Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe insole and a fishing type, and more particularly, to a foot walking mechanism which alternates between the left and right legs of a shoe wearer without disturbing the original walking function of the foot. The present invention relates to a shoe insole and a fishing type which are useful for promoting the above.

[0002]

2. Description of the Related Art Conventionally, the inventions relating to insoles for shoes have been relatively aimed at alleviating the impact against the intense footwork of sports shoes. Town shoes for general walking, in particular, the cause of injury of the foot such as hallux valgus. Surprisingly few improvements have been made to accommodate women's leather shoes. Under such circumstances, Japanese Patent Publication No. 1-42681 and Japanese Utility Model Publication 6-25
No. 127 publication is available.

The former is an invention aimed at improving the cushioning effect on the foot and the arch supporting effect by incorporating two kinds of hard and soft cushioning pieces inside the foot arch. The latter is a device intended to improve comfort by cutting or indenting the insole corresponding to the little finger of the foot to reduce pressure on the little finger due to the instep and reduce deformation and injury of the little finger. .

[0004]

Since the town shoes for general walking are also foot wear, it is natural to pursue fashionability. However, there seems to be a flow of manufacturing without understanding the structure and motor function of the half-faced foot.

"The seven bones of the tarsal part are thick and stubborn, and the joints are in close contact with each other so that the weight is firmly received. The five bones of the middle foot part are long and thin and spread toward the tip. It exerts the spring effect of propagating the stress of forward. The 14 bones of the toe are small and suitable for grasping the ground. ”(Professional shoe f
Itting American Shoes Retailers Association Japan Shoes Co., Ltd.) Foot foot with such a structure and characteristics
Then, the problem to be solved here is as follows.

[0006] First, in the forefoot, the phalanges are the attachment points for 14 bones, 9 joints, as well as about 16 flexors and extensors. Plays press and hold. In addition, the five metatarsophalangeal joints perform dorsiflexion, plantar flexion and medial and abduction of the fingers. In order to emphasize the appearance of the shoe, the forefoot, where various organs that play an important role in upright walking of the foot are arranged, is narrow in width and low in height. Can be made more relaxed in a way that does not impair the physical properties of the wearer, otherwise it may interfere with the achievement of those physiological functions, and the damage around the phalanges of the wearer may not be reduced. I'm afraid.

Secondly, it seems that there is a strong tendency in the rear foot to soften the contact condition between the shoe and the foot, probably because it improves the comfort of the feet. For example, a footbed made of a foamy soft cushion material is stretched on the upper surface of the insole, or an arch pad or an arch cushion is attached to the arch of the foot with a similar material. However, as the material becomes thinner while wearing it, or the place where it is attached is not suitable, the foot may move in the shoe, the fingertip may be damaged, and a friction part may be formed on the sole. There seems to be many. In general leather walking shoes without strong tightening means such as sports shoes, especially women's shoes, it is necessary to construct the insole so that the foot can capture the shoes well.

Third, there is a problem of weight bearing in the metatarsophalangeal joint. It seems that I often heard and commented on the explanation that the 1st and 5th metatarsophalangeal joints together with the calcaneal protuberance make up three points of weight support. However, the main function of the metatarsophalangeal joint is dorsiflexion and plantar flexion of the foot, and its form is a ball joint, and its movement is large up, down, front and back. That is, the joint is not a device that closely adheres to the weight load, unlike the tarsal part. If the burden is constantly applied, the fatigue of the joint capsule and the ligament that reinforces the joint capsule may occur only in a portion where the movement is large, resulting in subluxation of the ball, that is, hallux valgus.

[0009]

In order to solve the above-mentioned problems, the present invention is an insole which is joined in a state of being superposed on a grounded sole extending from the heel portion to the foot portion of a shoe, and is thick. A laminated plate made by bonding a thin cellulosic fiber board to the lower side of a cork particle compression plate or a rigid plate having the same effect as this, and the cutting line at the front end thereof is the first middle of the sole of the wearer. From the posterior medial side of the neck of the foot to the posterior lateral side of the fifth metatarsal head
Is there a lateral elliptical through hole that has a "f" -shaped anterior line that obliquely passes through the posterior constriction of the metatarsal head and accepts a part of the calcaneal ridge overhang of the heel part? Or, instead of this, cut the second half insole cut in a horizontal line at the position of the hole, and previously cut the entire length from the heel to the toes with a laminated plate of the same configuration, After the shank is embedded in the lower rear part to cover the backer board, the second half insole is adhered to the upper surface of the second half of the body of the insole that has been stiffened to produce an insole for shoes integrally formed. .

Further, the present invention is an insole which is removably laid along a fixed insole in a shoe, and is a thin cork grain compression plate or a thin plate below a rigid plate having the same effect. With a laminated plate formed by adhering cellulose fiberboard, the cutting line at the front end thereof extends from the posterior medial side of the first metatarsal condyle of the foot sole of the wearer to the posterior lateral side of the fifth metatarsal condyle. "He" that passes diagonally behind all condyle head constrictions
A lateral oval through hole with a V-shaped front end line that accepts a part of the calcaneal bulge overhanging part of the heel part, or alternatively, a rear end that is cut in a horizontal line at the position of the hole Produce a shoe insole with a line.

Further, the present invention is a fishing type for fishing the upper of the shoe with the insole for a shoe, wherein the front end of the "-" shape of the middle insole of the rear half of the bottom of the foot is fitted. As described above, a fishing type having a bottom surface that projects downward with its forefoot portion having an inverse step of the thickness of the rear half insole is used, and this is used.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The insole for shoes proposed here is manufactured in the following manner, for example, as shown in FIGS. 1 and 3 (A) (B) (C). First, for example, a cork grain compression plate having a thickness of 2.3 mm or a rigid plate 1 having the same effect as the compression plate 1
The laminated board 1 is formed by adhering the cellulose fiber board 1b having a thickness of 0.7 mm to the lower side of a, and the cutting line S at the front end of the laminated board 1 is the first of the soles of the wearer shown in FIG. Metatarsal head constriction posterior medial side P1 to fifth metatarsal head constriction posterior lateral side P
Up to 5, all metatarsal head constrictions posterior P1, P2, P3
A lateral wide elliptical through hole 1c having a front end line S'having a V-shape that obliquely passes through P4 and P5 and receiving a part of the calcaneus bulge protruding portion (not shown) of the heel part In the latter half of the shoe, which is provided with a rear end line T that is cut or formed in place of the through hole 1c in a horizontal line at the front side of the hole 1c, and the rear part from the rear end line T is a cutout part 1c '. Laminated plate 2 in which bottom 10 is cut and attached, and in advance, the same structure as that described above, that is, cork grain compression plate or rigid plate 2a having the same effect, is bonded with cellulose fiber board 2b.
Cut the entire length from the heel to the toes with the above, and after embedding the shank 2c in the lower rear part to cover the backer board 2d, on the upper surface of the latter half of the insole body 20 that has been stiffened, this second half An insole 30 for shoes is produced by integrally bonding the insole 10 of the part.

When fishing the upper with the insole 30 for shoes, as shown in FIG. 4, the bottom surface 40a of the fishing tackle 40 and the upper surface of the insole are in the shape of a letter "S", which is a step S of the insole. Since it is fitted with, the front from the relevant line S ″ in the fishing die 40 is
The fishing type is provided with the bottom surface 40b of the forefoot portion protruding downward at the reverse step having the same dimension as the thickness of the insole step.

Further, in the final step of shoe manufacturing, the insole is not covered with general leather shoes for the purpose of improving the foot contact by sticking a soft leather covering on the entire upper surface. Of course.

[0015]

EFFECTS OF THE INVENTION According to the insole for shoes of the present invention, the uneven shape of the upper surface of the insole is as follows. The convex surface of the entire arch of the foot that draws the arc up to the next, then it falls at the step and becomes a concave surface of the forefoot up to the tip of the foot so that it fits with the uneven shape of the bare foot, so the floor reaction force from below is effective It acts to strengthen the shoe holding power of the foot, reducing the mechanical loss of walking forward and making the foot lighter.

The shoes produced by fishing in the insole are
It is possible to add a new space up to about 3 mm x the total area of the forefoot sole to the forefoot. Therefore, various organs of the forefoot such as the phalanges, flexors, extensors, metatarsophalangeal joints are released from unnatural compression, and can perform their original functions.
At the same time, the damage around the phalanges of the wearer can be greatly reduced. Moreover, this increase in volume is inconspicuous in appearance, and can be realized with almost no loss in terms of fashion.

On the other hand, in the rear foot, the material is not a flexible material but a cork grain compression plate which is an elastic material having high rigidity, and a laminate with a flexible and flexible cellulose fiber board is bonded in two steps, Due to the extremely reinforced structure backed by a shank, the floor reaction force acts strongly on the entire arch of the foot from the calcaneal protuberance to the metatarsal constriction, forming a zone that plays the main role of weight support. Naturally, the spring effect of the five metatarsal bones is increased, and the weight load on the forefoot including the metatarsophalangeal joint is greatly reduced, so that the injury of the forefoot caused by an unreasonable weight burden can be avoided.

In addition, a cork grain compression plate rich in elasticity having a property of appropriately stimulating the flexible muscles of the wearer's sole itself and a laminated plate of supple and refracting cellulosic fiber board are applied to the sole of the foot. The compression force applied repeats strength and weakness in all planes according to the walking mechanism, so-called,
A comfortable contact feeling of total contact can be obtained, and blood circulation in the foot can be improved.

The rear half insole for shoes of the present invention may be inserted into a completed shoe and made removable by a hook-and-loop fastener or the like, or may be adhered with an adhesive.

Further, the fishing type of the present invention can be used for manufacturing a shoe using the insole for shoes of the present invention, and the fishing operation of the upper can be performed accurately as designed.
