摘要：The Guard, according to the embodiment described and depicted herein, comprises an elongate, table-top-engaging mount from which rises an inclined ball-rebounding face. The face and rib define an acute angle therebetween, as the face overlies the rib--to define an obtuse angle with the playing side of the table when the Guard is fixed to the table tennis table. Accordingly, the thus backwardly inclined face is disposed over the table net, and reaches back to engage a "play-back" board. The Guard has a channel with a board slidably and frictionally engaged with the channel, so that the reach of the Guard to a "play-back" board can be altered. As a result, the Guard blocks the net, and keeps the ball from falling behind the net and to the floor, so that the ball can remain in play.
