Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sofa / bed which can be displaced between a bed mode and a sofa mode.

[0002]

2. Description of the Related Art Various sofa beds have been commercially available. As a typical sofa and bed,
For example, a single-sized bed is divided into two halves in the longitudinal direction, and when using the sofa-bed as a sofa (sofa mode), raise the back half of the bed toward you. There is something like using it as a backrest.

However, as is well known, since the bed portion is divided in the sofa / combined bed of the above-mentioned type, when the single bed is used, a step is generated in the divided portion, which just hits the vicinity of the back of the user and makes the user feel comfortable. Very bad. Furthermore, the softness (or hardness) generally required for beds
And, unlike the softness required for the backrest, in the conventional sofa combined bed of the above type, the same components have to be used for both the bed and the backrest,
It is difficult to select the softness.

In order to solve such a problem, for example, in Japanese Utility Model Laid-Open No. 54-164010, Japanese Utility Model Laid-Open No. 60-187654, and Japanese Patent Laid-Open No. 109509/1990, a sofa / bed having a dedicated backrest is proposed. In these sofa beds, when the backrest is not used, the backrest is moved from the bed surface to another place.

[0005]

However, such a conventional sofa / bed has a problem that the backrest becomes an obstacle when the backrest is not used. That is, for example, the actual exploitation Sho 60-187654
In the sofa / combined bed described in 1 above, when not in use, the backrest lays on the floor in front of the sofa / combined bed, which impedes access to the bed.

[0006] Therefore, the applicant has filed Japanese Patent Application No. 4-33418.
No. 6, Japanese Patent Application No. 4-334187 and Japanese Patent Application No. 4-334.
With No. 188, we proposed a completely new type of sofa / bed that can be converted into bed mode and sofa mode. These have an excellent effect that they are comfortable to sleep and that the backrest can be arranged at a position where the backrest does not interfere when the backrest is not used.

However, the size of the new type of sofa / bed is the same as that of the above-mentioned conventional example, because it is a specification of a single bed, so that the floor area is wide to accommodate a large-sized person or two persons. There has been a long-felt need for application to a double bed that can be placed on the backrest so that the backrest can be placed in a position where it can be picked up and is not in the way when the backrest is not used.

The present invention has been made by paying attention to the problems of the prior art as described above. The backrest is placed in a position where it is comfortable to sleep in the bed mode and does not disturb the backrest when it is not used. The purpose of the present invention is to provide a double bed type sofa / combination bed that can secure a larger floor area.
