A mechanism used for hooking and unhooking awnings (fig.2,3,4) operating with sheaves (33) on semi-vertical pipes shaped according to the size of the sheeves and fixed on balcony or floor pipes. This mechanism dispenses the user to hook and unhook its awning manually, especially in case of obstacles encountered in great height. Precisely, the user, without interrupting the rotaty motion of the awning reducer, is able to open or close its awning automatically, with no efforts, via said automatic mechanism; this can be obtained via the mechanism in question with the correct arrangement of newly-designed accessories (fig.1) contained into an entire pipe or a treated section thereof (fig.1 (31)) functionning by exloiting the gravity and the propulsion of the sheaves (33) during the awning descending or ascending. |
