Abstract
An illuminating circuit for the key slot in a locking device is made up of a high intensity light source which is mounted on the face plate of the lock in close proximity to the key slot, a piezoelectric crystal is mounted within or adjacent to the lock to respond to vibrations created, for example, by tapping on the face plate to generate an electrical signal, and a control circuit including a timer and battery respond to the electrical signal generated by the crystal to energize a light source for a predetermined time interval after receiving the electrical signal from the crystal.
Claims10
In a door locking device for an entry way in which a locking mechanism extends through an opening in the entry way including a face plate on an exterior surface of said entry way and a key slot therein for insertion of a key to actuate said locking mechanism, the improvement comprising:
- a light source mounted on said exterior surface adjacent to said key slot;
- a power source;
- motion-sensing means disposed internally of said entry way responsive to motion or vibration of said entry way to generate an electrical signal;
- and
- circuit means associated with said power source responsive to receiving said electrical signal from said motion-sensing means to energize said light source.
An illuminating circuit for a lock assembly in an entry way in which a locking mechanism extends through an opening in the entry way including a face plate on an exterior surface of said entry way and actuating means on said face plate to actuate said locking mechanism, said circuit comprising:
- a light source on said face plate;
- a portable power source;
- motion-sensing means disposed internally of said entry way and responsive to vibration of said entry way sensed to generate an electrical signal;
- and
- circuit control means associated with said power source and being responsive to said electrical signal generated by said motion-sensing means to energize said light source.
In a door lock assembly for an entry door in which a locking mechanism extends through an opening in said door and includes a face plate on an exterior surface of said door with a key slot for insertion of a key to actuate said locking mechanism, the improvement comprising:
- a high intensity light source mounted on said face plate in close proximity to said key slot;
- a portable power source;
- circuit control means mounted in said door lock assembly including a timer circuit associated with said power source and being directly responsive to an electrical signal to energize said light source;
- and
- motion-sensing means including a piezoelectric crystal mounted in said door lock assembly responsive to vibrations sensed in said door lock assembly to generate said electrical signal and transmit same to said circuit control means.
