Abstract

Abstract An adjustable target for practicing tennis serves on a regulation size tennis court comprises a substantially rectangular frame defining an enclosure through which the tennis balls may pass. The frame includes two mutually slidable U-shaped side members. The upper leg of each side member is slidable in an upper telescoping member and the lower leg of each side member is slidable in a lower telescoping member having a downwardly extending adjustable leg and telescoped within a main upright support telescoped over an upwardly extending arm of a base. A brace extends rearwardly from the top of the frame and is adjustable therewith in a lateral direction for advantageously cooperating in releasably attaching a removable net for receiving, catching and holding the served tennis balls penetrating the opening defined by the frame.
