Claims2
A maze comprising:
- a plurality of posts, each post comprising a center through hole through the longitudinal central axis, a plurality of first longitudinal slots and a plurality of second longitudinal slots alternatively spaced around said center through hole and longitudinally disposed through the length, a plurality of longitudinal gaps spaced around the periphery through the length and respectively disposed in communication with said second longitudinal slots;
- a plurality of stretching members for inserting into said second longitudinal slots to reinforce the structural strength of said posts;
- a plurality of coupling members for connection between two posts longitudinally;
- a plurality of partition members for connection horizontally between two posts, each partition member having two coupling portions at two opposite sides for inserting into said second longitudinal slot s of said two posts;
- wherein:
- each post further comprises pairs of locating holes respectively disposed inside said second longitudinal slots at two opposite ends;
- each coupling member comprises a plurality of coupling portions symmetrically disposed at two opposite ends for respectively fitting into the center through hole and first longitudinal slots on said post, a plurality of longitudinal openings spaced around the periphery corresponding to said first longitudinal slots, and a plurality of retaining strips respectively disposed in said longitudinal openings, each retaining strip having a free end and a raised portion on said free end for fastening to said locating hole on either post.
