Insoles and footwear for footwear

Technical field

[0001] The present invention relates to an insole for footwear and footwear. Specifically, it relates to insoles for footwear and footwear that suppress body distortion and improve the health of the wearer.

Background art

[0002] With increasing health consciousness, foods and utensils that satisfy the needs of people who have been healthy nowadays have been released, but as such utensils, for example, magnetism is generated at the bottom. A magnet is attached, or the bottom is made of a material that emits negative ions, and sandals and shoes that promote blood flow by the action of magnetism and negative ions, or protrusions on the bottom facing the sole Examples include sandals and shoes that stimulate the pressure points on the soles of the feet and promote blood flow.

[0003] However, a material that emits negative ions generally requires a structure that is coated with a thick coating material in order to protect the material that emits negative ions whose strength is weak. Therefore, many negative ions are thick and blocked by the covering material, and a sufficient amount of negative ions is difficult to be released to the sole. In addition, the soles are less likely to be absorbed into the body due to the thicker skin compared to other parts.

[0004] Therefore, various techniques for absorbing a sufficient amount of negative ions into the body of a wearer of footwear have been proposed (see, for example, Patent Document 1). FIG. 3 (b) is a schematic view for explaining the structure of the upper part of the conventional sandal, while the conventional sandal 101 is shown in FIG. There is provided a bottom portion 102 that comes into contact with, and an upper portion 103 that is attached and fixed to the upper side of the bottom portion 102 and comes into contact with the instep. The upper part 103 includes an exterior sheet 104 that protects the outside of the sandal 101, an interior sheet 106 that has a plurality of holes and that contacts the instep, and the exterior sheet 104 and the interior sheet 106. It is provided so as to be sandwiched between the two and the negative sheet 105 made of tourmaline or Bincho charcoal. As a result, the thin toe strength of the skin absorbs a sufficient amount of negative ions. [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2002-233402

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention. FIG. 1 is a schematic diagram showing an example of a front side (a) and a back side (b) of an insole for footwear to which the present invention is applied.

Here, the insole 1 for footwear of the present invention includes an ethylene butyrate (EVA) sponge layer (an example of a first elastic layer) 7 and a low resilience urethane layer laminated on the EVA sponge layer 7 ( This is an example of the second elastic layer.) 6 and laminated on the low resilience urethane layer 6 and fire And a woven fabric fabric (an example of a bioactive material layer) 8 in which a mineral composition containing mountain stone, germanium, and barleystone is mixed. The insole 1 for footwear has a heel region 3 that is in contact with the heel of the foot, and the heel region 3 includes an outer force heel region 3A and an outer force heel along the outer shape of the force heel region 3. The region 3A is composed of an inner force heel adjacent to the region 3A and the region 3B, and the outer force heel region 3A is composed of a sponge layer 5 having a substantially U-shaped shape. Further, the inner force heel region and other regions at the bottom are made of a low-resilience urethane layer 6, and the sponge layer 5 is made of a softer material than the low-resilience urethane layer 6. A vent hole 10 is formed.

[0023] Also, as shown in FIG. 1 (b), a plurality of foot sizes such as 230-255 mm (23-25.5 cm) are displayed on the back of the insole 1 for footwear to which the present invention is applied. A linear size display means 11 is provided and a vent hole 10 is formed. Here, the insole 1 for footwear can be cut along the size display means 1 1. In FIG. 1 (b), the size of the insole 1 for footwear is 255 mm (25.5 cm). .

Here, as long as the sizes of a plurality of legs can be displayed, the size display means does not necessarily have to be linear. For example, the size display means may be composed of regions of different colors for each size.

As shown in FIG. 1 (a), the lowermost layer of the insole 1 for footwear is an EVA sponge layer 7, and a low-resilience urethane layer 6 is laminated over the entire upper surface of the EVA sponge layer 7. In the low resilience urethane layer 6, a sponge layer 5 having a substantially U-shaped shape is laminated on the outer force heel region 3 A along the outer shape of the force heel region 3.

[0025] Further, the surface with which the sole of the insole 1 for footwear comes into contact contains 85% by mass of volcanic stone, 5% by mass of germanium, 5% by mass of barley stone, and 5% by mass of tourmaline powder based on the total amount of the mineral composition. It consists of woven fabric 8 mixed with mineral composition. Further, a germanium chip 9 is embedded on the surface of the insole 1 for footwear that contacts the sole.

[0026] Here, a woven fabric is described as an example of the base of the bioactive material. However, it is not always necessary to use a woven fabric as long as it can contain a mineral composition. Leather fabrics, non-woven fabrics, etc. may be used as the substrate.

[0027] Here, the force heel region is composed of an outer force heel region along the outer shape of the force heel region and an inner force heel region adjacent to the outer heel region, and the outer force heel region is the inner side. Or The outer heel area does not necessarily have to be composed of a sponge layer having a substantially U-shape, and is not necessarily on the EVA sponge layer. There is no need to laminate a low-resilience urethane layer, for example, the EVA sponge layer can be changed to a low-resilience urethane layer, or the low-resilience urethane layer can be changed to a ponge layer.

[0028] In addition, the force heel region is composed of an outer force heel region along the outer shape of the force heel region, an inner force heel region adjacent to the outer heel region, and whether the outer force heel region is the inner side. Because it is composed of materials that are softer than the force and area, the surface with which the soles of the insole for footwear come into contact must be composed of a woven fabric mixed with a mineral composition. Also, the surface where the sole of the insole for footwear comes in contact does not necessarily have a germanium chip embedded.

Further, if the mineral composition contains volcanic stone, germanium, and barleystone, tourmaline powder may not necessarily be contained. The ratio of each component is 85% by weight of volcanic stone, germanium 5 It may not be 5% by mass and 5% by mass of barley stone.

FIG. 2 is a schematic view showing an example of footwear to which the present invention is applied.

Here, the sandal 1A of the present invention includes a bottom portion 2 that supports a foot, and an upper portion 4 that is located above the bottom portion and contacts the instep. Also, the bottom 2 has a heel region 3 that comes into contact with the force heel of the foot, and the force heel region 3 has an outer heel region 3A along the outer shape of the force heel region 3 and an outer force heel region. The inner cover and the region 3B are adjacent to 3A, and the outer cover and the region 3A are formed of a sponge layer 5 having a substantially U-shape. Further, the inner cover area and the other areas at the bottom are made of a low-resilience urethane layer 6, and the sponge layer 5 is made of a softer material than the low-resilience urethane layer 6.

[0030] As shown in FIG. 2, the lowermost layer in contact with the ground of the bottom 2 is an outsole layer 7A made of rubber, and a low-resilience urethane layer 6 is laminated over the entire upper surface of the outsole layer 7A. In the low resilience urethane layer 6, a sponge layer 5 having a substantially U-shape is laminated on the force heel region 3 A along the outer force heel region 3 A along the outer shape of the region 3.

[0031] Further, the surface with which the soles of the bottom part 2 come into contact contains 85% by mass of volcanic stone, 5% by mass of germanium, 5% by mass of barleystone, and 5% by mass of tourmaline powder based on the total amount of the mineral composition. It consists of a woven fabric mixed with a mineral composition. The upper portion 4 is composed of two pieces extending from the bottom portion 2, and a surface fastener 8A is attached to the surface of each piece so that the upper portion 4 can be opened and closed. In addition, on the inner surface of the upper portion 4 that contacts the instep, sponge urethane that is soft to the touch is used. Further, a germanium chip 9 is embedded on the surface of the bottom 2 where the sole contacts.

[0032] Here, the force heel region is composed of an outer force heel region along the outer shape of the force heel region and an inner force heel region adjacent to the outer heel region, and the outer force heel region is the inner side. The outer heel area does not necessarily have to be formed of a sponge layer having a substantially U-shape, and is not necessarily out of rubber. For example, the rubber outsole layer may be changed to a low resilience urethane layer, and the low resilience urethane layer may be changed to a rubber layer similar to the outsole layer. You can change it.

[0033] Further, the force heel region is composed of an outer force heel region along the outer shape of the force heel region, an inner force heel region adjacent to the outer heel region, and whether the outer force heel region is the inner side. If it is made of a material softer than the force and the area, the upper part does not necessarily have to be composed of two pieces extending from the bottom part. The surface with which the sole of the bottom contacts is not necessarily made of a woven fabric mixed with a mineral composition, and the germanium chip is not necessarily embedded in the surface with which the sole of the bottom contacts. Well ...

[0034] Further, the present invention will be described by taking sandals as an example. However, sandals are not necessarily used for footwear, and sneakers, boots, business shoes and the like may be used.

[0035] Thus, since the insole for footwear and footwear of the present invention is made of a material whose outer heel region is softer than the inner heel region, the outer heel region is adapted to the wearer's heel, It prevents and stabilizes the force heel from side to side, suppresses body distortion and stabilizes posture. The outer heel area is a sponge with a substantially U-shaped shape. Since it consists of layers, the outer force heel area can be adapted to the wearer's force heel.

[0036] Further, since the mineral composition containing volcanic stone, germanium and barley stone is mixed in the insole for footwear of the present invention and the bottom of the footwear, the smell of the foot is removed and the growth of bacteria is suppressed. Can prevent diseases such as athlete's foot and eczema, activate blood by improving blood circulation, and can adjust the balance of the whole body with the power of negative ions.

[0037] In addition, since the insole for footwear of the present invention and the bottom of the footwear are composed of a low-resilience urethane layer, it is possible to absorb the impact on the knees and waist while walking and reduce the burden. Moreover, since the footwear of the present invention stabilizes the posture and absorbs the impact, comfortable walking can be realized.

[0038] In addition, since the upper part of the footwear of the present invention can be opened and closed, it is easy to put on and take off immediately for a person who has injured an instep or a person with a foot injury.

[0039] In addition, since the insole for footwear and footwear of the present invention has a germanium chip embedded in the surface in contact with the sole, the pot on the sole is stimulated every time the wearer walks, so It detoxifies and excretes toxins that have been ingested, restores the body's original power, normalizes the body's functions, improves metabolism, and restores healthy body and beautiful skin.

[0040] In addition, the insole for footwear of the present invention is provided with size display means for displaying the sizes of a plurality of feet and is separable along the size display means. Can be cut and used together.
