[First Embodiment]
FIG. 1 is a three-side view (a front view, a side view, and a bottom view) illustrating the configuration of the supporter 1 according to the first embodiment of the present invention, and FIG. 2 is a rear view of the supporter 1. The supporter 1 of 1st Embodiment is an auxiliary tool which supports a user's knee part (exemplification of a movable part), and comprises the mounting part 10 with which a knee part can be mounted | worn.

  The mounting portion 10 is a flat member obtained by cutting a flexible cloth material, and is formed of various materials such as nylon or polypropylene. The mounting portion 10 of the first embodiment has a first surface F1 and a second surface F2. The first surface F1 illustrated in FIG. 1 is a surface located on the side opposite to the body (ie, outside) in a state where the supporter 1 is mounted on the user's body (hereinafter referred to as “mounted state”). The second surface F2 shown in FIG. 2 is a surface opposite to the first surface F1, and is located on the body side (that is, inside) in the wearing state. In the following description, an X direction and a Y direction that are orthogonal to each other are assumed. The XY plane is a plane parallel to the mounting portion 10. The X direction is, for example, the horizontal direction of the supporter 1, and the Y direction is, for example, the vertical direction of the supporter 1.

  The mounting portion 10 of the first embodiment has a planar shape that is line-symmetric with respect to a center line extending in each of the X direction and the Y direction. Specifically, the mounting portion 10 is formed in a planar shape in which the base portion 11 and the plurality of attachment portions 12 (12a1, 12a2, 12b1, 12b2) are integrated. The base portion 11 is a strip-like portion that is long in the X direction. Each of the plurality of attachment portions 12 (12a1, 12a2, 12b1, 12b2) is a portion protruding from the base portion 11 in the X direction. Specifically, as illustrated in FIGS. 1 and 2, the attachment portion 12 a 1 and the attachment portion 12 a 2 are continuous on the negative side in the X direction of the base portion 11, and the attachment portion 12 b 1 and the attachment portion 12 b 2 are the base portion 11. It continues on the positive side in the X direction. The mounting portion 12a1 and the mounting portion 12a2 are spaced apart from each other in the Y direction, and the mounting portion 12b1 and the mounting portion 12b2 are spaced from each other in the Y direction. The tip of each mounting portion 12 (that is, the peripheral edge opposite to the base portion 11) has an arc shape. The peripheral portion (hereinafter referred to as “peripheral portion”) 13 of the mounting portion 10 is subjected to peripheral sewing over the entire periphery. For example, a tape having a predetermined width that borders the periphery of the mounting portion 10 is stitched to the mounting portion 10.

  As illustrated in FIGS. 1 and 2, the attaching / detaching portion 20a is installed on the second surface F2 of the attaching portion 12a1, and the attaching / detaching portion 20b is installed on the second surface F2 of the attaching portion 12a2. The detachable part 20a and the detachable part 20b function as planar fasteners. That is, each of the detachable portion 20a and the detachable portion 20b is detachable from the first surface F1 of the mounting portion 10. As illustrated in FIGS. 1 and 2, the detachable portion 20a is installed so as to partially protrude from the tip of the mounting portion 12a1. Similarly, the detachable portion 20b is installed so as to partially extend from the tip of the mounting portion 12a2. Therefore, there is an advantage that the detachable portion 20a and the detachable portion 20b can be easily detached.

  FIG. 3 is an explanatory diagram of the supporter 1 in the mounted state. As illustrated in FIG. 3, when the supporter 1 is mounted on the user's knee P, the mounting portion 10 is wound around the knee P with the second surface F2 facing the user's knee P. The attaching / detaching part 20a of the attaching part 12a1 is coupled to the first surface F1 of the attaching part 12b1, and the attaching / detaching part 20b of the attaching part 12a2 is joined to the first surface F1 of the attaching part 12b2. For example, when the user steps on the leg portion by pulling the mounting portion 10 while pulling the mounting portion 10 from the inner side (median plane side) to the outer side of the knee portion P (for example, at the time of turning or jumping) It is possible to reduce the burden on the inside of the knee P.

  In the mounting state exemplified above, the band-shaped portion connecting the mounting portion 12a1 and the mounting portion 12b1 and the band-shaped portion connecting the mounting portion 12a2 and the mounting portion 12b2 are the kneecap Pa (so-called knee kid) of the knee portion P. ) In the Y direction. On the other hand, the base body 11 covers the knee back portion Pb (that is, the popliteal surface) and both side surfaces (inner surface and outer surface) of the knee portion P in the mounted state. In FIG. 3, the mounting portion 10 is mounted on the knee P with the mounting portion 12a1 and the mounting portion 12b1 positioned upward. However, the mounting portion 10 is turned upside down so that the mounting portion 12a2 and the mounting portion 12b2 are positioned upward. It is also possible to attach the mounting part 10 to the knee part P in a state of being positioned in the position.

  As illustrated in FIG. 1, a mark 14 is formed on the first surface F1 of the attachment portion 12a1. The mark 14 is a sign (typically a trademark) such as a figure or a symbol for visually identifying the product name of the supporter 1 or the seller, and is formed by printing or embroidery, for example. The mark 14 of the first embodiment has a shape in which the top and bottom are conceived. In FIG. 1, the letter “K” is illustrated as the mark 14. As illustrated in FIG. 1, the mark 14 is formed in the direction in which the X direction is the up-down direction (specifically, the direction in which the distal end side of the mounting portion 12 a 1 is upward).

  In the configuration in which the mark 14 is formed with the Y direction as the vertical direction, the mounting state in which the mounting portion 12a1 and the mounting portion 12b1 are positioned upward, and the mounting state in which the mounting portion 12a2 and the mounting portion 12b2 are positioned upward. The top and bottom of the mark 14 are reversed. And there exists a problem that it looks bad if the mark 14 is reverse in a mounting state. In the first embodiment, since the mark 14 is formed with the X direction as the vertical direction, regardless of the direction in which the supporter 1 is mounted on the knee P, the mark 14 is in the horizontal direction and is not reversed. Therefore, there is an advantage that the appearance when the supporter 1 is mounted is not deteriorated. However, it is also possible to form the mark 14 with the Y direction as the vertical direction.

  As illustrated in FIG. 1, an opening 15 is formed in the mounting portion 10 of the first embodiment. As understood from FIG. 3, the opening 15 is an opening formed in a region corresponding to the knee back portion Pb of the knee portion P in the mounting portion 10. Specifically, the opening 15 is located in the center of each of the X direction and the Y direction in the mounting part 10. The planar shape of the opening 15 in the first embodiment is a shape surrounded by the inner periphery A1, the inner periphery A2, the inner periphery A3, and the inner periphery A4. The inner peripheral edge A1 and the inner peripheral edge A2 are linear parallel to the Y direction. On the other hand, the inner peripheral edge A3 and the inner peripheral edge A4 have a curved shape (for example, an arc shape) that connects the ends of the inner peripheral edge A1 and the inner peripheral edge A2 to each other.

  As illustrated in FIGS. 1 and 2, a covering portion 30 is joined to the mounting portion 10. In the first embodiment, the covering portion 30 is joined to the second surface F2 of the mounting portion 10. That is, the covering portion 30 is located on the knee portion P side when viewed from the mounting portion 10. The covering portion 30 is formed of a breathable cloth fabric. Specifically, a mesh-like cloth fabric (mesh) formed of various materials such as nylon or polypropylene is preferably used as the covering portion 30. The mounting portion 10 and the covering portion 30 are different in stretchability. Specifically, the extension amount when the extension portion 10 is extended with a predetermined tensile force is different between the mounting portion 10 and the covering portion 30. In 1st Embodiment, the case where the coating | covering part 30 has a stretching property higher than the mounting part 10 (namely, it is easy to extend) is assumed. In addition, although the covering part 30 can also be comprised with one cloth cloth, in order to ensure the intensity | strength of the covering part 30, it is also possible to comprise the covering part 30 by overlapping a plurality of cloth cloths. is there.

  As illustrated in FIGS. 1 and 2, the covering portion 30 of the first embodiment is joined to the second surface F <b> 2 of the mounting portion 10 so as to overlap the opening 15. That is, the opening 15 is closed by the covering portion 30. As described above, according to the configuration in which the opening portion 15 of the mounting portion 10 is covered with the breathable covering portion 30, the knee back portion Pb and the supporter 1 are compared with the configuration in which the opening portion 15 is not formed in the mounting portion 10. It is possible to reduce the stuffiness in the space between. In addition, although the structure which does not install the coating | coated part 30 can only be assumed if air permeability is ensured, the intensity | strength of the supporter 1 may be insufficient. In 1st Embodiment, there exists an advantage that dripping can be reduced by ensuring the intensity | strength of the supporter 1 by installing the coating | coated part 30 which overlaps with the opening part 15. As shown in FIG.

  As illustrated in FIGS. 1 and 2, the planar shape of the covering portion 30 in the first embodiment is a shape surrounded by the peripheral edge B1, the peripheral edge B2, the peripheral edge B3, and the peripheral edge B4. The peripheral edge B1 and the peripheral edge B2 are linear shapes parallel to the X direction, and extend in the X direction along the peripheral edge of the mounting portion 10. The peripheral edge B3 and the peripheral edge B4 have a curved shape (for example, an arc shape) that connects the ends of the peripheral edge B1 and the peripheral edge B2 to each other.

  The covering portion 30 having the shape exemplified above is stitched to the center of the mounting portion 10 in the X direction. Specifically, the covering portion 30 is stitched to the mounting portion 10 by a curved suture line L3 along the peripheral edge B3 and a curved suture line L4 along the peripheral edge B4. Further, as illustrated in FIG. 2, a portion (hereinafter referred to as “joining portion”) 31 in the vicinity of each of the peripheral edge B 1 and the peripheral edge B 2 in the covering portion 30 is sewn to the peripheral portion 13 of the mounting portion 10 by peripheral sewing. To be sutured. Further, the covering portion 30 of the first embodiment is mounted by a suture line L1 along the Y direction in the vicinity of the inner peripheral edge A1 of the opening 15 and a suture line L2 along the Y direction in the vicinity of the inner peripheral edge A2 of the opening 15. Sutured to part 10. The suture lines (L1 to L4) are stitches made of, for example, a thread.

  As described above, the joint portion 31 located in the vicinity of the peripheral edge B 1 and the peripheral edge B 2 in the covering portion 30 is stitched to the mounting portion 10. As illustrated in FIG. 2, the joint portion 31 is close to the peripheral edge portion 13 of the mounting portion 10 and is separated from the opening portion 15. That is, the mounting portion 10 and the covering portion 30 are not stitched in the vicinity of the inner peripheral edge A3 and the inner peripheral edge A4 of the opening 15. Accordingly, the inner peripheral edge A 3 or the inner peripheral edge A 4 of the opening 15 can be separated from the covering portion 30.

  By the way, in the configuration in which the inner peripheral edge A3 and the inner peripheral edge A4 of the opening 15 are stitched to the covering portion 30 (hereinafter referred to as “Comparison 1”), the mounting portion 10 and the covering portion 30 that have lower stretchability (first) In the embodiment, the other expansion and contraction is restricted by the mounting portion 10). In contrast to the above comparative 1, in the first embodiment, the joint portion 31 between the covering portion 30 and the mounting portion 10 is separated from the opening 15. It is alleviated that the other expansion and contraction is restricted by the lower property. Therefore, there is an advantage that it is possible to provide the supporter 1 rich in elasticity as compared with the comparative 1. However, the inner peripheral edge A 3 and the inner peripheral edge A 4 of the opening 15 can be sewn to the covering portion 30.

  As understood from FIGS. 1 and 2, a substantially arcuate space R1 sandwiched between the attachment portion 10 and the covering portion 30 is formed between the suture line L1 and the suture line L3. Similarly, a substantially arcuate space R2 sandwiched between the attachment portion 10 and the covering portion 30 is formed between the suture line L2 and the suture line L4. An elastic body 40a is accommodated in the space R1, and an elastic body 40b is accommodated in the space R2. That is, a pair of elastic bodies (elastic body 40a and elastic body 40b) are installed in the mounting portion 10 of the first embodiment.

  As illustrated in FIG. 3, one of the elastic body 40 a and the elastic body 40 b overlaps the inner side surface (that is, the side surface on the median surface side) of the knee portion P, and the other of the elastic body 40 a and the elastic body 40 b is outside the knee portion P. It overlaps the side surface (ie, the side surface opposite to the median surface). That is, the elastic body 40a and the elastic body 40b are installed so as to sandwich the knee portion P from the left and right. The elastic body 40a and the elastic body 40b have the same structure and characteristics. Therefore, in the following description, when it is not necessary to distinguish the elastic body 40a and the elastic body 40b from each other, they are comprehensively described as “elastic body 40” and the individual descriptions thereof are omitted.

  The elastic body 40 is a member that can be elastically deformed. The elastic body 40 of 1st Embodiment supports the said knee part P by elastically pressing the side surface of the knee part P in a mounting state. Therefore, the elastic body 40 can also be referred to as a support member (pad) that supports the knee P. Further, the knee P is elastically deformed by the bending of the knee P, and is elastically restored when the knee P is extended, thereby assisting the extension of the knee P. That is, the load of the operation of the user bending and stretching the knee P is reduced. The elastic body 40 also realizes a function of protecting the knee portion P by absorbing an external impact by elastic deformation.

  As illustrated in FIG. 1, a plurality of through holes 16 are formed in a portion of the mounting portion 10 that overlaps each of the elastic body 40 a and the elastic body 40 b. Each through-hole 16 of the first embodiment is a planar opening that is long in a direction inclined with respect to the X direction and the Y direction. Specifically, six through holes 16 arranged in the Y direction with a space between each other are formed in a region overlapping the elastic body 40a. Similarly, six through-holes 16 are formed in a region overlapping the elastic body 40b so as to be spaced apart from each other. Each through-hole 16 overlapping the elastic body 40a communicates the inside and outside of the space R1, and each through-hole 16 overlapping the elastic body 40b communicates the inside and outside of the space R2. As described above, in the first embodiment, since the through hole 16 is formed in the mounting portion 10, the mounting portion 10 is easily deformed so as to follow the flexion (bending or extension) of the knee P. Therefore, for example, when the knee portion P is bent and stretched in the mounted state, it is possible to suppress distortion such as wrinkling or twisting of the mounting portion 10. Further, the user can visually confirm that the elastic body 40 is installed through the through hole 16. The planar shape of the through hole 16 is arbitrary.

  4 is a cross-sectional view taken along line IV-IV in FIG. As illustrated in FIG. 4, in each of the space R <b> 1 and the space R <b> 2, an insertion part 35 positioned between the mounting part 10 and the elastic body 40 is installed. The insertion part 35 is a mesh-like cloth cloth (mesh). The mesh of the insertion part 35 is rougher than that of the covering part 30. The insertion part 35 is exposed through each through hole 16 formed in the mounting part 10. The user can visually recognize the elastic body 40 through each through hole 16 and the mesh of the insertion portion 35. Note that the insertion portion 35 may be omitted.

  FIG. 5 is a plan view and a side view of the elastic body 40. As illustrated in FIGS. 4 and 5, the elastic body 40 of the first embodiment includes a first member 41 and a second member 42 that are configured separately from each other. Each of the first member 41 and the second member 42 is a plate-like member formed in the same shape as each other. For example, in a state where the first member 41 and the second member 42 are not attached to the user's body (a state in which no external force acts), Keep the shape of. The first member 41 and the second member 42 are installed in the mounting portion 10 with the surfaces facing each other in close contact. The first member 41 and the second member 42 of the first embodiment are bonded to each other with, for example, an adhesive.

  As illustrated in FIG. 4, the elastic body 40 is mounted on the mounting portion 10 so that the first member 41 is positioned on the mounting portion 10 side (the insertion portion 35 side) and the second member 42 is positioned on the covering portion 30 side. Installed. Therefore, in the mounted state, the second member 42 is located on the knee portion P side when viewed from the first member 41. That is, the second member 42 is located between the first member 41 and the knee portion P.

  The first member 41 and the second member 42 are formed of different materials. Specifically, the first member 41 is a foam formed of a resin material such as EVA (Ethylence Vinyl Acetate). On the other hand, the second member 42 is a low-resilience foam formed of a resin material such as a styrene elastomer. As described above, the elastic body 40 of the first embodiment is formed of a resin material. Therefore, for example, when compared to a supporter that supports the body by a metal member such as a coil stay of Patent Document 1, the supporter 1 of the first embodiment is a sporting scene in which the body can frequently come into contact with each other. Particularly preferred. However, the supporter 1 can be used for medical use or rehabilitation, for example. The first member 41 mainly contributes to the function of supporting the knee portion P, and the second member 42 mainly contributes to the function of absorbing an impact from the outside by elastic deformation.

  Specifically, the second member 42 is formed of a low-rebound foam having a rebound resilience (JIS: Japanese Industrial Standards (JIS) K6301) of 20% or more and 60% or less. In a more preferred aspect, the second member 42 is formed of a low-rebound foam having a rebound resilience (JIS K6301) of 30% or more and 50% or less. Here, in a general low-resilience foam having a rebound resilience of less than 20%, when the pressure is continuously applied over a long period of time, the rebound force is denatured (so-called sag state). obtain. On the other hand, impact absorbency is reduced in a high resilience (high elasticity) foam. The inventor of the present application preferably uses, as a material for the second member 42, a low-rebound foam having a rebound resilience within the above-described range from the viewpoint of achieving both a reduction in rebound force (sagging) and maintenance of shock absorption. I found out. That is, according to the configuration in which the second member 42 is formed of a foam having a rebound resilience of 20% or more and 60% or less (more preferably 30% or more and 50% or more), the rebound force is suppressed from being reduced and the impact is absorbed. There is an advantage that the maintenance of sex can be achieved at a high level. Note that the first member 41 can also be referred to as a member having a larger rebound resilience than the second member 42 (a member having higher repulsion). In addition, the second member 42 is a foam that has excellent impact absorbability, a repulsive force that is unlikely to decrease, and a property that does not easily harden at low temperatures.

  In addition, the 1st member 41 and the 2nd member 42 are formed with the foam of the closed cell structure in which the internal bubble was mutually independent (thus it is hard to let a liquid and gas pass). Specifically, a foam having a closed cell structure in which the ratio of the volume of bubbles to the entire volume is 25% or more is suitable as a material for the first member 41 or the second member 42. According to the above configuration, since it is difficult to be deformed when an external force is applied compared to a foam (for example, a sponge) having an open cell structure in which the internal bubbles communicate with each other, the shock absorbing property is reduced. There is an advantage that it is easy to ensure.

  By the way, in order to firmly support the user's body, it is desirable that the elastic body is hard. However, the harder the elastic body, the more difficult it is to follow the deformation of the knee P. In a state where the elastic body does not follow the deformation of the knee portion P, only a part of the elastic body presses the user's body locally, and thus the user feels uncomfortable (for example, pain or discomfort). There's a problem. Considering the above circumstances, in the first embodiment, the first member 41 and the second member 42 are different in hardness. Specifically, the second member 42 is softer than the first member 41. Accordingly, the first member 41 firmly supports the user's knee P, while the second member 42 deforms so as to follow the deformation (for example, bending and stretching) of the knee P. As understood from the above description, in the first embodiment, the knee portion P of the user is firmly supported as compared with the case where the elastic body 40 is configured by only the second member 42. In addition, it is possible to improve the wearing feeling (feeling of fitting) compared to the case where the elastic body 40 is configured by only the first member 41. That is, according to the first embodiment, it is possible to improve the wearing feeling while maintaining the performance of the supporter 1 supporting the knee P.

The hardness of the first member 41 and the second member 42 will be described in detail. In the following description, 25% compression hardness H specified in JIS K6767 is used as an index of hardness. The 25% compression hardness H is defined by the following mathematical formula (a).
H = Q / WL ... (a)
The symbol Q in the formula (a) is a weight of the sample after compression. Specifically, the sample placed between the flat plates is stopped by compressing at a speed of 10 mm / min by 25% of the thickness when no load is applied, and the weight after 20 seconds from the stop of the compression is expressed by the formula (a). Is used as a weighting factor Q. Further, the symbol W in the formula (a) is the width (mm) of the sample, and the symbol L in the formula (a) is the length (mm) of the sample.

  In the first embodiment, the 25% compression hardness H1 of the first member 41 is greater than the 25% compression hardness H2 of the second member 42 (H1> H2). For example, the 25% compression hardness H1 of the first member 41 is 20 N / cm 2 or more, and the 25% compression hardness H2 of the second member 42 is 15 N / cm 2 or less. According to the above configuration, it is possible to effectively achieve both the maintenance of the support function by the first member 41 and the improvement of the wearing feeling by the second member 42. More specifically, the 25% compression hardness H1 of the first member 41 is 20 N / cm 2 or more and 40 N / cm 2 or less, and the 25% compression hardness H2 of the second member 42 is 10 N / cm 2 or less. . In a more preferred aspect, the 25% compression hardness H1 of the first member 41 is 27 N / cm 2 or more and 30 N / cm 2 or less, and the 25% compression hardness H2 of the second member 42 is 2 N / cm 2 or more and 6 N. / cm2 or less.

  As illustrated in FIGS. 4 and 5, the first member 41 and the second member 42 have different thicknesses. Specifically, the thickness T1 of the first member 41 is larger than the thickness T2 of the second member 42 (T1> T2). For example, the thickness T1 of the first member 41 is 4 mm or more and 5 mm or less, and the thickness T2 of the second member 42 is about 3 mm. However, the relationship between the thickness T1 of the first member 41 and the thickness T2 of the second member 42 is not limited to the above example. In other words, depending on the material of the first member 41 or the second member 42, the configuration in which the first member 41 and the second member 42 have the same thickness (T1 = T2), or the thickness T2 of the second member 42 is A configuration (T2> T1) larger than the thickness T1 of the first member 41 may also be employed.

  If the elastic body 40 is too thick, when the supporter 1 is worn on both knees of the user, the parts corresponding to the elastic body 40 contact each other between the left knee and the right knee, and the user feels uncomfortable. Or may impede user movement. Considering the above circumstances, the total thickness (T1 + T2) of the first member 41 and the second member 42 is desirably, for example, 10 mm or less, and more preferably 8 mm or less.

  Further, the first member 41 and the second member 42 have different colors. For example, the first member 41 located on the mounting portion 10 side is colored in a high chroma color such as red, and the second member 42 is colored in a low chroma color such as gray. The color of the first member 41 of the elastic body 40 is also different from the color (for example, black) of the mounting portion 10 and the insertion portion 35. Therefore, the user can clearly see the elastic body 40 through each through hole 16 of the mounting portion 10 and the mesh of the insertion portion 35. There is also an advantage that it is excellent in design aesthetics (design) compared to a configuration in which the through-hole 16 is not formed (that is, a configuration in which the elastic body 40 cannot be visually recognized from the outside).

  In FIG. 5, the front side and the rear side of the knee portion P in the mounted state are illustrated by arrows. As illustrated in FIG. 5, a plurality of (two in the illustration of FIG. 5) cutout portions 46 are formed on the peripheral edge (hereinafter referred to as “rear edge portion”) 45 of the elastic body 40 on the rear side of the knee portion P. Formed at intervals. Each of the plurality of notches 46 is a recess that is locally recessed with respect to the rear edge 45. When the user bends the knee P, the elastic body 40 is elastically deformed so that the width of each notch 46 is narrowed. That is, the elastic body 40 is easily deformed so as to follow the bending and stretching of the knee portion P as compared with the configuration in which the cutout portion 46 is not formed in the elastic body 40. Therefore, the possibility that distortion such as wrinkles and twisting occurs in the elastic body 40 when the knee P is bent and stretched is reduced.

  As illustrated in FIG. 5, the peripheral edge (hereinafter referred to as “front edge”) 47 of the elastic body 40 on the front side of the knee portion P has a convex shape. Specifically, the convex shape is a plane in which a point on the line segment S is located on the elastic body 40 when assuming a line segment S connecting two arbitrary points on the front edge portion 47 in plan view. Shape. The front edge portion 47 illustrated in FIG. 5 has a curved shape (typically an arc shape) in plan view.

  By the way, the front edge portion 47 that is partially depressed as illustrated in FIG. 6 does not correspond to the convex shape because the point on the line segment S is not located on the elastic body 40. As can be understood from the above examples, the convex shape can also be referred to as a planar shape having no depression (concave portion), for example. Since the front edge portion 47 of the elastic body 40 of the first embodiment is formed in a planar shape that does not include local convex portions, the elastic body 40 is easily deformed so as to follow the bending and stretching of the knee portion P. Therefore, it is possible to reduce the burden when the user bends and stretches the knee P. In addition, there is an advantage that the possibility that distortion such as wrinkles and twisting occurs in the elastic body 40 when the knee P is bent and stretched can be reduced. However, it is also possible to employ the elastic body 40 having the shape illustrated in FIG.

  As described above, in the first embodiment, the plate-like elastic body 40 installed in the mounting portion 10 presses the knee portion P of the user in a plane. Therefore, it is possible to provide the supporter 1 with a good wearing feeling as compared with the configuration in which the user's body is locally pressed by the linear coil bone.

  In addition, in the supporter using the coil bone of patent document 1, the structure (henceforth "proportional 2") which formed the convex part of the thickness close | similar to the outer diameter of a coil bone around the coil bone can be assumed. According to the comparison 2, the side surface of the coil bone and the top surface of the convex portion have the same height (so-called flush), so that the user's body can be pressed in a plane. However, in contrast 2, there is a problem that the manufacturing cost increases because it is necessary to form convex portions around the coil bone. In contrast to the proportional 2, in the first embodiment, the elastic body 40 is plate-shaped and itself presses the user's body in a plane, so that a convex portion is formed around the elastic body 40. There is no need. Therefore, there is an advantage that the manufacturing cost can be reduced as compared with the comparative 2.

[Second Embodiment]
FIG. 7 is a plan view of the supporter 2 according to the second embodiment of the present invention, and FIG. 8 is a sectional view taken along line VIII-VIII in FIG. The supporter 2 of 2nd Embodiment is an auxiliary tool (corset) utilized for support of a user's waist | hip | lumbar part (illustration of a movable part). As illustrated in FIGS. 7 and 8, the supporter 2 of the second embodiment includes a mounting portion 60 that can be mounted on the waist.

  The mounting part 60 is formed of a flexible cloth like the mounting part 10 of the first embodiment. The wearing part 60 has a first surface F1 located on the opposite side to the user's body in the worn state, and a second surface F2 opposite to the first surface F1 (that is, the user's body side). As illustrated in FIG. 7, the mounting portion 60 of the second embodiment includes a base portion 61, a mounting portion 62 a, and a mounting portion 62 b. The attachment portion 62a continues on the negative side of the base portion 61 in the X direction, and the attachment portion 62b continues on the positive side of the base portion 61 in the X direction. The attachment portion 62a and the attachment portion 62b are detachable from each other. When the supporter 2 is mounted on the user's waist, the mounting portion 62a and the mounting portion 62b are coupled with the mounting portion 60 wound around the waist so that the second surface F2 faces the user's waist. Is done.

  As illustrated in FIGS. 7 and 8, the covering portion 70 is joined to the first surface F <b> 1 of the mounting portion 60. In FIG. 7, for convenience, the cover 70 is shaded. In the first embodiment, the mounting portion 10 is located on the opposite side (outside) from the body and the covering portion 30 is located on the body side (inside), whereas in the second embodiment, the mounting portion 60 is on the body side. The covering portion 70 is located on the opposite side (outside) from the body.

  The covering portion 70 is formed of, for example, a mesh-like cloth fabric (mesh). As illustrated in FIGS. 7 and 8, the mounting portion 60 is provided with an auxiliary portion 65 a, an auxiliary portion 65 b, and an auxiliary portion 65 c. The auxiliary part 65a is a long cloth cloth along the negative edge in the X direction of the covering part 70, and the auxiliary part 65c is a long shape along the positive edge of the covering part 70 in the X direction. Cloth fabric. The auxiliary portion 65b is a long cloth cloth that extends along the center line of the covering portion 70 between the auxiliary portion 65a and the auxiliary portion 65c. Similarly to the first embodiment, the peripheral edges on the positive side and the negative side in the Y direction of the covering unit 70 are sewn to the mounting unit 60 by peripheral sewing with respect to the mounting unit 60. Accordingly, a space R1 between the auxiliary portion 65a and the auxiliary portion 65b and a space R2 between the auxiliary portion 65b and the auxiliary portion 65c are formed.

  As illustrated in FIGS. 7 and 8, the elastic body 80a is accommodated in the space R1, and the elastic body 80b is accommodated in the space R2. In the mounted state, since the auxiliary portion 65b is located on the median plane of the user, the elastic body 80a and the elastic body 80b are located on the opposite sides of the median plane. In the following description, when it is not necessary to distinguish between the elastic body 80a and the elastic body 80b, they are collectively expressed as “elastic body 80”. The planar shape of the elastic body 80 of the second embodiment is trapezoidal.

  As illustrated in FIG. 8, the elastic body 80 includes a first member 81 and a second member 82 as in the first embodiment. Each of the first member 81 and the second member 82 is a plate-like member. The first member 81 and the second member 82 are installed in the mounting portion 60 in a stacked state. As understood from FIG. 8, the elastic body 80 is installed in the mounting portion 60 so that the first member 81 is positioned on the covering portion 70 side and the second member 82 is positioned on the mounting portion 60 side. Therefore, in the mounted state, the second member 82 is located on the waist side when viewed from the first member 81.

  The first member 81 and the second member 82 are formed of different materials. Specifically, as in the first embodiment, the first member 81 is a foam formed of a resin material such as EVA, and the second member 82 is formed of a resin material such as styrene-based elastomer. It is a low-resilience foam. The first member 81 and the second member 82 are different in hardness. Specifically, the second member 82 is softer than the first member 81. Therefore, the first member 81 supports the user's waist, and the second member 82 is deformed so as to follow the deformation of the waist.

  FIG. 9 is an explanatory diagram illustrating a supporter employing a hard member made of metal or the like as the support member 90 that supports the user's body as a comparison with the second embodiment. FIG. 9 shows how the support member 90 is deformed when the waist is bent. On the other hand, FIG. 10 is explanatory drawing of the state with which the elastic body 80 of 2nd Embodiment was mounted | worn to the waist | hip | lumbar part. Since the rigid support member 90 of FIG. 9 cannot appropriately follow the bending of the user's waist, a gap is generated between the support member 90 and the waist as illustrated in FIG. Only the part presses the waist locally. Therefore, the user may feel discomfort (for example, pain or discomfort). On the other hand, in the second embodiment, the soft second member 42 is located on the waist side when viewed from the first member 41. Therefore, as illustrated in FIG. 10, the waist is supported by the hard first member 41, while the second member 42 is deformed so as to follow deformation (for example, bending) of the waist. That is, the state in which the second member 42 presses the waist portion in a plane is maintained. As understood from the above description, according to the second embodiment, as in the first embodiment, it is possible to improve the wearing feeling while maintaining the performance of the supporter 2 supporting the user's waist. .

  In addition, the characteristic of the 1st member 81 is the same as that of the 1st member 41 of 1st Embodiment, and the characteristic of the 2nd member 82 is the same as that of the 2nd member 42 of 1st Embodiment. For example, the second member 82 is formed of a low-rebound foam having a rebound resilience (JIS K6301) of 20% or more and 60% or less (more preferably 30% or more and 50% or less). The condition of the 25% compression hardness H1 of the first member 81 is the same as the condition of the first member 41 of the first embodiment, and the condition of the 25% compression hardness H2 of the second member 82 is the first embodiment. The conditions of the second member 42 are the same. The configuration in which the thickness of the first member 81 is larger than the thickness of the second member 82 and the configuration in which the colors of the first member 81 and the second member 82 are different are the same as in the first embodiment. As described above, since the covering portion 70 is a mesh-like cloth fabric, the user can visually recognize the elastic body 80 (particularly the first member 81 located outside) via the covering portion 70.

  As illustrated in FIG. 7, an adjustment band 67 a and an adjustment band 67 b are installed in the mounting portion 60. Specifically, the base ends of the adjustment band 67a and the adjustment band 67b are joined to the auxiliary portion 65b. The leading ends of the adjustment band 67a and the adjustment band 67b can be coupled to any position on the first surface F1 of the mounting portion 60 by, for example, a planar fastener 68. In the above configuration, the degree to which the supporter 2 tightens the waist is adjusted by changing the positions of the tip portions of the adjustment band 67a and the adjustment band 67b in the state where the mounting part 60 is mounted on the waist of the user. Is possible.

  As described above, in the second embodiment, the plate-like elastic body 80 installed in the mounting part 60 presses the user's waist area. Therefore, it is possible to provide the supporter 2 with a good wearing feeling as in the first embodiment, as compared with the configuration in which the user's body is locally pressed by the linear coil bone.

[Modification]
Each form illustrated above can be variously modified. Specific modes of modifications that can be applied to the above-described embodiments are exemplified below. Two or more aspects arbitrarily selected from the following examples can be appropriately combined as long as they do not contradict each other.

(1) The planar shape of the elastic body (40, 80) is not limited to the examples of the above-described embodiments. For example, as illustrated in FIG. 11, the elastic body 40 having the front edge portion 47 having a polygonal shape can be used for the supporter 1 of the first embodiment. Assuming a point on the line segment S connecting any two points on the front edge 47 in FIG. 11, the front edge 47 in FIG. 11 is a convex where the point on the line C is located on the elastic body 40. Shape. In the supporter 1 using the elastic body 40 of FIG. 11, the peripheral edge B3 and the suture line L3 of the covering portion 30, and the peripheral edge B4 and the suture line L4 of the cover portion 30 are in front of the elastic body 40, as illustrated in FIG. A polygonal shape corresponding to the edge 47 is formed.

(2) The total number or shape of the notches 46 formed in the elastic body 40 of the first embodiment is not limited to the illustration of the first embodiment. For example, a configuration in which one notch 46 is formed in the rear edge 45 of the elastic body 40 or a configuration in which three or more notches 46 are formed in the rear edge 45 may be employed. It is also possible to omit the notch 46.

  In the first embodiment, the notch 46 having the same shape is formed at a common position in the first member 41 and the second member 42, but the notch 46 is provided only in one of the first member 41 and the second member 42. It is also possible to form. Further, the notch 46 may be formed at a different position between the first member 41 and the second member 42.

(3) The total number or shape of the through holes 16 formed in the mounting portion 10 of the first embodiment is not limited to the illustration of the first embodiment. For example, as illustrated in FIG. 13, a configuration in which eight through holes 16 are formed in a portion overlapping one elastic body 40 in the mounting portion 10, or 1 in the mounting portion 10 as illustrated in FIG. 14. A configuration in which four through holes 16 are formed in a portion overlapping the elastic bodies 40 can also be adopted. Further, as illustrated in FIG. 15, it is possible to form a through hole 16 parallel to the X direction. One or more through holes may be formed in the mounting portion 60 of the lower back supporter 2 exemplified in the second embodiment.

(4) The planar shape of the opening 15 formed in the mounting portion 10 in the first embodiment is arbitrary. For example, as illustrated in FIG. 16, a configuration in which a rectangular opening 15 having a corner having an arc shape is formed in the mounting portion 10, or an elliptical or oval opening as illustrated in FIG. 17. A configuration in which the portion 15 is formed in the mounting portion 10 can also be adopted.

(5) In the above-described embodiments, the configuration in which the first member (41, 81) and the second member (42, 82) are bonded with an adhesive is illustrated. However, the first member and the second member are mutually connected. It is not indispensable to be joined. For example, even when the first member and the second member are accommodated in the space (R1, R2) in an overlapped state without being joined to each other, the same effects as those of the above-described embodiments are realized.

(6) In each of the above-described embodiments, the elastic body (40, 80) including the first member and the second member has been exemplified, but the total number of members constituting the elastic body is not limited to the above examples (two). . For example, a configuration in which another member is interposed between the first member and the second member, or a configuration in which the first member is disposed between the second member and the other member may be employed.

(7) In the above-described embodiments, the configuration in which the two elastic bodies (40, 80) are installed is illustrated, but the number of elastic bodies is not limited to the above examples. For example, one elastic body 40 that overlaps one side surface (inner side surface or outer side surface) of the knee portion P can be installed in the mounting portion 10. Even in the configuration in which one elastic body 40 is installed, as in the first embodiment, the effect that a good wearing feeling can be realized and the effect that the manufacturing cost can be reduced as compared with the above-described contrast 2 are realized. The

(8) The part where the elastic bodies (40, 80) overlap in the user's body is not limited to the knee P and the waist. For example, the present invention can also be applied to an elbow supporter in which an elastic body that overlaps the user's elbow is installed in the mounting portion.

(9) In the first embodiment, the opening 15 is covered with the mesh-like covering portion 30 having air permeability, but the air permeability of the covering portion 30 is not essential. For example, it is possible to overlap the opening portion 15 with the covering portion 30 formed of a water-absorbing cloth fabric. Even in the configuration using the water-absorbing covering portion 30, the stuffiness in the space between the knee back portion Pb and the supporter 1 can be reduced.

(10) In each of the embodiments described above, the elastic body (40, 80) is configured by stacking the first member (41, 81) and the second member (42, 82), but the elastic body is formed of a plurality of members. Such a configuration may be omitted. That is, the elastic body can be constituted by a single elastic member formed in a plate shape.

(11) The shape of the mounting portion (10, 60) is not limited to the examples of the above-described embodiments. For example, the number of attachment portions 12 in the supporter 1 of the first embodiment is not limited to the illustration (four) in FIG. 1 and can be arbitrarily changed. Specifically, as illustrated in FIG. 18, three attachment portions 12 (12 a 1, 12 a 2, 12 a 3) are formed on the negative side of the base portion 11 in the X direction, and on the positive side of the base portion 11 in the X direction. It is also possible to form three attachment portions 12 (12b1, 12b2, 12b3). An attaching / detaching part 20a (planar fastener) is installed in the attaching part 12a1, an attaching / detaching part 20b is installed in the attaching part 12a2, and an attaching / detaching part 20c is installed in the attaching part 12a3. In the mounted state, the attachment portion 12a1 is connected to the attachment portion 12b1 by the attachment / detachment portion 20a, the attachment portion 12a2 is connected to the attachment portion 12b2 by the attachment / detachment portion 20b, and the attachment portion 12a3 is connected to the attachment portion 12b3 by the attachment / detachment portion 20c.

  The shape or size of the attachment portion 12 is not limited to the example shown in FIG. For example, as illustrated in FIG. 19, a configuration in which the lengths in the X direction of the attachment portions 12a1 and 12a2 are larger than the lengths in the X direction of the attachment portions 12b1 and 12b2 may be employed. Further, as illustrated in FIG. 20, a single attachment portion 12 b may be installed on the positive side in the X direction of the base body portion 11. The configuration in FIG. 20 can also be rephrased as a configuration in which a part of the base portion 11 is used as the attachment portion 12b.

  Moreover, although the supporter (1,2) of the structure which couple | bonds both ends after winding the planar mounting part (10,60) around a user's body was illustrated in the above description, a user's body The present invention can also be applied to a supporter having a cylindrical mounting portion into which the movable part is inserted, as in the above-described embodiments.

(12) In the first embodiment, the elastic body 40a and the elastic body 40b share the same structure (for example, shape or size) and characteristics (for example, material or hardness), but the elastic body 40a and the elastic body 40b have a structure. It is also possible to make the characteristics different. The configuration in which the elastic body 40a and the elastic body 40b share the same structure and characteristics (the first embodiment described above) is particularly suitable for the supporter 1 that is used for both the right knee and the left knee. On the other hand, the structure in which the elastic body 40a and the elastic body 40b have different structures and characteristics is particularly suitable for a supporter dedicated to the right knee or a supporter dedicated to the left knee.
