Abstract
Abstract A partition system including apparatus for joining movable wall partitions or panels comprising an elongated, cylindrical connector received in corresponding apertures formed in the edges of at least two partitions. The connector includes threaded apertures extending transversely thereof and spaced apart a predetermined distance such that one threaded aperture is in each partition. Threaded pins or bolts having tapered heads are received in each of said threaded aperture through slightly oversized, countersunk holes formed in one surface of each of said partitions and communicating perpendicularly with the apertures in said partition edges, said holes being on centers spaced slightly farther apart than the threaded apertures. Tightening said tapered heads into said counter-sunk holes wedges said partitions tightly and securely together forming a joint with a minimum of visible cracks.
