  • Lifting mechanism for liftable side rails for a lying table such as a bed
    Patent number: 6691345
    Abstract: The pair of support arms connected with the respectively horizontal both sides of the plural side rail members lift and lower the side rail proper consisting of a plurality of side rail members by the pivotal rotation of the support arms along the pivotally rotational loci between the high service position and the low stored position. In this motion, the connection points between the support arms and the side rail members are disposed in such a manner that the connection points of the upper side rail member make pivotally rotational motion relatively delayed in phase, with the connection points of the lowest side rail member as the fulcrums, when the side rail members are moved to descend by the pivotally rotational motion of the support arms.

  • Liftable side rail for a lying table such as a bed
    Patent number: 6564404
    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.
