Device for convertible sofa beds, essentially characterized by comprising two pieces in the form of a metal plate cassette, with preferably rectangular larger sides, provided with four perforated tabs arranged two by two, by means of which they are articulated to the interrupted beams of each side of the frame of the mattress, joining them to allow their articulation carrying each one of said boxes a part integral with them, with an axial perforation that serves as a guide to the sliding of a latch housed in it whose latch is hingedly joined one end to a plate that it acts as a connecting rod, to which end the other end is articulated to one of the parts of the stringer of the bed frame, so that when passing from the sofa to the bed position, said rod drives the latch which penetrates the end of the tube that constitutes the other part of the stringer of the frame of the bed frame, with which both parts remain anchored and rigid united by means of the box and its latch, making legs or intermediate supports unnecessary in the center.
