Description

Technical Field

[0001] This utility model belongs to the field of underwear accessories technology, specifically relating to an underwear fastener that enhances privacy. Background Technology

[0002] In modern lingerie design, front-closure bras are favored by many consumers because they are easy to wear and suitable for various body types. In practical applications, unlocking a front-closure bra usually requires the user to hold the left and right sides of the fastener and pull it inwards until the fastener bends from the horizontal direction (180°) to an angle of less than 90°, thus unlocking the fastener. After unlocking, the user still needs to separate the two cups separately to completely unfasten the bra.

[0003] However, the fasteners of traditional front-closure bras are quite conspicuous, usually located in a prominent position on the front of the bra. In daily activities or social situations, the fasteners may be accidentally caught on clothing, backpacks, or other items, causing them to unlock unintentionally. Furthermore, due to the rapid transmission of information online, most people are already aware of the common way to unlock front-closure bras, making them easy targets for malicious individuals who may deliberately unfasten the fasteners to cause embarrassment and inconvenience to users, and may even threaten their privacy and safety.

[0004] Secondly, the traditional method requires users to precisely hold the left and right sides of the fastener and simultaneously pry it inwards. This design is particularly inconvenient for users with poor hand dexterity or those who need to quickly unfasten their bras in an emergency. Utility Model Content

[0005] The purpose of this invention is to provide a bra fastener that enhances privacy, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a privacy-enhancing underwear fastener, comprising a first mounting section and a second mounting section, characterized in that a positioning buckle seat is provided on the right side of the first mounting section, the top of the positioning buckle seat has a slot, and the right side of the positioning buckle seat has a slot through a backing plate; a locking protrusion is connected to the left side of the second mounting section through a locking plate, the locking protrusion has a through groove, and an installation hole is provided on the locking protrusion at a position in front of the through groove; an elastic plate is provided in the installation hole, and a buckle head is provided on the elastic plate.

[0007] Preferably, the positioning buckle seat has a fastening groove on its front side.

[0008] Preferably, the locking protrusion and the slot are the same size.

[0009] Preferably, the card plate and the card slot have the same length and thickness.

[0010] Preferably, the elastic plate and the buckle head are made of rigid plastic.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The buckle unlocking position of this utility model is designed on the side closer to the user, which is relatively hidden. This greatly reduces the possibility that it can be easily discovered and deliberately unlocked by others, effectively protecting the user's privacy and avoiding the embarrassment and inconvenience caused by the buckle being accidentally unlocked.

[0013] This invention unlocks by pressing the buckle head. This unique unlocking method differs from the conventional method of unlocking front-fastening bras, increasing the difficulty of unlocking and effectively preventing others from deliberately unfastening the fasteners, thereby better protecting the user's privacy and security.

[0014] The fasteners in this invention do not require frequent bending operations, and unlocking only requires a simple pressing of the buckle head, simplifying the unlocking process and improving the convenience and comfort of users. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figures 1 to 6 The illustrated underwear fastener for enhancing privacy includes a first mounting section 1 and a second mounting section 2. The first mounting section 1 has a positioning fastener 3 on its right side, which is hollow and has a slot 4 at its top. A groove 6 is formed on its right side via a backing plate 5. The groove 6 is smaller in thickness and length than the slot 4. The second mounting section 2 has a locking protrusion 8 connected to its left side via a locking plate 7. The locking protrusion 8 has a through groove 9, and a mounting hole 10 is formed on the locking protrusion 8 in front of the through groove 9. An elastic plate 11 is placed inside the mounting hole 10, and a buckle head 12 is provided on the elastic plate 11. A fastening groove 13 is formed on the front side of the positioning fastener 3. The locking protrusion 8 and the slot 4 are the same size. The locking plate 7 and the groove 6 have the same length and thickness. The elastic plate 11 and the buckle head 12 are made of rigid plastic.

[0025] The fastener unlocking position of this utility model is designed on the side closer to the user, which is relatively concealed and greatly reduces the possibility of it being easily discovered and deliberately unfastened by others, effectively protecting the user's privacy and avoiding the embarrassment and inconvenience caused by the fastener being accidentally unfastened. This utility model unlocks by pressing the buckle head 12. This unique unlocking method is different from the conventional front-fastening bra unlocking method, increasing the difficulty of unlocking and effectively preventing others from deliberately unfastening the fastener, thereby better protecting the user's privacy and security. The fastener in this utility model does not require frequent bending operations, and unlocking only requires a simple pressing of the buckle head 12, simplifying the unlocking process and improving the user's convenience and comfort during use.

[0026] Example 2

[0027] like Figures 1 to 6The illustration shows a privacy-enhancing bra fastener, specifically for a front-fastening bra. The bra has a first mounting section 1 and a second mounting section 2 on the inner sides of each of the two cups. Understandably, when the first mounting section 1 and the second mounting section 2 are connected and fixed together, the two cups, the bust area, and the entire bra can be worn. In practical application, the user holds the first mounting section 1 and the second mounting section 2 inwards and secures them together, thus completing the fastening and wearing of the two cups and the entire bra. The first mounting section 1, the second mounting section 2, and the entire fastener are all made of metal, which has excellent corrosion resistance. During daily wear, components such as sodium chloride in human sweat may corrode some plastic fasteners, causing discoloration, deformation, or even damage. The metal material effectively prevents this corrosion, maintaining the original performance and appearance of the fastener. Furthermore, bras undergo various movements during wear, such as bending and twisting; the metal fastener can withstand significant tensile and compressive forces and will not easily break or be damaged.

[0028] A positioning buckle 3 is provided on the right side of the first installation section 1, specifically on the side near the second installation section 2. The positioning buckle 3 is rectangular in shape and hollow. The second installation section 2 can be fixed to the positioning buckle 3 of the first installation section 1 to fix the two cups. The top of the positioning buckle 3 has a slot 4, and the right side of it has a groove 6 through the abutment 5. The thickness and length of the groove 6 are smaller than those of the slot 4. Therefore, when the positioning buckle 3 is viewed from above, the slot 4 will appear as a right-side "convex" groove.

[0029] Correspondingly, on the left side of the second mounting section 2, specifically on the side closer to the first mounting section 1, there is a retaining plate 7. The bottom of the retaining plate 7 is slightly shorter than the locking protrusion 8. The length and thickness of the retaining plate 7 are consistent with the slot 6. That is, the user can hold the second mounting section 2 and drive the retaining plate 7 into the slot 6. Then, when the locking protrusion 8 is the same size as the slot 4, after the retaining plate 7 is driven into the slot 6, the locking protrusion 8 can also be inserted into the slot 4, thereby achieving left and right limit of the first mounting section 1 and the second mounting section 2.

[0030] The above completes the basic operation of installing the second installation section 2 into the first installation section 1. To further strengthen the fixed connection between the two, a rectangular through groove 9 is also opened on the locking protrusion 8. At the same time, an installation hole 10 is opened on the locking protrusion 8 at the position in front of the through groove 9. An elastic plate 11 is provided in the installation hole 10. Specifically, the elastic plate 11 can swing up and down with the installation hole 10 as the fulcrum. Under normal conditions, the elastic plate 11 is in a higher position and will protrude into the through groove 9. When it is squeezed, it will move downward into the through groove 9 and no longer protrude.

[0031] The end of the elastic plate 11 is provided with a buckle head 12, which means that the elastic plate 11 can drive the buckle head 12 to swing with a large amplitude after being squeezed. Correspondingly, a fastening groove 13 is opened on the front side of the positioning buckle seat 3. The fastening groove 13 is the same size as the buckle head 12. In the normal state, the elastic plate 11 is in a higher position, and the buckle head 12 will protrude upward through the through groove 9 into the fastening groove 13, thereby indirectly realizing the upper and lower limits of the first installation section 1 and the second installation section 2. Thus, when it is necessary to unlock the first installation section 1 and the second installation section 2, press the buckle head 12 downward to move it and drive the elastic plate 11 to swing downward. At this time, the buckle head 12 is no longer located in the fastening groove 13, and the first installation section 1 and the second installation section 2 are only limited to the left and right. Then, the user moves the locking protrusion 8 upward and no longer inserts it into the slot 4. During this period, the user stops pressing the buckle head 12, thereby realizing the complete unlocking of the first installation section 1 and the second installation section 2 and completing the disassembly of the bra cup.

[0032] The buckle head 12 and the elastic plate 11 are made of the same material, either nylon or polyoxymethylene, which are rigid plastics. These plastic materials are elastic within a certain range and can recover their original shape after being squeezed. In repeated use, the rigid plastic can maintain good performance and meet the usage requirements of the elastic plate 11 and the buckle head 12.

[0033] In summary, the traditional method for unfastening front-clasp bras involves holding the left and right sides of the clasp and simultaneously pulling inwards until the clasp bends from a horizontal angle (180°) to an angle of less than 90°. This unlocks the clasp. After unlocking, the user still needs to separate the two cups by moving the clasp from the top and bottom to completely unfasten the bra. This method is relatively complex, and in actual use, the clasp is usually quite conspicuous and easily affected by external factors. For example, it may be accidentally snagged by other objects during daily activities, causing it to unlock unexpectedly; or it may be used by malicious individuals to deliberately unfasten the clasp, causing embarrassment and inconvenience to the user, and even potentially threatening the user's privacy and safety. The fasteners in this invention do not require the complex bending operations of traditional bras. They can be easily unlocked with a simple pressing action, which not only greatly improves the convenience and comfort of users but also reduces the risk of damage to the fasteners due to frequent bending. In addition, the fasteners in this invention are designed with the unlocking position on the side closer to the user, making them more concealed. The unlocking method is also different from that of conventional front-fastening bras, which can effectively prevent malicious people from deliberately unlocking the fasteners, thus improving the user experience and providing a safer, more convenient, and more comfortable bra option.
