Abstract
The present invention provides a pattern-changing walk path on top of which some groove lines and some raised ridges or dots form an anti-skidding layer for children's play and games. The modular design may be disassembled into the units for storage, taking up little room since they can be stacked together, and can be securely attached to one another when put together for use.
Claims6
A wavy tactile walk path, comprising:
- a plurality of basic units with a generally level anti-skid bottom surface for laying on an area of ground, each basic unit having an upper surface having an elevation with at least one undulation and a light curvature in a horizontal plane along its longitudinal axis, said at least one undulation having a peak height in a middle portion so that it gently tapers laterally down towards the sides and longitudinally towards each respective end with an anti-skid padding on the upper surface;
- and
- connectors at each longitudinal of said basic unit so that multiple units can be easily and securely attached together;
- wherein said plurality of basic units are connectable end-to-end in a generally circular shape when the basic units are connected with a consistent orientation of radial curvature, and alternatively are connectable in a curvy line when at least one basic unit is connected with an orientation of radial curvature opposing that of at least one nearest neighbor basic unit.
