摘要

A device for automatically increasing the surface of dining tables, consisting essentially of two boards joined by their edges by a strip of flexible leather so that they can be opened and closed; by a rod-axis, provided at each end with a square that holds the aforementioned bar on one of its sides and on the other, they are screwed to the frame bar of the table; by a lag screw that attaches the brackets to the frame and allows this and the shaft-bar to rotate, describing an eccentric by a fixed and glued piece that supports the weight of the two boards.
