Abstract

This invention relates to a tooling system comprising a plurality of elements (22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64) having tessellating sides arranged in an array. The elements of the array being movable between a closed position in which the elements contact one another, and an open position in which the elements of the array are spaced apart. In the open position the elements are capable of vertical movement relative to one another. Drive means for opening and closing the array are provided and the elements are mounted on supporting rails (2, 4, 6, 8, 10, 12, 14) and are driven by the drive means between the open position and the closed position along a drive axis which is at angle to the longitudinal axis of the supporting rails.

Claims

1. A tooling system comprising a plurality of elements arranged in an array and s mounted on supporting rails, the elements of the array being movable between a closed position in which the elements have tessellating sides and the sides of adjacent elements contact one another and are secure in position, and in an open position in which the elements of the array are spaced apart and are capable of vertical movement relative to one another, and drive means for opening and closing the array and which drives the array to between open and closed positions, wherein the elements are mounted on supporting rails which supporting rails are configured and shaped so that they can support more than one element in the any but do not support adjacent elements of a row or column of the array and the supporting rails are driven by the drive means between the open position and the closed position along a drive axis that is at an angle to the longitudinal axis of the supporting rails.

2. A tooling system according to claim 1, wherein the elements are substantially rectangular in plan, and the drive axis is substantially parallel to the sides of these elements.

3. A tooling system as claimed in claim 1, wherein the supporting rails are mounted at in angle of 45°

or less to the drive axis.

4. A tooling system as claimed in claim 1, wherein the supporting rails are mounted at an angle of 30°

to the drive axis.

5. A tooling system as claimed in claim 1, wherein the supporting rails are provided with engagement means which cooperate with the drive means and are perpendicular to the drive axis.

6. A tooling system as claimed in claim 1, wherein the supporting rails are provided with engagement means which cooperate with the drive means and are at an angle to the drive axis.

7. A tooling system as claimed in claim 1, wherein the elements of the array are provided with inter-element interlocking and/or alignment features.
