发明名称 Combined golf ball tether and anchor structure
摘要 An upright standard is provided including structure carried by its lower end for support of the standard from a support surface from which a golf ball may be driven. A low horizontally outwardly projecting arm is stationarily supported from the lower end portion of the standard at an elevation spaced above the lower end of the standard. An elongated flexible tether member has one end thereof anchored to the outer free end portion of the arm and a ball simulating a golf ball is anchored to the other end of the tether member. The length of the tether member is equal to at least one and one-half the effective length of the arm and the standard projects above the arm a distance equal to at least the effective length of the tether member. The arm includes relatively extendable base and free end portions with the base end portion anchored to the standard and the latter comprises upper and lower telescopingly engaged end portions removably engaged with each other.
