Abstract
Abstract A flexible shelf arrangement is provided having a plurality of shelves maintained in spaced parallel, horizontal position by a plurality of vertical parts of equal height disposed therebetween. The shelves are each provided with a plurality of orifices which are vertically aligned with the corresponding orifices on the other shelves. An equal number of vertical uprights extend into the orifices to maintain the lateral stability of the arrangement. Grooves are provided in the vertical parts and in the upper and lower surfaces of each shelf to hold a side panel in a vertical position.

Claim 1
Independent Claim
211 words
An article of furniture comprising a plurality of shelves disposed in parallel spaced horizontal planes with vertical panels therebetween, each shelf being provided with a number n of orifices of a given profile, grooves formed in each surface of said shelves between each succeeding orifice provided therein, a number n of uprights having a profile corresponding to that of said orifices and disposed in the latter, a number n of vertical parts of any given geometrical form arranged between each shelf, the next lower shelf and the floor, means retaining said vertical pArts in position, each vertical part having two orthogonal faces formed longitudinally thereon along the length of each vertical part, each orthogonal face having a longitudinal groove therein, the grooves of each vertical part aligning with the grooves formed in the planar surfaces of two adjacent shelves, each set of said aligned grooves in the planar surfaces of said two adjacent shelves and in two succeeding vertical parts receiving said vertical panels between said adjacent shelves and corresponding vertical parts, whereby two adjacent vertical panels are maintained at right angles with respect to each other, said vertical parts having a compressive strength suitable for maintaining constant the distance between the shelves and between the lower shelf and the ground.
Claim 2
Dependent Claim
211 words
An article of furniture comprising a plurality of shelves disposed in parallel spaced horizontal planes with vertical panels therebetween, each shelf being provided with a number n of orifices of a given profile, grooves formed in each surface of said shelves between each succeeding orifice provided therein, a number n of uprights having a profile corresponding to that of said orifices and disposed in the latter, a number n of vertical parts of any given geometrical form arranged between each shelf, the next lower shelf and the floor, means retaining said vertical pArts in position, each vertical part having two orthogonal faces formed longitudinally thereon along the length of each vertical part, each orthogonal face having a longitudinal groove therein, the grooves of each vertical part aligning with the grooves formed in the planar surfaces of two adjacent shelves, each set of said aligned grooves in the planar surfaces of said two adjacent shelves and in two succeeding vertical parts receiving said vertical panels between said adjacent shelves and corresponding vertical parts, whereby two adjacent vertical panels are maintained at right angles with respect to each other, said vertical parts having a compressive strength suitable for maintaining constant the distance between the shelves and between the lower shelf and the ground.
Claim 3
Dependent Claim
68 words
An article of furniture as set forth in claim 1 wherein each shelf is equipped, on its two horizontal faces, with corresponding orifices whose depth is less than half the thickness of the shelf, and wherein each upright is comprised of several sections whose ends fit into the orifices provided in the upper face of a given shelf and in the lower face of the next higher shelf.
Claim 4
Dependent Claim
26 words
