Abstract
Abstract A wall is comprised of a plurality of parallel panels attached to a common support and spaced apart to define a slot therebetween for receiving a portion of a hanger. Each panel is a metal extrusion with a recessed central portion and a discrete substrate removably attached to the panels. Each panel central portion has a U-shaped channel with threads on opposite walls of the channel to facilitate coupling of the panels to the common support.

Claim 1
Independent Claim
114 words
A wall structure comprising a plurality of parallel panels attached to a common support and spaced apart to define a slot therebetween for receiving a portion of a hanger, each panel being a metal extrusion with a recessed central portion, a discrete substrate removably attached to side edge portions of said panels, each substrate overlying the recessed central portion of its associated panel, each panel central portion having a U-shaped channel on a rear face thereof, each channel having an end wall adjacent the substrate on its associated panel and generally parallel side walls, said channel side walls having threads along their length for receiving a threaded fastener at any location along their length.
Claim 2
Dependent Claim
114 words
A wall structure comprising a plurality of parallel panels attached to a common support and spaced apart to define a slot therebetween for receiving a portion of a hanger, each panel being a metal extrusion with a recessed central portion, a discrete substrate removably attached to side edge portions of said panels, each substrate overlying the recessed central portion of its associated panel, each panel central portion having a U-shaped channel on a rear face thereof, each channel having an end wall adjacent the substrate on its associated panel and generally parallel side walls, said channel side walls having threads along their length for receiving a threaded fastener at any location along their length.
Claim 3
Dependent Claim
20 words
A wall structure in accordance with claim 1 wherein said end wall engages a central portion of the associated substrate.
Claim 4
Dependent Claim
27 words
