Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing technology, and in particular to an underwear with dynamic support effect. Background Technology
[0002] With economic development, the clothing industry has also developed rapidly. People's demand for clothing is increasing and their requirements are getting higher. Among them, underwear is a very important close-fitting garment in the daily lives of most people.
[0003] Currently, most women's bras consist of shoulder straps, back straps, cups, underwire (or plastic wire), and foam padding. The foam padding inside the cups makes the breasts appear fuller, while the underwire (or plastic wire) prevents sagging and lifts the breasts. However, the underwire can compress the breasts. While ordinary sports bras don't have the compression of underwires, their support is often poor, making it difficult to provide adequate support for the breasts during exercise. Furthermore, different sports require different levels of breast support, and ordinary bras struggle to meet these higher demands, thus necessitating improvement. Utility Model Content
[0004] This invention provides a support strip with different hardness options that can be selected according to different sports environments, and can achieve good dynamic support during exercise, increasing comfort during exercise. It is easy to install and replace, and does not cause a foreign body sensation when worn or used during exercise. It solves the technical problems of existing bras, which usually have underwires, which, although they have a certain support effect, can easily compress the breasts and cause damage. Ordinary sports bras are comfortable but have poor support, making it difficult to meet the different support effects of different sports and failing to meet the higher practical needs of users.
[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a bra with dynamic support effect, comprising a bra body, the bra body including two cups on the front side, a bandeau attached to the lower side of the cups, and a back piece on the back side of the cups, which is connected to the cups via shoulder straps. The cups, shoulder straps, and back piece of the bra body are cut from a single piece. A detachable support strip is embedded in the cup, which can be replaced with support strips of different hardness. The support strip is fixed to the bandeau via positioning components. In use, the support strip can be replaced with a different hardness according to different usage environments, such as a soft support strip for yoga and a hard support strip for running. The support strip can be directly inserted into the bra inside the cups. The function of the support strip is to provide support during exercise. The support strip can be freely selected and replaced according to different exercise environments, and it is fixed to the bandeau via positioning components and is not easily moved.
[0006] Preferably, the support strip is made of nickel-titanium shape memory alloy or thermoplastic polyurethane. Nickel-titanium shape memory alloy is a metal alloy composed of nickel (Ni) and titanium (Ti) with a near-equal atomic ratio. It has a unique shape memory effect and superelastic properties. Nickel-titanium alloy can recover a pre-set shape at a specific temperature. During exercise, as body temperature rises, the shape memory alloy is triggered to deform, generating a reverse support force, thereby achieving a dynamic support effect. Thermoplastic polyurethane has excellent high elasticity and can generate a reverse support force as muscles stretch during exercise. Both materials can achieve good dynamic support effects and can be selected according to needs. This utility model uses nickel-titanium shape memory alloy as an example for explanation.
[0007] Preferably, the support strip is a thin sheet or a cylindrical structure. The support strip can be a thin sheet or a cylindrical structure. This invention takes a cylindrical support strip as an example for explanation. The cross-section of the support strip is cylindrical, and the diameter of the support strip is between 1.0-1.5 mm.
[0008] Preferably, the support strip is an "I"-shaped or "U"-shaped structure. The support strip can be a vertical "I"-shaped structure or a U-shaped structure. This utility model uses a U-shaped support strip as an example for explanation.
[0009] Preferably, the support strip has a certain curvature in its longitudinal direction. The support strip in this invention has a certain curvature when viewed longitudinally, designed to fit the chest structure and avoid creating a foreign body sensation.
[0010] Preferably, the inner side of the bra cup has several U-shaped replacement slots. Two U-shaped replacement slots are located at the top inner side of the bra cup, and the support strip is inserted into these slots from above. The replacement slots have an inverted U-shaped structure.
[0011] Preferably, the positioning element includes a magnetic sheet embedded in the lower enclosure, and both ends of the support strip are provided with magnetic snap-fits that cooperate with the magnetic sheet. During installation, simply insert the support strip into the replacement slot from above; the two ends of the support strip will be attracted and fixed with the magnetic sheet. When replacing, simply pull out the support strip. Replacement and installation are very convenient, and the resulting support effect is excellent.
[0012] Therefore, the underwear with dynamic support effect of this utility model has the following advantages: it can select support strips with different hardness according to different sports environments, and can achieve good dynamic support during exercise, increasing comfort during exercise, and is easy to install and replace, and will not produce a foreign body sensation when worn and exercised.

[0016] In the picture, the main body of the bra is 1, the cup is 2, the underband is 3, the support bar is 4, the magnetic buckle is 5, and the replacement slot is 6. Detailed Implementation
[0017] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] Example:
[0019] like Figure 1 and 2 As shown in Figure 3, a bra with dynamic support effect includes a bra body 1. The bra body 1 includes two cups 2 on the front side, a band 3 connected below the cups 2, and a back piece connected to the back side of the cups 2. The back piece and the cups 2 are connected by shoulder straps. The cups 2, shoulder straps and back piece of the bra body 1 are cut and formed from a single piece.
[0020] A detachable support strip 4 is embedded on the inner side of the cup 2. The support strip 4 can be replaced with a support strip of different hardness according to different needs. The support strip 4 is fixed to the lower part 3 by a positioning component.
[0021] The support bar 4 is made of nickel-titanium shape memory alloy, and the cross-section of the support bar 4 is cylindrical, with a diameter between 1.0-1.5mm.
[0022] The support bar 4 has a U-shaped structure and a certain curvature in its longitudinal direction; several U-shaped replacement slots 6 are provided on the inner side of the cup 2, and the support bar 4 is inserted downward into the replacement slots 6.
[0023] The positioning component includes a magnetic sheet embedded in the lower enclosure 3, and magnetic snap-fits 5 that cooperate with the magnetic sheet are installed at both ends of the support strip 4.
[0024] When using it, the support bar 4 can be replaced with a different hardness according to different usage environments, such as a soft support bar 4 for yoga and a hard support bar 4 for running.
[0025] During installation, simply insert the support bar 4 into the replacement slot 6 from above. The two ends of the support bar 4 are attracted and fixed to the magnetic sheet. When replacing, simply pull out the support bar 4.
[0026] During exercise, as body temperature rises, the shape memory alloy deforms, generating a reverse support force, thus achieving a dynamic support effect. Replacement and installation are very convenient, and the support effect is good. It can be freely replaced according to different sports environments without causing a foreign body sensation.
[0027] The specific embodiments described herein are merely illustrative of the concept of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
