Tent Frame

Abstract

The utility model discloses a tent frame, comprising two groups of supporting frame rods, wherein two groups of supporting frame rods are arranged side by side, and two supporting frame rods are expanded to form a V shape; wherein each supporting frame rod comprises two upright rods and top rods which are movably connected to top ends of the upright rods respectively, the two top rods are connected by a one-way connecting piece which has an angle limit and is folded downward, and the upright rods and the top rods are connected by a one-way connecting piece which has an angle limit and is folded upward. The lower end of each upright rod is connected to a bottom pivoting seat, each bottom pivoting seat is provided with two pivoting ports for connecting to the upright rods, and two groups of supporting frame rods are connected between two bottom pivoting seats. The utility model is simple in structure, can be folded conveniently and fast into a small volume, and is convenient to use.

What is claimed is: 
     
         1 . A frame supporting a tent in a folded state and an unfolded state, the frame comprising:
 a first sub-frame, arched in the unfolded state, having:
 a first sub-frame end and a second sub-frame end; 
 a first upright rod extending from the first sub-frame end, a first top rod extending from the first upright rod, a second top rod extending from the first top rod, and a second upright rod extending from the second top-rod to the second sub-frame end; and 
   a second sub-frame, arched in the unfolded state, having:
 a third sub-frame end, pivotally connected to the first sub-frame end, and a fourth sub-frame end, pivotally connected to the second sub-frame end, the second sub-frame including a third upright rod extending from the third sub-frame end, a third top rod extending from the third upright rod, a fourth top rod extending from the third top rod, and a fourth upright rod extending from the fourth top rod to the fourth sub-frame end. 
   
     
     
         2 . The frame of  claim 1 , the first sub-frame including:
 a first connector disposed between the first top rod and the second top rod, the first connector allowing the first top rod and the second top rod to fold toward one another in only a first direction to fold the frame into the folded state; and   a second connector disposed between the third top rod and the fourth top rod, the second connector allowing the third top rod and the fourth top rod to fold toward one another in only the first direction to fold the frame into the folded state.   
     
     
         3 . The frame of  claim 2 , further comprising:
 a third connector disposed between the first upright rod and the first top rod, the third connector allowing the first upright rod and the first top rod to fold toward one another in only a second direction to fold the frame into the folded state; and   a fourth connector disposed between the second upright rod and the second top rod, the fourth connector allowing the second upright rod and the second top rod to fold toward one another in only the second direction to fold the frame into the folded state.   
     
     
         4 . The frame of  claim 3 , wherein the second direction is opposite the first direction. 
     
     
         5 . The frame of  claim 1 , further comprising a first bottom pivoting seat pivotally connecting the first sub-frame end to the third sub-frame end, and a second bottom pivoting seat pivotally connecting the second sub-frame end to the fourth sub-frame end. 
     
     
         6 . The frame of  claim 1 , wherein the first and second upright rods each include rod sections. 
     
     
         7 . The frame of  claim 6 , wherein the rod sections telescope. 
     
     
         8 . The frame of  claim 1 , wherein the first sub-frame and second sub-frame exhibit a V-shape in the unfolded state. 
     
     
         9 . The frame of  claim 1 , wherein the first upright rod is adjacent the first top rod and the third upright rod in the folded state. 
     
     
         10 . The frame of  claim 1 , wherein the first, second, third, and fourth top rods are flexible and bent in the unfolded state and relatively straight in the folded state.
