When the middle section 12 is removed, the connecting rods 14, 15 are inserted deeply into the pipe members 16, 17 facing each other. The upper part 11 and the lower part 13 are connected to each other, and the connected middle members 12 and / or 22 are attached to the protruding radius portions of the connecting rods 14 and 15 and the pipe members 16 and 17 after the connection. , So that it can be stored. In addition, in order to easily and more reliably perform the mounting, the mounting portions of the middle members 12 and 22 (portions 12a to be attached to the connecting rods 14 and 15 and the pipe members 16 and 17) have elasticity. It is good to attach by.
[0015]
FIG. 3 is a schematic structural view for explaining another embodiment of the dental treatment chair according to the present invention, and FIG. 3 (A) is a diagram when the dental treatment chair according to the present invention is used for adults (large). FIG, 3 (C) are diagrams when the children (small), FIG. 3 (B), a dental treatment chair constructed in a large adult shown in FIG. 3 (a), 3 ( FIG. 2C is a diagram of a small-sized device for a child, in which parts having the same functions as those in the example shown in FIG. 1 are denoted by the same reference numerals as in FIG. .
[0016]
Thus, in the dental treatment chair shown in FIG. 3, the middle members 12 'and 22' are formed of bag-like members which are expanded by pressurizing a fluid such as air and stored by discharging the fluid. When it is enormous, it becomes a large dental treatment chair for adults shown in FIG. 3 (A), and when the fluid is discharged, it becomes a small dental treatment chair for children shown in FIG. 3 (C). Become a chair. The upper part 11 and / or the lower part 13 of the backrest 10 are provided with spaces (recesses) 18 and 19 for accommodating the contracted intermediate member 12 ′ (similarly, the front part 21 of the contour sheet 20 and the lower part 13). And / or spaces (concave portions) 28, 29 for accommodating the contracted intermediate member 22 'are also provided in the rear portion 23), and when the fluid in the intermediate members 12', 22 'is discharged, these, middle members 12 ', 22' and are accommodated in these accommodating space, when the state shown in FIG. 3 (C), compared to the example shown in FIG. 1, a dental treatment chair It becomes very easy to handle the middle member for children. In this embodiment, as shown by a broken line in the middle member 22 'of the contour sheet portion in FIG. 3A, the middle member is one block in appearance, but one to several blocks inside. May be configured.
[0017]
The relationship between the connecting rods 14 and 15 in the backrest 10 and the pipe members 16 and 17 fitted to the connecting rods 14 and 15 is such that the connecting rods 24 and 25 in the contour sheet 20 and the connecting rods 24 and 25 are fitted. The relationship with the pipe members 26 and 27 is exactly the same. The upper section 11 and the front section 21 described above may be moved manually, but may be extended and contracted by an electric, hydraulic, or air cylinder.
