Specifically, the cam 103 is provided on the slide cam 103 so as to project from side to side. The cam protrusion 106 is in sliding contact with the cam pin 104 of the lever 101.

That is, at the folding position of the table 50, the slide cam 103 is lowered, and the cam pin 104 of the lever 101 contacts the cam projection 106. For this reason, the third lock pin of the lever 101 cannot enter the lock groove 105, and the unlocked state of the third lock means 100 is maintained.
For this reason, even if the elevating unit 40 is raised, as long as the folding position of the table 50 is maintained, the locked state of the third locking means 100 remains released.

On the other hand, when the table 50 is turned from the folding position to the unfolded position after raising the elevating unit 40, the slide hinge 52 and the interlocking bar 93 are raised, and the slide cam 103 is raised in conjunction with this.
For this reason, the cam projection 106 of the slide cam 103 and the cam pin 104 of the lever 101 are separated from each other, and the lever 101 rotates by a spring force (not shown), and the third lock pin fits into the lock groove 105. The third locking means 100 is locked and locks the lifting unit 40 in the raised position.

On the other hand, when the table 50 is turned from the unfolded position to the folding position, the slide hinge 52 and the interlocking bar 93 are lowered, and the slide cam 103 is lowered in conjunction with this.
For this reason, the cam pin 104 of the lever 101 is pushed by the cam protrusion 106 of the slide cam 103 and the lever 101 rotates. By rotating the lever 101, the third lock pin comes out of the lock groove 105,
The locked state of the third locking means 100 is released.
(how to use)

The fourth lock plate 111 is attached to the vertical frame 41 of the elevating unit 40 so as to be slidable in the front-rear direction.

Specifically, in the fourth lock plate 111, a lock groove 113 into which the second lock pin 91 of the second lock means 90 described above is fitted, and a cam groove 114 bent in a substantially S shape through which a cam pin 112 described later passes. And are provided.
Although not shown, a spring is attached to the fourth lock plate 111, and the second lock pin 91 is urged in a direction to fit into the lock groove 113. With the second lock pin 91 fitted in the lock groove 113, the fourth lock means 110 is locked, and the table 50 is locked in the folding position.

On the other hand, when a cam pin 112 described later passes through the cam groove 114, the fourth lock plate 111 slides in the direction opposite to the spring biasing direction. When the cam pin 112 passes through the cam groove 114 while the second lock pin 91 is fitted in the lock groove 113, the second lock pin 91 comes out of the lock groove 113, and the lock state of the fourth lock means 110 is released. The
For this reason, the table 50 turns from the folding position toward the unfolded position by the urging force of unfolding means (not shown) built in the rotary hinge 51.

(2) Cam pin 112
The cam pin 112 is fixed to the side rail 31 of the fixed frame 30.
The cam pin 112 passes through the cam groove 114 of the fourth lock plate 111. The cam pin 112 is set so as to pass through the cam groove 114 in a state where the elevating unit 40 is raised and the entire table 50 is exposed above the top plate 21 of the cabinet 20, and the fourth locking means 110 is set by the passage. The locked state is released.
(Temporary locking means 120)
As shown in FIGS. 17 and 18, the temporary locking means 120 is elastically brought into contact when the table 50 is turned from the folding position toward the unfolded position by the urging force of the unfolding means (not shown). The urging force of the deployment means is received.

Specifically, the temporary lock means 120 is attached to the vertical frame 41 of the lifting unit 40. The temporary lock means 120 is formed in a button shape, is attached so as to be able to appear and retract in the course of the slide hinge 52, and is elastically protruded by a spring or the like (not shown).
That is, when the table 50 is turned from the folding position toward the unfolded position by the urging force of the unfolding means (not shown) built in the rotary hinge 51, the slide hinge 52 is raised. When the table 50 is turned to the deployed position, it is locked by the second locking means 90. At this time, the slide hinge 52 abuts against the temporary locking means 120 to prevent the table 50 from going too far from the deployed position. ing.

On the other hand, in order to release the lock of the second lock means 90, the table 50 is swung upward until the deployment position is slightly exceeded. At this time, the temporary lock means 120 is retracted by being pushed by the rising slide hinge 52, The slide hinge 52 can pass over the temporary lock means 120. After passing through the slide hinge 52, the second locking means 90 protrudes again.
(how to use)
Next, a method of using the lifting device 10 according to this modification having the above-described configuration will be described.

First, as shown in FIGS. 2 and 3, in order to use the table 50 housed in the cabinet 20, the upper frame 42 (lid portion) of the elevating unit 40 is placed in the cabinet 20 through an opening (not shown). Push it a little with your hand.
When the upper frame 42 (lid part) is pushed in a little, the locked state of the first lock means 80 is released, and the spring force of the constant load spring 60 (biasing means) moves up and down as shown in FIGS. Unit 40 rises.

When the lifting unit 40 is raised and the entire table 50 is exposed above the top plate 21 of the cabinet 20, the fourth locking means 110 is unlocked.
For this reason, the table 50 turns from the folding position toward the unfolded position by the urging force of unfolding means (not shown) built in the rotary hinge 51.
The table 50 is turned to the deployed position by the temporary locking means 120 and stopped. At this time, the second locking means 90 is locked, and the table 50 is locked at the deployed position.

At the same time, the third locking means 100 is also locked, and the elevating unit 40 is locked at the raised position.
In order to store the table 50 in the cabinet 20 again after use, the table 50 may be lifted upward by hand and may be turned slightly upward until the unfolded position is exceeded.
When the table 50 is turned slightly upward, the locked state of the second lock means 90 is released. Therefore, the table 50 can be folded along the lifting unit 40 by turning downward.

When the table 50 is turned to the folding position, the fourth locking means 110 is locked again, and the table 50 is locked to the folding position.
At the same time, the locked state of the third lock means 100 is also released.
For this reason, the elevating unit 40 may be lowered into the cabinet 20, and finally the upper frame 42 (lid portion) of the elevating unit 40 may be slightly pushed into the cabinet 20 by hand through an opening (not shown).

  When the upper frame 42 (lid part) is pushed a little into the cabinet 20, the first locking means 80 is locked again, and the lifting unit 40 is locked at the lowered position stored in the cabinet 20.
