As shown in FIGS. 1 to 3, in the storage shelf 1 according to the present embodiment, placed objects B (in the present embodiment) to be placed on the respective shelf plates 22 are placed above the upper front end portion and the lower front end portion. , documents indicated by phantom lines in FIGS. 3 and 5) are arranged along the width direction of the storage shelf 1 as a fall prevention member for preventing the fall.

In this embodiment, the fall prevention bar 24 provided on the upper shelf 22u and the fall prevention bar 24 provided on the lower shelf 22d are configured similarly. For this reason, the drop prevention bar 24 provided on the lower shelf 22d will be described below, and a detailed description of the drop prevention bar 24 provided on the upper shelf 22u will be omitted.

As shown in FIGS. 5 to 7, the fall prevention bar 24 is attached to the lower shelf 22d via the support member 23. As shown in FIGS. Both ends of the fall prevention bar 24 are fixed to upper ends of connecting portions 24b, which are plate-shaped members. A retaining portion 24a and an insertion portion 24c are fixed to the lower end of the connecting portion 24b. As shown in FIGS. 5 to 7, the support member 23 erected on the lower shelf plate 22d has a long hole 23a. By inserting the insertion portion 24c into the long hole 23a, the fall prevention bar 24 is connected to the support member 23 and attached to the lower shelf plate 22d.

The drop prevention bar 24 can be vertically displaced by displacing the insertion portion 24c inside the elongated hole 23a. The drop prevention bar 24 can be displaced between a drop prevention position that prevents the placed object B from falling and an open position that is positioned forward of the drop prevention position and the lower shelf plate 22d. Specifically, as shown in FIG. 3, the support member 23 is formed with a locking portion 23b which is a concave portion. A state in which the anti-drop bar 24 is housed in the locking portion 23b is the anti-drop position, and when the anti-drop bar 24 is positioned at the anti-drop position, the object B can be prevented from falling.

On the other hand, as shown in FIG. 5, when the user of the storage shelf 1 lifts the fall prevention bar 24 above the engaging portion 23b, the fall prevention bar 24 is displaced forward as indicated by the arrow in FIG. becomes possible. Then, as indicated by the phantom line in FIG. 5, the drop prevention bar 24 can be displaced to the drop prevention position and the open position positioned forward of the lower shelf plate 22d. When the fall prevention bar 24 is positioned at the open position, it becomes easier for the user to put in and take out the placed object B. As shown in FIG.

As described above, the drop prevention bar 24 moves between the drop prevention position and the open position as the insertion portion 24c moves up and down inside the long hole 23a and rotates about the insertion portion 24c together with the connecting portion 24b. It is possible to displace between The structure of the fall prevention member is not limited to the present embodiment, and it is possible to employ an electric control method as a structure for displacing the fall prevention member between the fall prevention position and the open position. be.

In the storage shelf 1 according to this embodiment, as shown in FIGS. 1 to 3, the slide panel 31 is arranged displaceably behind the fall prevention bar 24 in the fall prevention position in the space above the lower shelf board 22d. It is Therefore, the drop prevention bar 24 located at the drop prevention position does not interfere with the slide panel 31 when it is pivotally displaced to the front open position. As a result, in the storage shelf 1, the slide panel 31 that shields the inside of the lower shelf plate 22d and the fall prevention bar 24 that can be displaced forward and backward can coexist.

In the storage shelf 1 according to this embodiment, the forward bent portion 31b formed in the lower portion of the slide panel 31 is positioned below the fall prevention bar 24 in the fall prevention position as shown in FIG. The dimension D of the gap between the front bent portion 31b and the upper surface of the lower shelf 22d is the upper limit of the amount of deflection of the upper shelf 22u allowed in the JIS standard (JIS S 1039:2005) (in this embodiment, is 0.5% of the width of the upper shelf plate 22u). As a result, even if the upper shelf 22u bends downward and the slide panel 31 is displaced downward, the forward bent portion 31b does not interfere with the lower shelf 22d, thereby inhibiting smooth displacement of the slide panel 31. can be prevented.

In this embodiment, as shown in FIG. 3, when the fall prevention bar 24 is positioned at the fall prevention position, the retaining portion 24a is positioned at the same height as the front bent portion 31b of the slide panel 31 in side view. Therefore, when the retaining portion 24a is covered with a resin cushioning material, it is possible to reduce the contact noise when the slide panel 31 is displaced and comes into contact with the retaining portion 24a.

5, the lower bent portion 31c (lower end portion of the slide panel 31) formed at the front end portion of the forward bent portion 31b of the slide panel 31 is located on the front side of the lower front end portion (the front end of the lower shelf plate 22d). front side of surface 22a). By arranging the downward bent portion 31c on the front side of the lower shelf 22d in this manner, the rearward movement of the slide panel 31 is restricted by the front end surface 22a of the lower shelf 22d. The forward movement of the slide panel 31 is restricted by a fall prevention bar 24 located at the fall prevention position or the open position as shown in FIG.

In this embodiment, as shown in FIGS. 4 and 5, a lubricating member 31d made of a resin tape is attached to the rear surface of the lower bent portion 31c, which is the surface facing the front end surface 22a. In this way, the downward bent portion 31c and the front end surface 22a are prevented from being scratched by the structure in which they are not in direct contact with each other. Further, smooth displacement of the slide panel 31 can be realized by the lubricating member 31d.

Further, as shown in FIG. 5, the length dimension H of the portion of the downward bent portion 31c located below the upper surface of the lower shelf plate 22d is within the limits of the lower shelf plate allowed by the JIS standard (JIS S 1039:2005). It is formed with a vertical width dimension larger than the upper limit value of the bending amount of the plate 22d (in this embodiment, the length that is 0.5% of the width dimension of the lower shelf plate 22d). As a result, even when the lower shelf 22d is bent and displaced downward, it is possible to prevent a gap from being formed between the lower side of the lower bent portion 31c and the lower shelf 22d. The front end portion of the side shelf plate 22d can maintain a state of restricting rearward movement.

In addition, in the storage shelf 1 according to this embodiment, the fall prevention bar 24 is attached to the lower shelf board 22d via the support member 23, as shown in FIGS. As a result, the drop prevention bar 24 can be pre-assembled to the lower shelf plate 22d before the storage shelf 1 is assembled, thereby simplifying the work at the installation site of the storage shelf 1.

Further, if the fall prevention bar 24 and the support member 23 are assembled to the shelf bracket 21, the fall prevention bar 24 and the support member 23 must be removed when the lower shelf 22d is attached or detached. However, in this embodiment, the fall prevention bar 24 and the support member 23 are attached to the lower shelf plate 22d. This eliminates the need to remove the fall prevention bar 24 and the support member 23 when attaching and detaching the lower shelf 22d. That is, it is possible to easily attach and detach the lower shelf plate 22d.
