Abstract

An emergency exit monitor system for school buses provides both an audible and visual signal to the driver when one of the emergency exits is opened. The school bus comprises a plurality of emergency exits. One or more sensors detect when an emergency exit is open. A monitor communicates with the sensors and provides a visual and audible signal to the driver when a sensor detects an emergency exit is open. In one embodiment, the monitor additionally identifies which of the emergency exits are open.

Claims

1. An emergency exit monitor system for a school bus having a roof, forward and rearward ends, left and right sides, a passenger door, a driver'"'"'s seat and a plurality of passenger seats, a first emergency exit located on the rearward end of the bus, said first emergency exit having an open position and a closed position and being operable for evacuating school bus passengers in the event of an emergency, a second emergency exit on the left side of the bus, said second emergency exit having an open position and a closed position and being operable for evacuating school bus passengers in the event of an emergency, and a third emergency exit on the right side of the bus, said third emergency exit having an open position and a closed position and being operable for evacuating school bus passengers in the event of an emergency, the system comprising:

(a) at least one sensor monitoring each of the emergency exits, each of said sensors being operable for detecting when the corresponding emergency exit is in the open position;

(b) a monitor in communication with the sensors, the monitor having individual indicators each corresponding to an emergency exit for providing a visual signal to the driver when a sensor detects that the corresponding emergency exit is in the open position; and

(c) an audible alarm in communication with the monitor and being operable to sound when a sensor detects that one of the emergency exits is in the open position.

2. The system according to claim 1, wherein the emergency exits are selected from a group consisting of an emergency exit door, emergency exit window, emergency exit hatch, and emergency exit panel.

3. The system according to claim 1, further comprising a fourth emergency exit on the roof of the bus, said fourth emergency having an open position and a closed position and being operable for evacuating school bus passengers in the event of an emergency.

4. The system according to claim 1, wherein the indicators are positioned in a location which can be seen conveniently by the driver while seated in the driver'"'"'s seat.

5. The system according to claim 1, wherein the monitor comprises a visual representation of the school bus and the indicators are positioned relative to the representation of the school bus to indicate the corresponding emergency exit.

6. The system of claim 5, wherein the indicators are light emitting diodes.

7. The system according to claim 1, wherein each indicator is labeled with text describing the corresponding emergency exit.

8. The system according to claim 1, further comprising an electrical circuit interconnecting the sensors, monitor and audible alarm.

9. The system according to claim 8, wherein the electrical circuit is arranged to effect an armed state and a disarmed state.

10. The system according to claim 9, wherein the circuit is in the armed state when the ignition is in the on position and the circuit is in the disarmed state when the ignition is in the off position.

11. The system according to claim 8, wherein at least a portion of the electrical circuit is a microprocessor.

12. The system according to claim 1, wherein the audible alarm comprise a buzzer.

13. The system according to claim 1, wherein at least one of the emergency exits has a latching mechanism.

14. An emergency exit alarm system for a school bus having a roof, forward and rearward ends, left and right sides, a passenger door, a driver'"'"'s seat and a plurality of passenger seats, the system comprising:

(a) a plurality of emergency exits each having an open position and a closed position and being operable for evacuating school bus passengers in the event of an emergency, said emergency exits comprising;

i) a rear emergency exit located on the rearward end of the bus;

ii) a left emergency exit on the left side of the bus;

iii) a right emergency exit on the right side of the bus; and

iv) a roof emergency exit on the roof of the bus;

(b) at least one sensor monitoring each of said emergency exits and being operable for detecting the position of each of the emergency exits;

(c) a monitor in communication with the sensors, the monitor having individual indicators each corresponding to an emergency exit and being operable to provide a visual signal to the driver when a sensor detects that an emergency exit is in the open position;

(d) an audible alarm operable to alert the driver when one of the emergency exits is opened;

(e) a power source; and

(f) an electrical circuit electrically interconnecting the sensor, monitor, audible alarm, and power source and arranged to effect an armed state in which the alarm system is activated, and a disarmed state in which the alarm system is deactivate.

15. The system according to claim 14, wherein the emergency exits are selected from a group consisting of an emergency exit door, emergency exit window, emergency exit hatch, and emergency exit panel.

16. The system according to claim 14, wherein the school bus further comprises one or more additional emergency exits that do not have corresponding sensors.

17. The system according to claim 14, wherein each indicator is labeled with text describing the corresponding emergency exit.

18. The system according to claim 14, wherein the monitor comprises a visual representation of the school bus and the indicators are positioned relative to the representation of the school bus to indicate the corresponding emergency exit.

19. An emergency exit alarm system for a school bus having a roof, forward and rearward ends, left and right sides, a passenger door, a driver'"'"'s seat and a plurality of passenger seats, the system comprising:

(a) a first emergency exit means for evacuating school bus passengers out of the rear of the bus in the event of an emergency;

(b) a second emergency exit means for evacuating school bus passengers out of the left side of the bus in the event of an emergency;

(c) a third emergency exit means for evacuating school bus passengers out of the right side of the bus in the event of an emergency;

(d) a means for detecting when one or more of the emergency exit means are open;

(e) a means for visually indicating which emergency exit means is open, said indicating means being in communication with the detecting means; and

(f) a means for audibly signaling when at least one emergency exit means is open.
