Abstract
Abstract A portable carrel construction consisting of a plurality of longitudinal and transverse crossing opaque barriers is adapted for removable attachment to the upward surface of a table. When a student occupies a chair pulled to the side edge of the table between the crossing barriers, the spatial volume immediate the barriers and above the table is isolated into an individual study space which is insulated from ambient classroom distraction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A sportable carrel construction for forming a three-sided individual study cell on a table having first and second pairs of opposed edges comprising: a first partition adapted to be removably disposed on and to extend longitudinally of said table substantially normal to the upper surface thereof between the first pair of opposed edges of said table to thereby define a first wall of said study cell; a pair of spaced, second partitions coupled to and extending transversely of said first partition and adapted to extend transversely of the table substantially normal to the upper surface thereof between the second pair of opposed side edges thereof to thereby define respective second and third walls of said study cell, each partition having opposed end portions adapted to extend beyond respective edges of the table when the partition is disposed thereon; and depending, table-engaging protrusion means on each end portion, respectively, of each partition for holding the partition against movement of the same over said upper surface of the table in a respective direction.
Claim 2
Dependent Claim
171 words
A sportable carrel construction for forming a three-sided individual study cell on a table having first and second pairs of opposed edges comprising: a first partition adapted to be removably disposed on and to extend longitudinally of said table substantially normal to the upper surface thereof between the first pair of opposed edges of said table to thereby define a first wall of said study cell; a pair of spaced, second partitions coupled to and extending transversely of said first partition and adapted to extend transversely of the table substantially normal to the upper surface thereof between the second pair of opposed side edges thereof to thereby define respective second and third walls of said study cell, each partition having opposed end portions adapted to extend beyond respective edges of the table when the partition is disposed thereon; and depending, table-engaging protrusion means on each end portion, respectively, of each partition for holding the partition against movement of the same over said upper surface of the table in a respective direction.
Claim 3
Dependent Claim
203 words
In combination, a rectangular table having two parallel and elongate side edges and two parallel and shortened end edges; a first opaque partition removably mounted on and extending vertically upward of the surface of said table overlying the central longitudinal axis thereof; said first opaque partition defining a lower edge for contacting the top of said table and having opposed end portions extending beyond the end edges of said table; a plurality of second opaque partitions mounted on and extending vertically upward of the surface of said table parallel to the short and end edges of said table; said second partitions each defining at their lower portion a surface for contacting said table top and having opposed end portions extending beyond respective side edges of the table, said second partitions each being spaced and attached transversely of said first partition to define between pairs of said second opaque partitions three-sided study cells; and a protrusion on each end portion of each partition, respectively, the protrusions of each partition extending downwardly from respective end portions and being in proximity to the adjacent edges of the table to prevent horizontal movement of the partition relative to the surface of the table in a respective direction.
Claim 4
Dependent Claim
203 words
In combination, a rectangular table having two parallel and elongate side edges and two parallel and shortened end edges; a first opaque partition removably mounted on and extending vertically upward of the surface of said table overlying the central longitudinal axis thereof; said first opaque partition defining a lower edge for contacting the top of said table and having opposed end portions extending beyond the end edges of said table; a plurality of second opaque partitions mounted on and extending vertically upward of the surface of said table parallel to the short and end edges of said table; said second partitions each defining at their lower portion a surface for contacting said table top and having opposed end portions extending beyond respective side edges of the table, said second partitions each being spaced and attached transversely of said first partition to define between pairs of said second opaque partitions three-sided study cells; and a protrusion on each end portion of each partition, respectively, the protrusions of each partition extending downwardly from respective end portions and being in proximity to the adjacent edges of the table to prevent horizontal movement of the partition relative to the surface of the table in a respective direction.
Claim 5
Dependent Claim
26 words
The invention of claim 1 and including a hinge dividing said first partition into first and second portions, which portions can be folded in overlying relation.
Claim 6
Dependent Claim
77 words
The invention of claim 3 and wherein one of said hinged portions of said partition has one second partition conjoined thereto and the other of said portions of said hinged partition has two second partitions conjoined thereto and wherein said protrusion means include protuberances at either end of all said first and second partitions for extending immediately below and beyond the side edges of said table for preventing movement of all said partitions in said respective direction.
