Abstract

The blind has a roller mounted at each end on slotted brackets (2), with a small tongue (5) bent towards the roller (1). A head extends outside the roller to form a milled knob (9) with teeth (10) which engage with the tongue (5) to immobilise an internal screw thread (8). On the screw is a nut (11) which cannot turn in relation to the roller. Therefore, when the screw (8) is turned, the nut (11) is displaced lengthwise in the roller (1). A pin (14) is inserted through the screw thread (8), having a second knob (15) which engages in the notch (4) of the bracket. The pin (14) extends beyond the screw (8) against the inside edge of which is a stop-collar, the pin then has a threaded section (20) on which is placed a nut (21) which has a notch (12) cooperating with lengthwise stop (13) preventing it from turning.
