Description

[Detailed description of the invention] shoe insoles Technical field The present invention relates to a shoe insole that is used by being attached to the inside of the shoe when the shoe is worn. Ru.

Purpose of invention The purpose of the present invention is to improve the comfort of use by improving air circulation. while standing, walking, or running. , an improvement that protects the feet from impact, provides ventilation, and provides comfort and flexibility. Our purpose is to provide insoles for worn shoes.

The present invention utilizes the vacuum effect of coarse porous materials in a double-valve air pressure release mechanism. , which provides an air cushion-like effect when walking. Furthermore, according to the present invention, Absorbs shock while driving and walking, and can be used for long periods of time while standing still. Even if it stands for a long time, it shows resilience against the deformation caused by oppression.

Conceptually speaking, the purpose of the present invention is that when wearing shoes, it is used by being attached to the inside of shoes. , to provide an improved bedding that releases air. When a load is applied, the air The whole process is caused by the intake of air upon release and removal of the load. Easy to perform and provides maximum comfort.

The object of the invention is to provide an outer jacket made of non-breathable material when it comes to air. A hole is provided through the outer cover portion and an air port. It is an object of the present invention to provide a shoe insole having a pumping and air circulation function, By forming the heel part during walking, the first stage when the heel part lands on the ground; A two-stage air pumping action occurs, with the second stage occurring when the front part of the foot lands on the ground. By crawling, air circulates between the foot and the insole inside the shoe. Provide a litter that is drained and released and circulated either permanently or continuously. There are many things.

This air flow cools the feet, provides comfort, and ventilates the feet. Further, a pad of foamable material is included within the jacket portion to provide impact protection. absorb the blow. It acts as a good buffer for the tank.

In accordance with the objects set out above and other objects which will become apparent hereinafter, the present invention has been made. will be described in detail with reference to the accompanying drawings.

Brief description of the drawing FIG. 1 is a bottom view of a bedding according to the present invention.

FIG. 2 is a top view of the bedding according to the present invention.

FIG. 3 is a cross-sectional view generally taken along the center line 3--3 of the bedding.

FIG. 4 is an enlarged cross-sectional view of the bedding at line 4--4.

FIG. 5 shows a slightly modified embodiment of the embodiment shown in FIG. 4, which is almost the same as that shown in FIG. FIG. 3 is an enlarged partial cross-sectional view in position;

Detailed Description of the Preferred Embodiment Items with the same reference number in each drawing refer to the same reference number in each drawing. indicates the same or corresponding parts.

In Figure 1, the bedding is a flexible plastic board that is resistant to air. The outer cover portion Oa is made of an impermeable material. The outer covering portion is a flat surface. It has an external shape that is modeled after the outline of a human foot, and has an upper surface side and a lower surface side. 6) and a side surface 0.

In order to facilitate the explanation of this embodiment, the outer shape of the outer cover portion is shown as the heel portion (2 0), a front portion t221, and a middle portion (24).

A hole C0 having a diameter of approximately 6.35 mm (one quarter inch) passing through the middle portion is located on the side. The hole is drilled separately from the edge, and the hole is located approximately in the longitudinal direction of the bedding. Preferably, it is provided on the core wire. A pad made of cushioning material (the second one is disposed within the jacket portion. This pad (28+ is the upper surface part and the lower surface part) It is sandwiched between the outer covering part and has a size that substantially fills the inside of the outer covering part. Ru.

The side surface portion α8) is formed by bending the peripheral portion of the upper surface of the outer cover portion at right angles downward. The part that curves outward and downward (30 ). Further, in the side surface portion, a peripheral portion of the lower surface portion of the outer covering portion is directed upwardly. It consists of a part that is curved by external force, and the tip of the part is shown in the drawing. As shown by the symbol □□□), the lid-shaped forming an edge (34).

The padding within the jacket portion is made of a flexible foam material, and A plurality of through holes (40) and (421) are formed over the entire surface of the pad except for the It is convenient if they are arranged and drilled in a fixed pattern.

In this embodiment, there is a wall thickness of approximately 1.5 mm between the pad and the upper surface portion. , 6 m ( Thin membrane of elastic material from 1.6 m (1/6 inch) to 3.2 m (1/8 inch) a layer (46) is provided on an inner surface of the upper surface portion of the pad and the outer covering portion; There are nine glued on.

Preferably, the pad contains very high quality charcoal throughout. Before The upper surface of the outer covering part is made of flocked material as shown by the symbol (4) in the drawing. However, it is preferable to have a smooth cloth-like texture and friction properties. Said The upper surface portion and the lower surface portion are heat-sealed together. The lower surface portion is It can be made of polyethylene plastic plate material.

When using the above-mentioned insoles inside shoes, if the user lands on the heel first, When walking, air flows through the pad made of foam material and into the jacket portion. inside the front part. At this time, some of the air is released through the hole.

When you step out your legs one after another and walk, pressure is also applied to the front part of the outer covering, so the air A portion of the air is released again from the intermediate part, so that the user of the bedding In addition, the air inside the shoe is better circulated, providing greater comfort. , gives more flexibility and reduces fatigue.

The outer cover portion may be made of flocked or transparent vinyl plastic material. You can also do it. The upper surface portion is approximately gauge 8, and the lower surface portion is approximately gauge 1o. It is preferable to set it as the number.

The overall height of the lining is suitable for 48 m (3/15 inch), and 127 doors (2 min. 1 inch) and 16 taki (1/16 inch). downward The curved periphery is a protective part and prevents the user from feeling pain in the foot. , prevents shoes from blistering.

In the embodiment shown in FIGS. 1-4, hole C0 passes through the entire device. However, in contrast to the holes, in the embodiment shown in FIG. 41 and the lower surface portion 0θ, the upper and lower ends are sealed, respectively.

In the case of this embodiment, almost no air is discharged from inside the bedding, but Although they have almost the same effect and do not have a pumping effect to circulate air, The effects of the present invention can be fully exhibited.

The present invention, as described above, has been described in detail using the embodiments considered to be the most practical and preferred. However, within the technical scope of the present invention, the implementation disclosed herein It is possible to make various modifications without being limited to the examples, and It is possible to cover all devices modified and implemented in this manner.
