The net is formed of a pair of spaced horizontal tension members, each covered by a fabric strip to which the loops of a continuous length of flexible net cord are fastened so as to orient the flexible net cord perpendicular to the spaced tension members which support the flexible cord as a series of spaced parallel vertical members. The flexible cord may readily separate when struck by a tennis ball to permit the ball to pass through the net, while indicating by their action and the impedance to the ball, that the ball is out of play.

Abstract: A hinged unit that serves as a security door step to prevent opening of a slidable door. The unit consists of a pair of bars pivotably linked together at adjoining ends and of a length to fit in the extended position, between an external bottom side edge of a slidable door and the bottom side edge of the door frame within the bottom channel in which the door slides to block movement of the door in the closed door position. The hinge line is located below the horizontal longitudinal axis of the joined bars in the extended position. A pivoted kicker plate is pivoted to one bar so that downward pressure on the kicker plate serves to raise the hinge point above the horizontal axis so that the bars will fold upward about the hinge point to permit the bars to fold against the door frame along a vertical axis as the door is opened.
