Description

Technical Field

[0001] The utility model relates to the field of underwear accessories, in particular to an underwear shoulder strap adjustment ring and an adjustable shoulder strap. Background Art

[0002] As a kind of clothing, bra has become one of the important clothing that modern people cannot do without. With the continuous improvement of people's living standards, people not only pursue the practicality and functionality of bras, but also pay more attention to the beauty and comfort of bras. Among them, whether the bra fits well is an important factor in whether it can be worn comfortably. The current size parameters of bras generally correspond to the wearer's lower chest size and the difference between the upper and lower chest sizes, which can roughly reflect whether the cup size and strap length of the bra can match the wearer's chest size and chest size. Since the bra also plays a role in lifting and supporting the wearer's chest, it is also very important whether the cup can provide good upward support for the chest. Therefore, it is also crucial for the wearer to have a bra with a suitable length of shoulder straps for the wearer's wearing comfort. However, due to the differences in body shape and height of each wearer, even if the wearer's bra size is the same, the appropriate shoulder strap length is different, so most of the existing bras use adjustable length shoulder straps.

[0003] Specifically, refer to Figure 1A As shown, an existing 8-shaped shoulder strap adjustment ring 10P is schematically shown, wherein the 8-shaped shoulder strap adjustment ring 10P includes a frame 11P and a partition column 12P disposed transversely to the frame 11P, wherein the partition column 12P divides the area defined by the frame 11P into a first through hole 13P and a second through hole 14P, Figure 1B During the installation process, firstly, a fixed end 21P of a shoulder strap 20P is passed through the frame 11P from the first through hole 13P, and then the fixed end 21P is reversed and passed through the frame 11P again from the second through hole 14P, and then the fixed end 21P is sutured and fixed to the shoulder strap 20P using a suture 23P, so that the 8-shaped shoulder strap adjustment ring 10P is set on the shoulder strap 20P. After the 8-shaped shoulder strap adjustment ring 10P is installed on the shoulder strap 20P, further refer to Figure 1C, pass a connecting end 22P of the shoulder strap 20P through a fixing ring 30P provided on the cup, and pass the connecting end 22P through the frame 11P from the second through hole 14P, then reverse the connecting end 22P and pass the connecting end 22P through the frame 11P again from the first through hole 13P, wherein the connecting end 22P is then connected to the bra strap, so that the length of the shoulder strap 20P can be adjusted by adjusting the distance between the 8-shaped shoulder strap adjustment ring 10P and the connecting end 22P along the shoulder strap 20P, so that the wearer can adjust the appropriate shoulder strap length according to his or her own body and wearing habits.

[0004] However, the 8-shaped shoulder strap adjustment ring 10P causes the shoulder strap 20P to pass through the frame 11P multiple times during the production process, resulting in numerous and complicated processes, low production efficiency and high labor costs. In addition, the shoulder strap 20P is also double-stacked on the partition column 12P, causing the corresponding bra to often stand out from the wearer's outer clothes at the position of the 8-shaped shoulder strap adjustment ring 10P, which is not beautiful and easily causes the wearer to feel embarrassed. In addition, since the shoulder strap 20P passes through the first through hole 13P and the second through hole 14P twice, it occupies the space of the first through hole 13P and the second through hole 14P, and the wearer needs to spend a lot of effort to move the shoulder strap 20P in the first through hole 13P and the second through hole 14P when adjusting the shoulder strap 20P. In addition, the fixed end 21P sewn on the strap 20P will also produce a step-type thickness difference, affecting the wearer's wearing comfort. Utility Model Content

Based on the fact that a part of the overlapping segment 23 passes through the frame 11 through the second through-hole 14 to be converted into the transition segment 24, and then a part of the transition segment 24 passes through the frame 11 through the first through-hole 13 to be converted into the length segment 25, the overall length of the belt 20 is extended. And the belt 20 only passes through the first through-hole 13 and the second through-hole 14 once, so there is only one layer of the belt 20 in the first through-hole 13 and the second through-hole 14, so the belt 20 will not occupy the space of the first through-hole 13 and the second through-hole 14, so that the wearer can ensure smooth adjustment of the belt 20.

[0083] It is worth mentioning that the reference Figure 6, the connecting end 22 of the belt body 20 passes through a connecting ring 40 before passing through the second insertion hole 14, wherein the connecting ring 40 can be fixed to one of the cup and the strap of the corresponding underwear, wherein the connecting end 22 of the belt body 20 is connected to the other of the cup and the strap of the underwear to connect the adjustable shoulder strap to the underwear. In some embodiments, the connecting ring 40 may not be pre-set on the belt body 20, and in the subsequent underwear manufacturing process, a ring with an opening is set on the underwear, and the overlapping section 23 of the belt body 20 is inserted into the opening to be connected to the underwear.

[0084] In particular, the adjustable shoulder strap has only a single layer of the strap body 20 on the front side 112 and at most two layers of the strap body 20 on the back side 111, and the strap body 20 has at most two overlapping layers, so the adjustable shoulder strap does not need to overlap multiple layers at the adjustment position, which is beneficial to reduce the thickness and achieve a seamless effect.

[0085] Further references Fig.11 , a bra including the adjustable shoulder straps is shown, wherein the bra also includes a cup portion 50 and two shoulder straps 60 extending from both sides of the cup portion 50, wherein the bra includes two adjustable shoulder straps, wherein the connecting ring 40 is provided on the cup portion 50, and the connecting end 22 is connected to the shoulder strap 60, so that the bra provides a suitable wearing size for the wearer based on the length adjustment of the adjustable shoulder straps. In some embodiments, wherein the connecting end 22 is connected to the cup portion 50, and the connecting ring 40 is provided on the shoulder strap 60, the utility model is not limited to this.

[0086] To further understand the present invention, the present invention also provides a method for manufacturing an adjustable shoulder strap, refer to Figures 5 to 7 The method for manufacturing the adjustable shoulder strap comprises the steps of:

[0087] A. One end 21 of a belt body 20 is sewed and fixed to a fixing post 12 of a bra shoulder strap adjustment ring 10 at the rear side 111 of the bra shoulder strap adjustment ring 10 by means of a suture 30;

[0088] B. After folding the belt body 20, pass the other end 22 of the belt body 20 from the rear side 111 through a frame 11 at one side 14 of the fixing column 12 to the front side 112 of the bra shoulder strap adjustment ring 10;

[0089] C. After folding the belt body 20 , the other end 22 of the belt body 20 passes through the frame body 11 from the front side 112 to the rear side 111 at the other side 13 of the fixing column 12 .

[0090] It is worth mentioning that the manufacturing method of the adjustable shoulder strap also includes a step of stamping the underwear shoulder strap adjustment ring 10 before step A, wherein the underwear shoulder strap adjustment ring 10 includes the frame 11 and the fixed column 12, wherein the frame 11 defines a penetration space 110, wherein the fixed column 12 is horizontally arranged on the frame 11 and the penetration space 110 is divided into a first penetration hole 13 and a second penetration hole 14 on both sides of the fixed column 12, wherein the fixed column 12 has at least one threading hole 15 which is consistent with the opening direction of the first penetration hole 13 and the second penetration hole 14.

[0091] In particular, during the manufacturing process, the belt body 20 only needs to pass through the first through hole 13 and the second through hole 14 once, thereby simplifying the process steps of the manufacturing method of the adjustable shoulder strap and improving production efficiency.

[0092] It is worth mentioning that in the step B, before the other end 22 of the belt body 20 passes through the frame body 11 , a step of passing the other end 22 of the belt body 20 through a connecting ring 40 is also included.
