New Patent for Office Chairs
The following several new types of office chairs feature unique patent designs:
A New Type of Office Chair: This office chair has a patent application filed by Anji Yuhui Furniture Co., Ltd. It has a mobile base fixed at the bottom of the seat, with support frames fixed on both sides. An extension assembly is placed inside the support frames, including an extension slot where an extension rod slides. The extension rod has armrests on its surface. Inside the extension rod, there is a fixed slot where two fixed pins slide, and both ends of the fixed pins mesh with a fixed plate. A moving rod is placed inside the extension rod, with a moving ring fixed on its surface. A return spring is set on the moving rod beside the moving ring, and both sides of the moving rod are rotatably connected to connecting rods, with one end fixedly connected to a moving handle. This design allows the armrests to be flexibly adjusted according to the user's needs. By moving the handle to drive the moving rod, the position of the fixed pins can be controlled to achieve the extension and retraction of the extension rod, meeting the requirements for armrest positions of people with different heights and usage habits.
A Stable Office Chair: This office chair has a patent application filed by Chongqing Huimei Furniture Co., Ltd. Its adjusting components include hinges installed between the seat plate and the backrest, and a fixed wing plate on the side surface of the cylinder adjusting base, with a first electric push rod rotatably installed between the wing plate and the backrest. The supporting components include seven support rods arranged in an array on the lower side of the pneumatic lifting rod, with two universal wheels installed on the lower surface of each support rod. A second electric push rod is fixed inside each support rod, with its telescopic end fixed at the lower end of the pneumatic lifting rod, and a guide rod is also fixed at the lower end of the pneumatic lifting rod. The telescopic end of the first electric push rod rotates the backrest around the hinges to adjust the backrest angle. When the support rods are powered on, they adjust the supporting area of the supporting components through telescoping, solving the problem of the office chair's center of gravity shifting backward when the backrest angle is adjusted too much, and improving the stability of the office chair after adjusting the backrest inclination.
A Massage Office Chair: This office chair has a patent application filed by Fujian Rongyao Health Technology Co., Ltd. Its leg rest assembly includes a support plate hinged to the backrest frame, a leg rest slidably placed on the support plate, and connecting rods connected to the support plate and the leg rest. The support plate is equipped with guide rails, on which a first slider is slidably placed and hinged to the backrest frame. The arrangement of the connecting rods is such that when the support plate is driven to flip outward, the first slider drives one end of the connecting rods inward, causing the other end of the connecting rods to drive the leg rest to move outward along the guide rails; conversely, when the leg rest flips inward, it is driven inward by the connecting rods, keeping the leather cover always taut and avoiding wrinkles that affect aesthetics.
