Description

The present invention relates to a shape of a shelf-tilt additional metal fitting that suppresses a book stored on a shelf board from slipping on the shelf board due to an earthquake motion and dropping from a shelf opening.

The book shelves that are used in large numbers in university libraries, etc., are a frame part composed of a bottom part and a plurality of column parts erected from the bottom part, and a plurality of sheets arranged between the above-mentioned pillar parts inside the frame part. And a shelf board.

In order to hold the shelf board inside the frame part, a structure is often adopted in which both ends of the shelf board are fixed to the column part via fixing brackets called sleeve boards. The sleeve plate is a pair of left and right, and has a plate-shaped main body portion, a hook portion that can be engaged with an engagement hole provided in the support column portion, and a shelf plate engagement portion that engages with the shelf plate. Yes. The shelf board is usually arranged so that the upper surface for receiving a book is horizontal.

In such a shelf, when a horizontal force such as an earthquake is applied, the books on the shelf board may slide and protrude from the shelf front or fall. In order to prevent accidents caused by the fall of books during an earthquake, attempts have been made to install earthquake countermeasures on bookshelves. Examples of conventional earthquake countermeasure devices and fixing brackets for book shelves include those described in the following patent documents.

The device described in Patent Document 1 is a device that prevents a book from falling from a shelf opening by arranging a guide member in front of the book when an earthquake occurs. Patent Document 2 is a fixing bracket that inclines the shelf so that the shelf front side faces upward from the back of the shelf. By using it in place of the sleeves of the existing bookshelf, books are moved from the shelf front to the back of the shelf when an earthquake occurs. A force is applied to the book to prevent the book from falling from the shelf front.

Both technologies are effective against earthquakes, but they require a large amount of money to install a new device or replace the fixing bracket. Excluding earthquake countermeasures, it is not a useful method from the viewpoint of economic and environmental protection to dispose of the currently functioning sleeves of the existing bookshelf. In facilities with a large number of bookshelves such as university libraries, the purchase cost is high, and it is a problem that earthquake countermeasures cannot be implemented immediately.

The present invention has been made in view of such problems, and it is inexpensive to easily take measures against earthquakes by simply mounting the shelf inclined bracket of the present invention on the joint of the shelf and sleeve plates of the existing bookshelf. An attempt is made to provide a simple shelf board slant attachment.

The above-mentioned shelf inclination additional metal fittings are attached to the inside of the shelf side of the shelf front side along the bottom of the shelf board and integrated with the shelf board. By fitting the fitting holes in the bracket, the shelf is tilted so that the top surface of the shelf is an inclined surface that descends from the shelf front side toward the back of the shelf. It is a shelf inclination additional metal fitting which is given and suppresses a book falling from a shelf front.

The above-mentioned shelf inclination attaching bracket is integrated with the shelf board and engages with the claw-like projections of the sleeve board, which is a weak point of the type of bookshelf that inserts the side face of the shelf board into the sleeve board. It is a shelf inclination attaching metal fitting which vibrates and suppresses that a shelf board removes from a sleeve board, jumps out in the direction of a shelf front, or falls.
