Problems solved by technology

This device has the disadvantage that due to the 45° arrangement of the small tube, the locking process is only shown when the key is turned in the lock by more than 45°
Different from the technical solution of the present invention, the operation of the display device on the one hand through the small reaction force in the locking process of the lock, on the other hand the device is based on the premise of a special configuration of the key from the front, - if this is the case, so that the display device can only be retrofitted with great effort

Abstract

An apparatus indicates the closure state of a key-operated lock, having a housing that is fitted to the key and has a rotation detection sensor which is held therein and comprises a hollow body that is filled with a first electrically conductive liquid and has electrically conductive contacts for production of electrical contact sequences which are dependent on the closing direction, and having an electronic evaluation unit which uses the contact sequences to determine the closure state of the lock. The hollow body is substantially completely filled with the first electrically conductive liquid and with a second electrically non-conductive fluid that repels the first liquid.

Description

technical field [0001] The invention relates to a display device for checking the locking state of a lock. Background technique [0002] It is usually necessary in daily life that when no authorized person needs to stay in buildings, offices, houses, motor vehicles, etc., their doors should be locked to prevent unauthorized people from entering. The last person to leave the building must pay attention to whether the corresponding door is really locked, not just "closed", because a "closed" door can be opened by unauthorized people in a short time with simple means, And thus only little protection is provided. [0003] In practice, it often occurs in this respect that the relevant door is only closed and not locked, and the person concerned usually only asks after some time whether the door is really locked or only closed . As experience has shown, the problem is usually cleared up in such a way that the person will return and return to the appropriate door to check it. S...
