Definitions

  • the present invention relates to an insect screen with a driving device of the net guiding chain and system for facilitating assembly and for correcting the positioning arrangement.
  • the invention finds particular but not exclusive application in the sector of the industry for the production and marketing of components and accessories for door and window frames, such as insect screens, for example insect screens for doors and windows with horizontal sliding, aimed at preventing insects from entering the conventionally inhabited places, be they buildings for civilian, commercial or industrial use, in particular in the industry for the preeminent production and marketing of insect screens and net barrier elements for equipping openings of buildings.

  • insect screens in extreme synthesis they consist in arranging a net barrier interposed to the openings of buildings, typically doors or windows, in such a way as to allow, although with the permanent possibility for air to remain between the internal environment and the external environment, to prevent the intrusion of insects into the internal environments of the building.
  • a solution of the traditional type it is provided to realize a rigid frame supporting a close-mesh net, said frame being peripherically compatible with the sizes of the opening of the doors or the windows which are intended to be equipped with the insect screen itself.
  • the insect screens can be distinguished into two categories.
  • the insect screens of said two categories it is possible to find common elements, which consist of the box, of the type generally made up of an aluminium section or extruded bar, into which one coaxially inserts the winding roller of the net of the insect screen which holds a first end of said net.

  • the box in this solution, contributes to the installation with one or more guides or driving elements, inside which the end of the handlebar and the corresponding side edge of the net slide to and fro.
  • insect screens which, instead of sliding vertically, slide horizontally, imposing to the handlebar a translation movement which is aimed at driving the net along a horizontal axis.
  • said insect screens look very similar to the now described solutions and are recurrent both in roller blinds and in sunshades.
  • one has the habit of using a closed circuit chain, which by engaging, on the one side, a wheel or pulley keyed to the respective winding roller, which is received in a box, causes the controlled winding or unwinding of the net of the insect screen.
