Abstract
Abstract A shielded housing for a computer or the like including top and bottom housing parts. The top housing part includes a top wall and two side walls. The bottom housing part includes bottom, front and back walls. An inverted V-shaped channel is carried by the side walls adjacent the lower edges for a cooperating fit between the channels and upturned flanges carried by the bottom wall planar surface. The inner surfaces of the housing parts include shielding for reduction of electrostatic noise from the enclosure. The cooperating fit between the channels and bottom wall flanges provide and improved side wall junction to prevent electrostatic noise from leaking along the side wall edges.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
180 words
An enclosure for carrying an electronic device, said enclosure including an upper housing part and a lower housing part, said upper housing part including a top wall and a pair of side walls extending from opposite side edges of said top wall and defining an inner surface, said lower housing part including a bottom planar surface and a back wall extending upwardly from said bottom planar surface, an inturned flange member extending longitudinally along a side edge of said bottom planar surface, channel means being carried by one of said upper housing part side walls extending longitudinally along a lower edge of said side wall and fitting with said lower housing part flange member, said channel means including a leg in abutting contact with said bottom planar surface, and conductive shielding covering said upper housing part inner surface said bottom planar surface, wherein said abutting contact between said channel leg and said bottom planar surface constitutes means for preventing electric radio wave noise from escaping from said enclosure at the junction of said channel leg and said bottom planar surface.
Claim 2
Dependent Claim
180 words
An enclosure for carrying an electronic device, said enclosure including an upper housing part and a lower housing part, said upper housing part including a top wall and a pair of side walls extending from opposite side edges of said top wall and defining an inner surface, said lower housing part including a bottom planar surface and a back wall extending upwardly from said bottom planar surface, an inturned flange member extending longitudinally along a side edge of said bottom planar surface, channel means being carried by one of said upper housing part side walls extending longitudinally along a lower edge of said side wall and fitting with said lower housing part flange member, said channel means including a leg in abutting contact with said bottom planar surface, and conductive shielding covering said upper housing part inner surface said bottom planar surface, wherein said abutting contact between said channel leg and said bottom planar surface constitutes means for preventing electric radio wave noise from escaping from said enclosure at the junction of said channel leg and said bottom planar surface.
Claim 3
Dependent Claim
48 words
The enclosure of claim 1 wherein said channel means is an inverted V-shape and includes a second leg diagonally extending from said first leg to said upper housing part side wall lower edge, said second leg being generally parallel with and overlying said lower housing part flange member.
Claim 4
Dependent Claim
22 words
The enclosure of claim 1 wherein said top wall constitutes means connected to said back wall for pivotally moving said top wall.
Claim 5
Dependent Claim
41 words
The enclosure of claim 3 wherein said means for pivotally moving said top wall includes a post connected to said side wall, said post including a tab extending rearwardly, said tab being inserted through a slot formed through said back wall.
