Definitions

  • the invention relates to a flexible screening apparatus, such as for example a curtain or an anti-insect net that is applicable to roller shutters of windows and/or French windows of buildings, and assembling means thereof.
  • mosquito nets are known and widely used.
  • the latter consist of frames, normally rectangle- or square-shaped, on which a net is constrained, the meshes of which have dimensions such that insects, such as for example mosquitoes and flies, cannot pass through them.
  • the net can be made of many various materials, for example nylon.
  • the mosquito nets prevent the insects from penetrating inside the latter, thus allowing the windows and/or French windows to be left open and thus enabling the rooms inside the building to be ventilated.
  • mosquito nets are known the frames of which have a height that is significantly lower than that of the window spaces to which they have to be applied. After inserting the frame uprights into the guide grooves of the roller shutter, the frame is positioned such that its bottom crosspiece rests on the sill of the window. The roller shutter is then lowered until the lower edge of the latter matches the upper crosspiece of the frame. In this way, a portion of the window space is occupied by the roller shutter, whilst the remaining portion is occupied by the frame of the mosquito net, through the net of which light and air can pass, but not insects.
  • a drawback of this mosquito net consists of the fact that if a user wishes to access the sill of the window, he is forced to perform a series of operations. In fact, it is first necessary to rewind the roller shutter, then extract the uprights from the guide grooves and lastly remove the frame. In order to again place the mosquito net in position, it is necessary to insert the uprights into the guide grooves, rest the lower crosspiece of the frame on the sill and then lower the roller shutter until the lower edge of the latter again matches the upper crosspiece of the frame.
  • the maximum height extent of the frame is rigidly defined by the preset length of the respective uprights, the user cannot vary at will the area of the portion of space of the window occupied and thus protected by the mosquito net, unless for each window or French window he provides a series of mosquito nets of the known type, provided with frames having pairs of uprights of different lengths.
  • An object of the invention is to improve the known flexible screening apparatuses that are applicable to windows and/or French windows.
  • Another object of the invention is to improve known anti-insect net apparatuses that are applicable to windows and/or French windows.
  • a further object of the invention is to provide a flexible screening apparatus, applicable to a window and/or French window, that enables a respective user to access the sill and/or terrace in a substantially rapid manner.
  • Another further object of the invention is to provide a flexible screening apparatus, which is applicable to a window and/or French window, which, in use, enables a respective user to access the sill and/or the terrace without requiring significant expenditure of effort.
  • a still further object is to provide a flexible screening apparatus that can occupy the entire height extent of the space of a window and/or French window.
  • Another still further object is to provide a flexible screening apparatus, which is applicable to a window and/or French window, which is provided with a substantially simplified structure that therefore enables the respective production and assembling time and costs to be reduced.
  • an apparatus arranged to be associated with a roller shutter of a building, consisting of first bar means, associable with a portion of said roller shutter, second bar means and flexible screening means, said first bar means and said second bar means being connected to end portions, which are not adjacent to one another, of said flexible screening means.
  • an apparatus which is arranged to be associated with an opening of a building and consisting of first bar means, second bar means and flexible screening means, said first bar means and said second bar means being fixed to end portions, which are not adjacent to one another, of said flexible screening means and being furthermore provided with fixing means configured in such a way as to enable said first bar means and/or said second bar means to be alternatively locked close to, or removed from, edge portions of said opening.
  • an apparatus is provided that is arranged to be associated with an end portion of flexible screening means, comprising bar means that is reducible in length in a telescopic manner, said bar means being arranged to alternatively enable said flexible screening means to be inserted into, or extracted from, guide means of a roller shutter.
  • a flexible screening apparatus such as an anti-insect net or a curtain, which is applicable to a window and/or French window and enables a user to access the respective sill and/or terrace without removing the apparatus or rewinding the roller shutter, and thus in a substantially rapid and effortless way compared with known apparatuses.
  • the flexible screening means is associated with a frame devoid of rigid uprights and can therefore occupy variable portions of a window space without being subject to the limits of height extent imposed by the frames of known apparatuses.
  • the fixing means is made in such a way as to enable the user to insert the latter inside the guide grooves of the roller shutter of the window, or French window, so as to immobilise at a desired height the first bar means and/or the second bar means.
  • the first bar means as a stopping element for the terminal slat of the roller shutter and lower the latter to make the adjacent slats match one another.
  • the slits are thus shut that normally exist between the adjacent slats of a roller shutter when the latter is lifted up and which would allow insects to pass through the window despite the presence of the screening apparatus.
  • the fixing means furthermore enables the second bar means to be kept matching a sill of a window, or the threshold of a French window, thus preventing a gust of wind from lifting up the second bar means and accidentally creating an undesired gap in the screening apparatus.
  • the fixing means is made in such a way as to enable the user to lock the first bar means and/or the second bar means directly against the jambs of the window or French window.
  • the apparatus comprises profiled elements associable with the jambs of the window or French window space and are provided with guide grooves in which the fixing means can be inserted.
  • assembling means is provided arranged to assemble flexible screening means on a roller shutter of a building, comprising first assembling means and second assembling means, said first assembling means and said second assembling means being engageable with each other by means of respective first Velcro portions and second Velcro portions.
  • assembling means is provided, arranged to assemble flexible screening means on a roller shutter of a building, comprising first assembling means and second assembling means, said first assembling means and said second assembling means being engageable with each other by means of respective first tooth means and second tooth means.
  • assembling means is provided, arranged to assemble flexible screening means on a roller shutter of a building, comprising first assembling means and second assembling means, said first assembling means and said second assembling means being engageable with one another in such a way as to form connecting-rod means.
  • assembling means is provided that is suitable for assembling the flexible screening means on the roller shutter of a window and/or French window, which enables the user to access the respective sill and/or terrace in a significantly rapid manner and with reduced expenditure of effort.
  • bar means is provided arranged to be fixed to end portions of flexible screening means, said bar means comprising first half-shell means and second half-shell means arranged to be snap-engaged with each other in such a way that said end portions are at least partially interposed between said first half-shell means and said second half-shell means.
  • snap-assemblable bar means is provided, which substantially simplifies the structure of the device, thus reducing the time and costs necessary to produce and assemble the latter.
  • a flexible screening apparatus 1 for example comprising an anti-insect net 6, is applied internally to a window F of a building E.
  • the apparatus 1 consists of a first bar 2 and a second bar 3, both of which are arranged parallel to a sill D of the window F and are made by using profiled elements of the known type, for example in plastics, extending longitudinally.
