Description

[Detailed explanation of the invention] This invention relates to a block toy that is ideal as a so-called educational toy that is useful for emotional education of young children and the cultivation of ingenuity. The present invention relates to a toy of this kind in the form of blocks that can create a desired structure, such as an airplane, a ship, or a house, by combining a plurality of bodies in an arbitrary manner.

Conventionally, this type of block toy has a block body with a plurality of protrusions formed on the surface and a hole for fitting the protrusions on the back side. Structures are created by combining unit blocks by fitting them into holes or protrusions, but it has become possible to create structures of your choice by changing the way the unit blocks are combined, that is, the way the blocks fit together. ing.

In other words, various structures can be created depending on how much the fitting hole of one block body is fitted to the plurality of protrusions on the other block body, how much they overlap and at what angle, and how many block bodies are used. It is now possible to create

However, in block toys made only of this type of combination, the back side of the fitting hole is always exposed to the surface of the protrusion, so the fitting direction is only vertical. Therefore, it had a certain limit in shape.

Moreover, when fitting wheels together, for example, the small hole for inserting the axle must be drilled in the side of the block body.
On the back side of the block body, there is no choice but to form a fitting hole that can fit into the protrusion of another block body, and at the same time to adopt a special holding structure that maintains the rotational position of the wheel. The block toy has a different type, which not only leads to an increase in the number of parts, but also the original meaning of block toys as toys, that is, the various shapes that are made of the maximum number of combinations with the minimum number of parts. When I considered whether or not it was possible to create it, I was still not satisfied with it.

Therefore, the purpose of this invention is to enable vertical mating combinations in which the front and back surfaces are always exposed in a normal unit block body, as well as horizontal mating combinations in both left and right directions in which only the front surfaces are exposed. To provide a block toy that can be combined, that is, connected and combined between fitting holes, and can be easily combined with wheels without increasing the number of parts.

Its features are 1. A block body with multiple protrusions on the front surface, a hole for fitting the protrusions on the back surface, and a small hole penetrating between the front and back surfaces; A connecting body that fits into the fitting hole and connects the separate block bodies;
It is constructed in combination with a wheel body having an axle portion having a substantially arrow-shaped locking portion at the shaft end that can be easily inserted into the small hole and can be controlled to be released after insertion.

The aspects of this invention will be specifically explained below with reference to an example of implementation.

FIG. 1 is a perspective view showing how block toys are assembled when making a four-wheeled vehicle. 1 has a plurality of protrusions 2 at approximately the same height on the front surface, and fitting holes 3 for the protrusions 2 on the back surface. It is a block body having a block body, and is assembled by fitting the protrusion 2 or the fitting hole 3 into the fitting hole or protrusion of a separate block body.

Reference numeral 4 denotes small holes for mounting a wheel body 6, which will be described later, which are bored between the protrusions and between the front and back surfaces, and two are formed per unit block body.

Reference numeral 5 denotes a connecting body that fits into the fitting hole 3 of the block bodies and connects the block bodies, and has a hollow cylindrical shape.

6 is a wheel body mainly composed of an axle portion 6a and a wheel 6b, and a substantially arrow-shaped locking portion 6C is formed at the shaft end of the axle portion 6a.

As shown in FIG. 2, the shaft diameter of the axle shaft portion 6a is slightly smaller than the small hole of the block body at the center of the shaft, and the diameter of the stepped portion 6d of the locking portion 6C at the shaft end is the same as that of the small hole 4. It has a slightly larger diameter.

Further, the axial length from the stepped portion 6d to the wheel 6b, that is, the axial length at the center of the shaft, is approximately equal to the length of the small hole 4 plus the height of the protrusion 2.

Therefore, when attaching the wheel body 6 to the block body 1, since the locking portion 6C at the shaft end is tapered in the shape of an arrow,
It can be easily inserted into the small hole 4 even by a child with a weak force, and once the liquid is filled, the locking part 6C
It can be locked very easily by the stepped portion 6d.

Moreover, the rotational position of the wheel 6b is maintained by the stepped portion 6d and the plurality of protrusions 2 that come into contact with the back surface of the wheel with play, and as described above, the axle portion 6a
Since the shaft diameter at the center of the shaft is smaller than that of the small hole 4, it is rotatable.

By the way, although the connecting body 5 has a hollow cylindrical shape as described above, it may also have a solid shape such as a solid columnar shape.

However, considering the ease of mating and unmating to the mating hole 3,
A hollow cylindrical connecting body 5 having inherent elasticity is preferred;
Furthermore, if the wheel body is attached to a solid cylindrical shape, the length of the connecting body will be subject to a certain limit due to the locking part 6c protruding into the fitting hole 3, and a strong connection will be achieved. It is considered that a hollow cylindrical connector that can be used in a length that is estimated to be possible, that is, twice the depth of the three fitting holes, is appropriate.

The shape of the connecting body is not limited to a thermal cylinder or a cylinder, and the shape of the connecting body may be specified depending on the shape of the fitting hole of the protrusion of the block body.

In addition, the block body 1 is inserted into the outer periphery of the connecting body 5.
, 1 can also be used by attaching a joint member 7 as shown in FIG.

This joint member is the connecting body 5 in this embodiment.
It has a shape with two holes 8 and 8' for insertion into the hole, and is attached like a so-called gasket.

For example, by inserting one fitting hole 8 into the connecting body 5 and fitting the other fitting hole 8' into a connecting body related to a separate four-wheeled vehicle, a double connection can be made. It goes without saying that by using this combination method, it is possible to connect any number of layers or layers.

Further, for example, if the other fitting hole 8' is provided vertically to the vehicle body of a four-wheeled vehicle and separate parts are attached to the fitting hole 8, vertical combination can be performed.

Alternatively, for example, instead of the other insertion hole 8', a part such as a doll can be directly shaped, or its attachment part can be formed, or the neck part between the insertion holes 8 and 8' can be directly shaped. By using a joint member constituted by the insertion hole 8 and providing a neck portion with the function of allowing parts such as dolls to be inserted into the joint member, the number of combinations can be dramatically increased.

Further, in this embodiment, two small holes 4 for mounting the wheel body are formed per unit block body, but it is needless to say that the present invention is not limited to this.

In this embodiment, the axle shaft portion 6a is integrally formed with the wheel 6b and constitutes a part of the wheel body 6, but it may also be formed separately and combined with the wheel 6b to constitute a wheel body, for example.

That is, an insertion hole for the axle is provided in the center of the wheel 6b, a recess is formed around the insertion hole on the wheel surface, and an axle with a wheel-shaped portion that can be fitted into this recess is combined. A splittable wheel body can be obtained.

As described above, the block toy according to this invention has a block body formed by forming a plurality of protrusions on the front surface, forming a fitting hole for the protrusions on the back surface, and having a small hole penetrating between the front and back surfaces. , a connecting body that fits into the fitting hole to connect the separate block bodies, and an axle portion having a substantially arrow-shaped locking portion formed at the shaft end, and the rotational position of the wheel is between the tapered portion and the axle portion. Since it is composed of a combination with a wheel body held by a protrusion, it is of course possible to perform a vertically mating combination in which the front and back surfaces are always exposed like with conventional block bodies, but only the front surface is exposed. Lateral mating combination in both left and right directions,
In other words, in addition to making it possible to connect and combine the fitting holes,
This eliminates the need for parts such as blocks that require a special holding structure to hold the rotational position of the wheel when installing the wheel.

Therefore, it is possible to prevent an unnecessary increase in the number of parts, to provide a block toy that has an extremely simple shape and can be assembled in complex ways.
