A cam surface 32 slidably in contact with the engagement pin 33 is provided at the tip of the claw 32.
b is formed and the shaft 31 to which the claw 32 is fixed
Are projected from the inner surface of the leg 1. The projecting ends of the shafts 31 of the lock mechanisms 3 of the left and right legs 1 are connected by a connecting rod 4. The connecting rod 4 has a pipe shape, and both ends 4a of the connecting rod 4 are externally fitted and fixed to the shaft 31, and an operating portion 41 for unlocking is formed at an intermediate portion thereof. Specifically, an intermediate portion of the connecting rod 4 is deformed into a mountain shape so as to be eccentric with respect to the shaft 31, and the eccentric portion is used as an operation portion 41.

In addition, between each leg 1 and the top 2, FIG.
As shown in FIG. 6, an extendable cover 5 for covering the lock mechanism 3 is provided. The cover 5 is a leg 1
A plurality of intermediate cover portions 52, 53, 54 having different sizes are interposed in a telescopic manner between a fixed cover portion 51 fixed to the upper end portion of the base plate and a movable cover portion 55 fixed to the top plate. It is configured to be pivotally supported by the shaft 23 and expand and contract in a fan shape in a side view. Movable cover part 5
The inner and outer ridges that engage with each other are formed at the end portions of the intermediate cover portions 5 and 54 and the intermediate cover portions 52 to 54. In particular,
As shown in FIG. 6, an inner ridge 55a provided at the lower end of the inner end of the movable cover portion 55 engages with an outer ridge 54b formed at the upper end of the outer end of the next intermediate cover portion 54 to engage the intermediate cover. The portion 54 is pulled up, and the inner ridge 54a protruding from the lower end of the inner end of the intermediate cover 54 engages with the outer ridge 53b protruding from the upper end of the outer surface of the next intermediate cover 53. The movable cover portion 55 and the intermediate cover portions 52 to 54 are pulled up by pulling up the next intermediate cover portion 53.
Can be developed like a fan.

Next, the operation of this table will be described.
When the top plate 2 is in the horizontal use position a, the engaging pin 33 provided on the movable bracket 22
, And the top plate 2 is locked at that position. When the operating portion 41 provided on the connecting rod 4 is pulled toward the user from this state, the claw 32 rotates from the locked position shown by the solid line in FIGS. 3 and 6 to the unlocked position shown by the imaginary line in FIG. As a result, the engagement pin 33 is separated. As a result, the locked state is released, and the top plate 2 is rotated by the urging force of the gas spring 18 to the standing standby position b as shown in FIGS. 5 and 6. Since the gas spring 18 is in the most extended state when the top plate 2 reaches the standby position b, the top plate 2 is locked at the standby position b by the presence of the gas spring 18. Therefore, a special stopper for stopping the top plate 2 at the standby position b is unnecessary. When you use the table again,
The top plate 2 is gripped and rotated to the use position a against the urging force of the gas spring 18. When the top plate 2 approaches the use position a, the engaging pin 33 moves to the claw 3 waiting at the lock position.
Abuts against the second cam surface 32b. When the top plate 2 is further pressed from this position, the engagement pin 33 slides and presses the cam surface 32a to temporarily rotate the claw 32 to the unlocked position. Then, when the top board 2 reaches the use position a,
The claw 32 self-returns to the locked position and engages with the engagement pin 33.

As described above, in this embodiment, since the cover 5 is provided between the leg 1 and the top plate 2 so as to be extendable, the lock mechanism 3 can be used regardless of the rotation position of the top plate. It can be protected so that it is not always exposed. As a result, it is possible to reliably prevent an accident of jamming a finger or the like with the claw portion of the lock mechanism 3, and to further enhance safety,
It is also possible to solve the problem that dust or the like accumulates on the lock mechanism 3 and the smoothness of operation is impaired. Ma
In addition, the intermediate cover part is configured as a telescope.
Therefore, it is possible to use a relatively hard cover
In addition to preventing the formation of gaps
Thus, safety can be further improved.

With such a configuration, a person sitting in front of the top board 2 can grasp the operation section 41 by extending his or her hand forward in the same posture. Thus, the locked state of the tabletop by the lock mechanism 3 can be released without standing up and turning around the table. Therefore, the operation for clearing the table by standing the top plate 2 can be simplified.

Further, since the top plate 2 reaches the standby position "b" at the position where the gas spring 18 is fully extended, there is no need to hit the top plate 2 against a special stopper and lock it. For this reason, it is possible to eliminate the problem of stuffing a finger, clothing, or the like with the locking portion, and to improve safety while reducing the number of components. It is needless to say that the forms of the top plate and the support elements are not limited to those in the illustrated embodiment, and that the lock mechanism can be variously modified without departing from the spirit of the present invention.
