Abstract

One example embodiment is an armored vehicle door quick-release mechanism includes a handle, a slide lock latch, and an actuator mechanism. The handle is coupled to the slide lock latch. The movement of the handle in a first direction causes the slide lock latch to move in a first direction to a first position so that the slide lock latch is adapted to attach the vehicle door to the actuator mechanism adapted to open and close the vehicle door. A movement of the handle in a second direction causes that slide lock latch to move in a second direction to a second position to detach the vehicle door from the actuator mechanism.

First claim

What is claimed is:

1. An armored vehicle door quick-release mechanism comprising:
a handle;
a handle plate;
a slide lock arm;
a slide lock latch;
a slide lock guide adapted to guide a movement of the slide lock latch;
wherein the armored vehicle door quick-release mechanism is adapted to quick release an armored vehicle door on an armored military vehicle from a vehicle power system that is used to open and close the armored vehicle door on the armored military vehicle;
wherein the handle is coupled to the handle plate and the handle plate is rotatably coupled to the slide lock arm and the slide lock arm is attached to the slide lock latch, wherein a rotation of the handle in a first direction causes that slide lock latch to move in the first direction to a first position at least partially within the slide lock guide, and wherein a rotation of the handle in a second direction causes that slide lock latch to move in a second direction to a second position at least partially within the slide lock guide; and
wherein when the slide lock latch is in the first position the armored vehicle door quick-release mechanism is adapted to couple the armored vehicle door on the armored military vehicle to the vehicle power system in a locked position that prevents manual opening and closing of the armored vehicle door on the armored military vehicle, and wherein when the slide lock latch is in the second position the armored vehicle door quick-release mechanism is uncoupled from the armored vehicle door on the armored military vehicle to allow manual opening and closing of the armored vehicle door on the armored military vehicle without the armored vehicle door coupled to the vehicle power system.

2. The armored vehicle door quick-release mechanism of claim 1 further comprising:
a latch plate adapted to be moved by the vehicle power system, and wherein in the locked position the slide lock latch and the latch plate adjacently overlap.

3. The armored vehicle door quick-release mechanism of claim 2 further comprising
a door plate that is generally planer and adapted to be mounted to the armored vehicle door of the armored military vehicle, and wherein the slide lock guide is mounted to the door plate.

4. The armored vehicle door quick-release mechanism of claim 2 further comprising:
an actuator coupled to the vehicle power system and adapted to move the latch plate.

5. The armored vehicle door quick-release mechanism of claim 4 further comprising:
a rotating bracket plate assembly pivotally attached to the actuator, and wherein the rotating bracket plate assembly rotatably moves the latch plate.

6. The armored vehicle door quick-release mechanism of claim 5 wherein the door plate further comprises:
a pair of flanges extending outward from a base of the door plate; and
a pivot point passing through the flanges and the rotating bracket plate assembly, wherein the rotating bracket plate assembly rotates at the pivot point with respect to the door plate.

7. The armored vehicle door quick-release mechanism of claim 2 wherein the door plate further comprises:
a generally rectangular shaped opening, and wherein when in the locked position the latch plate is at least partially within the opening.

8. The armored vehicle door quick-release mechanism of claim 3 further comprising:
a spring adapted to bias the slide lock latch toward the locked position.

9. The armored vehicle door quick-release mechanism of claim 1 wherein the slide lock latch further comprises:
a beveled front end adapted to allow the latch plate to push the slide lock latch away from the latch plate to allow the latch plate to slip beneath the slide lock latch to create and overlap between the slide lock latch and the latch plate.

10. The armored vehicle door quick-release mechanism of claim 1 further comprising:
a hydraulic actuator coupled to the vehicle power system and adapted to move the latch plate.

11. The armored vehicle door quick-release mechanism of claim 1 further wherein the handle is an inside handle and further comprising:
an outside handle outside the armored vehicle door coupled to the inside handle wherein both the inside handle and the outside handle are coupled to the handle plate.

12. The armored vehicle door quick-release mechanism of claim 1 wherein the armored military vehicle is at least one of the group consisting of: an Abrams tank, a Bradley fighting vehicle, a Stryker vehicle, an armored personnel carrier, a high mobility multipurpose wheeled vehicle (Hummvee), a light armored vehicle (LAV), a combat support vehicle, a mine-protected vehicle, a utility vehicle, a Mine Resistant Ambush Protected (MRAP) vehicle, and a truck.

13. An armored vehicle door quick-release mechanism comprising:
a handle;
a slide lock latch;
an actuator mechanism; and
wherein the handle is coupled to the slide lock latch, wherein movement of the handle in a first direction causes that slide lock latch to move in a first direction to a first position so that the slide lock latch is adapted to attach an armored vehicle door to the actuator mechanism adapted to open and close the vehicle door, and wherein a movement of the handle in a second direction causes that slide lock latch to move in a second direction to a second position to detach the armored vehicle door from the actuator mechanism.

14. The armored vehicle door quick-release mechanism of claim 13 wherein the actuator mechanism further comprising:
an actuator; and
a rotating bracket plate assembly rotatably attached to the actuator, wherein in the first position the slide lock latch is engaged with the rotating bracket plate assembly, and wherein in the second position the slide lock latch is detached from the rotating bracket plate assembly.

15. The armored vehicle door quick-release mechanism of claim 13 further comprising:
a door mount assembly adapted to be mounted to the armored vehicle door, wherein the door mount assembly further comprises:
at least one outward extending flange, wherein the rotating bracket plate assembly is rotatably mounted to the at least one flange, and wherein the rotating bracket plate assembly further comprises:
a bracket plate adapted to be rotated by the rotating bracket plate assembly, wherein in the first position the slide lock latch overlaps the bracket plate, and wherein in the second position the bracket plate and the slide lock latch do not overlap.

16. The armored vehicle door quick-release mechanism of claim 14 wherein the rotating bracket rotates in a path of movement to open the armored vehicle door when the actuator is powered and, wherein the rotating bracket rotates in the same path of movement to open the armored vehicle door when the actuator is not powered.

17. The armored vehicle door quick-release mechanism of claim 13 further comprising:
a spring adapted to bias the slide lock latch toward the first position.

18. A method of quick-releasing an armored vehicle door from an actuator comprising moving a slide lock latch into a first position so that the slide lock latch is adapted to lock the armored vehicle door to a rotating bracket plate assembly in a locked position, wherein in the locked position the slide lock latch overlaps a bracket plate of the rotating bracket plate assembly;
moving the rotating bracket plate assembly to the locked position with the slide lock latch overlapping the bracket plate;
contracting the actuator, when the slide lock latch is in the first position and is in the locked position, to rotate the rotating bracket plat
