[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is mainly applicable to an assembly box or the like assembled from a sheet material made of a paper material, a synthetic resin material, a composite material, or the like, and is adjacent to a predetermined component plate at a substantially right angle to the component plate. The present invention relates to a connecting structure for connecting right-angle adjacent plates in an assembling box or the like designed so that anyone can easily, accurately, and quickly perform an assembling operation.

[0002]

[Prior art]

 Conventionally, in an assembly box or the like assembled from a sheet-like material, when connecting two component plates that are adjacent to each other at a substantially right angle, for example, a connecting piece is connected to one of the component plates, and this connecting piece is connected to the connecting plate. A means for overlapping with the other component plate and connecting with a stapler or adhesive, or a notch in which an insert is connected to one component plate and this insert is cut into the other component plate Means for connecting by inserting into a line are employed.

[0003]

[Problems to be solved by the invention]

 However, in the former method, when the connecting pieces are overlapped on the other component plate, the connecting pieces can be connected even if the overlapping position is slightly shifted, and the assembly state varies by the operator. There was a fear. Then, inconvenience occurred in the next assembling stage, so that an assembling box having a predetermined size could not be completed. In addition, since the connecting piece overlaps the other component plate, the thickness of this portion is substantially doubled, the appearance is deteriorated, and this portion may be obstructed in the next assembling step. . Also, in the latter method, since the insertion pieces are overlapped at the cut line portion of the other component plate, the thickness of this portion is substantially doubled, and the appearance of the appearance becomes poor. In both cases, there is a possibility that this portion may become an obstacle in the next assembly stage. Further, since the insertion piece is inserted into the cut line, the cut line portion of the component plate is distorted, or the insertion piece is distorted, and stress accumulates in these portions, and the component plate itself is damaged. There was also a risk of distortion.
