  For example, when performing work or housework, there is a demand for smooth and easy movement when standing up from a leaning state. In the case of a general stand-up method, since the back is rounded and only the waist moves forward, there is a tendency that the load tends to concentrate on one place.

  The present invention has been made to solve such a problem, and it is possible to disperse the load acting on the wearer by encouraging the wearer to move smoothly when getting up from the leaning state. The aim is to provide possible upper body clothing.

In the upper body garment provided with the main body fabric covering the upper body of the wearer, the main body fabric covering the back surface of the wearer is formed with a plurality of tightening portions having a stronger tightening force than the main body fabric. It is arranged along the position corresponding to the wearer's spine standing muscle, and extends from the position corresponding to the seventh thoracic vertebra to the position corresponding to the twelfth thoracic vertebra in the height direction of the wearer, Connected to the pair of first strips and the lower ends of the pair of first strips across the center , extends in the left-right direction of the wearer, and continues to the front side rather than the side lines on the left and right sides. A vertical line passing through the inner end of the first band at a height position corresponding to the seventh thoracic vertebra, at a height position corresponding to the twelfth thoracic vertebra. The pair of first belt-shaped portions are arranged so as to pass inside from the outer edge of the belt-shaped portion. , Ends of the second strip portion is, in a front side of the wearer, to provide the upper body garment spaced in the lateral direction.

  In the upper body garment having this configuration, a pair of first belt-like portions are arranged across the back center of the spine as a plurality of tightening portions having a tightening force stronger than that of the main body fabric. The pair of belt-like portions are arranged on the back side so as to follow the wearer's spine upright muscle, and extend from a position corresponding to the seventh thoracic vertebra to a position corresponding to the twelfth thoracic vertebra. Accordingly, when the wearer leans forward, the pair of first elongated strips once contracted in the longitudinal direction and the main body fabric contracts, and in conjunction with this, the back is raised with respect to the wearer. Thus, it becomes possible to apply a backward force. At this time, since the pair of belt-like portions are arranged along the position corresponding to the spinal column standing muscle, it is possible to apply a force to raise the back while supporting the function of the muscles of the wearer's back. . Therefore, by promoting the smooth movement of the wearer, the load acting on the wearer is dispersed, and the load is prevented from being concentrated in one place.

  Here, in the present invention, in the left-right direction of the wearer at the height position corresponding to the twelfth thoracic vertebra, the interval between the left end portion of the main body fabric and the left first belt-like portion is P1, and the left and right first When the interval between the belt-like portions is P2, and the gap between the first belt-like portion on the right side and the right end of the main body fabric is P3, P1: P2: P3 = 1 to 2: 1: 1 to 2 ... the structure which satisfies (1) may be sufficient.

  According to this configuration, since the pair of first belt-like portions are arranged at an interval satisfying the above formula (1), the upper body garment applies the force acting on the first belt-like portion to the spine upright muscle. Can work in the direction along.

Frettage clamping unit is connected to the lower end portion of the first strip portions of the pair, extend in the horizontal direction of the wearer, a second strip portion which continues to the front side from the side line of the left and right sides, The end portions of the second belt-like portion are separated in the left-right direction on the front side of the wearer .

  As a result, when the wearer leans forward, the first belt-like portion contracts and the second belt-like portion is pulled, and the main body fabric shrinks. An upward force such as lifting from the side can be applied. Moreover, since the edge part of a 2nd strip | belt-shaped part is spaced apart on the wearer's front side, and the 2nd strip | belt-shaped part is the structure which is not connected on the front side, it inhibits the movement of the chest when a wearer stands up You can avoid it. By these, a wearer's movement can be made smoother, and when getting up from a forward bending, a back and a waist can be moved by a natural flow. Moreover, it is prevented that the 2nd strip | belt-shaped part is the structure which is not connected with the front side, and a wearer's stomach is pressed, and the fall of a feeling of wear can be avoided.

  Moreover, it is good also as a structure which the 2nd strip | belt-shaped part is arrange | positioned so that the front side may incline upwards in the position corresponding to a wearer's side part from the left and right side lines to the front side. As a result, when the first belt-like portion contracts and the second belt-like portion is pulled, an upward force that lifts the entire back from the side acts to be held from the front side rather than the side line. be able to. Since the second belt-like portion is arranged to be inclined upward, the upward force generated by the second belt-like portion can be efficiently applied.

  Further, in the height direction, it may be configured to further include a lower tightening portion that is disposed below and spaced apart from the second belt-shaped portion and covers a position corresponding to the wearer's sacroiliac joint. Good. Thus, when the lower tightening portion is formed so as to cover the position corresponding to the sacroiliac joint from the back side without being connected to the second belt-shaped portion, the lower tightening portion , "The part corresponding to the boundary between the thoracic vertebra and the lumbar spine" that becomes the fulcrum of the back movement can be pushed out from the back to the front. Further, when getting up from a leaning state, it is possible to push a “portion corresponding to the boundary between the spinal column and the pelvis” from the back to the front where the load tends to concentrate. By these, the force which acts on a wearer by a 1st strip | belt-shaped part and a 2nd strip | belt-shaped part can be strengthened effectively. As a result, you can move your back and hips in order with a natural flow when you get up from a forward slouch.

  According to the upper body garment of the present invention, the wearer can be moved easily because it is possible to promote a smooth movement of the wearer and to disperse the load acting on the wearer when standing up from the leaning state. It becomes easy to realize.

  As shown in FIG. 1, the pair of first band-like portions 7 may be connected such that lower end portions thereof are curved toward the rear center side. The lower end portions 7c of the pair of first belt-like portions 7 are connected to form, for example, a U shape.

  The 2nd strip | belt-shaped part 8 is connected with the lower end part 7c of a pair of 1st strip | belt-shaped part 7, and is extended in a wearer's left-right direction. The 2nd strip | belt-shaped part 8 is extended to the front side beyond the side line 5, as shown in FIG.2 and FIG.3. The end portions 8a in the longitudinal direction of the second band-shaped portion 8 are spaced apart in the left-right direction on the front side of the wearer. The end 8a of the second band-shaped portion 8 is separated in the left-right direction in the front body 3 and is not connected.

  The upper side 81 of the second strip 8 may be arranged so as to be inclined obliquely downward from a position intersecting the first strip 7.

The second band-shaped portion 8 is continuous from the left and right side lines 5 to the front side, and is disposed such that the front side is inclined upward at a position corresponding to the side portion of the wearer. The 2nd strip | belt-shaped part 8 is arrange | positioned along the position corresponding to a 12th rib (109N12), for example.

The width W ₈ (interval between the upper side and the lower side) of the second band-shaped portion 8 is preferably 5 cm or more in the vicinity of the side line 5. If the width W8 of the second strip ₈ is too thin, the force acting when the wearer gets up is weakened.

  In the upper body garment 1, a lower tightening portion 9 having a tightening force stronger than that of the main body fabric is formed on the lower main body fabric of the back body 4. The lower tightening portion 9 is disposed below and spaced from the second belt-like portion 8. The lower elastic band member 9 is disposed so as to cover a position corresponding to the wearer's sacroiliac joint 106 (see FIG. 6).

  The lower tightening portion 9 is formed to form a triangle when viewed from the back side. The apex 91 of the lower elastic band member 9 is disposed at a position corresponding to, for example, the fifth lumbar vertebra. The hypotenuse 92 (upper edge) of the lower tightening portion 9 is disposed so as to be inclined downward from the apex 91 and is formed so as to reach the side line 5 at the lower end 2c of the underwear body 2. The hypotenuse 92 of the lower tightening portion 9 may be disposed up to the front side beyond the side line 5 or may be disposed within the back body 4.

  FIG. 6 is a view showing the position of the sacroiliac joint 106. The sacroiliac joint 106 is a part connecting the sacrum 107 and the iliac bone 108. The lower elastic band member 9 is disposed at a position corresponding to the sacroiliac joint 106 as described above. The lower elastic band member 9 is formed so as to cover the position corresponding to the sacroiliac joint 106 from the back side.

  It is preferable that the stretch recovery ratio of the first belt-like portion 7, the second belt-like portion 8, the lower tightening portion 9, and the main body fabric is, for example, about 1.2 to 3.0: 1. If the power (restoring force) of the first belt-like portion 7, the second belt-like portion 8, and the lower tightening portion 9 is excessively weakened, the force F1 (see FIG. 7) for raising the back is weakened. If the power of the first belt-like portion 7, the second belt-like portion 8, and the lower tightening portion 9 is increased too much, the operation of bending forward may be limited.

  The 1st strip | belt-shaped part 7, the 2nd strip | belt-shaped part 8, and the lower side tightening part 9 can be formed by changing the elongation of a knitted fabric, for example. Thereby, the tightening portions (the first belt-like portion 7, the second belt-like portion 8, and the lower tightening portion 9) having a stronger tightening force than the main body fabric can be formed.

  Next, an effect | action at the time of wearing the upper body clothing 1 is demonstrated. FIG. 7 is a side view showing the direction of the force acting on the wearer 100 of the upper body garment 1, and shows a state where the wearer 100 is bent forward. When the upper body garment 1 of this embodiment is worn, when the upper body of the wearer 100 is bent forward, the body fabric of the underwear body 2 is used to shrink the back of the wearer 100. The force acts so as to lift the entire 100a from the side and push the waist 100b of the wearer 100 forward appropriately.

  Specifically, (1) the force F <b> 1 acts to raise the back 100 a of the wearer 100 by using a force that contracts after the pair of first belt-like portions 7 are once stretched. Next, (2) the second band 8 is pulled by the first band 7 in conjunction with the contraction force of the first band 7, and the upward force F2 is lifted from the side with respect to the wearer 100. Works. (3) In conjunction with these forces F1 and F2, the force F3 acts to push the waist 100b of the wearer 100 from behind by the cooperation of the second belt-like portion 8 and the lower tightening portion 9.

  Further, as shown in FIG. 3, the upper body garment 1 is configured so that the movement of the chest of the wearer is not hindered because the end 8a of the second band-shaped portion 8 is not separated and connected on the front side. Yes.

  Next, with reference to FIG. 8, the difference between the case where the conventional upper body garment 1U is worn and the case where the upper body garment 1 of the present embodiment is worn when standing up from the leaning state will be described.

  8 (c) and 8 (d) are views showing the movement when the wearer of the conventional upper body garment 1U stands up from the leaning state from the side. The conventional upper body garment 1U has the same configuration as the upper body garment 1 except that the first belt-like portion 7, the second belt-like portion 8, and the lower tightening portion 9 are not formed.

  When the conventional upper body garment 1U is worn, the back 100a of the wearer 100 is curled when standing up from the leaning state, and only the waist 100b tends to move forward. For this reason, the burden on the wearer 100 is concentrated in one place, the movement is awkward, unnatural and unpleasant.

  FIGS. 8A and 8B are views showing the movement when the wearer 100 of the upper body garment 1 of the present embodiment stands up from the forward bending state from the side. When the upper body garment 1 is worn, the back 100a extends and the back 100a moves upward (arrow a), and then the waist 100b is pushed forward (arrow b). When the upper body garment 1 is worn, since the burden on the wearer 100 is dispersed when standing up from a leaning state, it can move easily. When the upper-body garment 1 is worn, the back 100a and the waist 100b can be moved in a natural flow in order when getting up from a leaning state, instead of maintaining a stretched posture. Thereby, in the upper body garment 1, a beautiful and easy way to stand up can be easily performed.

  Next, with reference to FIG. 9, the muscle activity evaluation of the spinal column standing muscle when the wearer of the upper body garment 1 stands up from the leaning state will be described. FIG. 9 is a graph showing a result of evaluating the muscle activity of the wearer's spine upright muscle. The inventor of the present application conducted an experiment in order to examine the effect on the muscle activity of the spine standing muscle 102 when the upper body garment 1 was worn and the user leaned up from the forward bending state.

6 subjects were put on the upper body garment 1 shown in FIG. 1, and an electromyograph was used to measure the integrated value E of the myoelectric potential of the erected spine 102 when standing up from the leaning state. In addition, as subjects for comparison, 6 subjects wear the upper body garment 1U in which the first tightening portion 7, the second band-shaped portion 8, and the lower tightening portion 9 are not formed. an integrated value E _S of the muscle potential of the erector spinae muscles when standing up was measured.

In FIG. 9, the ratio R (= E / E _S ) with respect to the integrated value E _S of the myoelectric potential in the case of the upper body clothing 1U of the myoelectric integrated value E in the case of the upper body garment 1 is shown for each subject. When the ratio R shown in FIG. 9 is less than 1, it indicates that the integrated value of the myoelectric potential of the spine standing muscle is lower when the upper garment 1 is worn than when the upper garment 1U is worn. . That is, the activity of the spine standing muscle is low and the load on the spine standing muscle is reduced. As shown in FIG. 9, it was found that the load on the spine erecting muscle 102 was reduced for the five subjects (S1 to S4, S6). No effect was observed for one subject (S5). For example, in the subject (S4), the load reduction of about 14% was recognized when the upper body garment 1 was worn.

  Thus, according to the upper body garment 1 according to the present embodiment, the pair of first belt-like portions 7 are arranged along the spine erecting muscle 102 from a position corresponding to the seventh thoracic vertebra to a position corresponding to the second lumbar vertebra. Therefore, the force F1 can be applied so that the force F1 can be applied using the force that the first belt-shaped portion 7 contracts to easily raise the back. Accordingly, the upper body garment 1 can promote a smooth movement of the wearer when getting up from the leaning state, and can disperse the load acting on the wearer.

  In the upper body garment 1, the second belt-like portion 8 connected to the lower ends of the pair of first belt-like portions 7 extends in the left-right direction and is disposed to the front side beyond the side portion, so that the entire back of the wearer An upward force F2 can be applied so as to lift the arm from the side. Thereby, a wearer's movement can be made smoother, and when getting up from a forward bending, a back and a waist can be moved by a natural flow. Moreover, since the 2nd strip | belt-shaped part 8 is the structure which is not connected by the front side, it can prevent that a wearer's stomach is pressed and can avoid a fall of a feeling of wear, and a motion of a wearer's chest is also possible. Uninhibited and can move in a natural flow when getting up from a slouch.

  The present invention is not limited to the above embodiment. In the embodiment described above, the upper body garment 1 is described as warp knitted underwear, but the upper body garment 1 may be other upper body garments. Hereinafter, with reference to FIGS. 10 to 13, other upper body garments 1 </ b> B, 1 </ b> C, 1 </ b> D, and 1 </ b> E that are embodiments of the present invention will be described.
