A one-way security gate is disclosed which includes a plurality of rotatable rods which are suspended from a horizontally mounted shaft. These rods hang vertically and are free to rotate about the shaft in a limited arc. This limited arc is oriented so that the individual rods can be rotated upward on one side of the shaft only. Accordingly, the rods rotate to allow objects to pass under the shaft in one direction only. In the preferred embodiment of this gate each rod is mounted both to rotate about the shaft and to hinge in a direction transverse to the plane of rotation. These hinges allow the rods to be pushed out of the vertical plane and thereby prevent trapezoidally-shaped objects such as grocery carts from wedging between a pair of rods.
