The pair of second hook members 10a, 10b are fixed to the pair of second side plates 7a, 7b, respectively, and are supported by the pair of first hook members 9a, 9b. The pair of hook members 9a, 9b constitute a half-slit joint.

[0017] The prefabricated furniture 1 further includes partition members 13a, 13b and ridges 14, 15. The partition members 13a, 13b are interposed between the top plate 2 and the shelf plate 4. The partition members 13a, 13b are provided with long grooves 11, 12 extending in the width direction of the top plate 2 and the shelf plate 4 in the end wall portions facing the top plate 2 and the shelf plate 4. The ridges 14, 15 are fixed to the top plate 2 and the shelf plate 4, and fit into the long grooves 11, 12.

[0018] The materials for the top board 2, base board 3, shelf board 4, first side boards 5a, 5b, second side boards 7a, 7b, and leg members 8a to 8d may be any wood that is commonly used as furniture material, such as dense wood such as cherry or maple, or heavy, hard, coarse wood such as oak, oak, or zelkova. Thinned wood such as cedar or cypress may be preferably used. By using thinned wood such as cedar or cypress, material costs can be reduced and environmental protection can be contributed. In addition to natural wood, plywood such as particle board or resin panel may be used.

[0019] The shelf board 4 is laminated on a decorative board 16 having the same shape as the shelf board 4, and is bonded, for example, by an adhesive. The material of the decorative board 16 may be, for example, lumber core plywood or particle board core plywood. Two upper edge corners located at both ends in the first direction X on the front side of the shelf board 4 are chamfered to expose approximately triangular chamfered surfaces 32a, 32b. Such chamfered surfaces 32a, 32b improve safety against inadvertent contact with the body.

[0020] Two partition plates 17a, 17b are interposed between the decorative plate 16 and the base plate 3. The partition plates 17a, 17b divide the space between the decorative plate 16 and the base plate 3 and between the pair of second side plates 7a, 7b into three storage spaces 18a, 18b, 18c. Each of the first side plates 5a, 5b is provided with a hinged door 20a, 20b by a hinge 19a, 19b. Each hinged door 20a, 20b can be angularly displaced around the axis of the hinge 19a, 19b, and closes the storage spaces 18a, 18b on both sides so that they can be opened and closed. The central storage space 18c is open, and items can be placed on the base plate 3 and stored therein.

[0021] Each of the swing doors 20a, 20b includes an upper rail member 33a, a lower rail member 34a, two vertical frames 35a, 36a, and a door panel 37a. The upper rail member 33a, the lower rail member 34a, the two vertical frames 35a, 36a, and the door panel 37a may be made of natural wood, for example. An attraction piece 38a made of a ferromagnetic material such as iron is embedded in the upper end of the free end vertical frame 35a. A permanent magnet piece 39a is fixed to the inside corner where the upper end of one of the partition panels 17a of the decorative panel 16 is joined. The attraction piece 38a is magnetically attracted to the permanent magnet piece 39a when the swing door 20a is closed, preventing the swing door 20a from accidentally opening due to the action of an impact force on the assembled furniture 1. The same attraction piece 38a and permanent magnet piece 39a are provided on the other swing door 20b, and corresponding parts are designated by the same numbers with the suffix b, and explanations will be omitted to avoid duplication. As shown in Figure 9, recesses 31a, 31b are formed on the inner surface of one of the vertical frames 35a, 35b of each swing door 20a, 20b facing the storage spaces 18a, 18b, for the user to hook his / her fingers on when opening or closing the door.

[0022] The space between the top board 2 and the shelf board 4 and between the pair of first side boards 5a, 5b is divided into three storage spaces 21a, 21b, and 21c by a pair of partition members 13a, 3b. In these storage spaces 21a to 21c, items can be placed on the shelf board 4 to be stored.

[0023] FIG. 8 is an exploded perspective view of the lower storage section 22, and FIG. 9 is an exploded perspective view of the lower storage section 22.

The shelf board 4 may be formed by joining the opposing wooden ends of three rectangular boards 4a, 4b, and 4c. The board joining method may be, for example, mutual joining or dovetail jointing.

[0024] Each of the pair of first side plates 5a, 5b may be joined by bonding two plate materials 5a1, 5a2; 5b1, 5b2 in parallel to the base plate 5a3, 5b3 with an adhesive. The interval ΔL between the two plate materials 5a1, 5a2; 5b1, 5b2 joined to each base plate 5a3, 5b3 is equal to the width B of each second side plate 7a, 7b, and the first side plate 5a, 5b having the fitting groove 6a, 6b is formed by joining each of the two plate materials 5a1, 5a2; 5b1, 5b2 to each base plate 5a3, 5b3. The interval ΔL is slightly larger than the width B to such an extent that the second side plate 7a, 7b can be fitted snugly, and the interval ΔL may be, for example, about the width B+0.1 mm to 0.2 mm. A back plate 24 is joined, for example, by adhesive to each side surface facing rearward of the base plates 5a3, 5b3, the decorative plate 16, and the base plate 3. The material of the back plate 24 may be, for example, decorative plywood.

[0025] 10 is an exploded perspective view of the top plate portion 23. The top plate portion 23 includes the above-mentioned top plate 2, a square rod-shaped reinforcing member 26 that is joined to one side edge of the top plate 2 by, for example, bonding with an adhesive, and two protrusions 14, 15. Two upper edge corners located at both ends in the first direction X on the front side of the top plate 2 are chamfered to expose approximately triangular chamfered surfaces 27a, 27b. Such chamfered surfaces 27a, 27b improve safety against inadvertent contact with the body.

[0026] The knockdown furniture 1 is placed on, for example, a floor 25 of a house. The floor 25 is not limited to the floor of a house, but may be the floor of a building such as a factory, or may be a corridor under the eaves, and may be any horizontal plane that can stably support the knockdown furniture 1.

[0027] 11A is an exploded perspective view of one second side panel 7a, and FIG. 11B is an exploded perspective view of the other second side panel 7b. The second side panel 7a located on the left side when viewed from the front of the knockdown furniture 1 is referred to as one second side panel 7a, and the second side panel 7b located on the right side is referred to as the other second side panel 7b. As shown in FIG. 11A, one second side panel 7a includes a second side panel material 7b1 made of a rectangular plate-like body and a pair of first hook members 10a bonded to one surface of the second side panel material 7b1 by adhesive. As shown in FIG. 11B, the other second side panel 7b includes a second side panel material 7b1 made of a rectangular plate-like body and a pair of second hook members 10b bonded to one surface facing the second side panel material 7b1 by adhesive.

[0028] At the upper end of one end side in the first direction X of each of the second side panel materials 7a1, 7b1, wooden pieces 28a, 28b cut into an arbitrary shape, for example a heart shape, are attached and joined with an adhesive to the cutout holes of each of the second side panel materials 7a1, 7b1 in a state where they partially protrude from the other surface of each of the second side panel materials 7a1, 7b1. Each of the wooden pieces 28a, 28b is painted with a bright red paint, for example, so that each of the wooden pieces 28a, 28b is visually emphasized against the surrounding wood grain, improving the aesthetic appearance of the design of the assembly furniture 1 and improving the affinity of the appearance of the assembly furniture 1 as a whole. Furthermore, since each of the wooden pieces 28a, 28b is provided so as to partially protrude from the other surface of each of the second side panel materials 7a1, 7b1, the worker can grasp the protruding portion of the wooden pieces 28a, 28b to insert or remove the wooden pieces 28a, 28b into or from the fitting grooves 6a, 6b of each of the second side panels 7a, 7b when assembling or disassembling the knockdown furniture 1. This improves the operability of the second side panels 7a, 7b by hand, and facilitates the insertion or removal work.
