Description

The present invention relates to a waist belt that assists the oblique muscles or tightens the pelvis.

The waist belt is fastened to the user's waist to relieve the pain caused by low back pain. Patent Document 1 discloses a main body belt (a main body part for protecting a backache) in which the left and right end portions of the main body belt are wound around a user's waist and can be disconnected, and an auxiliary belt which is attached to the main body belt and tightens the user's waist (fixing auxiliary belt). ) And a waist belt (back pain protection band) consisting of The main body belt can be disconnected by hook-and-loop fasteners provided at the left and right ends. The main body belt and the auxiliary belt are detachable with hook-and-loop fasteners provided at the left and right central portions (central portion) and the left end portion and the right end portion (predecessor portion), respectively (Patent Document 1 [Claim 1]).

The waist belt disclosed in Patent Document 1 has an advantage that an unnecessary auxiliary belt can be removed to use only the main body belt while using a main body belt and an auxiliary belt together, for example, when driving a vehicle or improving symptoms. On the contrary, the waist belt disclosed in Patent Document 1 uses only the main body belt as a normal state, but when there is a possibility of back pain or severe back pain, an auxiliary belt with an elastic reinforcement material is used. As a result, the effect of avoiding or alleviating back pain can be obtained (Patent Document 1 [0005]).

Utility model registration No. 3086242 Publication

In the waist belt disclosed in Patent Document 1, for the purpose of tightening the waist by the body belt, an auxiliary belt is attached in parallel with the body belt and the waist is fastened transversely. In this case, the muscles around the waist can be tightened to reduce the back pain. However, for example, in the case of a backache caused by a bad posture, it cannot be alleviated by simply tightening the waist. When the posture is not good, it is necessary to lift the abdomen to reduce the burden on the lower back and to correct the pelvis by tightening it. The waist belt disclosed in Patent Document 1 cannot reduce such back pain. Then, it examined, in order to provide a waist belt which can relieve a lower back pain by lifting an abdomen and tightening a pelvis.

As a result of the study, it is composed of a main body belt that is wrapped around the user's waist and an auxiliary belt that is attached to and detached from the main body belt. The belt is a waist belt that is detachable with hook-and-loop fasteners provided on the outer and inner surfaces of the left and right central portions, the left end portion and the right end portion, and the auxiliary belt is the left end portion from the upper end portion or the lower end portion of the left and right central portion. A waist belt having a pulling direction that is inclined at the right end.

In the waist belt of the present invention, an auxiliary belt having an inclined pulling direction is attached to the main body belt wound around the waist of the user. The auxiliary belt lifts the abdomen by the pulling force along the oblique abdominal muscles when the pulling direction is inclined from the upper end of the left and right center to the left end and the right end. In addition, when the pulling direction of the auxiliary belt is tilted from the lower end of the left and right center to the left end and the right end, the auxiliary belt tightens the pelvis by the pulling force that intersects the oblique abdominal muscle.

The auxiliary belt can be attached to and detached from the main body belt by a hook-and-loop fastener.For example, by attaching the main belt to the main belt by vertically flipping the configuration in which the pulling direction is inclined from the upper end of the left and right center to the left end and the right end, It can be used as a configuration in which the pulling direction is inclined from the lower end of the central part to the left end and the right end. As described above, the auxiliary belt is one type in which the pulling direction is inclined, and can be used for two types of applications of lifting the abdomen and tightening the pelvis.

Since the auxiliary belt has a pulling direction that is inclined, it is not preferable that the main body belt as the base is displaced. Therefore, the main body belt has a configuration in which the left intermediate portion and the right intermediate portion of the left and right central portions and the left end portion and the right end portion are bound together. The main body belt with the left middle part and the right middle part constricted firmly sandwiches the user with the relatively wide left and right center parts and the left end part and the right end part, while the constricted left middle part and right middle part move the waist. The risk of obstruction is eliminated and deviation is prevented.

The main body belt has a non-stretchable surface at the left-right central portion and the left end portion and the right end portion, and a male surface or a female surface of a surface fastener is provided on the outer surface, and the left middle portion between the left-right central portion and the left end portion and the right end portion. The part and the right middle part are elastic surfaces. The left and right central portions and the left end portion and the right end portion, which are non-stretchable surfaces, are respectively applied to the waist and abdomen of the user, and the positions are fixed while being less affected by the movements of the waist and abdomen. In addition, the left intermediate portion and the right intermediate portion, which are stretchable surfaces, follow the movement of the user's waist and maintain a close contact state.

When the main body belt has a structure in which an elastic reinforcing material that is continuous from the upper end to the lower end of the left and right central portion is built in, by applying the elastic reinforcing material to the spine at the left and right center of the waist, the movement of the spine is prevented. You can restrain and relieve low back pain. One elastic reinforcement member may be built in the left-right center of the main body belt in the left-right width of the spine, or a plurality of elastic reinforcements may be built in the main-body belt in the left-right center of the main belt. .. The plurality of elastic reinforcing members each have a narrow width to prevent the waist from bending back and forth, but allow the waist to be twisted to the left and right to secure the degree of freedom of the waist.

The auxiliary belt is an isosceles triangular elastic surface having a size that fits within the width of the main body belt and is convex in one of the up and down directions, and a non-convex upper end portion or lower end portion from the left and right center portion of the elastic surface to the left end portion and Consists of a tension member laid straight on the right end, and the female surface or male surface of the surface fastener is provided on the inner surface of the left and right central parts, the left end part and the right end part, and from the upper end part to the lower end part of the left and right central part A structure (narrow width type) that incorporates a continuous elastic reinforcing material is used.

The isosceles triangular stretchable surface that fits in the width of the main body belt and is convex in one of the up and down directions tilts the main stretchable direction diagonally within the range of the main body belt. For the stretchable surface, various conventionally known stretchable fabrics can be used. The tension member stretched straight from the non-convex upper or lower end of the left and right center of the stretchable surface to the left end and the right end exerts the main pulling force in the longitudinal direction of the auxiliary belt. The tensile force is made slightly oblique by being corrected by the main expansion and contraction direction of the surface. An example of the pulling member is a rubber belt. Auxiliary belts with convex upper ends in the left and right center parts lift the abdomen with a weak pulling force along the oblique abdominal muscles, and auxiliary belts with convex lower ends in the central left and right parts with a weak pulling force intersecting the oblique abdominal muscles. Tighten the pelvis. The auxiliary belt whose upper end portion in the left-right center portion is convex can be turned upside down and used as an auxiliary belt whose lower end portion in the left-right center portion is convex. The elastic reinforcing material partially suppresses the bending of the lower back to relieve the lower back pain, or fixes one end of the pulling member along the spine.

In addition, the auxiliary belt is an isosceles triangular stretchable surface that is convex in one of the up and down directions and has a size such that the left and right center portions project from the main body belt, and a convex upper end or lower end at the left and right center portion of the stretchable surface. From the left and right end portions of the tension member which is slanted and bridged over the left and right end portions, and the female surface or the male surface of the surface fastener is provided on the inner surfaces of the left and right central portions, the left end portion and the right end portion, and A structure (wide type) in which an elastic reinforcing material continuous from the upper end to the lower end is built in may be used.

The isosceles triangular stretchable surface that is convex in one of the up and down directions and has a size such that the left and right central portions thereof project from the main body belt is inclined obliquely in the main stretchable direction exerted beyond the main body belt. For the stretchable surface, various conventionally known stretchable fabrics can be used. The tension member, which is slanted from the convex upper end portion or lower end portion of the left and right center portion of the stretchable surface to the left end portion and the right end portion, aligns the pulling force in the main stretch direction of the stretchable surface. An example of the pulling member is a rubber belt. Auxiliary belts with convex upper ends in the left and right central parts lift the abdomen with a strong pulling force along the oblique abdominal muscles, while auxiliary belts with convex lower ends in the central left and right parts use a strong pulling force that intersects the oblique abdominal muscles. Tighten the pelvis. The auxiliary belt whose upper end portion in the left-right center portion is convex can be turned upside down and used as an auxiliary belt whose lower end portion in the left-right center portion is convex. The elastic reinforcing material suppresses the bending of the waist in a wide range to relieve the backache, and fixes one end of the tension member along the spine.

The waist belt of the present invention is based on the body belt wound around the waist of the user, and the abdomen is lifted by an auxiliary belt having a pulling direction inclined from the upper end or the lower end of the left and right central parts to the left end and the right end. You can also relieve back pain by tightening the pelvis. The two-member waist belt that has been conventionally seen (Patent Document 1) does not have the effect of lifting the abdomen or tightening the pelvis simply by tightening the waist of the user in the turning direction. As a result, the waist belt of the present invention exerts an effect not seen in the past.

The main body belt having the left intermediate portion and the right intermediate portion wrapped around is prevented from slipping on the waist of the wrapped user. Further, the main body belt, which has the elastic surface only in the left middle portion and the right middle portion, is prevented from being displaced with respect to the waist even when the user's waist moves. These allow the auxiliary belt to exert a tensile force inclined with respect to the main body belt when the main body belt is stably worn by the user, and bring about an effect that the pulling direction does not change midway.

A narrow-width or wide-width auxiliary belt in which a tension member is stretched straight or inclined on an isosceles triangular stretchable surface is inclined by the balance between the stretchable direction of the stretchable surface and the pulling direction of the pulling member. By changing the tension of the main body belt and attaching it by exchanging it with the main body belt, it is possible to provide a degree of difference in lifting the abdomen and tightening the pelvis. This brings about the effect that the abdominal lifting and the pelvic tightening can be adjusted by adjusting the auxiliary belt.

Hereinafter, modes for carrying out the present invention will be described with reference to the drawings. For convenience, the waist belt 1, the main body belt 2, the narrow width type auxiliary belt 3 and the wide side auxiliary belt 4 are shown and described with the outer side as the front side and the inner side as the back side (FIGS. 1 to 5 and 9). And FIG. 10), when the waist belt 1 is worn by the user 5, the side on which the outer surface of the left and right central portion can be seen is the back side, and the side on which the left end portion and the right end portion are overlapped is the front side with respect to the user 5. Be on the side.

The waist belt 1 of the present invention is, for example, as shown in FIG. 1, a main body belt 2 that is worn around a waist 51 of a user 5 (see FIG. 6 below) and a narrow belt that is detachably attached to the main body belt 2. It is composed of the width type auxiliary belt 3. The narrow type auxiliary belt 3 is detachable from the main body belt 2, and as described later, it may be turned upside down and attached to the main body belt 2 (see FIG. 7 below), or another wide type auxiliary belt 4 may be attached to the main body. It can be attached to the belt 2 (see FIGS. 11 and 12 below).

As shown in FIGS. 2 and 3, the main body belt 2 of this example has an outer shape in which the left middle portion and the right middle portion are relatively narrowed as compared with the left and right central portions and the left end portion and the right end portion (see FIG. 2). (See arrows facing each other in the middle), and is entirely composed of a stretchable surface (stretchable fabric or stretchable knitted fabric). In the left and right central portions, elastic reinforcements (synthetic resin plate, for example, polyethylene plate) 22 are built in three rows of pockets formed by four rows of sewing lines, and the main body side of the surface fastener is on the outside of the central pocket. A central female surface 21 is provided.

The left end and the right end are asymmetrical and the right end is slightly shorter than the left end, but the main surface female surface 23 of the surface fastener is on the outer surface and the main body non-slip surface (high friction material or high friction surface) on the inner surface. The structure provided with the knitted fabric) 24 is the same. The body-side female surfaces 23 at the left end portion and the right end portion are attached with end pads 25 that are non-stretchable surfaces having a pad-side male surface 251 on the inner surface and a pad-side female surface 252 of a surface fastener on the outer surface. The end pad 25 projecting from the right end is formed on the female surface 23 on the main body side at the left end or the outer surface of the end pad 25 attached to the left end when the main body belt 2 is wound around the waist 51 of the user 5. The pad side female surface 252 is engaged with the pad side male surface 251 of the inner surface protruding from the right end, and the body belt 2 is attached to the waist 51 of the user 4.

The end pads 25 are attachable/detachable to/from the main body side female surfaces 23 of the left end portion and the right end portion of the main body belt 2, and the mounting positions of the left end portion and the right end portion with respect to the main body side female surface 23 can be adjusted. The narrow-width auxiliary belt 3 has an auxiliary side end male surface 331 at the left end portion and a right end portion attached to the main body side female surface 21 at the left end portion and the right end portion of the main body belt 2, or an end attached to the left end portion and the right end portion. The pad side female surface 252 of the partial pad 25 is engaged. From this, the adjustment of the mounting position of the end pad 25 also has the meaning of adjusting the range in which the left end portion and the right end portion of the narrow width type auxiliary belt 3 can be engaged.

Further, the end pad 25 forms a non-stretchable surface on the left end portion and the right end portion of the main body belt 2 formed of a stretchable surface. When the body belt 2 is worn on the waist 51 of the user 5, the left end pad 25 and the right end pad 25 overlap the non-stretchable surface to restrain the abdomen 52 of the user 5. However, if the end pad 25 is removed from the left end of the body belt 2, the flexibility of the abdomen 52 of the user 5 is increased when the body belt 2 is worn on the waist 51 of the user 5 (see FIG. 8 below). ..

As shown in FIGS. 4 and 5, the narrow width auxiliary belt 3 is a stretchable surface (stretchable cloth) that is a flat isosceles triangle having a width (height in the vertical direction) that fits in the left and right center portions of the main body belt 2. Or stretchable mesh). The narrow width auxiliary belt 3 of this example is provided with a flexible case 31 composed of non-stretchable surfaces (synthetic leather) sandwiching the stretchable surfaces from inside and outside in the left and right central portions. The flexible case 31 contains an elastic reinforcing material (synthetic resin plate, eg, polyethylene plate) 32. Further, the flexible case 31 is provided with the auxiliary side central male surface 311 of the surface fastener on the inner surface.

The narrow width auxiliary belt 3 of this example has non-stretchable surfaces at the left end and the right end to form the end flaps 33, and the auxiliary side end male surface 331 of the surface fastener on the inner surface. In the narrow width auxiliary belt 3 of this example, the rubber belt 34 is bridged between the flexible case 31 and the left end portion and the right end portion along the base of the isosceles triangle in a downwardly convex posture. There is. The rubber belt 34 may be sewn on the inner surface or the outer surface of the narrow width type auxiliary belt 3 so as not to be displaced, or may be incorporated by being sandwiched between the stretchable surfaces forming the narrow width type auxiliary belt 3.

Since the narrow-width auxiliary belt 3 of the present example is an isosceles triangle as a whole, even if the rubber belts 3 are aligned on a straight line, the pulling direction (white arrow in FIG. 5) is inclined as a whole. Since the narrow width type auxiliary belt 3 is detachable from the main body belt 2 and can be turned upside down and attached to the main body belt 2, the pulling direction can be reversed upside down or the left and right pulling directions can be shifted. In addition, it is possible to add strength to the left and right pulling forces.

The narrow type auxiliary belt 3 includes an auxiliary-side central male surface 311 and auxiliary-side end male surfaces 331 at left and right ends, respectively, and a main-body-side central female surface 21 of the main body belt 2 and left-side and right-side main bodies. The side female surface 23 or the pad side female surface 252 of the end pad 25 is engaged at three points and attached to the main body belt 2. Here, the narrow-width auxiliary belt 3 has a flat isosceles triangle shape, and since the left and right rubber belts 34 are aligned on the same line, the pulling direction as a whole is oblique, so that either the upper side or the lower side. The utility changes depending on whether it is attached to the body belt 2 in a convex posture.

As shown in FIG. 6, the waist belt 1 in which the narrow type auxiliary belt 3 having a downwardly convex posture (the postures of FIGS. 4 and 5) is attached to the main body belt 2 has a narrowing direction of the narrow type auxiliary belt 3. Tighten the pelvis by tilting the (white arrow) in the direction that connects the side and the buttocks. Further, as shown in FIG. 7, the waist belt 1 in which the narrow type auxiliary belt 3 having an upwardly convex posture (upside down posture in FIGS. 4 and 5) is attached to the main body belt 2 is a narrow type auxiliary belt. The pulling direction (white arrow) of 3 tilts in the direction connecting the side and the spine, and assists the abdominal muscles to lift the abdomen.

In addition, as shown in FIG. 8, the waist belt 1 of the present embodiment may be used in such a manner that the narrow type auxiliary belt 3 is removed and only the main body belt 2 is wrapped around the waist 51 of the user 5. In this case, since there is no pulling force by the narrow width auxiliary belt 3, the pelvis is tightened and the abdomen is lifted gently. Furthermore, when the end pad 25 is removed from the left end of the main body belt 2 in addition to the narrow width auxiliary belt 3, pressure on the abdomen 52 due to overlapping the end pad 25 is eliminated, and the waist belt 1 is used more gently. The waist 51 of the worker 5 can be tightened.

As shown in FIGS. 9 and 10, the wide auxiliary belt 4 has an elastic surface (elastic cloth or elastic mesh) that is an isosceles triangle having a width (height in the vertical direction) protruding from the main body belt 2. Composed of. The wide width type auxiliary belt 4 of this example is provided with a flexible case 41 composed of non-stretchable surfaces (synthetic leather) sandwiching the stretchable surface from inside and outside in the left and right central portions. The flexible case 41 contains an elastic reinforcing material (synthetic resin plate, for example, polypropylene plate) 42. The flexible case 41 has an inner surface covered with an auxiliary-side non-slip surface (high-friction cloth or high-friction knitted fabric) 45 that covers the exposed outer surface up to the end flaps 43 at the left end and the right end. .. The flexible case 41 is provided with the auxiliary-side central male surface 411 on the lower half of the inner surface.

The wide auxiliary belt 4 of this example has non-stretchable surfaces at the left end and the right end to form the end flaps 43, and the auxiliary side end male surface 431 of the surface fastener on the inner surface. The auxiliary-side central male surface 411 and the auxiliary-side end male surface 431 are arranged substantially on the same line, and the wide auxiliary belt 4 attached to the main body belt 2 largely protrudes upward from the main body belt 2 (see below). See 11). The wide type auxiliary belt 4 of this example has a convex upward posture, and a rubber belt 44 is bridged between the flexible case 41 and the left end portion and the right end portion along each of the left and right hypotenuses of the isosceles triangle. .. The rubber belt 44 is sewn on the outer surface of the wide auxiliary belt 4 so as not to be displaced.

As shown in FIGS. 11 and 12, the waist belt 1 in which the wide type auxiliary belt 4 having the upward convex posture (the postures of FIGS. 9 and 10) is attached to the main body belt 2 is pulled by the wide type auxiliary belt 4. The direction (white arrow) is tilted in the direction connecting the side and the spine, and the abdomen is lifted by the pulling force along the abdominal oblique muscle. Unlike the narrow width type auxiliary belt 3, the wide width type auxiliary belt 4 has a strong pulling force, and since the pulling force is exerted along the oblique muscle of the abdomen, the abdomen is firmly lifted. Then, the flexible case 41 containing the elastic reinforcing member 42 is placed on the spine to suppress the bending of the waist 51.

Further, the wide type auxiliary belt 4 widely covers the back by the bottom side which is attached to the main body belt 2 and is restrained by the main body belt 2 and the oblique side which bridges the rubber belt 44, and moreover, the non-slip surface 45 which is the inner surface is almost the main body. It projects from the belt 2 and faces the back. Therefore, the user 5 restrains the movement of the waist 51 in a wide range by the wide auxiliary belt 4 and relieves the back pain. The wide type auxiliary belt 4 restrains the waist 51 of the user 5 and thus is not turned upside down. However, since the engaging position of the hook-and-loop fastener can be adjusted vertically or horizontally, the waist 51 is restrained. You can adjust the condition.
