Description

Title of the invention: MULTIFUNCTIONAL FOLDING CHAIR FIELD OF THE INVENTION

[0001] The invention relates to the technical field of folding devices. The present invention relates particularly to a multifunctional folding chair. PRIOR TECHNOLOGY

[0002] Most devices used in folding technology are designed to save storage space or reduce transport difficulty, especially when the device is large. Reasonable use of folding technology can bring much convenience, such as a hanging chair in common daily life, in order to reduce its storage space or reduce transport difficulty, it is generally designed to be foldable, for example, the applicant previously applied for patent no. CN202121716004.1, for example, is a folding chair assembly, that is, folding technology applied to the field of chairs, but in practical application it has been found that the folding chair, due to the absence of a basic connecting structure, therefore cannot be applied to the lifting installation method, in order to put it in place, it is necessary to make modifications to its structure, which will greatly increase the complexity of its structure.

[0003] There are also folding chairs that can be raised and lowered. For example, patent document no. 201910068626.9 discloses a folding chair whose base is rotated at the lower end of the frame. The frame, base, and support bar are connected by a flexible linkage. This method of adjustment makes the chair applicable only to the lifting method, thus limiting its use. At the same time, because the base, frame, and support bar are flexibly connected, and the flexible linkage of the base to the frame and support bar, along with the rotating linkage, means that the flexible linkage can easily be deformed by gravity when the chair is suspended, i.e., cause elongation and damage the overall structure of the chair.
