NEW Trampoline

Abstract

A new trampoline, belonging to the field of manufacture technique for trampolines, has an advantage design. An outside frame has short pole 3 fixed under its lower part. A bounce surface 9 connecting with spring components 8 is located in the outside frame. Foot support 5 connects with connection pole 4 which is under the short pole 3 . Fence protect stem 7 fastens with the short pole 3 and foot supporter 5 tightly. The outside frame is composed by sleeve joining of 3 to 8 pieces of long or short frame segments 1, 2 alternately. The short pole 3 is fixed at the point near the ends of long segment 1 . The length ration between the long frame segment 1 and shot frame segment 2 can be 1.1 to 2:1. The distant L between the fixing point H at which the short poles 3 is fixed to the long frame segment 1 and the connecting point A of the end of long frame segment 1 can be 5-30 cm. The short pole 3 , foot supporter 5 and fence protect stems 7 can be held together by an embrace clamp 6 with hinge. Thereby, the design for outside frame is reasonable, makes the foot supporters as equilateral location, intensifies the structure strength of the outside frame, prevents collapse of the outside frame and avoids the structure weakness at the connecting points, makes shape beauty and convenience in assembly and effectiveness in manufacture.

1 . A new trampoline comprising: 
 an outside frame with short poles fixed under its lower part;    a bounce surface connected with spring components located in said outside frame;    foot supporters located under said short poles;    fence protection stems fastened with said short poles and said foot supporters;    said outside frame being composed by 3 to 8 pieces of long and short frame segments alternately through sleeve join;    said short segment frames being connected with the ends of said long segment frame.    
   
   
       2 . The new trampoline of  claim 1 , wherein the length ratio between said long segment frame and shot segment frame is 1.1 to 2:1.  
   
   
       3 . The new trampoline of  claim 1 , wherein the distance L between the fixing point H at which said short pole is fixed to said long segment frame and the ends of said long segment frame is 5-30 cm.  
   
   
       4 . The new trampoline of  claim 2 , wherein the distance L between the fixing point H at which said short pole is fixed to said long segment frame and the ends of said long segment frame is 5-30 cm.  
   
   
       5 . The new trampoline of  claim 1 , wherein said short pole, said foot supporter and said fence protection stems are held together by embrace clamps with hinge.  
   
   
       6 . The new trampoline of  claim 1 , wherein a connection pole is located between said short pole and said foot supporter and connected therein.  
   
   
       7 . The new trampoline of  claim 1 , wherein said long segment frame, short segment frame, short pole, connection pole, foot supporter and fence protection stem are hollow tubes with presetting diameter.  
   
   
       8 . The new trampoline of  claim 6 , wherein said long segment frame, short segment frame, short pole, connection pole, foot supporter and fence protection stem are hollow tubes with presetting diameter.  
   
   
       9 . The new trampoline of  claim 1 , wherein said foot supporter is U shape tube or W shape tube or V shape tube.
