Abstract

In underwear according to the present invention, a fabric that stretches in both warp and woof is used in front and rear body fabrics (13, 14); the upper side (10) of an area contacting the front and rear body is caused to be recessed in substantially a V-shape, and the front body and rear body are connected to form the underwear; and the underwear is formed so that, when the underwear is laid out flat, both side sections (19, 20) of the underwear and the upper side (10) of the front body form the shape of an inverted W, the feeling of compression in an inner thigh section of the crotch being reduced, and downward slippage of the upper side of a stomach section being prevented.

Description

underwear

The present invention relates to bottom clothing, particularly boxer type and low leg type underwear.

The shape of the base of the human thigh is not circular, and the front of the inner thigh of the thigh is angular, and there is an adductor longus muscle there, so in underwear such as boxer type, the underwear is long. It pressed the adductor longus muscle and caused discomfort such as pain. Therefore, in the angular portion of the inner thigh, the fabric is patched and three-dimensionally sewn.

Three-dimensional sewing is difficult to process and there are many connection points, so productivity is poor. In addition, when wearing three-dimensionally sewn underwear, the sewing thread at the sewn area may give another feeling of oppression to the skin. In recent years, there has been an increasing tendency to reduce irritation to the skin, and underwear that is glued with an adhesive is sold without using elastic cords for the waist and legs, and without sewing threads. Is in demand. In addition to this, a male lower body garment that does not shift up at the hem end and fits each part has been proposed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2009-84768

However, the production method by adhesion has a problem that it is difficult to mass-produce underwear using three-dimensional adhesion because the process of three-dimensional adhesion takes time. For this reason, women's shorts account for the majority of underwear that consists only of adhesives, and boxer-type underwear is only sold with some sewn products.

In addition, underwear that does not use elastic cords has a problem that the position fixing force at the waist is weak and the upper part of the front body tends to slide down when worn.

Therefore, the present invention has been made in view of such a problem, and provides a comfortable bottom garment that reduces a feeling of oppression in the foot-operated portion and prevents the upper side of the front body from slipping down. With the goal. More specifically, we offer boxer type and low leg type underwear that suppresses parts as much as possible, simplifies production, reduces the feeling of pressure on the thigh, and prevents the upper side of the front body from slipping down without using rubber cords. The purpose is to do.

In order to solve the above problems, the underwear according to the present invention is underwear such as boxer type or low leg type shorts that uses elastic fabric for the body, and uses elastic cords for the waist and legs. It is characterized by the fact that both sides and the upper side of the front body form an inverted W shape when placed flat.

In addition, the fabric of the openings such as the waist and the footline of the underwear is not hem-treated and is characterized in that it is left uncut.

Furthermore, it is characterized in that the fabric pieces constituting the underwear are composed only by adhesion.

According to this, when the underwear is worn, both sides rise in the direction perpendicular to the ground, and the substantially V-shaped recess of the front body rises from an acute angle to an obtuse angle, and the back side of the underwear It stabilizes at a position that balances the position of the upper side. As the substantially V-shaped recess of the front body rises, an upward pulling force is applied to the inner crotch front part of the base of the thigh below the lowest point of the V-shape. Since the abdomen of the human body bulges forward from the base of the thigh, the upward pulling force is applied slightly diagonally forward and upward, and the adductor longus in the anterior inner thigh of the base of the thigh. The force that presses the adductor longus can be reduced. In addition, since the upper side of the front body is approximately V-shaped, the upper side of the front body slides down because the force that pulls the front body upward works more than the conventional one with the upper side of the front body straight. It can also be prevented.

As described above, according to the underwear according to the present invention, it is possible to realize a boxer type or low leg type underwear that reduces the feeling of pressure on the thigh and makes it difficult for the upper side of the front body to slide down without using a rubber cord. It becomes.

Also, in underwear that does not use rubber, the upper side of the front body may curl due to the shape of the abdomen. However, according to the underwear according to the present invention in which the upper side of the front body is V-shaped, the curling direction changes at the lowest point of the V shape, so that the curled part does not reach the full width of the upper side of the front body and is V-shaped. There is also the effect that the degree of curling can be suppressed compared to the one that is not shaped.

The underwear according to the present invention will be described based on the embodiment.

In the embodiment described below, a 2-way fabric having elasticity in both the warp direction and the weft direction is used for the front and rear body fabric. The composition of the fabric is generally nylon or polyurethane, but polyester may be used instead of nylon, or cotton or recycled fibers may be inserted or woven. The dough used for the body is a dough that does not need to be trimmed and does not fray even if it is used uncut. The front body and the back body are bonded using a urethane-based hot melt adhesive, but may be bonded using another adhesive such as PUR (PolyUrethaneReactive).

First, as the first embodiment, boxer type women's underwear will be described.

FIG. 1 is a development view of women's underwear according to the first embodiment. FIG. 2 is a front view of the women's underwear after assembly.

The women's underwear 1 of the first embodiment is composed of a body cloth 11 and a gusset cloth 12. The body fabric 11 uses a 2-way fabric woven from nylon threads and polyurethane threads that expands and contracts in both the warp and weft directions, and the gusset fabric 12 uses a fabric made of cotton only. The gusset fabric 12 is adhered to the body fabric 11 with a polyurethane-based hot melt resin.

The body cloth 11 is composed of a front body 13 and a back body 14. The upper side 10 of the front body, which is the upper side of the front body 13, is recessed in a substantially V shape. The front body 13 and the rear body 14 are provided with connecting

portions

15, 16, 17, and 18 for connecting to each other at both side ends thereof. The connection part 15 of the front body 13 and the connection part 17 of the back body 14 are combined and bonded with hot melt resin, and similarly, the connection part 16 of the front body 13 and the connection part 18 of the back body 14 are combined and hot. Women's underwear 1 is completed by adhering with melt resin.

As shown in the front view after the assembly of FIG. 2 is completed, the women's underwear 1 is a substantially V-shaped predecessor with both

side portions

19, 20 which are the side parts when the women's underwear 1 is laid flat after being assembled. Around the time, the upper side 10 and the upper side 10 form an inverted W shape. The upper side 10 of the front body, which is formed in a substantially V shape, has an acute angle as shown in FIG.

Here, the reason is that the shape composed of the

side portions

19 and 20 and the upper side 10 of the front body is expressed as an inverted W shape, that is, an inverted W shape, instead of an M shape. is there.

This is because, as shown in Fig. 3, the human body is most widened near the greater trochanter, which is the base of the foot, and narrows toward the waist. If the

side portions

19 and 20 on both sides form an M shape that is substantially perpendicular to the bottom of the gusset portion, the upper side 10 of the front body, which is the waist portion, is extended to the left and right in a small distance. Inevitably, the force that pulls the upper side 10 of the front body to the left and right is also weakened, so that P1 cannot rise upward. If P1 does not rise upward, the force for pulling up the front part of the foot carriage is naturally weakened, so that the force for pressing the adductor longus muscle is weakened and the effect of the present invention that it is difficult to slide down cannot be exhibited. It ends up.

The same applies to the angle at which the upper side 10 of the front body opens in a V shape, and if the angle at which the upper side 10 of the front body opens in a V shape is an obtuse angle of around 140 degrees, even if the force pulling the upper side 10 of the front body is large. Since the distance at which P1 rises upward is small, the force for pulling up the front portion of the footrest portion is also weakened, and the effect of the present invention cannot be exhibited so much.

In order to exert the effect better, it is desirable to set the opening angle in a V shape to an acute angle of 90 degrees or less. If the fabric is hard to stretch, a certain effect can be obtained even at an obtuse angle of about 120 degrees, so an appropriate angle should be selected depending on the fabric to be used.

If the shape consisting of the

side parts

19 and 20 and the upper side of the front body 10 is M-shaped, the underwear should be made small using a very elastic fabric, and the elasticity should be suppressed at the waist. It may be possible to achieve this by applying resin to the fabric, pasting the fabric, or changing the knitting structure. However, since a complicated fabric is used for the knitting structure, the number of processes is increased, and the underwear itself becomes a firm wearing feeling, it causes stress on the wearer's skin, and the gist of the present invention. Will deviate from.

As shown in Fig. 2, the women's underwear 1 after the assembly is completed is flat and does not have a three-dimensional structure. In addition, no elastic cord is used for the waist and the openings of the legs, and the edges of the fabric are not hem-treated. That is, it shows that processing is easy.

Further, in FIG. 2, the length of the upper side 22 of the back body of the back body 14 located on the back side after assembling the women's underwear is smaller than 1/2 of the assumed waist length of the wearer. By doing so, when the women's underwear 1 is worn, the upper side 10 of the front body is pulled to the left and right by the wearer's waist, and the lowest point P1 of the substantially V-shaped part of the upper side 10 of the front body is above. Pulled up in the direction. By pulling up the upper side 10 of the front body, the force of pulling upward is transmitted to the crotch part where the gusset cloth 12 is located and the leg extension part around the crotch part.

Normally, a force acts along the outer shape of the thigh on the fabric of the leg leg, so the combined force acts toward the center of the thigh. This force toward the center of the thigh presses the adductor longus muscle, giving a feeling of pain and causing discomfort when worn.

However, in this women's underwear 1, since the upper side 10 of the front body is pulled up, a force in the diagonally upward direction in the forward direction is also applied to the leg extension portion of the crotch portion, so that the force is applied toward the center of the thigh. The force is relieved, the pressure on the adductor longus muscle is reduced, the pain is relieved, and the discomfort when wearing is reduced.

The mechanism by which the force toward the center of the thigh is relaxed will be explained in detail.

FIG. 3 is a front view showing a state in which the women's underwear of the first embodiment is worn, and FIG. 4 is a side view thereof. FIG. 5 is a view looking up from slightly forward of the line BB of FIG. 4, and FIG. 6 is a view showing a cross section of the line AA of FIG. FIG. 7 is a diagram showing a vector of the force applied to P2.

As shown in FIG. 5, the point P2 at the front part of the inner thigh where the adductor longus muscle 30 is located is a corner rather than an arc shape. A force acts along the outer shape of the thigh on the leg extension of the women's underwear 1. When the acting force is represented by a vector, at the point P2, the vector 50 and the vector 51 act along the outer shape thereof. Then, the vector 52, which is a composite vector of the vector 50 and the vector 51, is generated, and a force is applied toward the center of the thigh. At this time, since the point P2 is closer to the corner than the other thighs, the force toward the center of the thigh is larger than the others, and the adductor longus muscle 30 at the point P2 is pressed, causing pain and discomfort. Is bringing.

However, in the women's underwear 1 of the first embodiment, since the force of pulling upward is applied to the front body 13, a force like the vector 53 shown in FIG. 6 is also applied to P2 of the front part of the inner thigh. Therefore, the final force is a composite vector of the vector 52 and the vector 53.

FIG. 7 shows these vectors viewed from diagonally behind and above.

The vector 54, which is a composite vector of the vector 50 and the vector 51, and the vector 53, which is a force vector 53 that pulls the front body 13 diagonally forward and upward, is a force applied to P2 when worn. Therefore, in P2, the force toward the center of the thigh, that is, the force that presses the adductor longus muscle 30, is the force from the vector 54 to the point on the vector 52 that is perpendicular to the vector 52. That is, the force for pressing the adductor longus muscle 30 is weaker than that of normal underwear by the amount of line segment 61 / (line segment 60 + line segment 61).

From the above, women's underwear 1 that does not cause discomfort in the thigh inner thigh is completed without using a complicated three-dimensional structure.

FIG. 8 is a front view of the women's underwear 1 of the first embodiment placed flat, and shows a state when the portion of P1 is pulled up to the vicinity of the upper side 22 of the back body of the back body 14. According to FIG. 8, it can be seen that as P1 rises upward, the foot pulling portion 31 opens a large mouth in the front surface, and the portion corresponding to P2 also rises upward in the front center. Then, since the foot pulling portion 31 near P2 has a shape protruding to the front portion of the inner crotch, the fabric is slackened. That is, since a space is generated in the portion where the adductor longus muscle 30 exists, the feeling of tightening can be alleviated.

Because the force to pull the front body 13 always works when it is worn, it is difficult for the front body 13 to slide down.

The size of each vector shown varies depending on the physical properties of the fabric used, but the orientation of each vector is approximately the same, so the action is the same.

In the case of a fabric that stretches well even with a weak force, it is advisable to attach a front cover to the front body 13 and adjust the stretch as in the second embodiment introduced below.

Next, the second embodiment will be described. The second embodiment is a boxer type underwear for men.

FIG. 9 is a development view of the men's underwear of the second embodiment. FIG. 10 is a front view of the men's underwear after assembly.

The men's underwear 100 of the second embodiment is composed of a front body 101, a back body 102, and a front pad 103. Similar to the first embodiment, the upper side 110 of the front body, which is the upper side of the front body 101, is recessed in a substantially V shape. The front pad 103 is bonded to the center of the front side of the front body 101 with a urethane-based hot melt.

The front body 101 and the rear body 102 are provided with connecting

portions

104, 105, 106, 107, 108, 109 for connecting to each other at both side ends and crotch portions, respectively. The connection portion 104 of the front body 101 and the connection portion 107 of the back body 102 are combined, and the connection portion 105 of the front body 101 and the connection portion 108 of the rear body 102 are combined and bonded with a urethane-based hot melt resin. Similarly, the men's underwear 100 is completed by combining the connecting portion 106 of the front body 101 and the connecting portion 109 of the rear body 102 and adhering them with a urethane-based hot melt resin. Further, as in the first embodiment, the elastic cord is not used for the opening of the waist portion and the leg pulling portion, and the hem treatment at the edge of the fabric is not performed.

The front view after the assembly is completed is shown in FIG. The front body 101 of the men's underwear 100 is not molded.

Similar to the first embodiment, in a state where the completed men's underwear 100 is placed flat, both

side portions

111 and 112, which are the side parts when the men's underwear is assembled flat, and a substantially V-shaped front body The upper side 110 and the upper side 110 form an inverted W shape.

With the completed men's underwear 100 laid flat, the length of the back body upper side 113 of the back body 102 located on the back side after assembling the men's underwear 100 is more than 1/2 of the waist size of the assumed wearer. Is also getting smaller. As a result, the upper side 110 of the front body of the front body 101 is pulled to the left and right when worn, and the lowest point P1'of the upper side 110 of the front body is pulled upward.

FIG. 11 corresponds to FIG. 5 in the first embodiment. FIG. 12 corresponds to FIG. 6 in the first embodiment. FIG. 13 corresponds to FIG. 7 in the first embodiment and is a diagram showing a vector of the force applied to P2'.

The direction of the vector toward the center of the thigh at the point P2'near the adductor longus muscle is almost the same as that of the first embodiment. As shown in FIG. 12, a force 153 that pulls the front body 101 upward, which is a feature of the men's underwear 100, is applied to this. In the case of a male, since there is a male genital 120, a force 154 that goes diagonally forward and downward is further applied.

The force applied to these points P2'is represented by a vector, and when a composite vector is created, it becomes as shown in FIG.

Similar to the first embodiment, FIG. 13 shows a view of these vectors viewed from diagonally rear and upper.

The vector has a three-dimensional structure, but it is difficult to understand if it is expressed in two dimensions. Supplementally, the

vectors

150, 151, 152 are in the same plane, the

vectors

152, 154, 155 are in the same plane substantially orthogonal to the above plane, and the

vectors

153, 155, 156 are the plane containing the vector 154. It is on the same plane with a slight deviation.

The force applied along the outer shape of the thigh is the vector 150 and the vector 151, and the force toward the center of the thigh is the vector 152 which is a composite vector of the vector 150 and the vector 151. This is the magnitude of the force of the conventional product in which the upper side of the front body of the front body is not formed in a V shape.

To this, the male genitals 120 exert a pulling force diagonally forward and downward like a vector 154, and the vector 152 is combined with the above composite vector, and a vector 155 is generated as a new composite vector at the point P2'. Will be done.

Then, since the force pulling the front body 101 upward works like the vector 153, the final force becomes like the vector 156 which is the composite vector of the composite vector 155 and the vector 153.

The vector 156 is a force that is substantially in the same plane as the vector 152 toward the center of the thigh and is directed in the opposite direction. Therefore, the force toward the center of the thigh is the force obtained by subtracting the vector 156 from the vector 152, and the force pressing the adductor longus muscle 30 is weakened.

Since the upper side 110 of the front body is constantly pulled upward, the sliding down due to the weight of the male genitals 120 is also minimized.

From the above, a men's underwear 100 that does not use rubber and has an excellent wearing feeling is formed, in which the upper side 110 of the front body does not slide down when worn, and the inner crotch part is not pressed to cause discomfort.

In the second embodiment, the front pad 103 is attached in order to suppress the downward tension of the front body 101 due to the weight of the male genitals 120, but the fabric used for the front body 101 has a large stretching force. In that case, the front pad 103 may be omitted. Further, in the second embodiment, the male genitals 120 of the front body 101 are not molded.

Due to the lack of molding, the shape of the male genitals 120 pulls the front body 101, and at point P2', a force is generated diagonally forward and downward, and the force that presses the adductor longus muscle 30 weakens. become. However, even if the front body 101 is not pulled by molding and the force in the diagonally front-down direction at the point P2'is almost eliminated, there is a force to pull the front body 101 upward, so that in the first embodiment As described above, the force for pressing the adductor longus muscle 30 is weaker than that of the conventional product.

Subsequently, the third embodiment will be described. The third embodiment is a boxer type underwear for men as in the second embodiment, and is different from the second embodiment in that the front pad portion is molded. Hereinafter, the differences will be mainly described.

FIG. 14 is a front view of the men's underwear according to the third embodiment after assembly. FIG. 15 is a side view of men's underwear in a state where one side of the foot-rolling portion is turned up.

When performing mold molding, as shown in FIG. 15, the bottom edge of the mold 140 is folded with the center of the front body and the center of the back body of men's underwear at both ends, and one of the legs is raised. It is configured to be located above the crotch line 141 that can be formed when it is folded. As a result, the scrotum of the male genitals naturally lowers the lower edge of the mold 140, creating a downward force.

Also, the shape of the mold 140 is not circular, but rather a gourd shape that narrows as it goes up. This is to make the shape of the penis of the male genitals closer so as not to create a wasted space, and to transmit the force applied to the lowest point P1'as evenly to the lower part of the front body as much as possible. ..

When worn, the upper side 110 of the front body of the front body pulls up the lowest point P1'upward. The lowest point P1'generates a force that radially pulls up the lower edge from the lowest point P1'. At this time, if the upper side of the mold 140 is wide, the dough of the mold 140 is, so to speak, loose, so that the pulling force is absorbed and is not transmitted to the lower part. As much as possible, the upper part of the mold 140 should be narrowed in order to transmit the force to the lower part. Then, in order to reduce the slack portion, the shape of the mold 140 should be similar to that of the penis of the male genitals.

As described above, in the underwear according to the present invention, the front and rear body fabrics are made of a fabric that expands and contracts in both directions, and the upper side of the front body is recessed in a substantially V shape to connect the front body and the back body. Create an underwear, and in a flat state, create a pattern so that both sides of the underwear and the upper side of the front body form an inverted W shape.

When wearing underwear constructed in this way, both sides rise vertically to the ground, and the approximately V-shaped recess in the front body rises from an acute angle to an obtuse angle, and the upper side of the back side of the underwear. It stabilizes at a position that is balanced with the position of.

As the substantially V-shaped part of the front body rises, a pulling force is applied to the anterior inner thigh at the base of the femur below the vicinity of the lower point of the V-shape. Since the abdomen of the human body bulges forward from the base of the thigh, the upward pulling force is applied slightly diagonally forward and upward, compressing the adductor longus muscle in the anterior part of the inner thigh of the thigh. It is possible to reduce the force to do.

In addition, since the upper side of the front body is approximately V-shaped, the upper side of the front body slides down because the force that pulls the front body upward is exerted compared to the conventional one in which the upper side of the front body is straight. Can also be prevented.

The underwear according to the present invention has been described above based on the embodiments, but the present invention is not limited to this, and various design changes can be made within the range where the object of the present invention can be achieved and the gist of the invention is not deviated. Are possible, all of which are within the scope of the present invention.

For example, in each of the above embodiments, sewing is not used at all, but the front body and the back body may be connected by sewing, and the effect of the present invention can be exhibited even by this.

The underwear according to the present invention is useful as bottom clothing, and is suitable as boxer type and low leg type bottom clothing regardless of gender.
