Abstract
Abstract A collapsible desk and chair formed of paperboard, cardboard or the like. The desk is formed from a plurality of blanks which are secured together to provide a unitary construction. The connected blanks define a top member, a pair of side support members and an inner shelf member which can be folded together into a relatively flat configuration for storage, and which can be unfolded and erected to define a desk having a pivotable top member and inner and side shelves for storage. The chair is formed from a base member blank and a seat member blank which are secured together to provide a unitary construction, and a separate inner support member formed of a single blank. The seat member is pivotally connected to the base member, and the separate inner support member is foldable and receivable within the erected base member for the purpose of reinforcing it and is supported by connected foldable flaps on the lower portion of the base member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
294 words
A collapsible desk comprising: a pair of collapsible side support members, each having a front and a rear end panel which are movable toward each other when the side support member is collapsed, each of said side support members also comprising side panels separated from said front and rear end panels by fold lines such that each side support member can be erected with said side panels in substantially perpendicular relation to said end panels; a first shelf member pivotally connected to the upper portion of the front end panel of each of said side support members for movement between a first position wherein said shelf member is substantially perpendicular to said front end panels and a second position wherein said shelf member is adjacent and substantially parallel to said front end panels; one of said side panels of each said side support members comprising a flap at the upper end thereof which is foldable toward the other side panel to provide a support for said shelf member when it is in said first position; and a top member pivotally connected to the upper portion of the rear end panel of each of said side support members for movement between a closed position wherein said top member extends across and is supported by the upper portions of said side support members and is substantially perpendicular to said rear end panels and an open position wherein said top member is adjacent and substantially parallel to said rear end panels; whereby when said shelf member is in said second position and said top member is in said open position, the desk can be collapsed to a substantially flat configuration by collapsing said side support members to move said front and rear end panels toward each other.
Claim 2
Dependent Claim
294 words
A collapsible desk comprising: a pair of collapsible side support members, each having a front and a rear end panel which are movable toward each other when the side support member is collapsed, each of said side support members also comprising side panels separated from said front and rear end panels by fold lines such that each side support member can be erected with said side panels in substantially perpendicular relation to said end panels; a first shelf member pivotally connected to the upper portion of the front end panel of each of said side support members for movement between a first position wherein said shelf member is substantially perpendicular to said front end panels and a second position wherein said shelf member is adjacent and substantially parallel to said front end panels; one of said side panels of each said side support members comprising a flap at the upper end thereof which is foldable toward the other side panel to provide a support for said shelf member when it is in said first position; and a top member pivotally connected to the upper portion of the rear end panel of each of said side support members for movement between a closed position wherein said top member extends across and is supported by the upper portions of said side support members and is substantially perpendicular to said rear end panels and an open position wherein said top member is adjacent and substantially parallel to said rear end panels; whereby when said shelf member is in said second position and said top member is in said open position, the desk can be collapsed to a substantially flat configuration by collapsing said side support members to move said front and rear end panels toward each other.
Claim 3
Dependent Claim
21 words
The desk of claim 1 wherein said side support members, said shelf member and said top member are formed of paperboard.
Claim 4
Dependent Claim
62 words
The desk of claim 1 wherein said other side panel of each side support member comprises a cut-out portion and a second shelf member pivotally movable in said cut-out portion, said second shelf member being movable between a first position in substantially parallel relation to said one side panel and a second position in substantially perpendicular relation to said one side panel.
Claim 5
Dependent Claim
47 words
The desk of claim 3 wherein said second shelf member of each side support member comprises a tab on the outer edge thereof, and said one side panel comprises a slot adapted to receive said tab when said second shelf member is disposed in said second position.
