a radially outer end of each cap 3 and each end of the pivoting pin 4 extends into the pivoting holes 41 on each side of the walls 51 of each slot 11 thereby forming a pivoting axis for the poles 2 alternatively the poles 2 can be directly connected to the connecting hub 1 without a pivoting cap as shown in fig8 referring again to fig5 7 the base 12 extends radially outward except that the base does not extend above the radially outer portions of the slots 11 where the poles 2 are pivotally connected to the walls 51 thereby forming an opening or a void 61 thus the radially inner portion of the base 12 restricts the inner end of the poles 2 from any upward pivotal movement beyond the bottom surface of the base 12 and as a result prevents the poles 2 from any downward pivotal movement beyond a position substantially parallel to the base 12 in the open configuration of the tent see fig5 and 6 moreover the opening or void 61 provided on the radially outer portions of the slots 11 allow the poles 2 to pivotally move upward to the closed configuration of the tent see fig7 in operation similar to.
