【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. In this embodiment, a cabinet 4 including a plurality of stages of shelf boards 3 is illustrated. As shown in FIGS. 2 and 3A to 3C, this cabinet 4 is provided with a plurality of stages (three stages in this embodiment) of shelf boards 3 and drawer shelves 5, and each shelf board 3 and An upper door 6 and a lower door 7 which can be opened and closed are arranged on the front portion D of the drawer shelf 5, respectively. Each of the shelves 3 is provided with first and second bookcases 1 and 2 which are divided into front and rear. That is, the first bookcases 1 whose fronts are open are provided in the inner portions C of the respective shelf boards 3, and the respective first bookcases 1 are provided along the entire width direction B of the cabinet 4. At the front part D of the first bookcase 1, second bookcases 2 having substantially the same width dimension as the first bookcase 1 are arranged.

As shown in FIG. 1, each of the second bookcases 2 is formed in a substantially L-shaped cross section having an opening at the front and a space enough for a book to enter. It has a part 9 and both side plate parts 10, 10. The back plate portion 8 is set to have a size smaller than the vertical distance between the upper shelf plate 3 and the lower shelf plate 3, and the upper edge portion 8a of the back plate part 8 is larger than that of the upper shelf plate 3. A hinge 11 is provided on the lower portion 3a of the front surface so as to be rotatable about a horizontal axis. Therefore, the second bookcase 2 is rotatable around the hinge 11 in the front-rear direction indicated by the arrow A in a state of being suspended from the upper shelf plate 3.

Further, the bottom plate portion 9 of the second bookcase 2 is inclined upward as it goes from the back plate portion 8 side toward the front part D, and the inclination angle is centered around the hinge 11 of the second bookcase 2. The angle is set so that the book does not slip out due to the impact when it is rotated to. The side plate portions 10, 10 of the second bookcase 2 are connected to both ends of the back plate portion 8 and the bottom plate portion 9 in the lengthwise direction, respectively. As shown in FIGS. 4 and 5, a rod-shaped guide bar 12 is laid horizontally, and a partition member 13 that functions as a book end is attached to the guide bar 12. The partition member 13 is formed in a frame shape bent into a substantially U shape or a substantially U shape, and a base end portion 13a thereof is slidably fitted in the guide bar 12 and a free end portion 13b thereof is a bottom plate portion. The partition member 13 is mounted so as to be able to come into contact with and separate from the member 9 so that the partition member 13 can move along the guide bar 12. Further, as shown in FIG. 6, for example, a cap 14 made of a material having a large frictional resistance is attached to the free end portion 13b of the partition member 13 to prevent the free end portion 13b from being worn. Good.

On the other hand, the frame plates 4a and 4b of the cabinet 4 are provided with a pair of left and right stoppers 15 projecting inward as shown in FIGS. It is arranged so as to face both end portions of the back surface of the back plate portion 8 of the second bookcase 2. These stoppers 15 prevent the second bookshelf 2 from rotating more unnecessarily rearward from the hanging state due to the hinge 11.

In the above-mentioned configuration, the second bookcase 2 arranged at the front part D of the first bookcase 1 is rotatably hung vertically on the lower front part 3a of the upper shelf plate 3 via the hinge 11. Therefore, for example, it is possible to open the first bookshelf 1 in the back part C by simply rotating the second bookshelf 2 forward with the hinge 11 with one hand, and in this state, with the other hand. The books can be smoothly taken in and out of the first bookshelf 1. Therefore, although the second bookshelf 2 is set to have substantially the same dimensions as the first bookshelf 1, unlike the conventional case where the front bookshelf is slid laterally, the first bookshelf is slid. There is no risk that the second bookshelf 2 will get in the way when loading and unloading books from 1 and the problem that the second bookshelf 2 is subject to dimensional restrictions is solved, and the space used by the entire shelf can be increased. It will be possible.

Further, in this embodiment, the base end portion 13a of the partition member 13 is movably fitted into the guide bar 12 which is horizontally installed in the inner portion of the second bookcase 2, and the free end portion 13b of the partition member 13 is also fitted. Since the bottom plate portion 9 is in contact with the bottom plate portion 9, when the partition member 13 is pressed against a book, the free end portion 13b of the partition member 13 contacts the bottom plate portion 9 so that the partition member 13 cannot move easily. In addition to the function as a book end, the partition member 13 can be gripped by hand to rotate the second bookshelf 2. Further, the second bookshelf 2 is not only suspended by the hinges 11, but also the bottom plate 9 of the second bookshelf 2 is inclined forward and upward, and further fixed to the cabinet 4 side on both sides of the back plate 8. Since the pair of stoppers 15 are arranged, stable storage of the books in the second bookshelf 2 can be achieved, and the second bookshelf 2 cannot be rotated backward more than necessary. It is possible to prevent the books from jumping out in the front, and the functions of the bookshelf can be fully exerted.

In the above embodiment, the back plate 8 of the second bookshelf 2 is hung on the upper shelf 3 via the hinge 11, but the back 8 is attached to the upper shelf 3. The hinge 11 is not limited to the hinge 11 as long as it has a function of dynamically supporting it. Further, the structure other than the back plate portion 8, for example, the both side plate portions 10, 10 may be pivotally supported by the upper shelf plate 3.

[Effect of device]

 As described above, according to the first aspect of the invention, the first bookcase whose front is opened is provided in the inner part of the plurality of shelves, and the front is opened in the front part of the first bookcase. The second bookshelf is arranged, and the second bookshelf is vertically rotatably provided on the lower part of the front surface of the upper shelf plate. Therefore, the second bookshelf is rotated forward to move the first bookshelf to the first shelf. It is possible to eliminate the problem that the second bookshelf is subject to the dimensional limitation as in the past, since there is no danger of hindering the loading and unloading of books from the bookshelf. As a result, it is possible to set the book shelves at both the back and the front of the shelves to almost the same size, which has the effect of ensuring a large space for using the shelves as a whole.

According to the second aspect of the present invention, a guide bar extending in the lateral direction is arranged in the inner part of the second bookcase, and the partition member is slidably arranged along the guide bar. Further, by pressing the partition member against the book, not only the function as the book end is obtained, but also the function as the handle when the second bookcase is rotated is obtained.
