Abstract

(57) [Abstract] [Purpose] Lightweight and fits well on the foot to release the sweating heat inside the shoe and prevent the formation of shoe beans.
Providing athletic shoes that reduce foot fatigue and enable long-term running. [Composition] The instep cover is divided into three parts, the front instep, the middle instep, and the heel instep,
The material of the instep cover is made up of two stretchable russels that have elasticity and softness, and the tongue and waist are integrated. A mesh cloth is used for the front instep, and a nylon cloth is used for the heel instep, and urethane and tricot nylon are laminated for the back cloth. Each of these insteps is sewn with a reinforcement of the heel, a shoe pad, a side decoration, a shoelace ring, and the like, and then sewn to produce the instep of the athletic shoe. An intermediate sole and a grounded sole are attached to the instep of the athletic shoe to fit well on the instep and to produce an athletic shoe having good air permeability.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to athletic shoes suitable for jogging, marathons, etc., which have improved fit and breathability to the upper part of the foot.

[0002]

[Prior art]

 The instep of a conventional athletic shoe is generally composed of a front instep called "tip", a rear instep called "waist", which has a mouth opening, and a tongue piece covering the front opening of the rear instep. It was constructed so that the shoe laces inserted through the laces of the wings provided on both sides of the rear instep were tightened to fit the instep of the foot.

[0003] A device disclosed in Japanese Utility Model Publication No. 61-37282, in which the upper band attached to the tongue from both sides of the stepless part is tightened to enhance the fit property of the instep of the foot, the heel part The device described in Japanese Utility Model Publication No. 58-16642, in which a shoelace inserted through a band provided over the front opening of the instep is tightened, and both ends of the heel pad formed on the heel are attached to the front of the instep. The device disclosed in Japanese Utility Model Publication No. 61-40164, which is tightened at the opening, and further has a pair of tongues connected to opposite edges of the front opening of the instep, respectively. There is Japanese Utility Model Laid-Open No. 4-98706 in which the tongue piece is properly fixed to the center of the wearer's instep.

Further, recently, there have been proposed the inventions in which the instep and the tongue piece are integrated as described in Japanese Utility Model Laid-Open No. 4-107607 and Japanese Patent Laid-Open No. 5-3802.

[0005]

[Problems to be solved by the device]

 In all of the prior art publications, such as JP-B-61-37282, JP-B-58-16642, JP-B-61-40164, and JP-A-4-98706, the mouth is composed of an instep and a tongue piece. However, there is a drawback in that the foot feels uncomfortable only by partially improving the fit feeling, and the weight becomes heavy.

Further, the proposals in Japanese Utility Model Laid-Open No. 4-107607 and Japanese Patent Application Laid-Open No. 5-3802 have the effect of improving the fit property and not giving a feeling of strangeness because a material having a good cushion property is used. is there. However, the instep covering made of the material used to improve these is the inner instep, and the outside of the instep is covered by the outer instep. Since it cannot be released sufficiently, it has little effect in preventing the occurrence of shoe beans. Further, there is a drawback that it is heavy in weight. The present invention has been made to solve these drawbacks.

[0007]

[Means for solving the problem]

 In the instep of a shoe, the upper instep is used, and the upper instep is sewn on the middle instep and the instep in which the tongue and the waist are integrated by using a flexible and stretchable fabric as the material. The present invention provides athletic shoes.

[0008]

[Action]

 The athletic shoe constructed as described above fits well on the instep, does not exert excessive pressure on the instep, and is less fatigued even during exercise for a long time.

[0009]

【Example】

 The athletic shoes of the present invention were mainly developed for long-distance running in the Tri Icelon competition. Examples will be described below with reference to the drawings. FIG. 2 is a development view of the three-piece instep cover of the present invention, that is, the front instep cover (2), the middle instep cover (5), and the heel instep cover (6). The front instep cover (2) is doubled by using a mesh cloth (8) in which the polyamide thread is cross-knitted on the toe portion (7) and a mesh cloth (8) in which the same thread is obliquely knitted on the back side. Similarly, a mesh cloth (8) in which polyamide yarns are diagonally knitted is used for 9). These are used by immersing them in a reinforcing liquid and coating them to give them strength. Both mesh cloths (8) are sewn together, but the mesh-like product name “Pefmate” (manufacturer, Kanebo Co., Ltd.) is also sewn simultaneously as the back cloth.

The instep cover (5) is formed by integrating the tongue piece (3) and the lumbar portion (4), but the notch (10) is made to separate the tongue piece (3) and the blade portion (11). It is provided and configured like a separate part. The material of the inner shell (5) is two layers of stretchable russell fabric, and the urethane tongue of appropriate thickness is inserted inside the tongue (3) to give it a fit. The heel instep (6) is made of nylon fabric with the trade name "YK0455A cloth" (manufactured by Kanebo Co., Ltd.) as the front cloth, and the back cloth is a combination of urethane and tricot nylon.

[0011] Each of the above-mentioned front instep cover (2), middle instep cover (5) and heel instep cover (6) has a heel reinforcement (12), a shoe pad (13), a side decoration (14), and a shoelace loop. (15) etc. are sewn on and then sewn to produce the instep (1) of the athletic shoe. A foam of a copolymer of ethylene and vinyl acetate having a small specific gravity, which is soft and excellent in cushioning property, is provided on the upper (1) of the athletic shoe manufactured above as an intermediate sole (17) to improve the foot contact of the wearer. As the body or the grounding bottom (16), a bottom made of 1.2 polybutadiene rubber foam having good abrasion resistance and a specific gravity larger than that of the foam is attached.

[0012]

【effect】

 Since the present invention is configured as described above, it has the following effects. First of all, since the middle toe is integrated with the tongue and the waist, the shoes and feet are fitted more comfortably so that they are comfortable and comfortable. Furthermore, this part is made of two layers of stretch russell fabric, the outer surface is not covered with the outer cover, and only the side decoration that also serves as reinforcement is sewn on, so it is extremely lightweight.

Particularly, in the tri-aislon competition, after swimming, cycling and a tough competition, it is necessary to run for a long distance and a long time, and the legs are considerably fatigued and swollen. However, since the middle instep is made of a material that is flexible, stretchable, and has good ventilation, it does not have a feeling of tightening against the swelling of the foot and always fits flexibly. Furthermore, since the air permeability is good, the sweat heat inside the shoes is easily released, and it prevents the legumes of the shoes and reduces the fatigue of the feet due to running for a long time.
