Wireless lock system
A system for securing a protected area (such as an internal compartment of a safe) by locking an operable opening (such as a door) in a closed position. The invention comprises a wireless lock system that may include an input apparatus located on the outside of the protected area that communicates wirelessly with other components of the lock system located inside the protected area. Various wireless technologies may be employed including, for example, infrared communication.
1. A lock system for securing a protected area by locking an operable opening in a closed position, the lock system comprising:
a user input apparatus mounted to a surface outside of the protected area, wherein said user input apparatus includes a keypad;
a wireless signal emitter in electrical communication with said user input apparatus;
a processor mounted in the protected area, wherein said processor activates components of the lock system in response to an input into said user input apparatus;
a wireless signal receiver in electrical communication with said processor and adapted to receive a wireless signal sent by said wireless signal emitter; and
a channel through which said wireless signal sent by said wireless signal emitter to said wireless signal receiver can pass unimpeded.
2. The lock system of claim 1 , wherein said channel extends at least partially through the operable opening.
3. The lock system of claim 2 , wherein said user input apparatus is mounted on the operable opening.
4. The lock system of claim 3 , wherein said lock system is powered by one or more batteries.
5. The lock system of claim 4 , wherein said user input apparatus includes a battery compartment.
6. The lock system of claim 5 , wherein said wireless signal sent by said wireless signal emitter is an infrared signal.
7. The lock system of claim 6 , further comprising a tubular sleeve positioned in said channel.
8. A user input apparatus for a lock system that is designed to secure a protected area by locking an operable opening in a closed position:
a body mounted to a surface of the operable opening, said surface being outside the protected area when the operable opening is in a closed position, said body covering at least a portion of an opening formed in said surface;
a user interface attached to said body, said user interface adapted to generate an unlock instruction; and
a wireless signal emitter adapted to communicate said unlock instruction to at least one additional component of the lock system by sending a wireless signal based on said unlock instruction, said wireless signal emitter mounted to said body in alignment with said opening formed in said surface such that said wireless signal passes unimpeded into said opening.
9. The user input apparatus of claim 8 , wherein said body comprises a backplate.
10. The user input apparatus of claim 9 , wherein said backplate includes an opening through which said wireless signal passes before entering into said opening formed in said surface.
11. The user input apparatus of claim 10 , wherein said wireless signal is an infrared signal.
12. The user input apparatus of claim 11 , further comprising a battery compartment.
13. The user input apparatus of claim 12 , further comprising an annular sidewall removably securable to said backplate.
14. The user input apparatus of claim 13 , wherein said battery compartment is accessed by separating said annular sidewall from said backplate.
15. A lock system for securing a protected area by locking an operable opening in a closed position, the lock system comprising:
a user input apparatus mounted to a surface outside of the protected area, said user input apparatus including a user interface for generating an unlock instruction, wherein said user interface includes a keypad;
a wireless signal emitter mounted to said user input apparatus, said wireless signal emitter adapted to communicate said unlock instruction to at least one additional component of the lock system by sending a wireless signal based on said unlock instruction;
a processor inaccessible from outside the protected area when the operable opening is closed, wherein said processor activates components of the lock system in response to said unlock instruction;
a wireless signal receiver in electrical communication with said processor and adapted to receive said wireless signal sent by said wireless signal emitter; and
a channel in alignment with said wireless signal emitter and said wireless signal receiver, said channel positioned such that said wireless signal sent by said wireless signal emitter passes unimpeded through said channel to said wireless signal receiver.
16. The lock system of claim 15 , wherein said wireless signal sent by said wireless signal emitter is an infrared signal.
17. The lock system of claim 16 , wherein said user input apparatus is mounted on the operable opening.
18. The lock system of claim 17 , wherein said lock system is powered by one or more batteries.
19. The lock system of claim 18 , wherein said user input apparatus includes a battery compartment.
20. The lock system of claim 19 , further comprising a sleeve positioned in said channel.
