And three holders each of which can slide along each side frame and can be fixed at an arbitrary position, three sheet supporting members serving as rods stretched between opposing holders, and between the side frames And the sheet whose upper and lower ends are held by the sheet support member.

(2) The invention according to claim 2 comprises the holder which is the component member of the chair according to claim 1, a holder main body having a hole through which the side frame can be inserted, and a holder cap screwable with the main body. The side frame is pressed by screwing the holder cap, so that it can be fixed to the side frame.

(3) The invention according to claim 3 is the chair according to

claim

1 or 2, including the seat portion made of a plate material provided with two notches for fitting the side frame.

It will be outlined with reference to the drawings how the present invention configured as described above works to solve the problem.

As shown in FIG. 1, the chair according to the present invention is configured to be able to sit by a sheet 20 which is stretched between a pair of

side frames

11 and 11 bent at both ends in the same direction, and a plate-like seat portion 30. It is Specifically, the upper end and the lower end of the sheet 20 are fixed to the sheet support member 40, while at the intermediate position of the sheet 20, as shown in FIG. Be done.

Moreover, with the movement of the holder 50 sliding on the side frame 11, the sheet support member 40 can be fixed at an arbitrary position.

Due to the construction, by changing the position of the seat supporting member 40 existing in the middle position, as shown in FIG. 1, the position of the seat portion 30 is brought to a high position, and used as a chair for an infant Or as shown in FIG. 5, by bringing the seat 30 to a lower position, it can also be used as an adult chair.

That is, the seat portion 30 is removed and the frame 10 is used in a form in which the lateral frame 12 is grounded, and the position of the holder 50, that is, the position of the seat support member 40 is set to the highest position of the holder 50 located at one end. By positioning the holder 50 at the other end and at the middle position at the bending portion 11a of the side frame 11, it is possible to form the sheet 20 in a curved shape, that is, in a cot shape over the length.

It is possible to lay the baby on the curved portion of the sheet 20.

Also, as shown in FIG. 1 and FIG. 5, the frame 10 is used upright, that is, one side of the bending portion 11a of the side frame 11 and the horizontal frame 12 bridged between the

bending portions

11a and 11a contact the floor. In the case where the seat unit 30 is used by fitting the seat unit 30 to the side frame 11, the present invention is a chair having a seat and a backrest, that is, a seated person uses the spine vertically extended, ie, eats The chair is suitable for work and work.

On the other hand, as shown in FIG. 7 and FIG. 8, when the frame 10 is used in an inverted manner, that is, used with the

horizontal frames

12, 12 in contact with the floor and the seat portion 30 is removed for use The invention makes it possible to use the whole body on the seat 20, i.e. a chair that can be relaxed and rested.
