Abstract
Disclosed is a method and apparatus for measuring the drop Y of sports netting (10) strung between opposed posts (14, 16), wherein a datum point (28) is provided on each post, a datum line (42) is provided between the datum points and the distance Y between the datum line and a specified part (38) of the net measured; the height X above ground (40) of the net is extrapolated by providing the datum points (28) at a known height Z above ground (40) and subtracting the measured drop Y from the datum point height Z: the datum line (42) may be a light-weight cord strung between the datum points or a beam of visible or invisible light.
Claims14
A method of measuring the drop of a sports net strung (10) between opposed posts (14, 16), comprising the steps of—i) providing a datum point (28) on each post;
- ii) providing a datum line (42) between the datum point on each post;
- and, iii) measuring the distance Y between the datum line and a specified part (38) of the net.
A method of measuring the height above ground of a sports net (10) strung between opposed posts (14, 16), comprising the steps of:
- i) providing a datum point (28) of known height Z above ground (40) on each post;
- ii) measuring the drop Y of the net;
- and, iii) extrapolating the net height X above ground from the known height Z above ground of a datum point and the measured drop of the net.
A net drop measuring apparatus for a sports net (10) strung between opposed posts (14, 16) comprising:—i) a datum point (28) on each post;
- and ii) a datum line (42) extending between the datum points, whereby the net drop between the datum line and a specified part of the net can be measured.
