Abstract

A housing for a self-supporting interior structure of electrical or electronic apparatus has a front panel and a casing formed of two U-shaped casing members detachably connected with one another via side spacing members. The side spacing members are formed such that lateral depressions extend inwardly from the side spacing members and extend along the depth of the apparatus for accommodating guide elements such that the housing containing the apparatus will slide into a rack. Use of such depressions permits close vertical spacing of adjacent apparatus housings in a rack and also functions as a handle for transporting individual housings.

Independent Claims | See all claims (11)

  1. 1. A housing for a self-supporting interior structure of electrical and electronic apparatus, comprising:upper and lower U-shaped casing members, each casing member having two edge walls, a front panel, and a side connecting and spacing member joining by the edge walls the upper and lower casing members on each of opposite sides of the cabinet; andeach side connecting and spacing member comprising an integral extruded U-shaped channel forming a lateral depression extending inwardly of said casing member edge walls, said channel having flat upper and lower inwardly extending surfaces and a flat vertical wall inwardly of the edge walls extending between the upper and lower surfaces, flanges being provided extending above the upper surface and below the lower surface, said flanges attaching the spacing members to the edge walls, and said vertical wall and upper and lower surfaces of each U-shaped channel forming a guide rail.
  2. 10. A system for supporting electrical and electronic apparatus in a rack, comprising:(a) a cabinet for electrical and electronic apparatus having upper and lower U-shaped casing members, each casing member having two edge walls, a front panel, and a side connecting and spacing member detachably joining by the edge walls the upper and lower casing members on each of opposite sides of the cabinet;(b) each side connecting and spacing member comprising an integral extruded U-shaped channel forming a lateral depression extending inwardly of said casing member edge walls, said channel having flat upper and lower surfaces and a flat vertical wall extending between the upper and lower surfaces, an integral flange being provided on each U-shaped channel upper and lower surface, said flanges attaching the spacing members to the edge walls; and(c) a rack having parallel vertical side walls and horizontal guide elements, said guide elements being receivable in each depression and slidably support said cabinet; whereby said inward depressions provide a grip for hand carrying of the cabinet permit simplified construction of the cabinet, and also allow close spacing of cabinets slidably received in the rack.
