  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The article pop-out prevention device (1) according to the present invention is a long object attached along the front edge (2b) of the shelf board to the shelf upper surface (2a) on which the article is placed. The side wall surface (1a) facing the back side of the wall and the bottom surface (1b) contacting the shelf top surface (2a) are flat surfaces (FIGS. 1 and 2). By making the side wall surface (1a) of the article pop-up prevention tool (1) flat, it eliminates the risk of damage to the article even when the article comes in and out of the side wall surface, and makes the bottom surface (1b) flat. It is easy to fix and adhere to the top surface of the shelf. Moreover, by making the article pop-out prevention tool (1) a long object that can be cut, it can be easily attached to shelf boards of various widths while adjusting the length.

  The article pop-out prevention device (1) is fixed with the bottom surface (1b) abutting against the shelf top surface (2a), but the fixing method is not particularly limited, and adhesives, nails, spirals, etc. are used. Although it can be fixed, it is preferable to attach the bottom surface (1b) of the article pop-out prevention device (1) and the top surface (2a) of the shelf board (2) with a double-sided tape because the attachment work becomes easy. As shown in Fig. 8, if the double-sided tape (4), one side of which is covered with release paper (5), is attached to the bottom (1b), the release paper can be removed and the adhesive tape exposed when used. By adhering the surface to the top surface of the shelf board, the article pop-out preventing tool can be easily fixed.

  If the side wall surface (1a) of the article pop-out prevention device (1) is perpendicular to the bottom surface (1b), when the book is placed on the bookshelf, the back cover of the book is relatively close to the side wall surface of the article pop-up prevention device. Since the contact is made in a wide area, the book can be prevented from jumping out from the bookshelf without damaging the book.

  As shown in FIG. 1, the article pop-out preventing device (1) can have an L-shaped cross section (FIG. 1 (a)) or a right triangle (FIG. 1 (b)). With such a shape, it becomes possible to continuously extrude the article pop-out prevention tool, and to mold the side wall surface (1a) and the bottom surface (1b) into a flat surface while improving the production efficiency. it can.

  When the vertical cross section of the article pop-out preventing tool is L-shaped, it can be attached so that the side wall (1c) is positioned in the vicinity of the front edge (2b) of the shelf as shown in FIG. By attaching the article pop-out prevention tool (1) in this way, even if the book shelf has a small depth dimension, the book can be placed on the top surface of the shelf board without the article pop-out prevention tool getting in the way.

  The side wall surface (1a) of the pop-out prevention tool ensures that articles such as books will not fall off the shelf in the event of a shake such as an earthquake. It needs to be. From these things, it is preferable that the height of the side wall surface of an article | item pop-out prevention tool is 7-10 mm.

  FIG. 3 (front view) and FIG. 4 (side view) show a state in which the article pop-out prevention device (1) is installed and a book is placed on the shelf board upper surface (2a). When a shake such as an earthquake occurs, the book (3) moves on the shelf board (2a), but the back cover (3a) is the side wall surface (3a) placed on the back side of the shelf of the article pop-up prevention tool (1) ( Contact with 1a) prevents the book from moving and prevents the book from jumping out of the bookshelf (FIG. 4).

  In addition, as shown in FIG. 5, when the book rotates around a fulcrum P at the lower end of the back cover (3a) of the book (3) due to strong shaking such as an earthquake, the upper end angle of the book Since the part comes into contact with the upper shelf board (2), the rotation of the book is restricted, and the book does not fall from the shelf board. Even if the upper shelf is not installed, if the center of gravity (G) of the book does not rotate until it exceeds the upper extension line (L) of the fulcrum P, the book will be rotated by the rotational moment due to gravity. The book does not fall off the shelf because it returns to its original position.

  Furthermore, as shown in FIG. 6, even when the book (3) gets over the article pop-out prevention tool (1), the center of gravity of the book is more than the extension line (L) extending upward from the upper end Q of the side wall surface (1a). If (G) is located on the back side of the bookshelf (corresponding to the right side in the figure), a rotational moment due to gravity acts with the upper end Q as a fulcrum, so that the book does not fall off the shelf.

  Even if the book (3) falls down on the shelf as shown in FIG. 7, it is possible to prevent the book from falling if a part of the book is in contact with the side wall surface (1a) of the article pop-out prevention tool. it can.
