Description

The present invention relates to a shutter case, and more particularly, to a shutter case made up of a plurality of curved case plates that are connected in the opening width direction between left and right brackets attached to a housing.

A so-called round case is known as a shutter case that houses a winding shaft and a shutter curtain wound around the winding shaft (Patent Document 1). The round case is formed by curving a metal case plate in a substantially arc shape in cross-section, with the upper end attached to the housing side and the lower end attached near the lintel.

The curved case plate forming the round case is short with respect to the opening width dimension, and a shutter case is formed by connecting a plurality of curved case plates in the opening width direction while overlapping the end portions in the width direction. The

In such a shutter case, there is a case where an inspection port is formed for maintenance to check the inside of the case. Maintenance is required near the end of the take-up shaft (usually located at the drive-side end or driven-side end of the take-up shaft when a member requiring maintenance is provided in the shutter case) Therefore, the inspection ports are formed by sliding the case plates at the left and right end portions to slide relative to the adjacent case plates.

However, the surface of the curved case plate constituting the round case has no irregularities that trigger the displacement of the curved case plate, so that a bar or the like can be inserted between the end of the curved case plate and the bracket to pry it open. However, the workability is poor due to the work at a high place and the work in a narrow ceiling in many cases. Further, there was no effective means for returning the shifted curved case to its original position after the curved case plate was shifted to form the inspection port.
