Abstract: A vertically oriented shaft has a vertically oriented central axis. A lower plate has a configuration with an upper surface integrally formed with the lower end of the shaft. An upper plate has a geometric configuration with a periphery, a lower surface integrally formed with the upper end of the shaft, and an upper surface. A base plate has a center located on the central axis of the shaft. The base plate has an upper surface in facing contact with and separably coupled to the lower surface of the lower plate. The system has a reduced center of gravity for maximum safety, particularly for preteen users.

Abstract: A gazebo is fabricated utilizing a novel construction system wherein lightweight aluminum framing components are employed. A preferred structure has eight sides wherein each side includes a pair of vertical posts, a pair of header members, a rail and foot member, columns disposed between the rail and foot member and the pair of header members, and an insulated composite roof panel. An entrance way is void of the rail and foot member, but can be employed with the necessary framing components to attach a door. As each side unit is attached by self mating beam and vertical post members to an adjacent side unit, the gazebo structure is formed. A crown portion can be attached upon an apex of the gazebo. Shingles or tiles can be attached upon the roof panels. Spline grooves formed along the vertical posts permit the gazebo to be “screened in.
