Abstract
Description
Technical Field
[0001] This invention belongs to the field of seating technology, and particularly relates to a portable seat with loading function. Background Technology
[0002] Seating is an essential household item, facilitating people's lives and work. To improve comfort and functionality, various improvements have been made to seating to meet different needs, including airport seats, car seats, bus seats, family seats, restaurant seats, child safety seats, lounge chairs, and the increasingly popular massage chairs. However, most existing seats are not foldable, resulting in a large footprint and inconvenience in transport. Therefore, foldable seats, such as recliners and outdoor chairs, have been designed; they can be folded but lack cargo capacity.
[0003] To further address the issues of convenient stacking, transportation, and internal storage of chairs, those skilled in the art have conducted numerous studies. For example, patent CN 218551830 U discloses a stackable armchair, including a seat, backrest, support frame, and seat flipping control device. The seat flipping control device includes a rotating mechanism connected between the support frame and the seat, and a stop mechanism located inside the seat and beside the rotating mechanism. This armchair allows for seat flipping and / or armrest folding, enabling the stacking of multiple armchairs for easy storage and transportation. Patent CN 217429575 U discloses a portable chair, including a seat, a foldable backrest, foldable legs, foldable armrests on both sides, and small tables on the armrests. The top of the foldable legs is hinged to a leg storage slot installed under the seat. When folded, the foldable legs enter the leg storage slot; when unfolded, they are fixed in place by threaded sleeves on the legs and threaded fixing holes in the leg storage slots. This design allows for the folding of chair legs and armrests, resulting in a neat and organized chair that makes full use of space and facilitates storage and transportation.
[0004] However, none of the above-mentioned seats can store or carry items within the internal space of the frame, failing to fully solve the problem of seats being foldable, easy to move, and capable of loading, thus limiting the seats' functionality. Summary of the Invention
[0005] To address the limitations of existing seating technologies in meeting the requirements for folding, easy mobility, and loading capabilities, this invention provides a portable seat with loading functionality. This seat can not only be fully folded and moved, but its internal space after folding can also accommodate heavier items, further expanding its functionality.

[0010] Preferably, the bottom end of the support leg 4 has an anti-slip feature.
[0011] Preferably, the bottom surface of the lower frame 202 is provided with a storage groove 7, corresponding to the position of the support leg 1, and the support leg 1 can be folded and placed inside the storage groove 7.
[0012] Preferably, the side length of the upper frame 201 of the support frame 2 is less than or equal to the side length of the lower frame 202.
[0013] Preferably, the upper end of the inclined column 203 is connected to the four corners of the upper frame 201, and the lower end of the inclined column 203 is connected to the side length of the lower frame 202.
[0014] Preferably, the retractable lever 3 has a button on the handle to control the extension and retraction of the retractable lever 3. When the retractable lever 3 is in the retracted state, the handle of the retractable lever 3 is stored in the groove of the lower frame 2. When the retractable lever 3 is in the extended state, the retractable lever 3 can be pulled out from the lower frame 2, and it is in the state of a trolley case.
[0015] Preferably, the omnidirectional wheels 6 are provided in two sets.
[0016] Preferably, the chair seat has an arc-shaped design, which conforms to ergonomic requirements;
[0017] Preferably, a backrest can be installed on the support frame, and mechanical devices such as an electric massage mechanism can be installed in the internal space of the support frame, transforming it into a functional seat such as a massage chair.
[0018] Compared with existing technologies, this invention has the following advantages: The portable, loading-functional seat described in this invention folds into a "trolley case" structure, occupying little space and facilitating stacking and storage; the retractable handle allows for convenient and effortless one-handed carrying and moving of the seat; furthermore, the internal space of the outer shell and support frame can accommodate heavier items and can also be used to install mechanical devices such as electric massage mechanisms, further expanding the seat's functionality. The mechanical device described in this invention has an ingenious structural design, facilitating the folding, stacking, and movement of the seat; the support frame can be fitted with mechanical devices such as electric massage mechanisms, transforming it into a massage chair or other functional seat, with broad application prospects.
