Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the insole structure of footwear, and in particular, the insole member having a flange is fitted into the insole part which is made hollow leaving the peripheral area. This relates to the insole structure of footwear worn by the wearer.

[Prior Art] In conventional footwear, the sole and the midsole, which comes into direct contact with the foot when the shoe is worn, are generally formed integrally, and the midsole has a flat surface on both the front and back. Even in footwear in which the sole and the midsole are molded separately, the two are fixed together with an adhesive, and the midsole is molded from a foamed plastic material with varying thickness. Usually, the degree of cushioning is varied.

[Problem that the invention attempts to solve]

Therefore, in conventional footwear, especially those in which the sole and the midsole are molded separately, it is necessary to perform a step of fixing the sole and the midsole together with adhesive or the like. . In this process, the adhesive is first applied as evenly as possible to the upper surface of the sole, the insole with fabric etc. attached to the upper surface is inserted into the shoe, and then heated and crimped using a crimping means having a shoe last. It is necessary to.

However, although the above steps seem simple, they are actually quite complicated, and this is a major obstacle in reducing the manufacturing cost of footwear.

In addition, with conventional footwear, it is not possible to change to an insole with different elasticity and flexibility depending on the road surface condition such as unevenness, the type of exercise such as marathon running, jogging, hiking, etc., or the strength of the exercise movement. Conventionally, it has been necessary to replace the footwear itself or to separately purchase and use a suitable insole, which is extremely wasteful.

The present invention was developed against the background of the above-mentioned circumstances, and involves fitting an insole member having a flange into a hollow insole part leaving a peripheral area in the insole structure of footwear. It is an object of the present invention to provide an insole structure that simplifies the manufacturing process and can be replaced with an insole member having a different degree of flexibility and degree of stimulation to the sole depending on the application.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has an insole structure for footwear that is hollow except for the outer periphery of the insole. An insole member comprising: an insole front, a bottom surface with a plurality of spherical protrusions protruding over the entire surface, and a flange extending from the outer peripheral edge of the insole. The gist is that the outer peripheral edge of the middle bottom portion is brought into contact with the cover by the flange.

Further, the midsole member has, on the midsole surface thereof,
It is characterized by a plurality of small spherical protrusions arranged in series.

Further, the midsole member has, on the midsole surface thereof,
It is characterized by a small protrusion protruding upward so as to correspond to a protrusion provided on the back of the midsole.

[Effect]

The present invention allows the insole member to be removably fitted and seated in the hollow insole by the above-mentioned means, and the spherical protrusion protruding from the back of the insole allows the shoe to be Shocks from the ground transmitted through the sole are buffered, and small protrusions provided on the midsole member provide regularly changing stimulation to the sole of the foot.

Furthermore, since the outer circumferential edge material of the midsole is brought into contact with the cover by the flange extending from the outer peripheral end of the midsole, the midsole does not come off or protrude from the midsole.

〔Example〕

Next, preferred embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 shows an embodiment of the present invention implemented in sports shoes.
The midsole portion 30, which is covered by the shoe sole 20 and is placed and fixed on the sole 20, is hollow inside except for the midsole peripheral material 32. This hollow inner bottom part 30
The inner sole member 34 is fitted and seated inside.
This midsole member 34 has a substantially flat midsole surface 340 on its upper surface, and a plurality of spherical protrusions 344 protruding downward from its lower surface as a midsole back surface. A flange 346 is provided around the outer peripheral end of the flange 346 so as to extend in the horizontal direction.

The midsole member 34 is usually molded from a foamed plastic material having elasticity.
Normally, cloth or the like is pasted on the entire surface of 40, but this is not shown because it is a known technique.

In this embodiment, a plurality of hemispherical spherical protrusions 344 are provided on the entire surface of the inner sole back 342, projecting downward; however, as a result of the trial test of this embodiment,
This is because it has been found that the spherical protrusion has excellent shock absorption results during intense exercise, and provides sufficient shock absorption even when the sole of the foot is twisted against the insole member 32. It is.

However, when performing relatively light exercise such as jogging or walking, the inner sole 342 may have a single protrusion as a whole, or a plurality of continuous or discontinuous aspherical protrusions ( (none of which are shown) is also possible. Therefore, in the present invention, the protrusions provided on the inner sole 342 are not limited to the spherical protrusions 344.

In addition, a flange 346 is provided around the outer peripheral edge of the insole member 34 along the insole surface 340, and this flange 346 allows the inner wall surface of the toe skin 10 to come into contact with the inner wall surface of the toe skin 10, and at the same time, the inner wall surface of the insole part 30 By covering and abutting the midsole peripheral material 32, the midsole member 34 fitted into the midsole portion 30 can be reliably seated without shifting or protruding.

FIG. 2 shows another embodiment of the present invention, in which the midsole 30 is similar to the first embodiment.
The inner sole member 34 having a flange 346 surrounding the inner sole member 34 is fitted into the hollow portion of the inner sole portion 30 and is seated therein. Insole surface 34 which is the upper surface of the insole member 34
0, a plurality of small spherical protrusions 348 are provided to protrude upward so as to correspond to the plurality of spherical protrusions 344 protruding from the inner sole back 342.

The purpose of arranging the plurality of spherical small protrusions 348 on the midsole surface 340 is to provide regular pressure stimulation to the sole of the foot with these spherical small protrusions 348.
This is to achieve a pine surge effect, and is suitable for casual shoes, walking shoes, etc.

However, depending on the case, the number of small protrusions on the inner sole surface 340 may be greater or smaller than the number of protrusions on the inner sole back 342, or may have a shape other than a spherical protrusion. It is also possible to do this.

[Effect of idea]

As described above, the present invention adopts a removable, mating seat-type insole structure for the insole structure of footwear. Not only can one piece of footwear be used for many different purposes, but especially in sports shoes, if the spherical protrusion is used as in this example, a sufficient impact absorption effect can be achieved, and the process of attaching the insole can be improved. Since this can be omitted, manufacturing costs can be reduced.

In addition, by arranging small protrusions on the midsole surface,
The pine surge effect on the soles of the feet can also be increased.

Furthermore, since the insole member can be removed and washed, there is no need to use an insole, which is extremely convenient and economical.
