Therefore, when the backrest 2 is changed from the backrest mounting portion 4 to the backrest side mounting portion 5, the backrest surface portion of the backrest portion 2. 8 by adjusting the folding amount of the left and right ends, and adjusting the length (width dimension) suitable for the mounting state of the backrest side mounting portion 5 (that is, adjusting the interval between the backrest column portions 13 to an appropriate interval) The bed base 6 is formed by attaching the backrest 2 having this length adjustment to the backrest side attachment 5.

  Then, the four cushion members 3 removed on the bed base 6 are laid in a continuous state in a direction in which the long sides of the cushion members 3 abut against each other, thereby converting the form into a bed form. finish.

  That is, in the present embodiment, the dimension of the short side of the backrest surface portion 8 of the backrest portion 2 is set to ½ of the short side dimension of the base portion 10 (cushion member 3), and the backrest portion 2 is When attached to the sofa pedestal 1, the back side 8 is attached in a state where the long side of the back side 8 abuts against (or abuts on) the pedestal of the sofa pedestal 1. The backrest 2 is attached to the left and right sides of the sofa base 1 so that the length of the short side dimension of the base 10 (the short side dimension of the cushion member 3) is exactly the same. The bed base 6 has a length corresponding to four base parts 10. Therefore, four cushion members 3 having substantially the same shape and dimensions as the base part 10 are provided on the bed base 6. The cushion member 3 may jump out of the sofa base 1 or the length may be insufficient. ® down member 3 without are formed partial absence, it is possible to form a bed form is tightly cushion member 3 on the entire surface of the bed base 6 laid.

  Further, in the bed form of the present embodiment, since the dimensions of the base portion 10 are 75 cm long and 50 cm short, the dimensions of the bed base 6 are 75 cm wide and 200 cm long, which is sufficiently wide as a bed. It is possible to form a practical bed configuration that secures the height.

  Further, in this bed configuration, either the left or right backrest 2 is removed from the backrest side mounting portion 5 and the length of the backrest surface portion 8 is adjusted to attach the backrest strut portion 13 to the third backrest mounting portion. By inserting and engaging with 23, it is possible to change from a flat bed configuration to a bed configuration in a back-up posture with one side rising.

  Moreover, when converting a form from a sofa form to a table set form, after removing the backrest part 2 from the backrest attachment part 4, first, the three bases in the connected state forming the sofa base part 1 Part 10 is disconnected and put into a separated state.

  Next, of the three separated base parts 10, two base parts 10 are formed into a chair shape. Specifically, the backrest part 2 removed from the backrest attachment part 4 is attached to the second backrest attachment part 15 of the base part 10, and this backrest part 2 is substantially central in the long side direction of the base part 10. A chair base 25 is formed by projecting upward in a slightly rearward tilted state, and the cushion member 3 is placed on the chair base 25 in the same direction as the base portion 10 forming the chair base 25. In addition to laying, a cushion member 3 is disposed on the backrest 2 to form a chair for one person. In this embodiment, when the cushion member 3 is disposed on the backrest portion 2, the cushion member 3 is folded in the long side direction, and the folded cushion member 3 is covered from above the backrest portion 2. By providing in this way, the appearance is more similar to a general chair.

  Thus, the assembly type sofa of this embodiment can be used as a table set by using the two base portions 10 as a chair and using the remaining integrated base portion 10 as a table. In this embodiment, the base unit 10 is used as a table as it is. However, for example, a table may be formed by providing a top plate on the base unit 10.

  As described above, this embodiment can convert the form into three forms of a sofa form, a bed form, and a table set form. In addition, in the sofa form, both the width (length) and the depth of the left and right sides of the seat portion can be obtained. It is shorter (narrower) than the bed form and can be just the right size (shape) as a sofa. When the form is converted to the bed form, the length and width are both larger than the sofa form. It becomes a bed form having a bed surface of a large size, and becomes an assembling-type sofa that is extremely convenient and practical.

  In addition, this embodiment can be easily realized by an extremely simple operation of changing the mounting position of the backrest portion 2 and re-laying or reattaching the cushion member 3 at the time of form conversion. Since both the part 2 and the connecting member 19 are inserted and engaged, no need for tools such as a screwdriver for assembly work, and anyone can easily assemble and perform form conversion work. It becomes a typical assembly type sofa.
