In an opposed state, it is located on the left side of the right convex portion 5c of the first shelf 5. This prevents the rear surfaces of the first shelf plate 5 and the second shelf plate 6 from abutting against each other, so that each of the shelf plates 5, 6 is divided into the partition 4 b, which is the central portion of the back plate 4, and the left and right side edges. Abutting on the part 4c,
Is ensured to occupy a predetermined position. At this time, in the first and second partial shelf receiving portions 50a and 50b, the right and left convex portions 5c, 5d, 6c and 6d of the shelf plates 5 and 6 are
The partial shelf receiving portions 50a and 50b have a length in the left-right direction at which sufficient supporting strength can be obtained, although not supported by the entire thickness of the plate. And if necessary, back plate 4
It is possible to support the right and left convex portions 5c, 5d, 6c, 6d of the shelf plates 5, 6 by utilizing substantially the entire thickness of the plate.

Next, the operation and effect of the embodiment configured as described above will be described. First and second shelves 5, 6
Is installed between the three pairs of side plates 2, 3, 3, 3 when the shelf plates 5, 6 are inserted between the pair of side plates 2, 3, 3, 3, respectively. 6, right and left convex portions 5a on both sides,
5b, 6a, 6b are the slits 41 of the step at the desired height position.
Are inserted from the front to the rear, and are supported by the shelf receiving portion 40. The right and left convex portions 5c, 5d, 6c, 6d of the rear portions of the respective shelf plates 5, 6 are formed by the slits of the side plates 2, 3. By being inserted into the first and second partial slits 51a and 51b of the same step as that of 41, the first and second partial shelf receiving portions 50a and 50b are supported, whereby each of the shelf plates 5 and 6 is A pair of side plates 2,
3, 3, and between the back plate 4. Shelves 5, 6
When adjusting the height of the shelf 5, the shelves 5, 6 are slightly inclined to release the engagement between the grooves 53 a, 54 b, 53 b, 54 a and the ridges 52 a, 52 b. , 6 are pulled out forward, so that the two convex portions 5c, 5d, 6c, 6d become the two partial slits 51a, 5d.
1b, and then the two convex portions 5a, 5b, 6a, 6b are extracted from the slit 41, and the shelves 5, 6 are removed. Then, the biconvex portions 5a, 5b, 6a, 6b of the shelves 5, 6 are inserted into slits 41 of another step at a desired height position above or below, and the biconvex portions of the shelves 5, 6 are further inserted. The parts 5c, 5d, 6c, 6d
In the first and second partial slits 51a, 51b at the same height position as the slit 41, concave grooves 53a, 54b, 53b, 54a are provided with convex ridges 52a, 5a.
The shelf plates 5 and 6 are supported by the shelf receiving portions 40 and 50 of the back plate 4 between the pair of side plates 2, 3, 3 and 3 at the new height position. You.

The projections 5a, 5b, 6a, 6b are connected to the end side plate 2
When supported by the shelf receiving portion 40, the shelf receiving portion 40 supports the convex portions 5a, 5b, 6a, and 6b using substantially the entire thickness of the end portion side plate 2, and The two shelf portions 5a, 5b, 6a, 6b of the adjacent shelf plates 5, 6 are supported side by side in the left-right direction on the shelf receiving portion 40 of the intermediate side plate 3. The two convex portions 5a, 5b, 6a, 6a, 6a, and 6b are formed by using the substantially entire thickness of the plate, in other words, each of the convex portions 5a, 5b, 6a, and 6b is approximately half the thickness of the intermediate side plate 3. Support 6b.

As a result, when each of the shelves 5 and 6 is set, the side projections 5a, 5b, 6a and 6b and the rear projections 5c and 5b are set.
d, 6c, and 6d are inserted into the slit 41 and the partial slits 51a and 51b at desired height positions, respectively, and when adjusting the height position of the shelf plates 5 and 6, the side convex portions 5a and 5d are inserted. Five
b, 6a, 6b and rear projections 5c, 5d, 6c, 6d are slit 4
1 and the partial slits 51a, 51b, and thereafter, the convex portions 5a, 5b, 6a, 6b and the convex portions are inserted into another slit 41 and the partial slits 51a, 51b at desired height positions.
Since it is only necessary to insert 5c, 5d, 6c and 6d, it is possible to set the shelves 5 and 6 and adjust the height positions of the shelves 5 and 6 in a short time. Further, since the shelf plates 5 and 6 are supported by the shelf receiving portions 40 which can utilize substantially the entire thickness of the side plates 2 and 3, the thickness of the side plates 2 and 3 Support surface 40
A sufficient supporting strength of the shelf receiving portion 40 can be ensured without increasing the thickness of the bookcase 1 and increasing the weight of the bookcase 1 without increasing the thickness of the bookcase 1.

The projections 5a, 5b, 6a, 6b of the shelves 5, 6 are supported by a shelf receiving portion 40 between the pair of side plates 2, 3, 3, 3, respectively. Of the projections 5c, 5d, 6c, 6d
Are supported by the partial shelf receiving portions 50a, 50b, so that the load due to the weight of the books placed on the shelf plates 5, 6 is increased by the convex portions 5a, 5b, 6a,
6b and the projections 5c, 5d, 6c, 6d are dispersed and supported by the side plates 2, 3 and the back plate 4. As a result, the protrusions 5a, 5b, 6
Since the load borne by a and 6b decreases, the protrusions 5a, 5b and 6
a, 6b can be reduced in the front-rear direction, so that the slit 41 forming the shelf receiving portion 40 on which the protrusions 5a, 5b, 6a, 6b are supported can be reduced in the front-rear direction. As a result, it is possible to suppress a decrease in the strength of the side plates 2 and 3 due to the formation of the slit 41.

As a result, the size of the slit 41 forming the shelf receiving portion 40 of each of the side plates 2 and 3 can be shortened, so that the strength of the side plates 2 and 3 due to the formation of the slit 41 can be reduced.
The thickness of the side plates 2 and 3 can be reduced, and the bookcase 1 can be reduced in size and weight.

Further, the shelf receiving portion 40 as a part of the side plates 2 and 3 formed by providing the slits 41 extending in the front and rear direction is formed in the same front and rear direction as the direction of the bamboo fiber forming the side plates 2 and 3. Since it extends, the shelf receiving portion 40 has a high strength due to the toughness of bamboo. As a result, the shelf receiving part 40 is
Despite being at the front edge of 3, the shelf shelf 1 is less likely to suffer damage such as chipping, and a durable bookcase 1 can be obtained. Since it has sufficient strength to support the shelves 5, 6, the minimum adjustment amount of the height position of the shelves 5, 6, that is, the degree of freedom in setting the adjustment pitch increases.

Since the direction of the bamboo fiber of the bamboo laminated timber forming the first and second shelves 5 and 6 supported on the shelf receiving portion 40 on both left and right sides is the left-right direction, the toughness of the bamboo is improved. By each shelf 5,
The residual deflection of No. 6 is extremely small. Therefore, shelves 5,
Due to the weight of the books placed on the shelf 6, the shelves 5, 6 are bent, and the shelves 5, 6 are bent in the vertical direction with the shelf receiving portions 40 located on the left and right of the shelves 5, 6 as supporting points. However, when the placed books are removed, the shelves 5 and 6 are restored to their original shapes and do not remain curved.

As a result, the first and second shelves 5, 6 hardly remain curved due to the residual bending.
Since the initial shapes of the shelf plates 5 and 6 can be maintained for a long period of time, a slit is required to secure the strength of the shelf receiving portion 40.
Even if the vertical width of 41 is set to the minimum value of the allowable range, the curvature of the shelves 5 and 6 may cause troubles such as the shelves 5 and 6 not being smoothly inserted into and removed from the slit 41. No, each shelf board 5 for the slit 41
6 can be maintained smoothly for a long time.

The concave grooves 53a, 53b, 54a, 54b of the convex portions 5c, 5d, 6c, 6d at the rear of the shelf plates 5, 6 are fitted to the partial shelf receiving portions 50a, 5
Since the shelves 5 and 6 are engaged with the ridges 52a and 52b of 0b, the protrusions 5a, 5b, 6a and 6b on the side of the shelf plates 5 and 6 are merely inserted into the shelf receiving portions of the side plates 2 and 3. Despite this, it is difficult to move forward, and the projections 5
a, 5b, 6a, and 6b are difficult to come off. As a result, the shelves 5, 6 can be stably held at a predetermined position, and the shelves 5, 6 do not move when books are moved on the shelves 5, 6, for example.

In the double bookcase 1, both partial slits 51
Since the back plate 4 provided with the a and 51b is vertically continuous at the partition 4b located between the partial slits 51a and 51b, the back plate 4 has a large number of slits 51 in the up and down direction, and Receiving part
Although the first and second shelves 5 and 6 are supported by 50, the lowering of the strength of the back plate 4 can be suppressed by the partition 4b.
As a result, even if the formation interval of a large number of slits 51 is narrowed,
The strength sufficient to support the shelves 5 and 6 is obtained, and the minimum adjustment amount of the height position of the shelves 5 and 6, that is, the degree of freedom in setting the adjustment pitch increases.

The two convex portions 5c and 5d of the first shelf 5 and the two convex portions 6c and 6d of the second shelf 6 support the respective partial shelf receiving portions 50a and 50b defined by the thickness of the back plate 4. At the same position in the horizontal direction on the surfaces 50a1 and 50b1, the protrusions 5c,
The rear surfaces of the projections 6c and 6d of the 5d and the second shelf plate 6 are not opposed to each other, and each second projection is supported by using the maximum thickness of the back plate 4 as much as possible. Is possible. As a result, even in each of the partial shelf receiving portions 50a and 50b on the same stage,
The second shelves 5, 6 are supported in a stable state by the thickness of the back plate 4, and by using the entire thickness, the thickness of the back plate 4 can be reduced. The mounting shelf can be reduced in size and weight.

The first and second shelves 5 and 6 share the one ridge 52a and 52b of each of the partial shelf receiving portions 50a and 50b of the back plate 4, so that the first and second shelves 5 Grooves of convex parts 5c, 5d, 6c, 6d
There is no need to separately provide the protruding ridges 52a, 52b with which the 53a, 53b, 54a, 54b are engaged.
It is not necessary to increase the thickness of the sheet. Further, since the first and second shelves 5 and 6 have the same specifications, the effect of mass production can be exhibited. As a result, the thickness of the back plate 4 can be reduced, and the size and weight of the bookcase 1 can be reduced. Further, the cost of the bookcase 1 can be reduced due to the effect of mass production.

The shelf receiving portion 50 provided on the single back plate 4 shared by the first and second shelf portions 5 and 6 is provided with a slit 51 penetrating through the back plate 4 like a single bookcase. As a result, in the double bookcase 1, the work volume of the shelf support 50 is the same as that of the single bookcase despite the back plate 4 having the shelf support 50. The amount of processing work for the shelf receiving portion 50 of the back plate 4 of the book shelf 1 does not increase, and the productivity of the book shelf 1 having the back plate 4 provided with the shelf receiving portion 50 is improved. Further, a back plate having the same specifications as the back plate of the single-type bookshelf can be used for the double-type bookshelf 1, whereby the cost of the bookshelf 1 can be reduced.

The two convex portions 5c and 5d at the rear of the first shelf 5 are
The rear surface of the shelf 6 is opposed to the rear surface of the second shelf 6 via a gap, and the convex portions 6c and 6d of the rear portion of the second shelf 6 are opposed to the rear surface of the first shelf 5 via the space. As a result, the rear surfaces of the first shelf 5 and the second shelf 6 are prevented from coming into contact with each other, and the
Is a partition 4b at the center of the back plate 4 and left and right side edges.
4c, the front surfaces of the respective shelves 5, 6 can be reliably occupied at predetermined positions.

Hereinafter, an embodiment in which a part of the configuration of the above-described embodiment is changed will be described with respect to the changed configuration.
In the above embodiment, since the tip of the shelf receiver 40 is located at the front edge of each of the side plates 2 and 3, there is a possibility that the shelf receiver 40 may be damaged due to contact with a hard object such as a wagon carrying books. Is not completely free. Therefore, in order to prevent such damage, a decorative member that covers the shelf receiving portion 40 from the side surface or the front surface thereof may be attached.

That is, as shown in FIG. 12 which is a perspective view showing a partially disassembled state of the bookcase 1, the entire front surface of the intermediate side plate 3 is attached to the front surface of the intermediate side surface by the connecting means 62. 3 is covered with two rod-shaped front decorative members 60 each having a width in the left-right direction that is ２ of the plate thickness. As shown in FIG. 13, the coupling means 62 includes an embedding portion 63a having a four-stage truncated cone shape, and four partial cylinders provided at intervals in the circumferential direction to form an engagement hole 63b2. Piece

And a male connector 64 made of synthetic resin that is integrally molded. Then, as shown in FIG. 14 which is a partial perspective view before the front decorative member 60 of FIG. 12 is attached to the intermediate side plate 3, the female connector 63 in which the embedded portion 63 a is embedded in the front surface of the intermediate side plate 3. A male connector 6 having an embedding portion 64a embedded in the back surface of the front decorative member 60 in the engaging hole 63b2 of the engaging portion 63b.
4 convex portion 64b is fitted, the convex portion 64b is a partial cylindrical piece 63b1
The front decorative member 60 is removably attached to the front surface of the intermediate side plate 3 by elastically engaging with the engaging portion 63b by the elastic force of.

Further, the entire outer surface of the end side plate 2 is covered with a plate-shaped side decorative member 61 which is detachably attached to the outer side surface of the end side plate 2 by the connecting means 62. Here, the female connector 63 embedded in the end side plate 2 and the side decorative member
The side decorative member 61 is detachably attached to the end side plate 2 by elastic engagement with a male connector 64 (not shown in FIG. 12) embedded in the back surface of the 61. At this time, the length of the side decorative member 61 in the front-rear direction is twice the length of the front decorative member 60 in the front-rear direction, and is longer than the length of the end side plate 2 in the front-rear direction. When attached to the end side plate 2, its front edge 61a protrudes forward from the front surface of the end side plate 2 to the same extent as the front decorative member 60.

In the bookcase 1 shown in FIG. 12, since the side decorative member 61 projects forward from the front surface of the end side plate 2, damage to the shelf receiving portion 40 due to contact with an object is prevented.
