Abstract

PROBLEM TO BE SOLVED: To provide a supporter formed thin by continuous knitted fabric which ensures a wearing form inconspicuous from the outside of a garment and also which can restrict movement of a waist and properly support a lumbar vertebra while realizing a simple structure.SOLUTION: In a supporter, a plurality of supporting members 14-19 having low stretchability which is arranged in a band-shaped main body part 10 and a plurality of stretchable sections 10c and 10d surrounded by end edges 10a and 10b at both ends in the short direction of the main body part 10 are generated in a back part 11. The stretchable section 10c near one end edge 10a and the stretchable section 10d near the other end edge 10b are arranged differently. By making the stretching degree between up and down of the back part 11 in a worn state of the supporter different based on the arrangement state of each stretchable section, a stretching state of the back part 11 can be followed to a back shape of a waist. Thus, a backbend of a waist can be restricted and a load to a waist can be reduced by making the back part 11 abut properly to the back side of a wearer's waist.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a supporter (a support belt or a support sleeve) to be worn on a human body, and in particular, has a belt-like structure to tighten the waist, increase the pressure of the abdominal cavity and suppress the back bending movement of the waist. The present invention relates to a waist supporter that reduces the burden on the waist when moving.

  Supporters that are attached to a joint in the human body (upper and lower limbs and torso) and a predetermined range in the vicinity thereof to hold and protect the attachment site and reduce the burden during activities have been widely used.

  In particular, supporters that have a belt-like structure and tighten the lumbar region by applying pressure increase the pressure in the abdominal cavity to hold and protect the lumbar vertebrae, as well as excessive backward bending and rotation movements that lead to pain. By restricting, when the waist is moved by the wearer's daily movement or movement related to sports, the burden on the waist is reduced and the occurrence of pain is suppressed, and various types have been proposed . Examples of such conventional lumbar supporters are disclosed in Japanese Patent Application Laid-Open Nos. 2000-271159 and 2009-240738.

  Supporters for the lumbar region having a conventional belt-like structure have a configuration as shown in the above-mentioned patent document, and have flexibility that can be wound around the waist as a whole. In order to ensure a certain rigidity that can limit the movement of the lumbar spine and appropriately support the lumbar vertebrae, predetermined rigid members (posts, stays) have been provided.

Conventional supporters for the lumbar region have a problem that providing such a rigid member complicates the structure, and that it is inevitable that the wearer feels uncomfortable with the rigid member.
In addition, if the strength of the rigid member is too high, which places importance on rigidity, it will be difficult to bring these supporters into close contact with the back of the wearer's waist, and the supporters will not be able to bend from the back of the waist that is bent rather than the flat shape of the wearer. There was a problem that floating occurred and the wearer's lumbar spine could not be sufficiently supported.

  On the other hand, a conventional supporter has been proposed in which an auxiliary band is provided in addition to the belt-like main body portion to enhance the tightening force so as to ensure the effect of suppressing the backward bending without using a rigid member. However, since these structures are further complicated and cannot be formed thinly, in addition to adversely affecting the appearance of clothes (outer) worn on the outside during wearing, it is troublesome to put on and take off and cannot be used easily. Had.

  The present invention has been made to solve the above-mentioned problems, and is formed thinly with a continuous knitted fabric, ensuring a wearable form that is not conspicuous from the outside of the garment, and realizing a simple structure while closely contacting the waist. It is an object of the present invention to provide a supporter that can restrict the movement of the lumbar region and can appropriately support the lumbar spine.

Larger, anisotropic stretchable main body, and the one end that is disposed on the front surface and the back surface of the other end of the main body in the longitudinal direction, and overlaps when wound around the waist And the other end of the main body, and the main body is integrated with the main body as an arrangement that crosses between one end edge and the other end of the main body that are continuous at both ends in the lateral direction. And a plurality of substantially linear support portions having a stretchability smaller than the stretchability in the longitudinal direction in the main body portion, and the intermediate predetermined range portion in the longitudinal direction in the main body portion is a back surface of the wearer's waist Back to abut The support portion is disposed over a predetermined range on both sides of the longitudinal center position of the back portion, and includes a plurality of sets of two support portions that are symmetrically arranged across the center position. Each of the support portions formed intersects with one or a plurality of support portions forming another set, while the back portion is surrounded by the one and the other end edge portions, the support portions, and the support portions. A plurality of rectangular expansion / contraction sections are formed, and each of the expansion / contraction sections positioned near one end edge portion of the back and each of the expansion / contraction sections positioned close to the other end edge portion has at least the number and size of the expansion / contraction sections. They are arranged to make one different.

  As described above, according to the present invention, among a plurality of support portions with small stretchability disposed on the belt-like main body portion, the support portions are disposed over a predetermined range on both sides of the center portion of the back portion in the longitudinal direction of the main body portion and overlap the back portion. Are arranged so as to include a plurality of sets of two support portions that are symmetrically arranged with respect to the center position of the back portion, and a plurality of expansion / contraction sections surrounded by the respective edge portions and the support portions at both ends in the short side direction are arranged on the back portion. The support portion and the stretchable section are made to have different stretchability, and the support portions that intersect each other include a stretchable section near one end edge and a stretchable section near the other end edge. Different three-dimensional shapes on the back side of the lumbar region by varying the degree of expansion and contraction in each part of the back part with the supporter wearing state, depending on the arrangement state of each expansion and contraction section on the back part. In response to the back The expansion state caused to follow the waist back shape, back to properly abut against the waist back side of the wearer can be suppressed bending after lumbar lumbar can be reduced reliably supported by the lumbar burden.

  In addition, each support part that has flexibility and can take a shape along the back of the waist by slightly expanding and contracting can be in close contact with the back of the waist with the expansion and contraction of each expansion and contraction section. Each support part, which is continuously arranged so as to cross the body part diagonally beyond, restrains the back part of the waist together with the back part, so that the state of restricting the lateral movement of the waist part is obtained, and unnecessary movement of the waist part is obtained Can suppress the occurrence of pain due to excessive twisting of the waist.

  In addition, the supporter has a thin belt shape including the support part, so that the cost can be reduced as a simple structure while ensuring the protection performance of the wearer's waist, and it is thin and attached under clothing. Even if it is, it is not conspicuous and can be worn without giving the appearance a sense of incongruity.

  Further, in the supporter according to the present invention, if necessary, the support portion may be a pair of the two support portions that are symmetrically arranged with respect to the center position of the back portion, and may be close to the one end edge portion at the center position. A pair of two support portions that intersect at a first predetermined location, and a pair of two support portions that intersect at a second predetermined location that is closer to the other end edge at the center position. It will be.

  As described above, according to the present invention, the support part that is arranged so as to overlap the back part of the main body part and forms a symmetrical arrangement, the set of two support parts that intersect at the first predetermined position at the center position of the back part, A pair of two support portions intersecting at a second predetermined position at the center position, and arranging the plurality of expansion / contraction sections symmetrically with respect to the center position of the back portion, and arranging the one end edge By making them different from each other near the edge and the other edge, the degree of expansion / contraction differs between the upper part and the lower part of the back part based on the arrangement of these expansion / contraction sections, while the center position of the back part in the longitudinal direction of the main body part The degree of expansion and contraction can be obtained symmetrically across the back, and the back part can be evenly abutted against the back of the lumbar part in the left and right direction, supporting the lumbar spine in a balanced manner, and the burden on the lumbar part can be reliably suppressed. . In addition, the support part that forms a symmetrical arrangement that intersects at the center position of the back part is in close contact with the back of the waist part evenly on the left and right sides, restricting the lateral movement of the waist part in a balanced manner, and unnecessary movement of the waist part in the left and right direction Can be suppressed efficiently.

  Further, according to need, the supporter according to the present invention may include, in the two support portions that intersect at the first predetermined location, a location where each of the support portions and the one edge portion intersect, and the second predetermined location. In the two support portions intersecting at the locations, the locations where the respective support portions intersect with the other end edge portion are respectively located at predetermined portions that contact the back of the waist of the wearer of the main body portion, the first Each of the support portions and the one of the two support portions intersecting each other at the predetermined portion, each of the support portions intersecting the other end edge portion, and each of the two support portions intersecting at the second predetermined portion. At least one of the portions intersecting with the end edge portion of the main body portion is located at a predetermined portion that comes into contact with the waist side surface of the wearer of the main body portion.

  As described above, according to the present invention, among the portions where the support portions arranged so as to cross the main body portion obliquely and intersect at the center of the back portion in the longitudinal direction of the main body portion intersect with the end edge portions, By setting the part where the edge part away from the part and the support part intersect to the part that contacts the waist side surface of the wearer in the main body part, the support part in which the elongation is suppressed is one of the side parts of the waist part. The lumbar part will be restrained in a wide range from the predetermined part of the edge part to the other edge part beyond the center position of the main body part, and from the support part closely contacting the lumbar part to the cross arrangement taping around the lumbar part The waist can be held while maximizing the corresponding tightening effect, and unnecessary movement related to the rotation of the waist can be suppressed to further reduce the burden on the waist.

  In addition, the supporter according to the present invention, if necessary, of the two support portions intersecting at the first predetermined location, the longitudinal direction of the main body between the two locations where the support portions and the one edge portion intersect The two support portions that intersect at the second predetermined location with respect to the interval in the second portion are arranged so that the interval in the longitudinal direction of the main body between the two portions where the respective support portions and the other end edge intersect is wider. As described above, in each of the two support portions where each support portion is disposed and intersects at the first predetermined position, the one edge portion of the one support portion intersecting with the one edge portion or the one edge portion in the vicinity of the position. The first other support part arranged in a line connecting the predetermined part of the second part and the part of the other support part intersecting with the other end edge part or the predetermined part of the other end edge part in the vicinity of the part And a place where the other end of the one support part intersects or A linear connection between a predetermined location on the other edge in the vicinity of the location and a location that intersects with the one edge on the other support portion or a predetermined location on the one edge near the location. A second other support portion is further provided, and is worn so that the first predetermined portion is above the second predetermined portion in a worn state.

  As described above, according to the present invention, the distance between the two support portions that intersect at the first predetermined location, at the one edge portion close to the first predetermined location, is two at the second predetermined location. It is assumed that the spaces between the support portions are smaller than the distance at the other end edge close to the second predetermined location, and each of the two support portions crossing at the first predetermined location intersects with one end edge portion. The first predetermined portion and one end edge close to the first predetermined portion are further provided by further arranging another support portion crossing the back portion so as to form a line connecting the portion and the portion intersecting with the other end edge portion. When the supporter is worn so that the upper side is on the upper side, the degree of expansion and contraction on the one end edge side of the back lined with the finely divided expansion and contraction sections at each small support portion is set to the one end edge side. The other edge side of the back lined with a large stretch section compared to The back side of the upper back of the waist that is continuous with the back by creating a state where one end edge side of the back that is difficult to stretch, that is, the upper part of the back, is deformed inward relative to the lower part of the back. The upper part of the back is easier to follow along the constricted part, the back is made to adhere to the back of the waist by making it correspond to the shape of the back of the waist, and the restraining force by the support part on the back is increased, so the back of the waist is unnecessary The movement can be restricted appropriately.

  In addition, the two other support parts have a large inclination with respect to the longitudinal direction of the main body part and cross the back part in a direction closer to the short side direction, and in a supporter wearing state wrapped around the waist while extending the main body part The state of restricting the back of the waist and efficiently restricting the vertical movement of the waist by placing it symmetrically at a place away from the center position of the back, with the orientation closer to the vertical direction than the other support parts As a result, unnecessary movement of the waist associated with bending and stretching of the waist can be suppressed to prevent the occurrence of pain due to excessive forward and backward bending of the waist and further reduce the burden on the waist.

  In addition, in the supporter according to the present invention, the support part is formed by one-sided or double-sided decorative stitching with respect to the main body part as necessary.

  As described above, according to the present invention, the support portion is formed by double-sided decorative stitching or the like on the main body portion of the thread, and the stretchability is reduced by integrating with the knitted fabric of the main body portion in the arrangement state on the main body portion. It is possible to produce a part with a small structure in a linear shape with a simple structure, and to closely adhere to the back of the waist while appropriately restricting the back and forth of the back while wearing a supporter, and taping the waist As in the case of the case, a structure capable of restraining the waist can be obtained at a lower cost. In addition, by forming the support portion by thread stitching or the like, the support portion can be obtained without substantially increasing the thickness of the main body portion, and the user does not feel uncomfortable.

  In addition, the supporter according to the present invention is formed of a knitted fabric knitted by warp knitting continuous with the knitting direction as the longitudinal direction as necessary, and the wearer wears the supporter in a supporter wearing state. The knitted fabric that forms the main body by making the weft yarn different between the surface side knitted structure of the knitted fabric appearing on the outside and the back side knitted structure of the knitted fabric facing the wearer on the opposite side of the surface The weft yarn of the surface side knitting structure is a multifilament yarn.

  As described above, according to the present invention, the knitted fabric of the main body is formed by warp knitting, and the weft yarn having an appropriate thickness for securing the strength with the knitted fabric by warp knitting is used as a multifilament yarn, Even if the end of the fiber forming the weft appears outside the knitted fabric and hits the wearer by reducing the thickness of each fiber forming the weft while ensuring sufficient strength, it is worn As the overall supporter feels less worn, the multi-filament yarn does not appear as weft on the back side knitting structure of the knitted fabric, so that it does not adversely affect the touch of the supporter in contact with the waist. Can be improved.

  In addition, even if the warp of the knitted fabric and the weft of the back side knitted structure are thinned or the number of yarns is reduced, the strength of the knitted fabric can be maintained by ensuring the strength of the main part of the weft as a multifilament yarn. As a whole, the knitted fabric can be thinned, and the conspicuousness when worn is also improved.

Hereinafter, a supporter according to an embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, the supporter 1 according to the present embodiment includes a main body 10 formed of a stretchable knitted fabric that is continuous in a band shape, and a front surface at one end in the longitudinal direction of the main body 10 and a back surface at the other end. A hook-and-loop fastener 20 serving as the engaging portion, and a plurality of substantially linear support portions 14 having a stretchability smaller than the stretchability of the main body portion 10 and disposed integrally with the main body portion 10; 15, 16, 17, 18, 19.

  The main body 10 is formed of a knitted fabric that is continuous in a band shape, and has an anisotropic stretch property in which the stretchability in the longitudinal direction L is significantly greater than the stretchability in the short direction T perpendicular to the longitudinal direction L. It is the composition which has.

  Specifically, the main body 10 is continuously knitted in a band shape by warp knitting so that the knitting direction is the longitudinal direction of the knitted fabric, and the stretchability in the knitting direction (warp direction) is perpendicular to this. The knitted fabric is made larger than the stretchability in the weft direction. Then, in the knitted fabric constituting the main body portion 10, the surface (outer surface) side knitted structure of the knitted fabric appearing on the outside of the wearer in the supporter wearing state, and the back surface of the knitted fabric facing the wearer on the opposite side of the surface ( The inner surface side knitting structure is knitted with different weft yarns.

  The use example of the yarn constituting the knitted fabric will be described in detail. The weft of the surface side knitted structure of the knitted fabric is, for example, a multifilament yarn obtained by bundling 10 56 dtex yarns, and two of the multifilament yarns. Are used as a set. In addition, an elastic yarn is knitted in the weft direction in combination with this weft. This elastic yarn has a structure in which two polyester yarns (for example, 84 dtex) are wound around a polyurethane yarn (for example, 1880 dtex).

  The wefts of the back side knitting structure of the knitted fabric are, for example, a pair of 167 dtex polyester yarns. Further, for example, 167 dtex polyester yarn is used as the warp yarn of the knitted fabric. As described above, a knitted fabric having excellent breathability can be obtained by using a knitted fabric structure using polyester yarn or polyurethane yarn having a smooth surface without fluff.

  By forming a knitted fabric by knitting using such a plurality of types of yarn, the elasticity in the weft direction perpendicular to the knitting direction (warp direction) is significantly reduced (for example, The elongation change rate when applying a tensile load with respect to the original dimension is less than 1%), and it is a mechanism to obtain a structure that can be appropriately applied to the wearer's body without dispersing the tightening force when worn. In addition, the warp direction of the knitted fabric is appropriately stretched, and in a state where it is used as the supporter 1, it is flexible to the wearer's waist movement (bending, warping and twisting of the body due to movement of the pelvis and spine). Yes.

  In particular, the knitted fabric has a value close to the tensile strength and the shrinkage strength in the warp direction, which is the longitudinal direction of the main body, and the stretch force (elongation) and the restoring force (shrinkage) are close to each other. It is easy to stretch and is easy to wear, and can be sufficiently tightened with a knitted fabric by an appropriate restoring force equivalent to the stretching force, and the holding force as a supporter can be increased.

  In addition, since the wefts of the surface side knitted structure in the knitted fabric forming the main body 10 can be secured as multifilament yarns, the warp yarns of the knitted fabric and the wefts of the back side knitted structure are thinner than this type of conventional knitted fabric. However, even if the number of yarns is reduced, it is possible to maintain a strong property that is difficult to bend in the weft direction of the knitted fabric, and the overall knitted fabric can be thinned.

  And the weft yarn in the knitted fabric is a multifilament yarn, while ensuring sufficient strength as a weft yarn, by reducing the thickness per fiber forming the weft yarn, the end of the fiber forming the weft yarn is temporarily knitted fabric Even if it appears outside and hits the wearer, the tip of the fiber is easily deformed, the tip does not pierce the wearer, and the irritation to the wearer can be made extremely small.

  For the knitted fabric, resin processing is applied to increase the rigidity in the weft direction (the width of the main body in the short direction) to make it more difficult to break and to strengthen the support for the wearer's wearing part when the supporter 1 is worn. It can also be done.

  Specifically, the main body 10 is manufactured by cutting a single knitted fabric knitted by warp knitting into a predetermined shape corresponding to the main body 10. By forming the knitted fabric forming the main body portion 10 by warp knitting, the knitted yarn is not easily frayed from the cut even when the knitted fabric is cut, and processing into a desired shape is easy. Further, by cutting the main body portion 10 from a single knitted fabric, a seam as in the case of combining a plurality of fabrics does not occur, and it is possible to make it difficult to lose shape and bend.

  The edges (breaks) of the main body 10 are pinched and sewed with a binder tape 30 in order to reliably prevent fraying even after expansion and contraction associated with supporter wear. The sewing of the binder tape 30 is performed so as not to suppress the stretchability of the main body 10 in the longitudinal direction L. In addition, as this binder tape, what has a degree of expansion and contraction different from that of the main body 10 is adopted, and the degree of expansion and contraction of each part of the supporter is made appropriate by adjusting the combination state of the binder tape and the main body. It can also be set as the structure adjusted.

  In addition, the edges (breaks) of the main body 10 may be frayed or decorated by edge stitching or bias edge stitching, and the edges of the main body 10 may be impregnated with a resin agent. Thus, fraying may be prevented.

  The shape of the main body 10 is axisymmetric with respect to the longitudinal center (center position c). An intermediate predetermined range portion in the longitudinal direction of the main body portion 10 forms a back portion 11 that comes into contact with the back surface of the waist 100 of the wearer. Moreover, the site | part which extends diagonally from the back part 11 on both sides of this back part 11, and reaches the both end parts of the main-body part 10 contact | abuts to the abdominal front surface from the side surface of the waist | hip | lumbar part 100 in the supporter-wearing state.

  One end edge portion 10 a and the other end edge portion 10 b are continuous to both ends in the short direction of the main body portion 10. The one end edge portion 10 a connects the main body portion 10 to the back portion of the extension portion 12. 11 is located at the upper edge of the main body 10 in an arrangement in which the direction extending from 11 is obliquely upward, and includes the upper side 11 a of the back part 11 and the upper side 12 a of the extension part 12. Conversely, the other end edge portion 10 b is located at the lower edge of the main body portion 10 in the above-described arrangement, and includes the lower side 11 b of the back portion 11 and the lower side 12 b of the extension portion 12. Even when the supporter is worn, the end portion 10a of the main body 10 is worn on the upper edge, and the other end edge portion 10b is worn on the lower edge.

The said back part 11 is made into the substantially trapezoid shape by which the upper side 11a and the lower side 11b make a substantially parallel, and is set as the magnitude | size which can support a pelvis reliably according to the magnitude | size of a wearer's pelvis.
The main body part 10 including the back part 11 includes a plurality of support parts 14 arranged so as to cross between one end edge part 10a and the other end edge part 10b at both ends of the main body part 10 in the short direction. .., 19 are integrally disposed by decorative stitching on the knitted fabric. The back part 11 is partially restricted in expansion and contraction by support parts 14,..., 19 that are arranged to pass through the back part 11.

  The extending portions 12 on both sides of the back portion 11 are arranged continuously with both side end portions of the back portion 11, and the lower side 12 b is set upward at a predetermined angle α with respect to the substantially linear portion of the lower side 11 b end portion of the back portion 11. (For example, α = 14 ° to 20 °) Inclined upward from the back portion 11 so as to be inclined.

  A continuous portion of the upper side 12a of the extending part 12 and the upper side 11a of the back part 11 in one end edge part 10a is formed to have a curved concave shape. In addition, both end portions of one end edge portion 10a, that is, the end portion of the upper side 12a of the extension portion 12 correspond to the extension direction of the lower side 12b, and the extension portion 12 tapers toward the tip end. It is set in such a direction.

  In addition, although it is set as the structure formed so that the continuous part of the upper side 11a of the back part 11 in the one edge part 10a and the upper side 12a of the extension part 12 may be made into the curved concave shape, it is not restricted to this, A continuous portion of the lower side 11b of the back part 11 and the lower side 12b of the extension part 12 in the other end edge part 10b is also formed to have a curved concave shape, and the back part 11 has a wide shape with respect to the extension part 12. It is good.

  The main body portion 10 including the back portion 11 and the extending portion 12 is symmetrical with respect to a line segment connecting the midpoint of the upper side 11a of the back portion 11 and the midpoint of the lower side 11b, which is the center position c of the back portion 11 in the longitudinal direction. It will have a line-symmetric shape as an axis. However, the main body 10 is not limited to such a symmetric shape, and may be an asymmetric shape as shown in FIG. 9, for example.

The hook-and-loop fastener 20 is disposed on the front surface at one end in the longitudinal direction of the main body 10 and the back surface at the other end, respectively, and enables the front and back surfaces to overlap each other when wound around the waist 100. Specifically, the loop surface 21 of the hook-and-loop fastener 20 is disposed on the surface side not facing the wearer at one end, and the hook surface 22 of the hook-and-loop fastener 20 is disposed on the back surface facing the wearer at the other end. It is the structure arranged.
In addition, the part where the loop surface 21 is disposed may be changed from one end to the other end, and the part where the hook surface 22 is disposed may be changed from the other end to one end.

  In addition, in this embodiment, although the structure which uses the hook_and_loop | surface fastener 20 as an engaging part is demonstrated, as long as the both ends which overlap in the winding state to the waist | hip | lumbar part 100 of the main-body part 10 can be engaged, it will be engaged. For example, a button, a dot button, a snap, a hook, a buckle, a fastener (zipper, chuck), a front hook, or a spindle stopper may be used as the engaging portion. Absent.

  When both ends of the main body 10 are engaged by the hook-and-loop fastener 20 (the loop surface 21 and the hook surface 22), which is an engaging portion, the main body 10 is in an arrangement in which the lower sides 12b are continuous at both ends. Wears and becomes a shape that spreads out in front view.

  In this way, the both ends of the main body 10 are engaged and the lower side 12b is continuous, so that the extension direction of the left and right extension parts 12 is obliquely upward from the front abdomen to the side abdomen, and the front of the extension part 12 The pressure of the abdominal cavity 105 can be efficiently increased by pushing up the abdomen from below.

The support portions 14, 15, 16, 17, 18, 19 are continuous across one end edge portion 10 a and the other end edge portion 10 b that are continuous at both ends in the short-side direction T of the main body portion 10. As an arrangement such as a straight line, a curved line, a broken line, a dotted line, or a wavy line of a waveform such as a sine wave, a rectangular wave, a triangular wave, or a sawtooth wave. A plurality of parts are integrally provided in the part 10 and have a stretchability smaller than the stretchability in the longitudinal direction of the main body part 10. Specifically, it is a structure formed as a single-sided or double-sided decorative stitching portion arranged substantially linearly by sewing a thread with poor stretchability to the main body 10.
The support portions 14,..., 19 are formed on the knitted fabric forming the main body portion 10 by, for example, one-sided or double-sided decorative stitching with a two-needle or three-needle sewing machine.

The support portions 14, 15, 16, and 17 are disposed over a predetermined range on both sides of the back center position c in the longitudinal direction of the main body portion of the back portion 11, and are symmetrically disposed with the center position c interposed therebetween. A plurality of sets (for example, a set of support portions 14 and 15 and a set of support portions 16 and 17) are included. As a set of these two support portions, a first set of two support portions (support portions 14 and 15) intersecting at a _first predetermined position p1 near the one end edge portion 10a at the center position c, and And a second set of two support portions (support portions 16 and 17) crossing at a _second predetermined position p2 near the other end edge portion at the center position c.

In the two support portions 14 and 15 forming the first set intersecting at the first predetermined location p ₁ at the center position c, the location where each of the support portions 14 and 15 intersects with one end edge portion 10a is. , Each located on the back 11. Further, the portions p ₃ and p ₄ where the support portions 14 and 15 intersect with the other end edge portion 10b are predetermined portions that contact the side of the waist portion 100 of the wearer of the main body portion 10, that is, the back portion of the main body portion 10. 11 is located outside the region. More specifically, in the supporter wearing state, the other end of the main body 10 that faces the body surface part of the predetermined position on the rear side and the dividing position when the waist circumference of the wearer is equally divided into two front and rear The edge 10b is located at a predetermined location.

On the other hand, in the two support portions 16, 17 forming the second set intersecting at a second predetermined position p ₂ of the center position c, it intersects with the respective support portions 16, 17 and the other edge portion 10b Each location is located on the back 11. Further, the portions p ₅ and p ₆ where the support portions 16 and 17 intersect with the one end edge portion 10a are predetermined portions that contact the side of the waist portion 100 of the wearer of the main body portion 10, that is, the back portion of the main body portion 10. 11 is located outside the region. More specifically, one end of the main body 10 that faces the body surface part in a predetermined range on the rear side and the division position when the wearer's waist is equally divided into the front and rear in the supporter wearing state. The edge 10a is located at a predetermined location.

  Further, although the support portion is symmetrically arranged with respect to the back portion central position c in the longitudinal direction of the main body portion in the back portion 11, it does not cross any of the center positions c and is arranged away from the center position c. Two other supports 18, 19 are also included.

Among these, the first other support portion 18 is one end that is in the vicinity of a location where one end edge portion 10a of one support portion 14 intersects in the two support portions 14 and 15 forming the first set. a predetermined portion p ₇ the edge 10a, in which are arranged linearly connecting the points p ₄ intersecting the other edge portion 10b of the other support 15.

Further, the second other support portion 19 is a predetermined portion p of one end edge portion 10a that is in the vicinity of a portion of the two support portions 14 and 15 that intersects one end edge portion 10a of the other support portion 15. _8, is intended to be arranged in a linear connecting the point p ₃ intersecting the other edge portion 10b of one of the support portions 14.

  Each of these support portions 14,... 19 causes a plurality of polygonal expansion and contraction sections 10 c surrounded by one end edge portion 10 a and each support portion 14,. A plurality of polygonal expansion / contraction sections 10d surrounded by the other edge portion 10b and each of the support portions 14,..., 19 are generated, and a plurality of portions surrounded by each of the support portions 14,. A plurality of rectangular expansion / contraction sections 10e are generated.

Incidentally, in the back 11, the distance between the first predetermined position p ₁ and the one edge portion 10a of the center position c, the center position c of the second predetermined position p ₂ and the other edge portion 10b It is made smaller than the interval. For this reason, the arrangement relationship between the two support portions 14 and 15 forming the first set and the two support portions 16 and 17 forming the second set is determined by the two support portions 14 and 15 (first set). The distance d _{1 in the} longitudinal direction of the main body between the two portions where each of the support portions 14 and 15 intersects one end edge portion 10a is two support portions 16 and 17 (second set). between two positions intersecting the 16, 17 and the other edge portion 10b, it is made narrower than the distance d ₂ in the body the longitudinal direction of.

  As a result, on one end edge portion 10a side, the stretchable sections 10c finely divided by the support portions 14,..., 19 with small intervals are arranged, and on the other end edge portion 10b side, one end 10 d of expansion-contraction sections large compared with the edge part 10a side will be in the state arranged. And each expansion-contraction division 10c located near one edge part 10a in the back part 11 becomes smaller than each expansion-contraction division 10d, 10e located near the other edge part 10b, and the size (area) of the division is smaller. It will be more difficult to stretch.

  One end edge portion 10a side of the back portion 11 that is not easily stretched, that is, the upper portion of the back portion 11 is deformed inwardly (on the body side) relative to the lower portion of the back portion 11 by receiving a force that expands when worn. Thus, the upper portion of the back portion 11 can be brought into close contact with the constricted portion of the back surface of the upper portion of the waist portion 100.

  Further, the other support portions 18 and 19 are disposed on the back portion 11, so that in a supporter wearing state, while maintaining the curved surface of the back portion 11 along the curvature of the back surface of the wearer's waist 100, The bending of the back part 11 in the hand direction T can be suppressed, and the waist part 100 of the wearer can be held by the back part 11 so that the backward bending can be efficiently suppressed.

  In the present embodiment, the support portions 14,..., 19 are arranged as decorative stitches that cross between the one end edge portion 10 a and the other end edge portion 10 b of the main body portion 10. In addition to this, it is possible to form a support part by applying a separate cloth (patent cloth) or the like for reinforcement purposes to the main body part 10 for sewing, or to form an adhesive such as a polyester, By using processing methods such as dot processing, powder processing, spider web processing or film processing, an adhesive resin made of a type of resin such as polyamide, polyurethane, polyethylene (high density, low density) or ethylene vinyl acetate, It is applied to the main body 10 and heated and pressurized by a flat press, a roller press, or the like, thereby forming a support by fixing the resin to the fabric. It can also be.

  In addition, if support part 14, ..., 19 is arrange | positioned so that the expansion | extension and contraction of the back part 11 may be suppressed so that it may be crossed in the transversal direction T of the main-body part 10, arrangement | positioning as shown in FIG. The number, position, size, and range are not limited, and the support portion can be appropriately set according to the material, shape, and size of the main body portion 10 (back portion 11).

Next, the operation of the supporter based on the above configuration and the action in the wearing state will be described.
When wearing the supporter 1, the wearer first supports both ends of the supporter 1 by hand, and places the back 11 of the supporter 1 against the back of the waist 100 of the wearer, and then the loop surface of the hook-and-loop fastener 20 on the surface side. The left hand side of the supporter 21 with 21 is moved forward, the left extension part 12 is stretched diagonally downward, wound around the waist 100 of the wearer, and held with the left hand. Subsequently, the right hand side of the supporter 1 having the hook surface 22 of the hook-and-loop fastener 20 on the back side is moved forward, and the right extension portion 12 is extended obliquely downward while being wound around the waist portion 100 of the wearer. Further, the hook surface 22 at the end of the extension 12 is engaged with the loop surface 21 on the surface of the left extension 12 held by the left hand, so that the supporter 1 is fixed around the waist. After that, if you release your hand and place the entire supporter along the surface of the body, the wear is complete.

  In the state where the supporter 1 is thus worn, as shown in FIGS. 4, 5, and 6, the back portion 11 of the main body portion 10 abuts against the back surface portion of the wearer's waist portion 100 corresponding to the lumbar vertebra 101. The portion that changes from the back portion 11 to the extending portion 12 abuts on the wearer's flank portion, and the hook-and-loop fastener 20 arrangement portion in the extending portion 12 of the main body portion 10 abuts the wearer's front abdominal portion.

  In the supporter 1 according to the present embodiment, the support portions 14,..., 19 are in a predetermined arrangement state that is symmetrical with respect to the back portion center position c in the main body portion longitudinal direction of the back portion 11. 11, one and the other end edge portions 10a and 10b and the support portions 14, ..., 19 and the polygonal expansion and contraction sections 10c surrounded by the support portions 14, ..., 19 each other, A plurality of 10d and 10e are generated. And the expansion / contraction section 10c near the one end edge 10a and the expansion / contraction sections 10d and 10e near the other end edge 10b are different in size.

  Along with this, the degree of expansion and contraction in each part of the back part 11 when a force is applied in a supporter wearing state can be made different between the upper and lower parts of the back part. In other words, the degree of expansion / contraction on the one end edge 10a side of the back portion 11 where the expansion / contraction sections 10c finely divided by the support portions 14,. It can be made smaller than the degree of expansion / contraction on the other end edge portion 10b side of the back portion 11 in which the large expansion / contraction sections 10d are arranged.

  For this reason, when a stretching force is applied in the longitudinal direction of the main body 10 with the back 11 applied to the back of the waist 100 with the supporter wearing, the other edge 10b side of the back 11, that is, the lower part of the back 11 is It extends along the lower part of the back surface of the waist 100, and is in a curved state that protrudes outward. On the other hand, the one edge part 10a side of the back part 11 which is not easily stretched, that is, the upper part of the back part 11 causes a state of being deformed inward relative to the lower part of the back part 11.

  Accordingly, the back portion 11 can follow the expansion and contraction of the back portion of the waist portion 100 such that the upper portion of the back portion 11 can be more closely attached to the waist portion of the back portion of the waist portion 100, and the back portion 11 can follow the back shape of the waist portion 100. Accordingly, the back of the lumbar part 100 can be restrained by appropriately contacting the back surface of the lumbar part 100, and the lumbar vertebra 101 can be reliably supported.

  If the stretchability in the longitudinal direction of the knitted fabric forming the supporter is uniform in the vertical direction, the knitted fabric is usually brought into close contact with the entire back surface of the waist portion 100 against the back surface of the waist portion 100 having a three-dimensional curved shape including a constricted portion. This is difficult, and the knitted fabric is made to be rich in stretchability and cannot be brought into close contact with the knitted fabric unless an extremely strong stretching force is applied. However, when closely attached in this way, the curved portion that protrudes outward, such as the lower part of the waist 100 (upper part of the buttock), which originally tends to be in close contact with the knitted fabric, has an excessive tightening force and is overtightened. It tends to be uncomfortable.

  In this embodiment, by changing the degree of expansion and contraction at the support part, without affecting the rigidity due to the difficulty of expansion and contraction in the short direction peculiar to the knitted fabric, causing the relative deformation inward to the upper part of the back, The knitted fabric can be made to correspond to the constriction at the upper part of the waist 100.

  On the other hand, the support portions 14,..., 19 that have flexibility and that can take a shape along the back surface of the waist 100 by slightly expanding and contracting are accompanied by expansion and contraction of the expansion and contraction sections 10 c, 10 d, and 10 e. In close contact with the back of the waist 100.

For example, the support portions 14 and 15 that are continuously arranged so as to cross the main body portion 10 obliquely beyond the center position c of the back portion 11 are crossed portions of the support portions 14 and 15 that form a pair (the first portion The portions p ₃ and p ₄ where the end edge portion 10 b away from the predetermined portion p ₁ ) and the support portions 14 and 15 intersect with each other are brought into contact with the side surface of the waist portion 100 of the wearer in the main body portion 10 outside the back portion 11. The edge portions 10a and the support portions which are set at the parts and are separated from the crossing portion (second predetermined position p ₂ ) between the support portions 16 and 17 which are set in the same manner and which form a pair. Since the places p ₅ and p ₆ where 16 and 17 intersect with each other are set to be portions that contact the side of the waist 100 of the wearer in the main body 10 as described above, the support portions 14, 15, 16, and 17 One end edge portion on one side of 100 side to back portion 11 The waist 100 is restrained in a wide range that reaches the other edge of the back of the waist 100 beyond the center position c.

  Accordingly, the waist part 100 is held while maximally exerting the tightening effect equivalent to the taping of the cross arrangement centered on the lumbar part from the support parts 14, 15, 16, and 17 which are not easily stretched closely contacting the waist part 100, and the waist part The state which restrict | limits the movement of the horizontal direction of 100 or an oblique direction will be obtained, the unnecessary movement which concerns on rotation of the waist part 100 will be suppressed, and the burden of the waist part 100 can be reduced further.

  Further, the two other support portions 18 and 19 cross the back surface portion 11 in a direction that has a large inclination with respect to the longitudinal direction of the main body portion and is closer to the short side direction. In the state where the supporter is wound around, it is arranged in a direction closer to the vertical direction than the other support parts, and is arranged symmetrically at a place away from the center position c. In this way, the other support parts 18 and 19 can restrain the back of the lumbar part 100 and efficiently restrict the vertical movement of the lumbar part 100 in the same way as the taping arranged in the vicinity of the lumbar part. Unnecessary movement of the lumbar part 100 related to stretching can be suppressed, and the occurrence of pain due to excessive forward and backward bending of the lumbar part 100 can be prevented.

  In addition, as shown in FIG. 1, the supporter 1 sets the position of the uppermost end of the extension part 12 above the position of the upper side 11 a of the back part 11, and the angle α formed between the lower side of the back part 11 and the lower side of the protrusion part 12. Is set to 14 ° to 20 ° so that when extending, the extended portion 12 is wound so as to be in close contact with the side surface of the waist portion 100 while being extended obliquely downward, and is engaged by the hook-and-loop fastener 20 that is the engaging portion. The supporter 1 that surrounds the waist and the abdomen in a cylindrical shape has a taper shape that has a lower peripheral length longer than the upper peripheral length and expands downward (in a front view, a shape that widens toward the left and right sides). Become.

  For this reason, the supporter 1 matches the shape of the waist 100 of the wearer, and is less likely to be displaced due to the movement of the wearer's waist. With such a supporter 1, by holding the circumference of the waist from the outside and suppressing the backward bending movement that places the greatest burden on the lumbar part 100, it is possible to maintain a correct posture, stabilize the lumbar vertebra 101, and relieve back pain.

  In the supporter 1, the stretching force of the main body portion 10 acts in the longitudinal direction, so that the front extending portion 12 that attempts to narrow the distance from the back portion 11 pushes the abdomen from below to increase the pressure of the abdominal cavity 105. The lumbar vertebra 101 supported by the abdominal muscles in the abdomen and the back muscles in the back can be supported and stabilized from the inside, and the effect of alleviating back pain can be improved.

  In addition, the body part 10 of the supporter 1 applies pressure to the iliac bone 103 from both left and right side surfaces to tighten the sacroiliac joint, thereby suppressing the swinging of the sacrum 102 that is the base of the lumbar vertebra 101 and stabilizing the sacroiliac joint. Thus, the burden on the lumbar spine 101 can be reduced.

  In addition, the main body 10 can be worn by the wearer in both the back portion 11 that comes into contact with the back of the waist portion 100 of the wearer and the extended portion 12 that comes in contact with the wearer's side abdomen to the front abdomen. It will be located below the body surface part corresponding to the rib 104. Thus, the back part 11 of the main body part 10 supports the wearer's lumbar vertebra 101, and the extension part 12 of the main body part 10 can apply pressure to the abdominal cavity 105 without being obstructed by the ribs 104. It can be raised efficiently.

  Furthermore, in the supporter 1, since the extension part 12 of the main body part 10 is located below the rib 104 in the wearer's front abdomen and does not press the rib 104, the forward bending movement of the waist part 100 is not hindered. The wearer can easily bend forward, does not interfere with daily operations, and does not press on the stomach of the wearer. Can be.

As described above, in the supporter according to the present embodiment, the back portion in the longitudinal direction of the main body portion of the back portion 11 among the support portions 14,... A set of two support portions 14 and 15 intersecting the support portions 14, 15, 16 and 17 that are arranged over a predetermined range on both sides of the center position c and overlap the back portion 11 at the first predetermined position p ₁ at the center position c. , and arranged to include a set of two support portions 16, 17 which intersect at a second predetermined position p ₂ at the central position c, the edge 10a in the short direction across, 10b and the supporting portion 14, ..., a plurality of expansion / contraction sections 10c, 10d, and 10e surrounded by 19 are formed on the back part 11, and the back part 11 is elastic with the support parts 14, ..., 19 and the expansion / contraction sections 10c, 10d, and 10e. With a different state There are at least two pairs of symmetrically arranged two support portions intersecting at the center position c of the back portion 11, and an expansion / contraction section 10c near one end edge portion 10a and an expansion / contraction section 10d near the other end edge portion 10b are provided. Differently arranged, the degree of expansion / contraction in each part of the back part 11 when the supporter is worn varies depending on the arrangement state of each expansion / contraction section in the back part 11 and thus differs depending on the top and bottom of the waist part 100 back side. Corresponding to the three-dimensional shape, the stretched state of the back 11 can be made to follow the back shape of the waist 100, and the back 11 can be appropriately brought into contact with the back of the waist 100 of the wearer to suppress the back bending of the waist 100. Can be reliably supported and the burden on the waist 100 can be reduced.

  In addition, in the supporter which concerns on this embodiment, although the extension part 12 is set as the structure extended in the diagonal direction from the back part 11 on both sides of the back part 11, it is not restricted to this but is shown in FIG.9 and FIG.10 thru | or FIG. Thus, the extension part 12 can also be configured to extend straight from the back part 11 to both sides of the back part 11. Further, even when the extending portion 12 extends obliquely from the back portion 11, the extending portion 12 is not limited to a configuration extending obliquely upward from the back portion 11, but extends as shown in FIGS. The part 12 may be configured to extend obliquely downward from the back part 11.

Further, in the supporter according to the embodiment, the distance d ₁ in the longitudinal direction of the main body between the two portions where the two support portions 14 and 15 forming the first set and the one edge portion 10a cross each other is: It has a configuration that is narrower than the distance d _{2 in the} longitudinal direction of the main body between the two portions where the two support portions 16 and 17 forming the second set intersect with the other edge portion 10b. However, as shown in FIGS. 18 to 21, the support portions may be arranged such that the distance d ₁ and the distance d ₂ are the same. However, also in this case, the size (area) of each section is smaller than each of the expansion / contraction sections 10c positioned near the upper edge portion 10a than the respective expansion / contraction sections 10d and 10e positioned near the lower end edge section 10b. Thus, it is preferable that the material does not easily expand and contract.

Further, in the supporter according to the embodiment, two support portions 14 and 15 forming the first set intersecting at a first predetermined position p ₁ at the center position c of the back 11, each of these support portions 14, 15 and the other end edge portion 10b intersect with each other at positions p ₃ and p ₄ which are located at predetermined portions that contact the side of the waist 100 of the wearer of the main body portion 10, that is, at a portion outside the back portion 11 of the main body portion 10. Although it is configured, the present invention is not limited thereto, and the portions p ₃ and p ₄ where the support portions 14 and 15 and the other end edge portion 10b intersect are respectively positioned on the back portion 11 as shown in FIGS. It can also be configured. Further, as shown in FIGS. 22 to 25, the portions p ₃ and p ₄ where the respective support portions 14 and 15 and the other end edge portion 10b intersect with each other are divided into two support portions 16 and 17 forming a second set. Can also be arranged so as to overlap with each of the other edges 10b.

  In addition, in the supporter according to the embodiment, each of the back portions 11 extends over a predetermined range on both sides of the back portion center position c in the longitudinal direction of the main body portion (strides the center position), and is symmetrically arranged with the center position c interposed therebetween. As a set of two support portions, a set of two support portions 14 and 15 intersecting at a first predetermined position p1 at the center position c, and two support portions 16 intersecting at a second predetermined position p2 at the center position c, However, the present invention is not limited to this, and a set of two support portions that intersect at a predetermined position in the center position is divided into three groups as shown in FIGS. 26 to 29, for example. By providing a plurality of sets as described above, it is also possible to adopt a configuration in which the support portions form a small interval at the upper portion (one end portion side) of the back portion 11.

  Also in this case, as in the above-described embodiment, the expansion / contraction section 10c finely divided by the support portions is arranged on the upper portion of the back portion 11, so that the expansion / contraction section in the upper portion of the back portion 11 is larger than the upper portion. It is possible to create a state in which the upper part of the back part 11 that is difficult to extend is deformed inward relative to the lower part of the back part 11 by making it smaller than the lower part (the other edge part side) of the back part 11 in which 10d is arranged.

  In the supporter of the present invention, whether or not there is a difference in the degree of expansion or contraction in the vertical direction of the back portion due to the arrangement of a plurality of support portions over a predetermined range on both sides of the central position of the back portion in the longitudinal direction of the main body portion in the back portion. When the supporter was extended by applying a tensile force, the magnitude of the force applied to the upper and lower sides of the supporter and the amount of extension of the upper and lower parts were measured and verified and evaluated.

  As a supporter to be measured, as in the above embodiment, the knitted fabric is knitted with warp knitting, the knitting fabric knitting direction is the longitudinal direction of the supporter, the main body portion is formed with one knitted fabric, and the support portion is also combined And made a supporter. And, in each of the upper part of the back (the range part having a width of 50 mm from the upper side to the short side) and the lower part (the range part having a width of 50 mm from the lower side to the short side), the tensile force is applied in the longitudinal direction of the supporter. Each time the elongation amount reached a predetermined value set in advance, the tensile force at that time was measured and recorded.

Specifically, the position at which the supporter is gripped by the tensile tester is a position that is equidistant from the center position (c) of the back part of the supporter in an undeformed state to the left and right (longitudinal direction), and the distance between them is 100 mm. Set each location and gradually separate the two gripped locations so that the pulling speed is 300 mm / min. Every time the change in the grip position interval, that is, the amount of extension of the upper or lower portion of the back increases by 2 mm The magnitude of the applied tensile force was measured.
The measurement results are shown in Table 1. In Table 1, “upper” indicates that the upper part of the back of the supporter is the measurement target, and “lower” indicates that the lower part of the supporter is the measurement target.

  FIG. 30 is a graph plotting the relationship between the amount of extension of the upper and lower back portions of the supporter shown in Table 1 and the tensile force. In the graph of FIG. 30, the horizontal axis represents the amount of elongation (unit: mm), and the vertical axis represents the tensile force (unit: N).

  According to Table 1 and FIG. 30, the measurement results of the magnitude of the tensile force at each reaching the extension amount are larger for the lower part of the backer than for the lower part of the supporter. From these measurement results, the magnitude of the tensile force applied to produce the specified amount of extension differs between the top and bottom of the back, and in order to produce the same amount of extension at the top and bottom, it is necessary to apply a greater tensile force at the top than at the bottom. I understand that. This indicates that when the same tensile force is applied to the upper and lower portions of the back, a larger amount of elongation can be obtained at the lower portion.

  In the normal wearing state of the supporter, since the tensile force in the longitudinal direction of the main body transmitted to the back through the left and right extending parts is similarly applied above and below the back, the amount of extension of the lower back is greater than the upper back, The extension amount of the upper part of the back part is suppressed relative to the lower part of the back part.

  And in this supporter wearing state, while receiving the force to extend in the longitudinal direction of the main body part, the upper part of the back part is restrained from being stretched against the lower part of the back part that protrudes outward along the lower part of the back of the waist. It is obvious that the displacement is relatively inward of the curve because it cannot follow the deformation, and as a result, it can be seen that the upper back portion reaches a state along the constricted portion of the back surface at the upper waist portion.

  As described above, according to the present invention, the arrangement of the plurality of support portions on the back portion of the main body portion constituting the supporter generates a plurality of expansion / contraction sections divided by each support portion, and the back portion upper portion (one end). The state where the plurality of expansion / contraction sections near the edge are made smaller than the expansion / contraction section at the lower back (near the other edge), and the degree of expansion / contraction at the upper part of the back is less than the degree of expansion / contraction at the lower part of the back. Thus, the upper back portion can be relatively deformed inward with respect to the lower portion while the supporter is worn, and the upper back portion can be brought into close contact with the constricted portion of the upper back of the waist portion. Therefore, it is clear that the stretched state of the entire back portion can follow the waist back shape without fail and the back portion can be surely brought into contact with the back surface of the waist, and the waist can be appropriately supported by the supporter of the present invention.
