Similarly, asecond end 377 ofbase 370 is pivotably coupled to the lower ends offlanges 354 offirst link 344 by arod 378. Thus,linkage assembly 342 provides a four barlinkage permitting siderails - As previously stated,
linkage assemblies 342 are fixed to theintermediate frame 52 such thatlongitudinal axes 343 oflinkage assemblies 342 are not perpendicular to a plane defined byintermediate frame 52. Therefore, assiderails directions Second links 346 andfourth links 350 rotate aboutrods 358, 378. As shown in FIG. 8,rods 358 and 378 each have an axis ofrotation rotation 345 forlinkage 342. The overall axis ofrotation 345 has a vertical component indirection 393 parallel withvertical axis 396 and a longitudinal horizontal component indirection 324 parallel withlongitudinal axis 398 ofrail member 340. Therefore, axis ofrotation 345 is not parallel with or perpendicular tolongitudinal axis 398 ofrail member 340 at any time whenrail member 340 is stationary or during movement between the raised and lowered positions. Further, whenmattress 13 is in a flat bed position, as shown in FIGS. 6 and 7, axis ofrotation 345 is not horizontal. - Each

A patient-inaccessible release or handle 392 is provided that is coupled tosecond end 390.First end 388 includes anotch 394 configured to receivecatch rod 386 therein to securelatch member 382 in the latched position as shown in FIG. 8. - When
first end 388 is latched ontocatch rod 386, a three bar linkage is established betweenfirst link 344,latch member 382, andfourth link 350. This arrangement of linkages bindsfirst link 344 relative tofourth link 350 so thatlinkage assembly 342 is also bound from moving whilelatch member 382 is in the latched position to preventsiderails - As previously discussed, when siderails320, 321 swing into the lowered position, the downward movement is accompanied by longitudinal movement as shown in FIGS. 6 and 7. The longitudinal movement associated with downward movement for
head end siderail 321 is typically towardsheadboard 16 indirection 324 without any return movement indirection 326. Preferably, downward movement forhead end siderail 321 is associated with longitudinal movement towards theheadboard 16 indirection 324. The longitudinal movement associated with the downward movement offoot end siderail 320 is typically towardfootboard 18 indirection 326. Preferably, similar tohead end siderail 321, all downward movement thefoot end siderail 320 is associated with longitudinal movement towards thefootboard 18 indirection 326 without any return movement indirection 324.
