Frame for storing printed-circuit boards or the like

Claim 1

A frame for the parallel storage of a multiplicity of flat articles, comprising: a pair of spaced-apart end walls; a first and a second pair of elongate cross-members with coplanar supporting surfaces interconnecting said end walls, the supporting surfaces of said pairs confronting each other and being spaced apart by a distance exceeding a dimension of said articles perpendicular thereto; a first and a second set of guide elements respectively spanning the cross-members of said first and said second pair along their supporting surfaces, respective guide elements of said sets being provided with confronting track channels for receiving opposite edges of an article to be inserted therebetween, said guide elements and said cross-members being provided with interlocking formations enabling separation thereof by a displacement transverse to said cross-members; and first and second retaining bars paralleling adjoining faces of respective cross-members of said first and second pairs for preventing said transverse displacement, thereby holding said guide elements engaged with said cross-members, said formations including a multiplicity of perforations on said faces and projections on overhanging portions of said guide elements protruding between said bars and said faces, said overhanging portions extending over not more than half the width of said faces, said projections occupying not more than half the cross-sections of said perforations for enabling engagement of said cross-members by a further, symmetrical set of guide elements on opposite surfaces of said cross-members.
