Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a chair that also serves as a bed.

[Conventional technology]

A chair that also serves as a bed has two end plates with legs facing each other, a seat mat and a backrest that have substantially the same plane between the end plates and are connected in a hinge-like manner. In addition to being fitted, the seat mount is pulled in when the backrest mount is raised, and pushed out when the backrest mount is folded down.

[Problem that the invention attempts to solve]

Since the seat mat is pulled in and pushed out in conjunction with the upright position of the backrest mat, the structure becomes complicated and the price rises, and the heavy weight makes it difficult to handle.

There was also the problem that it could not be stored in a low volume when it was not needed.

[Means for solving problems]

In order to solve the above problems, this invention includes a first seat, a second seat connected to one side of the first seat via a flexible connecting part on the upper edge, and a second seat connected to the upper edge of the second seat. A third seat is connected to the third seat through a bendable connection part, a fourth seat is connected to the third seat through a bendable connection part at the lower edge, and a fourth seat is connected to the fourth seat through a bendable connection part at the upper edge. Narrow legs connected via connecting portions are provided by blow molding each having a hollow chamber, and a through hole is provided at the edge of the third seat on the second seat side, and a through hole is provided on the edge of the third seat on the fourth seat side. The edge of the seat is provided with a protrusion that fits into the through hole and locks when the third seat and the fourth seat are placed one on top of the other.

[Effect]

When used as a bed, the first seat, second seat,
Stretch out the third seat, fourth seat and legs into a single plate,
Lay mats or futons on top of it.

When making a chair, first stack the first seat on top of the second seat to form a seat, and then stack the bottom surface of the fourth seat on the bottom of the third seat to form a backrest. Insert the protruding pieces of the legs.

Thus, while raising the backrest, the legs are grounded to maintain the upright state of the backrest.

〔Example〕

In the figure, 1 is a first seat, and a second seat 3 is connected to one side of the first seat 1 via a bendable connecting part 2 on the upper edge. It can be folded so that it overlaps with the .

Further, the second seat 3 is provided with a third seat 5 via a bendable connection part 4 on its upper edge, and the third seat 5 is provided with a fourth seat 7 via a bendable connection part 6 on its lower edge. The fourth seat 7 can be folded so as to overlap the lower surface of the third seat 5.

Further, a narrow leg portion 9 is connected to the upper edge of the fourth seat 7 via a bendable connecting portion 8.

The above-mentioned first seat 1, second seat 3, third seat 5, fourth seat 7, and leg portion 9 are formed by blow molding having a hollow chamber.

In addition, a through hole 1 is provided at the edge of the third seat 5 on the second seat 3 side.
0 is set.

Furthermore, the edge of the leg portion 9 on the fourth seat 7 side is provided with the through hole 10 when the third seat 5 and the fourth seat 7 are overlapped.
A protruding piece 11 is provided that fits into and locks.

The protruding piece 11 described above fits within a notch 12 provided on the edge of the fourth seat 7 to prevent collision between the protruding piece 11 and the edge of the fourth seat 7.

Incidentally, an uneven strip is provided on the lower surface of each seat and the leg, and in particular, the third seat 5 and the fourth seat 7 are provided with uneven stripes.
By allowing the seats 7 to mesh with each other when stacked, the thickness of the backrest can be reduced.

The chair according to this invention has the above configuration,
When using it as a bed, as shown in Fig. 1, the first seat 1, second seat 3, third seat 5, fourth seat 7 and leg portion 9 are stretched out into a single plate shape, and then Lay mat A on.

In addition, when using it as a chair, first fold and stack the first seat 1 on the second seat 3, then raise the third seat 5, and then place the fourth seat 7 on the back of the third seat 5. Fold the fourth seat 7 so that the back sides overlap.

At this time, the protruding piece 11 is fitted into the through hole 10.

As shown in FIG. 2, when the second seat 3 and leg portions 9 are grounded (on the floor), it becomes a chair.

Further, the leg portions 9 are prevented from being reversed by the protrusions 11 that are fitted into the through holes 10 and locked, so that the backrest can be stably maintained in the upright state.

Note that the above chair uses Mat A, which was used for the bed, as a cushion.

〔effect〕

As mentioned above, according to the chair according to this invention,
It can be used as a bed by being rolled out into a single plate shape, or it can be used as a chair by folding it so that the first and second seats overlap, and the third and fourth seats respectively.

Furthermore, since each seat and leg are formed by blow molding with hollow chambers, they are lightweight and easy to handle.

Also, since the protrusion is fitted into the through hole and locked,
It is possible to prevent the backrest from turning over when used as a chair, and to maintain the upright state of the backrest.
