DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shin protector worn for the purpose of protecting the shin of an athlete in a game such as a soccer game, and particularly to a shin protector having antibacterial properties.

[0002]

2. Description of the Related Art A conventional shin protector (P2) is fixed directly to the shin with a band fastener or the like, or inserted into a sock (S) as shown in FIG. When used repeatedly, various germs and fungi may propagate due to sweat and rainwater of the competitor.

[0003] Therefore, the shin protector in such a state.
If you continue to use (P2) as it is, itching and skin irritation may occur.
It became necessary to maintain the cleanliness of the shin protector (P2).

In view of such circumstances, for example, as disclosed in Japanese Patent No. 2810864, in a protector for protecting the shin by applying it to the shin of an athlete, the protector is made of resin (hard). An antibacterial shin protector (hereinafter referred to as prior art) formed of a synthetic resin, a sponge, or the like, and mixed by kneading or applying an antibacterial agent into the resin.
Are known, and a certain antibacterial effect is obtained by the invention.

[0005]

In general, having the antibacterial shin protector according to the prior art has antibacterial properties, that is, it is to suppress the growth of bacteria, and the effect is to prevent the growth of bacteria. Since it can only be suppressed, it is not possible to cope with the case where bacteria and the like proliferate from the dirt on the shin protector. In such a case, the shin which is the contact surface of the shin protector It is desirable to clean or wash with a detergent after use, even if it is a synthetic resin product, since it may cause itchiness or skin irritation.

However, since the shin protector according to the prior art is formed of a sponge or a synthetic resin plate, when the shin protector is washed by a washing machine, particularly, the sponge portion of the shin protector is
It is not preferable because abrasion and cracks occur due to contact with other laundry in the washing tub and collision with the inner wall of the washing tub,
In addition, even when the shin protector is hand-washed with a detergent, the surface of the shin protector is strongly rubbed, so that wear and cracks are likely to occur.

Further, since the antibacterial shin protector according to the prior art is obtained by kneading or applying an antibacterial agent to a hard synthetic resin or a sponge, the antibacterial agent is eluted or peeled off by washing or the like. By doing
There is also a drawback that the durability of the antibacterial effect is easily impaired. For this reason, the antibacterial shin protector cannot be washed frequently, and as a result, even if it has antibacterial properties, it is not hygienic. There's a problem.

Further, since the sponge itself is relatively durable, regardless of whether or not it is washed,
The cushioning property of the sponge portion is easily damaged, and the durability of the entire antibacterial shin protector is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is possible to maintain the antibacterial property, not to cause abrasion at the time of washing, to keep clean, and to reduce the antibacterial property by washing. An object of the present invention is to provide an antibacterial shin protector which does not occur and has excellent cushioning properties and durability over a long period of time.

[0010]

An antibacterial fabric blended with antibacterial fibers is adhered to at least the inner surface of the thermoplastic synthetic resin or synthetic rubber non-bacterial core material which is on the shin contact side, An antibacterial shin protector characterized by having a curved shape adapted to a shin is used as means for solving the problem.

[0011]

According to the present invention, since a core material made of a thermoplastic synthetic resin having no antibacterial property is wrapped by a thermoplastic fabric mixed with antibacterial fibers, the core material is not exposed, and It does not cause wear of the core material at the time, and can have excellent durability.

In addition, since the thermoplastic fabric mixed with the antibacterial fiber is used, the antibacterial effect is always ensured by the antibacterial fiber, and the antibacterial effect is reduced by elution or peeling of the antibacterial agent due to washing or the like. Almost no
The antibacterial effect can be maintained for a long time.

Furthermore, when chitin and chitosan are used as the antibacterial fiber, since the chitin is present in the shellfish and the like from the beginning, the disposal of the antibacterial shin protector is considered to be environmentally friendly. And an antibacterial effect against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Trichophyton and the like can be obtained.

[0014] Further, by providing a ventilation path forming portion by embossing on the inner surface of the antibacterial shin protector, the flexibility of the antibacterial shin protector is further improved, and the shin is fitted exactly along the shin portion. In addition, since it is possible to ensure the protection of the skin and to secure a sufficient air permeability, the generation of sweat is suppressed, and the clean feeling is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of an antibacterial shin protector (P) according to an embodiment of the present invention, and FIG.
3 is a rear view of the antibacterial shin protector (P) according to the embodiment, and FIG. 4 is a rear view of the antibacterial shin protector (P) according to the second embodiment of the present invention. FIG.

As shown in FIGS. 1 to 3, the antibacterial shin protector (P) according to the first embodiment of the present invention is curved to have a length of about 180 mm and a width of about 90 mm so as to fit the shin. As a core material without antibacterial effect (1), it covers a relatively hard sponge-like foamed polyethylene plate as a whole,
A cloth made of thermoplastic synthetic resin in which chitin and chitosan are blended as antibacterial fibers (hereinafter referred to as antibacterial cloth (2)) is closely adhered. The ventilation projections (4
a) is configured such that decorations are provided on the outer surface side.

Here, the method of manufacturing the antibacterial shin protector (P) according to the first embodiment is as follows: a flat-plated foamed polyethylene core material (1) is used, and two antibacterial cloths (2) are used. That is, it is performed by sandwiching the outer-side antibacterial fabric (2a) and the inner-side antibacterial fabric (2b), and hot-press molding the antibacterial fabric (2) together.

[0018] By this press molding, a curved shape adapted to the shin portion (F) is obtained, and an antibacterial shin protector is provided.
On the outer surface side of (P), the decorative portion (3) is formed, and on the inner surface side, a ventilation convex portion (4a) is formed as a lattice-shaped ventilation path forming portion (4),
Furthermore, the edge portions of the two antimicrobial fabrics (2) and the core material and the two antimicrobial fabrics (2) are adhered to each other by heat welding, and the core material (1) is attached to the two antimicrobial fabrics. The configuration shall be covered by (2).

Here, the antibacterial fabric (2) according to the first embodiment
As for, I use the clamion of Ohmi Kenshi Co., Ltd.

The antibacterial shin protector (P) according to the first embodiment has a construction in which foamed polyethylene is wrapped by an antibacterial cloth (2), as shown in FIGS. On its inner surface, a lattice-shaped ventilation convex part (4a) is provided as a ventilation path forming part (4), and the long lines constituting the lattice are bulky and the short lines are slightly low, so it is worn. Sometimes the longitudinal line abuts the shin (F),
The short line will not come into contact with the shin (F), and a ventilation hole is formed between each longitudinal line and the shin (F) so that it has sufficient air permeability, and By wearing the protector, the shin (F) is hardly stuffy,
Due to the synergistic effect of using the antibacterial material, an excellent effect of preventing the propagation of various germs can be exhibited.

Further, by providing the lattice-shaped ventilation path forming portion (4), when the antibacterial shin protector (P) presses the shin portion (F) by an external pressure, the short line is also formed. Shin
Since it comes into contact with (F), not only the breathability at the time of wearing, but also the strength of the antibacterial shin protector when an impact is applied can be sufficiently maintained.

On the other hand, in the first embodiment, the core material (1)
Is completely encapsulated by the antibacterial fabric (2), so that the antibacterial agent is kneaded or applied to the core material (1) which is shielded from the outside by the antibacterial fabric (2). It is not necessary to knead the material, and rather, by eliminating kneading and coating, the raw material and manufacturing cost of the core material (1) itself can be reduced.

Next, the second embodiment of the present invention is substantially the same in structure as the first embodiment. As shown in FIG. 4, the inner surface of the antibacterial fabric (2) has a ventilation path forming portion (4). ) Is different only in that a ventilation recess (4b) is formed. In the antibacterial shin protector according to the second embodiment, the ventilation recess (4b) extends in the longitudinal direction of the antibacterial shin protector (P). Obviously, it can be bent from the ventilation recess (4b) according to the shape of the shin (F).
It is even better in that it closely follows the shape of (F) and ensures protection of the shin (F).

Although not shown, the third embodiment of the present invention will be described.
The antibacterial shin protector (P) uses antibacterial cloth (2) only for the inner surface, and the other part of the cloth surrounding the core material (1) is non-antibacterial cloth In other words, instead of the outer antibacterial cloth (2a) in Examples 1 and 2, a non-antibacterial cloth is used, and the core material (1) is held together with the inner antibacterial cloth (2b). It can be said that it was composed.

Also in the third embodiment, the shin of the wearer
(F) does not cause itching or inflammation, has a function as an antibacterial shin protector, has abrasion resistance, and can be used for sanitary use because it can be washed, etc. Although it is common to the first and second embodiments, in addition to this, it is possible to use a normal cloth having no antibacterial property in part, so that the cost can be further reduced as compared with the first embodiment.

The present invention is not limited to the above embodiment. The core (1) does not need to be made of polyethylene and may be made of, for example, polyurethane having high biodegradability. Or a laminated structure, for example, composed of two layers of a hard synthetic resin and a soft sponge,
Even when the synthetic rubber is used, the same function and effect as the present invention can be obtained.

Further, the ventilation path forming portion (4) is not limited to the shape and the like of the above embodiment, but the ventilation path forming portion (4).
It is intended that at least a space for ventilation can be ensured in a state in which it is in contact with the shin (F).
