Abstract
A frame assembly for rack-mountable components. A rectangular top frame having a tubular perimeter is connected by four vertical rails to a bottom frame which also has a tubular perimeter as well as tubular members which span it. Both and top and bottom frames each provide an unobstructed central area which may be used for ventilation or application of electromagnetic shielding.
Claims33
A load-bearing frame assembly for rack-mountable equipment, said assembly comprising:
- a rectangular top frame comprising a panel having a tubular perimeter which surrounds a substantially unobstructed central area, and four downwardly extending vertical supports attached to the perimeter and disposed, respectively, near the four corners of the top frame, said panel having an integral C-shaped edge and a brace attached thereto, said brace having a vertical portion and two integral horizontal portions extending in opposite directions from opposite ends of the vertical portion and being disposed such that one of said horizontal portions is attached to and bearing upon said panel and the other horizontal portion is attached beneath and supporting an upper portion of the C-shaped edge, whereby the tubular perimeter is formed around said panel;
- a rectangular bottom frame comprising a tubular perimeter and two parallel tubular members which span said bottom frame perimeter, thereby defining a substantially unobstructed central area, and four upwardly extending vertical supports attached to said bottom frame perimeter, said bottom frame vertical supports being disposed, respectively, near the four corners of the bottom frame and corresponding in position to the four top frame vertical supports;
- and
- four vertical rails connecting said top and bottom frames, each of said rails connected between a pair of corresponding supports and including means for securing one or more rack-mountable components.

A load-bearing frame assembly for rack-mountable equipment, said assembly comprising:
- a rectangular top frame comprising a panel having a tubular perimeter which surrounds a substantially unobstructed central area, and four downwardly extending vertical supports attached to the perimeter and disposed, respectively, near the four corners of the top frame;
- a rectangular bottom frame comprising two pairs of first and second nesting members each having an inverted U-shaped cross-section and flanged edges which overlap, thereby forming a tubular perimeter and two parallel tubular members which span said bottom frame perimeter and defining a substantially unobstructed central area, and four upwardly extending vertical supports attached to said bottom frame perimeter, said bottom frame vertical supports being disposed, respectively, near the four corners of the bottom frame and corresponding in position to the four top frame vertical supports;
- and
- four vertical rails connecting said top and bottom frames, each of said rails connected between a pair of corresponding supports and including means for securing one or more rack-mountable components.

- a rectangular bottom frame having a tubular perimeter and two parallel tubular members which span said bottom frame perimeter and comprising two pairs of first and second nesting members each having an inverted U-shaped cross-section and flanged edges which overlap, each of said pairs of nesting members forming a portion of the tubular perimeter and one of the parallel members, thereby defining a substantially unobstructed central area, and four upwardly extending vertical supports attached to said bottom frame perimeter and corresponding to the four top frame vertical supports, said bottom frame vertical supports being disposed, respectively, between one of the four corners of the bottom frame and an adjacent one of said tubular members, whereby loads applied to said bottom frame are distributed over said bottom frame perimeter and said tubular members;
- and
- four vertical rails connecting said top and bottom frames, each of said rails connected between a pair of corresponding supports and including means for securing one or more rack-mountable components.
