发明名称 Tennis practice and training aid
摘要 Disclosed is equipment whereby one may sharpen his or her skills in tennis, while practicing alone. The equipment is of the backboard type, incorporating an upright, panel-like structure located at one end of a surface which preferably is lined to simulate half of a tennis court of standard dimensions. The backboard is provided with a reflective surface, extending over the full width and height thereof, whereby the player sees his reflected image, with the image appearing at the opposite side of and being seen through the interstices of a net simulation incorporated in the reflectively surfaced area. A remarkably close simulation of actual playing conditions, providing a visual impression closely duplicating that which a player would experience when facing an opponent in a match, is thereby produced.
