Abstract
A hockey puck has a generally cylindrical body having an upper face, a lower face and a circumferential wall with a generally spherical puck element secured centrally within the body and being rotatable with respect to the puck body. In a preferred embodiment, the generally spherical puck element has a weight greater than that of the body and a diameter greater than the distance between the upper face and lower face. The generally spherical puck element is secured within an inner member which in turn has a ring disposed radially outwardly thereof and secured to the inner member. The puck is structurally designed to have the generally spherical puck element have translational and rotational kinetic energy while the body will have translational or translational and rotational kinetic energy. This results an enhanced ability to maintain the puck on the desired path despite roughness of the surface on which it is moving or certain types of impact with other objects.
