Description

[Detailed Description of the Invention] Industrial Field of Application This application is particularly directed to: [0] It is attached to the side wall of a fixed chair with armrests that is often installed, so that the table board can be stored vertically on the side wall surface when not in use. The present invention relates to a table board mounting device that enables the mounting of a table board.

Conventional technology Traditionally, fixed chairs with armrests installed in theaters, etc.
When not in use, the table board can be stored perpendicularly to the side wall of the chair, making it convenient for writing notes or storing personal belongings while sitting in the N seat. A device for attaching a table board to a chair that can be rotated approximately 80 degrees in a vertical position and then laid down to an inner horizontal position is known.

Problems to be Solved by the Invention However, conventionally, this type of mounting device allows the table board to be rotated 180 degrees vertically to the front position of the side wall having the armrests, and also to rotate the table plate vertically at the front position of the chair. Since the structure is provided with a protruding supporting machine m that can move up and down from a horizontal position to a horizontal position, when the table board is not in use and is housed on the outer surface of a side wall in a completely vertical position.

The support mechanism protrudes from the side wall gravity and becomes a hindrance, and
It had defects such as poor appearance and poor load resistance when the table board was laid down horizontally.

Means for Solving All Problems Therefore, the present application improves the conventional defects as described above, and the gist thereof is to provide a vertically divided portion at the outer surface position of the upper part of the side wall including a part of the armrest of the chair. A fixing member is fixed to this vertically divided portion, and on the inner surface of this fixing member,
Support 1 on the bottom of the reprint]e□. 1□6.61
□□ □ Rotatably connected and between them.

It is equipped with a regulating mechanism that restricts the rotation of the rotating member once from the unused state in which the table board is vertically installed on the side wall of the chair to the operating state in which it rotates 80 degrees, and a part of the rotating member is provided with a non-used position. The present invention is characterized in that an auxiliary piece is provided to supplement a part of the armrest portion that has been removed by forming the vertical spinning portion.

Embodiments and functions Chair A includes a backrest (1), side walls (3) provided on the left and right sides thereof and having armrests (2) at the top, a seat (4), and a backrest (1).
Preferably, the armrest portion (2) is made of a member having a decorative feature such as a wood grain pattern.

2 on the outer surface of the side wall (3) of chair A configured in this way.
The table board C is installed so that it can be rotated 180 degrees in a vertical position via the device B of the present application, and can be raised and lowered from a vertical position to a horizontal position.

As shown in Figs.
) A screw hole (8) is formed entirely in the center of the plate piece (6) so as to pass through the boss 5 (7), and a pin (9) is provided at the appropriate position on the inner surface of the plate piece (6). As shown in Figure 8.9, there is a fixing member (10) with a protruding U-shaped notch (11) on the outer periphery and a through hole (12!) in the center.
In addition, the rotating member (■ 4) and 2. The rotating member (151) is fitted onto the lower surface of the substrate (151) attached to the lower surface-corner of the table board C, and is fitted into the notch aD of the rotating member (1, 41). Fitting member (support member (I8) having 171) attached to 14J so as to be able to rise and fall freely
The fixing part 00) of the device B configured in this way is the armrest part (2) of the chair A.
A set screw (20
) to fix the plate piece (6). The inner surface of the rotating member 041 is superimposed on the inner surface of this fixing member (10) via an intervening piece +211 made of a resin ring or the like, and the inner surface of the rotating member 041 is connected to the through hole a21 provided in the fixed member (10). By screwing into the threaded hole (8) of the fixing member (10), the rotating member (14) can be rotated relative to the fixing member (10) within the range limited by the recess (13). Therefore, the table board C is rotated perpendicularly to the fixed member QOI via the two-rotation member α41.

And the rotating member (moves up and down with respect to +41).

The relationship between the recessed portion Q3 and the pin (9) is as shown in the solid line i'to and as shown in FIG. (1)
@ In the unused state where the pin (9) is stored perpendicularly to the outer surface of the wall (3), the pin (9) is in contact with one shoulder (13a), as shown by the imaginary line (A) in Figure 1 and the phantom line in Figure 4. In the operating state in which the notch circle of the rotating member (+41) faces upward and the table board C stands above the side wall of the chair A, the pin (
9) comes into contact with the other shoulder (131b), thereby regulating the rotation angle of the rotation member Q41, and adjustment of the rotation angle is performed by the adjustment screw hole (A) provided on one shoulder α3aK. .

In addition, when the table board C is not in use, a part of the rotating member Q4 is provided with an armrest that is formed when a vertically divided part is formed on the upper part of the side wall (3) in order to attach the fixed member (1 (11)). An auxiliary piece (2)a that matches the cut out part (2)' of part (2) is attached to the foot, and this auxiliary piece (2)a is attached to the armrest g, (2)
made of the same material as.

Effects of the Invention According to the present application, the table plate rotates to the operating state,
Then, when the table is laid down horizontally, the lower surface of the table comes into contact with the upper surface of the armrest. Therefore, in the use state, the load applied to the table is supported by the upper surface of the armrest, so the table has excellent load resistance. The board can be used stably, and unlike conventional methods, the mounting mechanism of the table board does not protrude from the front edge of the side wall, so it does not get in the way. By forming the armrest, a part of the notched armrest part is handled by the auxiliary part, so there is no risk of spoiling the overall appearance.
