Abstract

In accordance with this invention an improved mobile workstation is provided. The workstation has a base frame, a housing attached to the frame, a vertical upright portion also attached to the frame, and a horizontal member having a work surface with the horizontal member being attached to the vertical upright portion. The base frame has a top and a bottom, with the bottom having wheels attached thereto. The housing contains a portable power supply, a battery, a DC/AC converter, a switch, an external outlet, and circuitry, with the circuitry connecting the power supply to the switch and the power supply to an external plug, the switch to the battery, the switch to at least one female connector, and the DC/AC converter to the external outlet. The vertical upright portion extends higher than, or above, the housing, and in the preferred embodiment of the invention, has a locking mechanism to control the height of the horizontal member above the base frame. Preferably the switch has three positions, one position for recharging the power supply, one position for allowing power to flow through the converter from the battery to the external outlet, and one off position. The switch preferably is connected to at least one indicator light.

Claims
