Abstract (en)
Fabric roller blind, which comprises: two vertical uprights (7) fixed to a portal along respective sides of an opening (A) of the portal itself; a take-up roller (4) rotatably supported between the two vertical uprights (7); a fabric (5) rollable around the take-up roller (4); a return spring (8) mechanically associated with the take-up roller (4) and adapted to exert an elastic torque on the latter, in a manner so as to be elastically opposed to the unwinding of the fabric (5) and facilitate the re-winding of the fabric (5) itself; means (10) for adjusting the tension of the return spring (8) mechanically connected to the take-up roller (4) in order to vary the tensioning of the return spring (8). The adjusting means (10) of the blind (1) comprise: an actuator member (13) rotatably mounted inside at least one of the uprights (7) and accessible by means of a hole (71) made on the same upright (7) from within the opening (A) such that the actuator member (13) is susceptible of being rotated into different angular positions in which the actuator member (13) can be engaged by means of provided mechanical engagement means (20); and transmission means (18) for transmitting the rotation torque of the actuator member (13) to the take-up roller (4), consequently varying the tensioning of the return spring (8).
