DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 1 shows a book fixture employing a shelf support device according to the present invention, FIG. 2 is an exploded perspective view of a main part, and FIGS. 3 to 5 show a shelf support state.
Denotes a side plate, 2 denotes a shelf plate, 3 denotes a backrest member, and 4 denotes a shelf holder.

The book furniture according to the present invention is not particularly limited in its structure itself, but the one shown in the drawing is a pair of side plates 1 on the left and right sides of a display table 5 on which books can be stacked and placed on the upper surface. 1 is erected, a top plate 6 is connected between the upper ends of the side plates 1, 1 and a plurality of shelves 2,... It was done. The display stand 5 is provided with a stacker drawer 7 for accommodating books to be refilled.

More specifically, side plates 1 erected on both right and left sides
A plurality of locking holes 8, which are a pair of front and rear on a horizontal plane, are respectively formed at regular intervals in the front and rear portions on the inner surface side of 1 and a shelf receiver engaged with the front and rear locking holes 8, 8 is provided. The shelves are supported in multiple stages by the tools 4 and 4. Here, the locking hole 8 is a horizontally long oval hole in the illustrated example, and the corresponding shelf support 4 is inclined substantially parallel to the opposite side edges of the rectangular receiving piece 9 and is high in parallel. A long piece 10 having a high height and a short piece 11 having a low height are integrally formed. As shown in FIGS. 2 to 5, the shelf receiver 4 completely inserts the long piece 10 upward into the locking hole 8 and inserts the lower surface of the receiving piece 9 into the locking hole 8. At the same time, the distal end of the long piece 10 abuts against the inner surface of the side plate 1 and is attached to the side plate 1. In this state, the receiving piece 9 of the shelf receiving tool 4 is substantially horizontal, and the short piece 11 faces upward at a position protruding from the side plate 1.

In order to attach the shelf 2 to the side plate 1, the reinforcing laterally folded portions 1 formed on both sides of the shelf 2 are provided.
2 and 12 are supported on the receiving pieces 9 and 9 of the pair of front and rear shelf supports 4 and 4 mounted on the side plate 1 to receive a load.
It locks to each short piece 11 to regulate inward displacement, and further abuts the short edge 11 of the rear shelf support 4 with the front edge of the rear folded portion 13 formed on the rear edge of the shelf 2. This is done by restricting the forward displacement. Note that the rearward displacement of the shelf 2 is caused by
It is stopped by the back plate 14 provided between the rear portions of the vehicle. In the present embodiment, the depth of the shelf 2 is set to be sufficiently larger than the depth of the side plate 1, and the shelf 2 is mounted between the side plates 1, 1. The front portion is made to protrude from the side plate 1.

As described above, the structure in which the shelf plate 2 is supported by the locking holes 8,... Formed in the side plate 1 and the shelf holder 4 is the same as the conventional structure. Also, instead of the side plate 1, four columns are erected on the left, right, front and rear, and the same locking holes 8 or other shapes as described above are formed on the inner surface sides of the pair of front and rear columns. A shelf receiver corresponding to the locking hole shall be used. However, it is preferable that the vertical pitch of the locking holes 8,... Be relatively small because the angle adjustment range becomes wide in the inclined support of the shelf 2 described later.
Therefore, it is preferable that the locking hole 8 is a horizontally long hole as shown in this embodiment.

If a pair of horizontal holes like the upper shelf 2 in FIG. 3 is selected as the locking holes 8 for attaching the shelf receivers 4, 4, the shelf 2 is supported in a horizontal state. If a pair of upper and lower front sides shifted upward and downward like the lower shelf 2 in FIG. 3 is selected, the upper shelf 2 can be supported.

Then, a backrest member 3 is provided at the rear of the shelf 2.
Is mounted, and both sides of the backrest member 3 are attached to the both side plates 1, 1 by the shelf receiving members 4, 4 with the upward movement restricted.
The lifting of the rear part of the shelf 2 is prevented. Here, the backrest member 3 has a width substantially the same as the width of the shelf plate 2, and has a bottom plate 15 mounted on the shelf plate 2 at a lower end thereof, and a right angle to a front edge of the bottom plate 15. The upper back edge of the back abutment plate 16 is formed, and the upper edge of the back abutment plate 16 is further bent rearward in a substantially L-shaped cross section to form an upper edge reinforcement portion 17. Are bent rearward at substantially right angles to form side edge reinforcing portions 18, 18.
In the lower part of 18, there are formed slit holes 19, 19 which are parallel to the bottom plate 15 and open backward.

As described above, the shelf plate 2 is supported by the pair of front and rear shelf supports 4 and 4 between the side plates 1 and 1 in an upwardly inclined state. Then, a new shelf receiver 4 is attached to the locking hole 8 located above the shelf 2 in the same manner as described above, and the bottom plate 15 of the backrest member 3 is placed on the rear of the shelf 2. Thus, the shelf receiver 4 is slid rearward to receive the shelf receiver 4 in the slit holes 19, 19, thereby preventing the rear portion of the shelf plate 2 from floating. That is, the front portion of the shelf plate 2 projects forward from the front shelf support 4, and when a book is placed thereon, the center of gravity is located between the front and rear shelf supports 4, but slightly. If the load is unexpectedly applied to the front of the shelf 2 or the front of the book, the rear of the shelf 2 may be lifted. Since the slit holes 19 of the backrest member 3 placed at the rear of the rack 2 are engaged with the shelf holder 4 mounted separately from the shelf holder 4 for supporting the shelf plate 2, the lifting is ensured. Can be regulated. The angle of inclination of the shelf plate 2 can be changed depending on the number of steps of the locking holes 8 before and after the selection, so that the angle of the locking holes 8 with respect to the slit holes 19 or the angle of the shelf holder 4 also changes. Therefore, the slit hole 19
Are set slightly wide so as to absorb the change in angle.

Normally, the depth width of the side plate 1 is set to be substantially equal to or slightly wider than the depth width of a book to be stored in the side plate 1. In the case where a back support member 3 for stopping the back of the book is provided in the rear portion, the effective depth width of the shelf board 2 in front of the back support member 3 is smaller, but in the present embodiment, the depth width of the shelf board 2 is reduced. Is increased so that the effective depth width in front of the backrest member 3 substantially matches the depth width of the book, or is set slightly wider, so that the book can be stably placed even in an inclined state. . For this reason, the above-described forward bias of the center of gravity occurs, and it is important to prevent the rear portion of the shelf board 2 from floating. Note that, as shown in FIG.
It is not necessary to provide the back support member 3 in this example, but it is a matter of course that the back support member 3 may be provided.

Further, since the depth of the bottom plate 15 of the backrest member 3 is larger than the depth of the upper edge reinforcing portion 17,
As shown in FIG. 3, the shelf 2 is supported in an upwardly inclined state,
With the backrest member 3 attached to the rear part, the bottom plate 15
The upper edge reinforcing portion 17 extends to the vicinity of the back plate 14 of the book furniture. Here, when the backrest member 3 is mounted at a rear end of the bottom plate 15 at a predetermined position on a rear portion of the shelf plate 2, the shelf plate 2
A locking portion that can be locked to the rear edge of the backrest member 3 may be provided to restrict the forward movement of the backrest member 3.

[0018]

As described above, the shelf support device in the book furniture according to the present invention is a book furniture in which shelf plates are provided in multiple stages with shelf supports between side plates or columns erected on both right and left sides. A backrest member is placed on the rear part of the shelf plate, and both sides of the backrest member are mounted on the both side plates or both pillars with the shelf receiving device by upwardly moving and fixed, so that the rear part of the shelf plate rises. Even if a large downward load is suddenly applied to the shelf board or the book placed on the shelf board located ahead of the front shelf holder, the lifting of the rear part of the shelf board is ensured. This can prevent the book from being stably and safely stored.
In particular, the front part of the shelf board is made to protrude forward more than the side board,
Even when the center of gravity is shifted toward the front, the backrest member prevents the rear of the shelf from rising, and the shelf falls even if a book or the like is dropped on the front of the shelf and a sudden downward load is applied. There is nothing.

The present invention is also directed to a pair of front and rear four pillars standing upright and left and right at the front and rear portions on the inner surface side of the side plates erected on the left and right sides. A plurality of locking holes are formed at regular intervals in the up-down direction, and a shelf fixture is supported in multiple stages by a shelf receiver engaged with the front and rear locking holes. Since the shelf holder is engaged with the locking hole at the position and the locking hole at the lower position on the rear side, and the shelf plate is supported by the front and rear shelf receiving members in an upwardly inclined state, It is possible to not only use the main body of the book furniture and its shelf receiving device that can provide the conventional shelf board in multiple stages in a horizontal state, but also support the shelf board in an upwardly inclined state. If a backrest is provided at the rear of the shelf to prevent it from moving backward, It can be prevented.
