  However, the conventional fall prevention device may be anything that is assumed to be installed from the design stage, but to use it on an existing shelf that is not initially planned for installation of the fall prevention device, the following is required. There was a serious problem. That is, in the aspect represented by Patent Document 1, such as screwing on the front surface of the support, it is necessary to newly provide a mounting hole and screw it. In such a configuration, for example, like a library, the number of shelves themselves is enormous, and considering that they must be attached to each shelf board, installation work takes time and is easy to use. I could not say.

  Moreover, in the technique installed in the engagement hole for adjusting the height of the shelf provided in the column represented by Patent Document 2, it is not necessary to newly provide a mounting hole as in Patent Document 1. In addition, it cannot be used for shelves that do not have engagement holes in the support columns, and the shape of the engagement holes is not necessarily uniform, so there are problems in terms of compatibility and versatility. .

  In particular, the above work is usually performed with all the books on the shelf removed from the shelf, but such operations should be performed where there are numerous books such as libraries. Is not realistic from the viewpoint of workability. In addition, when opening holes on site, the shelf is often made of thin steel, and processing noise is generated during processing and steel scraps are generated. There was also a situation where on-site processing of local products should be avoided.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and the object of the present invention is to ensure that the articles mounted on the shelves of the shelf are not disengaged even by large shaking or vibration. An object of the present invention is to provide a fall prevention device that can be held and can be easily installed on an existing shelf.

Further, the plate-like body forming the front plate 13A and the side plate 13D and the plate-like bodies forming the hook member 13B and the installation plate 13C are connected by welding.

  The front plate 13 </ b> A is formed in a vertically long shape at the same level as the width of the fixing member 12 on the front side. The hook member 13B is formed by bending an end portion of a plate-like body forming the installation plate 13C into a U-shape in the bottom surface direction. Since the hook member 13B is hooked on the back side of the shelf board R and fixes the entire fall prevention device 1 to the shelf board, the size of the U-shape is the shape on the back side of the shelf board R. Relied on and adjusted accordingly.

  The installation plate 13C is in contact with the shelf plate R in the depth direction of the shelf plate R and plays a role of assisting the fixing of the fall prevention device 1 to the shelf plate R in the hook member 13B. In the present embodiment, in order to secure the contact and fixing of the installation plate 13C to the shelf plate R, for example, as shown in the figure, a double-sided tape T is placed between the installation plate 13C and the shelf plate R. Is inserted. The side plate 13D has a substantially triangular shape when viewed from the side, and plays a role of assisting the shape and strength of the fixing member 12 and the fall prevention device 1 as a whole, and the side of the shelf plate R when the fall prevention device 1 is installed on the shelf. It also plays a role of facilitating positioning such as arranging the side plate 13D in contact with the support column at the end (see FIG. 2).

  The attachment member 13 is basically installed at both end portions of the shelf plate R, and the sizes of the hook member 13B, the installation plate 13C, and the side plate 13D are adjusted in accordance with the size of the shelf plate R in the depth direction. In addition to the determination, the length of the fall prevention basket 11 is determined according to the width of the shelf board R.

[1-2. Effect]
Regarding the action of the fall prevention device 1 having the above-described configuration, FIG. 1, FIG. 2 showing a state in which the fall prevention device 1 is installed on a shelf board, and FIG. 3 showing a shelf in which the fall prevention device 1 is particularly provided. The description will be given with reference.

  From the state shown in FIG. 1, the double-faced tape T is affixed to the back surface of the installation plate 13 </ b> C of the mounting member 13, and the hook member 13 </ b> B is first hooked on the back surface of the shelf plate R at both side ends of the shelf plate R. Next, the installation plate 13 </ b> C is installed along the depth direction of the shelf plate R and fixed by the adhesive force of the double-sided tape T. This state is shown in FIG.

  The fall prevention tool 1 is installed in the right and left both sides of the shelf board R by the above operations. As shown in FIG. 2, the fall prevention device 1 is configured such that the fall prevention rod 11 is pivotally supported by the shaft fixing portion 12 </ b> A of the fixing member 12, and the upper position from the lower position (indicated by a two-dot chain line in the figure). The fixed portions 11C provided at both end portions of the recumbent rod 11A are fixed and used by being inserted into the opening 12B of the fixing member 12.

  As shown in the image diagrams of FIGS. 2 and 3, by providing the fall prevention tool 1 on the outstanding shelf R constituting the shelf C, the book B mounted on the shelf R can be shaken by the influence of an earthquake or the like. When it is going to fall to the near side in the figure by vibration, the fall can be prevented by the horizontal bar 11A of the fall prevention bar 11.

  2 and 3, the book mounted on the shelf board R tends to fall to the front side in the figure, so that the direction of the force applied to the fall prevention basket 11 is also the front side in the figure. At this time, since the hook member 13B is hooked on the back side of the shelf board R, the hook member 13B has a strong structure against the force acting in the front side direction of the shelf board R.

  According to the fall prevention tool 1 of this embodiment as described above, by mounting a pair of mounting members 13 provided with hook members 13B on both sides of the shelf board R, work such as drilling is not required.
