Description

【０００１】
【発明の属する技術分野】
本願発明は、人形玩具、ロボット玩具、動物玩具の頭体に関し、詳しくは形態が変化する可変頭体に関するものである。
【０００２】
【従来の技術】
従来、人形玩具等の形態が変化する可変頭体６１は、図５に示すように、頭部本体６２と頭部カバー６３とからなる。頭部本体６２の上部には、取付穴６５が形成されている。頭部カバー６３は、下部に取付軸６６が突設されており、当該取付軸６６を頭部本体６２の取付穴６５に摺動自在に差し込んで頭部本体６２に取り付けられている。取付軸６６の差し込む深さを変えることにより、取付カバー６３が上下して頭部本体６２の表出する部分が変わり、可変頭体６１の形態をを変化させることができる。
【０００３】
【発明が解決しようとする課題】
上記従来の可変頭体６１は、形態の変化が少なく、又取部カバー６３を上方に移動させるだけの動作で形態を変化させるので意外性が乏しく、面白みに欠けるという問題点があった。また頭部カバー６３を上部に大きく移動して形態を変化させるので、瞬間的に形態が変化せず、見ている者を驚かせることができないという問題点もあった。
【０００４】
本願発明は、上記問題点に鑑み案出したものであって、頭部本体を覆うことができ、形態の変化に意外性があって極めて面白く、さらに瞬間的に形態を変化させることができる、従来にない新規な構造の可変頭体を提供することを目的とする。
【０００５】

（イ）頭部本体と頭部本体の前部の少なくとも一部を覆うことが可能な前部カバー体とからなること。
（ロ）前部カバー体は、上前部カバーと下前部カバーとからなり、上前部カバーの下部と下前部カバーの上部を回動自在に連結する連結部を有すること。
（ハ）前記前部カバー体は、前記連結部を後方に押圧すると、前記連結部を介して、前記上前部カバーと前記下前部カバーが回動して、前記上前部カバーの下縁と前記下前部カバーの上縁が接合して前記頭部本体の前部の少なくとも一部を覆うこと。
（ニ）前記前部カバー体は、前記連結部を前方に引っ張ることにより、前記連結部を介して、前記上前部カバーと前記下前部カバーが回動し、前記上前部カバーの下縁と前記下前部カバーの上縁との間に隙間が形成され、当該隙間から前記頭部本体の少なくとも一部が表出すること。
