Abstract
Abstract A modular apparatus for constructing a printed circuit board guide and rack is disclosed, comprising a plurality of spaced apart mounting bars and guide rails, each guide rail having a pair of parallelogram-shaped protrusions at each end which mate with similarly shaped recesses in the mounting bars. Alignment of the opposed ends of the guide rails in the mounting bars is facilitated by a central rectangular protrusion between said parallelogram shaped protrusions which fits into a recess in said mounting bars and is visible from the exterior sides of said bars. A board receiving groove is located in the guide rail face opposite the protrusions. A frame is provided for assembling the mounting bars in rack relationship; a pair of guide rails, one each above and below the board, is used for each board to be mounted, and a pair of mounting bars is used for each level of guide rails.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A modular component apparatus for constructing a printed circuit board guide and support rack comprising in combination: a longitudinal guide rail having a circuit board edge receiving groove longitudinally disposed in one face thereof; said guide rail having at least one parallelogram shaped protrusion longitudinally positioned at each end of said guide rail on the face opposite said groove, the lower surface of each of said protrusions skewed toward its associated guide rail ends; a mounting bar positioned at each end of said guide rail perpendicular to the longitudinal axis of said guide rail, said bars having a guide rail protrusion receiving recess longitudinally disposed in at least one face thereof; and frame means for joining said mounting bars in rack configuration.
Claim 2
Dependent Claim
122 words
A modular component apparatus for constructing a printed circuit board guide and support rack comprising in combination: a longitudinal guide rail having a circuit board edge receiving groove longitudinally disposed in one face thereof; said guide rail having at least one parallelogram shaped protrusion longitudinally positioned at each end of said guide rail on the face opposite said groove, the lower surface of each of said protrusions skewed toward its associated guide rail ends; a mounting bar positioned at each end of said guide rail perpendicular to the longitudinal axis of said guide rail, said bars having a guide rail protrusion receiving recess longitudinally disposed in at least one face thereof; and frame means for joining said mounting bars in rack configuration.
Claim 3
Dependent Claim
53 words
The apparatus of claim 1 wherein said guide rail has additionally a first rectangular key protrusion extending longitudinally forward of each of said parallelogram shaped protrusions and wherein said mounting bars have first rectangular key protrusion receiving slots disposed along and through their outer edges transverse the longitudinal axes of said mounting bars.
Claim 4
Dependent Claim
61 words
The apparatus of claim 2 wherein said guide rail has additionally a second rectangular key protrusion extending longitudinally rearward of each of said parallelogram shaped protrusions of a width narrower than said parallelogram shaped protrusions and wherein said mounting bars have second key protrusion receiving slots disposed along and through their inner edge transverse the longitudinal axis of said mounting bars.
Claim 5
Dependent Claim
27 words
The apparatus of claim 3 wherein said rectangular key protrusion receiving slots are spaced along said bar at intervals less than the width of said guide rail.
Claim 6
Dependent Claim
17 words
The apparatus of claim 1 wherein said mounting bars have said recesses disposed on two faces thereof.
