Abstract
A panel locking device for assembling and interlocking two double wall panels along their adjoining edges structurally integrates the locking device within the two panels and retains the panels tightly locked together under tension under all conditions of subsequent thermal expansion and contraction. The locking device incorporates a locking pin which is driven through a lug and over a channel. Each panel has a perimeter frame. One edge of the perimeter frame of one panel forms a male channel, and the adjoining edge of the perimeter frame of the other panel forms a female channel. A lug is connected at one end to the web of the male channel. The outer end of the lug has a pin receiving and panel aligning hole extending through the lug. The web of the female channel is formed with a lug receiving slot extending through the web. An aligning and locking pin has a tapered tip; and when the panels are aligned edge-to-edge, the hole in the lug extends far enough above the backside of the female channel web to permit entry of the tapered tip of the pin. As the pin is driven into the hole and up to the full diameter of the pin, the lug is pulled upward through the slot in the female web. This produces elastic deflection of the male and female webs to retain the panels tightly locked together and structurally integrates the locking device into the perimeters of the two panels. The stressed deflection of the webs thus provides a constant and permanent force which urges the two panels together in tightly locked engagement.
