Description

The present invention relates to a human body support member used for fixing and supporting a human body.

In today's life-long sport, the role of the protective clothing used for the purpose of preventing injury in advance and reducing the pain, burden on the affected area, and anxiety is very important.

For personal protective clothing, such as supporters and corsets, specially shaped parts are attached to the human body where there is pain or anxiety. In order to enhance such effects, bones, which are one of the human body support members, are often inserted and arranged in the length direction of the human body.

Bone used for clothing for protecting the human body is often made of metal or plastic, and has various shapes and stiffness according to the symptoms and living conditions of the user.

Also, if the symptoms of injury are severe, a method of forcibly fixing the affected area using a cast or the like has been taken, and recently, it is not a plaster cast but a mesh cloth that hardens when exposed to the atmosphere Is often used.

Conventional bones are often used by processing a single plate made of plastic, metal, etc., or inserted into a bag part on clothing for protecting the human body such as a supporter or corset, or directly sewn and bonded. Yes. The bone part is poorly breathable and has a high degree of discomfort such as heat and stuffiness when worn, and this is a problem that increases as the area of the bone increases. For this reason, in the case of bones that cover the entire mounting portion, those having a perforated structure are often used, but there are few places for sweat to escape and discomfort is considerably high. In the case of metal or the like, there is also a problem that the burden on the affected part is increased due to the increase in weight.

In order to control the bending resistance of the bone, it is only possible to change the material and thickness, and it is extremely difficult to give direction to the bending resistance according to the structure and movement of the human body.

In general, a vertically long bone having a relatively high bending resistance is often used, and pain or rubbing may occur at the end portion of the bone and the portion corresponding to the bone of the human body.

In addition, in the cast made of mesh cloth, the constituent yarn is thin and requires lap winding. It takes time to complete.

In view of the above circumstances, the present invention has a sufficient effect for supporting the human body, is highly breathable, can be given directionality in bending resistance , reliably protects the waist, and is easily attached and detached. An object of the present invention is to provide a human body support member.

In order to achieve the above object, the human body support member of the present invention is a mesh structure, so that a large number of mesh holes are generated and has high air permeability. The number and size of the mesh can be freely changed by the manufacturing method.

Furthermore, in order to simultaneously realize air permeability, bending resistance, human body followability, etc., the human body support member of the present invention is a mesh structure in which the thickness of the warp and weft threads is changed with the filament yarn as the main component yarn. It is characterized by being. Further, the weft thread may be spirally engaged with a plurality of the warp threads.

Extra-thick filament yarns generally have a higher elastic modulus than plastics of the same material and area. For this reason, by using this as the main constituent yarn, it is comparatively light and can provide sufficient bending resistance and moderate elasticity to fix and support the human body. By changing the thickness, cross-sectional shape, alignment, number, direction, etc. of the filament yarn, it is possible to design the bending resistance according to the degree of pain and symptoms of the user and the living situation.

By changing the warp and weft of the mesh structure, and changing the type of each thread, the direction of the bending resistance and elasticity can be given as necessary, It is possible to give flexibility to an end portion that strikes strongly. As for the end treatment, there are a method of softening by changing the type of yarn and a method of soft coating using silicon or a two-component curable resin.

Furthermore, if a multi-layered structure knit or the like is used, a thick structure with a thickness of several millimeters to several centimeters can be obtained, and different performances can be provided depending on the front and back structures. In this case, it is possible to provide an effect of absorbing force or impact applied from outside or inside the human body.

The human body support member can be molded three-dimensionally to match the waist of the human body to be worn, regardless of the shape, thereby enhancing the fit and support to the human waist . .

The human body support member can be used by molding it into the shape of each part of the human body by using a vertically long unit in units of several units, or using a single surface unit in combination with clothing for protecting the human body. is there. Moreover, it can be used independently without combining with clothing for human body protection by forming into a cylindrical shape by bonding, sewing, fabric joining processing or the like.

Body support member, when used in wound body waist portion, by keeping with a hook or the like to the joint portion of the fabric ends, removable can be performed in easy and short.

The human body support member according to the present invention has light weight, breathability, and anisotropy in accordance with the structure and operation of the human body. By combining this with clothing for protecting the lower back, symptoms and living conditions of low back pain patients It is possible to provide a lumbar support product that is highly comfortable to suit the needs of the customer.

Hereinafter, some embodiments of the present invention will be described with reference to the drawings, taking as an example a case in which a wide body support member that supports the entire waist alone is assumed in combination with a waist protection garment. .

FIG. 1 is a diagram showing an example of a fabric used for a human body support member. FIG. 1A shows an example in which a very thick monofilament yarn having a cross-sectional diameter of about 0.1 to several mm is plain woven. If the warp and weft are the same yarn and the same weave density, almost isotropic bending properties are exhibited. As shown in FIG. 1B, by changing the thickness, the number of filaments, the weave density, and the like of the warp / weft, the woven fabric has different bending properties in the warp / weft direction. It is also possible to change the thread type for each thread, and various designs are possible according to the characteristics of the human body. As shown in FIG. 1 (c), a weft thread is wound in a spiral shape so as to surround each pair of the warp threads , and one warp thread of the pair of warp threads and the other warp thread adjacent thereto pairs also of the warp, the other weft is wound spirally at the outer, also in each warp and weft yarn wound on the warp of the left and right both sides is wound spirally positioned alternating structure Is possible. FIG. 1D shows an example of a multilayer structure knit. It is also possible to use a combination of two or more of these.

FIG. 2 is a diagram illustrating an example of a human body support member. FIG. 2A shows a vertically long human body support member that is often used in garment for waist protection. Thermosetting fibers such as polyester can be heat-set, so we can use woven and curved shapes with a simple mold. Moreover, an edge part can be processed by covering with heat sealing | fusion, cloth, etc. FIG. 2B shows a human body support member molded and set in a waist shape. Compared to the vertically long shape, the posture of the human body is high, and there is little displacement when worn. FIG. 2 (c) shows a human body support member molded and set in the shape of the waist of the human body. In this case, the human body support member can be used alone without using the waist protection clothing. Similarly, molding can be performed even in accordance with the shape of an arm, leg, or the like.

FIG. 3 is a diagram showing an example in which a human body support member is incorporated in a waist protection garment. FIG. 3A shows an example in which a vertically long human body support member is incorporated. Usually, several human body support members are used. A bag-like pocket may be provided in the waist protection garment, and a human body support member may be placed therein, or directly sewn to the waist protection garment. FIG.3 (b) shows the example which incorporated the member for a human body support of a waist | hip | lumbar part shape. Like the vertically long human body support member, it is incorporated by being sewn into the waist protection clothing. However, if the waist protection clothing of the human body support member portion is cut through, further greater breathability can be secured.

FIG. 4 shows an example of the air permeability of the human body support member of the present invention compared to the case of a conventional plastic bone. It is clear that the conventional product has almost no air permeability, whereas the product of the present invention (woven fabric) has a high air permeability. Further, the air permeability can be controlled by adjusting the number and size of the meshes of the human body support member as in the fabric a or fabric b in the figure.

FIG. 5 is an example comparing the results of a three-point bending test of a conventional plastic bone having substantially the same thickness and a woven fabric according to the present invention with respect to the bending characteristics of the human body support member of the present invention. Although the bending characteristics vary depending on the material and structure of the plastic or woven fabric, the product of the present invention can achieve the same or higher performance as the conventional product as a function to support the human body. By using a thick thread or by using several layers, it is possible to further strengthen the power to support the human body compared to conventional products. Further, as can be seen from the figure, it is possible to provide a single body support member with a high bending strength in the vertical direction and a weak strength distribution in the lateral direction due to the woven structure.

FIG. 6 shows an example of moisture in clothes when a subject is wearing a conventional plastic bone or a waist supporter using the human body support member of the present invention. In the case of the conventional product, the humidity in the clothes increases to nearly 100% due to exercise, whereas in the case of the present invention, the increase in the humidity in the clothes is suppressed to 80% or less. Therefore, by using the human body support member of the present invention, it is possible to improve the breathability of the supporter than before and to reduce discomfort due to heat and stuffiness.
