Abstract

A small-size trampoline includes a frame assembly to support a jumping bed at a required height. The frame assembly includes front and rear frames, two side frames, and front and rear transverse bars connected to and between the two side frames. The front and rear frames and the side frames are so shaped that they could be vertically connected together. Each of the front and rear frames and the side frames includes a horizontal main section of a predetermined length, on which two vertical leg sections are formed. When the front and rear frames and the side frames are vertically connected to one another at the leg sections, they together provide an overall height equal to the height required by the jumping bed, and therefore allow the fully disassembled trampoline to have a largely reduced volume for economical packing.

Claims

1. A small-size trampoline, comprising a frame assembly consisting of a front and a rear frame, two side frames, and a front and a rear transverse bar extended between and connected at two ends to predetermined positions on said two side frames;

and a jumping bed fixedly supported on a top of said frame assembly in a tensely and elastically stretched state to locate at a required height;

said front and rear frames and said two side frames being so shaped that they could be vertically connected together with said two side frames located at an upper position;

each of said front and rear frames including a horizontal main section of a predetermined length, on which two upward first leg sections are formed; and

each of said two side frames including a horizontal main section of a predetermined length, on which two downward second leg sections are formed; and

said first leg sections having free ends adapted to vertically detachably connect to free ends of said second leg sections to provide an overall height equal to said height required by said jumping bed.

2. The small-size trampoline as claimed in claim 1, wherein said front and said rear frame are two U-shaped frames, and said two side frames are two inverted U-shaped frames matching said U-shaped front and rear frames.

3. The small-size trampoline as claimed in claim 1, wherein either said first or said second leg sections have diameter-reduced free ends, while the other said second or first leg sections to be connected thereto have free ends having a bore each;

and said diameter-reduced free ends being adapted to vertically insert into said free ends with said bores.

4. The small-size trampoline as claimed in claim 3, wherein each of said diameter-reduced free ends has an elastically movably ball assembly pre-mounted therein, and each of said free ends with said bores is provided with through holes corresponding to said ball assembly.

5. The small-size trampoline as claimed in claim 1, wherein said front and rear transverse bars and said horizontal main sections of said two side frames together constitute a four-side frame needed to support and stretch said jumping bed.

6. The small-size trampoline as claimed in claim 5, wherein said four-side frame are covered with jacket tubes.

7. The small-size trampoline as claimed in claim 1, further comprising a rail assembled to a front side of said frame assembly.

8. The small-size trampoline as claimed in claim 1, wherein each of said front and said rear frame includes two separate inverted T-shaped units, and said two side frames are two inverted U-shaped frames.
