Frame construction of a cabinet or cabinets for containing electronic and electric equipments

Abstract

A vertical frame construction of a cabinet or cabinets for electronic and electric equipments, which is favorable in workability for mounting of internal equipments and capable of ensuring a multiplicity of equipment mounting surfaces. The frame construction arranges vertical frame legs 1 of hollow, cross sectional shape at corners, the vertical frame legs 1 having a hollow, cross sectional shape comprising first shaped sides 4 bent inside a box for containing electronic equipments, from outer edge portions 3 , second shaped sides 5 formed by bending inner ends of the first shaped sides 4 in a direction away from a corner 2 , and recessed spaces E, F defined between the first shaped sides and the second shaped sides. Also, equipment mounting holes may be provided to permit work from a side of outer walls of the cabinet, and an extent of projection of joint fittings may be reduced by providing an additional joint fitting mounting side.

         7 . The vertical frame construction of a cabinet or cabinets for electronic and electric equipments, according to    claim 6   , further comprising shaped sides for vertical mounting, which are disposed perpendicular to the shaped sides for outside mounting and the shaped sides for inside mounting and on a side remote from the corner of the cabinet, and include equipment mounting holes.  
     
     
         8 . The vertical frame construction of a cabinet or cabinets for electronic and electric equipments, according to    claim 7   , further comprising a first hollow portion disposed at the corner of the cabinet, and a second hollow portion projecting toward the inner chamber from the first hollow portion and provided with the shaped sides for outside mounting, the shaped sides for inside mounting and the shaped sides for vertical mounting.  
     
     
         9 . The vertical frame construction of a cabinet or cabinets for electronic and electric equipments, according to one of    claims 6    to    8   , wherein the equipment mounting holes on the shaped sides for outside mounting, and the equipment mounting holes on the shaped sides for inside mounting are provided at substantially the same distance from the other outer wall surface of the cabinet perpendicular to the outer wall surface of the cabinet.  
     
     
         10 .
