Description

The invention relates to light industry, and in particular to personal protective equipment for hands from thermal and mechanical damage for work in conditions of limited visibility. The essence of the product is as follows.

Known protective glove (RF patent No. 23237396, A41D 13/08, 2008), which consists of an outer glove and an inner one. The back side and the cuff of the outer glove are made of fireproof textile material. The palm and interdigital inserts of the outer glove are made of polymer-textile material that is resistant to aggressive substances. The back side and cuff of the inner glove are made of composite material. The palm and interdigital inserts of the inner glove are made of cotton material.

The disadvantages of this analogue are that the protective glove is subject to abrasion and rapid wear, and also does not adequately protect fingers from the effects of cutting objects due to the use of materials inferior in resistance to aramid to external influences. Also, the glove does not have a lighting function. This solution does not protect hands above the wrist.

Known resistant to cut gloves (RF patent No. RU 2438535, A41D 19/015, 2012), containing a substrate configured to include four sections for the fingers, the section for the thumb, the palm and the back of the hand, which are made to cover hands of man. The glove is suitable for both the right and left hand. The technical result provided by the claimed group of inventions is easy to wear, mobility for movement of the joint of the hand and each finger, maintaining breathability and flexibility, increased resistance to abrasion and cuts.

The disadvantages of this glove are that the glove does not effectively protect fingers and hands due to the use of materials inferior in resistance to materials based on aramids to external influences: from thermal effects, and there is also no lighting function. There is no arm protection above the wrist.

Known protective glove (RF patent No. 2126643, 1999), designed to protect hands at the time of accidental fire of objects or substances, as well as to protect the hands of workers in hot shops. The inventive protective knitted glove consists of an inner and outer layer. The inner layer is a knitted glove made by weaving the culinary smooth surface of cotton yarn in an all-knitted way. The outer layer is a knitted glove made of chopped-twisted fire-resistant and heat-resistant tohilen yarn and CBM thread. The palm of the outer glove is reinforced with an additional layer of insulating material covering the upper part of the palm and the beginning of the fingers. As an insulating material, an elastic weave knitwear made from milled-twisted tohilen yarn and CBM thread is proposed.

The disadvantages of this glove are the lack of lighting function in the area of the hands and the limited protective surface: the glove does not protect hands above the wrist.

Known glove for welding with a fire-resistant compressible layer of foam-like material (RF patent No. US N 5369806, А41D 13/10, 1993), which protects the welder from heating and burns during welding. The glove contains a leather sheath, inside of which there is an intermediate fire-resistant compressible layer of foam-like material. The inner layer of the glove consists of a felt-like cotton material.

The disadvantages of this glove are insufficient fire protection, which is associated with the use of materials inferior in resistance to aramid to external influences, as well as the high complexity in manufacturing.

Known protective mitten (patent UA No. 55235, 2005), containing a cotton inner and outer layer. One layer is made of a heat-protective material, characterized in that it further comprises a layer of knitted metal mesh, using a thermal protective material of inorganic fiber.

The disadvantage of the glove is the low ergonomics of working with fingers, insufficient hand protection: there is no hand protection above the hands, there is no lighting function

Known protective glove PCT (WO) N 93/05670 A41D 13/10, B 32135/26, which consists of an inner and outer layer. The inner layer in contact with the palm is formed of a material that provides thermal protection and does not irritate the surface of the palm. The outer layer is formed from a material made of heat-resistant flame-retardant polyamide fibers such as Kevlar, Nomex or P.B.I. The bumpy silicone coating on the surface of the palm of the glove is a heat insulator, but does not protect hands from open flame during operation.

The disadvantages of this glove are insufficient fire protection, which is associated with the use of materials inferior to the aramid in resistance to external influences, as well as the high complexity in manufacturing. The surface of the hand is not fully protected, only the brush

The haberdashery product for protection against cuts (RF patent No. 2075957, A41D 13/10, 2004) contains a sheath made of yarn, on the outer surface of which a polymer coating is applied. The synthetic core thread is made on the basis of polyamidobenzimidazole terephthalamide or copolyparaphenylene terephthalamide, or a mixture of copolyparaphenylenetetrafthalamide with an aliphatic polyamide.

The disadvantages of this product is the lack of lighting function. The closest in technical essence is a protective knitted glove and the method of its manufacture (RF patent No. 2586822, IPC A41D 19/015, 2016), intended for use in extreme conditions. The glove protects the wearer's hands from exposure to cutting objects, thermal and electrical effects, from exposure to chemicals, while the glove has moisture repellent properties. The protective knitted glove consists of two layers: an inner and outer glove, interconnected, with a membrane layer between the inner and outer gloves.

In many industries, a person works with his hands. Specialist workers are often exposed to thermal hazards, so hand injuries are common. To ensure the safety of hands from injury, use simple protective equipment - gloves. However, often the use of gloves does not allow to achieve complete protection of the upper limbs, therefore the disadvantage of this glove is insufficient hand protection, which consists in the limited area of the protective surface - only the surface of the hands. Often a specialist has to work in conditions with low visibility, which suggests the presence of additional lighting, but the technical solution of the well-known gloves does not solve the issue of autonomous use in low visibility conditions.

The objective of the present invention is to ensure safe work with human hands: protection from exposure to cutting objects, short-term contact with the flame by creating comprehensive protection of the hands from the shoulders to the fingertips, local autonomous lighting of the brush area, as well as the anatomical design of the details - “lat”.

The problem is solved as follows. The design of the gloves consists of several parts structurally connected with special heat-resistant buttons with an integrally knitted glove-type part made of aramid weaving threads - cooler surface based on aramid yarn with a thickness of 20 tex, a density of 300 g / m ² , the back surface of the brush is made of thin heat-resistant aramid threads with surface treatment with a special composition based on heat-resistant luminescent paint (PRO series), resistant to temperature + 300 ° С, combined with special in configuration and physical co-specification tight mating of folds hands three parts of heat-resistant aramid material with a protective polymer coating improved mechanical strength, covering the shoulder and forearm, a density of 440 g / m ^2, interconnected coupling gripping elements, the envelopes of the flexion portion and arm turns in all joints. The glove-type part is connected to the “lat” -type parts by heat-resistant buttons.
