PURPOSE:To enable assembly of extinguishable pattern made of materials in which adhesive is hard to use, easily and instantly, by integrally planting magnetic attracting members, at the time of fabrication, to the mutual bond boundary surfaces of split partial models. CONSTITUTION:For example, in model formed with naphthalene base extinction pattern material, an iron piece A and a magnet D are integrally planted in insert form on respective bond boundary surfaces a, b of split partial models A and B, on the model A side and model B side, respectively. The iron piece C is projected from the boundary surface a, and the magnet D is indented from the boundary surface b (in this case the iron piece and magnet may be placed in opposite positions). By assembling said split partial models A, B, they are magnetically attracted in the bond parts, and sealing coat E is applied to the corner parts of the bond part, so that an extinguishable pattern 1 may be completed. |
