Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a shoe sole structure,
The present invention relates to a foot-shaped sole structure insole and a filler used for the sole structure.

[0002]

BACKGROUND OF THE INVENTION Sole construction is understood to mean the entire shoe located below the sole of the foot. Quality, purpose,
Depending on the material, the sole structure may be single layer or multi-layer. The multi-layer sole structure is a structure in which a plurality of partial soles are integrally formed and fixed to each other. A sole structure in which another removable sole, that is, an insole that can be detached from a shoe is arranged on a single layer or a multi-layer partial sole integrally formed is also called a multi-layer sole structure. Although the single layer sole structure extends over the entire sole, the partial sole may be formed so as to cover only a part of the sole, for example, the heel or the part of the foot ball. The term "shoes" does not only mean shoes, but also includes boots, sandals, wooden sandals and similar other footwear.

It has been found that the human foot acts, so to speak, as a temperature sensor. This is also evident, for example, in the fact that the foot quickly sweats at high temperatures. It is known that there is a high-density sweat gland in the human foot, especially the sole of the foot, especially the part of the foot ball. The feet are often stored inside the shoe for extended periods of time, and the shoe is designed to protect it from moisture and transfer very little moisture in the event of rain, so sweat that is secreted can build up inside the shoe. To do. In addition to the breakdown of sweat, the components of sweat create a very unpleasant odor that is transmitted to socks, stockings or the feet themselves. Ordinary shoes for commuting to work or school are in such a situation every day, but sports shoes and rubber shoes are also in such a situation.

The odor is unpleasant, but sweating from the feet has an even worse effect. If you walk or run for a long time, wet shoes may blister more than dry ones, and even small scratches in wet areas may not heal easily. The fact that fungi grow very quickly in a humid and warm environment is also particularly offensive.

Many attempts have been made to prevent the unpleasant effects of perspiration on the feet. For example, it is also practiced to suppress sweating and neutralize an unpleasant odor by sprinkling powders or special chemicals on feet and shoes. Also used is an insole made of, for example, leather or cork, which is replaced with a new insole after a certain period of use, but is relatively expensive. An insole made of a foaming agent has also been proposed, and the insole can be washed so that it can be used for a long period of time, but is deformed during washing. Although athletic shoes can be machine washed, many people don't like to wash athletic shoes with other laundry, and there is little chance of washing several shoes at the same time, so one pair of shoes A lot of water, electric, to wash
The detergent is wasted. This washing method cannot be applied to leather shoes.

Insoles are known in the orthopedic art and are composed of two generally identically shaped partial soles, which are partially joined along their edges and between which there is a filling material. Is provided. The filler is generally made of a highly rigid metal or plastic component, and the partial sole is used to improve walking comfort and absorbs sweat generated from the foot. The purpose of this insole, also called an insert, is for shaping and not for hygiene.

[0007]

The above points relate only to the problem of perspiration of the foot, which is generally associated with heat. However, since the characteristic of the foot as the temperature sensor is exhibited not only at high temperature but also at low temperature, the foot becomes cold when it is cold. In order to prevent this, a few pairs of warm socks are sometimes worn at the same time, and shoes with a lining are also worn. However, such bulky wear is a limitation because it interferes with fast walking.

It has a practical and economical sole structure that absorbs sweat when it is hot, is hygienic and neutralizes odor, and is warm when it is cold, comfortable to wear in any environment, healthy, comfortable and practical. It is said that shoes do not exist.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the sole structure 1
1 shows a shoe 10 having an instep 1 and an instep 12, and a foot of a sole structure 11 (not shown) at a notched portion in the drawing.
The filling material 13 provided in the recessed portion 14 formed on the surface facing to is shown, and the filling material 13 is flat and flexible.

FIG. 2 shows another shoe 20, in which this sole structure 21 is provided with a detachable insole 24 as well as a fixing portion 23 connected to an instep 22. On the surface of the insole 24 facing the foot, recesses 28 and 29 having flat and flexible fillers 26 and 27 are formed at the heel portion of the foot or shoe and the ball portion.

The shoe 30 shown in FIG. 3 has a single-layer sole structure 31 in the shape of a foot, and a recess 32 in which a filler 33 is provided is formed. On the opposite surface 34 of the foot of the filler 33, adhesive 35 is applied in strips or in places.
Is provided to securely fix the filler to the recess 32, and when the effect of the filler 33 is lost, the filler can be easily removed from the recess 32. The size of the filling material 33 corresponds perfectly to the recess 32, and no beads or gaps occur at its side edges 36.

However, it is also possible to cut a considerably large filler with scissors or a knife to a predetermined size and use it. The thickness of the filler 33 completely corresponds to the depth of the recess 32, and the surface of the sole structure 31 that abuts on the foot (not shown) is completely flat and has no gap.

FIG. 4 shows a shoe 40 having an integrally formed multi-layer sole structure 41, in which several partial soles 41a, 41b, 41c are fixed to one another. A recess 42 is formed in the uppermost partial sole 41a, and a filler 43 is provided therein. The porous foil portion 4 is provided on the upper surface 44 of the filler 43 attached to the recess 42.
5 is provided, and the porous foil portion 45 is a filler 43.
Has an adhesive 47 that can be peeled off, and is fixed to the partial sole 41a by this adhesive.

Filler 4 as described with reference to FIG.
3 is joined to the sole structure 41 via the foil portion 45, and can be removed again after use. Since the foil portion 45 is thin, it does not interfere with comfortable walking. A thin cloth portion having adhesiveness on one side and having a filler 43 on the lower surface thereof can be used instead of the foil portion, whereby a structure similar to a bandage for first aid can be obtained.

FIG. 5 shows an insole 50, which has a recess 52 having a filling material formed on the surface 51 opposite to the foot thereof. This insole 50 has several layers 50a, 50b, 50c.
And the recess 52 is formed by removing a part of the lower layer 50c. With such a shape, the filler 53 does not come into contact with the sole of the foot, so that it is not so important to fit the filler 53 into the recess 52 exactly. The filling material has the structure shown in FIG. 3 or FIG.
It is fixed to the insole 50 similarly to the structure shown in FIG. The filler can be used with the insole 50 for any closed shoe that does not have a filler.

A similar insole 60 is shown in FIG.
Recesses 63 and 64 having fillers 65 and 66 are formed on both surfaces 61 and 62.

The filling material 70 shown in FIG. 7 and having a substantially foot shape is basically composed of a fleece. It is also possible to use cardboard, paperboard or cloth, the only point being that the filler is hygroscopic. The fleece contains a fragrance, which can be applied when the fleece is fluffy and is pressed in during the process of compacting into the fleece. This fleece-shaped filler 70 has a number of advantages. First, even if a foot sweats, the fleece absorbs it, so that the foot is dry and comfortable, and blisters are prevented. Second
In addition, the fragrance neutralizes the sweat-absorbing shoe material with an unpleasant odor during sweating. Further processing of the fleece with fungicides or bactericides can be used to prevent the exacerbation of athlete's foot and small wounds. While various scents can be imparted to the fragrance-containing filler, it is best to use only one scent for shoes. The filler can be marked with different colors depending on the scent. It is also possible to provide the side of the filling material which comes into contact with the foot with a certain shape, ie with ribs or grooves.
This allows the foot to be massaged during use, increasing comfort and improving circulation.

The opposite effect is obtained by using the filler 80 shown in FIG. The filling material 80 includes a flat bag 81 containing a material 82, and when the material 82 moves to each other or receives a pressure, an exothermic reaction occurs. The inside of the shoe can be heated by using such a material. Other functions are similar to those of the fleece-like filler.

Similar to the exothermic filler shown in FIG. 8, FIG.
It is also possible to apply the fleece-like filler shown in FIG. 6 to the insole shown in FIG. 6 at the same time. Some people sweat when their feet are cold, and such an arrangement is advantageous. When only one recess is formed in the sole structure, the fleece-like filling material and the exothermic filling material can be changed according to the season.

As shown in FIG. 9, a filling material, in particular a fleece-like filling material, is manufactured in the shape of a foot, and is distinguished, for example, from an air freshener container sold as an indoor or vehicle air purifier. You can also do it. FIG. 9 shows in detail a method of combining several fillers 90 into one block. As mentioned above, similar to bandages for first aid, the adhesive-bearing filling material is
It is necessary to supply it by putting it in a removable protective foil 91. The protective foils 91 can be bound together in a booklet or block form, and when the filler 90 is needed, it can be pulled out from the protective foil 91 and fixed to the recess from which the used filler has been removed. It is also possible for the fleece-shaped filler material itself with the protective foil to be fixed to one another along the side edges that are pre-drilled and cut off before use.

FIG. 10 illustrates a particularly preferred embodiment of the present invention, wherein the insole 100 illustrated therein is for coping with wear of the shoes under the ball of the foot. Insole 1
00 is basically composed of two identically shaped partial soles 101 and 102, one of which is made of a foaming agent and the other of which is made of a felting agent. Several holes 103 are formed in the partial sole 101,
A hole (not shown) is also formed in the partial sole 102. Most of the side edges of the partial soles 101 and 102 are joined to each other except a part, and the unjoined side edge portions 101a and 102a are partial soles 101 and 10.
Forming an insertion opening of the recess 104 defined by 2;
The filling material 105 is accommodated therein. Filling material 105
Consists of a combination of felts and papers that reinforce each other and is used as a support for fragrances for a long period of time, for example by forming it into a flap flap.

The fleece-like filler with fragrance and other activators can be supplied not only as an off-the-shelf product, but also as a large flat unit which the user can cut into the desired shape.

Although the fleece-like filler is basically considered a single-use or disposable item, it can also be made washable and may contain fresh fragrance and other active agents during or after washing. Can be granted.

The fleece-like filler may be packed in a plastic container to produce one having a particularly strong scent. This is for putting in shoes when you are not wearing them. In this case, by opening the plastic package and exposing the fleece-like filling material depending on the strength of the scent, it can be regenerated as a "puffy" shoe when not in use. By closing the plastic container again before putting on the shoe, the fleece-like filler can be used several times for this purpose.

The sole structure, the insole, and the filling material according to the present invention not only provide shoes with a good scent without the odor associated with sweating, but also increase the wearing comfort due to the sweat absorbing effect or the heat generating effect, and Hygiene has also been improved by using bactericides and bactericides. The use of the filler is simple, and the life of the shoe or insole is considerably increased, which is not only eco-friendly but also economical.

[0046]

Since the present invention is constructed as described above, it has the following effects. According to the first aspect of the present invention, the surface of the sole structure-not the sole, of course-is formed with a recess filled with a replaceable flexible filler. The size of the filling material is determined according to the recess so that the filling material fits perfectly into the recess. That is, using a filler that is too thin or too thick will cause the surface of the sole structure to become uneven, a bead will be formed using a filler that is too large, or a groove will occur if a filler that is too small is used. It shouldn't happen. The recess and thus the filler can be formed to extend to any part of the sole structure, and the provision of the filler improves the wearing comfort.

According to the second aspect of the present invention, a filler is used so as to cope with sweating of the foot, and the filler is provided on the foot ball where sweat glands are concentrated. It is also possible to provide several recesses and fillings adjacently.

According to the third aspect of the present invention, the surface of the sole structure provided with the recess may be the inner surface of the single-layer sole structure facing the foot. Since many inexpensive shoes, especially women's shoes, have a single-layer sole structure made of plastic, and therefore sweating and strong odor of the feet are strong, it is particularly desirable to use an insole for neutralizing the odor.

The recess may be formed in an integrally formed multi-layer sole structure provided on the contact surface with the foot.
This is especially desirable for athletic shoes and hiking shoes, where the use of an insole poses a high risk of slipping and blistering.

According to the fourth aspect of the present invention, the recess may be provided in the detachable insole which constitutes a part of the sole structure. Therefore, a shoe having a structure without a filler can be easily modified. The recess and the filling material can be provided not only on the opposite surface of the foot but also on the contact surface with the foot. If the recess and the filling material are provided on the opposite surface of the foot, the contact surface with the foot is flat and completely smooth, so there is no fear of blistering even if the filling material does not completely fit into the recess.

According to the invention described in claim 5, the concave portion can be formed by two adjacent partial soles of the insole,
It is also possible to partially fix the edge portion and insert a filler between them. It is particularly advantageous to combine two partial soles, one made of a foaming agent and the other made of a fleece such as felt. The two partial soles can also be opened.

When the insole is used, two recesses can be formed on both sides of the insole, and different infills can be filled.

According to the sixth aspect of the present invention, one or both of the contact surfaces is fixed in order to fix the filler in the recess.
For example, it may be wholly or partially self-adhesive by means of an adhesive or a Burley tape known under the name Velcro.

According to the invention described in claim 7, by filling the outer surface of the filling material with a porous foil or a cloth portion which is sticky on one side and extends beyond the edge of the filling material, the concave portion is filled. The material can be fixed. The action of this structure corresponds to that of a dressing for first aid. Of course, the foil or cloth can be used separately from the filler. In particular, copper has been evaluated as an insole material for various reasons, so perforated foils made of copper or having copper on the surface can also be used. It is better to provide a protective foil on the adhesive side of the foil or cloth that is removable until it is used. It is also possible to increase the size of the foil or cloth portion and cut and use the foil or cloth as needed.

According to the invention described in claim 8, it is made of a hygroscopic material such as paper, cardboard, fiber material, porous plastic or fleece in order to absorb perspiration from the foot especially in a warm environment. Fillers are used,
Fleece is particularly advantageous.

Fillers formed by combining felt and paper as felt-reinforced paper are particularly preferred.

According to the ninth aspect of the invention, by filling the filler with a bactericidal agent or a bacteriostatic agent, it is possible to prevent fungi against deterioration of small scratches.

According to the tenth aspect of the present invention, the unpleasant odor can be neutralized by filling the filler with a long-lasting fragrance. It is especially advantageous to press the fragrant material into the fleece by putting the fragrance into the raw cotton-like base material of the fleece and then pressing to form the fleece. The above-mentioned felt-reinforced paper fillers are particularly advantageous as fragrance supports. There are various scents, but it is preferable to use only one scent for shoes.

If the surface of the insole that comes into contact with the foot is formed into a shape such as a rib or a small hump, it acts as a kind of foot massage that improves circulation.

According to the eleventh aspect of the present invention, by using the filler having a flat bag and containing the materials which generate an exothermic reaction when they move to each other or when pressure is applied, warm shoes even in cold weather. Can be obtained. Although large in size, such bags have traditionally been used to keep hands warm in gloves and outer pockets.

Even if the foot is cold, sweat may occur from the foot. Therefore, as described above, a fleece-like material having concave portions on both sides and absorbing sweat and containing an aromatic is provided on the contact surface with the foot. It is also possible to use a sole structure having an insole provided with a bag-shaped filling material that generates heat on the opposite surface of the foot. Two fillers having different functions can be provided adjacent to each other to give the desired dual effect to a shoe without an insole.

According to a twelfth aspect of the present invention, the insole for sole structure of shoes comprises a plurality of partial soles, and the fleece-like filling material is provided with a recessed portion which is exchangeably joined. The filler contains a fragrance. The insole, the recess and the filling material are provided at the foot ball portion, and the insole has a multi-layered structure and the filling material is provided between two layers. Although this insole can be made to the size of a normal shoe, it has edges that can be cut, so it can be fitted to shoes of any shape by cutting the edges without damaging the insole. .

Further, as in the invention described in claim 13, it is also possible to constitute by two partial soles having substantially the same shape, and the concave portion for accommodating the filling material can be limited by the partial soles. Can be adapted.

According to the fourteenth aspect of the present invention, the shoe sole structure filler is formed into a fleece shape to impart hygroscopicity, aromaticity and self-adhesiveness, so that the shoes having the filler are comfortable to wear. It can be improved and can be worn on any shoe as needed.

It is also possible to sell the replaceable filler in the form of an easy-to-use set of at least two easy-to-wear pieces. The protruding edges of the removable protective foil of the individual pieces themselves or of their adhesive side can be joined together in sheet or block form.
