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.
Claims18
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.
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.
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.
