Abstract
A collapsible table height cart is disclosed for elevating a table top mounted case enclosed machine, such as a voting station for deployment of a direct recording electronic voting machine. The erection of the case on the cart is assisted by a series of pivoting motions over a cart fulcrum for ease of voting station erection by polling place personnel having less than average strength. The collapsed cart is flush to one side of the case. The case and collapsed cart transport on a supporting tracking wheel pair protruding from a lower edge of the case at the collapsed cart. Stowing occurs with the case containing the polling station standing on end in a substantially vertical position. Support of the polling station in the vertical stowed position occurs from both the tracking wheel pair and paired arcuate members extending over the bottom edge of the cart. Rocking of the case on the paired arcuate members away from the tracking casters enables the tracking caster pair to pivot away from the collapsed cart on a tracking caster frame pivoting from the fulcrum support in the middle of the cart. When the tracking casters pivot outwardly from a position flush the surface of the case, support of the case on the cart occurs from an A-frame support with exposed steerable caster wheels supporting one side of the A-frame and the tracking caster wheels supporting the other side of the A-frame. Thereafter, the case tilts on the A-frame support and rocks about the fulcrum from the A-frame side having the steerable caster wheels to the A-frame having the tracking caster wheels. This pivotal motion exposes a leg frame under the case. This leg frame is in turn pivoted downward and away from the case bottom on the side of the A-frame having the steerable casters. A final tilting of the case on the fulcrum of the cart lands the leg frame adjacent the steerable casters with the case in the horizontal position. Once the case is in the horizontal position, the direct recording electronic voting machine and its attendant voting booth can be deployed.
