Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block toy in which one or more mounting bodies can be detachably mounted by magnetic force on a block body made of a magnetic material.

[0002]

2. Description of the Related Art Conventionally, a doll toy as disclosed in Japanese Patent Publication No. 57-2358 is known. This doll toy has a body part which is entirely made of a ferromagnetic material and whose upper part is formed in a spherical shape, and a head part which is made of a ferromagnetic material and whose lower part is formed in a spherical shape. The magnet is interposed between the body and the head so that the magnetic force of the magnet connects the body and the head. The upper surface of this magnet, that is, the surface corresponding to the head is formed in a concave spherical shape having a radius of curvature equal to the radius of curvature of the spherical surface of the head. Similarly, the lower surface of the magnet, that is, the surface corresponding to the body portion is formed into a concave spherical surface having a radius of curvature equal to the radius of curvature of the spherical surface of the body portion.

[0003]

In the above-mentioned conventional example, the body portion is spherical, and if an existing flat plate-shaped magnet is used as the magnet, the attraction surface between the body portion and the magnet becomes point contact, and the attraction force is increased. Therefore, in order to increase the contact area and maintain the attraction force, it is considered that the magnet is formed in a concave spherical shape having a radius of curvature equal to the radius of curvature of the spherical surface of the body portion. However, in order to match with a specific spherical surface, a magnet having a concave spherical surface with a specific radius of curvature had to be specially processed. Therefore, there is a problem that the cost of the magnet component is increased, which increases the cost of the toy as a whole.
Therefore, it is conceivable to use a ready-made flat magnet housed in the yoke in order to compensate for the insufficient magnetic force of the magnet and to secure the attraction force with the body while suppressing the cost of the magnet component. However, while using a yoke can compensate for the lack of magnetic force of the magnet, the attraction surface with the body part is in linear contact, and the contact area is extremely small, so the mounted body slides on the curved surface of the body part with a small impact. Therefore, there is a problem that the mounted body cannot be held at a predetermined position. Further, it is possible to solve the above-mentioned problems by using a magnet having a strong magnetic force such as a rare earth magnet, but the magnet having such a strong magnetic force has a high cost, which rather increases the cost of the toy as a whole. Had the problem.

The present invention has been made in view of the above-mentioned problems, and the cost is reduced by using a ready-made flat magnet without using a magnet having a special shape. An object of the present invention is to provide a block toy capable of detachably attaching a body to a block body and securely holding the attached body at an arbitrary position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings. First, the overall configuration of the block toy 1 will be described with reference to FIGS. 1, 2, and 3. Block toy 1
Is composed of a spherical block body 3 made of a magnetic material, and a plurality of mounting bodies detachably mounted on the block body 3. That is, the head 5 is mounted on the upper part of the block body 3, and the pair of arm parts 7,
9 is attached to the bottom of the block body 3 and the pair of legs 1
1, 13 are attached. The head 5, the pair of arms 7 and 9, and the pair of legs 11 and 13 are formed of a relatively lightweight member such as a synthetic resin, and their weights take into consideration the attraction force of the magnetic attraction unit described later. And set appropriately. Further, as shown in FIG. 3, one leg 11 has an upper leg 15 and a lower leg 1.
7 and a shaft 19 connecting the upper leg 15 and the lower leg 17. The upper leg 15 is provided with a hole 15a and the lower leg 17 is provided with holes 17a, 17b. By inserting the shaft 19 into the holes 17a, 15a, 17b, the upper leg 15 is moved to the lower leg 17. Be connected. Further, since the inner diameters of the holes 15a, 17a, 17b are set to be equal to or slightly larger than the outer diameter of the shaft 19, the upper leg portion 15 can rotate about the shaft 19 and appropriately. Is held in the rotating position. Also, the configuration of the other leg 13 is also shown in FIG.
The detailed description is omitted here.

A magnetic attraction portion is formed on each of the plurality of mounting bodies. That is, the head portion 5, the pair of arm portions 7 and 9, and the pair of leg portions 11 and 13 are respectively formed with magnetic attraction portions 5a, 7a, 9a, 11a and 13a. Next, the magnetic attraction section 5a provided on the head 5 will be described in detail with reference to FIG. The magnetic attraction portion 5a is composed of a yoke 21 having a recess, an existing flat plate-shaped magnet 23 housed in the yoke 21, and a non-slip member 25 fixed onto the magnet 23. The shape of the bottom surface of each of the yoke 21 and the magnet 23 housed in the yoke 21 may be circular, square, or the like.
An appropriate shape is used. Recess edge 2 of the yoke 21
The height of 1a is set to be larger than the thickness of the magnet 23. The non-slip member 25 fixed on the magnet 23 is made of an elastic synthetic resin material, for example,
It is made of foamed polyurethane, and its tip is the yoke 2.
It projects outward from the concave edge 21a of No. 1. Therefore, when the magnetic attraction portion 5a is attracted to the block body 3, the tip of the anti-slip member 25 is compressed into the yoke 21 by the spherical surface of the block body 3. In addition, another wearing body, that is, a pair of arm portions 7 and 9 and a pair of leg portions 11 and 1
3, each magnetic attraction portion 7a, 9a, 11
The configurations of a and 13a are similar to those of the magnetic attraction portion 5a, and detailed description thereof will be omitted.

Although the plurality of mounting bodies are provided in the embodiment shown in FIGS. 1 and 2, only a single mounting body may be removably mounted on the block body 3. Also,
The block body 3 is not limited to a spherical shape and can be formed in an appropriate shape. For example, the overall shape of the block body 3 may be formed into a rectangular parallelepiped, and only a specific portion where the mounting body is mounted may be formed into a spherical shape according to the number of mounting bodies.

Next, the operation of the embodiment according to the present invention will be described. Head 5, pair of arms 7, 9 and pair of legs 11, 13
In the magnetic attraction sections 5a, 7a, 9a, 11a,
13 a is formed, and one or more of these mounting bodies are removably mounted on the block body 3. Each magnetic attraction unit has a yoke having a concave portion, a flat magnet housed in the yoke, and a non-slip member fixed on the magnet. With this configuration, a magnet having a special shape is not required, and the magnetic attraction portion is formed by using an existing plate magnet.

Next, referring to FIG. 5, the operation when the head 5 is attracted to the block body 3 will be described. The height of the recess edge 21a of the yoke 21 is set to be larger than the thickness of the magnet 23, and the non-slip member 25 fixed on the magnet 23 is formed of expandable polyurethane which is a synthetic resin material having elasticity. This non-slip member 2
Since the tip end of 5 is projected outward from the concave edge 21a of the yoke 21, when the magnetic attraction portion 5a is attracted to the block body 3, the tip end of the anti-slip member 25 enters the yoke 21 due to the spherical surface of the block body 3. Compressed. As the anti-slip member 25 is pressed in this way, the frictional force between the magnetic attraction part 5a and the block body 3 becomes large, and the head 5 can be reliably held at an arbitrary position. Therefore, even when the head 5 is replaced or the magnet 23 is moved and rotated in order to change its position and orientation, the head 5 can be reliably held at an arbitrary position. Further, the action of adsorbing the pair of arm portions 7 and 9 and the pair of leg portions 11 and 13 which are other mounted bodies to the block body 3 is also similar to the above, and thus detailed description thereof will be omitted. As described above, one or two or more mounting bodies can be removably adsorbed to the block body 3, the position and the direction thereof can be easily changed, and these mounting bodies can be reliably held at any position. it can.

The embodiment according to the present invention is not limited to the above, and can be applied as it is to animal toys, automobile toys, or appropriate robot toys.

As described above, according to the present invention, a magnetic attraction portion is formed in each of the one or more attachment bodies detachably attached to the block body, and each magnetic attraction portion has a concave portion. It has a yoke, a flat magnet housed in the yoke, and a non-slip member fixed on the magnet. As described above, the effect that the cost can be reduced can be achieved by using the existing plate-shaped magnet without the purpose of using the magnet having the special shape. Further, the height of the recess edge of the yoke is set to be larger than the thickness of the magnet, and the anti-slip member fixed onto the magnet is formed of a synthetic resin material having elasticity, and the tip of the anti-slip member is attached to the yoke. Since it is configured to project outward from the edge of the recess, the tip of the anti-slip member is compressed into the yoke by the spherical surface of the block body when the magnetic attraction section is attracted to the block body. Then, the anti-slip member is pressed against the spherical surface of the block main body, and the frictional force of the anti-slip member securely holds the mounted body at an arbitrary position without sliding on the spherical surface. Therefore, it is possible to easily change the position and the direction of the one or more mounting bodies that are attracted to the block body by the magnetic force, and it is possible to reliably hold the position and the orientation at the changed appropriate position.
