Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing, and more specifically, to a sports bra. Background Technology
[0002] like Figure 11 — Figure 12 As shown, existing one-piece knit sports bras are formed using a single knitting structure, such as plain weft knit. In plain weft knit, loops are formed sequentially by yarn in a horizontal direction, resulting in a relatively loose connection between loops. However, because the loop structure of plain weft knit is relatively simple, the interaction force between loops is small. Therefore, although sports bras formed by plain weft knit are relatively soft, during exercise, the chest area cannot effectively fix the breasts in the proper position due to the body's movements. Furthermore, the cleavage area, because it uses the same plain weft knit structure as the chest area, suffers from insufficient support, leading to the formation of accessory breast tissue. Similarly, the underarm and side bulge areas, using the same plain weft knit structure, also suffer from insufficient support, causing the breasts to shift laterally. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sports bra. Based on the weft-knit fabric of the sports bra, a honeycomb structure is gradually formed in the underband area, creating a honeycomb structure that transitions from dense to sparse towards the chest, thus preventing the breasts from shifting upwards during exercise. A honeycomb structure is also gradually formed in the cleavage area, creating a honeycomb structure that transitions from dense to sparse towards the chest, allowing the sports bra to better conform to the breast curve and provide lateral support, thereby reducing the formation of accessory breast tissue. A honeycomb structure is also gradually formed in the back side panel area, creating a honeycomb structure that transitions from dense to sparse towards the spine, thus enhancing the overall stability of the sports bra and preventing it from shifting during exercise. Ribs are added to the side panel area; the elastic distribution of the ribs allows the sports bra to better gather the breasts inwards, reducing pulling on the breast tissue and providing more stable support, preventing the breasts from shifting during exercise.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sports bra, comprising a front and a back, the front of the sports bra including a chest area, the chest area including a cleavage area and a side shank area on both sides and an underband area at the bottom, the bottom end of the cleavage area being connected to one side of the side shank area, the two ends of the underband area being connected to one side of the side shank area respectively, the side shank area extending laterally from the front of the sports bra to the back of the sports bra, the bottom surface of the underband area being connected to the hem, the back of the sports bra including a back shank area, the back shank area including two side panels, the two side panels being connected to one side of the side shank area respectively.
[0005] The present invention is further configured such that the bending area includes a first bending area, a second bending area, and a third bending area, wherein the first bending area, the second bending area, and the third bending area are sequentially fitted together from left to right.
[0006] The present invention is further configured such that the lowering area includes a first lowering area, a second lowering area, and a third lowering area, wherein the first lowering area, the second lowering area, and the third lowering area are arranged in a vertically attached manner.
[0007] The present invention is further configured such that the edge area includes a first edge area, a second edge area, and a third edge area, and the first edge area, the second edge area, and the third edge area are sequentially attached to each other on the left and right sides.
[0008] The present invention is further configured such that the length of the third region of the bend area is greater than that of the second region of the bend area, and the length of the second region of the bend area is greater than that of the first region of the bend area.
[0009] The present invention is further configured such that the middle of the first area of the lowering zone is semi-circular, and the middle of the second area of the lowering zone and the third area of the lowering zone is arc-shaped.
[0010] The present invention is further configured such that the chest area and the posterior ventral area are made of a first fabric, the lateral ventral area is made of a seventh fabric, and the hem is made of an eighth fabric.
[0011] The present invention is further configured such that the first region of the bending area is made of a fifth fabric, the second region of the bending area is made of a sixth fabric, and the third region of the bending area is made of a fourth fabric.
[0012] The present invention is further configured such that the first area of the undercut zone is made of a second fabric, the second area of the undercut zone is made of a third fabric, and the third area of the undercut zone is made of a fourth fabric.
[0013] The present invention is further configured such that the first area of the edge area uses a fifth fabric, the second area of the edge area uses a sixth fabric, and the third area of the edge area uses a fourth fabric.
[0014] The beneficial effects of this utility model are:
[0015] Based on the integrated knitting of the sports bra, a honeycomb structure is gradually formed in the underband area. The tight honeycomb structure at the bottom prevents the breasts from shifting upwards during exercise. A honeycomb structure is also gradually formed in the cleavage area, allowing the edges to better wrap around the breasts. This makes the sports bra fit the breast curve better, thus reducing the appearance of accessory breast tissue. A honeycomb structure is also gradually formed in the back edge area, which enhances the overall stability of the sports bra and makes it less likely to shift during exercise.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figure 1 — Figure 10 As shown, a sports bra includes a front and a back. The front of the sports bra includes a chest area 1. The chest area 1 is made of a first fabric. The first fabric has a weave cycle of 4 rows of loops. Each row of loops includes two yarns. The face yarn is made of 70D / 68F nylon, and the back yarn is made of 40D bare spandex + 40D / 34F nylon. The two yarns in each row of loops are both weft-knitted. This weft-knitted weave reduces the interaction force between the yarns in the chest area 1, making the chest area 1 relatively soft and thus not increasing the pressure on the chest, thereby maintaining the comfort of the bra.
[0031] The chest area 1 includes the two side bend areas 11 and lateral flank areas 13, and the lower flank area 12 at the bottom. The bend areas 11 include a first bend area 111, a second bend area 112, and a third bend area 113. The first bend area 111 uses a fifth fabric, which has a weave cycle of 10 loops. Each loop includes two yarns. The face yarn is 70D / 68F nylon, and the base yarn is a loose-covered yarn made of 40D bare spandex and 40D / 34F nylon. In the first to sixth warp rows of the first and sixth loop rows, the two yarns in each warp are woven in loops. In the first to third warp rows of the second to fifth loop rows, the two yarns in each warp are woven in loops. In rows 4-6, the base yarn of each row is looped, and the face yarn is floated. In rows 1-3 of the 7th-8th loop rows, the base yarn of each row is looped, and the face yarn is floated. In rows 4-6 of the 7th-8th loop rows, the two yarns in each row are looped. The second area 112 of the bend zone uses the sixth fabric, which has a weave cycle of 16 loop rows. Each loop row includes two yarns. The face yarn is 70D / 68F nylon, and the base yarn is a loose-covered yarn made of 40D bare spandex + 40D / 34F nylon. In rows 1-4 and 9-12, the two yarns in each row are looped. In rows 1-3 of the 5th-8th loop rows, each... The two yarns in each warp are woven in loops. In the 4th to 6th warps of the 5th to 8th warp rows, the base yarn in each warp is looped, and the face yarn is a float. In the 1st to 3rd warps of the 13th to 16th warp rows, the base yarn in each warp is looped, and the face yarn is a float. In the 4th to 6th warps of the 13th to 16th warp rows, the two yarns in each warp are woven in loops. The third area 113 of the bend zone uses a fourth fabric. The fourth fabric has an 18-warp loop structure, with each warp row consisting of two yarns. The face yarn is made of 70D / 68F nylon, and the base yarn is made of 40D bare spandex + 40D / 34F nylon. In the 1st to 6th warp rows and the 1st to 8th warps of the 10th to 15th warp rows, the two yarns in each warp are woven in loops. All yarns are woven in loops. In the 1st to 5th warps of the 7th to 9th loop rows, the two yarns in each warp are woven in loops. In the 6th to 8th warps of the 7th to 9th loop rows, the base yarn in each warp is looped, and the face yarn is floated. In the 1st to 3rd warps of the 16th to 18th loop rows, the base yarn in each warp is looped, and the face yarn is floated. In the 4th to 8th warps of the 16th to 18th loop rows, the two yarns in each warp are woven in loops. Because in the 10th loop row of the fifth fabric, both yarns are woven in loops, forming a 2-loop row, while the base yarn is looped and the face yarn is floated, forming an 8-loop row. In the 16th loop row of the sixth fabric, both yarns are woven in loops, forming an 8-loop row, while the base yarn is looped.The face yarn is a float yarn with 8 loops. In the fourth fabric with 18 loops, both yarns are woven into loops, forming 12 loops. The base yarn is looped, and the face yarn is a float yarn with 6 loops. In the fifth, sixth, and fourth fabrics, the base yarn is looped, and the face yarn floats are woven into honeycomb patterns. Therefore, the interval between two honeycombs in the fifth fabric is 1 loop, the interval between two honeycombs in the sixth fabric is 4 loops, and the interval between two honeycombs in the fourth fabric is 6 loops. Therefore, the fifth fabric... The honeycomb spacing in the middle fabric is smaller than that in the sixth fabric, which in turn is smaller than that in the fourth fabric. Both the fifth and sixth fabrics have honeycomb formations consisting of three vertical rows in a four-way coil row, while the fourth fabric has three vertical rows in a three-way coil row. Therefore, the honeycomb structure in the fifth and sixth fabrics is larger than that in the fourth fabric, resulting in a higher density in the fifth fabric compared to the sixth fabric. The first, second, and third areas of the bend area (111, 112, and 113) are sequentially positioned, with the first area (111) near the armpit and the third area (113) near the chest. This creates a gradient pressure in the bend area (111), causing the honeycomb structure to transition from dense to sparse towards the chest. The tighter honeycomb structure at the edges allows the sports bra to better wrap the chest, conforming better to the chest curve. Furthermore, the fifth fabric in the first area (111) of the bend area increases pressure on the accessory breast area, suppressing excess fat and reducing its formation. The length of region 113 is greater than that of the second curved region 112, and the length of the second curved region 112 is greater than that of the first curved region 111. The number of honeycomb cells and the spacing between them in the first curved region 111, the second curved region 112, and the third curved region 113 create a gradual change. This gradual change in tightness allows the sports bra to better conform to the chest without causing pressure, ensuring freedom of movement. Furthermore, the increased honeycomb structure enhances breathability under the armpits, further improving the comfort of the sports bra.
[0032] The bottom end of the bend zone 11 connects to one side of the side shank zone 13. The side shank zone 13 uses the seventh fabric, which has a four-row stitch cycle. Each row of stitches includes a 70D / 68F nylon face yarn and a 40D bare spandex + 40D / 34F nylon loose-covered yarn base yarn. In one cycle, the two yarns in the first to fourth warp rows of the first, second, and fourth rows are knitted in loops, the two yarns in the first to third warp rows of the third row are floats, and the two yarns in the fourth warp row of the third row are knitted in loops. This is because the four rows of stitches in the first fabric are all plain knit, while the seventh... The first to third rows of the third row of the fabric are floats, but the coils of the first to third rows of the second row of the fabric interact with the first to third rows of the fourth row of the fabric. This makes the side gusset area 13 of the seventh fabric more elastic and tight. The side gusset area 13 extends laterally from the front of the sports bra to the back of the sports bra, thus enhancing the stability of the side of the sports bra and effectively preventing the sports bra from shifting during activities. At the same time, it can evenly distribute pressure, reduce marks and pressure. Furthermore, the bottom end of the gusset area 11 is connected to one side of the side gusset area 13, which can also restrict each other, thereby reducing the displacement of the gusset area 11 due to movement.
[0033] The two ends of the undercut zone 12 are connected to one side of the respective lateral undercut zone 13. The undercut zone 12 also includes a first undercut zone area 121, a second undercut zone area 122, and a third undercut zone area 123. The first undercut zone area 121 uses a second fabric, which consists of 12 loops forming a weave cycle. Each loop includes a 70D / 68F nylon face yarn and a 40D bare spandex + 40D / 34F nylon loose yarn base yarn. In the 12 loops, in the 1st to 4th warp of the 1st to 6th loops, both yarns are woven into loops. In the 5th to 8th warp of the 1st to 6th loops, the base yarn is looped, and the face yarn is a float. In the 1st to 4th warp of the 7th to 8th loops, the base yarn... The yarn is looped, with the face yarn as a float. In the 5th to 8th warp rows of the 7th-8th loop rows, both yarns are woven into loops. The second area 122 of the underlayment uses a third fabric, which consists of 14 loop rows forming a weave cycle. Similarly, each loop row includes a 70D / 68F nylon face yarn and a 40D bare spandex + 40D / 34F nylon loose-covered yarn base yarn. In the 14th loop rows, in the 1st to 4th loop rows and the 1st to 6th warp rows of the 8th to 11th loop rows, both yarns are woven into loops. In the 1st to 3rd warp rows of the 5th to 7th loop rows, both yarns are woven into loops. In the 4th to 6th warp rows of the 5th to 7th loop rows, the base yarn is looped, and the face yarn is a float. The 12th to 14th loop rows... In the first three rows, the base yarn is looped, and the face yarn is floated. In the fourth to sixth rows of the 12th to 14th loop rows, both yarns are woven into loops. The third area 123 of the undercut zone uses the same fourth fabric as the third area 113 of the bend zone. This is because the base yarn in the second, third, and fourth fabrics is looped, and the face yarn is floated, forming a honeycomb structure. In the second fabric, the honeycomb weave is 6 loop rows and 4 columns in size, with no gap between the two honeycombs. In the third fabric, the honeycomb weave is 3 loop rows and 3 columns in size, with a 4 loop row gap between the two honeycombs. In the fourth fabric, the honeycomb weave is 3 loop rows and 3 columns in size, with a 6 loop row gap between the two honeycombs. Therefore... The first, second, and third areas 121 and 122 of the underbust area 12 also form a honeycomb gradient, with the first area 121 having the most honeycomb structure. Therefore, the first area 121 is the tightest. The center of the first area 121 is semi-circular, while the centers of the second and third areas 122 and 123 are arc-shaped. Thus, the first area 121 is the tightest and has the largest area, providing support for the breasts and limiting the shifting of the sports bra during exercise. Furthermore, the underbust area 12 and the cleavage area 11 provide multi-directional restriction for the breasts, ensuring they remain within the space enclosed by these areas, increasing shaping and preventing sagging.The underband areas 121, 122, and 123 are sequentially fitted together, creating a gradually decreasing density from the bottom of the chest towards the bust. This gradual transition between the underband area 12 and the support area 11 allows the sports bra to accommodate various bust sizes and provides better support and lift. Furthermore, the honeycomb structure increases breathability at the bottom of the bust, promoting sweat evaporation and reducing sweat buildup, thus maintaining the bra's comfort.
[0034] The reverse side of the sports bra includes a back section 2, which comprises two side panels 21. The back section 2 uses a first fabric with a plain weave. Each side panel 21 includes a first side panel area 211, a second side panel area 212, and a third side panel area 213. The first side panel area 211 uses a fifth fabric, the second side panel area 212 uses a sixth fabric, and the third side panel area 213 uses a fourth fabric. The side panels 21 and the cleavage area 11 use the same fabric. The two side panels 21 are connected to one side of the side panel area 13. Therefore, the first area 211 of the side panel is connected to one side of the side panel 13, while the third area 213 of the side panel is close to the spine. This makes the honeycomb structure form a structure that changes from dense to sparse from both sides of the back towards the spine, and makes the chest tightly wrapped, enhancing the overall stability of the sports bra and making it less likely for the bra to shift during exercise. The first area 211, the second area 212, and the third area 213 of the side panel are set together in sequence to form a gradual honeycomb structure, which allows the pressure of the sports bra to be dispersed, so as not to produce a feeling of pressure.
[0035] The bottom of the underband 12 is connected to the hem 14, which uses the eighth fabric. The eighth fabric has a four-way loop as one weave cycle. Each loop includes a 70D / 68F nylon face yarn and a 40D bare spandex + 40D / 34F nylon back yarn. The first to fourth warp of the second and fourth loops are all woven into loops. The first to third warp of the first and third loops are floats. The fourth warp of the first and third loops is woven into loops. Therefore, the hem 14 is tighter than the side flank area 13, so that the hem 14 provides more stable support for the chest and reduces discomfort caused by chest movement. The sports bra is made of one-piece knitting. Each area is distributed with different tissue structures, which enhances the wrapping and shaping effect of the chest, reduces the restriction on the body and effectively reduces exercise fatigue.
