[Embodiment of the invention]

 An embodiment of the present invention will now be described with reference to the drawings. In a couch sofa provided with a back portion (1) having an L-shaped continuous back portion (1a) and side portion (1b), the back portion is provided. A base (2) is integrally provided below the part (1), and the base (2) has a guide groove (Y) extending diagonally from an even angle part (X) of the backrest part (1). ), And a guide portion (5) provided at the bottom of the sofa body (4) having the casters (3) with stoppers is inserted into the guide groove (Y), and the sofa body (4) is fitted along the guide groove. ) Is a couch sofa that is guided and moved.

As one embodiment of the guide part (5), as shown in FIG. 3, a base (2) provided integrally with the backrest part (1) has two guide grooves (Y). They are provided in parallel. On the other hand, a guide portion (5) provided at the bottom of the sofa body (1) has an arm (5a) extending downward, and the lower end of the arm (5a) has the guide groove (Y) (Y). Rolling rollers (5b) and (5b) to be fitted respectively are provided, and these rolling rollers are guided by guide grooves (Y), and both ends of the guide grooves are formed by the diameters of these rolling rollers. A stopper recess (Ya) having a large diameter is formed, and is fixed by abutment of the arms (5a) and (5a) of the guide portion (5) with the base (2).

[0008] Further, the casters with stoppers (3) of the sofa body (1) are provided at three places of each even-angle part, and are not provided at the even-angle part (A) of the backrest part (2). It is.

When using the present invention, first, the stopper of each caster (3) is released, and the sofa body (1) is moved along the guide groove (Y), that is, in the oblique direction. If it is slid, the part of the sofa spreads as shown in Fig. 2 and can be used like a bed, and conversely, it transforms into the original couch sofa as shown in Fig. 1.
