in their assembled state.

Descr ption

  The present invention relates to a convertible sofa bed.

  This sofa bed is made up of two parts, a fixed part (2) and (3) and a mobile part (1).

  The fixed part is placed on two U-shaped legs. This leaves the mobile part free, which can thus pivot for

do a full rotation.

  The two parts (mobile and fixed) are completely independent of each other. Such a convertible sofa bed has the advantage of being of a simple structure, and of a simple and rapid implementation to pass from the sofa structure to the bed position. The object of the invention is to provide a sofa convertible bed quickly, without the extra bulk that

that of the sofa.

  To this end, in the sofa bed concerned, the fixed part has notches at each of its high internal edges

  allowing the assembly of the mobile part composed of the seat and its back and a mattress.

  In practice, when the sofa bed is in the sofa position and you want to transform it into a bed, you just have to fold the backrest onto the seat by pivoting it forward

  A simple closing system allows the backrest to be fixed to the seat.

  i5 It is now necessary to lift the movable part before until studs fixed on the movable part of the sofa bed come out of the notches located on the fixed parts of the sofa bed Pull the movable part towards you using the guide located on the fixed parts of the sofa until the system is blocked by

to a stop.

  At this time, rotate the movable part of the sofa backwards until you get the bed position.

  The fixed part (2) and (3) is made up of two transverse U-shaped legs (3) on which two U-shaped guides (6) are placed. Figure 2: the tenons of the movable part (I) allow the link with the fixed part by a link

  IO A fixing (i O) prevents the opening of the backrest when transforming the sofa into a bed To allow the rotation of the movable part (i), the pins (7) fixed on it are held in the guides (6 ) of the fixed part (2). 4 notches located on the upper part of the guides (6) and of the fixed part (2) allow the studs (0 to be released.

This translation is obtained by the U-shape of the guides (6). Then tilt the movable part (I) towards the rear of the sofa bed to allow the studs to enter

(7) in their notches (5).
