This enables space-saving and high-density storage. Further, even when the bed has a low floor, the handle portion 28 does not project to the bottom side and does not rattle during use.

Further, the leg portion 40 may have any configuration as long as it can be folded on the back surface of the seat portion 20. Here, an example of the leg portion 40 suitable for the present invention will be described. The leg portion 40 suitable for the present invention is configured by, for example, a substantially U-shaped metal pipe whose convex side is rotatably fixed to the seat frame 22. Further, a shaft 42a is fixed to the base side of the leg portion 40 so as to bridge the front and rear leg portions 40, and the convex side of a substantially U-shaped link 42 is rotatably connected to the shaft 42a. A slide shaft 42b is fixed to the base side of the link 42 so as to bridge it, and the slide shaft 42b is slidably held in a slit 46 provided in the seat frame 22. A stopper groove for locking the standing state of the leg portion 40 is formed at the outer end of the slit 46. Further, a leg stopper 44 abuts on the slide shaft 42b, and the elastic force of the leg stopper 44 locks the slide shaft 42b between the inner folding position and the standing position fitted in the stopper groove. The user can unlock the leg 40 when it is standing up by removing the slide shaft 42b from the stopper groove.

Then, when standing the leg portion 40, the user rotates the leg portion 40 in the opening direction. As a result, the front side of the link 42 is pulled by the shaft 42a, and along with this, the base slide shaft 42b slides toward the outer standing position. As a result, the link 42 makes a predetermined angle with the seat frame 22. Then, when the slide shaft 42b reaches the outer end, the slide shaft 42b falls into the stopper groove and reaches the standing position. Then, the leg stopper 44 locks the slide shaft 42b at this standing position. As a result, the leg portion 40 is fixed in a standing state. Further, when the leg portion 40 is folded, the user removes the slide shaft 42b from the stopper groove and rotates the leg portion 40 in the closing direction. As a result, the front side of the link 42 is pressed by the shaft 42a, and accordingly, the base slide shaft 42b slides toward the inner folded position. As a result, the link 42 is pulled toward the seat frame 22 side and becomes substantially parallel. Then, when the slide shaft 42b reaches the folding position, the leg stopper 44 locks the slide shaft 42b at this position. As a result, the leg portion 40 is fixed in the folded state.

The auxiliary leg 50 is also not particularly limited, but the distance between the ground contact surface and the backrest surface 30a and the contact surface between the ground contact surface and the seat surface when the auxiliary leg portion 50 and the leg portion 40 are in the folded state and the standing state, respectively. It is formed in such a size that the distance to 20a is equal. As a result, the auxiliary leg portion 50 and the leg portion 40 are well grounded in both the high bed type and the low bed type, and the bench bed 80 can be used in a stable state without rattling.

Here, as the configuration of the auxiliary leg portion 50 suitable for the present invention, for example, the auxiliary leg portion 50 is formed of a wire or a metal plate having a substantially U-shape, and both end sides thereof are the grounding ends in the case of the low bed type. After being bent in a mountain fold, it is bent in a direction parallel to the short side of the backrest portion 30 to form a rotation axis. Further, an auxiliary leg fixing plate 52 having a slit for restricting the rotation of the auxiliary leg part 50 and a shaft hole raised in the vertical direction is fixed to the backrest frame 32, and the rotation shaft of the auxiliary leg part 50 is fixed. The (bent end) is fitted into the shaft hole through the slit of the auxiliary leg fixing plate 52, and is pivotally connected to the backrest portion 30. Further, a stopper groove 54 for locking the auxiliary leg portion 50 in a standing state is formed in the slit of the auxiliary leg fixing plate 52, and the edge of the slit connected to this stopper groove 54 is slanted so that the stopper groove 54 side is narrowed inward. Has been formed. Then, when the auxiliary leg portion 50 is to be erected, the user rotates the auxiliary leg portion 50 in the opening direction. As a result, the base side of the auxiliary leg portion 50 bends and advances along the oblique edge, and falls into the stopper groove 54 at the point beyond the apex. As a result, the auxiliary leg portion 50 is locked in the standing state. When folding the auxiliary leg portion 50, the user bends the base portion of the auxiliary leg portion 50 inward and removes it from the stopper groove 54. As a result, the locked state of the auxiliary leg portion 50 is released. Then, the auxiliary leg portion 50 is folded by rotating the auxiliary leg portion 50 in the closing direction. Since the elastic force acts on the auxiliary leg portion 50 toward the outside, the diagonal edge portion does not move toward the stopper groove 54 in a natural state.

Furthermore, position-decided Me means includes a folded form of angle is 0 ° the bearing surface 20a and the back rest surface 30a as described above, the bed form of angle is 180 °, the angle is 90 ° to 120 It can be fixed in at least three chair forms. It should be noted that the angle of the backrest surface 30a in the chair form may be a specific one of 90° to 120°, or may be a plurality of angles that allow reclining in multiple stages. In this example, an angle of the backrest surface 30a in a chair form is 95°.
