  • the present invention relates to a winding closure device comprising a curtain composed of juxtaposed blades, a fixed axis whose ends are mounted in a fixed frame, at least one coil provided with at least one spiral balancing spring, the outer end is integrally coupled to said coil, this coil being mounted on the fixed axis and being integral with at least one upper blade of said curtain around which it is wound, this closing device comprising a mechanical locking device arranged for stop the curtain falling in the event of a break in the balancing spring or in the fixing of this spring.
  • the invention relates more particularly to the rolling metal curtains of garages, storefronts, industrial or other buildings, the rolling grilles of shop windows or other premises, the blinds, the flexible doors and all other similar closures with rolling up above a bay.
  • curtains, blinds, grilles or other rolling closure devices are traditionally balanced by one or more coil springs of the barrel spring type.
  • These springs consist of a metal blade of rectangular section wound flat in a spiral. After being wrapped around an axis, this blade is placed in a metal box called coil, drum, barrel, pie chart or spring box.
  • spiral springs have the function of restoring the energy stored in the form of a couple thanks to an angular deformation of several turns. The energy thus stored during the descent of the closing curtain is returned when it is opened.
  • Centrifugal type fall arrest systems which are capable of detecting an overspeed of the curtain, but incapable of detecting the rupture of a single spring. These devices are used on generally motorized closings with rotating central axes.
