BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hallux big toe supporter having, at least in part, an elastically stretchable cylindrical cover covering a part of the human body.

Conventionally, as a supporter for the purpose of improving blood flow and correcting fingers by having an elastically expanding and contracting cylindrical cover that covers part of the calf and foot, which are parts of the human body, Patent Document 1 has been proposed. The leg/foot care supporter disclosed in and the bunion supporter disclosed in Patent Document 2 are known.

The leg/foot care supporter disclosed in Patent Document 1 can be pushed up from the ankle part of the leg to the lower part of the knee by gradually changing the wearing force and tightening force from strong to weak. Specifically, it is intended to be able to perform compression, tightening, and heat retention at the same time. The strongest compression clamping part with the strongest compression force and clamping force is formed, and the strongest compression clamping part is applied to the calf covering part other than the shin covering part between the upper part of the strongest compression clamping part and the leg insertion part. As you go from the upper part of the pressure tightening part to the below-the-knee covering part, the pressure and tightening force of the strongest pressure tightening part become smaller, and the pressure and tightening force gradually decrease in stages, and from the entire circumference of the lower leg pressure tightening part A gradually decreasing weak pressure fastening portion is formed by knitting a plurality of weak pressure fastening portions that are short and mainly press and fasten the crotch portion at predetermined intervals.

In addition, the supporter for hallux valgus disclosed in Patent Document 2 does not easily lose its correcting power over time, and the user feels uncomfortable when wearing shoes or walking, and blisters occur. It is intended to be less intimidating and less conspicuous even when worn under thin stockings. A supporter body made of elastic mesh fabric, and a cylindrical thumb extending from the big toe side of the supporter body and hooked on the tip of the big toe (big toe) and made of the same mesh fabric as that of the supporter body. The hook part is integrally formed, and a peripheral edge reinforcing elastic material having stretchability and finer mesh than the mesh fabric is thermally welded to the peripheral edge part on the back side of the supporter body and the thumb hook part.

As shown in FIGS. 1 and 4, the supporter 1t for hallux valgus includes a tubular cover 2 to be attached to the tip side of the foot Hpf, which is a part Hp of the human body H, and the tip of the tubular cover 2 A pocket-shaped thumb attachment part 11 to be attached to the thumb Hft of the foot Hpf is integrally provided. As a result, it can be worn and used on the tip end side of the foot Hpf in the same manner as socks. The tubular covering part 2 and the thumb attaching part 11 are elastically stretchable sewn from one or more fiber materials of chemical fibers such as polyurethane, polyester, nylon and acrylic, and natural fibers such as silk and cotton. be. Therefore, it may be manufactured as a dedicated cylindrical covering part 2 and a thumb mounting part 11 for the hallux valgus supporter 1t according to the present embodiment, or may be used by processing general socks on the market. is also possible. 2f and 2m denote sewn mouth rubber portions provided at the tip and intermediate portions of the open cylindrical covering portion 2 to prevent misalignment.

On the other hand, on the surface of the cylindrical covering portion 2, an elastic adhesive material 3 made of rubber or elastic resin material, preferably silicon rubber material 3s, is applied to obtain a pressure as shown in FIGS. A pattern portion 4 is provided. 2 and 3 show a state in which the tubular covering portion 2 (a hallux valgus supporter 1t) is flattened (crushed), FIG. 2 showing the left side (thumb side), and FIG. 3 showing the right side. (little finger side). Therefore, the right side portion of the pressure pattern portion 4 appearing in FIG. 3 and the left side portion of the pressure pattern portion 4 appearing in FIG. 2 form a single continuous pattern.

The pressure pattern portion 4 basically varies the application density R of the elastic adhesive material 3 in stages corresponding to different application areas Xa, Xbp, Xbq, . . . By making the application areas Xa, Xbp, Xbq, . . . In this case, according to the magnitude of the contact force Fm, there are four types of contact pressure portions, that is, the strong pressure contact portion 4a having the highest contact pressure Fm, the middle upper contact pressure portion 4b having the second highest contact pressure Fm, It has a middle underwear pressure section 4c with the third largest pressure Fm and a weak pressure section 4d with the fourth largest pressure Fm, and a predetermined pressure Fm is set in the range of approximately 10 to 35 [hPa]. can do. As a result, it is possible to apply five stages of wearing pressures Fm to the part of the human body H to which it is worn, including the wearing pressure Fm of the cylindrical cover 2 itself.

Further, as shown in FIGS. 2 and 3, the shape of the pressure pattern portion 4 is such that an application area Xa is arranged on the side surface of the cylindrical cover portion 2 on the side where the thumb attachment portion 11 is provided, and this application area Xa , coating areas Xbp and Xbq, coating areas Xcp and Xcq, and coating areas Xdp and Xdq are sequentially arranged on both sides in the circumferential direction. As a result, the overall shape of the pressure pattern portion 4 becomes an elongated strip, with the application areas Xbp, Xcp, and Xdp positioned on the upper side and the application areas Xbq, Xcq, and Xdq positioned on the lower side. In addition, each application area Xdp and Xdq is positioned near the little finger Hfs as shown in FIG. Further, the application areas Xcp and Xcq are formed in an elongated shape, and one end side is positioned near the application area Xa and on the front end side, and the other end side is positioned near the little finger Hfs and on the rear end side. Let Coating areas Xbp and Xbq are arranged between the coating areas Xa and Xcp and between the coating areas Xa and Xcq, respectively. , Xdq respectively.

In this case, the application area Xa is formed in the high pressure portion 4a, the application areas Xbp and Xbq are formed in the middle and upper pressure portion 4b, the application areas Xcp and Xcq are formed in the inner and upper pressure portion 4c, and the application area Xdp. , Xdq are formed in the weak pressure portion 4d. Note that the mutual boundary portions of the application areas Xa, Xbp, Xbq, Xcp, Xcq, Xdp, and Xdq are continuous.

On the other hand, when forming the pressure pattern portion 4, the strong pressure portion 4a is coated by so-called solid coating, and the middle upper pressure portion 4b, the middle underwear pressure portion 4c, and the weak pressure portion 4d are at least A part of it is formed by a mesh M. In this way, if at least a part of the mesh M is formed, even if the elastic adhesive material 3 is formed by coating, it can act on the human body H, unlike other methods such as making the layer thickness different. Since the magnitude and direction of the wearing force Fm can be easily changed in a wide range, it is possible to accurately perform finer adjustments including feeling of use.

Moreover, as shown in FIG. 1(b), the meshes M are formed in honeycomb shapes Mh. If formed with such a honeycomb shape Mh, in addition to the basic effect as a mesh, it is possible to apply an accurate and stable contact pressure Fm in three-dimensional directions (X direction, Y direction and Z direction). can.

Furthermore, when varying the application density R of the elastic adhesive material 3 in each of the application areas Xbp, Xbq, Xcp, Xcq, . . . , as shown in FIG. And the meshes M constituting the weak pressure part 4d are formed to have the same shape and the same size, and the selected parts are not meshed, that is, the solid coating parts Mn . to be different.

Specifically, as shown in FIG. 1(b), the weak pressure portion 4d is formed only by a honeycomb shape Mh, while the inner layer pressure portion 4c is formed by a honeycomb shape Mh, which is a solid coating portion Mn. are arranged sparsely, and the middle and upper pressure-bonding portions 4b are formed so that the number of honeycomb shapes Mh, which are the solid coating portions Mn, are densely arranged. Therefore, even if the coating density R is different, the layer thickness of the pressure pattern portion 4 can be made constant, so that flatness can be secured over the entire region of the pressure pattern portion 4 and the target pressure force Fm can be easily set. be able to. Moreover, even when the pressure pattern portion 4 is provided on the back surface of the tubular covering portion 2, it is possible to avoid the problem of significantly degrading the usability.

When the elastic adhesive material 3 (silicon rubber material 3s) is applied to the surface of the cylindrical covering portion 2, it can be applied using a curved surface printing screen printer.

Specifically, the surface of the tubular covering portion 2 can be printed (applied) by using a curved surface printing screen printer that prints on a cylindrical curved surface as the screen printer.

Further, the pressure pattern portion 4 is formed on the printing screen, and the silicon rubber material 3s is accommodated on the printing screen. By rotating the cylindrical platen and moving the printing screen in synchronism with the rotation, the silicon rubber material 3s on the printing screen is imprinted by the squeegee brought into contact with the printing screen. As shown in 4, a pressure pattern 4 can be formed (applied) on the surface of the cylindrical cover 2 by the silicon rubber material 3s. Therefore, the thickness (layer thickness) of the obtained pressure pattern portion 4 is constant at any portion.

After the printing is finished, the cylindrical covering portion 2 is dried while being attached to the cylindrical platen. Thus, when the silicon rubber material 3s is hardened, the desired supporter 1t can be obtained by removing the cylindrical covering portion 2 from the cylindrical platen. The drying treatment may be natural drying treatment or forced drying treatment by heating. Moreover, a stepwise drying process that combines natural drying and forced drying may be used.

The hallux valgus supporter 1t is attached to the tip side of the foot Hpf as shown in FIG. FIG. 5 graphically shows the magnitude of the contact force Fm by the size of the black circles. In this case, in the pressure pattern portion 4, the strong pressure portion 4a is positioned on the side surface of the thumb Hft side, and both the upper surface side and the lower surface side of the pressure pattern portion 4 gradually decrease as the pressure Fm goes toward the little finger Hfs side. , the contact force Fm is distributed like a triangle indicated by the imaginary line Kf in FIG. works.

Further, as shown in FIG. 6, at the front-rear direction position Pp on the side surface of the thumb Hft side, a relatively maximum contact force Fqm in the front-rear direction acts on the thumb Hft side, and on the little finger Hfs side. At a position Pq that is offset backward by a width Lr from the position Pp on the side surface, a relatively maximum contact pressure Fpm in the front-rear direction acts on the little finger Hfs side.

As a result, the pressure pattern portion 4 presses the position near the metatarsophalangeal joint, and as a result, the thumb Hft is corrected in the opposite direction, that is, in the direction of the arrow De away from the second toe. be. That is, it is possible to effectively prevent (or improve) bunions.

As described above, the supporter 1t for hallux valgus according to the present embodiment is formed by applying the elastic adhesive material 3 (silicon rubber material 3s) to the surface of the cylindrical covering part 2 as a basic configuration, and the elastic adhesive material 3 are set for the entire area to be coated, and the application areas Xa, Xbp, Xbq, . . . When forming the pressure pattern portion 4 having a predetermined distribution pattern related to the magnitude of the pressure Fm applied to the part of the human body H corresponding to 2, and a thumb attachment portion 11 to be attached to the thumb Hft of the foot Hpf is integrally provided at the tip of the tubular covering portion 2, and the side surface of the tubular covering portion 2 on the side where the thumb attachment portion 11 is provided is the closest. An application area Xa having a large application pressure Fm is formed, and application areas Xbp, Xbq, . Manufacture is easy because the pressure pattern portion 4 formed so that a vector that is applied to the side of the little finger Hfs in the left-right direction (direction Dq) and pulled backward (direction Dr) acts at the same time is provided to the vicinity of the little finger Hfs. As a result, it is possible to contribute to cost reduction, and it is possible to easily set the contact pressure and the contact direction. Moreover, the setting can be performed in a wider range, and the setting can be performed flexibly and accurately. In addition, it is possible to eliminate unnecessary tightening feeling and improve wearability. In particular, the supporter 1t for hallux valgus is provided with a tubular covering portion 2 to be worn on the tip side of the foot Hpf, and a thumb attachment portion 11 to be worn on the big toe Hft of the foot Hpf is integrated at the tip of the tubular covering portion 2. As a result, a precise wearing force Fm can be applied to the thumb Hft and its periphery, which can effectively contribute to the prevention or improvement of hallux valgus.
