Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an outer sole for shoes.

[0002]

[Prior art]

 FIG. 6 shows an outer sole 10 for a conventional shoe. Generally, the outer sole includes a bottom with a number of patterns. This provides better friction properties and provides an upper surface on which the large number of ribs 11 expand. These ribs 11 are arranged in a number of various patterns to define a number of chambers 12. An insole not shown is connected to the rib 11. The chamber 12 is designed to provide cushioning properties so that a person wearing the sole can have a comfortable feel when walking or running. However, it is difficult to exhibit the desired friction characteristics. Because the ribs 11 are made from a material that is not soft or soft, slight deformation of the ribs 11 reduces the desired cushioning properties. Some lightweight and soft materials are being developed, but they are expensive. In addition, the conventional outer bottom is a solid member, and is therefore heavy. Some new expensive outer soles have multiple air cells on the heel to get better bounce characteristics. These types of outsole are manufactured in many complex processes, and the air cells are located only in certain areas of the outsole, for example, in the heel.

[Problems to be solved by the invention]

 The present invention aims to provide an outer sole having a cushion chamber at a position inside the outer sole. Another object of the present invention is to provide a lightweight shoe outer sole having good frictional properties and cushioning properties for providing a comfortable feel.

[0004]

[Means for Solving the Problems]

 An outer sole for shoes according to claim 1 of the present invention for achieving the above object is an outer sole for shoes including a basic member and a midsole, wherein the basic member includes a basic member main body, A first flange extending from a periphery of the basic member main body, a second flange extending from an upper surface of the basic member main body, and a peripheral groove defined by the first flange and the second flange. The bottom has an insole body, a skirt extending from the periphery of the insole body, fitted in the circumferential groove of the basic member, and supported by the second flange, wherein a cushion chamber is provided in the insole body. And the upper surface of the basic member main body and the second flange.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the outer bottom according to the embodiment of the present invention includes a base member main body 26 of the base member 20, a first flange 21 extending from the periphery of the base member main body 26, and a base member main body 26. And a second flange 22 extending from the upper surface of the second member. Thereby, the peripheral groove 23 is defined by the first flange 21 and the second flange 22. The plurality of separation posts 25 extend from the upper surface 24 of the basic member main body 26. The second flange 22 is longer than the separation post 25.

As shown in FIGS. 2 and 3, the midsole is engaged with the basic member 20 and has a wave member 30 and a cover member 40. The wave material 30 has a wave material body 34 as an insole body and an engagement flange 31 as a skirt extending from the periphery of the wave material body 34. The engagement flange 31 is fitted in the peripheral groove 23 of the basic member 20. When the wave material 30 is engaged with the circumferential groove 23, the gap 50 is defined between each separation post 25 and the wave material 30 when the wave material 30 is supported by the second flange 22. Since the engagement flange 31 is smaller than the width of the peripheral groove 23, the gap 33 is defined between the inside of the first flange 21 and the engagement flange 31. The cover member 40 is attached to the wave member 30 and seals the gap 33 as shown in FIG. That is, the midsole has a skirt composed of the engaging flange 31 and the peripheral portion of the cover member 40. The material of the peripheral portion of the cover member 40 is filled and is sealed by the gap 33.

The cushion chamber 50 is defined by the midsole, the upper surface of the basic member 20, the second flange 22, and the lower surface of the wave material 30. As shown in FIG. 4, the position and area of the outer bottom cushion chamber 50 can be conveniently determined to be included in the entire outer bottom. As shown in FIG. 5, the cushion chamber 50 can be provided only at the heel portion on the outer bottom. When the midsole is stepped down with great force, the separation post 25 provides proper support. The number of the separation posts 25 and the positions of the separation posts 25 are determined as appropriate according to actual needs. The outer sole is light in weight and has an air cushion throughout the outer sole. The above embodiment of the present invention provides an outer sole having cushion chambers at all locations within the outer sole.
