Abstract

A BI-FOLD WOODEN FUTON FRAME (10) FEATURES A FORCE SPREADING MORTISE PLATE (66) POSITIONED AT A JUNCTION BETWEEN VARIOUS WOODEN MEMBERS, WHICH ARE HELD TOGETHER BY FASTENERS (45) SUCH AS SCREWS, THAT FORM THE FUTON FRAME. THE FORCE SPREADING MORTISE PLATE INCLUDES A MORTISE MEMBER (68) AND A HOOK MEMBER (70) EXTENDING TRANSVERSE TO THE MORTISE MEMBER. THE MORTISE MEMBER IS DISPOSED PROXIMATE TO A JUNCTION (54A, 54B, 54C, 54D), BETWEEN A PAIR OF THE WOODEN MEMBERS, AND THE HOOK MEMBER EXTENDS ADJACENT TO ONE OF THE PAIR. A FIRST PLURALITY OF FASTENERS EXTEND THROUGH THE PAIR OF WOODEN MEMBERS SO AS TO PASS THROUGH THE MORTISE MEMBER. A SECOND PLURALITY OF FASTENERS EXTEND THROUGH THE HOOK MEMBER AND INTO ONE OF THE PAIR OF WOODEN MEMBERS. IN THIS FASHION, FORCES EXERTED UPON BOTH THE FIRST AND SECOND PLURALITY OF FASTENERS ARE DISTRIBUTED BETWEEN THE MORTISE MEMBER AND THE HOOK MEMBER, THEREBY REDUCING THE FORCE PER UNIT AREA ON EACH OF THE PAIR OF WOODEN MEMBERS.
