    OBJECT OF THE INVENTION
    The present invention relates to a sofa bed whose configuration also allows to offer support for the legs and has an easy operation of configuration in bed and vice versa. BACKGROUND OF THE INVENTION
    At present, sofa beds of various types are known. One of them is configured by a structure that supports a double frame - seat and backrest-articulated by means of a sliding non-return ratchet, so that the backrest can be folded horizontally with the seat, sliding the joint until it reaches the center of the structure. On the set there is a fluffy body that offers support in both configurations. It has the disadvantage that the folding of the backrest increases the occupation backwards, requiring the separation of the structure from the wall at the time of transformation to bed and joining it when returning to the armchair configuration if the furniture is placed attached to a wall, which It is usually a very usual distribution. In addition, the arrangement of the joint in the longitudinal center of the bed impairs comfort just in the area of greatest use as a bed.
    Another configuration consists of a box spring articulated transversely in two or three sections, which by means of a complex mechanism assisted by springs or the like allows its rear and lower snooping in a drawer that structures the sofa. It has the disadvantage of mechanical complexity, that it is necessary to remove the cushions or pillows from the seat, which are the most bulky, and find them a location when the furniture is in a bed configuration, and that the mattress is usually very thin and uncomfortable as it must allow folding in the sofa configuration
    Another similar option widely used as companion beds in hospitals implements


    also a retractable mechanism with the help of springs inside the drawer that configures the furniture envelope, but without the bed base having to be folded or divided, and has the same drawback of requiring additional storage for the seat cushions when the furniture It is in bed configuration, and in addition the minimum depth of the furniture in sofa configuration is very large - occupying a larger and useless space in the room - or in counterpart to the width of the bed in the corresponding configuration is very small, since The unfolded bed base must fit inside the drawer that structures the sofa configuration.
    Other options - such as trundle beds - which, when not being occupied, also have the disadvantages of excessive seat depth, so the back cushions must be very deep. DESCRIPTION OF THE INVENTION
    The sofa bed of the invention has a simple configuration that solves the problemsExisting other sofa beds.
    According to the invention, the sofa bed comprises:-a support structure on the ground,- a main seat base arranged in said structure,-An unbeatable front legrest, which is fixed to the structure througha first joint, and-a flexible fluffy body that is covering the main base and the legrest.
    The previous configuration can be complemented with a backup, although simplyyou can have some pillows resting on the wall, if the sofa bed of the invention isavailable in this placement.
    Thus, unhooking the legrest and placing it coplanarly with the base ofseat, the widths of both add up resulting in a wide bedconsiderable without the need for excessive seating or occupancygreater than the furniture, not requiring the separation of the furniture from the wall, and also, notrequiring storage of cushions or sofa cushions in the configuration


    of bed, since the soft body of the armchair configuration constitutes the mattress of the bed configuration, for which it must be flexible, or have a flexible area in coincidence with the first joint. In addition, this configuration has the unexpected advantage that placing the legrest at intermediate heights serves precisely
    5 for leg support. DESCRIPTION OF THE DRAWINGS

    PREFERRED EMBODIMENT OF THE INVENTION
    The sofa bed (1) of the invention comprises:-a support structure (2) on the ground,- a main seat base (3) arranged in said structure (2), in its upper part,-An unbeatable front legrest (4), which is fixed to the structure (2) throughof a first joint (5) (see fig 2), and-a flexible fluffy body (6) that is covering the main base (3) and thelegrest (4).
    In the preferred configuration, the first joint (5) comprises mechanisms (7)parallel (see figs 2 and 4) of movement in vertical plane (that is, with shaft jointshorizontal) with combined movement of disengagement and advancement of the legrest (4),so that the fluffy body (6) does not protrude from the legrest (4) in configuration ofbed; very preferably the mechanisms (7) comprise (see fig 4):-a first connecting rod (70) and a second connecting rod (71) joined respectively by asecond articulation (72) delayed and a third articulation (73) advanced to a sectionhorizontal (30) transverse base (3),-a third connecting rod (74) joined by a third joint (75) to the first connecting rod (70) andby means of a fourth joint (76) superior to the legrest (4),-a fourth connecting rod (80) joined by a fifth joint (77) to the second connecting rod (71) andby a sixth joint (78) lower than the legrest (4),-a seventh joint (79) that is relating the initial part of the thirdconnecting rod (74) with the final part of the second connecting rod (71), and-where the second connecting rod (71) and the fourth connecting rod (80) are straight and the first connecting rod (70) and theThird rod (74) have initial sections (70th, 76th) angled. This configuration simplifiesthe number of cranks and is robust. The mechanisms (7) can be arranged in anyposition, although in the present embodiment they have been arranged on both base sides (3) andlegrests (4), since in this way it is not necessary to make additional cuts in thelegrest or structure (3).
    Precisely to support the weight that is available on the legrest (4) inbed configuration, the invention has provided the arrangement of lower legs (8)


    under it. Said lower legs (8) are preferably joined to the lower part of the legrest (4) through an eighth joint (9) (see figs. 1, 2 and 5) that allows partial rotation of the legs (8) with respect to the leg rest (4) during furniture transformation movements. It is also provided that the lower legs (8) comprise some extreme wheels (10) to facilitate said movements, when rolling on the ground.
    A very preferred configuration of the sofa bed (1) of the invention has provided that the legrest (4) comprises automated disengagement means, which allow mobility towards both extreme bed and sofa positions, and even intermediate positions where the legrest (4) ) precisely configure a leg support for users in armchair configuration. Said means may comprise motors, hydraulic cylinders or any other known, using in the most preferred configuration of the invention, due to its simplicity, at least (see figs. 2 and 5), a first linear actuator (11) which is mounted on the structure (2) and directed towards the legrest (4), and is connected to pushers (12) through a ninth joint (14); and the pushers (12) being connected to said legrest (4) through a tenth joint (15). This tenth joint (15) is ideally arranged in a crossbar (8a) that is joining the lower legs (8), so that the furniture transformation movements simultaneously produce the extension and retraction movements of the legs (8) . Said pushers (12) preferably have an angular shape since in the tests carried out it has been found that they work offering less resistance, having provided higher supports (12a) (see fig. 5) for the leg rest (4) that save the gap generated precisely by the angular shape and give an additional support point that maintains the horizontality of the legrest (4) in bed configuration.
    The invention has provided the additional arrangement of a backrest (16) for the sofa bed (1) (see figs. 1, 6 and 7). Said backrest (16) ideally comprises a rear cross member (17) fixed between two arms (18) which are in turn fixed to the structure (2), providing support cushions (19) on said cross member (17). This achieves a configuration that takes up very little space and does not bother the use in bed configuration. However, it is provided that the arms (18) can be fixed to the structure
    (2) through eleventh joints (20), comprising means of regulating the


    elevation of said arms (18). This allows from the height adjustment of the support of the backrest (16) to the complete retraction of the same, leaving the bed completely clear. For this, said arms (18) must be slightly longer than the distance of the eleventh joints (20) to the end or edge of the main base (3).
    The means for regulating the elevation of the arms (18) can be of any type existing in the state of the art, being able, for example, to include non-return ratchets, not shown, and / or at least a second linear actuator ( 22) (see fig 7) articulated by means of bars (23) to fifth connecting rods (24) attached to the arms (18)
    10 (see fig 6).
    Finally, indicate that the flexible fluffy body (6) has machining (25) or cross-holes in the area coinciding with the first joint (5) to favor flexibility in this area that favors bending without hollowing or lifting the fluffy body
    15 (6) in the area of the seat base (3).
    Sufficiently described the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to detailed modifications in
    20 as long as they do not alter the fundamental principle.
