Structural member and assembly thereof

Abstract

A structural member for use in forming frames by having connected thereto an associated member carrying a mounting stud having a shank with an enlarged head thereon, the structural member including a plurality of clover-leaf shaped holes in alignment therealong for receiving the mounting stud, each of the holes including four cusps arranged therearound with the edges of adjacent cusps joined by concave surfaces, at least one of the concave surfaces extending downwardly with the associated cusps disposed generally horizontally when the structural member is in its operative position, the cusps each having a generally vertically oriented straight side with opposed ones of said straight sides being joined by one of the concave surfaces at the bottom ends thereof, the straight sides converging toward the associated concave surface and being spaced apart at the points of the cusps a first distance slightly less than the diameter of the shank of the associated stud with the points of the cusps being spaced from the farthest point on the associated concave surface a second distance greater that the radius of the shank of the associated stud; there also is provided an assembly including first and second structural members and a snap lock to hold the mounting stud in the associated clover-leaf shaped hole, and to make sure the associated stud is properly seated in the clover-leaf shaped hole.
