Abstract

1276126 Vertically adjustable bed J N J VAN DER MEIJ 19 Sept 1969 46275/69 Heading A4J The vertical adjustment is powered by linnon springs 12, 13 acting on a sector plate 9 pivoted at 30, spring 12 having a fixed point 17 of application and spring 13 being secured to a block 14 adjustably slidable in an arcuate track 15 between extreme positions when it completely opposes, or augments, the other spring. Thus the effective spring force (which is applied to urge the bed upwardly) may be varied. This is done by windlass arrangement 26 and cable 19.
