Claim 10

A portable system for supporting a volleyball net according to claim 8, wherein the friction means comprise a plurality of spaced apart ridges to impinge against the support line, the ridges extending along the interior faces of the jaw plates in the direction from the bottom of the line-receiving channel diagonally relative to the length of the lien-receiving channel toward the second end of the support line opposite from which the support line enters the line-receiving channel from the net, whereby the ridges are also diagonal to the length of the second end portion of the support line engaged in the line-receiving channel.

Claim 11

A portable system for supporting a volleyball net according to claim 9, wherein the distance across the line-receiving channel separating the ridges of the respective jaw plates increases in the away from the bottom of the line-receiving channel.

Claim 12

A portable system for supporting a volleyball net according to claim 9, wherein the corresponding ridges of the two jaw plates are disposed in substantial alignment with each other.

Claim 13

A portable system for supporting a volleyball net according to claim 8, wherein: the support standards each have a first tubular section, a second section telescopically engagable withn the first section, and means for locking the first and second sections relative engagement with each other; and, the one-way clamping means is mounted on the second section of one of the two support standards.

Claim 14

A portable system for supporting a volleyball net according to claim 12, wherein the second section of the support standard has portions defining longitudinal grooves formed in the exterior of the second section.

Claim 15

A portable system for supporting a volleyball net according to claim 12, wherein the first section of the support standard has portions defining ribs extending longitudinally along the exterior of the first section.

Claim 16

A collapsible volleyball system for supporting a volleyball net at desired elevations, comprising: (a) first and second telescoping standard assemblies, each having: an outer, first tubular section; an inner, second tubular section slidably engagable within a corresponding outer tubular section; and, locking means for locking corresponding outer and inner tubular sections together at selected relative engagements with each other; (b) a support line connectable between the first and second standard assemblies to support the net, the support line having a first end attachable to the first standard assembly and a second end portion; and, (c) means for tensioning the support line to a desired tension level, comprising: means mounted on the second standard assembly for directing the portion of the support line aproaching the second standard assembly from the first standard assembly in a direction downwardly along the length of the second standard assembly; and, one-way clamping means mounted on the second standard assembly for permitting the second end portion of the support line to be drawn through the clamping means in a direction tending to tighten the support line and subsequently tightly holding the second end portion of the support line when the tightening pull on the support line is released, thereby to prevent retraction of the support line.

Claim 17

A collapsible volleyball system for supporting a volleyball net at desired elevations, comprising: (a) first and second telescoping standard assemblies, each having: an outer, first tubular section; an inner, second tubular section slidably engagable within a corresponding outer tubular section; and, locking means for locking corresponding outer and inner tubular sections together at selected relative engagements with each other; (b) a support line connectable between the first and second standard assemblies to support the net, the support line having a first end attachable to the first standard assembly and a second end portion; and, (c) means for tensioning the support line to a desired tension level, comprising: means mounted on the second standard assembly for directing the portion of the support line aproaching the second standard assembly from the first standard assembly in a direction downwardly along the length of the second standard assembly; and, one-way clamping means mounted on the second standard assembly for permitting the second end portion of the support line to be drawn through the clamping means in a direction tending to tighten the support line and subsequently tightly holding the second end portion of the support line when the tightening pull on the support line is released, thereby to prevent retraction of the support line.

Claim 18

A collapsible volleyball system according to claim 15, wherein the one-way clamping means comprises a pair of jaw plates having interior faces disposed relative to each other to define a channel for receiving the second end portion of the support line therein, the interior faces being contured to permit the support line to be drawn through the channel without signficant drag as the support line is being tensioned and then frictionally gripping the support line when the tightening pull on the support line is released.

Claim 19

A collapsible volleyball system according to claim 16, wherein the interior faces of the jaw plates are contoured to define a plurality of spaced-apart ridges extending the jaw plate interior faces from the bottom of the channel diagonally relative to the length of the channel in the direction toward the top of the channel and toward the end of the channel opposite to the end of the channel at which the support line enters the channel from the net.

Claim 20

A collapsible volleyball system according to claim 17, wherein the distance across the channel separating the ridges of the jaw plate interior faces decreases in a direction from the top of the channel to the bottom of the channel to define a generally wedge-shaped, cross-sectional profile.
