Abstract
Abstract A carrel-like module which, in one configuration, accommodates a single user, and in an expanded configuration, accommodates two or more users. The carrel module includes an arcuate shaped writing panel, preferably having a concavely shaped rear edge opposite from a seated user and a convexly shaped near edge presented adjacent the seated user, with two end edges, respectively, connecting the rear and near edges. The end edges and the rear edge are bounded by upright panels, the panels extending generally above the writing panel to the head level of the seated user. The two panels presented adjacent the respective end edges are rotatably connected to leg-like support members located at corners of the writing panel formed by the intersection of the rear edge and the end edges, respectively, of the writing panel. The end panels are removably secured to the writing panel, such that they may be conveniently disengaged therefrom, and rotated about their associated leg members by the user. The associated leg members include integral stop elements arranged therewith to prevent further rotation of the end panels when they are coplanar with the nearest panel presented adjacent the rear edge. Hinged to the respective end edges of the writing panel are writing panel extensions, which extensions are held against the undersurface of the writing panel in the closed position. When the end panels are rotated to be coplanar with their adjacent rear edge panels, the writing panel extensions may be rotated from their closed position about the respective writing panel edges to an extended position coplanar with the writing panel, so as to extend the surface of the writing panel adjacent the rotated end panels.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
252 words
An educational module comprising: a generally horizontally positioned writing panel having a near edge presented adjacent a seated user, a rear edge, and two end edges connecting said near and rear edges, wherein intersections of said two end edges and said rear edge define first and second writing panel corners; supporting means for said module, including at least two upright support members which extend from a support surface to a point above said writing panel, said two support members being positioned adjacent said first and second writing panel corners; vertical panel means partially enclosing said writing panel, said vertical panel means being supported adjacent said end edges and said rear edge of said writing panel, said vertical panel means extending from a point below said writing panel to a point above said writing panel at least to head level of the seated user, said vertical panel means including two end panels supported adjacent said end edges, at least one of said two end panels being movable between two spaced operative positions without disturbing the structural integrity of the module, one of said two spaced positions being adjacent one end edge of said writing panel, the other of said two spaced positions being relatively away from said one end edge of said writing panel; and means securing said vertical panel means to said supporting means, inlcuding first means movably securing said one end panel to one of said two support members, permitting movement of said one end panel between said two spaced positions.
Claim 2
Dependent Claim
252 words
An educational module comprising: a generally horizontally positioned writing panel having a near edge presented adjacent a seated user, a rear edge, and two end edges connecting said near and rear edges, wherein intersections of said two end edges and said rear edge define first and second writing panel corners; supporting means for said module, including at least two upright support members which extend from a support surface to a point above said writing panel, said two support members being positioned adjacent said first and second writing panel corners; vertical panel means partially enclosing said writing panel, said vertical panel means being supported adjacent said end edges and said rear edge of said writing panel, said vertical panel means extending from a point below said writing panel to a point above said writing panel at least to head level of the seated user, said vertical panel means including two end panels supported adjacent said end edges, at least one of said two end panels being movable between two spaced operative positions without disturbing the structural integrity of the module, one of said two spaced positions being adjacent one end edge of said writing panel, the other of said two spaced positions being relatively away from said one end edge of said writing panel; and means securing said vertical panel means to said supporting means, inlcuding first means movably securing said one end panel to one of said two support members, permitting movement of said one end panel between said two spaced positions.
Claim 3
Dependent Claim
81 words
The module of claim 1, wherein the other of said two end panels is movable between two spaced operative positions from adjacent said other end edge of said writing panel to relatively away from said other end edge without disturbing the structural integrity of the module, and wherein said securing means includes second means movably securing said other end panel to the other of said two support members, permitting movement of said other end panel between its two spaced operative positions.
Claim 4
Dependent Claim
37 words
The module of claim 2, wherein said first and second means movably securing said end panels include means positioned at said first and second writing panel corners for rotatably supporting said one and said other end panels.
Claim 5
Dependent Claim
71 words
The module of claim 1, wherein the near edge of said writing panel is concavely shaped, the rear edge is convexly shaped, wherein the end edges of said writing panel intersect the rear edge thereof at substantially a 90° angle and converge toward the near edge thereof and each other at substantially a 90° angle, and wherein said supporting means are positioned only along said rear edge of said writing panel.
Claim 6
Dependent Claim
66 words
The module of claim 1, including horizontal bracing members secured to each of said two support members positioned adjacent said first and second writing panel corners, said horizontal bracing members, respectively, being secured to said two support members in the vicinity of, and such that they rest upon, said support surface when the module is in an operative position, thereby providing additional stability to the module.
Claim 7
Dependent Claim
20 words
The module of claim 1, including a stop means for stopping said one end panel in said other spaced position.
Claim 8
Dependent Claim
