ABSTRACT:
A portable, collapsible system (10) for supporting a volleyball net (20) at desired heights includes a pair of telescoping standard assemblies (12, 14). One end of a support line (18) for supporting the net (20) is attached to the standard assembly (12) with the opposite end of the support line directed to extend downwardly along the standard assembly (14) to engage a one-way cleat (76). The cleat (76) includes a pair of jaw plates (84a, 84b) positioned relative to each other to define an outwardly flaring line-receiving channel (86). The jaw plates (84a, 84b) are contoured to define a plurality of spaced apart ridges (90) extending from the bottom of the channel (86) diagonally outwardly and toward the end of the channel (86) opposite from the end at which the support line (18) enters the channel from the net (20). The ridges (90) permit the support line (18) to be pulled through the channel ( 86) with minimal resistance and then forces the support line downwardly into the channel when the tensioning pull on the support line is released which in turn causes the support line to be tightly gripped by the ridges (90).
