Note that, in order to avoid complicating the drawings, in FIGS. 9 to 15, reference numerals that do not need to be particularly described are omitted from FIGS.

First, as shown in FIGS. 1 to 8,
The panel 1 according to the present invention is provided on each of the main body 2 and both ends of the main body 2 so that the panels 1 having the same shape can be bonded in three directions without using a special bonding member other than the panel 1. It has a schematic configuration having parts 10 and 20.

Here, for convenience of explanation, the main body 2 is made up of a surface (front surface) 4, a surface (back surface) 5, a surface (an end surface intersecting the end surface on which the convex portion is formed) 6, and a surface (an end surface on which the convex portion is formed). It is assumed that the shape is a rectangular parallelepiped shape composed of an end face 7 intersecting with an end face 7, an end face 8, and a face (end face) 9, and directions A (end face side), B direction (end face side), C direction (back face side), The joint 10 will be described using the direction D (front side). Joint 10 is a surface (surface)
A concave portion (surface-side concave portion) 1 formed on the side 4 and opening in the D direction side
1, a convex portion 12 formed on the surface 9 side of the concave portion 11 and protruding in the A direction side, a concave portion (end surface side concave portion) 13 formed on the end surface 9 and opening in the A direction side, and a convex portion 12 on the C direction side of the concave portion 13. A convex portion (convex portion) 14 formed adjacent to and protruding in the A direction side, a concave portion (rear surface side concave portion) 16 formed on the surface (back surface) 5 and opening in the C direction side, and a concave portion 16 on the A direction side And a convex portion 15 formed adjacent to and protruding in the C direction. These concave portions 11, convex portions 12, concave portions 13, convex portions 14, convex portions 15, and concave portions 16 are formed from the surface 6 side to the surface 7 side, respectively.

The convex portions 14 can be fitted into the concave portions 11, 13 and 16, respectively. As a basic connection between the panels 1, the convex portions 14 of one panel 1
The panels 1 and 1 can be joined in any one of three directions by fitting into each of the concave portions 11, 13 and 16. Specifically, when the projection 14 of one panel 1 is fitted into the depression 11 or the depression 16 of another panel 1, these panels 1
1 are orthogonal to each other (the panels 1 and 1 form an L-shape),
When the convex portion 14 of one panel 1 is fitted into the concave portion 13 of another panel 1, these panels 1 and 1 are included in the same plane (the panels 1 and 1 form a linear shape).

The convex portion 14 has the same width from the base end portion to the upper end portion, and each of the concave portions 11, 13, and 16 has a shape whose width does not change in the depth direction. The recesses 11, 13, and 16 can be fitted by approaching each other so as to abut each other. As another method for fitting the convex portion 14 and the concave portions 11, 13, 16, an open end formed by opening the concave surface 11, 13, 16 to the end surface 6 side or an open end formed by opening to the end surface 7 side is formed. From the open end, there is a method of inserting the convex portion 14 from the end.

Further, for example, the depth and width of the concave portion 11, the concave portion 13, and the concave portion 16 are each 1 / th of the thickness T of the panel 1.
The height and the width of the projections 12, 14, and 15 are each set to 1/4 of the thickness T. Therefore, the convex portion 14 and the concave portion 13 are formed on both sides of the longitudinal center line of the end face 9, and the distance from this central line to the convex portion 14 is made equal to the distance from the center line to the concave portion 13. (In this case, 0). Also,
While the end face of the main body 2, that is, the face 9 is divided into four equal parts in the width direction,
The concave portion 13 is formed in the second portion counted from one side, and the convex portion 14 is formed in the third portion. Therefore, the distances l ₁ = l ₂ shown in FIGS. 5 and 6 are satisfied. Also,
Since the height and the width of the convex portion 15 are each 1/4 of T, the distance from the concave portion 16 to the end surface 9 is equal to the distance from the back surface 5 to the convex portion 14. Further, for example, l ₁ = l ₃ (see FIG. 4). That is, the distance from the concave portion 11 to the end surface 9 is equal to the distance from the surface 4 to the convex portion 14,
The distance from the end face 9 to the recess 11 is set to １ ／ of the width of the end face.

The panel 1 is symmetrical with respect to the center line 3 of the main body 2 and has a concave portion (a concave portion on the back side) of the joint portion 20.
21, a convex portion 22, a concave portion (a concave portion on an end surface) 23, a convex portion (a convex portion) 24, a convex portion 25, and a concave portion (a concave portion on the front surface) 26 are a concave portion 11, a convex portion 12, a concave portion 13, and a convex portion of the joint portion 10, respectively. Part 1
4, the same shape and dimensions as the convex portion 15 and the concave portion 16. Therefore, the distance from the end face 8 to the recess 26 is set to １ ／ of the width of the end face 8, and the distance from the end face 8 to the recess 21 is set to の of the width of the end face 8.

The joining method of the panel 1 having such a configuration will be described below. First, in order to join the two panels 1 and 1 in a linear shape, as shown in FIG. 9 (A), the convex portions 14 or 24 are fitted into the concave portions 13 or 23. The method, as shown in FIG. 9 (B), replaces the respective convex portions 15 or the convex portions 25 with the respective concave portions 16 or the concave portions 26.
As shown in FIG. 9C, the protrusions 12 or the protrusions 22 are connected to the recesses 13 or the recesses 2 of each other.
There are three ways of fitting into three.

Here, since the length l ₁ of the panel 1 shown in FIGS. 5 and 6 is l ₁ = l ₂ , especially in the case shown in FIG. 4) and the back surface (surface 5) or front surface (surface 4) of another panel 1 are flush with each other, and the back surface (surface 5) of one panel 1 and another panel 1
The surface (surface 4) or the back surface (surface 5) is flush with each other, and these panels 1 and 1 can be joined with good appearance.

In order to join the two panels 1 and 1 into an L-shape, as shown in FIGS. 10A and 10B, the convex portion 14 or the convex portion 24 of one panel 1 is connected to the other panel. The method of fitting into the recess 11 or the recess 21 of the first surface 4 and the surface 5 (the surface 6)
And the side 7) with two sides. As shown in FIGS. 10C and 10D, the method of fitting the convex portion 14 or the convex portion 24 of one panel 1 into the concave portion 16 or the concave portion 26 of the other panel 1 is performed by using the surface 4 and the surface 4. 5 (surface 6 and surface 7) are two sides.

Here, since l ₁ = l ₃ , FIG.
0 (B), the back surface (surface 5) or front surface (surface 4) of one panel 1 and the end surface (surface 9) of the other panel 1 are shown.
Or, since the surface 8) is flush, the panels 1 and 1 can be joined with good appearance.

Also, since the width and height of the projections 15 (projections 25) are equal, especially in the case shown in FIG. 10C, the surface (surface 4) or the back surface (surface 4) of one panel 1 is provided. 5) and the end surface (surface 9 or surface 8) of the other panel 1 are flush with each other, so that these panels 1 and 1 can be joined with good appearance.

The panel 1 can be joined by three basic joining methods including the above-mentioned three joining methods of the linear shape and four joining methods of the L-shape, and a total of seven basic joining methods. There is a joining method of a combination of methods (some combinations are not possible). More exceptionally, when the two panels are joined by the method shown in FIG. 10D, the projection 14 or 24 of one panel 1 and the projection 1 of the other panel are joined.
The method of fitting the convex portion 14 or the convex portion 24 of another panel 1 into the concave portion 30 formed between the panel 2 and the convex portion 22 is performed by changing the surfaces 4 and 5 (the surfaces 6 and 7) of the panel 1 2 on the front and back
(Not shown).

For example, as a typical example of a method of joining three panels in a T-shape, two panels 1, 1 joined in a linear shape as shown in FIG. As shown in FIG. Of these, FIG. 11A is a combination of FIG. 9A and FIG. 10A. FIG. 11B is a combination of FIG. 9A and FIG. 10B.
(C) of FIG. 11 is a combination of (A) of FIG. 9 and (D) of FIG. 11 (D) is the same as FIG. 9 (A) and FIG.
0 is a combination with (C).

If the panel is rotated by 180 degrees, the connection is the same as one of the drawings in FIG. 11, but if the orientation of the panels is not changed, another panel is joined to the right side of the two panels 1, 1 joined in a linear shape. There are four methods for joining the panels 1 as shown in FIGS. FIG. 12A is a combination of FIG. 9A and FIG. 10C. (B) of FIG. 12 is a combination of (A) of FIG. 9 and (D) of FIG. FIG. 12C is a combination of FIG. 9A and FIG. 10B. FIG.
(D) is a combination of (A) in FIG. 9 and (A) in FIG.

Further, as a method of joining the four panels in a cross shape, for example, the cases shown in FIGS. FIG. 13 shows a combination of FIG. 11D and FIG. 12A. FIG. 14 shows a combination of (A) of FIG. 11 and (B) of FIG. FIG. 15 shows a combination of (D) of FIG. 11 and (C) of FIG.

In addition, although illustration and detailed description are omitted, a plurality of panels 1 are joined to each other to form a combination of a straight shape and a straight shape, a straight shape and an L-shape. Combination of shapes (T-shape, cross shape, etc.), L-shape and L-shape combined shapes, etc. to form a linear, L-shaped, T-shaped panel composite , A cross-shaped panel, and a combination of these panels can be realized.

By joining such panels 1 by the above-mentioned joining method and by constituting the above-mentioned joining structure with these panels 1, the panel 1 can be made of, for example, a partition panel, a wall panel, a floor panel, a ceiling panel or the like. It can be used as an architectural use, a model, an educational toy to be assembled and played, and the like. Further, the present invention can be widely applied to other applications in which panels need to be joined to each other. In particular,
Since the panel 1 is characterized in that the panels 1 can be joined to each other in three directions, the panel 1 can be suitably used for applications in which a structure in which surfaces intersect with each other by a plurality of panels 1 needs to be configured. Thus, for example, a plurality of panels 1 joined together can form a part of a building that covers a plurality of surfaces, such as a partition and a wall, a wall and a floor, a wall and a ceiling, a partition and a floor, and a partition and a ceiling. It is possible. As another example, for example, a plurality of panels 1 horizontally joined to serve as a floor on a floor with a building and a ceiling on a floor below the building,
It is also possible to form a partition or wall of the certain floor and a partition or wall of the floor below the certain floor continuously with the plurality of panels 1. Here, a fixing means such as an adhesive may be used for the joint surfaces between the panels 1 in some cases.

Further, by appropriately selecting the above-described various joining methods and configuring various joining structures, the shape and dimensions of the structure constituted by the plurality of panels 1 can be adjusted. The dimensions of the partitioned space can also be adjusted. Therefore, for example, when the panel 1 is used as a partition, it is possible to appropriately adjust the size of the space partitioned by the partition. Specifically, for example, there are three types shown in FIGS. 9A to 9C even in the case of straight-shaped joining, and in the case of L-shaped joining, there are three types shown in FIGS. 10A to 10D. There are four types shown. Since the positional relationships between the joined panels 1 are all different depending on the respective joining methods, it is possible to appropriately adjust the size of the space partitioned by the partition.

Next, an example in which the present invention is applied to a partition structure as a joining structure of the panel 1 according to the present invention will be described with reference to FIG. As shown in FIG. 16, a desired partitioning structure (panel joining structure) 50 is constituted by a plurality of panels 1,... By appropriately combining a straight joining method and an L-shaped joining method. The interior of the space 40 can be partitioned by a desired partitioning method.

Also, when the panel 1 is used as a part of a model, or used as an educational toy or the like to be assembled and played, various joining structures can be realized by the above-described various joining methods.
