Further, the slide member 30 pushes the piston rod 51a of the soft absorber 51 downward and holds it in a contracted state.

Next, when the posture of the table body 2 is switched from the storage posture to the use posture, the table body 2 is rotated by hand from the storage posture shown by the solid line in FIG. 5 to the switching posture shown by the virtual line. 6, the table body 2 can be held in a substantially horizontal use posture.

More specifically, as shown in FIGS. 4 and 8A, the rotation of the stopper member 41 is restricted by the front plate portion 24b of the lower sound deadening plate 23 and the upper reinforcing plate 24 from the storage position to just before the switching position. , the slide member 30 moves upward along the guide hole 22a while the stopper member 41 is held in the reference position. However, when the table body 2 is operated to the switching posture, as shown in FIG. 8B, the projection 41a on the upper rear portion of the stopper member 41 comes into contact with the first operating portion 43, and the stopper member 41 is rotated in the first rotation. After the stopper member 41 is rotated to the moving posture, the projection 41b on the upper front portion of the stopper member 41 abuts on the first locking portion 45 and is held in the first rotating posture. At this time, the upward movement of the slide member 30 is restricted, and the rotation of the table body 2 above the switching position is restricted. Next, when the table body 2 is operated from the switching posture to the use posture, as shown in FIG. When the stopper member 41 rotates to the second rotation posture, the protrusion 41c on the lower rear portion of the stopper member 41 comes into contact with the second locking portion 46, and the stopper member 41 is locked in the second rotation posture. The downward movement of the slide member 30 is restricted, and the table body 2 is held in the use posture. In addition, the piston rod 51a of the soft absorber 51 is sequentially moved along with the upward movement of the slide member 30 by an internal return spring (not shown) until the table body 2 is rotated about 45 degrees from the retracted posture. After extending and rotating the table body 2 by about 45° from the retracted posture, it is held in the most extended state as shown in FIG.

Next, when the posture of the table body 2 is switched from the use posture to the storage posture, the table body 2 is first rotated to the switching posture shown by the phantom lines in FIG. Then, the table body 2 rotates to the retracted posture due to its own weight.

More specifically, when the table body 2 is rotated from the use posture to the switching posture, as shown in FIG. 3, and the protrusion 41d abuts against the third locking portion 47, the stopper member 41 is held in the third rotation posture, and the upward movement of the slide member 30 is locked. is stopped, and rotation of the table body 2 above the switching position is restricted. Next, when the hand is released from the table body 2, the table body 2 rotates by its own weight toward the retracted posture, and the slide member 30 moves downward. At this time, as shown in FIG. 41c contacts the second operation portion 44, and as shown in FIG. 8G, the stopper member 41 is rotated by 180° to the reference posture, and the stopper member 41 is held in the reference posture. Further, when the table body 2 is at an angle of about 45° with respect to the horizontal, the lower end of the slide member 30 comes into contact with the piston rod 51a, and the downward movement of the slide member 30 is decelerated by the soft absorber 51. In this state, the table body 2 is moved to the retracted posture.

As described above, in the folding table 1, by a simple operation of rotating the table body 2 to the switching posture, each time the table body 2 is operated to the switching posture, the stored posture along the wall surface W and the wall surface W are changed. The posture of the table body 2 can be alternately switched between the use posture protruding substantially horizontally forward from the table body 2 . For this reason, for example, by installing this folding table 1 on the inner wall surface of a store such as a convenience store, it is possible to provide an eat-in space in an existing store as well as in a new store. can.
