Abstract
Abstract A planar cover for rack or upright cabinets having a quadrangular hollow tube frame has flanges at three of its sides, and is rounded at its front side and provided with a flange at the rounded end. An angle element opened toward the panel cover is provided and does not terminate flush with the flange and is secured thereto, whereby a spring promoting the shielding effect is disposed between that leg of the angular flange which extends parallel to the cover wall after assembly and the appertaining quadrangular capping piece.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
A cover for a rack-type cabinet, which cabinet comprises a frame comprising upper, lower, front and rear hollow tubes and a mounting plate carrying a plurality of aligned tabs extending along the front hollow tube, said cover comprising: a cover panel including first, second, third and fourth sides; said second, third and fourth sides each including a respective flange structure projecting generally perpendicular from said panel for frictionally engaging over said upper, lower and rear hollow tubes, respectively; said first side comprising a rounded section comprising a distal end, and an angle-shaped flange carried by said distal end and including a first leg extending generally parallel to said cover panel and a second leg extending from said first leg towards and generally perpendicular to said cover panel; and an electrostatic shield element carried by said second leg for frictionally engaging the plurality of tabs.
Claim 2
Dependent Claim
144 words
