Description

Ventilation inserts for clothing used to prevent blood-sucking biting insects

The present invention relates to elements of protective clothing and can be used to protect people from blood-sucking biting insects. In particular, the present invention can be widely used to protect beekeepers from bee stings while they are working.

There are well known garments with air exchange elements that protect against blood-sucking biting insects [1]. There are well known garments with ventilation elements that act as a spacer system, the thickness of which exceeds the length of an insect's beak or stinger and separates the outer surface of the isolation suit from the human body. The protective garment is made from a mesh material having molded strands, and the molded strands have the spacers. Openwork strands are strips that are thicker than wide. The strips are placed in many places to ensure a space between the human body and the barrier clothing, ie perpendicular or close to perpendicular to the human body and the barrier garment to form the spacer system. The strips can be made of plastic mesh material.

A disadvantage of this well-known structure of clothing is its insufficient abrasion resistance, ie its insufficient resistance to various mechanical, physicochemical and biological factors during wear. The nodal elements available in the spacer system induce concentrations of distorting stress, which involves higher wear on the garment and process challenges in manufacture. The single layer spacer system reduces protection and moisture absorption but increases dust permeability. Also, due to the potential stiffness of the strip material (especially plastic) and its proximity to the human body, its handling comfort is reduced. Also, it will be more difficult to replace the frayed part of the garment.

The design of the ventilation insert used in the beekeeper's protective clothing is closest to the one claimed [2]. Known designs are isolation structures that exceed the length of the insect's beak or stinger.

The insulation system of the elastic elements is made in the form of longitudinal ribs. Specifically, ribbed ventilation inserts of a specific width are located in the upper and lower portions of the suit to provide for free ventilation to the outside. Thus, on the one hand, these ribs create a certain gap between the surface of the human body and the fabric of its clothing, and on the other hand, these ribs form constant air channels for unobstructed ventilation. Also, ventilation inserts in protective clothing, especially those located in the areas of the armholes, elbow and ankle joints, waist belt, knee joints and lower parts of the legs, are provided with flaps of cloth, pleats and ring. The form of the pleat is maintained by suitable elastic elements, and the loop is sewn into the inside protrusion of the pleat and gathered elastic on the outside. The same ventilation inserts are adjusted by opening the fabric flaps in cold weather to completely or partially block air from entering under the fabric or to provide natural ventilation of the system as temperatures rise.

Disadvantages of known designs of ventilation inserts are:

-complexity in the implementation of the design, due to the necessity of joining multiple elements and the precise layout of these multiple elements, for example, fixing the rings in place, accurate calculation of the diameter of the gathered elastic rings, corrugations, etc.;

- Insufficient operational reliability and durability due to the multiplicity of elements in the design element base, which requires combining elements and creates stress concentrations that lead to increased wear of the cloth. In addition, the materials applied (such as elastic materials) and materials used to hold the elements together are short-lived;

- limitations on increased ventilation efficiency in protective clothing, as there are fewer places to accommodate ventilation inserts;

- the inconvenience of using and storing the protective suit, due to its higher dimensions caused by the significant protrusion of some elements of the ventilation insert (such as rings, etc.);

- low maintenance due to the necessity of repairing the entire garment;

- The overall high cost of the protective clothing due to the greater labor involved in manufacturing the ventilation insert.

The object of the present invention is to improve the reliability, durability and ventilation efficiency of such garments and to provide for ease of manufacture, use and storage of protective garments for protection against blood-sucking biting insects and to reduce their cost.

Said object has been solved by manufacturing a ventilation insert used in clothing for preventing blood-sucking biting insects as a three-layer insulation system, the thickness of which exceeds the length of the insect's beak or stinger. To this end, the outer layer and the inner liner bonding layer are made of a mesh material, and the middle layer is composed of prismatic cells having a base area greater than that of any cell in the outer mesh layer.

The main characteristics or claimed embodiments are the different embodiments of the isolation system and specific implementations of its elements. In the case of a three-layer isolation system, effective ventilation over the entire surface of the human body can be provided while maintaining the operational reliability and durability of the entire protective suit. In this case, the protective function, moisture absorption and dust resistance of the garment are ensured by more than one level of protection. Moreover, the replacement of worn elements is problem-free. In the case of said intermediate layer made of said prismatic cells, wherein the base area of said prismatic cells is greater than the area of any cell in said outer mesh layer, even when relatively thin materials are used Sufficient functionality is ensured even in the absence of conditions, thus maximizing ventilation efficiency. The ventilation insert has a uniform thickness and there are no manufacturing problems, so its cost is reduced.

While the use of mesh materials for protective garments is well known, by using the material used for the claimed ventilation insert to manufacture the outer and inner liner bonding layers, stretching can be prevented and damage caused by moisture absorption can be prevented. Operating comfort.

Figure 1 shows a schematic view in section of a ventilation insert as claimed in protective clothing, and Figure 2 shows a top view of the ventilation insert taken in section along the line A-A.

Ventilation inserts in protective clothing are made in the form of a three-layer insulation system with an inner liner bonding layer 1 , an outer layer 2 and a middle layer 3 . The total thickness of the layers exceeds the length of the insect's beak or stinger. The inner layer 1 and outer layer 2 are made of mesh material and the middle layer is made of prismatic cells having a base area greater than that of any cell in the outer mesh layer.

Ventilation inserts in protective clothing are manufactured and used in the following manner. The embedded lining bonding layer 1, the outer layer 2 and the middle layer 3 of the isolation system are prepared separately. Mesh material is used for layers 1 and 2, it is desirable to use a material with a natural backing for layer 1 to provide comfort to the body and for layer 2 a synthetic tulle can be used, such as for fishermen's masks, beekeeper's hats wait. Layer 3 may be made of a polymeric material with a wall thickness of about 0.1-0.2 mm, forming rectangular prisms or prisms of other shapes. Layers 1, 3, 2 are then sequentially stacked and bonded together. In protective clothing, the place for the ventilation insert is determined where it will be inserted and sewn in. Ventilation inserts can be embedded in new protective clothing at the time of manufacture or embedded in protective clothing when stitching is required.

Utilizing the desired design of ventilation inserts in garments for preventing blood-sucking biting insects can improve the reliability, durability and ventilation efficiency of such garments and make them easier to manufacture, repair, use and store as well as reduce their cost.
