Description

Fastening system and deinsectization mechanism

Technical Field

The present invention relates to a fastening system comprising one or more fastening devices for mounting a textile article in front of a wall opening. Furthermore, the utility model discloses still relate to a deinsectization mechanism.

Background

A common type of insect control mechanism is a fly net or an insect or mosquito net that is tightened over the door or window opening so that the door or window opening is closed by the insect net.

The insect net is here fastened to the door or window frame from the outside or from the inside by means of a separate frame. As an alternative, it is known to fasten insect nets directly to window frames by means of hook and loop fasteners. Thus, a separate frame is not required.

The individual frames are either prefabricated externally by the supplier depending on the individual dimensions of the respective window or the respective door, or alternatively are cut out and assembled directly on site from standard profiles. The first variant is relatively expensive and the dimensions must be known relatively accurately before production, and experience has shown that: self-cutting frames often have unsatisfactory dimensional stability and are relatively expensive to assemble on site.

In the case of assembly by means of a hook and loop fastener, the hook and loop fastener, which is provided on the back with an adhesive surface, is glued into the frame and cut short there to a corresponding length. The insect net can then be cut to size and pressed onto the hook and loop fastener. This variant can be assembled economically and quickly. However, the disadvantages are: the net can no longer be simply removed or such nets can sometimes tear and may show significant pleats after repeated assembly and disassembly. Keeping sure is: this variant is more suitable than a permanent solution for temporary solutions and is always aesthetically unappealing.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Fig. 1 shows a perspective view of a part of an insect control mechanism with a textile 3, in particular a mosquito net, and an exemplary fastening system comprising a fastening device 1 and a holding device 2.

The fastening system may comprise a plurality and in particular at least four, preferably eight, ten or twelve fastening devices 1 and a corresponding number of retaining devices 2.

The holding device 2 is in this embodiment mounted on the frame 7 in the edge region of the wall opening 4. The wall opening 4 may be, in particular, a window or a door.

The fastening device 1 comprises an upper part 6 and a lower part 5. In the illustrated state, the upper part 6 and the lower part 5 form a form-locking and/or force-locking connection with the intermediate textile 3 and are connected to one another in a snap-fit manner. In other words, the textile product 3 is clamped between the upper part 6 and the lower part 5 as soon as the upper part 6 is connected to the lower part 5 and the upper part 6 and the lower part 5 form a snap-lock connection. An additional form-locking connection between the textile 3 and the fastening device is established by latching elements 8 which extend through the textile 3.

Textile 3 may in particular be an insect net or a mosquito net. Here, the insect net has a mesh size that is so small that insects and especially flies, mosquitoes and gnats cannot climb over or fly the insect net. Alternatively, textile 3 can also be, for example, a filtering nonwoven fabric, a privacy mechanism (sichtutz) or a masking material.

The fastening device 1 may be magnetically connected with the holding device 2. In other words, the fastening device 1 and the holding device 2 are configured such that: a magnetic force-locking connection can be established between the fastening device 1 and the holding device 2, i.e. a closed magnetic circuit is created. The fastening device 1 and the holding device 2 therefore have a magnetic and, if appropriate, magnetizable material, wherein at least the fastening device 1 or the holding device 2 has a magnetic material.

The adhesive surface arranged on the underside of the holding device 2 enables a completely tool-free and damage-free mounting of the holding device 2 on the frame 7 of the wall opening 4. Alternatively, further connecting means, in particular by means of screws or nails, can be considered.

Fig. 2 shows a front view of an exemplary lower part 5 of the fastening device 1. The fastening device 1, in the particular case the lower part 5 of the fastening device 1, comprises at least one magnetic or magnetizable element 16 which can form a magnetic circuit in cooperation with the holding device 2.

In an advantageous embodiment, the element 16 in the fastening device 1 is a permanent magnet. Permanent magnets made of neodymium-iron-boron alloys have proven to be particularly suitable due to the high energy density and the relatively economical price. An associated holding device 2 can accordingly have, for example, a ferromagnetic material.

The lower part 5 has a lower part underside 19, by means of which a base surface can be defined. The lower part 5 is here formed in the base surface as elongated and extends in the longitudinal direction.

Furthermore, the lower part 5 has at least one receptacle 17 for receiving the element 16. The receptacle 17 has an open side and may be referred to as trough-shaped or dish-shaped. The open side of the receiving portion 17 is disposed in the base surface.

The magnetizable element 16, in particular the permanent magnet, can thus be inserted at least partially into the receptacle 17. In particular, the element 16 may slightly protrude from the edge of the receptacle 17 on the open side of the receptacle.

The permanent magnets may be of cuboid-shaped and preferably elongated form, i.e. have a length that is much greater than the width and the height. In order to keep the overall height of the fastening device or fastening system as small as possible, the height of the permanent magnet 16 is constructed smaller than the width, and the width is constructed much smaller than the length.

The lower part 5 has two flange sections 18 of flat design in the longitudinal direction, which are located in front of or behind the receptacles 17 and in the base surface. In each case one latching element 8 is arranged on a lower-part upper side 20a of the flange portion 18 opposite the lower-part lower side 19.

The latching element is a latching head 8. The locking head 8 comprises a tapered shank region 23, which is connected to the flange portion 18. The receptacle 17 also has a lower component top 20b substantially parallel to the lower component top 20a of the flange portion 18.

The flange section 18 has a smaller height than the receptacle 17. The height of the flange section 18 and accordingly its material thickness can advantageously be less than 5mm, in particular less than 3mm and preferably between about 0.5mm and 2.5 mm. It is difficult for insects to be able to climb through the gap created between the textile 3 and the surface (e.g. the wall or the frame 7 surrounding the wall opening 4) on which the holding device 2 is fastened.

Fig. 3 shows a perspective view of the lower part 5. The receptacle 17 with the element 16 is located between the flange sections 18.

The locking head 8 is pointed in its upper region and in the outer surface of the essentially conical or pyramidal design in this case has in each case at least one cutting edge 9 extending from the tip of the locking head 8 as far as the shank region 23.

The edge 24 on the lower component upper side 20 of the lower component 5 extends substantially perpendicularly to the longitudinal direction and thus in the assembled state in the direction of the main tensile load direction of the textile product 3. By means of the essentially flat, taut surface of the lower

component top sides

20a, 20b, the textile 3 is bent (folded) if necessary at the edge 24, but extends only slightly into the surface.

Fig. 4 shows a schematic side view of the lower part 5. The locking head 8 has a cutout 11 extending in the axial direction of the shank region 23. The cutout 11 thus divides the locking head into locking head parts 12 which are independent of one another. The cutouts 11 can extend up to the lower component upper side 20a of the flange portion 18. The latch head parts 12 are elastically deformable in the lever region 23 and are spaced apart from one another, so that the latch head parts 12 can pass through the latch openings 10 of the upper part 6 in the mutually compressed state (see fig. 7 to 10).

Fig. 5 shows a schematic top view of the lower part

upper side

20a, 20b of the lower part 5 from above. Each latch head part 12 has a cutting edge 9. The receptacle 17 extends from the flange section 18 to the flange section 18. The locking head 8, the flange section 18 and the receiving portion 17 can be made in one piece and preferably injection molded.

Fig. 6 shows a schematic bottom view of the lower part underside 19 of the lower part 5, viewed from below. The element 16 is held in the receptacle 17 by means of a holding lug 25. The retaining lugs 25 are arranged on the inner edge of the receptacle 17 in a manner opposite along the longitudinal sides. Alternatively, the holding lugs 25 can also be arranged offset (alternately) in each case. The permanent magnet 16 is configured as a rod (cuboid, elongated).

Fig. 7 shows a perspective view of the upper part 6 of the fastening device 1 corresponding to the lower part 5. The latching opening 10 in the upper part 6 is provided here as: the latching opening 10 can form a co-operating latching connection with the latching head 8 of the lower part 5.

In this embodiment, the latching opening 10 is located coaxially within the associated latching sleeve 13. A bridge 21 extends between the latching sleeves.

Fig. 8 shows a schematic front view of the upper part 6. The latching sleeve 13 has a greater height than the bridge 21. The bridge 21 is connected (in particular integrally) to the catch sleeve 13 in the upper position. The latching sleeve 13 has an end face 22 on the upper component underside of the upper component 6, which end face, in the latched state (latching head 8 latched in latching opening 10 of latching sleeve 13), is in surface contact with a corresponding lower component upper side 20a of the flange portion 18. Here, the end face 22 and the flange section 18 are configured to: the textile 3 located between the end face 22 and the lower component upper side 20a of the flange portion 18 is pressed, so that a tendency to crack or the formation of cracks in the textile 3 (caused by an initial defect (anfangdefekt) of the latch head 8 penetrating the textile 3) is prevented.

Fig. 9 shows a schematic top view of the upper side of the upper part, seen from above. The latch opening 10 has a diameter 15 that is smaller than the inner sleeve diameter 14.

Fig. 10 shows a schematic bottom view of the underside of the upper part 6, viewed from below. The upper component underside of the bridge 21 and the lower component upper side 20b of the receptacle 17 are designed to hold the textile 3 between the bridge and the lower component upper side 20b in a force-locking and/or form-locking manner (in the latched state of the fastening device 1). The latching sleeves 13 can have a flattened area 26 in the direction of the respectively opposite latching sleeve 13. The flattened area 26 is configured to: the flattened region 26 is essentially flush with and parallel to the side 27 of the receptacle 17 in the assembled state of the fastening device 1.

Fig. 11 shows a perspective view of the disinsection mechanism, or more specifically of the wall opening 4 (here a window) closed by means of a textile 3a (here an insect net).

The holding

devices

2a, 2b are mounted in the four corners of the sash 7a, respectively (in pairs) at the corners by means of adhesive connections.

An optional further holding device 2c is provided centrally between the holding devices 2a to 2a, 2b to 2b, depending on the size of the window.

The fastening device 1 is connected to the textile 3a (here an insect net) in a corresponding position of the textile 3a, so that the fastening device 1 forms a magnetic connection with the holding

devices

2a, 2b, 2c and tensions the textile 3a against the window opening 4.

The holding device may be mounted on the inside or on the outside (part) of the periphery of the window opening 4 (or door opening). This depends, for example, on the opening direction, the accessibility and the position (for example the thickness of the elastic seal) in the region between the (window or door) frame and the (window or door) leaf.

As a complement, the screening cloth 3b is held by means of further holding

devices

2a, 2b, 2c mounted directly on the sash frame 7b of the window and fastening devices 1 corresponding to these holding devices.
