A joint 2D is formed in two directions with a width of 90° on the same plane, and one joint 2D is formed perpendicular to the plane. The joint 2E is formed in three directions on the same plane and one joint 2E is formed perpendicular to the plane, and in FIG. and 1 perpendicular to the plane
Further, in Fig. 1g, the rod connecting portions 1 are formed in four directions with a width of 90° on the same plane, and two joints 2F are formed perpendicularly to the front and back surfaces of the plane. The formed joint 2G is shown.

FIG. 2 shows the rod 3, which has a rectangular cross section and is hollow.
The length of the rods 3 is not specified, and when assembling the shelf, a long rod can be cut to any length, or one of a predetermined length can be selected.

Note that the rod 3 and the rod connecting portion 1 are connected in a static fit state.

3a to 3h each show various types of shelves made of decorative plywood, for example. Figure 3a shows a shelf board 5A in which a U-shaped notch 4 is provided at a fixed position from each corner on a pair of opposing sides of a rectangular plate, and Figure 3b shows a rectangular plate. A shelf board 5B is provided with a U-shaped notch 4 at a certain position from each corner of both ends of the board on one side of the board.
Fig. 3c shows a shelf board 5C in which a U-shaped notch 4 is provided at a certain position from the two corners of the ends in the same direction on a pair of opposing sides of a rectangular plate.

A shelf board 5E is shown in which a U-shaped notch 4 is provided at a certain position from the other corner opposite to the corner shown in FIG. 3d on one side of a rectangular plate.

Each of the notches 4 has the same shape, and the second notch 4 has the same shape.
In the cross section of the rod 3 shown in the figure, it has a shape corresponding to the outer contour of the half side thereof. That is, when the cross section of the rod 3 shown in FIG. 2 is a regular square with a length L, each cutout 4 is formed as a rectangular cutout with a depth of L/2 and a width L. Further, the distance l between each notch 4 and the corner portion in the vicinity thereof can be set arbitrarily.

In addition, each notch 4 and the L-shaped notch 7 described later also have the function and effect of preventing the shelf board from slipping against the shelf frame.

Furthermore, although FIGS. 3f to 3h show shelf boards that do not have the above-mentioned notches 4 at all, unlike the above-mentioned respective shelf boards 5A to 5E, there is a slip prevention part formed of a protrusion integrally formed on the back surface. has. That is, FIG. Shelf board 5F with anti-slip portion 6
In Fig. 3g, four anti-slip portions 6 are provided on the back surface of a rectangular plate at a distance of L+l from one side and at a distance of L/2 from the other three sides. The shelf board 5GE shown in FIG.

Here, all of the L-shaped notches 7 have the same size and shape, but each of the notches 7 has two sides with a length of L/2.

Note that each of the shelves 5A to 5H shown in FIGS. 3a to 5h and each of the shelves 8A to 8E shown in FIGS. 4a to 4e are of the same size. The size is not particularly limited, such as a shelf board that is doubled only in the direction, a shelf board that is doubled only in the lateral direction, etc.

Below, various joints 2A or 2 mentioned above
G, the basic configuration when assembling a shelf using the rod 3, various shelf boards 5A to 5H, and shelf boards 8A to 8H will be explained.

FIG. 5 shows an example in which a rod 3 having a predetermined length is assembled at right angles using a joint 2A. As mentioned above, the joint 2A is
It has two rod connecting parts 1 with a width of 90 degrees, and each of these rod connecting parts 1 is inserted into the hollow part of one end of the rod 3 using a wooden hammer into a joint 2A.
Insert with strong force, such as by tapping, to obtain a static mating connection.

In this way, at the other end of each of the rods 3, the joints shown in Figure 1 a to g are arbitrarily selected and connected to other rods, thereby constructing a shelf frame made of lattice-shaped rods. After that, a shelf board arbitrarily selected from among the shelf boards 5A to 5H and 8A to 8E is placed on a rod frame formed on one horizontal plane of this shelf frame.

In this case, as shown in FIG. 6a, the rod 3 constitutes a frame having a width three times that of the shelf board and a depth slightly shorter than the depth of the shelf board at the center line position of the rod 3, and Let us take as an example a shelf frame in which opposing sides are connected by another rod 3 at 1/3 of the point, and other rods are vertically arranged at each connection point of each rod. As is clear from the figure, from left to right, the above-mentioned shelf boards 5A, 5B,
It can be seen that 5B can be arranged respectively. In this case, the rod 3 on the width direction side of the shelf frame
The sides of each shelf board 5A, 5B, 5B have a length l.
It will be in a state where it stands out.

In addition, as shown in FIG. 6b, the rod 3
The frame has the same width as the shelf board at the center line position, and the depth is slightly shorter than the depth of two shelf boards, and the other rods are arranged vertically at each connection point of each rod. Take a shelf frame as an example.
In this case, at the same time as shown in FIG. 6a, in order to make the sides of the shelf protrude beyond the rods 3 on the widthwise sides of the shelf frame, the shelves 5C, 5C are selected.

Further, as shown in FIG. 6c, the frame has a width twice as wide as the shelf board and a depth slightly shorter than the depth of two shelf boards at the center line position of the rod 3, and each corner of the frame Take as an example a shelf frame in which each rod in a section has another rod arranged vertically at each connection point. In this case, as described above, in order to make the sides of the shelf protrude beyond the rods 3 on the widthwise sides of the shelf frame, as is clear from the figure, two shelf boards 5D and two shelf boards are required. 5E will be selected.

Furthermore, as shown in FIG. 6d, a shelf frame similar to that shown in FIG. 5a but without any other rods vertically disposed outside its corners is taken as an example. In this case, the shelves placed on both sides are shelf boards 5
B, shelf board 5F is selected as the shelf board arranged in the center. Here, as mentioned above, the shelf board 5F is provided with the slip-stopping part 6 on its back surface, and the slip-stopping part is shown in FIG. 7, which is a cross-sectional view taken along the line X-X in FIG. As you can see, it is positioned inside the rod frame.

Further, as shown in FIG. 8a, the rod 3 constitutes an outer frame having a depth slightly shorter than the depth of two shelf boards and a width three times that of the shelf board at the center line position of the rod 3, A shelf frame is taken as an example in which rods 3 are vertically arranged at each intersection point formed when the outer frame is divided into two equal parts in the depth direction and three equal parts in the width direction. In this case, as is clear from the figure, the shelf surface can be constructed by using six shelf boards 8A.

Fig. 8b shows an outer frame having a depth slightly shorter than the depth of two shelf boards and twice the width of the shelf board at the center line position of the rod 3, and a depth on both sides of the outer frame. Rod 3 at the position where the direction is divided into two
shows an example of a shelf frame with vertically arranged shelves. In this case, as is clear from the figure, the shelf surface can be constructed by using two shelf boards 8D and two shelf boards 8E.

Next, the case of actually configuring the shelves will be explained. It is assumed that the shelf frame shown in FIG. 9 is constructed using the rod 3 described above and joints appropriately selected from the joint group shown in FIG. 1.
The shelf frame shown in the figure consists of three shelves. first,
As is clear from FIG. 10, at the bottom of the shelf frame, the shelf board 5C is
Can be used in combination. In addition, since the second stage of the shelf frame can take the same form as shown in FIG. 6c, the first stage
As shown in FIG. 1, two shelf boards 5D and two shelf boards 5E can be used in combination. Furthermore, at the top of the shelf frame, a twelfth
As shown in the figure, three shelf boards 5C, shelf boards 5D, 5
E, 5G can be used in combination.

Further, FIG. 13 shows another example of a shelf frame, which has a three-tier shelf similar to the shelf frame shown in FIG. 9. Since the lowermost and second shelf surfaces have the same configurations as those shown in FIGS. 8a and 8b, respectively, the shelf boards shown in FIGS. 8a and 8b can be used. Also,
Since the top shelf has the same structure as the top shelf frame shown in FIG. 9, the shelf board shown in FIG. 12 can be used.

Although the shelf board material described above is an example in which the rods have a rectangular cross section, they may also have a circular cross section, and examples thereof will be described below.

In addition, each of the shelves shown in FIGS. 17a to 17e is different from the shelf shown in FIG. Plates 18A-18E are shown. Each of these shelf boards corresponds to the shelf board shown in FIG. 4 described above. However, unlike the shelf board shown in FIG. 4, a rod cover piece 15 is formed on each side close to the notch 12 among a pair of sides perpendicular to the side formed by the semicircular notch 12. At the same time, on the back of the shelf board, parallel to the rod cover piece 15, on a straight line imaginary passing through the center line of the circle assumed from the semicircular notch 12, and on the other three
