Abstract
Abstract A sound and visual partition screen panel utilizes a treated corrugated cardboard septum to which is secured a frame. Acoustic insulation pads are provided on each side of the septum within the frame. The frame is designed with rounded vertical and top edges which are adapted to receive a fabric covering in the form of a sewn sock or sleeve which includes seams with inwardly formed welts adapted to be threaded into recesses in the verticals which open to the edges of the panels through a very narrow slot. The top and bottom of each vertical is provided with a removable pin, the one on the bottom also adjustably supporting the panel, which pins in turn secure plastic blocks having semi-circular gear segments, the gear teeth projecting just beyond the rounded surface of the verticals. The gear teeth extend for only slightly less than one half the height of the semi-circular face of the block. The blocks may be inverted by removing and replacing the pins. This presents the gear teeth at selected elevations to enable the formation of two, three or four way inter-panel connections. The gearing only at the same elevation will be in mesh enabling synchronous non-binding pivoting of the interconnected panels. A link through which the pins of adjacent panels extend holds the gearing in mesh. The top pin may be in the form of a clamp screw to lock the links in place. The panels, in addition to being interconnected, may be connected to walls, storage or filing cabinets, or when dividing work stations, to a power column with an ambient light serving those work stations. The power columns with panels attached form a low cost office layout.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
99 words
An interior office sound and visual screen having a central septum including top and bottom frame members, semi-circular extrusions secured at the top and vertical edges of said septum, said semi-circular extrusions being wider than the septum, semi-circular gears at the top and bottom of the vertical edge semi-circular extrusions, means to secure said gears to the septum, and half-dome covers for the gears at the top of the vertical edge semi-circular extrusions, said half-dome covers filling the upper corners of the screen between the vertical extrusions and forming a generally rounded corner surface continuation of the semi-circular extrusions.
Claim 2
Dependent Claim
99 words
An interior office sound and visual screen having a central septum including top and bottom frame members, semi-circular extrusions secured at the top and vertical edges of said septum, said semi-circular extrusions being wider than the septum, semi-circular gears at the top and bottom of the vertical edge semi-circular extrusions, means to secure said gears to the septum, and half-dome covers for the gears at the top of the vertical edge semi-circular extrusions, said half-dome covers filling the upper corners of the screen between the vertical extrusions and forming a generally rounded corner surface continuation of the semi-circular extrusions.
Claim 3
Dependent Claim
34 words
An interior office screen as set forth in claim 1 including sound absorbing material extending to the width of said extrusions on each side of said septum, and a fabric cover on said screen.
Claim 4
Dependent Claim
35 words
An interior office screen as set forth in claim 2 wherein each extrusion includes a slot at the center of its semi-cylindrical surface adapted to receive, secure and conceal an edge of said fabric cover.
Claim 5
Dependent Claim
55 words
An interior office screen as set forth in claim 1 wherein the teeth of said gears project just beyond said semi-circular extrusions and are adapted to mate with corresponding gears on adjacent screens, and removable link means adapted to be secured to said screen and interconnecting adjacent screens to hold said gears in meshing engagement.
Claim 6
Dependent Claim
26 words
An interior office screen as set forth in claim 4 wherein said removable link means includes a link extending between the centers of said meshing gears.
Claim 7
Dependent Claim
33 words
An interior office screen as set forth in claim 5 wherein said removable link means at the top of each screen extends between the top of the gear and the respective half-dome cover.
Claim 8
Dependent Claim
40 words
An interior office sceen as set forth in claim 6 wherein said link means are secured by a fastener, and said half-dome covers are plastic and include a snap-on, snap-off connection to the screen to conceal and expose such fastener.
Claim 9
Dependent Claim
183 words
A screen comprising a frame including verticals having semi-circular outwardly directed edges, and fastening means for securing the screen to an adjacent structure alternately fixed in one of a plurality of angular relationships with an adjacent structure or angularly movable with respect to an adjacent structure, the fastening means including link means projecting from the screen and pivotable about the axis of the semi-circular edges of the vertical for positioning the screen a fixed distance from an adjacent structure, a gear segment having teeth extending radially outward beyond the semi-circular edges of the vertical of the screen and adapted to engage with corresponding teeth on an adjacent structure, and means for positioning the gear segment in a selected one of two vertical positions in the first of which the teeth of the gear segment are coplanar with and engage corresponding teeth of an adjacent structure thereby to fix the angular relationship of the screen with an adjacent structure and in the second of which vertical positions the teeth of the gear segment are free of engagement with corresponding teeth of an adjacent structure.
Claim 10
Dependent Claim
183 words
A screen comprising a frame including verticals having semi-circular outwardly directed edges, and fastening means for securing the screen to an adjacent structure alternately fixed in one of a plurality of angular relationships with an adjacent structure or angularly movable with respect to an adjacent structure, the fastening means including link means projecting from the screen and pivotable about the axis of the semi-circular edges of the vertical for positioning the screen a fixed distance from an adjacent structure, a gear segment having teeth extending radially outward beyond the semi-circular edges of the vertical of the screen and adapted to engage with corresponding teeth on an adjacent structure, and means for positioning the gear segment in a selected one of two vertical positions in the first of which the teeth of the gear segment are coplanar with and engage corresponding teeth of an adjacent structure thereby to fix the angular relationship of the screen with an adjacent structure and in the second of which vertical positions the teeth of the gear segment are free of engagement with corresponding teeth of an adjacent structure.
Claim 11
Dependent Claim
15 words
The screen of claim 8 wherein the adjacent structure is another one of said screens.
Claim 12
Dependent Claim
24 words
The screen of claim 8 having a removable pin coaxial with the semi-circular edges of the vertical connecting the link means with the screen.
