Ri consists 10 Prefecture, stringer-shaped receiving space formed inside
You. Each of the above members is configured to be freely assembled and disassembled.

The lid 2 is pivotally attached to the front edge of the upper frame 10 via pivoting members 14 (such as hinges). At the center of the rear edge of each of the right lid 3 and the left lid 4 of the lid 2, a lid 2 is provided.
Handles 11 and 11 for facilitating opening and closing are provided. The handle 11 is configured so as to be out of the way according to the open / closed state of the lid 2 and to be swingable so that it can be easily opened and closed. Further, the lower frame 5 has wheels 12 and 12 fixed to the front and rear ends in the center in the left-right direction, and the column member 6 has wheels 13... Easy.

Next, the order and method of assembling the sofa bed will be described with reference to FIGS. FIG. 4 shows the lower frame 5. The lower frame 5 includes a substantially rectangular frame portion 5a including four frames and the like, and a bottom portion 5b stretched inside the frame portion 5a. The bottom portion 5b includes a net portion 15 in which a metal bar is formed in a net shape, and a reinforcing support strip plate 16 provided at the center in the left-right direction over the front and rear to reinforce that the net portion 15 is bent by the stored items. (The wheels 12 are attached to the front and rear ends of the lower surface of the reinforcing support strip 16. )

Next, as shown in FIG. 5, the lower ends of the column members 6 are fixed to the corners of the lower frame 5 with bolts or the like. As shown in FIG. 6, the wall plates 7 are inserted into the insertion grooves 6a, 6a of the column member 6 respectively on the left and right side surfaces of the sofa bed.
It is inserted and supported so that it becomes two sheets each of the front and rear surfaces.
And the reinforcing member 9 having the upper opening-shaped hole 9a is
In order to integrally connect and reinforce the front two wall plates 7, 7 and the rear two wall plates 7, 7, the wall plates 7,.
To be fixed.

FIGS. 7A and 7B are explanatory views of a structure in which the wall plates 7, 7 are inserted into and supported by the column member 6. FIG. 7A is a plan view of the vicinity of the insertion portion, and FIG. FIG. The column member 6 has outer supporting strips 17 and 17 and inner supporting strips 18 and 18. An insertion concave groove 6a is formed by the outer supporting strip 17 and the inner supporting strip 18 and a groove bottom surface 19 connecting them. You. The wall plate 7 is provided with the insertion groove 6a.
Is inserted from above and below and is supported.

Next, as shown in FIG. 8, the upper frame 10 to which the lid 2 is pivotally attached is fixed to the upper end of the column member 6 with bolts or the like. The upper end of the column member 6 is covered with a column cover 20 made of soft plastic, rubber, or the like so that the upper end of the column member 6 is not injured.

Reference numeral 8 denotes a center support rod. The center support rod 8 has insertion portions 8a, 8a at the front and rear ends of the lower surface, the insertion portions 8a having a shape corresponding to the holes 9a of the reinforcing member 9.
Is the hole 9a (of the reinforcing member 9) (the reinforcing member 9 and the hole 9a).
See FIG. ).
As mentioned above, the sofa bed of the present invention is assembled,
It can be broken down by the reverse order. Central support rod 8
Is configured to be detachable in an assembled state.

FIG. 9 shows a second embodiment. That is, a center support pipe 21 is used as the center support member instead of the center support rod 8 in the first embodiment.
(A) is a plan view, (B) is a side view, and (C) is G
-G sectional enlarged view is shown. At the front and rear ends of the lower surface of the central support pipe 21, the same structure and role as those of the insertion portion 8a shown in FIG. 8 described above (that is, a shape corresponding to the hole 9a and inserted into the hole 9a). An insertion portion 21a is provided vertically.

Further, an auxiliary plate 2 for assisting the support of the lid 2
2 and 22 are fixed to the pipe 21 by welding or the like so that the uppermost surface height thereof is substantially equal to the upper surface height of the pipe 21 (see FIG. 9C). It is preferable that covers are attached to both ends of the pipe 21.

FIG. 10 shows the third embodiment.
Is a cross-sectional side view of the main part, and (b) is a front view (or rear view) of the main part.
Is shown. That is, the front and back of the sofa bed are each 1
It consists of a number of wall plates 7. FIG. 10 shows only the center part in the left-right direction.

On the inner surface of the sofa bed, a plate-like reinforcing member 23 composed of a vertical portion 23a and a horizontal portion 23b connected to the lower end of the vertical portion 23a has a vertical portion 23a on the wall plate 7 and a horizontal portion.
23b are fixed to the reinforcing support strip 16 with bolts or the like. A reinforcing member 24 is fixed to the outer surface of the storage bed by bonding or the like. That is, the wall plates 7, 7 on the front and rear surfaces of the storage bed are reinforced from the inner and outer surfaces by the reinforcing members 23, 23, 24, 24.

FIG. 11 shows a fourth embodiment. That is, the ratchet built-in support rods 25, 25 are provided near the left and right side surfaces of the sofa bed. That is, one end (lower end) of the support rod 25 is pivotally connected to the wall plate 7 on the right or left side of the sofa bed, and the other end (upper end) is part of the lower surface of the seat 2b of the lid 2 (however, left and right). It is connected to the side. Support rod 25
Is configured and arranged so as to be able to expand and contract by opening and closing the lid 2 stepwise or steplessly, and to prevent the lid 2 from being opened more than necessary.

In the present invention, the design can be changed,
For example, the right lid 3 and the left lid 4 may be integrated, and the lid 2 may be formed as a single piece. Further, the bottom 5b of the lower frame 5 may be formed in a plate shape.

[0022]

Since the present invention is configured as described above, the following effects can be obtained.
