ABSTRACT:
The present invention provides a foldable frame structure, which comprises a limit portion, a canopy portion and a frame body. The limit portion encloses an area with a predetermined figure. The canopy portion is connected with the limit portion. The frame body is connected with the canopy portion for lifting the canopy portion from the limit portion. The frame body further comprises a plurality of cambered areas, a plurality of first overlapping ends, a plurality of second overlapping ends and a plurality of contacting ends. The plurality of contacting ends press against the limit portion respectively. The plurality of first overlapping ends are aligned along an extended direction. Each of the cambered areas is simultaneously connected with another cambered area at the first overlapping end and connected with yet another cambered area at the second overlapping end. Thus, the foldable frame structure can be collapsed for storage by making the plurality of cambered areas come into close contact with one another successively.
