GUIDE RING FOR LIFTING CORD OF SHIELDING MATERIAL
Document Type and Number:
Japanese Patent JP2015202299
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a guide ring that can be used for both of a shielding material of a plain style having a loop ring positioned in a perpendicular plane and a shielding material of a sharp style having the loop ring positioned in a horizontal plane without increasing types of parts.SOLUTION: A guide ring 30 for a lifting cord 13 of a shielding material 11 includes a fitting ring part 31 fitted in a loop ring 11b mounted to the shielding material 11, a loosely inserted ring part 32 with the lifting cord 13 loosely inserted therein, and an engagement part 33 for removably engaging the loosely inserted ring part 32 in the fitting ring part 31. The engagement part 33 is configured such that a plane including the loosely inserted ring part 32 rotates centering on a straight line passing the center of each ring hole of the fitting ring part 31 and the loosely inserted ring part 32 to the plane including the fitting ring part 31 so as to be switched between a first engagement state where both planes match and a second engagement state where both planes are perpendicular to each other.
