Description

Technical Field

[0001] This utility model belongs to the field of clothing technology, specifically relating to an elastic adjustable combination strap suitable for clothing with bras. Background Technology

[0002] With the development of clothing technology, existing technologies have achieved integrated designs of bras and garments, such as lingerie and vests with built-in bras. These garments typically include two cups and a connecting strap (also called a back strap). This connecting strap is mainly used to connect the two cups to better provide coverage and support for the breasts. For example, Chinese patent CN204969506U discloses a bra, which also mentions that the second connecting end of the left cup is connected to the second connecting end of the right cup via a connecting strap. However, to meet the needs of wearers with different body shapes and to ensure the comfort and fit of these garments, this connecting strap is often designed to have a certain degree of elasticity.

[0003] However, existing elastic band designs have an inherent drawback. While these bands initially conform well to the wearer's body shape, over time, especially with frequent wear and washing, the elastic material in the bands gradually loses its original elasticity due to fatigue and aging. This change causes the bands to loosen, making the bra overall looser and no longer conforming to the wearer's body curves, thus reducing the bra's support and comfort.

[0004] Furthermore, due to individual differences, different wearers have varying needs regarding the tightness and support of underwear. Traditional elastic band designs often lack sufficient adjustment space, making it difficult to meet the personalized needs of all wearers. This limitation is particularly pronounced for women who seek a more snug fit and supportive effect.

[0005] Therefore, there is an urgent need for a flexible and adjustable combination bra strap suitable for bra-wearing garments. Summary of the Invention

[0006] To address the problems in related technologies, this utility model proposes an elastic adjustable combination strap suitable for bra-integrated garments, overcoming the aforementioned technical issues in existing technologies. This utility model designs the sub-elastic strap and the main elastic strap into a combination strap, allowing for precise adjustment of the tightness of the back of the bra-integrated garment according to individual body shape and tightness requirements. This not only improves wearing comfort but also ensures a close fit between the combination strap and the back skin, reducing discomfort caused by looseness or tightness.

[0007] The technical solution of this utility model is implemented as follows: an elastic adjustable combination back strap suitable for bra-wearing garments, including a female elastic back strap, which is used to connect two symmetrically arranged bra cups. The female elastic back strap is located on the back of the bra-wearing garment, and the inner side of the female elastic back strap is used to contact the skin on the back.

[0008] The inner side of the main elastic shoulder strap is provided with a sub-elastic shoulder strap for adjusting its tightness, and the sub-elastic shoulder strap and the main elastic shoulder strap are arranged side by side, inside and outside; the first and last ends of the sub-elastic shoulder strap are respectively connected to the inner side of the main elastic shoulder strap.

[0009] The width of the sub-elastic shoulder strap is smaller than the width of the mother elastic shoulder strap;

[0010] It should be noted that when worn, because the sub-elastic shoulder strap and the main elastic shoulder strap are arranged side by side inside and outside, and the sub-elastic shoulder strap is narrower, the sub-elastic shoulder strap is always covered by the main elastic shoulder strap and will not exceed the coverage area of ​​the main elastic shoulder strap.

[0011] The sub-elastic shoulder strap is slidably connected to a length adjustment buckle, and the tightness of the main elastic shoulder strap can be adjusted by lengthening or shortening the sub-elastic shoulder strap;

[0012] The elasticity of the sub-elastic shoulder strap is greater than that of the mother elastic shoulder strap.

[0013] Furthermore, the elastic back strap has a double-layer structure without a back buckle.

[0014] Furthermore, the mother elastic shoulder strap includes an inner and outer skin-adhering layer and a surface fabric layer, and the child elastic shoulder strap is disposed on the skin-adhering layer; one side of the skin-adhering layer is a skin-adhering and non-slip surface.

[0015] Furthermore, the skin-adhesive layer includes two positioning portions, each of which contains positioning cartilage; when worn, each positioning portion is in close contact with the underarm skin; the first and last ends of the sub-elastic shoulder strap extend to the positioning portions on both sides respectively.

[0016] Furthermore, the first and last ends of the sub-elastic shoulder strap are movably connected to the positioning part via detachable connecting buckles;

[0017] Furthermore, each of the positioning parts is provided with a shoulder strap connection point, and the two shoulder strap connection points are located on the same horizontal line; the first and last ends of the sub-elastic shoulder strap are respectively connected with buckles, which are used to engage with the shoulder strap connection points.

[0018] Furthermore, the first and last ends of the sub-elastic shoulder strap are fixedly connected to the positioning part by adhesive or sewing.

[0019] Furthermore, the fabric layer and the skin-adhesive layer are bonded together along their upper and lower edges to form an upper portion and a lower portion, respectively; the fabric layer and the skin-adhesive layer form a non-bonded cavity between the upper portion and the lower portion.

[0020] Furthermore, the sub-elastic back strap has an elastic structure with inner and outer double layers bonded together.

[0021] Furthermore, both the sub-elastic shoulder strap and the mother elastic shoulder strap are made of non-slip fabric;

[0022] Furthermore, the sub-elastic shoulder strap is made of spandex.

[0023] The beneficial effects of this utility model are:

[0024] (1) By arranging the sub-elastic shoulder strap and the mother elastic shoulder strap side by side, and by allowing the sub-elastic shoulder strap to slide and adjust its length inside the mother elastic shoulder strap, the combined shoulder strap of this invention can be precisely adjusted in tightness according to individual body shape and comfort requirements. This not only improves the comfort of wearing the strap but also ensures a close fit between the combined shoulder strap and the skin of the back, reducing discomfort caused by looseness or tightness.

[0025] (2) When worn, this utility model tightens the sub-elastic back strap laterally to pull the main elastic back strap, and the main elastic back strap then pulls the upper part of the two cups laterally to make the combined back strap widely applicable to any clothing with a bra.

[0026] (3) Because the elasticity of the sub-elastic shoulder strap is greater than that of the main elastic shoulder strap, when the main elastic shoulder strap is stretched, the sub-elastic shoulder strap can provide additional support to help maintain the stability of the main elastic shoulder strap. At the same time, the sub-elastic shoulder strap is always covered by the main elastic shoulder strap and will not exceed its coverage area, ensuring the aesthetics of the combined shoulder strap. This concealed design allows the combined shoulder strap to maintain functionality while also taking into account aesthetics. Attached Figure Description

[0036] Example 1

[0037] like Figure 1-4 As shown, this embodiment provides an elastic adjustable combination back strap suitable for bra-wearing garments, including a female elastic back strap 2, which is used to connect two symmetrically arranged bra cups 1. The female elastic back strap 2 is located on the back of the bra-wearing garment, and the inner side of the female elastic back strap 2 is used to contact the skin on the back.

[0038] The inner side of the main elastic shoulder strap 2 is provided with a sub-elastic shoulder strap 3 for adjusting its tightness, and the sub-elastic shoulder strap 3 and the main elastic shoulder strap 2 are arranged side by side, inside and outside; the first and last ends of the sub-elastic shoulder strap 3 are respectively connected to the inner side of the main elastic shoulder strap 2.

[0039] The width of the sub-elastic shoulder strap 3 is smaller than the width of the mother elastic shoulder strap 2;

[0040] It should be noted that when worn, because the sub-elastic back strap 3 and the mother elastic back strap 2 are arranged side by side inside and outside, and the width of the sub-elastic back strap 3 is smaller, the sub-elastic back strap 3 is always covered by the mother elastic back strap 2 and will not exceed the coverage area of ​​the mother elastic back strap 2.

[0041] The sub-elastic shoulder strap 3 is slidably connected to a length adjustment buckle 31, and the tightness of the mother elastic shoulder strap 2 can be adjusted by lengthening or shortening the length of the sub-elastic shoulder strap 3.

[0042] The elasticity of the sub-elastic shoulder strap 3 is greater than that of the mother elastic shoulder strap 2.

[0043] Firstly, through the side-by-side arrangement of the sub-elastic shoulder strap 3 and the mother elastic shoulder strap 2, and the sliding connection and length adjustment function of the sub-elastic shoulder strap 3 inside the mother elastic shoulder strap 2, the combined shoulder strap described in this embodiment can be precisely adjusted for tightness according to individual body shape and comfort needs. This not only improves the comfort of wearing it, but also ensures a close fit between the combined shoulder strap and the back skin, reducing discomfort caused by looseness or tightness. At the same time, the length adjustment buckle 31 is a flat buckle, which helps to reduce friction with the skin, reduce the feeling of foreign objects, and improve aesthetics.

[0044] Furthermore, when worn, this embodiment tightens the female elastic back strap 2 laterally by tightening the sub-elastic back strap 3, and the female elastic back strap 2 then tightens the upper part of the two cups 1 laterally, making the combined back strap widely applicable to any bra-integrated garment.

[0045] Furthermore, because the elastic sub-strappable strap 3 is more elastic than the elastic female strap 2, it provides additional support when the female strap 2 is stretched, helping to maintain its stability. This design is particularly important during activity, effectively preventing the straps from slipping or deforming and improving the overall wearing experience. Simultaneously, the sub-strappable strap 3 is always covered by the female strap 2 and never exceeds its coverage area, ensuring the aesthetic appeal of the combined strap design. This discreet design allows the combined straps to maintain both functionality and aesthetics.

[0046] Specifically, the female elastic shoulder strap 2 is a double-layer structure without a back buckle;

[0047] It should be noted that when the bra-like garment is a strapless front-fastening bra, the combined back strap, as part of the bra, utilizes its elastic adjustment function. The sub-elastic back strap 3 first horizontally tightens the main elastic back strap 2, and the main elastic back strap 2 then further horizontally tightens the two cups 1, effectively preventing the bra from slipping down during wear. Moreover, through the synergistic cooperation between the front clasp and the combined back strap, the strapless front-fastening bra can maintain comfort and freedom of movement while achieving a supportive, lift-up, and anti-slip effect, even without shoulder straps.

[0048] Specifically, the mother elastic shoulder strap 2 includes an inner and outer skin-fitting layer 22 and a surface fabric layer 21, and the child elastic shoulder strap 3 is disposed on the skin-fitting layer 22; one side of the skin-fitting layer 22 is a skin-fitting and non-slip surface.

[0049] Specifically, the skin-adhesive layer 22 includes two positioning parts 4, each of which contains a positioning cartilage 41; when worn, each of the positioning parts 4 is in close contact with the underarm skin; the first and last ends of the sub-elastic back strap 3 extend to the positioning parts 4 on both sides respectively;

[0050] More specifically, the first and last ends of the sub-elastic shoulder strap 3 are fixedly connected to the positioning part 4 by means of adhesive or sewing;

[0051] In this embodiment, the positioning part 4 plays a crucial role in fixing and preventing slippage in the design of the elastic shoulder strap 2. The positioning part 4 has a built-in positioning cartilage 41, a design that allows it to fit snugly against the underarm skin during wear, forming a stable support point. Because the positioning cartilage 41 has a certain degree of rigidity and support, it effectively prevents the elastic shoulder strap 2 from slipping or shifting during dynamic activities, thus ensuring that the elastic shoulder strap 2 always remains in the correct position, providing continuous comfort and support.

[0052] Specifically, the fabric layer 21 and the skin-adhesive layer 22 are attached to each other along their upper and lower edges, forming an upper portion and a lower portion respectively; the fabric layer 21 and the skin-adhesive layer 22 form a non-attached cavity between the upper portion and the lower portion;

[0053] The cavity design helps reduce the use of adhesive and makes it more breathable, thus allowing the elastic female shoulder strap 2 to maintain its original elasticity.

[0054] Specifically, the sub-elastic shoulder strap 3 is an elastic structure with inner and outer double layers bonded together;

[0055] In this embodiment, the elastic design of the sub-elastic back strap 3 and the mother elastic back strap 2 enables each elastic back strap to provide stronger support and stability for the bra-wearing garment, ensuring that the bra-wearing garment remains stable during exercise or daily activities and reducing the risk of slipping or shifting.

[0056] Specifically, both the sub-elastic shoulder strap 3 and the mother elastic shoulder strap 2 are made of non-slip fabric, making each elastic shoulder strap skin-friendly and non-slip, further preventing the sub-elastic shoulder strap 3 and the mother elastic shoulder strap 2 from slipping down, while also being lighter and thinner.

[0057] More specifically, the sub-elastic shoulder strap 3 is made of spandex, giving it better elasticity and resilience. Even after repeated stretching, it quickly returns to its original shape, preventing deformation or loosening due to prolonged use and extending the product's lifespan. Furthermore, spandex is lightweight and soft, reducing friction and pressure on the back skin and improving wearing comfort, making it especially suitable for extended wear.

[0058] Example 2

[0059] This embodiment provides another elastic adjustable combination strap suitable for bra-inspired garments. Features not explained in this embodiment can be explained using the methods described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0060] like Figure 5 As shown, the first and last ends of the sub-elastic shoulder strap 3 are movably connected to the positioning part 4 via detachable connecting buckles;

[0061] More specifically, each of the positioning parts 4 is provided with a strap connection point, and the two strap connection points are located on the same horizontal line. This helps to maintain the horizontal position of the sub-elastic strap 3, prevent it from shifting or twisting during use, and further enhance the stability of the sub-elastic strap 3.

[0062] The first and last ends of the sub-elastic shoulder strap 3 are respectively connected to buckles 32, which are used to engage with the shoulder strap connection point;

[0063] In this embodiment, the detachable buckle design makes the installation and removal of the sub-elastic shoulder strap 3 exceptionally simple and quick. Users can easily install and remove the strap without complicated operations or tools, saving time and effort, improving ease of use, and also facilitating the maintenance and replacement of the sub-elastic shoulder strap 3.

[0064] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
