Description

Technical Field

[0001] The present invention relates to a travel bag, and more particularly to a frame connection structure of a travel bag.

Background Art

[0002] Travel bags such as suitcases and trolley bags are boxes for storing items to be carried when going out, and their purpose of use is to store clothes to change, personal care products, and souvenirs at the travel destination. Travel bags on the market are divided into expandable travel bags with wire fasteners (i.e., boxes with wire fasteners) and housing-type travel bags (i.e., housing boxes). Boxes with wire fasteners are characterized by being small and lightweight, so they are accepted by many people. However, in the production process of boxes with wire fasteners, the operation of attaching the box body is not easy, the wire fasteners need to be sewn by hand, a lot of manpower is required, and production automation cannot be achieved. In addition, plastic fasteners used in some travel bags are easily damaged, which affects the safety of travel bags.

[0003] Conventional frame connecting members and wire fasteners of travel bags are made of a single material, that is, a plastic material or a metal material. However, when using a travel bag, the defects of other materials affect the overall performance of the frame connecting member made of a single material. For example, a plastic material may be deformed or broken by being pulled by a high-strength tensile force. A metal material is likely to rust or corrode. In addition, when a travel bag in transit receives an external force, an impact stress may occur. That is, the design adopting a single material cannot effectively prevent wear or breakage, is affected by environmental factors, and cannot cope with different use environments.

[0004] Many suitcases have relatively simple frame connecting members, and often lack structural reinforcement, such as reinforcing ribs or layers. When a suitcase is subjected to impact during transport, the frame connecting members are structurally weak and prone to deformation or breakage, damaging the suitcase shell. Furthermore, when a suitcase is compressed by excessive weight or external force, the frame connecting members and connecting points cannot effectively generate resilience against external pressure, causing deformation of the suitcase shell. In short, if reinforcement is not prioritized, the connection between the frame connecting members and the zipper will loosen, affecting the smoothness of opening and closing the suitcase after prolonged use.

[0005] Furthermore, conventional travel bags have a relatively simple shell fastening design, and the connection between the zipper and the frame connecting member is not reinforced. As a result, when a travel bag is used for a long time or under high stress, the zipper often comes off the frame connecting member, preventing the travel bag's shell from opening and closing properly, and potentially causing the zipper to get stuck or break. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] In view of the aforementioned drawbacks, the main objective of this invention is to provide a travel bag frame connecting structure that can increase the structural strength of the travel bag and simplify the attachment process. [Means for solving the problem]

[0007] To solve the above-mentioned problems, the frame connecting structure of the travel bag comprises a first shell, a second shell, a first frame connecting member, a second frame connecting member, a first tooth member, a second tooth member, and two connecting units. The first shell has a first frame. The second shell has a second frame corresponding to the first frame of the first shell. The first frame connecting member comprises a first shell connecting plate, a first connecting portion, a first fastener connecting plate, a first shielding plate, and a first stopper. The first shell connecting plate is connected to the first frame of the first shell. The first connecting portion is connected to the first shell connecting plate. The first fastener connecting plate is connected to the first connecting portion, and the space between it and the first shell connecting plate becomes the first shell fitting groove. The first frame of the first shell is fitted into the first shell fitting groove and installed. The first shielding plate is connected to the first fastener connecting plate to form the first fastener fitting groove. The first stopper is connected to the first connecting portion. The second frame connecting member comprises a second shell connecting plate, a second connecting portion, a second fastener connecting plate, a second shielding plate, and a second stopper. The second shell connecting plate is connected to the second frame of the second shell. The second connecting portion is connected to the second shell connecting plate. The second fastener connecting plate is connected to the second connecting portion, and the space between it and the second shell connecting plate becomes the second shell fitting groove. The second frame of the second shell is fitted into the second shell fitting groove and installed. The second shielding plate is connected to the second fastener connecting plate to form the second fastener fitting groove. The second stopper is connected to the second connecting portion. The first tooth member has a first tooth tape and a first tooth head. The first tooth tape fits into the first fastener fitting groove and is connected to the first fastener connecting plate of the first frame connecting member so as to correspond to the first stopper. The first tooth heads are arranged so as to be distributed on the first tooth tape. The second tooth member has a second tooth tape and a second tooth head. The second tooth tape fits into the second fastener fitting groove and is connected to the second fastener connecting plate of the second frame connecting member so as to correspond to the second stopper. The second tooth heads are distributed on the first tooth tape and are positioned to interlock with the first tooth heads of the first tooth member. One connecting unit connects the first frame of the first shell, the first shell connecting plate and the first fastener connecting plate of the first frame connecting member, and the first tooth tape of the first tooth member.Another connecting unit connects the second frame of the second shell, the second shell connecting plate and the second fastener connecting plate of the second frame connecting member, and the second tooth tape of the second tooth member.

[0008] In summary, the frame connection structure for a travel bag according to this invention is designed to significantly increase the overall structural strength of the shell by precisely combining multiple components. More specifically, the frame connection components consist of multiple interconnected parts, such as shell connection plates, zipper connection plates, shielding plates, and stoppers. These components cooperate with each other to effectively distribute external pressure, thereby strengthening the stability of the shell's edges, while simultaneously suppressing deformation or damage caused by external forces, and extending the lifespan of the travel bag. The modular design simplifies the assembly process of each component. More specifically, by simply combining interconnected components according to the design, the assembly process can be completed smoothly, improving production efficiency and simultaneously reducing errors during the assembly process.

[0009] In relatively favorable cases, the hardness of the first shell connecting plate, first connecting portion, and first stopper of the first frame connecting member is greater than the hardness of the first fastener connecting plate and first shielding plate, thus increasing structural strength.

[0010] In relatively favorable cases, the hardness of the second shell connecting plate and the second connecting portion of the second frame connecting member is greater than the hardness of the second fastener connecting plate and the second shielding plate, thereby increasing the structural strength.

[0011] In a relatively favorable case, the first stopper of the first frame connecting member has a first stopper top surface. The first stopper top surface corresponds to the thickness of the first shell connecting plate, thereby improving the stability of the structure.

[0012] In relatively preferable cases, the second stopper of the second frame connecting member has a second stopper top surface. The second stopper top surface improves structural stability by corresponding to the thickness of the second shell connecting plate.

[0013] In relatively preferable cases, the first frame connecting member has a first rib. The first rib reinforces the structure by being connected to the first shell connecting plate in a curved manner.

[0014] In relatively preferable cases, the second frame connecting member has a second rib. The second rib reinforces the structure by being connected to the second shell connecting plate in a curved manner.

[0015] In relatively favorable cases, the second stopper of the second frame connecting member and the first stopper of the first frame connecting member come together to tightly connect the first frame connecting member and the second frame connecting member.

[0016] In relatively preferable cases, the two connecting units may be sewn, nailed, riveted, glued, or a combination thereof, thus increasing the flexibility of the installation process and allowing the optimal connecting method to be selected according to the actual needs.

[0017] The detailed structure, features, assembly, and method of use of the travel bag frame connecting structure according to this invention will be clarified through the detailed description of the embodiments below. Furthermore, it should be understood by anyone with common sense in the field of this invention that the following detailed description and the embodiments presented herein are merely examples for explaining this invention and do not limit the scope of the claims of this invention.

MODE FOR CARRYING OUT THE INVENTION

[0019] Hereinafter, the frame connection structure of the travel bag according to the present invention will be described based on the drawings. In the specification and drawings, the directional terms are expressed based on the directions in the drawings. The same reference numerals indicate the structural features of the same parts or similar parts.

[0020] (One embodiment) As shown in FIGS. 1 and 2, the frame connection structure of the travel bag according to an embodiment of the present invention includes a first shell 10, a first frame connection member 30, a first duty tooth member 50, a second shell 20, a second frame connection member 40, a second duty tooth member 60, and two connection units 70.

[0021] As shown in FIGS. 2 to 6, the first shell 10, that is, the half case of the travel bag, has a first frame 11. The first frame 11 is a part where the frame connection member and the duty tooth member of the travel bag are separately connected, which can maintain the strength stability and at the same time increase the overall structural strength of the travel bag by tightly connecting the frame connection member and the duty tooth member.

[0022] As shown in Figures 2 to 6, the second shell 20, i.e., another half case of the travel bag, and the first shell 10 combine to form the overall structure of the travel bag. The second shell 20 has a second frame 21 that corresponds to the first frame 11 of the first shell 10.

[0023] As shown in Figures 2 to 6, the first frame connecting member 30 is attached to the edge of the first shell 10, connecting the shell of the travel bag to the gear member and enhancing structural stability.

[0024] The first frame connecting member 30 includes a first shell connecting plate 31, a first connecting portion 32, a first fastener connecting plate 33, a first shielding plate 34, and a first stopper 35. The first shell connecting plate 31 is connected to the first frame 11 of the first shell 10. The first connecting portion 32 is connected to the first shell connecting plate 31. The first fastener connecting plate 33 is connected to the first connecting portion 32, and the space between it and the first shell connecting plate 31 forms the first shell fitting groove 3a. The first frame 11 of the first shell 10 is fitted into the first shell fitting groove 3a and installed. The first shielding plate 34 is connected to the other end of the first fastener connecting plate 33 to form the first fastener fitting groove 3b. The first stopper 35 is connected to the first connecting portion 32.

[0025] In the first frame connecting member 30, the first shell connecting plate 31, the first connecting portion 32, and the first stopper 35 are integrally molded from the same material. ABS is preferred as the material. The first fastener connecting plate 33 and the first shielding plate 34 are integrally molded from the same material. TPE is preferred as the material. The hardness of the first shell connecting plate 31, the first connecting portion 32, and the first stopper 35 is greater than the hardness of the first fastener connecting plate 33 and the first shielding plate 34. In other words, because the shell connecting plate and the fastener connecting plate of the first frame connecting member 30 are made from two different materials, it has good strength and elasticity when attaching the frame connecting member of a travel bag.

[0026] In this embodiment, the first stopper 35 of the first frame connecting member 30 has a first stopper top surface 351. The first stopper top surface 351 corresponds to, but is not limited to, the thickness of the first shell connecting plate 31. The first stopper 35 has through holes to reduce weight.

[0027] The first shell connecting plate 31 and the first fastener connecting plate 33 are parts that connect the shell to the frame connecting member by being connected to the first frame 11. Due to the structure and material of the first shell connecting plate 31, the overall stability of the shell can be maintained even when subjected to external pressure. The first fastener connecting plate 33 is located on the other side of the first shell connecting plate 31 and is indirectly connected to the first shell connecting plate. The first fastener connecting plate 33 performs the opening and closing function of the shell by being connected to the tooth tape of the tooth member. The first shielding plate 34 is connected to the other end of the first fastener connecting plate 33 to suppress the exposure of the fastener, improving the appearance, texture and safety of the travel bag during use. The first stopper 35 is formed at the end of the first shell connecting plate 31 and is connected to other parts of the frame connecting member to maintain stability and at the same time suppress the prolapse of the fastener during use.

[0028] More specifically, the combination of the parts described above and their respective functions maintain the stability of the travel bag's connecting points and increase the overall toughness and impact resistance of the structure. To achieve optimal strength and elasticity, the first shell connecting plate 31 and the first zipper connecting plate 33 are made from two different materials. Such a design allows for good adaptability to the frame connecting members and simultaneously enhances the wear resistance or ability of the frame connecting members to cope with specific situations during use. For example, if the first shell connecting plate 31 is made from a relatively hard plastic or metal material, the stability of the structure can be increased. Conversely, if the first zipper connecting plate 33 is made from a flexible synthetic material, the smoothness of opening and closing the zipper can be improved.

[0029] The first stopper 35 of the first frame connecting member 30 generates a supporting force corresponding to the first shell connecting plate 31 via the first stopper top surface 351. When the first frame connecting member 30 and the first shell 10 are joined, the first stopper top surface 351 effectively prevents the frame connecting member from loosening or displacing, ensuring stability when opening and closing the travel bag. In other words, such a design enhances the durability of the structure and reduces the risk of damage due to excessive wear over long-term use.

[0030] As shown in Figures 2 to 6, the second frame connecting member 40 corresponds to the first frame connecting member 30 and is connected to the second shell 20. The second frame connecting member 40 has a second shell connecting plate 41, a second connecting portion 42, a second fastener connecting plate 43, a second shielding plate 44, and a second stopper 45. The second shell connecting plate 41 is connected to the second frame 21 of the second shell 20. The second connecting portion 42 is connected to the second shell connecting plate 41. The second fastener connecting plate 43 is connected to the second connecting portion 42 and is connected to the second frame 21 of the second shell 20. The second shell connecting plate 41 has a second shell fitting groove 4a between it and the second fastener connecting plate 43. The second frame 21 of the second shell 20 is fitted into the second shell fitting groove 4a and mounted. The second shielding plate 44 is connected to the other end of the second fastener connecting plate 43 to form a second fastener fitting groove 4b. The second stopper 45 is connected to the second connecting portion 42.

[0031] In the second frame connecting member 40, the second shell connecting plate 41, the second connecting portion 42, and the second stopper 45 are integrally molded from the same material. ABS is preferred as the material. The second fastener connecting plate 43 and the second shielding plate 44 are integrally molded from the same material. TPE is preferred as the material. The hardness of the second shell connecting plate 41, the second connecting portion 42, and the second stopper 45 is greater than the hardness of the second fastener connecting plate 43 and the second shielding plate 44. In other words, because the shell connecting plate and the fastener connecting plate of the second frame connecting member 40 are made from two different materials, it has good strength and elasticity when attaching the frame connecting member of a travel bag. Furthermore, this invention is not limited to the above, and the performance of the product can be improved by using materials that can be adapted to different environments according to different needs, such as wear resistance.

[0032] In this embodiment, the second stopper 45 of the second frame connecting member 40 has a second stopper top surface 451. The second stopper top surface 451 corresponds to, but is not limited to, the thickness of the second shell connecting plate 41. The second stopper 45 has a through hole to reduce weight. The second stopper 45 and the first stopper 35 of the first frame connecting member 30 are mutually corresponding and fit together.

[0033] As shown in Figures 2 to 6, the first tooth member 50 reinforces the connection portion in correspondence with the first frame connecting member 30 and performs the opening and closing function of the travel bag. The first tooth member 50 has a first tooth tape 51 and a first tooth head 52. The first tooth head 52 is arranged to be distributed on the first tooth tape 51. The first tooth tape 51 is connected to the first fastener connecting plate 33 of the first frame connecting member 30 in correspondence with the first stopper 35.

[0034] As shown in Figures 2 to 6, the second tooth member 60 corresponds to the second frame connecting member 40 and is useful for opening and closing the joint between the second shell 20 and the first shell 10. The second tooth member 60 has a second tooth tape 61 and a second tooth head 62. The second tooth head 62 is positioned to be distributed on the second tooth tape 61. The second tooth tape 61 is connected to the second fastener connecting plate 43 of the second frame connecting member 40 so as to correspond to the second stopper 45. The second tooth head 62 is positioned to interlock with the first tooth head 52 of the first tooth member 50. The first tooth member 50 and the second tooth member 60 constitute a wire fastener.

[0035] As shown in Figures 2 to 6, in this embodiment, the two connecting units 70 are sewing members. That is, one connecting unit 70 connects the first frame 11 of the first shell 10, the first shell connecting plate 31 and the first fastener connecting plate 33 of the first frame connecting member 30, and the first tooth tape 51 of the first tooth member 50 with sewing thread. The other connecting unit 70 connects the second frame 21 of the second shell 20, the second shell connecting plate 41 and the second fastener connecting plate 43 of the second frame connecting member 40, and the second tooth tape 61 of the second tooth member 60 with sewing thread. The two connecting units 70 are sewing members, but are not limited to this, and may be nailing members, rivet members, adhesive members, or two or more combinations thereof.

[0036] Due to the structural features described above, the frame connection structure of the travel bag achieves robustness and simplifies the assembly process, thus achieving the objectives of this invention. More specifically, this design allows the zipper teeth to be more firmly connected to the frame connection members. The first stopper 35 and the second stopper 45 prevent the zipper from coming loose during use, ensuring the smoothness and durability of the zipper. In summary, the design of the travel bag frame connection structure according to this invention skillfully combines strength, elasticity, and convenience, and improves overall durability and operability through the selection of materials and structural innovation. Therefore, this invention is significantly superior to conventional technology, and can greatly improve structural strength, durability, and zipper stability. Furthermore, this invention significantly improves the overall performance of the travel bag through two different materials, structural reinforcement, and a robust zipper, not only solving many of the shortcomings of conventional travel bags but also providing a feasible technology for upgrading the product.

[0037] (Another embodiment) Figures 7 to 11 are schematic diagrams showing a frame connection structure of a travel bag according to another embodiment of the present invention. The differences from the embodiment described above are as follows. In this other embodiment, the first frame connection member 30 further has a first rib 37. The first rib 37 is connected to the first shell connection plate 31 in a curved manner, thereby reinforcing the structure of the first frame connection member 30. The second frame connection member 40 has a second rib 47. The second rib 47 is connected to the second shell connection plate 41 in a curved manner, thereby reinforcing the structure of the second frame connection member 40. In other words, the present invention enhances the stability of the frame connection members with multiple ribs, improving the compression resistance and deformation resistance of the travel bag. As a result, the travel bag can not only withstand external forces during transport, but also have increased durability and damage resistance, thus achieving the objective of the present invention.

[0038] More specifically, this invention enhances the stability of the frame connecting members by separately adding curved first ribs 37 and second ribs 47 to the first frame connecting member 30 and the second frame connecting member 40, thereby generating a supporting force for the frame connecting members. This improves the compression resistance and deformation resistance of the travel bag during transport, suppresses damage to the shell due to external forces, and improves durability and damage resistance, thus achieving the objective of this invention.

[0039] The structure of this invention can be modified in addition to the embodiments described above.

[0040] For example, the second shell 20, second frame connecting member 40, and second tooth member 60 do not necessarily have the same structure as the first shell 10, first frame connecting member 30, and first tooth member 50. In other words, this invention allows for the combination of different structures. Furthermore, this invention allows for the adjustment of the materials of the frame connecting members and tooth members according to different usage environments.

[0041] The above description provides a relatively specific and detailed explanation of some possible methods of the present invention, but does not limit the scope of the claims. Those skilled in the art will understand that minor modifications and improvements, without departing from the concept of the present invention, are included within the scope of protection. Therefore, the scope of protection of the present invention should be based on the registered claims.

[0042] As stated above, the present invention is not limited in any way to the embodiments described above, and can be implemented in various forms without departing from the spirit of the invention. [Explanation of Symbols]
