Description

[Detailed explanation of the idea] The present invention relates to a building block piling tool.

In general, building blocks are toys for young children that are made by stacking building blocks such as rectangles, cylinders, cubes, and triangular prisms to create various three-dimensional structures. Building pile tools have been proposed and implemented in which a wide variety of shapes can be created by drilling holes and connecting round rods by inserting them into the holes.

Among these building blocks, some that are particularly popular among young children are vehicles with wheels such as buses and trucks.
Normally, a thin cylindrical building block is used as a wheel, a round bar-shaped building block is used as an axle, and both ends of the block are fitted into holes provided in the wheel piece, and another building block is fitted appropriately in the center of this axle. They are then stacked together to form the vehicle body.

However, when making a vehicle by fitting and connecting multiple blocks using round blocks,
When making other products, it is necessary to make the fitting state different.

This is because when building a three-dimensional object other than a vehicle, if the other building blocks are not fitted slightly tightly to the round block-shaped building blocks, they will fall off and cannot be assembled properly. This is because when making a wheel, at least one of the round bar-shaped building blocks and the building blocks constituting the wheel or vehicle body must be loosely fitted to the round bar in order for the wheel to rotate smoothly.

On the other hand, conventional building blocks have two different diameters:
When making a vehicle, as a combination of round bar-shaped building blocks of different types and building blocks with insertion holes of the same diameter for large-diameter round bar-shaped building blocks, small-diameter round bar-shaped building blocks are used, or On the other hand, when building a vehicle by combining two types of building blocks with different hole diameters and a round bar-shaped building block with a small diameter, a round bar-shaped building block and a round bar-shaped building block with an insertion hole of the same diameter are used. It was decided to use building blocks with large hole diameters.

However, since there is only a small difference in the diameter of the round blocks and the hole diameter of the blocks, it is difficult for young children to choose one.

Moreover, when manufacturing building block pieces of various diameters as described above, the diameters must be delicately adjusted and many molds are required, which increases the cost.

The object of the present invention is to solve the above-mentioned drawbacks, and to propose a building block piling tool that can easily produce a vehicle that can run particularly smoothly and is inexpensive.

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

In FIGS. 1 and 2, reference numeral 1 indicates a round bar-shaped building block according to the present invention.

This round bar-shaped building block piece is constructed as a hollow body made of synthetic resin.

Four ribs 2 are provided at regular intervals in the longitudinal direction of the curved surface of the round bar 1.

In this case, the height of the ribs 2a on both sides of the round bar 1 is formed to be larger than the height of the ribs 2b at the center.

Note that the maximum width of the cross section of the round bar 1 including the ribs 2a on both sides (hereinafter referred to as maximum width) is larger than the maximum width of the round bar 1 including the ribs 2b in the center, and As long as some of the maximum widths on both sides of the bar 1 are larger than the maximum width at the center, the number and shape of the ribs may be configured in any manner.

On the other hand, a round bar insertion hole having a diameter approximately equal to the maximum width on both sides of the round bar 1 is formed in the building block piece.

When building a vehicle using the round bar-shaped building block 1 having the above structure and other building blocks 3.4, first insert the round bar 1 into the hole 3a of the building block 3 that is to be a part of the vehicle body. Place it in the center of the rod.

At this time, since the maximum width of the central part of the round bar 1 is smaller than the hole diameter of the building block piece, the round bar 1 and the building block piece 3 are loosely fitted in this position.

Next, building blocks 4 to be used as wheels are fitted to both sides of the round bar 1.

In this case, the maximum width of the round bar 1 including the ribs 2a on both sides is approximately equal to the diameter of the hole 4a of the building block piece 4, so the round bar 1 and the building block piece 4 are fitted rather tightly.

In this way, the round bar 1 fits loosely into the car body 3, but it fits slightly tightly into the wheels 4, so when the car body 3 is pushed, the round bar 1 will idle with respect to the car body 3. While rotating, the vehicle rotates together with the wheels 4 and runs smoothly.

Moreover, the wheel 4 never comes out from the round bar 1.

Furthermore, if the round bar according to the present invention is used, building blocks will not fall off from the round bar even when making something other than a vehicle.

This is because, while the maximum width of this round bar is small at the center, the hole diameter of the building blocks is approximately equal to the maximum width on both sides of the round bar. This is because the fit is always a little tight in some areas.

In addition, as mentioned above, since the ribs 2 are formed in the longitudinal direction of the circumferential surface of the round bar-shaped building block piece 1, the strength of the building block piece 1 is increased, and it can also be inserted into the insertion hole of another building block piece. In this case, a slight gap is formed between the insertion hole of the building block piece and the circumferential surface of the round bar-shaped building block piece 1 other than the rib 2.

Therefore, even if the hole diameter of this building block piece is formed smaller than the maximum width on both sides of the round bar-shaped building block piece due to a molding error, since the round bar-shaped building block piece 1 is formed as a hollow body made of synthetic resin, Due to its elasticity, the rib 2 is elastically deformed and escapes into the gap, so that the fitting state between the round bar and the block piece becomes good.

As explained in detail above, according to the present invention, various solid objects, including vehicles, can be stacked up using only one type of round block-shaped building blocks, and even in the production process, the hole diameter of the building blocks and the maximum diameter of the round blocks can be stacked up. Since there is no need to adjust the size according to the type, the cost is also reduced.
