に対して起伏動作する。 As shown in FIGS. 6 and 7, the device B of the present application has a boss portion 7 integrally provided on the outer surface of the central portion of a partially cut disk-shaped plate piece 6, and a boss portion 7 that extends through the boss portion 7. A fixing member 10 has a screw hole 8 formed in the center of the plate piece 6, and a pin 9 protruding from the inner surface of the plate piece 6 at a suitable position, and a U-shape on the outer periphery as shown in FIGS. A notch 11 with a through hole 12 in the center.
and a rotating member 14 formed with an arc-shaped recess 13 on the inner surface that allows movement of the pin 9 and has shoulders 13a and 13b at both ends that abut the pin 9.
A fitting member is attached to the lower surface of the substrate 15 attached to one corner of the lower surface of the table board C, and is fitted into the notch 11 of the rotating member 14 and is attached to the rotating member 14 by a pivot 16 so as to be able to rise and fall freely. 17, and a support member 18 having a support member 17, and the fixing member 10 of the device B configured in this way is partially vertically mounted at an upper position of the side wall 3 including a portion 2a of the armrest 2 of the chair A. At the outer surface position of the vertically divided portion 19 formed by dividing,
It is fixed by fixing the plate piece 6 with a set screw 20. The inner surface of the rotating member 14 is superimposed on the inner surface of the fixing member 10 via an intervening piece 21 made of a resin ring or the like, and the connecting shaft 22 is inserted through the through hole 12 provided in the fixed member 10, and the threaded end portion 23 of the rotating member 14 is inserted into the inner surface of the fixed member 10. By screwing into the screw hole 8 of the fixed member 10, the rotating member 14 can be rotated within the range limited by the recessed part 13.
is rotatably attached to the fixed member 10,
Therefore, the table board C rotates perpendicularly to the fixed member 10 via the rotating member 14, and
It moves up and down against the ground.

The notch 11 of is positioned downward and the table board C is
When the pin 9 is not in use and is housed vertically on the outer surface of the side wall 3 of the rotary member 14, the pin 9 comes into contact with one shoulder 13a, and the pin 9 contacts the notch of the rotating member 14 as shown by the phantom line A in FIG. 1 and the phantom line in FIG. In the operating state in which the section 11 is positioned upward and the table board C stands above the side wall of the chair A, the pin 9 abuts the other shoulder section 13b, thereby regulating the rotation angle of the rotating member 14. The rotation angle is adjusted by an adjustment screw 24 provided on one shoulder 13a.

する。Effects of the Invention As described above, according to the present application, in the use state in which the table board rotates to the operating state and then lies down to the horizontal state, the lower surface of the table board comes into contact with the upper surface of the armrest, and therefore, in the use state, Since the load applied to the table board is supported by the upper surface of the armrest, it has excellent load resistance, allowing stable use of the table board, and does not require the table board mounting mechanism to protrude from the front edge of the side wall, unlike in conventional systems. Therefore, this does not get in the way, and when the table board is not in use, a part of the armrest part cut out by forming the vertical part is covered by the auxiliary part, so it does not spoil the appearance. It has advantages such as no worries.
