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 use is to store changes of clothes, personal care products, and souvenirs from 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 labor is required, and production automation cannot be achieved. In addition, the plastic fasteners used in some travel bags are easily damaged, which affects the safety of travel bags.

[0003] Conventional frame connection 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 connection member made of a single material. For example, a plastic material may be deformed or fractured by being pulled by a high-strength tensile force. Metal materials are prone to rust or corrosion. In addition, when a travel bag in transit receives an external force, impact stress may occur. That is, the design adopting a single material cannot effectively prevent wear or damage, and is affected by environmental factors, so it cannot cope with different use environments.

[0004] Most frame connecting members of travel bags are not only relatively simple, but also lack structural reinforcement members, such as reinforcing ribs or reinforcing layers. When the travel bag is impacted during transportation, the frame connecting member has a relatively weak structure and is prone to deformation or fracture, resulting in the loss of the shell of the travel bag. Also, when the travel bag is compressed by overweight or external forces, the connecting part between the frame connecting member of the travel bag and the connecting site cannot effectively generate a repulsive force against the external pressure, causing the shell of the travel bag to deform. That is to say, if the reinforcement structure is not emphasized, the connection between the frame connecting member and the wire fastener will loosen, and after long-term use, it will affect the smoothness when opening and closing the travel bag.

[0005] In addition, the fastening design of the shell of the conventional travel bag is relatively simple, especially the connection part between the wire fastener and the frame connecting member is not strengthened. Therefore, when the travel bag is used for a long time or with high intensity, the wire fastener often comes off from the frame connecting member, making the shell of the travel bag unable to be opened and closed normally, and there is a risk that the wire fastener will get caught or broken.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In view of the above-mentioned drawbacks, the main purpose of the present invention is to provide a frame connection structure for a travel bag that can increase the structural strength of the travel bag and simplify the mounting operation.

Means for Solving the Problems

[0007] To solve the above problems, the frame connection structure of the travel bag includes a first shell, a second shell, a first frame connection member, a second frame connection member, a first engagement tooth member, a second engagement tooth member, and two connection 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 connection member has a first shell connection plate, a first connection part, a first fastener connection plate, a first shielding plate, and a first stopper. The first shell connection plate is connected to the first frame of the first shell. The first connection part is connected to the first shell connection plate. The first fastener connection plate is connected to the first connection part, and a first shell fitting groove is formed between the first fastener connection plate and the first shell connection plate. The first frame of the first shell is fitted into and mounted in the first shell fitting groove. The first shielding plate is connected to the first fastener connection plate to form a first fastener fitting groove. The first stopper is connected to the first connection part. The second frame connection member has a second shell connection plate, a second connection part, a second fastener connection plate, a second shielding plate, and a second stopper. The second shell connection plate is connected to the second frame of the second shell. The second connection part is connected to the second shell connection plate. The second fastener connection plate is connected to the second connection part, and a second shell fitting groove is formed between the second fastener connection plate and the second shell connection plate. The second frame of the second shell is fitted into and mounted in the second shell fitting groove. The second shielding plate is connected to the second fastener connection plate to form a second fastener fitting groove. The second stopper is connected to the second connection part. The first engagement tooth member has a first engagement tooth tape and a first engagement tooth head. The first engagement tooth tape is fitted into the first fastener fitting groove and is connected to the first fastener connection plate of the first frame connection member so as to correspond to the first stopper. The first engagement tooth head is arranged so as to be distributed on the first engagement tooth tape. The second engagement tooth member has a second engagement tooth tape and a second engagement tooth head. The second engagement tooth tape is fitted into the second fastener fitting groove and is connected to the second fastener connection plate of the second frame connection member so as to correspond to the second stopper. The second engagement tooth head is distributed on the first engagement tooth tape and is arranged so as to mesh with the first engagement tooth head of the first engagement tooth member. One connection unit connects the first frame of the first shell, the first shell connection plate and the first fastener connection plate of the first frame connection member, and the first engagement tooth tape of the first engagement 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 service tooth tape of the second service tooth member.

[0008] To sum up the above, the frame connection structure of the travel bag according to the present invention is designed to greatly enhance the structural strength of the entire shell by accurately combining a plurality of members. Specifically, the frame connection member is composed of a plurality of corresponding parts, such as a shell connecting plate, a fastener connecting plate, a shielding plate, and a stopper. These parts cooperate with each other to effectively disperse the external pressure, thereby strengthening the stability of the edge of the shell. At the same time, it can suppress deformation or damage caused by external forces, and extend the service life of the travel bag. The modular design can simplify the installation work of each member. Specifically, as long as the corresponding members are combined according to the design content, the installation work can be smoothly completed, the production efficiency can be improved, and at the same time, mistakes during the installation work can be reduced.

[0009] In a relatively preferable case, since the hardness of the first shell connecting plate, the first connecting part, and the first stopper of the first frame connecting member is greater than the hardness of the first fastener connecting plate and the first shielding plate, the structural strength can be enhanced.

[0010] In a relatively preferable case, since the hardness of the second shell connecting plate and the second connecting part of the second frame connecting member is greater than the hardness of the second fastener connecting plate and the second shielding plate, the structural strength can be enhanced.

[0011] In a relatively preferable 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 to improve the structural stability.

[0012] In a relatively preferable case, the second stopper of the second frame connecting member has a second stopper top surface. The second stopper top surface corresponds to the thickness of the second shell connecting plate to improve the structural stability.

[0013] In a relatively preferred case, the first frame connecting member has a first rib. The first rib is connected to the first shell connecting plate in a curved shape to reinforce the structure.

[0014] In a relatively preferred case, the second frame connecting member has a second rib. The second rib is connected to the second shell connecting plate in a curved shape to reinforce the structure.

[0015] In a relatively preferred case, the second stopper of the second frame connecting member and the first stopper of the first frame connecting member are combined to tightly connect the first frame connecting member and the second frame connecting member.

[0016] In a relatively preferred case, the two connecting units are sewing members, nailing members, riveting members, adhesive members or combinations thereof, so as to enhance the flexibility of the mounting operation and select an optimal connecting method according to actual needs.

[0017] The detailed structure, features, assembly or usage method of the frame connection structure of the travel bag according to the present invention will be clarified through the following detailed description of the embodiments. Also, the following detailed description and the embodiments presented by the present invention are merely examples for explaining the present invention, and it should be understandable to those with common sense in the field related to the present invention that the claims of the present invention cannot be limited.

Mode for Carrying Out the Invention

[0019] Hereinafter, the frame connection structure of the travel bag according to the present invention will be described with reference to the drawings. In the specification and the 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 toothed member 50, a second shell 20, a second frame connection member 40, a second toothed 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 toothed 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 toothed member.

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

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

[0024] The first frame connecting member 30 has 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 a first shell fitting groove 3a is formed between the first fastener connecting plate 33 and the first shell connecting plate 31. The first frame 11 of the first shell 10 is fitted into the first shell fitting groove 3a for attachment. The first shielding plate 34 is connected to the other end of the first fastener connecting plate 33 to form a 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 formed of the same material. The material is preferably ABS. The first fastener connecting plate 33 and the first shielding plate 34 are integrally formed of the same material. The material is preferably TPE. The hardness of the first shell connecting plate 31, the first connecting portion 32 and the first stopper 35 is greater than that of the first fastener connecting plate 33 and the first shielding plate 34. In other words, since the first frame connecting member 30 is made of two different materials for the shell connecting plate and the fastener connecting plate, it has good strength and elasticity when attaching the frame connecting member of the 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 between the first shell connecting plates 31. The first stopper 35 has a through hole for reducing weight.

[0027] The first shell connecting plate 31 and the first fastener connecting plate 33 are parts that are connected to the first frame 11 to connect the shell and the frame connecting member. Depending on the structure and material of the first shell connecting plate 31, the overall stability of the shell can be maintained after receiving external pressure. The first fastener connecting plate 33 is located on another side of the first shell connecting plate 31 and is indirectly connected to the first shell connecting plate. The first fastener connecting plate 33 is connected to the fastener tape of the duty tooth member to perform the opening and closing function of the shell. The first shielding plate 34 is connected to another end of the first fastener connecting plate 33 to suppress the exposure of the fastener, enhancing the appearance, texture, and safety during use of the travel bag. 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 deviation of the fastener during use.

[0028] Specifically, the combination of the above-mentioned parts and their respective functions can maintain the stability of the connection points of the travel bag and increase the toughness and impact resistance of the overall structure. To exhibit the best strength and elasticity, the first shell connecting plate 31 and the first fastener connecting plate 33 are made of two different materials. Such a design gives the frame connecting member good adaptability and at the same time can enhance the wear resistance or the ability to cope with specific situations of the frame connecting member during use. For example, if the first shell connecting plate 31 is made of a relatively hard plastic material or metal material, the structural stability can be enhanced. On the contrary, if the first fastener connecting plate 33 is made of a flexible synthetic material, the smoothness when opening and closing the fastener can be enhanced.

[0029] The first stopper 35 of the first frame connecting member 30 generates a supporting force corresponding to the first shell connecting plate 31 by the top surface 351 of the first stopper. When the first frame connecting member 30 and the first shell 10 are coupled, the top surface 351 of the first stopper effectively suppresses the loosening or displacement of the frame connecting member, and can ensure the stability when opening and closing the travel bag. That is, such a design can enhance the durability of the structure and suppress the risk of damage caused by excessive wear over long-term use.

[0030] As shown in FIGS. 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 coupled 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 for mounting. 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 formed of the same material. It is preferable that the material is ABS. The second fastener connecting plate 43 and the second shielding plate 44 are integrally formed of the same material. It is preferable that the material is TPE. The hardness of the second shell connecting plate 41, the second connecting portion 42, and the second stopper 45 is greater than that of the second fastener connecting plate 43 and the second shielding plate 44. In other words, since the shell connecting plate and the fastener connecting plate of the second frame connecting member 40 are made of two different materials, it has good strength and elasticity when mounting the frame connecting member of the travel bag. Further, the present invention is not limited to the above, and materials that can cope with different environments according to different needs, such as wear resistance, can be used to improve the performance of the product.

[0032] In the present 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 the thickness of the second shell connecting plate 41, but is not limited thereto. The second stopper 45 has a through hole for reducing weight. The second stopper 45 and the first stopper 35 of the first frame connecting member 30 are correspondingly fitted together.

[0033] As shown in FIGS. 2 to 6, the first duty tooth member 50 strengthens the connecting portion corresponding to the first frame connecting member 30 and performs the opening and closing function of the travel bag. The first duty tooth member 50 has a first duty tooth tape 51 and a first duty tooth head 52. The first duty tooth head 52 is arranged so as to be distributed on the first duty tooth tape 51. The first duty tooth tape 51 is connected to the first fastener connecting plate 33 of the first frame connecting member 30 so as to correspond to the first stopper 35.

[0034] As shown in FIGS. 2 to 6, the second working tooth member 60 corresponds to the second frame connecting member 40 and serves to open and close the joint portion between the second shell 20 and the first shell 10. The second working tooth member 60 has a second working tooth tape 61 and a second working tooth head 62. The second working tooth head 62 is arranged so as to be distributed on the second working tooth tape 61. The second working 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 working tooth head 62 is arranged so as to mesh with the first working tooth head 52 of the first working tooth member 50. The first working tooth member 50 and the second working tooth member 60 constitute a wire fastener.

[0035] As shown in FIGS. 2 to 6, in the present embodiment, the two connecting units 70 are sewing members. That is, one connecting unit 70 stitches together 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 working tooth tape 51 of the first working tooth member 50 with sewing thread. The other connecting unit 70 stitches together 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 working tooth tape 61 of the second working tooth member 60 with sewing thread. The two connecting units 70 are sewing members, but are not limited thereto, and may be nailing members, riveting members, adhesive members, or a combination of two or more of them.

[0036] Due to the above-mentioned structural features, the frame connection structure of the travel bag can achieve firmness and simplification of the mounting operation, thus achieving the purpose of the present invention. Specifically speaking, with such a design, the engaging member is more firmly connected to the frame connecting member. The first stopper 35 and the second stopper 45 can prevent the fasteners in use from deviating, and can ensure the smoothness and durability of the fasteners. Summing up the above, the design of the frame connection structure of the travel bag according to the present invention skillfully combines strength, elasticity and convenience, and improves the overall durability and operating performance through the selection of materials and the innovation of the structure. Therefore, the present invention is significantly superior to the prior art, and can greatly improve the structural strength, durability and stability of the fasteners. In addition, the present invention can greatly improve the overall performance of the travel bag by using two different materials, structural reinforcement and firm fasteners, can not only solve many drawbacks of the conventional travel bag, but also provide a feasible technology for upgrading the product.

[0037] (Another embodiment) Figures 7 to 11 are schematic diagrams showing the frame connection structure of a travel bag according to another embodiment of the present invention. The differences from the above-described embodiment are as follows. In another embodiment, the first frame connecting member 30 further has a first rib 37. The first rib 37 is curvedly connected to the first shell connecting plate 31 to reinforce the structure of the first frame connecting member 30. The second frame connecting member 40 has a second rib 47. The second rib 47 is curvedly connected to the second shell connecting plate 41 to reinforce the structure of the second frame connecting member 40. That is, the present invention enhances the stability of the frame connecting member by a plurality of ribs, and improves the pressure resistance performance and deformation resistance performance of the travel bag. Therefore, the travel bag can not only withstand the external force during transportation, but also has high durability and damage resistance, that is, the purpose of the present invention can be achieved.

[0038] Specifically, in the present invention, 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, the stability of the frame connecting member is enhanced, a force is generated to support the frame connecting member, so that the pressure resistance performance and deformation resistance performance of the traveling backpack during transportation are improved, the damage of the shell by external forces is suppressed, and the durability and damage resistance can be improved, that is, the object of the present invention can be achieved.

[0039] In addition to the above-described embodiments, the structure of the present invention can be changed.

[0040] For example, the second shell 20, the second frame connecting member 40, and the second working tooth member 60 and the first shell 10, the first frame connecting member 30, and the first working tooth member 50 do not necessarily have the same structure. That is, the present invention can combine different structures. Further, the present invention can also adjust the materials of the frame connecting member and the working tooth member according to different use environments.

[0041] The above content has described several possible implementation methods of the present invention relatively specifically and in detail, but it does not limit the claims of the present invention. Those skilled in the art can understand that making some modifications and improvements without departing from the concept of the present invention is included within the protection scope. Therefore, the protection scope of the present invention should be based on the scope of the claims.

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