US4478331A — Container for printed-circuit boards

Claim 1

Independent Claim 246 words

A container for the storage of rectangular printed-circuit boards, comprising: a rectangular prismatic box having an open side; a plurality of rectangular plates insertable into said box through said open side; and spacing means inside said box engageable by said plates for holding same substantially parallel to one another and to a pair of walls of said box, each of said plates being provided on at least one surface with a pair of guide tracks extending substantially parallel to a diagonal of the respective plate and with two sliders per guide track displaceable therealong over a major part of said surface for retaining a printed-circuit board therebetween with edges parallel to those of said plates by engagement of each board edge with a respective slider, said guide tracks being throughgoing slots, each of said sliders including a stem traversing an associated slot, a clip on said stem engageable with an edge of a printed-circuit board, and locking means for immobilizing said clip in a slected position along the associated slot, said stem having a head bearing upon a plate surface opposite said clip, said locking means comprising a lever pivotable on said stem and cammingly engageable with said clip for clamping the respective plate between said clip and said head, said clip having a grooved face confronting a plate surface provided with pointed teeth receivable in the grooves of said face, said teeth being arrayed along mutually perpendicular lines parallel to the sides of said plate.

Claim 2

Dependent Claim 246 words

A container for the storage of rectangular printed-circuit boards, comprising: a rectangular prismatic box having an open side; a plurality of rectangular plates insertable into said box through said open side; and spacing means inside said box engageable by said plates for holding same substantially parallel to one another and to a pair of walls of said box, each of said plates being provided on at least one surface with a pair of guide tracks extending substantially parallel to a diagonal of the respective plate and with two sliders per guide track displaceable therealong over a major part of said surface for retaining a printed-circuit board therebetween with edges parallel to those of said plates by engagement of each board edge with a respective slider, said guide tracks being throughgoing slots, each of said sliders including a stem traversing an associated slot, a clip on said stem engageable with an edge of a printed-circuit board, and locking means for immobilizing said clip in a slected position along the associated slot, said stem having a head bearing upon a plate surface opposite said clip, said locking means comprising a lever pivotable on said stem and cammingly engageable with said clip for clamping the respective plate between said clip and said head, said clip having a grooved face confronting a plate surface provided with pointed teeth receivable in the grooves of said face, said teeth being arrayed along mutually perpendicular lines parallel to the sides of said plate.

Claim 3

Dependent Claim 26 words

A container as defined in claim 1 wherein said clip is rotatable on said stem for selective engagement with mutually perpendicular edges of a printed-circuit board.

Claim 4

Dependent Claim 21 words

A container as defined in claim 1 wherein said guide tracks are symmetrically disposed about a diagonal of the respective plate.

Claim 5

Dependent Claim 32 words

A container as defined in claim 1 or 3 wherein said spacing means comprises a set of ribs perpendicular to said open side on at least one pair of opposite walls thereof.

Claim 6

Dependent Claim 48 words

A container as defined in claim 1 or 3 wherein each of said plates is further provided on said one surface with a second pair of guide tracks paralleling the guide tracks of the first pair for retaining another printed-circuit board by means of additional sliders displaceable therealong.

Claim 7

Dependent Claim 190 words

A container for printed-circuit boards, comprising: a box having an open side; a plurality of generally rectangular plates insertable into said box through said open side; and spacing means inside said box engageable by said plates for holding same substantially parallel to one another in said box, each of said plates being provided with a plurality of guide tracks in the form of throughgoing slots and with sliders displaceable along said slots over a major part of a first surface thereof for retaining a printed-circuit board therebetween, said first surface being provided with a set of transverse projections alongside each of said slots, each of said sliders including a stem traversing an associated slot, a clip on said stem engageable with an edge of a printed-circuit board, a head bearing upon a second plate surface opposite said clip, and a lever pivotable on said stem and cammingly engageable with said clip for clamping the respective plate between said clip and said head, said clip having an indented face confronting said first surface and coacting with said projections for relatively immobilizing said clip in different angular positions relative to said plate.

Claim 8

Dependent Claim 190 words

A container for printed-circuit boards, comprising: a box having an open side; a plurality of generally rectangular plates insertable into said box through said open side; and spacing means inside said box engageable by said plates for holding same substantially parallel to one another in said box, each of said plates being provided with a plurality of guide tracks in the form of throughgoing slots and with sliders displaceable along said slots over a major part of a first surface thereof for retaining a printed-circuit board therebetween, said first surface being provided with a set of transverse projections alongside each of said slots, each of said sliders including a stem traversing an associated slot, a clip on said stem engageable with an edge of a printed-circuit board, a head bearing upon a second plate surface opposite said clip, and a lever pivotable on said stem and cammingly engageable with said clip for clamping the respective plate between said clip and said head, said clip having an indented face confronting said first surface and coacting with said projections for relatively immobilizing said clip in different angular positions relative to said plate.

Claim 9

Dependent Claim 36 words

A container as defined in claim 6 wherein said projections are pointed teeth receivable in parallel grooves of said indented face, said teeth being arrayed along mutually perpendicular lines parallel to the sides of said plate.

Claim 10

Dependent Claim 23 words

A container as defined in claim 6 or 7 wherein said guide tracks extend substantially parallel to a diagonal of the respective plate.

Claim 11

Dependent Claim 23 words

A container as defined in claim 8 wherein each plate is provided with at least two guide tracks symmetrically disposed about said diagonal.

Claim 12

Dependent Claim 39 words

A container as defined in claim 6, 8 or 9 wherein said box is rectangularly prismatic and said spacing means comprises a set of ribs perpendicular to said open side on at least one pair of opposite walls thereof.
