Abstract
Abstract A three-section portable partition has identically shaped vertical posts formed with continuous slots for adjustably mounting appurtenances and also to provide a unique interlock with transverse panels for exceptional panel rigidity. The partition sections are hinged at adjacent vertically extending edges and are pivotable relative to each other about the vertical hinge axes between a fully folded storage position with the planes of the sections approximately parallel to an extended or operative position with the section planes intersecting at equal angles. H-shaped transverse frame members interconnect with the posts such that a one-piece key is readily insertable into and is hidden within the upwardly opening recesses of the top transverse members to lock the sections in the operative position. Lockable casters on the outside posts provide three-point support for the unfolded partition and a fourth caster on one of the inner posts is elevated slightly above the plane of the other three to give support when the partition is folded.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
237 words
A foldable partition adapted to stand vertically on a supporting surface and having a plurality of plane sections pivotably interconnected at adjacent vertical edges for relative movement between a folded position with the sections adjacent each other and an unfolded position with the sections angularly displaced from each other, each of said sections comprising: a panel; inner and outer vertically extending posts telescoped over the side edges of said panel; upper and lower transverse members secured at opposite ends to said posts and telescoped over the upper and lower edges, respectively, of said panel, said upper member having an upwardly opening passage traversing at least part of the upper end of the inner post; meaNs for securing said posts and said members to said panel, each of said posts having at least one vertically extending recess on the same side of the panel, and a caster secured to and projecting below the lower end of the outer post engageable with said supporting surface; a caster secured to the lower end of the inner post of one of said sections; and means for locking said sections in the unfolded position comprising a key having legs adapted to be disposed in the vertical planes of and intersecting at the desired angular displacement of said sections in the unfolded position and alignable with the inner posts and engageable with said upper members to limit relative pivotal movement of said sections.
Claim 2
Dependent Claim
237 words
A foldable partition adapted to stand vertically on a supporting surface and having a plurality of plane sections pivotably interconnected at adjacent vertical edges for relative movement between a folded position with the sections adjacent each other and an unfolded position with the sections angularly displaced from each other, each of said sections comprising: a panel; inner and outer vertically extending posts telescoped over the side edges of said panel; upper and lower transverse members secured at opposite ends to said posts and telescoped over the upper and lower edges, respectively, of said panel, said upper member having an upwardly opening passage traversing at least part of the upper end of the inner post; meaNs for securing said posts and said members to said panel, each of said posts having at least one vertically extending recess on the same side of the panel, and a caster secured to and projecting below the lower end of the outer post engageable with said supporting surface; a caster secured to the lower end of the inner post of one of said sections; and means for locking said sections in the unfolded position comprising a key having legs adapted to be disposed in the vertical planes of and intersecting at the desired angular displacement of said sections in the unfolded position and alignable with the inner posts and engageable with said upper members to limit relative pivotal movement of said sections.
Claim 3
Dependent Claim
32 words
The partition according to claim 1 in which said passages are open at their ends adjacent to the respective inner posts, said key being a one-piece bar-type element insertable into said passages.
Claim 4
Dependent Claim
73 words
The partition according to claim 1 in which each of said posts comprises a one-piece extrusion having a generally U-shaped cross section with a plane end wall and opposing sidewalls and spaced strips opposite said end wall, said sidewalls having opposed inwardly extending channel-shaped portions defining said vertical recesses, the space between said strips being approximately equal to the thickness of said panel whereby the latter extends into the post between said strips.
Claim 5
Dependent Claim
39 words
The partition according to claim 3 in which the space between said inwardly extending portions of the side walls is approximately equal to the panel thickness, and securing means extending through the inwardly extending sidewall portions into said panel.
Claim 6
Dependent Claim
41 words
The partition according to claim 3 in which said strips have lipped edges, and plates adapted to be disposed between said strips on parts of the post above and below said panel, said plates having interlocking engagement with said strip edges.
Claim 7
Dependent Claim
54 words
The partition according to claim 3 in which each of said transverse members is H-shaped in cross section and has outwardly extending legs defining said passage, the ends of said members extending into said outer and inner posts between the strips thereof, said members having slots therein for receiving the edges of said strips.
Claim 8
Dependent Claim
41 words
The partition according to claim 1 in which said panel is a laminar structure having a rigid centerboard and porous outer boards, said securing means comprising screws extending through the walls of said posts and of said members into said centerboard.
Claim 9
Dependent Claim
64 words
The partition according to claim 1 in which the outer post extends vertically from its junctions with said transverse members and the upper end of the inner post is flush with the upper member, the end wall of said inner post having an upwardly opening slot therein aligned with said passage in the upper member and dimensioned to receive a leg of said key.
Claim 10
Dependent Claim
119 words
The partition according to claim 1 in which each post has a pair of lips defining the opening of the vertical recess therein, in combination with a bracket adapted to be secured to each of said posts, said bracket having support plate and a brace member integrally joined in a T-shaped cross-sectional configuration, the junction of the plate and brace member having a longitudinal bore therethrough, an elongated bolt extending through said bore and projecting therefrom for insertion into said vertically extending recess of the post, and a nut disposable within said post recess and threadedly engageable with said bolt whereby to clamp said plate and brace element against the sidewall of the post when said bolt is tightened.
Claim 11
Dependent Claim
41 words
The partition according to claim 11 in which a rear edge of said brace member abuts said post within said vertical recess and a lower edge thereof inclines upwardly toward convergence with said plate in a direction outwardly from the post.
Claim 12
Dependent Claim
41 words
The partition according to claim 10 in which said nut has a parallelogram-shaped profile with a height less than spacing of the lips of the recess whereby The bracket is clampable to and unclampable from the post at any selected height.
Claim 13
Dependent Claim
34 words
The partition according to claim 1 with at least three of said sections, said caster on the inner post being spaced slightly above said supporting surface when said sections are in the unfolded position.
Claim 14
Dependent Claim
26 words
The partition according to claim 1 with accessory supporting bracket means insertable into said vertical recesses and releasably interlockable with said posts at selected elevations therealong.
