Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a toe guard structure suitable for sports shoes for ball games such as volleyball, basketball, handball, tennis, badminton, and table tennis, and more particularly, to an improved structure for preventing peeling while maintaining grip. .
[0002]
[Prior art and problems]
As a toe guard for sports shoes, for example, the one shown in JP-A-2002-34608 has been proposed. This toe guard is constituted by bonding or integrally molding a reinforcing portion having a low friction coefficient at a position above the rising portion of the outsole toe portion.
[0003]
With this toe guard, when the lower part of the toe part of the outsole toe with a relatively high coefficient of friction is in contact with the ground, the kicking force of the foot can be reliably transmitted to the ground surface to maintain the grip force, and the friction When the reinforcing portion at the upper part of the rising portion of the outsole toe portion, which has a low coefficient, is in contact with the ground, the foot can be smoothly slid on the ground surface (the ground surface or the floor surface).
[0004]
However, in this case, the edge of the upper part of the raised part of the outsole toe part is always exposed to the outside, so the edge part of the upper part of the raised part may be the starting point of the peeling of the outsole toe part. There is.
[0005]
Moreover, in what is shown in Japanese Utility Model Laid-Open No. 5-65204, a hard wear-resistant rubber is integrally formed on a soft toe reinforcement piece at a position corresponding to the first phalange to the second phalange of a toe portion of a tennis shoe. Thus, the toe guard is configured.
[0006]
In this case, it is possible to improve the durability of the toe portion of the upper portion by the wear resistant rubber, but the grip performance at the position where the hard wear resistant rubber is attached is lowered.
[0007]
The present invention has been made in view of such a conventional situation, and an object of the present invention is to provide a toe guard structure for sports shoes that can maintain grip and prevent peeling.
[0008]
[Means for Solving the Problems]
Toe guard structure sports shoe according to the invention of claim 1, provided et the by extending the tip of the outsole to come in contact with a ground surface to the toe portion of the carapace portion of the shoe, winding having grip portion And a toe guard body formed of a hard material and disposed so as to cover the entire winding part at the toe part of the upper part. The toe guard body has at least one opening, and the winding portion of the outsole has an exposed portion that is exposed from the opening of the toe guard body and protrudes outward from the outer surface of the toe guard body.
[0009]
According to the first aspect of the present invention, the toe portion of the upper portion is provided with the toe guard body and the winding portion having an exposed portion exposed from the opening. And since a toe guard main body is hard, it is easier to slip than a winding part, On the other hand, since a winding part is comprised from the raw material which has grip property, grip property is relatively high.
[0010]
For this reason, when the toe guard structure is in contact with the ground during exercise, the toe guard body allows the foot to slide smoothly on the grounding surface, improving durability, and the exposed part of the hoisting part to improve the grounding surface. The grip power can be demonstrated against. In addition, the exposed part of the hoisting part protrudes outward from the outer surface of the toe guard body, so that the exposed part of the hoisting part can be easily grounded during exercise. You can alleviate the feeling of discomfort and maintain a moderate grip. In addition, in this case, the entire winding part at the tip of the outsole of the shoe is covered with the toe guard body on the toe part of the upper part, so that the winding part is peeled off from the toe part of the upper part. Can be prevented.
[0011]
In the invention of claim 2, the toe guard main body and the winding part have an inner side arrangement portion extending from the tip of the toe part of the upper part to the inner side along the outer periphery of the toe part.
[0012]
In this case, it is possible to provide a toe guard structure suitable for a competition such as badminton, which is frequently used in the inner side portion of the toe portion of the upper portion.
[0013]
In the invention of claim 3, the toe guard body and the winding part have an outer side arrangement portion extending from the tip of the toe part of the upper part to the outer side along the outer periphery of the toe part.
[0014]
In this case, if the inner side portion of the toe part of the upper part is also provided on the inner side, the grip on both the inner side and the outer side of the toe part of the upper part While being able to prevent peeling, the durability can be improved.
[0015]
As described in the invention of claim 4, the protrusion amount of the exposed portion of the winding part is preferably 0.5 to 5 mm. This is because if the protruding amount is smaller than 0.5 mm, the exposed portion easily sinks into the opening of the toe guard body due to compression deformation, and the gripping force is insufficient, while the protruding amount is 5 mm. This is because, even if the exposed part is compressed and deformed, it always comes into contact with the ground and the grip force becomes excessive, which may hinder the movement.
[0016]
In the invention of claim 5, the outer peripheral edge portion of the winding portion and the opening edge portion of the toe guard body overlap each other by at least 3 mm.
[0017]
Thereby, at the time of exercise | movement, it can prevent that the outer-periphery edge part of a winding part protrudes outside from the opening edge part of a toe guard main body, and can prevent that a winding part peels from an upper part.
[0018]
In the invention of claim 6, the toe guard body has a belt-like overhanging portion that is sandwiched between the lower edge of the upper part of the shoe and the upper surface of the midsole.
[0019]
As a result, the toe guard body can be securely attached to the toe portion of the shoe.
[0020]
In the invention of claim 7, the winding portion of the outsole includes an inner-side arrangement portion extending from the narrow portion at the tip of the outsole toward the inner side and the outer side along the outer periphery of the toe portion of the upper portion, and By having the outer side arrangement | positioning part, it is formed in the substantially T shape. The toe guard body has a belt-like projecting portion that projects from the left and right sides of the narrow portion of the hoisting portion to the inside of the shoe through the lower part of the inner shell side and the outer shell side arrangement portion. The portion is sandwiched between the lower edge of the upper part of the shoe and the upper surface of the midsole.
[0021]

For convenience of illustration, the upper part of the shoe and the outsole are shown by two-dot chain lines in FIGS. 2 and 3, and the state where the upper part is removed is shown in FIGS. Has been. Moreover, in each figure, the same code | symbol has shown the same or an equivalent part.
[0022]
As shown in FIG. 1, a sports shoe 1 includes an upper part 2, a midsole 3 disposed at a lower part thereof, an outsole 5 attached to a lower surface of the midsole 3, and a toe part of the upper part 2. And a toe guard structure 6 provided on the head.
[0023]
The midsole 3 is disposed over the entire length of the shoe, and the upper midsole 30 to which the lower portion of the upper part 2 is fixed, and the midsole 3 is disposed below the midsole 3 and is mainly fixed to the heel part of the upper midsole 30. The lower midsole 31 is comprised. Further, a corrugated plate 4 having a wave shape is sandwiched between the upper and lower midsole 30 and 31.
[0024]
As shown in FIGS. 2 and 3, the outsole 5 extends to the toe portion side of the upper portion 2, and a substantially T-shaped winding portion 50 is formed at the tip thereof. A toe guard body 60 is provided on the toe portion of the upper portion 2 so as to cover the winding portion 50. The toe guard structure 6 is configured by the winding portion 50 and the toe guard body 60.
[0025]
The toe guard body 60 has three openings 60a and 60b. The winding part 50 has exposed portions 50a and 50b exposed to the outside from the openings 60a and 60b of the toe guard body 60, respectively.
[0026]
As shown in FIG. 4, the exposed portions 50 a and 50 b of the winding part 50 are preferably slightly protruded from the outer surface of the toe guard body 60, and the protrusion amount δ is preferably 0.5 to 5 mm. Moreover, it is preferable that the overlap amount k between the outer peripheral edge of the winding part 50 and the edge of each opening 60a, 60b of the toe guard body 60 is at least 3 mm. In FIG. 4, reference numeral 35 indicates an insole provided on the upper surface of the upper midsole 30, and reference numeral 36 indicates an insole mounted on the insole 35.
[0027]
As shown in FIG. 5 and FIG. 6, the toe guard structure 6 is disposed in a substantially U shape along the outer periphery of the toe portion of the upper midsole 30, and the inner shell side disposed on the inner shell side. It has an arrangement part 6A and an outer side arrangement part 6B arranged on the outer side.
[0028]
In the inner shell side arrangement portion 6 </ b> A and the outer shell side arrangement portion 6 </ b> B, the toe guard body 60 has a protruding portion 60 c that projects in a band shape on the upper surface of the upper midsole 30. These overhanging portions 60c are sandwiched between the lower edge portion of the upper portion 2 and the upper surface of the upper midsole 30 when the shoes are assembled.
[0029]
The winding part 50 of the outsole 5 is comprised from the raw material which has grip properties, such as a rubber and a thermoplastic elastomer, for example. On the other hand, the toe guard body 60 is made of a hard material containing a thermoplastic resin such as thermoplastic polyurethane or nylon.
[0030]
In the shoe 1 having the toe guard structure 6 configured as described above, since the toe guard body 60 is hard, it is more slippery than the winding part 50, while the winding part 50 is made of a material having grip properties. Therefore, the grip performance is higher than that of the toe guard body 60.
[0031]
For this reason, when the toe guard structure 6 is in contact with the ground during exercise, the toe guard body 60 can smoothly slide the foot on the contact surface, improve the durability, and expose the exposed portion 50a of the winding portion 50. , 50b makes it possible to exert a grip force on the ground contact surface.
[0032]
In this case, the toe guard body 60 and the hoisting part 50 are respectively extended from the tip of the toe part of the upper part 2 to the inner and outer sides along the outer periphery of the toe part. In both the inner side portion and the outer side portion of the toe portion of the covered portion 2, it is possible to prevent peeling while maintaining grip properties and improve durability.
[0033]
Further, in this case, the exposed portions 50a and 50b of the winding portion 50 protrude outward from the outer surface of the toe guard body 60, and the exposed portions 50a and 50b of the winding portion 50 are easily grounded during exercise. Therefore, it is possible to alleviate the uncomfortable feeling of slipping due to the ground contact of only the toe guard body 60 and to maintain an appropriate grip feeling.
[0034]
In addition, when the protrusion amount δ of each exposed portion 50a, 50b of the winding unit 50 is set to 0.5 to 5 mm, when the protrusion amount δ is smaller than 0.5 mm, each exposed portion 50a, 50b is easily compressed and deformed. This is because the grip force is insufficient due to sinking into the openings 60a and 60b of the toe guard body 60. On the other hand, when the protrusion amount δ exceeds 5 mm, the exposed portions 50a and 50b are compressed and deformed. This is because there is a possibility that the movement may be hindered due to excessive contact with the ground and excessive grip.
[0035]
Moreover, according to this embodiment, since the winding part 50 is covered with the toe guard main body 60 on the toe part of the upper part 2, the winding part 50 is prevented from peeling off from the toe part of the upper part 2. it can. In this case, the outer peripheral edge of the winding part 50 and the edges of the openings 60a and 60b of the toe guard main body 60 overlap each other by at least 3 mm. Thus, it is possible to prevent the winding edge 50 from coming off the upper portion 2 more reliably.
[0036]
Furthermore, since the toe guard body 60 is sandwiched between the lower edge of the upper part 2 and the upper surface of the upper midsole 30 via the belt-like overhanging part 60c, the toe guard body 60 is attached to the toe part of the shoe. The toe guard body 60 can be reliably prevented from coming off the upper part 2. Further, since the toe guard body 60 is made of a hard material that is slippery, the resistance force received from the ground contact surface is small, and the toe guard body 60 is less likely to peel from the upper portion 2.
[0037]
In the above embodiment, an example is shown in which three openings are formed in the toe guard body 60, but the number of openings in the toe guard body 60 is not limited to this, and at least one opening is formed. It only has to be. Further, the shape of the opening is not limited to the rectangular shape or the triangular shape as shown in the embodiment.
[0038]
Moreover, in the said embodiment, although the toe guard main body 60 and the winding-up part 50 showed the example arrange | positioned on both the inner side and the outer side of the toe part of the upper part 2, the application of this invention is shown. However, the present invention is not limited thereto, and the toe portion of the upper portion 2 may be disposed on either the inner or outer side.
[0039]
For example, when the inner side arrangement portion is arranged only on the inner side of the toe portion of the upper portion 2, the use frequency of the inner side portion of the toe portion of the upper portion 2 is high. For example, a toe guard structure suitable for a competition such as badminton can be provided.
[0040]
【The invention's effect】
As described above, according to the present invention, the toe guard structure is composed of the hard toe guard body and the outsole winding part having an exposed portion that is exposed from the opening of the toe guard body and made of a material having gripping properties. Therefore, there is an effect that the grip property can be maintained and the peeling can be prevented.
