DESCRIPTION

SOFA BED

TECHNICAL FIELD OF THE INVENTION

The present invention is included in the field of sofas that can be converted into beds by tilting or rotating their backrest. Specifically, it is related to a sofa bed that includes a more resistant, reliable support base, as well as one that maintains its aesthetic appearance despite its use.

BACKGROUND OF THE INVENTION

Various designs of folding sofas, "book" type, which can be converted into a bed, are known.

Normally, these types of sofas consist of two wings or sections, which respectively make up the seat and back of the sofa. These seat and back sections are articulated with each other by means of kinematic mechanisms that are in turn fixed to smaller walls of a support base of the sofa, so that when the seat and back sections are opened, that is, lowering Said backrest section forms a horizontally extended surface that can be used as a bed, taking advantage of the soft surfaces of the seat and backrest sections of the sofa as a mattress.

Due to the weight they support, both when the sofa-bed is used as a seat with a backrest and when it is used as a bed, the larger walls of the support base end up deforming, that is, arching or opening outwards from the sofa-bed, giving a bad aesthetic appearance to said support base of the sofa and, furthermore, giving the impression of not being a reliable support surface for rest.

Therefore, it is necessary to design, in a simple and economical way, a sofa-bed that manages to solve the previous disadvantage.

DESCRIPTION OF THE INVENTION

The present invention is established and characterized in the independent claim, while the dependent claims describe other features thereof.

The object of the invention is a sofa-bed. The technical problem to be solved is how to achieve a more resistant support base for the sofa-bed, with a better aesthetic appearance, and that gives the impression of being reliable to the user.

The sofa bed includes:

- a support base, configured as a box with larger walls, smaller walls and a bottom,

- a back section and a seat section, and

- respective kinematic mechanisms, fixed to the smaller walls of the support base and configured to articulate the back section and the seat section, so that the back section is able to form a horizontal extension of the seat section when the back section is swung down and rests on the support base to form a bed.

Where, the support base comprises at least one interior crosspiece fixed between its larger walls. The support base could comprise one or two interior crosspieces, for example, made up of individual wooden bars, which provide greater resistance to bending to the corresponding larger walls of the support base that they join, giving said support base greater solidity. without taking away storage functionality.

In this way, it is possible to form a sofa-bed with a more resistant support base, with a better aesthetic appearance, and which gives the impression of being reliable in the eyes of the user.

BRIEF DESCRIPTION OF THE FIGURES

This descriptive memory is complemented with a set of illustrative figures of the preferred example, and never limiting the invention.

Figure 1 represents a front perspective view of the sofa-bed with the backrest section in the raised position, to form a seat with a backrest.

Figure 2 represents a side perspective view of the sofa-bed of figure 1 with the back section balanced downwards, to form a bed.

Figure 3 represents a side perspective view of the support base of the sofa-bed of Figure 1, showing an embodiment that includes an internal crosspiece.

DETAILED DISCLOSURE OF THE INVENTION

The present invention is a sofa-bed, which, as shown in figures 1 and 2, comprises:

- a support base (1),

- a back section (2) and a seat section (3), and

- Some kinematic mechanisms (4).

As shown in figure 3, the support base (1) is configured as a box with larger walls (1.1), smaller walls (1.2) and a bottom (1.3). Thus, the support base (1) can form a storage space (5) for objects below the backrest and seat sections (2, 3) of the sofa-bed.

Additionally, the support base (1) comprises at least one inner crosspiece (1.4) fixed between its larger walls (1.1). For example, the interior crossbar(s) (1.4) could be fixed, through their ends (1.41), between two upper parts or halves (1.11) of the larger walls ( 1.1). For example, by means of screws (not shown in the figures). In any case, it is sought that the larger walls (1.1) of the support base (1), compared to the weight they support both when the sofa-bed is used as a seat with a backrest and when it is used as a bed, are more resistant and do not end up deforming. , that is, arching or opening outward from the sofa bed; and with this, the aesthetic appearance of the support base (1) of the sofa-bed is kept intact, as well as giving the impression of being a reliable support surface for resting.

To do this, as shown in the preferred embodiment of figure 3, an inner crosspiece (1.4) can be used located substantially in the center of the larger walls (1.1), or two or more inner crosspieces (1.4) distributed equidistantly along the larger walls (1.1) (embodiments not shown in the figures). The use of one or two interior crosspieces (1.4) could be sufficient to keep the larger walls (1.1) of the support base (1) rigid and supported by each other; however, obviously, the more internal crossbars (1.4) are fixed between the larger walls (1.1) of the support base (1), the greater rigidity and resistance to bending will be provided to said larger walls (1.1) of the support base ( 1). For this reason, the number of interior crosspieces (1.4) to be used could be conditioned by the length of the longest sides (1.1) of the support base (1) of the sofa-bed, so that as many interior crosspieces (1.4) are included as They are necessary to keep the larger walls (1.1) rigid and supported by each other, compared to the weight to be supported by the support base (1).

Preferably, the inner crossbar (1.4) could be a wooden bar, or of any other material that is suitable for keeping the larger walls (1.1) rigid or supporting each other.

As for the kinematic mechanisms (4), these are fixed to the smaller walls (1.2) of the support base (1), and are configured to articulate the back section (2) and the seat section (3). , so that, starting from the configuration of the seat with the backrest of the sofa-bed shown in figure 1, the backrest section (2) is capable of forming a horizontal extension of the seat section (3) when the backrest section (2) is balanced downwards and rests on the support base (1), and in this way, forms the bed configuration shown in figure 2.

Preferably, the back section (2) and the seat section (3) are fixed to the kinematic mechanisms (4) by means of screws (not shown in the figures).

In the same way, it is preferred that two pieces or foam cushions (not shown in the figures) be placed on the back and seat sections (2, 3), of appropriate thickness and density, giving a more comfortable support to the user. sofa bed both when used as a seat with a backrest and when used as a bed.
