Abstract

Improvements in the construction of expandable furniture, characterized in that preferably referring to tables, these are constituted by the following elements in combination with each other: a variable number of vertical support legs; a fixed horizontal frame, supported by said legs; a horizontal frame, vertically displaceable, located on the previous one, and with which it is related by as many pairs of arms as vertices possess, each pair of said arms being articulated to each other, and with both frames; like scissors; a set, as a minimum, of levers for fixing the upper frame when it is in an elevated position, consisting of one arm articulated at one end near a vertex of the upper frame, and another articulated arm, also at one end, at an intermediate point of the arm of the corresponding vertex of the lower frame, both being articulated by their free ends and from this point, by means of a connecting rod, to a point of the lower frame; two boards of the same geometric shape, articulated with each other and susceptible, both to extend one after another, and to refute one over another; a box disposed eccentrically in the upper frame, and in which the lower board is articulated, and a circular guiding path, also integral with the upper frame whose center of curvature coincides with the geometric axis of the frame, and on which it is susceptible slide the lower board by turning around the frame, in order to adopt the most suitable position to the relative situation that you want to communicate to both boards, holding on to that path with a staple, at least.
