Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a trolley case. Background Art

[0002] There are many types of backpack trolley cases on the market, but all have their drawbacks. One is the most commonly used structure, a three-layer structure consisting of a case, a trolley, and a backpack. This solution is the most common and the simplest to implement, but the trolley takes up a lot of space and is generally located in the middle of the case's width, making it inefficiently used. The resulting case is relatively thick overall, but the actual usable space is very small. Another option is a detachable backpack structure. This solution has the same case as a regular trolley case, but the detachable backpack structure is inconvenient to store and cannot be instantly switched between backpack and trolley modes. Utility Model Content

[0003] The purpose of the utility model is to provide a trolley case, which not only saves space by arranging a trolley on the side and forming a storage space for the shoulder strap through the trolley, but also realizes the mode switching from the trolley case to the backpack through the cover and the trolley.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.

[0005] A trolley case, comprising:

[0006] Box,

[0007] A pull rod is located on the side of the box, and the pull rod and the bottom of the box form an overhead storage space. The pull rod is raised and lowered along the height direction of the box, so that the storage space tends to expand or shrink;

[0008] The shoulder straps are located in the storage space, and the mask covers the storage space, wherein the shoulder straps are exposed by the mask to form a backpack usage state, or the shoulder straps are hidden by the mask, and the pull rod is raised and lowered to form a trolley case usage state.

[0009] Furthermore, a storage cavity for storing the pull rod is formed on the side of the box body, and the storage cavity is connected to the storage space.

[0010] Furthermore, when the trolley case is in use, the storage cavity is partially opened, so that the pull rod moves up and down along the storage cavity, and the storage space is closed.

[0011] Furthermore, when the backpack is in use, the storage cavity is in a closed state and the storage space is in an open state.

[0012] Furthermore, at least one end of the shoulder strap is assembled on the end of the storage cavity, and the shoulder strap constituting the backpack part is staggered with the pull rod.

[0013] Furthermore, a plurality of independent spaces are formed between the pull rod and the inner side of the storage cavity.

[0014] Furthermore, the mask forms a covering surface on the storage space, and the area of ​​the covering surface is smaller than the area of ​​the storage space.

[0015] Furthermore, an enclosure cavity connected to the cover is provided in the storage space. Under normal circumstances, the pull rod is accommodated in the enclosure cavity, and the enclosure cavity forms a covering surface located at the periphery of the pull rod.

[0016] Furthermore, the shoulder strap includes a wide shoulder strap and a narrow shoulder strap connected to the wide shoulder strap, and the narrow shoulder strap extends out of the enclosure cavity.

[0017] Furthermore, the enclosure cavity is an outer shell located on the periphery of the box and a waterproof cloth covering the outer shell.

[0018] The beneficial effects of the utility model are as follows:

[0019] In the utility model, the trolley case is arranged at the side instead of the middle, thereby reducing the space occupied by the trolley case on the case body. Then, the space formed by the trolley case can be used to accommodate the shoulder straps of the backpack. At this time, the shoulder straps in the accommodated state are at the same horizontal height as the trolley case, so that the space is fully utilized.

[0020] In the utility model, the state conversion between a backpack and a trolley case can be realized by lifting the pull rod to form a trolley case, or opening the cover to expose the shoulder strap, with simple operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0028] Refer to the attached Figure 1-3 As shown, a trolley case in this embodiment includes a box body 1. In order to fully reduce the occupancy of the structure forming the box body, in this embodiment, the trolley 2 is designed on the side of the box body 1. A conventional box includes a box body, and a zipper is provided in the middle of the box body along the width direction of the box body to facilitate opening or closing the box. Then a trolley is provided on one side of the zipper, or a trolley is provided directly on the side of the box body. However, the three sides of the trolley 2 and the bottom of the box body form an overhead storage space on the surface of the box body with a narrow width. At this time, in order to save space, the trolley 2 is provided close to the middle. At this time, the assembly shell for assembling the trolley 2 needs to occupy a certain thickness, and the outer periphery of the trolley 2 is also an assembly shell, which seriously occupies the volume of the box body 1. In addition, the addition of too many assembly shells increases the weight of the entire box body, which is inconvenient to use.

[0029] In this embodiment, the pull rod 2 is arranged on the side of the box body 1, and a storage space 21 is formed between the frame of the pull rod 2 and the body of the box body 1 on the side of the box body 1. In this embodiment, the frame of the pull rod 2 is arranged close to the edge of the box body 1, so that the width of the storage space 21 is increased. For example, the width of the storage space formed by the conventional pull rod 2 is generally 15 cm. In this embodiment, since the frame constituting the pull rod 2 is arranged close to the left and right edges of the box body 1, the width of the storage space 21 can be increased to 30 cm, forming a larger space.

[0030] When in use, the pull rod 2 rises and falls along the height direction of the box body 1, thereby increasing or decreasing the length of the storage space 21, so that the storage space 21 tends to expand or shrink. According to this trend, it can also be judged whether the pull rod box is in use.

[0031] In this embodiment, it also includes a shoulder strap 3 located in the storage space 21, and a mask 4 covering the storage space 21. The mask 4 exposes the shoulder strap 21 to form a backpack usage state, or the mask 4 hides the shoulder strap 21, and the pull rod 2 is raised and lowered to form a trolley case usage state.

[0032] In this embodiment, the use of the cover 4 allows the shoulder strap 3 to be placed within the storage space, with the storage height lower than the height of the storage space, or the shoulder strap 3 and the pull rod 2 to be on the same horizontal line along the outer side. This not only provides space for the shoulder strap, but also does not increase the width of the entire case. In this case, the bottom of the storage space 21 is located within the case and can be separated from the case by a partition. Compared to the existing technology, this arrangement not only reduces the weight of the case, but also allows for multiple usage states, maximizing space utilization.

[0033] Example 1

[0034] In this embodiment, the pull rod 2 is formed on the side of the box body 1 to form a storage space 21 with the same width and length as the box body 1, and then a storage cavity 22 for storing the pull rod 2 is formed on the side of the box body 1. At this time, the storage cavity 22 is connected with the storage space 21, but when the pull rod is stored, the volume of the storage cavity 22 is larger than the volume of the storage space 21. At this time, the storage space includes the storage space located at the top of the pull rod formed by extending from the outside of the box body.

[0035] In this embodiment, the storage cavity 21 can be isolated from the box body by a waterproof cloth, etc., and then a partition or an additional pocket can be formed between the waterproof cloth and the pull rod to form a small storage space. The storage space is staggered with the pull rod, that is, it is set at a position where the waterproof cloth is not in contact with the pull rod, and can be used to place various cards or change, identity cards, etc.

[0036] Refer to the attached Figure 3 As shown, in this embodiment, when the suitcase is in use, the storage cavity 22 is partially open, allowing the pull rod to be raised and lowered along the storage cavity 22, while the cover is closed by a zipper or other means to close the storage space with the intermediate strips. The storage space is in a closed state.

[0037] Refer to the attached Figure 2 As shown, in this embodiment, when the backpack is in use, the storage cavity 22 is closed and the storage space 21 is open. At this time, the shoulder strap is exposed, but the pull rod is well stored, does not affect use, and is more beautiful.

[0038] In this embodiment, in order to extend the service life, the connection between the shoulder strap 3 and the partition of the box body 1 can be wider, and then one end of the shoulder strap 3 is extended into the end of the storage cavity 22. The connection can extend from the end to the position of the pull rod close to the inner side of the storage space 22, so that part of the connection is hidden. At this time, in order to avoid mutual influence with the pull rod 2, the shoulder strap 3 can be staggered with the pull rod 2. The staggering at this time specifically reduces the contact between the shoulder strap and the pull rod. At this time, the shoulder strap can be located in the storage cavity 22, and then the connecting part of the shoulder strap is in the storage cavity 22, or in contact with the pull rod, but the shoulder strap constituting the backpack part is located in the storage space 21, staggered with the pull rod.

[0039] In this embodiment, a plurality of independent spaces 23 are formed between the pull rod 2 and the inner side of the storage cavity 22. In this embodiment, for example, if a waterproof cloth is used as the outer cover of the trolley case, the outer cover located outside the pull rod 2 forms the storage cavity 22. In this case, the pull rod is not completely in contact with the storage cavity 22, and a plurality of independent spaces 23 are formed between them. Small pockets can be sewn into the waterproof cloth at these locations to store small items, making good use of the independent spaces.

[0040] Example 2

[0041] This embodiment primarily describes the cover, etc. The cover 4 forms a covering surface over the storage space 21, and the area of ​​the covering surface is smaller than that of the storage space 21. In this embodiment, the cover 4 is only a portion. Based on Example 1, a portion of the waterproof fabric outside the storage space 21 forms the cover 4, which is connected via a zipper. In this case, the cover 4 is only a portion, and only needs to be sufficient to allow the shoulder strap 3 to be removed.

[0042] Refer to the attached Figure 4 As shown, in this embodiment, the cross-sectional area of ​​the shield 4 is smaller than that of the storage space 21. A retaining cavity 5 connected to the shield 4 is provided within the storage space 21. Under normal circumstances, the pull rod 2 is stored within the retaining cavity 5, and the retaining cavity 5 forms a covering surface located around the outer periphery of the pull rod 2. In this state, the retaining cavity 5 protects the pull rod in its stored state. Furthermore, the retaining cavity 5 is located around the storage cavity 22, providing enclosure and protection thereto.

[0043] In the prior art, the shoulder strap 3 is generally wider at the point of contact with the person, so that the shoulder strap 3 includes a wide shoulder strap 31 and a narrow shoulder strap 32 connected to the wide shoulder strap 31. In this case, since the entire shoulder strap is relatively long, the narrow shoulder strap 32 is extended out of the enclosure cavity 5. In this case, the wide shoulder strap 31 is arranged and stored in the enclosure cavity 5 or partially compressed to prevent it from moving around, while the narrow shoulder strap 32 occupies less space and extends out of the enclosure cavity 5 and can be set in the middle.

[0044] In this embodiment, the enclosure cavity 4 is a shell located at the periphery of the box body 1 and a waterproof cloth covering the shell. The shell at this time has a certain downward pressure, which prevents the wide shoulder straps 31 from running around, while the waterproof cloth achieves good waterproofing.

[0045] In this embodiment, the switch between the storage space 21 and the storage cavity 22 is used to switch between the backpack and the suitcase, achieving a simple structure and convenient operation. At the same time, the space around the handle can be fully utilized to store the shoulder straps and small items. In this embodiment, when the shoulder straps are stored, they do not exceed the height of the handle, forming a flat surface, achieving an aesthetically pleasing effect.
