Abstract: A computer subsystem including stackable, interlocking, modular peripheral containment enclosures, each the enclosure including broad top and bottom walls held in spaced-apart arrangement by opposed shorter side walls and a rear wall, the walls joined along their respective marginal edges to form an enclosure cavity accessible through the front opening formed thereby, a device extending rearward from the front opening interior the cavity for receiving therealong an enclosed sled containing a computer peripheral, in controlled alignment, the sled including a front face that aligns flush against the front enclosure opening when the sled is fully seated in the cavity, a device for electrically interconnecting the peripheral to a connectable connector in the enclosure, a device for providing an air cooling throughout the cavity including an aperture formed in at least one the side wall for passage of air therethrough, and a device for interconnecting a plurality of the enclosures in horizontal or vertical arrange

Abstract: A self-capturing articulating chest handle including a handle bar of terminal length containing a hand grasping portion, a pair of legs extending downward from the terminal ends of the handle bar, a pair of links, defined by spaced-apart first and second ends, pivotally attached at the first ends to the terminal ends of the legs, outboard thereof, to allow the handle to be swung thereabout, a bracket for mounting against a vertical surface including a pair of mutually spaced-apart ears extending outward therefrom, a first device for pivotally inter-connecting the second link ends to the ears and including an extended element located inboard from the connection interior the links, and a second device formed in the handle bar for fastenable receipt therein of the extended element when the handle is swung downward from a carrying position and rotated about the links into overlapping arrangement therewith and the folded handle legs and links swung further downward against the vertical surface.
