ABSTRACT:
A series of laterally spaced elongated inverted T-shaped bars are coupled together at opposite ends by transversely extending hollow tubes projecting within thin wall tube clamps fixed to the upper surface of the bars at respective ends to form a printed circuit board carrier or rack. The clamps may be loosened for spreading the inverted T-shaped support bars to conform to the width of the printed circuit board whose edges lie adjacent a slotted spline or rail with the edges of the board supported by the base of the inverted T-shaped bars. Alternatively, the plurality of printed circuit boards may be inserted within aligned transverse slots within the splines. Headed bolts projecting upwardly through the ends of the bar, each bear a nut for clamping the thin wall tube clamp onto the top of the base portion of the bars on the ends remote from the spline. The recessed RW 10-14-85 bolt heads in the rack RW 10-14-85 receive the threaded ends of bolts of an underlying a rack to permit interlocking stacking of printed circuit boards on respective racks as a multiple board vertically stacked array. Extended length tubes may join three or more bars affixed to the tubes at longitudinally spaced positions to form an extended length rack bearing a plurality of printed circuit boards in horizontal side-by-side fashion between given pairs of such bars.
