Abstract:
An adjustable platform providing a substantially horizontal mounting surface, said platform comprising:a first plate; a second plate pivotally attached to said first plate and rotatable about a first axis mutually parallel to the respective planes of said first and second plates; an elongated support arm connected between said first and second plates and having first and second ends, said first end being pivotally-attached to said first plate at a first position spaced away from said first axis, said first end being rotatable about a second axis oriented parallel to said first axis, a first elongated shaft extending from said first end toward said second end, said second end being pivotally attached to said second plate at a second position spaced away from said first axis, said second end being rotatable about a third axis oriented parallel to said first axis, a second elongated shaft extending from said second end toward said first end, a clamping block arranged between said first and second ends and having first and second clamping portions arranged opposite each other, said first and second shafts being sandwiched between said first and second clamping portions in a parallel, spaced apart relationship, said first and second clamping portions each having a pair of grooves arranged in a parallel, spaced apart relation matched to the spacing of said first and second shafts, said grooves being sized to frictionally contact said shafts in lengthwise interengagement; means for fixing the length of said support arm comprising at least one fastener extending between said first and second clamping portions for attaching said clamping portions together and into a position in which said first and second shafts are fixedly clamped therebetween; and said first plate being fixedly mountable, said second plate being angularly adjustable about said first axis with respect to said first plate, said second plate for providing said substantially horizontal mounting surface when arranged at a predetermined angle to said first plate irrespective of the orientation of said first plate.
