ABSTRACT:
An apparatus for quick convenient adjustment of the tension and height of volleyball nets comprises a vertically slidable hardware mounting platform on each net post, containing cable-connection hardware, including winch means. Net height is changed by sliding the mount, without the need to disconnect cables. Through an arrangement of pulleys, a single winch tightens both the upper and lower net cables in unison, with equal force. The pulleys double the winch pull, allowing use of a light winch. They can also be configured to provide single pull on the lower cable, for nets with a steel upper cable and a rope lower cable. Two versions of the slidable mount are described; one is a sleeve on the net post, and the other is a track and slide, in which the track is connected to the post, guiding and retaining the slide.
