Kind Code:
B2
Abstract:
To provide an assisting tool for marking which enables one worker to easily perform marking work on an irregular face not allowing sticking of a pin of a fixing piece, a stepped face or a vertical face, when performing the marking work with a marking tool.SOLUTION: In an assisting tool 2 for marking, the center of a rectangular plate member 11 is mountain-folded, a lower part of a tip end of a member 13 or 14 branched into two by being mountain-folded is formed thin or in parallel to a mountain-folded part 12, and grooves 23, 24, 25 and 26, 27, 28 allowing passing of ink threads to cross orthogonally undersurfaces 17 and 21 of the tip ends are provided. The undersurfaces 17 and 21 of the narrow and separated parallel two faces serve as contact faces, preventing slipping even on an irregular face, and allowing stable contact at a stepped face by being branched into two. By placing a fixing piece on an inner face 18 of the member 13, and by passing the ink thread through the grooves 23, 24 or 25, the assisting tool 2 for marking serves as the fixing piece, allowing marking by one worker.SELECTED DRAWING: Figure 3
