Description

 The invention relates to the shoe industry and may find application in the manufacture of footwear, both for children and adults.

 Modern shoes are classified according to the following criteria: purpose, type, material, construction of the top or bottom blank, method of fastening the top and bottom parts, manufacturing method. According to materials, shoes are mainly divided into leather and shoes made of textile materials. Textile materials for shoes include fabrics, non-woven and knitted fabrics, etc. [1].

 Known reflective fabric and product comprising a reflective layer having a first and second main surface and a covering layer laid against the main surface. The covering layer is made of a multilayer, reflective layer includes a layer of transparent microspheres, which are partially embedded in the substrate, and reflectors, which are located under the layer of transparent microspheres [2].

 Known reflective material containing a base, many rigid reflective elements of a transparent material in the form of retroreflective structures, the bases of which are mounted in the same plane and strengthened by vertices on the base, while the reflective structures are made with a pointed or rounded apex, and part of the side surfaces are located at an angle to a base other than the angle of inclination to the base of the rest of the side surface of the element or elements [3].

 Known flexible laminated retroreflective sheet material, suitable for attachment to a flexible fabric material, used for placement on car bodies in the form of stripes [4].

 Known retroreflective thread used in the manufacture of textile materials [5].

 Known fibrous product with reflective threads that are located on the surface of the product and formed along the length of the material from natural and chemical fibers, can be formed by the structure of knitted, woven, twisted, which can be used in the manufacture of braids, cords, zippers, for tightening the handles , levers, in caps, amulets, for covering road signs, beacons, in life support clothes, cloaks and other garments [6].

 The above materials [2, 3, 4, 5, 6], until they found application in the manufacture of shoes.

 Man is characterized by the so-called color and light coding of shoes and clothes. Color coding with the help of red, orange, yellow, green colors is especially effective in cases when it is necessary to somehow highlight and remember either a person or items of his clothing. At night, the color coding efficiency is reduced, encode objects with light.

Known shoes with lighting devices:
1. Shoes contain a top, a sole and a strip of material on which several light-emitting diodes are located at a distance from each other [7].

 2. Shoes contain front, back and two side sections. An illumination device is mounted to the rear portion of the bracket, containing a current source with which at least one light source and at least one fiber optic fiber with lateral illumination are connected [6].

 3. Shoes containing a flexible upper covering the upper part of the foot, a sole located under the lower surface of the foot and attached to its top, an electric light source mounted in the shoe so that the light is visible from the outside [9].

 4. Shoes, in front of which a lighting system is provided, containing a directional incandescent lamp mounted inside a bent section of the tongue of the shoe, which has an opening for the light beam [10].

 The disadvantage of these shoes [7, 8, 9, 10] is its inconvenience in operation, because To provide a light source with energy, a battery is mounted in the shoes, recharging, changing LEDs, etc. are required.

 The closest analogue is shoes [11], consisting of a sole, sides attached to the sole, the sides (sides) of which are the upper and inner layers, and where the upper layer and the inner layer partially overlap, the reflective surface is made of reflective material and is located between the upper and inner layers so that the reflective layer is partially visible from under the outer layer, the reflective layer is wrapped around the wire, and the wire is along the edge of the shoe.

 The disadvantage of this analogue is in a rather complex technology and rather highly specialized application of reflective material, i.e. only between layers.

 The aim of the invention is to increase the coding of shoes with light, for example, at night, when crossing the road, in emergency situations, etc.

 Another objective of the invention is to increase the aesthetic perception of the elements of shoes and expanding the range of materials used.

 These goals are achieved by the fact that in shoes, including the top blank and the bottom unit, bonded together using chemical, mechanical or combined methods, while fastening by mechanical or combined methods contains external seams, the top blank consists of more than one element, each of the elements is made on the external and internal parts fastened together by seams, some of these seams are made external, while the external parts are made whole, or some of these parts The stitches are made with outer seams connected with the joined parts, the outer seams on the outer parts of the top workpiece elements and / or the outer seams of the bottom assembly to the top assembly are made using retroreflective thread or some of the outer parts of the top workpiece elements are decorated with decorative embroidery using reflective thread, or the outer parts of the elements of the workpiece top are made with applique, fixed with a retroreflective thread.

 According to another embodiment of the invention, shoes, as in the first embodiment of the invention, include a top blank and a bottom assembly bonded together using chemical, mechanical or combined methods, fastening with mechanical or combined methods contains external seams, and the top blank consists of more than one element , each of the elements is made of external and internal parts, fastened together by seams, some of which are made external. The outer parts are made of one-piece or some of these parts are made with external joints, which are connected with the joint of the joined parts. In contrast to the first embodiment, the outer parts of the elements of the workpiece top or bottom assembly according to the second embodiment of the invention are made by applying a retroreflective layer to their outer surfaces.

 In FIG. 1 shows a boot with external seams using a retroreflective thread; in FIG. 2 - a seam laid with retroreflective thread in pre-perforated holes; in FIG. 3 - seam using a retroreflective thread with its fastening along the upper thread of the filament seam; in FIG. 4 - seam using a retroreflective thread, which is attached to the workpiece material, leading the sewing thread from the lower surface of the material to the upper; in FIG. 5 - seam zig-zag using a retroreflective thread; in FIG. 6 - sandal shoes made using retroreflective material, embroidery made with retroreflective thread, zig-zag seam with retroreflective thread depicted in FIG. 5; in FIG. 7 is a general view of the retroreflective material shown in FIG. 6; in FIG. 8, 9, 10 - examples of embroidery with retroreflective thread; in FIG. 11 - seam using a retroreflective thread, which is attached to the workpiece material, holding the sewing thread from the upper surface of the material to the lower; in FIG. 12 is a general view of sandals using braid of retroreflective thread, attached, for example, by gluing or with a thread seam; in FIG. 13 is an example of the decoration of shoes with braid by sewing with a thread seam; in FIG. 14 is a general view of a boot with an application of retroreflective fabric; in FIG. 15 is an example of an outer part of a workpiece upper with a retroreflective layer applied; in FIG. 16 is a section along FJ of the outer part of the preform in FIG. fifteen; in FIG. 17 is a cross-sectional view along the western side of the outer part of the blank in FIG. fifteen; in FIG. 18 is a cross-sectional view of the outer part of the blank of FIG. fifteen; in FIG. 19 shows an example of applying a retroreflective layer in the form of decoration on the material of the outer part of the top of the workpiece.

 The shoes shown in FIG. 1-14, contains a blank of top 1 from more than one part 2, 3, bottom assembly 4, retroreflective thread 5, retroreflective material 6 (Fig. 6, 7), applique 7 (Fig. 14), braid 8 (Fig. 11 , 12). Depicted conditionally in FIG. 15, the outer part 2 of the top of the workpiece with retroreflective material 6 has a different transverse structure depending on the method of applying the retroreflective layer on the material of the workpiece (Fig. 16, 17, 18). In cross section (Fig. 16, 17, 18) are shown: the workpiece material 9, the combining layer 10, the retroreflective layer 11, the polymer film 12 (Fig. 17, 18). In FIG. 2, 4 shows the inner detail of the top of the shoe blank 13, filament seams 14, retroreflective threads 5, braid 8, fastened with filament seams 14.

 Shoes are made using seams with retroreflective thread 5 by the following methods.

 1) In the manufacture of shoes, with the formation of seams with a retroreflective thread 5, the seams from thread 5 are made on the outer parts, for example 2, 3, etc., of the top blank, pre-perforating the blank material 9 (piercing), and then making a needle with a big eye a seam (Fig. 2). After that, connect the outer parts 2, 3 and the details of the lining 13.

 2) In the manufacture of shoes using retroreflective thread 5 in the seams (Fig. 3), the external parts are stitched with a filament seam and the lining 13 is sewn. Then, the retroreflective thread 5 is attached along the seam according to a method similar to [12], with the lower thread in the product, passing along the underside of the fabric base, interwoven with the upper thread passing along the upper side of the base. The retroreflective thread 5, laid along the thread seam 14, is attached to the main thread seam 14. It turns out like an embroidered seam.

 3) In the manufacture of seams using a retroreflective thread 5, this thread 5 is applied to the front surface of the outer part of the shoe blank, and thread 5 is secured with a thread seam 14, introducing the thread from the back of the part (Fig. 4) or introducing the thread from the outside of the part (Fig. . eleven).

 4) External parts are sewn together with a zagzag thread seam, previously stretching the retroreflective thread 5 under the threads (Fig. 5).

 Shoes are made using decorative embroidery made with retroreflective thread 5.

 1) Performing on the contours of embroidery radii, diameters, etc. possible when using yarn 5 of flexible material similar to that described in [4]. The seam is laid using a device similar to that described in [13], which is a hollow needle with the exit of the thread near the lower tip. A seam similar to the vestibule seam shown in FIG. 8, 9, 10, i.e. use the piercing method with the simultaneous introduction of the top or bottom of the retroreflective thread 5 into the workpiece material.

 2) A seam for embroidery on shoes is laid by stitching a retroreflective thread 5 over the surface of the outer part by a method similar to that described in [14]. To do this, draw a contour on the product, along which a retroreflective thread is then applied and attached with a thread seam, turning the needle on top (Fig. 11).

 3) When embroidering, a seam is laid, applying a retroreflective thread 5 along the front surface of the outer part of the shoe blank element, and the sewing thread is brought to the back side and thus thread 5 is fixed (Fig. 4).

 4) A seam for embroidery on shoes is performed by a method similar to that described in [12]. In the product, the lower thread passing along the lower side of the fabric base is interwoven with the upper thread passing along the upper side of the base. The retroreflective thread 5, laid along the thread seam, is attached to the main thread seam (Fig. 3).

 In embroidery with a retroreflective thread 5 or using it, drawn along a drawn or sewn thread seam contour, the stitches are either contoured or completely fill the pattern, as described in [15].

 Shoes are made using retroreflective material by the following methods.

 1) By the method of forming a retroreflective layer 10 directly on the outer surfaces 9 of the outer parts of the top or bottom of the shoe blank. The retroreflective layer 10 on the outer parts of the workpiece upper shoe or bottom shoe assembly is made as follows. On the basis of the workpiece: genuine leather, artificial leather, etc. for example, polyurethane adhesive is applied, combined adhesives are applied to the blanks of artificial leather and PVC. Then, particles are applied by spraying with a reflecting surface of aluminum, bronze, copper, brass, silver powder. Then, for example, a retroreflective layer is applied by scattering through a sieve, for example, microspheres with a transparency of 80-90% with a refractive index of 1.45-2, made of quartz glass, frosted glass, polystyrene, etc. with a size of 30 to 200 microns, covered with a film and passed either between the rollers or under a press. Then it is dried, the film is removed and a finished retroreflective coating is obtained (Fig. 16). Thus, not only a continuous coating is made on shoe blanks, but also inscriptions, ornaments, etc. (Fig. 19).

2) By applying a polymer-based reflective material on the surface of the outer parts of the workpieces of the top or bottom of the shoe using glue or high-frequency welding, as well as by sewing. When using the gluing method, a press similar to that described in [16] is used. The preparation of the top or bottom, for example, of genuine, artificial leather, is coated with polyurethane adhesive, and a polymer-based retroreflective material is applied. Then this preform is placed, for example, on a press between the punch and the matrix, heated from 80 ^o C to 105 ^o C, pressed, then removed, dried. A polymer-based retroreflective material is described in [4]. The resulting retroreflective material 6 in cross section looks as shown in FIG. 17, 18.

 In FIG. 18, the retroreflective layer is made, for example, with microspheres on the front surface; on Fig retroreflective layer, which was previously applied to the polymer base, retroreflective elements adjacent to the surface of the workpiece.

 3) When using a retroreflective flexible material on a fabric basis for preparing the upper of the shoe or, for example, for tightening the heel, the retroreflective material is cut together with the material of the outer part of the workpiece, then a retroreflective material is attached, for example, with a manual thread seam (Fig. 15), then the parts are connected workpieces with seams, sew the lining and attach the bottom assembly using one of the chemical, mechanical or combined fastening methods.

 4) When using a retroreflective material on a fabric basis, such as that from which the outer parts of the workpiece top or bottom assembly are made, the retroreflective material is cut, sewn, or glued or welded by high-frequency welding, connected to the lining and the bottom assembly is attached.

 Shoes are made with applications, for example, FIG. 14. An application of retroreflective material similar to that described in [17] is cut out, then connected to the outer part of the workpiece top or bottom of the shoe, for example, with a filament seam or glued.

 Shoes are made with braid (Fig. 12, 13). When using a braid 8 from reflective material, the braid is sewn in, making thread seams between the retroreflective elements, or a manual thread seam is made, as described above, or glued. The application, braid depicted in FIG. 14, 12, 13 are shown in the conditional image. The retroreflective material of FIG. 7, the embroidery design of FIG. 8, 9, 10 are also shown conditionally.

 Shoes made using retroreflective threads and materials have enhanced decorative properties and increased safety, especially in the dark.
