Description

Technical Field

[0001] The present invention relates to a travel bag, and more particularly to a multi-layer front-opening travel bag that improves the problems of the prior art in which the opening and closing of the travel bag is inconvenient and the sealing is insufficient.

Background Art

[0002] Commercially available travel bags that employ a single opening and closing part have a simple structure, but lack tightness during use. Therefore, there are drawbacks such as foreign objects entering the travel bag and the inability to smoothly open and close, which not only affect the durability and safety of the travel bag. Some travel bags adopt a multi-layer opening and closing design, but lack effective connectivity, so the overall structure is unstable. When taking out luggage, the travel bag must be completely opened, which not only reduces the efficiency and flexibility during use, but also does not conform to modern usage habits. In addition, the design that prioritizes the protection of stored items sacrifices the convenience and smooth appearance during opening and closing, has a complex structure, high cost, poor appearance, and high manufacturing difficulty, so it cannot be accepted by consumers.

[0003] Therefore, it is an object of the present invention to create a travel bag that can achieve convenience, tightness, and stability of the overall structure during opening and closing, improve the function of quickly taking out small items at the same time, and maintain the beauty and comfort of the appearance through a multi-layer tight structure.

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 multi-layer front-opening travel bag that can improve the convenience and tightness during opening and closing and enhance the safety and protection effect during use by means of a multi-stage opening and closing and connecting structure.

Means for Solving the Problems

[0005] To solve the aforementioned problems, the multi-layered front-opening suitcase comprises a first shell, a second shell, a front door, and a pocket door. The first shell has a shell body and a first opening / closing section. The first opening / closing section is connected to the shell body. The second shell has a shell body, a second opening / closing section, and a third opening / closing section. The second opening / closing section is connected to the shell body of the first shell and is closably fitted to the first opening / closing section of the first shell. The third opening / closing section is connected to the shell body of the second shell so as to be located on the opposite side of the second opening / closing section. The front door has a door body, a fourth opening / closing section, and a fifth opening / closing section. The fourth opening / closing section is connected to the door body and is closably fitted to the third opening / closing section of the second shell. The fifth opening / closing section is located on the opposite side of the fourth opening / closing section and is smaller than the fourth opening / closing section. The pocket door has a door body and a sixth opening / closing section. The sixth opening / closing section is connected to the door body and is closably fitted to the fifth opening / closing section of the front door.

[0006] More specifically, by connecting the first opening / closing section of the first shell with the second opening / closing section of the second shell, connecting the third opening / closing section of the second shell with the fourth opening / closing section of the front door, and connecting the fifth opening / closing section of the front door with the sixth opening / closing section of the pocket door, the multi-layered front-opening suitcase can improve convenience and tightness when opening and closing, and enhance structural stability and safety during use.

[0007] In relatively favorable cases, the fifth opening / closing section of the front door is located in the upper half of the front door body. The structural features described above allow for a proper connection between the pocket door and the front door, improving flexibility during opening and closing and convenience during use.

[0008] In relatively preferable cases, the front door has an upper edge support portion. The pocket door has an upper contact edge portion. When the pocket door is opened, the upper contact edge portion contacts the upper edge support portion of the front door. Due to the structural features described above, the opening angle of the pocket door can be stabilized, preventing it from closing suddenly and increasing safety during use.

[0009] In relatively preferable cases, the upper edge support portion of the front door is a concave groove. The aforementioned structural features enhance the support effect, evenly distribute the external forces withheld by the door body, and maintain durability and ease of use.

[0010] In relatively favorable cases, the depth of the pocket door is shallower than the depth of the front door. The aforementioned structural features allow for quick opening and closing of luggage, enabling easy loading and unloading of belongings.

[0011] In a relatively favorable case, the third opening / closing section of the second shell consists of a connected third lower opening / closing section and a third upper opening / closing section. The fourth opening / closing section of the front door consists of a connected fourth lower opening / closing section and a fourth upper opening / closing section. The upper ends of the third lower opening / closing section and the fourth lower opening / closing section are closer to the second opening / closing section than their lower ends. The upper ends of the third lower opening / closing section and the fourth lower opening / closing section meet. Due to the structural features described above, closing the front door improves the automatic alignment and tightness between the front door and the second shell through a guide effect that causes them to converge inward, suppresses displacement during opening and closing, and enhances the overall stability of the structure.

[0012] In relatively preferable cases, the third lower opening section of the third opening part of the second shell and the fourth lower opening section of the fourth opening part of the front door are arc-shaped or sloped. The above-described structural features improve the smoothness of movement during the opening and closing process of the front door, reduce obstruction and wear of the edges, and improve the ease of use during opening and closing as well as the durability of the structure.

[0013] In relatively preferable cases, the front door has a top surface. The top surface is positioned to protrude from the fifth opening / closing section of the front door. Due to the structural features described above, when a suitcase is placed vertically, direct pressure on the fifth opening / closing section is prevented, improving the protective effect of the front-opening structure and maintaining the shape and aesthetic appearance.

[0014] In a relatively favorable case, the shell body of the second shell has a lower edge support. The door body of the front door has a lower contact edge corresponding to the lower edge support. When the front door is opened, the lower contact edge contacts the lower edge support of the second shell. Due to the structural features described above, the front door can be supported, the opening angle of the front door can be controlled, the front door can not be opened too far, and safety during use and structural stability can be improved.

[0015] In relatively preferable cases, the pocket door has a perforation formed in the door body and a hole cover that covers the perforation. The perforation and hole cover allow locks, straps, or identification accessories to be attached to the travel bag. When the travel bag is not in use, the perforation can be sealed with the hole cover to maintain its appearance and prevent foreign objects from entering.

[0016] The detailed structure, features, assembly, and method of use of the multi-layered 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.

Best Mode for Carrying Out the Invention

[0018] Hereinafter, the multi-layer front-opening travel bag according to the present invention will be described based on the drawings.

[0019] In this specification and the drawings, nouns indicating directions 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 to 5, the multi-layer front-opening travel bag 1 according to one embodiment of the present invention includes a first shell 10, a second shell 20, a front door 30, and a pocket door 40.

[0021] The first shell 10 has a shell main body 11 and a first opening / closing part 12. The shell main body 11 is a main shell main body having a storage space. The first opening / closing part 12 is connected to the shell main body 11. By being connected to the second shell 20 in an openable / closable manner, the first opening / closing part 12 opens and closes the space between the first shell 10 and the second shell 20, so that the storage capacity of the entire travel bag can be increased, and the flexibility of the module design can be improved.

[0022] The second shell 20 has a shell main body 21, a second opening / closing part 22, and a third opening / closing part 23. Both sides of the shell main body 21 of the second shell 20 are connected to the second opening / closing part 22 and the third opening / closing part 23. The second opening / closing part 22 is openably mated with the first opening / closing part 12 of the first shell 10. The third opening / closing part 23 is provided on the opposite side of the second opening / closing part 22 and forms an opening that joins with the front door 30.

[0023] The shell main body 21 of the second shell 20 has a lower edge support part 211. The third opening / closing part 23 of the second shell 20 is composed of a continuous third lower opening / closing part 231 and a third upper opening / closing part 232.

[0024] The front door 30 has a door body 31, a fourth opening / closing part 32, and a fifth opening / closing part 33. The door body 31 is connected to the fourth opening / closing part 32 and the fifth opening / closing part 33 on both sides. The fourth opening / closing part 32 is openably fitted to the third opening / closing part 23 of the second shell 20. The fifth opening / closing part 33 is installed on the upper half of one side opposite to the fourth opening / closing part 32 and serves as an interface for connecting the pocket door 40. The door body 31 has an upper edge support part 312 formed at the lower edge part of the fifth opening / closing part 33. The upper edge support part 312 supports the opened pocket door 40. In this embodiment, the upper edge support part 312 is an arc-shaped concave groove, but it is not limited to this.

[0025] The door body 31 of the front door 30 has a lower contact edge part 311 that contacts the lower edge support part 211 when it is open. That is, when the front door 30 is open, the lower contact edge part 311 contacts the lower edge support part 211, so that the front door 30 can be supported, and at the same time, the opening angle can be controlled, improving the stability during opening and closing and the safety during use.

[0026] The fourth opening / closing part 32 of the front door 30 is composed of a continuous fourth lower opening / closing part 321 and a fourth upper opening / closing part 322. The upper ends of the third lower opening / closing part 231 and the fourth lower opening / closing part 321 are closer to the second opening / closing part 22 than their lower ends. That is, since the upper ends of the third lower opening / closing part 231 and the fourth lower opening / closing part 321 are joined and arranged close to the second opening / closing part 22, when the front door 30 is closed, the front door 30 can be made to adhere closely to the shell body 21 of the second shell 20 by the guiding effect of converging inward, improving the tightness between the third opening / closing part 23 and the fourth opening / closing part 32, and suppressing the displacement during opening and closing.

[0027] The third lower opening / closing part 231 of the third opening / closing part 23 of the second shell 20 and the fourth lower opening / closing part 321 of the fourth opening / closing part 32 of the front door 30 are arc-shaped or inclined planes. When the front door 30 and the second shell 20 are relatively opened and closed, the arc-shaped or inclined third lower opening / closing part 231 and fourth lower opening / closing part 321 improve the smoothness of the movement, reduce the interference and wear of the edge parts, and improve the smoothness and durability of the fourth opening / closing part 32 during opening and closing.

[0028] The front door 30 has a top surface 34. The top surface 34 is positioned to protrude from the fifth opening / closing section 33 of the front door 30. When the multi-layer front-opening travel door 1 is placed vertically or compressed by an external force, the above-described structural features prevent direct pressure on the fifth opening / closing section 33, protect the opening and closing function of the sixth opening / closing section 42 of the pocket door 40, and maintain its external shape.

[0029] The pocket door 40 is positioned in the area corresponding to the front door 30 and has a door body 41 and a sixth opening / closing section 42. The sixth opening / closing section 42 opens and closes in conjunction with the fifth opening / closing section 33 of the front door 30, providing a function to quickly open and close a small section, making it easy to put in and take out everyday items such as passports, mobile batteries, and keychains. The door body 41 of the pocket door 40 has an upper contact edge 411. When the pocket door 40 is opened, the upper contact edge 411 contacts the upper edge support section 312 of the front door 30, maintaining the opened pocket door 40 at a predetermined angle. In this embodiment, since the depth of the pocket door 40 is shallower than the depth of the front door 30, it can provide a function to quickly open and close the suitcase and put in and take out luggage.

[0030] The pocket door 40 has a perforation 412 formed in the door body 41 and a hole cover 43 that covers the perforation 412. Objects can be attached to or secured by the combination of the perforation 412 and the hole cover 43. When the perforation 412 does not need to be used, the hole cover 43 can be used to seal the perforation 412, maintaining the appearance and preventing the entry of foreign objects.

[0031] To summarize the above, the first shell 10 and the second shell 20 are positioned in the first open / closed position. The second shell 20 and the front door 30 are positioned in the second open / closed position. The front door 3 and the pocket door 40 are positioned in the third open / closed position. This invention provides the function of quickly opening and closing the suitcase with the pocket door 40, the function of protecting the next layer and covering the entire suitcase with the front door 30, and the storage of the main luggage with the first shell 10. In other words, this invention achieves multiple objectives such as modularity, multi-layer management, and ease of use, while simultaneously improving convenience during opening and closing, flexibility during use, and structural durability.

[0032] 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]
