ABSTRACT:
A three element pivot bearing for wood frame wall bed systems includes a spindle having an anchoring tang at one end perpendicular to its axis and two cylindrical bearing bushings each with an annular collar at one end journaled around the spindle with the annular collars facing each other. One bearing bushing is received in a hole drilled into/through a wood side frame of a mattress pallet for a wall bed with its annular collar facing out. The other bearing bushing extends into a hole drilled into-through a wood vertical side support of the wall bed with its annular collar facing in. The spindle extends through either the wood side frame of the mattress pallet or wood vertical side support of the wall bed into the respective bearing bushings with its anchoring tang secured to either of the side frame of the mattress pallet or vertical side support. Conical head screws received in countersunk holes drilled through the collars and spindle tang secure the respective bearing elements to the respective wood frame members.
