Abstract
Abstract An article of furniture movable between an erect position and a folded generally planar position is provided including a top planar supporting surface formed by two mating halves when the article is in its erect position. A first pair of braces are secured to the undersurface of one of the halves and extend in a direction normal to the line of mating of the halves and under the undersurface of the other of the halves to support the other of the halves when the article is in its erect position. A second pair of braces are spaced inwardly of the first pair of braces and are secured to the undersurface of the other of the halves and extend in a direction opposite to the first pair of braces and under the undersurface of the first of the halves to support the first of the halves when the article is in its erect position. Leg members for supporting the article in its erect position are pivotally secured to the free ends of the braces and cross on opposite sides of the top surface and are pivotally connected at their point of crossing. A bar is pivotally connected to the second pair of braces and the leg members pivotally connected thereto to provide both a support for the underside of the half having the first pair of braces secured thereto and a handle for carrying the article when it is folded into its generally planar position.

Claim 1
Independent Claim
387 words
An article of furniture movable between an erect position forming said article of furniture and a folded generally planar position for carrying said article comprising: a top member composed of two mating halves forming a planar supporting surface when said article is in its erect position; a first pair of elongated brace members fixedly secured at one end to the undersurface of one of said halves on each side thereof and extending in a direction substantially normal to the axis passing through the point of mating of said halves and the other end thereof extending along the undersurface of the other of said halves to generally the outer limit thereof to provide a support for the undersurface of the other of said halves when said article is in its erect position; a second pair of elongated brace members fixedly secured at one end to the undersurface of the other of said halves on each side thereof and spaced inwardly of said first pair of brace members when said article is in its erect position, said second pair of brace members extending in the opposite direction as said first pair of brace members and also substantially normal to the axis passing through the point of mating of said halves with the other end of each of said second brace members extending along the undersurface of the first of said halves to generally the outer limit thereof to provide a support for the undersurface of the first of said halves when said article is in its erect position; leg members for supporting said article when in an erect position pivotally connected to the free ends of each of said brace members, the pair of said leg members connected to the brace members on opposite sides of their respective halves crossing each other and being pivotally connected at their point of crossing; and means extending between the second pair of brace members at their other ends and pivotally connected to both said second pair of brace members and the leg members pivotally connected thereto for providing both a support for the underside of said half haVing said first pair of brace members fixedly secured thereto when said article is in its erect position and a handle for carrying said article when said article is in its folded generally planar position.
Claim 2
Dependent Claim
387 words
An article of furniture movable between an erect position forming said article of furniture and a folded generally planar position for carrying said article comprising: a top member composed of two mating halves forming a planar supporting surface when said article is in its erect position; a first pair of elongated brace members fixedly secured at one end to the undersurface of one of said halves on each side thereof and extending in a direction substantially normal to the axis passing through the point of mating of said halves and the other end thereof extending along the undersurface of the other of said halves to generally the outer limit thereof to provide a support for the undersurface of the other of said halves when said article is in its erect position; a second pair of elongated brace members fixedly secured at one end to the undersurface of the other of said halves on each side thereof and spaced inwardly of said first pair of brace members when said article is in its erect position, said second pair of brace members extending in the opposite direction as said first pair of brace members and also substantially normal to the axis passing through the point of mating of said halves with the other end of each of said second brace members extending along the undersurface of the first of said halves to generally the outer limit thereof to provide a support for the undersurface of the first of said halves when said article is in its erect position; leg members for supporting said article when in an erect position pivotally connected to the free ends of each of said brace members, the pair of said leg members connected to the brace members on opposite sides of their respective halves crossing each other and being pivotally connected at their point of crossing; and means extending between the second pair of brace members at their other ends and pivotally connected to both said second pair of brace members and the leg members pivotally connected thereto for providing both a support for the underside of said half haVing said first pair of brace members fixedly secured thereto when said article is in its erect position and a handle for carrying said article when said article is in its folded generally planar position.
Claim 3
Dependent Claim
39 words
The article of furniture of claim 1 wherein each of said pair of brace members extend along and are secured to their respective halves along generally the entire undersurface thereof from one side of said halves to the other.
Claim 4
Dependent Claim
