Abstract:
An adjustable stand assembly for mounting at least one stand platform in a variety of positions, said assembly comprising:a base adapted for generally horizontal placement on level ground and including first and second substantially parallel spaced apart side girders, each side girder including a plurality of spaced apart grooves,an upwardly extending generally open framework for mounting the at least one platform, said open framework including:first and second spaced apart side strut assemblies, each strut assembly including a forward strut and a telescopically cooperative rearward strut defining an internal strut and external strut,said forward strut of said first strut assembly being pivotally connected to a first end of said first side girder of said base and the internal one of said rearward strut of said first strut assembly being pivotally connected to said first side girder of said base at a position spaced away from said first end of said first side girder such that the forward strut and rearward strut of the first strut assembly move parallel with each other,said forward strut of said second strut assembly being pivotally connected to a first end of said second side girder of said base and the internal one of said rearward strut of said second strut assembly being pivotally connected to said second side girder of said base at a position spaced away from said first end of said second side girder such that the forward strut and rearward strut of the second strut assembly move parallel with each other,said rearward struts of said first and second strut assemblies being connected together only at upper ends thereof,at least one pivotally fixed transverse support, each pivotally connected at opposite ends to one said forward strut and associated rearward strut, and being adapted to engage said at least one platform such that telescopic adjustment of said rearward struts of said first and second strut assemblies provides a coordinated adjustment of an angle of inclination of said at least one platform, wherein said angle of inclination can be maintained substantially as the framework is pivoted relative to said base, anda stay pivotally connected at upper portions of the forward struts and selectively positionable in respective ones of said grooves for retaining the framework in any one of a plurality of available angled positions relative to the base.
