CONSTITUTION:A main top board 1 is planar and is mounted on both sides thereof with rotatably auxiliary top boards 2 which are fixed by hooking fixtures 3 onto fixing pins 4. The fixtures 3 are freely rotatably coupled to the auxiliary top boards 2 by means of shafts 3a, and formed in their forward end parts with engaging recesses. Further, the top board 1 may be variously changed in its shape so as to provide a wide planar surface, a curved surface or the like.</p> |
