Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an insole laid on the sole of a shoe, and more particularly to an insole suitable for promoting health.

[0002]

[Prior art]

 Conventionally, leather or synthetic resin insoles have been widely used for shoes, but recently, the whole is meshed or many small holes are made to improve ventilation and deodorant properties. Insoles made of antibacterial materials are mainly used.

[0003]

[Problems to be solved by the device]

 By the way, this type of insole is mainly deodorant and antibacterial, but the basic shape is the same as the conventional insole, and the whole is flat. Therefore, it was not possible to give a massage effect or a pleasant stimulus to the uneven sole due to the presence of the arch, and it was also impossible to improve health through the foot. The present invention has been made in view of the above problems, and an object thereof is to provide an insole that can contribute to health promotion by massaging the sole of the foot by walking.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the insole of the present invention encloses a gel consisting of pharmacopoeia glycerin in a sheet-like bag in which two sheets of insole-shaped polyurethane sheet are put together and the outer peripheral portion is fused. It will be. Further, in the above structure, an extension portion is integrally formed on the toe side of the sheet-like bag body, and the extension portion is provided with a plurality of cutting lines set to dimensions corresponding to a plurality of shoe sizes. Further, in the above-mentioned configuration, a flow system stop portion for suppressing the flow of fluid is provided substantially at the center of the sheet-like bag body.

[0005]

[Action]

 According to this invention, the insole is formed by encapsulating a gel consisting of pharmacopoeia glycerin in a sheet-shaped bag body, so when this insole is laid on the sole of the shoe, it is added to the sheet-shaped bag body by stepping on it. The internal gel absorbs the pressing force. At this time, since the gel is gelatinous, it flows in the sheet bag according to the pressing force and deforms the sheet bag according to the unevenness of the sole. Due to this deformation, the force of rubbing the sole acts and massages the foot. In addition, since the extension part that is integrally formed on the toe side of the sheet-shaped bag has multiple cut lines, you can cut the tip from these cut lines according to the size of the shoe, and the shoes will not interfere. A sheet-like bag can be inserted into and laid on the sole of the shoe. Further, since the flow system stop portion provided at the substantially center of the sheet-like bag body suppresses the flow of gel, the pressing force applied to the sheet-like bag body is equalized and the sheet-like bag body is prevented from being rapidly deformed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the overall structure of the insole according to the present embodiment, and FIG. 2 is a vertical sectional view of the same insole. This insole is a sheet-shaped bag body 1 in which gel J is enclosed, and an extension portion 6 for adjustment is integrally formed so as to be compatible with various shoe sizes. The sheet-shaped bag body 1 is formed in a bag shape by using two sheets of polyurethane sheet cut into the shape of an insole forming a shoe sole. In this example, the insole for the right foot will be described, but the upper surface side polyurethane sheet 2 is curved regardless of the size, and the lower surface side polyurethane sheet 3 is substantially flat so that the upper surface side 2 can be freely deformed. In addition, it is slightly larger than the lower surface side 3.

The upper and lower polyurethane sheets 2 and 3 are formed with left and right long holes 4 and 5 extending in the lengthwise direction centering on the arch 1c. On the heel 1b side of the upper surface side polyurethane sheet 2, a small hole (not shown) for injecting gel J is previously formed. When the high-frequency welder is applied to the upper and lower polyurethane sheets 2 and 3 with the outer peripheral edge and the peripheral edges of the respective long holes 4 and 5 joined, the outer peripheral portion 1d is fused and both long holes 4 , 5 are fused together at their peripheral portions to form a sheet-like bag body 1 having two flow system stoppers 4a, 5a at substantially the center. At this time, the flat extension portion 6 is integrally formed by fusion-bonding the entire heel 1b side, which is ahead of the curve connecting the little ball side A and the little ball side B of the foot.

With reference to the curved base end of the extension portion 6, a distance corresponding to the size of three kinds of shoes is provided between the top end side polyurethane sheet 2 and the bottom side 3 toward the front end. When it is heated and melted in the shape of a curved line, three recessed grooves are formed in the extending portion 6 and cut lines 6a, 6b, 6c which are easily separated are provided. Then, the gel J is injected into a small hole provided on the heel 1b side of the upper surface side polyurethane sheet 2, and a high-frequency welder is applied to the periphery of the small hole to seal the gel J. In addition, this gel J is a pharmacopoeia glycerin based on the Japanese Pharmacopoeia and is manufactured by NOF Corporation.

The insole thus formed can be inserted into a shoe and laid on the sole of the shoe by cutting the cut lines 6a to 6c in accordance with the size of the shoe at the time of use. Then, when the user wears shoes with this insole and walks, the gel J inside absorbs the pressing force applied to the sheet-like bag 1 by the stepping on of the insole. Therefore, the shoes are comfortable to wear and the feel on landing is also good. Further, since the gel J is gelatinous, it flows in the sheet-shaped bag 1 according to the pressing force, and the sheet-shaped bag 1 is deformed according to the unevenness of the sole. Due to such deformation, the force of rubbing the sole of the foot acts each time the user walks, and the foot is massaged.

Furthermore, since the two elongated flow stop portions 4a and 5a provided in the approximate center of the sheet-like bag body 1 suppress the flow of the gel J, the pressing force applied to the sheet-like bag body 1 is made uniform. The sudden deformation of the bag 1 is suppressed. Therefore, the sheet-like bag 1 fits on the sole of the foot to give a pleasant stimulus while protecting the natural shape of the foot, and it is possible to trim the toes. In addition, since the sheet-shaped bag 1 is formed of the polyurethane sheets 2 and 3 in this insole, it does not have the odor peculiar to shoes and is excellent in deodorizing property. In addition, since it is easy to wash, it can be kept clean and has an antibacterial effect.

[0011]

[Effect of device]

 As described above, according to the present invention, when the insole is laid on the sole of the shoe, the gel inside absorbs the pressing force due to the stepping and absorbs the shock, and the gel flows and the sheet-like bag body is closed. As it deforms, the force of rubbing the soles of the feet acts and massages the foot, which has the effect of improving health. In addition, by cutting the tip from the cutting line provided on the extension of the sheet-shaped bag body according to the size of the shoe, it can be laid on the sole of the shoe, so a single insole can accommodate various shoe sizes. There is also an advantage that can be done. Further, the flow system stop portion suppresses the flow of gel, equalizes the pressing force applied to the sheet-like bag body, and suppresses the rapid deformation of the sheet-like bag body, so that the sheet-like bag body fits on the sole of the foot and the foot is closed. There is also the effect that it can give a pleasant stimulus while preserving its natural shape.
