 FIG. 1 is a plan view, FIG. 2 is a sectional view taken along the line 1A-A of FIG. 1, and FIG. 1A is a plan view of the supporting rod, and FIG. 3 is a plan view of only the hard plate and the hard bone, FIG. 4 is a plan view of the hard plate without the backrest and only the hard bone, FIG. 5 is a partially cutaway rear view of the base of the supporting rod, and FIG. 6 is the same side view. FIG. 7 is a side view of a mode in which the support rod and the waist seat plate are seated on the seat chair plate with the support rod and the waist seat plate lying down as shown in FIG.

FIG. 3 is a hard chair frame 1 in which a metal seat plate 2, a U-shaped pipe outer frame 3 and an inverted U-shaped backrest frame 4 are assembled. Two reinforcing pipes 5 and 6 are passed through 3 and further both ends of the outer frame 3 are connected to both ends of the backrest frame 4 by known bending metal fittings 7 and 7 to make several fan-shaped angles and horizontal angles. One of them is selected so that it can be bent, and is connected so that it can be bent, and the chair plate 2 is placed inside the horizontally surrounded chair frame 3 and backrest frame 4, and the reinforcement pipes 5 and 6 are tacked. Stick with a kind of. The backrest frame 4 may not be used as shown in FIG. In addition, the outer frame 3 may not be used, and instead, a seat chair plate 2 having an enlarged area may be used.

Near the center of the seat plate 2 (around the upper part of the reinforcing pipe 5), the holding plates 10 and 10 on both sides, and the rear side piece 11a between the holding plates 10 and 10 are raised and the front side piece 11b. The holding plate 10, 10 is provided with a vertically elongated hole 14, and the support rod 13 is fixed with a pin 12 which is slidably fitted in the elongated hole 14. The support rod 13 has a circular or square cross section formed within the width of the holding plates 10 and 10 on both sides, and the pin 12 is fitted into the elongated hole 14 as described above. The supporting rod 13 has a height which allows a person sitting on a chair to sit on it, and is designed to be able to sway on the chair plate 2 as shown by a chain line in FIG. A shaft 16 of a waist seat plate 15 is supported at the tip of the waist support plate 15 which is supported substantially horizontally at any time. The waist seat plate 15 is supported by the top surface of the tip of the support rod 13 when the support rod 13 is erected as shown by the solid line in FIG.

The chair plate 2, the outer frame 3, and the backrest frame 4 are covered with a wrapping material 21 such as cloth or leather filled with cushioning material. The waist seat plate 15 is also covered with the wrapping material 22 which is filled with cushioning filler as described above. The support rod 13 can be covered with the wrapping material 22. The wrapping material 21 of the seating board 2 is provided with a hole 23 into which the waist seating board 15 covered with the wrapping material 22 is fitted and a crack 24 through which the supporting rod 13 is passed during ups and downs. When the wrapping material 22 covering the waist seat plate 15 is fitted into the hole 23, the wrapping material 22 has the same height as the wrapping material 21 of the seat chair plate 2 so as to prevent unevenness.

When the seat chair according to the present embodiment is not used, the supporting rod 13 which is erected as shown in FIGS. 2, 5 and 6 is lifted, and the pin 12 is raised by using the elongated hole 14 as a guide to lower the lower end of the supporting rod 13. Is shorter than the rear side piece 11a, and then recedes backward, and the supporting rod 13 is supported by the rear side piece 11a to pass through the crack 24 below the wrapping material 21 and the waist seat plate 15 wrapped in the wrapping material 22. 1 is folded in the state of FIG. 1 by fitting it into the hole 23, and when the backrest frame 4 is present, stand up as shown in FIG. 7 and sit on the wrapping material 21 in a straight seat or a cross. On the contrary to the above when using the waist seat plate 15, when the waist seat plate 15 is pulled out rearward and upward from the hole 23 and the support rod 13 is passed through the slit 24 to stand up as shown by the solid line in FIG. Lowers the lower end by its own weight between the rear side piece 11a and the front side piece 11b of the uprighting piece 11 so that the pin 12 is settled down below the long hole 14 and stands up. It is supported horizontally above the rod 13. Therefore, a person who sits on the wrapping material 21 of the sitting chair plate 2 in front of the upright supporting rod 13 or a person sitting on the cross sits down on the wrapping material 21 of the waist seating plate 15 to prevent numbness of the legs. The chair according to the present embodiment can be used for other than the case of preventing numbness.
