Bra structure

Abstract

A bra structure includes: two cups; a platform disposed at the lower edge of the two cups; two back straps respectively disposed on the outer side of the two cups and connected to the platform; a back buckle and a back hook respectively disposed on the outer edge of the two back straps and interlocked with each other; and two shoulder straps connecting the two cups and the two back straps; characterized in that: the back straps are made of a folded elastic fabric, having an overlapping front back piece and a back back piece, the lower edge of the front back piece and the back back piece forming a folded edge, and the inner surface of the front back piece and the inner surface of the back back piece are not connected or fixed, so that the upper edge of the front back piece and the back back piece are non-connected; thereby, the two back straps, through the double-layer design of a single elastic fabric fold, not only maintain high extensibility, softness and seamlessness, but also ensure a stable fit between the back straps and the skin.

Claims

1. A bra structure comprising: two cups; a platform disposed at the lower edge of the two cups; two back straps respectively disposed on the outer side of the two cups and connected to the platform; a back buckle and a back hook respectively disposed on the outer end edge of the two back straps and interlocking with each other; and two shoulder straps connecting the two cups and the two back straps; characterized in that: the back straps are made of an elastic fabric folded together, having a front back piece and a back back piece overlapping each other, the lower end edge of the front back piece and the back back piece forming a folded edge, and the inner surface of the front back piece and the inner surface of the back back piece are not connected or fixed, so that the upper end edge of the front back piece and the back back piece are in a non-connected state.

2. The bra structure as described in claim 1, wherein, The second is that the carrying strap and the platform are made of the same elastic fabric. The lower edge of the platform is also folded to form a folded edge, and an elastic webbing is sewn into the inside of the fold of the platform.

3. The bra structure as described in claim 1, wherein, The upper edges of the front back panel and the back back panel are aligned and overlap each other, and a back point is provided at the end of the two back straps away from the two cups. Each of the two cups is provided with a cup shoulder handle, and the two ends of the two shoulder straps are respectively connected to the cup shoulder handles of the two cups and the back point of the two back straps.

4. The bra structure as described in claim 1, wherein, Secondly, the carrying strap and the platform are not made of the same elastic fabric. The platform has an elastic webbing on the inside and two interlocking connecting pieces on the outside.

5. The bra structure as described in claim 1, wherein, The upper edge of the front back panel of the bra strap extends beyond the upper edge of the rear back panel to form a raised support portion. One end of the raised support portion includes a raised side edge disposed on the outer edge of a side edge of the bra cup, and a front shoulder strap disposed on the upper outer edge of the bra cup and extending upward and outward. A front back point is provided at the end of the raised support portion away from the bra cup.

6. The bra structure as described in claim 5, wherein, The two ends of the shoulder straps are respectively connected to the two cups and the front back of the two back straps. The front shoulder handles of the two back straps are respectively overlapped on the front of the two shoulder straps, and the ends of the front shoulder handles are fixed to the shoulder straps.

7. The bra structure as described in claim 1, wherein, The inner lining surface of the cup has a three-dimensional texture, which includes at least two inner corrugations and at least two outer corrugations. The two inner corrugations form a recessed inner corrugation groove, and the two outer corrugations form a recessed outer corrugation groove. One end of the inner corrugation is adjacent to one end of the outer corrugation and forms a V-shaped corrugation. At the same time, a recessed V-shaped corrugation groove is formed below the V-shaped corrugation.

8. The bra structure as described in claim 7, wherein, The three-dimensional texture extends along the lower arc edge of each cup. The inner wavy area is smaller than the outer wavy area, and the V-shaped wavy area is not centered on the inner lining surface of the cup. The outer wavy area extends further to one side of the cup from the end away from the inner wavy area. Furthermore, the upper end of the outer wavy area is provided with a plurality of extended wavy lines.
