Night Puck

摘要

The night puck has a median plane contiguous with a circumference thereof. The centroid of the puck is located at an intersection of the axis of rotation of the puck with the median plane. A cylindrical cavity extends therein along the natural axis of rotation. This cylindrical cavity has a thin membrane-like bottom wall. A series of holes extend radially along the median plane from the cylindrical cavity to the circumference of the puck. An electronic module is mounted in the cylindrical cavity. This electronic module comprises a battery and has a center of gravity that is located on the centroid of the puck. A push-button switch is held against the membrane-like bottom wall for operation of the switch by a depression of the membrane-like bottom wall. A series of diodes are mounted in the radial holes and are connected to the electronic module, for illuminating rays of lights around the puck.

1. A hockey puck comprising:
a toroidal element having an overall diameter and an outside circumference; a median plane contiguous with said circumference; a natural axis of rotation extending at a right angle from said median plane; a centroid located at an intersection of said natural axis of rotation with said median plane; a cylindrical cavity inside said toroidal element extending along said natural axis of rotation and being centered on said natural axis of rotation said cylindrical cavity having a cavity diameter being smaller than said overall diameter of said toroidal element; a series of radial cylindrical holes extending radially in said toroidal element along said median plane, from said cylindrical cavity to said outside circumference of said toroidal element; a metal casing snug-fit mounted in said cylindrical cavity; an electronic module mounted in said metal casing, said electronic module including a battery and having a center of gravity located on said centroid, and said metal casing being snug-fit mounted in said cylindrical cavity; said metal casing having a circumferential wall and radial circular openings in said circumferential wall, said metal casing having anchoring sleeves respectively extending radially through one of said radial circular openings and into one of said radial cylindrical holes of said toroidal element, for anchoring said metal casing to said toroidal element; and each of said anchoring sleeves having a shoulder thereon inside said metal casing for retaining said sleeves to said metal casing; and a series of light sources mounted in said anchoring sleeves and being connected to said electronic module, for illuminating rays of lights around said outside circumference.
