  • Patent number: 4295315
    Abstract: An expansion joint cover comprises a pair of elongated rigid frame members, each of which includes a generally vertical, longitudinally continuous wall portion and a multiplicity of longitudinally spaced-apart, substantially horizontal plate-like tongues supported in cantilevered relation from the vertical wall portion at locations spaced from the upper edge of the wall portion and in longitudinal alignment. The longitudinal spacings between adjacent tongues of each frame member are not less than the widths of the tongues of the other frame member such that in the cover as installed in the expansion gap the tongues of each frame member project into the spaces between the tongues of the other frame member, and a generally longitudinally continuous bridge is formed by an intervening of the tongues of each of the frame members between the tongues of the other.
