Trampoline with improved hooking structure

Abstract

A trampoline with improved hooking structure includes a first annular member, legs, a second annular member, and elastic units. The legs has end fixed to the first annular member. The second annular member is larger than the first annular member and is coupled to the legs and is arranged below the first annular member. The elastic units each include a connection ring attached to an elastic mat, a brace element, and an elastic element. The brace element has a projection end pivoted to the first annular member and two opposite end respectively pivoted to first and second joint members. The first joint member has an opposite end coupled to the connection ring to set the elastic mat within the first annular member. The second joint member has an opposite end coupled to the elastic element and an opposite end of the elastic element is attached to the second annular member.

I claim: 
     
         1 . A trampoline, comprising:
 a first annular member;   a plurality of legs, which has ends attached to the first annular member to be spaced from each other;   a second annular member, which larger in size than the first annular member, the second annular member being coupled to each of the legs, the second annular member being arranged below the first annular member; and   a plurality of elastic units, each of which comprises a connection ring fixed to an elastic mat, a brace element, and an elastic element, wherein the brace element has a projection end pivotally connected to an outer side of the first annular member, the brace element having two opposite ends that are respectively pivoted to a first joint member and a second joint member, the first joint member having a distal end coupled to the connection ring so as to set the elastic mat within the first annular member, the second joint member having a distal end coupled to the elastic element, the elastic element having an opposite end that is attached to an outer side of the second annular member in a circumferentially distributed manner, whereby when the elastic mat is acted upon by a force and gets sinking, each of the brace elements is forced to rotate so as to pull and move each of the elastic elements.   
     
     
         2 . The trampoline according to  claim 1 , wherein the first annular member comprises a plurality of mounting members fixed thereto in a manner of being spaced from each other, each of the mounting members comprising a coupling section formed thereon and protruding therefrom, the coupling section comprising a through hole formed therein for pivotal connection with the brace element. 
     
     
         3 . The trampoline according to  claim 2 , wherein the brace element comprises a first end and a second end, a third end being arranged between the first end and the second end in a manner of outward projecting, the third end being pivoted to the coupling section, the first end and the second end being respectively and pivotally connected to the first joint member and the second joint member. 
     
     
         4 . The trampoline according to  claim 3 , wherein the first joint member and the second joint member are respectively coupled to the connection ring and the elastic element, the connection rings being fixed to and circumferential arranged a circumference of the elastic mat. 
     
     
         5 . The trampoline according to  claim 4 , wherein the second joint member comprises a twist section, the second joint member having a top end that is pivotally connected to the second end about a first direction, the second joint member having a bottom end that is pivotally connected to the elastic element about a second direction that is different from the first direction. 
     
     
         6 . The trampoline according to  claim 1 , wherein the second annular member comprises a plurality of coupling apertures formed therein in a manner of being spaced from each other, the elastic element having two ends each forming a hook respectively coupled to the second joint member and the coupling aperture. 
     
     
         7 . The trampoline according to  claim 1 , wherein each of the legs has an opposite end coupled to a third annular member.
