Barrier section connection system

1. A vehicle impact barrier comprising at least first and second longitudinally extending barrier sections, each barrier section including a base of sufficient width for the barrier section to be freestanding,

the first barrier section-including a first connecting assembly at one or both ends thereof, the second barrier section including a second connecting assembly at one or both ends thereof, the first and second connecting assemblies each comprising at least a first and second connecting-region, respectively;

wherein the first connecting-region is positioned for engagement with the second connecting-region, each connecting-region having longitudinally-spaced inner and outer holes extending therethrough;

the first connecting-region being configured to engage with the second connecting-region via a two-pronged connecting device, each prong being insertable vertically through one of said inner and outer holes of said first and second connecting-regions, wherein the first connecting-region is movable longitudinally between a first position and a second position relative to the second connecting-region,

wherein in said first position:

the inner and outer holes of said first connecting region are aligned with the outer and inner holes of said second connecting region, respectively, and the connecting device is connected through both sets of inner and outer holes such that the first and second connecting-regions are interlocked and non-pivotable relative to each other; and

side surfaces of said barrier sections are substantially co-planar, and

wherein in said second position:

an end face of the first connecting-region and a contact face of the second barrier section are longitudinally displaced from each other;

the outer holes are aligned and the connecting device is inserted with one prong extending through the aligned outer holes, such that the barrier sections pivot relative to each other; and

said pivotable movement is limited by abutment between outer edges of the end face of the first connecting-region with the contact face of the second barrier section.

2. The barrier as claimed in claim 1 , wherein in the second position, the first connecting region and the second connecting-region are engaged in an angled, nonlinearly aligned configuration.

3. The barrier as claimed in claim 1 , wherein the first connecting-region includes at least one projecting portion, and at least on receiving portion at either end thereof.

4. The barrier as claimed in of claim 3 , wherein the at least one projecting portion and the at least one receiving portion are integral with the body of the barrier section.

5. The barrier as claimed in claim 3 , wherein the at least one projecting portion and the at least one receiving portion are made of substantially the same material as the barrier section.

6. The barrier as claimed in claim 3 , wherein the at least one projecting portion and the at least one receiving portion complement each other in the form of at least one respective alternating protrusion and recess and thereby fit together.

7. The barrier as claimed in claim 3 , wherein the at least one projecting portion is at least one protrusion.

8. The barrier as claimed in claim 7 , wherein there is one protrusion, and the protrusion is substantially centrally positioned.

9. The barrier as claimed in claim 7 , wherein there are three or more protrusions, and the protrusions are evenly spaced with respect to one another.

10. The barrier as claimed in claim 3 , wherein the at least one receiving portion is at least one recess.

11. The barrier as claimed in claim 10 , wherein the at least one recess is in the form of a notch.

12. The barrier as claimed in claim 10 , wherein the dimensions of the recess are sufficient to receive the protrusion and provide enough space for a connection to be effected even when the respective sections are non-coplanar relative to each other along a horizontal axis.

13. The barrier as claimed in claim 3 , wherein the inner and outer holes are orientated parallel to each other through at least one of the at least one projecting portion and the at least one receiving portion.

14. The barrier as claimed in claim 1 , wherein the barrier sections are positioned at an angle of up to 30° with respect to each other.

15. The barrier as claimed in claim 1 , wherein an angle between the barrier sections is between 7.5° to 15° from an aligned configuration.

16. The barrier as claimed in claim 1 , wherein the at least one connecting-region is in the form of a projecting portion.

17. The barrier as claimed in claim 1 , wherein the prongs of the connecting device comprise pins.

18. The barrier as claimed in claim 1 , wherein the barrier sections are constructed from plastic.

19. The barrier as claimed in claim 1 , wherein the barrier is constructed from metal.

20. The barrier as claimed in claim 1 , wherein the barrier section has a hollow portion which can be filled with material to add weight to the barrier section.

21. A barrier constructed from two or more barriers as claimed in claim 1 .

22. The barrier as claimed in claim 1 , wherein the connecting device has at least two shafts aligned in the same plane, wherein the shafts are adapted to be received through the apertures.

23. The barrier as claimed in claim 22 , wherein the connecting device is a U-shaped staple.

24. A method of constructing a vehicle impact barrier by the steps of:

(a) selecting two or more barrier sections as claimed in claim 1 ; and

(b) connecting the barrier sections so that they are engaged to one another in either the first or second position, wherein steps (a) to (b) are repeated with a multiple number of barrier sections until the desired barrier length is achieved.
