2. Description of the Related Art When a binder such as a book or a document is bound on a shelf such as a bookshelf in an upright position, a book that is not thick enough to be self-supporting, a book with a weak waist, or a large-format book, falls sideways. Since it is easy to fall (fall), in such a case,
Generally, a book stand is used.

In the book stand according to the prior art, a central portion of a metal plate is cut out in a tongue shape, and both sides of a base portion of the cutout portion are bent by press working to form a rectangular bottom plate portion and a tongue shape. In most cases, a bottom plate portion having a continuous bottom plate portion and an upright wall portion standing upright in a gate shape are integrally formed.

However, even if a book stand of this kind is used, as described above, in the case of a book that is not thick enough to be self-supporting, a book with a weak waist, or a large-format book, the force of falling sideways is added to the book stand. It is not uncommon for the bookstand to skid due to the force of the book to fall sideways. Especially many books,
The tendency becomes even stronger if they are set upright side by side.

In order to prevent such a situation, various studies have been made in the past. For example, the actual exploitation 59
-114049 gazette "a table with an anti-slip device for a mounted object", a "book stand" described in Japanese Utility Model Laid-Open No. 63-172341, a "document tipping prevention material" described in Japanese Utility Model Publication No. 60-4250, As a publicly known material, there may be mentioned, for example, "a device for attaching a middle cut plate to a steel shelf plate" described in Japanese Utility Model Publication No. 40-1764.

[0006] Among these, the "mounting table with anti-slip device" described in Japanese Utility Model Laid-Open No. 59-114049 is a non-slip sheet having a large number of projections directed obliquely on the surface and having a constant pitch. A non-slip sheet having a large number of ridges facing the same direction as the above-mentioned ridges and having the same pitch as the above-mentioned ridges is provided on the lower surface of the object to be placed, and the ridges of both the anti-slip sheets are engaged with each other. It is configured to work.

The "book stand" described in Japanese Utility Model Laid-Open No. Sho 63-172341 is provided with a locking body for locking a continuous saw blade provided on a placing surface such as a bookshelf in a state where the book stand is biased by a spring. It is composed of

The "document tipping prevention material" described in Japanese Utility Model Laid-Open No. 60-4250 has at least one rough surface, and in particular, this rough portion is composed of a sheet having point projections or small projections. , This sheet is used by laying it on each shelf of the bookshelf.

The "medium-cutting plate mounting device for steel shelf" disclosed in Japanese Utility Model Publication No. 40-1764 is a steel bookshelf in which the cuts in the front-back direction are equally spaced in the left-right direction. It is formed every time, and the lower convex portion of the book stand formed by the standing surface is inserted into this cut and used.

[0010]

SUMMARY OF THE INVENTION However, the "mounting object slip prevention device-equipped base" described in Japanese Utility Model Laid-Open No. 59-114049 and the "document fall prevention" described in Japanese Utility Model Laid-Open No. 60-4250. Since the top surface of the anti-slip sheet has many ridges and protrusions, the bottom edge of the book hits or rubs against these ridges and protrusions when the book is taken in and out. There was a problem that the lower end part of the might be damaged.

The "book stand" described in Japanese Utility Model Laid-Open No. 63-172341 and the "medium cutting plate mounting device for steel shelf" described in Japanese Utility Model Publication No. 40-1764. It can be seen that the manufacturing cost of the bookshelf itself is high due to the complicated saw-tooth-shaped irregularities formed on the inside and the double structure with the shelf plate provided in the space, and this also affects the purchase price. It is fully expected to have an impact. Moreover, since it is necessary to purchase a bookshelf having such a shelf from the beginning, there is a problem that the ready-made bookshelf that has already been purchased cannot handle it.

Since the above-mentioned conventional techniques have the above-mentioned problems, the inventor of the present invention has studied a novel non-slip technique for solving the above problems. And
As a result of earnest studies and studies thereafter, the present invention was finally created.

The present invention, which has been completed through such a process, can be used even when it is laid on a general bookshelf already owned, can be installed at a low cost without damaging books, It can handle the difference between the left and right width of bookshelves, etc.
(EN) It is an object of the present invention to provide an extremely easy-to-use anti-slip sheet that does not skid due to a lateral force applied from a book and that can prevent tilting in the horizontal rotation direction.

It is another object of the present invention to provide a shelf plate for a bookshelf having a book stand anti-slip function, which is a slippery function of the book stand provided on the shelf plate itself.

It is another object of the present invention to provide a book stand which is placed on the anti-slip sheet and the shelf plate.
