ABSTRACT:
A tennis net lifter system includes first and second portable lifter posts positioned adjacent to existing tennis net anchor posts in various positions. A mechanism is included for connecting the lifter posts to the anchor posts. A mechanism is included for telescopically locking the lifter posts at selected heights above the anchor posts. A mechanism is included for raising and lowering the lifter net section along a vertical plane aligned parallel with the existing net such that the player can uniformly bias the lifter net section along a width of the tennis court. In addition to providing at least four alternate net section embodiments, the present invention further includes a portable dolly and a hand-operable winding apparatus for storing and transporting the net sections, respectively.
