Abstract
Abstract A computer system module assembly has modular equipment enclosures slidable and securable in a modular exoskeletal frame structure on a base. The frame structure includes horizontal frame members on which the enclosures slide with pawls movable on a threaded rod to engage studs on the enclosures to clamp the enclosure to the frame. Air cooling units in the enclosures provide independent cooling for each enclosure, moving air preferably from front to back of the enclosures, through perforated frame doors.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A modular computer frame assembly comprising: a plurality of enclosures, each enclosure having a top, a bottom and sides, and containing computer-related equipment, and a plurality of vertically stacked frame structures for receiving and supporting said enclosures, said frame structures forming discrete structural modular units, each said frame structure comprising a plurality of exterior corner vertical structural members, at least one horizontal frame member secured to said exterior corner vertical structural members and extending horizontally therebetween, said exterior corner vertical structural members including means for attachment to like corner vertical structural members above or below, each said enclosure having enclosure engagement means and each said horizontal frame member having frame engagement means, said enclosure engagement means and said frame engagement means being engageable to each other to clamp said enclosure to said frame member.
Claim 2
Dependent Claim
134 words
A modular computer frame assembly comprising: a plurality of enclosures, each enclosure having a top, a bottom and sides, and containing computer-related equipment, and a plurality of vertically stacked frame structures for receiving and supporting said enclosures, said frame structures forming discrete structural modular units, each said frame structure comprising a plurality of exterior corner vertical structural members, at least one horizontal frame member secured to said exterior corner vertical structural members and extending horizontally therebetween, said exterior corner vertical structural members including means for attachment to like corner vertical structural members above or below, each said enclosure having enclosure engagement means and each said horizontal frame member having frame engagement means, said enclosure engagement means and said frame engagement means being engageable to each other to clamp said enclosure to said frame member.
Claim 3
Dependent Claim
36 words
The assembly of claim 1 in which said horizontal frame member includes means for slidably receiving said enclosure and means for guiding a said enclosure during sliding reception of the enclosure by said horizontal frame member.
Claim 4
Dependent Claim
47 words
The assembly of claim 1 in which said enclosure engagement means includes downwardly extending stud means, said horizontal frame member includes channel means for receiving said stud means and said frame engagement means includes movable pawl means located adjacent said channel means for engaging said stud means.
Claim 5
Dependent Claim
41 words
