Abstract

<P>PROBLEM TO BE SOLVED: To prevent an assembling top from injuring a person with a spindle, and also damaging tatami mats (thick straw mats that cover the floor) or the like even when the top is rotated on the tatami mats or a carpet. <P>SOLUTION: The assembling top includes: a right circular conic trapezoidal body 11; the spindle 13 to be the rotary axis of the body 11; and a balance ring 15 for preventing the eccentric rotation of the body 11 to be rotated with the spindle 13 as a center. The body 11 includes a hole 12 in the center of axle at the side of a top surface 11a, where the spindle 13 is inserted so as to be removable. A ring shape recession 14 is also arranged in a peripheral edge part at the side of a bottom surface 11b, where the balance ring 15 is removably fitted. The spindle 13 has a spherical surface at the tip end. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
この発明は、組立てと分解が可能な組立てこまに関するものである。
【0002】
【従来の技術】
従来の組立てこまKは、図5及び図6に示すように、直円錐台形の胴1の頂面1a側の軸心部に設けた穴2に心棒3を挿入し、胴1の底面1b側の周縁部に設けた環状凹部4にバランスリング5を嵌着することによって組立てることができる。組み立てたこまKは、使用しなければ、必要に応じ分解することができる。
【0003】
図7は、組み立てたこまKを回す場合の紐6の巻き付け要領を示したものである。
【0004】
【発明が解決しようとする課題】
従来の組立てこまKは、上述のように、組立て分解ができる構成となっているので、これを回す子供たちにとっては、組立て分解の楽しさがあり、胴、心棒、バランスリングの各構成部材の機能(働き)を改めて考えさせる教材にもなっている。
【0005】
しかし、従来のこまKは、図5〜7に示すように、心棒3の先端が円錐状に尖った形状になっているので、畳、じゅうたん、板床などの上で回すと、これらのものを傷付ける。
【0006】
それだけでなく、こまKを投げ出して回すときに、心棒3の先端が誤って人に当ってその身体を傷付けることがあり、危険である。
【0007】

【0008】
【課題を解決するための手段】
この発明が提供する組立てこまは、直円錐台形の胴と、胴の回転軸となる心棒と、心棒を中心として回転する胴の偏心回転を防止するバランスリングとよりなり、前記胴は、その頂面側の軸心部に前記心棒を着脱可能に挿入する穴を有し、その底面側の周縁部に前記バランスリングを着脱可能に嵌着する環状凹部を有し、前記心棒は、その先端が球面状となっているものである。
【0009】
【発明の実施の形態】
以下、この発明の実施の形態を実施例によって図面を参照しながら説明する。
【0010】
図1は、実施例の組立てこまの斜視図、図2は図1の縦断面拡大図、図3及び図4は実施例の組立てこまの組立て要領を示す斜視図である。
【0011】
図において、11は直円錐台形の胴、13は胴11の回転軸となる心棒、15は心棒13を中心として回転する胴11の偏心回転を防止するバランスリングである。
【0012】
胴11は、その頂面11a側の軸心部に前記心棒13を着脱可能に挿入する穴12を有しており、その底面11B側の周縁部に前記バランスリング15を着脱可能に嵌着する環状凹部を有している。
【0013】
心棒13の先端は球面となっている。実施例の組立てこまKは、心棒13の先端部が球面となっている点で、従来の組立てこまK(図5,6)と異なっている。
【0014】
実施例の組立てこまKは、次の要領で組み立てることができる。
【0015】
すなわち、図3に示すように、直円錐台形の胴11の帳面11a側の軸心部に設けた穴12に心棒13を挿入する。
【0016】
ついで、図4に示すように、胴11の底面11b側の周縁部に設けた環状凹部14にバランスリング15を嵌着する。
【0017】
一旦、組み立てたこまKは、心棒13とバランスリング15を胴11から取り外すことによって分解できる。
【0018】
実施例の組立てこまKは、上述のように、胴11と心棒13とバランスリング15の3つの構成部材でできていて、組立て分解が可能になっているので、これを回す人、特に子供達に組立て分解の楽しさを与えるだけでなく、各構成部材の機能をあらためて考える機会を与えることができる。

【0020】
なお、上記実施例では、心棒13の先端を球面としたが、これに近い球面状とすることもできる。楕円球面としてもよい。
【0021】
【発明の効果】
以上説明したように、この発明の組立てこまは、胴、心棒、バランスリングの3つの構成部材で構成し、組立てと分解ができるようにしたので、次の(1)〜(4)に記載の効果を奏する。
【0022】
(1)こまを回す人に、その組立てと分解の操作を楽しむ機会を与えることができる。
【0023】
(2)こまを回す人に、その組立てと分解の操作の過程で構成部材の機能をあらためて考える機会を与えることができる。
【0024】
(3)こまを回す人が誤ってこれを人にぶつけることがあっても、心棒形状が原因で、その人を傷付けるおそれがなくなる。
【0025】
(4)畳、じゅうたん、板床などで回しても、これらのものを傷付けない。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an assembling frame that can be assembled and disassembled.
[0002]
[Prior art]
As shown in FIGS. 5 and 6, a conventional assembling frame K has a mandrel 3 inserted into a hole 2 provided in a shaft portion on the top surface 1a side of a frustoconical cylinder 1, and a bottom 1b side of the cylinder 1. Can be assembled by fitting the balance ring 5 into the annular concave portion 4 provided in the peripheral portion of the rim. If not assembled, the assembled top K can be disassembled as needed.
[0003]
FIG. 7 shows how to wind the string 6 when the assembled frame K is turned.
[0004]
[Problems to be solved by the invention]
As described above, the conventional assembling frame K has a structure that can be assembled and disassembled, so that children who turn this have a pleasure of assembling and disassembling. It is also a teaching material that reminds you of the function (work).
[0005]
However, as shown in FIGS. 5 to 7, the conventional top K has a tip of the mandrel 3 in a conical pointed shape. Hurt.
[0006]
