Abstract:
A portable sign system being self-contained and having a digital display panel which can be hydraulically raised to a suitable height and subsequently be rotated by a worm gear which is manually driven or electrically driven by a motor. A broad based upper assembly having an UHMW plastic stabilizing plate and rotation plates and attached worm gear drive serves as a rotatable and stabile mount for a digital or other display panel and an attached solar array. The digital display panel is automatically locked in azimuthal position by the worm gear drive without a conscious operator effort. Azimuth orientation of the digital display panel can be effected by a hand crank, manually by an electrical switch, automatically by an onboard computer control or by remote control.
