Description

The present invention relates to a waist supporter that strongly tightens and holds the waist circumference.

Generally, various supporters are used to protect the skin, joints, tendons, cartilage, and the muscles around them. There are various types of supporters such as tape-shaped and cloth depending on the material form, and there are various types such as for arms, knees, and waist depending on the place of use. The waist supporter protects the skeleton, muscles, and nerves around the back, buttocks, and hips, and is designed to look good when worn and to be easy to wear on the body. In order to improve the wearing feeling of the waist supporter as a shape corresponding to the mounting part, for example, the vertical width at the center of the waist supporter is increased and the vertical width in the tip direction of the waist supporter is reduced. Will be done.

The skin around the waist, joints, tendons, cartilage, and the muscles around it have large parts and small movements. For example, around the joint, the morphology of the part changes greatly depending on the range of motion. In addition, the morphology of the skin and muscles of the abdomen changes significantly due to breathing. Therefore, the elastic part of the waist supporter protects the part with large movement, while the non-expandable part of the waist supporter protects the part with small movement, which limits the movement of joints and muscles and protects it. By devising the selection of elastic / non-stretchable materials for each member of the waist supporter, it is possible to maintain and improve the wearing feeling.

Patent Document 1 describes a waist supporter that fits the wearer's waist and sufficiently presses the wearer's back to improve the wearing feeling. The waist supporter 100 has a substantially V-shaped band shape. A first pressing band portion 30 composed of a body, fixed at two points on one side of the backrest, and a V-shaped apex is arranged between the one side and the center of the backrest, and one end. 41 is fixed to the V-shaped apex 33 of the first pressing band portion 30, and the hook 43 of the surface fastener disposed at the other end 42 is engaged with the loop 21 of the winding portion 20 on the right side. It consists of a band portion 40 and a substantially V-shaped strip, and is fixed at two points on the other side of the backrest, and a V-shaped apex is arranged between the other side and the center of the backrest. The second pressing band portion 50 and one end 61 are fixed to the V-shaped apex 53 of the second pressing band portion 50, and the hook 63 of the surface fastener disposed at the other end 62 is the winding portion 20 on the left side. A waist supporter comprising a second tension band portion 60 engaged to the loop 21 is described.

Patent Document 2 is a waist belt 1 that absorbs the difference in the circumference of the waist and does not impair the function of tightening the waist even if the user moves, and the left inner tightening belt 43 is extended from the left main body belt 2 to the right. The left folding ring 33 of the main body belt 3 folds back, the right inner tightening belt 53 extends from the right main body belt 3 and folds back at the right folding ring 23 of the left main body belt 2, and the left auxiliary tightening belt 6 is the right main body belt 3. The right sub-tightening belt 7 extends to the right from the left main body belt 2, and the left outer tightening belt 44 is connected to the left sub-tightening belt 6 and attached to and detached from the left main body belt 2. Folded back from the fixing ring 45, folded back from the left connecting ring 433 of the left inner tightening belt 43 and connected to the left main body belt 2, the right outer tightening belt 54 is connected to the right sub-tightening belt 7, and the right main body belt 3 A waist belt 1 is described, which is folded back from the right fixing ring 55 attached to and detached from the right side, folded back from the right connecting ring 533 of the right inner tightening ring 53, and connected to the right main body belt 3.

When the waist supporter 100 described in Patent Document 1 is worn, first, the winding portion 20 is engaged by engaging with the engagement area 22 by the hook 24 of the hook-and-loop fastener, and then secondly, the second. The tension band portion 40 of 1 and the second tension band portion 60 are pulled out and further tightened to engage them. Therefore, as a matter of course, when the second engagement, that is, the tension band portion is pulled out and engaged, rather than the diameter of the waist supporter 20 when the first engagement, that is, the winding portion 20 is engaged. The diameter of the waist supporter 20 is smaller.

However, in the waist supporter 100 described in Patent Document 1, the winding portion 20 and the back support portion 10 are sewn together, and the winding portion 20 on the right side and the winding portion 20 on the left side are integrated. Therefore, by maintaining the shape of the waist supporter 100 itself, the force for further tightening is weakened when the first tension band portion 40 and the second tension band portion 60 are pulled out. On the back of the user, the left winding portion 20 and the right winding portion 20 try to move in a direction close to each other, but the movement is hindered by the back rest portion 10.

On the other hand, in the waist belt 1 described in Patent Document 2, the left inner tightening belt 43 and the right inner tightening belt 53 are arranged diagonally asymmetrically and are pulled out diagonally, so that a pair of left and right waist pads move diagonally. There is a possibility that the force will not be applied evenly to the left and right and the force to support the waist will be uneven (Fig. 1). Further, since the left sub-tightening belt 6 and the right sub-tightening belt 7 are elastic, the tightening force of the left sub-tightening belt and the right sub-tightening belt is reduced as compared with the non-stretchable material. Therefore, large tightening is particularly difficult. The left main body belt 2, the right main body belt 3, the left inner tightening belt 43, the left outer tightening belt 44, the right inner tightening belt 53, and the right outer tightening belt 54 are non-stretchable materials. Therefore, after the female surface 242 of the hook-and-loop fastener provided on the outer surface of the left main body belt 2 is engaged with the male surface 341 of the hook-and-loop fastener provided on the inner surface of the left end 31 of the right main body belt 3, especially the lower portion of the waist belt 1. In, it is difficult to make the diameter of the waist belt 1 larger than the meshed diameter, and when the user breathes, a feeling of oppression occurs. Further, while the left sub-tightening belt 6 and the right sub-tightening belt 7 are elastic, the left inner tightening belt 43, the left outer tightening belt 44, the right inner tightening belt 53, and the right outer tightening belt 43. Since the attached belt 54 is a non-stretchable material, a non-uniform tightening force is generated above and below the waist belt 1.

Further, in Patent Document 2, when the left inner tightening belt 43, the left outer tightening belt 44, the right inner tightening belt 53, the right outer tightening belt 54, etc. are used for diagonal pulling, an inclined tightening force is obtained. The diameter of the waist supporter can be easily reduced when the connecting ring is engaged in the second position, but to pull the left and right sides of the waist supporter in the winding direction (engagement ring). If you try to tighten it strongly through the belt, the lumbar region will move, and if you move the lumbar region so that it overlaps, the lumbar region will not be stable.) It was difficult to apply sufficient pressure to the surface to be used. Further, there is a problem that the position of the engaging ring for locking the tightening belt is in contact with the skin (waist).

Therefore, an object of the present invention is for the waist where a tightening force can be exerted strongly around the left and right hip pads of the separated structure, and a tightening load can be applied by uniformly tightening the entire waist circumference. Provide supporters.

The present invention is a waist supporter provided with a waist support, a waist belt extending from the waist support and engaging with each other, and a tightening belt for tightening the waist support and the waist belt. While separating the hip pad, a central connecting band that connects the left hip pad and the right hip pad and a first adjusting band that adjusts the length and elastic force of the central connecting band are provided, and the first adjustment band is provided. The left and right hip pads connected to the adjustment band 1 are provided , and the left hip pad and the right hip pad are tightened at positions apart from the left and right hip positions, and the central connecting band is The distance between the left and right hip pads is adjusted so that the left and right hip pads are located at such a distant position, but the central connecting band is concave or U-shaped even if the left and right hip pads are close to each other. It is characterized in that it is folded into a shape and does not cause an overlap between the left hip pad and the right hip pad . The central connecting band may be a single piece, but is preferably concave, U-shaped, or has a foldable structure.
According to the present invention, when the left and right tightening belts are pulled out by hand, the first adjusting band is pulled to the left and right, thereby adjusting the length and elastic force of the first adjusting band to connect the center. Since the band adjusts the distance between the left and right hip pads (because it is concavely deformed to the outside or folds outward), the left and right hip pads are brought closer to each other to tighten the waist. Then, since the tightening force can be exerted around the left and right hip pads, the hip pads are not displaced and an effective tightening force can be obtained. That is, a sufficient pressing force is generated on the back of the user, particularly on the left and right surfaces (left and right lumbar regions) centered on the lumbar spine.

In the present invention, when the left and right tightening belts are pulled out, the first adjusting band is pulled to the left and right, whereby the first adjusting band is extended and the extension force of the central connecting band is weakened. Alternatively, the central connecting band is folded so as to adjust the distance between the left and right hip pads.
According to the present invention, it is preferable that both the central connecting band and the first adjusting band are arranged on the outside, but the central connecting band is left and right due to the extension of the first adjusting band or the like. Since the distance between the waist pads is adjusted, the first adjustment band may be concavely deformed outward or folded outward, so an engagement ring or the like should be placed where it comes into contact with the skin (lumbar). There is no contact, and a sufficiently strong pressing force is generated especially on the surface centered on the lumbar spine.

In the present invention, the left and right tightening belts are pulled out to the left and right via the first adjustment band, and a second adjustment band is provided on the left and right tightening belts, so that the second adjustment band is provided. It is characterized by being pulled out through a belt. It is preferable that the left and right tightening belts are provided with left and right folded portions that are folded back via the engagement ring, and are provided with the second adjusting band. The second adjusting band adjusts the length of the central connecting band (the amount of expansion and contraction) together with the length of the first adjusting band (the amount of expansion and contraction).
According to the present invention, the distance between the left and right hip pads by the central connecting band is adjusted not only by the first adjusting band but also by the second adjusting band, so that uniform tightening is performed. It is possible to evenly apply the tightening load to the entire waist circumference.

In the present invention, the first adjusting band is connected to a belt so as to cover above the central connecting band, and includes a portion crossed with each other, and the left and right tightening belts are provided with the left and right tightening belts. It is characterized in that it is pulled out in the pull-out direction via an engagement ring.
According to the present invention, it is possible to obtain a tightening force of the waist portion centering on the left and right waist contact portions of the left and right tightening belts. That is, by pulling out the left and right tightening belts in parallel and in the center along the belt width, a uniform tightening force can be obtained along the belt width and in the center even on the outer circumference of the waist, the flanks, and the anterior abdomen. Become.

In the present invention, the stretching force of the central connecting band and the stretching force of the first adjusting band correspond to each other to expand or contract, or the length of the first adjusting band relative to the length of the central connecting band. It is characterized in that the distance between the left and right hip pads is adjusted so that the left and right hip pads do not overlap with each other. Further, it is preferable that both the central connecting band and the first adjusting band are arranged on the outside of the left and right hip pads so that the left and right hip pads do not overlap.
According to the present invention, a tightening force of the waist portion centered on the left and right hip portions can be obtained. That is, by pulling out the left and right tightening belts, if the left and right hip pads overlap, the symmetrical tightening force from the left and right around the spinal cord will not be applied (pressing pressure as one part of the spinal cord). It only takes). However, according to the present invention, since they do not overlap with each other, the tightening force can be exerted around the left and right hip pads.

According to the present invention, the length and elastic force of the central connecting band that connects the left hip pad and the right hip pad while separating the left hip pad and the right hip pad, and the central connecting band. Since the first adjusting band to be adjusted is provided and the left and right tightening belts connected to the first adjusting band are provided, the tightening force can be exerted centering on the left and right hip pads. Therefore, there is no displacement of the hip rest (the overlap of the hip rest does not occur), and an effective tightening force can be obtained.
Further, by providing the second adjusting band on the left and right tightening belts, the second adjusting band has the length of the first adjusting band (the amount of expansion and contraction) and the length of the central connecting band. (Amount of expansion and contraction) can be adjusted, and the distance between the left and right hip pads by the central connecting band can be adjusted not only by the first adjustment band but also by the second adjustment band. Since it is performed, it is possible to perform uniform tightening and apply a tightening load to the entire waist circumference.

(Embodiment)
FIG. 1 is a front view of the waist supporter 1 of the present embodiment, and is a view shown from the front side in a lateral direction in the length direction. FIG. 2 is a rear view of the waist supporter 1, and is a view showing the waist supporter of FIG. 1 from the back side, which is a surface in close contact with the body. FIG. 3 is a perspective view of the waist supporter 1 of the present embodiment, and shows a case where the waist supporter 1 of FIG. 1 is viewed from below to above. 4 and 5 are reference perspective views for assisting the explanation with reference to FIG. FIG. 4 shows a case where the waist supporter 1 of FIG. 1 is viewed from the lower left side to the upper right side, and FIG. 5 is a perspective view of the waist supporter 1 viewed from the back side.

In the present invention, when the waist supporter 1 is attached, the side that does not come into close contact with the body (the surface that can be seen from the outside) is referred to as the "front side" of the waist supporter 1 (FIGS. 1, 3 and 4). The side in close contact with the body (the surface that cannot be seen from the outside) is called the "back side" of the waist supporter 1 (FIGS. 2 and 5).

The waist supporter 1 of the present embodiment has elasticity in the circumferential direction, and as shown in FIGS. 1 and 2, the waist supporter 1 is a pair of left and right waist support portions 2 that are in contact with the waist portion of the user. A pair of left and right waist belts 3 that are integrally connected to the waist support 2 and wound around the waist side, a central connecting band 4 that connects the pair of left and right waist pads 2 to support the lumbar spine, and a waist belt. A pair of left and right tightening belts 5 that are wound from the outside of 3 to assist the waist belt 3 and one end are fixed to the waist contact portion 2 and the other end is connected to the tightening belt 5 via an engagement ring 6. It has a left connecting band 7 and a right connecting band 8.

In the present invention, the "left-right pair" means that the left-right line is symmetrical with respect to the center line A of the waist supporter 1 shown in FIGS. 1 and 2. In the present invention, the "left side" means the left side on the front side of the waist supporter 1 shown in FIG. 1, and the "right side" means the right side on the front side of the waist supporter 1 shown in FIG. Means that

The waist supporter 1 of the present embodiment is a supporter for protecting and / or strengthening the skeleton, muscles, and nerves around the back, hips, and waist, and the material of the fabric is rayon, polyester, or the like. It is composed of synthetic fibers such as nylon and / or acrylic, and / or rubbery fibers, and / or a combination thereof, and these fibers are woven into a multilayer structure.

The waist support portion 2 and the waist belt 3 have a series of integrated configurations in which a single piece of breathable elastic material is used as the fabric, and are bordered by the outer edge portion 9 and the fastening means 10 and the like. Some non-stretchable materials are sewn on top of each other. The engagement means 10 (for example, the female portion of the hook-and-loop fastener) is sewn on the waist belt 3, and the side on which the engagement means 10 is not sewn is the right waist contact portion 2 (FIG. 1).

When the waist supporter 1 is viewed from the front side, the waist support portion 2 has a non-stretchable locking portion 11 that engages the left and right connecting bands 7 and 8 as a material of the elastic material of the waist supporter 1. Is sewn on (Fig. 1). The waist contact portion 2 has a support portion 2a on the side closer to the center line A than the locking portion 11, that is, the side connected to the central connecting band 4 with the locking portion 11 as a boundary, and the center line A rather than the locking portion 11. The side far from the waist, that is, the side connected to the waist belt portion 3 is referred to as a transition portion 2b (FIG. 1).

The vertical widths of the support portion 2a and the transition portion 2b are different, and the vertical width of the support portion 2a is wider than that of the waist belt 3 and has an approximately constant vertical width, which is sufficient to support the lumbar spine and the thoracolumbar fascia. Have. The vertical width of the support portion 2a is not particularly limited, but is preferably 10 cm to 20 cm, more preferably 12 cm to 17 cm for adults. The width of the support portion 2a is smaller than the vertical width of the support portion 2a, and the width of the support portion 2a is preferably 5 cm to 15 cm, more preferably 8 cm to 12 cm for an adult, but is not limited thereto. The transition portion 2b is located between the support portion 2a and the waist belt 3, and the vertical width gradually narrows as the support portion 2a approaches the waist belt 3 (FIGS. 1 and 2). By using the transition portion 2b as an elastic material, an elastic force (stretching recovery force) in the direction opposite to the winding direction is generated when the waist supporter 1 is attached as described later, and the transition portion 2b is tightened with the waist belt 3. Improves the fit when wearing.

The support portion 2a has a pocket-shaped storage portion 12 having an opening portion 12a at the upper portion on the back side of the waist supporter 1 (FIGS. 2 and 5). A cushion material is inserted into the storage portion 12 to disperse the pressure on the waist portion due to the tightening of the waist supporter 1 and improve the wearing feeling.

The waist belt 3 is wound around the waist from the back to the abdomen, and presses and supports the waist from the outside, and supports, for example, the compound oblique muscle, the rectus abdominis muscle, and the transverse abdominal muscle. The vertical width of the waist belt 3 is not particularly limited, but is preferably 5 cm to 10 cm for adults. The width of the waist belt 3 is preferably changed as appropriate according to the waist circumference of the user (FIGS. 1 and 2).

On the front side of the waist belt 3, a fastening means 10 such as a female portion of a hook-and-loop fastener is sewn from above the elastic material (FIG. 1). Further, on the back side of the waist belt 3, a fastening means 13 such as a male part of a hook-and-loop fastener is sewn on one of the pair of left and right waist belts from above the elastic material, and the pair of left and right waist belts 3 When they are overlapped with each other, they are in a detachable engagement state (Fig. 2). For example, as shown in FIG. 2, the male portion 13 of the hook-and-loop fastener is arranged on the back side of one waist belt 3, and the female portion 10 of the hook-and-loop fastener arranged on the front side of the other waist belt 3 shown in FIG. It is overlapped and entwined.

The details of the tightening belt (second adjusting band) 5 will be described with reference to FIG. The tightening belt 5 which is the second adjusting band is composed of a first tightening belt 5a made of a non-stretchable material and a second tightening belt 5b made of an elastic material, and the first tightening belt 5a has one end 50a thereof. It is connected to the engagement means 10 sewn on the front side of the waist belt 3, passes through the engagement ring 6, and is folded back (FIG. 3). A fastening means 10 such as a male portion of a hook-and-loop fastener is sewn on the back side of the other end of the first tightening belt 5a (not shown), and the folded first tightening belt 5a engages the waist belt 3. It is configured to be attached to the landing means 10. For example, when the waist supporter 1 is not attached, the engaging means 10 of the right tightening belt 5a is engaged with the engaging means 10 of the right waist belt 3, and when the waist supporter 1 is attached, the first on the right side. The engaging means of the tightening belt 5a is attached to the engaging means 10 of the left waist belt 3. The second tightening belt 5b is shorter than the first tightening belt 5a, and one end 50b of the second tightening belt 5b is connected to the fastening means 10 sewn on the front side of the waist belt 3 to connect the second tightening belt. The other end 51b of 5b is sewn to the back side of the first tightening belt 5a. One end 50a of the first tightening belt 5a and one end 50b of the second tightening belt 5b are connected to the end of the engaging means 10 so as to overlap each other.

From one end 50a of the first tightening belt 5a (the part connected to the engaging means sewn on the front side of the waist belt 3), the other end 51b of the second tightening belt 5b is sewn to the first tightening belt 5a. The length to the formed portion 51a is configured to be longer than the length from one end 50b to the other end 51b of the second tightening belt 5b (FIG. 3).

As a result, when the first tightening belt 5a is wound around the waist and is engaged with the waist belt 3, the second elastic material is in the direction opposite to the direction wound by the first tightening belt 5a. The tightening belt 5b of the above causes an elastic force (stretching recovery force). This reverse elastic force (extension recovery force) creates an elastic force (extension recovery force) in the force that tightens the hip circumference, which improves the wearing feeling and enables compression by the lumbar spine 2 toward the lumbar spine and spine. Become. Further, by adjusting the tensile force when the first tightening belt 5a is wound, the reverse tensile force / elastic force (stretching recovery force) of the second tightening belt 5b is also adjusted, so that the waist circumference can be adjusted. The tightening force can be adjusted. Further, since the transition portion 2b is also made of an elastic material, when the waist supporter 1 is attached, the transition portion 2b also has an elastic force (extension recovery force) in the direction opposite to the direction wound by the first tightening belt 5a. ) Can be generated, and the wearing feeling when tightened with the waist belt 3 is improved.

A non-stretchable material such as a metal member or a general-purpose plastic is used for the engagement ring 6, and the general-purpose plastic is suitable from the viewpoint of wearing comfort. This is because the tightening belt is strongly pulled out through the engaging ring 5.

The connecting band (first adjusting band) is a central connecting band 4 sewn and connected to a locking material 13 arranged on a pair of left and right hip pads 2, and one ends 70a and 70b are right hip pads. The left connecting band 7 connected to the locking portion 11 of 2a and the other ends 71a and 71b engage with the left engaging ring 6, and the one ends 80a and 80b are connected to the locking portion 11 of the left hip contact portion 2a. The other ends 81a and 81b are connected to each other and consist of a right connecting band 8 that engages with the right engaging ring 6 (FIGS. 4 to 6). The central connecting band 4 is made of an elastic material, and the left connecting band 7 and the right connecting band 8 are made of a non-stretchable material, but both of them may be made of an elastic material and their elastic force may be adjusted.

The left connecting band 7 and the right connecting band 8 have a symmetrical shape so that a more uniform tensile force is generated when the belt is wound around the tightening belt 5. For example, as shown in this embodiment, when the left connecting band 7 has a small shape and the left connecting band 7 has a small shape, the right connecting band 8 has a large shape. The small left connecting band 7 is a left upper band 7a connected at the upper 70a of the locking portion 11 arranged on the right hip contact portion 2a and a lower left band 7b connected at the lower 70b of the locking portion 11. Similarly, the right connecting band 8 which is divided into two and has a large shape is also connected to the upper right band 8a connected by the upper 80a of the locking portion 11 arranged on the left hip portion 2a and the lower 80b of the locking portion 11. It is divided into two parts, the lower right band 8b, which is connected by (Figs. 1, 3 and 4).

When the upper left band 7a is overlapped above the upper right band 8a as in this embodiment, it is preferable that the lower left band 7b is overlapped below the lower right band 8b (FIGS. 1, 3 and 4). If the upper left band 7a is overlapped below the upper right band 8a, the lower left band 7b is overlapped above the lower right band 8b. With such a configuration, the left connecting band 7 and the right connecting band 8 interfere with each other when the pair of left and right tightening belts 5 are not engaged or when they are pulled away from the body. By meeting each other, the movement of the tightening belt 5, the left connecting band 7, and the right connecting band 8 in the direction away from the body is suppressed, and a compact configuration is formed. For example, if the upper left band 7a is overlapped on the upper right band 8a and the lower left band 7a is overlapped under the lower right band 8a as in this embodiment, the upper right band 8a is separated from the body by the upper left band 7a. The movement in the direction is restricted, and the lower left band 7b is restricted from moving away from the body by the lower right band 8b, so that both the left connecting band 7 and the right connecting band 8 are difficult to separate from the body.

(Specific example when wearing the waist supporter 1 of the present invention)
An example of wearing the waist supporter 1 will be described. First, a pair of left and right waist belts 3 are wound around the waist, and the male part 13 (FIG. 2) of the surface fastener arranged on the back side of the right waist belt 3 and the surface fastener arranged on the front side of the left waist belt 3 Is engaged with the female portion 10 (FIG. 1) of the above.

The central connecting band 4 of the elastic material and the transition portion 2b of the elastic material exert an elastic force (stretching recovery force) in the direction opposite to the winding direction (the direction in which the waist supporter 1 contracts to the original size). Since it is generated, it is configured so that an excessive tightening force is not generated even when the user breathes.

The male part (not shown) of the hook-and-loop fastener sewn on the back side of the first tightening belt 5a by winding the first tightening belt 5a from above the pair of interlocked waist belts 3, and the front side of the waist belt. It is engaged with the female part 10 (FIG. 1) of the hook-and-loop fastener arranged in.

The pair of left and right hip pads 2a are connected by the central connecting band 4 of the elastic material, but are semi-independent. Therefore, when the first tightening belt 5a is used for engagement, the pair of left and right hip support portions 2a can move in the close direction on the back of the user and can be easily tightened.

The left connecting band 7 and the right connecting band 8 have a symmetrical structure, and the upper bands 7a and 8a are connected to the upper 70a and 80a of the locking portion 11, respectively, and the lower bands 7b and 8b are locked. Since it is connected to the lower portions 70b and 80b of the portion 11, the tensile force applied to the waist contact portion 2a is dispersed, and the tensile force is generated over a wide range. Therefore, a biased tightening force is not generated, the tightening force around the waist is also dispersed, and the structure is easy for the user to wear.

When the first tightening belt 5a is wound around the waist as much as possible, the second tightening belt 5b made of the elastic material extends to the same length as the first tightening belt 5a made of the non-stretchable material and engages with the first tightening belt 5a. The ring 6 moves to the points 50a and 50b where one end of the first tightening belt 5a and the second tightening belt 5b is connected to the fastening means of the waist belt (FIG. 3).

Further, when the first tightening belt 5a is engaged, the second tightening belt 5b of the elastic material and the transition portion 2a are wound around the waist by the first tightening belt 5a (for the waist) as described above. Since the elastic force (extension recovery force) is generated in the direction in which the supporter extends laterally and in the opposite direction (the direction in which the waist supporter 1 contracts laterally), the user can easily breathe. There is. Further, since the first tightening belt 5a, the engagement ring 6, the left connecting band 7, and the right connecting band 8 are made of non-stretchable materials, the first tightening belt 5a is wound around the waist as much as possible. When the engagement ring 6 stops at the connection points 50a and 50b, the only member that can be further extended in the circumferential direction is the transition portion 2b of the stretchable material. Therefore, when the first tightening belt 5a is wound around the waist, a large tightening force can be generated.

(Second embodiment)
FIG. 6 is a front view of the waist supporter 1 when the waist belt 3 is pulled out and the pair of left and right waist support portions 2 are in contact with each other. In the second embodiment of the present invention, when the waist supporter 1 is attached, the pair of left and right waist support portions 2 are not overlapped with each other on the back of the user as shown in FIG. 6, and are more uniform. Allows for great pressure. The same points as in the first embodiment will be omitted.

FIG. 7 is a perspective view showing a detailed configuration of the waist supporter 1 of the present embodiment. In the present embodiment, the central connecting band 4, the left connecting band 7, the right connecting band 8, and the auxiliary belt 5 are configured as adjusting members for preventing the pair of left and right waist contact portions 2 from being overlapped with each other. And / or interact with each other. In the present embodiment, the case where the pair of left and right hip pads 2 are overlapped with each other on the back is referred to as “overlapping”, and the length of the overlapping portion is referred to as “overlapping length”. Further, in the present embodiment, unless otherwise specified, the "horizontal width" refers to the length in the lateral direction in FIG. 1, and is the length in a state where the waist supporter 1 is not expanded or contracted. In the case of elastic material, the original length (length when not stretched) is the width, and the maximum elongation is the maximum width length.

A case where the overlap length is <0 will be described with reference to FIG. 7. The length from one end 50a of the first auxiliary belt 5a to the turning point 52a at which the first auxiliary belt 5a is folded back by the engaging ring 6 is defined as the width X5a. By setting X5a <X4, the width X5a and the width X4 of the central connecting band 4 have an overlapping length <0. This is because the engaging ring 6 stops at one ends 50a and 50b, which are the joints between the engaging means 10 and the auxiliary belt 5, before the left and right hip contact portions 3 overlap.

There are at least four configurations for X5a <X4. The first is a configuration in which the width X4 of the central connecting band 4 is lengthened so that X5a <X4. When the central connecting band 4 is made of an elastic material, the maximum width length X4 of the central connecting band is set to MAX, and X5a <X4 is set to MAX. Second, by increasing the width of the connecting band (width X7 of the left connecting band 7 and width X8 of the right connecting band 8), the engaging ring 6 is brought closer to the engaging means 10, X5a is shortened, and X5a < It is configured as X4. Third, the engagement means 10 is brought closer to the engagement ring 6 by arranging the engagement means 10 up to the transition portion 2b or by shortening the width of the transition portion 2b and increasing the width of the waist belt 3, and X5a. Is shortened so that X5a <X4. Fourth, the width X6 of the engaging ring 6 is lengthened so that X5a <X4.

Next, a case where the overlap length <0 is set by a method other than X5a <X4 will be described with reference to FIG. 7. When the first auxiliary belt 5a is pulled out (wound when attached), the upper left band 7a is overlapped on the upper right band 8a, so that the lower 70c of one end 70a of the upper left band 7a is the upper right band. It intersects with the intermediate position 80d of 8a and interferes with each other, and acts so as not to be pulled out any further. Similarly, since the lower left band 7b is overlapped under the lower right band 8b, the intermediate position 70d of the lower left band 7b intersects with the upper 80c of one end 80b of the lower right band 8b and interferes with each other. It works so that it cannot be pulled out any further.

The length from 70c to 80d is defined as the width XR, and the length from 70d to 80c is defined as the width XL in a state where the waist supporter 1 that maintains the original length of the central connecting band 4 is not expanded and contracted. By setting X4> width XR and / or width XL with respect to the width X4 of the central connecting band 4, the overlapping length <0. Since the description of the configuration for width X4> width XR and the configuration for width X4> width XL overlap, the configuration for width X4> width XR will be described, and the same applies to width X4> width XL. The explanation is omitted.

As a configuration in which the width X4> the width XR, the width of the left and right connecting bands (the width X7 of the left connecting band 7 and the width X8 of the right connecting band 8) is lengthened to incline the upper and lower bands of the connecting band. It is conceivable that the width XR is shortened by making the width XR gentle.

As described above, in the waist supporter 1 of the present embodiment, the central connecting band 4, the left connecting band 7, the right connecting band 8, and the auxiliary belt 5 are configured as adjusting members, whereby a pair of left and right waist pads are provided. The portions 2 act so as not to overlap each other, and the left and right hip contact portions 2 enable uniform compression on the waist portion. Although the present invention has been described above, the present invention can be appropriately modified without departing from the spirit of the present invention.
