FOLDABLE ENGINEERING DESIGN Russian patent published in 2023 - IPC F16H21/02 B25J11/00 

FIELD: architecture; mechanical engineering.

SUBSTANCE: used in the development and design of automated prefabricated structures. The folding engineering structure includes a rack and a platform, between which kinematic chains are installed, which include levers and connecting rods. Each kinematic chain is equipped with a screw made with right and left threads of equal pitch and coupled to the stand through rotary hinges, and two sliders coupled to the stand through translational hinges, and to the screw through screw hinges. Small rocker arms are installed between the levers and the stand using rotational hinges, and large rocker arms are installed between the connecting rods and the stand using rotational hinges, while rods are installed between the levers and the connecting rods using rotational hinges. The hinge axes between the screw and the stand, as well as the sliders and the stand and the sliders and the screw are orthogonal to the axes of the remaining hinges.

EFFECT: implementation of new functional properties of the device is ensured.
