Description

[Detailed description of the invention] This invention relates to a doll equipped with joints that utilize the attraction force of a magnet.

In the case of dolls that use the attraction force of conventional magnets to removably attach parts such as the head, arms, and legs, yokes are magnetically joined to both sides of a single permanent magnet. A recess is provided at the edge of the yoke to constitute an adsorbent, and an iron ball protruding from the connecting end of the attached member is fitted into the recess and adsorbed to perform the same function as a joint.

However, the adsorbent used to be a single permanent magnet with yoke attached to both sides, and this was used to attract and hold the head, both arms, and both legs, so the following method was used: There was a drawback.

That is, first, since all the attached members attached to the doll at discrete positions corresponding to the vertices of the pentagon are to be attracted by a single permanent magnet, the attraction area must be large.

By the way, the attractive force of a magnet is proportional to the square of the magnetic flux and inversely proportional to the attraction area.

Furthermore, it is difficult to manufacture a permanent magnet that has a large attraction area and a sufficiently large attraction force.

Therefore, because the conventional product uses a single suction body, it is difficult to apply an equal suction force to each member to be attached, resulting in unevenness, and it is easy for one of the members to be attached to It has the disadvantage of falling, and as the doll gets larger, the suction force at the joints decreases.

Second, in the first place, it is difficult for a permanent magnet to attract the iron ball of the attached member through a yoke, to rotate the attached member in the attracted state, or to repeat the attraction and separation process. This is a cause of significant demagnetization, as the yoke is joined to a permanent magnet shaped to be accommodated in a narrow space, such as the body of a doll, and the iron ball is repeatedly separated from the yoke. , the demagnetization rate is relatively high, and as mentioned above, the attraction area is large, so the attraction force is originally small.
There is a drawback that when the suction force decreases at an early stage and one member to be attached is attached, subsequent members to be attached cannot be reliably attracted.

Thirdly, since the suction body is a single body with connecting recesses for the head, both arms, and both legs, its length or size remains constant, so it can be applied to dolls of various sizes. In order to accommodate this, it is necessary to manufacture and prepare adsorbents of various sizes, which is uneconomical in terms of component management and manufacturing costs.

The purpose of this invention is to eliminate the drawbacks of the conventional products mentioned above.

Next, one embodiment of this invention will be described based on the drawings.

Reference numeral 1 denotes the front half of the doll's body, which is butted against and joined to the rear half (not shown) to form the body.

Both the first half 1 and the second half include the doll's head 2 and arms 3.
It has semicircular recesses 1a, 1b, and IC in the parts to which attached members such as the legs 4 are connected, and when the front half and the rear half are butted and combined, these recesses Thus, circular holes are formed into which the connecting ends of the head 2, arms 3, and legs 4 can be fitted, respectively.

Hereinafter, the front half 1 will typically be referred to as the trunk.

The members to be attached, such as the head 2, arms 3, and legs 4, are each attached to the torso 1 removably, so steel balls are attached to the connecting ends, that is, the base ends corresponding to the joints. , or an iron piece 5a having a spherical surface, such as a round head iron screw,
5b and 5C are provided protrudingly.

In this invention, the torso 1 includes a chest 1B and a waist 1H.
on the inside of the chest and on the inside of the waist, that is, between the front half and at a position corresponding to the arms and the waist,
Separate adsorbents 6B and 6H are buried therein.

The adsorbent body 6B on the chest is made by joining yokes 8 and 9 to both sides of a permanent magnet 7, and the yokes 8 and 9 have the same shape and have their edges extended from the permanent magnet. The iron piece 5a of the head 2 and the iron piece 5b of the left and right arm parts 3 are placed on the upper part and both left and right sides of the
Concave arcs 8 a , 8 b , 9 a corresponding to the spherical surfaces of
, 9b, and when the yoke is connected to the permanent magnet 7, the concave arcs 8a8b, 9a, 9 of each yoke are
b are adjacent to each other to form a pair, forming a connecting recess.

The absorbent body 6H on the waist is also similar to the absorbent body 6B on the chest,
Yokes 11 and 12 are joined to both sides of a permanent magnet 10,
The yokes 11 and 12 have the same shape and have concave arcs 11C and 12C corresponding to the spherical surface of the iron piece 5C of the leg portion 4 on both left and right sides of the end edge extending from the permanent magnet. , with the yoke connected to the permanent magnet, the arc 11C of each yoke,
12C are adjacent to each other to form a pair and form a connecting recess.

Connection recesses 8 a , 9 a of the adsorbent body 6B on the chest,
The iron piece 5a of the head part 2, the iron piece 5b of the arm part 3, and the iron piece 5C of the leg part 4 can be fitted into the connecting recesses 11C of the absorbers 8b, 9b and the waist part 6H, respectively. , each piece of iron is attracted to the yoke.

In this way, a joint is formed by each connecting recess and the iron piece fitted therein.

The adsorbent body 6B on the chest has connection recesses 8a, 9a, 8.
b and 9b are attached inside the chest with the connecting recesses 11C and 12C facing the outside through the circular holes on the left and right sides of the waist, respectively, and the absorber 6H on the waist is attached to the chest with the connecting recesses 11C and 12C facing the outside through the circular holes on the left and right of the waist. It can be attached inside the waist.

Therefore, the head 2, the arms 3 and the legs 4 each have an iron piece 5.
a, 5b, and 5C can be fitted into the four connecting parts and adsorbed, and can be detachably attached.

As described above, the absorbent body is divided into the chest absorbent body 6B and the waist absorbent body 6H, and each absorbent body 6B, 6H has a head portion 2 and a head portion located relatively close to each other corresponding to the vertices of the triangle. Since the left and right arms 3 and the left and right legs 4 placed close to each other are separately attracted, the permanent magnet of each attracting body can be attached to a pentagonal shape with a single attracting body as in the past. It is possible to use a device with a much smaller attraction area than when all the attached members placed at the apex are attracted, and it is therefore easier to concentrate the magnetic flux in the adjacent connecting recesses. The suction force of the adsorbent increases significantly.

Therefore, it is also possible to reduce the influence of demagnetization caused by repeated adhesion and separation of the iron pieces 5a to 5C.

In addition, since the adsorbent is divided into parts corresponding to the chest and waist, the same size adsorbent can be used even if the length of the torso is different. Therefore, component management is easy and manufacturing costs are reduced. Can be reduced.

As described above, according to this invention, it is possible to securely attach the attached member by providing a joint with a sufficiently large adsorption force, and the influence of demagnetization due to the attachment and detachment of the attached member is reduced. In addition, it is possible to provide a doll in which suction bodies of the same size can be used for body parts of various lengths.
