Abstract:
A rail and supports therefor comprisingan elongated rail having an axis, an undercut groove of a uniform generally â€œCâ€  shape in cross section extending axially along the rail, and a plurality of supports attached to the rail in spaced-apart relation, each support including a bracket member having a supported surface adapted to engage a structure on which the rail is mounted and having a supporting surface spaced apart from the supported surface, a lock member received on the supporting surface of the bracket member, the lock member having a locking cam portion received in the undercut groove, the locking cam portion having a size and shape such that it can enter the undercut groove when it is in an unlocked rotational position relative to the undercut groove and such that it frictionally engages walls of the undercut groove in a locked rotational position relative to the undercut groove and thereby retains the rail against displacement relative to the structure, and a fastener joining the lock member to the bracket member against displacement of the lock member relative to the bracket member and for rotation of the lock member relative to the bracket member.
