Abstract
Abstract A door frame with a lining having a step-shaped portion on each side, which includes two vertical cover parts separated from each other by the lining and extending at a substantially right angle thereto while having one side portion in engagement with the respective adjacent outermost end face section of the step-shaped portions. Each of the two vertical cover parts has a recess at the respective adjacent step-shaped portion of the lining. This recess has arranged therein a dummy strip corresponding in its dimensions substantially to the dimensions of this recess while screws detachably hold the dummy strip in the recess. The dummy strip is covered up toward the outside by cover means at least approximately flush with the adjacent surface of the respective adjacent step.
