Claims

[Claims for Utility Model Registration] In a frame that is assembled into a frame by interconnecting adjacent parts of the peripheral edge of a board with a punched center part, a notch is provided in one of the adjacent peripheral edges, and An engaging tongue is provided upright within this notch, and a retaining tongue that engages with the engaging tongue is provided at a corresponding portion of the other peripheral edge, and a retaining tongue that engages with the engaging tongue is provided in the vicinity of the retaining tongue. A groove is provided in which the engaging tongue piece is allowed to enter, and the engaging tongue piece is bent against the peripheral edge and inserted into the groove, and then the engaging tongue piece is folded back to its original position. A frame characterized in that it has an assembly structure in which the tip of the engagement tongue is engaged with the inner surface of the locking tongue and both peripheral edges are connected.
