Abstract
Description
Technical Field
[0001] This utility model relates to a suitcase, and more particularly to a suitcase edge assembly structure. Background Technology
[0002] A suitcase, also known as a travel case or rolling case, is a box used to carry belongings when traveling; it is a type of luggage. Suitcases are typically used to hold clothing, personal care items, and souvenirs needed for a trip. Currently, suitcases on the market can be broadly divided into two types: zippered suitcases and framed suitcases. Zippered suitcases are lighter and more compact, making them popular. However, existing zippered suitcases suffer from several drawbacks during production. Assembly is inconvenient, as the zippers require manual sewing, necessitating more manpower and hindering automated production. Some models use plastic snap-on zippers, but these are prone to breakage, resulting in lower security.
[0003] Many traditional suitcases are known to use a single material for their seams and zippers, commonly either all-plastic or metal. Seams made of a single material are prone to performance degradation due to defects in that material. For example, plastic may deform or break under high-intensity tension, while metal may rust or corrode easily. Suitcases are frequently subjected to impacts during transport, and a single-material design may not effectively prevent wear and tear. Furthermore, single-material designs are less adaptable to different environments and are easily affected by environmental factors.
[0004] Many suitcases on the market currently feature simple edge designs, lacking structural reinforcement elements such as ribs or reinforcing layers. During transportation, especially during handling or impacts, these edge components may deform or break due to the lack of structural reinforcement, leading to damage to the suitcase. Under excessive weight or external pressure, the edge components and joints may not be able to effectively withstand external pressure, causing the suitcase to deform. The lack of reinforced structure also makes the connection between the edge components and the zipper system prone to loosening, which can affect the smoothness of opening and closing the suitcase over time.
[0005] Traditional suitcase zipper systems have a relatively simple design, and the connection between the zipper and the edge fitting is usually not reinforced. During prolonged or intensive use, the zipper is prone to detaching from the edge fitting, causing the suitcase to fail to close or open properly. The zipper may also get stuck or damaged during operation. Utility Model Content
[0006] In view of the above deficiencies, the main objective of this utility model is to provide a luggage edge assembly structure that can enhance the structural strength of the luggage and simplify its installation.
[0007] To achieve the aforementioned objective, this utility model provides a luggage edge assembly structure, comprising: a first box body having a first box edge; a second box body having a second box edge corresponding to the first box edge of the first box body; a first edge connector having a first box-joining piece for engaging with the first box edge of the first box body, a first connecting piece connected to the first box-joining piece, a first connecting chain piece connected to the first connecting piece and forming a first box-joining groove with the first box-joining piece, the first box-joining groove accommodating the first box edge of the first box body, a first cover piece connected to the first connecting chain piece and forming a first connecting chain groove therewith, and a first stop block connected to the first connecting piece; and a second edge connector having a second box-joining piece for engaging with the second box edge of the second box body, a second connecting piece connected to the second box-joining piece, a second connecting chain piece connected to the second connecting piece and forming a second box-joining groove with the second box-joining piece, the second box-joining groove accommodating the second box body.

[0062] The applicant hereby clarifies that throughout this specification, including the embodiments described below and the claims, all directional terms are based on the directions shown in the drawings. Secondly, in the embodiments and drawings described below, the same element reference numerals represent the same or similar elements or their structural features.
[0063] Please refer to Figure 1 and Figure 2 The preferred embodiment of the suitcase assembly structure of this utility model includes a first suitcase body 10, a first edge connector 30, a first zipper 50, a second suitcase body 20, a second edge connector 40, a second zipper 60, and two connecting units 70.
[0064] like Figures 2 to 6As shown, the first compartment 10 constitutes the main outer shell of the suitcase and has a first side 11, which is the area connected to the edge fittings and zipper strips. The first side 11 is designed with stable strength, which allows the edge fittings and zipper system to be installed tightly, further improving the structural strength of the entire suitcase.
[0065] like Figures 2 to 6 As shown, the second compartment 20 constitutes another part of the suitcase, and is assembled with the first compartment 10 to form the overall structure of the suitcase. The second compartment 20 has a second side 21, which corresponds to the first side 11 of the first compartment 10.
[0066] like Figures 2 to 6 As shown, the first connecting piece 30 is located at the edge of the first housing 10, and is used to connect the housing and the zipper system, and to provide enhanced structural stability.
[0067] The first connecting piece 30 has a first receiving plate 31, a first connecting piece 32, a first connecting chain piece 33, a first shielding piece 34, and a first stop block 35. The first receiving plate 31 is used to engage with the first box edge 11 of the first box body 10. The first connecting piece 32 is connected to the first receiving plate 31. The first connecting chain piece 33 is connected to the first connecting piece 32. A first receiving groove 3a is formed between the first receiving plate 31 and the first connecting chain piece 33 to accommodate the first box edge 11 of the first box body 10. The first shielding piece 34 is connected to the other end of the first connecting chain piece 33 and forms a first connecting chain groove 3b therewith. The first stop block 35 is connected to the first connecting piece 32.
[0068] The first connecting piece 31, the first connecting piece 32, and the first stop 35 are made of the same material (preferably ABS), and the first chain connecting piece 33 and the first cover piece 34 are made of the same material (preferably TPE). That is, the hardness of the first connecting piece 31, the first connecting piece 32, and the first stop 35 of the first edge-joining component 30 is greater than the hardness of the first chain connecting piece 33 and the first cover piece 34. The use of two different materials for the connecting piece and the chain connecting piece of the first edge-joining component 30 allows for better strength and elasticity when the luggage edge-joining components are joined.
[0069] In this embodiment, the first stop 35 of the first connecting piece 30 forms a first stop top surface 351, which corresponds to the extension area of the thickness of the first connecting piece 31, but this utility model is not limited thereto. In addition, the first stop 35 also forms a weight reduction channel hole.
[0070] The first connecting piece 31 and the first connecting chain piece 33 are used to connect with the first box edge 11 and are the main components connecting the box body and the connecting piece. The structure and material of the first connecting piece 31 should ensure that it can effectively withstand external pressure and maintain the overall stability of the box body. The first cover 34 is connected to the other end of the first connecting chain piece 33, covering the zipper strap to prevent it from being exposed to the external environment, further improving the appearance and safety of the suitcase.
[0071] The synergistic effect of these components makes the joints of the suitcase more stable and enhances the overall structural toughness and impact resistance. To achieve optimal strength and flexibility, the first connecting piece 31 and the first chain piece 33 of the first connecting member 30 use two different materials. This material combination design allows the connecting member to have better adaptability and provides higher abrasion resistance or adaptability to other specific needs in actual use. For example, the first connecting piece 31 can use a harder plastic or metal material to enhance structural stability, while the first chain piece 33 can be made of a more flexible synthetic material to provide better zipper operation performance.
[0072] The first stop 35 of the first connecting piece 30 has a first stop top surface 351 that corresponds to the first connecting piece 31, providing additional support. When the first connecting piece 30 is engaged with the first case 10, the first stop top surface 351 effectively prevents the connecting piece from loosening or shifting, ensuring the stability of the suitcase during opening and closing. This design improves the durability of the structure and reduces the risk of damage due to excessive wear during long-term use.
[0073] like Figures 2 to 6 As shown, the second connecting piece 40 corresponds to the first connecting piece 30 and provides a connection to the second housing 20. The second connecting piece 40 has a second connecting plate 41, a second connecting piece 42, a second connecting chain piece 43, a second shield 44, and a second stop 45. The second connecting plate 41 is used to engage with the second housing edge 21 of the second housing 20. The second connecting piece 42 is connected to the second connecting plate 41. The second connecting chain piece 43 is connected to the second connecting piece 42 and can also be used to engage with the second housing edge 21 of the second housing 20. A second housing groove 4a is formed between the second connecting plate 41 and the second connecting chain piece 43 to accommodate the second housing edge 21 of the second housing 20. The second shield 44 is connected to the other end of the second connecting chain piece 43 and forms a second connecting chain groove 4b therewith. The second stop 45 is connected to the second connecting piece 42.
[0074] The second connecting piece 41, the second connecting piece 42, and the second stop 45 are made of the same material (preferably ABS), while the second connecting chain piece 43 and the second cover piece 44 are made of the same material (preferably TPE). That is, the hardness of the second connecting piece 41, the second connecting piece 42, and the second stop 45 of the second edge fitting 40 is greater than the hardness of the second connecting chain piece 43 and the second cover piece 44. The use of two different materials for the connecting pieces and the connecting chain piece of the second edge fitting 40 allows for better strength and elasticity when the luggage edge fittings are joined. In the future, materials more adaptable to different environments can be selected according to different needs, such as abrasion resistance, to further improve product performance.
[0075] In this embodiment, the second stop 45 of the second connecting member 40 forms a second top surface 451, which corresponds to the extension area of the thickness of the second connecting piece 41, but this is not limited to this embodiment. Furthermore, the second stop 45 also has a weight-reducing channel hole. Additionally, the second stop 45 engages with the first stop 35 of the first connecting member 30.
[0076] like Figures 2 to 6 As shown, the first zipper 50 cooperates with the first connecting piece 30 to help reinforce the joint and realize the function of opening and closing the suitcase. The first zipper 50 has a first chain strap 51 and a first chain tooth 52 connected to the first chain strap 51. The first chain strap 51 is used to cooperate with the first connecting piece 33 of the first connecting piece 30 and corresponds to the first stop 35.
[0077] like Figures 2 to 6 As shown, the second zipper strip 60 corresponds to the second connecting piece 40 and assists in opening and closing the joint between the second housing 20 and the first housing 10. The second zipper strip 60 has a second chain belt 61 and a second chain tooth 62 connected to the second chain belt 61. The second chain belt 61 is used to engage with the second connecting piece 43 of the second connecting piece 40 and corresponds to the second stop 45. The second chain tooth 62 engages with the first chain tooth 52 of the first zipper strip 50. The first zipper strip 50 and the second zipper strip 60 constitute a zipper.
[0078] like Figures 2 to 6 As shown, in this embodiment, the connecting unit 70 is a sewn component, that is, it is sewn together with the first box edge 11 of the first box body 10, the first box piece 31 and the first chain piece 33 of the first edge piece 30, and the first chain strap 51 of the first zipper 50, and sewn together with the second box edge 21 of the second box body 20, the second box piece 41 and the second chain piece 43 of the second edge piece 40, and the second chain strap 61 of the second zipper 60. However, the connecting unit 70 can be a sewn component, a pin component, a riveted component, an adhesive component, or a combination of two or more thereof.
[0079] Through this structure, the edge assembly of the suitcase is more stable and easier to install, achieving the purpose of this utility model. The design of this utility model securely integrates the zipper strip with the edge components, and uses a first stop block 35 and a second stop block 45 to prevent the zipper from falling off during use, ensuring smooth and long-term stable zipper operation. In summary, the edge assembly structure of this utility model cleverly combines strength, elasticity, and convenience, and improves overall durability and operability through material selection and structural innovation. This utility model has significant advantages over known technologies, especially in terms of structural strength, durability, and the stability of the zipper system. Through the dual-material design, structural reinforcement, and stable zipper integration, this utility model significantly improves the overall performance of the suitcase, solves many shortcomings of traditional suitcases, and provides a feasible technical path for future product upgrades.
[0080] Another preferred embodiment of this utility model is as follows: Figures 7 to 11 As shown, the embodiment is largely the same as the one described above, except that: the first connecting piece 30 has a first rib 37 that is bent and connected to the first connecting piece 31, further reinforcing the structure of the first connecting piece 30; the second connecting piece 40 has a second rib 47 that is bent and connected to the second connecting piece 41, further reinforcing the structure of the second connecting piece 40. These ribs can further enhance the structural stability of the connecting pieces, thereby improving the luggage's resistance to compression and deformation, making the luggage more able to withstand external forces during transportation, and improving its durability and damage resistance. This achieves the purpose of this utility model.
[0081] The first and second ribs 37 and 47, which are bent and connected, are added to the first and second joints 30. These ribs effectively enhance the structural stability of the joints and provide additional support. The suitcase is better resistant to compression and deformation during transportation, reducing damage to the suitcase body from external pressure and improving durability and damage resistance. This achieves the intended purpose of the utility model.
[0082] In addition to the embodiments described above, the present invention may also be implemented with the following variations.
[0083] For example, the second housing 20, the second connecting piece 40, and the second zipper strip 60 of this utility model do not necessarily have to be of the same structure as the first housing 10, the first connecting piece 30, and the first zipper strip 50 as described above; different structural combinations are possible. Alternatively, the materials of the connecting piece and the zipper strip can be adjusted to adapt to different usage environments.
[0084] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
[0085] Finally, it must be reiterated that the methods and constituent elements disclosed in the foregoing embodiments of this utility model are merely illustrative examples and are not intended to limit the patent scope of this utility model. Any simple structural modifications or changes made without departing from the spirit of this utility model, or any substitutions with other equivalent elements, should still fall within the scope of the claims of this utility model.
