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 the protrusion of one block is inserted into the insertion opening of another block to connect many blocks. This allows it to 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.
The inventor of the present invention has solved these problems and created a block toy that has a geometrically beautiful overall shape when assembled, and has a cross-sectional inner and outer shape in which the upper half is a regular octagon and the lower half is a square. 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, have their side walls joined together, and a cylindrical portion is provided on the upper surface of each hollow hexagonal column. 1
block, and a second block with an L-shaped side surface in which another hollow hexagonal column is joined to the back wall of each hollow hexagonal column of this first block.
We have devised a block with the following blocks and have already filed applications (Utility Model Application No. 51121/1983, Japanese Unexamined Utility Model Publication No. 152699/1983).

This invention is a further development of the block toy related to the above-mentioned earlier application, and the bottom wall of a hollow composite octagonal prism, which is made by arranging and bonding hollow octagonal prisms with regular octagonal cross-sectional inner and outer shapes in a lattice pattern, has a predetermined width. A hollow polygonal pillar having at least all the outer walls and all the joint walls among the side walls of the hollow composite polygonal pillar with a planar wall is provided, and on the upper surface of each hollow unit polygonal pillar of the hollow polygonal pillar. A first block having a cylindrical portion integrally protruding thereon and a plurality of hollow hexagonal columns having a cylindrical portion integrally protruding from the upper surface are joined and integrated, and the above-mentioned is attached to the back wall of each hollow hexagonal column. By joining and integrating the hollow octagonal pillars and providing a second block with the top wall or bottom wall of the integrated hollow composite octagonal pillar as a flat wall of a predetermined width, the overall structure at the time of assembly is improved. The object of the present invention is to provide a block toy whose outer surface is composed of a wide continuous plane and many continuous regular octagonal prism outer surfaces and has a very beautiful appearance.

Next, the effects will be explained.

In order to assemble an animal model as shown in FIGS. 11 and 12 using this block toy, first, attach a hollow unit polygonal prism 5 of a 6×5 type first block 12-1 to another 6×5 type first block 12-1. The cylindrical portion 2 of the first block 12-2 is shifted by one in the lateral direction in FIG. 11, and each planar wall 13a is fitted toward the right side in FIG. A body portion 20 is formed.

Next, the cylindrical portion 2 of the 2×2 type first block 6-1 is attached to the lower surface of the hollow unit polygonal column 5 at the four corners of this body portion 20, and the planar wall 7a of the block 6-1 is placed on the right side in the figure. 2x2 type first blocks 6-2, 6-3, and 6-4 are sequentially attached below the block 6-1 to form the leg portion 2.
form 1.

In this case, two 2×1 type first blocks 3 may be used instead of one 2×2 type first block 6.

Furthermore, among the six cylindrical parts 2 arranged in three horizontal rows and two vertical rows at the center of the front end of the body part 20, two hollow-shaped units on the rear side of the 3×1 type first block 8-1 are attached to the two cylindrical parts 2 at the left end in the figure. The polygonal pillars 5 are fitted with the planar wall 9a of the block 8-1 facing right in the figure, and the remaining four cylindrical parts 2 are fitted with four hollow holes on the rear side of the 3×2 type first block 10-1. Similarly, the shaped unit polygonal column 5 is fitted with the planar wall 11a of the block 10-1 facing rightward.

and the 3×1 type and 3×2 type first block 8-1,
Hollow unit polygonal columns 5 of 2×1 type and 2×2 type first blocks 3-1, 6-5 are attached to the two rear and four rear column portions 2 of 10-1 in the Joki block 8-1. , 10-1 in the same direction, and these blocks 8-1, 10-1, 3

Further, the hollow hexagonal column 15 of the 1-type L-shaped block 14-1 is fitted into the cylindrical portion 2 at the center of the rear end of the body portion 20.
The cylindrical part 2 of the other 1-type L-shaped block 14-2 is inserted into the other hollow hexagonal column 15 of the block 14-1, and the 1-type 3rd column part 2 is inserted into the hollow hexagonal column 15 of the block 14-2. Insert block 18-1 of these blocks 14-1.14
Create a tail 23 by -2, 18-1.

Finally, hollow unit polygonal columns 5 of the 2×1 type first blocks 3-2, 3-3 are attached to each of the two cylindrical portions 2 of the body portion 20 on both sides of the 1 type L-shaped block 14-1. are fitted with the planar walls 4a of the blocks 3-2 and 3-3 facing forward to connect the blocks.

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
and a third by combining various blocks.
It can be assembled into any shape, such as the shape of an animal as shown in Figures 1 and 12.
By using a large-scale block such as the 5-type first block 12, even a large structure can be easily assembled.

Further, 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 7a of the 2×2 type first block 6 of the leg portion 21 are continuous, and the head portion 22
The planar wall 7a of the 2×2 type first block 6 and the planar wall 11a of the 3×2 type first block 10 are continuous, and a wide flat surface is formed on the right side of the model, and the front side and The left and rear surfaces are continuous outer surfaces of a regular octagonal prism.

In this way, the overall shape when assembled is geometrically very beautiful, including a wide plane and the outer surfaces of many regular octagonal prisms.Moreover, the continuous ridge lines of the regular octagonal prisms create a solid, sharp, or masculine shape. As a result, it can strongly attract children's interest, and it 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 internal cross-sectional shape is hexagonal, heptagonal, or regular octagonal to the columnar part 2. The inner surface of the 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 N to U
This means that even if the columnar part 2 is formed with highly accurate dimensions, it can be easily inserted and removed, and it is less likely to wear out even after long-term use, and a strong fitted state can be maintained for a long time.

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 hook-shaped members each having a square lower half are joined to form a B-shaped block body, and a cylindrical portion is placed on the top surface of each semi-circular shaped member. There is something protruding.

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, which 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, the block toy of this example still requires a large amount of force to insert and remove and is prone to wear, and the outer wall of the insertion port is difficult to deform due to its structure, so it cannot absorb dimensional errors to a great extent. 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 octagonal prism whose bottom wall was a flat wall. It is sufficient that the side surface is flat, the other three 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, it may be formed using a hollow polygonal column 24 having at least all the outer walls 24a and all the joint walls 24b among the side walls of a hollow composite polygonal column as shown in FIG. You can get the effect of
Moreover, when one end of the joining wall 24b is a free end, insertion and removal can be made easier.

Further, in the above embodiment, the bottom wall of the hollow composite octagonal prism was made into a planar wall when forming the second block of type 2, but the top wall may be made into a planar wall.

Further, in the above embodiment, the first block is a 2×1 type, 2
We have explained blocks with x2 type, 3x1 type, 3x2 type, and 6x5 type blocks, but this generally includes i hollow octagonal prisms in the horizontal direction (i is an integer of 2 or more). , the vertical direction is j
(j is an integer greater than or equal to 1) hollow composite octagonal prisms arranged in a lattice and joined together; Any number of i×j type first blocks can be provided, each of which closes off the entire upper surface of the space surrounded by the four hollow unit polygonal columns, and has a cylindrical portion protruding from the upper surface of each hollow unit polygonal column, For example, it may include a plurality of blocks of one type, for example, a 2×1 type.

In addition, in the above embodiment, the second block was described as having only a type 2 block, but this generally consists of k hollow hexagonal columns (k is an integer of 2 or more), and the upper surface of each hollow hexagonal column. At the same time, a hollow octagonal pillar is joined to the back wall of each hollow hexagonal pillar to integrate it, and the top wall or bottom wall of this hollow composite octagonal pillar has a width (k-
An arbitrary number of k-type second blocks each having a planar wall of 2+√2)l can be provided.

In addition, the width of the planar wall of the type 1 L-shaped block is (k-2+
√2) Since it does not satisfy the condition that Although the description has been made regarding the case where the device is provided, it is also possible to do so without it.

As described above, according to the present invention, hollow composite octagonal pillars having regular octagonal cross-sectional shapes are arranged in a lattice pattern and joined together, and the bottom wall of the hollow composite octagonal pillar is a planar wall of a predetermined width. A hollow polygonal pillar having at least all the outer walls and all the joint walls among the side walls of the polygonal pillar is provided, and the upper surface of the space surrounded by the four hollow unit polygonal pillars of the hollow polygonal pillar is completely closed off. A first block having a cylindrical portion integrally protruding from the upper surface of each hollow unit polygonal column, and a plurality of hollow hexagonal columns having cylindrical portions integrally protruding from the upper surface thereof are integrated by joining their side walls. , a second hollow octagonal column is joined and integrated with the back wall of each hollow hexagonal column, and the top wall or bottom wall of the integrated hollow composite octagonal column is a planar wall of a predetermined width; By configuring a block toy with blocks, it is possible to easily insert and remove them, and to obtain a strong mating condition.Moreover, when assembled, the appearance appears to be a wide continuous plane and many continuous outer surfaces of regular octagonal prisms, This has the effect of creating a very geometrically beautiful shape.
