【発明の属する技術分野】
本発明は、こまを回して楽しむことができるこま玩具に関する。
【0002】
【従来の技術】
従来、こまの軸にギヤを取り付け、そのこまをホルダーに回転可能に保持させ、そのこまのギヤにラックを噛み合わせ、そのラックを引き抜くことでこまを回転させ、同時にホルダーから下方に落下させ、床面上でこまを回して楽しむこま玩具が知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、従来のこま玩具では、こまの構造が複雑であったり、こまに取り付けているギヤがこまの軸に対してから回りしてこまが回らないとか、ラックを引き抜く時、摩擦抵抗が大きくて引き抜きにくいとか、ホルダーに保持されたこまが傾いてうまく回らないことがあるといった問題があった。
【0004】
本発明はかかる問題点に鑑みてなされたもので、誰でもこまをうまく回して楽しむことができる簡単な構造の、安価なこま玩具を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明のこま玩具は、こまと、そのこまを回転させるために保持するハンドルと、こまに回転力を与えるためのプルとからなるものである。そして、前記こまを、円板の中心上下に軸を備えた上部材と、その上部材の下面側に前記軸に嵌合して取り付けられた下部材と、前記上部材の上面側の軸に形成した角柱部分に嵌合して取り付けられたギヤを有する構成とし、前記ハンドルを、指でつかむための取手部分と、その先端に互いに平行に形成された上支持板及び下支持板と、その上支持板及び下支持板の間の根元に直角に形成された面と、その面の両端近傍に形成されたプル支持用の突起と、前記上支持板に形成され、前記こまの上面側の軸の先端を回転可能に保持する軸支持穴と、前記下支持板に形成され、前記こまのギヤを挿入可能なギヤ挿入開口と、前記上支持板及び下支持板の先端を一定間隔に保つように連結する連結部と、前記下支持板の先端に形成され、前記こまの上部材の円板の外周近傍の上面を支持可能な突起を有する構成とし、更に、前記プルを、前記こまのギヤに噛み合うラックを備えると共に、そのラックを前記ハンドルに保持されたこまのギヤと前記ハンドルのプル支持用の突起との間に位置させ且つ前記ギヤに噛み合わせた状態で引き抜き可能な構成としている。
【0006】
本発明は上記構成により、こまをハンドルに保持させ、そのこまのギヤにプルのラックを噛み合わせ、その状態でプルを引き抜くという操作を行うことにより、こまを回転させると共にそのこまをハンドルから外し、床面、机上面等の平坦面の上に下ろして回転させることがのて、こまを簡単の操作で回して楽しく遊ぶことができる。
【0007】
ここで、前記したように、円板の中心上下に軸を備えた上部材に対してその軸を基準として下部材及びギヤを取り付けてこまを構成したことにより、各部品を正確に同心状に組み立てることができ、従ってこまの重心を正確にこまの中心軸線上に位置させることができ、良く回るこまを作ることができる。また、ギヤを軸に形成した角柱部分に嵌合する構成としたことにより、ギヤが軸に対して空回りすることがなく、ギヤからこまに回転を確実に伝達できる。更に、こまを構成する各部品は簡単な形状であるので、成形等によって容易に且つ安価に製造できる。また、本発明に使用するハンドルは、こまを保持するための上支持板及び下支持板を先端側で一定間隔に保持するよう連結部で連結したことで剛性が高くなり、こまを一定の姿勢に保つことができる。また、こまのギヤにラックを噛み合わせた時、ラックがギヤをハンドルの先端方向に押すこととなり、このため、こまは上支持板に支持された軸先端を中心として前方に傾こうとするが、下支持板先端に形成している突起が、こまの上部材の円板の外周近傍の上面を支えるので、こまの傾きが抑制される。これによってもこまを一定の姿勢に保つことができ、プルの引き抜きによってこまをスムーズに回転させることができる。更に、プルのラックをこまのギヤに噛み合わせた状態でプルを引き抜いてこまを回転させる際、そのラックの背面はハンドルに形成しているプル支持用の突起で支持されており、このため、点接触に近い状態で支持されるため、プル引き抜き時の抵抗が小さく、容易にプルを引き抜いてこまを高速で回転させることができる。
【0008】
【発明の実施の形態】
以下、図面に示す本発明の実施例により本発明を更に詳細に説明する。
図1は本発明の一実施例によるこま玩具の概略斜視図、図2はそのこま玩具を、こまを回す時の状態で示すもので、(a)は概略平面図、(b)は概略断面図、(c)は(b)のA−A矢視概略断面図である。全体を参照符号1で示すこま玩具は、こま10と、そのこま10を回転させるために保持するハンドル20と、こま10に回転力を与えるためのプル30とからなる。以下、各部品を詳細に説明する。
【0009】
こま10は、図3に示す外形のものであり、図4に分解して示すように、上部材11と、下部材12と、ギヤ13と、適当な絵柄、模様、説明文等を印刷した円形紙14等からなる。上部材11は、図5にも示すように、円板11aの中心上下に軸11b、11cを一体に形成したものであり、上側の軸11bは円板に接する部分にギヤ13を取り付けるための角柱部分11dを備えている。この角柱部分11dとして、この実施例では四角形断面のものを示しているが、三角形断面或いは五角形以上の多角形断面としてもよい。円板11aの上面には円形の平坦面11aaが形成されており、その平坦面11aaに円形紙14を貼り付けるようになっている。また、円板11aの周縁部には、好ましい意匠を形成するように適当な凹凸や模様が形成されている。周縁部に形成する凹凸や模様は任意であり、種々変更可能である。図7はいろいろな周縁部を備えた上部材の例を示すものであり、上部材11A、11B、11C、11D、11Eが示されている。
【0010】
図4において、下部材12は、上部材11の下面側に、軸11cに嵌合して取り付けられるもので、図6にも示すように、球面状の下面12aの下端中心に回転中心となる突起12bを有し、且つ内面(上面)に上部材11の軸11cを挿入させるための環状突起12cを有している。この下部材12を上部材11に取り付けるには、環状突起12cに軸11cを嵌合させると共に、両者を適当な接着剤で接合する。また、必要に応じ、下部材12の上端と上部材11の円板11aの下面との接触面を接着剤で接合するようにしてもよい。なお、この実施例では軸11c及び環状突起12cの穴を円形断面としているが、両者の回転止めを図るために、角形断面としてもよい。
【0011】
図4において、ギヤ13は中心に、上部材11の上面側の軸11bに形成した角柱部分11dに嵌合するための角形断面の貫通穴13aを備えている。このギヤ13も角柱部分11dに嵌合させると共に接着剤によって固定される。
【0012】
こま10は、上記した上部材11の上下の軸11b、11cにそれぞれ、ギヤ13、下部材12を嵌合し、接着剤で固定して組み立てられ、この構成の採用により、各部材を正確に同心状に組み立てることができる。従って、このこま10は、重心が正確にこまの中心軸線上に位置しており、良く回る。また、ギヤ13を軸11bの角柱部分11dに嵌合させたことにより、ギヤ13の回転を上部材11に確実に伝達できる。更に、こま10を構成する上部材11、下部材12、ギヤ13は簡単な形状であるので、樹脂(例えば、PP、PE、ナイロン、POM、ABS等)の成形等によって容易に且つ安価に製造できる。
【0013】
図1、図2及び図8において、ハンドル20は、樹脂(例えば、PP、PE、ナイロン、POM、ABS等)の成形等によって一体構造に作られたものである。このハンドル20は、指でつかむための取手部分21と、その先端に互いに平行に形成された上支持板22及び下支持板23と、その上支持板22及び下支持板23の間の根元に直角に形成された面24と、その面の両端近傍に形成されたプル支持用の突起25と、上支持板22に形成され、こま10の上面側の軸11bの先端を回転可能に保持する軸支持穴26と、下支持板23に形成され、こま10のギヤ14を挿入可能なギヤ挿入開口27と、上支持板22及び下支持板23の先端を一定間隔に保つように連結する連結部28と、下支持板23の先端に形成され、こま10の上部材11の円板11aの外周近傍の上面を支持可能な突起29を有している。ここで、取手部分21は全体が偏平な形をしており、その周縁に補強のためのリブを形成している。また、下支持板23に形成しているギヤ挿入開口27は、少なくとも下支持板の先端側に円弧状の縁27aを備えている。この円弧状の縁27aは、ギヤ13をギヤ挿入開口27内の所定位置に挿入した時、そのギヤ13との間に微小な間隙が形成されるように設けられており、ハンドル20に保持させたこま10の軸線がハンドル20の先端側に傾いたとき、その縁27aでギヤ13の周面を支持することができる。
【0014】
図1、図2において、プル30は、ギヤ13に噛み合うラック31とつまみ32を備えたものであり、これも、樹脂(例えば、PP、PE、ナイロン、POM、ABS等)の成形等によって一体構造に作られる。ここで、ラック31の厚さ(歯先から背面までの距離)は、図2に示すように、ハンドル20にこま10を保持させた状態で、そのこま10のギヤ13とハンドル20のプル支持用の突起25との間にラック31を位置させ、そのラック31をギヤ13に噛み合わせた時、そのラック31の背面にプル支持用の突起25が軽く接触し、従って、ラック31をギヤ13に噛み合わせた状態でそのラック31をB矢印方向に引き抜くことができるように定められている。
【0015】
このこま玩具で遊ぶ時は、図2に示すように、こま10の上面側の軸11bをハンドル20の下支持板23側から上支持板22の軸支持穴26に挿入し、且つこま10の円板11aを下支持板23に押し付け、これによってギア13を上下支持板22、23の間に位置させ、その前後にプル30のラック31を上下支持板22、23の間に差し込んでギア13にかみ合わせる。このギア13とラック31のかみ合いにより、ハンドル20を、下支持板23が下側となる状態で水平としても、こま10がハンドル20から抜け落ちることはない。次に、この状態でプル30を矢印B方向に引き抜く。これにより、こま10が回転させられ、ハンドル20から下方に抜けて床面、机上面等の上に落ち、そこで回転することとなる。
【0016】
ここで、図2(b)に示すように、ハンドル20の上支持板22と下支持板23にこま10を保持させ且つプル30のラック31にかみ合わせ、そのプル30を引き抜いてこま10を回転させる際、そのラック31がこま10に横方向の力を作用させ、こま10は軸11bの軸支持穴26に挿入している部分を支点として矢印Cで示す方向に傾く傾向がある。このため、こま10の円板11aが下支持板23を上に押し上げようとするが、下支持板23は先端が連結部28で上支持板22に連結され、剛性が高くなっているので、たわむことはなく、安定してこま10を一定の姿勢に保つことができる。また、こま10が矢印C方向に傾こうとした時、下支持板先端に形成している突起29が、こま10の円板11aの外周近傍の上面を支持するので、こま10の傾きが抑制され、これによってもこま10を安定して一定の姿勢に保つことができる。このため、こま10はハンドル20に保持された状態で安定して回転できる。また、プル30のラック31をこま10のギヤ13に噛み合わせた状態で引き抜いてこま10を回転させる際、そのラック31の背面はハンドル20に形成しているプル支持用の突起25で支持されており、このため、点接触に近い状態でラック31が支持されるため、プル引き抜き時の抵抗が小さく、容易にプル30を引き抜いてこま10を高速で回転させることができる。かくして、容易にこま10を高速で回転させ、床面等に下ろして回転させ、遊ぶことができる。
【0017】
【発明の効果】
以上のように、本発明のこま玩具は、こまをハンドルに保持させ、プルを引き抜くという簡単な操作で、こまを安定して高速回転させ、床面、机上面等の平坦な面の上に下ろすことができ、こまを回して楽しく遊ぶことができるという効果を有している。また、こま玩具を構成するハンドル、プル、及びこまを構成する上部材、下部材、ギヤはいずれも比較的簡単な形状で樹脂の成形で容易に製造できるので、安価であるという効果も有している。

BACKGROUND OF THE INVENTION
The present invention relates to a top toy that can be enjoyed by turning the top.
[0002]
[Prior art]
Conventionally, a gear is attached to the top shaft, the top is rotatably held in the holder, the rack is engaged with the top gear, the top is rotated by pulling out the rack, and at the same time, the top is dropped downward from the holder, There are known top toys that you can enjoy by turning the top on the floor.
[0003]
[Problems to be solved by the invention]
However, with the conventional top toy, the top structure is complicated, the gear attached to the top does not rotate around the top shaft, or the top does not turn. There were problems that it was difficult to pull out or that the top held by the holder could not be rotated properly.
[0004]
The present invention has been made in view of such problems, and an object of the present invention is to provide an inexpensive top toy having a simple structure that can be enjoyed by anyone turning around the top.
[0005]
[Means for Solving the Problems]
The top toy of the present invention comprises a top, a handle for holding the top, and a pull for applying a rotational force to the top. Then, the top is attached to an upper member having a shaft above and below the center of the disk, a lower member fitted and attached to the lower surface side of the upper member, and an upper surface side shaft of the upper member. A structure having a gear fitted and attached to the formed prismatic part, a handle part for grasping the handle with a finger, an upper support plate and a lower support plate formed parallel to each other at the tip, and A surface formed perpendicular to the base between the upper support plate and the lower support plate, a protrusion for pull support formed near both ends of the surface, and a shaft formed on the upper support plate, A shaft support hole that rotatably holds the tip, a gear insertion opening that is formed in the lower support plate and into which the top gear can be inserted, and the tips of the upper support plate and the lower support plate are kept at regular intervals. A connecting portion to be connected, and formed at the tip of the lower support plate, And a protrusion that can support the upper surface of the member in the vicinity of the outer periphery of the disk, and further, the pull includes a rack that meshes with the top gear, and the top gear that is held by the handle and the top gear. It is configured to be able to be pulled out in a state where it is positioned between the pull supporting protrusion of the handle and meshed with the gear.
[0006]
With the above configuration, the present invention holds the top on the handle, engages the rack of the pull with the top gear, and pulls the pull in this state, thereby rotating the top and removing the top from the handle. Since it can be lowered and rotated on a flat surface such as a floor surface or a desk surface, the top can be rotated with a simple operation to have fun.
[0007]
Here, as described above, the upper member provided with a shaft above and below the center of the disk is configured by attaching a lower member and a gear with the shaft as a reference, so that each component is accurately concentric. Can be assembled, so the center of gravity of the top can be accurately positioned on the center axis of the top, and a top that turns well can be made. Further, by adopting a configuration in which the gear is fitted to the prism portion formed on the shaft, the gear does not idle with respect to the shaft, and rotation can be reliably transmitted from the gear to the top. Furthermore, since each component constituting the top has a simple shape, it can be easily and inexpensively manufactured by molding or the like. In addition, the handle used in the present invention has a high rigidity by connecting the top support plate and the lower support plate for holding the top at a fixed interval on the tip side so that the top is fixed, and the top is fixed. Can be kept in. In addition, when the rack is engaged with the top gear, the rack pushes the gear toward the front end of the handle. For this reason, the top tends to tilt forward about the shaft tip supported by the upper support plate. Since the protrusion formed at the tip of the lower support plate supports the upper surface of the upper member in the vicinity of the outer periphery of the disk, the inclination of the top is suppressed. As a result, the top can be kept in a constant posture, and the top can be smoothly rotated by pulling out the pull. Furthermore, when the pull rack is engaged with the top gear and the top is pulled out to rotate the top, the back of the rack is supported by a pull support protrusion formed on the handle. Since it is supported in a state close to point contact, resistance at the time of pulling out the pull is small, and the pull can be easily pulled out to rotate the top at high speed.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to embodiments of the present invention shown in the drawings.
FIG. 1 is a schematic perspective view of a top toy according to an embodiment of the present invention, FIG. 2 shows the top toy in a state when the top is turned, (a) is a schematic plan view, and (b) is a schematic cross section. FIG. 2C is a schematic cross-sectional view taken along the line AA in FIG. A top toy generally indicated by reference numeral 1 includes a top 10, a handle 20 that is held to rotate the top 10, and a pull 30 that applies a rotational force to the top 10. Hereinafter, each component will be described in detail.
[0009]
The top 10 has the outer shape shown in FIG. 3, and as shown in an exploded view in FIG. 4, the upper member 11, the lower member 12, the gear 13, and an appropriate pattern, pattern, description, etc. are printed. It consists of circular paper 14 or the like. As shown in FIG. 5, the upper member 11 is formed by integrally forming shafts 11 b and 11 c on the upper and lower sides of the center of the disk 11 a, and the upper shaft 11 b is used for attaching the gear 13 to a portion in contact with the disk. A prismatic portion 11d is provided. In this embodiment, the prism portion 11d has a quadrangular cross section, but it may be a triangular cross section or a polygonal cross section having a pentagon or more. A circular flat surface 11aa is formed on the upper surface of the disk 11a, and a circular paper 14 is attached to the flat surface 11aa. Further, appropriate irregularities and patterns are formed on the peripheral edge of the disk 11a so as to form a preferable design. The irregularities and patterns formed on the peripheral edge are arbitrary and can be variously changed. FIG. 7 shows examples of upper members having various peripheral portions, and upper members 11A, 11B, 11C, 11D, and 11E are shown.
[0010]
In FIG. 4, the lower member 12 is attached to the lower surface side of the upper member 11 by being fitted to the shaft 11 c, and as shown in FIG. 6, the lower member 12 is the center of rotation at the lower end center of the spherical lower surface 12 a. It has a projection 12b and an annular projection 12c for inserting the shaft 11c of the upper member 11 on the inner surface (upper surface). In order to attach the lower member 12 to the upper member 11, the shaft 11c is fitted to the annular protrusion 12c, and both are joined with an appropriate adhesive. Moreover, you may make it join the contact surface of the upper end of the lower member 12, and the lower surface of the disk 11a of the upper member 11 with an adhesive agent as needed. In this embodiment, the shaft 11c and the hole of the annular projection 12c have a circular cross section, but may have a square cross section in order to prevent rotation of both.
[0011]
In FIG. 4, the gear 13 is provided with a through hole 13 a having a square cross section for fitting into a prism portion 11 d formed on the shaft 11 b on the upper surface side of the upper member 11 at the center. The gear 13 is also fitted to the prism portion 11d and fixed with an adhesive.
[0012]
The top 10 is assembled by fitting the gear 13 and the lower member 12 to the upper and lower shafts 11b and 11c of the upper member 11 and fixing them with an adhesive, respectively. Can be assembled concentrically. Accordingly, the top 10 rotates well because its center of gravity is accurately located on the center axis of the top. In addition, the rotation of the gear 13 can be reliably transmitted to the upper member 11 by fitting the gear 13 to the prism portion 11d of the shaft 11b. Furthermore, since the upper member 11, the lower member 12, and the gear 13 constituting the top 10 have simple shapes, they are easily and inexpensively manufactured by molding a resin (for example, PP, PE, nylon, POM, ABS, etc.). it can.
[0013]
1, 2, and 8, the handle 20 is formed into an integral structure by molding a resin (for example, PP, PE, nylon, POM, ABS, or the like). The handle 20 has a handle portion 21 for grasping with a finger, an upper support plate 22 and a lower support plate 23 formed parallel to each other at the tip thereof, and a root between the upper support plate 22 and the lower support plate 23. A surface 24 formed at a right angle, a protrusion 25 for pull support formed in the vicinity of both ends of the surface, and an upper support plate 22 are formed to rotatably hold the tip of the shaft 11b on the upper surface side of the top 10. A shaft support hole 26, a gear insertion opening 27 formed in the lower support plate 23 and into which the gear 14 of the top 10 can be inserted, and a connection for connecting the tips of the upper support plate 22 and the lower support plate 23 so as to maintain a constant interval. And a protrusion 29 formed on the tip of the lower support plate 23 and capable of supporting the upper surface of the upper member 11 of the top 10 near the outer periphery of the disk 11a. Here, the handle portion 21 has a flat shape as a whole, and a rib for reinforcement is formed on the periphery thereof. Further, the gear insertion opening 27 formed in the lower support plate 23 is provided with an arcuate edge 27a at least on the distal end side of the lower support plate. The arc-shaped edge 27 a is provided so that a minute gap is formed between the gear 13 and the gear 13 when the gear 13 is inserted into a predetermined position in the gear insertion opening 27. When the axis of the egg 10 is tilted toward the distal end side of the handle 20, the peripheral surface of the gear 13 can be supported by the edge 27a.
[0014]
1 and 2, the pull 30 is provided with a rack 31 and a knob 32 that mesh with the gear 13, and this is also integrated by molding a resin (for example, PP, PE, nylon, POM, ABS, etc.). Made to structure. Here, the thickness of the rack 31 (distance from the tooth tip to the back surface) is determined by pulling the gear 13 of the top 10 and the handle 20 in a state where the top 10 is held by the handle 20 as shown in FIG. When the rack 31 is placed between the rack 31 and the gear 31, the pull-supporting protrusion 25 comes into light contact with the back surface of the rack 31. The rack 31 is determined so that it can be pulled out in the direction of the arrow B in a state of being engaged with each other.
[0015]
When playing with this top toy, as shown in FIG. 2, the shaft 11 b on the top surface of the top 10 is inserted into the shaft support hole 26 of the top support plate 22 from the lower support plate 23 side of the handle 20, and The disc 11 a is pressed against the lower support plate 23, whereby the gear 13 is positioned between the upper and lower support plates 22, 23, and the rack 31 of the pull 30 is inserted between the upper and lower support plates 22, 23 before and after the gear 13. Engage with. Due to the engagement between the gear 13 and the rack 31, the top 10 does not fall out of the handle 20 even when the handle 20 is horizontal with the lower support plate 23 on the lower side. Next, the pull 30 is pulled out in the arrow B direction in this state. As a result, the top 10 is rotated, falls downward from the handle 20, falls onto the floor surface, the desk surface, etc., and rotates there.
[0016]
Here, as shown in FIG. 2B, the top 10 is held by the upper support plate 22 and the lower support plate 23 of the handle 20 and engaged with the rack 31 of the pull 30, and the pull 30 is pulled out to rotate the top 10. When this is done, the rack 31 applies a lateral force to the top 10, and the top 10 tends to tilt in the direction indicated by the arrow C with the portion inserted into the shaft support hole 26 of the shaft 11b as a fulcrum. For this reason, the disc 11a of the top 10 tries to push up the lower support plate 23, but the lower support plate 23 is connected to the upper support plate 22 at the tip by the connecting portion 28, and has high rigidity. There is no deflection, and the top 10 can be stably maintained in a certain posture. Further, when the top 10 is inclined in the direction of arrow C, the protrusion 29 formed at the tip of the lower support plate supports the upper surface of the top 10 near the outer periphery of the disc 11a, so that the inclination of the top 10 is suppressed. Accordingly, the top 10 can be kept in a stable and constant posture. For this reason, the top 10 can rotate stably while being held by the handle 20. When the rack 31 of the pull 30 is pulled out in a state where the rack 31 is engaged with the gear 13 of the top 10 and the top 10 is rotated, the back surface of the rack 31 is supported by the pull supporting projection 25 formed on the handle 20. For this reason, since the rack 31 is supported in a state close to point contact, the resistance at the time of pulling out the pull is small, and the pull 30 can be pulled out easily and the top 10 can be rotated at high speed. Thus, the top 10 can be easily rotated at a high speed, lowered onto the floor surface, and rotated to play.

【The invention's effect】
As described above, the top toy of the present invention allows the top to be stably rotated at a high speed by a simple operation of holding the top on the handle and pulling out the pull on a flat surface such as a floor surface or a desk surface. It has the effect that it can be taken down and can be enjoyed by turning the top. In addition, since the handle, the pull, and the upper member, the lower member, and the gear that constitute the top can be easily manufactured by resin molding with a relatively simple shape, there is also an effect that it is inexpensive. ing.
