<Third Embodiment>
FIGS. 13 (a) to 13 (c) show the configuration of the assembly furniture according to the third embodiment of the present invention, and FIGS. 14 (a) to 14 (d) show the assembly according to the embodiment. This will be described in detail with a focus on the shape of the fixed portion of the furniture.

  As shown in FIG. 13A and FIG. 14A, the assembly furniture 30 according to the third embodiment includes a flat plate 31, two side plates 32 and 33, and a frame 34. A fixed portion 35 that protrudes inward and is rotatable with respect to the frame 34 is formed at the lower end of the straight portion fitted to the side plates 32 and 33 of the U-shaped frame 34. A through hole is provided at the bottom of the side plates 32 and 33 so that the rotating part of the frame 34 can penetrate inside. The fixing portion 35 is rotatable as shown in FIG. 13B, and fixes the frame 34 to the side plate 32 in a state as shown in FIG. 13C.

  That is, as shown in FIG. 14B, the fixing portion 35 includes a rotating flat plate portion 35 a and a shaft portion 35 b for rotatably mounting the rotating flat plate portion 35 a to the lower side of the frame 34. Consists of. As shown in FIG. 14 (c), the fixing portion 35 is positioned so as to be horizontal with the longitudinal direction of the frame 34, and after fitting the frame 34 into the concave portion of the side plate 32, FIG. If rotated as shown in d), the frame 34 can be fixed in a state in which it does not come off from the recess of the side plate 32.

  The first to third embodiments of the present invention have been described above. However, the present invention is not limited to this, and various improvements and modifications can be made without departing from the spirit of the present invention.

  For example, the shape of the wedge that integrally fixes the side plate and the frame is not particularly limited, and various shapes can be adopted. Further, the recess for fitting the frame is not limited to being formed in the substantially central portion of the side plate or the like, but can be formed in various places, and the number is not limited to one. . Further, in addition to the concave portions of the side plate, the number of frames is not limited to that described above. For example, when the table itself becomes large and it is desired to increase the strength, it is needless to say that not only the center one frame but also two or three frames can be distributed.

  Further, as shown in FIG. 15, even if the positional relationship between the frame, the side plate, and the flat plate of the assembly furniture according to the first embodiment is reversed, it is possible to assemble with the same mechanism. That is, the first straight portion 54 a and the second straight portion 54 b of the frame are fitted in the recesses provided on the inner surfaces of the side plates 52 and 53, respectively, and the third straight line of the frame 54 is fitted in the recess provided on the upper surface of the flat plate 51. It is good also as what is called a top plate winning structure so that the part 54c may fit. It goes without saying that reversing the relationship between the side plate win and the top plate win similarly in the relationship with the second embodiment.
