Abstract
Abstract A metal cabinet comprises a plurality of intersecting panels are which joined together without spot-welds and without exposed raw metal edges by providing the panels with internesting flanges that are internally interconnected by metal screws to provide a smooth exterior surface having a single seam. One of the panels may have an interior wall which terminates in a flange that abuts the other panel wall to provide additional rigidity and a similar smooth joint structure on the interior of the cabinet having a single seam.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
In a cabinet structure with first and second intersecting panels having respective first and second exterior walls, a joint structure comprising: a flange including a first leg extending perpendicularly from the end of the first panel, a second leg extending inwardly of the cabinet from the first leg parallel to the first wall, and a third leg extending from the second leg parallel to the first leg; a second flange including a fourth leg extending inwardly of the cabinet and perpendicularly from the end of the second wall in abutting relation to the second leg, and a fifth leg extending from the fourth leg in abutting relation to the third leg to locate the first leg coplanar with the second wall; and fastening means interconnecting a pair of the abutting flanges to secure the panels together and provide a joint without externally exposed panel edges.
Claim 2
Dependent Claim
145 words
In a cabinet structure with first and second intersecting panels having respective first and second exterior walls, a joint structure comprising: a flange including a first leg extending perpendicularly from the end of the first panel, a second leg extending inwardly of the cabinet from the first leg parallel to the first wall, and a third leg extending from the second leg parallel to the first leg; a second flange including a fourth leg extending inwardly of the cabinet and perpendicularly from the end of the second wall in abutting relation to the second leg, and a fifth leg extending from the fourth leg in abutting relation to the third leg to locate the first leg coplanar with the second wall; and fastening means interconnecting a pair of the abutting flanges to secure the panels together and provide a joint without externally exposed panel edges.
Claim 3
Dependent Claim
34 words
The joint structure of claim 1, wherein: the fastening means interconnect the third and fifth legs to maintain mutual abutment thereof and maintain the coplanar arrangement of the first leg with the second wall.
Claim 4
Dependent Claim
56 words
The joint structure of claim 1, wherein: the second panel includes a third wall interiorly of and parallel to the second wall and abutting the third or fifth legs, the fastening means interconnecting the third leg, fifth leg and third wall to provide a box structure for the second panel and to secure the panels together.
Claim 5
Dependent Claim
25 words
The joint structure of claim 3, wherein: the third wall terminates in a perpendicular sixth leg abutting the first wall to rigidify the joint structure.
Claim 6
Dependent Claim
24 words
The joint structure of claim 4, wherein: the sixth leg extends toward the first leg to provide an interior joint without exposed panel edges.
