Claim:
A device serving as a mezzanine fold-away bed, comprising: a support structure ( 10 ) having a pivot ( 33 ) and equipped with at least one frame ( 20 ), and a fold-away mechanism ( 30 ) configured to fold the frame ( 20 ) from a first use position ( 20 b ) to a second stow-away position ( 20 a ), the fold-away mechanism ( 30 ) comprising two shafts ( 31 ) mounted on the frame ( 20 ), each of these shafts ( 31 ) being linked by a tie-rod ( 32 ) to the pivot ( 33 ) on the support structure ( 10 ) to link the frame ( 20 ) to the support structure ( 10 ), the fold-away mechanism ( 30 ) also comprising a synchronizing mechanism configured to synchronize a movement connecting the two shafts ( 31 ) and to impose a synchronized rotation on the two shafts ( 31 ), wherein the synchronizing mechanism comprises a first element ( 34 ) connected to each shaft ( 31 ) and second elements ( 35 ) kinematically connecting external ends of the first elements ( 34 ) to stabilize the synchronized movement of the shafts ( 31 ), and wherein each of the first elements comprise a small tie-rod ( 34 ) provided on each shaft ( 31 ), the second elements comprise arms ( 35 ) configured to articulate the tie-rods ( 34 ), and the arms ( 35 ) and the tie-rods ( 34 ) define a deformable parallelogram configured to impose a synchronized rotation upon the two shafts ( 31 ).
