Vehicle barrier

1. A vehicle barrier, comprising:

a longitudinally extending beam positioned vertically above a ground level and separating a protected side from an attack side, the beam comprising beam sections;

each of the beam sections comprising a web oriented generally parallel to the ground level;

a line post positioned on the attack side and comprising a bottom end positioned in a concrete foundation and a frame;

a line brace having a first brace end located with the frame and a second end secured in the concrete foundation such that the line brace and the concrete foundation form adjacent sides of a vertex on the protected side; and

adjacent beam sections pivotally connected to each other at the frame and the first brace end.

2. The vehicle barrier of claim 1 , wherein the adjacent beam sections are pivotally connected by a pin in connection with the frame and the adjacent beam sections.

3. The vehicle barrier of claim 1 , wherein the adjacent beam sections are pivotally connected by a pin in connection with the frame, the line brace, and the webs of the adjacent beam sections.

4. The vehicle barrier of claim 1 , wherein the adjacent beam sections comprise overlapping beam plates; and

the adjacent beam sections are pivotally connected by a pin in connection with the frame and the overlapping beam plates.

5. The vehicle barrier of claim 1 , wherein:

the frame comprises a rectangular member extending from the post toward the protected side, the rectangular member providing a pocket;

the first brace end is disposed inside of the pocket; and

the adjacent beam sections are pivotally connected by a pin in connection with the rectangular member and the adjacent beam sections.

6. The vehicle barrier of claim 5 , wherein the pin terminates inside of the pocket.

7. The vehicle barrier of claim 5 , wherein the first brace end is box-shaped.

8. The vehicle barrier of claim 7 , wherein the pin terminates inside of the first brace end.

9. The vehicle barrier of claim 1 , wherein

the frame comprises a rectangular member extending from the post toward the protected side, the rectangular member forming a pocket;

portions of the adjacent beam sections overlap above the rectangular member;

the first brace end is disposed inside of the pocket; and

the adjacent beam sections are pivotally connected by a pin in connection with the rectangular member and the adjacent beam sections.

10. The vehicle barrier of claim 9 , wherein the portions are plates.

11. The vehicle barrier of claim 9 , wherein the pin terminates inside of the pocket.

12. The vehicle barrier of claim 9 , wherein the first brace end is box-shaped.

13. The vehicle barrier of claim 12 , wherein the pin terminates inside of the first brace end.

14. The vehicle barrier of claim 1 , wherein:

the frame forms a cavity between a top shelf and a bottom shelf;

portions of the adjacent beam sections are positioned in the cavity; and

the adjacent beam sections are pivotally connected by a pin in connection with the top shelf, the portions, and the bottom shelf.

15. The vehicle barrier of claim 14 , wherein the portions are plates.

16. The vehicle barrier of claim 14 , wherein the pin is in connection with the first brace end.

17. The vehicle barrier of claim 16 , wherein the first brace end is box-shaped and the pin terminates inside of the first brace end.

18. The vehicle barrier of claim 1 , wherein:

the frame comprises a cavity between a top shelf and a bottom shelf and a rectangular member forming a pocket below the bottom shelf;

portions of the adjacent beam sections are positioned in the cavity;

the first brace end is disposed inside of the pocket; and

the adjacent beam sections are pivotally connected by a pin in connection with the top shelf, the portions, and the bottom shelf.

19. The vehicle barrier of claim 18 , wherein the pin terminates inside of the pocket.

20. The vehicle barrier of claim 18 , wherein the first brace end is box-shaped; and

the pin terminates inside of the first brace end inside of the pocket.
