Abstract

PROBLEM TO BE SOLVED: To newly provide a chair, a sofa and a sofa bed wherein angle of inclination of the back is opened without tilting the back backward or which can be used as a bed. SOLUTION: Projections 5a and 5b are provided on both sides of the backs 2a and 2b curved from the depth end of seat parts 1a and 1b and continuously raised and inclined channels 6a and 6b into which the projections 5a and 5b are fitted and moved and provided with an inclination whose bottom ends are forward projected are provided on side face members 3a and 3b of both outsides and the projections 5a and 5b are fitted therein. Then, by moving downward the backs 2a and 2b accompanied with the projections 5a and 5b, the angle of inclination of the back are opened and are made adjustable and it is changed into a bed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a chair or sofa and a sofa bed.

[0002]

2. Description of the Related Art There are chairs and sofas with thick backing made of cushioning material, in which the backrest can be tilted rearward to widen and adjust the backrest inclination angle.

[0003] The same applies to the case where a sofa bed is switched to a sofa or a bed. In some cases, a backrest is raised to make a sofa, and the sofa is tilted backward to switch to a bed.

[0093]

However, in view of the fact that these thick cushion-made chairs, sofas and sofa beds are large-sized furniture and that the room can be effectively used, the backrest is applied to a wall surface or the like. In many cases, it is necessary to move the chair or sofa to the front when the backrest is tilted rearward to widen the backrest angle or switch to the bed. When installing the backrest away from the wall, there is a problem of taking up a lot of space.

[0005]

SUMMARY OF THE INVENTION The present invention solves such a problem by enabling the backrest to be inclined at a wider angle or to be converted from a sofa to a bed simply by moving the backrest down along the inclined groove. I did it.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 relate to a two-seat sofa, and are connected to stool portions 1a and 1b made of thick cushioning material with a tendency to expand from the back ends thereof. Side members 3a and 3b made of a cushion material having a similar thickness are applied to both outer sides of the backrests 2a and 2b. 3c is an intermediate member, 4 is a bottom plate.

As shown in FIG. 2, protrusions 5a and 5b are provided on the surfaces of the backrests 2a and 2b at the intermediate portions on both sides, and the protrusions are provided on the inner surfaces of the side members 3a and 3b and the upper surfaces of both surfaces of the intermediate member 3c. It is movably fitted to and supported by each of the short inclined grooves 6a and 6b provided at the same position and having the above-mentioned inclined lower end.

When the backrests 2a, 2b are moved down by the protruding portions of the seats 1a, 1b as shown in FIGS. 1 (b), 1 (c) and 3, the protruding members 5a, 5b are inclined downwardly. Move down along the short inclined grooves 6a, 6b attached to the backrest 2a,
The backrest inclination angle of 2b is gradually increased.

FIG. 4 is the same as the above-described embodiment except that a single-seat chair 7 is provided.

FIGS. 5 to 9 show the sofa bed in the state of the sofa 8 and the state of the bed 9. Side member 1
The backrest 1 is inserted into long inclined grooves 11a, 11b which are formed so as to be inclined from the upper part to the lower part of the inner surfaces of the inner surfaces 0a, 10b.
When the backrest 12 is moved downward by pulling forward a stool 14 formed so as to be foldable and deployable, the backrest 12 is formed by a long inclined groove 11a. , 11b to sleep gradually and finally present a horizontal position, and the unfolding stools 14a, 14b,
The bed 9 is formed with the bed 14c and the stool 14 and the backrest 12 are returned to their original positions to form the sofa 8.

Reference numeral 15a denotes a stopper provided on the thin bottom plate 15, reference numeral 16a denotes a front roller provided on the bottom surface of the seating portion 14a, and reference numeral 16b denotes a rear roller, as shown in FIG. Stopper 1 with front roller 16a
The point that the inclination angle of the backrest 12 can be widened by getting over the vehicle 5a and applying the rear roller 16b to the stopper 15a is the same as the chair and the sofa of the previous example.
Further, by increasing the number of rollers to three or more at intervals, and appropriately selecting a roller to be applied to the stopper 15a, the spreading inclination angle of the backrest 12 can be adjusted to an arbitrary angle of two or more.

FIG. 10 shows the inclined grooves 6a, 6b or 11a,
This is an example in which a crank-shaped stopper portion 17 is provided on 11b. By providing one or several stopper portions 17, the spread inclination angle of the backrest can be adjusted to two or more arbitrary angles. . In addition, the protrusions 5a,
5b, 13a, and 13b may be fitted with a bearing roller 18 for smooth movement.

[0013]

As described above, according to the present invention, when the backrest is moved down, the backrest can be extended along the inclined groove and the reclining angle can be increased, and in a sofa bed, the backrest can be lowered. It is possible to convert from a sofa to a bed simply by moving the camera, and the conversion operation becomes extremely simple. Even if there is no gap between the backrest and the wall, the backrest tilt angle of the backrest can be widened or the bed can be folded down, making it possible to attach a chair, sofa, sofa bed to the wall, etc. The effect that it can be installed in a car is produced.
