ABSTRACT:
A device for taking the weight of a one-leaf or two-leaf door for a switchgear cabinet, a frame of which is made up of profiled bars, in the case of a one-leaf door a free vertical side edge of the door striking against a vertically running profiled bar and in the case of a two-leaf door the vertical free side edges touching or ending at a small distance from one another when the two-leaf door is closed. The device includes at least one guiding element with at least two respective run-up slopes, which in the case of a one-leaf door is arranged in the region on the free side edge and interacts with a run-up edge on the profiled bar against which the door strikes in such a way that, during closing, the guiding element slides with its run-up slope onto the run-up edge and thereby takes part of the weight of the door, and which in the case of a two-leaf door, is arranged in the region of the upper side edge and in the vicinity of the free side edges of each door leaf and, during closing, runs with its run-up slope onto a respective run-up edge at least on the upper horizontally running profiled bar, and consequently takes part of the weight of the door leaves.
