Abstract: A display stand for articles of merchandise, such as electronic calculators, which prospective customers may be expected to operate in order to test the suitability of the merchandise. The display stand comprises a housing having back and end walls and a front panel which is pivotally mounted along its top edge to permit the bottom edge to be moved outwardly from the back and end walls of the housing. The top of the display stand comprises a display shelf pivotally mounted along its bottom edge to permit the top edge to be moved between a first position in which it is in overlapping relationship with the front panel and a second position which permits access to the interior of the housing. A lock is provided on the top panel to permit securing of the top panel and the display shelf in the overlapping position to preclude access to the interior of the housing which includes a source of electrical power in the form of a typical 115 volt AC outlet.
