Hockey puck having self-leveling means

A street hockey puck comprising

• (a) a cylindrical body having a side, an upper face and a lower face substantially parallel to said upper face, said side, upper face and lower face defining a cavity;
• and
• a weight disposed within said cavity, said weight having at least one linear dimension greater than the distance between substantially parallel faces, and said weight being substantially movable in three dimensions relative to the cavity, such that the weight is free to move within the cavity both parallel and perpendicular to the faces, and having sufficient freedom of movement to permit the weight to permit the central axis of the weight to become angularly offset from normal to the faces and to permit the weight to simultaneously contact both faces so that that puck will more readily topple when rolling on its side.

A street hockey puck resistant to rising from a face to its edge upon interaction with playing surface irregularities comprising

• (a) a cylindrical body having a side, an upper face and a lower face substantially parallel to said upper face, said side, upper face and lower face defining a cavity, and
• (b) a weight for maintaining a face of the puck substantially parallel to the playing surface, said weight disposed within said cavity, said weight having one linear dimension greater than the distance between said substantially parallel faces, and said weight being substantially movable in three dimensions relative to the cavity, such that the weight is free to move within the cavity both parallel and perpendicular to the faces, and having sufficient freedom of movement to permit the central axis of the weight to become angularly offset from normal to the faces and to permit the weight to simultaneously contact both faces so that the puck will more readily topple when rolling on its side.

A process for manufacturing a hockey puck resistant to rising from a face to its edge upon interaction with playing surface irregularities comprising

• (a) forming a cylindrical body having a side, an upper face and a lower face substantially parallel to said upper face, said upper face and lower face being permanently affixed to said side, said side, upper face and lower face defining a cavity, and
• (b) providing within the cavity a weight for maintaining a face of the puck substantially parallel to the playing surface, said weight disposed within said cavity, said weight having one linear dimension greater than the distance between said substantially parallel faces, and said weight being substantially movable in three dimensions relative to the cavity, such that the weight is free to move within the cavity both parallel and perpendicular to the faces, and having sufficient freedom of movement to permit the weight to permit the central axis of the weight to become angularly offset from normal to the faces and to permit the weight to simultaneously contact both of the faces so that the puck will more readily topple when rolling on its side.
