Suspension for roller blind - ensuring safe transport and accurate unrolling on guides

摘要

A mounting for the winding shaft of a diffuser blind, pref. formed from Al or PVC nesting profiles, above lateral guide rails, partic. for an obscuring device, in which a plane retaining element for the blind is fixed on the mounting by insertion on the winding shaft and with the complementary element delimits a space for holding the blind, separated from the lateral supports, the lateral surface of the space being sensibly in alignment with the backs of the guide rails. The mounting prevents lateral movement during transport and use, guarantees correct entry and unwinding of the blind between the guide rails, avoiding the risk of jamming. The retaining device is pref. a rectangular or square sheet having a central circular hole for the winding shaft, together with a right angle flange, with screw holes for fixing. A separate angle pin is fixed by the same screws as the retaining device onto the lower flange of the mounting. The mounting pref. includes a projecting or overhanging piece with attached pins which apply to the retaining element to withstand lateral thrusts. The whole mounting may be prefabricated.
