Portable Patent Office Chair

The portable patent office chair is a portable outdoor office chair, but the patent has expired due to non-payment of annual fees. Here is a detailed introduction to its structure and features:

Structural Components

• First Support Frame: Equipped with a storage slot and a handle for easy user gripping. The storage slot can partially accommodate the seat plate, and the handle facilitates user portability of the office chair. The first support frame is rotatably connected to the second support frame, allowing relative rotation between the two and providing a basis for folding and unfolding the office chair.
• Second Support Frame: Rotatably connected to the first support frame and slidably connected to the seat plate. It is equipped with a fixed hook that cooperates with a fixed position on the seat plate. When the fixed position is placed over the fixed hook, the second support frame and the first support frame remain in an unfolded state, providing a stable support structure for the office chair.
• Seat Plate: One end is rotatably connected to the first support frame and partially accommodated within the storage slot, while the other end is slidably connected to the second support frame. This connection method allows the seat plate to move flexibly during the folding and unfolding of the office chair. The seat plate is equipped with a fixed position that cooperates with the fixed hook on the second support frame to achieve the unfolding and fixation of the office chair.
• Backrest Assembly: Rotatably connected to the seat plate, it can be adjusted in angle according to user needs, providing comfortable backrest support for the user.

Feature Advantages

• High Portability: The overall structural design facilitates folding, resulting in a smaller volume after folding. Combined with the handle on the first support frame, it is convenient for office workers to carry it outdoors, meeting the needs of outdoor office work.
• High Comfort: The backrest assembly is rotatably connected to the seat plate, allowing users to adjust the backrest angle according to their own needs to find the most comfortable sitting position, providing a comfortable seating experience for office workers.
• Stable Structure: Through the cooperation of the fixed position on the seat plate and the fixed hook on the second support frame, the second support frame and the first support frame can remain stable when the office chair is unfolded, ensuring the safety of the office chair during use.
