Description

本発明は、人形（素体含む）の頭部を頸部に連結するための連結構造に関する。 The present invention relates to a connecting structure for connecting the head of a doll (including a body) to the neck.

昨今の人形には、頭部を着脱可能に構成されているものがあり、例えば、１体（１個）の人形で、様々なキャラクタを演出して遊びたい場合など、表情を変えるため頭部を交換したりする場合がある。すなわち、頭部を交換するのみで、様々なキャラクタに変えることができ、コストを掛けずに需要者の興趣を向上することができる。 Some dolls these days have a removable head. For example, when you want to play with various characters with one doll, you can change the head to change the facial expression. May be replaced. That is, it is possible to change to various characters simply by exchanging the head, and it is possible to improve the interest of the consumer at no cost.

ところで、人形や人形の頭部の制作会社（販売会社）によって、頭部などの外皮を構成するソフトビニル樹脂などの肉厚は、厚いもの薄いもの様々である。
従来、人形の頭部を連結する構造として、特許文献１に開示の関節構造が提案されている。しかし、特許文献１に開示の人形構造にあっては、頭部の変更による興趣の向上を目的として成されているものではなく、肉厚の薄厚に対応し得ない構造であった。 By the way, depending on the production company (sales company) of the doll or the head of the doll, the wall thickness of the soft vinyl resin or the like constituting the exodermis of the head or the like varies from thick to thin.
Conventionally, a joint structure disclosed in Patent Document 1 has been proposed as a structure for connecting the heads of dolls. However, the doll structure disclosed in Patent Document 1 is not designed for the purpose of improving the interest by changing the head, and is a structure that cannot cope with the thin wall thickness.

そこで、本発明者等は、特許文献２に開示の連結構造を先に提案している。
特許文献２に開示の頭部の連結構造は、円筒状に形成された頸部本体と、頸部本体内を、人形の高さ方向に出没可能で、先端に大径の押え部を備えた棒状の摺動部とで構成し、摺動部はコイルスプリングによって、常時押え部を頸部本体側へと引寄せ可能に構成している。そして、頭部の下面に形成されている押え部よりも小径の連結孔部を押し広げるようにして押え部を嵌め入れていた。押え部は、コイルスプリングの復元力により頸部本体方向に引寄せられるため、その引寄せる力によって頭部の連結孔部周囲を、押え部と頸部本体とによって挟み込んで固定させる構造である。 Therefore, the present inventors have first proposed the connection structure disclosed in Patent Document 2.
The head connection structure disclosed in Patent Document 2 has a cylindrical neck body and a neck body that can appear and disappear in the height direction of the doll, and has a large-diameter pressing portion at the tip. It is composed of a rod-shaped sliding portion, and the sliding portion is configured so that the pressing portion can always be pulled toward the neck body side by a coil spring. Then, the pressing portion was fitted so as to expand the connecting hole portion having a diameter smaller than that of the pressing portion formed on the lower surface of the head. Since the holding portion is pulled toward the neck body by the restoring force of the coil spring, the pulling force has a structure in which the circumference of the connecting hole of the head is sandwiched and fixed by the holding part and the neck body.

このような構成を採用したため、コイルスプリングの伸長範囲で押え部と頸部本体との間の頭部連結孔部周囲を挟み込む間隔（隙間）が広狭調整可能である。従って、頭部外皮の肉厚に左右されずに頭部を差し替えることが可能であるため、頭部を変えることにより、異なるキャラクタを簡単に表現でき大変有用である。 Since such a configuration is adopted, the interval (gap) for sandwiching the circumference of the head connecting hole between the pressing portion and the neck body can be adjusted within the extension range of the coil spring. Therefore, since the head can be replaced regardless of the thickness of the exodermis of the head, it is very useful to easily express different characters by changing the head.

しかし、特許文献２の場合において頭部を交換するには、次のような課題を有していた。
コイルスプリングの復元力に抗して押え部を引き上げるとともに、連結孔部を押し広げるようにして押え部を頭部内から抜き外して頭部を分離する必要がある。また、別個の頭部を差し替える場合にも、連結孔部を押し広げるようにして押え部を頭部内に嵌め入れるとともに、コイルスプリングの復元力に抗して押え部を引き上げ、押え部と頸部本体との間に形成される頭部連結孔部周囲を挟み込む間隔（隙間）を広くして挟み込む必要がある。
このような作業は、多大な労力を要するとともに作業手間が掛かり大変面倒である。 However, in the case of Patent Document 2, exchanging the head has the following problems.
It is necessary to pull up the presser foot against the restoring force of the coil spring and to separate the head by pulling out the presser foot from the inside of the head by expanding the connecting hole. Also, when replacing separate heads, the presser foot is fitted into the head by expanding the connecting hole, and the presser foot is pulled up against the restoring force of the coil spring to pull up the presser foot and neck. It is necessary to widen the interval (gap) for sandwiching the circumference of the head connecting hole formed between the portion and the main body.
Such work requires a great deal of labor and labor, and is very troublesome.

そこで本発明者等は、さらに改良を加え、特許文献３に開示の連結構造を提案している。 Therefore, the present inventors have further improved and proposed the connection structure disclosed in Patent Document 3.

特許文献３に開示の連結構造は、人形の胴部から突出した頸部と、頸部の一部を頭部内にて係止可能な被係止部とで構成されている。頭部に備えた挿入孔部は、挿入可能な頸部の一部の外径よりも大径で、頸部の一部が挿入可能な径をもって形成されている。
頸部は、頭部の挿入孔部に挿入可能な薄板状の係止部と、係止部を上下移動かつ左右回転可能に上端に備える頸部本体と、係止部を常時頸部本体方向に引き寄せて、係止部を上下方向に伸縮可能なスプリングとで構成されている。一方、被係止部は、頭部内に配され、頭部の挿入孔部内周縁に当接可能な当接面と、頭部内にて、挿入孔部を介して挿入された係止部を挿通可能な平面視で矩形状の挿通孔部と、弾性部材の弾性に抗して上方に引き上げるとともに、左右何れかの方向に９０度回転させた係止部を、挿通孔部からずらして係止する受け部とで構成されている。
すなわち、係止部を、挿入孔部及び被係止部の挿通孔部を介して頭部内に挿入し、その後、係止部をスプリングの復元力に抗して上方に引き上げるとともに、左右何れかの方向に９０度回転させて受部に係止させる。これにより頭部内にて頸部の一部である係止部の先端が係止され、頭部が着脱可能に連結されるものである。 The connecting structure disclosed in Patent Document 3 is composed of a neck protruding from the body of the doll and a locked portion capable of locking a part of the neck in the head. The insertion hole provided in the head is formed to have a diameter larger than the outer diameter of a part of the neck that can be inserted and a diameter that allows a part of the neck to be inserted.
The neck has a thin plate-shaped locking part that can be inserted into the insertion hole of the head, a neck body that has a locking part at the upper end that can move up and down and can rotate left and right, and a locking part that is always in the direction of the neck body. It is composed of a spring that can be pulled in and expands and contracts in the vertical direction. On the other hand, the locked portion is arranged in the head and has a contact surface capable of contacting the inner peripheral edge of the insertion hole portion of the head and a locking portion inserted in the head via the insertion hole portion. A rectangular insertion hole in a plan view through which the head can be inserted and a locking portion that is pulled upward against the elasticity of the elastic member and rotated 90 degrees in either the left or right direction are displaced from the insertion hole. It is composed of a receiving part to be locked.
That is, the locking portion is inserted into the head through the insertion hole portion and the insertion hole portion of the locked portion, and then the locking portion is pulled upward against the restoring force of the spring and either left or right. Rotate it 90 degrees in that direction to lock it to the receiving part. As a result, the tip of the locking portion, which is a part of the neck, is locked in the head, and the head is detachably connected.

この特許文献３に開示の連結構造によれば、頭部の挿入孔部を押し広げることもなく、係止部の引き上げ動作と回転動作のみで頭部の差し替えが容易に成し得るため、従来の課題を有効に解消し得るものである。
しかし、特許文献３に開示の連結構造であっても、係止部をスプリングの復元力に抗して引き上げると共に、その状態を維持しつつ左右方向に回転させる手間を要していたため、特に、強い力をあまり有していない女性や子供達などにあっては、容易に頭部の差し替え作業が成し得ていたとは言えない場合もあったため改良の余地を残していたものである。 According to the connection structure disclosed in Patent Document 3, the head can be easily replaced only by pulling up and rotating the locking portion without expanding the insertion hole of the head. Can effectively solve the problem of.
However, even with the connection structure disclosed in Patent Document 3, it takes time and effort to pull up the locking portion against the restoring force of the spring and to rotate it in the left-right direction while maintaining that state. For women and children who did not have much strong power, it could not be said that the head replacement work could be easily completed, so there was room for improvement.

次に、図５（ａ）で装着していた頭部１９を取り外して異なった頭部１９に交換するには、連結部材３１を構成する左右の係合片４５，４５のそれぞれの上端側をつまんで引寄せるようにして接近させる。すると、硬質合成樹脂からなる接続部４３，４３の復元力に抗して接続部４３，４３がねじり変形する。
これにより、接続部４３，４３を支点として（軸として）左右の係合爪部４９，４９同士が離間する方向に回動して変位し、係合突面部１５と係合面５１との係合（噛合）が解除される（第二状態）。
そして、連結部材３１を上方に引き抜くと共に、装着していた頭部１９を上方に引き抜く。 Next, in order to remove the head 19 attached in FIG. 5A and replace it with a different head 19, the upper end sides of the left and right engaging pieces 45 and 45 constituting the connecting member 31 are respectively. Pinch and pull them closer. Then, the connecting portions 43, 43 are twisted and deformed against the restoring force of the connecting portions 43, 43 made of the hard synthetic resin.
As a result, the left and right engaging claws 49, 49 rotate and displace in the direction in which the left and right engaging claws 49, 49 are separated from each other with the connecting portions 43, 43 as fulcrums (as an axis), and the engaging projection surface portion 15 and the engaging surface 51 are engaged with each other. The engagement (meshing) is released (second state).
Then, the connecting member 31 is pulled out upward, and the head 19 that has been attached is pulled out upward.

そして次に、交換する頭部１９を用意し、その挿入孔部２３に、頸部３を構成する棒状部７を挿し込んで、頭部１９の挿入孔部２３の外周囲の凹面２５と、頸部本体５の傾斜面（上端部）１１とを当接させる。 Next, a head 19 to be replaced is prepared, and a rod-shaped portion 7 constituting the neck portion 3 is inserted into the insertion hole portion 23 to form a concave surface 25 on the outer periphery of the insertion hole portion 23 of the head 19. The inclined surface (upper end portion) 11 of the neck body 5 is brought into contact with the inclined surface (upper end portion) 11.

そして、連結部材３１の双方の係合片４５，４５の上端側をつまんで引寄せるようにして接近させると、下端側の係合爪部４９，４９が離間して拡開状態となる（第二状態）。
その状態で、開放口２７から頭部１９内に連結部材３１を差し入れる。そして、連結部材３１の押え部３３の挿入口３５内に、頭部１９内に突出している棒状部７の上端を挿入し、予め配していた頭部１９の挿入孔部２３方向へと連結部材３１を押し込んでいく（図５（ｂ））。 Then, when the upper end sides of both the engaging pieces 45, 45 of the connecting member 31 are pinched and brought closer to each other, the engaging claws 49, 49 on the lower end side are separated and opened (the first). Two states).
In that state, the connecting member 31 is inserted into the head 19 from the opening 27. Then, the upper end of the rod-shaped portion 7 protruding into the head 19 is inserted into the insertion port 35 of the holding portion 33 of the connecting member 31 and connected in the direction of the insertion hole portion 23 of the head 19 arranged in advance. The member 31 is pushed in (FIG. 5 (b)).

このとき、連結部材３１の係合片４５は、係合爪部４９のテーパ面５３が、棒状部７の漏斗状面部１７と面接触可能に形成されているため、連結部材３１の押し込み方向（連結する方向）、すなわち、頭部１９の挿入孔部２３に向かう方向（頸部本体５に向かう方向）に連結部材３１を押し込んでいけば、漏斗状面部１７の傾斜状の面部に沿って係合爪部４９のテーパ面５３が容易に案内される。 At this time, the engaging piece 45 of the connecting member 31 is formed so that the tapered surface 53 of the engaging claw portion 49 can come into surface contact with the funnel-shaped surface portion 17 of the rod-shaped portion 7. If the connecting member 31 is pushed in the direction of connecting), that is, in the direction of the head 19 toward the insertion hole 23 (direction toward the neck body 5), the connecting member 31 is engaged along the inclined surface portion of the funnel-shaped surface portion 17. The tapered surface 53 of the joint claw portion 49 is easily guided.

そして、押え部３３の下面３３ａが、頭部１９の外皮２１に設けられている挿入孔部２３の開口周面に当接し、押え部３３によって頭部１９の外皮２１の挿入孔部２３の開口周面を押圧して頸部本体５の傾斜面（上端部）１１と挟みこむ位置で、連結部材３１の双方の係合片４５，４５の上端側をつまんで引寄せていた力を解除すると、復元力に抗して接続部４３，４３をねじり変形させていた力が解かれるため、接続部４３，４３を支点として（軸として）左右の係合爪部４９，４９同士が、棒状部７の係合部１３に係合可能な距離となるよう（それぞれの係合爪部４９間の距離が接近するよう）に回動して変位する（第一状態）。 Then, the lower surface 33a of the pressing portion 33 comes into contact with the opening peripheral surface of the insertion hole portion 23 provided in the outer skin 21 of the head portion 19, and the pressing portion 33 opens the insertion hole portion 23 of the outer skin 21 of the head portion 19. When the peripheral surface is pressed to sandwich the cervical body 5 with the inclined surface (upper end) 11, the upper ends of both engaging pieces 45 and 45 of the connecting member 31 are pinched to release the pulling force. Since the force that twisted and deformed the connecting portions 43, 43 against the restoring force is released, the left and right engaging claw portions 49, 49 (as an axis) with the connecting portions 43, 43 as fulcrums are rod-shaped portions. It is rotated and displaced so as to be a distance that can be engaged with the engaging portion 13 of No. 7 (so that the distance between the engaging claw portions 49 is close to each other) (first state).

これにより、係合爪部４９の係合面５１が棒状部７の係合突面部１５に係合（噛合）され、連結部材３１が棒状部７の任意の位置に固定されるため、頭部１９を構成する外皮２１の厚みが異なる頭部１９を連結するような要望に対しても対応することができる。
本実施形態によれば、いわゆるラチェット機構を採用しているため、連結部材３１の押し込み作業が容易になし得るが、反対に持ち上げる方向（連結を解除する方向）には係合爪部４９の係合面５１が棒状部７の係合突面部１５に係合（噛合）されて連結部材３１の不意の抜け外れを確実に阻止できる。 As a result, the engaging surface 51 of the engaging claw portion 49 is engaged (engaged) with the engaging protruding surface portion 15 of the rod-shaped portion 7, and the connecting member 31 is fixed at an arbitrary position of the rod-shaped portion 7, so that the head It is also possible to respond to a request for connecting heads 19 having different thicknesses of the outer skin 21 constituting the 19.
According to the present embodiment, since the so-called ratchet mechanism is adopted, the pushing operation of the connecting member 31 can be easily performed, but in the opposite direction, the engaging claw portion 49 is engaged in the lifting direction (disconnecting direction). The mating surface 51 is engaged (engaged) with the engaging protruding surface portion 15 of the rod-shaped portion 7, and the connecting member 31 can be reliably prevented from coming off unexpectedly.
