A tilt-shelf cart system includes spaced, parallel uprights mounted atop a wheeled base with merchandise receiving shelves pivotally mounted between the uprights for limited pivotal movement between forwardly and rearwardly inclined positions. The pivot axes of the shelves are positoned so that the shelves, when fully loaded with merchandise, normally pivot toward their rearwardly inclined positions. The shelves are secured in either of the forwardly or rearwardly inclined positions by a latch mechanism which includes laterally extending latch pins which engage selected edges of a latch plate. The pins are withdrawn by a drawbar mechanism which requires both operator hands to operate. The two-handled drawbar is pivotally connected to a connecting link which, in turn, is pivotally connected to a rotatably mounted plate to cause limited rotation of the plate in response to movement of the connecting link. The plate is connected to each of the latch pins by respective links so that rotation of the plate disengages the latch pins from the plate to allow repositioning of the shelves from one position to the other. The two-handed drawbar feature places both of the operator hands in hazard-free positions at the time the shelves are moved from one position to the other to preclude any mishaps.
