Intersection construction for movable wall panel system

Claim 1

In a movable wall panel system which includes a plurality of tracks having parallel spaced-apart side walls and parallel spaced-apart running surfaces defining slots therebetween, a series of movable wall panels, and means for movably suspending said wall panels from said tracks, wherein the ends of said running surfaces are disposed at right-angles mutually adjacent to each other, the combination comprising interlock means including lateral flanges spaced below said running surfaces and defining gaps therebetween, and a plurality of intersectionforming inserts for connecting said mutually adjacent tracks together, each insert including an intermediate corner-forming body and a pair of arms extending outwardly at right angles from said body for insertion into said gaps, said body including pairs of abutment surfaces for mating against adjacent running surfaces and for mating against adjacent lateral flanges, a vertical stemlike portion having an arcuate cross-section with abutment surfaces for mating against said side walls, upper surfaces coplanar with said running surfaces, and pairs of generally vertical surfaces forming extensions of said slots and converging to form an intersection corner for conveniently assembling said tracks in a grid.
