Description

The invention relates to items of protective clothing and can be used to protect humans against bloodsucking and stinging insects. In particular, it will be widely used in protecting beekeepers against bee bites during work.

It is known protective clothing against blood-sucking insects and żądlącym elements provide _one cymi ^one air exchange. Known protective clothing includes a ventilation element in the form of a system of struts with a thickness exceeding the length of the proboscis or insect sting, separating the outer surface of the insulating clothing from the human body. The protective clothing is made of a mesh-like material whose threads constitute the indicated spacers. The threads making up the mesh-like material are tapes with a thickness much less than their width. These tapes are inserted at multiple locations along their width into the spaces between the human body and the insulating garment, that is, perpendicular to or close to these spaces, forming the indicated spacer system. The webs of the mesh-like material may be made of plastic.

A shortcoming of this known garment construction is its inadequate wear resistance, i.e. the ability not to succumb to various mechanical, physico-chemical or biological factors when worn. The presence of nodal elements in the spacer system creates deformation stress concentrators, which causes increased abrasion of the garment, and also creates technological difficulties in production. Due to the single-layer nature of the spacer system, the protective function is lowered, hygroscopicity and the permeability of dust (dust) is increased. In addition, due to the possible hardness of the material of the belt, in particular plastic, and its proximity to the human body, the comfort of use is reduced. Also, the replacement of damaged parts of clothing is difficult.

The closest to the reported one is the construction of ventilation inserts in the protective clothing of ₂ beekeepers ² . The known structure is made of an insulating system, exceeding the length of a proboscis or insect's sting.

The insulating system, made of a system of elastic elements, is made in the form of longitudinal ribs. Among other things, ventilation inserts with ribs are placed both in the upper part of the protective clothing and in the lower part at a fixed width for free air discharge into the surrounding environment. In this way, the ribs on the one hand create a predetermined gap between the surface of the human body and the fabric of the garment, and on the other hand form permanent air channels under the garment to facilitate ventilation. In addition, ventilation inserts in protective clothing, especially in the area of the cut, elbow and radiocarpal joints, waist, knee joint and lower part of the shin, are equipped with fabric valves, folds, rings. Moreover, the shape of the folds is held by an elastic element, the rings are sewn into the projections of the folds on the inside, and on the outside they are gathered with an elastic band. Such ventilation inserts are regulated by the opening of the valve, fully or partially closing the access of air under the clothes in cold weather or providing organized natural ventilation at higher temperatures.

The shortcomings of the known design of ventilation inserts are:

• the difficulty of constructing a construction due to the fact that it is necessary to touch together a large number of elements and the accuracy of their placement, for example, fixing the ring in the right place, determining the correct diameter, collecting a fold with an elastic band, etc.;

• insufficient reliability and durability in operation due to the existence of a variety of basic elements of the structure, which makes it necessary to connect the elements and creates deformation stress concentrators, which causes increased wear of the garment, moreover, the materials used are not durable, for example rubber and seam materials at the joint of elements;

• limitation of the possibility of increasing the ventilation efficiency of protective clothing, as the places to place ventilation inserts are limited;

• inconvenience during the use and storage of protective clothing due to the large size caused by significant protruding from the base of some elements of the ventilation insert, for example rings, etc.;

Low level of repairability, due to the need to repair the garment as a whole;

• increased cost of clothing, as generally the implementation of ventilation inserts is very labor-intensive.

The aim of the invention is to improve the reliability and durability, ventilation efficiency, ease of manufacture and repair, and convenience during the use and storage of protective clothing against bloodsucking and stinging insects, while reducing its price.

The aim was achieved due to the fact that the ventilation insert of the protective clothing against bloodsucking and stinging insects in the form of an insulating system having a thickness exceeding the length of the proboscis or insect stings is made of three layers. Moreover, the outer layer and the inner layer are made of mesh material, and the middle layer is made of prismatic meshes, the base area of which is larger than the mesh area of the outer layer.

The main feature that distinguishes the proposed invention is a different way of making the insulation system and the performance characteristics of its components. The implementation of the insulating system as a three-layer system allows to ensure an effective ventilation system on the surface of the human body while maintaining the reliability and durability of all protective clothing in general. In addition, the protective function of the garment is ensured, hygroscopicity and no dust permeability, thanks to the creation of several levels of protection. Moreover, the replacement of worn out elements is not difficult.

The fact that the middle layer is made of prism-shaped meshes, the base area of which is larger than the mesh surface of the outer layer, ensures sufficient functionality even with the use of thin materials, maximizing the efficiency of ventilation. In addition, the ventilation insert has a uniform thickness, does not cause difficulties in production, and thus its price is reduced.

Despite the fact that the use of mesh material in protective clothing is known, in the reported ventilation insert, making it of the outer and inner backing-fixing layers makes it possible to render it non-stretchable and to provide comfort during use due to hygroscopicity.

Fig. 1 shows a cross-sectional view of the claimed ventilation insert for protective clothing, and Fig. 2 shows the same, top view, section A-A.

The ventilation insert of the protective clothing is made of a three-layer insulating system with an inner backing-fixing layer 1, an outer layer 2, a middle layer 3. The total thickness of the layers exceeds the length of the proboscis or insect sting. Moreover, the inner backing layer 1 and the outer layer 2 are made of a mesh material, and the middle layer 3 is made of slice-like prismatic meshes, the base area of which is larger than the mesh surface of the outer layer.

The implementation of the ventilation insert and its use in protective clothing is carried out as follows. For the production of the insert, the inner backing-fixing layer 1, the outer layer 2 and the middle layer 3 of the insulation system are separately produced. For layers 1 and 2, mesh material is used, moreover, for layer 1 it is recommended to use materials on a natural matrix to ensure the comfort of the human body, and for layer 2 it is possible to use fine nets made of synthetic material, for example, such as in fishing masks, caps beekeeping and others. Layer 3 can be made of a polymer material with a thickness of about 0.1-0.2 mm to form quadrilateral or other prisms. Then layers 1, 3, 2 are successively folded and joined. Protective clothing is defined as the place of insertion into which it is inserted and sewn. In addition, the ventilation insert can be inserted both into new garments during their production, and in those that require repair.

The use of the reported design of the ventilation insert in protective clothing against sucking and blood-sucking insects will improve the reliability and durability, the effectiveness of ventilation, ensure ease of production and repair, and convenience in the use and storage of protective clothing against sucking and blood-sucking insects, while reducing its price.
