Abstract
A knock-down shelving apparatus including a plurality of vertically spaced shelves and a plurality of uprights extending between each shelf and the next lower shelf. Each upright has a multi-sided core and panels adhesively secured to the outer side faces of the core with one end of the core spaced axially outwardly from one end of the panels to provide a multi-sided tongue at one end of the uprights adapted to extend through a similarly shaped opening in the shelf and with the other end of the core spaced axially inwardly of the other ends of the panels to provide a socket for relieving the tongue on an axially aligned upright after it has passed through an opening in the shelf. The shelves have depending flanges engageable with the uprights to enhance the stability of the shelving apparatus when assembled.
Claims12
In a free-standing shelving apparatus including a plurality of shelves of polygonal configuration disposed in vertically spaced relation and a plurality of uprights extending between each shelf and the next lower shelf, the improvement comprising said uprights each including a solid core having a multi-sided configuration and panel members adhesively joined to each of the side faces of the core, one end of the core being spaced axially outwardly from one end of the panel members to provide a multi-sided tongue at one end of each upright and the other end of the core being spaced axially inwardly of the other end of the panel members to provide a multi-sided socket at the other end of each upright dimensioned to non-rotatably receive the tongue on an axially aligned upright, at least some of said shelves having openings adjacent each corner thereof inwardly of the periphery of the shelf for receiving the tongues on the uprights, and said tongues having a length to extend through said openings in the shelves and into the socket in an axially aligned upright.
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.
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.
