ABSTRACT:
A hockey puck (10) for playing roller hockey on a non-ice surface. The puck includes a puck body (12) of circular cylinder configuration in which a minimum of three multi-directional roller wheel assemblies (20) are mounted in symmetrical equiangular relationship about the puck center. Each wheel assembly comprises a cylindrical wheel support body (21) mounted for rotation on a central main axle (22) parallel to the planar slide surfaces (14, 16) of the puck. Each wheel assembly (20) includes at least one set of wheels (30), each wheel journalled for rotation on its own individual axle (32) mounted in a plane perpendicular to the main axle of the wheel assembly. Each wheel support body (21) has a circular cylinder outer surface (27) of a diameter greater than the thickness of the puck body and each wheel (30) in a set has a roller surface (30a) which in a cross section co-planar with the axes of all wheels in the set describes an arc with radius of curvature which exceeds the radial distance of the cylindrical outer surface of the wheel support body (21) from its main axle (22) and is concentric with arcs described by the other roller surfaces in the set, said plurality of wheel assembles thereby allowing a rolling action of at least one of the wheels (30) whenever a force is applied to the puck with a force component parallel to the playing surface.
