Such a supporter is formed of a stretchable material and is in close contact with the joint, and a hole is formed at a position corresponding to the kneecap of the joint so that the supporter does not deviate from the joint part with bending and stretching movement of the attached joint part. There is something that has been.

In particular, the supporter that strongly protects and holds the joint is further formed in a band shape and is provided with a hook-and-loop fastener at the end. The surface fastener of the other end is adhered and fixed to the surface of the supporter. Accordingly, the joint can be appropriately protected and held regardless of the size of the joint of the wearer. There exists a thing of patent document 1 as such a supporter.
JP 2003-166107 A

  In the supporter described in Patent Document 1, although the position corresponding to the kneecap is covered by the supporter body, the supporter body is entirely composed of the same material (FIG. 1 of Patent Document 1). However, such a supporter may have the following problems.

  For example, the knee is bent during walking or flexing / extending, and in that case, the knee covers the corner of the outer part of the joint when it is bent. For this reason, when a low stretchable material is used as a supporter at a position covering the kneecap, the protrusion of the kneecap is suppressed, which makes it difficult to bend and stretch the knee.

  On the other hand, if a material with high elasticity is used in consideration of the difficulty of bending and stretching, the tightening force of the joint part becomes weak, so the joint part cannot be held firmly, and while being used In some cases, it is not possible to maintain proper wearing such as a supporter sliding down. Such a problem can occur not only in the knee but also in other joints such as the elbow. Here, the material having high elasticity means that the material is stretched with a smaller force, and the same applies to this embodiment.

  In view of the above points, an object of the present invention is to provide a joint supporter capable of protecting a joint while ensuring the bendability of the joint.

Hereinafter, an embodiment of a knee joint supporter (hereinafter simply referred to as “knee supporter”) embodying the present invention will be described.
FIG. 1 is a front view of the knee supporter S in a developed state. This knee supporter S is a left / right combination that can be worn on either the left or right foot. FIG. 1 shows a state in which the knee supporter S is deployed. The knee supporter S has a substantially belt-like shape as a whole, and is roughly divided into three parts in the longitudinal direction (left-right direction in the figure). From the left side in FIG. 1, a first member 1 disposed at one end, a second member 2 attached to the first member 1, and a second member 2 attached to the second member 2 and disposed at the other end. Three members 3 are obtained.

  The first member 1 and the third member 3 are arranged on the left and right with the second member 2 as the center, and are attached and integrated. In the knee supporter S shown in FIG. 1, the first member 1, the second member 2, and the third member 3 are integrally attached and the outer peripheral ends thereof are covered with piping tape (not shown).

  The first member 1 has a polyurethane foam sheet as a base material, and a knitted fabric N (for example, tricot fabric) using elastic yarn is bonded to one surface thereof, and a loop surface that is a female die of a surface fastener is bonded to the other surface. A material having a three-layer structure in which the formed pile fabric P is bonded is used. The first member 1 is arranged so that the knitted fabric N of this material is the front (the side shown in FIG. 1) and the pile fabric P is the back (the side shown in FIG. 2).

  The first member 1 is used to fix the knee supporter S by adhering to the front surface of the third member 3 to be described later when the knee supporter S is mounted. As shown in FIG. Are formed with two arm portions 4 and 5 that are substantially parallel to each other and a groove portion 6 therebetween, and the first member 1 has a U-shape when viewed from the front. The groove portion 6 formed between the arm portions 4 and 5 has a length (depth) substantially half of the left and right length of the first member 1, and the width of the groove portion 6 is the upper and lower arm portions 4 and 5. However, the width of the groove 6 becomes wider toward the end (left side in the figure). That is, the width of the arm portions 4 and 5 formed above and below the groove portion 6 gradually decreases toward the distal end side (left side in FIG. 1) of the first member 1.

  FIG. 2 is a rear view of the knee supporter S, and the first member 1 that is located on the left side in FIG. 1 and is opposite to that in FIG. 1 is located on the right side in FIG. Fixing members 4a and 5a formed with a hook surface that is a male hook-and-loop fastener are sewn to the tips of the arm portions 4 and 5 on the back side of the first member 1. The fixing members 4a and 5a have a circular shape on the tip side, and a part of the circular shape projects from the tips of the arm portions 4 and 5 of the first member 1, respectively. 5 (FIGS. 1 and 2).

  The 2nd member 2 is arrange | positioned so that the base end side (right side of FIG. 1) of the 1st member 1 may be followed. The second member 2 is formed such that both the part attached to the first member 1 and the part attached to the third member 3 bulge outward from the upper and lower ends toward the central part. The upper side of the two member 2 is formed slightly longer than the lower side, and the second member 2 itself is formed in a trapezoidal shape. Due to the difference in length between the upper piece and the lower piece of the second member 2, the knee supporter S as a whole has a curved shape with both ends slightly curved downward (FIGS. 1 and 2).

  The second member 2 is formed of a mesh fabric having high stretchability and excellent air permeability, and is thinner than the first member 1. In addition, when the knee supporter S is worn, the second member 2 is positioned corresponding to the back of the knee (popliteal surface) that is the inner side of the joint.

  Further, a third member 3 is disposed continuously to the second member 2. This third member is a member that abuts on the outer part of the knee joint and protects the same part, and is formed into a substantially rectangular shape as a whole by arranging three belt-like fabrics arranged in three upper and lower tiers. Yes. Of the three fabrics constituting the third member 3, the upper fabric 7 arranged in the upper stage and the lower fabric 8 arranged in the lower stage are the same materials as those used for the first member 1. That is, a knitted fabric N using a polyurethane foam sheet as a base material and using elastic yarn is bonded to one surface thereof, and a pile fabric P having a loop surface that is a female die of a surface fastener is bonded to the other surface 3 It is a material consisting of a layer structure. However, when used for the third member 3, the first member 1 is arranged upside down and a loop surface is formed in which the front side (the side shown in the front in FIG. 1) is a female type of surface fastener. The pile fabric P side and the back side (the side shown in the front in FIG. 2) are the knitted fabric N side using elastic yarn.

  In addition, fixing members 7a and 8a each having a hook surface that is a male hook fastener are sewn to the front end portions of the upper fabric 7 and the lower fabric 8 respectively. Since the fixing members 7a and 8a are for temporarily fixing the first member 1 to the third member 3, they are made of the same material as the fixing members 4a and 5a attached to the arm of the first member 1. A small area is sufficient.

  The middle fabric 9 disposed between the upper fabric 7 and the lower fabric 8 is disposed at a portion of the outer portion of the knee joint that comes into contact with the kneecap, which is a corner when bent. This middle fabric 9 is a material formed by adhering a flat knitted fabric made of covered yarn using polyurethane elastic yarns on both the front and back sides of a polyurethane foam sheet, and is more elastic than the upper fabric 7 and the lower fabric 8. Is expensive. Further, no loop is formed on the surface of the middle fabric 9 so that it does not adhere to the fixing members 4a and 5a. A through-hole 10 that penetrates through the front and back of the middle-stage fabric 9 is formed at a substantially central portion of the middle-stage fabric 9. Note that the upper and lower widths of the middle fabric 9 are slightly shorter than the diameter (upper and lower length) of the kneecap at the portion where the through hole 10 is formed.

  On the other hand, a cover 11 is disposed on the back side of the third member 3 so as to cover the through-hole 10 formed in the middle fabric 9, and a pad 12 is further disposed on the back side thereof. The outer peripheral portion with 12 is attached to the third member 3.

  The cover 11 is a material formed by flat knitting covered yarn using polyurethane elastic yarn, and has extremely high stretchability. When the knee supporter S is mounted, the cover 11 prevents a portion of the kneecap from being exposed from the through hole and suppresses the movement of the patella inside the knee by contacting the kneecap. At the same time, the through hole 10 is prevented from spreading (elongating) when the knee supporter S is used or repeatedly used. Therefore, the cover 11 is attached to the third member 3 with a certain amount of tension applied thereto, and the cover 11 acts in a direction in which the cover 11 is always contracted, that is, a direction in which the through hole 10 is contracted.

  As shown in FIG. 2 and FIG. 3 (cross-sectional view taken along line AA in FIG. 1), the pad 12 is composed of an O-shaped base 13 and a U-shaped protective pad 14 disposed so as to overlap therewith. Yes. The base 13 is made of the same material as that of the middle fabric 9, and a long hole 15 is formed at the center. The long hole 15 is formed in an elliptical shape whose upper and lower axes are long axes, and the left and right short axes are formed to have a diameter larger than at least the through hole 10 of the middle cloth 9. The base 13 is disposed on the third member 3 such that the center of the long hole 15 is substantially the same position as the center of the through hole 10. Therefore, the through hole 10 formed in the middle fabric 9 is located inside the long hole 15 in plan view.

  The long hole 15 may be of a size that allows at least a part of the kneecap to be fitted and held in the long hole 15 when the knee supporter S of the present embodiment is mounted, and is large enough to securely fit the entire kneecap. It doesn't have to be.

  Further, the protective pad 14 is formed in a U-shape that is substantially the same shape as the lower half of the base 13, and presses the patella inside the patella by pressing the lower periphery of the patella inserted in the long hole 15, It suppresses movement of the patella (particularly downward movement) when the wearer is bent and stretched. Accordingly, the material of the protective pad 14 is not particularly limited, but it is necessary to have a thickness that can hold the patella from the lower side. For example, the patella can be formed by gradually increasing the thickness from the upper side to the lower side. Can be held from below. Note that the cover 11 and the pad 12 are attached to the third member 3 by attaching the cover 11 and the pad 12 together in a state where a certain amount of tension is applied to the cover 11 and then attaching them to the third member 3. Just attach it to the back side and sew it around with a sewing machine.

Next, the mounting method of the knee supporter S of this embodiment will be described.
Since the knee supporter S of the present embodiment shown in FIGS. 1 and 2 is used for both left and right and may be worn on either foot, a method of wearing on one foot will be described. When the knee supporter S is worn while the wearer is seated on a chair, the lower body becomes stable and the hand can easily reach the knee, which makes it easy to wear. Also, when worn, the knee may be stretched or slightly bent.

  First, the knee supporter S is applied to the knee so that the wearer's kneecap fits into the through hole 10 of the third member 3 (FIG. 4A). Even if the kneecap is not exactly located at the position where the kneecap is inserted into the through-hole 10, if the elongated hole 15 of the pad 12 is made to correspond to the position of the kneecap, the distal end of the kneecap is inserted into the middle cloth through the elongated hole 15. The positions correspond to the nine through holes 10. As a result, the third member 3 is positioned with respect to the patella and the periphery of the patella is pressed against the pad 12 by the same state, and the movement is suppressed. In particular, the patella is held from the lower side by the protective pad 14, and below the patella. Will be suppressed.

With the third member 3 aligned, hold the end of the third member 3 with one hand (for example, the left hand) and fix it so that the position of the long hole 15 with respect to the kneecap does not shift, with the other hand (right hand). While grasping one or both of the arm portions 4 and 5 of the first member 1 and applying tension to the entire knee supporter S (while pulling), the arm 1 is wound around the knee, and the knee is substantially rotated. This state is shown in FIG. For convenience of explanation, only the knee supporter S is shown, and the illustration of the hand is omitted.
Then, while further pulling the first member 1, the first member 1 is guided to a position where the back surface of the first member 1 is superimposed on the front surface of the third member 3. In this way, when the knee supporter S is made to make a round around the knee, the second member 2 naturally becomes a position corresponding to the popliteal cavity that is the back of the knee. And if the 1st member 1 is located in the front of the 3rd member 3 by making a circuit around the knee, the fixed member 7a attached to the 3rd member 3 by lightly pressing the 1st member 1 against the 3rd member 3 8a adheres to the back surface (pile fabric P) of the first member 1 and the knee supporter S is temporarily fixed.

  After the temporary fixing, the fixing members 4a and 5a attached to the tips of the arm portions 4 and 5 of the first member 1 are attached to the third member 1 while holding the arms 4 and 5 of the first member 1 and applying tension. Press against the front of the member 3. In the third member 3, the upper fabric 7 and the lower fabric 8 are respectively located corresponding to the fixing members 4 a and 5 a of the arm portions 4 and 5, and these surfaces are pile fabrics P. Therefore, the first member 1 and the 3rd member 3 are adhere | attached, and the knee supporter S is fixed completely. Since the arm portions 4 and 5 are respectively bonded to the upper fabric 7 and the lower fabric 8 of the third member 3, the middle fabric 9 of the third member 3 is not covered from above (FIG. 4 (c)). .

  In the knee supporter S mounted by the above-described method, the middle fabric 9 having higher elasticity is disposed at the portion in contact with the kneecap, and the upper fabric 7 and the lower fabric 8 are disposed above and below the kneecap. For this reason, even if the knee is bent while the knee supporter S is worn, the middle fabric 9 having high stretchability of the third member 3 covering the kneecap mainly stretches and does not hinder the knee from bending and stretching. On the other hand, since the upper fabric 7 and the lower fabric 8 firmly hold and hold the upper and lower knee caps, the knee supporter S will not be displaced by bending or stretching or walking.

  Furthermore, the second member 2 which is a thin mesh fabric is disposed at a position corresponding to the popliteal surface which is the back surface of the kneecap. Since the second member 2 is a thin mesh fabric, the knee is bent. It is not bulky and does not hinder walking. Further, when the knee is bent, the kneecap is pressed by the middle fabric 9, the cover 11, and the pad 12, so that when the knee is stretched again, the pressing force acting on the kneecap is an assist. Makes it easier to stretch your knees.

According to the knee supporter S of the above embodiment, the following effects can be obtained.
In the above embodiment, a material having higher elasticity than the upper fabric 7 and the lower fabric 8 is applied to the middle fabric 9 that is disposed corresponding to the kneecap that becomes the corner when bent among the third members 3 that directly contact the knee. Used. For this reason, when the knee supporter S is mounted, the upper fabric 7 and the lower fabric 8 securely hold the entire knee so that the knee supporter S is not easily displaced. Since the middle stage fabric 9 having high properties mainly stretches, the movement of the knee joint is not hindered.

  In addition, by mounting the kneecap so that a part of the kneecap fits into the through hole 10 formed in the middle fabric 9, the through hole 10 is enlarged when the knee is bent, and the patella is held by the middle fabric 9. Complement the extension of the middle fabric 9 until.

  The upper and lower widths of the middle fabric 9 are formed shorter than the diameter of the kneecap. Since the middle fabric 9 does not have to extend when the knee is bent to prevent the movement of the knee, it is not necessary to completely cover the entire kneecap, and it is sufficient to cover at least the corners of the joint. For this reason, the vertical width of the entire supporter can be shortened, and a compact supporter as a whole can be obtained.

  Furthermore, since the first member 1 overlaid on the third member 3 has a U-shape, the first member 1 is overlaid so as to avoid the middle fabric 9 that expands and contracts. For this reason, the expansion and contraction of the middle stage fabric 9 is not hindered by the first member 1.

  In the third member 3, a cover 11 that covers the through hole 10 is attached to the back side of the through hole 10. Therefore, a part of the kneecap is not exposed in the exposed state through the through-hole 10, and the appearance when the knee supporter S is worn becomes natural. Further, the movement of the patella can be suppressed by the cover 11 pressing the patella inside the knee. Furthermore, since the cover 11 is attached to the third member 3 with a certain amount of tension applied, the cover 11 acts to constantly contract the through hole 10, and the through hole 10 is enlarged when the knee supporter S is used or repeatedly used. Can be prevented.

A pad 12 is further attached to the back side of the third member 3. For this reason, when the knee supporter S is mounted, the periphery of the patella can be pressed and held so as not to move.
The pad 12 is configured by attaching a U-shaped protective pad 14 on an O-shaped base 13. Accordingly, the patella is held particularly from the lower side, and the downward movement of the patella can be suppressed.

  The upper fabric 7 and the lower fabric 8 of the third member 3 are pile fabrics P whose entire front surface is a female mold with a hook-and-loop fastener. Therefore, when the fixing members 4a and 5a attached to the first member 1 are fixed to the third member, the degree of freedom of the attachment position is increased, and fine adjustment at the time of mounting is facilitated.

  Further, fixing members 7a and 8a are respectively attached to the end portions of the upper fabric 7 and the lower fabric 8 of the third member 3, and are bonded to the pile fabric P on the back side of the first member 1 for temporary fixing. Is called. Therefore, once the first member 1 is temporarily fixed to the third member 3, the fixing members 4 a and 5 a of the first member 1 may be bonded to the third member 3 to be securely attached.

  The second member 2 corresponding to the popliteal fossa of the back of the knee is formed of a thin mesh fabric and is not bulky. Therefore, even when the knee is bent, the second member 2 contacting the popliteal is not disturbed and hinders walking. Absent.

  Fixing members 4 a and 5 a are attached in a state of protruding from the tips of the arm portions 4 and 5 of the first member 1. For this reason, if the protruding portion is gripped and pulled by hand, the entire knee supporter S is pulled, and the knee supporter S can be easily mounted.

  The long hole 15 of the pad 12 attached to the back surface thereof is larger than the through hole 10 formed in the middle fabric 9 of the first member 1. For this reason, positioning of the kneecap at the time of wearing of the knee supporter S is easy.

  The middle fabric 9 and the cover 11 of the third member 3 are formed of a highly stretchable fabric. When the knee is bent, the entire knee supporter S has some elastic force in the contracting direction (the direction in which the knee is stretched). For example, when the wearer stands up from a bent state, the elastic force becomes an auxiliary force. The rising operation becomes easy.

  The same material is used for the upper fabric 7 and the lower fabric 8 of the first member 1 and the third member 3, and the first member 1 and the third member 3 are used with their front and back reversed. For this reason, it is possible to simultaneously obtain a change in appearance by switching the front and back of the same material and reducing the cost by using a common material.

The above embodiment may be modified as follows.
The knee supporter has been described, but the present invention can also be applied to a supporter that is attached to another joint. For example, it can be used for a supporter attached to an elbow joint, a hand (wrist) joint, a finger joint, a hip joint, or the like.

  Although the belt-like supporter has been described in the above embodiment, the stretchability of the material of the portion covering the kneecap and the material above and below the supporter that is not limited to the belt shape and is formed in a cylindrical shape in advance may be different.

  In the above embodiment, the bonding method using the hook-and-loop fastener has been described. However, it is not essential to attach the fixing members 4a, 5a, 7a, and 8a to both the first member 1 and the third member 3, and at least one of them may be used. Moreover, not only a hook-and-loop fastener but a thing fixed with a string etc. may be used.

  In the above embodiment, the through hole 10 formed in the middle fabric 9 may be omitted. It is sufficient to use a material having higher elasticity than the upper and lower sides at least at the corner (the kneecap) when the knee joint is bent.

In the above embodiment, the middle fabric 9 is arranged in the center of the third member 3 so that the stretchability is enhanced over the entire left and right regions of the third member 3, but the fabric having a high stretchability is at least around the kneecap. It is only necessary that the third member 3 is disposed on the left and right regions of the third member 3. Accordingly, as shown in FIG. 5 (a), the upper fabric 7 and the lower fabric 8 of the third member 3 are made of a single common fabric, and the portion that contacts the kneecap is cut out, and the shape corresponding to this cut-out portion It is also possible to sew together by providing a middle fabric 9 having a high stretchability. In the knee supporter S shown in the figure, illustration of the through hole 10, the cover 11, and the back pad 12 shown in the above embodiment is omitted for the sake of convenience.

  The main body of the knee supporter S is composed of a single fabric 21 having a high elasticity equivalent to the middle fabric 9 and is relatively higher than the middle fabric 9 like the upper fabric 7 and the lower fabric 8 of the third member 3 of the present embodiment. Regions 17 and 18 that have been processed to reduce the stretchability of the fabric 21 may be provided at locations where the stretchability is desired to be lowered (the same location is illustrated as two locations in the figure) (FIG. 5). (B)). This also causes a difference in stretchability between the kneecap portion and the upper and lower portions thereof, so that the object of the present invention can be achieved, and it is not necessary to prepare many fabrics. As a processing method for forming the regions 17 and 18 that can lower the stretchability of the fabric, for example, a fabric having low stretchability is stretched over the body of the knee supporter S, or the stretchability is desired to be lowered. There are rubber prints and resin prints.

  As shown in FIG. 5B, when the surface fastener is used as the fixing members 4a and 5a, it is necessary to provide the surface fastener at the portion where the fixing members 4a and 5a adhere to each other at the time of mounting. , 18 on the back side of the knee supporter S, or, for example, if it is resin or rubber, it is necessary to print it linearly so as not to inhibit the adhesion of the fixing members 4a and 5a. In addition, in the same figure, the through-hole 10, the cover 11, and the back pad 12 are not shown in the same manner as in FIG.

In addition to the use of materials having different stretchability as described in the present embodiment, processing that makes the stretchability of the fabric different may be used in combination.
In the above embodiment, a foamed polyurethane sheet or a knitted fabric is used as a material used for the knee supporter S in consideration of stretchability. However, the material is not limited to this as long as it has a desired stretchability. For example, a rubber sheet is used. May be.
