Bedding assembly raising device, has connecting rods controlled by electromechanical jack and articulated on fixed lower frame and on movable upper frame, respectively, to articulate frames with respect to each other

摘要

The device has a fixed lower frame remaining at ground, and a movable upper frame receiving a bedding assembly, where each frame has two parallel side rails (A, B). Connecting rods (F1, F2) forming a deformable parallelogram are controlled by an electromechanical jack and articulated on the lower frame at articulation points (J, L) and upper frame at articulation points (I, K), respectively, to articulate the frames with each other.
