  • Patent number: 5692981
    Abstract: This invention relates to a game/hockey type puck which utilizes a friction reducing top and bottom surface to reduce the amount of friction and wear when the puck is used on non-ice playing surfaces. In addition a series of side, wing type, slots are provided which aerodynamically enhance the stability of the puck as it travels through the air when hit by a player. Two wing slots or a complete peripheral slot may be provided. The outer cylindrical surface of the puck is curved so that it easily falls over during playing and this curved surface can have several radiuses so that the extreme outermost portion of the curve on which the puck would roll is offset from the central plane of the puck to aid it in tipping over if it was rolling on end. The side friction reducing surfaces of the puck protrude slightly from the sides of the rubber type pucks so that the leading edge of the friction reducing surface is the first to contact and be effected by a variation in the surface quality of the playing surface.
