Description

  The present invention relates to a swimsuit having a water intrusion suppression unit that suppresses water intrusion from the chest. The present invention further relates to a swimsuit having a water intrusion suppression unit that prevents water from entering from the chest.

  In the field of swimsuits, particularly swimsuits for swimmers, swimsuits of the type that covers most of the body using fabrics that are light, have low water absorption, and have low resistance to water, such as plain weave fabrics, are beginning to be developed. The swimsuit is difficult to stretch and has functions such as maintaining the swimmer's body shape.

  For example, in Patent Document 1, a base layer made of stretchable stretchable fabric having a torso portion that covers at least a part of a human torso when worn, and a plurality of panels bonded to the outer surface of the base layer A garment having, for example, a swimsuit is disclosed.

  The above swimsuit is a type of swimsuit that covers from the upper part of the pectoralis major muscle to the ankle, but in particular, when swimming, such as breaststroke, when the arm is pulled and the armpit is moved, water may enter from the chest. This was especially seen in athletes who developed large pectoral muscles. Since the infiltration of water from the chest leads to an increase in water resistance and a slower swimming speed, it is preferable to improve in the world of competitive swimming that competes for 1 / 100th of a second.

  As a technique for the problem of water intrusion into a swimsuit, Patent Document 2 states that a shape along the surface of the human body is formed on at least a part of the back side of the fabric that creates a gap with the human body surface when wearing a breast intermammary site, a back lumbar spine site, Discloses a swimsuit characterized by depositing an elastic polymer. However, since the swimsuit described in Patent Document 2 prevents the chest gap due to the build-up part, even if the chest gap can be prevented at rest, the swimmer's intense body movement and muscle expansion Cannot be followed and water intrusion cannot be effectively suppressed.

  In addition, Patent Document 3 is configured to cover at least partly a material main body formed of a stretchable fabric; and an area between the body main body fixed to the material main body and a high point on the body structure of the user's body. A swimsuit is disclosed that includes a piece of elastic material having a size and shape. However, the swimsuit disclosed in Patent Document 3 increases the tension in the vicinity of the abdomen of the swimsuit and presses the overhanging part of the body, and is not intended to suppress the entry of water from the chest.

  Furthermore, in Patent Document 4, in a women's swimsuit sewn with various stretchable fiber fabric materials or sheet fabric materials, a portion facing the water flow during swimming is provided in a direction parallel to the water flow during swimming. Tightening rectification structure composed of fine ridges formed integrally on the surface of the fabric so as to be in close contact with the fabric fibers by a stretchable resin material such as vinyl chloride, synthetic rubber, polyurethane and silicone, and when swimming A female swimsuit is disclosed in which a water drainage structure sewn with an elastic net cloth is located in the vicinity of an opening where water enters.

  However, the “tightening rectification structure” in the women's swimming swimsuit described in Patent Document 4 is intended for rectification of the chest, and the “drainage structure” is for discharging water that has entered the swimsuit. It is intended to allow the entry of water from the chest in a sense, and is not intended to suppress the entry of water from the chest.
