<p>The object of the present invention is union means for accessories for operating winding blinds which due to their special configuration ensure an unequivocal insertion of the crank tube and the transmission mechanism or of the actuation crank and the tube, also ensuring that the loads are transmitted between the crank tube and the mechanism to which said tube is joined, freeing the union elements from having to withstand said loads so that said union elements can be made of lightweight materials with low requirements for withstanding loads, allowing to obtain a lighter mechanism.</p> |
