WIPO Patent Application WO/2004/001166
Kind Code:
A1
Abstract:
The invention relates to protection against an unauthorised access, in particular to code locks and can be used for locking different objects. The inventive code lock contains a body, a latch, a code unit, an infrared source and at least one thermal power converter which is arranged in such a way that it can perform a specified action on the latch. In the preferred embodiment, said specified action on the latch is performed in the form of the displacement of the latch, thereby making it possible to fully close or open the lock. In order to perform said specified action, at least one thermal power converter is optically connected to the infrared source by means of an optical communication line passed through the code unit. In the preferred embodiment of the lock, at least one thermal power converter is arranged in such a way that it blocks the displacement of the latch and is optically connected to the infrared source. In preferred variant, said thermal power converter is embodied in the form of a bimetallic plate.
