Japanese Patent No. 4704778

  However, in the conventional footwear, the height that the toe spring portion makes with respect to the ground (hereinafter referred to as the height of the toe spring portion) with the footwear standing upright on the ground is generally about 18 mm and high. Even less than 25mm.

  For this reason, if the user's muscular strength decreases with age or the knee bends insufficiently due to fatigue or the like, there is a probability that the toes will contact the ground (road surface) or an obstacle on the ground. As a result, it may cause a fall accident.

  According to the Ministry of Health, Labor and Welfare Workers' Injuries and Diseases Report, about 26,000 people fall a day during work and rest for more than 4 days, the most common type of occupational accident. In particular, when an elderly person falls and gets injured, the rate of getting serious is high. Among the causes of death caused by accidents in daily life, falling and falling deaths have exceeded the death from traffic accidents.

  The present invention has been developed in such a situation, and it is an object of the present invention to provide a toe-up footwear capable of suppressing the occurrence of a fall accident due to a roll.

  The invention according to claim 1 is toe-up footwear in which the height of the toe spring portion provided on the toe portion side of the shoe sole is in the range of 25 mm to 70 mm.

  According to a second aspect of the present invention, in the device according to the first aspect, the height of the toe spring portion is in the range of 25 mm to 50 mm.

  According to a third aspect of the present invention, in the device according to the first or second aspect of the present invention, the footwear is in contact with the ground with the footwear standing on the ground between the heel portion and the toe spring portion of the shoe sole. A shock absorbing material is built in the bottom of the shoe sole grounding part.

  According to a fourth aspect of the present invention, in the device according to any one of the first to third aspects, a toe-up display portion is provided on the toe portion.

  The device according to claim 5 is the device according to any one of claims 1 to 4, wherein the footwear is boots, safety shoes, sports shoes, work shoes, leather shoes, sandals, children's shoes, nursing shoes, mountain climbing shoes, hiking.

(Claims 1 and 2)
(a) As the toe-up footwear, the height of the toe spring portion provided on the toe portion side of the shoe sole was set in the range of 25 mm to 70 mm. As a result, even if the user's muscular strength decreases due to aging or the knee bends during walking due to fatigue, etc., the toe part warps more than usual by the height of the toe spring part. Thus, the probability of contact with the ground (road surface) or an obstacle on the ground is reduced, and as a result, it is difficult to hit and the occurrence of a fall accident can be suppressed.

  (b) In the user's walking cycle, while the foot after the toe kick-out phase is floating in the air (At this time, the user does not cause the toes to step on the ground and tends to warp the toes) ), The toe spring portion having a height higher than normal naturally promotes the action of warping the toe of the user, and can smoothly enter the next motion of walking. Thereby, in the walking cycle, the operation after the heel-contacting period becomes easy, and comfortable and easy walking can be performed.

(Claim 3)
(c) By raising the toe spring part, the footwear stands upright on the ground between the heel part of the shoe sole and the toe spring part during the heel contact period in the user's walking cycle. The impact transmitted to the sole contact portion that contacts the ground may become strong. Therefore, the impact can be mitigated by incorporating the shock absorbing material in the above-mentioned shoe sole grounding portion that is expected to receive an impact during the heel contact period to the entire sole contact period.

(Claim 4)
(d) In addition to giving the recognition that this footwear is a toe-up footwear due to the appearance of the toe portion that has been warped more than usual by raising the toe spring part, a toe-up display is provided on the toe portion. This makes it possible to more reliably appeal that this footwear is a toe-up footwear.

(Claim 5)
(e) The above-mentioned toe-up footwear (a) to (d), boots, safety shoes, sports shoes, work shoes, leather shoes, sandals, children's shoes, nursing shoes, mountaineering shoes, hiking shoes, winter shoes, room shoes, Widely applicable to vulcanized shoes, walking shoes, garden shoes, garden boots, etc.

FIG. 2 is a schematic diagram showing a toe-up display unit provided on the toe-up footwear. FIG. 3 is a schematic diagram showing a product manual attached to the toe-up footwear. FIG. 4 is a schematic diagram showing a walking cycle of toe-up footwear. FIG. 5 is a schematic diagram showing a walking cycle of general footwear.

  The toe-up footwear 10 shown in FIG. 1 is an example of rain boots manufactured from materials such as rubber, PVC, EVA, PU, or waterproof boots, and has a shoe sole 20, an instep 30, and a torso 40.

  In the toe-up footwear 10, the shoe sole 20 is provided with a heel part 21 at the rear part and a toe part 22 at the front part. The shoe sole 20 includes a toe spring portion 23 that is curved upward on the toe portion 22 side.

  However, in the toe-up footwear 10, the height A of the toe spring portion 23 provided on the toe portion 22 side of the shoe sole 20 (the toe spring portion 23 in a state where the footwear 10 is erected on the ground). Is set to any value in the range of 25 mm to 70 mm. If A is less than 25 mm, the prevention of rolling according to the present invention and thus the effect of suppressing a fall accident cannot be sufficiently exhibited. If A exceeds 70 mm, the toe spring portion 23 exerts an excessive warping force on the user's toes, which makes the comfort worse. According to the experiment result of the present inventors, the preferable range of A is 25 mm or more and 50 mm or less.

  In the toe-up footwear 10, the insole of the sole contact portion 24 that contacts the drawing with the footwear 10 standing on the ground between the heel portion 21 and the toe spring portion 23 of the shoe sole 20 ( A shock absorbing material 25 is incorporated in the shoe on the side of the plate-like portion where the sole touches. Specific examples of the material of the shock absorbing material 25 include natural rubber, synthetic rubber, TPR, polyurethane, EVA, polyethylene, felt material, and the like.

  In the toe-up footwear 10, a normal cushion portion 26 can be built in the heel portion 21 of the shoe sole 20.

  The shock absorbing material 25 and the cushion portion 26 may be built in the entire shoe sole 20 or may be equipped with an insole on the entire shoe sole.

  In the toe-up footwear 10, the user's toe exerts a larger pressing force on the sole 20, which results in a higher than normal tensile pressure on the upper 30. In order to prevent the destruction of the portion of the upper 30 due to the large tensile pressure, it is also conceivable to increase the thickness of the portion of the upper 30 than usual.

  In the toe-up footwear 10, when the shoe sole 20 and the upper 30 are joined with an adhesive or by vulcanization of rubber, a larger pressing force exerted on the shoe sole 20 by the user's toe is applied to the shoe sole 20. It is also conceivable to reinforce the joint strength of the joint part by winding a thicker tape around the joint part so that the joint part of the upper 30 is not peeled off.

  In the toe-up footwear 10, the toe portion 22 of the shoe sole 20 is provided with a toe-up display portion 22M as shown in FIG. In the present embodiment, the toe up display portion 22M is composed of characters “TOE UP” (or “toe up” or the like) printed on the side surface of the toe portion 22, and this footwear normally adjusts the height of the toe spring portion 23. It is displayed that the toe-up footwear 10 is higher.

  In the toe up 10, the shoe sole 20 is colored differently from the instep 30. For example, with respect to the black upper 30, the shoe sole 20 is made yellow, and the toe spring portion 23 in the toe portion 22 colored in yellow is conspicuous that the height is higher than usual. good.

  The toe-up footwear 10 can be attached with a product description 50 as shown in FIG. 3 at the product display stage. The product description 50 has the characters “TOE UP”, “It's hard to crawl because the toe is raised!”, “Reliable”, “Comfortable walking”, etc. It explains that the footwear 10 is raised toe-up.

  FIG. 4 shows the walking cycle of the user wearing the toe-up footwear 10 “i. Heel contact period, ii. Sole sole contact period, iii. Toe kick-out period, iv. The walking cycle of the user who wears the footwear 1 is “i. Heel contact period, ii. Whole sole contact period, iii. Toe kicking period, iv. 4 and 5, when an obstacle is installed on the ground and the toe-up footwear 10 and the ordinary footwear 1 are compared, the probability that the toe-up footwear 10 is in contact with the obstacle is lower than that of the ordinary footwear 1. In addition, even when there are no obstacles on the ground, the probability that the shoe bottom touches the ground (road surface) is low, and as a result, it is recognized that the probability of a fall accident occurring is low.

Therefore, according to the present embodiment, the following operational effects can be obtained.
(a) As the toe-up footwear 10, the height of the toe spring portion 23 provided on the toe portion 22 side of the shoe sole 20 was set in the range of 25 mm to 70 mm. As a result, even if the user's muscular strength decreases due to aging, or the knee bend during walking becomes insufficient due to fatigue or the like, the toe portion 22 is larger than usual by the height of the toe spring portion 23. The probability of coming up and contacting the ground (road surface) or an obstacle on the ground is reduced, and as a result, it is difficult to hit and the occurrence of a fall accident can be suppressed.

  (b) While the foot after the toe kick-out stage is floating in the air in the user's walking cycle, the toe spring portion 23 having a height higher than usual naturally exerts an action of warping the user's toe. Can get into the next movement of walking smoothly. Thereby, in the walking cycle, the operation after the heel-contacting period becomes easy, and comfortable and easy walking can be performed.

  (c) Since the toe spring part 23 is raised, the footwear 10 stands upright on the ground between the heel part 21 and the toe spring part 23 of the shoe sole 20 during the heel contact period in the user's walking cycle. In such a state, the impact transmitted to the sole contact portion 24 that contacts the ground may become strong. Therefore, the impact can be mitigated by incorporating the shock absorber 25 in the shoe sole grounding portion 24 that is expected to receive an impact during the heel contact period to the entire sole contact period.

  (d) The appearance of the toe portion 22 that is warped more than usual by raising the toe spring portion 23 gives the recognition that the footwear is the toe-up footwear 10, and also displays the toe portion 22 on the toe portion 22. By providing the portion 22M, it is possible to more reliably appeal that the footwear is the toe-up footwear 10.

There are also the following merits when producing the toe-up footwear 10.
(1) If a “toe-up mold” is developed at the beginning of production, the manufacturing costs of materials and processes will not increase compared to ordinary footwear. Therefore, it is possible to add high added value to a product at the cost level of general footwear.
