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 in…
