发明名称 Kit for making an animal maze
摘要 A rugged and inexpensive kit for making an animal maze is especially suited for use by school children. The maze runways may be constructed in any configuration, including non-orthogonal. The kit comprises a plurality of partitions, each having at least one pointed fastener embedded in and projecting from an edge thereof. The partitions may be placed at any location on a bottom plate with the pointed fasteners in contact with the bottom plate. By pounding the partition edge opposite the fasteners, the fasteners are removably inserted into the bottom plate, thereby retaining the partition in an upright attitude. The fasteners are formed with annular flanges to prevent deeper embedding of the fasteners in the partitions with repeated use.
