A SCREENING APPARATUS FOR SCREENING AN OPENING MADE IN A WALL
A screening apparatus (100) for screening an opening (2) made in a wall (5). The opening can be a window or a door. The screening apparatus (100) comprises: a sheet (1) for screening the opening (2) made in the wall (5), which can be a mosquito screen, a curtain or pleated blind; a movable bar (3), also known as a bar handle; a chain (36), or in any case a flexible guide with hinged elements, which is insertable internally of the movable bar (3); a flexible belt (6), for example made of metal or plastic, which is insertable internally of the movable bar (3); a housing (31), upper profiled element, which is provided with a first through-opening (41) for passage of the portion of flexible belt (7) and of the upper edge portion (23) of the sheet (1); a plurality of flexible teeth (45), for example brushes, which are borne by the housing (31), and which are designed to enable the flexible belt (6) to pass beyond them so as to insert in the movable bar (3). The screening apparatus (100) is configured in such a way that the flexible belt (6) and the chain (36) tend to maintain the movable bar (3) orientated vertically, further comprising a guide (81) for guiding the portion of flexible belt (7) internally of the housing (31). The first guide (81) in turn comprises: one or more guide walls (50); and the plurality of flexible teeth (45). The one or more guide walls (50) and the first plurality of flexible teeth (45) are near to one another so as to prevent the portion of flexible belt (7) from bending until passing beyond the first plurality of flexible teeth (45), with the consequence of increasing the resistance to axial compression of the portion of flexible belt (7) which is housed in the housing (31) and limiting the problem of instability at peak load.
