Title:
DUSTPROOFING HOUSE
Document Type and Number:
Japanese Patent JP2542760
Kind Code:
B2
Abstract:
PURPOSE: To completely isolate only a portion to be assembled or inspected from the outside so as to assemble or inspect such a large article which cannot be put in a dustproofing house by making the protrusion of the article to be assembled or inspected protrude to the outside of the dustproofing house from a through hole provided in a peripheral sheet.
CONSTITUTION: A through hole 6 is formed at roughly the center portion of a sheet which covers the circumferential four sides of the side plate 2 and the end panel 3 of a supporting frame 1, and a tubular body 7 of roughly the same diameter as the through hole 6 is projected from the through hole 6 to the outdoor side by a predetermined length. The tubular body 7 is made by a sheet made of the same material as the sheet covering the circumferential four sides of the side face 2 and the end panel 3 of the dustproofing house. The protruding part 5 of an article located within the dustproofing house can be projected to the outside through the through hole 6 and the tubular body 7. A notch 8 is formed in the respective portions of the side face 2 and the end panel 3 beneath the tubular body 7. The notch 8 is formed continuously from the end of the tubular body 7 to the lower end of the sheet via the edge end of the through hole 6. After assembling and inspection of the article are completed, the sheet on each side is wound upward or crosswise around the through hole 6 so that the dustproofing house can easily be removed.
