Abstract

A mat system includes a surface and at least first and second mat units. Each mat unit includes a respective plurality of blocks interlinked by respective cables that pass through the blocks. Each mat unit includes cable loops along at least one side section thereof. The first and second mat units are positioned on the surface in proximity to each other with cable loops of the first mat unit extending toward the second mat unit and cable loops of the second mat unit extending toward the first mat unit. A plurality of interconnecting blocks are positioned between the first mat unit and the second mat unit. Each interconnecting block includes an underside with downwardly open channels formed therein. The cable loops of the first and second mat units are positioned within the channels of the interconnecting blocks to cover the cable loops. The interconnecting blocks and the blocks forming the first and second mat units are sized, shaped and positioned such that upper surfaces thereof form a substantially continuous surface.

Claims (31)

1. A mat system, comprising:

a surface;

at least first and second mat units, each mat unit comprised of a respective plurality of blocks interlinked by respective cables that pass through the blocks, each mat unit including cable loops along at least one side section thereof, the first and second mat units positioned on the surface in proximity to each other with cable loops of the first mat unit extending toward the second mat unit and cable loops of the second mat unit extending toward the first mat unit;

a plurality of interconnecting blocks positioned between the first mat unit and the second mat unit and thereby connecting the first mat unit and the second mat unit, each interconnecting block including an underside with downwardly open channels formed therein, the cable loops of the first and second mat units positioned within the channels of the interconnecting blocks to cover the cable loops, the interconnecting blocks and the blocks forming the first and second mat units being sized, shaped and positioned such that upper surfaces thereof form a substantially continuous surface.

2. The mat system of claim 1 , wherein the interconnecting blocks are individually removable via lifting vertically upward away from the surface.

3. The mat system of claim 1 , wherein the interconnecting blocks include a tool feature on the upper surfaces thereof to facilitate vertical lifting.

4. The mat system of claim 1 , wherein at least one interconnecting block includes a first extension extending downwardly from an underside of the at least one interconnecting block and adjacent at least one of the channels such that the first extension engages a first one of the cable loops of the first mat unit.

5. The mat system of claim 4 , wherein the at least one interconnecting block includes a second extension extending downwardly from an underside of the at least one interconnecting block and adjacent at least one of the channels such that the second extension of the at least one interconnecting block engages a second one of the cable loops of the second mat unit.

6. The mat system of claim 5 , wherein the at least one interconnecting block includes a third extension extending downwardly from an underside of the at least one interconnecting block and adjacent at least one of the channels such that the third extension engages a third one of the cable loops of the first mat unit.

7. The mat system of claim 6 , wherein the at least one interconnecting block includes a fourth extension extending downwardly from an underside of the at least one interconnecting block and adjacent at least one of the channels such that the fourth extension of the at least one interconnecting block engages a fourth one of the cable loops of the second mat unit.

8. The mat system of claim 1 , wherein the cable loops are each formed by a bend in the respective cables each having a first leg that is interconnected to a second leg by the bend, the first and second legs passing through first and second openings formed in more than one of the plurality of blocks.

9. The mat system of claim 1 , wherein removal of the plurality of interconnecting blocks positioned between the first mat unit and the second mat unit disconnects the first mat unit from the second mat unit such that the first mat unit and the second mat unit can be separated from each other.

10. The mat system of claim 1 wherein the underside of each interconnecting block includes a first T-shaped channel and a second T-shaped channel separated a central downward extension.

11. The mat system of claim 1 , wherein the mat system forms a temporary driving surface.

12. A method of forming a mat system, comprising:

forming a plurality of mat units by arranging blocks in multiple rows and interconnecting the blocks using cables with cable loops being exposed at an edge of the mat units;

arranging the mat units end-to-end such that cable loops of the end-to-end mat units face each other;

placing an interconnecting block between the ends of the end-to-end mat units such that the interconnecting block releasably engages cable loops of the end-to-end mat units to inhibit lateral movement of the end-to-end mat units relative to each other.

13. The method of claim 12 further comprising

arranging the mat units side-by-side such that exposed cable portions of the side-by-side mat units face each other; and

placing a second interconnecting block between sides of the side-by-side mat units such; that the second interconnecting block releasably engages the exposed cable portions of the side-by-side mat units to inhibit lateral movement of the side-by-side mat units relative to each other.

14. The method of claim 13 further comprising disconnecting the side-by-side mat units by lifting the second interconnecting block from its position between the side-by-side mat units.

15. The method of claim 12 further comprising disconnecting the end-to-end mat units by lifting the interconnecting block from its position between the ends of the mat units.

16. A mat system, comprising:

a surface;

at least first and second mat units, each mat unit comprised of a respective plurality of blocks interlinked by respective cables that pass through the blocks, each mat unit including cable loops along at least one side section thereof, the first and second mat units positioned on the surface in proximity to each other with cable loops of the first mat unit extending toward the second mat unit and cable loops of the second mat unit extending toward the first mat unit;

a plurality of interconnecting blocks positioned between the first mat unit and the second mat unit and thereby connecting the first mat unit and the second mat unit, each interconnecting block including an underside with downwardly open channels formed therein, the cable loops of the first and second mat units positioned within the channels of the interconnecting blocks to cover the cable loops, the interconnecting blocks and the blocks forming the first and second mat units being sized, shaped and positioned such that upper surfaces thereof form a substantially continuous surface;

wherein at least one connecting block includes a first downward extension received within a first cable loop of the first mat unit, a second downward extension received within a second cable loop of the first mat unit, a third downward extension positioned within a first cable loop of the second mat unit and a fourth downward extension positioned with a second cable loop of the second mat unit.

17. The mat system of claim 16 wherein the at least one connecting block further includes a central downward extension, the first downward extension and third downward extension located to one side of the central downward extension and the second downward extension and fourth downward extension located on an opposite side of the central downward extension.

18. The mat system of claim 17 wherein the first cable loop of the first mat unit is aligned with and adjacent to the first cable loop of the second mat unit, and the second cable loop of the first mat unit is aligned with the second cable loop of the second mat unit.

19. The mat system of claim 16 wherein the underside of each interconnecting block includes a first T-shaped channel and a second T-shaped channel separated a central downward extension.
