Title:
ERECTING TOWER FOR BALL PROTECTION NET
Document Type and Number:
Japanese Patent JPH06254194
Kind Code:
A
Abstract:
PURPOSE: To reduce the installation space, favorably reduce weight, and improve tensile strength and vertical load resistance.
CONSTITUTION: A net 3 can effectively be prevented from contacting a net supporting part 2 even if the net 3 is fanned by a strong wind and expanded, by the warp of the shape of the whole of the met supporting part 2 to an arcuate form and by supporting the net 3 by the upper and lower edge parts of the net supporting part. Further, when at least the lower part of the net supporting part 2 is formed to a small width shape, the dimension of a basic body part 1 can be reduced by that portion.
