Then, the table body 2 is rotated by its own weight to the storage posture.

More specifically, when the table body 2 is rotated from the use posture to the switching posture, as shown in FIG. 8D, the projection 41b abuts on the first operation portion 43, and the stopper member 41 is moved to the first position shown in FIG. 8E. When the protrusion 41d contacts the third locking portion 47, the stopper member 41 is held in the third rotation posture and the slide member 30 moves upward. Then, the rotation of the table body 2 above the switching posture is restricted. Next, when the table body 2 is released, the table body 2 is rotated by its own weight toward the storage posture side and the slide member 30 is moved downward. At this time, as shown in FIG. 41c comes into contact with the second operation portion 44, and as shown in FIG. 8G, the stopper member 41 rotates to the reference posture rotated by 180°, 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 contacts 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 moves to the storage posture.

As described above, in this folding table 1, every time the table body 2 is moved to the switching posture by the simple operation of rotating the table body 2 to the switching posture, the storage posture along the wall surface W and the wall surface W are obtained. The posture of the table body 2 can be alternately switched to the use posture in which the table main body 2 protrudes substantially horizontally from the front. Therefore, for example, by installing the folding table 1 on the inner wall surface of a store such as a convenience store, it is possible to easily provide an eat-in space not only for a new store but also for an existing store. it can. Further, by installing the folding table 1 on the side surface of the counter of the store, the passage for the clerk arranged along the counter can be switchably utilized as the installation space of the auxiliary table connected to the counter.

In addition, although the case where the stay 4 of the present invention is applied to the folding table 1 has been described in the present embodiment, the stay 4 is applied to furniture other than the folding table 1 including an opening/closing body such as a door or a lid. Can be similarly applied.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that the configuration can be changed without departing from the scope of the present invention.
