The second protruding portion 165 protrudes from the overhang portion 163 in the thickness direction of the back plate 20, and is further formed by bending its front end in a substantially L-shape toward the inside in the width direction of the case 10. . The bent portion of the tip of the second protrusion 165 inserted from the outside to the inside of the bottom plate 26 is hooked on the inner surface of the bottom plate 26. 6, the end of the contact piece 461 on the back plate 20 side is inserted between the second protrusion 165 and the first side plate 24, as in the case shown in FIG. The tip of the projection 165 bent in a substantially L-shape is constantly pressed in a direction in which the projection 165 is hooked on the bottom plate 26, and is prevented from falling out of the rectangular hole 202 without permission. In the vicinity of the end of the abutment piece 461 of the fixing tool 46 on the back plate 20 side, as shown in FIG. Two projecting pieces 463 having surfaces are formed. The two projecting pieces 463 sandwich the second projecting portion 165 from both sides in the same manner as shown in FIGS. By doing so, the displacement of the fixture 46 is prevented, so that the first projection 164 and the second projection 165 are securely fixed by the fixture 46.

A long hole 243 is formed near the end of the first side plate 24 on the lid plate 28 side, as shown in FIG. A circular hole 403 is formed at a position overlapping the long hole 243 of the second side plate 40. The long hole 243 has a longer diameter than the long hole 402. Further, each of the above-described long holes 401, 402, and 243 is formed to extend in an arc along the locus of the position where each long hole is formed when the gusset 42 expands and contracts. On the other hand, a concave portion 166 is formed in the cover body 161 of the cover member 16 at a position corresponding to the long hole 243 and the circular hole 403. The recess 166 serves as a passage for the fastener 48 when the gusset 42 expands and contracts.

The fastener 48 is inserted into the circular hole 403 and the elongated hole 243 as shown in FIG. The fastening tool 48 has a disk-shaped overhang and a rod-shaped shaft, and is formed by, for example, integrally fitting a convex male member 481 and a ring-shaped female member 482. The projecting portion of the anchor 48 is at least larger than the minor diameter of the long hole 243 and the diameter of the circular hole 403 in order to prevent the anchor 48 from being pulled out of the circular hole 403 and the elongated hole 243 without permission. It is formed. At the time of assembly, the male member 481 is inserted from the outside of the circular hole 241 to the inside. The female member 482 is fitted to the tip of the male member 481 protruding inside the long hole 243. The length of the shaft portion of the fastening tool 48 is formed to be slightly longer than the total thickness of the first side plate 24 and the second side plate 40 superimposed.

The one-piece member 44 is bent at the hinge line 22 and abuts on the bottom plate 26. The cover plate 26 is bent at the hinge line 22 so as to cover the article storage opening 50. At this time, the top plate 30 and the front plate 32 are bent at the hinge portion 22 into a substantially L-shape. When the case 10 is closed, the front plate 32 is overlaid on the front plate 34 as shown in FIG. As shown in FIG. 2, the stopper 18 can be separated into two parts. One member is fixed to the front plate 34, and the other member is fixed to the front plate 32 of the lid plate 26. By fitting the projection 18a of one member into the recess 18b of the other member, the cover plate 26 covers the article storage opening 50 and is fixed to the front plate 34 in a closed state.

In this case 10, when the gusset 42 is contracted, the second side plate 40 is stored between the first side plate 24 and the cover member 16. When the user extends the gusset part 42, the second side plate 40 slides and is pulled out by pulling the front plate 34 toward the near side away from the back plate 20 as shown in FIG. The state changes from the state shown in FIG. When the user contracts the gusset portion 42, the front side plate 34 is pushed into the back side plate 20 side, whereby the second side plate 40 is slid in the opposite direction to the above and stored, and the state shown in FIG. The state shown in is shown. That is, the first side plate 24 is always fixed to the back plate 20, while the second side plate 40 is movable. The second side surface plate 40 of the case 10 draws a fan-shaped trajectory with the lower end in the height direction as a fulcrum. Therefore, the long hole 401 on the lower end side in the height direction is formed as a short arc-shaped long hole, and the long hole 243 on the upper end side is formed as a long arc-shaped long hole. Then, the shaft of the fastening tool 48 comes into contact with the end of the long hole 243, and the shaft of the first projections 164, 164 comes into contact with the ends of the long holes 241, 242, whereby the second side plate is formed. The slide 40 is restricted, and the gusset 42 does not extend any further.

In the case 10, the first side plate 24 and the second side plate 40 are overlapped in their thickness direction and slidably engaged to form the gusset 42, so that the second gusset 42 is formed. The gusset 42 can be expanded and contracted by sliding the side plate 40 with the first side plate 24. Therefore, documents can be easily taken in and out of the article storage opening 50. Further, since the cover member 16 is attached to the outside of the first side plate 24, the elongated hole 243 is not exposed to the outside when the gusset 42 is contracted. Further, since the elongated hole 243 is formed in the first side plate 24, even when the second side plate 40 is slid and pulled out to extend the gusset 42, the elongated hole 243 is formed on the cover member 16. Do not expose to the outside. Therefore, the case 10 of this embodiment is not only functional but also sophisticated in design and beautiful in appearance. Further, the first protrusion 164 and the second protrusion 165 of the cover member 16 can be simultaneously fixed by one fixing tool 46, and the hook member 162 of the cover member 16 can be fixed to the first side surface. Since the plate 24 and the second side plate 40 are simultaneously held, the number of components can be reduced.

[0026]

[Effect of the invention]

 According to the present invention, it is possible to obtain a case in which the gusset part can be expanded and contracted and documents can be easily taken in and out. In this case, since the gusset portion is expanded and contracted by sliding the second side plate, the thickness of the gusset portion can be reduced compared to, for example, a bellows-shaped one, and the appearance is also beautiful.
