Abstract
Abstract This invention relates to enclosures for computers, and more particularly to such an enclosure which facilitates access to and shielding of the operative components of a personal computer. The enclosure includes a chassis, a cover for cooperating with the chassis for enclosing a volume to contain operating components of the microcomputer, and interrupted wedge members for coupling the chassis and cover upon relative movement therebetween in a predetermined direction. The interrupted wedge members include a plurality of hooks on one of the chassis and cover and a plurality of pockets on the other, with the hooks and pockets being disposed along two sides of the chassis and cover for entry of hooks into cooperating pockets on movement of the cover into position for cooperation with the chassis in enclosing a volume.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
46 words
An enclosure for a computer, the enclosure comprising: a chassis, a cover for cooperating with said chassis for enclosing a volume to contain operating components of the microcomputer, and wedge members for coupling said chassis and said cover upon relative movement therebetween in a predetermined direction.
Claim 2
Dependent Claim
173 words
An enclosure as claimed in Claim 1 wherein said wedge members comprise a plurality of hooks on one of said chassis and said cover and a plurality of pockets on the other of said chassis and said cover, said hooks and said pockets being disposed along two sides of said chassis and said cover for entry of said hooks into said pockets on movement of said cover in said predetermined direction and into position for cooperation with said chassis in enclosing a volume, each of said hooks having a surface thereof disposed to define a sloping wedge surface, each of said surfaces extending at a predetermined acute angle to said predetermined direction and parallel to the surfaces defined by other hooks along the same side of said one of said chassis and said cover, and said pockets receiving said hooks and cooperating with said sloping wedge surfaces upon movement between said chassis and said cover in said predetermined direction for drawing said chassis and said cover into intimate contact one with the other.
Claim 3
Dependent Claim
50 words
An enclosure as claimed in Claim 2 wherein said hooks and said pockets cooperate for locking and unlocking said cover and said chassis one from the other upon relative movement therebetween over a distance less than one tenth the dimension of said cover in the direction of said predetermined direction.
Claim 4
Dependent Claim
26 words
An enclosure as claimed in Claim 2 or Claim 3 wherein said hooks are carried on said cover and said pockets are carried on said chassis.
Claim 5
Dependent Claim
35 words
An enclosure as claimed in any of Claims 2, 3 or 4 further comprising a pair of trim strips mounted on opposite sides of said chassis and further wherein said trim strips define said pockets.
Claim 6
Dependent Claim
60 words
An enclosure as claimed in any of Claims 2 to 5 wherein said cover comprises a unitary decorative cover means moulded of a mouldable synthetic material for defining a decorative outer surface for at least three sides of said cover, and metallic sheet liner means formed to nest within said decorative cover means for cooperating in defining a shielded volume.
Claim 7
Dependent Claim
79 words
An enclosure as claimed in any of Claims 2 to 5 wherein each of said chassis and said cover is comprised of an electrically conductive material and further wherein said hook and pockets function for drawing said chassis and said cover into intimate engagement establishing an electrically conductive connection therebetween for facilitating the formation by said chassis and cover of a shield against emission of electromagnetic interference from operating components of the computer housed within the enclosure thus formed.
Claim 8
Dependent Claim
58 words
A microcomputer comprising an enclosure as claimed in any preceding claim and further comprising a planar board mounted on said chassis and a plurality of operative components operatively connected with said planar board for together functioning as a personal computer, said chassis and said cover together defining an enclosure extending about said planar board and said operative components.
