Height-adjustable volleyball net and standard system and method
First Claim
1. A method of adjusting the height of a volleyball net comprising:
- securing first and second net standards to a support surface, such as a floor, in a manner so that the net standards extend up from the support surface in a generally upright position, each net standard comprising a lower post section and an upper post section slidably connected to the lower post section for telescoping movement of the upper post section relative to the lower post section along a post axis between a raised position and a lowered position;
providing a net and cable assembly comprising a net and a net-supporting cable, the net having an upper edge margin and a cable-receiving sleeve at its upper edge margin, the upper edge margin having first and second ends and a mid-point midway between the first and second ends, the net-supporting cable extending through the cable-receiving sleeve of the net;
operatively connecting the net-supporting cable to the upper post sections of the first and second net standards in a manner so that the net is between the first and second net standards and extends downward from the net-supporting cable;
tensioning the net-supporting cable to a net-supporting tension which is sufficiently great that the elevation of the 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 of the first and second net standards between their raised and lowered positions without reducing the tension of the cable below the net-supporting tension.

Abstract
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.

providing a net and cable assembly comprising a net and a net-supporting cable, the net having an upper edge margin and a cable-receiving sleeve at its upper edge margin, the upper edge margin having first and second ends and a mid-point midway between the first and second ends, the net-supporting cable extending through the cable-receiving sleeve of the net;
operatively connecting the net-supporting cable to the upper post sections of the first and second net standards in a manner so that the net is between the first and second net standards and extends downward from the net-supporting cable;
tensioning the net-supporting cable to a net-supporting tension which is sufficiently great that the elevation of the 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 of the first and second net standards between their raised and lowered positions without reducing the tension of the cable below the net-supporting tension. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)
the step of securing the first and second net standards to the support surface comprises securing the first and second net standards to the support surface in a manner so that the first and second net standards are spaced apart by at least 32 feet; and
the step of providing the net and cable assembly comprises providing the net so that the distance between the first and second ends of the edge margin is at least thirty feet.

10. A method of adjusting the height of a volleyball net comprising:
-
securing first and second net standards to a support surface, such as a floor, in a manner so that the net standards extend up from the support surface in a generally upright position, each net standard comprising a lower post section, an upper post section slidably connected to the lower post section for telescoping movement of the upper post section relative to the lower post section along a post axis between a raised position and a lowered position, and a drive mechanism operable to move the upper post section between its raised and lowered positions;
providing a net and cable assembly comprising a net and a net-supporting cable, the net having an upper edge margin and a cable-receiving sleeve at its upper edge margin, the upper edge margin having first and second ends and a mid-point midway between the first and second ends, the net-supporting cable extending through the cable-receiving sleeve of the net;
operatively connecting the net-supporting cable to the upper post sections of the first and second net standards in a manner so that the net is between the first and second net standards and extends downward from the net-supporting cable;
providing a tensioning mechanism on the upper post section of the first net standard;
using the tensioning mechanism to tension the net-supporting cable between the upper post sections of the first and second net standards to a net-supporting tension which is sufficiently great that the elevation of the 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;
operating the drive mechanism of the first net standard to move the upper post section of the first net standard between its raised and lowered positions without reducing the tension of the cable below the net-supporting tension, and to move the tensioning mechanism therewith; and
operating the drive mechanism of the second net standard to move the upper post section of the second net standard between its raised and lowered positions without reducing the tension of the cable below the net-supporting tension. - View Dependent Claims (11, 12)
