ABSTRACT:
An expansion joint for joining first and second adjacent segments of direct glue down carpet mounted on respective underlying adjacent first and second floor segments. A first subchannel is mounted in the first floor segment along a joint line of the adjacent first and second carpet segments and a second subchannel is mounted in the second floor segment along the joint line of the adjacent first and second carpet segments in parallel relative moveable relation to the first subchannel. A first cover supports the first of the carpet segments on the first subchannel and a second cover supports the other of the adjacent carpet segments on the second subchannel. A tension bar is positioned in the second subchannel for movement to and from the first subchannel, the tension bar for holding the free edge of the first carpet segment under tension during relative movement between the first and second subchannels thereby allowing expansion and contraction of the adjacent first and second floor segments without stretching or buckling of the overlying direct glue down carpet segments.
