ABSTRACT:
A round trampoline having a sectional, circular frame combined with a circular mat of lesser diameter than the frame resiliently supported from the frame by a plurality of radially arranged coil springs. A plurality of U-shaped legs support the frame with each U-shaped leg being of rigid, one-piece construction and rigidly connected to the frame in bridging relation to the joints in the segments of the frame to prevent relative rotation between the segments and eliminate bending of the frame at the joints. The mat includes a pair of intersecting and overlapping strips oriented in perpendicular relation to each other to form a reinforced center jumping area with the portions of the mat externally of the intersecting portions being of mesh material to enable passage of air in order to prevent ballooning of the mat and to eliminate the feeling of being air supported when contacting the mat.
