发明名称 Table tennis automatic ball server backstop
摘要 A backstop for an automatic ball server has a frame, a net and a curtain. The frame is adapted to be mounted on a table for table tennis. The net is mounted on the frame and is mounted around the automatic ball server. An opening facing the table is defined in the net. The curtain is attached to the net to close the opening in the net, has a gap defined in the curtain through which the automatic ball server can serve balls and is comprised of multiple strips. Each strip has a proximal end attached to the net and a free distal end to allow the ball pass through the curtain and into the net when the ball strikes the curtain. Accordingly, a ball striking the net is slowed down, and the ball can be kept from sticking in the net or rebounding onto the table.
