Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bookcase, and to a so-called bookbinding bookcase.

(Prior Art) Conventionally, in a bookcase for thick bookbinding such as a dictionary, the front edge of the bookbinding, which has a shape retention plate C as shown in FIG. It is done to contact.

This is to prevent the front edge and the back of the bookbinding from flattening and losing their shape over time.

Further, in the bookbinding, the so-called ground D is above the so-called dust E, as shown in FIG.

However, in the conventional book case, the ground D hangs down with the passage of time, and the upper booklet loses its shape.
There was a problem.

In order to solve this problem, the paperboard or the like is fixed only to the portion of the inner bottom surface of the book case that should be below the ground D, and that portion is made higher than the portion below the dust E. It is proposed that D be supported.

(Problems to be Solved by the Invention) However, the conventional shape-retaining plate C has a problem that it is very easy to come off from the book case and the usability is very poor.

That is, when the upper bookbinding is pulled out from the book case, the shape retaining plate C comes off from the book case.

And when putting the shape-retaining plate C back together in the book case when putting it back in, the shape-retaining plate C becomes sideways in the book case, and the bookbinding does not fit properly, The shape-retaining plate C is turned in the opposite direction, so that the function as the shape-retaining plate is not exerted at all.

Of course, in order to avoid such a situation, everybody carefully puts the shape-binding plate C in the bookcase in the correct direction and puts on the bookbinding.

Nevertheless, the orientation of the shape-retaining plate C changes in the book case while the bookbinding is being performed.

As described above, the conventional shape retaining plate C is very difficult to use, and is often irritated during use.

Therefore, it is not uncommon for a bookbinding buyer to remove the shape retention plate C from the bookcase and dispose of it.

In addition, in order to prevent the ground D from hanging down, the above-mentioned proposal in which a paperboard or the like is fixed to the inner bottom surface of the bookcase is formed by punching the paperboard or the like separately from the bookcase to a portion that should be below the ground D. Since it has to be attached, it takes too much labor and cost to manufacture. Therefore, there is a problem that it is difficult to put it into practical use.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a bookcase, which is formed by connecting left and right side plates, a back plate, and the left and right side plates to the inside and outside of the bookcase. A top plate and a bottom plate, and upper and lower corner pieces connected to both upper and lower ends of the back plate, and a support piece sandwiched between two cut lines at a portion of the inner bottom plate near the back plate. In addition to partitioning, a cutout portion is provided on the back plate side end outside the cut line, and a lower corner piece is formed in a shape corresponding to the cutout portion and the support piece.

510 and 520 are triangular. Therefore, the notch corresponding part
90 and the support-corresponding portion 91 have a triangular shape and a rectangular shape, respectively, and the lower corner piece 9 has a shape in which a rectangle is attached to the tip of the triangle as shown in FIG.

In the present embodiment, further, small cut lines c and d are provided near the right end of the support piece 50, and the left ends of the small cut lines c and d are connected by a broken line e. The portion sandwiched between the small cut lines c and d is extended to contact the lower corner piece 9 to form a folded piece 53, and the portion of the support piece 50 outside the small cut lines c and d is locked. It is referred to as edge pieces 54, 54.

Then, a rectangular locking notch 60 is provided at the center of the left end of the inner top plate 6.

The shape-retaining plate B is wider than the back plate 2 and has a substantially rectangular edge contact plate 10.
Locking pieces 11 and 12 are provided at the centers of the upper and lower ends of the.

In assembling, first, the back plate 2 and the right side plate 3 are sequentially bent at right angles along the fold line to make the left side plate 1 and the right side plate 3 at right angles to the back plate 2, and then the folded piece along the fold line e. Fold 53 on the lower surface of the support piece 50.

Then, similarly to a normal book case, the inner bottom plate 5, the inner top plate 6, the upper gap piece 8, the lower corner piece 9, the outer top plate 4, and the outer bottom plate 7 are sequentially bent at right angles along the folding line to form the top plate portion.
