Description

The utility model relates to shoe production and can be used in the manufacture of safety shoes, more specifically wading boots for hunters and fishermen, intended for walking in deep water and deep snow.

Known insulated boots SU 1583074 with a top made of felt, which consists of one part. In areas corresponding to the front line of the bootleg, toe and heel parts of the boot, a solution is applied to increase the dimensional stability, a preliminary drawing of the front line of the bootleg shafts is carried out with its subsequent molding and fixing by means of a vibro cassette. Then the workpiece is interconnected in the form of a stocking and attach the bottom unit, consisting of a molded cup-shaped sole. Inside the cavity, the sole is made of stiffeners and a nest for placing a gasket that protects the top from abrasion by stiffeners. The disadvantages of this design is the lack of the ability to replace individual parts of the boots as a result of wear or as a result of changing operating conditions, since the bottom assembly is made integral with the felt top; the need for additional operations in the production process: applying a solution to increase form stability, preliminary drawing, molding with fixation using a vibro cassette. Also, boots are not elastic; not adapted to the anatomy of the structure of the human legs (it is not convenient to bend the knee in them); not resistant to alkaline (for walking in a swamp) and oil-petrol-resistant environments when working in sewers, underground utilities, sewers and other aggressive environments.

Known combination boots for hunters and fishermen (patent RU 58307 U) containing a rubber galoshes with a corrugated bottom, characterized in that the bootleg is made of rubber-textile material attached to the rubber halo, rubber ribbons glued and sewn on the connecting seams reinforce the waterproof effect of the boot, the upper leg ends with an attached cuff and is pulled together with a cord, the warming stocking inserted inside consists of a bootleg, on the heel part with a stitched back and a set-in stitch koy.

The disadvantage of these boots is that their assembly is structurally difficult to manufacture, since the boots consist of several parts that need to be attached and pulled together with a cord (i.e. manual production); the boots retain little heat at low sub-zero temperatures, as made of rubber; not elastic; not adapted to the anatomy of the structure of the human legs (it is not convenient to bend the knee in them); not resistant to alkaline (for walking in a swamp) and oil-petrol-resistant environments when working in sewers, underground utilities, sewers and other aggressive environments.

Known Yeti boots [http://e-boots.ru/p6784480-sapogi-jeti.html] and their modification EVA fishing boots [http://e-books.ru/p6380816-rybatskie-sapogi-eva.html]. The boots are made of ethylene wines or acetate (EVA). It is a modern, lightweight material with high shock absorbing properties and elasticity, even at low temperatures. The microporous structure of the EVA material creates an “air gap” and, thus, retains heat. The main advantage of EVA boots over fishing and hunting shoe covers and other similar shoes for harsh conditions is their weight, as well as the ability to maintain sock comfort at temperatures up to -60 ° C. This allows you to use boots from the EVA "Yeti" both with long walking and with a sedentary stay in the cold (near the hole).

Insulation boots EVA. The combined warming insert consists of 7 layers:

1. "Spunbond" - non-woven material, absorbs condensate from the inner surface of the EVA boot.

2. Metallized film to reflect the cold.

3. A layer of synthetic fiber (NTP), contributing to the removal of moisture outside the insulation liner.

4. A second layer of metallized film to reflect heat from the foot back to the foot.

5. A combined layer of natural and artificial materials that absorbs and removes all moisture and condensate.

6. Polyester foam. It has an open mesh structure. It is necessary for removing moisture outside the insulation liner.

7. Knitted lining. Natural material, provides comfort socks, has increased wear resistance. It is treated with an antibacterial solution, which prevents the growth of bacteria in the process of wearing shoes, and therefore the formation of an unpleasant odor.

The upper part of the EVA fishing boots is attached to the belt of the trousers with the help of a latch, thus providing ease of movement. The uniqueness of this model of EVA fishing boots is that it is comfortable and warm to fish in cold water, because The base boot is made of EVA foam, which is characterized by low thermal conductivity, high thermal insulation and shock-absorbing properties.

The disadvantage of these boots is that their assembly is structurally difficult to manufacture, since the boots consist of several parts (pre-knee part of the boot and the upper knee part) that need to be glued (i.e. manual production). Thus, the upper part of the boots is often peeled off. In addition, the boots are not adapted to the anatomy of the structure of the human leg (it is not convenient to bend the knee in them).

Known fishing boots [http://art.shop.by/turizm/56186/Sapogi-bolotnye-rybackie-zhestkij-verh/]. All models of fishing boots are developed on the basis of PVC boots, to which, on modern Italian equipment, a textile top made of vinitol or nylon is attached using high-frequency welding. Additionally, the double-seam technology is applied, which gives the shoe guaranteed strength, wear resistance and tightness. The base boot itself is made by the methods of two-component or three-component casting - using the third additional intermediate layer of the sole made of foamed PVC, which gives the shoe high shock-absorbing, heat-protective and antistatic properties. Of particular importance is the foam layer inside the sole of the boot. Thanks to this layer, the sole acquires orthopedic, shock-absorbing, heat-shielding properties. In these boots, the legs are less tired, the roughness of the road is not felt, and the effect of the cold sole disappears.

Shoes do not lose their elastic properties in a wide temperature range from -40C to + 50C, while all quality and strength characteristics of the shoe are preserved. The disadvantage of these boots is that their assembly is structurally difficult to manufacture, since the boots consist of several parts (the pre-knee part of the boot and the upper knee part) that need to be sewn (i.e. manual production). Thus, the upper part of the boot loses tightness at the junction with the bottom. In addition, the boots are not adapted to the anatomy of the structure of the human leg (it is not convenient to bend the knee in them). The disadvantage is the ingress of water, sand and other debris into the boot with the foot inserted into it; Also, heat is not retained inside the boot. The closest solution is marsh boots [http://e-boots.ru/p4765110-bolotnye-sapogi.html] made of PVC, made by the method of three-color casting, that is, they have a middle layer of foamed polymer in the sole. This layer makes the swamp boot lighter and also provides additional shock absorbing and heat-insulating properties.

The disadvantage of these boots is that their assembly is structurally difficult to manufacture, since the boots consist of several parts (the pre-knee part of the boot and the upper knee part) that need to be sewn (i.e. manual production). Thus, the upper part of the boot loses tightness at the junction with the bottom. In addition, the boots are not adapted to the anatomy of the structure of the human leg (it is not convenient to bend the knee in them). The disadvantage is the ingress of water, sand and other debris into the boot with the foot inserted into it; Also, heat is not retained inside the boot.

The purpose of the utility model is to eliminate the disadvantages inherent in the prototype.

The technical result of the utility model is the best protection against the ingress of water, sand and other debris into the boot when the foot is inserted into it; it also holds heat better inside the boot.

The specified technical result is achieved due to the fact that the boots are marsh, containing a corrugated foot on the sole, made of cellular foam material, characterized in that the sole, bootleg and upper part of the boots are made in the form of a single monolithic structure, as well as in the upper part of the boot along the perimeter fixed elastic material impregnated with water-repellent. The elastic material may be made in the form of rubber. The fastening of the material to the upper part of the boot is preferably done on the outside of the boot by the firmware method.

A loop can be attached to the elastic material.

The elastic material can be selected in width based on the condition that its width is at least half the radius of the upper part of the boot.

On the knee part of the boots in the bend zone of the knee part of the legs, corrugations are preferably made of ribs that are located on the back and front.

Preferably, a spur protrusion is formed on the back of the boots in the area of the sole.

As the cellular foam material, ethylene vinyl acetate or foamed PVC can be used.

The boot part of the boot preferably contains stiffeners made in places of greatest load when walking.

Utility Model Implementation

Wading boots are made with a grooved (11) sole (1) of the feet (see Fig. 3). A distinctive feature of the device is that (see Fig. 1) the sole (1) (see Fig. 3), the shaft (2) and the top of the boots (5) are made in the form of a single molded structure of cellular foam material, which provides the best protection against the ingress of water, sand and other debris into the boot when the foot is inserted into it; it also holds heat better inside the boot. Since the sole, bootleg and upper part of the boots are made in the form of a single monolithic structure, the boot does not have seams, joints, adhesions, joints, and heat transfer through them from the leg to the outside does not occur, which is better than the heat conductivity coefficient. Also, as a result, an integral homogeneous product is formed that does not have seams, joints, adhesions, joints, which provides better protection against the ingress of water, sand and other debris into the boot with the foot inserted into it.

Thus, this product is easy to manufacture, does not require manual labor, and can be produced in an automated way. The same monolithic design of the boots provides an increase in the operational characteristics of the boots, increasing comfort. This is achieved by eliminating the possibility of breaks at the joints or adhesions of various elements in boots. Due to the cushioning properties of the material, the load on the spine when walking is reduced.

In the upper part (5) of the boot, an elastic material (9) impregnated with a water-repellent is fixed around the perimeter.

The elastic material (9) can be made in the form of rubber. The fastening of the material to the upper part of the boot is preferably made from the outside of the boot by the firmware method (10) (see Fig. 1, Fig. 4).

A loop (12) can be fixed to the elastic material (9), which serves to conveniently hold the boots in the hands with one finger (see Fig. 4).

The elastic material (9) can be selected in width based on the condition that its width is at least half the radius of the upper part (5) of the boot. This condition contributes to a stronger fit of the material (9) to the user's leg inside the boot.

The elastic material (9) prevents water, sand and other debris from entering the boot with the foot inserted into it. Elastic material holds and fixes the bootleg by fitting the legs. The elastic material is specially made for this type of product and is impregnated with a special water-repellent substance. Thanks to the elastic material, heat is retained and optimal ventilation inside the boot is also ensured.

Also, the use of foamed material creates a total mass of material that is flexible, holds the temperature and works on the principle of a thermos. The principle of a thermos is achieved due to the material itself, which consists of separate interconnected pores filled with air bubbles (see Fig. 2).

Thus, all this ensures the exclusion of the destruction of the joints between the popliteal and patellar parts and the improvement of tightness, while maintaining the operational characteristics of PVC boots with increased comfort. As the cellular foam material, ethylene vinyl acetate or foamed PVC can be used.

On the knee part of the boots in the bend zone of the knee part of the legs, corrugations of ribs (3, 4) can be made, which are located on the back (4) and front (3) parts. These corrugations provide increased operational characteristics of boots, increased comfort.

The ribs (3, 4) are adapted to the bend of the knee part of the leg. For example, five ribs on the front and two ribs on the back.

A protrusion (spur) (8) can be made on the back of the boots so that it is easier to put on and take off the boots. Spurs (8) provide increased operational characteristics of boots, increased comfort.

Additionally, boots in the boot area may contain stiffeners (6, 7) in the parts of the boots that experience the greatest load when walking. This reduces the load on the legs. Thus, the utility model implements boots that relate to year-round use, in particular to walking on snow, swamps, water barriers, as well as uncomplicated areas. They retain heat at low temperatures up to -45 degrees, retain elasticity at low temperatures (specificity of the material), are resistant to alkaline (walking in a swamp) and oil-petrol-resistant environments when working in sewers, underground utilities, sewers and other aggressive environments.
