Description

[Technical Field]

[0001] The present invention relates to pressure-adjustable clothing such as socks, stockings, and supporters worn on the thighs, lower legs, upper arms, etc., with adjustable pressure. [Background technology]

[0002] Conventionally, compression socks with gradually varying pressure levels from strong to medium to weak from the ankle to the calf have been put to practical use as general medical devices for preventing swelling, improving blood flow, and promoting circulation. These compression socks vary the pressure by knitting the ankle with a material that is more contractile than the calf, or by reducing the stitch size and the amount of elastic yarn inserted in the ankle area and increasing the stitch size and the amount of elastic yarn inserted in the calf area. For example, the pressure is set to 21 to 32 hPa at the ankle and 17 to 23 Pa at the maximum calf circumference.

[0003] Because the thickness and shape of the lower leg vary from person to person, conventional compression socks had problems such as having to be individually made to fit each individual's lower leg thickness and shape, requiring a large number of different types to be available, making it difficult to measure the thickness and shape of the lower leg, and making it difficult to select the right size.

[0004] Compression socks have a variety of uses, such as eliminating differences in swelling in the lower legs between morning and evening, suppressing unnecessary movement during exercise, and promoting venous return. They are used at different times, such as during exercise, after exercise, at rest, and while active. Furthermore, for elderly people, people with disabilities, and people with symptoms, they need to be easy to wear and provide sufficient compression. Thus, there is a demand for compression socks that can be used in a variety of situations.

[0005] Rather than buying compression socks with different functional concepts, such as stronger socks in the lower part of the body or around the soleus muscle, there is a demand for compression socks that can be adjusted to suit the function needed at any given time, to fit the thickness and shape of each person's legs, and to suit daily physical conditions, differences in swelling between morning and evening, and the degree of improvement.

[0006] Patent Document 1 describes a supporter and socks equipped with the supporter, in which long elastic fabric sections with one end located on one opening side and the other on the other opening side and intermediate fabric sections are alternately arranged in the circumferential direction, and the tightening force can be adjusted by twisting one opening side relative to the other opening side. When this supporter and sock are attached to the calf or the like by twisting one opening side relative to the other opening side, the supporter shrinks radially, tightening and squeezing the calf or the like, thereby effectively reducing swelling. Furthermore, when wearing the supporter and socks, the amount of radial shrinkage changes depending on the amount of twisting, so it can be worn with an appropriate tightening force to suit the thickness of the calf or the like to be worn.

[0007] However, the supporter in Patent Document 1 has problems with the elastic fabric portion being arranged in a spiral, which causes distortion in the fabric when twisted, resulting in wrinkles and a poor appearance, and the skin being partially compressed along the wrinkles. Furthermore, the lack of handles makes it difficult to twist. Furthermore, the tightness of the supporter changes each time it is worn, making it difficult to adjust according to the situation. Furthermore, there are problems with the supporter being too tight, and it being difficult to notice the effects of improving swelling, etc. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Utility Model Registration No. 3091572 Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention was made in consideration of the problems of the conventional problems described above, and aims to provide a pressure-adjustable garment that is easy to twist, does not wrinkle when twisted, allows the amount of tightness to be easily adjusted according to the situation, and has a confirmed effect of improving swelling, etc. [Means for solving the problem]

[0010] The means for solving the above problem is A pressure-adjustable garment having a tubular portion knitted by inserting an elastic yarn, and capable of adjusting the pressure by twisting the tubular portion in the circumferential direction, The tubular portion is characterized in that portions without stitches of face yarn are provided linearly in the wale direction at regular intervals in the course direction.

[0011] The length of the opening of the tubular part is preferably 1 / 5 to 1 / 2 of the half circumference of the opening.

[0012] The opening portion is made up of an outer portion and an inner portion folded back from the upper end of the outer portion, and it is preferable that the inner portion has higher friction against the skin than the outer portion.

[0013] The opening portion is preferably thicker than the tubular portion other than the opening portion.

[0014] It is preferable that the cylindrical portion is provided with pressure adjustment marks along the circumferential direction.

[0015] It is preferable that the tubular portion has a pressure confirmation line between one end (the opening side) and the other end.

[0016] It is preferable that the cylindrical portion is provided with a direction marking indicating the direction in which the clothing should be twisted.

[0017] It is preferable that the cylindrical portion is provided with a left / right identification mark indicating the left and right sides of the garment.

[0018] It is preferable that the pressure confirmation line is provided linearly in the axial direction of the tubular portion, and that the pressure confirmation line is knitted by skipping the elastic yarn over a plurality of wales along the pressure confirmation line.

[0019] The pressure adjustment marks are preferably knitted by additional yarn knitting in which additional yarns are inserted into a plurality of wales along the scale lines.

[0020] The pressure confirmation line is a spiral line arranged in a spiral shape in the circumferential direction of the tubular portion, and it is preferable that the spiral line is knitted in the course direction with stitches having at least one skip stitch where the surface yarn is skipped, and the skip stitch is knitted so as to be shifted in the wale direction. [Effects of the Invention]

[0021] According to the invention of claim 1, the stitch-free portions of the face yarn are arranged linearly in the wale direction at regular intervals in the course direction, so that when the tubular part is twisted, the shift in stitches is absorbed by the stitch-free portions, making it less likely for wrinkles to occur.

[0022] According to the invention of claim 2, the length of the opening portion is 1 / 5 to 1 / 2 of the semi-circumference of the opening portion, which is relatively long, and has the effect of allowing the opening portion to be used as a handle to easily twist the tubular portion.

[0023] According to the invention of claim 3, the inner part of the opening has higher friction against the skin than the outer part and is less likely to slip against the skin, so the twisted tubular part is less likely to return to its original shape, which has the effect of maintaining the adjusted pressure.

[0024] According to the invention of claim 4, the opening portion is thicker than the tubular portion other than the opening, which has the effect that when twisting the tubular portion, the opening portion can be used as a handle to easily twist the tubular portion.

[0025] According to the invention of claim 5, when the user twists the clothing, the position of the compression adjustment mark changes, and as a result, the user can tell from the compression adjustment mark how twisted the clothing is, so the amount of compression can be easily adjusted by changing the position of the compression adjustment mark depending on the user's situation, such as the purpose, use, and time of use of the compression adjustable clothing. Also, it has the effect of being able to confirm the effect of improving swelling, etc., by whether the amount of compression feels weak when the compression adjustment mark is adjusted to the same as when the clothing was first worn.

[0026] According to the invention of claim 6, when the user twists the garment, the position and shape of the compression confirmation line change, and as a result, the user can tell how twisted the garment is from the position and shape of the compression confirmation line, so the amount of compression can be easily adjusted by checking the curve, i.e., the degree of bending, of the compression confirmation line that passes through each part (such as the opening, calf, ankle, etc.) depending on the user's situation, such as the purpose, use, and time of use of the compression-adjustable garment. Also, it has the effect of being able to check the effect of improving swelling, etc., by checking whether the amount of compression feels weaker when the position and shape of the compression confirmation line is adjusted to the same as when the garment was first worn.

[0027] According to the inventions of claims 7 and 8, the effect is that the correct amount of tightening can be applied to the clothing by twisting the clothing in the direction of the direction mark while putting it on or after putting it on, in line with the left and right identification marks.

DETAILED DESCRIPTION OF THE INVENTION

[0029] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0030] FIG. 1 shows a compression sock 1 according to an embodiment of the present invention (hereinafter simply referred to as "compression sock") in relation to a person's lower leg. The compression sock 1 has an upper calf section 2 covering the upper part of the person's calf A, a maximum calf circumference section 3 covering the maximum circumference section of the calf A, a lower calf section 4 covering the lower part of the calf A, a shin section 5 covering the shin B, a minimum ankle circumference section 6 covering the minimum circumference section of the ankle C, and a foot section 7 covering the foot F. A heel section 8 and a toe section 9 are knitted into the foot section 7. The upper part of the foot section 7 is referred to as a leg section 10, which is a tubular section of the present invention. An opening section 11 is knitted above the upper calf section 2, and an ankle section 12 is knitted below the minimum ankle circumference section 6 and is connected to the foot section 7. A calf section 13 is formed from the upper calf section 2 through the maximum calf circumference section 3 to the lower calf section 4. The compression sock 1 is knitted using a circular knitting machine.

[0031] A pressure confirmation line 14 extending from the opening side to the heel side is provided on the calf side of the compression sock 1. A pressure adjustment mark 15 is provided along the circumferential direction on the calf side of the opening part 11 of the compression sock 1. Furthermore, a direction mark 16 indicating the direction in which the compression sock 1 should be twisted and a left / right identification mark 17 indicating whether the compression sock 1 is for right-handed or left-handed use (Fig. 1 shows an L mark for left-handed use) are provided on the shin side of the opening part 11 of the compression sock 1.

[0032] Figure 2 shows the knitting structure of the compression sock 1. The knitting structure of the compression sock 1 is a so-called insertion knitting, in which an elastic yarn (also called "rubber yarn") 23 is inserted into a plain knit structure in which a front yarn 21 and a back yarn 22 are added and fed. Stretch polyester can be used as the front yarn 21, and a single covered yarn (scy) can be used as the back yarn 22, which is made by wrapping a polyurethane yarn (spandex yarn) once with a polyester yarn to cover it. A double covered yarn (dcy) can be used as the elastic yarn 23, which is made by wrapping a polyurethane yarn twice with a polyester yarn in opposite directions to cover it.

[0033] According to the Human Body Measurement Database (Source: Artificial Intelligence Research Center, https: / / www.airc.aist.go.jp / dhrt / 91-92 / data / list.html), if the maximum circumference of a human leg's calf is 100, the minimum circumference of the ankle is 60.5. The circumference of the upper calf was calculated as 88.4 from the ratio of the circumference of the upper calf to the maximum circumference of a mannequin (manufactured by Nanasai Co., Ltd.). Based on this value, the upper calf 2, maximum calf circumference part 3, and minimum ankle circumference part 6 of compression socks 1 were knitted with different stitch counts and amounts of elastic yarn inserted (hereinafter referred to as "elastic insertion amount") as shown in Table 1.

[0034] [Table 1]

[0035] When knitting the compression socks 1 using a circular knitting machine, the stitch density and elastic feed settings of the circular knitting machine when knitting the maximum calf circumference portion 3 are used as a reference, and the stitch density and elastic feed settings of the circular knitting machine when knitting the upper calf portion 2 and the minimum ankle circumference portion 6 are set to the ratios shown in Table 1.

[0036] Specifically, when the compression sock 1 is knitted from the opening 11 on a circular knitting machine, as shown in Figure 1(b), the stitch count from the upper calf 2 to the maximum calf circumference 3 increases stepwise from 90 to 100 every one or several courses, and the amount of inserted rubber also increases stepwise from 95 to 100 every one or several courses. The stitch count from the maximum calf circumference 3 to the minimum ankle circumference 6 decreases stepwise from 100 to 70 every one or several courses, and the amount of inserted rubber also decreases stepwise from 100 to 50 every one or several courses.

[0037] As shown in Figure 2, the stitch density indicates the size of the stitch loop; the larger the stitch density, the coarser the stitch and the greater the amount of lateral stretch; the smaller the stitch density, the tighter the stitch density and the less lateral stretch. In Figure 2, the stitch density of the calf region 13 is N3 = 100, while the stitch density N2 of the upper calf region 2 and the opening region 11 is 90, the stitch density N5 of the shin region 5 is 85, and the stitch density N6 of the minimum ankle circumference region 6 and the ankle region 12 is 70. The amount of inserted rubber indicates the amount of rubber yarn fed; the larger the amount of inserted rubber, the looser the fit, and the smaller the amount of inserted rubber, the tighter the fit.

[0038] When the stitch count is constant, if the amount of inserted rubber is large, the elastic will not tighten when stretched laterally, and if the amount of inserted rubber is small, the elastic will tighten when stretched laterally. Also, when the amount of inserted rubber is constant, if the stitch count is large, the elastic will stretch laterally, and if the stitch count is small, the elastic will stretch less laterally. Therefore, the tightness when wearing compression socks 1 depends on the rubber contraction rate E H If the ratio is small, the fabric will be tight and the fabric allowance N H Therefore, in Table 1, the rubber shrinkage rate (E H ) is the inverse of the fabric allowance rate (N H ) ratio (1 / (E H / 100)×1 / (N H / 100)×100=H 2 / NE×100) is the compression level. Table 1 shows that at the upper calf 2 (fabric allowance: 102, rubber shrinkage rate: 107), the rubber does not dig into the skin and yet is difficult to slip down, and at the ankle minimum circumference 6 (fabric allowance: 116, rubber shrinkage rate: 82.6), the lateral stretch is large and although it passes easily through the foot maximum circumference E when worn, it is tightly fastened with the rubber thread. In other words, the compression level increases in the order of upper calf 2 (compression level: 91.4), maximum calf circumference 3 (compression level: 100), and minimum ankle circumference 6 (compression level: 104.6), demonstrating that the compression function is being fulfilled.

[0039] In Table 1, the ratio (E / Nx100) of the amount of rubber inserted (E) to the stitch count (N) increases in the order of 6 at the ankle's smallest circumference, 3 at the calf's largest circumference, and 2 at the upper calf, indicating that the tightness decreases.

[0040] Furthermore, in Table 1, the ratio (N / Ex100) of the stitch count (N) to the amount of rubber inserted (E) decreases in the order of the ankle minimum circumference part 6, the calf maximum circumference part 3, and the upper calf part 2, indicating that not only are they less likely to slip down, but the ankle minimum circumference part 6 has greater lateral stretch, making it easier to pass through the foot maximum circumference part E when worn.

[0041] As shown in FIG. 3, the pressure confirmation line 14 is knitted by inserting elastic yarn 23 at the calf side between the opening 11 and the ankle 12 of the pressure sock 1, skipping multiple wales. 2, from right to left, one wale is skipped, and the elastic yarn is inserted and knitted into every wale (1-1 hakama), and as the pressure confirmation line 14 approaches, three wales are skipped across the center line S of the pressure confirmation line 14 and knitted (3-1 hakama), and thereafter, one wale is skipped, and the elastic yarn 23 is inserted and knitted into every wale (1-1 hakama). As a result, the fabric for three wales expands, and is knitted in a state where the front is convex and the back is concave, and when viewed from the front, a bulging pressure confirmation line 14 extends from the opening side to the heel side.

[0042] The pressure confirmation line 14 may be a continuous line from the opening 11 to the ankle 12 as shown in Fig. 3, or a dashed line as shown in Fig. 4(a) and Fig. 4(b). The pressure confirmation line 14 in Fig. 4(b) is knitted by repeating 1-1 hakama, 2-1 hakama, 3-1 hakama, 3-1 hakama, 2-1 hakama, and 1-1 hakama in the course direction as shown in Fig. 5.

[0043] As shown in Figure 3, the pressure adjustment mark 15 is provided along the circumferential direction on the outer surface of the calf side of the opening 11 of the compression sock 1. If the center line S of the pressure confirmation line 14 is located at 180°, the pressure adjustment mark 15 is made up of multiple scale lines 15a provided at regular intervals within a range of 135° and 225° on both sides of the circumferential direction based on the center line S of the pressure confirmation line 14. As shown in Figure 6, the pressure adjustment mark 15 is knitted using additional yarn knitting, in which additional yarn 24 is inserted into multiple wales along the scale lines 15a. It is preferable that the additional yarn 24 be a different color from the front yarn 21 and the back yarn 22.

[0044] As shown in Figures 4(a) and 4(b), the pressure adjustment marks 15 may be provided on the inside of the opening 11. Furthermore, the pressure adjustment marks 15 are not limited to scale lines, but may also be variations in the size of shapes such as circles, or the letters weak, medium, and strong, or, as shown in Figure 4(b), may be gradations created by arranging multiple lines of different lengths in the course direction in the wale direction.

[0045] As shown in Figure 3, a direction mark 16 indicating the twisting direction of the compression sock 1 and left and right identification marks 17 of R and L indicating the left and right sides of the compression sock 1 are provided on the inner surface of the shin side of the opening 11 of the compression sock 1 so that they can be seen when putting on the compression sock 1. Like the pressure adjustment mark 15, the direction mark 16 and the left and right identification marks 17 of R and L are knitted using additional yarn knitting, in which additional yarn of a different color than the face yarn is inserted.

[0046] The length of the opening 11, i.e., the length L in the wale direction in FIG. 4(d), is preferably 1 / 5 to 1 / 2 of the half circumference P of the opening 11 (the width of the compression sock 1 when flattened). If the length L is less than 1 / 5 of the half circumference P, there will be fewer handles to hold when twisting the leg 10, making twisting difficult. On the other hand, if the length L is greater than 1 / 2 of the half circumference P, the pressure-applied portion will be smaller. In this embodiment, the relatively long length of the opening 11 makes it easy to twist the leg 10 using the opening 11 as a handle.

[0047] As shown in Figure 4(c), the opening 11 is composed of an outer portion 11a and an inner portion 11b folded back from the top end of the outer portion 11a, and it is preferable that the inner portion 11b has a higher frictional property against the skin than the outer portion 11a. To increase the frictional property, the yarn material for the inner portion 11b can be not only a synthetic yarn such as nanofiber but also a yarn with a high friction coefficient such as a hygroscopic cotton yarn, or the inner portion 11b can be knitted by tuck knitting or the like to raise a portion of the knitted fabric and create an uneven surface that comes into contact with the skin. The high frictional property of the inner portion 11b makes the inner portion 11b of the opening 11 less likely to slip against the skin, which makes it less likely for the twisted leg portion 10 to return to its original position, and the adjusted compression can be maintained.

[0048] The opening portion 11 is preferably thicker than the leg portion 10 other than the opening portion 11. In order to increase the thickness of the opening 11, a double structure of the outer portion 11a and the inner portion 11b is used, and thicker yarn can be used when knitting the inner portion 11b. The thick opening 11 makes it easier to hold, and when twisting the leg portion 10, the tubular portion can be easily twisted using the opening 11 as a handle.

[0049] As already explained, the compression sock 1 according to this embodiment is knitted to a predetermined compression rate, but the compression can be adjusted by twisting the entire leg section 10 from the opening section 11 to the ankle section 12 in the circumferential direction. The method for adjusting the compression will be explained in detail below.

[0050] First, the foot is inserted through the opening 11 of the compression sock 1 and inserted into the foot 7 through the ankle 12. Then, as shown in FIG. 7, the opening 11 is used as a handle to pull the shin 5, calf 13, and opening 11 straight up. Next, as shown in FIG. 8, the shin 5, calf 13, and opening 11 from the ankle 12 upward are twisted in the direction of the direction mark 16. Alternatively, the compression sock may be pulled up while adjusting the pressure on each part. In FIG. 8, the opening 11 of the left compression sock 1L is twisted clockwise when viewed from above, and the opening 11 of the right compression sock 1R is twisted counterclockwise when viewed from above. Alternatively, the shin 5, calf 13, and opening 11 from the ankle 12 upward may be pulled up while twisting them in a predetermined direction. Here, the standard twist is defined as twisting until the central scale line 15a of the pressure adjustment mark 15 provided on the calf side of the opening 11 comes to the shin side, i.e., 0°.

[0051] By twisting the shin section 5, calf section 13 and opening section 11 in a predetermined direction, as shown in Figure 8, the pressure adjustment mark 15 appears on the front and the pressure confirmation line 14 appears in a spiral shape from the front side of the opening section 11 to the back side of the ankle section 12. The spiral shape of the pressure confirmation line 14 differs depending on whether the leg is turnip-shaped as in Figure 8 or radish-shaped as in Figure 9.

[0052] Twisting the shin region 5, calf region 13, and opening region 11 tilts the knitting stitches as shown in FIG. 10, increasing the number of elastic yarns 23 per unit length X in the course direction, thereby increasing the compression. Increasing the amount of twist relative to the standard twist increases the compression, while decreasing the amount of twist relative to the standard twist decreases the compression. The compression adjustment marks 15 and the compression confirmation line 14 change with the amount of twist, i.e., the compression. Therefore, the user can memorize the position of the scale line 15a of the compression adjustment marks 15 or the shape of the compression confirmation line 14 that matches the shape of their lower leg or the purpose of compression. Each time they wear the compression socks 1, they can easily adjust the position of the scale line 15a or the shape of the compression confirmation line 14. It is also easy to weaken or strengthen the compression.

[0053] In this way, with the compression sock 1 of this embodiment, when the user twists the compression sock 1, the compression confirmation line 14 on the calf side twists and appears on the shin side, and as a result the user can tell how twisted the compression sock 1 is from the shape of the compression adjustment confirmation line 14, so the amount of compression can be easily adjusted by changing the shape of the line depending on the user's circumstances, such as the purpose, use, and time of use of the compression sock 1. Furthermore, the effectiveness of improving swelling, etc. can be confirmed by whether the amount of compression feels weak when the compression sock 1 is adjusted to the same line as when it was first worn.

[0054] Furthermore, when the user twists the compression sock 1, the pressure adjustment mark 15 on the calf side appears on the shin side, and the user can see the degree of twisting of the compression sock 1 from the scale line 15a of the pressure adjustment mark 15, so the amount of compression can be easily adjusted by changing the scale line 15a depending on the user's circumstances, such as the purpose and use of the compression sock 1, the time of day, and their physical condition. Furthermore, the effectiveness of the improvement in swelling, etc. can be confirmed by whether the amount of compression feels weak when the scale line 15a is adjusted to the same as when the compression sock 1 was first worn.

[0055] Furthermore, by twisting the compression socks 1 in the direction of the direction mark 16 while putting them on or after putting them on, in line with the R and L left and right identification marks 17, the correct amount of tightening can be applied to the compression socks 1.

[0056] Figure 11 shows leg section 10 knitted using spiral knitting. In spiral knitting, as shown in Figure 12, there are sections with no stitches of face yarn at regular intervals in the course direction, i.e., stitches with skipped stitches 26 in which face yarn 21 is not knitted and only back yarn 22 is used (hereinafter referred to as "skip stitches"), which are knitted in a straight line diagonally in the course direction, and the skip stitches 26 are knitted shifted in the wale direction, resulting in an overall spiral line 25 as shown in Figure 11. The spiral line 25 acts as a buffer when distortion occurs due to twisting.

[0057] 13, when the user twists the compression sock 1, the spiral line 25 twists and changes its inclination, and the user can tell how twisted the compression sock 1 is from the shape of the spiral line 25, so the amount of compression can be easily adjusted by changing the shape of the line depending on the user's circumstances, such as the purpose, use, and time of use of the compression sock 1. In addition, the effectiveness of improving swelling, etc. can be confirmed by whether the amount of compression feels weaker when the spiral line 25 is adjusted to the same as when the compression sock 1 was first worn.

[0058] In the compression sock 1 of Figure 11, there are multiple skips 26 in the course direction, and as a result, when the compression sock 1 is twisted, the deformation of the stitches is absorbed by the skips 26, making it less likely for wrinkles or slack to form in the leg portion 10. Furthermore, even when the compression sock 1 is twisted, the skips 26, which have no face yarn, stretch more in the wale direction than the other stitches, so the compression sock 1 of the present invention shown in Figure 14(a) is prevented from shrinking from height H1 before the leg portion is twisted to height H2 after twisting, as occurs in the conventional compression sock 100 shown in Figure 14(b).

[0059] The present invention is not limited to the above-described embodiments, and can be modified or altered within the scope of the invention as defined in the claims.

[0060] For example, in the above embodiment, the left compression sock 1L is twisted clockwise and the right compression sock 1R is twisted counterclockwise, but conversely, the left compression sock 1L may be twisted counterclockwise and the right compression sock 1R may be twisted clockwise.

[0061] In the above embodiment, the pressure confirmation line extends from the opening side to the heel side, but it may be a single mark provided between one end and the other end of the leg portion (tubular portion) 10. Furthermore, the direction mark indicating the twisting direction in the above embodiment includes arrows, triangles, and other marks indicating directionality.

[0062] In the above embodiment, the pressure-adjustable garment of the present invention is a sock having a foot portion and a leg portion, but the present invention is not limited to socks and can also be applied to stockings, supports worn on the thighs or lower legs (calves), supports worn on the wrists or upper arms, etc. [Explanation of symbols]
