Folding desk-bed

The blue desk is ready for use when the bed gets into vertical position. In the horizontal position of the bed the blue desk is hidden. There are two parallelogram mechanisms: The first of orange conrods keeps the desk always horizontal. The second of violet conrods keeps the brown legs always vertical. The blue sliding L-shaped pin locks the bed in its vertical position. STEP files of this video: Inventor files of this video: http:/
