ABSTRACT:
A round trampoline having a sectional, substantially circular frame to which a circular mat is resiliently attached to the frame by a plurality of radially arranged springs. The mat comprises a pair of strips arranged perpendicularly to one another to form a reinforced center jumping area. The frame sections advantageously fit together in a double joint arrangement which affords great rigidity to the structure. The trampoline has sections forming the annular frame which are detachably connected to each other. At the ends of each section there is a portion of a generally U-shaped support member attached thereto and which extends downwardly below the frame rail. The portions of the generally U-shaped support that extend below the frame are detachably connectable with each other and secure the connection of the sections when joined with each other.
