Description

[Detailed description of the invention] This invention relates to block toys.

In general, block toys are made up of multiple blocks each having a protrusion and an insertion opening, and by inserting the protrusion of one block into the insertion opening of another block and pouring out many blocks. It can be assembled into any shape, such as an airplane, ship, or automobile.

However, with conventional block toys, it is difficult to assemble into a compact rectangular parallelepiped shape with a small number of blocks.
There was also the problem that appropriate fitting strength could not be obtained.

A plurality of hollow hexagonal columns having a hexagonal shape and a height equal to the length of one side of the square, which is the lower half of the square, are joined at their side walls, and a cylindrical portion is provided protruding from the upper surface of each hollow hexagonal column. A block including a first block and a second block having an L-shaped side surface in which other hollow hexagonal columns are joined to the back wall of each hollow hexagonal column of the first block has been devised, and an application has already been filed. (Utility Application No. 55-51121, Utility Model Application No. 56-152699).

This invention is a further development of the block toy according to the above-mentioned prior application, and includes a hollow composite octagonal prism with an upper side wall and a right or A hollow polygonal pillar is formed which has at least all the outer walls and all the joint walls among the side walls of the hollow composite polygonal pillar, each of which has a left side wall as a planar wall of a predetermined width, and A first block that completely closes the upper surface of a space surrounded by two hollow unit polygonal columns and has a cylindrical portion integrally protruding from the upper surface of each hollow unit polygonal column, and a side wall thereof having a plurality of hollow hexagonal columns. At the same time, a cylindrical part is protruded from the upper surface of each hollow hexagonal column, and the hollow octagonal column is joined and integrated to the back wall of each hollow hexagonal column. By providing a second block in which the top wall or bottom wall of the formed hollow composite octagonal prism is a flat wall of a predetermined width, the outer surface of the overall shape when assembled is a wide flat surface and the outer surface of many regular octagonal prisms. The purpose is to provide a block toy with a very beautiful appearance.

Next, the effects will be explained.

To assemble an animal model using this block toy,
First, the hollow unit polygonal column 5 of the 6 x 5 type first block 12-1 is shifted by one column part 2 of the other 6 x 5 type first block 12-2 in the lateral direction of Fig. 11, and each plane shaped wall 13
a toward the right side in FIG. 12 and the planar wall 13b (not visible in the figure) toward the rear, and both blocks 12-1,
12-2 forms the body portion 20.

Next, the cylindrical portion 2 of the 2×2 type first block 8-1 is attached to the hollow unit polygonal column 5 at the four corners of the lower surface of the body portion 20, and the planar wall 8a of the block 8-1 is placed on the right side in the figure. Then, the planar wall 9b (not visible in the figure) is fitted toward the rear, and the 2×2 type first block 8 is fitted in the same way below the block 8-1.
-2, 8-3, and 8-4 are sequentially connected to form the leg portion 21.

In this case, two 2×1 basic blocks 3 may be used instead of one 2×2 first block 8.

Next, 3 x 1 type basic blocks 6-1 are attached to the six cylindrical parts 2 in 3 horizontal rows and 2 vertical rows at the center of the front end of the body part 20 in each horizontal row.
, 6-2, 6-3, the two hollow unit polygonal columns 5 on the rear side are fitted with the planar walls 7a of the blocks 6-1, 6-2, 6-3 facing right in the figure. Blocks 6-1, 6-
Hollow unit polygonal columns 5 of 2×1 type basic blocks 3-1, 3-2, 3-3 are attached to the two rear cylindrical portions 2 of 2, 6-3, respectively. , 3-3 are fitted toward the right side in the drawing, and these blocks 6-1, 6-2, 6-3, 3-1, 3-2, and 3-3 form the head 22. form.

Then, the hollow hexagonal column 15 of the type 1 L-shaped block 14-1 is fitted into the columnar section 2 at the center of the rear end of the body section 20, and the other hollow hexagonal column 15 of the block 14-1 is fitted with another one. The cylindrical portion 2 of the L-shaped block 14-2 is connected to the block 14-2.
The cylindrical portion 2 of the type 1 third block 18-1 is inserted into the hollow hexagonal column 15 of the block 14-1, 14-2,
18-1 forms the tail 23.

The third block 18 is capable of closing the opening of the hollow polygonal column appearing on the outer surface of the model thus assembled.

Finally, 2×1 type basic blocks 3-4, 3-5 are attached to each two cylindrical portions 2 of the body portion 20 on both sides of the 1 type L-shaped block 14-1. The planar wall 4a (not visible in the figure) of 2 is fitted facing rearward.

In this way, animal models as shown in FIGS. 11 and 12 can be assembled.

In the block toy of this embodiment as described above, the first and second
By combining various blocks such as the third block and the third block, it is possible to assemble it into any shape such as the shape of an animal as shown in FIGS. 11 and 12.
By using a large block such as the ×5 type fourth block 12, even a large structure can be easily assembled.

Furthermore, in the above assembly example, the planar wall 13a of the 6×5 type first block 12 of the body portion 20 and the planar wall 9a of the 2×2 type first block 8 of the leg portion 21 are continuous, and the planar wall 9a of the 2×2 type first block 8 of the body portion 20 is continuous. 2×1
The planar wall 4a of the basic block 3, the planar wall 13b of the 6×5 first block 12, and the planar wall 9b of the 2×2 first block 8 of the leg portion 21 are continuous, and the head 22 2
The planar wall 4a of the ×1 type basic block 3 and the planar wall 7a of the 3×1 type basic block 6 are continuous.

Therefore, a wide plane is formed on the right side and the back surface in the drawing of the model of the above assembly example, and the outer surface of a regular octagonal prism is continuous on the left side surface and the front surface in the drawing.

In this way, the overall shape when assembled includes a wide plane and the outer surfaces of many regular octagonal prisms, making it very geometrically beautiful.Moreover, the continuous ridge lines of the regular octagonal prisms give it a solid, sharp, or masculine appearance. It gives a strong impression, can strongly attract children's interest, and can also cultivate children's aesthetic sense.

In addition, the blocks are connected by fitting the hollow hexagonal column 15 or the hollow unit polygonal column 5 whose cross section is hexagonal, heptagonal or regular octagonal to the columnar part 2.
The inner surface of the hollow hexagonal column 15 or the inner surface of the hollow unit polygonal column 5 and the outer surface of the columnar part 2 are defined by six points A to F, seven points G to M, or Contact occurs at 8 points from N to U, so even if the cylindrical part 2 is formed with high precision dimensions, it can be easily inserted and removed, and it does not wear out much even after long-term use, and maintains a strong mating state for a long time. can.

By the way, conventionally, as a block that can be easily inserted and removed, as shown in Japanese Utility Model Application Publication No. 48-80699 and Japanese Utility Model Application Publication No. 48-58895, the upper half of the block has a circular cross-sectional shape. At this point, the side walls of two hollow semi-cylindrical members each having a square lower half are joined to form a B-shaped block body, and a cylindrical part is protruded from the top surface of each semi-cylindrical member. There is something I did.

However, when the block described in the above publication is assembled, its appearance is a series of flat and curved surfaces, and while a series of curved surfaces gives a flexible, feminine impression, this A block with continuous ridge lines as in the embodiment gives a solid, sharp, and masculine impression, and the impression it gives is completely different from the conventional block described in the above-mentioned publication.

In addition, in the conventional block described in the above publication, in the fitted state, the semicylindrical insertion opening part and the cylindrical part contact at the entire upper semicircle and at one point below, and the contact area is large. However, in the block toy of this example, the block toy of this embodiment still requires a large force to be inserted and removed and is easily worn out, and furthermore, the outer wall of the insertion port is difficult to deform due to its structure, so it cannot absorb dimensional errors very much. As mentioned above, it can be easily inserted and removed, and is not prone to wear.Furthermore, since the insertion opening can be elastically deformed due to its structure, dimensional errors can be sufficiently absorbed.

In the above embodiment, the first block was formed using a hollow composite polygonal prism, but this is because when the block is viewed as a substantially quadrangular prism, two mutually perpendicular side surfaces are flat, and the other two sides are flat. Since it is sufficient that the two side surfaces are continuous with the outer surface of the regular octagonal prism, and the inner surface of each hollow unit polygonal prism of the block has a shape that can fit into the cylindrical part, for example, the first
It is sufficient to use a hollow polygonal column 24 having at least all the outer walls 24a and all the joint walls 24b among the side walls of the hollow composite polygonal column as shown in FIG. 3, and it is possible to obtain the same effect as in the above embodiment. Moreover, when one end of the joining wall 24b is a free end, insertion and removal can be made even easier.

In addition, in the above embodiment, the hollow composite polygonal prism of the first block is a hollow composite octagonal prism in which the upper side wall and the left side wall are planar walls. Alternatively, the right side wall may be a planar wall.

Further, in the above embodiment, when forming the second block, a hollow composite polygonal column with a planar upper wall was used, but a hollow composite polygonal column with a planar wall as the bottom wall may also be used.

Further, in the above embodiment, the first block is 2×2 type, 3
We have explained the case where blocks of ×2 type and 6 × 5 type are provided, but this has i hollow octagonal prisms in the horizontal direction (i is 2
(an integer greater than or equal to
−2+√2)l and the right or left side wall is (
j-2 + √2) l of an i x j type hollow composite polygonal column having a planar wall with an arbitrary number of i x j type first blocks each having a cylindrical part protruding from the upper surface of each hollow unit polygonal column. For example, it may include only a plurality of 2×2 type blocks.

In addition, for the 2×1 type basic block and 3×1 type basic block, the width of the planar wall of the right or left side wall is the above (j-2+
√2) Since they do not satisfy the condition 1, they do not belong to the first block, and the block toy of the present invention does not need to include them.

Furthermore, in the above embodiment, a case was explained in which only a type 2 second block was provided as the second block, but this is made by integrating k hollow hexagonal columns (k is an integer of 3 or more) by joining their side walls. , a cylindrical part is provided protrudingly on the upper surface of each hollow hexagonal column, and a hollow octagonal column is joined to the back wall of each hollow hexagonal column to integrate it, and the upper side of the hollow composite octagonal column formed by this integration. An arbitrary number of k-type second blocks whose walls or bottom walls are planar walls with a width (k-2+√2)l may be further provided.

In addition, the width of the planar wall of the type 1 L-shaped block is above (k
Since it does not satisfy the condition -2+√2)l, it does not belong to the second block, and the block toy of the present invention does not need to include it.

Further, in the above embodiment, the case where the third block is provided has been described, but it is not necessary to provide this third block.

As described above, according to the present invention, the upper wall and the right or left side wall of a hollow composite octagonal prism, which is formed by arranging and joining hollow octagonal prisms having regular octagonal cross-sectional shapes in a lattice pattern, are arranged in a plane with a predetermined width. A space formed by a hollow polygonal column having at least all outer walls and all joint walls among the side walls of a hollow composite polygonal column with shaped walls, and surrounded by four hollow unit polygonal columns of this hollow polygonal column. A plurality of first blocks whose upper surfaces are all closed and a cylindrical portion integrally protrudes from the upper surface of each hollow unit polygonal column, and a plurality of hollow hexagonal columns are integrated by joining their side walls, and the A cylindrical portion is provided protruding from the upper surface of each hollow hexagonal column, and the hollow octagonal column is joined to the back wall of each of the hollow hexagonal columns to be integrated, and the upper side of the hollow composite octagonal column formed by this integration. By configuring a block toy with a plurality of second blocks whose walls or bottom walls are planar walls of a predetermined width, it is possible to easily insert and remove them, obtain a strong mating state, and maintain the overall shape when assembled. It has a wide plane and many regular octagonal prisms on the outside, which has the effect of giving it a very beautiful geometric appearance.
