Abstract: A fastening assembly fastens adjacent sheet metal panels together along adjacent longitudinal edges. One of the panels has a first raised edge comprising a male locking member including an upstanding portion, a downturned end, and a continuous bulge extending outwardly from the downturned end. The other of the panels has a second raised edge comprising a female locking member including an upstanding portion parallel to the male locking member upstanding portion; a downturned portion parallel to the male locking member downturned portion; and an inwardly turned flat portion abutting a bottom portion of the bulge of the male locking member and providing locking interfering therewith. Sealing means are disposed between the male and female members, and the female locking member also includes a backturned end portion including a curved portion at the backturn thereof.

Abstract: A standing seam roof, including a particular clip for attaching the roof panels to building purlins. The clips are disposed at spaced points along the purlins and attach the panels to the roof along first and second raised generally longitudinally extending edges thereof. The clip includes portions extending under both of the panels at the edges thereof to provide vertical support to the roof and hold the panels above the purlins to provide for more efficient use of insulation between the panels and supporting members. Each clip preferably includes a base member and a tab member, the tab member slideable in an elongated opening in the base member to provide for free expansion and contraction of the roof panels. The base member includes a central upstanding portion with panel supporting portions extending from the top thereof in a plane perpendicular to the central upstanding portion. The elongated opening for the tab member is formed in the central upstanding portion.

Abstract: An elongated cap is provided which is utilizable in wall panel and standing seam systems for performing various fastening and protecting functions. The cap cooperates with a pair of clip arms extending upwardly from a body portion, and operatively attached to a panel or at a junction between panels, of a system with which the cap is associated. The cap includes a first end which is looped around a first flange extending perpendicularly to one of the clip arms, and the second end of the cap is pivoted about the interconnection between the first end and the first flange. A second flange is provided extending parallel to the first flange and outwardly therefrom, and is connected to the other of the clip arms. A second end of the cap, opposite the first end, is formed to provide an inwardly directed cam, and resiliency is provided in the assembly.
