ABSTRACT:
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.
