In the stage box of the present invention, a first plate-like body corresponding to a top plate, a second plate-like body corresponding to a bottom plate, and four side plates located between the first plate-like body and the second plate-like body are continuous. By using two types of frame side plates having different thicknesses, it is possible to form a lightweight inset type stage box and a heavy laminated stage box. That is, the lightweight fitting type stage box uses a thin frame side plate, the upper end of the frame side plate is fitted into the first peripheral groove formed on the back surface of the first plate-like body, and the lower end of the frame side plate is the first. It is obtained by fitting it into the second peripheral groove formed on the upper surface of the two-plate-shaped body. The thin frame side plate is preferably made of resin.

In the stage box of the present invention, the heavy laminated stage box uses a thick frame side plate having a specific inner peripheral dimension, and the thick frame side plate is placed upright on the upper surface of the second plate-like body. , Obtained by placing the first plate-like body on the frame side plate. In this case, since the frame side plate is arranged outside the corner protrusions formed on the first plate-shaped body and the second plate-shaped body, the three parts of the frame side plate, the first plate-shaped body, and the second plate-shaped body are A stable stage box can be formed without shifting. As the thick frame side plate, a cardboard-shaped paper material is preferable. Thereby, various printings for sales promotion can be applied to the surface of the frame side plate.

In order to form such two different types of stage boxes, on the frame side plate side of the first plate-shaped body and the second plate-shaped body, a groove wall forming the first peripheral groove and the second peripheral groove and a corner are formed. The protrusions are formed in a specific positional relationship. Further, the same thing can be used for the first plate-shaped body and the second plate-shaped body, and in this case, one of them is turned upside down or used as it is without being turned upside down.

Next, the stage box in the first embodiment of the present invention will be described with reference to FIGS. 1 to 10. The stage box 10 is a laminated stage box with a large weight, and has a first frame side plate 1 formed of four first large side plates having a predetermined thickness and a first plate shape attached to the upper end of the first frame side plate 1. It is a laminated body of the body 2 (top plate) and the second plate-shaped body 3 (bottom plate) attached to the lower end of the first frame side plate 1. In this example, the first plate-shaped body 2 and the second plate-shaped body 3 are the same, and the second plate-shaped body 3 is used upside down.

In the stage box 10, the first plate-shaped body 2 has a top plate portion 21c and four first side plates 21 (21a, 21a, 21b, 21b), and the back surface of the first plate-shaped body 2 is downward. It is formed at four corners inside a predetermined dimension (t ₂ ) from the first peripheral groove 22 having a groove width (t ₁ ) extending along the first side plate 21 and the inner wall 221 forming the first peripheral groove 22. It has a first corner protrusion 23a extending downwardly. The "four corners" mean four corners of a virtual square inner wall formed inside a predetermined dimension (t ₂ ) from the inner wall 221 forming the first peripheral groove 22. The groove width (t ₁ ) is substantially the same as the thickness (t ₁ ) of the first frame side plate 1, and is usually about 3 to 10 mm. The plan view of the first plate-shaped body 2 is a quadrangle (rectangle), and therefore, the plan view shape of the first peripheral groove 22 is also a quadrangle (rectangle) in a plan view corresponding to the shape of the first plate-shaped body 2. be.

Further, on the back surface of the first plate-shaped body 2 (FIGS. 4 and 6), the first corner protrusion 23a is separated from the inner wall 221 forming the first peripheral groove 22 by a dimension (t ₂ ) of about 2 to 8 mm in the side direction. Is formed. In this example, the outer wall of the first peripheral groove 22 is the first side plate 21 (21a, 21a, 21b, 21b). Therefore, the dimension w in the side direction from the outer peripheral surface of the outer wall of the first side plate 21 to the first corner protrusion 23a is ((t ₁ ) + (t ₂ ) + the thickness of both walls forming the first peripheral groove 22. ), Which is about 8 to 20 mm, and this portion is a contact surface with which the upper end surface or the lower end surface of the thick first frame side plate 1 in the laminated stage box 10 of this example abuts. That is, this contact surface is a band-shaped quadrangle having a width w in a plan view, and includes a virtual surface (groove portion) that does not actually exist.

In the first plate-shaped body 2, the groove depth of the first peripheral groove 22 is about half the height of the outer wall of the first side plate 21. That is, between the first side plate 21 and the inner wall 221 having the same height as the first side plate 21 formed inside the first side plate 21, a partition wall 223 for partitioning the upper and lower parts is formed at an intermediate position in the height direction, and the back half thereof. Is the first peripheral groove 22, and the front half thereof is a locking groove (third peripheral groove) 26 into which the frame side plate is fitted when forming another stage box.

In the first plate-shaped body 2, since the first corner protrusion 23a is formed at the corner portion, the plan view shape is L-shaped, and in the vertical direction, the side view is below the lower end of the first side plate 21. Extends to. This makes it possible to regulate the lateral movement of the thick frame side plate 1. That is, the length (protruding length) from the lower end of the first side plate 21 (21a, 21b) of the first corner protrusion 23a may be several cm. It is preferable that the tip of the first corner protrusion 23a is cut horizontally so that the first plate-shaped body 2 can be stably placed on an installation surface such as a floor when the first plate-shaped body 2 is turned upside down and used. .. In this case, the first corner protrusion 23a becomes a leg portion.

On the back surface of the first plate-shaped body 2, protrusions having the same protrusion length are appropriately formed in the circumferential direction in addition to the first corner protrusions 23a formed at four locations. That is, in the longitudinal direction continuous with one side of the first corner projection 23a, there are two I-shaped projections 23e and 23e in the plan view, four locations on both sides, and a T-shape in the plan view in the lateral direction and the longitudinal direction. Shaped protrusions 23d and 23d are formed at two locations on each side, and protrusions 23c and 23c having an L-shaped plan view are formed at two locations and four locations on both sides in the vicinity of both ends in the longitudinal direction. These form a group of legs when the first plate-shaped body 2 is turned upside down and used, and can be stably placed on an installation surface such as a floor. Further, when a plurality of first plate-shaped bodies 2 are stacked and stored, these leg groups 23a to 23e are fitted into the corresponding locking hole groups 29a to 29e of the other first plate-shaped body 2. Therefore, both are strongly stacked.

Next, the surface of the first plate-shaped body 2 will be described with reference to FIGS. 3 and 5. The surface 21c of the first plate-shaped body 2 is formed at four corners inside a predetermined dimension (t ₂ ) from a third peripheral groove 26 extending along the first side plate 21 and an inner wall 261 forming the third peripheral groove 26. It has a corner protrusion 27 extending upwardly. The “four corners” mean four corners of a virtual square inner wall formed inside a predetermined dimension (t ₂ ) from the inner wall forming the third peripheral groove 26. The corner protrusion 27 of this example is a square protrusion forming a grid pattern, and the outer corner thereof is partially cut off. Further, the surface 21c of the first plate-shaped body 2 has a first locking hole 29a into which the first corner protrusion 23a is fitted and a locking hole group 29b to 29e into which the leg groups 23b to 23e of the other plate-shaped body are fitted. .. The third peripheral groove 26 is a groove having a quadrangular view extending along the first side plate 21 and is open upward, and is located on the opposite side of the first peripheral groove 22 in the vertical direction in this example (FIG. 12). reference). Therefore, the groove width of the third peripheral groove 26 is substantially the same as the thickness (t ₁ ) of the first frame side plate 1, and is usually about 3 to 10 mm. The plan view of the first plate-shaped body 2 is a quadrangle (rectangle), and therefore, the plan view shape of the third peripheral groove 26 is also a quadrangle (rectangle) in a plan view corresponding to the shape of the first plate-shaped body 2. be. The surface 21c of the first plate-shaped body 2 has a grid groove 28 and a grid protrusion formed by the groove. As a result, various display aids using the grid can be attached.

The first locking hole 29a and the locking hole groups 29b to 29e have a side wall and a bottom wall forming the hole. Therefore, the first corner protrusions 23a and the leg groups 23b to 23e appearing on the back surface of the first plate-shaped body 2 are installed upright from the bottom wall downward. Therefore, when two first plate-shaped bodies 2 having the same shape are stacked and integrated, the first corner protrusion 23a and the leg groups 23b to 23e are each the first locking hole of the other first plate-shaped body 2. It will fit into 29a and the locking hole groups 29b to 29e.

Next, the second plate-shaped body 3 will be described. In the stage box 10 of this example, the second plate-shaped body 3 is the same as the first plate-shaped body 2, and the first plate-shaped body 2 is used upside down. Therefore, the description thereof will be omitted.

In the present invention, the second plate-shaped body 3 does not have to be the same as the first plate-shaped body 2. In that case, the second plate-shaped body 3 has a bottom plate portion and four second side plates, and the upper surface of the second plate-shaped body is an upper surface of the first frame side plate that is open upward and extends along the second side plate. A second peripheral groove having a groove width (t ₁ ) into which the lower end is fitted, and a second corner protrusion formed at the four corners inside a predetermined dimension (t ₂ ) from the inner wall forming the second peripheral groove. Can be used. In this case, the bottom plate portion is the same as the top plate portion 11 of the first plate-like body 2, and the four second side plates are the same as the four first side plates 12 (12a to 12d). Further, the second peripheral groove 32 is the same as the first peripheral groove 22 of the first plate-shaped body 2, and the second corner protrusion 33a is the same as the first corner protrusion 23a of the first plate-shaped body 2. The back surface of the second plate-shaped body 3 is the same as the front surface of the first plate-shaped body 2, and the description thereof will be omitted.

In the stage box 10, the first frame side plate 1 is an enclosure having a quadrangular plan view formed by four first large side plates 1a, 1a, 1b, and 1b having a predetermined thickness (t ₁ ). The inner dimension of the first frame side plate 1 is substantially the same as the outer dimension of the temporary surrounding wall formed by the first corner protrusion 23a of the first plate-shaped body 2. The thickness of the first frame side plate 1 is (t ₂ ) or more, ((t ₁ ) + (t ₂ ) + thickness of both walls forming the first peripheral groove 13) (reference numeral w) or less, and is usually 8 It is ~ 20 mm. By setting the thickness of the first frame side plate 1 to (t ₂ ) or more, at least the lower end surface or the upper end surface of the first frame side plate 1 is the end surface of the inner wall forming the first peripheral groove 22 or the second peripheral groove 32. It can come into contact with 222 and 323, and the installation is stable. Further, by setting the upper limit value of the thickness of the first frame side plate 1 to the above w, it is possible to prevent protrusion from the first plate-shaped body 2 and the second plate-shaped body 3. The thickness of the second frame side plate 3a is large, and a panel having a hollow inside, corrugated cardboard, or the like can also be used.

Next, an assembly method and a usage method of the stage box 10 will be described. Three members, a first plate-shaped body 2, a first frame side plate 1, and a second plate-shaped body 3, are prepared. Since the first plate-shaped body 2 and the second plate-shaped body 3 are the same, the number of parts is two. The second plate-shaped body 3 to be the bottom plate is placed on an installation surface such as a floor with the surface on which the second corner protrusion 33a and the leg group appear as the upper surface. Next, the lower end surface of the first frame side plate 1 is placed on the outer band-shaped portion w of the second corner protrusion 33a of the second plate-shaped body 3 and is erected. Next, the first plate-shaped body 2 to be the top plate is positioned above the first frame side plate 1 with the surface on which the first corner protrusions 23a and the leg groups 23b to 23e appear as the lower surface, and the first plate-shaped body 2 is positioned. The first corner protrusion 23a of the above is placed so as to be inside the first frame side plate 1 to form a stacking body. That is, the lower end surface of the first frame side plate 1 abuts on the upper surface 323 of the inner wall of the second peripheral groove 32 of the second plate-shaped body 3, and the upper end surface of the first frame side plate 1 is the first plate-shaped body 2. It is in contact with the lower surface 222 of the inner wall of the peripheral groove 22. As a result, the stage box 10 is obtained. In the stage box 10, the first frame side plate 1 is a thick plate-like body, and the weight of the entire box is heavy. Further, although the three members are stacked bodies, there is no deviation in the left-right direction, and the stability after assembly is high. The stage box 10 can be used alone or in combination of a plurality of stage boxes 10 to form a display stand set having various display surface shapes.

To disassemble the stage box 10, disassemble it into three members by the reverse method of the assembly method. The disassembled stage box 10 stacks the first plate-shaped body 2 and the second plate-shaped body 3, and the first corner protrusion 23a and the leg groups 23b to 23e have the first locking hole 29a and the locking hole group, respectively. When fitted into 29b to 29e, a low-height stage box in which two first plate-shaped bodies 2 having the same shape are stacked and integrated can be obtained. Further, by combining this with a single stage box, a plurality of stage boxes, or an assembled stage box 10, it is possible to form a display stand set having various display surface shapes. In addition, since the stacking height is low, it is also suitable for storage as it is.

Further, the back surface of the first plate-shaped body 2a has a quadrangular inner wall 231 (331) continuous with four corner protrusions 23a, and a plan view can be seen at an appropriate position of the inner wall 231 (331). An I-shaped protrusion 23b (33b) is formed. The height of the protrusions 23b (33b) is the same as the height of the corner protrusions 23a.

The surface of the first plate-shaped body 2a is a substantially flat surface except for the outer edge portion, and the peripheral groove 29a extending along the first side plate 21 (21c, 21c, 21d, 21d) and the corner protrusion 23a are fitted. It has a locking hole 29b. Further, it has a locking hole group 29c into which the leg group 33b of another plate-shaped body is fitted. The first peripheral groove 22a on the back surface of the first plate-shaped body 2a is a groove having a quadrangular plan view extending downward along the first side plate 21. Therefore, the groove width of the first peripheral groove 22a is substantially the same as the thickness (t ₁ ) of the first frame side plate 1A, and is usually about 3 to 10 mm. The plan view of the first plate-shaped body 2a is a quadrangle (rectangle), and therefore, the plan view shape of the first peripheral groove 22a is also a quadrangle (rectangle) in the plan view corresponding to the shape of the first plate-shaped body 2a. be.

The method of assembling the laminated stage box 10c is the same as that of the laminated stage box 10, and the description thereof will be omitted. Further, in the stage box 10c, although the first plate-shaped body 2a is not used upside down, it has the same effect as the stage box 10.

In addition to FIGS. 17 and 18, the stage box 10c may be used as shown in FIG. In the stage box 10d of FIG. 19, the same components as those of the stage box 10c of FIG. 18 are designated by the same reference numerals, the description thereof will be omitted, and the differences will be mainly described. That is, the difference between the stage box 10d of FIG. 19 and the stage box 10c of FIG. 18 is the shape of the frame side plate. That is, the stage box 10d in FIG. 19 uses a thin second frame side plate 1A, and the upper end portion of the second frame side plate 1A is fitted into the first peripheral groove 22a of the first plate-shaped body 2a. The lower end portion of the 2 frame side plate 1A is fitted into the peripheral groove 32a of the second plate-shaped body 3a. Thereby, a fitting type stage box 10d can be obtained.

Further, in the present invention, a stage box set (display stand set) can be formed by using a plurality of stage boxes 10 to 10d, respectively, or by using them in combination. For example, when two stage boxes 10 are stacked and used, the first frame side plate 1 may be assembled to the lower stage box 10. As a result, the number of the first plate-shaped body can be reduced by one. This usage can be applied to the stage boxes 10a to 10c except for the stage box 10d.

The first frame side plate 1 of the stage boxes 10 to 10d is not limited to the one having the above-mentioned thickness, and may have a thickness such that the tip thereof touches the inner wall forming the first peripheral groove 22. Therefore, there is more room for selection of the first frame side plate 1 to be used.

According to the present invention, two types, a lightweight fitting type and a heavy laminated type, can be obtained by changing the frame side plate. Therefore, at least two different types of stage boxes can be formed with a small number of parts, the cost can be suppressed, and the display effect can be enhanced.
