ABSTRACT:
A collapsible tent frame has two pole position bases and a plurality of reverse U-shaped frame units to combine with the pole position bases to support a tent roof cloth. Each frame unit consists of two main frame poles having their lower ends screwed with the position bases to stand in radiant direction, and a vertical extension pole connected with a main frame pole at one end and with a horizontal extension pole at the other end with a collapsible hinge to form a reverse U-shaped frame unit. After all frame units are assembled with the position bases, two position ropes can be inserted through each frame unit firmly to keep all the frame units spaced apart from each other at a proper distance. Two sustaining bases are provided to sustain the outer-most frame unit pulled upward to form an entrance for this tent.
