Spark-generating roller skate assembly

Abstract

An improved roller skate assembly in either shoe skate or skate board form is provided which includes a plurality of roller wheels, a frame securing the wheels in spaced relation for rotation and one or more spark generators, each comprising an abrasive surfaced disc or the like connected to a non-load bearing surface of one of the wheels and a sparking element such as a flint or material capable of generating colored sparks releasably held by a resilient flexible holder adjacent the abrasive surface of the disc. The holder vibrates during skating, due to ground shocks transmitted to it through the frame, bringing the sparking element into intermittent contact with the abrasive to intermittently generate sparks for a spectacular unusual effect. The holder preferably includes a metal or plastic coil spring and a fitting which releasably holds the flint and can be adjusted to reposition the flint as it wears. Alternatively, the flint can be in the form of a ball, preferably rotatable and held by a bracket attached to the spring. In another embodiment, the holder includes an arm hinged at one end to the frame, depending therefrom diagonally and supported by a depending spring. The opposite end of the holder bears the fitting and flint or other sparking element. The assembly is inexpensive, durable and economical; and it produces a pleasing, exciting unusual effect when being utilized.
