Abstract

A heavy vehicle door or ramp is opened and closed using an intuitive control system. The door includes a latch assembly, a lock assembly, and a power unit to assist in opening and closing the door. The door includes an interior joy stick handle and an exterior lever handle. From outside the vehicle, the door is opened and closed by pivoting the lever handle downwardly and upwardly, respectively. From the interior of the vehicle, the joy stick handle is pulled inwardly to close the door and pushed outwardly to open the door. Pivoting the joystick handle forwardly engages the blast locks, while pivoting the joystick handle rearwardly unlatches the latch assembly and disengages the blast locks. The power assist unit is actuated by pivotal movement of the outside door handle and lateral pivotal movement of the interior joystick handle.

Claims

1. An intuitively operated, power-assisted door mounted in a door frame, comprising:

a latch assembly moveable between latched and unlatched positions;

a lock assembly moveable between locked and unlocked position;

a power unit with opposite ends connected to the door and the door frame to move the door between open and closed positions;

a first handle to operate latch and unlatch functions of the latch assembly, lock and unlock functions of the lock assembly, and open and close functions of the power unit.

2. The door of claim 1 wherein the handle comprises a joystick.

3. The door of claim 1 wherein the handle and the door move in a first direction for opening the door and move in a second direction for closing the door.

4. The door of claim 3 wherein the handle moves in a third direction to latch and lock the door and moves in a fourth direction to unlatch and unlock the door.

5. The door of claim 3 wherein the handle moves in third and fourth directions to actuate the latch and lock assemblies.

6. The door of claim 5 wherein movement of the handle in the third and fourth directions actuates the power unit to assist in opening and closing the door.

7. The door of claim 1 further comprising a second handle on an exterior side of the door, coupled to the power unit, and pivotal so as to actuate the power unit for opening and closing the door.

8. The vehicle door of claim 7 wherein the second handle is coupled to the latch assembly and pivotal movement of the handle actuates the latch assembly from the latched to unlatched positions.

9. The vehicle door of claim 7 wherein the power unit is actuated in opposite directions by pivoting the second handle in opposite directions.

10. The vehicle door of claim 7 wherein the second handle is biased to a neutral position.

11. The door of claim 1 wherein the first handle is biased to a neutral position.

12. The door of claim 1 further comprising a shaft connected to the lock assembly and having an outer end extending outside the door, and another handle from a second similarly equipped vehicle door being mountable on the outer end of the shaft and pivotal to unlock the door for opening without actuation of the power unit.

13. The door of claim 1 wherein the first handle is on the inside of the door.

14. The door of claim 1 wherein the handle pivots forwardly to lock and latch the door.

15. The door of claim 1 wherein the handle pivots rearwardly to unlock and unlatch the door.

16. The door of claim 1 wherein the handle pivots laterally inwardly to close the door.

17. The door of claim 1 wherein the handle pivots laterally outwardly to open the door.

18. The door of claim 1 wherein the handle pivots forwardly to lock and latch the door, pivots rearwardly to unlock and unlatch the door, pivots laterally inwardly to close the door, and pivots laterally outwardly to open the door.
