a locking means is known which may be actuated by means of electric switch parts, consisting of a magazine housing for receiving the switch parts, preferably reed switches which are influenced by permanent magnets provided on the key which is inserted into the magazine, thus actuating the prescribed code for actuating the locking means. Thereby, in the known device the possibility exists that the reed switch for opening or closing, as well as the permanent magnets on the key are exchangeable. In this manner the key code may be adjusted by the user himself without using special tools and without the knowledge of the code by third parties.
In the locking and switch systems which operate in accordance with current locking methods or which control the signal transmission for the electronic structure elements, a changing of the code is made impossible by third parties without the permission of the user or the use of specific tools and experts. Since the standardized dimensions for profile locking barrels contain about five or a maximum of seven devices on the key profile, it is obvious that this is not sufficient for safety devices. In the known devices, the key conduit is based on purely mechanical, electrical or electronic basis on the rotatable barrel core, and it is relatively easy to get to the locking element or the locking element coupling by boring open the key conduit immediately at the locking element coupling, so as to open the devices which are rendered immovable by the locking procedure, thus opening the container protecting the valuables.
As far as is known in single key devices the same highly developed system is used for saving the valuables, i.e., the system is used which assures the high degree of safety for a specific application, although it would not be required in other cases. Therefore, intermediary and connecting doors which are equipped with a building locking and alarm device must be equipped with the same highly developed system which renders the device very expensive. In the locking devices which are actuated by means of permanent magnets relatively voluminous and complicated housings for receiving the individual parts are required which cannot be used in normal cylinder locks without requiring an expensive reconstruction.
It is therefore an object of the invention to provide a cylinder lock with a key for a mechanical, electromechanical or electronic actuating device which can be placed into the structured installation space of a commonly known profile cylinder locking device which can be coded in a plurality of ways by the user having a high degree of safety against boring open the device, and which can be made at a reasonable price.
This object of the invention is obtained according to the invention in that a cylinder lock with a key is provided for mechanical and/or electromechanical locking having a codable locking device and means for influencing or generating electric currents. This lock has a conduit for introducing the key in the plane cross-bar of the casing of the cylinder lock which contains the lock cylinder, the key and the con
