Description

Double Y-shaped shoulder straps and sports underwear

technical field

The application relates to the field of underwear, in particular to a double Y-shaped shoulder strap and a sports underwear.

Background technique

With the improvement of the quality of life, fitness exercises have become a fashion and have entered the lives of urban women. Due to the physiological characteristics of women, breasts are glandular organs hanging on the pectoralis major without bone and muscle support. When exercising, if you don’t wear underwear, your breasts will vibrate and shake involuntarily, and the elastic fiber tissue in the breasts will be permanently damaged, which will easily cause breasts to sag, affecting the appearance and movement, and there will be pain after exercise. If the breasts are not supported and protected by long-term high-volume exercise, it will also cause pectoralis major muscle tear. Therefore, sports underwear that can fix breasts and have good shockproof effect has emerged at the historic moment.

Sports underwear refers to the special underwear that women wear when they are engaged in specific sports, also known as sports bra. As the name suggests, sports underwear is designed and manufactured to prevent women's breasts from being hurt during exercise and fitness. Compared with ordinary underwear, it is shorter, tighter and more elastic. It has the function of moisture absorption and perspiration. When the skin, muscles and bones are stretched and contracted, it can protect the breasts, give the breasts a certain support, control the displacement of the breasts, and prevent the breast muscles from collapsing. The injury of ligaments can reduce the sports injury to the breast caused by women's sports. It can provide more comfort and protection while exercising.

In addition to aesthetics, sports bras also need to be comfortable and functional. Some sports bras have little supporting effect and cannot effectively restrict the movement of the breasts during exercise, resulting in movement and damage to the breasts. Therefore, the function of controlling breast movement during exercise is one of the important features of sports bras; some sports bras are under high pressure, causing exercisers to have difficulty breathing, poor blood circulation, and even induce breast diseases; Sliding, movement of shoulder straps, and difficulty in undressing; some sports bras have damp skin after exercise, and sweat cannot be discharged in time after exercise, causing athletes to have thermal and humidity comfort problems such as a sticky feeling; there are also some sports bras that are used in fabrics It is unreasonable on the surface, causing the sportsman to feel uncomfortable after wearing it, etc., which bothers the sportsman. Therefore, the present invention improves on the above problems existing in the prior art.

In addition, when the shoulder straps are connected to the cup ears and waist of the underwear, they are superimposed and stitched, which will increase the thickness of the stitched part. If the stitching is not handled properly, it is easy to wear the skin and cause discomfort.

Contents of the invention

In view of this, the object of the present invention is to overcome the deficiencies of the prior art and provide a double Y-shaped shoulder strap that can improve the production efficiency and comfort of sports underwear.

In addition, the invention also provides a sports underwear prepared based on double Y-shaped shoulder straps.

In order to solve the above-mentioned technical problems, the present invention adopts following scheme to realize:

In the prior art, except for the underwear manufactured by integral molding, other underwears are made by stitching multiple parts of the underwear together to form the finished underwear. The connection of shoulder straps, cups, and side sleeves of traditional underwear is superimposed and sutured. This method brings the following disadvantages: the suture is not smooth, forming a local tip, and it is easy to cause damage to human skin without any treatment. Chafing damage, reducing comfort. Moreover, under long-term friction at the seams, the seams are easy to loosen, which not only affects the appearance, but also reduces the life of the underwear. In order to improve this shortcoming, in the prior art, the tip of the suture will be further processed, such as by crimping the suture, that is, embedding the tip of the suture by additional means to reduce the hardness of the suture, Thereby reducing the friction on the human body. However, this improvement will still cause local bulges, and the seams are not smooth, which is enough to reduce the comfort level for tight-fitting clothing such as underwear. For this reason, the present invention improves shoulder straps, and its improved structure is that the shoulder straps include superficial elastic webbing and inner layer elastic webbing that are superimposed and sewed together, and the outer elastic webbing and inner elastic webbing are sewn together along the length direction of the shoulder straps. Connected so that the surface elastic webbing and the inner elastic webbing on both sides of the stitched part can be separated from each other, thereby forming a double Y-shaped shoulder strap. The shoulder strap is modified in this way, when the shoulder strap is stitched and connected with other parts, other parts can be directly embedded between the surface layer elastic webbing and the inner layer elastic webbing, so the formed seam will not form a local tip. Although this method will also cause local bulges, due to the covering of the surface elastic webbing and the inner layer elastic webbing, the transition of the raised parts is smoother, thus reducing the foreign body feeling of the user. In addition, this structure avoids the use of additional means to process the seams when sewing underwear, which can greatly improve production efficiency. The seams will not loosen due to friction, which not only improves comfort, but also enhances durability.

In order to facilitate the suture connection of the shoulder straps to other parts of the underwear, the stitching position is centrally arranged along the width direction of the shoulder straps. In this way, the size of the openings on both sides of the shoulder strap is the same. When sewing, it is not necessary to choose the side with a larger opening or the side with a smaller opening, which avoids production errors, reduces the defective rate, and improves production. efficiency. In addition, when the shoulder straps are stretched, the overall force of the shoulder straps is more even, and the contact area with the human body is the area of the shoulder straps. There will be no phenomenon that one side is too stressed and the other side is tilted, which improves wearing comfortability.

Since in the present application, the stitching parts of the shoulder straps are stitched together in the middle along the length direction of the shoulder straps, therefore, the setting of the stitching length along the width direction of the shoulder straps is more important. When the stitching length in the width direction is too short, when the shoulder straps are stretched and deformed, the surface elastic webbing and the inner elastic webbing on both sides of the shoulder straps are easy to warp, which does not play a role in supporting tension. , the contact area with the human body is mainly the suture part, which will greatly increase the pressure on the human body and reduce the comfort; if the suture length in the width direction is too long, there will be insufficient suture space with other underwear parts. It is easy to be inaccurate in positioning and reduce the yield rate. Therefore, in the present application, the knitting length of the stitched part along the width direction of the shoulder strap is 1/3~2/3 of the width of the shoulder strap.

The shoulder straps of the underwear are responsible for lifting the entire chest. When the user is exercising, the shoulder straps form a dynamic contact with the human skin, and the shoulder straps deform to adapt to changes in the human body. The deformation of the shoulder straps will generate internal stress, thereby Restrain the contact parts with the human body, that is, generate contact pressure that oppresses the human body, especially when the shoulder straps have a large deformation range, the sense of restraint is stronger. Therefore, in order to improve the comfort of the shoulder belt and the contact part, a suede layer is provided on the surface of the elastic webbing of the inner layer, that is, a suede layer is provided on the side that is in contact with the skin. To a certain extent, the comfort of wearing is improved, and the shortcoming of indentation caused to local skin can be overcome in particular.

When the human body is exercising, the heat-humidity balance between the skin and the human body will be broken. If the shoulder straps cannot be ventilated and moisture-permeable, the comfort will inevitably be reduced. Although the contact area between the shoulder straps and the human body is smaller than that of other parts, the pressure generated by the shoulder straps on the human body is relatively large. If the shoulder straps are not treated, the wearing comfort cannot be improved, especially for sports underwear. In this application, since the suede layer is provided, it is equivalent to increasing the thickness of the shoulder straps, which theoretically reduces the breathable and moisture-permeable effect. Therefore, in this application, the suede layer includes multiple sections of suede The surface is composed of multiple sections of suede, so that a breathable and moisture-permeable channel is formed between each section of suede, so that the heat and moisture generated by the skin can be drained away through this channel. In addition, due to the lack of elasticity of the suede layer, it will significantly affect the elasticity of the inner elastic webbing, and this shortcoming can be overcome by the multi-segment suede structure, which can maintain the elastic performance of the inner elastic webbing to the maximum extent and avoid the damage caused by suede. Layer settings reduce the elastic effect.

As mentioned above, in addition to the openings formed on both sides of the shoulder straps, at least one of the ends of the shoulder straps along the length direction of the shoulder straps can be separated from the surface elastic webbing and the inner elastic webbing, which further improves the distance between the shoulder straps and other parts. sewing efficiency.

A sports underwear, comprising:

The main body of the cup is divided into a left cup part and a right cup part;

The girth connected to the main body of the cup is divided into a left girth connected with the left cup and a right girt connected with the right cup;

The elastic closed binding part connected to the lower edge of the main body of the cup and the lower edge of the girdle;

The above-mentioned double Y-shaped shoulder straps are divided into left shoulder straps and right shoulder straps;

One end of the left shoulder strap is connected to the left cup, the other end is connected to the end of the right girdle, and the end of the right girdle is embedded between the surface elastic webbing and the inner layer elastic webbing of the left shoulder strap;

One end of the right shoulder strap is connected to the right cup, and the other end is connected to the end of the left girdle, and the end of the left girdle is embedded between the surface elastic webbing and the inner layer elastic webbing of the right shoulder strap.

During the user's exercise, the breasts swing from side to side in an "∞" shape, instead of shaking up and down in ordinary actions (such as walking). This phenomenon is especially true in high-intensity sports, such as running and skipping rope. Swinging from side to side can easily damage the breast fibers, causing irreversible damage, leading to adverse consequences such as breast sagging. Therefore, how to prevent breasts from swinging left and right is a more important point for a sports bra. Therefore, in the present application, the above-mentioned problems are overcome by setting the left shoulder strap and the right shoulder strap crosswise. When the breast swings to the left, the right hip is stretched, and the left shoulder girdle pulls the right hip. Through such a structure, firstly, it can prevent the shoulder girdle from falling off, and secondly, it can limit the swing of the breast to the greatest extent, control the displacement of the breast, and avoid the damage of the breast muscles and ligaments.

In the sports underwear of the present application, the ends of the left side part and the right side part are separated rather than connected together, the left side part is pulled by the right shoulder strap, and the right side part is pulled by the left shoulder strap. This structure has the following advantages : In the course of exercise, the user's breasts are swinging from side to side, because the elastic closed shape binding part of the underwear will support the breasts and prevent the bottom edge of the underwear from sliding upwards, so that it will have a certain elastic binding force. At this time, the ends of the left gizzard and the right gizzard are connected together. When the breast swings to the left, the deformation and stretching of the right gizzard and the deformation and stretching of the binding part exert the binding force on the human body and greatly exceed that of simple binding. The restraint force exerted by the body can easily cause chest tightness and even vomiting in the user. In this application, although the left side and the right side are not connected, the fixing effect of the underwear will not be reduced by pulling the right shoulder strap and the left shoulder strap obliquely respectively.

As mentioned above, during exercise, the user's breasts swing left and right in a "∞" shape. In addition to the left and right swings, there is also a process of transitioning from up and down swings to left and right swings. In some extreme cases, when swinging up and down, the sports bra has Chance to swipe up so that the breasts are exposed. In order to overcome this problem, it is necessary to strengthen the elastic restraint of the binding part, but the adverse effect caused by this is that it will cause chest tightness. Because the probability of these extreme situations is low, some manufacturers do not pay too much attention when preparing underwear . In the present application, by setting the elastic connecting belt, it is divided into a left elastic connecting belt and a right elastic connecting belt; one end of the left elastic connecting belt is connected to the upper edge of the left gizzard, and the other end is embedded in the surface elastic webbing of the left shoulder strap and The inner layer elastic webbing is stitched and connected; one end of the right elastic webbing is connected to the upper edge of the right girdle, and the other end is embedded in the seamed connection between the surface elastic webbing of the right shoulder strap and the inner layer elastic webbing. Through the above structure, the fixing effect of the underwear is better. When the breast swings downward to the left, the left shoulder strap and the right elastic connecting belt can lift the right hip obliquely upwards, which is different from the traditional horizontal restraint. In addition to preventing the underwear from sliding up, it can also reduce chest tightness.

In this application, since one of the functions of the left elastic connecting belt and the right elastic connecting belt is to realize the oblique upward pulling of the left and right glutes, when an acute angle is formed between the left elastic connecting strip and the left glutes, The included angle makes the left elastic connecting belt incline to the right side; the right elastic connecting belt forms an acute angle with the right side, so that when the right elastic connecting belt is inclined to the left side, Best for lifting. Furthermore, the lifting of the left gizzard by the left elastic connecting belt is realized by the left shoulder strap, and the lifting of the right gizzard by the right elastic connecting belt is realized by the right shoulder strap. The elastic connection belt and the right shoulder belt are located on the same side, so under the action of the left elastic connection belt and the right elastic connection belt, under certain circumstances, the left shoulder belt Under the influence of the elastic connecting belt, there is a certain chance of loosening of the shoulder belt and the right shoulder belt. In this application, by setting the included angle as an acute angle, in addition to improving the lifting effect of the waist, it can also prevent the shoulder belt from loosening.

Preferably, the connection point between the left elastic connecting belt and the left gizzard is 3-8 cm away from the end of the left gizzard; the connecting point between the right elastic connecting belt and the right gizzard is 3-8 cm away from the end of the right gizzard. The left elastic connecting belt and the right elastic connecting belt should not only realize the lifting of the left gizzard and the right gizzard, but also prevent the shoulder straps from falling off. Through the adjustment of the above structure, the connection point/ The connection point between the right elastic connecting belt and the right shoulder belt should not be too high to increase the pressure applied to the shoulder, nor too low to reduce the lifting effect.

The upper edge of the left gizzard and the right gizzard is longer than the lower edge, so that the intersection point formed by the left shoulder strap and the right shoulder girdle is located 1-3 cm above the vertical direction of the left gizzard and the right gizzard. Since the shoulder belt needs to lift the gizzard obliquely upward, the ends of the left gizzard and the right gizzard are set to be inclined. Through the adjustment of the above structure, when the shoulder strap pulls the gizzard, it is along the shoulder belt. Stretching is achieved in the length direction to avoid lateral slippage of the shoulder straps, making the underwear more secure.

Compared with the prior art, the present application has the following beneficial effects: In the present application, the double Y-shaped shoulder straps are formed by the surface elastic webbing and the inner elastic webbing, so that the production efficiency can be greatly improved when sewing underwear. The comfort is improved by setting the suede on the surface of the elastic webbing of the inner layer; the suede is arranged in a multi-section structure to ensure that the resilience of the elastic webbing of the inner layer is not affected. Through the improvement of the sports underwear, the sports underwear is more suitable for women. It has a superior fixing effect and can avoid chest tightness caused by excessive restraint.
