摘要:
A race track assembly (10) that can be assembled from a flat folded configuration for use and disassembled to a flat folded configuration for storage. The race track assembly (10) includes a plurality of track sections (12) that can be positioned end-to-end to form a race track. Each track section (12) consists of a main track (14) and two sides (16 and 18) that are foldable relative to the main track (14). A plurality of couplers (26) are also included for coupling the track section (12) together. The race track assembly (10) also includes a plurality of cross braces (38) positioned at spaced intervals along the length of the race track. Each of the cross braces (38) is coupled to a track section (12) in a manner to maintain the sides (16 and 18) of the track section (12) in a folded configuration. A plurality of risers (50a, 50b and 50c) are also included for supporting the race track in an inclined position. Each of the risers (50a, 50b and 50c) can be unfolded to a track supporting configuration and folded to a flat storage configuration.
摘要:
A structure is provided for creating an elevated subroadbed for an artificial landscape. The structure includes a flexible riser section of a given length that has a generally planar bottom. The riser section also has a generally planar top extending and supported parallel to the bottom so that the height of the section is consistent along its entire length. The riser is provided with first and second side walls, which each have a series of channels that extend into the riser in spaced apart relation. The channels allow the riser to be positioned in a radius. The top forms an elevated surface that enables low-lying areas to be more easily created on the artificial landscape below the elevated surface. A flexible incline section is also provided for creating a roadbed for an artificial landscape. The incline section has a top that extends at an angle relative to its bottom so that the section increases in elevation from one end to the other. Further, the incline section has channels formed therein which allow it to be flexed in either direction. A first flexible incline section may be provided that rises from a base to a higher elevation. A second incline section is provided which starts from the highest elevation of the first section and further increases in elevation. The second incline section and the first section can be placed in abutting relationship to form a roadbed having a continuous grade. Subsequent sections may be provided which further increase the elevation achieved.
