Interference No. 103,611 that when the sofa bed was in the folded or sofa position, the deck would yield in a downward direction to provide seating comfort but not yield in an upward direction to prevent the mattress from bowing upward in a convex shape causing an upward bulge of the sofa cushions. In the unfolded or bed position the deck would not yield in a downward direction to provide the desired support for the mattress. During the dinner, Miller disclosed to Holobaugh various forms of his deck. One form of the deck included rows of plastic members having recesses and projections in the opposite ends thereof so that the projections of one plastic member would mate into the recesses of an adjacent plastic member in end to end relationship. A hinge pin extended through the mating ends of the plastic parts to interconnect the parts for pivotal movement relative to each other. The plastic parts were provided with stops on the opposite ends thereof so that a stop on one plastic member would be engaged with a stop surface on the adjacent plastic member to prevent pivotal movement in one direction but to allow pivotal movement in the opposite direction. Miller Exhibit C is a napkin bearing a sketch made during the dinner showing the plastic members.
