Explanatory drawing with arrows indicating the direction of movement that receives a large resistance superimposed on FIG. The figure which shows the upper garment of the compression wear which concerns on the modification of embodiment The figure which shows the undergarment of the compression wear which concerns on the modification of embodiment The figure which shows the electromyographic data about an Example and a comparative example in time series Diagram showing cumulative EMG data for Examples and Comparative Examples

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the compression wear 1 according to the embodiment is made of a stretchable fabric so as to be in close contact with the wearer as a whole, and is applied to both the upper garment 2 and the lower garment 3. it can.

The upper garment 2 has a T-shirt shape, covers the wearer's chest, abdomen, shoulders, upper arms and elbows, and is provided with openings at positions through which the wearer's neck, waist and forearms pass. The lower garment 3 has a tights shape, covers the wearer's waist, thighs, and knees, and is provided with openings at positions where the upper end side of the wearer's waist and the lower legs pass. The figure shows sleeves and inseam with a length of 7 parts.

The compression wear 1 has a main body portion 4, a friction portion 5 having a friction coefficient and a tightening force larger than that of the main body portion 4, and a first tightening portion 6 and a second tightening portion 7 having a tightening force larger than that of the main body portion 4. .. The main body portion 4, the friction portion 5, the first tightening portion 6 and the second tightening portion 7 are arranged substantially symmetrically. Further, the lower garment 3 has a belt portion 8 extending along the opening of the lumbar region and containing rubber.

The main body 4 occupies a portion of the compression wear 1 other than the friction portion 5, the first tightening portion 6, the second tightening portion 7, and the belt portion 8. As the fabric of the main body 4, for example, polyester mixed with polyurethane can be used.

On each of the left and right sides, the friction portion 5 of the upper garment 2 extends from the upper surface of the shoulder to the outside of the upper arm to the elbow, and the friction portion 5 of the lower garment 3 extends up and down so as to cover the knee. Exists. In the direction in which the static friction coefficient and the dynamic friction coefficient are the largest, the static friction coefficient and the dynamic friction coefficient of the friction portion 5 are preferably 1.2 to 3 times the static friction coefficient and the dynamic friction coefficient of the main body portion 4, respectively. It is more preferably double to double. Further, in the direction of the lowest elongation rate, that is, the direction of the strongest tightening force, the elongation rate of the friction portion 5 is preferably 0.1 to 0.8 times the elongation rate of the main body portion 4, and is 0. .4 times to 0.8 times is more preferable. The elongation rate is calculated by (length after tension-length before tension) / length before tension x 100 (%) when a test piece having a predetermined width and length is pulled with a predetermined force. Value. For example, Nanofront (registered trademark) commercially available from Teijin Limited can be used as the material for the friction portion 5. The direction in which the static friction coefficient and the dynamic friction coefficient are the highest and the direction in which the elongation rate is the lowest are the most effective directions for hindering the movement of the portion, and in the present embodiment, in the extending direction (longitudinal direction) of the friction portion 5. It is almost the same.

The first tightening portion 6 of the upper garment 2 is connected to the friction portion 5 arranged on the shoulder on each of the left and right sides of the rear surface, passes over the scapula, is curved so as to reach the waist side, and extends in a band shape. ing. The first tightening portion 6 of the lower garment 3 is connected to a strip-shaped portion extending along the upper side of the lumbar region except for the center of the front surface and a strip-shaped portion of the lumbar region on each of the left and right sides of the rear surface so as to straddle the hip joint (buttocks). It has a strip-like extending portion up and down (so as to straddle between the hip and the thigh). The extending direction of the first tightening portion 6 generally coincides with the direction in which the elongation rate is the lowest, and in this direction, the elongation rate of the first tightening portion 6 is 0.05 times the elongation rate of the main body portion 4. It is preferably about 0.4 times, and more preferably 0.2 times to 0.4 times. For example, as the fabric of the first tightening portion 6, a fabric obtained by superimposing another fabric on the fabric of the main body portion 4 can be used. In the first tightening portion 6 arranged on the scapula, the lumbar region, and the hip joint strip, the vertical direction is the direction in which the static friction coefficient and the dynamic friction coefficient are the highest and the elongation rate is the lowest. The first tightening portion 6 may be replaced with the friction portion 5.

The second tightening portion 7 of the upper garment 2 extends diagonally from the inside to the outside along the pectoralis major muscle on each of the left and right sides of the front surface, and extends between the left and right shoulder blades on the rear surface. It extends laterally. The second tightening portion of the lower garment 3 extends vertically and vertically on each of the left and right sides of the front surface so as to straddle the hip joint (so as to straddle between the buttocks and the thighs). The extending direction of the second tightening portion 7 generally coincides with the direction in which the elongation rate is the lowest, and in this direction, the elongation rate of the second tightening portion 7 is 0.05 times the elongation rate of the main body portion 4. It is preferably about 0.4 times, and more preferably 0.05 times to 0.2 times. For example, as the fabric of the second tightening portion 7, a fabric in which a transfer sheet is attached to the fabric of the main body portion 4 can be used. Since the tightening force is very large in the direction in which the transfer sheet extends, a plurality of linear transfer sheets are extended and pasted in the direction in which the tightening force is desired (lateral direction between the shoulder blades and vertical direction on the hip joint). It is preferable to attach it. By arranging in this way, the tightening force in the direction orthogonal to this is weakened, and deterioration of comfort can be suppressed. Further, the second tightening portion 7 may be replaced with the friction portion 5 or the first tightening portion 6.

When you move a joint or scapula, the skin on and around it stretches. Although there are individual differences, the lateral skin extension rate (length after extension / length before extension x 100) when the shoulder joint and scapula are moved is about 110% near the center of the back, and the scapula. It is about 140% in the vicinity, about 120% in the posterior and anterior shoulders, and about 150% in the vicinity of the pectoralis major muscle. The skin extension rate in the vertical direction of the elbow is about 140% in the vicinity of the elbow and about 115% in the portion separated from the elbow by about 1/3 of the length of the forearm and the upper arm. In the compression wear 1 of the present embodiment, the friction portion 5 covers the skins of the shoulders, elbows, and knees having such a high skin extension rate. Since the friction portion 5 has a high coefficient of friction and a large tightening force, it comes into close contact with the wearer's skin and generates a large frictional force with the wearer's skin. The frictional force makes it difficult for the skin to stretch and hinders the movement of that part. Therefore, the portion covered by the friction portion 5 cannot be moved unless a force larger than usual is applied to the muscle. In this way, since the muscles are moved with a force larger than usual, the training effect is enhanced and the rehabilitation effect can be expected.

Further, since the tightening force of the friction portion 5, the first tightening portion 6 and the second tightening portion 7 is applied in a direction that hinders the movement of the wearer, a training effect and a rehabilitation effect can be expected. For example, when the shoulder is pushed forward as shown by the arrow in FIG. 2 (A), the left and right scapulas are displaced so as to be separated from each other as shown by the arrow in FIG. 2 (B). At this time, the second tightening portion 7 extending between the left and right shoulder blades works to prevent this movement. Further, when the hip joint is flexed so as to bend the thigh backward, the tightening force of the second tightening portion 7 arranged in front of the hip joint as shown by the arrow at the upper part of FIG. 2C hinders the movement. Work like. Similarly, when the hip joint is flexed so as to raise the thigh forward, the tightening force of the first tightening portion 6 arranged behind the hip joint as shown by the arrow in FIG. 2 (E) hinders the movement. Work on. Further, when the knee is flexed, the tightening force of the friction portion 5 arranged in front of the knee joint acts to hinder the movement as shown by the arrow at the lower part of FIG. 2C. In this way, in order to move each part, it is necessary to move the muscle with a larger force than usual, so that a training effect and a rehabilitation effect can be expected.

In addition, on the left and right sides of the rear surface, the first tightening portion 6 extending in the vertical direction so as to pass through the scapula acts to hinder the movement of the scapula and the flexion of the torso, and the force when moving the muscles of that portion. Is getting bigger. In addition, the first tightening portion 6 extending along the lumbar region stabilizes the posture of the pelvis and prevents the first tightening portion 6 connected to the pelvis on the posterior surface and straddling the hip joint from slipping down.

The friction portion 5 has a high frictional force with the skin, which causes discomfort to the wearer. In the above embodiment, the friction portion 5 is provided in the portion from the shoulder to the elbow and the knee portion, but the total area occupied by the main body portion 4, the first tightening portion 6 and the second tightening portion 7 is the friction portion 5. Since it is larger than the area it occupies, it reduces discomfort. In addition, compression of the abdomen may cause discomfort to the landing person and inhibit breathing, but since the main body portion arranged in the abdomen has a relatively weak tightening force, the discomfort is reduced and breathing is not inhibited.

3 and 4 show a modified example of the above embodiment. In the modified example of the upper garment 2 shown in FIG. 3, the friction portions 5 are provided in the portions from the left and right shoulders to the elbows, respectively, as in the above embodiment, but the first tightening is performed on the rear surface of the upper garment 2. It differs from the above embodiment in that a friction portion 5 is provided in place of the portion 6 and the second tightening portion 7. Each of the modified examples of the lower garment 3 shown in FIG. 4 is different from the above embodiment in that the friction portion 5 is arranged so as to restrict the movement of not only the knee but also the hip joint.

In the modified example shown in FIG. 3A, on the rear surface of the upper garment 2, the friction portion 5 is connected to the friction portions 5 provided on the left and right shoulders and extends laterally so as to pass over the scapula. Since the friction portion 5 is provided on the rear surface of the upper garment 2 in this way, the force required to move the shoulder and the scapula increases due to the frictional force and the tightening force, the training effect is enhanced, and the rehabilitation effect is expected. it can.

In the modified example shown in FIG. 3B, on the rear surface of the upper garment 2, the friction portions 5 are provided in a cross shape, are connected to the friction portions 5 provided on the left and right shoulders, and laterally pass over the scapula. It extends in the direction and vertically along the spine. In the modified example shown in FIG. 3C, the friction portion 5 is provided in a Y shape on the rear surface of the upper garment 2, and the upper end of the portion extending along the spine is divided into two and is on the scapula. It is connected to the friction portions 5 provided on the left and right shoulders through the passage. In the modified example shown in FIG. 3 (D), on the rear surface of the upper garment 2, the friction portions 5 are connected to the friction portions 5 provided on the left and right shoulders and are directed downward so as to pass over the scapula. And a portion extending laterally so as to be connected to the two left and right portions at the same height as the position of the scapula. In the modified examples shown in FIGS. 3 (B) to 3 (D), the force required to move the shoulder and the scapula and the force required to move the torso to bend are obtained by the frictional force and the tightening force. It will increase, the training effect will increase, and the rehabilitation effect can be expected.

In the modified example shown in FIG. 4A, band-shaped friction portions 5 extending from the belt portion 8 to the lower end are provided on the left and right sides of the front surface and the rear surface, respectively. In the modified example shown in FIG. 4B, the friction portion 5 has a spiral portion extending from the vicinity of the center of the lumbar region on the front surface to the front surface of the hip joint and the rear surface of the thigh portion to the inside of the thigh portion. It has a spiral portion extending from the center of the rear surface of the belt portion 8 to the inside of the lower leg through the posterior region of the hip joint and the anterior region of the knee. In the modified examples shown in FIGS. 4A and 4B, the frictional force and the tightening force increase the force required to move the knee and hip joint, enhance the training effect, and expect a rehabilitation effect.

In the modified example shown in FIG. 4 (C), one band is directed downward from the belt portion 8 on the rear surface, and after passing behind the hip joint, is divided into two and diagonally downward to be divided into two. The friction portion 5 is arranged so that the separated bands become one in front of the knee and reach the lower end of the front surface. In the modified example shown in FIG. 4C, the frictional force and the tightening force increase the force for moving the knee and the force for moving the hip joint so as to raise the thigh forward, and the training effect is enhanced. , Rehabilitation effect can be expected.

Using a DS type tester, the friction coefficient of the main body 4 (part a in FIG. 1 (A)) and the friction part 5 (part c in FIG. 1 (C)) was measured. The measurement results are shown in Table 1.

Further, according to JIS-L1096, the main body portion 4 (part a in FIG. 1 (A)), the friction portion 5 (part c in FIG. 1 (C)), and the first tightening portion 6 (part d in FIG. 1 (E)). And the elongation rate (%) of the second tightening portion 7 (b in FIG. 1 (B)) was measured. The measurement results are shown in Table 2.

Changes in the electric potentials of the chest and thigh muscles during exercise with respect to the embodiment corresponding to the compression wear 1 of the above embodiment and the comparative example in which the entire body is made of the fabric of the main body 4 except for the belt portion 8. Was measured. The same subject wore the clothing according to the examples and the comparative examples, performed predetermined exercises, and measured the change in muscle potential at that time.

FIG. 5 is an electromyogram showing the measurement results, where the vertical axis represents the change in potential and the horizontal axis represents time (seconds). FIG. 6 shows the cumulative total of the absolute values of the potential changes from 3 seconds to 12 seconds after the start of the test. As shown in FIGS. 5 and 6, when the compression wear 1 according to the example was worn as compared with the comparative example, the exercise load increased by about 50%.

Although the description of the specific embodiment is completed above, the present invention can be widely modified without being limited to the above embodiment. The lengths of the sleeves and inseam may be varied and may not cover the elbows and knees unless it is necessary to apply friction and / or tightening forces to the elbows and knees. The widths of the friction portion, the first tightening portion and the second tightening portion may be appropriately changed.
