As shown in FIG. 1, the supporter 11 in this embodiment is mounted on a knee part as a joint part of the body in a deployed state where the support part 11 is deployed in a cylindrical shape, and plays a role of protecting the knee part. The supporter main body 12 that exhibits the knee protection function is formed of a knitted fabric as an elastic fabric. The knitted fabric of the present embodiment is a circular knitted fabric made of polyurethane fiber and cotton, and the supporter body 12 is in close contact with the knee due to its stretchability. Further, the knitted fabric forming the supporter body 12 is seamless, and the supporter body 12 has a so-called seamless structure. A central portion on the surface side of the supporter body 12 is a kneecap abutting portion 13 indicated by a two-dot chain line in FIG. 1. The kneecap abutting portion 13 abuts on the kneecap and the supporter body 12 as a joint covering portion. So that the knee and the upper and lower sides thereof are covered. In the upper end portion of the surface of the supporter body 12, a horizontally long rectangular surface long hole 14 as a long hole is opened so as to extend in the horizontal direction. On the other hand, a back long hole 15 as a lower long hole is opened at the lower end of the back surface of the supporter body 12 so as to extend in the lateral direction.

  As shown in FIG. 2, the supporter 11 can be deformed from a deployed state to a folded state in which the supporter 11 is folded into a long rectangular plate shape when not attached to the joint site. Here, the folded state refers to a state where the supporter body 12 is folded without applying tension to both sides of the supporter body 12 with the center of the kneecap abutment 13 as a reference. In this folded supporter 11, the fabric on the kneecap abutting portion 13 side is called a surface fabric 16 and the fabric on the back surface overlapping the surface fabric 16 is called a back fabric 17 with the folds on both sides as boundaries.

  The surface long hole 14 is provided through the upper end portion of the surface fabric 16, and the surface long hole 14 is opened to extend in the width direction of the surface fabric 16 in the folded state. The long surface hole 14 is provided above the kneecap abutting portion 13 and in the vicinity of the upper opening 18. Specifically, the length D1 from the upper end of the supporter body 12 to the upper end of the long surface hole 14 is preferably shorter than the length D2 from the upper end of the supporter body 12 to the upper and lower centers of the supporter body 12. The length D1 is more preferably shorter than the length D3 from the lower end of the long surface hole 14 to the upper and lower centers of the supporter body 12. And the surface long hole 14 is comprised so that it may be located above a kneecap at the time of mounting | wearing, and the stretchability of the surface fabric 16 in the vicinity of the upper opening part 18 is adjusted with this surface long hole 14. FIG.

  The lateral opening width of the surface long hole 14 is preferably formed to be less than half the length of the circumference of the stretchable fabric at that portion. In other words, the length L1 in the longitudinal direction of the surface long hole 14 is preferably shorter than the full width W1 of the supporter body 12 at the portion where the surface long hole 14 is formed, and shorter than the full width W1. In addition, it is preferably longer than half of the full width W1.

  The back long hole 15 is provided in the lower end portion of the back fabric 17 and opens in the folded state so as to extend in the width direction of the back fabric 17. Further, the back long hole 15 is provided below the kneecap abutting portion 13 and in the vicinity of the lower opening 19. Specifically, the length D4 from the lower end of the supporter body 12 to the lower end of the back surface long hole 15 is preferably shorter than the length D5 from the lower end of the supporter body 12 to the center of the supporter body 12. The length D4 is more preferably shorter than the length D6 from the upper end of the back surface long hole 15 to the center of the supporter body 12. And the back surface long hole 15 is configured to be positioned on the back side of the knee part below the kneecap (the upper part of the calf shin) at the time of wearing, and the back surface cloth 17 is stretchable in the vicinity of the lower opening 19 by the back surface long hole 15. Has been adjusted.

  The lateral opening width of the back long hole 15 is preferably formed to be less than half of the length of the circumference of the stretchable fabric at that portion. In other words, the length L2 in the longitudinal direction of the back surface long hole 15 is preferably shorter than the full width W2 of the support body 12 at the portion where the long surface hole 14 is formed, and in addition to being shorter than the full width W2. More preferably, it is longer than half of the total width W2. Further, the length L2 of the back surface long hole 15 is formed shorter than the length L1 of the surface long hole 14, and is configured to fit an upper part of the inflated shin that is narrower than the upper part of the kneecap.

  A string rubber (not shown) is sewn to the surface long hole opening 20 which is the opening of the surface long hole 14 and the back long hole opening 21 which is the opening of the back long hole 15 by stitches. These string rubbers are respectively provided on the inner edges of the front long hole opening 20 and the back long hole opening 21, respectively, and the inner edges of the front long hole opening 20 and the back long hole opening 21 are reinforced and threaded. Fraying is prevented. These string rubbers have the same or higher stretchability as the surface fabric 16 and the back fabric 17, respectively, thereby limiting the stretchability of the front long hole opening 20 and the back long hole opening 21. It is difficult and can be fully demonstrated.

  Further, a covering fabric 22 as a highly stretchable fabric is sewn to the front long hole opening 20 and the back long hole opening 21, respectively, and the front long hole 14 and the back long hole 15 are respectively covered by the covering fabric 22. It has come to be. The coated fabric 22 is applied with a fabric having higher stretchability than the front fabric 16 and the back fabric 17 (particularly, high stretchability in the vertical direction), so that the stretchability of the front fabric 16 is sufficiently exhibited. It is like that. Specific examples of the covering fabric 22 include a two-weight ricott fabric and a jersey fabric.

  Now, in order to use this supporter 11, it mounts | wears so that the kneecap contact part 13 may be located in the kneecap which is the front side of the patella 23, as shown in FIG. At this time, the front oblong hole 14 is mounted above the kneecap, and the back oblong hole 15 is mounted so as to be positioned on the back side of the knee below the kneecap. Subsequently, as shown in FIG. 4, the kneecap is protruded and the surface fabric 16 is stretched in the vertical direction as the knee joint is bent. Since the surface fabric 16 can be expanded and contracted, a force for contracting acts on the surface fabric 16, and a force acts in a direction in which the upper opening 18 is shifted down by the contraction force. At this time, a long surface hole 14 is provided in the supporter body 12, and the long surface hole 14 is opened so as to extend in the width direction of the supporter body 12. When the knee joint is bent, the surface oblong hole 14 is expanded (opened) in the length direction of the supporter body 12, that is, in the vertical direction of the supporter body 12 due to the stretchability of the surface oblong hole opening 20. And the surface long hole 14 is deform | transformed into the elliptical shape by which the center part was expanded, and extending | stretching of the surface fabric 16 is reduced. Accordingly, the contraction force of the surface fabric 16 is relaxed, and the upper opening 18 is prevented from shifting downward.

  On the other hand, when shifting from the bent state of the knee joint shown in FIG. 4 to the extended state of the knee joint shown in FIG. 3, the back fabric 17 is stretched in the vertical direction, particularly during walking or jogging. At this time, the backer long hole 15 is provided in the supporter main body 12, and the back long hole 15 expands in the vertical direction of the supporter main body 12 as the knee joint extends. Therefore, since the shrinkage force of the back surface fabric 17 is relieved, the lower opening 19 is suppressed from shifting upward.

  Further, the upper and lower opening edges of the supporter body 12 are bent and stitched. And the front surface cloth 16 and the back surface cloth 17 in the upper and lower opening edges are constituted in a double manner, and the upper and lower opening edges are prevented from being displaced during mounting.

The effects exhibited by this embodiment will be described below.

When configured in this manner, the surface long hole 14 is enlarged in the vertical direction when the knee joint is bent, and the contraction force of the surface fabric 16 is relaxed. Therefore, the upper opening 18 is prevented from shifting downward when the supporter 11 is mounted. Moreover, since it is not necessary to adjust an inner peripheral size with members, such as a hook-and-loop fastener, at the time of mounting | wearing, it can mount | wear easily.

  Furthermore, since the surface long hole 14 can be formed in the surface fabric 16 by a normal punching process, the supporter 11 of the present embodiment can be easily manufactured. In addition, the supporter 11 according to the present embodiment does not need to fasten the supporter 11 to the knee portion by a member such as a hook-and-loop fastener, and the supporter 11 is attached by the stretchability of the fabric, so that the supporter 11 has a good fit. be able to. Moreover, since the long surface hole 14 does not inhibit the stretchability of the kneecap contact portion 13 when the knee joint is bent, the surface long hole 14 can sufficiently exhibit the function of protecting the knee portion.

  In the supporter 11 of this embodiment, a back long hole 15 is provided at the lower end portion of the back fabric 17. When configured in this manner, the back surface long hole 15 is enlarged in the vertical direction as the knee joint extends, and the contraction force of the back surface fabric 17 is alleviated. Therefore, since the lower opening 19 is suppressed from shifting upward, the shift at the time of mounting can be further suppressed. Further, even when the supporter 11 is mounted upside down, the back long hole 15 can play the role of the front long hole 14, so that the shift can be suppressed regardless of the mounting direction of the supporter 11. It becomes.

  In the folded state, when the length L1 is longer than the full width W1, the strength and shape stability of the upper opening 18 may be reduced. In the supporter 11 of this embodiment, the lateral opening width of the surface long hole 14 is formed to be less than half of the length of the circumference of the stretchable fabric at the portion where the surface long hole 14 is formed. Is preferred. In other words, the length L1 of the surface oblong hole 14 is preferably formed to be shorter than the full width W1. When comprised in this way, the shift | offset | difference of the supporter 11 can be suppressed in the state which maintained the intensity | strength and shape stability of the supporter 11 fully.

  In the folded state, when the length L1 of the surface oblong hole 14 is shorter than half of the full width W1, the effect of suppressing the displacement of the upper opening 18 may not be sufficiently exhibited. In the supporter 11 of this embodiment, in addition to being shorter than the full width W1, it is preferable that it is longer than half of the full width W1. When comprised in this way, the shift | offset | difference of the upper opening part 18 can be suppressed further.

  In the supporter 11 of this embodiment, the front long hole 14 and the back long hole 15 are covered with the covering fabric 22. When comprised in this way, since it is prevented that skin is exposed from the surface long hole 14 and the back surface long hole 15, the heat retention performance of the supporter 11 can be improved. In addition, when the garment is worn on the supporter 11, the skin exposed from the front long hole 14 and the back long hole 15 is prevented from being directly rubbed against the garment as the knee joint bends and stretches. Therefore, the wearing feeling of the supporter 11 can be improved.
