ABSTRACT:
A cover mechanism for covering a lock, having a key opening, on a lock support surface includes a cover plate which may be pivoted between a closed position in which the key opening of the lock is covered, and an opened position in which the key opening is exposed. A detent arrangement engages the cover plate at a first point to hold it in its opened position until a key is inserted into the key opening and rotated towards an unlatching position, whereupon the detent arrangement engages the cover plate at a second point and prevents movement of the cover plate into its closed position. The cover plate is released when the key is withdrawn from the lock such that the cover plate is free to move into its closed position.
