Description

Description: TECHNICAL FIELD The present invention relates to a pregnant women's belt, and more particularly, to a pregnant women's belt of a belly-wrapped circular knitted fabric knitted by a circular knitting machine.

(Prior Art) As a belt worn to protect the abdomen of pregnant women since ancient times, bleaching has been used, but it takes a lot of time to wrap around the abdomen and wear it.

Therefore, recently, a pregnant women's belt 1 of a belly-wrapped circular knitted fabric is provided as shown in FIG. This maternity belt 1 is formed by simply adding a highly elastic yarn 3 to a stitch (not shown) of a knitted knitted fabric of ground yarn.
Has a substantially cylindrical configuration in which is spirally penetrated.

(Problems to be Solved by the Invention) The original purpose of the maternity belt is to keep the whole abdomen of the pregnant woman warm and to support the lower abdomen of the pregnant woman from below so that the lower abdomen of the pregnant woman is not lowered by the weight of the fetus, and In order to prevent the pregnant woman from bending down due to the weight of the fetus, the pregnant woman's back is pressed like a splint and straightened. However, in the conventional pregnant women's belt as shown in FIG. 9, the elasticity of the whole knitted fabric is uniform, the force for supporting the lower abdomen of the pregnant woman from below is insufficient, and the pregnant woman's back is sufficiently fitted. Without this, there is a problem that the force to press the back of the pregnant woman and straighten it is insufficient. In order to reinforce the force to support the lower abdomen of a pregnant woman from below, a fastening belt fixed with a fastener such as a hook-and-loop fastener has been conventionally used in combination. When such a belt is used in combination, there is a problem that a strong force is applied to the fixing tool because the lower abdomen is strongly tightened, and the fixing tool is easily damaged. In addition, there is a problem in that a portion where the conventional belt for a pregnant woman and the tightening belt overlap is bulky, and the portion is uneven and looks unnatural when the pregnant woman wears clothes.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned problems of the conventional pregnant women's belt and to provide a pregnant woman's belt of a circular knitted fabric capable of forming the abdomen and the back according to the shape of the abdomen of the pregnant woman. And

(Means for Solving the Problems) The pregnant women's belt according to the present invention has the following configuration to achieve the above object.

That is, the maternity belt according to the present invention is knitted by a circular knitting machine, and is a belly-wound type consisting of four parts of an upper abdomen abutment part, a lower abdomen abutment part, an upper back abutment part, and a lower back abutment part. , The whole is made of knitted fabric of ground yarn, that is, ordinary yarn such as wire, and at the same time, the ferroelastic yarn is spirally threaded through the knit of ground yarn and its diameter is changed Thereby, the outer shape of the entire knitted fabric is formed. Pile yarn is knitted on the inner surface of the knitted fabric. The circumferential elastic force of the strong elastic system at the lower abdomen contact portion and the lower back contact portion is greater than the circumferential elastic force of the strong elastic yarn at the upper abdomen contact portion and the upper back contact portion.

Further, the knitting structure of each part is as follows. That is, in the upper abdomen contact portion and the lower abdomen contact portion,
The ground thread and the weak elastic thread alternately make a knitted course,
In the upper back contact portion and the lower back contact portion, the weak elastic yarn does not independently form a stitch.

In the above configuration, in order to cause a difference in the elastic force in the circumferential direction of the ferroelastic yarn between the lower abdomen contact portion and the lower back contact portion and the upper abdomen contact portion and the upper back contact portion, The number of ferroelastic yarns used for the former may be larger than the number of ferroelastic yarns used for the latter, or thicker ferroelasticity having a larger elastic force than the ferroelastic yarn used for the latter may be used for the former. .

Further, in the upper back contact portion and the lower back contact portion, the weak elastic yarn is unnecessary. Of course, a weak elastic yarn may be woven in this portion, but it is necessary to suppress the extension of the weak elastic yarn. For example, this can be achieved by superimposing a weak elastic yarn on the ground yarn and forming a stitch together with the ground yarn. Further, the weak elastic yarn may be floated from the knitted fabric of the ground yarn without being knitted properly.

 The floating weak elastic yarn may be removed.

In the present invention, at least two types of elastic yarns having different elastic forces are used, and in the case of two types, the one having a large elastic force is called a strong elastic yarn, and the one having a small elastic force is a weak elastic yarn. Called.

(Operation) In the present invention, at least two kinds of elastic yarns are used, and the upper abdomen contact portion, the upper back contact portion, the lower abdomen contact portion,
Obtaining the elasticity and elasticity of the above four parts corresponding to the shape and movement of the upper and lower back, lower abdomen and lower back of the pregnant woman by making the knitting structure of each of the four parts of the lower back contact part different Can be. In addition, since the pile yarn is knitted on the inner surface of the knitted fabric, it goes without saying that the abdomen of the pregnant woman can be well kept warm when worn.

In the upper abdomen contact part and the lower abdomen abutment part, in addition to the ground yarn, the weak elastic yarn also forms the stitch, so compared to the case of only the ground yarn, the stitch is rich in both vertical and horizontal elasticity I have. In addition, since the lower abdomen abutment portion is further provided with a strong elastic yarn, the contraction force with respect to the same magnitude of tension in the lateral direction of the stitch, in other words, the circumferential direction of the strong elastic yarn, is greater than that of the upper abdomen abutment portion. It is big. In addition, the upper back contact portion and the lower back contact portion are basically made of knitted ground yarn, and the weak elastic yarn has no stitch, so it extends in the horizontal direction of the stitch, In the longitudinal direction, it hardly extends compared to the upper abdomen abutment and the lower abdomen abutment, and the lower back abutment has the same size in the circumferential direction of the ferroelastic yarn as the upper back abutment. Large contraction force against tension.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1A and 1B to FIGS. 8A and 8B.

FIG. 1B shows the external shape of the maternity belt 1 according to the present invention. 7 is a contact with the pregnant woman's spine when worn, and curved portions 7, 8 from the upper back contact portion II to the lower back contact portion IV are upper abdomen contact portion I passing over the navel of the pregnant woman and lower abdomen contact. A curved line 8 extending to the part III. As shown in FIG. 1B, the ratio of the upper abdominal contact portion I and the lower abdominal contact portion III to the whole is significantly larger than the ratio of the upper back contact portion II and the lower back contact portion IV to the whole. This is because the upper abdominal contact portion I and the lower abdominal contact portion III are set so as to be in good contact with the abdomen of a pregnant woman that swells as the fetus grows. The lower end line 9 from the lower abdomen abutment part III to the lower back abutment part IV is upwardly sloping in the drawing because the lower end line 9 is worn when worn.
This is for bringing the lower abdomen lower end 10 and the buttocks upper end 11 of the pregnant woman into contact with each other. As described above, the pregnant woman's belt 1 according to the present embodiment, even in a state where it is not worn, presents an outer shape better similar to the shape of a pregnant woman as compared with the conventional pregnant woman's belt 1 as shown in FIG. is there.

FIG. 2 shows how the ferroelastic yarn 3 for creating the outer shape is contained in the pregnant women's belt 1 according to the present invention. The diameter of the ferroelastic yarn 3 is continuously increased and changed from the mouth 1a to the mouth 1b. Also, 1A
The figure shows the external shape of the pregnant woman's belt 1 according to the present invention when worn by a pregnant woman, and is drawn from the same direction as FIG. 1B. As is clear from FIG. 1A, the pregnant women's belt 1 according to the present invention fits very well to the body shape of a pregnant woman.
The upper abdomen abutment part I and the lower abdomen abutment part III extend well in both the vertical and horizontal directions of the stitch corresponding to the degree of swelling of the abdomen of the pregnant woman, and the curved line 8 is larger than that in the case of FIG. 1B. It protrudes to the left of the drawing. The curved line 7 is in good contact with and presses against the spine of the pregnant woman. Furthermore, the lower end line 9 from the lower abdomen contact portion III to the lower back contact portion IV connects the lower abdomen lower end 10 and the buttocks upper end 11, and the inclination of the lower end line 9 raises the lower end portion, in other words, This has the effect of supporting the lower abdomen from below.

Next, upper abdomen contact part I, upper back contact part II, lower abdomen contact part III,
The braided structure in each lower back contact part IV will be described. FIG. 3 shows the knitting structure in the upper abdominal contact portion I. The ground yarn 2 and the weak elastic yarn 4 alternately form a knitted course, and the ground yarn is placed under the knitted course of the weak elastic yarn 4. One ferroelastic thread 3 is passed through between a set of courses in which the courses of the second stitch continue. In this part, the weak elastic yarn 4 together with the ground yarn 2 independently forms a stitch, can be extended well in both the vertical and horizontal directions of the stitch, and has elasticity in both directions.

FIG. 4 shows the knitting structure in the upper back abutting portion II, in which the weak elastic yarn 4 forming the original stitch in the upper abdomen abutting portion I is one side in the lateral direction of the stitch in this portion. Every other is superimposed on the ground yarn 2 to form a stitch. Further, one of the strong elastic yarns 3 is passed through a course of a stitch formed by laminating the ground yarns 2 and the weak elastic yarns 4. Since this portion is hindered by the stretch ground yarn 2 of the weak elastic yarn 4, it can slightly expand in the horizontal direction of the stitch and has elasticity, but hardly expands in the vertical direction.

FIG. 5 shows the knitting structure in the lower abdominal contact part III, in which the ground yarn 2 and the weak elastic yarn 4 alternately form a knitted course, and the ground yarn 2 is placed under the weak elastic yarn 4 knitted course. Two ferroelastic yarns 3 are passed between sets of courses in which the courses of the stitches are connected. The only difference from the upper abdomen abutment part I is that the ferroelastic yarns 3 are threaded in pairs.

FIG. 6 shows the knitting structure in the lower back contact part IV, in which the weak elastic yarn 4 forming the original stitch in the lower abdomen contact part III is one in the lateral direction of the stitch in this part. Every other is superimposed on the ground yarn 2 to make a stitch.
Further, the two strong elastic yarns 3 are passed through a course of a stitch formed by superimposing the ground yarns 2 and the weak elastic yarns 4. The only difference from the upper back contact portion II is that the two ferroelastic yarns 3 are threaded in pairs. In the present embodiment, the number of ferroelastic yarns in the lower abdomen contact portion III and the lower back abutment portion IV is increased with respect to the upper abdomen contact portion I and the upper back contact portion II, whereby the former is improved. This increases the elasticity of the latter ferroelastic yarn in the circumferential direction. As for the pile yarn 6, the pile yarn 6 is entangled with both the ground yarn 2 and the weak elastic yarn 4 in the upper abdomen abutment portion I and the lower abdomen abutment portion III. In the lower back contact part IV, the pile yarn 6 is entangled only with the ground yarn 2.

FIG. 7 shows a schematic structure of a circular knitting machine used to obtain the above-described knitting structure. According to such a circular knitting machine, each yarn is supplied from the yarn supply ports A ₁ , A ₂ , B ₁ , B ₂ , C ₁ , and C ₂ around the same while the center hook 5 rotates. The above knitting structure is obtained.

FIG. 8A illustrates the course of the upper abdomen contact portion I and the upper back contact portion II knitted by the circular knitting machine. In the upper abdomen contact portion I, the yarn supply port of the circular knitting machine
From A ₁ ground yarn 2 is fed, together with make stitches, pile yarn 6 is supplied from the B ₁ is being entangled in the stitches. The next course is fed weak elastic yarn 4 from A _2, with making stitches, pile yarn 6 is supplied from the B ₂ are entangled in the stitches. By the bite 5 of the knitting machine rotates, the two types of courses of stitches are made alternately, at the strong elastic thread 3 supplied from C ₁ is plain therebetween. In the upper back abutment II, with respect to the stitches of the ground yarn 2 supplied from the A _1, the pile yarn 6 is supplied from the B ₁ is being entangled, weak elastic yarn 4 supplied from the A ₂ is The superelastic yarn 3 is passed through the course of the double stitch. In this part,
Pile yarn 6 from B ₂ traverses the upper back abutment II without being organized. The pile yarn 6 in this portion is cut later. As is clear from the above description, the number of courses in the stitches of the upper back contact portion II is halved with respect to the upper abdomen contact portion I.

FIG. 8B shows a lower abdomen contact portion knitted by the circular knitting machine.
It is for explaining the course of the stitches of III and the lower back contact part IV. As apparent from this figure, the difference from FIG. 8A is that the course of the stitch made by the weak elastic yarn 4 and the ground yarn 2
This means that the number of the ferroelastic yarns 3 supplied from C ₂ and passed through during the course of the stitches to be made increases. Therefore, the course of the stitches of the lower back contact portion IV is halved with respect to the lower abdomen contact portion III.

8A and 8B, the total number of courses from the upper abdomen abutment portion I to the lower abdomen abutment portion III is different from that of the upper back abutment portion II to the lower back abutment. The total number of knitted courses for Part IV is halved. For this reason, the length along the vertical direction of the stitch from the upper abdominal contact portion I to the lower abdominal contact portion III is the length along the vertical direction of the stitch from the upper back contact portion II to the lower back contact portion IV. It is longer than. The difference between the two lengths is
This causes outward bending of the circumference from the upper back contact portion II to the lower back contact portion IV.

(Effects) As is clear from the above description, the present invention has the following effects.

That is, in the upper abdominal contact portion and the lower abdominal contact portion, it is possible to obtain elongation corresponding to the degree of swelling of the abdomen of the pregnant woman at the time of wearing, and it is possible to appropriately tighten the abdomen. Further, in the upper back contact portion and the lower back contact portion, it is possible to obtain a force for pressing the back of the pregnant woman and straightening it. Further, in the lower abdomen abutment, a sufficient force can be obtained to support the lower part of the pregnant woman from below so that the weight of the fetus does not lower the lower abdomen. Therefore, there is no need for a tightening belt which had to be used together when wearing the conventional maternity belt as shown in FIG. Further, the pile yarn on the inner surface of the knitted fabric can exert a sufficient heat retaining effect. The pregnant women's belt according to the present invention can be easily knitted by a circular knitting machine as shown in FIG. 7 and is suitable for mass production.
