Description

The invention relates to the field of light industry, in particular to the elements of footwear: insoles, liners, orthopedic elements placed inside the footwear to stabilize the foot.

From the "prior art" known orthopedic insole for shoes with high heels, containing the base with the back of the heel and flat front parts, between which there is a curved protrusion to maintain the arch of the foot. The protrusion has such a shape that the points of the upper lines of the sections of the protrusion parallel to the vertical plane passing through the centers of the navicular and cuboid bones of the foot lie at the same height from the lower surface of the base, and the protrusion itself is made of soft elastic material (see RF Patent No. 2336197, Cl. IPC A43B 7/22, published 09/10/1999).

The technical problem is that the shape of the curvilinear protrusion is not able to stabilize the position of the foot in the shoe and prevent its movement towards the toe. The phalanges of the toes go beyond the pads, the heel also moves forward, the foot is not located on the block, all this causes discomfort, an increase in the load on the arch of the foot, excessive pressure on the toes, injury to the epidermis of the toes, bones and joints.

The objective of this utility model is to eliminate the above disadvantages.

The technical result consists in reliable fixation of the foot relative to the shoe, preventing its movement towards the toe with the fingers coming out through the hole in the toe (in the case of open-toed shoes) or compressing the toes of the foot under the action of body weight and gravity in the closed-toe area of the shoe.

The technical result is ensured by the fact that the blocking foot in the shoe from the displacement element contains a flattened base and a protrusion. The upper part of the element is made of cattle leather with a thickness of 0.6-1.3 mm. At the same time, the upper part of the element has a recess in which the roller is placed of porous silicone rubber with a diameter of 7-9 mm, and the protrusion is arcuate, allowing the foot to be fixed under the bases 2, 3, 4 of the fingers at the junction of the bases of the fingers and the foot pad.

In addition, the base is made layered, formed from the flattened edges of the upper element surrounding the protrusion, from a layer of reinforcing mesh and a layer of adhesive material.

In accordance with the particular cases of the execution of the device has the following design features.

For shoes with an open toe, the upper part of the element is made of cattle skin "floter" 1.1-1.3 mm thick.

For shoes with a closed toe, the upper part of the element is made of cattle leather “split” with a thickness of 0.6-0.8 mm.

The roller of porous silicone rubber is made with a diameter of 7-8 mm.

The roller of porous silicone rubber is made with a diameter of 8-9 mm.

The blocking element is made with a shaping on the basis of an oval with a protrusion displaced from the center of the blocking element towards the location of the V metatarsal bone of the foot and spreading along its width in the direction of the junction of the plusus with the phalanges of the fingers.

The blocking element is made 60-70 mm long, 40-50 mm wide, and the length of the projection is 40-50 mm.

The essence of this utility model is illustrated by the following illustrations:

FIG. 1 is a top view of the blocking element;

FIG. 2 is a front view of the blocking element;

The blocking foot in the shoe against displacement element 1 contains a flattened base 2 and a protrusion 3. The upper part of the element 1 is made of leather with a thickness of 0.6-1.3 mm, the upper part of the element has a recess in which the roller of porous silicone rubber with a diameter of 7- 9 mm in order to form a protrusion 3. In this case, the protrusion 3 is arcuate, providing the possibility of fixing the foot pad under the base 2, 3, 4 fingers. The base 2 is made layered, formed from the flattened edges of the upper element surrounding the protrusion 3, from a layer of reinforcing mesh and a layer of adhesive material.

Making leather products with a thickness of less than 0.6 mm will result in critical deformation of the arcuate protrusion 3 of the product with the user's weight and the inability to fulfill its purpose. Making leather products with a thickness of more than 1.3 mm will lead to discomfort due to the formation of calluses and a violation of the epidermis in the area of contact between the foot pad and the arcuate protrusion of the product 3 when wearing shoes. The production of leather goods is due to the fact that it is the most safe and environmentally friendly material for the epidermis, joints and bones of the human foot. Shoes and its elements made of leather, including leather of cattle, due to its softness and elasticity, can take the form of a foot pad at the point of contact with arc-shaped protrusion 3 products. Cattle skin eliminates leg injury during use, has structural rigidity to give the product the required properties declared and required from the product, as well as exceptional wear resistance; has a long service life, a wide palette of colors.

The presence of a roller of porous silicone rubber with a diameter of 7-9 mm, forming an arcuate protrusion, due to the characteristics of the material. Porous silicone - material is elastically deformable. The absence of any adhesion to the lower adhesive layer, passing under it, allows the roller of porous silicone rubber to move forward inside the groove under the influence of the foot pad. The movement of the roller of porous silicone rubber is limited to the limits of stretching the upper leather part of the element. In view of this, a roller of porous silicone rubber will always be in front of the foot pad, and not fall under it, ensuring proper fixation of the foot in the shoe in the desired specific position. The arcuate shape of the protrusion corresponds to the shape of the foot pad under the bases of 2, 3, 4 fingers (the form is also curved). The protrusion is offset to the V metatarsus. Performing a roller with a diameter of less than 7 mm will lead to a deterioration in the performance of the product, namely: the possible slippage of the foot forward, a diameter of more than 9 mm will lead to discomfort and a negative mechanical effect on the toes and on the foot pad.

Since genuine leather is elastic and stretches well, it is not possible to make a product out of it alone. Thus, the base 2 is made layered and consisting of the flattened edges of the upper skin element, surrounding the protrusion 3, of a layer of reinforcing mesh and a layer of adhesive material.

The product is performed with a length of 60-70 mm, a width of 40-50 mm. The length of the protrusion is 40-50 mm.

The blocking element 1 is made with a shaping on the basis of an oval with a protrusion 3 offset from the center of the blocking element 1 towards the location of the V metatarsal bone of the foot and spreading along its width in the direction of the junction with the phalanges of the fingers.

For open shoes, cattle leather (floter) is used, with a thickness of 1.1-1.3 mm. In this case, the roller of porous silicone rubber is made with a diameter of 7-8 mm.

This element, installed in the most open shoes of any size, is absolutely not visually noticeable when worn.

The blocking element is sufficiently soft, comfortable, not traumatic for the epidermis of the legs; does not absorb sweat and does not absorb dust, is easy to clean and clean.

The wide palette of colors of the blocking elements allows the user to choose the element to his own taste to suit the color of the shoe (for example, the color of the insoles, toe, vamp, heel, etc.)

For closed shoes, KRS leather (cattle split) is used, with a thickness of 0.6-0.8 mm.

The blocking element for closed shoes, has a lint structure and an increased diameter of the internal porous element of the roller (8-9 mm). It is characterized by qualities of increased friction with respect to tights, socks, stockings, etc., which additionally with a roller of a blocking element, prevents slipping of the user's feet towards the toe of the shoe and protects the toes from mechanical damage on the inner surface of the shoe.

The blocking element for open and closed shoes has the following general characteristics:

The upper layer is made of cattle leather. At the same time, the floter, 1.1-1.3 mm thick, is used for open shoes, and the split, 0.6-0.8 mm thick, for closed shoes.

The middle layer consists of a mesh of synthetic material (nylon), which gives additional rigidity to the construction of the blocking element, and the bottom layer is made of synthetic rubber glue. The thickness of the lower layer is 200-250 microns. The bottom layer is used to glue the blocking element to the insole of the shoe. Prior to operation, the bottom layer is closed by a separating element.

The inner element is made in the form of a roller made of porous silicone rubber of circular cross section. The diameter of the roller for open shoes is 7-8 mm, the weight of 1 meter from 16 g to 20 g. The diameter of the roller for closed shoes is 8-9 mm, the weight of 1 meter from 20 g to 26 g.

The blocking element is used as follows.

The blocking element is glued to the insole of the shoe with the help of the device installer, based on the user's individual measurements, which he applies to the device installer with the help of any writing accessories (pen, pencil, etc.). Measurements on the installer device are carried out under the condition that the arcuate protrusion 3 of the blocking element 1 gets under the bases of 2,3,4 fingers at the junction of the bases of the fingers and the foot pad.

The arcuate protrusion 3 of the blocking element 1 has a height that is necessary and sufficient for the foot to stop by the protrusion 3 of the blocking element 1 and does not slip forward.

In addition, the arcuate shape of the protrusion 3 repeats the anatomical contour of the foot pad at the base of the toes.

The protrusion 3 of the blocking element 1 has a sufficient degree of elasticity and elasticity in order to keep the foot from moving forward and not injure the epidermis of the legs.

The protrusion 3 of the blocking element 1 adapts to the anatomical features of the foot and takes its shape due to the elastic deformation of materials.

The blocking element 1 does not reduce the internal volume of the footwear for the foot (unlike conventional insoles) due to the fact that it is located in the anatomical fossa on the side of the foot at the base of the toes, which is especially important for closed shoes. The blocking element 1 can be used in shoes with heels, on the platform and on a low sole.

In the process of walking, the foot moves forward along the shoe block towards the toe, until the foot rests against the arched protrusion 3 of the blocking element 1, which stops the movement of the foot forward, the foot slipping forward does not occur, the heel and the toes are inside the shoe shoes.

The product is made as follows.

From the finished cattle skin, rectangular sectors of 10x10 cm in size are cut.

Before being sent to the molding device, every sector is sprayed with water.

In the molding device in the lower part there is a matrix, indicating by its size the future contour of the product. In the upper part of the molding device there is a punch that repeats the contours, volume and dimensions of the arcuate roller of the blocking element. In the manufacture of leather floter for open shoes is placed in the molding device face down.

When lowering the upper part of the molding device towards the matrix, the punch, creating the necessary pressure, in the desired area of the leather sector, forms an arcuate depression in the skin, strictly repeating its shape. The arcuate roller of the blocking element is formed.

The pressure in the forming unit is applied until the skin is completely dry. The skin is treated at a temperature of 70-80 ° C and a pressure of 50-70 atm.

After the molding is completed, the leather sector with the molded arcuate recess is removed from the device and sent to the device, where the molded arcuate recess falls into the groove, repeating its shape, thereby clearly positioning itself in the device for subsequent operations. Further, an element of porous silicone rubber is embedded in the resulting molding.

In the same device on the surface of the leather sector superimposed glue-reinforced adhesive layer with anti-adhesive paper from the outside. At the bottom of the device is a knife that repeats the outer contours of the finished product. The upper working part of the device is absolutely straight.

When lowering the upper part of the device towards the lower part, the necessary pressure is created, which promotes the penetration of the mesh-reinforced adhesive layer deep into the skin structure and the final cutting of the finished blocking element.
