Description

Technical Field

[0001] The present invention relates to the technical field of luggage cases, and in particular to a multifunctional luggage case which can be used as a table and a chair respectively. Background Art

[0002] Luggage, a must-have item for long-distance travel, is a common sight in everyday life. However, there are often scenarios like this: a traveler, tired after a long journey, lugging their suitcase while waiting for a bus, finds themselves unable to find a suitable place to sit and rest. Or a business person who frequently travels receives a last-minute assignment from their company and finds they have nowhere to put their laptop, forcing them to rest it on their lap. These seemingly trivial matters can significantly impact a customer's travel experience. In light of these situations, a luggage case that provides a platform for passengers to use while traveling or waiting for a bus would undoubtedly be widely popular in the market. The present invention is designed with this goal in mind. Furthermore, this multifunctional luggage case is versatile, durable, economical, and inexpensive to manufacture. The production cost is comparable to that of ordinary luggage, thus offering high economic value. Summary of the Invention

[0003] The object of the present invention is to overcome the deficiencies of the prior art and to provide a multifunctional suitcase which can be used as a table and a chair respectively.

[0004] The technical solution of the present invention is a multifunctional suitcase that can be used as both a table and a chair. The suitcase comprises a body and a tabletop. The body is provided with a reversible frame, and a recess is provided on the surface of the body to accommodate the reversible frame. When the reversible frame is unfolded, the tabletop is mounted on the reversible frame via a fixing device, allowing it to be used as a table. When the reversible frame is folded, it fits into the recess, and the tabletop is detachably connected to the body via the fixing device, allowing it to be used as either a chair or a suitcase. The body has all the functions of a conventional suitcase. When the reversible frame is unfolded, it supports the tabletop. When folded, the reversible frame reinforces the suitcase, sharing pressure with the body, allowing it to be used as a chair.

[0005] The reversible frame includes two symmetrically arranged support frames, each of which includes a first support member, a second support member, and a third support member connected in sequence. The first support member is fixedly connected to the second support member, and the second support member and the third support member are connected by a limit hinge. The second support member is X-shaped, and the angle between the first and second support members is 90 degrees. The X-shaped second support member serves to enhance strength.

[0006] The first support member, the second support member and the third support member are all aluminum tubes with a square cross section, preferably an aluminum tube with a cross section of 20×20 mm.

[0007] The end of the third support member is provided with a magnet, and when the flip frame is folded, the magnets on the third support member attract each other. Wherein, adopting this structure, the third support member is not easy to fall apart, and the table top is also not easy to fall off.

[0008] The groove is provided with a rotation axis fixing hole and a rotation axis, and the first support member is hingedly connected to the rotation axis. With this structure, the reversible frame is fixed to the box body and can rotate 180 degrees. When the first support member is flipped, the second and third support members are also flipped. The second and third support members are unfolded to be on the same plane via the limit hinge. After flipping, the first support member remains in the groove, thus limiting and stabilizing the table top.

[0009] The third support member is also provided with a reinforcing rod. This structure can strengthen the strength of the flip frame and prevent deformation caused by stress.

[0010] The groove includes a first section and a second section, corresponding to the first support member and the second support member, respectively. The first section is located at the back of the box, and the second section is located at the top and bottom of the box. When the reversible frame is folded, the first support member is embedded in the first section of the groove, the second support member is embedded in the second section of the groove, and the third support member is located on the table top placed on the front of the box.

[0011] The fixing device includes a rotary lock arranged on the front side of the box and the end of the third support member. A through hole is provided on the table top at a position corresponding to the rotary lock. When the table top is placed on the box or the flip frame, the through hole passes through the rotary lock and is locked.

[0012] The box is provided with a pull rod and wheels, the pull rod running through the back of the box. When the reversible frame is folded up, it fits against the surface of the box, and the reversible frame, the pull rod and its movable track form a closed loop, thereby increasing the carrying capacity of the box when used as a table and chair.

[0013] This multifunctional suitcase, which can be used as both a table and a chair, can be used as follows: when the user needs to rest while dragging the suitcase, they can simply place the suitcase on the ground and sit on it to rest. When it is needed as a table, the user removes the tabletop, flips the reversible frame 180°, and places the suitcase horizontally, with the rotating lock on the third support member facing vertically upward. The tabletop is then snapped onto the rotating lock and locked to fully secure it, allowing it to be used to place the desired equipment. After use, the tabletop is also removed, and the reversible frame is rotated to secure the tabletop onto the rotating lock on the suitcase body to complete the assembly.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The multifunctional suitcase can be used as a table and a chair respectively, and is provided with a reversible frame for supporting a table top. When the reversible frame and the table top are folded up, the suitcase can be used as an ordinary suitcase or a chair. The multifunctional suitcase is rich in functions, strong and durable, economical and affordable, and has a low manufacturing cost. The production cost is not much different from that of an ordinary suitcase, so it has a high economic value. BRIEF DESCRIPTION OF THE DRAWINGS
