Abstract
A base enables the elevation of a panel to be selectively adjusted. The base includes a fixed flap, a supporting flap assembly and a hinge. The fixed flap is attached to the backside of the panel. The supporting flap assembly supports the panel. The hinge connects the fixed flap and the supporting flap assembly. The supporting flap assembly includes a top flap and a fan-wheel. The top flap has a protrusion on a surface thereof, and the fan-wheel has a plurality of recesses that are positioned to selectively engage the protrusion. The fan-wheel is connected to the top flap by a pivot that enables the fan-wheel to turn with respect to the top flap. The hinge enables the fixed flap and the supporting flap assembly to turn around the shaft of the hinge to position the supporting flap assembly with respect to the fixed flap. The elevation of the base can be adjusted by changing the extent to which the fan-wheel is turned with respect to the top flap.
