Code type lock especially for safes. |
摘要 |
<p>The lock comprings a key (101) operated bolt and an electronic device capable of storing a code and permitting or preventing the opening of said bolt depending on the coincidence or non-coincidence of another code entered through a keyboard (1) with the previously stored code. This lock is intended to be used in a safe and presents the particularity whereby each time said safe is opened the stored code is erased and the user, on leaving it closed, is able to set a new code, which may be identical to or different from the previously stored one. This lock provides a means of dissuading undue manipulations by unauthorised persons unfamiliar with the number of the code entered, which consists in blocking the lock for a certain time when the keyboard is unduly pressed. In this case an alarm system is also provided.</p> |
