(First embodiment)
FIG. 1 is a perspective view of a supporter S1 according to the first embodiment. FIG. 2 is a partial cross-sectional view of the supporter S1. The supporter S1 is a supporter used by being attached to a predetermined part of the body. Here, for convenience of explanation, the case where it is configured as a cylindrical supporter used for an elbow joint or a knee joint will be described. The supporter in this specification is not a narrow meaning like a cloth woven with rubber for athletes to protect their joints and local parts, but a cloth-like one for protecting the body, and restricting movement of joints And those with the function to hold and hold bones in a certain direction, and the shape for this is not only cylindrical, but also in the form of outerwear and underwear, in close contact with the body It is used as a thing including what maintains (for example, spats, a swimsuit, etc.).

  The supporter S1 has a three-layer structure in which a plurality of members 1a, 1b, and 1c are overlapped. The members 1a, 1b, and 1c are made of rectangular sheets (clothes) having substantially the same size, and the supporter S1 is connected to the members 2a, 1b, and 1c in a state where the members 1a, 1b, and 1c are overlapped. It is formed in a cylindrical shape by connecting both ends. Both ends of the supporter S1 are subjected to a process of folding the end portions inside and binding them at the binding portions 2b and 2c so that the end portions of the members 1a, 1b and 1c are not exposed on the surface of the supporter S1. The connecting portion 2a and the binding portions 2b and 2c are both stitched, but may be welded and is not limited to these. For example, the connecting portion 2a and the binding portions 2b and 2c are higher in number density than the plurality of dot-like welded portions 3, and the size of the dot-like welded portions 3 is larger than that of the plurality of dot-like welded portions 3. The supporter S3 of the present embodiment may be manufactured without using a stitching means. Each member 1a, 1b, 1c may be one sheet (fabric) or two or more fabrics stitched together.

  The members 1a and 1c constituting the outer peripheral layer and the inner peripheral layer are sheets having characteristics excellent in air permeability, water absorption, stretchability, and the like, for example, a fabric of a chemical fiber material such as nylon (fabric made of synthetic yarn) Is used. The intermediate layer member 1b is an impact absorbing material that absorbs external impact, and an elastic body such as a polyurethane sheet is used, for example. Any of the members 1a, 1b, and 1c is thermoplastic. For example, only the members 1a and 1c are made thermoplastic, only the member 1b is made thermoplastic, or any combination capable of integrally welding the members. good. The material of the supporter is a fiber such as rayon, polyester, nylon, acrylic, or the like, in which rubber fibers are woven, piled, or multi-layered. The members 1a and 1c include rayon, polyester, and the like. Further, a chemical fiber such as acrylic can be used, and as the intermediate layer member 1b, a rubber-like chemical fiber woven or piled can be used.

  The members 1a, 1b, and 1c are welded to each other by a plurality of dot-shaped welded portions 3, 3, and 3, thereby being connected to each other. That is, when manufactured using the welding means 6 to be described later, as shown in FIG. 2, the upper member 1a of the outer peripheral layer is formed with a hole and welded to the intermediate member 1b. The member 1c is formed with a hole and welded to the intermediate member 1b, and the welded portion 3 looks like a single piece. Therefore, in the sense that the three layers become one layer, the welded portion 3 is more breathable than the other portions 4. The welded portions 3, 3, are formed at intervals, and the portion 4 where the welded portion 3 is not formed is a characteristic of each member 1a, 1b, 1c (breathability, water absorption, Elasticity and the like) are maintained. Accordingly, the original characteristics of the member are effectively exhibited by the portion 4 where the welded portion 3 is not formed while the supporter having a plurality of layers can be easily manufactured by welding.

  The dot-like welded portion 3 has a substantially circular shape, but is not limited thereto, and may be a triangle, a quadrangle, or other shapes. Further, the size, the number, the formation location, and the pitch of the welded portions 3 of the welded portions 3 are also arbitrary, and may be determined as necessary. In the present embodiment, the welded portion 3 has a diameter of about 1 mm to 5 mm, a pitch between the welded portions 3 of about 10 mm to 30 mm, and a region where the members 1a, 1b, and 1c are overlapped, that is, a supporter. It is uniformly formed at predetermined intervals throughout S1. Thereby, each member 1a, 1b, 1c is connected over the whole supporter S1, and while the position shift and peeling of each member 1a, 1b, 1c are surely prevented, the portion 4 where the welded portion 3 is not formed, Functions such as air permeability as a whole of the supporter S1 are ensured.

  The supporter S1 is manufactured as follows. FIG. 3 is an explanatory diagram for explaining the manufacturing process. (1) The members 1a, 1b, 1c are overlapped. (2) The welding part 3 is formed using the welding means 6. The welds 3 may be formed sequentially, but it is efficient to form a plurality of welds 3 simultaneously using a plurality of welding means 6 arranged in a pattern so as to correspond to the welds 3. The welding means 6 may use any method as long as the member can be melted and bonded by heat, such as hot plate welding, laser welding, high frequency welding, vibration welding, and ultrasonic welding. (3) The upper and lower ends of each member 1a, 1b, and 1c in the welded state are folded inside and bound by the binding portions 2b and 2c, and end processing is performed, and the connecting portions 2a are stitched together by overlapping the left and right ends. . Thereby, it becomes a cylindrical supporter S1. In addition, the order of (1)-(3) can be changed suitably, and it is also possible to form the welding part 3 after shape | molding in a cylinder shape. Further, the connecting portion 2a and the spelling portions 2b and 2c can be replaced with stitching to perform a welding process. Thereby, it becomes possible to form the welding part 3 and the connection part 2a and the binding parts 2b and 2c by the same means and the same process, and manufacture becomes easy.

(Second Embodiment)
FIG. 4 is a perspective view of the supporter S2 including the impact absorbing member 1d. FIG. 5 is a partial cross-sectional view taken along the line AA ′ of the supporter S2. The supporter S <b> 2 is provided with an impact absorbing member only at a position corresponding to the elbow joint or knee joint, and is disposed around the hole 5 formed at a position corresponding to the joint. A shock absorbing member 1d is provided. Constituent elements common to the above embodiment are denoted by the same reference numerals and description thereof is omitted.

  A hole 5 is formed in the outer peripheral side member 1a and the inner peripheral side member 1c, and is sewn along the hole 5 at a stitching location 2d. The shock absorbing member 1d has a donut shape, and is disposed between the outer peripheral member 1a and the inner peripheral member 1c so as to surround the hole 5. A welded portion 3 is formed in a region where the shock absorbing member 1d is disposed, whereby the overlapping members 1a, 1b, and 1d are connected. The donut-shaped impact absorbing member 1d is easily attached by welding, and the laborious work of sewing along the shape is not necessary. In the region where the shock absorbing member 1d is not disposed, the outer peripheral side member 1a and the inner peripheral side member 1b are overlapped, and both the members 1a and 1b are welded at the weld portion 3. The portion 4 where the welded portion 3 is not formed maintains its characteristics, and functions such as air permeability can be secured as a whole of the supporter.

  Here, since the impact absorbing member (elastic pad) 1d receives an impact from the outside at the time of mounting, the impact absorbing member (elastic pad) 1d may be easily peeled off. Moreover, since the area | region where 1 d of shock absorption members are not arrange | positioned covers a body part widely, it is preferable that air permeability etc. are high. Therefore, in the region where the shock absorbing member 1d is disposed, it is preferable to increase the number density of the welded portions 3 as compared with other regions. Thereby, in the region where the shock absorbing member 1d is disposed, the connection strength of the members 1a, 1c, 1d is increased to prevent the shock absorbing member 1d from falling off, and the region where the shock absorbing member 1d is not disposed. Therefore, functions such as air permeability can be ensured. The impact absorbing member 1d is a member having urethane foam, silicon, rubber material or cushioning properties, and has a donut shape.

  This supporter S2 is manufactured as follows. (1) The outer peripheral side member 1a and the inner peripheral side member 1c are overlapped, the periphery of the hole 5 is stitched and turned over, and the end of the periphery of the hole 5 is folded inside. (2) The impact absorbing member 1d is disposed between the members 1a and 1b. (3) The welding portions 3a and 3b are formed by the welding means 6. This eliminates the time-consuming work of sewing in a circular shape along the impact absorbing member 1d and facilitates manufacturing. (4) The upper and lower ends of the welded members 1a and 1c are folded inside and bound by the binding portions 2b and 2c, and the left and right ends are overlapped and connected by the connecting portion 2a. Thereby, it becomes a cylindrical supporter S1. In addition, as supporter S2, it is also possible not to directly apply the welded portion 3 to the impact absorbing member 1d, but to apply the welded portion 3 so as to stop the outer periphery of the impact absorbing member 1d as shown in FIG. is there.

(Third embodiment)
FIG. 7 is a front view of the supporter S3 of the present embodiment. This supporter S3 is a knee supporter, in which a hole 5 for exposing the patella is formed, and in the outer peripheral region R1 near the hole 5, a dot-shaped weld portion 3b having a large number density and a large size is formed. In the outer peripheral region R2, dot-shaped welds 3c having a small number density and a small size are formed by the dot-shaped welds 3b. Therefore, in the vicinity of the patella, the tightening force by the dot-shaped welded portion 3b is exerted strongly. Contrary to this, in the outer peripheral region R1 near the hole 5, a dot-shaped weld portion 3a having a small number density and a small size is formed, and in the outer peripheral region R2, the dot-shaped weld portion 3a is formed. Thus, the dot-like welded portion 3b having a large number density and a large size can be formed, and the fastening force by the dot-like welded portion 3b can act weakly near the patella.

(Fourth embodiment)
FIG. 8 is a perspective view of the supporter S4 of the present embodiment. This supporter S4 is a knee supporter and has a three-layer structure in which substantially the same rectangular sheets 1a, 1b, and 1c of chemical fiber materials are overlapped, and longitudinal lines L1 and L1 are provided on the left and right. These lines L1 and L1 are configured as a plane L1 formed by solid welding, that is, a set of dot-like welded portions 3. The supporter S6 does not have the connecting portion 2a by stitching as in the first embodiment, and the both ends of the chemical fiber material sheet are connected by forming the lines L1 and L1 by solid welding. ing. The lines L1 and L1 are provided with a reinforcing member P to which a urethane pad is heat-sealed.

  The supporter S4 is for the knee and has a hole 5 for exposing the patella. Above the hole 5, the supporter S4 is formed as a line M made up of a large number of dot-shaped welds. A line M formed of a set of a large number of dot-like welds is formed on the front side of the supporter S4 between the lines L1 and L1. This is provided in order to prevent the supporter 4 from inadvertently shrinking (sagging) in the direction of arrow F in FIG. On the rear side of the supporter S4 between the lines L1 and L1, dot-like welds 3, 3, are formed at predetermined intervals. In addition, below the hole 5, the line M which consists of a group of many dot-like weld parts, and the dot-like weld parts 3, and 3 are not provided.

  According to the supporter S4, when worn on the knee, on the rear side of the supporter S4, the number density of welded portions is low, and characteristics such as air permeability, water absorption, stretchability, and sweating properties are exhibited. . In addition, at the location of the line M made up of a large number of dot-like welded portions above the hole 5, the welded portion becomes thin, and thus characteristics such as air permeability, water absorption, stretchability, and sweating properties are exhibited. 8 prevents the supporter 4 from being carelessly shrunk in the direction of the arrow F in FIG.

(Welding device for supporter)
The supporter welding device Sys of the present embodiment is for forming a welded portion of the supporter of the present invention. FIG. 9 is a conceptual diagram of the supporter welding apparatus Sys when applied to the supporter S1 of the above embodiment as an example. The welding device Sys includes a plurality of welding means 6, 6 for forming the welding part 3. The welding means 6 has a function of welding each member constituting the supporter. For example, any welding method such as hot plate welding, laser welding, high frequency welding, vibration welding, ultrasonic welding, or the like may be used. .

  The welding means 6 is arranged in a pattern at a vertical position corresponding to each welding portion 3 on each substrate 7 of the pair of substrates 7 and 7. For example, when applied to the supporter S <b> 1, they are uniformly arranged at predetermined intervals so as to correspond to the welded portions 3. Further, when applied to the supporter S <b> 2, it is arranged excluding a range corresponding to the hole 5. The arrangement density may be increased only in the portion corresponding to the donut-shaped impact absorbing member 1d. It is preferable that the welding means 6 be detachable from the substrates 7 and 7 so that the pattern can be freely changed as necessary. The arrangement patterns of the welding means 6 of the substrates 7 and 7 are the same, and the welding means 6, 6, 6 face each other when the substrates 7, 7 are brought close to each other.

  The welding means 6, 6, 6 and the substrates 7, 7 can be operated by the operating means 9. The operating means 8 controls ON / OFF of the welding operation for the welding means 6, 6, 6, adjusts an energy output amount such as a heating temperature, and operates a lifting operation for bringing the substrates 7, 7 close to each other. It has a function. Information on the operation means 8 is input to the control means 9, and the control means 9 controls the welding means 6, 6, 6 and the substrates 7, 7 to the optimum state based on the information from the operation means 8.

  This welding apparatus Sys is used as follows. First, when the welding means 6, 6 are detachable from the substrates 7, 7, the welding means 6, 6 are arranged on the substrates 7, 7 in a desired pattern. Next, the support members 1a, 1b, and 1c are arranged in a state of being overlapped between the substrates 7 and 7 on which the welding means 6 and 6 are arranged in a pattern. When the operation means 9 performs a necessary operation, the control means 9 controls the substrates 7 and 7 and the welding means 6, 6, and the substrates 7 and 7 move to positions close to each other. ,, 6 are in a state in which the heating temperature and frequency are adjusted, and the welds 6,, 6 are formed in an appropriate state.

  Since the welding means 6,..., 6 are arranged in a pattern, the welded portions 3,..., 3 can be patterned at once on each of the superposed members 1a, 1b, 1c. Even if members having various shapes are used as the members constituting the supporter, the welding means 6, 6 may be arranged according to the shape, and the welded portion 3 can be easily attached to any shape member. Can be formed. When the member to be welded is disposed only on a part of the supporter, it is easy to form a welded part only at a necessary location by adopting an arrangement pattern corresponding to only that part. By adjusting the arrangement density of the welding means 6, 6, 6, it is easy to form the welding parts so that the number density of the welding parts is different.

  As described above, according to the supporter of the present invention, functions such as air permeability, water absorption, and elasticity can be ensured while being easily manufactured by welding.

  The present invention is not limited to the embodiment described above. For example, it is not limited to those attached to the knee joint and elbow joint, but may be attached to any part such as the abdomen, upper arm, forearm, thigh, lower leg, and the like. In addition, each member constituting the supporter is not limited to the above, and for example, a member that bears tension, bending rigidity, compression force, a member having a heat retaining function, and other members depending on the purpose of the supporter. Can be used. In addition, the supporter is not limited to a structure having a plurality of layers as a whole. For example, when an impact absorbing member is disposed on a part of a single-layer supporter body, at least a part of the supporter is configured by a plurality of layers. In addition, it is only necessary that the dot-like welded portion is formed in the plurality of layers. It is also possible to form a plurality of dot-like welded portions in a pattern that matches the reinforcing member of the supporter with the reinforcing member that is used to restrict the movement of muscles and joints or to hold it under pressure. Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
