Abstract (en)
[origin: WO9941460A1] A grid structure (1) includes a number of cells (2, 3, 4), each non-peripheral cell (4) being spaced apart from and connected to a number of nearest adjacent cells (2, 3, 4) the centers of the cells (2, 3, 4) define a first array of points. The cells (2, 3, 4) define a number of openings and the size of the openings are greater than the size of the cells (2, 3, 4). The centers of the openings define a second array of points. The spacing of the points in the second array is substantially identical to the spacing of the points in the first array. In addition, the peripheral cells (2, 3) in the array comprise coupling means (6, 7) to permit the grid structure (1) to be coupled to a like grid structure (1a). The coupling means (6, 7) comprise a first coupling member (6) on a peripheral cell (3) of the grid structure (1) and a second coupling member (7) on a peripheral cell of the like grid structure. The first and second coupling members (6, 7) are adapted to engage with each other, at least partially within one of the peripheral cells (2, 3), to couple the grid structure (1) to the like grid structure (1a).
