Road hockey puck
摘要:
A road hockey puck comprising discs attached to both sides of a larger resilient central member for guiding the resilient and more friction prone member over a hard surface. Several embodiments are disclosed for attaching the discs to the resilient member including a spool having a male member and a female member and a resilient member surrounding a portion of the spool. The male member comprises a disc having a shaft secured thereto and the female member comprises a disc having a sleeve. The shaft is constructed to be removably secured in the sleeve so that the shaft means and sleeve means can be placed through an aperture in the resilient member to hold the resilient member to the spool. The resilient member has a diameter greater than the discs of the male and female members so that it extends past the outer rim of the discs.
