NON-SLIP STRUCTURE |
摘要 |
<p>This invention relates to a non-slip structure, which is highly efficient in preventing a slip with no trouble caused by a through hole, thereby enhancing reliability. The non-slip structure of this invention is characterized in that a portion of a metal plate such as a steel plate and the like is sheared so as to form cutting lines (a pair of lateral side cutting lines and a joining cutting line) for forming a protruded piece and, at the same time, the protruded piece is pulled up along the cutting lines to a height, which does not exceed the thickness portion of the steel plate so as to raise the shearing surface (edge), so that the sheared surface does not form a gap nor any through hole in contacting the steel plate.</p> |
