Abstract
To realize a mechanism that can support an article at a desired position in such a way as to be able to move the article, with a thin, simple configuration.A load support mechanism 1 includes a fixed support section 2, which includes a fixed cam 8; a movable support section 3, which receives a load and can move vertically; a horizontal cam groove 13, which is provided in the movable support section; a cam follower member 15, which can move horizontally along the cam groove; a first spring 4, which is mounted between the fixed support section and the movable support section to support a load; and a second spring 18, which pushes the cam follower member horizontally and presses the cam follower member against a fixed cam surface 9 of the fixed cam. A reaction force of the fixed cam against the cam follower contains a vertical component depending on a height position of the movable support section, and the vertical component assists or reduces the spring's force to push up the load. A cam shape of the fixed cam surface is provided in such a way that the load acting around the cam follower, the spring forces of the first and second springs, and the reaction force applied from the fixed…
