The caster 216 may be a fixed wheel with a fixed wheel direction, or a flexible wheel with a variable wheel direction. The caster 216 has a stopper mechanism 217 (FIG. 3) that prevents movement by the caster 216 by inhibiting the rotation of the wheels.

A usage example of the convertible sofa 1 according to the present embodiment will be described below with reference to FIGS. 2 to 6. FIG.

2 shows an example of use in the basic mode, FIGS. 4 and 5 show an example of use in the first reclining mode, and FIG. 6 shows an example of use in the second reclining mode. The second backrest 213 is in the same reclined position in the first reclining mode and the second reclining mode. FIG. 3 shows the work performed by the user when changing the layout of the convertible sofa 1 from the basic mode.

In the basic mode, the second backrest 213 of the seat sofa section 21 is set to the standing position, and the couch sofa section 11 and the seat sofa section 21 are positioned between the side edges 113s of the first backrest 113 and the second backrest 213. They are arranged side by side with the side edges 213s in contact with each other. In the arrangement of the basic mode, the first seat cushion 112 and the second seat cushion 212 form an L-shaped seat surface when viewed from above.

In the basic mode, users A and B, as shown in FIG. It is possible to sit on the cushion 212 while leaning against the second backrest 213 (user B).

In the first reclining mode, the seat sofa portion 21 is moved forward, and its front edge portion (that is, the front edge portion 212f of the second seat cushion 212) is moved to the front edge portion 112f of the first seat cushion 112 of the couch sofa portion 11. Move to a position aligned with At this time, as shown in FIG. 3, the user B supports the second base frame 211 of the seat sofa portion 21 from below, lifts the front portion of the seat sofa portion 21, and moves the caster of the first leg portion 215a. 216 can be used to move.

In the first reclining mode, the second backrest 213 is set to the reclined position before and after the movement of the seat sofa part 21, and the second seat cushion 212 of the seat sofa part 21 and the second backrest 213 at the reclined position are positioned. Edges 212 s and 213 s are arranged so as to abut side edges 112 s of the first seat cushion 112 of the couch part 11 . In the first reclining mode arrangement, the first seat cushion 112, the second seat cushion 212 and the second backrest 213 form a continuous seating surface at the same height position.

In the present embodiment, the total value of the width dimension W1 of the first seat cushion 112 and the length dimension L2 of the second seat cushion 212 is the average height of the user (for example, male or female), as described later. It is set so that the top of the head and the heels of the user A) who has the armrest are lying down with their whole body stretched out, and neither of the first and second armrests 114 and 214 are touched.
Here, the length dimension L1 of the first seat cushion 112 is equal to or greater than the total value W2 of the width dimensions of the second seat cushion 212 and the second backrest 213 in the reclined position, and the length of the second seat cushion 212 Dimension L2 is longer than width dimension W1 of first seat cushion 112 .

The seat sofa portion 21 extends in the longitudinal direction with respect to the couch sofa portion 11. In other words, the side edges 212s and 213s of the second seat cushion 212 and the second backrest 213 extend side edges 112s of the first seat cushion 112. By arranging the seats so as to abut against each other, the distance between the two users A and B is ensured, and both users A and B can sit cross-legged on the seat surface. In the usage example shown in FIG. 4, one user A sits cross-legged on the seat surface formed by the first seat cushion 112, and the other user B is formed by the second seat cushion 212 and the second backrest 213. The seat is in a cross-legged state.
In this case, the first armrest portion 114 and the second armrest portion 214 respectively function as backrests on which the users A and B can lean.

As another example of use in the first reclining mode, the user A not only sits down, but also uses the entire convertible sofa 1 like a daybed, as shown in FIG. It is also possible to lie down from 112 to the second seat cushion 212 of the seat sofa section 21 . FIG. 5 shows a state in which the user A sleeps with his or her head directed toward the first armrest 114 of the couch sofa section 11 and her feet directed toward the second armrest 214 of the seat sofa section 21 .
It goes without saying that the user A may sleep in the opposite direction, that is, with the head directed toward the second armrest 214 and the feet directed toward the first armrest 114 . In this case, the first armrest 114 and the second armrest 214 can be used not only as an elbow rest, but also as a bed headboard when the user A lies down. , which contributes to increasing the sense of security that the user A lying down has.

In the second reclining mode, the seat sofa section 21 is separated from the couch sofa section 11 using casters 216 as shown in FIG. . Specifically, in the second reclining mode, the second backrest 213 of the seat sofa portion 21 is set to the reclined position, and the second seat cushion 212 and the side edge portion 213s of the second backrest 213 at the reclined position and The seat sofa portion 21 is rotated by 90° so that the side edge portion 212s of the second seat cushion 212 faces the front side.
Then, in the orientation after rotation, the seat sofa portion 21 is brought closer to the couch sofa portion 11, and the upper edge portion 213u of the second backrest 213 is brought into contact with the side edge portion 112s of the first seat cushion 112 of the couch sofa portion 11. to be placed.
In this case, in the second reclining mode arrangement, the first seat cushion 112, the second seat cushion 212 and the second backrest 213 form a continuous seating surface at the same height position. The seat surface formed in the second reclining mode is wider in the depth direction than the seat surface formed in the first reclining mode, and is nearly square in plan view from above.

In this embodiment, the length dimension L2 of the second seat cushion 212 is equal to or greater than the length dimension L1 of the first seat cushion 112, and the width dimension of the second seat cushion 212 and the second backrest 213 in the reclined position. Total value W2 is longer than width dimension W1 of first seat cushion 112 .

In the second reclining mode, users A and B sit next to each other as shown in FIG. , the seat sofa part 21 with the second backrest 213 laid down allows the user to stretch his/her legs and sit down. Here, the user A sitting on the couch sofa part 11 leans back on the first backrest 113, and the user B sitting on the seat sofa part 21 leans on the second armrest 214 aligned with the first backrest 113. It is possible to relax.

The convertible sofa 1 according to this embodiment has the above configuration. The effects obtained by this embodiment will be described below.

First, the couch sofa portion 11 having a first seat cushion 112 long in the depth direction, and the seat sofa portion 21 having a second seat cushion 212 having a length dimension L2 longer than the width dimension W1 of the first seat cushion 112. , and the seat sofa part 21 can be reclined to a lying position where the second backrest 213 is laid down and a standing position where the second backrest 213 is raised, so that the second backrest 213 is placed in the standing position.
