A device for fixing to the chassis frame of an ed ris tho, of a box structure carrying the full description of a roller blind or of a roller shutter

摘要

An end piece 15, engaged in the upper end of each rail for guiding 1 the edges of the shutter, has a horizontal groove 17 intended for serving as a rotating rest for the lower edge 13 of the casing 9 containing the assembly formed by the shutter and its rolling-up mechanism. The rail for guiding 1 also acts as a support for a part 21 ending at its upper extremity with a projecting part 22 placed above the groove 17 of the end piece 15. When installing the casing 9, at the end of the rotation of the edge 13 of the latter in the groove 17, a channel 14 of the upper edge of the casing 9 comes, by way of locking, to be clipped on the projecting part 22. The invention is applicable to shutters which can be rolled up, to roller blinds and to closure devices of this type. IMAGE
