Document Type and Number:
Japanese Patent JPH1157113
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To draw a correct line by forming projections projecting at the ground side of the support body of a guide rail which is constituted of the guide of wheels in a lining machine and of the support body for fixing the guide in a sports stadium. SOLUTION: The guide rail is constituted of the guide 1 for travelling of the wheels of the lining machine and the support body 2 such as a base plate, etc., for fixing the guide and the support body 2 is provided with the downward projections 3. The projections 3 are formed by bending the both end parts of the support body 2 to be in a curved surface shape in a contact direction with lawn. The projections 3 can be the ones which are intermittently formed in the length direction of the rail but they are favorable to be continuously formed. Besides, it is preferable that more than two projections 3 are formed concerning a stability for preventing the rail from being easily inclined at the time of considering the cross section of the rail. Thus, the line is drawn by the lining machine without generating the position deviation of the line.
