AI Technical Summary
Maternity bottoms with elastic knitted portions around the waist can cause excessive tightness in pregnant women, reducing comfort and usability.
The design incorporates an expandable member made of a material with higher tension than the main body, positioned on the upper end and back side of the user, which helps distribute tension away from the abdomen and prevent slipping.
This configuration reduces the feeling of tightness in the abdomen while maintaining the necessary tension to prevent the garment from slipping off, thereby enhancing comfort and fit for pregnant women.

Abstract
Description
[Technical field]
[0001] The present invention relates to maternity bottoms which reduce the tightness felt around the abdomen when worn. [Background technology]
[0002] As shown in Patent Document 1 below, bottoms such as leggings have an elastic knitted section that goes around the waist of the wearer, and the tension of this elastic knitted section prevents the bottoms from slipping down from the waist (see Figure 1 of Patent Document 1, etc.). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2019-189963 A Summary of the Invention [Problem to be solved by the invention]
[0004] The bottoms shown in Patent Document 1 have a woven elastic band that goes around the waist, so the tension of the band tightens the entire waist of the wearer uniformly. Therefore, pregnant women with large abdomens feel particularly tight around their abdomens, which causes a problem of significantly reducing comfort when wearing the bottoms.
[0005] Therefore, an object of the present invention is to provide maternity bottoms that reduce the tightness felt around the abdomen when worn. [Means for solving the problem]
[0006] In order to solve the above problems, the present invention provides: A main body portion having elasticity and to be worn on the lower body of a user; An elastic member that is provided at the upper end of the main body and on the back side of the user and is made of a material with a higher tension than the main body; The maternity bottoms having the above features were constructed.
[0007] In this way, the tension of the elastic member does not act directly on the abdomen of the pregnant woman, reducing the feeling of tightness. Moreover, the tension of the elastic member on the back side can prevent the main body from slipping off the waist.
[0008] In the above configuration, it is preferable that the elastic member is made of a mesh material. In this way, the tension of the elastic member can be prevented from becoming excessively large by adjusting the mesh size, etc. In addition, the high breathability of the mesh material can prevent stuffiness around the waist.
[0009] In each of the above configurations, it is preferable that the elastic member is a belt-shaped member having a waist length of 10% to 80% of the waist length of the main body in a free state where no external force is acting. In this way, the tension of the elastic member can prevent the main body from slipping off the waist, and can also prevent the pregnant woman from feeling excessive tightness around her abdomen. Effect of the Invention
[0010] This invention provides an elastic member made of a material with higher tension than the main body portion at the upper end of the main body portion, on the user's back side, thereby preventing the main body portion from slipping off the waist while reducing the feeling of tightness around the abdomen when worn. [Brief description of the drawings]
[0011] [Figure 1] FIG. 1 is a perspective view showing one embodiment of maternity bottoms according to the present invention; [Diagram 2] A cross-sectional view of the main part of the maternity bottoms shown in Figure 1. [Diagram 3] FIG. 2 is a side view showing the state in which the maternity bottoms shown in FIG. 1 are worn. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] An embodiment of maternity bottoms 1 according to the present invention will be described with reference to the drawings. Here, maternity leggings (hereinafter, given the same reference numerals as the maternity bottoms 1) are illustrated as an example of maternity bottoms, but the present invention may be applicable to all maternity bottoms 1 worn on the lower body (for example, tights, stockings, pants, skirts, etc.).
[0013] As shown in Figure 1, the maternity leggings 1 have a main body 2 made of a stretchable material that is formed to cover the entire area from the calves to the lower abdomen of a user E (hereinafter, the same symbol as user E) (see Figure 3), and an elastic member 3 that is provided at the upper end of the main body 2 and on the back side of the pregnant woman E and is made of a material that is more elastic than the main body 2.
[0014] The main body 2 is made of a rayon blend material and has a certain degree of elasticity. At the upper end (around the waist) of the main body 2, a folded-back portion 4 is formed by folding inward and sewing, as shown in the cross section of FIG. 2. The tightening force due to the elasticity of the main body 2 is weak enough that it does not cause an excessive tightness around the abdomen of the pregnant woman E, and can be easily stretched by pulling it toward you with your fingers, as shown in FIG. 3. The material of the main body 2 is merely one example, and can be changed as appropriate as long as it does not cause an excessive tightness around the abdomen of the pregnant woman E and can provide an appropriate fit.
[0015] The elastic member 3 (power net) is a belt-shaped member with a waist length that is approximately 50% of the waist length of the main body portion 2 in a free state where no external force is acting. The belt-shaped width of the elastic member 3 is approximately 2 centimeters. The elastic member 3 is provided on the inside of the folded-back portion 4 (the back side of the main body portion 2). On the front side (abdominal side) of the main body portion 2, there is a portion that consists of only the main body portion 2 and does not have the elastic member 3 provided.
[0016] The waist circumference length of the elastic member 3 can be changed as appropriate, but is preferably within the range of 10% to 80% and more preferably 30% to 60% of the waist circumference length of the main body part 2. If the waist circumference length of the elastic member 3 is shorter than 10%, the effect of preventing the main body part 2 from slipping down is not easily achieved, while if it exceeds 80%, there is a risk of an excessive tightness feeling around the abdomen.
[0017] The elastic member 3 used in this embodiment is a mesh-like material made of 85% polyester and 15% polyurethane, and has a lower tension than general rubber materials. The type and width of the material used for the elastic member 3 are merely examples, and can be changed as appropriate as long as they do not cause excessive tightness around the abdomen of the pregnant woman E. It is also possible to use a non-mesh material for the elastic member 3.
[0018] According to the above-mentioned maternity leggings 1, an elastic member 3 made of a material with higher tension than the main body part 2 is provided at the upper end of the main body part 2, on the back side of the user E, thereby preventing the main body part 2 from slipping down from the waist while reducing the feeling of tightness around the abdomen when worn.
[0019] In the above embodiment, the stretchable member 3 is provided on the main body part 2 (the back side of the maternity leggings 1) that is folded inward, but there are also cases where the stretchable member 3 can be folded into the folded part 4 when the main body part 2 is folded inward. In this way, the stretchable member 3 cannot be seen from the outside, improving the appearance.
[0020] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. Therefore, the scope of the present invention is defined by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
