20120104915 | DISHWASHER - A dishwasher includes a wash container, in which a rack for holding items to be washed and/or dried is disposed. At least two lateral guide rails are disposed in the wash container for supporting the rack and allowing the rack to be pulled out of the wash container. Each guide rail includes a guide element disposed in a guide path of the guide rail in a longitudinally movable manner. Provided on the guide rail is a stop which limits a longitudinal movement of the guide element along the guide rail. The stop projects in a first position into the guide path, thereby inhibiting a pull-out movement of the rack. When acted upon in opposition to a pull-out direction, the stop is shiftable out of the guide path into a second position and, when acted upon in the pull-out direction of the rack, the stop is fixed in the guide path. | 2012-05-03 |
