Description

[Detailed explanation of the idea] 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 together. This allows it to be assembled into any shape, such as an airplane, ship, or automobile.

By the way, when a child uses this block toy to assemble and play with models such as airplanes, the child's strength is not very strong, so the protruding part of the block and the insertion opening can be easily inserted and removed, and it also comes out easily during assembly. It is desirable that appropriate fitting strength be obtained to prevent the mating material from collapsing.

Therefore, a large number of mating structures have been devised in the past that allow block toys to be easily inserted and removed while providing appropriate mating strength, but this design was developed under these circumstances. The present invention provides a toy block that has an insertion opening with a completely new shape that has not been seen before, and that can be easily inserted and removed while providing appropriate fitting strength.

More specifically, the present invention is a hollow composite octagonal prism in which mXn (mtn is an integer of 2 or more) hollow octagonal prisms with regular octagonal cross-sectional shapes are arranged in a lattice pattern and their adjacent side walls are joined. The present invention is characterized in that by removing all the joint walls, a block having mXn insertion openings that can be fitted into the cylindrical portions of other blocks is formed.

An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show a first block constituting a block toy according to an embodiment of the present invention, and FIG. 1 shows a 2×2
Figure 2 shows the 3X3 mold first block 2.
, Fig. 3 shows the 2X1 type second block 12, and Fig. 4 shows the 3
The X1 type second block 13 is shown.

First, the 2×2 type first block 1 shown in FIG. 1 is constructed as follows.

In other words, the vertical distance between the two sides facing each other on the bottom surface is t, t-
The hollow octagonal pillars 3, which are regular octagons of 2t and have a height of t, are arranged in a lattice pattern of two vertically and two horizontally, and their adjacent side walls are joined to form a 2X2 type hollow composite octagonal pillar. , all of the four joining walls 3a are removed to form a 2×2 type hollow columnar body 4.

At this time, each of the four insertion ports 5 of the 2×2 type hollow columnar body 4 has six sides of a regular octagon with a vertical distance of t-2t between the two opposing sides.

Furthermore, when viewed from the bottom surface of the 2×2 hollow columnar body 4, connecting walls 8 are integrally formed between the soil walls 7a, between the bottom walls 7b, and between the side walls 7c of the insertion port 5, and the connecting walls 8 The upper surface of the space formed by the oblique side wall 7d of the insertion port 5 is closed, and at the same time, the upper surface of the space surrounded by the four hollow octagonal columns 3 is also closed.

Further, a cylindrical portion 6 having a height h((A) and a diameter t-2t is integrally formed on the upper surface of each of the insertion opening portions 5).

Moreover, the 3×3 type first block 2 shown in FIG.
It can be constructed almost in the same way as the first block 1 of the mold.

That is, this 3x3 type first block 2 has the hollow octagonal pillars 3 arranged in a grid of 3 vertically and 3 horizontally to form a 3x3 hollow pillar 9. You can do exactly the same thing.

However, in this block 2, the nine insertion openings 10, 11, 5 of the 3×3 hollow columnar body 9 are connected to the 4th, 5th, or 6th side of a regular octagon with a vertical distance of t-2t between the two opposing sides. It has become something that we have.

Furthermore, in the present invention, by arranging mXn hollow octagonal pillars 3 in a lattice shape, and performing the same operation as above, m
An Xn-type first block can be constructed, and each of the insertion openings of the block has four, five, or six sides of a regular octagon with a vertical distance of t-2t between the two opposing sides.

Since the mxn type first blocks (m and n are both integers of 2 or more) each have a cylindrical part 6, these blocks can be inserted into each other (from this point, these blocks can also be used as a second block). However, the block that should be inserted into the insertion opening of the first block is the mXn type block as described above.

Even if n is not both 2 or more, Figures 3 and 4
Of course, blocks like the one shown in the figure can also be inserted.

That is, the 2X1 type second flock 12 shown in FIG.
In the n-type first block, m is 2 and n is 1, and the 3X1-type second block 13 shown in FIG.
is 3, and n is 1.

Furthermore, by setting the number of i to an arbitrary number, iXl
A second block of the mold can be constructed.

And the mXn type 170 tsukku (m.

n is an integer of 2 or more) and iXl type second blocks are provided for each value of nlt nt l to form a block toy, various structures can be assembled by combining the various blocks described above. , FIG. 5 shows an assembled animal model as an example.

In the figure, 20 is a 6×6 type first block.

Next, the effects will be explained.

In the first blocks 1 and 2 of the above embodiment, the insertion port 10
, 11.5 have a regular octagonal shape with 4 sides, 5 sides, or 6 sides.
5 and the columnar part 6, the insertion opening parts 1o, ii
, s and the outer surface of the cylindrical part 6 come into contact at 4, 5, or 6 points, and there is no surface contact like the fitting between a circular protrusion and a circular insertion opening, so children However, they can be easily inserted and removed, so they hardly wear out even after long-term use.

In addition, as mentioned above, the insertion opening part 10°11.5 and the cylindrical part 6
Since they are in point contact at 4, 5, or 6 points, the cylindrical part 6 will not easily come out of the insertion opening part 10° 11.5, and the fitting strength will be moderate. .

Furthermore, the bottom shape of the mXn type first block in this example is me.
Since n is both 2 or more, there is always a shape 30 that is a square rotated by 45 degrees, as shown in Figure 1 d and Figure 2 C, which is extremely simple and beautiful. be.

In the 2×2 type first block and the 3×3 type first block of the above embodiments, a connecting wall was provided between the soil walls and the bottom wall of the insertion port, but this connecting wall may be omitted.

In addition, in the above embodiment, the first block has all cylindrical parts and can therefore be said to be the second block, but the first block in the present invention has mXn inserts. It is only necessary to include a hollow columnar body having a mouth portion, and the columnar portion may not be provided.

Also, as an example of the second block, only a hollow octagonal column with a cylindrical part protruding from the top has been mentioned, but the second block in the present invention is a block that fits into the insertion opening of the first block. The shape of the other portions is not limited at all as long as they have cylindrical portions that meet.

As described above, according to the present invention, mXn hollow octagonal pillars with regular octagonal cross-sectional shapes are arranged in a lattice pattern, and all the joint walls of the hollow composite octagonal pillar are removed by joining the adjacent side walls. As a result, an insertion opening having a completely new bottom shape is formed, which has the effect of simplifying the structure of the insertion opening, providing appropriate fitting strength, and being aesthetically beautiful.
