<p>SEAL-ACTUATING MECHANISM FOR A WALL PANEL A seal-actuating mechanism, which when mounted in a wall panel of the type having channel-shaped opposed frame members can be installed, replaced or repaired without removing the exterior finished surface of the wall panel. The sealactuating mechanism includes a rotatable shaft mounted between the opposed frame members and an operator member including pivot lever means is mounted on each end thereof. At least one tension member is disposed in the cavity of each frame member, one end of which is coupled to the pivot lever means, and the other end is coupled to the shiftable seal assembly so that when the shaft is rotated the seal assembly is shifted respectively from an extended unlatched position to its retracted latched position.</p> |
