PCT No. PCT/SE86/00584 Sec. 371 Date Jun. 27, 1988 Sec. 102(e) Date Jun. 27, 1988 PCT Filed Dec. 22, 1986 PCT Pub. No. WO87/04286 PCT Pub. Date Jul. 16, 1987.For assembling display boards of varying, predetermined sizes, and of the type comprising two sign element holders (1, 2) determining the height of the display board, one or more back elements (3, 4) determining the width of the display board and arranged to be rigidly connected to flat outer surfaces (5) of the sign element holders (1, 2), and sign elements which are inserted into corresponding grooves in the sign element holders, said holders having substantially L or J shaped cross section with a shank (8) and a foot portion (9), the invention proposes a fixture comprising a flat plate (14) which is somewhat larger than the largest predetermined size of the display boards and which has a plurality of parallel grooves (19 to 26) to receive the foot portions (99) of the sign element holders (1, 2) without friction or play, the grooves (19 to 26) being arranged in a coordinate system with a first groove (19) located on the y-axis and the remaining grooves (20 to 26) being arranged with predetermined distances from the first groove with increasing x-values corresponding to predetermined widths of display boards. The grooves (19 to 26) start from the x-axis with which one end of a sign element holder (1, 2) placed in a groove is to coincide during assembly, and the grooves (19 to 26) are sufficiently long to receive sign element holders (1, 2) of varying lengths corresponding to predetermined heights of display boards. |
