Description

The present invention relates to protective clothing from blood-sucking and stinging insects or from adverse weather conditions.

The purpose of the invention is to facilitate, reduce the cost of a protective suit and provide more comfortable conditions for the person wearing this suit.

Known suit for US patent No. 2344811, 1944, adopted as a prototype. This suit has insulating clothing (insulating clothing) that insects against penetration through insects, to which harnesses (for example, felt, cotton, etc.) are attached (sewn, glued, etc.), placed in two mutually intersecting directions. Harnesses are struts between the body and insulating clothing, providing distance (distance) to the outer surface of the insulating clothing, which may be an insect, from the body to a distance that protects the body from the proboscis or sting of this insect. Harnesses create a net-like spacing layer of a protective suit.

The disadvantages of such a suit are: a large weight of the suit; the dull walls of the cells of the spacing layer formed by bundles prevent air circulation along this layer; the fastening of insulating clothes with integral braids of the spacing layer between them makes the protective suit too rigid, making it difficult for a person to move; It is heavy, difficult to manufacture and operate.

Parallel harnesses in this prototype are placed with each other at an interval at which, although there are no struts, due to some stiffness of the material of the insulating clothing, its sufficient distance is ensured. But, if the spacing of protective clothing is provided at such an interval between the spacers, then instead of solid harnesses, it is enough to install separate point spacers with the same (or slightly smaller) distance that ensures the spacing between them. Point spacers are spacers having a minimum area of contact with the human body, determined by technological and economic capabilities. These are volume elements.

Therefore, in order to eliminate these disadvantages of the prototype, a protective suit is proposed in which the distance (distance) of the insulating clothing from the body is provided by a system of individual point elements - spacers on the inner surface of this insulating clothing. The spacer system creates a spacing layer of the suit between the human body and the inner surface of the insulating clothing, which provides air circulation in this layer (which point spacers almost do not interfere with) and other comfortable conditions for the person. The material consumption for such spacers is many times less than for harnesses, which reduces the weight and cost of the protective suit. Point spacers almost do not block air access to the human body. Not directly connected, they almost do not increase the stiffness of insulating clothing.

Spacers can be made in the manufacture of the material of this garment, for example, in the form of local nodular or looped formations on its surface (such as a “boucle”). They can also be made in the form of separate point volumetric elements attached (glued, welded, etc.) to the material of insulating clothing. For example, the simplest point spacers are spacers in the form of drops of plastic, deposited on the surface of the material of insulating clothing, welded and frozen on it. Mechanized application of such spacers is straightforward. There may be other types of struts.

The protective suit, designed to protect against stinging and blood-sucking insects, has insulating clothing with good air conductivity, and the spacer system, which forms the spacing layer of the suit, removes insulating clothing from the human body for a distance inaccessible to the proboscis or sting of the insect on the outer surface this clothes. The protection of humans from stinging and blood-sucking insects is mainly needed in the warm and hot season, when the number of insects increases many times. Therefore, protective clothing should be lightweight and have good air conductivity. Good air conductivity of insulating clothing improves the removal of heated and humidified air from the spacing layer (from the human body) to the atmosphere and the supply of cool and dry air from the atmosphere to the spacing layer (to the human body). It can be ensured by the manufacture of insulating clothing, in whole or in part, from insect-resistant mesh, durable, wear-resistant and flexible. Such a protective suit is the most promising.

The protective suit, designed to protect from adverse weather conditions, has clothing that is insulated from rain and wind, made of waterproof material, and its spacer system distances (removes) the insulating clothing from the human body by a distance that eliminates the possibility of the inside of the insulating clothing moistened with condensate from touching the body of a person or other clothing placed closer to the body of a person.

To protect against rain and wind, insulating clothing is made of waterproof material. But on the inner surface of such clothing, cooled by adverse weather conditions, water condenses in large quantities. In the proposed protective suit, this condensate is distant from the body by spacers, which also provide air circulation in the air-tight spacing layer. The circulation of air with the exit of heated and humid air and the entrance of a cool and drier protective suit through the ends (its floors, sleeves, gates) creates the conditions for the evaporation of condensate and the removal of moisture vapor from the spacer layer. For more intensive air exchange of the spacer layer of this suit with the atmosphere, special ventilation openings in insulating clothing can be used, protected by pockets or visors from the penetration of rain drops.
