Description

The invention relates to protective clothing elements and can be used to protect a person from blood-sucking and stinging insects. In particular, it will be widely used to protect beekeepers from bee stings during operation.

Known protective clothing from stinging and blood-sucking insects with elements that provide air exchange [1]. Known protective clothing contains a ventilation element in the form of a system of struts with a thickness exceeding the length of the proboscis or the sting of insects that move the outer surface of the insulating clothing from the human body. Protective clothing is made of a network-like material, the forming threads of which are the specified spacers. The forming threads of the network-like material are ribbons with a thickness significantly less than the width. These tapes are placed in a variety of places with their width in the spacing between the human body and insulating clothing, that is, in a position perpendicular to them or close to that, creating the specified system of struts. Mesh tapes can be made of plastic.

The disadvantage of this known design of clothing is its lack of wear resistance, i.e. ability to resist various mechanical, physico-chemical, biological factors in the process of wearing. The presence of nodal elements in the system of struts creates stress strain concentrators, which causes increased abrasion of clothing, and also creates technological difficulties in manufacturing. Due to the single-layer system of spacers, the protective function, hygroscopicity are reduced, dust permeability is increased. In addition, due to the possible stiffness of the material of the tape, in particular of plastic and its immediate proximity to the human body, operating comfort is reduced. Also, replacing worn areas of clothing is difficult.

Closest to the claimed is the design of ventilation inserts in protective clothing of beekeepers [2]. The known design is made in the form of an insulating system exceeding the length of the proboscis or sting of insects.

An insulating system of a system of elastic elements is made in the form of longitudinal ribs. In particular, ventilation inserts with fins are located both on the upper part of the protective clothing and on the lower predetermined width for the free exit of air into the environment. Thus, the ribs on the one hand create a predetermined gap between the surface of the human body and the fabric of clothing, and on the other, form stable air channels under the clothing for unhindered ventilation. In addition, ventilation inserts in protective clothing, in particular in the area of the armhole, elbow and wrist joint, belt, knee joint and lower leg, are equipped with fabric valves, corrugations, rings. In this case, the shape of the corrugations is supported by the corresponding elastic element, the rings are sewn into the protrusions of the corrugations from the inside, and are assembled on the outside on an elastic band. Such ventilation inserts are controlled by opening the valve, completely or partially blocking the access of air under clothing in cool weather or providing organized natural ventilation when the temperature rises.

The disadvantages of the known design of ventilation inserts are the complexity of the design due to the fact that it is necessary to dock a large number of elements and the accuracy of their location, for example, fixing the ring in the right place, determining the correct size of the diameter of the corrugated corrugations, etc.

insufficient reliability and durability in operation due to the presence of multiplicity in the element base of the structure, which necessitates the connection of elements and creates stress strain concentrators, which causes increased wear of clothing. In addition, the materials used are short-lived, such as rubber and materials for seams when connecting elements;

limited opportunities to increase the ventilation efficiency of protective clothing, as the location of the ventilation inserts is limited;

inconvenience during the operation and storage of protective clothing due to the increased dimension due to the significant protrusion of some elements of the ventilation insert from the base, for example, rings, etc .;

low maintainability due to the need to repair clothes in general;

increased cost of protective clothing in general due to the increased complexity in the manufacture of ventilation inserts.

The objective of the invention is to increase the reliability and durability, ventilation efficiency, ensuring ease of manufacture and repair, ease of use and storage of protective clothing from blood-sucking and stinging insects while reducing its cost.

The problem is solved due to the fact that the ventilation insert of protective clothing from blood-sucking and stinging insects in the form of an insulating system having a thickness exceeding the length of the proboscis or insect sting is made three-layer. In this case, the outer layer and the inner lining-fixing layer are made of mesh material, and the middle layer is made of cells in the form of prisms, the base area of which exceeds the cell area of the mesh of the outer layer.

The main distinguishing feature of the claimed invention is a different form of execution of the insulating system and the characteristic performance of its elements. The implementation of a three-layer insulating system allows you to provide an effective ventilation system on the surface of the human body

- 1 020675 while maintaining the reliability and durability in operation of all protective clothing as a whole. This ensures the protective function of the suit, hygroscopicity, dustproof due to the creation of several levels of protection. In addition, replacing worn items is straightforward.

The implementation of the middle layer of cells in the form of prisms, the base area of which exceeds the cell area of the mesh of the outer layer, provides sufficient functionality even when using materials of small thickness, maximizing ventilation efficiency. At the same time, the ventilation insert has a uniform thickness, it is not difficult to manufacture, and therefore its cost is reduced.

Despite the popularity of the use of mesh material in protective clothing in the inventive ventilation insert, the implementation of the outer and inner lining-fixing layers from it allows to ensure its inextensibility, to ensure comfortable operation due to hygroscopicity.

In FIG. 1 shows a General view in section of the inventive ventilation insert of protective clothing, in FIG. 2 is the same, top view, in section along aa.

The ventilation insert of protective clothing is made of a three-layer insulating system with an inner lining and fixing layer 1, an outer layer 2, and a middle layer 3. The total thickness of the layers exceeds the length of the proboscis or insect sting. In this case, the inner 1 and outer 2 layers are made of mesh material, and the middle layer 3 is made of cells in the form of prisms, for example honeycombs, the base area of which exceeds the cell area of the mesh of the outer layer.

The manufacture of the ventilation insert and its use in protective clothing is as follows. For the manufacture of the insert separately prepare the lining-fixing layer 1, the outer layer 2 and the middle layer 3 of the insulating system. Mesh material is used for layers 1 and 2, while for layer 1 it is desirable to use materials on a natural basis to ensure the comfort of the human body, and for layer 2 it is possible to use small nets made of synthetic material, for example, such as fishing masks, bee hats, etc. Layer 3 may be made of a polymeric material with a wall thickness of approximately 0.1-0.2 mm to form quadrangular or other prisms. Then the layers 1, 3, 2 are successively folded and fixed. In protective clothing, the location of the insert is determined, where it is inserted and sewn. In this case, the ventilation insert can be installed both in new protective clothing during its manufacture, and in the required repair.

The use of the inventive design of the ventilation insert in protective clothing from blood-sucking and stinging insects will improve reliability and durability, ventilation efficiency, ease of manufacture and repair, ease of use and storage of protective clothing from blood-sucking and stinging insects while reducing its cost.
