Description

The utility model relates to the prosthetic and orthopedic industry, namely to the manufacture of orthopedic shoes, such as shoes, boots, etc., for children with static foot deformities: valgus or varus.

Known orthopedic summer shoes for children with pathological feet [RF patent for utility model No. 144382, publ. 08/20/2014], having a top, a sole, soft and hard orthopedic parts, an orthopedic insole, while the top has one-piece ankle boots with perforations; curly backs with lacing, freely covering the top of the shoe along the back-side surface, forming a soft corset that provides stable fixation of the foot inside the boot; supra-ankle strap, located in the upper part of the berets, for a snug fit of shoes in the ankle joint; a special hard back, located between the lining and the top of the berets, having wings extended to the heads of the metatarsal bones on the inside and outside, holding the talonavicular and calcaneocuboid joints during lateral deviations of the foot; orthopedic insoles, the design of which is determined by the type of pathological installation of the child's feet.

The known technical solution has a drawback, since the design of the boots does not allow, at the time of issue, to carry out an individual adjustment (for medical reasons) of mass-produced shoes.

The technical result of the claimed utility model is the ability to carry out individual adjustment of mass-produced shoes at the time of issuance due to the design of the sole, which allows changing the footprint of the shoe depending on the type of deformation. At the same time, ensuring a stable position of the foot when walking is achieved.

The specified technical result is achieved due to the fact that in orthopedic shoes having a top and a sole, according to the present utility model, the sole in cross section is made of a trapezoidal shape, and the width of the running surface exceeds the width of the upper base, from the outer and inner sides of the running surface, respectively, the projection on Channels are made along the line of the protracted edge, inside which stiffening ribs are formed with the possibility of their addition when the channel walls are glued, while the walls of only one of the channels are glued depending on the type of foot deformation.

Thus, due to the combination of essential features of the claimed utility model, it was possible to achieve an individual (for medical reasons) fit of mass-produced shoes and at the same time stabilize the position of the foot when walking. Such footwear allows, at the time of its issuance, to modify the structural components of mass-produced samples, taking into account the identified violations of the static-dynamic function of the foot, and to ensure its stable position when walking due to the inclusion of a trapezoid profile sole with channels in the design of the footwear, which allows changing the footprint of the finished footwear from a given side.

The essence of the utility model is illustrated by drawings, where:

Figures 8 and 9 show photographs of the finished product using shoes as an example.

The claimed technical solution can be implemented in children's orthopedic shoes of any kind, for example, boots, shoes, shoes. The following is a practical implementation of the utility model in shoes for children.

Orthopedic shoes - children's shoes (Figure 1) include a top consisting of one-piece berets 1, a shortened vamp 2, a curly back 3, two lifting belts 4, which is connected to the sole 5 along the line of the long edge.

The sole 5 is made integrally molded and has a trapezoidal shape in cross section, and the width of the running surface exceeds the width of the upper base (Fig.2, 3).

When this running surface of the sole 5 protrudes from the projection line of the protracted edge from the outer and inner side of not less than 5% of the length of the foot (Figure 3). The specified size of the removal of the running surface of the sole 5 relative to the line of the protracted edge is sufficient for children with violations of the static-dynamic function of the foot. As previously conducted biomechanical studies have shown, this value is sufficient to keep the foot in a stable corrected position.

In the sole 5, on the outer and inner sides of the running surface, respectively, the lines of the long edge, channels 6 (Fig.2, 4, 6) are made, inside which stiffening ribs 7 are formed, made with the possibility of addition when gluing the walls of the channel 6. The addition of the stiffening ribs 7 is provided for due to the flexibility of the material of the integrally molded sole 5; for example, each rib 7 is a z-shaped plate attached inside to the walls of the channel 6, along which the addition occurs when the walls of the channel 6 are glued together. The ribs 7 are made of the same material as the entire integrally molded sole 5, since they are its components . Ribs 7 are located at a predetermined distance and at a predetermined angle (preferably 30 degrees to the lingering line of the edge) relative to each other and the walls of the channel 6, so that when folded they do not overlap each other, but are successively folded.

The depth of each channel 6 is 3/4 of the thickness of the sole 5. In the case of a greater depth, the sole 5 may break and the glue will get on the long edge of the shoe. If the depth of the channel is insufficient, then during the operation of the shoe, the glued surfaces of the channel 6 may disperse.

Depending on the type of foot deformation, the walls of only one of the channels 6 are glued: along the outer or inner side of the shoe. For gluing, glue, for example, quick-drying, can be used. Stabilization of the position of the foot in the shoe is achieved by changing the trapezoidal profile of the sole 5, the variability of its area of support and by unilateral (for medical reasons) filling the figured cavities of the channels 6, followed by fixing the sole 5 and the stiffening ribs 7 along the projection of the line of the protracted edge, while the figured cavities channels 6 are closed, changing the mediolateral stability of the foot in the ankle joint.

The claimed footwear is used as follows.

From the standard size range of finished shoes, you should choose a sample, the size of which corresponds to the length of the user's foot; in accordance with the instructions for the use of glue and taking into account medical indications, one-sidedly fill channel 6; hand firmly press the edge of the sole 5 to the folding stiffeners 7 along the projection of the line of the protracted edge until the voids of the channel 6 are completely eliminated.

When issuing shoes, in our case shoes, it is necessary to unfasten the Velcro textile fasteners on the lifting belts 4, insert an orthopedic insole, selected or made individually in accordance with the deformation of the foot; put on shoes and fasten them on the foot, pulling up the lifting straps 4 so that the one-piece ankle boots 1 and vamp 2 tightly cover the heel and metatarsal parts of the foot like a soft corset and do not cause pain; regulate the fixation of shoes on the foot by strengthening or loosening the tension of the lifting straps 4. This also allows you to fix the foot in a functionally advantageous position with a soft corset and give it additional stability due to the one-sided removal of the sole 5.

Examples

1. Orthopedic shoes for children with static deformities of the feet - the shoes were given to a child S. 5 years old, foot length 170 mm, with a diagnosis of flat-valgus feet. Taking into account the medical purpose, individual orthopedic insoles were made with the laying out of the longitudinal arches and the arch support of the calcaneal region. Stabilization when walking in shoes was achieved by eliminating the channel 6 on the outer side of the shoe. The value of the protrusion of the running surface is 8.5 mm. 5% of foot length 170=8.5 mm.

2. Orthopedic shoes for children with static deformities of the feet - shoes with false ankle boots, laced, issued to child A. 10 years old, foot length 235 mm, with a diagnosis of "unfixed varus feet." Taking into account the medical purpose, individual orthopedic insoles were made with the laying out of the longitudinal arches and the pronator along the entire footprint. Stabilization when walking in shoes was achieved by eliminating channel 6 on the inside of the shoe. The value of the protrusion of the running surface is 11.75 mm.
