A TRAMPOLINE Abstract A first aspect provides a trampoline (200) which comprises a first frame member (204), a second frame member (204), a third frame member (204), a pole member (205) 5 and a sleeve joint coupling (300) that couples the first, second, and third frame members and the pole member. The sleeve joint coupling includes a first arm (301) with a first passage, a second arm (302) with a second passage, a third arm (303) extending away from the second arm and including a third passage, and an aperture (305) that terminates at a top rim. The first passage has a first axis, the second and third passages sharing a 10 substantially common axis, the first axis being substantially perpendicular to the substantially common axis, the first axis extending in a vertical direction. The first frame member is received in the first passage, the second frame member is received in the second passage, the third frame member is received in the third passage, and the pole member is received in the aperture to extend away from the first frame member. At least is one of the second and third arms define an uppermost surface (307) of the sleeve joint coupling, the top rim of the aperture being one of disposed substantially flush with the uppermost surface and disposed below the uppermost surface in the vertical direction. |
