<P>PROBLEM TO BE SOLVED: To solve a problem that labor hour and welding are required in a conventional safety net, as it has a square-shaped frame piece remaining on the periphery of an opening section formed on a square frame body, and mounting holes formed through the frame piece, and is constituted by attaching edge sections of a net material (or a peripheral section of punching metal) to a surface of the frame piece by a welding means, so it needs a process for forming the opening section through the frame body, and a process for cutting the net according to dimensions of the opening section, and attaching the whole edge sections of the material of the net by welding. <P>SOLUTION: A safety net attached to a window of equipment or an instrument, includes the frame piece raised on the frame body, a number of holes for bending the frame pieces, the opening section of the frame piece, and the net disposed on the opening section. Both edges of the material in one direction, of the net are inserted to a number of holes formed on opposed faces of the frame piece, and both edges of the material of the another direction, of the net are inserted and supported in the another directional opposed holes to attach the net on the frame piece. <P>COPYRIGHT: (C)2013,JPO&INPIT |
