Disclosure of Invention

However, although the waist protector of patent document 1 can restrict the movement of the waist, it presses the abdomen at the same time. As the abdomen is compressed, the stomach and intestines are compressed, and the movement of the stomach and intestines is decreased, resulting in the symptoms of the backflow of gastric acid, the retention of gastric acid, the circulation of the stomach wall is not complete, and the like. Further, the kinesiology tape of patent document 2 is attached only to the waist of the human body, and therefore does not press the abdomen, but does not have a portion supporting the waist, and the feeling of fixation of the waist is poor.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a waist protector capable of restricting the movement of the waist without pressing the abdomen.

The waist protector of the present invention is a waist protector that is attached to a waist of a human body and restricts movement of the waist, the waist protector comprising: a skeleton member having an elastic restoring force; and a bonding member for bonding the frame member to the waist portion, the frame member including: a pair of longitudinal extension portions extending substantially parallel to each other with a gap therebetween so as to follow a lumbar vertebra of the waist portion when the waist portion is attached thereto; and a lateral extension portion extending in a direction intersecting a direction in which the pair of longitudinal extension portions extend, and connecting the pair of longitudinal extension portions to each other.

Preferably, the frame member further includes a lower extension portion extending downward from a lower end of the lateral extension portion.

Preferably, the frame member is formed such that the interval increases in a horn shape as it goes toward the upper end sides of the pair of longitudinally extending portions.

Preferably, the adhesive member contains a cooling component, a heating component, or a medicinal component.

Further preferably, the attaching member includes: a non-woven fabric layer for adhering the skeleton part; and an adhesive layer for adhering the nonwoven fabric layer to the waist portion.

Preferably, the attachment member has an alignment portion for aligning the waist protector along the lumbar spine when the waist protector is attached to the waist portion.

Preferably, the attachment member has a high-elongation portion that elongates to a greater extent than other portions of the attachment member in accordance with the elongation of the skin of the waist portion when the waist protector is attached to the waist portion.

Preferably, the waist protector further comprises a release paper attached to the attaching member and removed when the waist protector is attached to the waist portion,

the release paper has a non-adhesive portion protruding downward from the lower end of the adhesive member and not adhering to the adhesive member.

Detailed Description

Hereinafter, a waist protector according to an embodiment of the present invention will be described with reference to the drawings. However, the embodiments described below are merely examples, and the waist protector of the present invention is not limited to the following examples. In the present specification, the terms "upper", "lower", "left", "right", "front", and "rear" respectively mean directions in a state where the waist protector is attached to the waist of the human body, specifically, "upper" means a head side as viewed from the waist, "lower" means a foot side as viewed from the waist, "left" means a left hand side as viewed from the waist, "right" means a right hand side as viewed from the waist, "front" means an abdomen side as viewed from the waist, and "rear" means an opposite side of the abdomen as viewed from the waist.

The waist protector 1 of the present embodiment is attached to the waist W of a human body and regulates the movement of the waist W. The waist protector 1 suppresses pain in the waist W by restricting movements such as forward flexion, backward flexion, and left-right twisting of the waist W, which cause pain, or assists to stabilize the posture of the waist W, thereby reducing muscle fatigue for stabilizing the posture of the waist W and suppressing occurrence of lumbago.

As shown in fig. 1 and 2, the waist protector 1 includes: a skeleton member 2 having an elastic restoring force; and an attachment member 3 for attaching the frame member 2 to the waist portion W. The waist protector 1 further includes a release paper 4 which is attached to the attachment member 3 as desired and is removed when the waist protector 1 is attached to the waist W.

The frame member 2 is attached to the waist W by the attachment member 3, and regulates the movement of the waist W by an elastic restoring force. Here, the elastic restoring force is a force that is elastically deformed to restore to an original state when an external force is applied, for example. The movement of the waist W is not limited to physically restricting the movement of the waist W by supporting the waist W by resistance generated by the elastic restoring force of the skeletal member 2, for example, but includes a user who stimulates the skin of the waist W by the elastic restoring force of the skeletal member 2 when the user moves the waist W, and senses the movement of the waist W by the stimulation of the skin, and intentionally restricts the movement of the waist W of a larger magnitude. The waist protector 1 can restrict the movement of the waist portion W without pressing the abdomen by using the frame member 2 for restricting the movement of the waist portion W by being attached to the waist portion W by the attachment member 3.

The frame member 2 is not particularly limited as long as it can be configured to restrict the movement of the waist portion W, but in the present embodiment, as shown in fig. 1, 3, and 4, it includes: a pair of longitudinal extension portions 21, 21 extending substantially parallel to each other with a gap D therebetween so as to be along the lumbar vertebra L of the waist portion W when attached to the waist portion W; and a lateral extension portion 22 extending in a direction intersecting (substantially orthogonal in the illustrated example) the direction in which the pair of longitudinal extension portions 21, 21 extend, and connecting the pair of longitudinal extension portions 21, 21 to each other.

As shown in fig. 3 and 4, the pair of longitudinal extending portions 21, 21 are attached to both left and right sides of the lumbar vertebra L of the waist portion W so that the direction in which the pair of longitudinal extending portions 21, 21 extend is substantially parallel to the direction in which the lumbar vertebra L extends, and mainly restrict the movement of the waist portion W in the front-rear direction (for example, the forward flexion and the backward flexion of the waist portion W). As shown in the drawing, the pair of longitudinally extending portions 21, 21 are connected to each other by the laterally extending portion 22, and therefore, since the deformation of any one of the longitudinally extending portions 21 is restricted not only by the elastic restoring force of any one of the longitudinally extending portions 21 but also by the elastic restoring force of the other one of the longitudinally extending portions 21 and the laterally extending portion 22, the resistance against the waist portion W can be increased as compared with the case where the longitudinally extending portions 21 and the laterally extending portions 22 are independently arranged, and the movement of the waist portion W can be restricted more firmly. In the present embodiment, as shown in fig. 1, the pair of longitudinally extending portions 21, 21 are connected to each other by the laterally extending portion 22 on the lower end side of the pair of longitudinally extending portions 21, and the frame member 2 is formed in a substantially U shape as a whole. Therefore, the pair of longitudinal extension portions 21 and 21 are configured such that the lateral extension portion 22 is attached to the vicinity of the sacrum S and the ilium I below the lumbar vertebra L as described later, and the movement of the lumbar vertebra L with respect to the sacrum S and the ilium I can be restricted in cooperation with the lateral extension portion 22. However, as long as the pair of longitudinal extending portions 21, 21 are connected to each other by the lateral extending portion 22, the position where the pair of longitudinal extending portions 21, 21 are connected to each other by the lateral extending portion 22 is not particularly limited, and may be connected to each other in the middle region in the vertical direction of the pair of longitudinal extending portions 21, 21.

In the present embodiment, as shown in fig. 3 and 4, the pair of longitudinal extending portions 21, 21 have respective lengths of three vertebrae L3 to L5 from below among five vertebrae L1 to L5 corresponding to the lumbar vertebra L of the lumbar region W when the lumbar protector 1 is attached to the lumbar region W. For example, the pair of longitudinal extensions 21, 21 may be formed to have a length of 70 to 110mm in the vertical direction. The two vertebrae L4, L5 from below of the lumbar vertebra L bear the most load according to the movement of the lumbar region W, but the pair of longitudinal extending portions 21, 21 are formed to have a length including the two vertebrae L4, L5 bearing the most load, whereby the local movement of the lumbar region W bearing the most load can be effectively restricted. However, the length of the longitudinal extension portions 21, 21 is not particularly limited as long as the movement in the front-rear direction of the lumbar region W can be mainly restricted, and may be a length corresponding to at least a part of the lumbar vertebra L, and may be a length corresponding to two or less vertebrae or four or more vertebrae, for example.

In the present embodiment, as shown in fig. 1, each of the pair of longitudinally extending portions 21, 21 is formed in a substantially rectangular sheet shape, and has a shape in which corners of inner sides (sides facing each other) of substantially rectangular upper end sides are cut off. Thus, the frame member 2 is formed such that the interval D becomes larger in a horn shape as it goes toward the upper end sides of the pair of longitudinal extending portions 21, 21. More specifically, the interval D is formed to have substantially the same size from the lower ends of the longitudinally extending portions 21, 21 to the vicinity of the center, and gradually becomes larger from the vicinity of the center of the longitudinally extending portions 21, 21 toward the tip side. The pair of longitudinal extending portions 21, 21 are not subjected to a force at the inner corner portions on the upper end side when the waist portion W is bent backward, and therefore can be suppressed from being deformed as if they are rotated outward in the left-right direction. Therefore, the pair of longitudinal extending portions 21, 21 effectively restrict the backward bending operation of the waist portion W in order to mainly cause the backward bending of the waist portion W. However, the shape of the pair of longitudinal extending portions 21, 21 is not particularly limited as long as they extend substantially parallel to each other with the interval D therebetween along the direction in which the lumbar vertebrae L extend, and may be a shape different from the illustrated shape, such as a substantially rectangular shape without a cutout portion.

The distance D between the pair of longitudinal extending portions 21, 21 is not particularly limited as long as the pair of longitudinal extending portions 21, 21 can be arranged on the left and right of the lumbar vertebra L with the lumbar vertebra L interposed therebetween. For example, the interval D is preferably larger than at least the width of the distal end portion of the ratchet protrusion SP of the lumbar vertebra L in the left-right direction (see fig. 3 and 4). For example, the distance D can be set to 10 to 40 mm. The spine protrusion SP protrudes rearward from the lumbar vertebra L (toward the skin of the waist W), and thereby protrudes rearward from the surface of the skin corresponding to the spine protrusion SP. When the waist protector 1 is attached to the waist W, as shown in fig. 3 and 4, the gap 24 between the pair of longitudinal extensions 21, 21 is positioned at the position of the spinous process SP, thereby substantially preventing the skin corresponding to the spinous process SP from coming into contact with the longitudinal extensions 21, and suppressing unnecessary irritation (pain or the like) from being applied to the skin between the spinous process SP and the longitudinal extensions 21, 21.

As shown in fig. 3 and 4, the laterally extending portion 22 is attached to the waist portion W so that the direction in which the laterally extending portion 22 extends intersects (is substantially orthogonal to in the illustrated example) the direction in which the lumbar vertebrae L extend, and mainly restricts movement of the waist portion W in the left-right direction (for example, twisting of the waist portion W). The laterally extending portion 22 is connected to the pair of longitudinally extending portions 21, 21 in order to connect the pair of longitudinally extending portions 21, 21 to each other as shown in the drawing, whereby the deformation of the laterally extending portion 22 is restricted not only by the elastic restoring force of the laterally extending portion 22 but also by the elastic restoring force of the pair of longitudinally extending portions 21, and therefore, compared with the case where the laterally extending portion 22 is disposed independently, the resistance against the waist portion W can be increased, and the movement of the waist portion W can be restricted more firmly. In the present embodiment, the upper end of the lateral extension portion 22 is connected to the lower ends of the pair of longitudinal extension portions 21, and the lower end sides of the pair of longitudinal extension portions 21, 21 are connected to each other with respect to the lateral extension portion 22. Thereby, the frame member 2 is formed in a substantially U shape as a whole. The lateral extension portion 22 is connected to the lower ends of the pair of longitudinal extension portions 21, 21 disposed along the lumbar vertebra L, and can be disposed near the sacrum S and the ilium I below the lumbar vertebra L to restrict the movement of the sacrum S and the ilium I, and can restrict the movement of the lumbar vertebra L with respect to the sacrum S and the ilium I in cooperation with the pair of longitudinal extension portions 21, 21. However, the laterally extending portion 22 may be any as long as it can connect the pair of longitudinally extending portions 21, 21 to each other, and may be any other position than the lower end side of the longitudinally extending portions 21, 21.

In the present embodiment, as shown in fig. 1 and 2, the lateral extension portion 22 is formed in a substantially rectangular sheet shape. As shown in fig. 3 and 4, the lateral extension 22 is formed to have a dimension between the posterior and superior iliac spines P, P of the left and right ilia I, I of the sacrum S as the bottom plate of the lumbar L when the lumbar protector 1 is attached to the lumbar region W. For example, the lateral extension 22 can be formed to have a length of 100 to 120mm in the left-right direction. The lateral extension part 22 is attached to the vicinity of the sacrum S and the ilium I, and restricts the movement of the sacroiliac joint between the sacrum S and the ilium I, and also restricts the movement of the lumbosacral joint between the lumbar vertebra L and the sacrum S in cooperation with the pair of longitudinal extension parts 21, 21. However, the shape and size of the lateral extending portion 22 are not particularly limited as long as it is configured to extend in a direction intersecting the direction in which the pair of longitudinal extending portions 21, 21 extend and connect the pair of longitudinal extending portions 21, 21 to each other.

As shown in fig. 1, the frame member 2 may further include a downward extending portion 23 extending downward from the lower end of the lateral extending portion 22. The lower extending portion 23 is bonded to the waist portion W together with the lateral extending portion 22, and regulates the movement of the waist portion W in cooperation with the pair of longitudinal extending portions 21, 21 and the lateral extending portion 22. In the present embodiment, the lower extending portion 23 is provided so as to be positioned substantially at the center of the lower end of the lateral extending portion 22 on an extension line extending through the gap 24 between the pair of longitudinal extending portions 21, 21 and to extend substantially parallel to the pair of longitudinal extending portions 21, 21. In the present embodiment, as shown in fig. 1 to 4, the lower extension portion 23 is formed in a substantially rectangular sheet shape and is formed to correspond to a length from the vicinity of the center of the sacrum S to a position closer to the center than the lower end of the sacrum S when the waist protector 1 is attached to the waist W. For example, the lower extension 23 may be formed to have a length of 10 to 30mm in the vertical direction. The lower extension 23 is attached to a position corresponding to the sacrum S, and thereby mainly restricts the movement of the sacrum S and the ilium I in cooperation with the lateral extension 22. For example, the frame member 2 has the lower extension portion 23, and thus the installation area of the position corresponding to the sacrum S is increased, and thus the movement of the lumbar vertebra L with respect to the sacrum S is more firmly restricted by being more firmly fixed to the sacrum S. Further, since the frame member 2 has the lower extending portion 23, for example, as shown in fig. 5, when the waist portion W is bent backward, the frame member 2 is bent backward (a state of a two-dot chain line), but at this time, by applying a stimulus (see an arrow in fig. 5) to the skin of the lower extending portion 23 corresponding to the sacrum S by the elastic restoring force of the frame member 2, the user perceives the waist portion W as being bent backward, and intentionally restricts the further large amount of bending backward of the waist portion W. In this way, the movement of the waist W can be more reliably restricted by the frame member 2 having the downwardly extending portion 23. However, the position, the extending direction, and the size of the lower extending portion 23 are not particularly limited as long as the lower extending portion extends downward from the lower end of the lateral extending portion 22. The lower extending portion 23 may be provided at a position shifted in the lateral direction from substantially the center of the lower end of the lateral extending portion 22, may extend in a direction inclined with respect to the pair of longitudinal extending portions 21, or may be formed to extend to the length of the lower end of the sacrum S, for example.

In the frame member 2 of the present embodiment, as shown in fig. 1 and 2, the pair of longitudinally extending portions 21, the laterally extending portion 22, and the downwardly extending portion 23 are formed integrally in a sheet shape. The waist protector 1 is easy to transport (carry) by forming the skeleton member 2 into a sheet shape, and hardly causes other people to notice even if it is attached to the waist W. The thickness of the skeleton member 2 can be appropriately determined in accordance with the elastic restoring force necessary for restricting the movement of the waist portion W, and is preferably 0.05 to 10.0mm, more preferably 0.1 to 5.0mm, and even more preferably 0.15 to 1.5mm, from the viewpoint of the portability and the wearability described above, for example. However, the frame member 2 is not limited to the present embodiment as long as it has an elastic restoring force to regulate the movement of the waist portion W. The pair of vertical extending portions 21, horizontal extending portion 22, and lower extending portion 23 may be formed in other shapes such as a rod shape, or may be formed separately and then connected to each other to form the frame member 2.

The material of the frame member 2 is not particularly limited as long as it has an elastic restoring force necessary for restricting the movement of the waist portion W. As the material having an elastic restoring force, for example, a hard resin material such as polyethylene terephthalate (PET), polypropylene (PP), or Polyethylene (PE) can be used as the skeleton member 2. Since the waist protector 1 can be made lightweight by using a hard resin material as a material of the skeleton member 2, it is easy to transport (carry), and to attach the waist protector to the waist W, and even if the waist protector is attached to the waist W, the burden on the waist W due to the weight of the waist protector 1 can be reduced.

The attachment member 3 is a member that attaches the frame member 2 to the waist portion W and holds the frame member 2 with respect to the waist portion W. In the present embodiment, as shown in fig. 1 to 5, the attachment member 3 is formed in a sheet shape, the skeleton member 2 is attached to the rear surface (the surface on the opposite side to the skin of the waist W) of the attachment member 3, and the front surface (the surface on the skin side of the waist W) of the attachment member 3 is attached to the waist W, whereby the skeleton member 2 is attached to the waist W. Therefore, the attachment member 3 is positioned between the skeleton member 2 and the skin of the waist W and functions as a cushion therebetween, thereby reducing unnecessary irritation (pain or the like) to the skin of the waist W due to direct contact between the skeleton member 2 and the skin of the waist W and improving the wearing feeling of the waist protector 1 to the waist W. However, the attachment member 3 is not limited to the present embodiment as long as it attaches the frame member 2 to the waist portion W and holds the frame member 2 with respect to the waist portion W, and may cover the frame member 2 from the rear surface side of the frame member 2, or may be configured to attach the frame member 2 to the waist portion W so as to be in direct contact with the waist portion W.

In the present embodiment, as shown in fig. 1, the attachment member 3 has a larger attachment area than the frame member 2, and is formed in a size such that the entire frame member 2 can be arranged in the attachment surface. The adhesive member 3 has a larger adhesive area than the frame member 2, so that the frame member 2 can be more reliably adhered to the waist W, and the elastic restoring force of the frame member 2 can be influenced to a wider range than the frame member 2 by the adhesive member 3. The attachment member 3 is formed in a size corresponding to the waist W, and is not attached to at least the abdomen and does not press the abdomen. For example, the attachment member 3 may be formed to have a dimension of 160 to 180mm in the vertical direction and 160 to 180mm in the horizontal direction. However, the size of the attachment member 3 is not particularly limited as long as the frame member 2 is attached to the waist W without pressing the abdomen.

In the present embodiment, as shown in fig. 2, the joining member 3 includes a nonwoven fabric layer 31 to which the skeleton member 2 is joined, and an adhesive layer 32 to join the nonwoven fabric layer 31 to the waist portion W. The joining member 3 is formed by laminating a nonwoven fabric layer 31 and an adhesive layer 32. The nonwoven fabric layer 31 is made of a stretchable nonwoven fabric and is configured to be stretchable so as to at least partially correspond to the stretching of the skin of the waist W when the waist protector 1 is attached to the waist W. The skeleton member 2 is attached to the surface of the nonwoven fabric layer 31 by an adhesive member a such as a known double-sided tape, and is attached to the waist portion W via the nonwoven fabric layer 31 and the adhesive layer 32. In this way, the skeleton member 2 is bonded to the waist portion W via the nonwoven fabric layer 31, and thus the stretchability of the nonwoven fabric layer 31 enables the waist protector 1 to have a capability of following the skin expansion and contraction, and thus the skin load such as skin tension can be reduced when the waist protector 1 is used.

The nonwoven fabric layer 31 is not particularly limited as long as it can be stretched so as to at least partially correspond to the stretching of the skin and has a strength against the elastic restoring force of the chassis member 2, and may be formed of a known nonwoven fabric. For example, the nonwoven fabric constituting the nonwoven fabric layer 31 is preferably a nonwoven fabric requiring a force of 8 to 19N for achieving an elongation of 20% from the viewpoint of required stretchability and strength, and for example, a nonwoven fabric made of polyester fibers can be suitably used.

The adhesive layer 32 is not particularly limited as long as it can adhere the nonwoven fabric layer 31 to the skin of the waist W, hold the nonwoven fabric layer 31 and the skeleton member 2 with respect to the waist W, and be peeled off from the waist W by the hand of the user. The adhesive layer 32 is preferably made of an adhesive having an adhesive strength of 3 to 11N measured in a width of 25mm using an SUS304 plate based on JIS Z0237, and may be made of a known acrylic adhesive or the like, for example.

The adhesive member 3 may contain, for example, a cold-feeling component such as menthol or salicylic acid which can alleviate pain and swelling while feeling cold, a hot-feeling component such as a capsicum extract or capsaicin which can improve the blood flow of the skin and can feel hot, or a medicinal component such as a non-steroidal anti-inflammatory analgesic such as indomethacin, diclofenac, felbinac, loxoprofen, or ketoprofen. The waist protector 1 can restrain the movement of the waist W and provide an analgesic effect to the waist W by including the cooling component, the heating component, or the medicinal component in the adhesive member 3, thereby more rapidly relieving the lumbago. In the case where the joining member 3 includes the nonwoven fabric layer 31 and the adhesive layer 32, the adhesive layer 32 can contain a cool component, a heat component, or a medicinal component.

As shown in fig. 1, the attachment member 3 may have a high-elongation portion 33 that elongates to a greater extent than other portions of the attachment member 3 in accordance with the elongation of the skin of the waist W when the waist protector 1 is attached to the waist W. Since the adhesive member 3 has the high extension portion 33, when the skin is extended in accordance with the movement of the waist W, even if the other portion of the adhesive member 3 is not sufficiently extended, the high extension portion 33 is extended to a greater extent, and therefore the adhesive member 3 deforms in accordance with the extension of the skin, and the skin load such as skin tension is reduced by the adhesive member 3. In the present embodiment, the high-elongation portion 33 is formed in a broken line shape intermittently having a cut so as to extend substantially parallel to the direction in which the pair of longitudinal extending portions 21, 21 extend, at a position corresponding to each of the pair of longitudinal extending portions 21, 21. Since the high-elongation portion 33 is disposed so as to extend in the vertical direction, when the skin of the waist W is elongated in the lateral direction, the high-elongation portion 33 is elongated in the lateral direction, thereby reducing the load on the skin in the lateral direction. In particular, in the present embodiment, as shown in fig. 1, the high-elongation portion 33 is provided also in the region where the skeleton member 2 is not provided, and the high-elongation portion 33 in this region can be elongated without being restricted by the skeleton member 2, and therefore can be deformed more easily following the elongation of the skin. However, the position of the high-extension portion 33 is not particularly limited as long as the load on the skin of the waist W can be reduced, and the high-extension portion may be provided so as to extend in a direction substantially perpendicular to the direction in which the pair of longitudinal extension portions 21, 21 extend, for example. Further, the high extension portion 33 is provided in the form of a broken line in the present embodiment, but may be formed of another form such as a member having a higher elongation than other portions of the adhesive member 3 as long as it can be extended more largely than other portions in accordance with the extension of the skin of the waist W.

As shown in fig. 1, the attachment member 3 may have an alignment portion 34 for aligning the waist protector 1 along the lumbar vertebra L when attaching the waist protector 1 to the waist W. In the present embodiment, the positioning portion 34 is configured to be able to be perceived by the touch of the user's fingertip. More specifically, the positioning portion 34 is disposed substantially at the center of the upper end of the attachment member 3 on an extension line extending through the gap 24 between the pair of longitudinal extending portions 21, and is formed as a recess recessed from the upper end. As shown in fig. 3 and 4, when the positioning portion 34 is to attach the waist protector 1 to the waist W, the positioning portion 34 is positioned on a line on which the plurality of ratchet protrusions SP of the lumbar vertebra L are arranged, whereby the waist protector 1 can be positioned along the lumbar vertebra L. For example, the kinesiology tape of patent document 2 does not have a portion that serves as a mark for a specific position on the waist, and thus it is difficult for the kinesiology tape to be attached to an appropriate position on the waist by one person. However, in the present embodiment, the attachment member 3 has the positioning portion 34, and thus the user can attach the waist protector 1 to an appropriate position of the waist W even by one person. The positioning portion 34 is not limited to the illustrated example as long as it is a mark for positioning the waist protector 1 along the lumbar vertebra L, and may be formed as a protrusion protruding from the upper end, for example.

As described above, the waist protector 1 may have the release paper 4. The waist protector 1 has the release paper 4, and therefore, it is possible to suppress the sticking of the sticking members 3 to the storage place or the sticking of the sticking members 3 to each other due to the bending of the sticking members 3 during the storage and transportation of the waist protector 1, and therefore, the storage and transportation are easy. In the present embodiment, as shown in fig. 1 and 2, the release paper 4 has a non-attached portion 41 that protrudes downward from the lower end of the attached member 3 and is not attached to the attached member 3. Since the release paper 4 has the non-attachment portion 41 below the attachment member 3, when the user attaches the waist protector 1 to the waist W by himself, the user can easily pull the release paper 4 off from the attachment member 3 by extending his or her hand to the non-attachment portion 41 as compared with the case where the non-attachment portion 41 is provided above the attachment member 3, and the waist protector 1 can be attached to the waist W more easily. The release paper 4 has a cut line so as to be separable into a plurality of pieces and peeled off from the sticking member 3 (in the present embodiment, at the same position as the high extension portion 33 of the sticking member 3). Therefore, the user can peel off the release paper 4 from the attachment member 3 in stages, so that the attachment member 3 can be attached to the waist portion W in stages, and the attachment members 3 can be prevented from being attached to each other, and the attachment member 3 can be attached to the waist portion W more accurately.

Next, a method of using the waist protector 1 of the present embodiment, and an operation and an effect thereof will be described with reference to the drawings. However, the following description is only an example, and does not limit the configuration and the use method of the waist protector of the present invention.

The user of the waist protector 1 first positions the waist protector 1 at the waist W with the release paper 4. At this time, as shown in fig. 3 and 4, the positioning portion 34 of the attachment member 3 is positioned on the line on which the plurality of ratchet projections SP of the lumbar vertebra L are arranged, the lower end of the gap 24 between the pair of longitudinal extending portions 21, 21 is positioned below the lowest ratchet projection SP of the lumbar vertebra L, and the lateral extending portion 22 is positioned so as to be laterally bridged between the iliac posterior superior spines P, P of the right and left iliac I, I. The user can position the waist protector 1 at an appropriate position on the waist W by one person by providing the aligning portion 34 to the attachment member 3.

Next, the user peels the release paper 4 from the adhesive member 3 with the waist protector 1 positioned on the waist W, and attaches the adhesive member 3 to the skin of the waist W. As shown in fig. 1, the release paper 4 has a non-attached portion 41 extending downward from the lower end of the attachment member 3, and the user peels the release paper 4 from the attachment member 3 with the non-attached portion 41 as a starting point, thereby attaching the attachment member 3 to the skin of the waist W. Since the non-bonded portion 41 is provided at the lower end of the bonded member 3, the user can easily reach the non-bonded portion 41 with his or her hand and easily peel the release paper 4. Further, since the release paper 4 can be separated into three pieces, the user can sequentially and stepwise adhere the part of the adhesive member 3 from which the release paper 4 is peeled off to the skin of the waist W while separating the release paper 4 piece by piece along the cutting lines (at the same positions as the high-elongation portions 33), and thus the adhesion of the adhesive members 3 to each other can be suppressed, and the adhesive member 3 can be more accurately adhered to the waist W.

As described above, as shown in fig. 3 and 4, the frame member 2 is disposed such that the pair of longitudinal extensions 21, 21 are positioned on the left and right sides of the lumbar vertebra L along the direction in which the lumbar vertebra L extends, the lateral extension 22 is positioned so as to straddle between the posterior superior iliac spines P, P of the ilium I, I on both sides of the sacrum S, and the inferior extension 23 is positioned in the sacrum S. Thus, the movement of the lumbar vertebra L is mainly restricted by the pair of longitudinal extension portions 21, the movement of the sacrum S and the ilium I is mainly restricted by the lateral extension portion 22, and the movement of the waist W is restricted by the pair of longitudinal extension portions 21, 21 and the lateral extension portion 22 in cooperation. Further, by disposing the lower extension portion 23 in the sacrum S, the fixation of the frame member 2 to the sacrum S becomes stronger, and the movement of the lumbar vertebra L with respect to the sacrum S is more restricted. As shown in fig. 5, when the waist portion W is bent backward, the frame member 2 is bent backward, and the skin corresponding to the sacrum S is stimulated by the lower extending portion 23, so that the user who senses the bending backward of the waist portion W is stimulated to restrict the larger backward bending of the waist portion W. In this way, by attaching the skeleton member 2 having the elastic restoring force to the waist portion W via the attachment member 3, the movement of the waist portion W can be regulated without pressing the abdomen.

When the frame member 2 is aligned with the lumbar region W as described above, the gap 24 between the pair of longitudinal extending portions 21, 21 is aligned with the spinous process SP of the lumbar vertebra L. Thus, the skin corresponding to the spinous process SP is prevented from substantially abutting against the pair of longitudinal extensions 21, and is prevented from being unnecessarily irritated via the spinous process SP and the pair of longitudinal extensions 21, 21.

Further, since the adhesive member 3 has the nonwoven fabric layer 31 having stretchability, even if the skin stretches and contracts by the action of the waist portion W, the nonwoven fabric layer 31 stretches and contracts at least partially in accordance with the stretching and contraction of the skin, and therefore the waist protector 1 suppresses the skin from being pulled and improves the wearing feeling of the waist protector 1 on the waist portion W. In particular, since the adhesive member 3 has the high extension portion 33, even if the skin is extended, the high extension portion 33 is extended to a greater extent, and the adhesive member 3 deforms to follow the extension of the skin, thereby further reducing the skin load such as skin tension.

In addition, the waist protector 1 can restrain the movement of the waist W and provide an analgesic effect to the waist W by including the cooling component, the heating component, or the medicinal component in the adhesive member 3, thereby more rapidly relieving the lumbago.
