An improved collapsible stage panel assembly having a base, a vertical panel rigidly attached to the base, an intermediate panel pivotally connected to the top of the rigid vertical panel, a canopy panel pivotally connected to the intermediate panel and a kicker panel pivotally connected to the bottom of the rigid vertical panel. The stage panel assembly has a mechanical assisting device between the rigid vertical panel and the intermediate panel to provide a counter balancing force against the combined weights of the intermediate and canopy panels. A second mechanical assisting device extends between the intermediate panel and the canopy panel to provide a counter balancing force against the weight of the canopy panel. An automatic locking device provides for the locking of the intermediate panel in its extended position relative to the rigid vertical panel when the intermediate panel is placed in its extended position. The improved panel assembly allows for easier conversion between the extended configuration of the panel assembly suitable for combination with other such assemblies to form an acoustic reflecting shell and the folded storage configuration where the panels can be nested together for storage in a minimum of space.       Recently Added Patents Motion sensor, method, and computer-readable storage medium providing a motion sensor with a validated output signal from the motion sensor Speed-dial and speed-contact with predictive logic Managing metadata for graph-based computations Medical image displaying apparatus, medical image displaying method, and medical image displaying program Multi-interface user terminal Vehicle window molding and method for molding the same Backlight assembly and liquid crystal display having the same   Randomly Featured Patents Semiconductor device having contact pads and method for manufacturing the same Collapsible post structure Water-based electrolyte for electric double layer capacitor and electric double layer capacitor having the same Starting control system of internal combustion engine and starting control method thereof Chafing dish skirt Reverse optical mastering for data storage disk replicas Color-developing compositions and recording material containing same Apparatus and method for electrophoresis in tubes Antagonists of prostaglandin D.sub.2 receptors Instrument with housing having recess for connectors © 2006-2008 PatentGenius.
