Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
A cabinet for electrical installations, said cabinet comprising a carrying frame having front, rear and lateral sides, and including hollow profiled horizontal and vertical supporting elements, said vertical supporting elements each including a laterally projecting channel portion extending the length of the vertical element, the channel portions of two vertical supporting elements at the front and rear sides of the frame facing one another and extending at the lateral sides of the frame, said horizontal supporting elements being hollow profiled members extending at the front and rear sides of the frame between two vertical supporting elements and including threaded bores extending lengthwise thereof, screw members introduced through holes provided in said vertical supporting elements and engaged in said bores for fixing the horizontal supporting elements at the front and rear sides of said frame to the vertical supporting elements, said carrying frame further including side supports at the lateral sides of the frame fixed to the laterally projecting channel members facing each other of a front and rear vertical supporting element.
