US4676384A — Shelf board of laminated material, particularly s…

Claim 1

Independent Claim 289 words

Shelf board formed from plate-like material, such as sheet metal, comprising a generally horizontal plate-like support member having a pair of longitudinal edges and a pair of transverse edges extending transversely of and between the longitudinal edges, said support member arranged to be supported horizontally and having an upper face and a lower face, said support member having a first stiffening profile extending along downwardly and inwardly from each said longitudinal edge and a second stiffening profile extending along and downwardly from each said transverse edge, at least one of said first stiffening profiles forms in combination with said lower face of said support member a closed tubular section extending along and inwardly from at least one said longitudinal edge, said second stiffening profile extending downwardly from said transverse edge and having an angularly shaped section, said at least one first stiffening profile having a first side section extending generally vertically downwardly from one of longitudinal edges of said support surface, a bottom section spaced downwardly from said lower face of said support member and extending generally horizontally inwardly from said first side section located aligned below said support member, and a second side section spaced inwardly from said first side section and extending upwardly from said bottom section to said lower face of said support member whereby the combination of said lower face of said support member, said first and second side sections and said bottom section form the closed tubular section, and said bottom section and second side section form a step-like recessed profile section transverse to said longitudinal edge spaced downwardly from said lower face of said support member so that the step-like recessed profile section is spaced inwardly from said generally vertical first side section.

Claim 2

Dependent Claim 289 words

Shelf board formed from plate-like material, such as sheet metal, comprising a generally horizontal plate-like support member having a pair of longitudinal edges and a pair of transverse edges extending transversely of and between the longitudinal edges, said support member arranged to be supported horizontally and having an upper face and a lower face, said support member having a first stiffening profile extending along downwardly and inwardly from each said longitudinal edge and a second stiffening profile extending along and downwardly from each said transverse edge, at least one of said first stiffening profiles forms in combination with said lower face of said support member a closed tubular section extending along and inwardly from at least one said longitudinal edge, said second stiffening profile extending downwardly from said transverse edge and having an angularly shaped section, said at least one first stiffening profile having a first side section extending generally vertically downwardly from one of longitudinal edges of said support surface, a bottom section spaced downwardly from said lower face of said support member and extending generally horizontally inwardly from said first side section located aligned below said support member, and a second side section spaced inwardly from said first side section and extending upwardly from said bottom section to said lower face of said support member whereby the combination of said lower face of said support member, said first and second side sections and said bottom section form the closed tubular section, and said bottom section and second side section form a step-like recessed profile section transverse to said longitudinal edge spaced downwardly from said lower face of said support member so that the step-like recessed profile section is spaced inwardly from said generally vertical first side section.

Claim 3

Dependent Claim 71 words

Shelf board, as set forth in claim 1, wherein said at least one first stiffening profile has a height extending in the direction downwardly from said support member and a width extending in the direction of said transverse edges, and said at least step-like recessed profile section has a height and a width extending for at least approximately one-third of the cross-section of said at least one said first stiffening profile.

Claim 4

Dependent Claim 111 words

Shelf board, as set forth in claim 1 or 2, including an arrangement of said shelf boards one above the other and forming a shelf compartment between adjacent said shelf boards, said shelf boards having openings in said support members and in said at least one first stiffening profile with said openings being in vertical alignment, vertically arranged partitions for dividing the shelf compartment transversely of the longitudinal edges, means on said partitions for insertion into said openings, and said opening in said at least one first stiffening profile being located in the region of the profile spaced inwardly from said first side section and containing said step-like recessed profile section.

Claim 5

Dependent Claim 47 words

Shelf board, as set forth in claim 3, wherein said step-like recessed profile section has a generally profile in section extending transversely of the longitudinal edges and said openings in said at least one first stiffening profile are located in the region of said Z-shaped profile section.

Claim 6

Dependent Claim 47 words

Shelf board, as forth in claim 3, wherein said means on said partitions for extending into said openings comprise vertically arranged members having a length in the vertical direction less than the corresponding vertical dimension of said at least one first stiffening profile below said support member.

Claim 7

Dependent Claim 49 words

Shelf board, as set forth in claim 5, wherein said vertical members on said partitions arranged to extend downwardly through said support member having a vertical dimension at least greater than the vertical dimension of said step-like recessed profile section downwardly from the lower face of said support member.

Claim 8

Dependent Claim 38 words

Shelf board, as set forth in claim 3, wherein at least certain of said vertical partitions can be assembled from vertical partition sections extending vertically one above the other and means for interconnecting said vertically extending partition sections.

Claim 9

Dependent Claim 41 words

Shelf board, as set forth in claim 7, wherein said partition sections are molded from a synthetic material, said vertical sections have pockets molded therein along the upper and lower surfaces thereof for receiving said means for interconnecting said partition sections.
