Description

It relates to insoles used in shoes.

Some insoles used in shoes have specific effects and functions such as deodorizing effects, antibacterial effects, and fatigue recovery functions (hereinafter collectively referred to as “specific functions” where appropriate). .
However, from the viewpoint of not impairing the comfort of shoes, these are made using materials processed on the entire insole, materials with special medicinal effects, or materials with special processing. In many cases, it is used for the entire floor, and the continuity of the above-mentioned effects and functions is short-lived.
In addition, even in insoles for the purpose of specific functions such as fatigue recovery function, thinly-made items are attached to specific parts of the insole each time using double-sided adhesive tape etc. For this reason, there are many things that are easily peeled off and lack retainability.

Therefore, when using a product that exhibits a specific function but has increased thickness due to the nature of the product, such as a heating hood, in the shoes, the user feels uncomfortable while walking due to the thickness, shape, etc. This causes problems such as worsening the walking, increasing walking fatigue, and easily forming beans on the feet, so the current situation is that it is simply placed on the lower or upper part of the insole.
In addition, in the case of use as described above, since the above-mentioned item becomes an inclusion between the shoe or the insole and the foot, it may be necessary to procure a slightly larger shoe.
In addition, if you do not walk, such as fishing in winter or watching a game in an outdoor stadium, it can be used, but if you are walking, the inclusions are not fixed to your shoes or insole. In addition to not being able to fully function, problems such as difficulty in walking, increased fatigue, and beans on the legs arise.
For these reasons, no means has been found in the past that can be used positively by putting something having a specific function into a shoe without impairing walking.

It seems that it does not exist. I searched the Gazette Text Library (Public Patent Gazette) in the Patent Electronic Library under the following conditions, but there is nothing that can be considered as applicable. “Summary + Claim” “Shoe Insole Insole” AND “Summary + Claim” “Concave Dimple Dimple Concave” AND “IPC” “A43B17 /?” 83 cases were found

The present invention has been conceived under the circumstances as described above, and a product having a specific function and having a predetermined shape (hereinafter referred to as “predetermined shape filling”) is actively embedded in an insole. Provide an insole that can be used continuously without losing comfort and without causing any obstacles to walking, allowing specific functions of a predetermined shape of the packing to be used by making it freely replaceable. The task is to do.

  Therefore, the present invention provides a predetermined portion of the insole with a concave portion corresponding to the shape of the predetermined shape filling (hereinafter referred to as “concave portion” as appropriate), and further provides a cover for covering the predetermined shape filling. The mechanism allows the filling material to be freely put in and out.

  Furthermore, in the mutual restraint between the periphery of the concave portion and the outer periphery of the cover, a part of the insole around the concave portion and a part of the outer periphery of the cover are fixed, and a part is covered with a fastener with a fastening member. Can be freely opened, closed, and restrained so as to simplify the entry and exit of the predetermined shape filler and prevent the predetermined shape filler from moving.

In addition, an air reservoir is provided at the bottom of the heel portion of the insole, and an air supply groove is provided from the air reservoir to the concave portion so that the specific function of the predetermined shape filler can be further exhibited.

  The invention of the present application is in a state in which a predetermined shape filling is embedded and sandwiched in a concave portion provided in a predetermined portion of the insole, so that a comfortable feeling is not generated even when wearing shoes or walking. There is little damage.

  In addition, since it has a concave shape corresponding to the thickness of the insole, it can be used even with a thick predetermined shape filling.

  Furthermore, since the cover covering the concave portion is provided, the predetermined shape filler is embedded and sandwiched in the concave portion, and hardly walks away from the concave portion during walking, and the predetermined shape filler It is easy to replace at any time.

  In addition, the insole part around the concave part and a part of the cover outer peripheral part are fixed to each other between the periphery of the concave part and the cover outer peripheral part, and the part is covered with a fastener with a fastening member. Because it can be opened and closed and restrained freely, the filled product of the predetermined shape will not be detained and removed during use, and the filled product of the predetermined shape will not move, so it will become familiar with the concave part and feel strange when walking. Disappear.

  In the normal case where the specified shape filler is not used, insert the specified shape of the same material as the core material attached to the insole and use the specified effect / function. Materials with good motor functionality, such as cushioning, when using substances that have a certain shape, such as warming hoods, athlete's foot antiseptics, deodorants, etc. By using what consists of as a predetermined shape thing, it can respond to all-season with one set of insoles for such a versatile thing.

In addition, many fillers with a predetermined shape perform their functions when supplied with air. For this reason, a groove for air supply is provided at the bottom of the insole from the heel part to the concave part so that it is concave from the heel that is landed first during walking. Since the air can be supplied to the part, the function of the predetermined shape packing can be further exhibited.

An example of an insole that implements the present invention is shown in FIG. 1 (Example 1) and FIG. 6 (Example 2).
In the embodiment, an example in which the present invention is applied to the toe portion is shown, but the scope of the present invention is not limited to this, and the present invention can be applied to any portion of the sole such as an arch portion or a heel portion.

1 and 6 are perspective views of the insole as seen from the bottom, and FIG. 2 is a longitudinal sectional view of the insole of the first embodiment.
The insole is made of a material in which the top material 14 is bonded to the core material 10.
As a material for the core material, a foamed and cushioning synthetic resin material is used, and for example, EVA (Ethylene-Vinyl-Acetate Copolymer) is now widely used. .
As the upper surface material, a woven fabric of Kanoko, which is generally referred to as Kanoko, is used.
Note that the insole of the present invention is provided with a folded back (shown by a two-dot chain line in FIG. 2) from the side of the foot to the rear.

In the insole, first, the material to be the core material 10 is cut into a foot shape, and then folded and processed such as the air reservoir 18, the air supply groove 19, and other grooves while being heated by a predetermined mold. The
Next, a predetermined portion of the core material, for example, a toe portion, is removed using a mold so that a concave portion 11 corresponding to the shape of the predetermined shape filler 50 is formed. The removed concave portion equivalent product is subjected to a release / peeling process so that it does not adhere to the upper surface material 14, and is then fitted into the core material, whereby the upper surface material is adhered to the core material.
The fitted concave portion equivalent product is removed, and vent holes 15 having a diameter of about 1.5 mm are opened in a lattice shape at intervals of about 10 mm in the concave portion of the upper surface material (FIG. 4).
Thereafter, a cover 20 made of non-woven fabric or fabric is attached to the opposing surface of the concave portion.
In addition, the concave portion equivalent product which has been removed and subjected to the release / peeling process is used as a predetermined shape attached to the insole.

FIG. 3 is a bird's-eye view of the bottom surface of the insole of the first embodiment, and shows a state before the cover 20 is closed after the filler 50 having a predetermined shape is inserted.
A part of the periphery of the cover is sewn as shown by a sewing machine stitch 31 in a pocket shape with the upper surface member 14 (FIG. 2) through the core member 10 so as to sandwich a predetermined shape filler. In addition, you may adhere | attach with an adhesive instead of sewing, and you may heat and weld.

Further, if necessary, fasteners 16 and 26 with tacking members, commonly referred to as magic tape (registered trademark), are attached to the upper surface member 14 or a part of the periphery of the core member 10 and the cover 20 by sewing or adhesion / welding. (FIG. 1, FIG. 2, FIG. 3).
As a result, the upper surface material or the core material and the cover can be freely opened and closed and restrained, so that the predetermined shape filler 50 can be easily put in and out, and the predetermined shape filler does not move or leave. In addition, in the Example of this invention, although the collar member side of the fastener with a fastening member is attached to the upper surface material or the core material, you may attach the loop material side.

Although FIG. 3 shows a situation where one air reservoir 18 and three air supply grooves 19 are provided at the bottom of the insole, the number of air reservoirs and air supply grooves may be arbitrary. FIG. 4 is an overhead view showing the upper surface of the insole, and the fastener 16 with the tacking member is indicated by a broken line as an imaginary line.
The air stored in the air reservoir is supplied to the filler 50 having a predetermined shape via the air supply groove upon landing during walking, and flows out to the sole through the small hole 15.
In particular, when a warm-heated squirrel or the like is used as a filling of a predetermined shape, air is necessary to exert its effect, so appropriate air supply by the air reservoir / air supply groove is extremely effective. is there.

  FIG. 5 is a perspective view showing a situation in which the predetermined shape filler 50 is put in and out of the insole of the first embodiment. As shown in the figure, it is very easy to put the predetermined shape filler into and out of the concave portion 11 and pinch it. It is.

FIG. 6 is a perspective view showing an insole of the second embodiment.
In the first embodiment, the core material 10 and the cover 20 are fixed together by sewing or the like so as to form a pocket shape. However, in the second embodiment, the core material and the cover 40 can be opened and closed in a door shape from the toe. In order to sew both, etc., and to hold them together, fasteners with tacking members are used on the periphery of both the core material and the cover.
In this case, the predetermined shape filler 50 can be put in and out from the upper surface (upper surface material side) of the insole without turning the insole upside down.
Of course, in order to supply cheaply, the fastener with a fastening member can also be abbreviate | omitted.

In the case of Example 2, when using a thick fastener with a fastening member, the predetermined portion of the core material 10 is cut off without being recessed, and the cover 40 is attached, thereby reducing the thickness of the fastening member with fastening member. It is also possible to use the core material as having a function similar to that of the concave portion without forming the predetermined portion of the core material into a concave shape.

  Since the invention of the present application is a mechanism in which a concave portion and a cover are provided on a conventionally used insole of a shoe, and a predetermined shaped filling can be freely put in and out between them, production as an insole Therefore, the industrial applicability is extremely high because the increase in production cost is negligible.

In addition, since the insole is provided with a concave portion and sandwiched so as to embed a predetermined shape filling corresponding to the shape, the predetermined shape having a specific function and medicinal effect without impairing the comfort of shoes. By using the filler, it is possible to exert effects such as heat, walking fatigue reduction, medicinal use and the like, and it is highly possible to use in the health and medical industries.
Furthermore, since the present invention can be applied not only to the toe portion but also to any portion of the sole such as the arch portion or the heel portion, it can contribute to the fields of health and medical care.

In addition, since the predetermined shape filler can be easily replaced and used, it can be used for various functions, and is useful in many industrial fields related to the filling material of the predetermined shape filler.

It is the perspective view which looked at the insole of Example 1 from the bottom face. 1 is a longitudinal sectional view of an insole of Example 1. FIG. It is the bird's-eye view which looked at the bottom of the insole of Example 1, Comprising: It is a figure which shows the condition before inserting a predetermined-shaped filler and sealing a cover. 3 is an overhead view showing the upper surface of the insole of Example 1.
