Description

Technical Field

[0001] The disclosure relates to a suitcase, more particularly to a suitcase capable of being easily stored.

Background

[0002] Before long distance travels, travelers are used to putting all the things needed during the journey in a suitcase. Due to the limit of suitcase's capacity, travelers, however, usually can only store the relatively important belongings in the suitcase and the relatively not important belongings can only be left. Travelers need to buy necessities which cannot be stored in the suitcase after arriving the destinations. Therefore, to avoid the waste caused by repeat purchases of the same necessities, travelers are often fond of high capacity suitcases, in order to store plenty of personal belongings in those suitcases.

[0003] Although the high capacity suitcase is able to accommodate more belongings, it may cause storage problems for travelers after their travels. For those families with limited storage spaces, they are particularly troubled by the storage of big suitcases.

[0004] Consequently, in order to store suitcases more conveniently, how to make a suitcase with the feature that the size thereof can be reduced after the travels is a problem to be solved for the designers.

SUMMARY

[0005] The disclosure provides a suitcase for solving the storage problems to users after traveling.

[0006] An embodiment of the disclosure provides a suitcase including a back case component, a front lid component and a ring-shaped gusset component. Two opposite sides of the ring-shaped gusset component are connected to an edge of the back case component and an edge of the front lid component, respectively, to form an accommodating space. The ring-shaped gusset component includes a plurality of first supporting parts and a plurality of second supporting parts. The first supporting parts are disposed on the corners of the back case component, respectively. The second supporting parts are disposed on edges of the back case component, respectively. The ring-shaped gusset component includes a plurality of bending parts. The bending parts are disposed between the first supporting parts and the second supporting parts. The flexible deformation capability of each bending part is greater than the flexible deformation capability of each first supporting part and the flexible deformation capability of each second supporting part, and the bending parts are bendable, allowing the first supporting parts and the second supporting parts to be folded upward or downward on the back case component.

[0007] An embodiment of the disclosure provides a suitcase including a back case component, a front lid component and a ring-shaped gusset component. Two opposite sides of the ring-shaped gusset component are connected to an edge of the back case component and an edge of the front lid component, respectively, to form an accommodating space. The ring-shaped gusset component includes a plurality of bending sections and a plurality of sidewall sections which are connected to each other. The bending sections are disposed on corners of the back case component, respectively. The sidewall sections are disposed on edges of the back case component, respectively. The flexible deformation capability of each bending section is greater than the flexible deformation capability of each sidewall section, and the bending sections are bendable, allowing the sidewall sections to be folded upward or downward on the back case component.

[0008] An embodiment of the disclosure provides a suitcase including a back case component, a front lid component and a ring-shaped gusset component. Two opposite sides of the ring-shaped gusset component are connected to an edge of the back case component and an edge of the front lid component, respectively, to form an accommodating space. The ring-shaped gusset component includes a plurality of first accommodating parts, a plurality of second accommodating parts, a plurality of first reinforcement element and a plurality of second reinforcement elements. The first accommodating parts are disposed on corners of the back case component, respectively. The second accommodating parts are disposed on edges of the back case component, respectively. Each first accommodating part is parted from each second accommodating part. The first enforcement elements are detachably disposed on the first accommodating parts, respectively. The second reinforcement elements are detachably disposed on the second accommodating parts, respectively, to form a plurality of bending parts. The flexible deformation capability of each bending part is greater than the flexible deformation capability of each first accommodating part and the flexible deformation capability of each second accommodating part, and the bending parts are bendable, allowing the second accommodating parts to be folded upward or downward on the back case component.

[0009] An embodiment of the disclosure provides a suitcase including a back case component, a front lid component and a ring-shaped gusset component. Two opposite sides of the ring-shaped gusset component are connected to the back case component and the front lid component, respectively, to form an accommodating space capable of being closed. The ring-shaped gusset component includes a plurality of sidewall parts and a plurality of sidewall parts that are configured for connecting the flexible part. The flexible deformation capability of each flexible part is greater than the flexible deformation capability of each sidewall part. An acute angle is formed between one of the plurality of flexible parts and the ring-shaped gusset component. Each two of the sidewall parts that are adjacent to each other are able to be folded upward or downward on the back case component by the bending of one of the plurality of flexible parts which is connected therebetween.

[0010] According to the suitcase as discussed above, since the ring-shaped gusset component is consisted of the plurality of bending parts and the plurality of supporting parts which have different flexible deformation capabilities, and the bending parts are bendable, thus the user is able to fold the supporting parts downward and stack the supporting parts on the back case component. By doing this, the size of the suitcase after being folded is much smaller than the size of the suitcase before being folded, allowing the user to store the suitcase conveniently.

[0011] In addition, since the ring-shaped gusset component is consisted of the plurality of bending sections and the plurality of sidewall sections with different flexible deformation capabilities, and the bending sections are bendable, thus the user is able to fold the sidewall sections downward and close the sidewall sections relative to the back case component. By doing this, the size of the suitcase after being folded is much smaller than the size of the suitcase before being folded, allowing the user to store the suitcase conveniently.

[0012] Furthermore, as the suitcase disclosed above, since the acute angle is formed between each flexible part and the back case component, the flexible deformation capabilities of the flexible parts are greater than the flexible deformation capabilities of all the sidewall part, and the flexible parts are bendable, thus the two sidewall parts, which are adjacent to each other, are able to be folded upward or downward on the back case component by the bending of the flexible part which is connected therebetween, so that the size of the suitcase after being folded is significantly smaller than the size of the suitcase before being folded, allowing the user to store the suitcase conveniently.

DETAILED DESCRIPTION

[0014] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.

[0015] Please refer to FIG. 1 to FIG. 4. FIG. 1 is a perspective view of a suitcase according to a first embodiment of the disclosure. FIG. 2 is a perspective view of the suitcase of FIG. 1 being opened. FIG. 3 is an enlarged partial cross-section view of a ring-shaped gusset component of FIG. 2. FIG. 4 is an enlarged view of a zipper of FIG. 2.

[0016] In this embodiment, a suitcase 10 includes a back case component 100, a front lid component 200 and a ring-shaped gusset component 300. The back case component 100 and the front lid component 200 are made of relatively harder materials for providing better protection. For example, the back case component 100 and the front lid component 200 are made of plastic plates such as polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate (EVA), polyvinyl chloride (PVC) or acrylonitrile butadiene styrene (ABS) resin, or made of fabrics.

[0017] Two opposite sides of the ring-shaped gusset component 300 are connected to an edge of the back case component 100 and an edge of the front lid component 200, respectively, to form an accommodating space 330. In this embodiment, the ring-shaped gusset component 300 is made of composite materials including, for example, 1268D fabric, PE, PVC, PP, EVA or ABS and relatively softer materials such as cane fabric, butadiene resin (SBR), 150D jersey fabric, polyurethane (PU), rubber, thermoplastic polyurethane (TPU), Sandwich Mesh Fabric, neoprene, polyester, thermoplastic rubbers (TPR), webbing, or leather. In detail, the ring-shaped gusset component 300 has a plurality of sidewall parts 3100 and a plurality of flexible parts 3200, which are configured for connecting the sidewall parts 3100, to form the accommodating space 330.

[0018] Each flexible part 3200 extents along a direction from an edge which the ring-shaped gusset component 300 is connected to the back case component 100 to an edge which the ring-shaped gusset component 300 is connected to the front lid component 200, and an acute angle θ is formed between each flexible part 3200 and the back case component 100. In detail, in this embodiment, the flexible parts 3200 extent from corners of the ring-shaped gusset component 300 ,respectively, to the sidewall parts 3100 which are disposed on the top side and bottom side of the suitcase 10, respectively, to form the acute angles θ, but the disclosure is not limited thereto. For example, in some embodiments, the flexible parts 3200 are able to extent from the corners of the ring-shaped gusset component 300 to the sidewall parts 3100 which are disposed on the right side and left side of the suitcase 10, respectively.

[0019] In this embodiment, a width of each flexible part 3200 continuously decreases from the back case component 100 to the front lid component 200, but the disclosure is not limited thereto. For example, in some embodiments, the width of each flexible part 3200 is constant or gradually increases in a direction away from the back case component 100. The flexible deformation capability of each flexible part 3200 is greater than the flexible deformation capability of each sidewall part 3100, and the flexible parts 3200 are bendable, thus each two of the sidewall parts 3100, which are adjacent to each other, are able to be folded upward or downward on the back case component 100 by the bending of one of the flexible parts 3200 connected therebetween, thereby having a storage position and a use position.

[0020] In detail, in this embodiment, each of the sidewall parts 3100 is, for example, made of a PU 1682D fabric layer 3310, an EVA layer 3320 and a PP plate layer 3330 which are stacked on one another. Each of the flexible parts 3200 is, for example, made of a cane fabric layer 3340, a SBR layer 3350 and a 150D jersey fabric layer 3360 which are stacked on one another. Furthermore, the flexible deformation capabilities of the cane cloth layer 3340, the SBR layer 3350 and the 150D jersey fabric layer 3360 are greater than the flexible deformation capabilities of PU 1682D fabric layer 3310, the EVA layer 3320 and the PP plate layer 3330, and the cane cloth layer 3340, the SBR layer 3350 and the 150D jersey fabric layer 3360 are bendable, thus when the flexible parts 3200 are bent, two sidewall parts 3100, which are adjacent to each other, are able to be folded upward or downward on the back case component 100. The cane cloth layer 840 is, for example, made of SBR. In this embodiment, a thickness of the SBR layer is 3 mm, a thickness of the EVA layer is 1.5 mm, and a thickness of the PP plate layer is 0.8, but the disclosure is not limited thereto.

[0021] In this embodiment, the ring-shaped gusset component 300 has a first opening 340. The front lid component 200 has a second opening 210. One of the sidewall parts 3100 includes a sidewall body 386 and a connecting body 387. The sidewall body 386 has an outer surface 386a and a depression 386b. The depression 386b is located on the outer surface 386a of the sidewall body 386. The connecting body 387 has two opposite edges, one of the edges is connected to an edge of the sidewall body 386 which forms the depression 386b, and the other edge is connected to an edge of the second opening 210 of the front lid component 200. That is to say, the connecting body 387 is connected between the front lid component 200 and the sidewall body 386. In some embodiments, the sidewall body 386 has hollows which are corresponding to the depression 386b.

[0022] The front lid component 200 is connected to the ring-shaped gusset component 300 by a zipper 400, so as to form the accommodating space 330. The zipper 400 includes two chains 410, two zipper heads 420 and two pull tabs 430. One of the chains 410 is disposed around an edge of the first opening 340 and the edge of the depression 386b. The other chain 410 is disposed around the edge of the second opening 210 and the edge of the connecting body 387. The two zipper heads 420 are configured for tying or separating the two chains 410 in order to close or open the suitcase 10, allowing the connecting body 387 to cover or uncover the sidewall body 386. The two pull tabs 430 are movably installed on the zipper heads 420, respectively, and disposed outside of the accommodating space 330. The disclosure is not limited to the quantity of the zipper heads 420. For example, in some embodiments, the quantity of the zipper head 420 is one. The zipper 400 is just one of the connection elements for connecting the front lid component 200 and the ring-shaped gusset component 300, and the aforementioned connection element is, for example, a Velcro or a button.

[0023] In this and some embodiments, the ring-shaped gusset component 300 further includes a fixing belt 3400. The fixing belt 3400 includes a first belt body 3410 and a second belt body 3420. The first belt body 3410 and the second belt body 3420 are disposed on any two opposite sidewall parts 3100, respectively. The first belt body 3410 is detachably connected to the second belt body 3420. In this embodiment, the first belt body 3410 and the second belt body 3420 are disposed on left side sidewall part 3100 and right side sidewall part 3100, respectively, but the disclosure is not limited thereto. For example, in some embodiments, the first belt body 3410 and the second belt body 3420 are able to be disposed on the top side sidewall part 3100 and bottom side sidewall part 3100. Words of orientation, such as right, left, top, bottom, front, rear, etc., as used herein, are based on the position of the wheels. For example, a side where the wheels are disposed is defined as the bottom side.

[0024] In this and some embodiments, the front lid component 200 further includes a belt 395. The belt 395 includes a first belt body 396 and a second belt body 397. The first belt body 396 and the second belt body 397 are disposed on the front lid component 200. The first belt body 396 is detachably connected to the second belt body 397. In addition, the first belt body 396 and the second belt body 397 are disposed on the top side and the bottom side of front lid component 200, but the disclosure is not limited thereto. For example, in some embodiments, the first belt body 396 and the second belt body 397 are disposed on the left side and the right side of the front lid component 200.

[0025] In this and some embodiments, the suitcase 10 further includes two third reinforcement element 3510 disposed on two sidewall parts 3100 which are disposed on the right side and the left side of the suitcase 10, respectively. The disclosure is not limited to the quantity of the third reinforcement element 3510. For example, in some embodiments, the quantity of the third reinforcement element 3510 is three, and the three third reinforcement elements 3510 are disposed on three of the sidewall parts 3100, respectively.

[0026] In this and some embodiments, the suitcase 10 further includes a handle 3610 and a fourth reinforcement element 3620. The handle 3610 and the fourth reinforcement element 3620 are disposed on the same sidewall part 3100. The handle 3610 is disposed on the outer surface of the sidewall part 3100. An orthogonal projection of the fourth reinforcement element 3620 on the sidewall part 3100 at least partially overlaps an orthogonal projection of the handle 3610 on the sidewall part 3100, thereby improving structural strength of the sidewall part 3100.

[0027] In this embodiment, the third reinforcement element 3510 and the fourth reinforcement element 3620 are, for example, honeycomb boards. Each of the honeycomb boards has a thickness of, for example, 6mm.

[0028] In addition, in this and some embodiments, the honeycomb board is able to be disposed on the bottom side sidewall part 3100 for improving the bearing capacity of the suitcase 10.

[0029] The storage process of the suitcase 10 of this embodiment is illustrated hereinafter. Please refer to FIG. 2 and FIG. 5 to FIG. 8, which are schematic views of the storage process of FIG. 2.

[0030] First, as shown in FIG. 2, the ring-shaped gusset component 300 is opened relative to the back case component 100 and therefore to be at the use position, allowing users to store goods in the accommodating space 330. Then, the action of folding the ring-shaped case frame 300 starts. As shown in FIG. 5, the two opposite sidewall parts 3100 are pressed or folded downward to form fold lines 311 on the flexible parts 3200 which are connected between the adjacent sidewall parts 3100, respectively.

[0031] Then, as shown in FIG. 6, the rest two opposite sidewall parts 3100 are pressed or folded downward, and thus all the sidewall parts 3100 are able to be closed relative to the back case component 100 to be at the storage position. More specifically, when the flexible parts 3200 are bent, any two of the adjacent sidewall parts 3100 connected to each flexible part 3200 will be closed relative to the back case component 100 according to the flexible deformation capability of the flexible part 3200, and each sidewall part 3100 will be bent to form bending lines 312. Then, the first belt body 3410 is fixed to the second belt body 3420 for fixing the sidewall parts 3100 to be at the storage position.

[0032] Then, as shown in FIG. 7, the back case component 100 and the stored ring-shaped gusset component 300 are stacked on the front lid component 200. Lastly, as shown in FIG. 8, the first belt body 396 and the second belt body 397 are buckled up to tie the back case component 100 and the front lid component 200 together. Moreover, by comparing FIG. 8 to FIG. 1, it is obvious that the size of the suitcase 10 at the storage position is significantly smaller than the size of the suitcase 10 at the use position.

[0033] Please refer to FIG. 9 to FIG. 12. FIG. 9 is a perspective view of a suitcase according to a second embodiment of the disclosure, FIG. 10 is a perspective view of the suitcase of FIG. 9 being opened, and FIG. 11 is an enlarged view of a zipper of FIG. 10.

[0034] In this embodiment, a suitcase 10 includes a back case component 100, a front lid component 200 and a ring-shaped gusset component 300. The back case component 100 and the front lid component 200 are made of relatively harder materials for providing better protection. For example, the back case component 100 and the front lid component 200 are made of plastic plates such as PE, PP, EVA, PVC or ABS resin, or made of fabrics.

[0035] Two opposite sides of the ring-shaped gusset component 300 are connected to an edge of the back case component 100 and an edge of the front lid component 200, respectively, to form an accommodating space 330. In this embodiment, the ring-shaped gusset component 300 is made of composite materials including, for example, PE, PVC, PP, EVA or ABS and relatively softer materials such as PU, rubber, TPU, Sandwich Mesh Fabric, neoprene, polyester, TPR, webbing, or leather. In detail, the ring-shaped gusset component 300 has a plurality of first supporting parts 380 and a plurality of second supporting parts 385 which are connected to the first supporting parts 380. The first supporting parts 380 are disposed on corner of the back case component 100, respectively, and the second supporting parts 385 are disposed on edges of the back case component 100, respectively.

[0036] The materials inside the first supporting parts 380 and the second supporting parts 385 are, for example, made of iron wire frame, wood plate, plastic plate, iron plate, aluminum plate or magnesium alloy plate.

[0037] The ring-shaped gusset component 300 includes a plurality of bending parts 390. Each bending part 390 is disposed between the first supporting part 380 and the second supporting part 385 which are adjacent to each other and extends from the back case component 100 to the front lid component 200. In other word, two opposite sides of each bending part 390 are connected to first supporting part 380 and the second supporting part 385, respectively. In addition, the flexible deformation capability of each bending part 390 is greater than the flexible deformation capability of each first supporting part 380 and the flexible deformation capability of each second supporting part 385, and the bending parts 390 are bendable, allowing the first supporting parts 380 and the second supporting parts 385 to be closed relative to the back case component 100 to be at a storage position and to be opened relative to the back case component 100 to be at a use position.

[0038] In detail, in this embodiment, each of the first supporting parts 380 is, for example, made of a PVC layer 810, an EVA layer 820, a PP plate layer 830, a sugar cane cloth layer 840, a neoprene layer 850 and a PVC bottom layer 860 which are stacked on one another. Each of the second supporting parts 385 is, for example, made of a PVC layer 810, a EVA layer 820 and a PP plate layer 830 which are stacked on one another. In addition, each bending part 390 is disposed between one of the first supporting parts 380 and one of the second supporting part 385 which are adjacent to each other. Each bending part 390 is, for example, made of a sugar cane cloth layer 840, a neoprene layer 850 and a PVC bottom layer 860. Since the flexible deformation capabilities of the sugar cane cloth layer 840, the neoprene layer 850 and the PVC bottom layer 860 are greater than the flexible deformation capabilities of the PVC layer 810 and the PP plate layer 830, and the sugar cane cloth layer 840, the neoprene layer 850 and the PVC bottom layer 860 are bendable, the first supporting parts 380 and the second supporting parts 385 are able to be folded upward or downward on the back case component 100, thereby having a storage position and a use position. The aforementioned sugar cane cloth layer 840 is made of, for example, SBR. In this and some embodiments, the aforementioned PVC bottom layer 860 is attached with a PVC film. In addition, in this embodiment, the PP plate layer 830 is disposed within the first supporting parts 380 and the second supporting parts 385 by sewing, but the disclosure is not limited thereto. In some embodiments, the PP plate layer 830 is detachably disposed in the first supporting parts 385 and the second supporting parts 390.

[0039] In this embodiment, the ring-shaped gusset component 300 has a first opening 340, and the front lid component 200 has a second opening 210. One of the second supporting parts 385 includes a sidewall body 386 and a connecting body 387. The sidewall body 386 has an outer surface 386a and a depression 386b. The depression 386b is located on the outer surface 386a of the sidewall body 386. The connecting body 387 has two opposite later edges, one of the edges of the connecting body 387 is connected to an edge of the sidewall body 386 which forms the depression 386b. The other edge of the connecting body 387 is connected to an edge of the second opening 210 of the front lid component 200. That is to say, the connecting body 387 is connected between the front lid component 200 and the sidewall body 386.

[0040] In addition, the front lid component 200 is connected to the ring-shaped gusset component 300 by a zipper 400, so as to form the accommodating space 330. The zipper 400 includes two chains 410, two zipper heads 420 and two pull tabs 430. One of the chains 410 is configured for surrounding the edge of the first opening 340 and the edge of the depression 386b. The other chain 410 id configured for surrounding the edge of the second opening 210 and the edge of the connecting body 387. The two zipper heads 420 are configured for tying the two chains 410 to close the suitcase 10 or separating the two chains 410 to open the suitcase 10, allowing the connecting body 387 to cover or away from the sidewall body 386. The two pull tabs 430 are movably installed on the zipper heads 420, respectively, and disposed outside of the accommodating space 330. The disclosure is not limited to the quantity of the zipper head 420. In some embodiments, the quantity of the zipper head 420 is one. The zipper 400 is just one of the connection elements for connecting the front lid component 200 and the ring-shaped gusset component 300, but the disclosure is not limited thereto. In some embodiments, the aforementioned connection element is, for example, a Velcro or a button.

[0041] In this and some embodiments, the ring-shaped gusset component 300 further includes a belt 395. The belt 395 includes a first belt body 396 and a second belt body 397. The first belt body 396 and the second belt body 397 are detachably disposed on the outer surface of the ring-shaped gusset component 300, but the disclosure is not limited thereto. In some embodiments, the first belt body 396 and the second belt body 397 are disposed on an inner surface of the ring-shaped gusset component 300. In yet another embodiment, the first belt body 396 is directly connected to the outer surface of the ring-shaped gusset component 300, that is, the first belt body 396 and the ring-shaped gusset component 300 are not detachable. When the first belt body 396 is connected to the second belt body 397, each first supporting part 380 and each second supporting part 385 are able to be fixed at the storage position. In addition, in this embodiment, the first belt body 396 and the second belt body 397 are disposed on the top side and the bottom side of the ring-shaped gusset component 300, respectively, but the disclosure is not limited thereto. In some embodiments, the first belt body 396 and the second belt body 397 are disposed on the right side and the left side of the ring-shaped gusset component 300, respectively.

[0042] In addition, in this and some embodiments, the suitcase 10 further includes a gripping part 930. The gripping part 930 is connected to the second extending part 230.

However, in some embodiments, the gripping part 930 is connected to the first extending part 398, but the disclosure is not limited thereto.

[0058] The storage process of the suitcase 10 of this embodiment is illustrated hereinafter. Please refer to FIG. 18 and FIG. 21 to FIG. 24. FIG. 21 to FIG. 24 are schematic views of the storage process of FIG. 18.

[0059] First, as shown in FIG. 18, the ring-shaped gusset component 300 is opened relative to the back case component 100 and therefore to be at the use position, allowing the user to store the goods in the accommodating space 330. Then, the action of folding the ring-shaped gusset component 300 starts. As shown in FIG. 21, two of the second supporting parts 385 that are pressed or folded downward to form the fold lines 311.

[0060] Then, as shown in FIG. 22, the rest two opposite second supporting parts 385 are pressed or folded downward, and thus each first supporting part 380 and each second supporting part 385 are stacked on the back case component 100 to be at the storage position. Then, as shown in FIG. 23, the front lid component 200 is stacked on the back case component 100 and the stored ring-shaped gusset component 300. Lastly, as shown in FIG. 24, the first belt body 396 and the second belt body 397 are buckled up to tie the back case component 100 and the front lid component 200 together. Moreover, by comparing FIG. 24 to FIG. 17, it is obvious that the size of the suitcase 10 at the storage position is significantly smaller than the size of the suitcase 10 at the use position.

[0061] In some embodiments, the suitcase 10 is able to have different bending parts. Please refer to FIG. 25 to FIG. 28.. FIG. 26 is a perspective view of a suitcase of FIG. 25 being opened. FIG. 27A is a partial enlarged view of FIG. 26. FIG. 27B is a perspective view of FIG. 27A being bent. FIG. 28 is an enlarged view of the zipper of FIG. 26.

[0062] In this embodiment, the suitcase 10 includes a back case component 100, a front lid component 200 and a ring-shaped gusset component 300. The back case component 100 and the front lid component 200 are made of relatively harder materials for providing better protection. For example, the back case component 100 and the front lid component 200 are made of plastic plates such as polyethylene (PE), polypropylene (PP), EVA, PVC or ABS resin, or made of fabrics.

[0063] Two opposite sides of the ring-shaped gusset component 300 are connected to an edge of the back case component 100 and an edge of the front lid component 200, respectively, to form an accommodating space 330. In this embodiment, the ring-shaped gusset component 300 is made of composite materials, for example, the combination of plastic plates such as PE, PP, EVA or ABS and relatively softer materials such as PU, rubber, TPU, TPR. The ring-shaped gusset component 300 includes a plurality of bending sections 310 and a plurality of sidewall sections 320. The bending sections 310 are disposed on corners of the back case component 100, respectively. The sidewall sections 320 are disposed on edges of the back case component 100, respectively. Since the bending sections 310 are made of relatively softer materials such as PU, rubber, TPU or TPR while the inside of the sidewall sections 320 are made of relatively harder materials, for example, the plastic plate such as PE, PP or ABS, or made of wood plate, iron frame, paper plate, aluminum plate, iron wire frame, iron plate or magnesium alloy plate, and thus the flexible deformation capability of each bending section 310 is greater than the flexible deformation capability of each sidewall section 320. In addition, the bending sections 310 are bendable, thus when the sidewall sections 320 are able to be folded upward or downward on the back case component 100, thereby having a storage position and a use position.

[0064] Specifically, since the bending sections 310 has great flexible deformation capability and is bendable, the user is able to bend the bending sections 310 to change the form of the ring-shaped gusset component 300 for storing the suitcase 10. Since the flexible deformation capability of the sidewall section 320 is less than the flexible deformation capability of the bending section 310, namely the rigidity of the sidewall section 320 is greater than the rigidity of the bending section 310, thus the sidewall sections 320 are able to provide protection and support to the suitcase 10. In addition, for the purpose of opening or closing the sidewall sections 320 relative to the back case component 100 easier, a crease or a material with great flexible deformation capability is disposed between each sidewall section 320 and the back case component 100, allowing each sidewall sections 320 to be folded relative to the back case component 100.

[0065] In addition, as shown in FIG. 27B, the bending sections 310 has at least one fold line 311. The fold line 311 is, for example, handmade or produced by mechanical process such as imprinting in order to facilitate the user to store or use the suitcase 10.

[0066] In this and some embodiments, each bending section 310 and the adjacent sidewall section 320 has a convergence line 360 therebetween. The convergence line 360 is, for example, a curve as shown in FIG. 27A or an arc. In some embodiments, the convergence line 360 is a straight line, thus the two adjacent convergence lines 360 are able to be parallel to each other or not parallel to each other.

[0067] Moreover, in this embodiment, the ring-shaped gusset component 300 has a first opening 340, and the front lid component has a second opening 210. The front lid component 200 is connected to the ring-shaped gusset component 300 by a zipper 400, so as to form the accommodating space 330. The zipper 400 includes two chains 410 and two zipper heads 420. The two chains 410 are disposed around an edge of the first opening 340 and an edge of the second opening 210. The two zipper heads 420 are configured for tying or separating the two chains 410 in order to close or open the suitcase 10. The zipper 400 is just one of the connection elements for connecting the front lid component 200 and the ring-shaped gusset component 300, and the aforementioned connection element is, for example, a Velcro or a button.

[0068] Besides, in some embodiments, the sidewall body 386 and the connecting body 387 as shown in FIG. 1 are able to be applied to the aforementioned sidewall sections 320.

[0069] In this embodiment, the two chains 410 are connected to each other to form a connection section 411. The connection section 411 is disposed between the front lid component 200 and the ring-shaped gusset component 300. In addition, the connection section 411 has a length which allows the front lid component 200 and the ring-shaped gusset component 300 to be maintained at a specific distance when the front lid component 200 and the ring-shaped gusset component 300 are separated from each other. In this embodiment, the length of the connection section 411, namely the distance of the front lid component 200 and the ring-shaped gusset component 300 is, for example, bigger than a width of the ring-shaped gusset component 300. Therefore, the length of the connection section 411 is long enough for users to bend the bending sections 310 for closing all the sidewall sections 320 relative to the back case component 100.

[0070] In this embodiment, the suitcase 10 further includes a plurality of first wheels 600 and a plurality of second wheels 610. The first wheels 600 are disposed on the back case component 100, and the second wheels 610 are disposed on the front lid component 200. However, the positions and quantities of the wheels 600 and 610 are not intended to limit the disclosure.

[0071] In this and some embodiments, the suitcase 10 further includes at least one handle 350. The handle 350 is disposed on the ring-shaped gusset component 300. In addition, in some embodiments, the suitcase 10 are equipped with two handles 350 disposed on two of the sidewall sections 320, respectively, for users to carry the suitcase 10 in different orientations.

[0072] In this and some embodiments, the suitcase 10 further includes a telescoping handle 700. The telescoping handle 700 is disposed on the back case component 100 for transporting the suitcase 10.

[0073] In this and some other embodiments, the back case component 100 includes a belt 110. The belt 110 includes a first belt body 111 and a second belt body 112 which are able to be separated from each other and connected to each other. When the first belt body 111 and the second belt body 112 are connected to each other, the first belt body 111 and the second belt body 112 are able to surround the back case component 100 and the stored ring-shaped gusset component 300, allowing the back case component 100 and ring-shaped gusset component 300 to close to the front lid component 200. However, the belt 110 is not only be used to tight the stored back case component 100 and the ring-shaped gusset component 300, but also be used to constrain goods stored inside the back case component 100 and the ring-shaped gusset component 300. In this and some embodiments, the front lid component 200 includes a belt 220. The belt 220 includes a first belt body 221 and a second belt body 222. The first belt body 221 and the second belt body 222 are disposed on two sides of the front lid component 200 that are opposite to each other, respectively. The first belt body 221 and the second belt body 222 are connected to each other for constraining the goods stored inside the front lid component 200.

[0074] In this and some embodiments, the ring-shaped gusset component 300 further includes two retaining rings 370. The two retaining rings 370 are disposed on two opposite sides of the first opening 340. The first belt body 111 and the second belt body 112 of the belt 110 of the back case component 100 are configured for passing through the two retaining rings 370 and being connected to each other.

[0075] Please refer to FIG. 29, which is a perspective view of a suitcase being opened according to a sixth embodiment of the disclosure. In this embodiment, the suitcase 10 further includes at least one honeycomb board 500. The honeycomb board 500 is fixed to the ring-shaped gusset component 300, and is configured for supporting the ring-shaped gusset component 300. Thereby, the structural strength of the suitcase structure 10 can be enhanced. However, in other embodiments, the honeycomb board 500 may be replaced by other components having stronger structural strength than the ring-shaped gusset component 300, such as an iron wire frame, a wood plate, a plastic plate, an iron plate, an aluminum plate, rubber, or a magnesium alloy plate.

[0076] The storage process of the suitcase 10 of this embodiment is illustrated hereinafter. Please refer to FIG. 25 and FIG. 30 to FIG. 33, which are schematic views of the storage process of FIG. 25.

[0077] First, as shown in FIG. 26, the ring-shaped gusset component 300 is opened relative to the back case component 100 and therefore to be at the use position, allowing the user to store the goods in the accommodating space 330. Then, the action of folding the ring-shaped gusset component 300 starts. As shown in FIG. 14, the opposite sidewall sections 320 are pressed or folded downward to form the fold lines 311. Since the four bending sections 310, which are connected to the two opposite sidewall sections 320, are bendable, thus the two opposite sidewall sections 320 are able to be closed relative to the back case component 100.

[0078] Then, as shown in FIG. 31, the rest two opposite sidewall sections 320 are pressed or folded downward, that is, all of the sidewall sections 320 are stacked on the back case component 100 to be at the storage position. The first belt body 111 and the second belt body 112 of the belt 110 are buckled up. As shown in FIG. 32, the back case component 100 and the stored ring-shaped gusset component 300 are stacked on the front lid component 200. Lastly, as shown in FIG. 33, the first belt body 221 and the second belt body 222 of the belt 220 are buckled up to tie the back case component 100 and the front lid component 200 together. Moreover, by comparing FIG. 33 to FIG. 25, it is obvious that the size of the suitcase 10 at the storage position is significantly smaller than the size of the suitcase 10 at the use position.

[0079] Please refer to FIG. 34, which is a perspective view of a suitcase according to a seventh embodiment of the disclosure.

[0080] In this embodiment, a suitcase 10 includes a back case component 100, a front lid component 200 and a ring-shaped gusset component 300. The back case component 100 and the front lid component 200 are made of relatively harder materials for providing better protection. For example, the back case component 100 and the front lid component 200 are made of plastic plates such as polyethylene (PE), polypropylene (PP), EVA, PVC or ABS resin, or made of fabrics.

[0081] Two opposite sides of the ring-shaped gusset component 300 are connected to the an edge of the back case component 100 and an edge of the front lid component 200, respectively, to form an accommodating space 330. The ring-shaped gusset component 300 has a plurality of first accommodating parts 301, a plurality of second accommodating parts 302, a plurality of first reinforcement elements 910 and a plurality of second reinforcement elements 920. The first accommodating parts 301 are disposed on edges of the back case component 100, respectively. The second accommodating parts 302 are disposed on corners of the back case component 100, respectively. Each first accommodating part 301 and each second accommodating part 302 are spaced apart. The first reinforcement elements 910 are detachably disposed in the first accommodating parts 301, respectively. The second reinforcement elements 920 are detachably disposed in the second accommodating parts 302, respectively, allowing the first accommodating parts 301 and the second accommodating parts 302 together form a plurality of bending parts 303 therebetween. In this embodiment, the first reinforcement elements 910 and the second reinforcement elements 920 are plates which are harder than first accommodating parts 301 and the second accommodating parts 302, but the disclosure is not limited thereto. In some embodiments, the first reinforcement elements 910 and the second reinforcement elements 920 are made of iron wire frame, wood plate, plastic plate, iron plate, aluminum plate, paper plate or magnesium alloy plate. In this embodiment, the ring-shaped gusset component 300 has first accommodating parts 301 and second accommodating parts 302, but the disclosure is not limited thereto. In some embodiments, the ring-shaped gusset component 300 only has the first accommodating parts 301, the first reinforcement elements 910 are detachably disposed in the first accommodating parts 301, and thus a plurality of bending part 303 is formed between the adjacent first accommodating parts 301.

[0082] Since the first reinforcement elements 910 are disposed in the first accommodating parts 301, respectively, and the second reinforcement elements 920 are disposed in the second accommodating parts 302, respectively, thereby increasing hardness of the first accommodating parts 301 and the second accommodating parts 302 and improving the protection of the suitcase 10. Moreover, since the bending parts 303 have no reinforcement elements, the flexible deformation capability of each bending part 303 is greater the flexible deformation capability of each first accommodating part 301 and the flexible deformation capability of each second accommodating part 302. The bending parts 303 are bendable, allowing the second accommodating parts 302 are able to be folded upward or downward on the back case component 100.

[0083] Besides, in some embodiments, the sidewall body 386 and the connecting body 387 as shown in FIG. 1 are able to be applied to the aforementioned first accommodating parts 301.

[0084] According to the suitcase as discussed above, since the ring-shaped gusset component is consisted of the plurality of bending parts and the plurality of supporting parts which have different flexible deformation capabilities, and the bending parts are bendable, thus the user is able to fold the supporting parts downward and stack the supporting parts on the back case component. By doing this, the size of the suitcase after being folded is much smaller than the size of the suitcase before being folded, allowing the user to store the suitcase conveniently.

[0085] Since the ring-shaped gusset component is consisted of the plurality of bending sections and the plurality of sidewall sections which have different flexible deformation capabilities, and the bending sections are bendable, thus the user is able to fold the sidewall sections downward and close the sidewall sections relative to the back case component. By doing this, the size of the suitcase after being folded is much smaller than the size of the suitcase before being folded, allowing the user to store the suitcase conveniently.

[0086] Besides, since the structural strength of the honeycomb board is stronger than that of the ring-shaped gusset component, thereby improving the overall structural strength of the suitcase.

[0087] In addition, the zipper has the connection section, thus the front lid component and the ring-shaped gusset component are able to be maintained at a specific distance when the front lid component and the ring-shaped gusset component are separated from each other so as to ensure that the front lid component does not disturb users to fold the ring-shaped gusset component.

[0088] Moreover, since the connecting body of the ring-shaped gusset component is disposed on or penetrating the depression located on the outer surface of the sidewall body, thus the user is able to pull the pull tab from outside of the suitcase for tying or separating the chains.

[0089] Furthermore, as the suitcase disclosed above, since the acute angle is formed between each flexible part and the back case component, the flexible deformation capabilities of the flexible parts are greater than the flexible deformation capabilities of all the sidewall part, and the flexible parts are bendable, thus the two sidewall parts, which are adjacent to each other, are able to be closed relative to the back case component by the bending of the flexible part which is connected therebetween, so that the size of the suitcase after being folded is significantly smaller than the size of the suitcase before being folded, allowing the user to store the suitcase conveniently.
