Abstract
Description
- This invention relates to those devices, known as mosquito nets, which prevent the insects from entering closed rooms via the doors or windows.
- Mosquito nets of known type generally comprise an inverted U-shaped frame consisting of two parallel and opposite equal guides, which are securely fixed to the window jambs and to the top of which there is positioned a box securely fixed to the lintel of the window compartment. The box contains an idly mounted roll about which the net is wound.
- The roll is provided with usual elastic return means which automatically rewind the net wound on the roll.
- Although known mosquito nets suitably perform their function, they are complicated, laborious and costly to install. In this respect, not only must the uprights and the box be constructed with exactly the same measurements as the window compartment, but these must be fixed by screws screwed into holes made in the walls.
- The object of this invention is to provide a quick-installation mosquito net, ie one which for its fixing into the window compartment does not require any holes to be made in the compartment walls, and which adapts to the window compartment without the need for specific fixed and precise measurements.
- The invention attains these objects by means of a mosquito net consisting of an inverted U-shaped frame comprising an upper box of horizontal axis provided with lower insertion means for the connection of two equal lateral, vertical, parallel and opposite guides.
- Said box is provided with upper first elastic means via which it rests under the lintel of the window compartment, and with lateral second elastic means via which it rests against the window jambs, to maintain the mosquito net forcibly locked within the window compartment in which it is installed.
- The functional and constructional characteristics of the invention will be more apparent from the ensuing description of a preferred embodiment thereof given by way of non-limiting example and illustrated on the accompanying drawings.
- Figure 1 is a front view of the invention.
- Figure 2 is a section on the line II-II of Figure 1.
- Figure 3 is a section on the line III-III of Figure 2.
- Figure 4 is a partial section on the line IV-IV of Figure 3.
- Figure 5 is an exploded side view of some components of the invention.
- Figure 6 is a section on the line VI-VI of Figure 1.
-
- Figure 1 shows the mosquito net, which is indicated overall by 1 and is mounted in the
window compartment 2. - The
mosquito net 1 comprises anupper box 3 positioned at the top of two equal lateral, vertical andopposite guides 4. - The
box 3 comprises an internally hollow profiledsection piece 5 provided with alower aperture 50 through which thenet 6 for screening the window compartment passes. - Said
section piece 5 contains the hollow slottedroll 7 on which said net 6 is wound. - With reference to Figure 3, the roll comprises at is ends two cup-
shaped plugs - The
plug 8 is idly mounted on the centrallyhollow pivot 10 of the flange 11, which lowerly comprises ashank 110 for securing the rightlateral guide 4. - The
plug 9 is fixed to the tubular element by ascrew 90, and is mounted on a centrallyhollow pivot 12 branching from theflange 13, which lowerly comprises ashank 130 for securing the leftlateral guide 3. - Between the
flange 13 and theplug 9 there is interposed a conicalhelical spring 14, the purpose of which is to maintain theflanges 13 and 11, which constitute the ends of thebox 3, in forced contact with the jambs of thewindow compartment 2. - Specifically, the
slotted roll 7 is provided withexternal lightening slots 70 and with aninternal keying recess 71, which receives the return means for automatically winding thenet 6. - Said means comprise a
spring 15, the left end of which, with reference to Figure 3, is screwed onto the threaded part of theshaped head 91 which branches from the front edge of theplug 9. The other end of the spring is screwed onto the threaded front part of a hollow profiledbush 16, which torsionally engages thekeying recess 71 by means of thetooth 160. - When the
net 6 is lowered, theroll 7 rotates and drags thebush 16, which is torsionally engaged with it. Consequently the spring is subjected to a twisting moment and tends to lengthen, to become loaded. - Each of the
flanges 11 and 13 comprises in proximity to its upper edge two identical symmetrically opposing profiledapertures flat spring 20, the purpose of which is to maintain the mosquito net 1 elastically locked within the window compartment in a vertical direction. - To ensure that the mosquito net is sealed along the edge of the box upper surface, a strip of elastomeric material, not shown, is applied.
- It should be noted that instead of the flat springs, elastic means of elastomeric material can be provided.
- With reference to Figures 2 and 4, the
section piece 5 has alower edge 51 shaped to receive aframe 21 which supports a pair of idly mountedrollers 22. - Said
frame 21 consists of two equal and opposite profiledmembers 210 joined together by acrosspiece 211 and each comprising two fork-shaped apertures 212 for receiving thehubs 220 of therollers 22. - The purpose of the
rollers 22 is to limit the bending of theroll 7 about which thenet 6 is wound and to prevent the net from sliding against thesection piece 5 and undergoing damage. - The positioning of the
frame 21 and the number offrames 21 depend on the width of the window compartment. - It should be noted that the movable front edge of the
screening net 6 is provided with ausual gripping bar 60, shown in Figure 1, which when the net 6 screens the window compartment is secured in proximity to the lower ends of theguides 4, by known means, not shown. - It should also be noted that the
guides 4 are provided with usual anti-intrusion andguide brushes 40 for thescreening net 6, as shown in Figure 6, and that thesection piece 5 comprises ashaped portion 500 arranged to make contact with thenet 6 to prevent the intrusion of insects through thebox 3. - Finally, the mosquito net of the invention can be provided with a device for regulating the unwinding of the
net 6, such as that described in European patent application 0151827 in the name of the present applicant. - The aforedescribed means allow simple and quick installation of the
mosquito net 1 within thewindow compartment 2, it being sufficient to rest thebox 3 against the window lintel and insert theguides 4 by mounting their upper ends over the appropriate securing shanks.
