Abstract
A liftable side rail for a lying table such as a bed, comprising a side rail proper, being pivotally rotatably connected with a pair of support arms pivotally rotatably supported at side rail installation points of the lying table, to be supported in such a manner that the side rail proper may be lifted and lowered by the pivotally rotational motion of these support arms along the pivotally rotational loci between an upper service position and a lower stored position, and each of the support arms, having protrusions functioning as auxiliary side rail members on both sides of the straight line connecting said installation point and the connection point with the side rail proper.When the side rail is held at the lower stored position, the protrusions provided for the support arms are placed along the side rail proper without protruding above and below. So, the tops and bottoms of the protrusions do not constitute any obstruction. Therefore, even if the lying table is low in the height of the deck, the distance between the bottom of the side rail proper and the floor surface can be kept large.
