A flange (5) which is parallel to the inner side (10) of the frame extends along the whole length thereof so that when the mosquito net is attached to the top of the window frame, it partially covers the closed window pane from the upper side of the window frame and over the whole width of the window opening (38). The flange engages the window pane over its whole width so that, when the window pane is partially lowered, said flange remains in engagement therewith and prevents insects from entering the passenger compartment.

Description

Mosquito net for vehicle,

Field of the invention

The present invention is. relates to a mosquito net for window panes for vehicles, in particular for opening windows for heavy goods vehicles or coaches. For vehicle drivers, it is essential to be able to ventilate the passenger compartment of the vehicle, especially when it is necessary to travel long distances and in hot weather. If, to create a slight draft, the driver opens one of the vehicle windows, he is exposed to the penetration into the passenger compartment of flying insects such as mosquitoes, flies, or even wasps . In addition to the inconvenience this may cause the occupants of the vehicle, it can also result in a serious threat to the safety of the driver and therefore a danger to road safety.

State of the art

In order to limit the penetration of insects, it is known to use insecticide bombs, conventional fly catchers or apparatus for spraying insecticide product to be connected to an electrical circuit. The disadvantage of these known means however lies in the fact that they lose their effectiveness when the space in which they are located is not closed. This is precisely the case when an occupant of the vehicle opens a window. Statement of the invention

The invention aims to remedy this drawback by allowing satisfactory ventilation of the passenger compartment while preventing the penetration of insects into the vehicle. To this end, the invention provides a mosquito net for a window pane of a vehicle, delimited by a frame in which a sliding window is provided. The window is arranged to be moved between a first position for closing the opening and a second opening position at least partially opening the opening along the plane formed by the window. The mosquito net includes a frame and at least one canvas supported by the frame. The frame has at least two sides. At least one of the sides is intended to be fixed to the chassis and at least one other side is intended to be turned towards the interior of the bay. The mosquito net according to the invention is remarkable in that at least one bead is provided practically parallel to the abovementioned inner side of the frame on at least one face of the latter. Each bead extends over practically the entire length of the inner side of the frame, so that when the mosquito net is attached to the upper side of the frame, it at least partially covers the closed window from the upper side of the frame and over the entire width of the opening, one of said beads being practically in contact with the glass over practically the entire width thereof and so that when the glass is brought into its second position, the bead remains practically in contact with the glass so prevent insects from entering the vehicle interior from the outside. Thus, thanks to the bead which is provided on the mosquito net according to the invention, it is possible to adapt to vehicles a mosquito net whose canvas retains insects outside the passenger compartment, even when one of the windows of the vehicle which is fitted with a mosquito net, is partially open.

According to an advantageous embodiment of the mosquito net according to the invention, the bead is provided on its contact surface with the opening window of the vehicle with a sealing strip so as to isolate the passenger compartment of the vehicle from the outside. This allows perfect protection of the passenger compartment against the penetration of insects or even dirt.

In particular, the bead has a practically rectangular section, one of the faces being attached to the support frame and the sealing strip being arranged on the opposite face of the bead. This ensures excellent resistance of the bead to the support frame as well as a contact surface with the glass which is enlarged.

According to a very advantageous embodiment of the mosquito net according to the invention, a groove having a determined profile, in particular a U-shaped profile, is provided in the aforementioned opposite face of the bead.

In addition, it is advantageously provided that the aforementioned sealing strip has a profile adapted to the aforementioned groove, said sealing strip consisting of a first and a second portion connecting to each other. The first portion is relatively rigid and the second opposite portion has a relatively high compressibility rate. In particular, the first portion has a central body which is provided with lateral ribs extending longitudinally over practically the entire length of the sealing strip and projecting towards the second portion with a predetermined elasticity. This makes it possible to securely engage the strip by its first portion in the groove by snap-fastening of the latter.

The sealing strip is advantageously multilayer, a first layer consisting of a synthetic material and a second layer of a felted material intended to form the contact surface of the mosquito net with the glass. Thus, a sealing strip perfectly adapted to the groove in the bead can be inserted therein, absolutely reliably by a form connection, in particular by virtue of the oriented lateral ribs acting as stops retaining the sealing strip in the groove.

Additional embodiments of the mosquito net according to the invention are defined in the other sub-claims 9 to 16. Other features and advantages will be described below in a few exemplary embodiments of the mosquito net according to the invention, to using the accompanying drawings.

In general, the present invention relates to a mosquito net to be used in combination with an opening window. This is particularly the case for vehicles, for example trucks and coaches.

Many truck and heavy truck drivers have to travel long distances, sometimes in harsh climatic conditions and are frequently subject to demanding schedules. It is therefore imperative that they can ventilate their cabin in order to improve their comfort and even to combat possible drowsiness to preserve road safety and their own.

FIG. 1 illustrates a mosquito net 1 according to the invention used for this purpose on a window frame 2 of a vehicle, which delimits a bay 38 and in which a window 6 is arranged to slide between a first position for closing the opening 38 and a second at least partial opening position thereof in the plane formed by the window 6.

The mosquito net comprises a canvas forming a grid 3 and a frame 4 supporting the canvas and surrounding it. The shape and dimensions of the frame are adapted to those of the window frame 2 on which the mosquito net 1 is arranged. The thickness of the frame 4 is practically constant. Advantageously, the mosquito net 1 extends practically over the entire width of the opening 38 and is mounted on the upper side of the window frame 2. Furthermore, the mosquito net 1 extends over at least one part of the height of the opening 38. As it appears from FIG. 2, the lower edge of the mosquito net 1 mounted on the window frame 2 determines the maximum extension of the aforementioned second opening position of the window 6 so that the screen retains its effectiveness, the free upper edge of the screen being designated by the reference 18. Thus, to bring fresh air into the vehicle interior, the vehicle window can be opened up to height of the free lower edge 10 of the mosquito net 1 which is turned towards the inside of the opening 38, while preventing the penetration into the passenger compartment of flying insects, such as flies, mosquitoes and wasps, which can considerably annoy the driver of the vehicle.

However, it turns out to be particularly advantageous, as appears from FIG. 2, to provide a bead 5 at the height of the free edge 10 of the mosquito net, which extends practically parallel to the latter on one face of the frame 4 In fact, when the mosquito net is mounted on the window frame 2, there remains a gap between the mosquito net 1 and the window 6 through which insects could pass when the window 6 is open, even partially. To avoid this, the aforementioned bead 5 is arranged so as to extend practically as far as against the window 6 so that the penetration of insects into the passenger compartment is made almost impossible, provided that when the opening of the window, the free edge 18 of the latter does not cross the level of the bead 5, as visible in FIG. 2. The bead is advantageously rigid so as to ensure good mechanical resistance of the latter despite the frequent movements of sliding of the window 6.

Preferably, a bead or a sealing strip 7 is provided on the free end surface 50 of the bead forming contact with the glass so as to provide impeccable insulation of the passenger compartment against the penetration of insects or even impurities, such as road dust. Furthermore, the arrangement of a sealing strip 7 between the rigid bead of the mosquito net and the glass makes it possible to prevent the latter from being damaged by friction between the rigid bead 5 and the glass 6 because of the repeated sliding movements thereof which may cause scratches in the window 6.

The mounting of the mosquito net 1 on the window frame 2 will be described later. Figures 3 and 4 illustrate other types of window frame having a shape other than the rectangular shown in Figure 1. In the case illustrated in Figure 3, the window frame frames two independent panes 8.9 including an 8 is similar to that designated by the reference 6 illustrated in Figure 1, which is sliding. The other window 9 consists of a pivoting deflector. In this case, a practically rectangular mosquito net of the type described above will be used as shown in Figure 3. In the case of Figure 4, there is a single window 10 of substantially trapezoidal shape which is sliding in a window frame 20 of similar shape. In order to ensure the retention of insects thanks to the mosquito net according to the invention, the shape of the latter is adapted as will be seen below in the light of FIG. 7.

In FIG. 5 is shown a mosquito net 1 of substantially rectangular shape, preferably elongated, so as to occupy only part of the bay 38 in height, as it appears from FIG. 1. This allows efficient ventilation of the passenger compartment of the vehicle while ensuring excellent visibility necessary for the driver, at least through the part of the opening 38 not covered by the mosquito net. Another advantage of the elongated shape of the mosquito net extending only over part of the height of the opening 38 lies in the fact that this allows the driver to extend the arm through the window opening if necessary, for example. example during a road check, at customs or road toll booths, or to manually adjust the mirror.

Of course, the circulation of air in the passenger compartment is favored if at least one mosquito net is arranged on two different window frames of the vehicle, preferably on opposite sides of the latter.

Three sides of the screen illustrated in Figure 5 are intended to be mounted on the window frame and one side 10 is free, this being intended to form the extreme limit of lowering of the window so that the screen retains its full efficiency. Preferably, the bead 5 extends only over the exposed part of the mosquito net, that is to say the part corresponding to the bay 38 proper as visible in FIG. 5, so as not to hinder the operation mounting the mosquito net on the frame. The lower and upper longitudinal edges 10, 11 of the screen 1 are adapted respectively to the contours of the window frame 2 and of the free edge 18 of the window 6 in order to ensure an excellent seal when the screen is mounted on the frame 2. Thus , the mosquito net has rounded edges 14, 15 upper corners. At the lower edge 10, rounded 16 and 17 are provided corresponding to the generally rounded corners of vehicle windows. Thus, the window can be lowered until its free edge 18 reaches the lower edge 10 of the mosquito net without the risk of insects passing through the corners of the window 6.

A groove 19 is advantageously provided in the bead 5. The groove 19 extends longitudinally over practically the entire length of the bead 5, preferably centrally with respect thereto. The arrangement in the bead 5 of the advantageously profiled groove 19, for example along a U-shaped profile visible in FIGS. 6 and 8, allows the sealing strip 7 to be accommodated there, which for this purpose has a profile adapted to that of the groove 19. The maintenance in the groove 19 of the sealing strip 7, which is in permanent contact with the window 6 and which is subjected to frequent friction therewith during each opening operation of the glass, is thus ensured.

As can be seen from FIG. 9, the sealing strip 7 advantageously consists of a relatively rigid base portion 21 intended to be clamped in the groove 19 and of a highly compressible crown portion 22, said portion of crown 22 being intended to come into contact with the pane 6. Advantageously, the crown portion 22 has a hollow tubular structure 25 so as to increase the elasticity and to favor the compressibility of this part of the sealing strip 7. It the result is that the latter is not likely to oppose too high a frictional resistance during the operation opening the window 6, while pressing well against it.

The base portion 21, for its part, which has a significantly lower compressibility rate, is full and conforms to the contour of the groove 19. Another profile however proves to be very advantageous. Thus, the base portion 21 comprises a central portion 23 extending over its entire height, to which are attached, on either side, each time at least one longitudinal rib 24 extending along said central portion 23 The ribs 24 are parallel and form a pronounced projection relative to the central part 23. The ribs 29 are oriented towards the crown portion 22 at a determined angle less than 90 ° so as to form a connection of secure shape by snap-fastening. the base portion 21 in the groove 19. In addition, this also facilitates the insertion of the sealing strip 7 in the groove 19. The crown portion 22 is attached to the base portion 21. In addition, the portion crown 22 preferably covers the bead 5 by spreading over it when it is compressed by the window pane 6. Said central part 23 may also have a tubular structure to facilitate bending of the sealing strip 7 to the rounded edges of the bead 5 and therefore the insertion thereof.

The base 21 and top 22 portions of the sealing strip each consist for example of an elastomer or of a rubber which may or may not be identical for each portion 21 and 22. In another known example, the base portion 21 consists of a determined elastomer and the crown portion 22 of the same elastomer but expanded, so as to confer different elastic properties on each portion 21,22. In another exemplary embodiment, the sealing strip 7 is multilayer, a first layer being formed by that described above, a second being applied to the first so as to constitute the contact layer with the window 6. This second layer can be formed for example by nylon bristles or by a felted fabric so as to eliminate any friction between the bead 5 and the window 6. The layers can be fixed for example by gluing. He is at. note that the sealing strip may also consist only of a felted fabric ribbon applied for example by gluing to the free end face 50 of the bead 5. At least one cross member 33 is advantageously provided between the edges longitudinal 10 and 11 of the mosquito net 1 so as to reinforce the rigidity and the resistance to torsion thereof. On the lateral edges 12, 13 and upper longitudinal 11 which are intended to be mounted on the window frame 2, fixing openings 30 are provided so as to allow the passage of fixing means 44 such as screws, as described below.

The support frame 4 of the mosquito net consists for example of a synthetic material giving it a certain lightness. Preferably, the material is transparent, for example Plexiglas ^®. Thus, excellent visibility is ensured even through the support frame 4 itself. This is particularly advantageous in the case of heavy goods vehicles and coaches in particular, since these generally have mirrors extending over the entire height of the window bay 38, therefore also behind the mosquito net, which should therefore not constitute a visual obstacle between the driver and the rear view mirror.

The canvas 3 of the mosquito net is for example metallic and can be fixed to the frame 4 for example by gluing. However, the fabric can also be made of the same material as the support frame 4. The same goes for the bead 5. Thanks to the robustness of the material, security against burglary in the passenger compartment of the vehicle remains substantially identical to the one who. is present when the safety windows are closed, especially if the mosquito net is mounted inside the passenger compartment as mentioned below. Thus, the support frame 2 can be obtained by injection molding in suitable dies. The same goes for the fabric and the bead. It follows that the support frame and / or the bead and / or the canvas of the mosquito net can be made in one piece in whole or in part at a very high rate.

Another exemplary embodiment of the mosquito net according to the invention is illustrated in FIGS. 7 and 8. The shape of the mosquito net is adapted thereto to a window opening 29 of trapezoidal shape as shown in FIG. 4. This mosquito net is remarkable by a projection 32 extending from the screen part proper at an angle so as to be adapted to the shape of the window frame 20 as visible in FIG. 4, so that the effectiveness of the screen in case operation of the trapezoidal window is ensured. It is also possible to still provide, if necessary, a fabric in the aforementioned projecting part 32 extending at least over a part of the length thereof and attached, if necessary, to the fabric 3 of the main part of the mosquito net 1. This allows, if necessary, to increase the ventilation of the passenger compartment.

In the aforementioned exemplary embodiment, a profiled bead 5 is preferably provided on either side of the support frame 4, as is clear from FIG. 8. Because the mosquito net 31 is asymmetrical, this allows to arrange it either on a left or right door, inside or outside the passenger compartment of the vehicle. However, when the mosquito net is symmetrical along a transverse axis as in the example illustrated in FIGS. 1 and 5, a bead 5 on one side of the mosquito net is sufficient as it appears from FIGS. 2 and 6.

Furthermore, the mosquito net according to the invention can also be used in combination with a deflector not shown of known type and used to protect against bad weather, in particular against the penetration of rain into the passenger compartment. The assembly of a mosquito net according to the invention is described below with the aid of FIGS. 1, 2 and 10. As mentioned above, the mosquito net can be mounted on the window frame 2 both inside and outside. '' outside the passenger compartment. Of course, the installation on the inside avoids the clogging of the mosquito net. Before mounting the screen on the vehicle, the sealing strip 7 is pressed against the bead 5 or in the groove 19 thereof, which is intended to be turned towards the window 6. Fixing flanges 40 are inserted by a first end between an elastic band 41, which is conventionally provided in the window frame 2, and the latter. The fixing flanges 40 are maintained by the pressure of the elastic band 41 against the side wall 42 of the window frame 2 and by a particular configuration of the fixing flange which is adapted to the profile of the window frame. This has for example a profile ending in L on the end of which the flange rests with a slight curvature 43 provided transversely practically at the height of the flange. At the opposite end of the flange, an orifice is provided for the passage of the aforementioned fixing means 44 of the mosquito net. Thus, the mosquito net is pressed against the inner edge of the window frame after the fixing flanges 40 have been arranged between the window frame 2 and the elastic band 41. The fixing means 44 are brought by the orifices of the abovementioned flanges, then through the openings 30 of the mosquito net, as it appears in FIG. 3. After tightening the fixing means 44, the mosquito net according to the invention is mounted on the vehicle. The assembly is therefore simple and quick.

It is understood that the scope of the invention is in no way limited to the embodiments described above and that variants of these are to be considered as being included within the framework thereof.

Thus, the mosquito net according to the invention could just as easily be used for horizontally sliding windows in the direction of the longitudinal axis of the vehicle.
