Definitions

  • the present invention relates to a winding closure device comprising a curtain composed of juxtaposed slats, a fixed axis whose ends are mounted in a dormant frame, at least one coil provided with at least one spring balancing spiral whose outer end is integrally coupled to said coil, this coil being mounted on the fixed axis and being integral with at least one blade upper of said curtain around which it is wound, this closing device comprising a mechanical locking device arranged to stop the fall of the curtain in case of breakage of the balancing spring or of the fixing of this spring.
  • the invention relates more particularly to metal curtains with winding garages, storefronts, industrial or other buildings, grids winding of shop windows or other premises, blinds, flexible doors and all other similar closures for winding over a bay.
  • curtains, blinds, grilles or other roller shutters are traditionally balanced by one or more spiral springs of the spring type barrel.
  • 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 under the forms a couple thanks to an angular deformation of several turns. Energy thus stored during the descent of the curtain of the closure is restored during its opening.
  • closures are generally not protected in the event of a fault, impact or wear of the balancing system, for example in the event of rupture of the spiral spring, which makes them dangerous for the user.
  • the rupture of the spiral spring can cause the curtain to drop rapidly, representing a mass of up to several tens and even several hundred kilograms, this mass being located above the user or the public in the case of a storefront grille store for example.
