(First embodiment of the present invention)

  1 and 2, the wrist joint supporter 10 is a sock knitting machine (for example, a knitting model “Lambda Anfiney (144 needles, cylinder diameter: 31/2 inch, 1 inch) manufactured by Murata Manufacturing Co., Ltd. No. of needles: 36 gauge))), and is a supporter that assists the wearer's wrist joint in close contact with the body surface of the wearer.

  1 and 2, the left-hand wrist joint supporter 10 is illustrated, but for the right-hand wrist joint supporter 10, the positions of the respective parts of the left-hand wrist joint supporter 10 are symmetrical positions. Since it is the same as the wrist joint supporter 10 for the left hand, the illustration is omitted.

  The wrist joint supporter 10 is for the base fabric portion 1 which is a knitted fabric formed by knitting a flat knitting, a rib knitting, a tuck knitting, a floating knitting, a pile knitting, etc. By applying different knitting, desired functionality such as a taping function is provided. In addition, the base fabric part 1 which concerns on this embodiment is a knitted fabric except the 1st anchor part 2, the 2nd anchor part 3, and the 1st support part 4 which are mentioned later among cylindrical knitted fabrics, 1x A knitted fabric knitted by one Kanoko (hereinafter referred to as a Kanoko knitted fabric).

  Kanoko knitted fabric means that flat knitting and tack (a structure that allows multiple loops to escape in subsequent courses without escaping stitches in a certain course) alternately or in several courses in the course direction and the wale direction. The knitted fabric that appears in For this reason, in the base fabric part 1, by using both the flat knitting and the tack, the surface of the knitted fabric can be raised and watermarked, and a mesh pattern like a Kanoko appears.

  The wrist joint supporter 10 is knitted around one end 10a of the tubular knitted fabric, and includes a first anchor portion 2 that fastens the wrist joint supporter 10 to the wearer's forearm.

The first anchor portion 2 is knitted such that the stretch resistance in the circumferential direction H of the wrist joint supporter 10 (tubular knitted fabric) is larger than the stretch resistance of the base fabric portion 1 in the circumferential direction H of the wrist joint supporter 10. . That is, the tension in the case where the material is not stretched is given a tension, and the tension of the base fabric portion 1 in the circumferential direction H of the wrist joint supporter 10 is _FH1, and the circumferential direction of the wrist joint supporter 10 When the tension of the first anchor portion 2 at _H is F _H2 , the first anchor portion 2 has a stronger tightening force in the circumferential direction H of the wrist joint supporter 10 than the base fabric portion 1. It has a magnitude relationship of F _H2 > F _H1 .

  As a specific knitted fabric, the first anchor portion 2 is formed by folding the sword knitted fabric to the inside of the wrist joint supporter 10 at one end 10a of the wrist joint supporter 10 and other yarn (for example, at the boundary with the base fabric portion 1). By using a double deer knitted fabric (hereinafter referred to as double deer knitted fabric) sewed with wooly nylon thread), the stretch resistance in the circumferential direction H of the wrist joint supporter 10 is reduced with respect to the base fabric portion 1. Can be bigger.

  Thus, the 1st anchor part 2 is knitted around the wearer's forearm, and the stretch resistance in the circumferential direction H of the wrist joint supporter 10 is the stretch resistance of the base fabric in the circumferential direction H of the wrist joint supporter 10. By being larger, the wrist joint supporter 10 can be fixed to the wearer's forearm, and positional displacement of the wrist joint supporter 10 during dorsiflexion (extension) and palmar flexion (bending) of the wrist joint can be suppressed. Further, the first anchor portion 2 is connected to a first support portion 4 to be described later, and also functions as an anchor of the first support portion 4.

  The wrist joint supporter 10 protrudes from one side of the other end 10b of the tubular knitted fabric, and a small tubular body into which the first finger (mother finger, thumb) 21 of the wearer's hand is inserted. And a second anchor portion 3 that goes around the portion corresponding to the proximal phalanx 21b of the first finger 21 (see FIG. 3A).

  The second anchor portion 3 according to this embodiment is a knitted fabric knitted by flat knitting (hereinafter referred to as a flat knitted fabric), and the edge of the flat knitted fabric is a micro tape 3a (very thin nylon yarn). And woven rubber woven with polyurethane) and sewed (binder).

  In addition, the second anchor portion 3 according to the present embodiment is cut by a tubular knitted fabric to be the wrist joint supporter 10 and the cut edge is folded back inside the tubular knitted fabric, and is sewn by a sewing machine. The tubular knitted fabric may be knitted by knitting without cutting. In particular, the sewing portion constituting the second anchor portion 3 uses a highly elastic sewing thread, increases the number of needles of the sewing machine, makes it a flexible bellows, and relieves the pressure applied to the wearer's first finger 21. It is preferable.

  The second anchor portion 3 positions the wrist joint supporter 10 with respect to the wearer's wrist joint by inserting the first finger 21 of the wearer's hand, and at the same time in the circumferential direction H of the wrist joint supporter 10. Rotational movement and parallel movement in the length direction L can be suppressed to prevent displacement. The second anchor portion 3 is connected to the first support portion 4 and functions as an anchor of the first support portion 4.

  Further, the wrist joint supporter 10 is knitted between the first anchor part 2 and the second anchor part 3 in the tubular knitted fabric, and is worn from the second anchor part 3 on the palm (palm) side of the wearer. It extends to the first anchor part 2 on the wearer's palm side through the portion corresponding to the bean-like bone 26 of the wearer via the back of the hand (back of hand) of the wearer, via the palm of the wearer's palm The first support portion 4 made of a spiral knitted fabric is provided.

Note that the first support portion 4 according to the present embodiment is knitted such that the stretch resistance in the length direction L of the wrist joint supporter 10 is larger than the stretch resistance of the base fabric portion 1 in the length direction L of the wrist joint supporter 10. ing. That is, the tension of the base fabric section 1 in the length direction L of the wrist supporter 10 and F _L1, a first tension of the support portion 4 in the length direction L of the wrist supporter 10 when the F _L4, the One support portion 4 has a magnitude relationship of F _L4 > F _L1 such that the support portion 4 has a stronger tightening force in the length direction L of the wrist joint supporter 10 than the base fabric portion 1.

Further, the first support portion 4 according to the present embodiment is knitted such that the stretch resistance in the length direction L of the wrist joint supporter 10 is larger than the stretch resistance in the circumferential direction H of the wrist joint supporter 10. That is, when the tension of the first support portion 4 in the circumferential direction H of the wrist joint supporter 10 is F _H4 , compared with the circumferential direction H of the wrist joint supporter 10, the longitudinal direction L of the wrist joint supporter 10 It has a magnitude relationship of F _L4 > F _H4 that has a strong tightening force.

  Specifically, the wrist supporter 10 is formed by making the first support portion 4 a knitted fabric using a 4 × 2 tack knitting and a spliced yarn knitting together (hereinafter referred to as a tuck knitting or a splicing knitted fabric). The expansion and contraction resistance in the length direction L of the wrist joint supporter 10 can be increased with respect to the circumferential direction H of the wrist joint supporter 10 in the length direction L of the wrist joint supporter 10 with respect to the base fabric portion 1 of the Kanoko knitted fabric. Expansion resistance can be increased.

  Here, the tucked knitted fabric is a knitted fabric that does not make a temporary stitch when knitting a fabric but creates a stitch together when the next course is knitted.

  In the tuck knitting and splicing yarn knitted fabric, in addition to the tuck knitting ground knitting yarn, other knitting yarn (for example, woolly nylon yarn) is added and fed, so that the length of the wrist joint supporter 10 in the length direction L is increased. Expansion and contraction of the first support portion 4 is moderately suppressed, and other knitting yarns are cut at the boundary between the first support portion 4 and the base fabric portion 1 (cut boss).

  Thus, the first support portion 4 has a stretch resistance in the length direction L of the wrist joint supporter 10 that is greater than the stretch resistance of the base fabric in the length direction L of the wrist joint supporter 10, and It is knitted spirally so that a force is generated in the direction in which one finger 21 is abducted. Thereby, the 1st support part 4 can carry out the abduction of the 1st finger | toe 21 of a hand unconsciously of a wearer, and can maintain in the state which opened the 1st finger | toe 21 with respect to the palm. Moreover, the 1st support part 4 restrict | limits a wearer's wrist joint's bending | flexion and a crookedness, can ensure the stability of a wrist joint, and reduces the load concerning the tendon located in a wrist joint. be able to.

  In particular, by wearing the wrist joint supporter 10 during basketball competition or practice, the first support portion 4 can move the wrist joint back and forth (dorsiflexion, palm flexion) and left and right motion (flexion, Ulnar carpal extensor 31 (see FIG. 3C) that suppresses the flexion and adduction of the wrist joint, and flexor carpal flexor 32 that flexes and abducts the wrist joint 3 (b)) and the action of the ulnar carpal flexor 33 (see FIG. 3 (c)) for palmar flexion and adduction of the wrist joint to reduce the accumulation of fatigue on the wearer. be able to.

  When the wrist joint supporter 10 completely covers the wearer's palm, the wearer handles the ball (particularly, basketball) through the knitted fabric of the wrist joint supporter 10, which has an adverse effect on ball control. In addition to hindering play during competition or practice, the knitted fabric may be damaged by friction with the ball.

  For this reason, the wrist joint supporter 10 according to the present embodiment inserts the second finger 22, the third finger 23, the fourth finger 24, and the fifth finger 25 of the wearer's hand, and the first finger 21, the second finger 25, and the like. Parts corresponding to the carpal joints 27 (see FIG. 3A) of the fingers 22, the third finger 23, the fourth finger 24, and the fifth finger 25, and the wearer's first metacarpal bone 21a and second middle A portion corresponding to the space between the hand bones 22a (see FIG. 3A) is provided, and an edge portion 5 serving as the other end 10b of the tubular knitted fabric is provided.

  Thereby, as shown to Fig.2 (a), the wrist joint supporter 10 provided with the edge part 5 will expose most of a wearer's palm, and the contact area with the ball | bowl in a wearer's hand part Can be ensured and does not hinder play during competition or practice, and damage to the wrist joint supporter 10 can be prevented.

  In addition, the edge part 5 which concerns on this embodiment has micro edge of the base fabric part 1 (Kanoko knitted fabric), the 2nd anchor part 3 (flat knitted fabric), and the 1st support part 4 (tuck knitted fabric). It is sandwiched and sewn with a tape (woven rubber woven with very thin nylon thread and polyurethane) (binder).

  In addition, the wrist joint supporter 10 according to the present embodiment has a wrist joint supporter 10 at the approximate center on the front (see FIG. 1 (a)) and back (see FIG. 1 (b)) side of the first anchor portion 2. A second support portion 2 a having a stretch resistance in the length direction L that is greater than a stretch resistance in the circumferential direction H of the wrist joint supporter 10 is provided. Further, the second support portion 2a has a stretching resistance in the length direction L of the wrist joint supporter 10 in the first anchor portion 2 (hereinafter referred to as other region 2b) excluding the second support portion 2a. The wrist joint supporter 10 is knitted larger than the expansion and contraction resistance in the length direction L.

That is, the tension of the second support portion 2a in the length direction L of the wrist supporter 10 and F _L2a, the tension of the second support portion 2a in the circumferential direction H of the wrist supporter 10 when the F _H2a, Compared with the circumferential direction H of the wrist joint supporter 10, there is a magnitude relationship of F _L2a > F _H2b that has a strong tightening force in the longitudinal direction L of the wrist joint supporter 10.
Further, when the tension of the other region 2b in the length direction L of the wrist joint supporter 10 is _FL2b , the second support portion 2a is compared with the other region 2b in the length direction of the wrist joint supporter 10. It has a magnitude relationship of F _L2a > F _L2b (F _L2 ) that has a strong tightening force on L.

  Specifically, as the second support portion 2a, a part of the deer knitted fabric on the outer side of the double stag knitted fabric of the first anchor portion 2 is used as a tuck knitting / split yarn knitted fabric. The stretch resistance in the length direction L of the wrist joint supporter 10 can be increased with respect to the circumferential direction H of the joint supporter 10, and the first anchor portion 2 (the other region 2b) of the double deer knitted fabric can be used. On the other hand, the expansion / contraction resistance in the length direction L of the wrist joint supporter 10 can be increased.

  As described above, the second support portion 2 a is knitted at the approximate center of the front and back sides of the first anchor portion 2, and the stretching resistance in the length direction L of the wrist joint supporter 10 is the circumferential direction of the wrist joint supporter 10. The stretch resistance in the length direction L of the wrist joint supporter 10 is larger than the stretch resistance in the length direction L of the wrist joint supporter 10 in the first anchor portion 2 (other region 2b). . Thereby, the 2nd support part 2a limits the dorsiflexion and palm flexion of a wearer's wrist joint, can ensure the stability of a wrist joint, and reduces the load concerning the tendon located in a wrist joint. can do.

  In particular, by wearing the wrist joint supporter 10 during a basketball game or practice, the second support portion 2a can be used from the ball keeping accompanied by the dorsiflexion of the wrist joint to the shooting involving the palm flexion of the wrist joint (return of the wrist). The wrist flexor and short flexor extensor muscles 35 (Fig. 3 (Fig. 3 (3) c)), and the action of the ulnar carpal flexor 33 (see FIG. 3 (c)) for palm flexion and adduction of the wrist joint, can reduce the accumulation of fatigue on the wearer. .

  When the second support portion 2a crosses the first anchor portion 2 in the length direction L of the wrist joint supporter 10, the tightening force by the second support portion 2a becomes too strong, and the palm joint is bent and There is a risk of braking the dorsiflexion more than necessary. For this reason, the 2nd support part 2a which concerns on this embodiment arrange | positions the area | region extended along the circumferential direction H of the wrist joint supporter 10 in parallel, and the movable range of palm flexion and dorsiflexion of a wrist joint I am trying to adjust.

  In the present embodiment, as the base knitting yarn used for the Kanoko knitting, the tuck knitting, and the flat knitting, the yarn count is 30 /-, and a blended yarn made of cotton and polyester (for example, “Rich” manufactured by MIYAMA CORPORATION "House"), a two-ply surface yarn, a yarn count of 30/75, a back yarn that is a processed yarn (FTY: Filament Twisted Yarn) with a polyurethane elastic yarn as a shaft, A rubber yarn which is a covering yarn (for example, “ST6700” manufactured by Operontex Co., Ltd.) in which a polyester winding yarn is wound around a polyurethane core yarn is used, but is not limited to this material.

  For example, as the surface yarn, cotton, hair (cashmere, lamb, angora, etc.), natural fibers such as silk or hemp, chemical fibers such as acrylic, or materials with sweat-absorbing, quick-drying or body temperature adjustment functions, etc. It is preferable to select according to the cost of the supporter 10 or the needs of the wearer. Further, as the back yarn, it is preferable to select an antibacterial, deodorizing or deodorizing material according to the cost of the wrist joint supporter 10 or the needs of the wearer.

  Further, the woolly nylon yarn (pattern yarn) in the tuck knitting / addition yarn knitted fabric (the first support portion 4 and the second support portion 2a) is composed of two knitting yarns having a yarn count of 100/2.

Next, a verification test for verifying the function and effect of the wrist joint supporter 10 according to the present embodiment will be described with reference to FIGS.
In the verification test, the right hand wrist joint supporter 10 was worn on the right hand of two subjects (healthy males, no history of limbs) (hereinafter referred to as wearing) and not worn (hereinafter referred to as non-wearing). The basketball dribbling motion and shooting motion were performed, and the angle trajectory due to wrist joint flexion and palm flexion and flexion and scale flexion was measured by three-dimensional motion analysis.

  For the three-dimensional motion analysis, a three-dimensional motion analysis system “VICON MX” manufactured by VICON was used.

  In FIG. 4, the horizontal axis indicates the ratio (percentage) [%] of each protrusion time to the predetermined number of protrusion times (dribble time: 100%), and the vertical axis indicates the wrist joint associated with the dribbling motion. The angle [°] is shown, with the rib as the reference axis (0 °), the positive region is the dorsiflexion of the wrist joint, and the negative region is the palmar flexion of the wrist joint.

  In FIG. 4 (a), the nine dribbling motions are measured twice when worn (solid line shown in FIG. 4 (a)), and measured once when not worn (broken line shown in FIG. 4 (a)). ) Shows the results. Moreover, in FIG.4 (b), the dribbling operation | movement of 9 protrusions is measured 3 times at the time of wearing (the solid line shown in FIG.4 (b)), and measured twice when not wearing (the broken line shown in FIG.4 (b)) ) Shows the results.

  As shown in FIG. 4, the wrist joint supporter 10 is worn when worn because the amplitude of the vibration waveform is small compared to the case when not worn and the waveform is symmetric with respect to the center of vibration. By doing so, it can be seen that the dorsiflexion and palm flexion of the wrist joint are suppressed, the unnecessary movement of the wrist in the dribbling motion is reduced, and the wrist joint is operated efficiently.

  In FIG. 5, the horizontal axis indicates the ratio (percentage) [%] of each protrusion time to the predetermined number of protrusion times (dribble time: 100%), and the vertical axis indicates the wrist joint accompanying the dribbling motion. The angle [°] is shown, with the center line of the forearm being the reference axis (0 °), the positive region is the flexion of the wrist joint, and the negative region is the crook of the wrist joint.

  Further, in FIG. 5 (a), nine dribbling operations are measured twice when worn (solid line shown in FIG. 5 (a)) and measured once when not worn (broken line shown in FIG. 5 (a)). ) Shows the results. Further, in FIG. 5 (b), 18 dribbling operations are measured three times when worn (solid line shown in FIG. 5 (b)) and measured twice when not worn (broken line shown in FIG. 5 (b)). ) Shows the results.

  As shown in FIG. 5, when worn, the waveform approaches a symmetrical waveform with respect to the center of vibration compared to when not worn, and particularly when the subject 2 shown in FIG. In this case, the amplitude of the vibration waveform is remarkably small as compared with the case where the subject 2 is not wearing it. For this reason, by wearing the wrist joint supporter 10, bending of the wrist joint and fluctuation of the crook are suppressed, the useless movement of the wrist in the dribbling operation is reduced, and the wrist joint is efficiently operated. I understand that.

  In FIG. 6, the horizontal axis indicates the ratio (percentage) [%] of the elapsed time to one shot time (100%), and the vertical axis indicates the angle [°] of the wrist joint accompanying the shooting operation. With the rib as the reference axis (0 °), the positive region is the dorsiflexion of the wrist joint, and the negative region is the palmar flexion of the wrist joint.

  Moreover, in Fig.6 (a), the chute | shoot operation | movement was measured once at the time of wearing (solid line shown in FIG. 6 (a)), and the result of having measured twice (when shown by the broken line shown in FIG. 6 (a)) at the time of non-wearing. Show. Moreover, in FIG.6 (b), the chute | shoot operation | movement was measured twice at the time of wearing (the solid line shown in FIG.6 (b)), and the result of having measured once at the time of non-wearing (dashed line shown in FIG.6 (b)) is shown. Show.

  As shown in FIG. 6, when wearing, since a remarkable change is not seen compared with the case when not wearing, wearing the wrist joint supporter 10 makes the dorsiflexion of the wrist joint during the chute operation. In addition, the same shooting force as when not worn can be maintained without hindering palm flexion.

  In FIG. 7, the horizontal axis indicates the ratio (percentage) [%] of the elapsed time to one shot time (100%), and the vertical axis indicates the angle [°] of the wrist joint accompanying the shooting operation. With the center line of the forearm as the reference axis (0 °), the positive region is the flexion of the wrist joint, and the negative region is the flexion of the wrist joint.

  Moreover, in Fig.7 (a), the chute | shoot operation | movement is measured once at the time of wearing (the solid line shown in Fig.7 (a)), and the result of having measured twice at the time of non-wearing (dashed line shown in Fig.7 (a)) is shown. Show. Moreover, in FIG.7 (b), the chute | shoot operation | movement was measured twice at the time of wearing (the solid line shown in FIG.7 (b)), and the result of having measured once at the time of non-wearing (dashed line shown in FIG.7 (b)) is shown. Show.

  As shown in FIG. 7, the maximum displacement of the angle in the positive region and the negative region with respect to the angle in the initial state (0%) is smaller in the case of wearing compared to the case of non-wearing. By wearing the wrist joint supporter 10, the wrist joint is restrained from bending and shaking, reducing the useless movement of the left and right wrists in the shooting operation, and allowing the wrist joint to act efficiently. Recognize.
