Description

Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to a strapless bra. Background Technology

[0002] Strapless bras, as an important category of modern women's underwear, are widely popular because they can be paired with various fashionable outfits such as off-the-shoulder and low-cut styles. However, existing strapless bras have the following technical drawbacks: Traditional strapless bras typically use a one-piece center gore structure to fix the left and right cups together, making it impossible to adjust the cup angle. This makes it difficult to accommodate different breast shapes, such as wide-set, symmetrical, or asymmetrical, resulting in poor fit and support. Existing adjustment mechanisms mostly only adjust the tightness of the bra and cannot precisely adjust the cup angle, failing to meet the needs of different occasions, such as the need for comfort and naturalness for everyday wear, while formal wear requires a stronger push-up effect.

[0003] To address the aforementioned issues, this invention proposes a novel strapless bra that achieves adjustable cup angles, strong adaptability, and comfortable wear through a combination of structural innovation and material optimization.

[0004] Therefore, the existing technology of underwear technology needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a strapless bra to solve problems such as fixed cup angle and poor fit.

[0006] To achieve the above objectives, the present invention adopts the following solution: A strapless bra includes a left cup and a right cup, with a separate center gore structure between the left cup and the right cup. The two ends of the separate center gore structure are respectively provided with hinge structures for hinged to the left cup and the right cup, and a tightening structure is provided between the left cup and the right cup.

[0007] Furthermore, the hinge structure includes hinge portions respectively disposed on the inner sides of the left and right cups, and each end of the split heart-shaped structure is provided with a hinge seat, and the hinge portion and the corresponding hinge seat are hinged together.

[0008] Furthermore, the tightening structure includes buckles disposed inside the left and right cups, with a strap passing through and connecting the two buckles, and a fixing structure disposed between the two ends of the strap.

[0009] Furthermore, the fixing structure includes a first Velcro strap at one end of the strap and a second Velcro strap at the other end.

[0010] Furthermore, the left and right cups are made of gradient density memory foam composite material, consisting of a skin-friendly memory foam layer, a supporting memory foam layer, and a shaping memory foam layer from the inside to the outside. The layers are bonded together seamlessly with a nano-scale hot melt adhesive film.

[0011] Furthermore, the strap is woven from graphene-modified polyamide elastic fibers.

[0012] In summary, the advantages of this utility model over the prior art are: This invention addresses the shortcomings of existing lingerie technology. Through its structural design, it offers the following advantages: The combination of a separate center gore structure and a hinged structure allows for flexible adjustment of the cup angles at multiple angles, precisely adapting to different breast shapes such as outward spread, symmetrical, and asymmetrical. It also meets the needs of various scenarios, including comfortable everyday wear and formal dress support, solving the problem of fixed cup angles in traditional strapless bras. The tightening structure, secured with Velcro, is simple and easy to use, quickly locking the desired cup angle and preventing loosening during wear, thus balancing adjustment efficiency and wearing stability.

[0014] 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.

[0015] Please see Figures 1-3 This utility model provides A strapless bra includes a left cup 1 and a right cup 2. A separate center gore structure 3 is provided between the left cup 1 and the right cup 2. The two ends of the separate center gore structure 3 are respectively provided with hinge structures 4 for hinged to the left cup 1 and the right cup 2. A tightening structure 5 is provided between the left cup 1 and the right cup 2. The tilt angle of the two left cups 1 and the right cup 2 around the hinge structure 4 can be adjusted by tightening or loosening the tightening structure 5.

[0016] The hinge structure 4 at both ends of the split heart-shaped structure 3 provides the basic conditions for the left cup 1 and the right cup 2 to rotate around the hinge point; then, through the tightening structure 5 between the left cup 1 and the right cup 2, the force state of the two cups is changed by the "tightening / relaxing" action, thereby adjusting their tilt angle around the hinge structure 4 to adapt to different breast shapes and wearing needs.

[0017] Hinged connection: The hinged parts 401 on the inner side of the left cup 1 and the right cup 2 are hinged to the hinged seats 402 at both ends of the split heart-shaped structure 3, forming a rotatable connection similar to a "hing", providing mechanical support for cup tilt angle adjustment and ensuring smooth rotation.

[0018] Tightening control: The buckles 501 on the inner sides of the left cup 1 and the right cup 2 provide a fixed fulcrum for the straps 502. After the straps 502 pass through the two buckles 501, tightening the straps 502 will cause the two cups to move closer to the middle, reduce the tilt angle and enhance the gathering. Loosening the straps 502 will allow the cups to naturally unfold, increase the tilt angle and improve comfort. The first Velcro 503 at one end of the straps 502 and the second Velcro 504 at the other end are attached to fix the tightness of the straps 502 and lock the adjusted cup tilt angle.

[0019] The hinge structure 4 of this utility model includes hinge parts 401 respectively disposed on the inner sides of the left cup 1 and the right cup 2, and each end of the split heart-shaped structure 3 is provided with a hinge seat 402, and the hinge parts 401 and the corresponding hinge seat 402 are hinged together.

[0020] The tightening structure 5 of this utility model includes a buckle 501 disposed inside the left cup 1 and the right cup 2, a strap 502 passing through and connecting the two buckles 501, and a fixing structure 5030 disposed between the two ends of the strap 502.

[0021] The fixing structure 5030 of this utility model includes a first Velcro 503 disposed at one end of the strap 502 and a second Velcro 504 disposed at the other end.

[0022] The left cup 1 and right cup 2 of this invention are made of gradient density memory foam composite material. From the inside to the outside, they are skin-friendly memory foam layer 100, support memory foam layer 200 and shaping memory foam layer 300. The layers are bonded together seamlessly with nano-level hot melt adhesive film. The gradient density memory foam composite material has temperature response characteristics in the range of 32-37℃, and can dynamically adjust its softness and hardness according to changes in body temperature to adapt to the support needs under different activity states.

[0023] The strap 502 of this invention is woven from graphene-modified polyamide elastic fiber with a fiber diameter of 50-80 μm and a weaving density of 280-320 stitches / inch. The graphene content in the graphene-modified polyamide elastic fiber is 0.8-1.2%, which allows the strap 502 to maintain an elastic recovery rate of 300-400%, an active temperature control range of 20-30℃, and a durable antibacterial performance with an antibacterial rate of ≥99% after ≥1500 washes.

[0024] The gradient density memory foam composite material of the left cup 1 and right cup 2 contains a skin-friendly memory foam layer 100, a support memory foam layer 200, and a shaping memory foam layer 300. It dynamically adjusts its softness and firmness according to the body temperature, and better conforms to the chest after the tilt angle is adjusted. The graphene modified polyamide elastic fiber of the strap 502 has a high elastic recovery rate, ensuring that the strap 502 is not easily deformed during tightening / loosening operations, and has long-lasting antibacterial and temperature control properties, ensuring ease of operation and wearing experience.
