Abstract

A Device for protecting a light and ventilation opening, such as door, window or the like., Against insects includes a network that fits the to be protected Light and ventilation opening dimensioned is. The pre-dimensioned net is by means of a Velcro connection stretched and held, the Velcro configured in such a way is that at the network track at least in a predetermined surface area at least a portion of one of the two elements of the Velcro connection is arranged. The arranged on the network element of the Velcro connection may be both the hook tape or the nonwoven tape.

Description

The The invention relates to a device for protecting a light and ventilation opening, like Door window or the like, against insects, with a netting that matches the Light and ventilation opening dimensioned is.

It Devices of the aforementioned type are known in which a tailored net web is looped with hook bands whose back surfaces self-adhesive Have properties. This is the hook tape with a surface of a Fastening of a window frame of a window or door glued. The net can be glued to its edge areas against it Hook tape pressed be, with the net stitches of the network or the mesh fabric with the hooks of the hook tape. The resulting in the window or door opening stretched held net track prevents the ingress of insects when open Windows, for example in a building interior.

If to keep the meshes of the net web on the hook of the hook tape, that must be Tissue for the grid is relatively thin so that it remains sufficiently flexible and easily deformable, because only then is it possible from the pressure against the hook side of the hook tape a Velcro connection produce. It should be strong enough to withstand the burdens, which from clamping forces the network track and result from wind attack forces, resists.

It It has been shown that the adhesive properties of the known Velcro connections clearly for network tracks limited are. Areas over one square meter are no longer of the hook band especially in wind conditions end to hold because the holding forces overcome the Velcro connection between hook tape and network relatively quickly are.

Of the Invention is based on the object, a device of the aforementioned Genus to improve so that the network also with a Velcro connection securely and permanently to window or door frames is kept stretched out.

These Task is inventively by the Characteristics of the protection claim 1 solved.

further developments and advantageous embodiments will be apparent from the features the dependent claims.

Thereby, that attached to the network of one of the elements of Velcro connection is while the respective other element, as previously known, on the frame a window or a door is, the holding force of the Velcro used is essential higher than the one, which with the known Velcro connection, in which one their elements is realized by the network itself, achieved becomes.

The Netzbahn can be stretched so tight with advantage that a flaps does not occur in wind attack and also in optical terms perfect fit of the network in the covered or protected Window or door opening given is.

The Both elements of a Velcro connection are the hook tape and the Fleece band. The nonwoven tape can also be referred to as a loop tape.

At the respective surface areas the network track, in particular their edge areas, both a section or several sections of the nonwoven or be arranged also the hook tape. Which of the elements of a Velcro connection Finally, attached to the grid, plays for the strength and holding force of Velcro no matter. Is however the fleece or Velcro tape arranged on the network track, the network can be relatively easy and uncomplicated roll up, what with an arrangement of a relatively stiff hook tape on the network would not be the case.

It is possible, too, Hook tape and fleece tape as a verklettete unit at the Network track to order. The tailored, on the respective window or the respective door sized piece of a Netzbahn comes with a unit of the respective intended elements the Velcro connection equipped and delivered at the respective place of use of the device. The Unit made of hook tape and non-woven tape can be easily separated again, wherein each of the network element separate element, the hook band or the nonwoven tape, depending on which element is arranged on the net web remains, to the associated frame part of a window or a Door attached becomes.

each Unit of interlaced fleece and hook tape, is thus one piece or a portion of predetermined length of a corresponding band.

The elements of the hook-and-loop fastener have an adhesive layer on their element sides, which have turned away from one another in the clamped position. This has the advantage that the respective elements of the Velcro connection can be glued to the network track and the respective other element with the frame of the window or the door on which the network path is to be kept relaxed. With particular advantage, the adhesive layer of a first element of the Velcro connection, namely the element of the Velcro connection, which is to be connected to the net web, formed from an activatable adhesive. An activatable adhesive may, for. Example, be an acrylic adhesive with which the back of the element of the Velcro connection, which applies to connect it to the network web, is coated. Such an acrylic adhesive is activated z. B. by short-term heating. It then becomes soft and the bonding takes place with the individual meshes of the net web. After cooling of the adhesive mesh and adhesive backing of the respective element of the Velcro connection are interconnected. The fabric of the net web remains mobile without breaking. Despite the open-pore structure, sticky mass does not escape from the side of the fabric which faces away from the attached element.

The Activation of the adhesive or bonding of the element of the Velcro connection with the surface the net track can also be realized by an impulse welding method, which also uses a combination of heat and pressure. Also, a high-frequency welding technology is quite possible.

The second element of the Velcro fastener has on its back an active adhesive. It therefore has a self-adhesive Move, which is already adhesive, especially at room temperature.

The made of this active adhesive adhesive layer is with a detachable Protective film covered. After removing the protective film, the element the Velcro connection, for example, the hook tape on the fixed frame a window or a door be attached. Of course it is also possible a hook tape of the type described above on a frame made of plastic, To raise aluminum or wood profiles, then to stringing is provided with a network track, and mounted in front of a window opening can be. As soon as the part equipped with the contrary element of the Velcro connection the grid, for example, with his fleece band on the window or on the separate frame located hook tape is pressed, is the window or the door insect proof.

at the device according to the invention has the network web on a network whose net threads each have an inner thread core in an outer core sheath. Particularly advantageous is a net thread of fiberglass, whereby the Net web highly tear-resistant is and thus high clamping forces can be generated in the network. The core serving is with advantage a PVC jacket.

Of course you can too other materials, such. B. polyester fibers with sheath PVC or polyethylene are used. Decisive, it is that the net threads for the Netzbahn consist of two components, a carrier substance as a thread core with a sheath as a core sheath, whose materials are chosen are that the sheath below the melting point of the vehicle already melts. This facilitates the welding of the network track with sections of others Netzbahnen, but also connecting the network track with the element the Velcro connection, which on its back an activatable Adhesive has, for example, a hot melt adhesive, by Heating becomes soft.

One embodiment of the invention, from which further inventive features arise is shown in the drawing.

It demonstrate:
