The ornamental design for a tri-axial interlocking toy, as shown and described.
FIG. 1 is a perspective view of a tri-axial interlocking toy, comprising six spheres with interconnecting components oriented along three orthogonal axes;
FIG. 2 is a top plan cut view of FIG. 1 along the lines of 2-2;
FIG. 3 is a right side elevation view, a left side elevation view, a front elevation view, and a bottom plan view due to symmetry about the three orthogonal axes;
FIG. 4 is a perspective view of the tri-axial interlocking toy, oriented as it would appear when resting on a flat surface; and,
FIG. 5 is a perspective view of the tri-axial interlocking toy, illustrating its appearance when in a condition of use.
The broken lines in FIG. 4 indicate a flat surface and form no part of the claimed invention. The broken lines in FIG. 5 show environmental structure associated with the tri-axial interlocking toy in a condition of use.
