Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically a segmented luggage frame structure. Background Technology

[0002] A zippered suitcase is a type of travel suitcase. Zippered suitcases are lightweight and easy to carry on long trips. They also offer some space expansion when packed, making it more convenient to store items.

[0003] For example, Chinese patent application CN221813372U discloses a zipper structure and a box body for connecting the upper and lower shells of the box body. It includes two zipper bodies, each comprising a zipper fabric and a rib. One end of the zipper fabric has a first zipper tooth, and the other end is used to connect to the inner lining of the box body. The first zipper tooth engages with the first zipper tooth of the other zipper body. The rib is connected to the zipper fabric. By fixing the rib to the box body, the zipper body is fixed to the box body. Through the assembly of the rib and the box body's groove, the zipper fabric is bent and placed into a pre-set groove in the box body. The rib then provides initial positioning of the zipper fabric. Finally, fasteners or adhesives are used to fix the rib to the box body, thereby replacing manual sewing, reducing operational difficulty, and improving assembly yield.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the assembly method lacks pre-assembly design, and the processes of placing the zipper fabric, assembling the keel, and fixing the fasteners need to be completed step by step. The assembly continuity between the zipper fabric, the keel, and the box body is poor, and the pre-assembly of the zipper fabric and the keel cannot be achieved, resulting in a cumbersome overall processing procedure and difficulty in further improving production efficiency.

[0005] To address the shortcomings of the existing technology, a segmented bag frame structure is proposed to solve the aforementioned problems. Utility Model Content

[0035] 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.

[0036] like Figure 1-7As shown, this utility model provides a technical solution: a segmented bag frame structure, including an upper connecting part 1 and a lower connecting part 2 located on the bag body 14, two first zipper fabrics 5 and two second zipper fabrics 12. The upper connecting part 1 and the lower connecting part 2 are rotatably connected by a movable part, such as a hinge. One end of the first zipper fabric 5 is fixed with a first zipper tooth 6, and one end of the second zipper fabric 12 is fixed with a second zipper tooth 8. The first zipper teeth 6 of the two first zipper fabrics 5 mesh with each other. The first zipper fabrics 5 and the second zipper fabrics 12 are flexible fabrics adapted to the opening and closing of the bag body 14. One end of the first zipper tooth 6 is fixed and exposed for opening and closing engagement of the box body 14. The other end of the second zipper cloth 12 is fixed with a second zipper tooth 8, which is used to engage with the third zipper tooth 10 on the inner lining cloth 9 of the upper connecting part 1 and the lower connecting part 2, so as to realize the detachable connection of the inner lining cloth 9. The upper and lower connecting parts 1 and 2 are both provided with mounting grooves 3. The mounting grooves 3 are provided with frame edge components 4. The inner sides of the upper connecting part 1 and the lower connecting part 2 are both provided with annular mounting grooves 3. The cross-sectional contour of the mounting groove 3 is adapted to the enclosing frame edge 13 of the frame edge component 4, and is used to accommodate and position the frame edge component 4.

[0037] The frame component 4 includes a surrounding frame 13, which has a through mounting groove 7 along its length. One side of the mounting groove 7 has an opening 17 that communicates with the outside, allowing the first zipper teeth 6 of the two first zipper fabrics 5 to be exposed for engagement.

[0038] like Figure 3 As shown, it also includes a clip 16, which is sandwiched between the first zipper fabric 5 and the second zipper fabric 12 and connected to them. The clip 16, the first zipper fabric 5 and the second zipper fabric 12 are inserted from one end of the enclosure frame 13 to the other end along the extension direction of the assembly groove 7, so that the first zipper fabric 5 and the second zipper fabric 12 surround to form a loop structure and are completely embedded in the assembly groove 7, so that the zipper fabric is pre-installed on the enclosure frame 13.

[0039] In use, first clamp the clip 16 between the first zipper fabric 5 and the second zipper fabric 12. Using a detachable connection method, attach hook and loop fasteners to the bonding surface and sew loop and loop fasteners to the corresponding zipper fabric. Through hook and loop engagement, the first zipper fabric 5 and the second zipper fabric 12 are fixed to both sides of the clip 16.

[0040] The clip 16 is then inserted into the mounting groove 7 along the edge of the enclosure 13 from one end and pushed at a constant speed to the other end along the length of the mounting groove 7. The cross-sectional profile of the mounting groove 7 is adapted to the profile of the clip 16 and the zipper fabric, so that the zipper fabric surrounds the edge of the enclosure 13 to form a loop structure and is completely embedded in the mounting groove 7, thus completing the pre-installation.

[0041] The entire enclosure frame 13, pre-installed with zipper fabric and clip 16, is embedded into the mounting groove 3 of the upper connecting part 1 or the lower connecting part 2. Subsequently, the frame component 4 is fixed to the box body 14 by the fastener 11, thus realizing the rapid assembly of the zipper structure and the box body 14.

[0042] The first embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, the cross-section of the clip 16 has a combined structure, integrally formed from a circular area and a rectangular area. The cross-sectional shape of the clip 16 is adapted to the inner wall contour of the assembly groove 7 and the contact surfaces of the two zipper fabrics. The circular area of ​​the clip 16 is mainly used to fit against the corresponding arc-shaped inner wall of the assembly groove 7. Utilizing the uniform force distribution of the circular structure, it ensures accurate positioning of the clip 16 within the assembly groove 7 and reduces resistance during insertion. The rectangular area, through two flat planes, tightly fits against the two pieces of the first zipper fabric 5, increasing the contact area, improving clamping stability, and preventing relative slippage of the zipper fabric on the clip 16.

[0043] The second embodiment, such as Figure 5 and Figure 7 As shown, the cross-section of the clip 16 has a combined structure, integrally formed from an irregular circular area and a Z-shaped area. The two mating surfaces of the Z-shaped area are tightly fitted to the two zipper fabrics, and the cross-sectional shape of the clip 16 is adapted to the inner wall contour of the assembly groove 7 and the mating surfaces of the two zipper fabrics. The irregular circular area, which can be an ellipse or a circle with straight edges, is located on the inner side of the assembly groove 7, while the Z-shaped area is located on the side closer to the opening 17 of the assembly groove 7. In addition, during assembly, the second zipper fabric 12 can be stacked on the outside of the first zipper fabric 5 and fixed to the clip 16 by sewing, and then pushed into the assembly groove 7. The irregular circular area is fitted and positioned against the inner wall of the assembly groove, and the Z-shaped area faces the opening 17 of the assembly groove, so that the first zipper tooth 6 and the second zipper tooth 8 are exposed.

[0044] Furthermore, the dimensions of each area of ​​the cross-section of the clip 16 match the cross-sectional dimensions of the mounting groove 7. The total width of the clip 16 is not greater than the width of the mounting groove 7, and the total thickness is not greater than the depth of the mounting groove 7, ensuring that the clip 16 is fully embedded in the mounting groove 7 after clamping the zipper fabric. This dimensional fit ensures that the clip 16 and the zipper fabric can be smoothly inserted into the mounting groove 7, and that after full embedding, the mounting groove 7 will not deform due to excessive size, or loosen or shift due to insufficient size.

[0045] Furthermore, after the upper connecting part 1 and the lower connecting part 2 are closed, the bottom edges of the opposite surfaces of the upper connecting part 1 and the lower connecting part 2 are angled structures 18 facing the inside of the box 14. The angled structure 18 is an inverted L-shaped fold, which can increase the support strength of the upper connecting part 1 and the lower connecting part 2.

[0046] Furthermore, such as Figure 5As shown, the outer surface of the enclosing frame 13 has a slot 15 extending along its length. The slot 15 has a rectangular, U-shaped, or stepped cross-section. The fastener 11 passes through the bottom of the slot 15 through the enclosing frame 13 and extends into the mounting groove 3, thus fixing the enclosing frame 13 to the mounting groove 3. An aesthetic strip (not shown in the figure) adapted to the shape and size of the slot 15 is embedded in the slot 15. The aesthetic strip completely covers the exposed part of the fastener 11 in the slot 15, and the outer surface of the aesthetic strip is flush with or lower than the outer surface of the enclosing frame 13, so that the aesthetic strip is located at the outermost layer of the bag frame structure. After the aesthetic strip is embedded in the slot 15, it can cover the processing marks on the outer surface of the enclosing frame 13. At the same time, different colors and materials of aesthetic strips can be selected according to the overall style of the bag, enhancing the diversity and texture of the product appearance. The snap-fit ​​design makes it easy to replace the decorative strip. If the decorative strip is worn out or the user wants to change the style, the old decorative strip can be directly removed and a new decorative strip can be inserted.

[0047] Furthermore, one end of each of the two second zipper teeth 8 engages with the third zipper teeth 10 on the inner lining fabric 9 of the upper and lower connecting parts 1 and 2, respectively. When the inner lining fabric 9 needs to be installed, simply align and engage the third zipper teeth 10 on the inner lining fabric 9 with the second zipper teeth 8 on the second zipper fabric 12 to quickly complete the fixing. One end of each of the two first zipper teeth 6 engages with the inner lining fabric 9.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0049] like Figure 7 As shown, this utility model provides a technical solution: a segmented bag frame structure, wherein at least two fixing members 11 are provided on the enclosing frame 13. The fixing members 11 are spaced apart along the circumference of the enclosing frame 13 to ensure that the enclosing frame 13 is subjected to uniform force and avoid deformation caused by local stress concentration. They are used to fix the enclosing frame 13 pre-installed with zipper fabric into the mounting groove 3. After the plastic enclosing frame 13 is embedded into the mounting groove 3, the evenly distributed fixing members 11 act on different circumferential positions of the enclosing frame 13, so that the outer surface of the enclosing frame 13 is fully in contact with the groove wall of the mounting groove 3. The limiting effect of the fixing members 11 prevents the enclosing frame 13 from sliding or shifting circumferentially within the mounting groove 3.

[0050] The fastener 11 passes sequentially through the upper connecting part 1 and the enclosing frame edge 13 on the upper connecting part 1, and sequentially through the lower connecting part 2 and the enclosing frame edge 13 on the lower connecting part 2. After the fastener 11 passes through the enclosing frame edge 13 and the box body 14, it securely fixes the enclosing frame edge 13 in the mounting groove 3 through the cooperation of the rod part and the mounting hole, thereby achieving a rigid connection between the frame edge and the box body 14.

[0051] Meanwhile, the fastener 11 is a rivet, and mounting holes adapted to the fastener 11 are correspondingly provided on the walls of the surrounding frame 13 and the mounting groove 3. Mounting holes are also correspondingly provided on the side walls of the surrounding frame 13 and the groove walls of the mounting groove 3, and the diameter of the mounting holes is adapted to the diameter of the rod portion of the fastener 11. The fastener 11 achieves a good fixing effect through its adapted fit with the mounting holes.

[0052] Furthermore, such as Figure 1-3 As shown, two fasteners (11) are provided on the enclosure frame (13). The enclosure frame (13) is made of aluminum. The beginning and end ends of the enclosure frame (13) are fixed in the mounting groove (3) by a fastener (11). By fixing the beginning and end ends by the two fasteners (11), the displacement of the enclosure frame (13) can be restricted, ensuring that the relative position of the frame and the mounting groove 3 remains unchanged.

[0053] In summary, this segmented bag frame structure first places the clip 16 between the first zipper fabric 5 and the second zipper fabric 12, and then attaches hook and loop fasteners to the bonding surface and sews loop fasteners to the corresponding zipper fabric. Through hook and loop engagement, the first zipper fabric 5 and the second zipper fabric 12 are fixed to the clip 16. Then, the clip 16 is passed through the assembly groove 7 of the frame 13 to the other end, so that the zipper fabric is wrapped around to form a loop structure and completely embedded in the assembly groove 7 to complete the pre-installation.

[0054] The enclosure frame 13 is then embedded into the mounting groove 3 of the upper connecting part 1 or the lower connecting part 2. Fixing members 11, evenly distributed around the circumference of the enclosure frame 13, sequentially penetrate the enclosure frame 13 and the box body 14, thus fixing the frame component 4 to the box body 14 and limiting the zipper fabric and locking strip 16. After the upper connecting part 1 and the lower connecting part 2 are closed, the box body 14 is opened and closed by the engagement of the first zipper teeth 6 on the two first zipper fabrics 5. The second zipper teeth 8 engage with the third zipper teeth 10 of the inner lining fabric 9 to achieve a detachable connection of the inner lining fabric 9. The decorative strip on the outer surface of the enclosure frame 13 enhances the appearance and wear resistance.

[0055] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
