Description

Technical Field

[0001] This utility model relates to a suitcase, and more particularly to a suitcase with a replaceable inner liner. Background Technology

[0002] A suitcase is a device that helps users organize their belongings. It typically consists of a body and an inner liner. The inner liner is housed within the body and isolates items such as clothes and laptops from the body, preventing direct contact and protecting the items during movement. A drawback of existing suitcases is that the body and liner are in a one-to-one correspondence; that is, the suitcase can only have a fixed type of liner. This prevents the suitcase from meeting the specific needs of users in different application scenarios. For example, in typical application scenarios like travel and business trips, users need to carry different items. Clearly, a fixed type of liner can only meet the storage needs of either travel or business trip scenarios. If a user uses an liner designed for travel to store items for a business trip, the items may be damaged. In some typical examples, the travel liner is not designed to carry a laptop. If a user needs to use the suitcase with the travel liner for business trips, they will have to place the laptop in the travel liner. However, since the travel liner may need to store items such as clothes and toothbrush cases, these items may damage the laptop. Utility Model Content

The term "a" should not be construed as a limitation on the quantity.

[0038] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 9 A preferred embodiment of the present invention will be disclosed and described in the following description of a suitcase with replaceable inner bags, wherein the suitcase includes a suitcase body 10 and at least two different types of inner bags 20, one of which is selectively disposed on the suitcase body 10, so that the suitcase meets the storage needs of different specific application scenarios.

[0039] Specifically, the suitcase body 10 includes a bottom shell 11, a cover shell 12, a telescopic rod 13 and a set of wheels 14, and the suitcase body 10 has a storage cavity 15.

[0040] More specifically, the shape of the bottom shell 11 and the shape of the cover shell 12 are adapted to each other, both being rectangular. One side of the bottom shell 11 and one side of the cover shell 12 are hinged sides, and the other three sides of the bottom shell 11 and the other three sides of the cover shell 12 are separable sides. The hinged sides of the bottom shell 11 and the cover shell 12 are hingedly connected, and the separable sides of the bottom shell 11 and the cover shell 12 are separably connected. When the separable sides of the bottom shell 11 and the cover shell 12 are connected, the luggage body 10 forms the storage cavity 15 between the bottom shell 11 and the cover shell 12. After the separable sides of the bottom shell 11 and the cover shell 12 are separated, the cover shell 12 is allowed to rotate around the hinge position of the hinged sides of the bottom shell 11 and the cover shell 12.

[0041] It is worth mentioning that the connection method between the separable side of the bottom shell 11 and the separable side of the cover shell 12 is not limited in the luggage of this utility model. For example, in the attached... Figures 1 to 9 In this specific example of the suitcase shown, the suitcase includes a zipper 30, which includes a first row of teeth 31, a second row of teeth 32, and a zipper pull 33. The first row of teeth 31 is located on the separable side of the bottom shell 11, the second row of teeth 32 is located on the separable side of the top shell 12, and the zipper pull 33 is located on either the first row of teeth 31 or the second row of teeth 32. The zipper pull 33 is configured to engage or disengage the teeth in the first row of teeth 31 and the teeth in the second row of teeth 32. When the individual chain teeth in the first row of chain teeth 31 and the individual chain teeth in the second row of chain teeth 32 engage with each other, the separable side of the bottom shell 11 and the separable side of the cover shell 12 are reliably connected, so that the luggage body 10 forms the storage cavity 15 between the bottom shell 11 and the cover shell 12. When the individual chain teeth in the first row of chain teeth 31 and the individual chain teeth in the second row of chain teeth 32 separate from each other, the separable side of the bottom shell 11 and the separable side of the cover shell 12 are separated, so that the cover shell 12 is allowed to rotate around the hinge position of the hinge side of the bottom shell 11 and the hinge side of the cover shell 12.

[0042] The telescopic pull rod 13 is disposed on the top of the bottom shell 11. The bottom of the bottom shell 11 and the bottom of the cover shell 12 are respectively provided with wheels 14. After the separable side of the bottom shell 11 and the separable side of the cover shell 12 are connected, the wheels 14 disposed on the bottom of the bottom shell 11 contact the ground. At this time, the user can pull the suitcase by the telescopic pull rod 13. Alternatively, the wheels 14 disposed on the bottom of the bottom shell 11 and the wheels 14 disposed on the cover shell 12 contact the ground. At this time, the user can push the suitcase by the telescopic pull rod 13.

[0043] Once a type of inner sleeve 20 is selected, the inner sleeve 20 can be installed on the bottom shell 11 or the top shell 12, and the inner sleeve 20 is located in the storage cavity 15 of the suitcase body 10. That is, in the attached... Figures 1 to 9 In the suitcase of the present invention shown, without replacing the suitcase body 10, the user can remove the unsuitable inner bag 20 from the bottom shell 11 or the cover shell 12, select the desired type of inner bag 20, and install the inner bag 20 on the bottom shell 11 or the cover shell 12 to meet the storage needs of specific application scenarios.

[0044] It is worth mentioning that the specific type of the inner bag 20 is not limited in the luggage of this utility model. For example, refer to the attached drawing. Figure 3 and Figure 4 One of the inner bags 20 can be a clothing inner bag 20a, which is mainly used for storing clothing. If the user's specific application scenario is a short trip, the user can choose the clothing inner bag 20a and install it on the bottom shell 11 or the cover shell 12. (Refer to the attached document.) Figures 4 to 8 Another inner sleeve 20 can be a computer sleeve 20b, which is not only used for storing clothes, but also for storing tablet-shaped electronic products such as laptops and tablets. If the user's specific application scenario is business travel, the user can choose the computer sleeve 20b and install it on the bottom shell 11 or the cover shell 12. (Refer to the attached document.) Figure 9 Furthermore, the inner bag 20 can be a vacuum-sealed inner bag 20c, which allows for vacuuming. If the user's specific application scenario is long-distance travel, the user can choose the vacuum-sealed inner bag 20c and install it on the bottom shell 11 or the cover shell 12. It is understood that in other examples of the suitcase of this utility model, the inner bag 20 can also be of other types. For example, the inner bag 20 can be designed specifically for storing camera equipment.

[0045] Reference Appendix Figures 2 to 4 The bottom shell 11 has a bottom shell cavity 111, and a selected inner liner 20 is detachably installed on the bottom shell 11. When the inner liner 20 is installed on the bottom shell 11, the inner liner 20 sinks into the bottom shell cavity 111 of the bottom shell 11. The cover shell 12 has a cover shell cavity 121, and another selected inner liner 20 is detachably installed on the cover shell 12. When the inner liner 20 is installed on the cover shell 12, the inner liner 20 sinks into the cover shell cavity 121 of the cover shell 12. In other words, in this specific example of the suitcase of this utility model, the bottom shell 11 and the top shell 12 can each be fitted with an inner liner 20. By allowing the inner liner 20 installed on the bottom shell 11 to sink into the bottom shell cavity 111 of the bottom shell 11 and the inner liner 20 installed on the top shell 12 to sink into the top shell cavity 121, the inner liner 20 can be effectively prevented from affecting the connection between the separable side of the bottom shell 11 and the separable side of the top shell 12, making the suitcase look neat and convenient for users to move and store the suitcase.

[0046] It is understood that the specific type of the inner liner 20 installed in the bottom shell 11 and sunk into the bottom shell cavity 111 of the bottom shell 11 and the specific type of the inner liner 20 installed in the cover shell 12 and sunk into the cover shell cavity 121 of the cover shell 12 can be the same or different, allowing the user to choose according to their needs. For example, refer to the attached... Figure 3 and Figure 4 The inner sleeve 20 installed on the bottom shell 11 and sunk into the bottom shell cavity 111 of the bottom shell 11 is the clothing inner sleeve 20a, and the inner sleeve 20 installed on the cover shell 12 and sunk into the cover shell cavity 121 of the cover shell 12 is the computer inner sleeve 20b.

[0047] In other examples of the suitcase of this invention, the suitcase only allows the inner liner 20 to be installed on the bottom shell 11, and the inner liner 20 is not allowed to be installed on the top shell 12. In other words, in other examples of the suitcase of this invention, the bottom shell 11 of the suitcase body 10 has the bottom shell cavity 111, the top shell 12 is generally flat and does not have the top shell cavity 121, and an inner liner 20 can be installed on the bottom shell 11 and sink into the bottom shell cavity 111 of the bottom shell 11 after being selected.

[0048] In the appendix Figures 1 to 9In this specific example of the suitcase of the present invention shown, after the inner liner 20 is lowered into the bottom shell cavity 111 of the bottom shell 11, the zipper 30 is used to install the inner liner 20 and the bottom shell 11 to prevent the inner liner 20 from deforming within the bottom shell cavity 111 or from becoming misaligned relative to the bottom shell 11. In other words, the inner liner 20 is detachably installed on the bottom shell 11 by means of the zipper 30. Correspondingly, after the inner liner 20 is lowered into the cover cavity 121 of the cover 12, the zipper 30 is used to install the inner liner 20 and the cover 12 to prevent the inner liner 20 from deforming within the cover cavity 121 of the cover 12 or from becoming misaligned relative to the cover 12, especially during the flipping of the cover 12, the zipper 30 can prevent the inner liner 20 from falling off from the cover cavity 121 of the cover 12. In other words, the inner liner 20 is detachably attached to the cover 12 via the zipper 30.

[0049] Specifically, the inner liner 20 includes a bottom wall 21, a top wall 22, and a side peripheral wall 23. The inner liner 20 also includes an inner cavity 24 and an opening 25. The bottom of the side peripheral wall 23 is connected to the bottom wall 21. For example, the bottom of the side peripheral wall 23 and the periphery of the bottom wall 21 can be sewn together to connect the bottom of the side peripheral wall 23 to the bottom wall 21. The top of the side peripheral wall 23 is connected to the top wall 22. For example, the top of the side peripheral wall 23 and the periphery of the top wall 22 can be sewn together. The bottom wall 21, the top wall 22, and the side walls 23 are stitched together to connect the top of the side wall 23 to the top wall 22, so that the bottom wall 21, the top wall 22, and the side walls 23 form the inner cavity 24 of the inner liner 20. The opening 25 of the inner liner 20 is formed in the top wall 22, and the opening 25 of the inner liner 20 can communicate with the inner cavity 24 to allow external items to be placed into the inner cavity 24 through the opening 25 of the inner liner 20 or items in the inner cavity 24 to be removed through the opening 25. The first row of teeth 31 of the zipper 30 is disposed on the bottom shell 11 and surrounds the opening edge of the bottom shell cavity 111 of the bottom shell 11. The second row of teeth 32 is disposed on the top of the side peripheral wall 23 or the top wall 22 of the inner bag 20 and surrounds the top wall 22. When the zipper pull 33 engages the teeth in the first row of teeth 31 and the teeth in the second row of teeth 32, the zipper 30 connects the inner bag 20 and the bottom shell 11 to reliably install the inner bag 20 onto the bottom shell 11. When the zipper pull 33 separates the teeth in the first row of teeth 31 and the teeth in the second row of teeth 32, the inner bag 20 separates from the bottom shell 11 to allow the inner bag 20 to be detached from the bottom shell 11.

[0050] It is understood that the rim of the cover cavity 121 of the cover 12 is provided with the first row of chain teeth 31. When the zipper 33 causes each chain tooth in the first row of chain teeth 31 and each chain tooth in the second row of chain teeth 32 to engage with each other, the zipper 30 connects the inner bag 20 and the cover 12 to reliably install the inner bag 20 onto the cover 12. When the zipper 33 causes each chain tooth in the first row of chain teeth 31 and each chain tooth in the second row of chain teeth 32 to separate with each other, the inner bag 20 and the cover 12 are separated to allow the inner bag 20 to be detached from the cover 12.

[0051] It is worth mentioning that, for the inner bag 20 implemented as the garment inner bag 20a, the fabric of the bottom wall 21, the top wall 22, and the side peripheral walls 23 is not limited, and the connection process between the bottom of the side peripheral wall 23 and the bottom wall 21, and the connection process between the top of the side peripheral wall 23 and the top wall 22, is not limited, as long as the bottom of the side peripheral wall 23 and the bottom wall 21 can be reliably connected, the top of the side peripheral wall 23 and the top wall 22 can be reliably connected, and the bottom wall 21, the top wall 22, and the side peripheral walls 23 can surround to form the inner cavity 24 of the inner bag 20. In this embodiment, refer to the attached... Figure 3 and Figure 4 The top wall 22 further includes a top wall frame 221 and a rectangular small cover 222. The four sides of the top wall frame 221 are connected to the four sides of the side peripheral wall 23 respectively. One side of the small cover 222 is integrally connected to one side of the top wall frame 221. The other three sides of the small cover 222 and the other three sides of the top wall frame 221 are detachably connected by the zipper 30. The top wall frame 221 is used to form the cavity 25 of the inner bag 20, and the small cover 222 is used to close and open the cavity 25.

[0052] For the inner sleeve 20 implemented as the computer inner sleeve 20b, compared with the inner sleeve 20 implemented as the clothing inner sleeve 20a, the inner sleeve 20 implemented as the computer inner sleeve 20b further includes a first interlayer 26 and a second interlayer 27, see attached figure. Figures 6 to 8One side of the first interlayer 26 is flexibly connected to the top of the side wall 23, and one side of the second interlayer 27 is flexibly connected to the other side of the first interlayer 26. The second interlayer 27 can be stacked on top of the first interlayer 26, and both the first interlayer 26 and the second interlayer 27 are located in the inner cavity 24 of the inner bag 20. When the user selects this inner bag 20, clothes can be stored in the space of the inner cavity 24 below the first interlayer 26, and tablet computers, tablets, and other flat electronic products can be clamped between the first interlayer 26 and the second interlayer 27 or between the second interlayer 27 and the top wall 22 to classify and store different types of items.

[0053] For the inner bag 20 implemented as the vacuum-sealed inner bag 20c, compared with the inner bag 20 implemented as the clothing inner bag 20a, the bottom wall 21, top wall 22, and side peripheral walls 23 of the inner bag 20 implemented as the vacuum-sealed inner bag 20c are made of non-breathable fabric. The bottom of the bottom wall 21 and the side peripheral walls 23 are sealed together, for example, the bottom of the bottom wall 21 and the side peripheral walls 23 are connected by a heat-fusion process. The top of the top wall 22 and the side peripheral walls 23 are sealed together, for example, the top of the top wall 22 and the top of the side peripheral walls 23 are connected by a heat-fusion process. The middle of the top wall 22 is slit to form the cavity 25 of the inner bag 20. The top wall 22 is provided with sealing mechanisms such as zippers on opposite sides of the slit to prevent air leakage. At the same time, the inner bag 20 further includes a vacuum one-way valve 28. (Refer to the attached document.) Figure 9 The one-way valve 28 is provided on the top wall 22 to allow the user to extract the air from the inner cavity 24 of the inner liner 20 using an air extraction device.

[0054] Appendix Figure 10 A modified example of the said suitcase is shown, with attached Figures 1 to 9 Unlike the suitcase shown, the attached Figure 10 In this specific example of the suitcase shown, after the inner sleeve 20 is lowered into the bottom shell cavity 111 of the bottom shell 11, the Velcro 40 is used to connect the inner sleeve 20 and the bottom shell 11; after the inner sleeve 20 is lowered into the cover shell cavity 121 of the cover shell 12, the Velcro 40 is used to connect the inner sleeve 20 and the cover shell 12. In other words, the inner sleeve 20 is detachably attached to the bottom shell 11 or the cover shell 12 by means of the Velcro 40.

[0055] Specifically, the Velcro 40 includes a rough surface portion 41 and a hook surface portion 42. The rough surface portion 41 is disposed on the inner wall of the bottom shell 11 that defines the bottom shell cavity 111. For example, the rough surface portion 41 can be sewn to the inner wall of the bottom shell 11, or the rough surface portion 41 can be glued to the inner wall of the bottom shell 11. The hook surface portion 42 is disposed on the side peripheral wall 23 of the inner sleeve 20. For example, the hook surface portion 42 can be sewn to the side peripheral wall 23, or the hook surface portion 42 can be glued to the side peripheral wall 23.
