ABSTRACT:
A hockey puck with locking runners of various shapes is self-orienting and highly visible. The puck has runners with notches disposed in holes with protrusions such that the notches and protrusion mate, locking the runners in the puck and aligning the runners in the holes. The puck has a perimeter side wall with a radius of curvature such that the puck self-orients to a horizontal orientation when it rises up on its side. The puck also has a protrusion formed on the side wall that forces the puck into a precessing motion pattern such that the puck self-orients to a horizontal orientation when rolling on its side. The runners may have a portion that extends through the curved perimeter wall past an edge of the puck to prevent the edge from catching on the playing surface and flipping the puck. An indentation is formed in each of a upper and lower surfaces of the puck. The indentations have an interior side wall and bottom wall defining a primary and secondary visible surface respectively. A reflective material is disposed on the visible surface such that the puck is easier to see.
