摘要

The shutter has a rolling shaft with two ends supported by a bearing and a support (1) formed from a metal bar, where the bar is foldable in two directions such that two bends (3, 4) separate a foot (2) and an upper part (5) of the support. The fold locates lateral surfaces of the same side of the foot and the upper part in parallel spaced surfaces, and slides include a tubular chamber for housing the foot.
