Description
TITLE: TRAMPOLINE WITH IMPROVED HOOKING STRUCTURE
(a) Technical Field of the Invention The present invention relates generally to a trampoline, and more particularly to an improved hooking structure of a trampoline that involves a linkage structure.
(b) Description of the Prior Art A conventional trampoline is composed of a frame, springs, a spring net, and support legs. The frame is generally a circular one and the plurality of springs is used to couple the spring net to the frame. The support legs are mounted under the frame to support the frame away from the ground surface.
To use the trampoline, a user stands on the spring net and jumps up. As stated previously, the spring net is coupled to the frame by the springs. This structure makes it easy to manufacture. However, simply using the springs to achieve supporting and cushioning force acting on the up-and-down moving spring net, particularly the spring being arranged horizontal, while the spring net being movable vertically, the structural strength that is available would be generally insufficient, making it not possible to uniformly spreading and distributing the force acting on the spring net.
In view of these problems, the present invention aims to provide a solution that overcomes such technical deficiencies.

2 SUMMARY OF THE INVENTION
In view of the above problems, the present invention provides a trampoline with improved hooking structure, which comprises: a first annular member, a plurality of legs, a second annular member, and a plurality of elastic units, wherein the plurality of legs have ends attached to the first annular member to be spaced from each other. The second annular member is larger in size than the first annular member. The second annular member is coupled to each of the legs. The second annular member is arranged below the first annular member. The elastic units each comprise a connection ring attached to an elastic mat, a brace element, and an elastic element. The brace element has a projection end pivotally connected to an outer side of the first annular member. The brace element has two opposite ends respectively pivoted to a first joint member and a second joint member. The first joint member has an opposite end coupled to the connection ring so as 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 an outer side of the second annular member in a manner of being circumferentially distributed. As such, when the elastic mat is acted upon by a force and sinks, the brace elements are forced to rotate so as to pull and move the elastic elements.

7 The first joint member 44 has a distal end that is coupled to the connection rings 411 so that the elastic mat 41 is set within the first annular member 10.
The elastic element 43 has two ends each forming a hook 431, which is set in engagement with the second joint member 45 and a respective one of the coupling apertures 31.
The second joint member 45 comprises a twist section 451. The second joint member 45 has a top end that is pivotally connected the second end 422 about a first longitudinal direction. The second joint member 45 has a bottom end that is pivotally connected to the elastic element 43 about a second transverse direction, which is different from and preferably perpendicular to the first direction.
Referring to FIG 5, in use of the trampoline 1 of the present invention, the elastic mat 41 receives and supports a user to rebound thereon. When the elastic mat 41 receives a force acting thereon, the elastic mat sinks and causes the first joint member 44 to move so as to make the third end 423 of the brace element 42 rotating and simultaneously, the second end 422 pulls the second joint member 45 to move. Since the elastic element 43 is fixed at one end thereof to the second annular member 30 and since the end of the elastic element 43 that is coupled to the second joint member 45 receives a force
The elastic element 43 has two ends each forming a hook 431, which is set in engagement with the second joint member 45 and a respective one of the coupling apertures 31.
The second joint member 45 comprises a twist section 451. The second joint member 45 has a top end that is pivotally connected the second end 422 about a first longitudinal direction. The second joint member 45 has a bottom end that is pivotally connected to the elastic element 43 about a second transverse direction, which is different from and preferably perpendicular to the first direction.
Referring to FIG 5, in use of the trampoline 1 of the present invention, the elastic mat 41 receives and supports a user to rebound thereon. When the elastic mat 41 receives a force acting thereon, the elastic mat sinks and causes the first joint member 44 to move so as to make the third end 423 of the brace element 42 rotating and simultaneously, the second end 422 pulls the second joint member 45 to move. Since the elastic element 43 is fixed at one end thereof to the second annular member 30 and since the end of the elastic element 43 that is coupled to the second joint member 45 receives a force
8 acting thereon and is thus stretched, the elastic mat 41 can be supported by both the brace element 42 and the elastic element 43, while the force can be distributed to all the brace elements 40 and allows for quick returning.
Referring to FIGS. 1 and 2, in the embodiment illustrated, every two of the legs 20 are grouped together and the ends thereof that are opposite to the first annular member are curved outward for further extension and combination with each other; while in the embodiment shown in FIG 6, the opposite ends of the legs are coupled to a third annular member 50.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type descril- ?,d above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
