図１は、本発明に係る家具の１つであり、直方体形状の金属製筐体１０の中の、開放されている前面部を観音開き扉２２Ａ，２２Ｂによって開閉可能に構成した保管庫である。筐体は天板１２と左右の側板１４，１６と背板１８と底板２０とを具備しているが、前面部は開放されている。側板や背板は天板と一体の板金によって成形することも可能であるが、ここでは夫々天板とは独立した板金によって成形されている。従って、以下の実施例では背板１８を天板と一体形成されていない非一体板の例としているが、天板と側板１４，１６との間でも同じ接合構造が採用されている。参照番号３０は筐体前部の補強フレームであり、筐体の左右方向に延伸しつつ、天板１２の裏面に沿わせて天板を補強している。この形態の補強フレーム３０は天板１２に対してスポット溶接するが、天板に対してスポット溶接しない形態の補強フレームとすることもできる。   FIG. 1 is one of the furniture according to the present invention, and is a storage that is configured such that an open front portion in a rectangular parallelepiped metal casing 10 can be opened and closed by double doors 22A and 22B. The housing includes a top plate 12, left and right side plates 14, 16, a back plate 18, and a bottom plate 20, but the front surface is open. The side plate and the back plate can be formed of a sheet metal integrated with the top plate, but here, each of the side plates and the back plate is formed of a sheet metal independent of the top plate. Therefore, in the following embodiments, the back plate 18 is an example of a non-integral plate that is not integrally formed with the top plate, but the same joining structure is also adopted between the top plate and the side plates 14 and 16. Reference numeral 30 denotes a reinforcing frame at the front part of the housing, and the top plate is reinforced along the back surface of the top plate 12 while extending in the left-right direction of the housing. Although the reinforcing frame 30 in this form is spot-welded to the top plate 12, it can be a reinforcing frame that is not spot-welded to the top plate.

天板１２とこの非一体板１８との従来の接合構造として、図７や図８に示す形態がある。その他、図９のような形態も考えられる。然しながら、図７の形態では、外部溶接具２４Ａと内部溶接具２４Ｂによるスポット溶接は背板領域にて行われるが、背板の端部縁１８Ｅ、即ち、接合部が天板領域に現れており、特に高さの低い家具において美観を損なう。図８の場合は、接合部は天板領域には現れていないが、スポット溶接の影響によって天板の端部縁１２Ｅがその長手方向に沿って波打ち、筐体の外観が悪くなる。図９の場合は、背板１８の端部縁１８Ｅが波打ち、やはり外観が悪くなる。   As a conventional joint structure between the top plate 12 and the non-integral plate 18, there are forms shown in FIGS. In addition, a form as shown in FIG. 9 is also conceivable. However, in the form of FIG. 7, spot welding by the external welding tool 24A and the internal welding tool 24B is performed in the back plate region, but the end edge 18E of the back plate, that is, the joint portion appears in the top plate region. , Especially in low-rise furniture. In the case of FIG. 8, the joint does not appear in the top plate region, but the edge 12E of the top plate undulates along the longitudinal direction due to the effect of spot welding, and the appearance of the housing is deteriorated. In the case of FIG. 9, the end edge 18 </ b> E of the back plate 18 is waved, and the appearance is also deteriorated.

以上と異なり、本願の接合部構造は、図１の矢視線Ｂ−Ｂによる拡大断面図である図２を参照する。これは第１発明に係る一形態例を示す。背板１８の上端部を筐体の内部方向に折り曲げた背板第１折曲部１８Ｂ（第１発明における非一体板折曲部）を形成し、更に、本願では無くてもよいが、この例ではその背板第１折曲部の先部を下方に向けて折り曲げ、背板第２折曲部１８Ｃ’を形成している。一方、天板１２はその背板側端部を背板の平面に一致する下方向に折り曲げて第１折曲部１２Ａを形成し、その先部を前記背板第１折曲部１８Ｂの上面に沿うように筐体内方に折り曲げて第２折曲部１２Ｂを形成している。   Unlike the above, the junction structure of the present application refers to FIG. 2 which is an enlarged cross-sectional view taken along line BB in FIG. This shows an embodiment according to the first invention. A back plate first bent portion 18B (non-integrated plate bent portion in the first invention) is formed by bending the upper end portion of the back plate 18 toward the inside of the housing, and this may be omitted in the present application. In the example, the tip of the first bent portion of the back plate is bent downward to form the second bent portion 18C ′ of the back plate. On the other hand, the top plate 12 is bent at a back plate side end portion thereof in a downward direction corresponding to the plane of the back plate to form a first bent portion 12A, and a tip portion thereof is an upper surface of the back plate first bent portion 18B. The second bent portion 12B is formed by bending inward of the casing along

また、この第２折曲部の先部は、下方に向けて折り曲げた上下方向部１２Ｃ’と、更にその先部を折り曲げて背板の裏面に向かうように折り曲げた水平部１２Ｃとを有して第３折曲領域部を構成している。また、この第３折曲領域部の先部を背板の裏面に沿わせつつ下方に向かうように折り曲げた第４折曲部１２Ｄを形成している。この第４折曲部１２Ｄと背板１８とを、外部溶接具２４Ａと内部溶接具２４Ｂとによってスポット溶接して接合させる。   In addition, the tip portion of the second bent portion has an up-down direction portion 12C ′ bent downward and a horizontal portion 12C bent further toward the back surface of the back plate by bending the tip portion. The third bent region portion is configured. Further, a fourth bent portion 12D is formed by bending the tip portion of the third bent region portion along the back surface of the back plate and bending downward. The fourth bent portion 12D and the back plate 18 are joined by spot welding with the external welding tool 24A and the internal welding tool 24B.

以上のようにして接合させると、天板領域には接合部も、この接合のための溶接跡も現れておらず、見栄えがよい。また、背板領域に何れの側の端部縁も現れておらず、第４折曲部１２Ｄも筐体内部に位置しているため、溶接によるその端部縁の波打ちは見えず、見栄えがよい。この接合構造では、後述する図５の場合と異なり、第１折曲部１２Ａの幅（図２における上下方向寸法）が小さくて内部溶接具２４Ｂの先部が天板１２と第２折曲部１２Ｂとの間に入らない場合に特に適する。   If it joins as mentioned above, neither the junction part nor the welding trace for this joining will appear in the top plate area, and it looks good. Moreover, since the edge part of either side does not appear in a backplate area | region, and the 4th bending part 12D is also located in the inside of a housing | casing, the undulation of the edge part edge by welding is not visible, and looks good Good. In this joining structure, unlike the case of FIG. 5 described later, the width of the first bent portion 12A (the vertical dimension in FIG. 2) is small, and the front portion of the internal welding tool 24B is connected to the top plate 12 and the second bent portion. It is particularly suitable when it is not between 12B.

更には、上記例では背板第２折曲部１８Ｃ’が存在し、これに合わせて上下方向部１２Ｃ’も存在するが、背板第２折曲部が無くてもよく、この場合、実質的に上下方向部１２Ｃ’が無くて、水平部１２Ｃが背板第１折曲部１８Ｂの下側に近接していてもよい。この変形形態は図示していないが、後述の図３の構造に対する図４の構造の相違と同様である。   Furthermore, in the above example, the back plate second bent portion 18C ′ is present, and the vertical portion 12C ′ is also present in accordance therewith, but the back plate second bent portion may not be provided. Alternatively, the vertical portion 12C ′ may be omitted, and the horizontal portion 12C may be close to the lower side of the back plate first bent portion 18B. Although this modification is not shown, it is the same as the difference in the structure of FIG. 4 with respect to the structure of FIG. 3 described later.

本発明の第２形態例の図としての図３は第２発明に係る一形態を示し、図２に対応する図である。背板１８の端部を筐体内部方向に折り曲げた背板第１折曲部１８ａ（第２発明における非一体板折曲部）を形成し、更に、本願では無くてもよいが、この例ではその背板第１折曲部の先部を下方に向けて折り曲げ、背板第２折曲部１８ｂ’を形成している。一方、天板１２はその背板側端部を筐体内方に折り返して前記背板第１折曲部１８ａの上面に沿う第１折曲部１２ａを形成している。   FIG. 3 as a diagram of the second embodiment of the present invention shows an embodiment according to the second invention and corresponds to FIG. A back plate first bent portion 18a (non-integrated plate bent portion in the second invention) is formed by bending the end portion of the back plate 18 toward the inside of the housing.
