Pivot bearing for wood frame wall bed systems

In a wood wall bed system including a wood mattress frame comprising a mattress pallet and side frames, said frame coupled to and supported near its head end between wood side walls of a standing frame structure for rotation about a pivot axis between a horizontal sleeping position and a vertical storage position between the walls of the standing frame structure;

• a pair of improved pivot bearings for coupling the mattress frame and standing frame structure, each comprising,
• a cylindrical spindle having a tang at one end extending perpendicular to its axis,
• two cylindrical bearing bushings each having an annular facing collar at one end presenting
• an annular facing surface dimensioned to journal around the spindle, and
• securing means for anchoring the tang of the spindle,
• wherein one bearing bushing of each pivot bearing is secured in a hole axially aligned with the pivot axis drilled into an inside surface of each side wall of the standing frame structure with the annular facing collar of the bushing facing in, and the other bearing bushing of each pivot bearing is secured in a hole axially aligned along a common axis drilled through each side member of the mattress frame near its head with the annular facing collar of the bushing facing out, and
• wherein the cylindrical spindle of each pivot bearing is received in a cylindrical passageway created by adjacent bearing bushings upon coaxially aligning the bearing bushings secured in the side frame members of the mattress frame with the pivot axis of the wall bed system for pivotally coupling the particular side frame members of the mattress pallet to the adjacent side wall of the standing frame structure with the annular facing collars of adjacent bearing bushings in a facing relationship, the securing means anchoring the extending tangs of the respective spindles to the side members of the mattress frame.
