Description

The present invention relates to a supporter to be worn on the human body, and in particular to a supporter for the lumbar region that has a size similar to a corset and is worn around the waist, restricting movement of the lumbar region and reducing the burden on the lumbar region when moving the body. Regarding supporters.

BACKGROUND OF THE INVENTION Supports that are attached to the joints of a person's body (upper and lower limbs and torso) or a predetermined area near the joints to hold and protect the attached parts and reduce the burden during activities have been widely used.

In particular, supports that have a band-like structure and are attached to the lumbar region by wrapping around them apply pressure and increase intra-abdominal pressure to support and protect the lumbar vertebrae, as well as excessive backbending and rotation that can lead to pain. By restricting the wearer's lower back area during daily activities or sports-related movements, this reduces the burden on the lower back area and suppresses pain, and various types have been proposed. There is. An example of such a conventional lumbar supporter is one disclosed in Japanese Patent Application Laid-open No. 2013-138823.

JP2013-138823A

Conventional lumbar supports having a band-like structure have a structure as shown in the above-mentioned patent document, and have the flexibility to be wrapped around the waist as a whole, while being able to restrict the movement of the lumbar region. In addition to the belt-shaped main body portion, an auxiliary band is provided to strengthen the tightening force.

These supports do not require rigid members (pillars, stays) that restrict the movement of the lower back by ensuring a certain level of rigidity, and do not require the supporter fabric to be integrated with the supporter, allowing the lower back to be properly supported without causing any discomfort to the wearer due to the rigid members. It was something that could be supported.

However, the conventional lumbar supports do not have a vertical width that can cover the entire lumbar vertebrae, and were not intended to protect the entire lumbar vertebrae like a medical corset.

Some users may require a wider supporter, like a medical corset, that supports the entire lumbar vertebrae and reduces the burden on it, so we developed a new supporter that meets these demands. development is required.

When forming a wide supporter similar to a corset that protects the entire lumbar vertebrae, it is conceivable to apply the structure of the conventional lumbar supporter as shown in the above-mentioned patent document as is. In that case, if only the width of the conventional supporter in the vertical direction is expanded to suit the purpose, modification is minimized and it is desirable from a cost standpoint.

However, the conventional supporter has a structure in which one end of the two auxiliary band parts is fixed to the upper end of the back rest, and the other end is fixed to the lower end of the back rest. As the vertical width of the backrest increases, the relative positional relationship between the backrest and the two auxiliary bands fixed to it changes, and the overlapping area of each auxiliary band becomes narrower relative to the backrest. Therefore, unless special improvements are made, such as replacing each auxiliary band with a wider one and widening the area overlapping the back rest, the effect of pressing the back rest with each auxiliary band will not be as good as in the conventional case. However, the problem was that it could not be obtained in the same way.

In addition, in a conventional supporter, if only the vertical width of the backrest section were widened, the distance between the upper and lower ends of the backrest would become wider, and the distance between the fixing positions of each auxiliary band section would also become wider. . For this reason, when each auxiliary band part is in a tensioned state, the pressing force from each auxiliary band part is distributed and applied to the back rest part, and the pressing force is not applied to the center of the back part enough, making it difficult to wear. The supporting force of the backrest against the person's lower back is reduced. In addition, because the intersection of the two auxiliary bands moves from the upper side of the back rest and is closer to the center of the back rest, the effect of pressing down on the upper part of the back rest at the intersection is weakened, and the back rest becomes weaker. The problem has been that the backrest part may float away from the wearer's back on the upper side of the part, and the backrest part may not be able to sufficiently support the wearer's lower back.

The present invention has been made to solve the above problem, and even if the style is similar to a medical corset in which the vertical dimensions of the back are large, the back is brought into close contact with the back of the wearer's waist to prevent it from lifting from the back. To provide a supporter capable of properly supporting a wearer's lumbar region.

The supporter according to the present invention is a substantially belt-shaped lumbar supporter that is worn around the lumbar region, and includes a back portion that abuts the back side of the lumbar region that includes at least a predetermined range of the lumbar vertebrae of the wearer, and a supporter provided on both sides of the back portion. a main body formed as a substantially band-shaped continuous body with an extending portion extending from the main body; and a first band-like body having elasticity in the longitudinal direction, both ends of which are fixed to the back of the main body; An auxiliary band section that is folded a predetermined number of times so that the folded section is located outside the back of the main body section, and is disposed overlapping the back in a state where it is crossed one or more times on the back; and the auxiliary band section. A plurality of substantially annular connecting rods are disposed in the bent portion so as to be movable relative to the auxiliary band portion so that the auxiliary band portion is inserted loosely inside the bent portion, and a plurality of second band-shaped bodies are provided. , a plurality of adjustment band parts, each of which is loosely inserted into each connecting link part disposed on the auxiliary band part, has one end fixed to the extension part of the main body part, and has an engaging part attached to the other end. The extending portion of the main body portion includes a stretchable portion located near the back in the longitudinal direction of the extension length and having stretchability, and a non-stretchable portion located on a side away from the back and not having stretchability. The adjustment band part has one end fixed to the non-stretchable part of the extension part, and the other end of the adjustment band part to be fastened to an engaged part provided other than the stretchable part of the extension part. a plurality of diagonal sections, each of which is a section where the auxiliary band section diagonally crosses the back section and intersects with another section of the auxiliary band section; and a plurality of diagonal sections that cross the back section left and right and other sections of the auxiliary band section. and one crossing section which is a section that does not intersect.

As described above, according to the present invention, for the auxiliary band section which is disposed overlapping the substantially belt-shaped main body section and which has been bent multiple times to form a diagonal section and a transverse section, the folded section of the auxiliary band section is When wearing a supporter in which the adjustment band parts are connected via the connecting link part and the auxiliary band is pulled forward by the adjustment band part, the adjustment band part and the auxiliary band part are in tension, and the slanted part of the auxiliary band part By pressing the back of the main body at the intersecting part and the transverse part of the row part, each part corresponds to a different three-dimensional shape in the vertical direction on the back side of the waist, and the intersecting part of the auxiliary band part intersects with the diagonal part. The shape of the back can be made to follow the shape of the back surface of the lumbar region by pushing the back region with the upper part, and the back region can be appropriately brought into contact with the back surface of the wearer's lumbar region to reliably support the lumbar vertebrae, thereby suppressing the burden on the lumbar region. Furthermore, by forming the auxiliary band portion, which is overlapped on the back and arranged in a predetermined manner, from only one band-shaped body, the supporter structure can be simplified and manufacturing costs can be suppressed.

In addition, since each part of the auxiliary band part, except for the fixed ends, is in a floating state with respect to the back, the tension generated by pulling each adjustment band part is applied to both the left and right sides of the auxiliary band part, tightening each other. The auxiliary band section can securely tighten and support the lower back, and even if the tension applied by the adjustment band section is slightly different between the left and right sides, the common auxiliary band section equalizes the force, allowing for effortless support. This makes it possible to avoid a situation where the auxiliary band section is individually expanded and contracted on both sides of the fixed point, resulting in imbalanced tension, as would be the case if the auxiliary band section were fixed to the back.

Further, the supporter according to the present invention may include a plurality of belt loop-shaped guide portions, which are arranged on both sides of the back portion and allow portions of the auxiliary band portion in the vicinity of the bent portion to be loosely inserted therein, if necessary. It is something.

As described above, according to the present invention, belt loop-like guide parts are provided on both sides of the back, and the auxiliary band part passed through the guide parts is restrained so as not to be largely displaced, so that the adjustment band part can be moved to provide assistance. Even if force is applied to the band part, the overall arrangement of each band part will be maintained without shifting, and even if force is applied to the adjustment band part on the left and right sides, the layout of each band part will be symmetrical. The body does not collapse, ensuring appropriate support for the lumbar region.

Further, the supporter according to the present invention may optionally include a pressing core made of a non-stretchable plate-like body, and the back portion may have a substantially bag-like structure that accommodates the pressing core inside; The pressing core part is provided with a pair of substantially linear notches cut out from both left and right sides in the vertically intermediate part, and the auxiliary band part connects the intersection part of the diagonal part to the pressing core part of the back part. is arranged so as to overlap one of the upper and lower parts of the pressing core separated by a notch, and the transverse part is arranged so as to at least partially overlap the other of the upper and lower parts of the pressing core. It is.

As described above, according to the present invention, the back part has a substantially bag-like structure, the pressing core part is housed inside the back part, a notch part is provided in the middle part of the pressing core part, and the parts are separated by this notch part. The bending or twisting of one of the upper and lower parts of the pressing core part is allowed, and the diagonal part of the auxiliary band part overlaps one of the upper part and the lower part of the pressing core part, and the transverse part is on the other side. By overlapping each part of the pressing core with each part of the auxiliary band when the supporter is worn, the back maintains its overall shape with the pressing core, while the auxiliary band crosses the back when the supporter is worn. At this point, the entire pressing core is pressed to bring the back into contact with the waist, while one of the pressing cores that is pressed at the intersection of the diagonal parts of the auxiliary band changes direction relative to the other pressing core. This causes the back to conform to the shape of the back surface of the lumbar region, promotes close contact between the back and the back surface of the lumbar region, appropriately supports the lumbar region, and further reduces the burden on the lumbar region.

Further, the supporter according to the present invention may include, as necessary, a transverse portion in the auxiliary band portion and an adjustment band portion loosely inserted into the connecting link portions provided at each of the bent portions at both ends of the transverse portion. , the predetermined section from the loosely inserted part to the other end continues in a line under tension when the supporter is worn with the engaging part at the other end of the adjustment band part being engaged with the engaged part. It is an arrangement.

As described above, according to the present invention, when the supporter is worn, while the auxiliary band portion and the adjustment band portion are in a tensioned state, the transverse portion of the auxiliary band portion and the portion near the other end of the adjustment band portion form a line. By arranging the adjustment band, the force applied to the adjustment band to lock the other end of the adjustment band can be easily transmitted to each band in the linear arrangement, and each band can be moved without force loss. The tension of each band part can be efficiently applied to the back side of the waist region to support the waist region, and the force applied by the wearer to the adjustment band part when wearing the belt can also be suppressed.

Further, in the supporter according to the present invention, if necessary, at least the elastic portion of the extension portion may include a strip-shaped lower fabric portion having elasticity and a lower fabric portion having elasticity and a lower elastic resistance than the lower fabric portion. It has a structure in which small upper fabric portions are arranged one above the other so as to partially overlap.

As described above, according to the present invention, the extension part is formed by a combination of the upper fabric part and the lower fabric part, and the stretchable upper fabric part has a higher stretch resistance than the lower fabric part, which also has elasticity. By making the upper part of the extension part easier to deform when the supporter is being worn, even if the upper part of the extension part reaches the wearer's ribs due to the physique of the wearer wearing the supporter, the lower part of the fabric can be easily deformed. While ensuring tightness to reliably support the lower back, the upper fabric part, which is easily deformed, prevents excessive tightening of the lower ribs and gently surrounds them, so that the lower ribs do not feel pain due to tightening. be able to.

(First embodiment of the present invention)
EMBODIMENT OF THE INVENTION Hereinafter, the supporter based on the 1st Embodiment of this invention is demonstrated based on said FIGS. 1 thru|or 12.

In each of the above figures, the supporter 1 according to the present embodiment is a supporter for the lower back that is worn around the waist, and more specifically, it is a continuous body having a back part 11 and extension parts 12 and 13 in the form of a substantially belt-like shape. A main body part 10 formed, an auxiliary band part 30 formed of a stretchable band-like body and disposed overlappingly on the back part 11 of the main body part 10, and an auxiliary band part 30 disposed so as to be slidable with respect to the auxiliary band part 30. A pair of substantially annular connecting bars 41 and 42, and another band-shaped body loosely inserted into each of the coupling bars 41 and 42, and one end of which is fixed to the extending parts 12 and 13 of the main body 10. This configuration includes adjustment band portions 51 and 52.

The main body part 10 has a central back part 11 that comes into contact with the back side of the lumbar part 100 that includes a predetermined range of the wearer's lumbar vertebrae 101, and extension parts 12 and 13 arranged on both left and right sides of this back part 11. The structure is formed as a substantially belt-shaped continuous body.

The main body part 10 has a symmetrical shape with the center position of the back part 11 in the left-right direction as the center of symmetry, and is worn so as to be wrapped around the waist part 100 of the wearer with the back surface (see FIG. 2) in contact with the wearer's waist part 100.

The back part 11 and the extension parts 12 and 13 are arranged so that a predetermined area adjacent to each other is sandwiched between the front and back sides of the main body part 10 by a narrow band material 14 such as grosgrain tape, and the front and back band materials are They are connected by sewing the 14 edges. In particular, the back side facing the wearer may be made of a strip material having an anti-slip function.

In addition, the edges of the main body 10 are located at the edges of the back 11, the extensions 12, 13, and the band material 14, and edge materials 15 such as binder tape are sewn to sandwich these edges. The edges may be treated to prevent fraying at the cut edges or to improve the aesthetic appearance through decoration. In particular, if the edges of the extensions 12 and 13 are sewn with the edge material 15 using zigzag stitches, adjacent seams will not be crowded together, and the extensions 12 and 13 will be able to expand and contract in the longitudinal direction. It is preferable because it does not suppress the sex.

The back part 11 is formed into a symmetrical substantially hexagonal shape, and has a substantially bag-like structure in which a front side (outside when worn) fabric and a back side (inside when worn) fabric are overlapped, with a storage space between each piece of fabric. This is the configuration that will be used. Note that this back portion 11 is illustrated as being in contact with the entire range of lumbar vertebrae (first lumbar vertebrae (L1) to fifth lumbar vertebrae (L5)) 101 on the back side of the lumbar region (see FIG. 8); However, if the back part is formed so that it can come into contact with the back area including at least the fourth lumbar vertebrae (L4) and the fifth lumbar vertebrae (L5) in the lumbar region, the lumbar region can be supported without problems. can.

Extending portions 12 and 13 are connected and integrated on the left and right sides of this back portion 11. The upper and lower portions of the back portion 11 are formed in a shape that smoothly continues with the upper and lower portions of the extension portions 12 and 13, respectively. If the back part 11 is formed to have a wide width in the vertical direction (for example, 19 cm to 25 cm), it can correspond to the size of the wearer's lumbar vertebrae and reliably support the lumbar vertebrae like a corset. .
Further, inside the back portion 11 having a substantially bag-like structure, a pressing core portion 60 made of a non-stretchable plate-like member is accommodated and disposed.

Specifically, the pressing core part 60 is made of a relatively hard thin plate material, such as a synthetic resin panel, which has a strength that can be bent by human force but is difficult to bend. By being housed inside, it is possible to suppress excessive deformation of the back portion 11 when worn. However, if the fabric that makes up the back part itself has a suitable hardness (bending resistance) that does not bend easily and maintains the shape of the surface, and can disperse the pressing force on the surface and transmit it to the waist side, It is also possible to have a configuration that does not use a pressing core. In that case, the back portion 11 does not have to have a substantially bag-like structure. In addition, instead of accommodating and arranging the pressing core part 60 inside the back part 11, it may be arranged integrally with the back part 11 in a state where the pressing core part 60 is partially or completely exposed. In this case, the back portion 11 does not have to have a substantially bag-like structure.

The pressing core portion 60 is provided with a pair of notches 61 cut out in a substantially linear shape from both left and right sides in the vertically intermediate portion. By separating the upper and lower parts of the pressing core part 60 with a part remaining at this notch part 61, the relative bending and twisting of the upper part with respect to the lower part can be controlled within the deformable range of the thin plate material forming the pressing core part. It will be allowed. As a result, the back part 11 maintains its overall shape with the pressing core part 60, and while the back part 11 is pressed as a whole together with the pressing core part 60 and comes into contact with the waist part in the worn state, the upper or lower part of the pressing core part 60 can The back part 11 can be flexibly adapted to the shape of the back surface of the lumbar region, such as by changing the direction of the pressing core to the other side (lower or upper part) to make the back region 11 more closely conform to the shape of the back surface of the lumbar region. I can make you come into close contact with me.

Moreover, as shown in FIG. 6, the pressing core part 60 has a shape in which a recessed part 62 is provided at the center of the upper end part and the lower end part, as well as the left and right notch parts 61. As a result, even when the pressing core 60 is curved, the centers of the upper and lower ends of the pressing core 60, which are relatively retracted from other parts, can be adjusted to the wearer's spine as in the case where no recess is provided. This prevents local pressure stimulation from being applied to the skin on the back side of the body, and the wearer does not feel any pain.

The extending portions 12 and 13 include elastic portions 12d and 13d that are located closer to the back portion 11 in the longitudinal direction of the extension and have elasticity in the longitudinal direction of the extension, and elastic portions 12d and 13d that are located on the side away from the back portion 11. The structure includes non-stretchable parts 12e and 13e that do not have stretchability.

Specifically, the extending portions 12 and 13 include stretchable band-shaped lower fabric portions 12a and 13a, and an upper fabric portion 12b that is stretchable and has lower stretching resistance than the lower fabric portions 12a and 13a. , 13b are arranged vertically in a partially overlapping manner, and one end is connected and integrated with the left and right sides of the back portion 11. In contrast to the band-shaped lower fabric parts 12a, 13a, the upper fabric parts 12b, 13b are approximately triangular in shape, and the extension part as a whole has a tapered shape that becomes narrower toward the other end farther away from the back part 11.

A non-stretchable sheet-shaped attached portion 22 is attached to the other ends of the extension portions 12 and 13 remote from the back portion 11 by overlapping and sewing. The portions of the extending portions 12 and 13 that overlap with the attached portion 22 become non-stretchable portions 12e and 13e, and the remaining portions maintain the elasticity of the lower fabric portions 12a and 13a and the upper fabric portions 12b and 13b. This is a mechanism that becomes elastic parts 12d and 13d.

In other words, the extending portions 12 and 13 are formed by disposing lower fabric portions 12a and 13a and upper fabric portions 12b and 13b, which form stretchable portions 12d and 13d, and these lower fabric portions 12a and 13a and the upper fabric portions 12a and 13b are disposed. The attached portion 22, which is formed with less elasticity than the fabric portions 12b and 13b, is overlapped and sewn integrally with the other end of the extension portion to form the attached portion of the extension portions 12 and 13. The portions overlapping with 22 are configured as non-stretchable portions 12e and 13e.

The attached part 22 may be made of a fabric with a structure that suppresses elasticity and has excellent breathability. If a fabric with a structure with excellent breathability is adopted, it can be attached by overlapping it on the extension part. The non-stretchable parts 12e and 13e also have sufficient air permeability, and even in a situation where both ends of the main body part 10 overlap when the supporter is worn, air permeability can be ensured and the feeling of wearing can be improved.

The lower fabric parts 12a, 13a and the upper fabric parts 12b, 13b, which constitute the extension parts 12, 13, are made of fabric that has elasticity in the longitudinal direction but has almost no elasticity in the transverse direction. Ru. Note that the lower fabric portions 12a, 13a and the upper fabric portions 12b, 13b both have greater elasticity than the auxiliary band portion 30 in the longitudinal direction.

The upper fabric parts 12b and 13b of the extension parts 12 and 13 are made to have lower stretch resistance than the lower fabric parts 12a and 13a, so that the upper part of the extension parts can easily deform when the supporter is worn. Even if the upper portion of the extension reaches the wearer's ribs 104 depending on the physique, the lower fabric portions 12a and 13a maintain a tight state and reliably support the waist portion 100, while the upper fabric portion, which is easily deformed, 12b and 13b can prevent the lower part of the ribs 104 from being excessively tightened and can surround the lower part of the ribs 104 gently, so that the patient does not feel pain due to the tightening of the lower part of the ribs 104.

In addition, an engaging portion 12g is attached to the back side of the other end of one of the extending portions 12 and 13 as the left and right ends of the main body portion 10, and Since the other end of the extension portion 13 can be attached to the attached portion 22 on the front surface side, both ends of the main body portion 10 can be overlapped and connected, and the main body portion 10 can be attached to the waist region 100 of the wearer. It is possible to maintain the wearing condition by wrapping it around the body.

Note that the locking part is not limited to a configuration in which it is attached to the right extension part 12, but the locking part is attached to the back surface side of the other end of the left extension part 13, and this is attached to the right extension part 12. 12, the two ends of the main body 10 can be overlapped and connected so that the left extension 13 is on the front side, and by this connection, the main body The structure may be such that the portion 10 remains wrapped around the wearer's waist 100.

The auxiliary band section 30 is formed of a band-shaped body that is stretchable in the longitudinal direction, and has both ends fixed to the upper portions of both sides of the back section 11 of the main body section 10, and has bent sections 31 and 32 located on the outside of the back section 11. In this way, it is folded twice and crossed once on the back part 11, and is arranged in an overlapping manner on the back part 11.

This auxiliary band section 30 has three sections divided by two bent sections 31 and 32, namely, two oblique sections 33 which are sections that diagonally cross the back section 11 and intersect with other parts of the auxiliary band section 30. , 34, and one transverse portion 35 which is a section that crosses the back portion 11 from side to side and does not intersect with other portions of the auxiliary band portion 30.

For this auxiliary band part 30, on both sides of the back part 11, there are belt loop-shaped guide parts 16 into which portions of the cross section 35 of the auxiliary band part 30 near the respective bent parts 31 and 32 are loosely inserted. This is a mechanism to hold the auxiliary band portion 30 so that it does not easily shift.

The guide portion 16 is formed of a narrow band material such as grosgrain tape. In detail, a part of one band of a predetermined length is folded back and the part of the band 14 that is sewn to the back 11 and the extension parts 12 and 13 overlaps with the cross section 35 of the auxiliary band part 30 and the upper part thereof. , the folded parts of the strips are sewn together with the folded parts facing downwards.

The auxiliary band part 30 positioned by this guide part 16 has the diagonal parts 33 and 34, including the intersection thereof, the upper part of the pressing core part separated by the notch part 61 in the pressing core part 60 in the back part 11, and The lower part is arranged so as to overlap with the upper part, and the transverse part 35 is arranged so as to partially overlap with the lower part of the pressing core part 60. With respect to the back part 11, the position where the diagonal parts 33 and 34 overlap is at the top of the back part 11, and the position where the crossing part 35 overlaps is at a slightly lower center of the back part 11.

The cross section 35 of the auxiliary band section 30 is held through the guide section 16, and the bent sections 31 and 32 of the auxiliary band section 30 are positioned near the guide section on the outside of the back section 11, so that the auxiliary band In the section 30, the wearer can press the other end of each adjustment band section 51, 52 when wearing the supporter from a pre-wearing state in which no tensile load is applied from each adjustment band section 51, 52 via each connection link section 41, 42. When pulling the wearer forward, the stretching direction of the auxiliary band section 30 is specified, the resistance at the beginning of the extension of the auxiliary band section 30 can be reduced, and the wearer can smoothly move each adjustment band section 51, 52.

Further, both ends of the auxiliary band portion 30 are sewn at the upper part of each side of the back portion 11, with most of the ends being sandwiched between the band material 14 and the band material forming the guide portion 16, and the remaining end portions being sewn. This part is fixed to the back part 11 by being sandwiched between the upper edge of the back part 11 and the edge material 15 and sewn.

The positions at which both ends of the auxiliary band portion are fixed are not limited to the upper side portions of the back, but may be at the upper edge of the back. Further, in order to simplify the fixing structure by sewing, both ends may be separated from the upper edge of the back and fixed only to the side of the back, or conversely, it may be fixed only to the upper edge of the back.

The connecting parts 41 and 42 have elongated substantially annular parts, and are arranged relative to the auxiliary band part 30 so that the auxiliary band part 30 is loosely inserted into the bent parts 31 and 32 of each auxiliary band part 30. It is configured to be movably arranged.

In detail, each of the connecting links 41 and 42 is formed as a so-called Japanese link made of synthetic resin, for example, and has a hole through which the auxiliary band part 30 is passed and a hole through which the adjustment band parts 51 and 52 are passed. A hole is provided in each case.

As shown in FIG. 1, the first connecting link part 41 has a first long hole 41a, which is a through hole through which the auxiliary band part 30 passes, corresponding to the width and thickness of the auxiliary band part 30, and a first elongated hole 41a, which is a through hole through which the auxiliary band part 30 passes. Corresponding to the width and thickness of the adjustment band part 51, second elongated holes 41b, which are through holes through which the first adjustment band part 51 passes, are provided in parallel.

Here, a through hole corresponding to the width and thickness of the auxiliary band part 30 and the first adjustment band part 51 is a through hole that does not affect the relative movement of the connecting link part 41 while slidingly contacting each band part. (Elongated holes 41a, 41b) means a hole of a size that does not twist each band part (auxiliary band part 30, first adjustment band part 51) itself.

For example, by making the length of the elongated hole 41a substantially the same as the width of the auxiliary band portion 30, and by making the length of the elongated hole 41b substantially the same as the width of the first adjustment band portion 51, the auxiliary band portion 30 The resultant force generated from the first adjustment band part 51 to the first connection link part 41 can be balanced, and the width of the elongated holes 41a and 41b can be adjusted by adjusting the width of each of the auxiliary band part 30 and the first adjustment band part 51. By increasing the thickness by 1.5 to 2.0 times, it is possible to prevent the auxiliary band portion 30 and the first adjustment band portion 51 from twisting. By appropriately setting the width and length of the elongated holes 41a and 41b for each band portion in this way, when the supporter 1 is attached, the direction in which the other end of the first adjustment band portion 51 is moved is set to the first adjustment. Even if one end of the band portion 51 is shifted vertically with respect to a certain direction, the first adjustment band portion 51 can be pulled without causing the auxiliary band portion 30 and the first adjustment band portion 51 to become twisted. can.

As shown in FIG. 1, the second connecting link part 42 has a first elongated hole 42a, which is a through hole through which the auxiliary band part 30 passes, corresponding to the width and thickness of the auxiliary band part 30; A second elongated hole 42b, which is a through hole through which the second adjustment band portion 52 passes, is provided in parallel corresponding to the width and thickness of the adjustment band portion 52.

Here, a through hole corresponding to the width and thickness of the auxiliary band part 30 and the second adjustment band part 52 is a through hole that does not affect the relative movement of the connecting link part 42 while slidingly contacting each band part, and (Elongated holes 42a, 42b) means a hole of a size that does not twist each band part (auxiliary band part 30, second adjustment band part 52) itself.

For example, by making the length of the elongated hole 42a substantially the same as the width of the auxiliary band portion 30, and making the length of the elongated hole 42b substantially the same as the width of the second adjustment band portion 52, the auxiliary band portion 30 The resultant force generated from the second adjustment band portion 52 to the second connection link portion 42 can be balanced, and the width of the elongated holes 42a and 42b can be adjusted by adjusting the width of each of the auxiliary band portion 30 and the second adjustment band portion 52. By increasing the thickness by 1.5 to 2.0 times, it is possible to prevent the auxiliary band portion 30 and the second adjustment band portion 52 from twisting. By appropriately setting the width and length of the elongated holes 42a and 42b for each band portion in this way, when the supporter 1 is attached, the direction in which the other end of the second adjustment band portion 52 is moved is set to the second adjustment band portion 52. Even if one end of the band portion 52 is shifted vertically with respect to a certain direction, the second adjustment band portion 52 can be pulled without causing the auxiliary band portion 30 and the second adjustment band portion 52 to become twisted. can.

The adjustment band parts 51 and 52 are made of band-shaped bodies having a stretchability smaller than that of the auxiliary band part 30, and are loosely inserted into the connecting link parts 41 and 42 provided on the auxiliary band part 30, respectively, and have one end attached to the main body. It is fixed to the extending parts 12 and 13 of the part 10, and the engaging part 21 can be attached to the other end.

The first adjustment band section 51 is formed in the shape of a flat band, such as a so-called PP tape woven with polypropylene thread and polyester thread, and one end of the first adjustment band section 51 is attached to the right side of the extending section 12 of the main body section 10. It is fixed to the elastic part 12e, is loosely inserted into the elongated hole 41b of the first connecting link part 41 on the bending part 31 of the auxiliary band part 30, and is bent opposite to the bending part 31 of the auxiliary band part 30. , the surface of the engaging portion 21 at the other end is directed toward the surface of the right extension portion 12 of the main body portion 10 .

Then, the first adjustment band section 51 attaches the engaging section 21 attached by sewing or the like to the other end of the extending section 12 other than the elastic section of the extending section 12, specifically, the right extending section 12 of the main body section 10. It is possible to engage with the engaged part 22 provided in the non-stretchable part 12e.

For example, one end of the first adjustment band portion 51 may be fixed between the lower fabric portion 12a forming the right extension portion 12 of the main body portion 10 and the attached portion 22. By sandwiching the lower fabric portion 12a and the attached portion 22, one end can be sewn to the attached portion 22 forming the non-stretchable portion 12e. can. However, the present invention is not limited to this, and one end of the adjustment band portion 51 may be fixed to the surface of the attached portion 22 forming the non-stretchable portion 12e by sewing or the like. In this case, another secured portion is provided on the surface of one end of the adjustment band portion 51, and the secured portion 21 at the other end of the adjustment band portion 51 is connected not only to the secured portion 22 but also to the adjustment band appearing on the surface. It is desirable that one end of the portion 51 can also be engaged.

Further, the other end of the first adjustment band portion 51 is thickened by attaching the engaging portion 21 overlappingly, and the first adjustment band portion 51 is attached from the elongated hole 41b of the first connecting link portion 41. This makes it difficult for the band portion 51 to come off, and allows the wearer to easily grasp the other end of the adjustment band portion 51 and handle it easily.

Like the first adjustment band part 51, the second adjustment band part 52 is formed in a flat band shape, and one end thereof is fixed to the non-stretchable part 13e of the left extension part 13 of the main body part 10, and the auxiliary band part 30 is loosely inserted into the elongated hole 42b of the second connecting link part 42 on the bending part 32 of the auxiliary band part 30, and is bent opposite to the bending part 32 of the auxiliary band part 30, so that the locking part 21 at the other end The surface is directed toward the surface of the left extension part 13 of the main body part 10.

The second adjustment band section 52 is configured to attach the engaging section 21 attached to the other end by sewing or the like to a part other than the elastic section of the extension section 13, specifically, the left extension section 13 of the main body section 10. It is possible to engage with the engaged part 22 provided in the non-stretchable part 13e.

For example, one end of the second adjustment band portion 52 may be fixed between the lower fabric portion 13a forming the left extension portion 13 of the main body portion 10 and the attached portion 22. By sandwiching the lower fabric portion 13a and the attached portion 22, one end can be sewn to the attached portion 22 forming the non-stretchable portion 13e. can. However, the present invention is not limited to this, and one end of the adjustment band portion 52 may be fixed to the surface of the attached portion 22 forming the non-stretchable portion 13e by sewing or the like. In this case, another secured portion is provided on the surface of one end of the adjustment band portion 52, and the secured portion 21 at the other end of the adjustment band portion 52 is connected not only to the secured portion 22 but also to the adjustment band appearing on the surface. It is desirable that one end of the portion 52 can also be engaged.

Further, the other end of the second adjustment band portion 52 is thickened by attaching the engaging portion 21 in an overlapping manner, and the second adjustment band portion 52 is attached from the elongated hole 42b of the second connecting link portion 42. This makes it difficult for the band portion 52 to come off, and the wearer can easily grasp the other end of the adjustment band portion 52 and handle it easily.

The hook surface of a hook-and-loop fastener, for example, is used for the engaging portion 21 at the other end of each adjustment band portion 51, 52. For example, a loop surface of a hook-and-loop fastener is used as the engaged portion 22 that pairs with the engaging portion 21 and allows the engaging portion 21 to be engaged.

As the attached part 22, for example, a fabric having a large number of loop structures on the surface such as a double raschel knitted fabric can be used, and by having a large number of loops, the adjustment band part that serves as the hook surface of the hook-and-loop fastener can be used. The engaging portions 21 at the other ends of 51 and 52 can be engaged easily.

The engaging portion 21 at the other end of each of these adjustment band portions 51, 52, the engaging portion 12g on the back side of the other end of the extension portion 12, and the other end portion of the extending portions 12, 13 to which these are engaged. The attached part 22 on the front side is not limited to the hook surface and loop surface of the hook-and-loop fastener, but as long as it can attach two overlapping parts, it can be attached to another attached part and the attached part. For example, a combination of wire fasteners (zippers, zippers), buttons and buttonholes, hooks (dot buttons, snaps), front buttons, buckles, strings and spindle stoppers, etc. may be used.

When the supporter 1 according to the present embodiment is placed on a flat surface and spread out, the engaging portion 21 at the other end of each adjustment band portion 51, 52 and the engaged portion 22 of each extending portion 12, 13 are connected to each other. When the attachment is released and a predetermined section of each adjustment band section 51, 52 from the part loosely inserted into the connecting link section 41, 42 to the other end (sections 51b, 52b near the other end) is not restrained, The sections 51b and 52b near the other end of the adjustment band portion extend toward the lower edges of the extensions 12 and 13, and the other ends thereof are arranged to protrude downward from the lower edges of the extensions. The other end sections 51b and 52b of each of the adjustment band parts 51 and 52 extend from the end of the auxiliary band part 30 fixed to the back part 11 to the respective bent parts 31 and 32 where the connecting link parts 41 and 42 are located. The diagonal portions 33 and 34, which are the sections, are arranged in a continuous line (see FIG. 4).

In this case, a predetermined section (sections 51a, 52a near one end) from one end fixed to the non-stretchable parts 12e, 13e of the extension part of the adjustment band parts 51, 52 to a part loosely inserted into the connecting link parts 41, 42. ) is also arranged in a line that continues with the transverse section 35, which is a section sandwiched between the respective bending sections 31, 32 where the connecting link sections 41, 42 are located in the auxiliary band section 30.

However, in the expanded state of the supporter 1, the sections 51b and 52b of the adjustment band sections 51 and 52 that are closer to the other end normally extend the extension of the main body section 10 while slightly bending the adjustment band section and the auxiliary band section. The sections 12, 13 and the sections 51a, 52a near one end of the adjustment band sections 51, 52 are arranged in a direction that all overlap, and the engaging section 21 at the other end is connected to the engaged section 22 of the extending sections 12, 13. (See Figure 1). Thereby, the supporter can be easily handled when folded and stored, and the shape after folding can be made compact.

On the other hand, a supporter wearing state in which the main body part 10 is worn around the waist of the wearer, and the engaging parts 21 at the other ends of the adjustment band parts 51 and 52 are engaged with the attached part 22 at the other end of the extension part. When tensile force is applied to the stretchable parts 12d and 13d of the extension parts 12 and 13 and the auxiliary band part 30, the tension between the auxiliary band part 30 and the adjustment band parts 51 and 52 is caused by deformation such as elongation in these parts. The positional relationship changes. Specifically, the sections 51b, 52b of each of the adjustment band sections 51, 52 near the other end and the cross section 35 of the auxiliary band section 30 are arranged to be continuous in a line while being stretched.
In addition, the sections 51a and 52a of the adjustment band sections 51 and 52 near one end and the oblique sections 33 and 34 of the auxiliary band section 30 are arranged to be continuous in a line while maintaining tension.

Next, the process of wearing the supporter based on the above structure and its effect on the body in the wearing state will be explained. As a premise, in advance, the engagement part 21 of the first adjustment band part 51 and the engaged part 22 of the right extension part 12 of the main body part 10 are released, and the second adjustment band part 52 is released. It is assumed that the engaging part 21 and the engaged part 22 of the left extension part 13 of the main body part 10 are in a disengaged state.

When wearing the supporter 1, the wearer first supports both ends of the supporter 1 with his hands and holds the back side of the back part 11 of the main body part 10 in contact with the back of the wearer's waist. Then, the wearer moves the left side portion of the main body 10 forward with the left hand when viewed from the wearer, stretches the left extension portion 13 diagonally downward as much as possible, and wraps it around the wearer's waist 100. Rotate it and hold it with your left hand.

Next, move the right side part of the main body part 10, which has the engaging part 12g on the back side, forward with your right hand, and while stretching the right side extension part 12 diagonally downward, wrap it around the waist part 100 of the wearer. Further, the engaging portion 12g at the end of the extending portion 12 is engaged with the engaged portion 22 on the surface of the left extending portion 13 held by the left hand, so that the main body portion 10 is temporarily fixed around the waist.

When both ends of the main body part 10 are wound around the waist part 100 in the correct direction and are engaged by the engaging part 12g and the attached part 22, the main body part 10 is placed continuously on the front side of the wearer, and when viewed from the front. It forms a shape that widens at the end. In this arrangement, the direction of expansion and contraction of the left and right extensions 12 and 13 is diagonally upward from the front abdomen to the side abdomen, and the front parts of the extensions 12 and 13 push up the abdomen from below, effectively reducing pressure in the abdominal cavity. It is possible to increase it.

At this stage of temporary fixation of the main body part 10, the auxiliary band part 30 is connected to the first adjustment band part 51 (first connection link part 41) and the second adjustment band part 52 (second connection link part 42). Since it is not receiving any tensile load from the body, it is in a relaxed state and does not press the back part 11.

However, in the back part 11, the elasticity in the longitudinal direction of the main body part 10 is suppressed by the internal pressing core part 60, so that the non-stretchable parts 12e, 13e at the other ends of the extension parts 12, 13 located in the front. At the same time, it functions as an anchor for the extendable parts 12d and 13d of the extension parts 12 and 13, which are extendable and retractable in the longitudinal direction of the main body part 10.

The wearer grips the section 51b near the other end of the first adjustment band section 51 with his right hand and the section 52b near the other end of the second adjustment band section 52 with his left hand, and then adjusts the first adjustment band section. 51 and the second adjustment band section 52 by pushing each hand forward.

In this case, the first connecting link section 41 follows the movement of the section 51b near the other end of the first adjustment band section 51, and slides on the first adjustment band section 51 as necessary to perform relative movement. Meanwhile, the right side of the auxiliary band section 30 that moves forward with respect to the back section 11 and has elasticity follows the movement of the first connecting link section 41 and extends forward.

Similarly, the second connecting link section 42 follows the movement of the section 52b near the other end of the second adjustment band section 52, and slides on the second adjustment band section 52 to move relatively as necessary. Meanwhile, the left side of the auxiliary band section 30, which moves forward with respect to the back and has elasticity, expands following the movement of the second connecting link section 42.

On the other hand, the first connecting link part 41, which receives a forward force from the first adjustment band part 51, and the second connecting link part 42, which receives a forward force from the second adjustment band part 52, each move forward. By restricting the movement of the auxiliary band section 30, the force applied to the first adjustment band section 51 and the second adjustment band section 52 can be applied even if one end of each adjustment band section 51, 52 is fixed. It also acts to relatively move the non-stretchable parts 12e, 13e of the left and right extension parts 12, 13 backwards. Therefore, a force acts on the stretchable parts 12d and 13d of the extension parts 12 and 13 in a direction that narrows the distance between the back part 11 and the non-stretchable parts 12e and 13e of the extension parts 12 and 13.

However, when wrapping the main body part 10 around the waist, the elastic parts 12d and 13d, which have higher elasticity than the auxiliary band part 30, are stretched to the limit of longitudinal extension, and then the main body part 10 Since the right side engaging part 12g is engaged with the left side engaged part 22 of the main body part 10 to keep the main body part 10 in a fixed state, before the fully extended telescopic parts 12d and 13d start to contract, The auxiliary band portion 30 begins to stretch, and the distance between the back portion 11 and the non-stretchable parts 12e, 13e can be narrowed by the stretch of the stretchable parts 12d, 13d, which prevents wrinkles from forming in the stretchable parts 12d, 13d. can be suppressed.

Note that the auxiliary band section 30 receives the force from the first adjustment band section 51 via the first connection link section 41 and the second adjustment band section 52 that receives the force via the second connection link section 42. While elongating due to the force from You will have to adjust it yourself so that the extension state is uniform.

In addition, since the guide parts 16 provided on both sides of the back part 11 restrain the auxiliary band part 30 so that it does not shift significantly, when force is applied to the auxiliary band part 30 by moving the adjustment band parts 51 and 52. However, the overall arrangement of each band section is maintained without shifting, and even if the adjustment band sections 51 and 52 are pulled on one side at a time, the symmetrical layout of each band section will not collapse and the waist will be adjusted properly. A good support condition can be ensured.

11 and 12, when the wearer has obtained the desired tightening feeling on the waist region, the wearer moves the engaging portion 21 of the first adjustment band portion 51 to the right side extension portion of the main body portion 10. At the same time, the second adjustment band section 52 is engaged with the engagement section 22 of the left side extension section 13 of the main body section 10 . In this way, the entire supporter can be placed along the surface of the body to complete the installation.

During installation, while the auxiliary band section 30 and the adjustment band sections 51 and 52 are in tension, the cross section 35 of the auxiliary band section 30 and the sections 51b and 52b near the other end of the adjustment band sections 51 and 52 are linearly aligned. Because of the arrangement, the force applied to the adjustment band parts 51, 52 in order to lock the other ends of the adjustment band parts 51, 52 to the attached part 22 can be easily transmitted to each band part in this linear arrangement. This allows each band section to be tensioned without causing any loss of force, and the tension of each band section can be efficiently applied to the back side of the waist region to support the waist region. , 52 can also be suppressed.

When the supporter is worn, the auxiliary band part 30 receives a tensile load from the first adjustment band part 51 via the first connection link part 41, and receives a tensile load from the first adjustment band part 51 via the second connection link part 42. It is in a tensioned state because it is receiving a tensile load from the band portion 52. As a result, a pressing force is applied from the tensed diagonal parts 33 and 34 to the upper part of the back part 11 where these parts intersect, and a pressing force is applied from the similarly tensed transverse part 35 to the lower center of the back part 11 where this is located.

Further, a pressing core 60 is housed inside the back portion 11, and a notch 61 is provided in the middle part of the pressing core 60, and one of the upper and lower parts of the pressing core 60 separated by the notch 61. The other side is allowed to bend and twist, and the oblique parts 33 and 34 of the auxiliary band part 30 overlap the upper part of the pressing core part 60, and the cross part 35 mainly overlaps the lower part, When the supporter is worn, each part of the pressing core part 60 is pressed by each part of the auxiliary band part 30.

In this way, while the back part 11 maintains its overall shape by the pressing core part 60, the pressing core part 60 is pressed as a whole by the cross section 35 of the auxiliary band part 30 to bring the back part 11 into contact with the waist part, while the auxiliary band part The upper part of the pressing core part 60 that is pressed at the intersection of the diagonal parts 33 and 34 of 30 changes its direction with respect to the lower part of the pressing core part 60, so that the upper part of the back part 11 can fit more closely along the waist part 100 at the waist part 100. The form of the back 11 can be made to follow the shape of the back of the lumbar region, which has a different three-dimensional shape in each part in the vertical direction, and the back 11 can be brought into proper contact with the back of the wearer's lumbar region, and the entire lumbar vertebrae 101 of the wearer can be It is possible to reliably support a wide range of the waist region 100 including the lower back region, thereby suppressing the burden on the waist region.

As described above, in the supporter according to the present embodiment, the auxiliary band section 30 is arranged to overlap the substantially band-shaped main body section 10 and has the oblique sections 33, 34 and the transverse section 35 formed by bending a plurality of times. On the other hand, the adjustment band parts 51 and 52 are connected to the bent parts 31 and 32 of the auxiliary band part 30 via the connecting parts 41 and 42, and the auxiliary band part 30 is pulled forward by the adjustment band parts 51 and 52. When the supporter is worn, the adjustment band parts 51 and 52 and the auxiliary band part 30 are in tension, and the back part 11 of the main body part 10 is , the back part 11 is pressed by the diagonal parts 33, 34 intersecting parts and the crossing part 35 of the auxiliary band part 30, corresponding to different three-dimensional shapes in the vertical direction on the back side of the waist part. The shape of the back part 11 can be made to follow the shape of the back of the lumbar region, and the back part 11 can be appropriately brought into contact with the back side of the wearer's lumbar region to reliably support the entire lumbar vertebrae, thereby suppressing the burden on the lumbar region. Further, by forming the auxiliary band portion 30 which is placed over the back portion 11 from only one band-shaped body, the supporter structure can be simplified and manufacturing costs can be reduced.

In addition, since each part of the auxiliary band part 30 is in a floating state with respect to the back part 11 except for the fixed ends, the tension generated by pulling each of the adjustment band parts 51 and 52 is common to both left and right sides of the auxiliary band part 30. In addition, the auxiliary band part 30 can securely tighten and support the waist area by the auxiliary band part 30, and the auxiliary band part 30 is common even if the tension applied by the adjustment band parts 51 and 52 is slightly different on the left and right sides. By equalizing the force, it can be supported without strain, and it avoids the situation where the auxiliary band part expands and contracts individually on both sides of the fixed point, resulting in imbalanced tension, as would be the case if the auxiliary band part was fixed to the back. can.

Note that in the supporter according to the embodiment, the extending portions 12 and 13 are formed by a combination of the lower fabric portions 12a and 13a, the upper fabric portions 12b and 13b, and the attached portion 22. However, it is not limited to the above, but it is also possible to layer a non-stretchable material such as an attached part on one stretchable fabric, or to combine a stretchable fabric that forms a stretchable part and a stretchable fabric that forms a non-stretchable part. It is also possible to connect and integrate fabrics that do not have the same by arranging them side by side and joining them together to form a continuous extension.

(Second embodiment of the present invention)
In the supporter according to the first embodiment, the auxiliary band portion 30 has both ends fixed to the upper portions of both sides of the back portion 11 of the main body portion 10, and has two oblique portions 33 and 34 that diagonally cross the back portion 11. A transverse part 35 that crosses the back part 11 from side to side is placed on the lower side, so that the intersection of the diagonal parts 33 and 34 overlaps the upper part of the back part 11, and the transverse part 35 is located at a slightly lower part of the center of the back part 11. Although the configuration is such that a pressing force is applied to the back portion 11 from the crossing portion of the diagonal portions 33 and 34 and the crossing portion 35, which are tense when worn, the second embodiment is not limited to this. As shown in FIG. 13, both ends of the auxiliary band part 30 are fixed to the lower part of both sides of the back part so that the two diagonal parts intersect at the lower part of the back part 11, and the transverse part 35 of the auxiliary band part 30 is It is also possible to support the guide part 16 so as to overlap the upper part of the back part 11 between the intersection of the diagonal parts and the upper edge of the back part 11.

In this case, when the supporter is worn, pressing force is applied from the tensed cross section 35 of the auxiliary band section 30 to the upper part of the back section 11 where this is located, and pressure is applied from the similarly tense diagonal sections 33 and 34 to the back section 11 where these intersect. Pressure force is applied toward the bottom of the center. As a result, the pressing core part 60 is pushed entirely at the intersection of the diagonal parts 33 and 34 of the auxiliary band part 30 to bring the back part 11 into contact with the waist, while being pushed by the crossing part 35 of the auxiliary band part 30. The upper part of the pressing core part 60 changes its direction with respect to the lower part of the pressing core part 60, so that the upper part of the back part 11 can fit more easily into the constriction of the back part of the upper part of the waist part 100, so that each part in the vertical direction has a different three-dimensional shape. The form of the back part 11 is made to follow the shape of the back part of the lumbar part, and as in the previous embodiment, the back part 11 is appropriately brought into contact with the back part of the wearer's lumbar part, thereby ensuring a wide range of the lumbar part 100 including the entire lumbar vertebrae 101 of the wearer. It can support the body and reduce the burden on the lower back.

(Third embodiment of the present invention)
In the first embodiment, the auxiliary band part 30 is bent twice and crossed once on the back part 11, and the two intersecting diagonal parts 33, 34 and the crossing part 35 are arranged so that the auxiliary band part 30 is bent twice and crossed once on the back part 11. However, the configuration is not limited to this, and the auxiliary band part is bent a predetermined even number of times so that the bent part is positioned outside the back part symmetrically with the back part as the center, and the back part is pressed. There are two or more sets of two diagonal parts that cross each other diagonally across the back, and these two or more sets of diagonal parts cross each other multiple times, and the diagonal part and the back of these multiple sets are crossed from side to side. It is also possible to have a configuration in which only one cross section presses against the back. For example, as shown in FIG. 14, the auxiliary band portion 30 is bent four times to arrange two sets of intersecting diagonal portions 33, 34, 38, 39. There may be two intersecting parts, and the back part 11 can be pressed by these and the crossing part 35. In this case, the connecting link portions 41, 42, 43, and 44 are also provided at the four bent portions of the auxiliary band portion 30, and a plurality of pairs of adjustment band portions 51, 52, 53, and 54 are also provided.

(Fourth embodiment of the present invention)
In the supporter according to the first embodiment, the pressing core part 60 is housed inside the back part 11 of the main body part 10, and is arranged so as to overlap with the diagonal parts 33, 34 and the transverse part 35 of the auxiliary band part 30. When the supporter is worn, each part of the pressing core 60 is pressed by each part of the auxiliary band part 30, and the pressed core 60 changes the shape of the back 11 while maintaining the overall shape of the back 11 with the pressing core 60. follows the shape of the back of the wearer's waist, and the back 11 is appropriately brought into contact with the back of the waist to reliably support the wearer's waist 100. In addition, as a fourth embodiment, A core similar to the pressing core 60 can also be configured to be applied to a supporter without an auxiliary band or adjustment band.

Specifically, the supporter 2 provided with the core part 65 is made of a continuous belt-like fabric among the waist supporters that are worn around the waist of the wearer, and a predetermined range in the middle in the longitudinal direction. is a back part 18 that comes into contact with the back surface of the waist, and this back part 18 has a substantially bag-like structure. A core portion 65 is housed inside the back portion 18 having a substantially bag-like structure (see FIGS. 15 and 16).

The core portion 65 is made of a plate-like material that does not have elasticity, specifically, a relatively hard thin plate material that can be bent by human force but difficult to bend, for example, made of synthetic resin. It is composed of a panel, etc., and has a shape that corresponds to and can be accommodated in the back section 18 of the supporter 2, which has a substantially trapezoidal and substantially bag-like structure. By housing this core portion 65 inside the back portion 18, it is possible to suppress excessive deformation of the back portion 18 in the worn state.

Moreover, the core part 65 is provided with a pair of notches 66 cut out in a substantially linear shape from both the left and right sides at the middle part in the vertical direction (see FIG. 17). This notch 66 makes it easy for the left and right end portions sandwiching the notch 66 to bend with respect to the central portion of the core. In addition, by separating the upper and lower portions of the core portion 65 with a portion remaining at the notch portion 66, the relative bending and twisting of the upper portion with respect to the lower portion is limited to the deformable range of the thin plate material forming the core portion 65. It will be allowed.

As a result, the back part 18 maintains its overall shape with the core part 65, and when the whole supporter is wrapped around the waist part, the back part 18 and the core part 65 come into contact with the waist part, and the whole core part 65 curves vertically and horizontally. (see FIGS. 18 and 19), or the upper or lower part of the core 65 is twisted to change direction with respect to the other (lower or upper) part of the core (see FIG. 20), and the back 18 can be made to flexibly respond to changes in the shape of the back surface of the waist region, and can be brought into close contact with the shape of the back surface of the waist region.

By making the shape of the back part 18 follow the shape of the back surface of the lumbar region in this manner, the back part 18 can be properly brought into close contact with the back surface of the wearer's lumbar region to reliably support the entire lumbar vertebrae, and the burden on the lumbar region can be suppressed as a supporter.

Further, like the pressing core part 60 in the first embodiment, the core part 65 has a shape in which a recess part 67 is provided at the center of the upper end part and the lower end part, as well as left and right notch parts 66, as shown in FIG. It is said that As a result, even if the core part 65 is curved while being worn, the centers of the upper and lower ends of the core part 65, which are relatively recessed from other parts, can be easily worn by the wearer, as in the case where no recess is provided. A situation in which local pressure stimulation is applied to the skin on the back side of the spine can be avoided, and the wearer does not feel any pain.

Although the core part 65 is housed inside the back part 18 which has a substantially bag-like structure, the structure is not limited to this. Alternatively, it may be arranged in a state where it is completely exposed, so that excessive deformation of the back part can be suppressed in the same manner as described above.
