Description

[Technical Field]

[0001] The present invention relates to the technical field of bags, and more particularly to a shoulder strap clamping device and a detachable shoulder strap. [Background technology]

[0002] As the quality and appearance of eco-friendly bags continue to improve, more and more consumers are becoming interested in using them, and their application scenarios are becoming more diverse and not limited to shopping in supermarkets. However, most eco-friendly bags currently on the market typically only have handles, which means users can only carry them by hand, leaving both hands free, which is inconvenient. On the other hand, eco-friendly bags are difficult to enhance their fashion sense when carried by hand. Therefore, many eco-friendly bags with shoulder or crossbody functions have emerged. For example, Chinese Patent CN215958739U discloses a PE plastic handbag for clothing packaging with a shoulder strap function, which allows users to freely switch between double-shoulder, single-shoulder, and hand-carrying by adding a strap to the handbag. However, the cost of adding double or single shoulder straps or hand straps to a handbag makes it difficult to popularize this design for other eco-friendly bags.

[0021] In order to clarify the objectives, technical means and advantages of the embodiments of the present invention, the technical means of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention shown in the drawings is not intended to limit the scope of the invention sought to be protected, but merely represents selected embodiments of the present invention. Example

[0022] 1 to 21, this embodiment provides a shoulder strap clamp device that is disposed on both ends of a shoulder strap 1 and includes a clamp body 21 and a fastening member 22, the clamp body 21 having a clamp portion 211 and a first lock portion 212, the clamp portion 211 being used to fit onto or clamp the bag 3, the fastening member 22 having a second lock portion 221 that engages with the first lock portion 212, and the second lock portion 221 is configured to be operably locked or unlocked with the first lock portion 212, thereby fitting tightly to or separating from the bag 3 within the clamp portion 211, and detachably attaching the shoulder strap 1 to the bag 3, allowing the bag 3 to be worn over one or both shoulders.

[0023] The bag 3 may be made of cloth or plastic, and the shoulder strap 1 may be made of cotton, nylon, leather, or other materials, but are not limited thereto. In this embodiment, the fastening member 22 is operated to fasten the second locking member 221 and the first locking member 212, thereby tightly fitting the bag 3 within the clamping member 211, thereby attaching the shoulder strap 1 to the bag 3 and enabling one- or two-shoulder carrying, leaving both hands free. Furthermore, the clamping device 2 and the bag 3 are detachably arranged, allowing the bag to be used repeatedly or attached to different bags 3, reducing usage costs. A user can attach one or two shoulder straps 1 according to their needs. If a user chooses to use a single shoulder strap 1, the clamping members 211 on both ends of the shoulder strap 1 can be fitted along different or opposite sides of the bag 3 and fastened with the fastening member 22, allowing the user to wear the single shoulder strap 1 over one shoulder or across the body. 21, if a user selects two shoulder straps 1, the two shoulder straps 1 can be placed on the same side of the bag 3, and the clamping devices 2 on both ends of the shoulder straps 1 can clamp the upper and lower ends of the bag 3, respectively, to achieve a double-shoulder carry function. Of course, the user can select the attachment position and attachment angle of the clamping devices 2 and the number of shoulder straps 1 according to their own needs, allowing for flexible selection and diversifying usage methods, satisfying the user's pursuit of use in various scenarios and personalization.

[0024] In a preferred embodiment, the clamp body 21 is provided with a hanging loop 213 for connecting to the shoulder strap 1. The hanging loop 213 is a metal loop that can be released when sufficient force is applied, allowing the shoulder strap 1 to be attached or detached from the clamp body 21. Users can change the shoulder strap 1 to one of different materials, colors, or lengths according to their needs, making it compatible with any bag, enhancing the bag's fashionability and increasing its value and usability. Users can also place any rope-like object on the hanging loop 213 to create the effect of a shoulder strap 1, but this is not a limitation.

[0025] Based on the above embodiment, in an alternative embodiment of the present invention, the clamp body 21 is provided with a passage 214 through which the second locking portion 221 enters, and the passage 214 communicates with the clamping portion 211. The clamping portion 211 is provided penetrating along one side of the clamp body 21, and an opening is formed at the end of the clamp body 21 opposite the shoulder strap 1, through which the bag 3 can enter. Preferably, the cross section of the clamp body 21 is U-shaped. In this embodiment, the first locking portion 212 and the second locking portion 221 include the following three embodiments.

[0026] 1 to 7, in the first embodiment, first locking portion 212 facing passage 214 is formed with first teeth, and second locking portion 221 is formed with second teeth, and the first teeth and second teeth are magnetically attracted to each other through a convex-concave fit. Specifically, second locking portion 221 protrudes from the center of fastening member 22, and the first teeth are stepped convex portions, and the second teeth are correspondingly stepped concave portions. Since the size of passage 214 matches the periphery of second locking portion 221, the position of second locking portion 221 is restricted when inserted into passage 214, and second locking portion 221 is aligned with first locking portion 212, realizing a convex-concave fit between the first teeth and second teeth. The other portion of the clamping member 22 is larger than the passage 214 and is located outside the clamping body 21 to facilitate separation of the clamping member 22 and the clamping body 21. The first locking portion 212 and the second locking portion 221 may be formed of magnets, or one may be a magnet and the other may be formed of a magnetically attractable metal material. The first locking portion 212 is configured to be fitted to the clamping body 21. In other embodiments, the first locking portion 212 may be integrally formed with the clamping body 21, but this is not particularly limited. During use, after fitting the clamping member 211 to the bag 3, the user holds the clamping member 22 by hand and inserts the second locking portion 221 along the passage 214 until it is attracted to the first locking portion 212. In this case, the bag 3 inside the clamping member 211 is clamped between the first locking portion 212 and the second locking portion 221. The provision of the teeth increases the clamping force, ensuring that the clamping device 2 does not loosen when the user uses the shoulder strap 1. When disassembling, the fastening member 22 can be simply removed from the first locking portion 212 by hand or with another tool, making the operation simple and easy to attach and detach.

[0027] In the second embodiment, referring to FIGS. 8 to 11, the first locking portion 212 is provided as a threaded hole in the passage 214, and the second locking portion 221 is provided as a threaded rod that fits into the threaded hole. The other end of the fastening member 22, opposite the second locking portion 221, is provided with a driving portion 222. The driving portion 222 is larger than the threaded rod, and a force application groove 2221 is provided along the outer periphery of the driving portion 222. This increases friction when a user applies force, making it easier to rotate the threaded rod. Preferably, a plurality of force application grooves 2221 are arranged circumferentially on the outer wall of the driving portion 222. During use, after the user fits the clamping portion 211 to the bag 3, the user rotates the driving portion 222 to insert the threaded rod into the clamping portion 211 using the threaded hole. The installation is completed when the end face of the threaded rod comes into close contact with the bag 3. Disassembly requires simply rotating the driving portion 222 to separate the threaded rod from the bag 3. In this embodiment, the component configuration is simple, the number of components is small, and manufacturing costs can be reduced. This configuration places relatively few restrictions on the materials used for the clamp body 21 and the fastening member 22, and the clamp body 21 and the fastening member 22 can be made of lightweight materials such as aluminum or plastic, and are not particularly limited.

[0028] 12 to 14, based on the second embodiment, the second locking portion 221 is preferably configured to be connected to the bolt 225 via a connecting member 226, the second locking portion 221 is provided with a plurality of first convex teeth, a receiving groove 224 for receiving the seam of the bag is formed along the center of the second locking portion 221, and a plurality of second convex teeth for increasing the clamping force are provided on the side wall of the clamp body 21 facing the second locking portion 221. When the seam of the bag is clamped using the clamp device 2, the seam can be received in the receiving groove 224, and the second locking portion 221 is moved by rotating the bolt 225, and the first convex teeth and the second convex teeth cooperate to clamp the bag 3 accordingly. This reduces the limitations imposed by the clamping position of the clamp device 2, making it more versatile. Note that connecting member 226 matches with the mounting hole of second locking portion 221 and is connected coaxially with bolt 225, so that the circular motion of bolt 225 is converted into linear motion of second locking portion 221. The method of connecting bolt 225 and connecting member is not particularly limited and may be a screw connection or a rivet connection.

[0029] 15 to 20, in embodiment 3, the first locking portion 212 is provided with a plurality of inclined teeth that protrude outward along the passage 214, and the second locking portion 221 is configured to slide into the side surface of the clamp body 21 to engage with the inclined teeth. Preferably, the passage 214 has a wide position 2142 and a narrow position 2141, and the fastening member 22 is provided with a guide groove 223, so that when the fastening member 22 moves from the wide position 2142 to the narrow position 2141, the clamp body 21 at the narrow position 2141 engages with the guide groove 223 to restrict the position of the fastening member 22. Furthermore, the vertical size of the fastening member 22 matches the wide position 2142, and the guide grooves 223 are provided along both the upper and lower ends of the fastening member 22. When the fastening member 22 moves to the narrow position 2141, both the upper and lower ends of the fastening member 22 are restricted by the clamp body 21, preventing it from slipping out from the front of the clamp body 21. Furthermore, due to the engagement of the inclined teeth, the fastening member 22 will not fall off the side of the clamp body 21 unless an external force is applied. During use, after the clamp portion 211 is fitted to the bag 3, the fastening member 22 is inserted along the wide position 2142 of the passage 214 and moved from the wide position 2142 to the narrow position 2141 to engage with the inclined teeth of the first locking portion 212, thereby clamping the bag 3. During disassembly, it is only necessary to apply force to the fastening member 22 to move it from the narrow position 2141 to the wide position 2142. In this embodiment, the bag 3 can be switched between a clamped and an unclamped state by moving the fastening member 22, allowing for quick attachment and detachment. Preferably, a non-slip surface is provided on the surface of each inclined tooth to increase the frictional force when the inclined teeth mesh with each other, thereby ensuring the clamping force of the clamping device 2.

[0030] The present invention further provides a detachable shoulder strap 1, which includes a shoulder strap 1 and a shoulder strap clamping device 2 according to any of the above embodiments, disposed on both ends of the shoulder strap 1. By attaching the shoulder strap 1 to different bags 3, a user can achieve single- or double-shoulder carrying, freeing up both hands, and the shoulder strap 1 can enhance the fashionability of the bag 3. Furthermore, because the shoulder strap 1 is detachable and can be reused or attached to different bags 3, the same user does not need to carry multiple shoulder straps 1, which saves costs and promotes market penetration.

[0031] The above is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiment. All technical means that fall within the concept of the present invention are within the scope of protection of the present invention. [Explanation of symbols]
