The bookshelf 1 described above has the above configuration, so when the bookshelf 1 is used, the books to be stored are sequentially arranged on the shelf board 36. side plate 26, top plate 29, back plate 32,
Since the exterior body 3 such as 32', 33, 33' and the shelf board 36 is attached to cover most of the frame body 2 from the outside, most of the exterior parts except the partition plate 35 are made of wood. This makes it possible to maintain an extremely beautiful appearance compared to metal bookshelves. Also,
As shown in FIG. 3, the bookshelf 1 is constructed by appropriately adjusting the support bolts 9 of the base 5 with respect to the floor surface 7 to bring the base 5 into a horizontal state, and then attaching the exterior body 3 to the frame body 2. are all supported by the frame 2, and the total weight of the books arranged on the shelf board 36 is also transmitted and supported to the frame 2 via the partition plates 35 that support the shelf boards 36, respectively, so it is also strong in terms of strength. Extremely robust;
In terms of durability, it can demonstrate the same performance as a metal bookshelf. In addition, since it has a mixture of metal and wood parts, it can be made lighter than a metal bookshelf of the same size, and it is also possible to use inexpensive materials such as flash wood for the wood part. , it becomes possible to manufacture the bookshelf 1 at low cost. Furthermore, since metal core members 36b and 36b' are installed in the width direction of the shelf board 36 that directly supports the books, this effectively prevents the shelf board 36 from bending downward due to the weight of the books. can be prevented. In addition, the position of the shelf board 36 can be freely changed by changing the engagement height position of the partition board 35 with the columns 11 and 12 with the shelf board 36 removed, so the size of the books to be stored can be changed. It is possible to immediately respond to changes in the bookshelf 1, which is highly mobile and versatile. On this occasion,
Since each partition plate 35 engages with the engagement hole 11a of the support column 11 separately, even if there is a partition plate 35 supporting an adjacent shelf plate 36 at the same height position of the same support column 11, there will be no problem. The partition plate 35 can be engaged without any interference. Furthermore, partition plate 3
5 supports the shelf board 36 and can also play the role of partitioning the books arranged on the shelf board 36 at regular intervals, so there is no need to use special bookends for partitions, etc., and the bookshelf 1 is configured. It becomes possible to reduce the number of parts.

Note that the engagement means between the shelf board 36 and the partition board 35 are as follows:
Any configuration may be used as long as the shelf board 36 is mounted on the partition board 35 in a horizontally fixed state. For example, a protrusion may be planted on the shelf board 36 side, and a receptacle corresponding to the protrusion may be used. Of course, a hole may be formed in the portion 35b, and the protrusion may be fitted into the hole of the receiving portion 35b.

Note that the top plate joining device of the present invention has the above-mentioned support column 1.
1 and 12 with only the leg parts 11b and 12b, and can also be used as a bookshelf that can be freely installed near a wall by providing the shelf board 36 only on one side of the pillars 11 and 12. Can adapt.

Furthermore, it is also possible to use the unit furniture as a joining device for the top plates of furniture that is used by sequentially connecting them laterally as necessary; in this case, the partial top plate in the middle part has two A substantially T-shaped fitting groove 29b is formed in the end surface of the holder.

As explained above, the furniture top board joining device of the present invention connects the approximately T-shaped fitting groove 29b formed on the mating end surfaces of the partial top boards to be joined together to the protruding part of the upper surface of the furniture frame. Since the part 11' and the left and right halves of the elongated joint member 22 formed in the width direction of the top plate are fitted and joined, the work of joining the partial top plates on site is facilitated. This has an excellent practical effect in that the abutting joint surfaces of the above-mentioned partial top plates do not shift.
