  • Patent number: 12559309
    Abstract: A warehouse for the storage and retrieval, by a distribution vehicle, of goods placed on load carriers, includes aisles which are located in a frame and along which the distribution vehicle is able to travel. It further includes storage locations in the frame for the load carriers. The aisles comprise guideways which are fastened to the frame and which each have a rail along which the distribution vehicle is able to travel, as well as side walls along the rail. In order to reduce vibrations in the region of the fastenings of successive guideways and crossings the guideways are each fastened, at their mutually facing ends, by means of at least one connecting element to a horizontal support surface fixed to the frame. The connecting element is located laterally outside the rail and laterally outside the plane in which each side wall extends.

  • Patent number: 12004646
    Abstract: A rack for storing goods has supports which extend between crossbeams. The supports are downwardly open profiles having a first and a second side wall. A horizontal wall connects the side walls and forms a goods support. At least one crossbeam has two slots, each with a locking projection that engages in an opening in the respective side wall. The openings are located in short end portions of the side walls. Central portions form a majority length of the side walls. The end portions are separated from the central portions by a slot which extends from the lower edge of the side wall over a portion of the height of the side wall. The end portions have in the direction toward the lower edge thereof a wall extent which in comparison with the wall extent on the central portion is offset in the direction toward the profile center plane.

A horizontal wall connects the side walls and forms a goods support. At least one crossbeam has two slots, each with a locking projection that engages in an opening in the respective side wall. The openings are located in short end portions of the side walls. Central portions form a majority length of the side walls. The end portions are separated from the central portions by a slot which extends from the lower edge of the side wall over a portion of the height of the side wall. The end portions have in the direction toward the lower edge thereof a wall extent which in comparison with the wall extent on the central portion is offset in the direction toward the profile center plane.
