It is disposed at a position where the center line O1 intersects.

  Next, the manufacturing method of this elbow supporter is demonstrated. First, a tricot knitted long knitted body is formed using two types of yarns, nylon yarn and polyurethane yarn, and the long knitted body is cut into two rectangular shapes as shown in FIG. The sheet bodies 9a and 9b are manufactured.

  And the urethane type resin piece 2a is made to be scattered by apply | coating urethane type resin to the surface of one sheet body 9a of them by screen printing.

At the same time, the first medium strong tensile stress region 171, the second medium strong tensile stress region 172 a, 172 b, the third medium strong tensile stress region 173, the fourth medium strong tensile stress region 174 a, 174 b, the fifth A medium strong tensile stress region 175 and a sixth medium strong tensile stress region 176 are formed.

  Then, the other sheet body 9b is overlaid on the surface of the one sheet body 9a. Then, in this state, bonding is performed by applying a predetermined pressure for a predetermined time at a predetermined temperature with a press machine.

  As a result, the urethane-based resin pieces 2a in the first strong tensile stress region portions 131 and 132 to the fourth strong tensile stress region portion 160 and the urethanes in the first medium strong tensile stress region portion 171 to the sixth medium strong tensile stress region portion 176. The system resin piece 2a and the sheet bodies 9a and 9b are bonded to each other.

  In this state, the supporter body 1 is formed by the two sheet bodies 9a and 9b, and each of the first strong extension stress region portions 131 and 132 to the fourth strong extension stress region portion 160 is more than the supporter body 1. First strong extension stress portions 31 and 32 to fourth strong extension stress portions 6 having strong extension stress are formed. At the same time, each of the first medium strong tensile stress region 171 to the sixth medium strong tensile stress region 176 has a tensile stress stronger than that of the supporter body 1, and the first strong tensile stress portions 31, 32 to The first medium strong extension stress part 71 to the sixth medium strong extension stress part 76, whose extension stress is weaker than the four strong extension stress parts 6, are formed.

  Here, since the tensile test of each of the supporter main body, the strong tensile stress portion, and the medium strong tensile stress portion was performed, the measurement data is shown in FIG. In this test, the test piece was stretched by 20%, 50%, and 80% in the longitudinal direction (axial direction) and lateral direction (circumferential direction) for the supporter main body, the strong tensile stress portion, and the medium strong tensile stress portion, respectively. The tensile force (gf) at the time of the acquisition was acquired and compared. Further, a test piece having a width of 25 mm was used as a test piece, and measurement was performed under the conditions of a grip interval of 10.0 cm and a tensile speed of 5 cm / min.

  As a result, the strong extension stress portion required the largest extension force, and then the supporter main body extended with the smallest extension force in the medium extension stress portion. That is, the strong extension stress portion had the strongest extension stress, followed by the medium strength extension stress portion, and the supporter body had the weakest extension stress.

  In addition, since the extensibility test was conducted together with the tensile test, the result is also shown in FIG. This extensibility test was carried out by examining the elongation rate of each test piece with an extension force of 1 kgf, 1.5 kgf, and 2.25 kgf. The tensile speed at this time was measured under the condition of 30 cm / min.

  In addition, since the extensibility test was conducted together with the tensile test, the result is also shown in FIG. This extensibility test was carried out by examining the elongation rate of each test piece with an extension force of 1 kgf, 1.5 kgf, and 2.25 kgf. The pulling speed at this time was measured under the condition of 30 cm / min.

  Returning to FIG. 8, the description will be continued. After the supporter body 1 is formed by the two sheet bodies 9a and 9b as described above, the outer peripheral edge portion is cut. Thereby, the supporter for elbows of the unfolding state shown in FIG. 4 is obtained.

  Thereafter, as shown in FIG. 4, the positioning portion 8 is formed on the surface of the outer cylindrical body 1a constituted by the other sheet body 9b by applying paint such as paint ink. Then, for example, the right end pieces 74b provided at the left and right ends of the supporter body 1 are turned rearward, the left end pieces 74a are overlapped, and both are sewn together. In addition, in FIG. 2, the adhesion part after sewing is not represented.

  By the above, the cylindrical elbow supporter of this embodiment shown in FIGS. 1 to 3 can be obtained.

  Next, the operation of the elbow supporter will be described. When this elbow supporter is attached to the elbow of the right arm, for example, the front side of the elbow supporter is turned upside down so that the arm is passed through the arm slot 11 in this state.

  At this time, since the strong extension stress portion 2 is disposed at an interval in the circumferential direction of the supporter body 1, for example, the first side collateral ligament covering portion 31 and the second side collateral ligament covering portion 32 are continuously formed. Compared with the case where it is provided on the entire circumference, it is easier to expand the diameter, and the arm can be easily passed.

  Then, the elbow head is covered with the elbow head covering portion 83 partitioned by the elbow head partition display portion 81 of the positioning portion 8, and the left and right center point indicating portion 82 is visually aligned with the substantially left and right center of the elbow head.

  Thereby, for example, the first side collateral ligament covering portion 31 covers the outer side collateral ligament, and the second side collateral ligament covering portion 32 covers the outer side collateral ligament, respectively. Further, the first forearm muscle covering portion 72a covers a part of the ulnar carpal extensor and the heel side carpal extensor, and the second forearm muscle covering portion 72b is a part of the ulnar carpal flexor and the heel side carpal flexor. Coating.

  Therefore, when wearing on the elbow, for example, when the user does not know the position of the inner collateral ligament or outer collateral ligament of the elbow, or the first collateral ligament covering portion 31 and the second collateral ligament which are difficult to see Anyone can easily dispose the covering portion 32 and the first forearm muscle covering portion 72a at a predetermined position of the elbow portion, and can efficiently protect the ligament and muscle.

  From this state, for example, when the elbow part is moved to bend or stretch, the first side collateral ligament covering part 31 and the second side collateral ligament covering part 32 cover the ligament of the elbow part, so that the extension of the ligament is suppressed.
