Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole for footwear, and more particularly to an insole for footwear such as a shoe pad.

[0002]

2. Description of the Related Art FIG. 5 is a plan view of a conventionally known shoe pavement, and FIG. 6 is a sectional view thereof. A liquid storage chamber 10 is provided inside the shoe bed, and the liquid storage chamber 1
There is water W in 0. Since the shoe pad is made of a flexible material, when the person's foot F (shown by the alternate long and short dash line in FIG. 5) is placed on the shoe pad, the water W in the liquid storage chamber 10 is reached.
Moves, and the upper surface of the shoe sole deforms so as to match the shape of the sole of the foot F. Therefore, if this shoe pad is laid on the insole of the shoe, the foot F fits the shoe pad when the shoe is worn, and the comfort of the shoe is improved.

[0003]

However, during walking, the balance of the force received by the shoe sole changes momentarily with the movement of the center of gravity of the person, and as a result, the shoe sole conforms to the shape of the sole of the foot F. I will change the shape as I do. When the shape of the shoe sole changes, firstly, the weight balance of the shoe sole changes. For example, when the center of gravity of a person moves from the heel side toward the toe side, the water W moves from the toe side toward the heel side in the liquid storage chamber 10. Therefore, the center of gravity of the shoe sole moves from the toe side toward the heel side (that is, in the direction opposite to the moving direction of the center of gravity of the person). Secondly, the shoe pad prevents the shoe from following the movement of the foot F, and the sense of unity between the foot F and the shoe is impaired. For example, even if the heel of the foot F is raised, the water W moves from the toe side to the heel side in the liquid storage chamber 10, so that the heel of the shoe is hard to rise. As described above, the shoe pad shown in FIG. 5 has a problem that it is difficult to walk. Further, when the shoe sole is made of a rigid and hard material, it is difficult to fit the entire sole of the foot, and the effect as a liquid-embedded shoe sole is diminished.

The present invention has been made in view of this point, and an object thereof is to provide an insole for footwear which is comfortable to wear and easy to walk.

[0005]

In order to achieve the above object, the insole for footwear according to the present invention comprises a plurality of liquid storage chambers formed of flexible members so as to individually store liquids. It is characterized by having.

It is preferable that a member for injecting a liquid is provided in the liquid storage chamber. For example, the member may be made of an elastic material that allows the needle to pass through but restores liquid leakage when the needle is removed. Further, it is preferable that the liquid storage chamber of the portion that contacts the arch is provided with the liquid so that the liquid storage chamber is higher than the other liquid storage chambers.

[0007]

According to this structure, since the plurality of liquid storage chambers are provided so as to individually store the liquids, the liquids are stored in the liquids even if the balance of the force applied to the insole changes. You cannot move between rooms. As a result, the weight balance of the insole does not change and the sense of unity between the shoe and the foot is not impaired. Further, since the liquid storage chamber is formed of a flexible member and the liquid in the liquid storage chamber has fluidity, the liquid storage chamber has a shape that matches the shape of the sole of the foot in the range where each of the soles of the feet hits. Change the shape so that.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a shoe sole having an insole for footwear according to the present invention will be described with reference to the drawings. Conventional example
(FIGS. 4 and 5) and the same or corresponding portions between the embodiments are designated by the same reference numerals and detailed description thereof will be omitted.

In the embodiment shown in FIGS. 1 to 3, three liquid storage chambers 1 are formed of flexible members (for example, members made of materials such as plastic and rubber) so that liquids can be stored individually. Have three. Injection members 11 to 13 for injecting the liquid are provided on the side surfaces of the liquid storage chambers 1 to 3. The injection members 11 to 13 are the injection device S.
It is made of an elastic material (for example, a material that returns to its original state such as raw rubber) that allows the liquid to leak when the needle is pulled out, but does not leak when the needle is pulled out.

The upper surface of the shoe cloth is flat in the normal state where the liquid is not contained in the liquid storage chambers 1 to 3 (FIG. 2), but the liquid is stored from the injection members 11 to 13 by the injection device S. When water W is injected into the chambers 1 to 3, it rises and rises (Fig. 3). Therefore, when the liquid storage chambers 1 to 3 are used, the feet F
So that the height matches the uneven shape on the back of the
(So that the liquid storage chamber 2 of the part of the foot F that touches the arch Fa is higher than the other liquid storage chambers 1 and 3), and that the thickness of the bedding fits the size and shape of the shoe, Inject W.

The positions at which the injection members 11 to 13 are provided are not limited to the side surfaces of the liquid storage chambers 1 to 3. When it is provided on the side surface side, there is an advantage that it is difficult to directly receive the force from the foot F. For example, when it is provided on the upper surface side or the lower surface side of the liquid storage chambers 1 to 3, the injection needle of the syringe S is a member for injection. 11-
13 has the advantage that it is easy to stab. In particular, when it is provided on the upper surface side, it is possible to inject the water W even in the state where the shoe pad is set in the shoe.

Since the three liquid storage chambers 1 to 3 are provided so as to individually store the water W, even if the balance of the force applied to the shoe pad changes, the water W will remain in the liquid storage chambers 1 to 1. Three
I can't move between them. As a result, the balance of the weight of the shoe sole does not change, and the sense of unity between the shoe and the foot F is not impaired. Therefore, the effect of easy walking is obtained.

Further, since the liquid storage chambers 1 to 3 are formed of a flexible member and the water W in each of the liquid storage chambers 1 to 3 is fluid, a person's foot F is placed on the shoe pad. Is shown in Figure 3.
As shown in, the water W moves in each of the liquid storage chambers 1 to 3,
The upper surface of each of the liquid storage chambers 1 to 3 is covered by the foot F
Change the shape to match the shape of the back of the. Therefore, if this shoe pad is laid on the insole of the shoe, the shoe pad fits the foot F when the shoe is put on, and good comfort is obtained.

Although the water W cannot move between the liquid storage chambers 1 to 3 as described above, the injection members 11 to 13 for injecting the water W into the liquid storage chambers 1 to 3 are provided. Therefore, by adjusting the height of each of the liquid storage chambers 1 to 3 as described above, it is possible to make a shoe sole according to the shape of the sole of the foot F of the user. As a result, the upper surface of the shoe sole can be made to match the shape of the sole of the foot F as a whole,
In addition, even a large shoe can be fitted to the foot F.

Since the water W is contained in the liquid storage chambers 1 to 3, a comfortable feeling can be obtained on the sole of the foot F due to a temperature difference between the water W and the foot F. Moreover, since each of the liquid storage chambers 1 to 3 is formed of a flexible member as described above,
The force when the water W moves in each of the liquid storage chambers 1 to 3 is easily transmitted to the sole of the foot F. Therefore, the stimulation applied to the sole of the foot F due to the movement of the water W also has an effect of positively affecting health.

Instead of the water W, another liquid is added to the liquid storage chambers 1 to 1.
3 may be injected. For example, the temperature of the foot F can be kept more stable by using a liquid having a large specific heat. Further, by adjusting the balance of the weight of the shoe stock by using a liquid having a high viscosity to some extent, it is possible to improve the ease of walking according to each person.

FIG. 4 shows another embodiment according to the present invention. In the embodiment shown in FIG. 4, the liquid storage chamber 2 is replaced by the liquid storage chambers 4,
The structure is the same as that of the embodiment shown in FIGS. 1 to 3 except that it is divided into two parts. If the liquid storage chamber 2 is divided into smaller pieces in this manner, the weight balance of the shoe pavement is further improved, which makes walking easier. In order to make the liquid storage chambers 4, 5 conform to the shape of the sole of the foot F, the arch F
The height may be adjusted so that the liquid storage chamber 5 corresponding to a is higher than the liquid storage chamber 4 corresponding to the outer portion of the arch Fa.

Further, the liquid storage chambers 1 to 5 may be further divided into a plurality of portions (for example, a honeycomb shape). If the liquid storage chamber is divided into smaller pieces, the weight balance of the shoe pavement is further improved, which makes walking easier. In that case, the injection member of the liquid storage chamber that does not face the side surface of the shoe cloth may be provided on the lower surface side of the liquid storage chamber.

[0019]

As described above, according to the insole for footwear according to the present invention, each of the plurality of liquid storage chambers formed of a flexible member so as to individually store the liquid can contact each other. Since the shape is changed so as to match the shape of the sole of the foot within the range, good wearing comfort is obtained, and further, since there is no movement of the liquid between the liquid storage chambers, it is easy to walk.

By providing a member for injecting the liquid into the liquid storage chamber, it is possible to obtain an insole for footwear according to the shape of the sole of the foot of the user. Pass the needle,
By providing a member made of an elastic material that restores the liquid so as not to leak when the injection needle is pulled out, the height of each liquid storage chamber can be adjusted by the injection device. For example, it is possible to inject the liquid so that the liquid storage chamber of the portion that contacts the arch is higher than the other liquid storage chambers.
