Description

[Detailed description of the invention] stability shoe device Background of the invention The present invention relates to shoes, particularly for hyperpronated, hypersupinated runners or heel strikers. l　5trikers) and substantially main mechanical (BIOS+Echanic) al) Runners without problems, i.e. runners with a neutral gait, but with additional shock dispersion and regarding shoes for those who desire flexibility. To achieve the above task, memory A cushion containing unpressurized air and cells of a specific shape with ) preferably at the midsole of the sliplasted shoe. Preferably, it is hung within the handle.

Generally speaking, shoe patents in this technical field include U.S. Patent No. 4,223, No. 455, No. 4,878,300 and No. 4.854,057.

Summary of the invention The present invention aims to provide a cushioned shoe for users, especially runners. In the case of specific runners with major mechanical problems, correction, rehabilitation, and how the cushioned pad of the invention is used in the shoe. Provides stability.

The cushion of the present invention is made of plastic material and has individual cells and memory. The cell walls are constructed of walls so that the cell walls substantially return to their original shape after compression.

Each of the above cells contains unpressurized air at ambient temperature, so that the cell is temporarily punctured. It remains as it is even at times. not damaged. Preferably used on the back of the shoe The cell is higher than the outer periphery for stability and has an anatomical heel clay. It combines with lower-height inner cells to form a dollar. 1! ! Mr. The cushion (pad) is disclosed in U.S. Patent No. 4,878,300. It is integrated with the type of impact dispersion plate described in the above for a stronger effect and cushion. Provides more stability while maintaining flexibility.

Detailed description of the invention Referring to FIGS. 1 and 2, at 40 a representative shoe of the present invention is shown. This shoe is Slip-last type shoes, e.g., U.S. Pat. No. 4,854.05 Sliplast shoe upper made of leather, fiber, or other compositions as described in No. 7 41.

42, for example, intermediate materials made of foam materials such as closed cell foams such as EVA. The sole is shown and 43 indicates the rubber outsole.

In Figure 2 the underside of the shoe is shown. This is due to this at 43-1. It has an opening formed in the cushion 45 and can be installed in the case 46. Show that.

Figure 3 shows that the intermediate sole is composed of two sections, 45 and 48. . The intermediate sole portion 48 forms a rear opening 48-1, in which the rear heel opening 48-1 is formed. The knit 45 is installed like a jigsaw puzzle. The top surface of this unit 45 and the underside are shown in Figures 4 and 5, respectively. In FIG. 4, unit 4 5 has an upper opening 45-1. This upper opening 45-1 is the cushion unit 4 It is formed in the molding process used to form 5. Cushion unit 45 The foam shell encapsulating the exterior of is shown in cross section in FIG. Figure 5 shows the uni The bottom of the pad 45 and the opening 45-3 are shown, and the cushion portion 50, i.e. the center A cell 50-1 is shown.

The cushion 50 is made from a sheet material by a vacuum method or by an injection molding method. is particularly useful for runners who are heel strikers. Cushion 50 is sexy consists of a section 50-A and a bottom section 50-B, which are symmetrical to each other. or may be different as desired. Each section 50-A, 50-B is outside. The cells 50-2 to 50-4 are composed of central circular cells 50-1 and 50-4. It is taller than -5 and can form an anatomical heel cradle.

Each of the above cells contains unpressurized air at ambient temperature without being interconnected as shown. The sufficient thickness of the cell wall is about 0.7 to 1.5 cm, preferably l +u+. The cell wall retains memory, i.e. substantially its original shape after compression. Return to Sections 50-A and 50-B of the cells are each made of, for example, an adhesive or or sealed together to form individual cells by other methods known in the art.

8, U.S. Pat. No. 4,854, herein incorporated by reference. A buffer plate 54 of the type described in No. 057 and No. 4.878,300 is It is shown.

The plate illustrated in FIG. 9 has cushion sections 50-A and 50- B, for example, by bonding with adhesive to form the upper and lower cells separately. to be accomplished.

The cushion unit in Figure 9 provides additional shock dispersion flexibility to the cushion unit in Figure 6. Grant. This cushion unit is installed in a shoe with the same structure as shown in Figure 6. Ru. For example, woven or cut fiber glass containing 25% polyester resin. It is made of a composite material. This force distribution plate is preferably flexible. It is essentially non-stretchable.

Figures 10A and ], OB further show the cushion form, and a plastic plate made of the same material as the cell. A sheet of plastic or other plastic is bonded to the cell. The above cookie As mentioned above, the cell is placed inside the shoe, for example, as shown above, in the middle of the shoe. It may be used by encapsulating it in a container.

Referring to the intermediate sole 60 of FIGS. 11-16, this intermediate sole is designed to prevent supination. It has a cushion unit 70.

The intermediate sole 60 is formed of a first section 71 and has a rear opening 71-1.

A cushion unit 70 is installed in the opening 71-1, and this cushion unit at the arch of the shoe on the outside of the midsole 60 and on the opposite side of the midsole 60. It extends to The forward recess or groove 72 is as illustrated in FIGS. 20 and 21. Provided to receive a cushion 46.

FIG. 16 has two top sections 75-A and a bottom section 75-B, and FIG. 1 to 7;

Furthermore, the front self 5-6 and 75-7 are provided to provide a supination prevention effect. ing. These Kunjong cells are independent of each other and, as mentioned above, are Contains unpressurized air. The cushion unit 70 rotates the cells as shown in FIG. Closed cell foamed plastic (EVA) shell encapsulating the exterior of the , the intermediate sole of which is used in a shoe as described above.

Figure 17-A shows a combined symmetrical cell assembly to provide additional impact dispersion and flexibility. Forces similar to those described above used as illustrated in Figure 17-B between the sections The distribution plate is shown.

18-A and 18-B are sealed with a plastic sheet or plate 80. These morphologies exhibit cushioning properties as desired. Can be used to grant.

FIG. 19 shows the cushion unit 80 installed in the opposite direction in the intermediate sole 81. show. This cushion unit has a pronation prevention effect with the unit and cushion. extending to the beginning of the shoe's arch on the inside of the midsole to provide A recess 82 is provided in the front cushion as desired.

Referring to FIGS. 20 and 21, the forefoot cushion is indicated at 45.

The cushion is not encapsulated, but in a recess 90 within the midsole 90 of the shoe. -1 as described above. The individual cells are indicated at 91 and are preferably located at a lower position within the recess of the cell and sealing the same material as the cell or the individual cell 91. Covered with a plastic sheet 94 made of other plastic material for It will be done. The cell contains unpressurized air at ambient temperature.

FIG. 22 shows two blocks installed in a sealed manner together in a recess 97-1 in an intermediate sole 97. Another pre-kungjon configuration is shown having cell sections 96A and 96B.

Figure 23 shows a state-of-the-art cell unit, where cell 9 is a plastic sheet 9 9 closes the bottom and allows upward movement.

The cushioning cell member described herein may optionally be used in a sock in the inside of the upper of a shoe. It can be installed inside the liner.

FIG, +9 FIG. 20 FIG. 21 abstract An athletic shoe is disclosed that includes an intermediate sole (42, 60, 81, 90, 97); The intermediate sole has independent and separate cells in a cushion unit (45, 5 0,70,75,80), and the cell contains unpressurized air. The above cell is It not only works to stabilize the foot, but also has extra cushioning to protect the runner. do.
