Document Type and Number:

Japanese Patent JP3470793

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To restrain a sound generated by a shutter at strong wind time by providing the shutter on the outdoor side of fittings, and detachably installing a shock absorber opposed to a shutter slat on the fittings.
SOLUTION: Paired guide rails 21 are fixed to an outdoor side end part of a vertical frame 1, and an end part 23a of the shutter slat 23 for constituting a hoisting type shutter is inserted into openings 21a of the guide rails 21. Prescribed clearance is formed between the end part 23a of the shutter slat 23 and the openings 21a of the guide rails 21 by considering deflection of the shutter slat 23 and frictional resistance at hoisting time. A cushioning member 25 is constituted so as to be insertable into the clearance between the guide rails 21 and the end part 23a of the shutter slat 23 at strong wind time to thereby reduce an interval between a shock absorber and the shutter slat when installing the shock absorber to prevent large deflection of the shutter slat at strong wind time using this interval.
