FIELD OF THE INVENTION The invention relates to the shoe industry, in particular to the construction of a shoe bottom assembly.

The purpose of the invention is to provide ease of operation.

The materials used for the bottom of the shoe, i.e. hard shoe materials have significant resistance to bending, to overcome which energy is inefficiently consumed. When walking, also when lifting and bending the foot, the rhythmic lag of the exact and delicate part of the shoe from the footprint of the foot occurs.

The spring action ensures a constant snug fit of the bottom to the footprint at rest and when walking. This will eliminate the rhythmic lag, the exact part of the footprint when walking, appearing after a short sock of ordinary types of shoes.

FIG. 1 shows a low-heel bottom shoe assembly, horizontal projection; in fig. 2 shows section A-A in FIG. one; Fig. 3 shows the bottom of the shoe assembly, a vertical projection with a minimum spring tension (with a regiment of bending of the foot in flat phalangeal joints or in shoes not fitted to the foot); in fig. 4 - bottom platform assembly with a high platform, horizontal projection; Fig. 5 is a section B-B in Fig. 4 (the position of the bottom of the shoe at the maximum spring tension is shown, which occurs when the entire foot is supported on the surface of movement); in fig. 6 - bottom shoe assembly, vertical projection with minimum spring tension (with full flexion of the foot in plus-fapang joints or in shoes not fitting to the foot).

The knot of a bottom of shoes contains a sole 1 with a heel 2 located in her insole 3 placed between

53591, 2

With these parts, prodil 4 with a heel is 5 and a plate spring bent in a free state 6 with horizontal and inclined sections, installed between the crook and the sole in the section from the beams to the middle of the heel, with the horizontal section of the spring located in the beam part of , and the slope is 0 in fine. Placed at the bottom of the shoe assembly, the plate spring 6 is a strip with an extension at the support end. In the free position (without voltage) the spring

15 6 is bent and forms an obtuse angle (angle f). The vertex of the angle lies approximately between the beam and the gelenc. The supporting part of the plate plate, pressing the bottom of the shoe to

20 a trace (the sole of the foot passes under the gelenk into the right part) forms an angle oi varying with the surface of movement (floor, road, etc.).

25 Plate spring 6, with horizontal and inclined sections in the bottom of the shoe with platform 7, is placed between the sole 1, the platform 7 and the stretcher 4 with the heating rod 5,

30 overlapped on top of the insole 3.

The constant and tight fit of the bottom of the shoe to the foot (sole) of the foot, which does not weaken over time, hinders progress, and its rhythmic lag of the right and inferior parts from the foot (foot) of the foot when walking is worn. Constantly firmly pressed to the track (sole)

40 of foot, the exact part is less subject to wobbling and distortions, which is typical for shoes without backs.

The job of this bottom of the shoe is that when you change

The 45 positions of the foot of the foot change the position of the leaf spring. L

Claims (1)

SHOES UNDER SHOES, containing a sole with a heel, located above it insole, a calf-bed with a calf placed between these parts and a leaf spring with horizontal and inclined curved in the free state: sections installed between the cloth and the sole in the section from the bundles to the middle of the heel part, characterized in that, in order to ensure ease of use, the horizontal section of the spring is located in the beam part of the shoe, and the inclined section is in the heel.
