A foldable trampoline includes a bed unit, and a foldable frame unit operable to move between unfolded and folded states, and including first and second frame sections that cooperate to define a bedding space, that are coupled movably to each other and to the bed unit, and that include first and second end parts, respectively. The first end part has a coupling edge formed with a coupling notch, and a guiding edge extending from the coupling edge and formed with a securing notch. The second end part is provided with a coupling shaft to be received movably in the coupling notch, and a securing shaft to be received in the securing notch. The coupling and securing shafts cooperate with the coupling and securing notches to secure the foldable frame unit in the unfolded state, where the bed unit is stretched tensely over the bedding space.

What is claimed is: 1. A foldable trampoline comprising: a bed unit including a bed body and a plurality of anchoring components connected to a periphery of said bed body; and a foldable frame unit operable to move between an unfolded state and a folded state, and including first and second frame sections that cooperate to define a bedding space, that are coupled movably to each other, that have said anchoring components of said bed unit coupled thereto, and that include first and second end parts, respectively; wherein said bed body of said bed unit is stretched tensely over said bedding space when said foldable frame unit is in the unfolded state; wherein said first end part of said first frame section has a coupling edge indented to form a coupling notch that opens in a direction away from said bed body, and a guiding edge extending from said coupling edge and indented to form a securing notch that opens toward said second end part of said second frame section when said foldable frame unit is in the unfolded state; wherein said second end part of said second frame section is provided with a coupling shaft to be received movably in said coupling notch in said coupling edge of said first end part of said first frame section, and a securing shaft to be received in said securing notch in said guiding edge of said first end part of said first frame section; wherein, when said coupling shaft is extended into said coupling notch, and said foldable frame unit is operated to move from the folded state to the unfolded state, said securing shaft is guided along said guiding edge of said first end part of said first frame section and is subsequently received in said securing notch such that said coupling shaft and said securing shaft cooperate with said first end part of said first frame section to secure said foldable frame unit in the unfolded state; wherein said second end part of said second frame section is tubular and is formed with an aligned pair of securing openings and two radial nicks in spatial communication with said securing openings, respectively; wherein said securing shaft includes a shaft body and a plurality of radial securing protrusions mounted on said shaft body, said shaft body being operable to extend through said second end part of said second frame section via said securing openings such that said securing protrusions are extended into said second end part of said second frame section via said nicks; and wherein said securing protrusions prevent said shaft body from moving out of said second end part of said second frame section when said securing protrusions are misaligned with said nicks. 2. The foldable trampoline as claimed in claim 1, wherein: said guiding edge of said first end part of said first frame section has a guide segment extending from said coupling edge, a first notch-confining segment extending from said guide segment in a direction away from said second end part of said second frame section when said foldable frame unit is in the unfolded state, a notch end segment extending from said first notch-confining segment, and a second notch-confining segment extending from said notch end segment in a direction toward said second end part of said second frame section when said foldable frame unit is in the unfolded state, said first and second notch-confining segments cooperating with said notch end segment to define said securing notch, said first notch-confining segment being inclined relative to said second notch-confining segment such that said securing notch gradually diverges in the direction toward said second end part of said second frame section when said foldable frame unit is in the unfolded state. 3. The foldable trampoline as claimed in claim 1, wherein said shaft body has first and second ends, and said securing shaft further includes a curved safety pin having a first pin portion connected pivotally to said first end of said shaft body, and a second pin portion hooked removably onto said second end of said shaft body. 4. The foldable trampoline as claimed in claim 1, wherein said first end part of said first frame section is provided with an inverted-U-shaped bracket that has said coupling edge and said securing edge. 5. The foldable trampoline as claimed in claim 1, wherein each of said first and second end parts of said first and second frame sections is tubular, one of said first and second end parts being provided with a positioning plate that extends into and that abuts against the other one of said first and second end parts when said foldable frame unit is in the unfolded state. 6. The foldable trampoline as claimed in claim 1, wherein each of said first and second frame sections includes pivotally connected frame rods, said first and second end parts being provided on said frame rods of said first and second frame sections, respectively. 7. The foldable trampoline as claimed in claim 1, wherein said foldable frame unit further includes a plurality of supporting legs connected to said first and second frame sections. 8. The foldable trampoline as claimed in claim 1, wherein said first end part of said first frame section has a rounded corner between said coupling edge and said guiding edge.
