  However, the above-mentioned sofa bed has a drawback that such a sofa bed has a complicated structure, switching between the sofa and the bed is troublesome, and can only be performed for a specific user. I have.

  An object of the present invention is to provide a multifunctional sofa bed which has a simple structure and is easy to use.

  The present invention has been made to achieve the above object, and a mat, a support frame and legs of a sofa are sequentially connected, and the backrest is fixed to the support frame with at least two or more articulators under the backrest. The backrest is a multifunctional sofa bed consisting of a coil spring and a sponge.

  Another aspect of the present invention is a multifunctional sofa bed having an L-shaped backrest and a rectangular shape in combination with a mat.

  In another aspect of the present invention, the lower surface of the backrest is a multifunctional sofa bed fixed to a support frame by four four-stage switching connecting devices.

  Further, another invention provides a substantially L-shaped mat and a substantially L-shaped backrest in a shape constituting one square bed, provided on the lower surface of the mat, and a support frame for supporting the mat. A leg connected below the support frame and in contact with the floor, and a connecting device for connecting between the backrest and the supporting frame, the connecting device for changing the height of the backrest, further comprising a connecting device. With the backrest at the same height as the mat when it is down, the main body is a square bed, and when it is upright, the backrest is placed above the mat, and the main body is a sofa, and the main body is a sofa I have.

  Another aspect of the present invention is a multifunctional sofa bed including one or more joints in the articulating device, the joints being fixed in multiple stages, and the height of the backrest being changed in multiple stages.

  The present invention has a feature that the structure is simpler than the existing sofa bed, the two kinds of functions can be easily converted, and the effect is that it is easy to use for any user.

  The purpose of the present invention is to realize the following.

  The sofa bed of the present invention is composed of a mat and an iron frame, the feature of which is that the mat, the support frame and the legs of the sofa are connected, and the lower surface of the backrest is fixed to the support frame by at least two or more connecting devices. ing. Therefore, the backrest can be translated right and left about the axis of the connecting device. The backrest is composed of a coil spring and a sponge. When the present invention is used as a sofa, the backrest is moved to the highest position, and when the present invention is used as a bed, the backrest is moved to the lowest position, and the backrest and the mat constitute one plane.

  The present invention will be described with reference to the drawings.

  The mat 4, the support frame 7 and the leg 5 of the sofa are sequentially connected, the backrest 1 is L-shaped, and the L-shaped backrest 1 can be made rectangular with the mat 4. The lower surface of the L-shaped backrest 1 is fixed on a support frame 7 by four four-stage switching connectors 6. This allows the backrest 1 to be parallel to the left and right about the axis of the connecting device 6. Since the four-stage switch 6 is used, four kinds of height adjustments are possible, and the present invention can meet various demands. The backrest 1 includes a coil spring 3 and a sponge 2. When the present invention is used as a sofa, the backrest 1 is moved to the highest position, and when the present invention is used as a bed, the backrest 1 is moved to the lowest position, and the backrest 1 and the mat 4 constitute one plane. .

  The connecting device 6 is not limited to a device that can be switched in four stages, but may be a device that can be switched in two stages, three stages, or five or more stages. Further, the connecting device 6 may be a device that can be switched steplessly. Further, the mat 4 and the backrest 1 may have shapes other than the substantially L-shape as long as they can form a quadrangle with each other. For example, the mat 4 and the backrest 1 may each be two triangles separated by a square diagonal.

In particular, by making the backrest 1 substantially L-shaped, it is possible to form a sofa in which a plurality of persons sit in a substantially 90-degree direction. In addition, by adopting the articulator 6 that allows the backrest 1 to be variable in four stages, a bed in which the backrest 1 is arranged at the lowest position and an adult for which the backrest 1 is arranged in the highest position are provided. The sofa and the sofa for the child or the elderly with the backrest 1 at the second highest position and the third highest position can be freely formed. Further, by making the connecting device 6 have a structure of five or more steps or a stepless variable structure, it is possible to form a sofa suitable for a wide variety of people.

It is the figure which looked at the state which made this invention a sofa from the front. FIG. 3 is a view showing a state in which the present invention is in a bed. It is the figure which looked at the state which made this invention a sofa from the back.
