Height-adjustable volleyball net and standard system and method

摘要

A method for adjusting the height of a volleyball net comprises operatively connecting a net-supporting cable, which supports a net, to upper post sections, tensioning the net-supporting cable to a net-supporting tension which is sufficiently great that first and second ends of the net's upper edge margin does not exceed the elevation of the mid-point of the net's upper edge margin by more than approximately ¾″ (2 cm) when the first and second ends of the net's upper edge margin are at approximately the same elevation, and moving the upper post sections between raised and lowered positions without reducing the tension of the cable below the net-supporting tension.
