Abstract
Abstract An audience control barrier for use with an elevated stage, for maintaining physical separation for performers on the stage from an audience on the other side of the barrier. The barrier is modular in form, each module including a rigid panel and brackets for supporting the panel in vertical orientation. Interconnection means on the panels permit edge to edge interconnection of modules to form a stage barrier of the desired width. According to a preferred feature, the brackets which support the panels include a top bracket having an angled flange which may be driven into wedging engagement with the top edge of the panel to hold it in place. Means are provided for interconnecting the brackets which support the panels to the legs of the stage. In a preferred form, the interconnection means comprises a hook plate configured to fit around more than half of the periphery of the stage leg, and a flipper or gate which may be moved to locking position to secure the barrier to the stage legs.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
60 words
In combination, an elevated stage having support legs, and a modular audience control barrier secured to said legs near the bottoms thereof, said barrier comprising a plurality of modules, each including a rigid panel and bracket means for supporting said panel in a vertical orientation and in spaced relation to said stage, and means interconnecting said modules in edge-to-edge relationship.
Claim 2
Dependent Claim
60 words
In combination, an elevated stage having support legs, and a modular audience control barrier secured to said legs near the bottoms thereof, said barrier comprising a plurality of modules, each including a rigid panel and bracket means for supporting said panel in a vertical orientation and in spaced relation to said stage, and means interconnecting said modules in edge-to-edge relationship.
Claim 3
Dependent Claim
21 words
The combination of claim 1 in which the interconnecting means enables angular adjustment between said panels when said modules are interconnected.
Claim 4
Dependent Claim
12 words
The combination of claim 1 in which said barrier surrounds said stage.
Claim 5
Dependent Claim
101 words
A modular audience control barrier for use with an elevated stage having support legs, said barrier comprising a plurality of modules each including a rigid panel and bracket means for supporting said panel in a vertical orientation, and means interconnecting said modules in edge-to-edge relationship, said bracket means comprising a vertical member, a horizontal member connected to said vertical member, and means for securing the bottom portion of said panel, said vertical member including means for securing the upper portion of said panel, and said horizontal member including means for interconnection with the lower end of a leg of said stage.
Claim 6
Dependent Claim
101 words
A modular audience control barrier for use with an elevated stage having support legs, said barrier comprising a plurality of modules each including a rigid panel and bracket means for supporting said panel in a vertical orientation, and means interconnecting said modules in edge-to-edge relationship, said bracket means comprising a vertical member, a horizontal member connected to said vertical member, and means for securing the bottom portion of said panel, said vertical member including means for securing the upper portion of said panel, and said horizontal member including means for interconnection with the lower end of a leg of said stage.
Claim 7
Dependent Claim
23 words
Apparatus according to claim 4 in which said horizontal member is adjustable telescopically to vary the distance of said barrier from said stage.
Claim 8
Dependent Claim
21 words
Apparatus according to claim 4 in which said vertical member is adjustable telescopically to secure the upper edge of said panel.
Claim 9
Dependent Claim
87 words
Apparatus according to claim 6 in which said means for receiving said upper edge of said panel comprises a top member connected to said vertical member for extending at least part way across the top edge of said panel and a flange member extending from the top member downwardly and at a small angle outwardly from the face of the panel, whereby said flange and said vertical member may be wedged into secure relationship with the top edge of said panel by driving said vertical member downward.
Claim 10
Dependent Claim
37 words
Apparatus according to claim 4 in which the last-named means includes a hook plate for receiving the stage leg and a flipper or gate operable in a closed position to maintain said leg in said hook plate.
Claim 11
Dependent Claim
104 words
A modular audience control barrier, for use with an elevated stage having support legs, said barrier comprising, a plurality of modules, each including a rigid panel and bracket means for supporting said panel in a vertical orientation, means for interconnecting said modules in edge-to-edge relationship; said bracket means comprising a telescoping vertical member, a telescoping horizontal member rigidly connected to said vertical member, and means for receiving the bottom edge of said panel, said vertical member including means for receiving the upper edge of said panel; and said horizontal member including means for interconnection with the lower portion of a leg of the stage.
Claim 12
Dependent Claim
104 words
A modular audience control barrier, for use with an elevated stage having support legs, said barrier comprising, a plurality of modules, each including a rigid panel and bracket means for supporting said panel in a vertical orientation, means for interconnecting said modules in edge-to-edge relationship; said bracket means comprising a telescoping vertical member, a telescoping horizontal member rigidly connected to said vertical member, and means for receiving the bottom edge of said panel, said vertical member including means for receiving the upper edge of said panel; and said horizontal member including means for interconnection with the lower portion of a leg of the stage.
Claim 13
Dependent Claim
121 words
Apparatus according to claim 9 wherein said means for interconnecting said horizontal member with the lower portion of a stage comprises: a hook plate and means securing it to said horizontal member, said hook plate extending parallel to and beyond said end of said member, said hook plate being configured in conformity with the cross sectional configuration of the lower portion of said stage leg to engage more than half the periphery thereof; and a flipper pivotally connected to said hook plate for movement between an open position, in which it enables lateral insertion of said stage leg into said hook plate, and a closed position, in which it prevents lateral movement of said stage leg out of said hook plate.
Claim 14
Dependent Claim
48 words
Apparatus according to claim 10 in which said means securing said hook plate to said horizontal member comprises a vertical spacer member, whereby said hook plate engages said stage leg a distance above floor level to clear floor engaging devices at the bottom portion of the stage leg.
Claim 15
Dependent Claim
52 words
Apparatus according to claim 10 wherein said hook plate has an L-shaped configuration for engaging two sides of a rectangular cross sectioned stage leg, and a hook tip portion for engaging a third side of said leg, said flipper positioned for engaging the fourth side of said leg in its closed position.
Claim 16
Dependent Claim
42 words
Apparatus according to claim 12 wherein said hook plate is adapted for engaging a square cross sectional stage leg, whereby two such barrier modules can be positioned at right angles with their adjacent bracket horizontal members interconnected to the same stage leg.
