Definitions
- the invention relates to a device for protection against pollen, which consists of a tissue.
- Devices for protection against intrusion of objects in closed spaces are known in many ways.
- insect screens which are designed to prevent insects from entering buildings. They are, for example, self-adhesive, to be directly attached to the window, or they are provided with a subframe, which is then mounted on the window frame or door frame.
- These devices are relatively wide-meshed, so that these devices can not hinder the penetration of pollen, germs or spores.
- allergen reactions in an increasing number of people, it has been for some time now an attempt to develop devices which also offer protection against penetration of pollen whose size is about 10 ⁇ m to 50 ⁇ m.
- devices for filtering the air entering the passenger compartment are known from the automotive industry, in which filters are generally used from multilayer nonwovens.
- the nonwoven fabrics prevent entry of the pollen and the like into the passenger compartment. Due to their structure, however, the nonwoven fabrics are not suitable for use, for example, on door or window openings for pollen protection, since they are not transparent.
- the invention aims to remedy this situation.
- the invention has for its object to provide a device for protection against pollen, which provides an acceptable transparency, high stability and at the same time effective protection against the ingress of pollen.
- this object is achieved in that the fabric is made of a wire and has a mesh size between 25 microns and 80 microns.
- a device for protection against pollen is created on, which has sufficient transparency. At the same time a high degree of retention against the ingress of pollen is achieved by the selected mesh size.
- the use of wire as a fabric provides high stability, so that the device works reliably even on days with high wind speeds on door or window openings and in ventilation systems of motor vehicles.
- the wire has a diameter of 0.03 mm. Due to the wire gauge selected in this way, it is possible to create a mesh with the finest mesh size and thus a perforation that takes into account the size of the pollen.
- the wire is made of stainless steel.
- the use of this material has the advantage that the device is not rusting, so that no impairment of both the visual impression of the device and the functionality occurs even in rain or high humidity.
- the wire consists of an alloy.
- the material properties of the device can be influenced.
- the corrosion properties of the device can be improved, but also the properties in terms of stability or the like.
- the fabric is electrostatically chargeable.
- the electrostatic charge ensures that even pollen, which have a smaller diameter than the mesh size of the tissue are collected by the device. This implies that the mesh size does not have to be reduced in order to repel pollen of smaller diameter, which would impair the transparency as well as the air permeability behavior of the device, but the pollen will nevertheless be collected by the electrostatic charge. It is therefore a very good transparency and air permeability caused at the same time very good filter properties.
- the selected as an exemplary device for protection against pollen is provided for attachment to windows and doors. It consists of a fabric 1.
- the fabric 1 is made of wire. It has a mesh size between 25 microns and 80 microns. Investigations have shown that there is an optimal compromise between transparency of the tissue on the one hand and protection against penetrating pollen on the other hand with a mesh size of 50 ⁇ m. With this mesh size, the airborne pollen relevant for allergy sufferers, such as, for example, hazel, birch, grass, rye and mugwort pollen, are retained with average pore sizes between 15 ⁇ m and 60 ⁇ m.
- the wire has a diameter of 0.03 mm in the exemplary embodiment. Other wire diameters are possible. On the one hand, the transparency of the fabric 1 depends on the diameter of the wire, on the other hand, the processability depends on the diameter. With the selected diameter of 0.03 mm, an optimal compromise between the requirements placed on the fabric is achieved.
- the wire is made of stainless steel, which in particular increases the corrosion resistance of the wire.
- the fabric according to the invention is washable, so that the collected pollen therein after a certain time can be washed out in a simple manner, without having to take the risk of roasting and thus a negative impact on the functionality.
- the wire may also consist of an alloy.
- the addition of nickel in the alloy has proven to be very advantageous in terms of corrosion protection.
- the fabric 1 is electrostatically chargeable.
- the electrostatic chargeability allows the retention of pollen even with a relatively large mesh size. NEN diameter, since the pollen are attracted to their approach to the tissue under the electromagnetic influence. They are then stopped by the tissue and thus effectively prevented from entering the (passenger) room.
- the electrostatic chargeability can be effected by a natural atmospheric charge; but there is also the possibility of an external electrostatic charge to improve the effect of the device targeted.
- the fabric 1 is self-adhesive.
- a self-adhesive film 2 is provided at its outer ends.
- the device can be applied to the window or door frame. By closing the window or the door for a certain duration, a sufficiently high contact pressure is achieved, which allows a secure holding of the tissue to the respective frame.
- a frame 3 which is then mounted on the window or door frame.
- the frame may be formed in one piece or even in several parts, so that the frame and the fabric is mounted only at the site.
- the attachment of the fabric to the frame can either also be done by gluing or by other means of connection, for example by clips.
- the frame itself is made of plastic or metal; Its dimensions depend on the dimensions of the window to be covered or the door to be covered.
- the fabric 1 For mounting the fabric 1 in the ventilation section, for example of a motor vehicle, other fastening elements are generally used, which are adapted to the respective ventilation duct. As a rule, these are screw connections; but immediate insertion into plastic air ducts is also possible. Medical examinations have shown that the device according to the invention has given a retention level of about 98.8% for particles with an average size of 50 ⁇ m. There is thus a high degree of retention, which allows allergy sufferers to flow almost pollen-free air through an open window or an open door in the respective room or in the passenger compartment of a vehicle. This is extremely helpful when the window is open, especially at night, as allergic attacks are avoided, which results in a much more restful sleep for the individual concerned. With regard to the ventilation of passenger compartments, this ensures that, in particular, the driver is spared from allergy attacks caused by pollen, whereby accident prevention is achieved.
