DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress for use as a bedding / sofa, which has a plurality of mattress components, and in which predetermined adjacent mattress components among the mattress components are recliningly connected.

[0002]

2. Description of the Related Art In recent years, beds have been widely used as bedding with the westernization of lifestyle.

FIG. 10 shows a general configuration of a bed.

In the figure, reference numeral 50 denotes a bed body, 53 denotes a mattress, and 54 denotes a headboard.

The bed body 50 includes a frame 51, legs 52, and the like, and is configured to have a structural strength sufficient to support a mattress 53 and a human body lying on the mattress 53. The mattress 53 incorporates an elastic body (for example, a large number of springs (not shown)) and is formed to be capable of elastically supporting a person. The headboard 54
It is provided on the head side of the mattress 53.

Although the above-mentioned standard type bed is widely used, recently, a mattress 1A which can be used both as a bedding at night and as a sofa during the day has been put to practical use so that a small living space can be effectively used. ing.

[0007] Such a bedding / sofa mattress 1A
As shown in FIGS. 11A and 11B, the mattress body 2 can be folded at a plurality of locations (a, b) in the longitudinal direction, and when used as a sofa, it is shown in FIG. 11B. To form a seat 2S and a backrest 2B.

[0008]

The bedding / sofa bed 1A described above merely folds the mattress body 2 into a sofa shape, so if the backrest portion 2B leans too much on the backrest portion 2B, the backrest portion 2B will fall. It is dangerous to fall behind without being able to support the human body.

Therefore, the bed 1A for both the bedding and the sofa is used.
When used as a sofa, it is often installed such that the backrest 2B contacts the wall 5, as shown in FIG. However, in this case, the installation position is limited, which is a problem from the viewpoint of effectively utilizing the living space.

Further, the angle (inclination angle) of the backrest 2B with respect to the seat 2S is fixed, and there is a problem from the viewpoint of usability. For example, there is little problem in leaning on the backrest 2B when serving customers, but there is no problem. However, when watching TV, it is more comfortable if the backrest 2B falls down greatly.

As shown in FIG. 12, there is a nursing bed in which a floor plate 51A of a frame 51 can be reclined, but the frame 51 provided with a reclining mechanism (not shown) can be bent. However, it is difficult to reduce the size of the bed, and it is extremely difficult to develop a bed for both bedding and sofa based on the bed for nursing care.

An object of the present invention is to provide a mattress that is used as a sofa and can be easily reclined by being installed at an arbitrary place, and that can be used as a sofa.

[0013]

SUMMARY OF THE INVENTION The present invention is directed to a plurality of mattress components connected to each other so as to be capable of elastically supporting a human body and to be relatively rotatable, and a plurality of mattress components between predetermined adjacent mattress components. And a reclining mechanism that can adjust a connection angle between the two.

According to the invention, the inclination angle of the mattress component supporting the upper body of the human body can be adjusted by using the reclining mechanism. Therefore, even when the mattress component is used as a sofa, it is not necessary to limit the installation place. In addition, since the reclining mechanism is provided between the adjacent mattress components, the structure is complicated unlike the conventional nursing bed where the reclining mechanism is provided on the frame of the bed body.
Does not increase in size. Therefore, it can be installed at an arbitrary place, used as a sofa, and easily reclined.
