Abstract
A structure useful in playing a game in which a tethered ball is repeatedly being engaged can be constructed so as to utilize a hinged member connecting a tether for the ball to an upright support mounted on a base. The hinge member is preferably constructed as a unitary body out of a resilient, elastomeric material such as a natural or synthetic rubber so as to include ends which are sufficiently large and massive so as to be incapable of bending connected by a flexible portion shaped so as to permit bending between the ends of the hinge member and so as to permit the ends being twisted relative to one another no more than about 90 degrees when the ends are located so as to be in alignment with one another. The flexible portion also permits twisting between the ends of the hinge member when the ends are not located in alignment with one another. This hinge member serves to control movement of both the tether and the ball carried by the tether so as to provide that the ball may be moved in more or less the manner in which a ball is hit back and forth across a net in a conventional net type game such as tennis, Ping Pong or the like.
