Claim 3

A shelving apparatus according to claim 1 wherein said shelves have a depending flange engageable with the outer faces of the uprights adjacent the corners of the shelves.

Claim 4

A shelving apparatus according to claim 1 wherein said openings in the shelves have a configuration complementary to said tongues in the uprights to non-rotatably receive the same.

Claim 5

A shelving apparatus according to claim 1 wherein said uprights have an L-shaped cross-sectional configuration.

Claim 6

In a free-standing shelving apparatus including a plurality of shelves disposed in vertically spaced relation and a plurality of uprights extending between each shelf and the next lower shelf, the improvement comprising each upright having a pair of lengthwise extending legs longitudinally interconnected to provide a generally L-shaped cross-section, each upright having a socket of L-shaped cross-section opening at one end thereof and a tongue of L-shaped cross-section extending from the other end thereof, each tongue having a cross-sectional thickness sufficiently less than that of the upright to be telescopically receivable in the socket in an endwise aligned upright and each tongue defining a shoulder at its juncture with the upright, at least one of said shelves having a plurality of L-shaped openings arranged in a pattern at spaced locations inwardly of the periphery thereof for receiving the tongues on the uprights.

Claim 7

In a free-standing shelving apparatus including a plurality of shelves disposed in vertically spaced relation and a plurality of uprights extending between each shelf and the next lower shelf, the improvement comprising each upright having a pair of lengthwise extending legs longitudinally interconnected to provide a generally L-shaped cross-section, each upright having a socket of L-shaped cross-section opening at one end thereof and a tongue of L-shaped cross-section extending from the other end thereof, each tongue having a cross-sectional thickness sufficiently less than that of the upright to be telescopically receivable in the socket in an endwise aligned upright and each tongue defining a shoulder at its juncture with the upright, at least one of said shelves having a plurality of L-shaped openings arranged in a pattern at spaced locations inwardly of the periphery thereof for receiving the tongues on the uprights.

Claim 8

In a free-standing shelving apparatus including an upper shelf, at least one intermediate shelf and a base shelf of polygonal configuration disposed in vertically spaced relation and a plurality of uprights extending between each shelf and the next lower shelf adjacent the corners of the shelves, the improvement comprising said intermediate and base shelves having a plurality of openings of L-shaped configuration arranged adjacent the corners of the shelves at locations inwardly of the periphery thereof and with the legs of the L-shaped openings extending generally parallel to the edges of the polygonal shelf, said uprights each having a pair of lengthwise extending legs longitudinally interconnected to provide a generally L-shaped cross-section, each upright having a socket of L-shaped cross-section opening at one end thereof and a tongue of L-shaped cross-section extending from the other end thereof, each tongue having leg portions of a cross-sectional thickness dimensioned less than that of the legs of the upright to extend through an L-shaped opening in the shelf and into the socket in an endwise aligned upright and each tongue defining a shoulder at its juncture with the upright for engaging a face on the shelf around the L-shaped opening therein.

Claim 9

In a free-standing shelving apparatus including an upper shelf, at least one intermediate shelf and a base shelf of polygonal configuration disposed in vertically spaced relation and a plurality of uprights extending between each shelf and the next lower shelf adjacent the corners of the shelves, the improvement comprising said intermediate and base shelves having a plurality of openings of L-shaped configuration arranged adjacent the corners of the shelves at locations inwardly of the periphery thereof and with the legs of the L-shaped openings extending generally parallel to the edges of the polygonal shelf, said uprights each having a pair of lengthwise extending legs longitudinally interconnected to provide a generally L-shaped cross-section, each upright having a socket of L-shaped cross-section opening at one end thereof and a tongue of L-shaped cross-section extending from the other end thereof, each tongue having leg portions of a cross-sectional thickness dimensioned less than that of the legs of the upright to extend through an L-shaped opening in the shelf and into the socket in an endwise aligned upright and each tongue defining a shoulder at its juncture with the upright for engaging a face on the shelf around the L-shaped opening therein.

Claim 10

A shelving apparatus according to claim 6 wherein each upright includes a first and second elongated solid flat core members adhesively joined together to form an elongated generally L-shaped core, and outer and inner panel members adhesively joined to each of the faces of the L-shaped core, one end of the L-shaped core being spaced outwardly in a direction lengthwise of the upright from one end of the panel members to provide said L-shaped tongue and the other end of the L-shaped core being spaced inwardly from the other end of the panel members to provide said L-shaped socket.

Claim 11

A shelving apparatus according to claim 6 wherein said intermediate shelf has a depending flange extending around the outer periphery thereof and spaced outwardly from the L-shaped openings therein a distance to engage both legs of the L-shaped uprights positioned between the intermediate shelf and the next lower shelf.

Claim 12

A shelving apparatus according to claim 6 wherein said base shelf has a depending base flange extending around the outer periphery thereof to space the base shelf above the floor, and means on said base flange engageable with both leg portions of the L-shaped tongues on the uprights when the latter are extended through the L-shaped openings in the base shelf to stabilize the shelving apparatus.

Claim 13

A shelving apparatus according to claim 9, said intermediate shelf having a depending flange extending around the outer periphery thereof and spaced outwardly from the L-shaped openings therein, a distance to engage both legs of the L-shaped uprights positioned between the intermediate shelf and the next lower shelf.

Claim 14

A shelving apparatus according to claim 10 wherein said upper shelf has a depending flange engageable with both legs of the L-shaped uprights positioned between the upper shelf and the next lower shelf.

Claim 15

A shelving apparatus according to claim 6 wherein each upright includes at least two endwise aligned sections each having an L-shaped socket in one end and an L-shaped tongue at the other end.
