Description

  The present invention relates to a shorts-like lower body underwear that does not place a burden on the human body.

  The back body, which is one of the components of the conventional lower body underwear, was not shaped to cover up to the second lumbar vertebra of the human body. There was a problem that the flow was likely to stagnate.

  Also, because it was located near the waist of the human body at the center of the front edge of the waist opening, the front body squeezed the ureter and inferior vena cava to squeeze the ureter, causing urinary bladder drainage problems, It became a cause of blood circulation disorder by compression of the vena cava.

Also, since the opening edge of the waist opening crosses the iliac crest of the human body, the outer abdominal oblique muscle is compressed across the muscle fiber direction of the human external oblique muscle. In addition, there is a problem that the external oblique muscles are pressed by the tightening action of the waist opening portion and blood circulation is inhibited.
Also, if the buttocks of the human body hang down, the great saphenous vein is bent to cause torsion, and the cross-sectional area of passage is reduced to cause a blood flow disorder.

  In addition, as shown in FIG. 7, the connecting side 101 of the thick piece 100 connected to the front body by stitching has an arc shape, and the connecting portion is located at a site crossing the pubic connecting portion of the human body. Around this time, the suture line of the chic piece 100 compresses the human clitoral foreskin, clitoral glans, superficial inguinal lymph nodes, superficial veins of the abdomen, etc., resulting in poor lymphatic circulation and poor circulation. there were.

  Furthermore, since the width W of the crotch part of the chic part piece 100 is set to 70 to 100 mm so as to be substantially the same width as the crotch region of the human body, the groin part (thigh root) of the human body is formed by the chic part piece. There was a problem that the circulation of the lymph fluid in the inguinal lymph nodes was inhibited by the compression, and the circulation to the femoral vein was inhibited by pressing the great saphenous vein.

  Therefore, an object of the present invention is to provide a lower body underwear that can remove a blood circulation disorder factor, improve heat retention, and release pressure on a lymph node.

The inventor of the present invention has been completed through intensive studies in order to solve the above problems.
1. In the lower body underwear where the front side part covering the abdomen and the rear side part covering the buttocks are continuous via the chic part, the center of the rear edge of the waist opening is from the upper edge of the second lumbar part of the human body to the third lumbar vertebrae. The center of the front edge of the waist opening is positioned below the range of 100 to 150 mm from the region between the second lumbar vertebra and the third lumbar vertebra. The lower body underwear characterized by having been set as follows is provided.
2. The left and right upper end portions of the waist opening are set so as to contact the upper end portion of the iliac crest of the human body, and the lower edge portion of the side edge of the front side portion is substantially in the same direction as the muscle fibers of the external oblique muscle of the human body. 2. The lower body undergarment according to 1 above, characterized in that it is stretched.

  According to the lower body underwear of the present invention, the center of the rear edge of the waist opening is set so as to be located within the range from the upper edge of the second lumbar vertebra to the upper edge of the third lumbar vertebra. The second lumbar portion of the human body can be covered with the rear side to keep the kidney warm and promote blood circulation. In addition, since the center of the front edge of the waist opening is set between the second lumbar vertebra and the third lumbar vertebra within a range of 100 to 150 mm from the site, compression to the ureter and inferior vena cava The ureter can be squeezed to prevent urine from being discharged into the bladder, and blood flow disturbance due to compression of the inferior vena cava can be improved.

  Further, the left and right upper end portions of the waist opening are set to contact the upper end portion of the iliac crest of the human body, and the lower edge portion of the side edge of the front side portion is substantially the same as the muscle fiber of the external oblique muscle of the human body. By extending in the direction, it is possible to prevent the lateral edge of the front side portion from crossing the muscle fiber direction of the external oblique muscle and pressing the external oblique muscle.

  In addition, if the hem edge of the posterior side is set along the lower side of the buttocks, the buttock of the human body can be supported from below by the side of the posterior side. Can prevent torsion causing blood flow disorder.

  Further, the lower edge portion of the front body constituting the front side portion and the front edge portion of the chic portion piece are joined together, and the lower edge portion of the front body is cut into an inverted V shape, while the front portion of the chic portion piece is If the edge protrudes in an inverted V shape and the top of the front edge of the chic piece is set to be 20 to 50 mm above the pubic joint of the human body, the connection between the front and the chic It can prevent the clitoral foreskin and glans of the human body from being pressed by the part.

  In addition, when the upper edge of the front body is pulled up at the time of wearing, the opening angle of the lower edge of the front body tends to be widened by the force pulling the front body upward, so that the compression force by the joint is reduced It can escape in the direction of the edge of.

  Furthermore, if the width of the crotch part of the chic part is set in the range of 40 to 60 mm, the groin part can be prevented from being pressed by the side edge of the crotch part, and the feeling of tightening of the groin part is released.
