Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 164 words
A metal enclosure, for electrical equipment, having a frame including: i. a plurality of post elements ii. a plurality of cross-arm elements at least two of which are utilised to connected pairs of the post elements, and iii. means for releasably fastening the post elements to the cross-arm elements with a face of the post element abutting a face of the cross-arm element, said fastening means comprising a. a portion of one of said elements having therein a circular hole opening at the abutting face, b. a first annular portion extending from the abutting face of the other element and having a cylindrical external face forming a fit in the circular hole, c. a second annular portion extending from the first annular portion remote from the abutting face said second annular portion being externally frusto-conical and reducing in diameter in the direction away from said abutting face, d. releasable holding means to bear against the two elements to retain the respective faces in abutment.
Claim 2
Dependent Claim 164 words
A metal enclosure, for electrical equipment, having a frame including: i. a plurality of post elements ii. a plurality of cross-arm elements at least two of which are utilised to connected pairs of the post elements, and iii. means for releasably fastening the post elements to the cross-arm elements with a face of the post element abutting a face of the cross-arm element, said fastening means comprising a. a portion of one of said elements having therein a circular hole opening at the abutting face, b. a first annular portion extending from the abutting face of the other element and having a cylindrical external face forming a fit in the circular hole, c. a second annular portion extending from the first annular portion remote from the abutting face said second annular portion being externally frusto-conical and reducing in diameter in the direction away from said abutting face, d. releasable holding means to bear against the two elements to retain the respective faces in abutment.
