As shown in FIGS. 7, 10, and 11, the retainer 91 is supported by the connecting unit 80, slides integrally with the connecting unit 80, and is rotatably supported by the connecting unit 80 via the shaft 84. It is what is done.

Specifically, a through hole 91a penetrating in the lateral direction through which the shaft 84 passes is formed in the center of the retainer 91. The retainer 91 is positioned between the inner base 82 and the outer base 83, and is rotatably supported integrally with a shaft 84 inserted into the through hole 91a.
(Slider 92)
The slider 92 is slidably supported by the retainer 91 as shown in FIGS.

Specifically, the upper portion of the slider 92 is formed in a trapezoidal shape equal to the notch 72 having a trapezoidal cross section of the panel 70.
For this reason, when the slider 92 is positioned in the notch 72 of the panel 70, the slider 92 rises and fits into the notch 72 by a biasing force of a spring 94 described later, and the slide of the table 30 stops.

When the table 30 is tilted in this stopped state, the slope on the outer surface of the upper portion of the slider 92 and the slope on the inner surface in the notch 72 come into contact with each other and are pushed by the slope in the notch 72, so that the slider 92 Falls against the biasing force of the spring 94.
When the slider 92 is lowered in the notch 72, the stopper unit 90 can be rotated around the shaft 84.
(Elevating roller 93)
As shown in FIGS. 7, 10, and 11, the elevating roller 93 is engaged with one of a plurality of recesses 73 provided in the panel 70 and functions as an elevating member.

In addition, although the raising / lowering roller 93 was illustrated as an raising / lowering member, it is not limited to this, The thing which does not use a roller may be used.
Specifically, the lifting roller 93 is rotatably supported on the upper portion of the slider 92 and slides integrally with the slider 92.
The lifting roller 93 rolls along the lower surface of the panel 70. The lift roller 93 is pressed by the lower surface of the panel 70, so that the slider 92 is always lowered.

On the other hand, when the lifting roller 93 fits into one of the plurality of recesses 73, the rolling resistance of the lifting roller 93 increases. Therefore, the slide of the table 30 is stopped and temporarily fixed at the position where the lifting roller 93 is fitted in one of the recesses 73.
To slide the table 30 again from the temporarily fixed state, the force required for the lifting roller 93 fitted into one of the recesses 73 to come out is necessary. In the normal use state of the table 30, the table 30 is not prepared. Is set not to slide.
(Spring 94)
As shown in FIGS. 7, 10, and 11, the spring 94 presses the lifting roller 93 toward the recess 73 and functions as a pressing member.

In addition, although the spring 94 was illustrated as a press member, it is not limited to this, For example, you may use elastic bodies, such as sponge.
Specifically, two springs 94 are used, and are elastically compressed between the retainer 91 and the slider 92, and the spring restoring force causes the slider 92 to move away from the retainer 91, that is, through the slider 92. The roller 93 is pressed toward the recess 73.
(Fixed roller 95)
As shown in FIGS. 7, 10, 11, and 18, the fixed roller 95 rolls along the lower surface of the panel 70 and functions as a fixed member.

In addition, although the fixed roller 95 was illustrated as a fixing member, it is not limited to this, What does not use a roller may be used.
Specifically, two fixed rollers 95 are used and are rotatably supported on the upper portion of the retainer 91.
(How to use the table storage mechanism 10)
A method of using the table storage mechanism 10 having the above configuration will be described.

First, as shown in FIG. 1, when the table 30 is slid in the upright use state, the sliding roller 86 of the connecting unit 80 slides along the rail 60.
When the table 30 is slid to the use position, the lifting roller 93 of the stopper unit 90 is fitted into one of the plurality of recesses 73 of the panel 70 as shown in FIGS. And temporarily fixed.

In order to slide the table 30 again from the temporarily fixed state, the table 30 may be slid strongly. When the table 30 is slid strongly, the lifting roller 93 is pushed against the inner surface of the recessed portion 73 in which the slider 30 is fitted, and the slider 92 descends against the urging force of the spring 94, so that the lifting roller 93 comes out of the recessed portion 73.
On the other hand, when storing the table 30, as shown in FIG. 1, the table 30 may be slid downward. When the table 30 is slid and the slider 92 of the stopper unit 90 moves to the position where the panel 70 is notched 72, the slider 92 is lifted by the urging force of the spring 94 and fits into the notch 72. The slide stops.

When the table 30 is tilted in this stopped state, the slider 92 is pushed against the biasing force of the spring 94 as shown in FIG. For this reason, when the slider 92 descends in the notch 72, the stopper unit 90 rotates around the shaft 84.
When the stopper unit 90 rotates 90 degrees, as shown in FIG. 4, the outer surface of the retainer 91 is parallel to the lower surface of the panel 70, and the rotation of the stopper unit 90 is stopped by contacting the lower surface.

That is, from the state in which the column 32 of the table 30 is upright, as shown in FIG. 1, the column 32 is turned 90 degrees around the shaft 84 to be stowed, and the top plate 31 is almost vertical. And is located approximately parallel to the footboard 22.
When the table 30 is stored, as shown in FIG. 4, when the table 30 is pushed toward the foot board 22, the outer surface of the retainer 91 of the stopper unit 90 is brought into sliding contact with the lower surface of the panel 70. It can be stored close to the footboard 22.

Even if the table 30 is to be raised in this storage position, the outer surface of the retainer 91 is in contact with the lower surface of the panel 70, so that the table 30 cannot be turned.
When the table 30 is used, as shown in FIG. 1, the table 30 may be pulled away from the head board 21 and raised.
That is, when the stopper unit 90 moves to the position of the notch 72 of the panel 70, the stopper unit 90 can be rotated as shown in FIG.

At this time, the table 30 can be caused by a relatively light force by the spring force accumulated in the mainspring 87.
When the table 30 is raised, as shown in FIG. 4, the stopper unit 90 rotates in the reverse direction about the shaft 84, and the outer surface of the retainer 91 comes into contact with the block 85 at the position rotated 90 degrees. The unit 90 stops rotating.

At this time, the urging force of the spring 94 raises the slider 92 and fits into the notch 72, so that the table 30 does not slide carelessly.
Thereafter, when the table 30 is used, as shown in FIG. 1, when the table 30 is slid in the direction of the head board 21, the slider 92 is pushed by the inclined surface in the notch 72, and the slider 92 biases the spring 94. Pressed against and descends. For this reason, the slider 30 is allowed to slide out of the notch 72 so that the table 30 can be slid.
(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG.

A feature of this embodiment is that a notch 72 of the panel 70 is provided with a closing member 100 capable of closing the notch 72 as shown in FIG.
That is, although not shown in the figure, when the table 30 is not stowed and stored and the column 32 is in an upright use state and the user wants to slide to the foot, that is, the position close to the foot board 22, the closing member 100 cuts the panel 70. The notch 72 is closed.

When the notch 72 is closed, although not shown, the stopper unit 90 passes through the position of the notch 72 and slides along the panel 70 to a position close to the foot board 22.
Although not shown, the table 30 can be temporarily fixed by providing a recess at a position passing through the notch 72, that is, near the foot board 22 of the panel 70.
Although not shown, the closing member 100 is held in the notch 72 so as to be able to appear and retract. When it is desired to pass through the notch 72, the closing member 100 is protruded into the notch 72, and is fixed at the closed position where the notch 72 is closed. On the other hand, when the table 30 is to be tilted and stored, the closing member 100 is retracted from the notch 72 and the notch 72 is opened.
