摘要

A retractable device for flexible and omnidirectional flexible elements from a fixed position, which comprises in combination a hollow box with central bore, including supplementary box elements cooperatively providing relatively spaced side walls and having corresponding coupling portions to form a wall peripheral connecting the said sidewalls, said picking portions of supplementary recesses being provided at their protruding edges to provide an aperture adapted to recite and hold a girdle guard thereby preventing relative rotation of said box elements; a snow spindle in the bore of one of the said side walls and provided with end portions that rest on the internal surfaces of the two said side walls in order to preserve them in a predetermined spaced relation; a rotating reel that goes in said spindle and comprises a pair of open side plates in order to provide supports on the spindle itself, as well as provided with circular cups protruding in opposite positions and adapted to contact the internal surfaces of the respective side walls so as to ensure spaces between the peripheral portions of said plates and said side walls and the peripheries of the said soups of circumferentially spaced openings are provided; a hub extending between said plates in the axial direction of said spindle to accommodate their ends in said cups, being provided with tabs that penetrate through openings made in said cups and riveted against the peripheral parts of said plates so as to protrude the cups of the peripheral parts of said plates at a distance greater than the thickness of the tabs provided that the ends of tabs are located within said spaces out of contact with said side walls; a coil spring wound on said spindle so that its ends are respectively connected to the spindle itself and the said hub; and, finally, a flexible chain of such width that fits intimately between said plates and connects with said hub for winding and unrolling with respect thereto and enclosed thereon between said plates, said flexible element passing said said guardrail to the outside of said box to be removed from it in any direction.
