РЕФЕРАТ (Abstract)

An ambulance cot loading and unloading apparatus includes a base for mounting to an emergency vehicle deck and an arm mounted for linear movement along the base, which is configured for engaging an ambulance cot. A drive mechanism is provided for raising the arm, which is configured in the presence of an applied force with a first magnitude on the arm to raise the arm at a first speed and in the presence of an applied force on the arm with a second magnitude greater than the first magnitude to raise the arm at another speed or speeds lower than the first speed.

ФОРМУЛА ИЗОБРЕТЕНИЯ (CLAIMS)

What is claimed is:

1. An ambulance cot and cot loading and unloading system for an emergency vehicle comprising: a cot having a cot-based control system with a cot-based user input device; a cot loading and unloading apparatus comprising: a drive mechanism; a latch for engaging said cot; and a loading and unloading apparatus-based control system, said loading and unloading apparatus-based control system configured for controlling said drive mechanism; and when said cot is loaded onto said loading and unloading apparatus said cot-based control system configured for controlling said drive mechanism and forming a primary control system for controlling said drive mechanism, and said loading and unloading apparatus-based control system becoming a slave control system to said primary control system.

2. The ambulance cot and cot loading and unloading system according to claim 1, said loading and unloading apparatus-based control system has a loading and unloading apparatus-based user input device, said loading and unloading apparatus-based user input device being configured to allow control of said drive mechanism even when said cot is loaded onto said loading and unloading apparatus to thereby provide redundant controls.

3. An ambulance cot and cot loading and unloading system for an emergency vehicle comprising: a cot having a cot-based control system and a cot-based user input device in communication with said cot-based control system; a cot loading and unloading apparatus comprising: a drive mechanism; and a loading and unloading apparatus-based control system, said loading and unloading apparatus-based control system configured for controlling said drive mechanism; and when said cot is loaded onto said loading and unloading apparatus said cot-based control system configured for controlling said drive mechanism and forming a primary control system for controlling said drive mechanism, and said loading and unloading apparatus-based control system becoming a slave control system to said primary control system wherein said cot also includes a cot-based communication system for communicating with a communication system on said loading and unloading apparatus.

4. The ambulance cot and cot loading and unloading system according to claim 3, wherein said cot-based communication system is wireless.

5. The ambulance cot and cot loading and unloading system according to claim 4, wherein said wireless communication system comprises an RF communication system.

6. The ambulance cot and cot loading and unloading system according to claim 1, wherein said cot-based control system is configured for selectively actuating said latch when said cot is loaded on to said loading and unloading system.

7. The ambulance cot and cot loading and unloading system according to claim 6, wherein said cot loading and unloading apparatus further includes a mechanism for moving said latch to engage said cot for moving said cot when said cot is loaded onto said cot loading and unloading apparatus.

8. The ambulance cot and cot loading and unloading system according to claim 7, further comprising a base for mounting to a deck of an emergency vehicle; and said latch mounted for linear movement along said base.

9. The ambulance cot and cot loading and unloading system according to claim 8, further comprising a track mounted for linear movement along said base; and said latch mounted for linear movement along said track.

10. An ambulance cot and cot loading and unloading system for an emergency vehicle comprising: a cot having a cot-based control system and a cot-based user input device in communication with said cot-based control system; a cot loading and unloading apparatus comprising: a drive mechanism; and a loading and unloading apparatus-based control system, said loading and unloading apparatus-based control system configured for controlling said drive mechanism; and when said cot is loaded onto said loading and unloading apparatus said cot-based control system configured for controlling said drive mechanism and forming a primary control system for controlling said drive mechanism, and said loading and unloading apparatus-based control system becoming a slave control system to said primary control system, wherein said cot loading and unloading apparatus includes an arm assembly for engaging said cot.

11. The ambulance cot and cot loading and unloading system according to claim 10 wherein said cot loading and unloading apparatus further includes a drive mechanism for moving said arm assembly to engage said cot.

12. The ambulance cot and cot loading and unloading system according to claim 10, further comprising a track supporting said arm assembly and mounted for linear movement along said base, wherein when said track is extended along said base and said arm assembly is extended along said track said arm assembly is extended from said base in an extended position and is configured for lifting said cot and providing cantilevered support to said cot while in said extended position.

13. The ambulance cot and cot loading and unloading system according to claim 12, wherein said arm assembly is pivotally mounted to a frame, said frame mounted for linear movement along said track.

14. The ambulance cot and cot loading and unloading system according to claim 10, wherein said arm assembly includes a pair of arms.

15. The ambulance cot and cot loading and unloading system according to claim 3, wherein said cot loading and unloading apparatus further includes a latch to engage said cot when said cot is loaded onto said cot loading and unloading apparatus.

16. The ambulance cot and cot loading and unloading system according to claim 15, wherein said cot loading and unloading apparatus further includes a mechanism for actuating said latch to engage said cot when said cot is loaded on to said cot loading and unloading apparatus.

17. The ambulance cot and cot loading and unloading system according to claim 15, further comprising a base for mounting to a deck of an emergency vehicle, and said latch mounted for linear movement along said base.

18. The ambulance cot and cot loading and unloading system according to claim 17, further comprising a track mounted for linear movement along said base, and said latch mounted for linear movement along said track.
