Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Unless otherwise specified, the same or corresponding parts in the following drawings are denoted by the same reference numerals, and the description thereof will not be repeated.

[0010] (Embodiment 1) Referring to FIGS. 1 to 3, the configuration of the tights 1 for rotational movement according to Embodiment 1 will be described. In all the following drawings, a state where the tights 1 for rotational movement are worn on the lower body of the wearer 100 is shown. The tights 1 for rotational movement are for assisting the rotational movement of the lower body of the wearer 100. Examples of the rotational movement of the lower body of the wearer 100 include swing movements such as golf and baseball.

[0011] The tights 1 for rotational movement includes a main body part 10 and a tightening part 20. The main body part 10 is configured to be wearable on the lower body 110 of the wearer 100. The main body part 10 has elasticity. That is, the main body part 10 is configured to be stretchable. The main body part 10 is made of an elastic fabric.

[0012] As the fabric of the main body part 10, an elastic material having elasticity, such as a normal clothing fabric such as a woven fabric or a knitted fabric, can be used. The fiber forming the elastic material is not particularly limited. For example, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate can be used. Also, as the fiber forming the elastic material, for example, polyurethane fibers, polyamide fibers, acetate fibers, cotton fibers, rayon fibers, ethylene vinyl alcohol fibers, nylon fibers, etc. can be used. The fabric of the main body part 10 is not particularly limited, but for example, the basis weight is 120 g / m 2 to 380 g / m 2 The following range is preferable, and 160 g / m 2 to 340 g / m 2 The following range is more preferable. Within the above range, there are advantages that the exercise function is not impaired, the durability is good, and it is light and easy to move. When the elongation rate of the fabric at a certain load (14.7 N) is measured using the JIS L 1096A method, the elongation rate of the main body part 10 is 100% or more and 350% or less, preferably 150% or more and 250% or less.

[0013] When the main body part 10 is worn on the lower body 110 of the wearer 100, the main body part 10 is configured to stretch more than the state before the main body part 10 is worn on the lower body 110 of the wearer 100. When the main body part 10 is worn on the lower body 110 of the wearer 100, the main body part 10 is configured to be difficult to change its position with respect to the lower body 110 of the wearer 100. That is, when a rotational movement is performed in the state where the main body part 10 is worn on the lower body 110 of the wearer 100, the main body part 10 is configured to be difficult to shift with respect to the lower body 110 of the wearer 100.

[0014] The tightening portion 20 is attached to the main body portion 10. The tightening portion 20 may be connected to the main body portion 10 by sewing or by heat bonding. The tightening portion 20 has greater elasticity than the main body portion 10. The tightening portion 20 is configured to tighten the lower body 110 of the wearer 100. The tightening portion 20 is constructed as a single unit. In other words, the tightening portion 20 as a whole is made up of interconnected individual parts.

[0015] The material of the fastening portion 20 is not particularly limited, and for example, a woven or knitted fabric containing polyurethane elastic fibers can be used. The polyurethane elastic fibers may be heat-fusible. The woven or knitted fabric may be mold-formed. In addition to polyurethane elastic fibers, the woven or knitted fabric may also contain nylon fibers. The material of the fastening portion 20 is not particularly limited, but for example, a fabric with a basis weight of 70 g / m 2 More than 400g / m 2 The following is preferable. A two-layer laminated fabric can also be used, which is made by laminating an elastic film sheet onto one side of the knitted fabric to create a two-layer structure. The film sheet used for lamination is an elastic thermoplastic elastomer such as a polyurethane elastomer or a polystyrene elastomer. When the elongation rate of the fabric is measured under a constant load (14.7N) using the JIS L 1096A method, the elongation rate of the tightened portion 20 is 3% to 60%, preferably 5% to 20%.

[0016] The fastening portion 20 is positioned on at least one of the wearer's right lower body 111 and left lower body 112 when the main body 10 is attached to the wearer's lower body 110. In this embodiment, the fastening portion 20 is positioned on both the wearer's right lower body 111 and left lower body 112 when the main body 10 is attached to the wearer's lower body 110.

[0017] The tightening portion 20 is spirally configured to sequentially cover the gluteus maximus, posterior greater trochanter, biceps femoris, posterior joint space, and tibial tuberosity of the wearer 100 in at least one of the right lower body 111 and the left lower body 112. In this embodiment, the tightening portion 20 is spirally configured to sequentially cover the gluteus maximus, posterior greater trochanter, biceps femoris, posterior joint space, and tibial tuberosity of the wearer 100 in both the right lower body 111 and the left lower body 112.

[0018] Specifically, the tightening portion 20 extends diagonally from the gluteus maximus of the wearer 100, passing posterior (posterior side) of the greater trochanter and along the lateral side of the biceps femoris, and from the posterior (posterior side) of the joint space, it extends diagonally across the tibial tuberosity from lateral to medial. The tightening portion 20 is positioned on the lateral side of the wearer 100's thigh, and not on the medial side of the wearer 100's thigh. The tightening portion 20 covers the tibial tuberosity of the wearer 100, but does not cover the patella of the wearer 100.

[0019] The tightening portion 20 includes a gluteus maximus portion 22 that covers the gluteus maximus of the wearer 100 and a biceps femoris portion 23 that covers the biceps femoris of the wearer 100. The elastic force of the gluteus maximus portion 22 is equal to or greater than that of the biceps femoris portion 23. The width of the gluteus maximus portion 22 is equal to or greater than that of the biceps femoris portion 23. The width of the gluteus maximus portion 22 is the width in the direction perpendicular to the direction in which the gluteus maximus portion 22 extends. The width of the biceps femoris portion 23 is the width in the direction perpendicular to the direction in which the biceps femoris portion 23 extends. The gluteus maximus portion 22 is more proximal (closer to the trunk) than the biceps femoris portion 23, and the gluteus maximus portion 22 has a larger muscle width than the biceps femoris portion 23. A greater proximal elastic force results in less discomfort, and a larger area is preferable for positioning in accordance with the muscle fibers. The biceps femoris portion 23 is positioned between the anchor portion 21 and the gluteus maximus portion 22. In this embodiment, the gluteus maximus portion 22 is positioned to straddle the left and right gluteus maximus muscles of the wearer 100.

[0020] The tightening portion 20 includes an anchor portion 21. The anchor portion 21 covers the tibial tuberosity obliquely from the outside to the inside. In this embodiment, the anchor portion 21 covers the tibial tuberosity obliquely from the outside to the inside, approaching the ankle. The anchor portion 21 is configured to suppress displacement of the tightening portion 20. The anchor portion 21 functions particularly as an anchor at the bottom of the tightening portion 20.

[0021] Referring to Figures 4 and 5, the state of the rotational movement tights 1 when the wearer 100 performs a rotational movement of the lower body 110 will be described. In this embodiment, the state of the rotational movement tights 1 when the wearer 100 performs a golf swing will be described. The description will focus on the case where the wearer 100 is a right-handed golfer.

[0022] As shown in Figure 4, when transitioning from the backswing (take-back), the elastic force generated by the stretching of the tightening part 20 located on the right lower body 111 of the wearer 100 provides an assisting force to the right lower body 111, suppressing internal rotation of the wearer 100's right hip joint until just before the transition. When transitioning from the backswing (take-back), immediately after the transition, the elastic force generated by the contraction of the tightening part 20 located on the right lower body 111 of the wearer 100 provides an assisting force to the right lower body 111, assisting external rotation of the wearer 100's right hip joint.

[0023] As shown in Figure 5, during the downswing (from the transition to impact), the elastic force generated by the stretching of the tightening portion 20 located on the left lower body 112 of the wearer 100 helps to accelerate the rotation of the upper body by decelerating the twisting of the wearer's waist, thereby suppressing the internal rotation of the wearer's left hip joint.

[0024] Next, a modified example of the rotational movement tights 1 according to Embodiment 1 will be described. Referring to Figures 6 and 7, in Modification 1 of the rotational movement tights 1 according to Embodiment 1, the tightening portion 20 is spirally arranged to sequentially cover the gluteus maximus, posterior greater trochanter, biceps femoris, posterior joint space, and tibial tuberosity of the wearer 100 on the right lower body 111 of the wearer 100. In other words, the tightening portion 20 is located on the right lower body 111 of the wearer 100 and is not located on the left lower body 112 of the wearer 100.

[0025] Referring to Figures 8 and 9, in Modification 2 of the rotational movement tights 1 according to Embodiment 1, the tightening portion 20 is spirally arranged on the left lower body 112 so as to sequentially cover the gluteus maximus, posterior greater trochanter, biceps femoris, posterior joint space, and tibial tuberosity of the wearer 100. In other words, the tightening portion 20 is located on the left lower body 112 of the wearer 100 and is not located on the right lower body 111 of the wearer 100.

[0026] Next, the effects and benefits of the rotational movement tights 1 according to Embodiment 1 will be described. According to the rotational movement tights 1 of Embodiment 1, the tightening portion 20 is spirally configured to sequentially cover the gluteus maximus, posterior greater trochanter, biceps femoris, posterior joint space, and tibial tuberosity of the wearer 100 in at least one of the right lower body 111 and the left lower body 112. Therefore, the elastic force of the tightening portion 20 covering the right lower body 111 can assist the rotational movement of the wearer 100's right lower body 111, and the elastic force of the tightening portion 20 covering the left lower body 112 can assist the rotational movement of the wearer 100's left lower body 112. Thus, the tightening portion 20 can assist the rotational movement of the wearer 100's lower body 110.

[0027] Furthermore, the anchor portion 21 covers the tibial tuberosity diagonally from the outside to the inside. If the anchor portion 21 were to cover the wearer's lower leg directly laterally, the wearer 100 may feel pain due to the tightening of the anchor portion 21. In this embodiment, the anchor portion 21 covers the tibial tuberosity, which is less likely to feel pain due to tightening. Therefore, it is possible to suppress the wearer 100 from feeling pain due to the tightening of the anchor portion 21. Moreover, the anchor portion 21 covers the tibial tuberosity diagonally from the outside to the inside. Therefore, the area of ​​the anchor portion 21 can be increased compared to the case where the anchor portion 21 covers the lower leg directly laterally, and the tightening force per unit area of ​​the anchor portion 21 can be reduced. This makes it possible to suppress the wearer 100 from feeling pain due to the tightening of the anchor portion 21. Thus, the stress on the wearer 100 caused by the anchor portion 21 can be reduced.

[0028] In the rotational exercise tights 1 according to Embodiment 1, the elastic force of the gluteus maximus portion 22 is equal to or greater than that of the biceps femoris portion 23. The gluteus maximus portion 22 is more proximal (closer to the trunk) than the biceps femoris portion 23. Since greater proximal elastic force reduces discomfort, the discomfort when wearing the rotational exercise tights 1 can be reduced.

[0029] In the rotational movement tights 1 according to Embodiment 1, the width of the gluteus maximus portion 22 is equal to or greater than the width of the biceps femoris portion 23. The gluteus maximus portion 22 has a larger muscle width than the biceps femoris portion 23. A larger area of ​​the gluteus maximus portion 22 is more preferable in order to position it in accordance with the muscle fibers. This allows the gluteus maximus portion 22 to be positioned in accordance with the muscle fibers of the gluteus maximus.

[0030] Furthermore, in Modification 1 of the rotational movement tights 1 according to Embodiment 1, the tightening portion 20 is positioned on the right lower body 111 of the wearer 100, and not on the left lower body 112 of the wearer 100. Depending on the wearer 100, rotational movement of the right lower body 111 may be difficult, but in Modification 1 of the rotational movement tights 1 according to Embodiment 1, the rotational movement of the right lower body 111 of the wearer 100 can be intensively assisted, thereby effectively improving the rotational movement of the right lower body 111 of the wearer 100.

[0031] Furthermore, in Modification 2 of the rotational movement tights 1 according to Embodiment 1, the tightening portion 20 is positioned on the left lower body 112 of the wearer 100, but not on the right lower body 111 of the wearer 100. Depending on the wearer 100, rotational movement of the left lower body 112 may be difficult, but in Modification 2 of the rotational movement tights 1 according to Embodiment 1, the rotational movement of the left lower body 112 of the wearer 100 can be intensively assisted, thereby effectively improving the rotational movement of the left lower body 112 of the wearer 100.

[0032] (Embodiment 2) The rotational movement tights 2 according to Embodiment 2 have the same configuration and effects as the rotational movement tights 1 according to Embodiment 1, unless otherwise specified.

[0033] Referring to Figures 10 and 11, the rotational movement tights 2 according to Embodiment 2 differ from the rotational movement tights 1 according to Embodiment 1 in that the tightening portion 20 extends mainly to the ankle of the wearer 100.

[0034] In the rotational movement tights 2 according to Embodiment 2, the tightening portion 20 is spirally configured to cover the triceps surae muscle and ankle in sequence, continuously from the tibial tuberosity of the wearer 100. The lower end of the tightening portion 20 extends to the side of the wearer 100's Achilles tendon. The tightening portion 20 includes a triceps surae portion 24 that covers the triceps surae muscle of the wearer 100 and an ankle portion 25 that covers the wearer 100's ankle. The triceps surae portion 24 is positioned between the anchor portion 21 and the ankle portion 25.

[0035] Next, with reference to Figures 12 to 14, a modified example of the rotational movement tights 1 according to Embodiment 2 will be described.

[0036] In a modified example of the rotational movement tights 2 according to Embodiment 2, the main body portion 10 and the tightening portion 20 extend from the wearer's ankle to the back of the heel. The lower end of the tightening portion 20 extends to straddle the toe portion of the wearer's heel in the left-right direction. The tightening portion 20 includes a heel portion 26 that covers the back of the wearer's heel. The heel portion 26 is connected to the ankle portion 25.

[0037] According to the rotational movement tights 2 of Embodiment 2, the tightening portion 20 is spirally configured to cover the triceps surae muscle and ankle in sequence, starting from the tibial tuberosity of the wearer 100. Therefore, the elastic force of the tightening portion 20, which is spirally configured to cover the triceps surae muscle and ankle in sequence, starting from the tibial tuberosity of the wearer 100, can assist the rotational movement of the wearer's lower body 110. Thus, the rotational movement of the wearer's lower body 110 can be further assisted.

[0038] Furthermore, in a modified example of the rotational movement tights 2 according to Embodiment 2, the tightening portion 20 extends to the back of the wearer's heel 100. This makes it possible to suppress the rotational movement tights 1 from slipping up.

[0039] (Embodiment 3) Unless otherwise specified, the rotational movement tights 3 according to Embodiment 3 have the same configuration and effects as the rotational movement tights 1 according to Embodiment 1.

[0040] Referring to Figures 15 and 16, the rotational movement tights 3 according to Embodiment 3 differ from the rotational movement tights 1 according to Embodiment 1 in that the main body portion 10 and the tightening portion 20 extend to the abdomen of the wearer 100.

[0041] In the rotational movement tights 3 according to Embodiment 3, the tightening portion 20 is spirally configured to cover the abdomen, continuous with the gluteus maximus of the wearer 100. The upper end of the tightening portion 20 extends from the waist of the wearer 100, through the center of the abdomen, to the flank. The tightening portion 20 crosses above the navel of the wearer 100 and extends to the lower back. This allows the tightening portion 20 to assist the external oblique muscle. The tightening portion 20 includes an abdominal area 27 that covers the abdomen of the wearer 100. The abdominal area 27 branches off from the gluteus maximus portion 22 in an abdominal direction different from the extension direction of the biceps femoris muscle, and covers the abdomen.

[0042] According to the rotational movement tights 3 of Embodiment 3, the tightening portion 20 is spirally configured to cover the abdomen, continuously extending from the gluteus maximus of the wearer 100. Therefore, the elastic force of the tightening portion 20 can assist the rotational movement of the lower body 110 of the wearer 100. Thus, the rotational movement of the lower body 110 of the wearer 100 can be further assisted.

[0043] The above embodiments can be combined as appropriate. The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description and is intended to include all modifications in the sense and scope equivalent to the claims.
