Title:
BOUNDARY MATERIAL FOR GROUND
Document Type and Number:
Japanese Patent JP3785286
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily and surely perform connection between boundary materials for a ground by integrally forming a connection part for connecting the adjacent boundary materials for the ground on both the ends of the boundary material for the ground.
SOLUTION: A connection part for connecting adjacent boundary materials 10 for a ground is integrally formed on both the ends of the boundary materials 10, 10 for the ground for drawing a boundary line on the ground. This connection part is made vertically fitting male-female fitting structure, and constituted of male connection parts 18, 18 and a female connection part 19. Particularly, the horizontal directional cross section of the connection part is preferably formed of a polygon. In addition, the boundary display part of a shape different on both the upper and lower side edge parts of the boundary material 10 for the ground is formed, and the inner shape or the outer shape of both the boundary display parts may be formed of a shape capable of being connected by a common connection tool.
