ABSTRACT:
A foldable tent is provided which achieves the desired stretch of a cloth tent body when fully pitched. The foldable tent includes a cylindrical center member comprising a top cylinder and a bottom cylinder detachably coupled to each other. A cylindrical slider having a notch on its inner surface is movably fitted over the center member. An elastic locking member is mounted in the to cylinder of the center member for locking the slider. The locking member has a locking projection snapping into the notch of the slider. A release mechanism for releasing the locking projection from the notch of the slider is received in the bottom cylinder. The tent framework further includes a plurality of ribs. Each the rib is hinged to a corresponding pipe frame and the slider at its opposed ends such that an angle formed between it and the top cylinder when pitching the tent is less than 90.degree.. This foldable tent is easily pitched and struck regardless of tent size. The pipe frames can be easily repaired when they are damaged as a result of long time use.
