<p>A safe design for a demountable trampoline has interlocking tubular sections (20) forming a support ring. At least six tee couplings (24) are spaced around the ring with profiled ends, e.g. with flats, of the ring sections pressed into the couplings. The vertical sections of the coupling have a split construction to locate into the uprights of tubular section support feet. The ring sections are provided with lines of small holes into which the trampoline sheet (38) is clipped.</p> |
