  • Patent number: 5155962
    Abstract: A ceiling runner comprised of an elongated generally U-shaped channel member having longitudinally spaced openings in its web, each with one end portion shaped and sized to confine a transversely arranged upright C-stud therein. The remainder of the opening is of such size and shape as to permit the C-stud to be initially inserted therethrough with the web of its cross-section extending longitudinally of the web of the channel member and to be thereafter twisted about its longitudinal axis to a relatively transverse position to snap into place within said end portion, the web of the channel member having a retaining tab at one side and a detent and camming surface at the opposite side of the opening to cause the C-stud to flex sufficiently to snap into said end portion and to retain the C-stud within said end portion once it has snapped into place.
