Abstract

La fenêtre grillagée se compose de segments de bande ou de ruban adhésif (3), possédant une couche auto-collante (6) sur leur verso et une structure de type velcro (9) sur leur recto. Les segments de bande ou de ruban adhésif (3) sont appuyés contre des surfaces polies (7) entourant une ouverture de fenêtre ou de porte. Une coupe (2) de matériau plat en forme de tissu à mailles étroites, en particulier une coupe de tulle grillagé approximativement de la grandeur de l'ouverture de fenêtre ou de porte, qui est tendue ou élargie est ensuite appuyée par ses bords extérieurs contre la surface de type velcro (5) des segments de bande ou de ruban pour former une fermeture libérable de type velcro. Il est alors possible de couper le bord de la coupe de matériau plat (2) qui reste le cas échéant sur les bandes ou rubans adhésifs. Les fils ou les fibres qui forment le matériau plat peuvent avoir une surface supérieure rugueuse, poilue ou pelucheuse. Entre les segments de bande ou de ruban de type velcro et le matériau plat peuvent être disposés des segments de bande ou de ruban de feutre, dont le côté ruban se joint au côté de type velcro et dont le côté opposé possède une couche auto-collante à laquelle sont fixés de manière détachable les bords extérieurs de la coupe de matériau plat.The mesh window is made up of segments of tape or adhesive tape (3), having a self-adhesive layer (6) on their back and a velcro-type structure (9) on their front. The segments of tape or adhesive tape (3) are pressed against polished surfaces (7) surrounding a window or door opening. A cut (2) of flat material in the form of a narrow mesh fabric, in particular a cut of mesh tulle approximately the size of the window or door opening, which is stretched or enlarged is then pressed by its outer edges against the velcro type surface (5) of the tape or ribbon segments to form a releasable velcro type closure. It is then possible to cut the edge of the cut of flat material (2) which remains if necessary on the adhesive tapes or tapes. The threads or fibers which form the flat material may have a rough, hairy or fluffy upper surface. Between the segments of tape or velcro-type tape and the flat material may be arranged segments of tape or felt tape, the tape side of which joins the velcro-type side and the opposite side of which has a self-adhesive layer to which the outer edges of the cut of flat material are detachably attached.

Description

Fly windows, process for its manufacture and the use of a material / for the manufacture of such windows

The innovation relates to a fly window made of a transparent, air-permeable flat material blank, which is stretched on a flat frame, which is held in front of an opening in a wall or wall of a building. The innovation also relates to a method for the production of fly windows and the use of a meter to produce such windows.

Buildings include residential buildings, industrial buildings, halls,

Warehouses, stables, sheds and the like with each

Understood facilities provided with windows and doors,

Flies for which the presence of / T windows to protect against the entry of insects may be of interest.

Known fly windows consist of a wooden frame on which, for. B. a gauze or curtain-like fabric or a corresponding wire mesh is stretched. The wooden frame is nailed together with the covering to the outer surface of a window frame, whereby the associated window in the window frame can be opened to the interior of the room. The gauze-like or curtain-like fabric f or the wire mesh is nailed to the wooden frame or attached with metal clips.

It is a disadvantage of such conventional fly windows that the fabric or the corresponding wire mesh is difficult to replace due to dirt and / or damage. Another disadvantage is that the fly windows as a whole are difficult to remove. A frequent change of the fly window leads to a heavy load on the outer surfaces to which the fly window is nailed.

It is furthermore disadvantageous that the known fly screens, in particular their frames, cannot be produced in a simple manner without manual knowledge and special tools.

Due to the different sizes of the existing windows, there are practically no finished fly windows. This often leads to the fact that especially in warmer seasons, in which one would like to keep the windows, especially of bedrooms, open for a long time, it is necessary to do without them, because there are no fly windows in front of the open windows and they are easy to do do not have it attached.

The task of the innovation is to provide a fly window of the type mentioned, which can be produced in a very short time and with little cost and material without special hand tools, especially by laypersons in the respective required size for any type of window, including round windows can be attached to the desired location without damaging the fly-window-bearing surfaces and that it can be easily replaced in the event of soiling and / or damage, and can also be removed temporarily without any problems and without any stress on the bearing surfaces. If, for example, a curtain-like close-knit fabric or mesh tulle is used as the insect barrier, it should be easily removed after soiling, cleaned in a conventional manner and then used again. The above object is achieved according to the invention with the characterizing features of claim 1 or 9. Designs and further developments after the innovation result from the characteristics of the subclaims. Claims 13 and 14 specify a method for producing a fly window according to the invention.

The innovation is described without any limitation using exemplary embodiments, which are shown schematically in an associated drawing. Herein shows:

1 shows a narrow side view or

Sectional view of a greatly enlarged portion of a first embodiment of a fly window and

Figure 2 is a corresponding view of a second embodiment.

According to the innovation, the frame, on which a narrow-mesh grille is preferably fixed, consists of a double frame with an outer frame part 1 and an inner frame part 2.

The outer frame part 1 consists of individual first stripes 3 made from a plastic material. Of the strips 3, only a section of a strip is shown in the side view in the drawing. The strip 3 has a rear side 4 and a front side 5. The back 4 is z. B. a self-adhesive layer 6, with which the first strips are glued to the outside 7 of a window frame 8. Individual pieces of strip are lined up in such a way that they form a closed frame part which is firmly / glued to the window frame and which surrounds the associated window in front of which the fly window according to the innovation is to be attached. The strip 3 also has a front side 5, which superficially has a continuous burr structure. Such structures are known in the textile sector for the connection of fabric parts. Materials with a velcro-like surface are also under the print "Astrahan fabric" became known.

The velcro-like front side 5 of the strips 3 forms a secure adhesive surface for the inner frame part 2, which is essentially congruent with the outer frame part 1.

The inner frame part 2 also consists of a number of second strips 10 strung together from a further plastic material with an inner side 11 and an outer side 12. The outer side 12 is covered by a self-adhesive layer 13 e.g. formed according to the layer 6 of the strip 3. The inner side 11, on the other hand, is formed by a continuous felt-like layer 14, which mechanically adheres to the Velcro-like surface 5 of the strip 3 with slight pressure.

The hook-shaped fiber ends of the burdock-like surface of the layer 3 engage in the felt-like layer 14 and cling to it. A separation is easily possible only by pulling the strip 10 off the strip 3. A repeated reattachment of the strip 10 to a strip 3 can then be carried out.

To form the inner frame part 2, the individual second strips 10 with the felt-like surface 11 are attached to the Velcro-like surface 5 of the outer frame part.

Subsequently, for example, close-meshed grid tulle, which has previously been cut to match the window area, is applied to the outside 12 of the self-adhesive layer 13, the edge zones of the flat material blank 15 being brought into contact with the outside surface 12 of the second strip 10. The flat material blank 15 is here only as a broken line Line shown. Lattice tulle and corresponding substances adhere to the self-adhesive layer 13 in such a way that they cannot be detached from the layer 13 without damage.

If the flat material blank 15 is larger than required in terms of area, its edge parts projecting beyond the inner and outer frame part are cut off with scissors. The new window window is finished. Surprisingly, a wrinkle-free, tight attachment of the grid tulle on the self-adhesive layer 13 of the strips 10 is no problem even for laypeople.

If after a certain period of use the flat material blank 15 e.g. made of grille is dirty or damaged, the inner frame part 2 can be easily pulled off together with the grille from the outer frame part 1, the outer frame part 1 sticking to the window frame 8. The grille can then be washed together with the individual second strips 10 in a conventional manner without the strips 10 separating from the grille, i.e. without the self-adhesive layer losing its adhesiveness. After washing, the strips 10 are pressed against the frame-fixed strips 10 with the Velcro-like surface.

The first and second strips for forming the outer and inner frame part can have the same or different widths.

It is particularly expedient if the outer frame part 1 has the Velcro-like layer 9 because it is comparatively stiff and, for this reason, cannot be washed as easily as the strips 10 with the slightly flexible felt-like layer 14. Since the outer and the inner frame parts are composed of plastic strips, these also have a high level of adhesiveness when the material is selected appropriately, so that the fly window according to the invention can be used over a longer period of time and, moreover, in accordance with the

Quality of the flat material blank can be washed.

Load-bearing outer surfaces 7, e.g. External surfaces of window frames are practically not claimed by the self-adhesive layers 6 of the strips 3, even if they are removed again. This has the advantage that, according to the innovation, fly windows can also be installed in rented apartments, where approval for the installation of conventional fly windows is not granted because of damage to the outer surfaces carrying the fly windows. Another major advantage of the fly windows according to the innovation is their extremely low frame thickness. The superimposed strips 3 and 10 are so flat overall that they easily find space between the outer surface of window frames and blinds lowered in front of the windows, which is not the case with conventional fly windows.

FIG. 2 shows a narrow side view or sectional view corresponding to FIG. 1 of a second example of innovation, also in a greatly enlarged form. Corresponding parts of FIGS. 1 and 2 are provided with the same reference numerals.

2 consists essentially only of the outer frame part 1 made up of individual strips 3, which, as in the exemplary embodiment according to FIG. 1, have a Velcro structure on the front (5) and a self-adhesive layer 6 on the back (4) , for example, on the outside of a window frame 8 are pressed so that the strips 3 are held self-adhesive on the window frame. In contrast to the exemplary embodiment in FIG. 1, the grille tulle blank 15, the size of the fly window, is pressed with its edges into the Velcro structure of the strips 3. 2, the strips 10 are dispensed with, which have a felt-like structure 14 on the inside and on the outside * to which the grille tulle blank 15 is held. It was found that the felt-like strips 10 for holding the grille tulle blank on the strips 3 with the Velcro structure can also be dispensed with if the grille tulle is designed in such a way that it is adequately held directly on the Velcro structure.

It is clear that the innovation in the embodiment according to FIG. 1 and in the simplified embodiment according to FIG. 2 is not restricted to a specific grille tulle. Instead of a mesh tulle, any other sufficiently close-knit, fabric-like fabric, knitted fabric or braid made of natural or artificial threads or fibers can also consist of metal or plastic.

2, the Velcro strips 3 can first be glued to the outer surface of a window frame. Then e.g. a mesh tulle blank with its edges are pressed into the Velcro structure of the strips. But you can also press the Velcro strips with their Velcro structure side against the edges of the mesh tulle blank and then press the Velcro strips with their self-adhesive outside onto the window frame. For windows of a certain size, e.g. from grille tulle cuts, Velcro strips can already be attached to the edges, the self-adhesive outside of which is protected by a plastic strip that is only removed when the fly window is installed.

* have a self-adhesive layer 12, It can be of advantage if the threads or fibers of the close-meshed scrim have a rough or fluffy or fluffy surface, as a result of which the individual hooks of the burdock structure get caught particularly intensively in the scrim.
