Bell folding tent

Abstract

The present invention provides a bell folding tent typically comprised of awnings and framework consisted of poles, wherein the framework includes a top static rib-hub built upon the top end of a main stick setting on the center vertically, and hanged on with radial ribs, which is combined of several segments and connectors connecting said adjacent segments together, a low sliding rib-hub put on the main stick in sliding fitting for hanging up one ends of braces, the another ends of said braces pivoted on the first segments of the ribs respectively; an elastic piece is set upon the main stick between said low sliding rib-hub with the top end and the bottom end of the main stick with the low end. Due to the saved restoring energy of the stretched elastic piece, as opening the tent, the low sliding rib-hub is pulled down continuously and kept the inner ends of the braces having a downward pulling force so that the outer ends of braces are kept a strutting force upward to support all ribs to brace the tent without any falling down, and not need to attach any holding device, and the service life is increased greatly.

1 . A bell folding tent typically comprised of awnings and framework consisted of poles, wherein the framework includes a top static rib-hub built upon the top end of a main stick setting on the center vertically, and hanged on with radial ribs, which is combined of several segments and connectors connecting said adjacent segments together, a low sliding rib-hub put on the main stick in sliding fitting for hanging up one ends of braces, the another ends of said braces pivoted on the first segments of the ribs respectively; an elastic piece is set upon the main stick between said low sliding rib-hub with the top end and the bottom end of the main stick with the low end.  
   
   
       2 . A bell folding tent as claimed in  claim 1 , wherein said main stick is a tube with an open bottom end, a pair of axial opposite through slots are built upon the side wall, whereby said low sliding rib-hub is attached on the main stick with a joint screw setting on the low sliding rib-hub over the diameter crossing the two axial slots; said elastic piece is set on the hollow cave of said main stick, and fastened on the joint screw with the top end.  
   
   
       3 . A bell folding tent as claimed in  claim 2 , wherein a bottom cap is used for setting on the open bottom end of the main stick with another joint screw; meanwhile the low end of the elastic piece is fastened on the bottom cap at the bottom end of the main stick by the joint screw too.  
   
   
       4 . A bell folding tent as claimed in  claim 1 , wherein a connector connecting the second and third segments of rib includes the first coupling piece and the second coupling piece, within the first coupling piece has an open slot with a pair of retaining holes on the side walls built upon the outer end, said second coupling piece can be plugged into the open slot of the first coupling piece, and has a long slotted hole pivoted on the retaining holes of the first coupling piece via a pivot pin; said first coupling piece extends a pair of projected steps built upon the insides of side walls of the open slot from the round of the retaining holes to the inner; said second coupling piece has a couple of catching beds built upon the both sides below said long slotted hole for touching against the projected steps of the first coupling piece.  
   
   
       5 . A bell folding tent as claimed in  claim 2 , wherein a connector connecting the second and third segments of rib includes the first coupling piece and the second coupling piece, within the first coupling piece has an open slot with a pair of retaining holes on the side walls built upon the outer end, said second coupling piece can be plugged into the open slot of the first coupling piece, and has a long slotted hole pivoted on the retaining holes of the first coupling piece via a pivot pin; said first coupling piece extends a pair of projected steps built upon the insides of side walls of the open slot from the round of the retaining holes to the inner; said second coupling piece has a couple of catching beds built upon the both sides below said long slotted hole for touching against the projected steps of the first coupling piece.  
   
   
       6 . A bell folding tent as claimed in  claim 1 , wherein said first and second segments are connected by a dual-pivot connector.  
   
   
       7 . A bell folding tent as claimed in  claim 2 , wherein said first and second segments are connected by a dual-pivot connector.  
   
   
       8 . A bell folding tent as claimed in  claim 1 , wherein said rib is combined of four segments, the last two segments are in contraction joint as telescoping jib, and a locating device set upon the both parts for preventing them from slipping relatively.  
   
   
       9 . A bell folding tent as claimed in  claim 2 , wherein said rib is combined of four segments, the last two segments are in contraction joint as telescoping jib, and a locating device set upon the both parts for preventing them from slipping relatively.  
   
   
       10 . A bell folding tent as claimed in  claim 6 , wherein said locating device is comprised of a spring and catcher set upon the inside of the inner segment, and a hole corresponding to the catchers built upon the outer segment.
