Abstract

A door hinge has a bottom bracket and a bottom bracket mounting rib extends from the bottom bracket. A piston has a piston housing and a piston extension connecting in telescopic connection to the piston housing. The piston housing is connected to the bottom bracket at a bottom bracket mounting rib ball joint. The door bracket extension extends from the door bracket. A connection between the door bracket extension and the piston connector is a door bracket extension ball joint. An intermediate connector is connected to the door bracket at an intermediate door bracket joint, wherein the intermediate door bracket joint is a swivel joint. The top bracket is connected to the intermediate connector at a top bracket axle.

Claims

1. A door hinge comprising:

a. a bottom bracket for securing to a vehicle frame at a lower portion of a door hinge mounting;

b. a bottom bracket mounting rib extending from the bottom bracket;

c. a piston, wherein the piston has a piston housing and a piston extension connecting in telescopic connection to the piston housing, wherein the piston housing is connected to the bottom bracket at a bottom bracket mounting rib ball joint;

d. a piston connector, wherein the piston connector is connected to the piston extension at a tip of the piston extension;

e. a door bracket for mounting to a vehicle door, wherein the door bracket is connected to the piston connector at a door bracket extension, wherein the door bracket extension extends from the door bracket, wherein a connection between the door bracket extension and the piston connector is a door bracket extension ball joint;

f. an intermediate connector, wherein the intermediate connector is connected to the door bracket at an intermediate door bracket joint, wherein the intermediate door bracket joint is a swivel joint; and

g. a top bracket for securing to a vehicle frame above the bottom bracket, wherein the top bracket is connected to the intermediate connector at a top bracket axle.

2. The door hinge of claim 1, further comprising:

a. a bottom bracket top bolt mount formed as a slot; and

b. a bottom bracket bottom bolt mount formed as a slot, wherein the bottom bracket top bolt mount and bottom bracket bottom bolt mount are formed on the bottom bracket, wherein the bottom bracket mounting rib is rigidly connected to the bottom bracket between the bottom bracket top bolt mount and bottom bracket bottom bolt mount.

3. The door hinge of claim 1, further comprising:

a. a piston base extending from the piston housing, wherein the piston base extends through the bottom bracket mounting rib; and

b. a piston base retainer securing the piston base to the bottom bracket mounting rib.

4. The door hinge of claim 3, further comprising:

a. a piston extension threading disposed on a tip of the piston extension;

b. wherein the piston connector tip is bent at an angle approximately normal to the piston connector.

5. The door hinge of claim 1, further comprising:

a. a door bracket flat face formed on the door bracket;

b. a door bracket top bolt mount; and

c. a door bracket bottom bolt mount, wherein the door bracket flat face is between the door bracket top bolt mount and the door bracket bottom bolt mount.

6. The door hinge of claim 5, further comprising:

a. a door bracket platform protruding from the door bracket flat face;

b. a wedge shaped tip disposed on the door bracket platform.

7. The door hinge of claim 1, further comprising:

a. a top bracket platform formed on the top bracket;

b. an intermediate connector first stopper disposed on the intermediate connector, wherein the intermediate connector first stopper abuts the top bracket platform; and

c. an intermediate connector second stopper disposed on an intermediate connector protrusion.

8. The door hinge of claim 7, further comprising:

a. an inside portion of the intermediate connector, wherein the intermediate connector first stopper is disposed on the inside portion of the intermediate connector; and

b. an outside portion of the intermediate connector, wherein the intermediate connector protrusion extends from the outside portion of the intermediate connector.

9. The door hinge of claim 8, further comprising:

a. a first stopper axis of rotation; and

b. a second stopper axis of rotation, wherein the first stopper axis of rotation is approximately perpendicular to the second stopper axis of rotation.

10. A door hinge comprising:

a. a bottom bracket for securing to a vehicle frame at a lower portion of a door hinge mounting;

b. a bottom bracket mounting rib extending from the bottom bracket at a bottom bracket mounting rib angle, wherein the bottom bracket mounting rib angle is approximately perpendicular to the bottom bracket;

c. a piston, wherein the piston has a piston housing and a piston extension connecting in telescopic connection to the piston housing, wherein the piston is connected to the bottom bracket at a bottom bracket mounting rib ball joint;

d. a piston connector, wherein the piston connector is connected to the piston;

e. a door bracket for mounting to a vehicle door, wherein the door bracket is connected to the piston connector at a door bracket extension, wherein the door bracket extension extends from the door bracket at a door bracket extension mounting angle, wherein the door bracket extension mounting angle is approximately perpendicular, wherein a connection between the door bracket extension and the piston connector is a door bracket extension ball joint;

f. an intermediate connector, wherein the intermediate connector is connected to the door bracket at an intermediate door bracket joint, wherein the intermediate door bracket joint is a swivel joint; and

g. a top bracket for securing to a vehicle frame above the bottom bracket, wherein the top bracket is connected to the intermediate connector at a top bracket axle.

11. The door hinge of claim 10, further comprising:
