Description
A FASTENING APPARATUS FOR INSECT PROTECTION SCREENS
AND/OR SOLAR SCREEN FABRICS
FIELD
The invention relates to a fastening apparatus for insect protection screens, solar screen fabrics or the like on openings, especially for windows or doors.
BACKGROUND
The protection from insects can occur within closed rooms by means of chemical agents with the disadvantage of health impairment and problems with environmental protection and in a constructional manner by fly or mosquito protection nets or screens. Particularly in countries or regions with a relatively high share of natural landscape, protection from insecas has a high relevance in respect of health and economy under respective climatic conditions.
The fastening of the fly screen to openings such as windows or doors poses problems. Often, a fly protection screen is fastened by nails on window or door frames. The disadvantage is in this case that as a result of the punctiform transmission of force, the fl.y screen will tear under loads, nails can only be hammered into wood not into plastic frames and irreversible damage is caused after extracting the nails.
From DE-OS 4128491 a mounting frame for receiving sheeting and screens are known. Four pieces of squared wood are cut in a mitred way at the ends, so that the same can be added to a frame at the corners with the help of mounting squares. The frame can then be fixed to a window frame disposed underneath the same. The fly screen is clamped between the angular part and the outer edge of the frame and thus fastened. The disadvantage is that for fixing the fly screen angular parts need to be screwed onto each side of the frame and there is no tensioning of the fly screen during the clamping and mounting process, so that the same is not held in a taut manner. Moreover, the pieces of squared wood are not resistant to weathering and require a fair amount of work to be invested.
Accordingly, it is the object of the present invention to provide a fastening apparatus that eliminates the aforementioned disadvantages while offering at the same time a simple constructional design.
This object is achieved by a fastening apparatus according to the features of claim 1: Preferable embodiments are the subject matter of the sub-claims.
The present fastening apparatus for insect protection screens, solar screen fabrics or the like consists of two profiled elements, namely an upper and a lower part which are arranged in such a way that they ca:n be joined into a frame-like fastening apparatus by a clamping process.
During the clamping process the fly screen or the protective fabric is clamped between the two profiled elements, which means that they are thus also fastened, and additionally pulled in slightly to the outer side, so that the screen, fabric or net is tensioned automatically. The ends of the profiled element are cut in a mitred manner, so that they can be joined into a blind frame. The lower part is screwed or glued to the window or door frame or fastened by means of hinges as a swivel frame. The upper part is then clipped onto the same by the clamping process.
Preferably, the lower part is arranged in the cross section as a U-profile, with the lower side being glued fixedly to the window or door frame or being screwed on with the help of bores in the lower side, namely the middle leg. The outer leg of the lower part is clearly larger than the inner one and at the end of the outer leg a guide rail is formed by two bridges rectangularly to the inner side, with the lower bridge preferably being approximately twice as long as the upper bridge. At the end of the inner leg an enlargement is formed towards the inner side; so that a snap-in recess is formed. The upper part is arranged in the cross section as an L-shaped profile, with the end of the leg facing the outer side being provided with an offset towards the inner or lower leg. The end of the second leg is provided with an enlargement facing the inner side.
For producing a blind frame or for fastening a fly screen or other fabric/screen, the lower parts, which are cut in a mitred way, are joined into a rectangular (or triangular or trapezoidal) frame and fixed on the window or door frame.
Then the fly screen is placed on the lower part and the offset leg of the upper part is inserted into the guide rail of the lower part. By exerting a force on the upper part, the enlargement of the second leg of the upper part latches into the recess of the inner leg of the lower part.
Simultaneously, the interposed fly screen is clamped and thus fastened. The fly screen is entrained outwardly by the latching process and is thus tautly stretched. By repeating this process at all four sides, the fly screen or the fabric/screen can be fastened completely and stretched completely evenly at the same time. All materials such as aluminium and plastic which are also used in the construction of windows for such profiles can be considered as materials for the upper and lower parts.

BRIEF DESCRIPTION OF THE DRAWINGS
The invention itself both as to organization and method of operation, as well as additional objects and advantages thereof, will become readily apparent from the following detailed description when read in connection with the accompanying drawings:
Fig. 1 shows a cross section of an upper part;
Fig. 2 shows a cross section of a lower part;
Fig. 3 shows a cross section through the fastening apparatus on a window frame; and Fig. 4 shows a view of a fastening apparatus as a blind 2 5 f rame .
DETAILED DESCRIPTION
Fig. 1 shows the upper part 1 of the fastening apparatus 12 in a cross-sectional view. It comprises an L-shaped profile, with one end of the leg 17 comprising an offset 3 facing towards the inner side and the other end of the second leg 18 comprising an enlargement 4 facing towards the outer side.
Fig. 2 shows the lower part 2 of the fastening apparatus l2 in a cross-sectional view. It essentially comprises a U-shaped profile. Bores for screws 14 are provided on the middle leg 8 on the lower side. Two bridges 5, 6 are disposed rectangularly at the end of the outer leg 9, with the upper bridge being half as long as the lower bridge 6. A kind of guide rail 7 is thus formed.
The leg 10, which is at the right-hand side in this case and whose length is approximately one-third of the length of the outer leg 9, is enlarged towards the inner side, thus producing a recess 11 into which the enlargement 4 of the upper part 1 engages during assembly.
Fig. 3 shows a cross-sectional view of the fastening apparatus 12 for a protective screen, fabric or fly screen 15 which is shown in dotted lines and consists of an upper part 1 and a lower part 2. The lower part 2 is fixed at first with the help of adhesive tapes or screws to window frame 13 or is placed in holding parts provided thereon.
Thereafter the fly screen 15 is placed on lower part 2.
The offset leg 17 of the upper part 1 is pushed into the guide rail 7 of the lower part 2, as is shown with the broken line. As a result, the end of a leg 18 of the upper part 1 rests on the end of the inner leg 10 of the lower part 2 (dotted illustration). By applying a pressing force 19 on the upper part 1 the enlargement ~ of the leg 18 latches into the recess 11 of the inner leg 10, as a result of which the upper part 1 and the lower part 2 are mutually connected by bracing within the two components. The fly screen 15 is also fastened by the pressing force between the enlargement 4 and the recess 11. The relevant aspect is that during the latching or snap-in process the fly screen 15 is entrained by the enlargement 4, so that the same is tensioned with bias in the frame. A fly screen or protective screen/fabric can be clamped in a taut way by repeating this process at all four sides of the fastening apparatus 12 of the blind frame 20.
Fig. 4 shows a view of the fastening apparatus 12 as a rectangular blind frame 20 on a window frame 13. By using corner connectors or mitred cuts 16 at the four ends of the fastening apparatus 12, they can be joined into a rectangular (or triangular or trapezoidal) blind frame 20.
The fly screen 15 is fixed completely at all four sides by the four fastening apparatuses 12.
In summary, the present invention allows the simple and cost-effective fastening of fabrics/protective screens or fly screens by using materials known from the construction of window and door frames, with the stretching of the fabric/screen or fly screen being substantially facilitated by the draw-in during the fastening. This ensures taut clamping and helps to achieve low mounting costs. Moreover, a stable construction is obtained which can also be used as an ~~unsupported" insect protection screen in the door area.
Accordingly, while this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications of the illustrative embodiments, as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to this description. It is therefore contemplated that the appended claims will cover any such modifications or embodiments as fall within the scope of the invention.
Fig. 1 shows the upper part 1 of the fastening apparatus 12 in a cross-sectional view. It comprises an L-shaped profile, with one end of the leg 17 comprising an offset 3 facing towards the inner side and the other end of the second leg 18 comprising an enlargement 4 facing towards the outer side.
Fig. 2 shows the lower part 2 of the fastening apparatus l2 in a cross-sectional view. It essentially comprises a U-shaped profile. Bores for screws 14 are provided on the middle leg 8 on the lower side. Two bridges 5, 6 are disposed rectangularly at the end of the outer leg 9, with the upper bridge being half as long as the lower bridge 6. A kind of guide rail 7 is thus formed.
The leg 10, which is at the right-hand side in this case and whose length is approximately one-third of the length of the outer leg 9, is enlarged towards the inner side, thus producing a recess 11 into which the enlargement 4 of the upper part 1 engages during assembly.

Thereafter the fly screen 15 is placed on lower part 2.
The offset leg 17 of the upper part 1 is pushed into the guide rail 7 of the lower part 2, as is shown with the broken line. As a result, the end of a leg 18 of the upper part 1 rests on the end of the inner leg 10 of the lower part 2 (dotted illustration). By applying a pressing force 19 on the upper part 1 the enlargement ~ of the leg 18 latches into the recess 11 of the inner leg 10, as a result of which the upper part 1 and the lower part 2 are mutually connected by bracing within the two components. The fly screen 15 is also fastened by the pressing force between the enlargement 4 and the recess 11. The relevant aspect is that during the latching or snap-in process the fly screen 15 is entrained by the enlargement 4, so that the same is tensioned with bias in the frame. A fly screen or protective screen/fabric can be clamped in a taut way by repeating this process at all four sides of the fastening apparatus 12 of the blind frame 20.
Fig. 4 shows a view of the fastening apparatus 12 as a rectangular blind frame 20 on a window frame 13. By using corner connectors or mitred cuts 16 at the four ends of the fastening apparatus 12, they can be joined into a rectangular (or triangular or trapezoidal) blind frame 20.
The fly screen 15 is fixed completely at all four sides by the four fastening apparatuses 12.
In summary, the present invention allows the simple and cost-effective fastening of fabrics/protective screens or fly screens by using materials known from the construction of window and door frames, with the stretching of the fabric/screen or fly screen being substantially facilitated by the draw-in during the fastening. This ensures taut clamping and helps to achieve low mounting costs. Moreover, a stable construction is obtained which can also be used as an ~~unsupported" insect protection screen in the door area.
Accordingly, while this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications of the illustrative embodiments, as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to this description.
