Patent ID: 8176583

Claim:
A siderail assembly for a bed comprising: a link (P) pivotably connectable to a bed frame at a joint (PF) and to a rail at a joint (PR), the link (P) being pivotable relative to rail about a first pivot axis, the link (P) having at least one reaction surface; a link (Q) having a frame end and a common end, the frame end being pivotably connected to the frame at a joint (QF); a link (R) having a rail end and a common end, the rail end being pivotably connected to the rail at a joint (RR), the common ends of the link (Q) and the link (R) being pivotably connected to each other at a joint (A) by an element that extends parallel to the first pivot axis, the element being constrained to move substantially parallel to the reaction surface while engaging and moving along the reaction surface as the links (P), (Q), and (R) pivot during movement of the rail between deployed and stowed positions, the links (Q) and (R) folding about joint (A) during movement of the rail toward the stowed position and unfolding about joint (A) during movement of the rail toward the deployed position.
