<p>. Improvement in mounting means. A combination of first and second plates adapted to sandwich between them a panel to which they are to be affixed. The first plate has at least one boss projecting from one face thereof, and first threaded means spaced from the boss. The boss defines a lip spaced from the face, at least part of the lip being directed generally toward the first threaded means. The second plate defines a first edge adapted to be received under the lip, and a second edge adapted to lie adjacent the first threaded means. The combination further includes a second threaded means for engagement with the first threaded means, the second threaded means having a portion adapted to bear against the second edge of the second plate.</p> |
