Definitions

• the present invention relates to a seat of the sofa bed or other transformable type.
• a sofa convertible into a bed and vice versa These generally comprise a support structure generally produced in profiles, this structure comprising a fixed part and a movable part which support elements of padding of the backrest and the seat.
• the padding elements are generally constituted by an expanded material of the foam type, closed in a fabric, leather or other cover.
• Transformable sofa beds of this type are expensive, either because of the manufacture of the frame or structure, or because of that only of the upholstery elements.
• these convertible sofa beds include a frame constituting the fixed sofa with its own padding and a frame articulated in several parts which folds back into the fixed part of the seat. This articulated frame constitutes the bed proper with its spring or suspension elements and of its own stuffing.
• Such couches do not allow an intermediate position of relax or an orientation at will of one of their part, for example the part constituting the back.
• Such seats have a frame with a three-part periphery frame connected to one another by means of adjustable hinges.
• a braiding generally in canvas, to support the user.
• Such a device can be provided with a mattress or receive one.
• the three parts generally have the same dimension, which allows them to be overlapped to reduce bulk and facilitate transport.
• Such seats cannot be assimilated to transformable couches.
• the purpose of the present invention is to provide a sofa convertible into a bed, which is simple to produce both in terms of the frame and upholstery elements, this couch being capable of allowing oriented operation of at least one and possibly of several of its parts, this couch also having the advantage of being composed of a reduced number of elements and to be very comfortable.
• the sofa convertible into a bed according to the invention comprising a support frame, padding and a blanket, is characterized in that:
• the support frame comprises a peripheral chassis in several successive sectors, connected by hinges, at least one hinge and preferably the hinge interposed between the backrest and the adjacent sector being of adjustable orientation,
• the padding is a continuous element in which the support frame is integrated
• the external cover is a cover which envelops the padding elements in which the support frame is housed, - preferably between the longitudinal uprights of the peripheral frame are arranged transverse elements with internal support function of the padding elements.
• the part of the padding consists of two elements made of expanded material arranged one on the other and elongated over the entire frame; for this reason the incorporated cover is used for fixing the two elements by taking the frame between them.
• said transverse elements having a support function are preferably flexible or flexible elements, for example straps, fixed by means of end hooks to the peripheral chassis.
• the peripheral reinforcement comprises a part forming the back, a part forming the bottom or base, a straight part and a part forming a seat, the part of the bottom having, in an interresting manner, feet fixed for support.
• the hinges with adjustable orientation can be provided at all the connection points of the various parts of the chassis, so as to allow positions to be obtained as desired. to relax.
• the convertible upholstered couch according to the invention has the advantage of an extremely simple construction, for example in four frame sectors made of peripheral tubes fixed simply by means of hinges, which act as a link.
• the advantage of such a frame is that it does not require any particular finishing work, since it is incorporated into the filled part and in this way becomes invisible.
• Another advantage consists in the free choice of the cross section of the tubes used for the formation of the frame, the free choice of the conformation to be given to the different sectors of the frame and, thereby, to the final conformation of the couch.
• FIG. 1 is a perspective view of the support frame of a couch according to the invention, the solid line and the dotted line indicating two positions of inclination of the backrest, - Figure 2 is a view of the frame in bed position, the solid line and the dotted line indicating, once again, two orientation positions of the backrest and seat part,
• FIGS. 3 and 4 illustrate in particular, in perspective, an easily oscillating hinge and a hinge with adjustable orientation, usable in the frame according to the invention
• FIG. 5 shows part of the padding in the form of two profile half-pads
• FIG. 6 shows a perspective view of a padded convertible divan according to the invention
• FIG. 7 shows a vertical section of Figure 6, -
• FIG. 8 illustrates another embodiment in which all the hinges are of the type with adjustable orientation to allow various positions to be obtained
• the seat of the sofa type 1 convertible into a bed according to the invention is composed of a peripheral support frame (2) (that follows the outline of the sofa), of a part padding (3) and a part serving as a cover (4).
• the frame 2 is provided with a frame formed by four successive sectors: more specifically with a back part 5, of a part forming the bottom 6 or base, of a vertical part
• Such parts are advantageously produced in a hollow or tubular profile, which, to reinforce them, can be connected by crosspieces 9.
• the parts 5 - 8 are connected to each other by the hinges 10,
• the hinges 10, at least, that is to say those interposed between the part of the back 5 and the part constituting the bottom 6, are adjustable in orientation to allow orientation, as desired, of the back part 5.
• hinges 11 and 12 are hinges with free rotation up to 90 °.
• the vertical parts 7 and that forming the seat 8 can be rotatable at an angle of 90 ° and allow their positioning in the same horizontal plane as the part forming the bottom 6.
• the latter has fixed support legs referenced by 13.
• the padded part 3 can be made of two half-padding 14, 15, composed of two elements in one or more pieces of foam-type expanded material, as a mattress.
• cover part 4 provided in the form of a hous ⁇ .
• cover cover 4 includes a zipper, not shown, allowing it to be closed and opened.
• the cover for covering and assembling and holding 4 is made of an elastic material, in order to follow the profile of the external face of the half-paddings 14 and 15.
• Said half-padding 14 and 15 may, in fact, have profiled sectors, or alternatively cross sections to obtain the shape or the appearance as desired of the convertible sofa bed produced according to the invention.
• the drawings represent an external embodiment.
• the padded part 3 can also be obtained by laying foam directly on the frame 2.
• the reference 17 indicates the transverse elements having the function of supporting the padding part 3 (or else 14 , 15). These transverse elements 17 are provided in the form of straps provided with hooks 18 at the ends, engaging for example in the slots 19 formed on the sectors 5-8 of the frame.
• hinges 10 with adjustable orientation the dos ⁇ sier part 5 can be arranged at the drawn angle as shown in the drawing by a continuous line and a dotted line. Similar hinges with adjustable orientation can also be used for the hinges 12 or else for the hinges 11 and 12, it will then be possible to position in inclination, also as shown in FIG.
• FIG. 9 represents a simplified embodiment of the invention providing a low seat of the cushion or bench type, that is to say comprising only sectors 6-7 and 8 excluding the backrest 5.
• This description clearly illustrates that the structure of the convertible couch according to the invention achieves a basic concept of the invention and achieves the advantages mentioned above.
• an extremely simple execution support frame is obtained which does not require finishing phases, as is usual for frames, as also the padding part is obtained in a simple manner, while pou ⁇ vant present areas of density or various thicknesses depending on their support function, for the seat part, or support as for the back part.
• Another advantage of the frame integrated in the padding, that is to say disposed between two layers of padding, is that:
• the lower layer acts as a box spring and the upper layer of mattress, they can for this purpose be of different densities,
• the weight of the person is not supported by and transmitted directly to the frame as is generally the case but on the contrary it cooperates with the lower layer when it receives the weight of the user.
• the peripheral uprights of the chassis although rectilinear, could have a curvilinear shape, both on the horizontal plane and on the vertical plane and, more particularly aus ⁇ so well in a concave than convex direction, so as to leave the maximum freedom of design in connection with the possibility of profiling the padding for the arrangement of the final appearance or the shape of the sofa.
• the above is valid for armchairs convertible into beds or poufs or benches.
• the frame can be made of metal as well as plastic.
