Abstract
A security cart includes a rear wall, a wheeled base frame connected to the rear wall and a base shelf pivotable between a horizontal position and a raised position. A first sidewall and a first door pivotally connected to the first sidewall are movable from locked positions with the base shelf to a folded position forwardly of the rear wall. A second sidewall and a second door pivotally connected to the second sidewall are movable from locked positions to a folded position forwardly of the folded first sidewall and first door. The base shelf is movable from the horizontal position to the raised position, and retained against the folded first sidewall and the first door and the folded second sidewall and second door.
