Abstract: The invention relates to a device for installing kitchens comprised of kitchen elements such as lower cupboards, upper cupboards, shelves, kitchen appliances, worktops, sinks, etc., in which a base element, which stands on the floor, is provided for mounting at least one lower kitchen element. A vertically upwardly extending retaining element is joined to the rear end of the base element and can serve to fasten at least one upper kitchen element. The use of the device, which is problem-free not only for professional installers, makes it possible to install kitchen appliances regardless of the location of wall connections for electricity, water, gas, etc. The frame-like design eliminates the need to make holes in the kitchen wall for fastening the upper cupboards.
