Device with retractable anti-roll means, and use thereof in wire dispensing reels

Application of a device with anti-rolling means for controlling rolling of a wire dispensing reel comprising the wire dispensing reel having a cylindrical body flanked by two end flanges of larger diameter, at least one of said end flanges comprising said device with retractable anti-rolling means, comprising a circular rolling flange delimited by a peripheral rolling edge provided with at least one radial anti-rolling projection radially movable between a deployed position and a retracted position, to oppose or selectively allow rolling of the rolling flange on a peripheral rolling edge of the rolling flange comprising a plurality of retractable radial anti-rolling projections, angularly distributed along the periphery of the rolling flange, and simultaneously moved in a radial direction between a deployed position and a retracted position by a single controlling member that can be actuated by the user.

A device with retractable anti-rolling means, comprising a circular rolling flange delimited by a peripheral rolling edge provided with at least one radial anti-rolling projection radially movable between a deployed position and a retracted position, to oppose or selectively allow rolling of the rolling flange on a peripheral rolling edge of the rolling flange comprising a plurality of retractable radial anti-rolling projections, angularly distributed along the periphery of the rolling flange, and simultaneously moved in a radial direction between a deployed position and a retracted position by a single controlling member that can be actuated by the user

• wherein the radial anti-rolling projections are driven in radial movement by a coaxial controlling ring mounted on a face of the rolling flange so that the rolling flange can rotate between a first angular limit position in which the radial anti-rolling projections project and a second angular limit position in which the radial anti-rolling projections are retracted within a circular contour defined by the peripheral rolling edge,
• said coaxial controlling ring comprising leaf springs extending tangentially from the peripheral edge of the controlling ring.
