Definitions

  • the present invention relates to garments, in particular, to a garment capable of holding a posture in which the chest is elevated and the back is straightened and capable of improving a body function by simply being worn, and particularly suitably used as an undershirt.
  • a tension section having a shape of a laterally facing letter H including tension parts 100 , 102 separately located in left and right horizontal directions at an upper part and a lower part on a neck side and a tension part 102 for coupling middles of the upper and lower tension parts 100 , 101 is attached to an inner surface of a main body 105 .
  • left and right scapulae of the wearer are surrounded with the tension parts 101 to 102 , so that the left and right scapulae are pulled closer toward the inner side in the right and left directions at a rear surface side and a movable range of the shoulder joint is widened thereby improving a standing posture and supporting the erector muscle of the spine.
  • the movable region of the arm joint is widened by not arranging the tension section at the position covering an armhole so as not to inhibit the movement of deltoid muscles.
  • the undershirt disclosed in Japanese Laid-Open Patent Publication No. 2004-44070 has a function of actively improving the movement of the shoulders and the arms at the time of pitching and at the time of impact.
  • Such undershirt is made from three types of, first to third, stretch materials in which the tightening force is differed in three stages, where the tightening force is first material ⁇ second material ⁇ third material.
  • the garment provided with a high tightening force part is also proposed in Japanese Laid-Open Patent Publication No. 9-25008 (patent document 3), Japanese Laid-Open Patent Publication No. 2004-263362 (patent document 4), and the like, but the configuration is such that the band-shaped high tightening force part is traversed across the rear surface from left to right and extended to the arm.
  • the tension section does not cover from the shoulder to the sleeve so as not to inhibit the movement of the deltoid muscles to widen the movable range of the shoulder joint, but if the arm drops forward at the time of fatigue and the like, the deltoid muscles may adduct and the left and right scapulae may be pulled by the deltoid muscles so as to easily be in a left and right widening direction as the tension section is not provided between the shoulder joints. In such a case, it is difficult to expand the left and right scapulaes to improve a posture unless the force of pulling the left and right scapulae to each other is made stronger by the tension section. If the force of the tension section is made stronger to improve a posture, however, the tightening feeling at the upper region of the back may further increase.
  • the undershirt of patent document 2 has a function of actively assisting the movement of the shoulders and the arms at the time of hitting and at the time of impact, but the tightening feeling on the back side is strong, similar to patent document 1, as the region 11 of large area having strong tightening force is spread over the region excluding the central back muscle portion of the upper region of the back, and hence it cannot be worn daily.
  • the wearer feels as if a strong force is loaded on both left and right sides of the back, and the left and right scapulae tend to easily adduct with the central part of weak tightening force in between.
  • the garment having the functionality to assist exercise or to correct the posture provided in the related art has a portion with increased tightening force to be arranged on a back surface side arranged in large area at the upper side region of the back, or is arranged so as to traverse the back by taping, and hence the tightening feeling and the oppressing feeling on the back side are strong, and an uncomfortable feeling is occurs when worn daily for a long period of time.
  • improvement can be made as a garment to be worn daily in order to improve the body function and not limited to during exercise.
  • the present invention provides a garment that can be worn daily without the tightening feeling and with satisfactory fitting, the garment being capable of improving the body function at the time of daily performance such as a sitting posture, a standing posture, and a walking posture when worn.
  • a garment is provided that is capable of increasing an adduction of the scapulae and maintaining the backward movement of the shoulders by wearing, and inducing the elevation of the rib cage and obtaining a posture in which the back is straightened, and improving the body function by reducing heart rates and breath rate based thereon.
  • a first aspect of the invention provides a garment including,
  • a main part which includes front and back body sections, and sleeves extending from the front and back body sections towards both arm sides over shoulders;
  • the front and back body sections and the upper arm sections of the sleeves include at least two kinds of stretch materials, which differ in stretchability from each other, including a material for the main part and a material for the first tightening parts having a lower stretchability than the main part. Accordingly, the first tightening parts are more strongly contact with the deltoid muscles than other sites.
  • the front and back body sections and the sleeves may be separate bodies or may integrally configure the main part.
  • the garment is formed from the main part other than the left and right shoulders and the areas of the deltoid muscles of the upper arm, and a high tightening part of large area or a high tightening part that traverses the back are not provided at the back.
  • the tightening feeling and the oppressing feeling on the back side are thus removed.
  • the main part is formed from a material having satisfactory stretchability and preferably a thin material, the garment can be fitted to the body of the wearer so that the wearer does not feel an uncomfortable feeling, and hence can be worn daily.
  • Tightening parts with lower stretchability than other sites are arranged at the area corresponding to the deltoid muscles at the back of the wearer so as to strongly be contact with and stimulate the deltoid muscles at the back of the wearer than other sites.
  • the wearer then can constantly be conscious of the deltoid muscles at the back, so that the left and right scapulae can be induced in the adducting direction of approaching each other and the left and right shoulders can be induced to spread towards the back side.
  • the first tightening part may appropriately disperse the tightening force by being formed to a point group.
  • the deltoid muscles at the back are the sites bridging between the shoulder regions and the sleeve regions with the boundary position (shoulder) of the front and back body sections and the sleeves in between on the garment side.
  • a posture tends to be a slouching posture leaning towards the front side at the time of fatigue or stress, and the left and right scapulae tend to bend towards the front side and the rib cage tends to easily narrow.
  • the wearer can be conscious so as not to take the slouching posture of leaning forward by constantly stimulating the deltoid muscles at the back.
  • the first tightening parts of low stretchability are arranged at the site of the deltoid muscles continuing to the left and right scapulae, even when the left and right scapulae attempt to bend toward the front side, the first tightening parts do not follow the movement of the left and right scapulae, and induce the left and right scapulae in the adducting direction of approaching each other, and pull the left and right scapulae toward the back side thereby aiding in the direction of elevating the rib cage.
  • the first tightening parts induce the left and right scapulae toward the back side thereby elevating the rib cage, so that a posture in which the back muscle is straightened can be constantly held.
  • the heart rates can be prevented from increasing and can be further reduced during sitting, standing, and walking.
  • the breath rate can be prevented from increasing and can be further reduced during the daily behavior.
  • the breathing tends to become light or smothering may occur and the heart rate and the breath rate increase in the stress state.
  • the heart rate and the breath rate gradually increase when standing up suddenly or even when walking, whereby breathing becomes heavy and walking may not be continued.
  • an increase in the heart rate and breath rate can be suppressed and further reduced, and the body function can be enhanced by wearing the garment.
  • the tense feeing can be alleviated and a relaxed stable state can be obtained so as to be in a physically and mentally cleared state by wearing the garment.
  • the work can be continued positively and efficiently when worn during work.
  • the first tightening part with lower stretchability than the main part is preferably formed from one of the means selected from (1) to (4).
  • a patch made from the same material as or a different material from the main part is overlapped on an outer surface or an inner surface of the main part, and then sewed, or adhered or thermal compression bonded using a resin adhesive.
  • a patch made from a different material from the main part is filled and arranged in an opening provided in the main part, and joining end edges are sewed.
  • a fabric is changed from the main part with the same material as or a different material from the main part.
  • An elastic resin is applied to the main body.
  • a synthetic fiber such as polyester and polyamide, a cellulose fiber such as rayon and cotton, and a natural fiber such as wool and silk are appropriately used for the main material in the material of the main part with satisfactory stretchability. These materials may be mixed by combined knitting, insertion, pulling and the like for use.
  • the stretch material is preferably mixed to give stretchability to the material of the main part.
  • a polyurethane elastic fiber, a polyester elastomeric fiber, a PTT complex finished yarn (side by side bimetal yarn having poly trimethylene terephthalate as main component) and the like are appropriately used for the stretch material.
  • fabric weight is preferably 100 to 200 g/m 2 . This is because the main part likely becomes sheer and tends to easily rip if smaller than 100 g/m 2 , and becomes thick and heavy and thus causing a massive feeling and hardness and affecting the comfortability if greater than 200 g/m 2 . Fabric weight of the main part is more specifically 120 to 170 g/m 2 .
  • the first tightening part is made to have lower stretchability than the main part using the methods (1) to (4).
  • the tightening force can be enhanced even if the patch is the same material as the main part, and the tightening force become stronger if the patch is overlapped on the main part using the material with lower stretchability than the main part.
  • thermoplastic hot melt resin is suitably used for the resin adhesive, and may be a hot melt resin of polyurethane, polyester, polyolefin, styrene and the like.
  • the method of applying the resin adhesive prevents hardness of the fabric of the main part, where the resin is preferably applied in dot-form rather than being applied over the entire surface to ensure air permeability of the laminated portion with the fabric.
  • the tightening force becomes stronger by using the material of lower stretchability than the main part for the patch.
  • the stretchability of the portion where the fabric is changed is made lower than the main part to provide high tightening force.
  • the tightening part preferably adopts the fabric of reducing the loop length or increasing the number of sinker loops per unit area to suppress deformation of the loop.
  • the knitting yarn may be changed for the main part and the tightening part, where the knitting yarn of low stretchability may be used for the tightening part or a thermal fusion yarn may be used and heated after knitting to be integrally cured.
  • the elastic resin for use includes silicone, urethane, acryl, nylon, and the like.
  • a cross linking agent or a penetrating agent may be contained in the elastic resin as necessary to enhance the permeability and the application intensity to the fabric of the main part.
  • Spraying, transferring, screen printing, and rotary printing may be appropriately used for the application method.
  • Patterns in a mode (area application) of applying all over the range to exert the tightening force, a mode (linear application) of applying in a stripe form, a mode (point group application) of applying in dot form may be appropriately used for the application mode.
  • the point group application is most preferable since the tightening force can be appropriately dispersed.
  • the application mode may have patterns of different types coexisting or patterns of different sizes coexisting.
  • the knitted material having stretchability is suitably used for the fabric of the main part.
  • the knitted material includes lateral knitted material and circular knitted material, and may be either as long as a satisfactory stretchability is obtained.
  • the stretchability of the first tightening part is lower than that of the main part, as described above.
  • the contraction force at the time of 30% extension of the first tightening part is preferably greater than or equal to two times and smaller than or equal to ten times the contraction force at the time of 30% extension of the main part. More preferably, it is greater than or equal to three times and smaller than or equal to eight times.
  • the contraction force is measured with the following method. Assume that a direction of highest stretchability is an A direction and a direction perpendicular to the A direction is a B direction. A rectangular sample having a length of 16 centimeters parallel to the A direction and a width of 2.5 centimeters in the direction (B direction) perpendicular to the A direction is collected for the main part and the first tightening part.
  • both ends on the short side of the rectangle were clamped at a clamping interval of 10 centimeters and a 0 to 80% stretching process was repeated for three times with the tension test equipment, and the recovery force at the time point of 30% extension at the time of third unloading, that is, the contraction force, was measured based on the cut strip method of JIS L 1018.
  • the sample of the tightening part is in a state where the material for forming the main part and the patch are overlapped, and is not a single patch.
  • the contraction force of the first tightening part is preferably greater than or equal to two times and smaller than or equal to ten times the contraction force of the main part in both A direction and B direction measured in the relevant method. This is because the stimulation to apply on the muscle serving as the tightening part may lack if smaller than two times, and the stimulation on the muscle becomes too strong and may give an uncomfortable feeling if greater than ten times.
  • An area of each first tightening part arranged on the left and the right is preferably 10 cm 2 to 300 cm 2 . More preferably, it is 30 cm 2 to 100 cm 2 .

  • the back side of the sleeve is sewed to the back body section as a raglan sleeve, and the first tightening part is preferably arranged at the raglan sleeve.
  • the first tightening part is arranged covering the shoulder and the sleeve at the back, if the sewing line of the back body section and the sleeve is the set-in line along the shoulder hole, the first tightening part is positioned over the sewing line, which is not preferable as sewing becomes difficult and it is not visually satisfactory. Furthermore, in the case of the raglan sleeve with the back body section and the back sleeve sewed at the raglan line, the stretchability is suppressed at the sewing line, and the action of the first tightening part positioned on the raglan sleeve side can be further enhanced.
  • the sleeve may be a short sleeve or a long sleeve, and is a sleeve in which at least the first tightening part can be arranged.
