RU2590832C1 - Protective from insects and against overheat clothes (without face mesh) - Google Patents

Abstract

FIELD: personal usage items.

SUBSTANCE: clothing comprises three layers. Outer layer-isolating from penetration of insects layer, which is made of good air-permeable thin, fine-mesh material. Central layer is remote (distancing) layer serving as braces system, which distance outer surface of insulating layer from human body at distance both for insects proboscis or sting, sitting on this surface, and made from mesh-like knitted material, which forming threads are plastic bands to create loops, knots, twisting, bending and other elements of knitted mesh-like material, placing these bands at multiple places with its width in thrust between human body and insulating layer of clothes, that is perpendicular to it or close to it position to form said system of braces. Inner layer is protecting, close to body layer of clothes from thin fine-mesh, good air-permeable, preserving human skin from pain at strong action of remote layer of clothes on it, which is made of good air-permeable thin, fine-mesh material (for example, gauze).

EFFECT: disclosed is clothes protective against insects and against overheat.

Description

The present invention relates to protective clothing and can be used to protect against stinging and blood-sucking insects, as well as from overheating, when working outdoors.

Known protective clothing from stinging and blood-sucking insects clothes:

1. V.D. Lukoyanov, V.N. Pavlenko. Beekeeping equipment, apiary equipment. M .: Agropromizdat, 1988, p. 24.

Clothing has only a layer insulating from the passage of insects themselves through it. But such clothes, worn on a naked body or on light linen, cannot protect against all stinging and blood-sucking insects, since the length of the stings or proboscis penetrating through the material of clothes is many enough to reach the human skin, especially in places where the insulating layer touches this skin. To protect yourself from these insects, you have to put on another protective clothing made of thick material under such protective clothing, which removes (distances) the insects from human skin, or make this clothing from thick material. In hot weather, this leads to overheating of the body, so such clothing that protects from insects due to a significant deterioration in the ventilation of clothing is of little use.

2. Known "Distance clothing protective clothing" according to patent No. 2210965. This clothing is placed between clothing that insulates the insects from penetration through it and the human body. It serves as a system of struts that reliably distance the outer surface of insulating clothing from human skin to a distance inaccessible to the proboscis or sting of an insect sitting on this surface.

This clothing is taken as the closest equivalent. But this clothing itself cannot protect a person from insects; it does not have a layer insulating from the passage of insects.

True, in the description of patent No. 2210965, it is also mentioned that, in order to provide an opportunity to test the “Distant clothing of a protective suit”, satin clothing was used for it as an insulating clothing. It turned out a protective suit against insects. This suit, in addition to its insect-protective property, also slightly reduced the overheating of the human body compared to a single-layer protective suit made of thick material (there was nothing more to compare with at that time).

Protection against overheating of clothing is determined by the quality of ventilation of this clothing. In two-layer clothes, where the spacing layer is the same (knitted from plastic tape), comparative protection against overheating is determined only by comparing the breathability of the insulating layers of these clothes. It is known that the air permeability of dense satin, used as an insulating layer when testing clothes according to patent RU 2210965, is many times lower than the air permeability of a mosquito net, from which insulating layers are made according to application No. 2013109991 and according to this application. Therefore, only two-layer protective clothing with an insulating layer of a mosquito net, according to application No. 2013109991 or according to this application, can be called “Protective clothing from insects and against overheating,” since they have many times better ventilation than the ventilation of “Remote-protective clothing of a protective suit ”Paired with satin insulating clothing.

3. Known "Facial mesh" according to patent RU 2277838, where there are two of the same as in the proposed protective clothing layer. But it achieves a different technical result than in the proposed application. As recorded in this patent: “it is especially important that these protective means interfere with the work of a person as little as possible - they cling less to branches and branches of bushes and trees”. This patent replaced the previously used face net from one layer of a mosquito net (where excellent ventilation was provided for the head and neck of a person), and either hat fields or wire hoops were used to remove its cover from the skin of a person (that is, a wire-frame distance was used) . This made such a front mesh very bulky and inconvenient, although the previous design was better ventilated, i.e. better protected the head and neck of a person from overheating. That is, the technical result to which this patent seeks has nothing to do with the application in question.

And in this patent it is written: “In order not to interfere with the review and breathing, the distance layer is absent opposite the person’s face. Therefore, the front mesh to ensure the distance of the front of the insulating cover from the person’s face has another distance device. This is a face guard in the form of a visor placed on the forehead ... ”

It is such an opening opposite the face in the cover of the facial mesh that is the “window” (let's call it that), where the cover of the facial mesh does not consist of two networks, but one of the insulating ones, which provides the person with the necessary mesh for it - good visibility, breathing (for lungs and human skin) and ventilation. But there are no such essential features in the application in question.

(And in paragraph 24.5.3 (2) of the Regulation ** on the verification of patentability of an application for an invention, it is written:

“An invention is not recognized as follows explicitly from the prior art for a specialist if, during the aforementioned verification, no solutions have been identified that have signs matching his distinctive features, or such solutions are identified, but the influence of these distinctive features on the technical result indicated by the applicant is not confirmed ".

Therefore, due to the mismatch of the essential features specified in the patent RU 2277838 and in the application under consideration, the design proposed by me “Protective from insects and from overheating of clothes” must be recognized as “not following the specialist explicitly from the prior art”).

The aim of the invention is the creation of light, protective from insects and from overheating, as well as not causing pain to a person. This goal was achieved due to the fact that the proposed protective clothing has three layers.

The outer layer of this clothing is insulating from the passage of bloodsucking and stinging insects through it. It is a mesh, well breathable, thin layer.

The middle layer is an extending (spacing) layer, made according to the invention patent No. 2210965 (“Distance clothing of a protective suit”), knitted, which serves as a system of spacers that distance the outer surface of the insulating layer of clothing from human skin for a distance inaccessible to the proboscis or sting of an insect, located on this surface. This extending (spacing) layer is made of a network-like material, the forming threads of which are plastic (for example, polyethylene) tapes. These ribbons, creating loops, knots, twists, bends and other elements of knitted network-like material, always become in many places their width opposite 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. This system of spacers, which plays the role of the thickness of the separating layer, ensures reliable separation of the insect sitting on the outer surface of the insulating layer from the human skin at a distance inaccessible to his proboscis or sting. To obtain an even greater distance, a spreading layer can also be used, but a double layer composed of two layers of net material from a plastic tape. This release layer allows air to pass through very well. As this layer can be used "facade mesh", widely used in construction work. Using the presence of such a reliably distancing, spacing layer, it is proposed that the insulating layer be made of fine air-permeable material, even mosquito nets. These two layers of protective clothing are very light, so under their weight there is no painful effect of hard plastic tapes on the human skin in numerous places of their contact. But painful effects on human skin arise when it is necessary for a person to perform any long and hard work associated with the transfer of power between protective clothing and the human body. For example, during long-term transfer of heavy cargo in a backpack, the load is transferred through the straps of the backpack to a protective suit, which, with the help of numerous short, hard sections of the expanse layer in contact with human skin, painfully transfers this load to the skin of the human body.

The inner - protective layer of protective clothing is designed to eliminate this painful effect of a hard, exposing layer on human skin. It is made in the form of a lining or under the entire expanse layer, or only under its separate places that cause skin pain. In the latter case, only individual pieces of the protective layer are sewn to the separating layer of protective clothing, which reduces the area of the skin covered by this layer, and therefore improves ventilation. This third layer of protective clothing is made of thin fine-mesh material (for example, gauze), it passes air well.

In the proposed protective clothing, where there are three of these layers freely passing through the air, such excellent ventilation is created that provides protection against overheating of the human body.

Of course, the strength of such a thin, well-permeable insulating layer material, in some cases, may be insufficient. Therefore, for such cases, a combination can be used in which the proposed three-layer material of protective clothing is used in protective clothing elements (shirt, pants, mosquito nets, etc.) of protective clothing that are less susceptible to power or only in certain places of these elements - in “ventilation windows” elements of protective clothing. The rest is ordinary, durable, single-layer material. But such a “combination” affects the ventilation of clothes.

Materials for protective clothing from insects and from overheating were purchased in city stores. These clothes were sewn in an ordinary city sewing workshop without any difficulties.
