It is erected. The product drop prevention frame 33 is bent about 90 degrees at both lower ends, passes through a hole 34 formed in the shelf 15, and is attached to the rotating shaft 31. As shown in FIG. 6, the product fall prevention frame 33 stands up so as to be orthogonal to the shelf board 15 so that the horizontal rail 33a abuts on the upper surface of the shelf board 15, and at the time of storage, As shown in FIG. 7, when the upper end is rotated in the direction of arrow D, the rotating shaft 31 rotates in contact with the regulating plate 30 while deforming the pressing plate 32, and the corner passes through the pressing plate 32. By the way, the product fall prevention frame 33 is pressed against the regulating plate 30 and is held in the stored state in which the product fall prevention frame 33 is parallel to the shelf board 15.

Next, the operation of the above configuration will be described.
From the state in which the shelf 15 is closed as shown in FIG. 2, the connecting member 24 is once rotated in the direction of the arrow E to release the locking pin 19 from the locking recess 29. Then, when the shelf 15 is rotated upward (in the direction of the arrow A), the support piece 23 is urged downward by its own weight and the weight of the connecting member 24, and the lower side surface portion 23 a of the support piece 23 is placed on the locking pin 19. Is placed. Subsequently, when the shelf board 15 is rotated upward, when the locking recess 25 coincides with the locking pin 19, the support piece 23 moves downward from above and the locking recess 25 engages with the locking pin 19. Stop. At this point, if the rotation of the shelf 15 is stopped, the support pieces 23
5 is urged in the direction of arrow A. In this case, the upper surface 25a of the locking concave portion 25 is locked to the locking pin 19, and the rotation of the support piece 23 in the direction of arrow B is prevented.
The shelf 15 is supported at a predetermined angle, for example, an inclination angle of 60 degrees with respect to a horizontal line.

Next, when the shelf board 15 is further rotated upward, the lower surface portion 25b of the locking recess 25 moves along the locking pin 19, and the support piece 23 is rotated in the direction of arrow B. Then, the locking pin 19 escapes from the locking recess 25 and automatically locks sequentially into the locking recess 26 disposed therebelow. Here, if the rotation of the shelf 15 is stopped, the shelf 15 is supported at a predetermined angle, for example, an inclination angle of 40 degrees with respect to the horizontal line, as described above. As described above, when the shelf 15 is further rotated upward, the locking pins 19 escape from the locking recesses 26 and are locked in the locking recesses 27, so that the shelf 15 is Supported at an angle of inclination. When the shelf 15 is further rotated upward and the locking pin 19 is locked in the locking recess 28, the shelf 15 is horizontally supported.

When the shelf 15 is closed, first, the upper end of the product fall prevention frame 33 is rotated in the direction of arrow D as shown in FIG. Next, the connecting member 24 is rotated in the direction of arrow E to

When the shelf board 15 is rotated to a position immediately below, the shelf board 15 becomes parallel to the support column 11, and the locking pin 19 engages with the locking recess 29. Here, when the shelf 15 is pulled in the opening direction, that is, in the forward direction, the upper end of the support piece 23 is also pulled in the direction of arrow C shown in FIG. However, the locking recess 29
Stops against the locking pin 19 to prevent the support piece 23 from rotating in the direction of arrow B, so that the shelf 15 stops at the position shown by the two-dot chain line and is prevented from opening further.

According to the above embodiment, the following effects can be obtained. That is, when the shelf plate 15 is rotated upward from the closed state, the locking recesses 25, 26, 27, and 28 are sequentially locked from above by the weight of the support piece 23 and the connecting member 24 from above. 19, the shelf plate 15 is held at a desired inclination angle, so that the locking shafts 5, 9 are pulled out from the locking concave portions 4, 8, and the shelves are adjusted to the inclination angle. , 9 are significantly easier to operate than in the conventional example in which two steps of locking the locking recesses 4 and 8 are performed.

2. Since the locking piece 29 is provided in the support piece 23, when the shelf board 15 is closed, the locking pin 19 engages with the locking recess 29 and the shelf board 15 is inadvertently opened. This prevents the occurrence of accidents due to the opening of the shelf 15 during movement. 3. In the above embodiment, the supporting piece 2
3 and 23 are integrally connected by the connecting member 24,
5, the support pieces 23 on both sides of the support piece 5 can be easily operated at the same time.
