Top localization mechanism of bell folding tent frame

Abstract

The present invention provides a top localization mechanism of bell folding tent, in which a top static rib-hub is located on the top center of the whole framework hinged with radial struts, a pole is connected to the bottom side of the top static rib-hub with the tip end in dead joint vertically, a low sliding rib-hub is fit on the pole in moving connection, said low sliding rib-hub is used for hinging to the radial foldable rib set; a spring is set up between the top static rib-hub and the sliding rib-hub, and is in compression state as folding up the tent frame. The top localization mechanism of bell folding tent not only provides a bigger inner space, but also facilitates to operate in pitch-up process saving labor.

1 . A top localization mechanism of bell folding tent frame, in which a top static rib-hub is set upon the tip center of the frame, and hinged to radial struts respectively, and fixed on the tip end of a pole holding a low sliding rib-hub on the stem vertically, and said low sliding rib-hub is hinged to a proper number of radial foldable rib sets; wherein, said pole has a hollow inner and two opposite guide slots, thereby setting a slider in the inner hollow of the pole, a set pin penetrates through the slider and said opposite guide slots to be fixed on the low sliding rib-hub with the both ends; a spring is set up in the hollow inner of the pole between the top static rib-hub and the slider, and is in compression state as folding up the tent frame.  
   
   
       2 . A top localization mechanism of bell folding tent as claimed in  claim 1 , wherein said pole has a location mechanism at the lower portion for locating the low sliding rib-hub on.
