Abstract

Power outlets adapted for installation within an enclosure are provided. Power outlets are provided having a safety interlock adapted to prevent the creation of a hazardous condition within the enclosure as a result of the continued operation of an electrical device within the enclosed space. The safety interlock may include current limiting circuitry and hardware, hazard sensing devices interconnected with such current limiting circuitry and hardware or other circuit breaker switches, and combinations of such safety interlocks.

Claims (43)

1. A safety interlock power outlet assembly comprising:

at least one power outlet;

a positional interlock;

at least one safety interlock; and

at least one sensor capable of detecting at least one hazardous condition within an environment;

wherein the at least one safety interlock is configured to prevent a flow of electrical current between an at least one power source and the at least one power outlet upon detection of the at least one hazardous conditions;

wherein the positional interlock is configured to detect the position of the power outlet assembly relative to a specified point external to the power outlet assembly; and

wherein the safety interlock and outlet are collocated within a single standard junction box.

2. The power outlet assembly of claim 1 wherein the at least one sensor is selected from the group consisting of a smoke detector, heat detector, and toxic gas monitor.

3. The power outlet assembly of claim 2 , wherein the heat detector comprises a thermostat.

4. The power outlet assembly of claim 1 , wherein the power outlet assembly comprises at least two safety interlocks.

5. The power outlet assembly of claim 1 , further comprising a current limiting safety interlock adapted to prevent the flow of current above a specified amperage from the power source to the power outlet.

6. The power outlet assembly of claim 1 , further comprising a transformer in electrical connection with the power source and adapted to convert the incoming electrical current from AC to DC.

7. The power outlet assembly of claim 1 , further comprising a transmitter in signal communication with the at least one safety interlock for communicating the status of the power outlet assembly to a user.

8. The power outlet assembly of claim 7 , wherein the transmitter is configured to automatically transmit upon activation of any one of the at least one safety interlocks.

9. The power outlet assemble of claim 1 , wherein the single standard junction box is one of either single gang or dual gang.

10. The power outlet assembly of claim 1 , wherein the single standard junction box is one of either single gang or dual gang.

11. The power outlet assembly of claim 1 , wherein the outlet assembly further comprises a hazard connector, and wherein the sensor is located external to the junction box and is configured to be interconnected to at least one safety interlock through the hazard connector.

12. A power equipped enclosure comprising:

an enclosure defining an internal volume, said internal volume being accessible;

at least one power outlet disposed within the internal volume of the enclosure;

at least one safety interlock;

a positional interlock; and

at least one sensor capable of detecting at least one hazardous condition within an environment of the enclosure;

wherein the at least one safety interlock is configured to prevent a flow of electrical current between an at least one power source and the at least one power outlet upon detection of one or more of the at least one hazardous condition;

wherein the positional interlock is configured to detect the position of the power outlet assembly relative to a specified point external to the power outlet assembly; and

wherein the safety interlock and outlet are disposed within a single standard junction box.

13. The power equipped enclosure of claim 12 , wherein the at least one sensor is selected from the group consisting of a smoke detector, heat detector, and toxic gas monitor.

14. The power equipped enclosure of claim 13 , wherein the heat detector comprises a thermostat.

15. The power equipped enclosure of claim 12 , wherein the power outlet assembly comprises at least two safety interlocks.

16. The power equipped enclosure of claim 12 , further comprising a current limiting safety interlock adapted to prevent the flow of current above a specified amperage from the power source to the power outlet.

17. The power equipped enclosure of claim 12 , further comprising a transformer in electrical connection with the power source and adapted to convert the incoming electrical current from AC to DC.

18. The power equipped enclosure of claim 12 , further comprising a transmitter in signal communication with the at least one safety interlock for communicating the status of the power outlet assembly to a user.

19. The power equipped enclosure of claim 18 , wherein the transmitter is configured to automatically transmit upon activation of any one of the at least one safety interlocks.

20. The power equipped enclosure of claim 12 , wherein the single standard junction box is one of either single gang or dual gang.

21. The power equipped enclosure of claim 12 , wherein the specified point is disposed on a movable portion of the enclosure.

22. The power outlet assembly of claim 12 , wherein the outlet assembly further comprises a hazard connector, and wherein the sensor is located external to the junction box and is configured to be interconnected to at least one safety interlock through the hazard connector.

23. A safety interlock power outlet assembly comprising:

at least one power outlet;

at least one hazard sensor capable of detecting at least one hazardous condition within an environment;

at least one safety interlock configured to prevent the flow of electrical current between an at least one power source and the at least one power outlet upon detection of the at least one hazardous condition; and

at least one hazard connector;

wherein the at least one safety interlock and outlet are collocated within a junction box and the hazard sensor is located external to the junction box and is configured to be interconnected to the at least one safety interlock through the hazard connector.
