Abstract
Description
Technical Field
[0005] ,
[0001] The present invention relates to a front-opening travel bag, and more particularly to a front-opening travel bag in which the front door is difficult to sink into the opening of the housing.
Background Art
[0002] A well-known front-opening travel bag is composed of a housing and a front door. The housing is composed of a first shell and a second shell that fit together. The first shell has an opening. The front door is mounted on the outside of the housing so as to correspond to the opening of the first shell.
[0003] When manufacturing a well-known front-opening travel bag, first, the joint part of the first shell and the front door that are integrated is cut with a cutting knife by press molding of a thermoplastic material, and the first shell and the front door are separated to form an opening in the first shell. When separating the first shell and the front door with a cutting knife, the joint part of the first shell and the front door is cut, and at the same time, a part of the outer peripheral edge of the front door is cut off. Therefore, the size of the front door is smaller than the size of the opening of the first shell. Subsequently, when the front door is attached to the housing, a well-known travel bag is completed, but the front door often sinks into the opening of the first shell of the housing without being able to withstand an external force. On the other hand, devising a front-opening travel bag in which the front door is difficult to sink into the opening of the housing is an unsolved problem in the industry.
Summary of the Invention
Problems to be Solved by the Invention
[0004] In view of the above problems, the main object of the present invention is to provide a front-opening travel bag in which the front door is difficult to sink into the opening of the housing.
Means for Solving the Problems
[0005] To solve the aforementioned problems, the front-opening suitcase comprises a housing, one or more support members, and a front door. The housing has a first side wall, a connecting portion, and an opening. The connecting portion is formed to extend in an annular shape from the first side wall. The opening is formed enclosed from the connecting portion and is arranged to connect the inside and outside of the housing. One or more support members are fixed to the connecting portion of the housing and have contact surfaces. The front door is mounted on the outside of the housing to correspond to the opening of the housing and has an annular projection edge. When the front door withstands an external force, the annular projection edge of the front door contacts the contact surfaces of one or more support members.
[0006] More specifically, in the front-opening travel bag according to this invention, one or more support members are fixed to the connecting part of the housing. When the front door withstands an external force, the annular protruding edge of the front door comes into contact with the contact surface of one or more support members, so the front door is less likely to sink into the opening of the housing.
[0007] In a relatively preferred configuration, the housing's connecting section has four corners and horizontal connecting sections located separately between two of the corners. The support member further has a mounting surface facing the contact surface, a connecting surface connecting the contact surface and the mounting surface, and a recessed groove formed between the contact surface, the mounting surface, and the connecting surface. The recessed groove of the support member is fixed to one horizontal connecting section and two corners of the housing's connecting section by a fitting mechanism.
[0008] In a relatively preferred case, the contact surface of the support member has a first horizontal portion and first arc portions connected to both sides of the two first horizontal portions. The support member is fixed to the horizontal connecting portion of the housing's connecting portion with the first horizontal portions, and to the two corners of the housing's connecting portion with the two first arc portions.
[0009] In a relatively preferable case, the front-opening travel bag according to the present invention further comprises a first sleeve that covers the connecting portion of the housing. The concave groove of the support member is fixed to the first sleeve by a fitting method and is indirectly fixed to one horizontal connecting portion and two corners of the connecting portion of the housing via the first sleeve.
[0010] In a relatively preferred case, the contact surface of the support member has a first horizontal portion and first arc portions connected to both sides of the two first horizontal portions. The first horizontal portions are indirectly fixed to the horizontal connecting portion of the housing's connecting portion by a first sleeve. The two first arc portions are indirectly fixed to the two corners of the housing's connecting portion by the first sleeve.
[0011] In relatively preferable cases, the support member further has convex ribs. The convex ribs are formed at the connection point between the contact surface and the connecting surface and extend outward in the direction opposite to the concave groove. Due to the structural features described above, when the front door withstands external force, the annular protruding edge of the front door contacts the convex ribs of one or more support members, making it less likely for the front door to sink into the opening of the housing.
[0012] In relatively preferable cases, a front-opening travel bag comprises multiple support members. The connecting section of the housing has four corners. Each support member further has a mounting surface facing the contact surface, a connecting surface connecting the contact surface and the mounting surface, and a recessed groove formed between the contact surface, the mounting surface and the connecting surface. The recessed groove of each support member is fixed to the corner of the connecting section of the housing by a fitting mechanism.
[0013] Each support member further has convex ribs. The convex ribs are formed at the connection point between the contact surface and the connecting surface and extend outward in the direction opposite to the concave groove. Due to the structural features described above, when the front door withstands external force, the annular protruding edge of the front door contacts the convex ribs of the multiple support members, making it difficult for the front door to sink into the opening of the housing.
[0014] In relatively favorable cases, the contact and mounting surfaces of each support member are arc-shaped, which not only prevents damage to the support member but also improves safety during use.
[0015] In relatively preferable cases, the front-opening travel bag according to the present invention further comprises a first sleeve that covers the connecting portion of the housing. The concave grooves of the multiple support members are indirectly fixed to the corners of the connecting portion of the housing by fitting into the first sleeve.
[0016] The detailed structure, features, assembly, and method of use of the front-opening travel bag 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 cannot limit the scope of the claims of this invention.

Mode for Carrying Out the Invention
[0018] Hereinafter, the front-opening 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.
[0019] (One Embodiment) As shown in FIGS. 1 and 2, the front-opening travel bag 1 according to an embodiment of the present invention includes a housing 10, a plurality of support members 40, a front door 50, and a fastener 70.
[0020] As shown in FIGS. 1 and 2, the housing 10 is composed of a first shell 11 and a second shell 20 that are fitted to each other. The first shell 11 has a first annular wall surface 12, a first side wall 13, a connecting portion 14, and an opening 16. The first side wall 13 is annularly connected to the first annular wall surface 12. The connecting portion 14 is formed to extend annularly on the first side wall 13. The opening 16 is formed to be surrounded by the connecting portion 14. The connecting portion 14 extends horizontally toward the opening 16 and has four corners 15 and a horizontal connecting portion 151 that is separately located between two of the corners 15. The second shell 20 has a second annular wall surface 21 and a second side wall 22. The second annular wall surface 21 faces the first annular wall surface 12. The second side wall 22 is annularly connected to the first annular wall surface 12. The first annular wall surface 12, the first side wall 13, the second annular wall surface 21, and the second side wall 22 constitute a storage space 23 for storing luggage. The opening 16 of the first shell 11 communicates the storage space 23 inside the housing 10 and the outside of the housing 10. The second shell 20 has an elastic carrying bar 24. The housing 10 has four casters 25 at the bottom and is supported by the four casters 25.
[0021] As shown in Figures 1 and 2, the front-opening travel bag 1 further includes a first sleeve 30. The first sleeve 30 is an annular thin piece that covers the connecting portion 14 of the housing 10 and improves the airtightness between the first shell 11 and the front door 50. Since the first sleeve 30 has a waterproof function, it prevents water from seeping into the housing 10 through the gap in the first shell 11 and soiling the contents inside the housing 10.
[0022] As shown in Figure 2, in this embodiment there are two support members 40, but depending on the size of the housing 10 and the user's needs, the number may be increased to three or four. As shown in Figures 3 and 4, each support member 40 has a contact surface 41, a mounting surface 42 spaced apart toward the contact surface 41, a connecting surface 44 connecting the contact surface 41 and the mounting surface 42, and a recessed groove 45 formed between the contact surface 41, the mounting surface 42, and the connecting surface 44. More specifically, the contact surface 41 and the mounting surface 42 are quadrants. The size of the mounting surface 42 is larger than the size of the contact surface 41. Due to the structural features of the contact surface 41 and the mounting surface 42, not only is the support member 40 less susceptible to damage, but safety during use can also be improved. Each support member 40 further has a convex rib 47. The convex rib 47 is formed at the connection point between the contact surface 41 and the connecting surface 44 and extends outward along the direction opposite to the recessed groove 45, as shown in Figure 6.
[0023] As shown in Figures 5 and 6, during assembly, each support member 40 has its contact surface 41 facing the outside of the housing 10 and its mounting surface 42 facing the inside of the housing 10. The concave grooves 45 of each support member 40 are fixed to the first sleeve 30 by a fitting method, and are indirectly fixed to the corners 15 of the connecting portion 14 of the housing 10 via the first sleeve 30. More specifically, by fitting the concave grooves 45 of each support member 40 with the first sleeve 30 located at the corners 15 of the connecting portion 14 of the housing 10, and then injecting adhesive into the concave grooves 45 of each support member 40, each support member 40 can be indirectly fixed to the corners 15 of the connecting portion 14 of the housing 10 via the first sleeve 30. The present invention is not limited to the above, and a method may be adopted in which the first sleeve 30 is not placed in the front-opening travel bag 1, and the concave grooves 45 of each support member 40 are fitted and fixed to the corners 15 of the connecting portion 14 of the housing 10. The method of fixing each support member 40 to each corner 15 of the housing 10 is not limited to this embodiment, and fastening methods such as buttons or screws, or other fixing methods may be employed.
[0024] As shown in Figures 1 and 7, the front door 50 has a surface plate 51 and an annular protruding edge portion 53. The surface plate 51 has four corners 52. The annular protruding edge portion 53 is annularly connected to the surface plate 51 and then fits into the second sleeve 60. The front door 50 is mounted on the outside of the housing 10 so as to correspond to the opening 16 of the housing 10.
[0025] As shown in Figures 1, 2, and 7, the fastener 70 has a first tooth member 71, a second tooth member 75, and two sliders 78. The first tooth member 71 has a first tooth 72 and a first fixing part 73. The first tooth 72 is fixed to the first fixing part 73. The first fixing part 73 is joined to the first sleeve 30 by a suturing method and then indirectly fixed to the connecting part 14 of the housing 10. This embodiment is not limited to the above, and a method may be adopted in which the first sleeve 30 is not placed in the front-opening travel bag 1, and the first fixing part 73 of the first tooth member 71 is directly fixed to the connecting part 14 of the housing 10 by a suturing method. The second tooth member 75 has a second tooth 76 and a second fixing part 77. The second tooth 76 is fixed to the second fixing part 77 and engages with and disengages from the first tooth 72 by the slider 78. The second fixing portion 77 and the second sleeve 60 are joined together by a stitching method and connected to the annular protruding edge portion 53 of the front door 50.
[0026] The above describes the structural features of the front-opening travel bag 1 according to the present invention. Next, we will explain how to use the front-opening travel bag 1 and the effects achieved.
[0027] When using the front-opening travel bag 1, as shown in Figures 1 and 7, the slider 78 interlocks the first teeth 72 and the second teeth 76 to join the front door 50 and the first shell 11 of the housing 10. As shown in Figure 8, when the front door 50 is moved toward the opening 16 of the housing 10 while the surface plate 51 of the front door 50 withstands a lateral external force, the annular protruding edge 53 of the front door 50 and the second sleeve 60 come into contact with the contact surfaces 41 of the multiple support members 40, making it difficult for the front door 50 to sink into the opening 16 of the housing 10. Also, when the front door 50 is moved toward the opening 16 of the housing 10 while the surface plate 51 of the front door 50 withstands an oblique or vertical external force from above, the annular protruding edge 53 of the front door 50 and the second sleeve 60 come into contact with the convex ribs 47 of the multiple support members 40, making it difficult for the front door 50 to sink into the opening 16 of the housing 10.
[0028] The support member 40 is not limited to this embodiment. As shown in Figures 8 and 9, the present invention gives the example of using a different support member 80 in a front-opening travel bag 1. The support member 80 has a contact surface 81, a mounting surface 82 opposite to the contact surface 81, a connecting surface 83 connecting the contact surface 81 and the mounting surface 82, a recessed groove 84 formed between the contact surface 81, the mounting surface 82 and the connecting surface 83, and a convex rib 85. The convex rib 85 is formed at the connection portion between the contact surface 81 and the connecting surface 83 and extends outward along the direction opposite to the recessed groove 84. More specifically, the contact surface 81 has a first horizontal portion 811 and a first arc portion 812 connected to both sides of the two first horizontal portions 811. The mounting surface 82 has a second horizontal portion 821 and a first arc portion 812 connected to both sides of the two second horizontal portions 821. The structural features of the first arc portion 812 of the contact surface 81 and the second arc portion 822 of the mounting surface 82 not only make the support member 80 less susceptible to damage, but also improve safety during use.
[0029] During assembly, the concave groove 84 of the support member 80 is fixed to the first sleeve 30 by a fitting method, and is indirectly fixed to one horizontal connecting portion 151 and two corners 152 of the connecting portion 14 of the housing 10 via the first sleeve 30. In other words, the first horizontal portion 811 of the contact surface 81 of the support member 80 is indirectly fixed to the horizontal connecting portion 151 of the connecting portion 14 of the housing 10 by the first sleeve 30. The two first arc portions 812 of the contact surface 81 of the support member 80 are indirectly fixed to the two corners 15 of the connecting portion 14 of the housing 10 by the first sleeve 30. The present invention is not limited to the above, and a method may be adopted in which the first sleeve 30 is not placed in the front-opening travel bag 1, and the concave groove 84 of each support member 80 is fitted and fixed to one horizontal connecting portion 151 and two corners 15 of the connecting portion 14 of the housing 10. The method of fixing the connecting portion 14 between the support member 80 and the housing 10 is the same as the method of fixing the connecting portion 14 between the support member 40 and the housing 10. The method of directly or indirectly fixing the connecting portion 14 between the support member 80 and the housing 10 is not limited to this embodiment, and may be fastened by buttons, screws, or other fixing methods. Since the effects achieved by the support member 80 and the support member 40 are the same, their description is omitted.
[0030] To summarize the above, in the front-opening travel bag 1 according to the present invention, the support members 40 and 80 are fixed to the connecting portion 14 of the housing 10. When the front door 50 withstands external force, the annular protruding edge portion 53 of the front door 50 comes into contact with the contact surfaces 41 and 81 or the convex ribs 47 and 85 of the respective support members 40 and 80, so that the front door 50 is less likely to sink into the opening 16 of the housing 10.
[0031] 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]
