Abstract
Description
suitcase Technical Field
[0001] This invention relates to a suitcase for storing clothing, travel goods, etc., and in particular a suitcase having multiple openings that can be opened to facilitate the retrieval or placement of items, and which can be easily closed. Background Technology
[0002] Suitcases are a common tool for conveniently storing clothes, personal items, etc. when traveling. A typical known movable suitcase structure consists of a suitcase body and a lid connected to the suitcase body. The suitcase body and lid are opened and closed by a zipper. The suitcase body can also be equipped with a lock (usually a combination lock or "customs lock"). When the zipper completely closes the lid and suitcase body, the zipper pull can be engaged with the lock to lock it. After unlocking, the zipper pull can be disengaged from the lock to open the zipper.
[0003] Traditional suitcases are mostly designed with internal compartments to provide better storage space; some suitcases also have additional external pockets for small items. However, no matter how well-designed the internal compartments are, once the user has already packed their clothes and travel essentials, if they suddenly want to retrieve or add items, they must reopen the suitcase, take out or put in the items, rearrange them again, and then close and lock it. This process is inconvenient, especially when such needs arise during travel. Summary of the Invention
[0004] The purpose of this invention is to provide a suitcase with multiple openings that can be opened, allowing users to conveniently choose to open small or large openings when they want to retrieve items from the suitcase or put additional items into the suitcase, without damaging the already organized arrangement of clothes and items inside the suitcase during use.
[0005] Based on the foregoing objectives, the suitcase provided by the present invention has a main body composed of a first compartment and a second compartment connected to each other. The first compartment and the second compartment are closed or opened via a connecting component. The second compartment is provided with a lock and an opening. One side of the opening is rotatably connected to one side of a flap. The other side of the opening is connected to the other side of the flap by a first zipper and can be closed or opened. The zipper head of the first zipper can be engaged with the lock.
[0006] Preferably, the opening is rectangular with two parallel long sides and two parallel short sides, and one side of the flap is rotatably connected to one of the long sides of the opening.
[0007] In one embodiment of the present invention, the flap may include a first cover and a second cover, with one side of the first cover and one side of the second cover rotatably connected by a connecting portion. When the first zipper closes the corresponding side of the first cover and the opening, and the corresponding side of the second cover and the opening, the first cover and the second cover simultaneously completely close the opening. When the first zipper closes the corresponding side of the first cover and the opening, and the corresponding side of the second cover and the opening is not closed, the second cover can rotate relative to the first cover to open a portion of the opening. When the first zipper does not close either the corresponding side of the first cover and the opening, or the corresponding side of the second cover and the opening, the first cover and the second cover can simultaneously rotate relative to the second housing to open the opening.
[0008] In one embodiment of the present invention, the connecting part may be made of fabric, plastic, rubber or a hinge; or it may be any material capable of securely connecting the first cover and the second cover.
[0009] In one embodiment of the present invention, the area of the first cover is larger than the area of the second cover. Accordingly, the user can choose to open the first cover to open a small opening, or choose to open both the first and second covers simultaneously to open a large opening.
[0010] In one embodiment of the present invention, the connecting component may be a second zipper for connecting the first housing and the second housing.
[0011] In another embodiment of the present invention, the connecting component may include a frame that is respectively disposed in the first housing and the second housing and can be connected to each other; for example, an aluminum frame, etc. Attached Figure Description

[0013] Figure 2 is a perspective view showing the suitcase of the present invention with its lid fully open; and
[0014] Figure 3 shows a perspective view of the suitcase of the present invention with the lid partially open, that is, the first lid closed and the second lid open. Detailed Implementation
[0015] To facilitate understanding of the present invention, it is described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of the invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0017] As shown in Figures 1 to 3, the suitcase provided by the present invention has a body 10 composed of a first compartment 101 and a second compartment 102 connected together. More specifically, both the first compartment 101 and the second compartment 102 are containers for storing clothing or items. One side of each can be connected by a flexible fabric, plastic, rubber material, or hinge to allow relative rotation, so that the first compartment 101 and the second compartment 102 can cover or open each other. The other sides of the first compartment 101 and the second compartment 102 are closed by the operation of the connecting assembly 30. Alternatively, the connecting component 30 may be a second zipper used to connect the first case 101 and the second case 102, or the connecting component may include a frame that is fixedly set on the first case 101 and the second case 102 by rivets and can be connected to each other; such as an aluminum frame, etc.; in addition, the bottom of the first case 101 and the second case 102 are provided with casters 50 to facilitate moving the suitcase; the top and side of the first case 101 are respectively provided with a first handle 1011 and a second handle 1012 to facilitate the user to lift.
[0018] The invention is characterized in that the front of the second housing 102 has an opening 1021, and a flip cover 20 is provided in the opening 1021; specifically, one side of the opening 1021 is rotatably connected to one side of the flip cover 20, and the other sides of the opening 1021 are connected to the other sides of the flip cover 20 by a first zipper 40 so that they can be closed or opened.
[0019] More specifically, the opening 1021 is preferably formed as a rectangle with two parallel long sides and two parallel short sides, and one side of the cover 20 is rotatably connected to one of the long sides of the opening 1021.
[0020] The flip cover 20 can be composed of a plurality of covers. For example, in the embodiment shown in the accompanying drawings, the flip cover 20 may include a first cover 201 and a second cover 202, and the area of the first cover 201 is larger than the area of the second cover 202. One side of the first cover 201 is rotatably connected to one side of the second cover 202 by a connecting part 203, and the other side of the first cover 201 is rotatably connected to one side of the opening 1021. The connecting part 203 may be, for example, a flexible fabric, plastic, rubber material, or a hinge. In other words, the other side of the first cover 201 is rotatably connected to the second box 102, and the other two sides of the first cover 201 and the other three sides of the second cover 202 are connected together by the first zipper 40 to the other sides of the opening 1021 that are not connected to the first cover 201; the first zipper 40 preferably has two zipper heads, namely the first zipper head 401 and the second zipper head 402, so that the first zipper head 401 and the second zipper head 402 can be pulled along the first zipper 40 in opposite or the same direction to quickly open or close the opening 1021.
[0021] As shown in Figure 1, via the aforementioned suitcase structure of the present invention, when the user operates the first zipper 40 to close the corresponding side of the first cover 201 and the opening 1021 and the corresponding side of the second cover 202 and the opening 1021, the first cover 201 and the second cover 202 simultaneously completely close the opening 1021. At this time, the first zipper head 401 and the second zipper head 402 can be fastened into the lock 60 to lock them.
[0022] As shown in Figure 2, when the first box 101 and the second box 102 have been closed, but the user needs to take out a larger item from the main body 10, the first zipper head 401 and the second zipper head 402 can be operated to open one long side and two short sides of the opening 1021. In other words, the first zipper 40 will not close the corresponding side of the first cover 201 and the opening 1021, nor the corresponding side of the second cover 202 and the opening 1021, so that the first cover 201 and the second cover 202 can be rotated relative to the second box 102 at the same time to open the large opening 1021.
[0023] As shown in Figure 3, when the first box 101 and the second box 102 have been closed, but the user only needs to take out a small item from the main body 10, the first zipper head 401 can be operated to open the first zipper 40 of the corresponding side of the second cover 202 and the opening 1021, while the corresponding side of the first cover 201 and the opening 1021 remains closed. At this time, the second cover 202 can be rotated relative to the first cover 201 to open a part of the opening 1021.
[0024] The hinged lid 20 provided in the second compartment 102 of this invention is not limited to only two lids, but can also be provided with more lids. Accordingly, when the user wants to take out items from the suitcase or put extra items into the suitcase, he / she can conveniently choose to open the small opening or the large opening, and the arrangement of clothes and items inside the suitcase will not be damaged during use.
[0025] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
