Description

Insect and bird protection nets for industrial buildings and roofs

description

The present invention relates to a protective device for attachment to building openings as protection against intrusion of pests, especially insects. According to the prior art, the building openings are usually protected with internal networks for this purpose.

However, such devices are particularly disadvantageous in building openings in industrial halls, such as skylights, strip lights and louvred fans. Flying with the flaps open Pests such as flies or moths through the flap and against the protective net, they often get out through the flap to the outside. Rather, they often remain in the space between the net and the flap until the flap is closed again. Over time, many pests die in the space between the net and the flap and decompose there. If the pests are decomposed strongly enough, they - together with possibly further dirt particles on the net - can also fall through a close-meshed net. In this way, there is the danger that the decomposed pests get into production.

This is highly disadvantageous especially in food production for hygiene reasons. For example, the corresponding EU-DI N standard explicitly stipulates that every food manufacturer must provide the openings in the hangar with insect screens, which must also be removable. However, the problem here is that the removal of internal nets poses an increased risk that dirt collected thereon, and in particular dead pests collected thereon, may fall into production. An additional problem of the prior art is that the hitherto conventional protection devices are attached, for example, on industrial roofs using a Velcro tape from a rooftop fitter. When assembling, a fitter must lean far from the outside over an open flap in order to attach the protective device all around with the Velcro strip. There is a risk here that fitters can fall through the open flap.

Further problems arise in the prior art from the fact that the nets are often already damaged within two years by UV solar steels and wind and rain partly dissolve the net.

As a further disadvantage has been found that the Velcro tape has often kept too strong in the case of fire in the prior art, so that the fire damper could not open properly in time.

Additionally problematic in prior art networks is that the nets can be easily pinched in the flaps.

It is an object of the present invention to provide an apparatus and a method for overcoming the current disadvantages of the prior art. These objects are achieved according to the invention by the subject matters of the independent patent claims. Advantageous embodiments and further developments are the subject of the dependent claims. A protection device according to the invention for attachment to building openings as protection against intrusion of pests has a close-meshed network and a fastening means with which the protection device can be mounted on an outer surface of a building such that the protection device extends over the building opening. According to the invention, the net has at least one edge, which is stiffened by means of a stiffener. According to the invention, the protective device can be arranged such that the edge extends at an angle α to the outer surface of the building to which the protective device is attached. In particular, the protection device is suitable for building openings of industrial buildings. The opening of the building may, in particular, be skylights, strip lights and louvred ventilators. However, the protective device can also be used, for example, for windows, doors or gates, in particular industrial halls.

In an advantageous embodiment, the protective device is hood-shaped and can in particular be hood-shaped mounted over the building opening. By this is meant that the net extends in a longitudinal direction x of the building opening and in a transverse direction y of the building opening and in a direction z which is perpendicular to x and y. Advantageously, the direction z is perpendicular to the outer surface of the building to which the protection device is attached.

In an advantageous embodiment, the stiffened edge extends substantially in the z-direction. By "substantially", it is to be understood that a deviation of up to about 40 ° is also possible, but the deviation is preferably less than 30 °, more preferably less than 25 ° and particularly preferably less than 20 ° is particularly advantageous for lamellar fans and skylights.

In a likewise advantageous embodiment, in particular for light bands, the stiffened edge extends at an angle a, which is different from 90 °. Preferably, the angle a is also different from 0 °. Preferably, however, the stiffened edge lies in a plane spanned by x and z.

The at least one stiffened edge is preferably stiffened with internal plastic or metal. A plastic profile, a metal strip, a rod or similar is advantageous on the inside of the net. appropriate. Particularly preferably, the stiffener is a rectangular plastic profile. Advantageously, the stiffened edge is the edge extending in the z-direction from an outer surface of a building to which the protection device is attached. Particularly preferably, the stiffening means that this edge is permanently substantially perpendicular to the outer surface of the building after being attached to an outer surface of a building.

In a preferred embodiment, an edge, in particular a corner, is sewn to a plastic film, for example a PVC film. Advantageously, the stiffener is sewn into the plastic film. Preferably, the protective device not only has a stiffened edge, but at least two stiffened edges. Advantageously, these are two mutually parallel edges, in particular around two edges in the z direction. Preferably, there are two side by side and not opposite edges. Particularly preferably, these are the two front edges of the protective device. The term "front" here means the area of the protective device which can be mounted above the "front" area of the building opening, ie above the area at which a device closing the building opening, such as a flap of the building opening, can be pivoted outwards ,

When the flap is opened, the flap in the front area thus has the maximum distance to the outer surface of the building. By comparison, "back" means the opposite area at the building's opening, so the rear area is the area where, depending on the building's opening, there is a hinged door or the door protrudes into the building in an open position.

The stiffened edges are thus preferably in the area in which an open flap protrudes maximally outward. By this stiffening can thus be advantageously achieved that the protective device is not clamped when closing the flap.

Preferably, the network can also be stiffened by darts. In this way it can also be advantageously prevented that the network clamps in the flap.

Advantageously, the stiffened edge or the stiffened edges have at least such a length that a device closing the building opening can be opened outwards. Preferably, the stiffened edge is only slightly longer than the maximum distance between the outer surface and a - in normal operation - maximum open flap. Preferably, the length of the edge is at most 50 cm longer than the maximum distance between the outer surface and a maximum open flap, more preferably at most 30 cm longer, and particularly preferably at most 20 cm longer. Preferably, however, the edge is at least 0.5 cm longer than the maximum distance between the outer surface and a maximum open flap, more preferably at least 1 cm longer, and particularly preferably 2 cm longer. With several stiffened edges, these preferably have the same length. Advantageously, the length of the edge is at least 5 cm, preferably at least 10 cm and particularly preferably at least 15 cm. Advantageously, the length of the edge is at most 150 cm, preferably at most 120 cm and particularly preferably at most 100 cm. In an advantageous embodiment, the protective device has a sealing means. The sealing means is preferably an elastic band, in particular a rubber band. Preferably, the sealing means is sewn to the net and / or integrally connected to the network. In an advantageous embodiment, the sealing means is arranged on the protective device such that it runs completely along the outside. This embodiment is preferred for z. B. skylights and slat fan selected.

In another, likewise advantageous embodiment, the sealing means is attached only on two sides. Preferably, these are the two longitudinal sides which extend from the front region into the rear region. This embodiment is particularly advantageous in light bands. Here, the network with the sealing means can advantageously put sealingly over the curved light band. In a particularly advantageous embodiment, the sealing means projects in the rear region of the protective device to the outside.

In a preferred embodiment, the fastener is a Velcro tape. As a result, the protective device can be easily installed and removed again. However, in another preferred embodiment, the attachment means may also be, for example, an adhesive tape. The fastening means may also be screws, in particular with washers. Advantageously, several types of fasteners are used. Particularly preferred as fasteners a round-running Velcro and screws combined with large washers. The additional screws ensure that the mesh seals even better and gets more hold. Alternatively or additionally, terminal strips can also be used. It may also be provided fastenings such as brackets, eyes, hooks and the like for attaching the protective device. Advantageously, other breakpoints such as click systems, clamp systems, or similar. be used. Prefers These are made of plastic. However, other materials, such as metals, in particular aluminum come into consideration.

Advantageously, a hook or mushroom Velcro be glued around the building opening around, preferably on the Aluhauptprofil z. B. a light band. The fleece Velcro, however, is preferably sewn on the net.

In a further preferred embodiment, the protective device also has at least one roller. In particular, this role can be a castor. Advantageously, this roller is arranged on a device closing the building opening, such as a flap. Preferably, the at least one roller is connected to a frame of a device closing the building opening.

The roller can in particular be arranged on a frame of the flap, for example on a fan frame. Particularly preferably, the at least one roller is arranged such that the roller can be brought into contact with the net, in particular when the flap is open. Advantageously, in this way, the fan frame easier to run in the network without the network can be trapped. Preferably, the axis of rotation of the roller in the y-direction, that is aligned in the transverse direction to the building opening axis. Advantageously, the axis of rotation of the roller is parallel to the portion of the frame which can be pivoted furthest outwardly during an opening movement. In an advantageous embodiment, the protective device has a cable. The cable is preferably fastened to the protective device with a first end section, particularly preferably to the fastening device of the protective device, in particular to a Velcro strip. Particularly preferably, the Velcro strip may have a loop for attaching the rope. Further advantageously, the rope is fastened with a second end portion to a frame of a device closing the building opening.

In this way, it can be ensured that the protective device can be released quickly enough in case of fire. When the flap is removed in the event of fire, the rope pulls on the protective device and in particular the Velcro strip, so that the net is detached from the fastening means and the flap can be opened quickly and completely with the protective device removed.

Advantageously, it may be a steel cable. However, it is also possible a rope of other materials, which are stable enough to ensure removal of the protective device.

Preferably, the close-meshed network of polycarbonate, HDPE, fiberglass, linen material, steel mesh or algae fabric exist. Particularly preferably, the network is made of HDPE. Advantageously, the network is elastic.

In particular, nets with more than 100 mesh / m are to be understood as dense, preferably of more than 200 mesh / m and particularly preferably of more than 400 mesh / m.

In a preferred embodiment, the dense mesh is wind resistant and storm resistant. Advantageously, the network serves as a windscreen network. For this purpose, it preferably has a weight of at least 100 g / m ² , more preferably a weight of at least 120 g / m ² and particularly preferably a weight of at least 140 g / m ² .

Advantageously, the network is also rotting resistant. This can be achieved in particular by the use of HDPE.

Advantageously, the tensile strength is gem. DIN 53857 more than 200 N, preferably more than 300 N and more preferably more than 450 N. Preferably, the elongation at break is gem. DIN 53857 more than 15%, preferably more than 25% and particularly preferably more than 30%. Advantageously, the density at 23 ° C acc. DIN 53479 more than 0.5 g / cm ³ , preferably more than 0.7 g / cm ³ and more preferably more than 0.9 g / cm ³ . Nevertheless, to ensure a sufficient exchange of air, the air permeability acc. ASTM D 737 advantageously more than 150 cm ³ / cm ² , preferably more than 200 cm ³ / cm ² and particularly preferably more than 250 cm ³ / cm ² . Advantageously, the network is UV-stabilized and therefore stable to UV radiation. Particularly preferably, the sewing thread is UV-stabilized. Preferably, the protective device is preserved in this way for three to four years. In a further preferred embodiment, the network has a shading value of at least 40%, preferably at least 50% and particularly preferably at least 60%. For example, a particularly preferred mesh may also have a shading value of 75%. Shading values of approx. 60% are achieved, for example, by white nets. Shading values of more than 60% can, for example, be achieved by using no white but colored nets. As a network color z. B.

be chosen black or orange.

In this way, the protective device particularly preferably also protects the underlying materials, in particular overhead flaps or skylight shells. These usually lose the plasticizer contained in the shells and flaps after approx. 15 years. Since these are protected by the protective device, they have a longer dwell time and UV solar safety.

In an advantageous embodiment, the net is again non-destructively removable after attachment to the outer surface of a building. For example, the net with a sewn-on Velcro tape is non-destructively removable while a hook or mushroom tape remains on the outside of the building.

Advantageously, the network is washable. Preferably, it is washable with cold soapy water. As an additional advantage, the present invention has shown that the net must be washed less frequently than in the prior art. Due to the fact that the net can be mounted on the outside over the building opening, the net partially cleans itself due to rain and wind. This effect is reinforced by the stiffened edges, because this leads to a reduced wrinkling of the net. The self-cleaning ability of the network is increased in this way.

An advantageous network has a high resistance to solvents, in particular up to 40 ° C, preferably up to 50 ° C and particularly preferably up to 60 ° C. In a preferred embodiment, the mesh has a length of more than 0.05 m, preferably more than 0.08 m, and more preferably more than 0.1 m. Preferably, the net has a length of less than 150 m, more preferably less than 120 m, and most preferably less than 100 m. Advantageously, the net has a width of more than 0.05 m, preferably more than 0.08 m and particularly preferably more than 0.1 m. Advantageously, the net has a width of less than 150 m, preferably less than 100 m, and more preferably less than 50 m.

In an advantageous embodiment, the sealing means has a diameter of more than 1 mm, preferably more than 1, 5 mm and particularly preferably more than 2 mm. Advantageously, the sealing means has a diameter of less than 100 mm, preferably less than 70 mm and particularly preferably less than 50 mm. The sealant is preferably longer than 0.1 m, more preferably longer than 0.15 m, and particularly preferably longer than 0.2 m. Advantageously, the sealing means is shorter than 5000 m, preferably shorter than 1000 m and particularly preferably shorter than 500 m.

Advantageously, the protection device also serves as protection against hail penetration.

Advantageously, the net can be printed, for example as an advertising banner or as a wallcovering, and in particular can be printed in four colors.

The present invention is further directed to a method of protecting building openings from pest infestation, in which a protective device having a close mesh is attached to the exterior surface of a building such that the protection device extends over the building opening.

According to the invention, in a first step, the protection device is pulled by a user from outside over the building opening, in a second step the protection device is fastened to the outside surface of the building with a fastening means and in a third step the protection device is pulled taut by means of a sealing means.

In this case, the device described is set up in particular and provided for carrying out this described method, ie that all the features implemented for the device described above are also disclosed for the method described here, and vice versa. Particularly preferably, the protection device is first attached with a Velcro strip on the outer surface of the building. In this way, the net is already held by the Velcro tape during further assembly.

Advantageously, the sealing means, in particular a rubber band pulled tight from behind, so that it seals against critters.

Preferably, the protective device is then attached with screws with large BeilagScheiben so that the network better seals and gets more support. Preferably, these screws are attached only in the rear area, but not in the front area. Otherwise, a rapid removal of the protection device in case of fire is not guaranteed.
