2. Description of the Related Art A large block for an assembly play toy is known in which a fitting groove is formed that is approximately equal to the thickness of the plate material. In this conventional example, parallel girders are assembled as shown in Fig. 5, and these are assembled into a warehouse structure, but the combinations are extremely poor and the users are not satisfied, and the warehouse building ability of the users is not satisfied. The educational effects of this increase cannot be expected.

This idea eliminates these inconveniences,
Next, the structure of one embodiment will be explained in detail. Main body P
is a blow-molded hollow panel made of plastic, the bottom is symmetrical with the plane, the left and right sides are the same shape, and its size is 130 cm in width and 30 cm in height.
cm, with a thickness of 5 cm. In this embodiment, as shown in FIGS. 1 to 3, elongated grooves 6, 6 are formed in the center of the main body P, square steel pipes 7 are dropped into each elongated groove 6, fixed with rivets, and square steel pipes are formed on both sides of the elongated groove 6. The through holes 8, 8' of the mold are formed, and the through holes 8, 8' are formed.
Deep groove-shaped reinforcing ribs 9, 9 with a dish-shaped cross section are formed on the outer side of 8', and these reinforcing ribs 9 are formed in pairs, upper and lower, and their bottom surfaces 9', 9' are in contact with each other, and both sides of the main body P A plurality of small grooves c and stepped grooves e, which will be described later, are formed at symmetrical positions on the edge, the four corners are formed into a large radius, and a string insertion hole 11 is bored in each corner 10 of the ear piece 12.
A shallow groove 13 is formed along the periphery of the main body P. The strength of this embodiment is extremely high due to the square steel pipe 7, the deep reinforcing ribs 9, the shallow grooves 13, and the elongated grooves 6.The original purpose of the shallow grooves 13 is to hold the hands, and the user can use the shallow grooves 13 with their fingers. can be inserted to facilitate the mating and unmating operation described below. In addition, the small claws 14, 1 provided in each small groove c and each stepped groove e
4, 14, . . . assist in preventing the block from coming off when it is fitted. In addition, as shown in the first figure, small grooves c are formed at positions 1 and 5 on the upper edge of the main body P and at positions 1, 2, 4, and 5 on the lower edge.
At positions 2, 3, and 4 on the upper edge and at position 3 on the lower edge, stepped grooves e consisting of small grooves c and large grooves d are formed. To explain, the center of the stepped groove e at positions 3 and 3 is at the center vertical line (imaginary line) a position, and the center of the stepped groove e and small groove c at positions 2, 2, 4, and 4 is at the center vertical line. The centers of the small grooves c at positions 1, 1, 5, and 5 are at the vertical line (imaginary line) a′, which is a distance L from the center vertical line a, and are located at the vertical line (imaginary line) a″, which is a distance n from the center vertical line a. position, furthermore, the vertical length of the main body P is W, the thickness is T, the width of the small groove c is t, the width of the large groove d is V, the small grooves c at positions 2 and 4 from the central vertical line a,
If the length to the center of the stepped groove e is L, the slight allowance for fitting is α, and the larger allowance is β, then w = 1/4W + α, t = T + α, l = L- β (β > α), U = 1/2W - α, V = 1/2W = U + α, m = 1/2T + α, and small grooves c at positions 1 and 5 from the center vertical line a. , c is the length from the inner side of the small groove c at the position 1 to the center horizontal line b
The length from the inner side of the small groove c at the position 5 of the upper through hole 8' to each outer side of the through hole 8 is set to √2n.

Next, some of the combination aspects of this example will be explained as follows.
This will be explained according to Figure 2. As shown in FIG. 5, if the small grooves c and c at positions 1 and 5 are used to fit together, and the four blocks are assembled in a grid, the internal space will be widened, and similarly as shown in FIG. , by using the small grooves c, c or stepped grooves e, e at the 4 positions, the internal space can be narrowed by assembling it in a cross-shaped structure, and by assembling it in the manner shown in Figures 5 and 6, it becomes a structure like a storage shed. . Also, since U=V-α from the above setting formula, this embodiment can be fitted horizontally as shown by arrow A in FIG. It can also be assembled. Further, as shown in Fig. 7, the parallel girder units A and B assembled using the small grooves c and c at positions 2 and 4 and the small grooves c and c at positions 1 and 5 are brought close together, and the units A and B Small grooves c and c at positions 2 and 4
By assembling and connecting small grooves c and c at positions 2 and 4 of blocks C and C of this embodiment, a large connected structure can be obtained. At this time, since the distance between the small grooves c and c at positions 2 and 4 is set to 2L, both units A and B are connected with an allowance of 2β left between them. Further, if stepped grooves e and e are used for connection at positions 2 and 4, since the stepped groove e has a large groove d, the blocks C can be connected horizontally in a flat plate form. Furthermore, as shown in FIG. 8, the small groove c at the 1 position or the small groove c at the 5 position of the two sheets of this embodiment is fitted together to form a roof, and this is attached to the wall C, which has the above-mentioned roof structure. You can build a house by placing it on it. At this time, if a known T-shaped block is inserted into the through holes 8, 8', the roof (R) will be locked to the wall (C). Since the length to each outer side of the holes 8 and 8' is set to √2n, assembly can be ensured as shown. Note that the through holes 8, 8' can be used not only for the purpose described above, but also by inserting, for example, a known axle block, a handle shaft block, etc. Further, as shown in FIG. 9, this embodiment can be installed obliquely in a flat plate shape by using the large groove d and the small grooves c, c at the 1, 1 or 5, 5 positions obliquely, as shown in FIG. 10. The string 15 may be passed through the string insertion hole 11 and fixed. Furthermore, since m=1/2T+α, it is also possible to fit the block C of another embodiment into the end space M of this embodiment which is arranged in a cross-section as shown in FIG. Therefore, by using a plurality of blocks of this embodiment, it is possible to assemble an extremely large number of things, and it is also possible to combine them with other known blocks, allowing children to enter, ride on, and move them. It is extremely effective as a basic structure for large blocks. Incidentally, according to this embodiment, by applying the above-mentioned combination mode, in addition to the bench with table shown in Fig. 12, a play house, a slide, a tricycle, an airplane, a young gym, a staircase, a jump stand, a stage, a seesaw, etc. can be created. It is something that can be assembled.

In this way, this invention has a plurality of stepped grooves consisting of a small groove and a large groove, and a plurality of small grooves, which are provided at symmetrical positions on both side edges of the main body, which is an elongated panel, and the width of the small groove is smaller than the thickness of the main body. Since the width of the large groove is set to be larger than the distance U between the grooves at the symmetrical position by the fitting allowance, it is possible to form internal spaces of various sizes, for example, as shown in FIGS. 5 to 7. Moreover, by assembling these, large and small rooms can be created, and the main body can not only be fitted vertically with the small groove, but also horizontally with the large groove, so that it can be used for stairs, etc. The combination of tables, benches, stages, seesaws, etc. can be expanded all at once, and it can also be installed diagonally in the form of a flat plate as shown in Figure 9 to form a slide, giving the user satisfaction. Of course, it also has great educational effects, such as increasing creativity.
