Solar sign assembly

Patent ·
OSTI ID:6579984
A display assembly is provided including a base, a D.C. Motor mounted completely within the base, a solar cell operatively mounted to the base, and a sign member rotated by the motor. A sleeve is provided on an elongated shaft connected to the sign member, and that sleeve slips over the motor shaft to provide an interference fit, but not a press fit. The sign has sufficient cross-sectional area to provide enough air-resistance so that, in combination with the interference fit between the shafts, the sign will turn at an appropriate speed for easy reading even though the motor shaft is turning much more quickly.
