Description

  The present invention relates to a knee supporter mounted on a knee of a body.

Conventionally, for example, supporters have been widely used for fixing, supporting, compressing, or keeping warm the knee and elbow of the body. As such a supporter, there is one proposed in Patent Document 1, for example. This supporter has a core material having a modulus larger than that of the elastic material forming the main body on a part of the surface of the main body (supporter main body) made of the elastic material formed in a cylindrical shape, and the elongation of the core material. A reinforcing material formed by laminating a surface material that restricts the above is adhered, and the modulus of the reinforcing material is set to a size that can restrict the movement of the affected area within the range of motion. As a result, in normal daily living conditions with little changes in muscles and ligaments, the body structure can be followed only by changes, and when the movement is intense, the elasticity of the reinforcing material is added due to the change in the body only and strong. Stress acts to suppress further muscle and ligament movement.

  Next, the third strong extension stress portion 23 of the strong extension stress portion 2 will be described. The third strong tensile stress portion 23 is mainly for preventing the supporter body 1 from sliding up after being mounted on the knee 100. As shown in FIG. 2, the axial direction on the rear surface side of the supporter body 1 is provided. Is disposed in a strip shape at a position closer to the leg opening 12 side.

  Next, the medium strong tensile stress portion 3 will be described. As shown in FIGS. 1 and 2, the medium strong tensile stress portion 3 includes a first medium strong tensile stress portion 31 to a fourth medium strong tensile stress portion 34 in this embodiment. The first medium strong tensile stress portion 31 suppresses the lifting and displacement of the first strong tensile stress portion 21 from the knee, and appropriately protects and fixes the ligament and its vicinity of the knee 100 and the tendon and its vicinity.

These outer peripheral adjacent portion dividing portions. The outer peripheral adjacent portion 31a and the inner peripheral adjacent portion 31b are divided into a plurality of adjacent portion small pieces by the inner peripheral adjacent portion dividing portion 43b.

  The outer peripheral adjacent portion dividing portion 43a and the inner peripheral adjacent portion dividing portion 43b are connected to the narrow divided portion 41a and the wide divided portion 41b, respectively, which have divided the first strong extension stress portion 21.

  Specifically, the narrow divided portion 41a is connected to the outer peripheral adjacent portion dividing portion 43a on the outer diameter side and to the inner peripheral adjacent portion dividing portion 43b on the inner diameter side. Thus, one continuous slit-shaped dividing portion is formed by the narrow dividing portion 41a, the outer peripheral adjacent portion dividing portion 43a, and the inner peripheral adjacent portion dividing portion 43b.

  The wide divided portion 41b is connected to the outer peripheral adjacent portion dividing portion 43a on the outer diameter side and is connected to the inner peripheral adjacent portion dividing portion 43b on the inner diameter side. In this embodiment, in the wide dividing portion 41b, the outer peripheral adjacent portion 31a extends to the inner peripheral adjacent portion 31b and is connected to the inner peripheral adjacent portion 31b.

  The outer peripheral adjacent portion 31a and the inner peripheral adjacent portion 31b have the same structure. Therefore, only the outer periphery adjacent portion 31a will be described below.

  The outer peripheral adjacent portion 31a is formed in substantially the same manner as the first strong extension stress portion 21. However, as shown in FIG. 7, the outer peripheral adjacent portion 31 a includes both the interspersed portions 23 where the urethane resin pieces 2 a are scattered and the non-spotted portions 24 where the urethane resin pieces 2 a are not scattered. The urethane resin pieces 2a are interspersed so that the area ratio is about 3: 7.

  In this way, by making the area ratio of the interspersed portion 23 to the non-spotted portion 24 in the outer peripheral adjacent portion 31a smaller than the area ratio in the first strong tensile stress portion 21, the outer peripheral adjacent portion 31a The extension stress is stronger than that of the supporter body 1 but is weaker than the extension stress of the first strong extension stress portion 21.

  Next, the second medium strong tensile stress portion 32 will be described. The second medium strong tensile stress portion 32 is disposed on the circumferential direction side of the first strong tensile stress portion 21 and the second strong tensile stress portion 22 on the rear surface side of the supporter body 1, and the first medium strong tensile stress. The portion 31 is connected to the outer peripheral adjacent portion 31a.

  The second medium strong tensile stress portion 32 has the same structure as the outer peripheral adjacent portion 31a of the first medium strong tensile stress portion 31 (see FIGS. 6 and 7). The following third medium strong tensile stress portion 33 and fourth medium strong tensile stress portion 34 also have the same structure as the outer peripheral adjacent portion 31a.

  The third medium strong tensile stress portion 33 and the fourth medium strong tensile stress portion 34 are for mainly preventing displacement in the axial direction after mounting. As shown in FIG. 2, the support body 1 is disposed on the front side of the leg insertion port 11 in the axial direction. On the other hand, the fourth middle strong tensile stress portion 34 is disposed over the entire circumference on the leg opening 12 side in the axial direction of the supporter body 1.

  Next, the manufacturing method of this knee 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.

  Then, urethane-based resin pieces 2a (shown in FIGS. 5 and 7) are dotted on the surface of one of the sheet bodies 9a by screen printing, and the first strong extension stress region 121 and the second strong extension are provided. Stress region 122, third strong tensile stress region 123, first medium strong tensile stress region 131, second medium strong tensile stress region 132, third medium strong tensile stress region 133, and fourth medium strong tensile stress A region portion 134 is formed.

  Next, 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 resin pieces 2a of the first strong tensile stress region portion 121 to the third strong tensile stress region portion 123 and the urethane resin of the first medium strong tensile stress region portion 131 to the fourth medium strong tensile stress region portion 134. The piece 2a is bonded to the sheet bodies 9a and 9b.

  In this state, the outer cylindrical body 1a and the inner cylindrical body 1b constituting the supporter body 1 are formed by the two sheet bodies 9a and 9b, and the first strong extension stress region portion 121 to the third strong strength are formed. In each of the extension stress region portions 123, the first strong extension stress portion 21 to the third strong extension stress portion 23, which have stronger extension stress than the supporter body 1, are formed.

  At the same time, each of the first medium strong tensile stress region portion 131 to the fourth medium strong tensile stress region portion 134 has a tensile stress stronger than that of the supporter body 1, and the first strong tensile stress portion 21 to the third strong strength. The first medium strong extension stress part 31 to the fourth medium strong extension stress part 34 whose extension stress is weaker than the extension stress part 23 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.

  Returning to FIG. 8, the description will be continued. After forming the first strong tensile stress portion 21 and the like with the two sheet bodies 9a and 9b as described above, the outer peripheral edge portion is cut. In this embodiment, it cuts into two pieces, the front piece which comprises the front surface etc. of a supporter, and the rear piece which comprises the rear surface etc. of a supporter. Thereafter, as shown in FIG. 1, the positioning portion 8 is formed on the surface of the outer cylindrical body 1a constituted by the other sheet body 9b by applying a paint such as paint ink.

  As shown in FIGS. 1 to 3, the left and right ends of the front piece and the rear piece are overlapped and sewn together to form a supporter body 1, and a flat rubber prepared in advance in the supporter body 1. The part 10a can be sewn. Thereby, the supporter of this embodiment can be obtained. By the above, the cylindrical knee supporter of this embodiment shown in FIGS. 1-3 can be obtained. In FIG. 1 and FIG. 2, the sewn portion after sewing is not shown.

  Next, the operation of the knee supporter will be described. When this knee supporter is attached to the knee part of the body, the leg is passed through the leg insertion opening 11 with the positioning part 6 of the knee supporter facing forward. At that time, the first strong tensile stress portion 21 and the second strong tensile stress portion 22 are disposed in a portion from the front surface side to the left and right side surfaces, and the second medium strong tensile stress portion 32 is disposed on the rear surface side. Therefore, for example, the diameter can be easily increased compared to the case where the strong extension stress portion is provided on the entire circumference, and the leg can be easily passed.

  Then, the patella covering portion 63 formed by the patella covering portion section display portion 61 of the positioning portion 6 is visually matched with the patella of the knee portion, and the left and right center point indicating portion 62 is visually positioned substantially at the left and right center of the patella. Match.

  Thereby, the strong extension stress part 2 and the medium strong extension stress part 3 can be disposed at predetermined positions of the knee. For example, the first strong extension stress part 21 of the strong extension stress part 2 is provided with the patella tendon 101, the medial side accessory The ligament 102, the outer collateral ligament 103, the quadriceps tendon 104 (see FIG. 10), the outer vastus muscle and the inner vastus muscle of the quadriceps femoris can be covered.

  Therefore, even if the strong tensile stress portions 21 and 22 and the medium strong tensile stress portions 31 to 35 are difficult to see in appearance, anyone can easily arrange them at predetermined positions on the knee portion, and can be easily used. It is possible to appropriately protect and fix the knee ligament and its vicinity and the tendon and its vicinity.

  When the knee is moved from this state, the first strong extension stress portion 21 covers the main tendon and ligament of the knee, so that even when excessive force is applied to the knee, for example, Excessive elongation can be suppressed, and there is little risk of damaging tendons and ligaments.

  At this time, the first strong tensile stress portion 21 is lifted from the knee portion by the first intermediate strong stress portion 31 disposed on the entire circumference of the first strong tensile stress portion 21, and a gap is formed between the first strong tensile stress portion 21 and the knee portion. Or displacement from a tendon or ligament can be suppressed.

  In addition, since the first strong tensile stress portion 21 and the first medium strong tensile stress portion 31 are provided with the dividing portions, the first strong tensile stress portion 21 and the first medium strong tensile stress portion 31 are moved in the movement of the knee. It can follow and can move a knee part smoothly, and can further suppress the floating of the 1st strong extension stress part 21 from a knee part, or position shift from a tendon or a ligament of a knee part.

  In addition, the second strong tensile stress portion 22 can more reliably prevent the first strong tensile stress portion 21 from being lifted from the knee portion or displaced from the tendon or ligament, and can also be used for movement of the knee portion. It is possible to eliminate the feeling of tension of the first strong extension stress portion 21 when following, and to eliminate the uncomfortable feeling when the first strong stress portion 21 is attached.

  Furthermore, the second medium strong tensile stress portion 32 always pulls the first strong tensile stress portion 21 from both sides in the circumferential direction along with the movement of the knee portion, and further from the knee portion of the first strong tensile stress portion 21. Can be prevented from rising, or from being displaced from tendons and ligaments.

  Further, even if the first strong extension stress portion 21 is displaced from the tendon or ligament, the tendon or ligament is attached by one or both of the first medium extension stress portion 31 and the second strong extension stress portion 22. It can cover and can efficiently protect and fix tendons and ligaments.

  In the above embodiment, the first strong extension stress portion 21 is formed in a ring shape so as to cover the patella tendon 101, the medial collateral ligament 102, the lateral collateral ligament 103, the quadriceps tendon 104, and the like.
