Garment with crotch part

Abstract

A conditioning bottom has a main body and a strong tightening portion which is in the form of a belt and has a tightening force stronger than a tightening force of the main body. This strong tightening portion has first strong tightening portions and a second strong tightening portion. When the conditioning bottom is worn, the first strong tightening portions extend so as to surround gastrocnemius muscles of a wearer along outer edges of the gastrocnemius muscles, and the second strong tightening portion is coupled to the first strong tightening portions and extends through the inside of the wearer's lower leg and thigh to a position of the wearer's crotch. Also, a first mesh portion having a tightening force weaker than the tightening force of the strong tightening portion is formed in a section surrounded by the first strong tightening portions.

Description

CROSS-REFERENCE TO PRIOR APPLICATIONS[0001]This is the U.S. national phase application under 35 U.S.C. §371 of International Patent Application No. PCT / JP2007 / 052636, filed Feb. 14, 2007, and claims the benefit of Japanese Application No. 2006-072916, filed Mar. 16, 2006, both of which are incorporated by reference herein. The International Application was published in Japanese on Sep. 27, 2007 as International Publication No. WO 2007 / 108256 A1 under PCT Article 21(2).TECHNICAL FIELD[0002]The present invention relates to a garment with a crotch part, and particularly to a sports garment with a crotch part.BACKGROUND ART[0003]A lower leg supporter described in Japanese Patent No. 2603769, for example, is known as a conventional garment with a crotch part. This lower leg supporter is constituted by a strong sheet piece that is made of a stretchable fabric having hard strechability that is excellent in tightening force, and a weak sheet piece that is made of a stretchable fabric having...

AI Technical Summary

Benefits of technology

[0009]When, for example, the muscles are used and thereby heat is generated during exercise, the blood flow of the body surface increases in order to dissipate the heat. Therefore, by forming, as described above, the first air-permeable portion with good air permeability in at least part of a section corresponding to a calf that generates a large amount of heat, the generated heat amount can be dissipated suitably without causing an excessive increase in temperature or humidity. As a result, the blood flow of the body surface can be prevented from increasing or, in other words, a sufficient amount of blood flow can be secured in the veins running through the muscles, so that the muscle pumping effect can be achieved sufficiently.

[0010]If the first air-permeable portion is made with a mesh material, it is possible to effectively exert the abovementioned operation and effect that the generated heat amount can be dissipated suitably, a sufficient amount of blood flow can be secured in the veins running through the muscles, and the muscle pumping effect can be sufficiently achieved.

[0011]Moreover, the garment with a crotch part of the present invention may further have a second air-permeable portion having an air permeability higher than the air permeability of the main body. The second air-permeable portion may be formed in at least part of a section corresponding to the front side of the thigh of the wearer. By forming, as described above, the second air-permeable portion with good air permeability in at least part of a section corresponding to the front side of the thigh generating a large amount of heat, it is possible to dissipate the heat amount suitably, secure a sufficient amount of blood flow in the veins running through the muscles, and achieve the muscle pumping effect.

[0012]If the second air-permeable portion is made with a mesh material, it is possible to effectively exert the abovementioned operation and effect that the generated heat amount can be dissipated suitably, a sufficient amount of blood flow can be secured in the veins running through the muscles, and the muscle pumping effect can be sufficiently achieved.

[0013]The present invention can provide a garment with a crotch part which can further enhance venous return.

Problems solved by technology

However, the conventional garment with a crotch part described above cannot exert sufficient acceleration efficiency of venous return.
