  • Patent number: 9180328
    Abstract: A trampoline comprises a trampoline sheet or mat supported around its periphery from a circumextending support structure by spring couplings, preferably a plurality of helical springs, under tension. The trampoline is provided with a net enclosure in which a generally circumextending net is mounted by respective sheaths on a plurality of poles coupled to the support structure and extending generally upright therefrom. In use, for the greater part of its height, the position of the net corresponds generally to the periphery of the support structure, while lower edge regions of the net are coupled to the periphery of the sheet or mat inboard of the support structure, thereby at least largely preventing a user from falling or treading upon the spring couplings or on an annular pad overlying said couplings, if present.

  • Patent number: 8012065
    Abstract: Embodiments of hollow generally T-shaped couplers suitable for coupling respective ends of two tubular members to an upright member for a trampoline support are disclosed. Neither manufacture of the coupler nor the manner of its coupling between the tubular members and the upright member requires welds. The coupler has a hollow cross piece for coupling with the respective ends of the two tubular members. It also has a hollow upright piece extending from an underside of and intersecting the cross piece that receives in female fashion a male end of the upright member. Both the underside of the cross piece and sides of the upright piece are of split form along their respective lengths. The upright piece is provided with location regions that cooperate with corresponding location regions on the male end of the upright member to locate the upright member longitudinally of the upright piece.
