Abstract

PROBLEM TO BE SOLVED: To provide a flight rubber balloon in which no mouth hole member is detached when a strong force is imparted thereto.SOLUTION: A flight rubber balloon includes: a rubber balloon body 2; an upper body 20 which has an opening provided in both upper and lower sides, which has a first engaging salient 24 projectingly provided outward on a peripheral side wall, and which has a fall-off prevention projection 23 projectingly provided outward on the upper side from the first engaging salient on the peripheral side wall; and a bottom body 30 which has an opening provided in both upper and lower sides, and which has a second engaging salient 34 projectingly provided inward on the peripheral side wall. The peripheral side wall 35 of the bottom body is externally fitted to the peripheral side wall 25 of the upper body. By engagement of the first engaging salient 24 with the second engaging salient 34, the upper body and the bottom body are integrally fitted to each other. The mouth part 2a of the rubber balloon body is housed inside an acceptance space 26 below the fall-off prevention projection between the peripheral side wall of the upper body and that of the bottom body. As a gap between the fall-off prevention projection 23 and the peripheral side wall 35 of the bottom body is smaller than the outer diameter of the mouth part 2a, it prevents the mouth part 2a from falling off.

Description

本発明は、風船内に口部から空気を注入して膨らませ、この注入した空気の噴出力によって空中に飛行させる飛行ゴム風船に関する。   The present invention relates to a flying rubber balloon that is inflated by injecting air from a mouth portion into a balloon and flying in the air by a jet output of the injected air.

なお、本明細書及び特許請求の範囲において、「ゴム風船」の語は、ゴムからなる風船はもちろんのこと、ゴム弾性を有する素材からなる風船をも含む意味で用いている。   In the present specification and claims, the term “rubber balloon” is used to include not only balloons made of rubber but also balloons made of a material having rubber elasticity.

上記飛行ゴム風船としては、従来より、上壁及び下壁に開口部が設けられた略円柱形状の中空部材(吹き口部材)の周側壁に、ゴム風船の口部を外嵌状態に嵌着したものが公知である(特許文献1〜3参照)。ゴム風船内に口部から空気を注入して膨らませた後、空中に手放すと下壁の開口部より空気が外に一気に噴出し、この噴出力が推進力となってゴム風船が略垂直方向に上昇していくのであるが、ゴム風船内に充填された空気が上壁開口部から下壁開口部に抜けていく際にその少なくとも一部が中空部材の中空空間内を還流することによってピーというような高い吹鳴音を発生し、この吹鳴し状態で空気中を飛行するものである。   Conventionally, as for the above-mentioned flying rubber balloon, the mouth of the rubber balloon is fitted in an externally fitted state on the peripheral side wall of a substantially cylindrical hollow member (blow-off member) having openings on the upper and lower walls. Is known (see Patent Documents 1 to 3). After inflating by injecting air from the mouth into the rubber balloon, letting it go into the air, air blows out from the opening of the lower wall all at once, and this jet output becomes the driving force to make the rubber balloon almost vertical Although it rises, when the air filled in the rubber balloon flows out from the upper wall opening to the lower wall opening, at least a part of it recirculates in the hollow space of the hollow member, which is called pee Such a high sounding sound is generated, and the air is blown in the air in this sounding state.

このように高い吹鳴音を発生しながら空中を飛行するので、目立つ上に興趣性にも優れるものであり、一般的な玩具として用いられており、また近年では例えばプロ野球やサッカー等のスタンド等において観客が自身の好きなチームを応援するためにこの飛行ゴム風船を一斉に空中に飛行させてその雰囲気を一気に盛り上げる、というような形態で使用されることも多くなってきている。   Because it flies in the air while generating such a high sounding sound, it is conspicuous and excellent in interest, and is used as a general toy. In recent years, for example, a stand for professional baseball, soccer, etc. In order to support their favorite team, the crowd is often used in such a way that the flying rubber balloons fly all at once in the air and raise the atmosphere at once.

ところで、上記従来の飛行ゴム風船において、中空部材に対する風船の取り付けは、略円柱形状の中空部材の周側壁にゴム風船の口部を外嵌状態に嵌着することにより行われている。即ち、従来の飛行ゴム風船では、中空部材の周側壁に突設された2条の互いに平行な環状突起の間の周溝内に、ゴム風船の口部が外嵌状態に嵌着されることによって、ゴム風船と中空部材とが互いに連結されている。   By the way, in the above conventional flying rubber balloon, the balloon is attached to the hollow member by fitting the mouth of the rubber balloon in an externally fitted state on the peripheral side wall of the substantially cylindrical hollow member. That is, in the conventional flying rubber balloon, the mouth portion of the rubber balloon is fitted in a circumferential groove between two parallel annular protrusions protruding on the peripheral side wall of the hollow member. Thus, the rubber balloon and the hollow member are connected to each other.

このような構造でゴム風船と中空部材とが連結されているから、通常の使用状態では中空部材がゴム風船から離脱することはない。   Since the rubber balloon and the hollow member are connected with such a structure, the hollow member does not come off from the rubber balloon in a normal use state.

一方、最近、玩具は、小さな子供が誤飲できないような大きさのものであっても、この玩具が、小さな部品を一体化して構成されている場合には、この小さな部品が離脱したときに誤飲する可能性のある大きさである場合には、玩具に強い力(70N)が加わった場合でも小さな部品が離脱しないように強く連結一体化されていることが求められている(平成24年10月3日発行の改定玩具安全基準書ST−2012)。   On the other hand, recently, even if the toy is of a size that cannot be swallowed by a small child, if this toy is constructed by integrating small parts, In the case of a size that may cause accidental ingestion, it is required to be strongly connected and integrated so that even if a strong force (70 N) is applied to the toy, small parts do not come off (2012). Revised Toy Safety Standards ST-2012 issued on October 3, 2000).

しかるに、上記従来の飛行ゴム風船では、中空部材の周側壁の周溝内にゴム風船の口部が外嵌された連結構造であるから、中空部材を離脱させる方向に強い力(70N)が加わると、中空部材(吹き口部材)が風船から離脱することが懸念される。   However, since the conventional flying rubber balloon has a connection structure in which the mouth portion of the rubber balloon is externally fitted in the circumferential groove of the peripheral side wall of the hollow member, a strong force (70 N) is applied in the direction of releasing the hollow member. Then, there is a concern that the hollow member (blowing member) is detached from the balloon.

本発明は、かかる技術的背景に鑑みてなされたものであって、強い力が加わっても中空部材(吹き口部材)が離脱することのない飛行ゴム風船を提供することを目的とする。   The present invention has been made in view of such technical background, and an object of the present invention is to provide a flying rubber balloon in which a hollow member (blow-off member) does not come off even when a strong force is applied.

前記目的を達成するために、本発明は以下の手段を提供する。   In order to achieve the above object, the present invention provides the following means.

When the upper body is viewed from above, the pull-out preventing projection and the first locking projection are arranged so as not to overlap,
2. The flying rubber balloon according to claim 1, wherein the second locking convex portion is an annular convex ridge portion extending along the circumferential direction on the inner surface of the peripheral side wall of the bottom body.

[5]前記底部体の周側壁は、該周側壁における上端と下端との中間位置から上端までの内径が、該中間位置から下端までの内径よりも大きく設定された拡径壁部を備え、前記上部体の周側壁と前記底部体の拡径壁部との間における前記抜脱抑止用突起部より下方に受容空間が形成されている前項1〜4のいずれか1項に記載の飛行ゴム風船。   [5] The peripheral side wall of the bottom body includes an enlarged wall portion in which an inner diameter from an intermediate position between the upper end and the lower end of the peripheral side wall to an upper end is set larger than an inner diameter from the intermediate position to the lower end, 5. The flying rubber according to any one of the preceding items 1 to 4, wherein a receiving space is formed below the protrusion for preventing removal between the peripheral side wall of the upper body and the enlarged wall portion of the bottom body. balloon.

[1]の発明では、上部体の周側壁に底部体の周側壁が外嵌状態に配置され、上部体の第1係止用凸部と底部体の第2係止用凸部とが係合されているので、上部体と底部体とが嵌合一体化された吹き口部材(中空部材)が構成される。   In the invention of [1], the peripheral side wall of the bottom body is disposed in an externally fitted state on the peripheral side wall of the upper body, and the first locking convex portion of the upper body and the second locking convex portion of the bottom body are engaged. Since they are combined, a blower member (hollow member) in which the upper body and the bottom body are fitted and integrated is configured.

また、上部体の周側壁と底部体の周側壁との間における抜脱抑止用突起部より下方に形成された受容空間内にゴム風船本体の口部が収容され、かつ上部体の抜脱抑止用突起部と底部体の周側壁との隙間の間隔がゴム風船本体の口部の外径よりも小さいので、強い力が加わってもゴム風船本体の口部が抜脱しない。従って、強い力が加わっても吹き口部材(上部体と底部体の嵌合一体化物)がゴム風船本体から離脱することがない。   In addition, the mouth of the rubber balloon body is housed in a receiving space formed below the protrusion for preventing removal between the peripheral side wall of the upper body and the peripheral side wall of the bottom body, and the upper body is prevented from being removed. Since the gap between the protruding portion for use and the peripheral side wall of the bottom body is smaller than the outer diameter of the mouth portion of the rubber balloon body, the mouth portion of the rubber balloon body does not pull out even if a strong force is applied. Therefore, even if a strong force is applied, the blower member (a fitting integrated body of the upper body and the bottom body) does not separate from the rubber balloon body.

ゴム風船本体内に空気を注入して膨らませた後、空中に手放すと、吹き口部材の開口部より空気が外に噴出し、この噴出力が推進力となってゴム風船が例えば略垂直方向に上昇していく。この時、風船本体内に充填された空気が吹き口部材内を抜けていく際にその少なくとも一部が吹き口部材の中空空間内を還流するのでピーというような高い吹鳴音を発生しながら空中を飛行する。   After inflating the air balloon body by inflating it and letting it go into the air, the air blows out from the opening of the air outlet member. It rises. At this time, when the air filled in the balloon body escapes through the blower member, at least a part of it recirculates in the hollow space of the blower member, so a high whistling sound such as a beep is generated in the air. To fly.

[2]の発明では、抜脱抑止用突起部は、上部体の周側壁の外面に周方向に沿って延設された環状の突条部であるから、ゴム風船本体の口部を抜脱抑止用突起部を超えて下方の受容空間内に装着する(収容せしめる)作業を非常に容易化できて(装着作業をスムーズに行うことができて)、生産性が向上する。   In the invention of [2], the protrusion for pulling out prevention is an annular ridge extending along the circumferential direction on the outer surface of the peripheral side wall of the upper body. The work of mounting (accommodating) in the receiving space below the depressing protrusion can be greatly facilitated (the mounting work can be performed smoothly), and productivity is improved.

[3]の発明では、第1係止用凸部は、上部体の周側壁の外面に周方向に沿って延設された環状の凸条部であり、第2係止用凸部は、底部体の周側壁の内面に周方向に沿って延設された環状の凸条部である構成であり、このような環状の第1係止用凸条部と環状の第2係止用凸条部とが係合されることにより上部体と底部体とが嵌合一体化されているので、上部体と底部体との連結強度をより高めることができる。   In the invention of [3], the first locking projection is an annular ridge extending along the circumferential direction on the outer surface of the peripheral side wall of the upper body, and the second locking projection is It is the structure which is the cyclic | annular convex ridge part extended along the circumferential direction on the inner surface of the surrounding side wall of a bottom part body, Such a cyclic | annular 1st locking convex part and a cyclic | annular 2nd locking convex Since the upper body and the bottom body are fitted and integrated by engaging the strip, the connection strength between the upper body and the bottom body can be further increased.

[4]の発明では、抜脱抑止用突起部は、上部体の周側壁の外面に周方向に沿って互いに離間して設けられた複数個の突起部からなり、第1係止用凸部は、上部体の周側壁の外面に周方向に沿って互いに離間して設けられた複数個の凸部からなり、上部体を上面視したときに(上面側から見たときに)抜脱抑止用突起部と第1係止用凸部とが重なり合わないように配置されているから(図10参照)、インジェクション成形等により上部体の成形を行った後に成形型(分割型)を外して上部体を取り出す作業をスムーズに行うことができて、生産性を向上できる。   In the invention of [4], the protrusion for preventing removal includes a plurality of protrusions provided on the outer surface of the peripheral side wall of the upper body so as to be spaced apart from each other along the circumferential direction. Consists of a plurality of protrusions provided on the outer surface of the peripheral side wall of the upper body so as to be spaced apart from each other along the circumferential direction, and is prevented from being pulled out when the upper body is viewed from the top (when viewed from the top). Since the projection for projection and the first locking projection are arranged so as not to overlap (see FIG. 10), the molding die (split die) is removed after molding the upper body by injection molding or the like. The work of taking out the upper body can be performed smoothly, and productivity can be improved.

また、第2係止用凸部は、底部体の周側壁の内面に周方向に沿って延設された「環状の」凸条部である構成であるから、上部体では複数個の第1係止用凸部が周方向に沿って互いに離間して配置された構成であるにもかかわらず、上部体と底部体との周方向の相対配置関係がどうあろうとも、常に上部体の複数個の第1係止用凸部と底部体の環状の第2係止用凸条部とが係合される。従って、生産性を向上できるし、上部体と底部体との連結強度をより高めることができる。   In addition, since the second locking convex portion is a configuration that is an “annular” convex strip portion extending along the circumferential direction on the inner surface of the peripheral side wall of the bottom body, a plurality of first protrusions are formed in the upper body. Regardless of the configuration in which the locking projections are spaced apart from each other along the circumferential direction, the upper body and the bottom body always have a plurality of upper bodies, regardless of the relative arrangement relationship in the circumferential direction. The first locking projections and the annular second locking projections of the bottom body are engaged. Therefore, productivity can be improved and the connection strength between the upper body and the bottom body can be further increased.

[5]の発明では、底部体の周側壁は、該周側壁における上端と下端との中間位置から上端までの内径が、該中間位置から下端までの内径よりも大きく設定された拡径壁部を備え、上部体の周側壁と底部体の拡径壁部との間における抜脱抑止用突起部より下方に受容空間が形成されているから、拡径壁部の存在により受容空間を形成できると共に、底部体の周側壁に拡径壁部より径小の部分が存在するので、その分材料コストを低減することができる。   In the invention of [5], the peripheral wall of the bottom body has an enlarged wall portion in which an inner diameter from an intermediate position between the upper end and the lower end of the peripheral side wall to an upper end is set larger than an inner diameter from the intermediate position to the lower end. And the receiving space is formed below the protrusion for preventing removal between the peripheral side wall of the upper body and the enlarged wall portion of the bottom body, so that the receiving space can be formed by the presence of the enlarged wall portion. At the same time, since a portion having a smaller diameter than the enlarged wall portion exists on the peripheral side wall of the bottom body, the material cost can be reduced accordingly.

前記底部体30の周側壁35は、該周側壁35における上端と下端との中間位置(途中位置)から上端までの内径が、該中間位置(途中位置)から下端までの内径よりも大きく設定された拡径壁部33を備えている(図3、4参照)。   In the peripheral side wall 35 of the bottom body 30, the inner diameter from the intermediate position (intermediate position) between the upper end and the lower end of the peripheral side wall 35 to the upper end is set larger than the inner diameter from the intermediate position (intermediate position) to the lower end. An enlarged wall portion 33 is provided (see FIGS. 3 and 4).

しかして、前記上部体20の周側壁25における抜脱抑止用突起部23より下の位置に、前記ゴム風船本体2の口部2aを上壁21側から外嵌状態に嵌着した後、前記上部体20と前記底部体30とをそれぞれの全開口側を向き合わせて上部体20の周側壁25に底部体30の周側壁35を外嵌状態に配置し、更に上部体20を底部体30側に押し込めば、上部体20の第1係止用凸条部24が底部体30の第2係止用凸条部34より下壁31側に押し込まれて、第1係止用凸条部24が第2係止用凸条部34に係合される(図2参照)ので、上部体20と底部体30とが嵌合一体化され、こうして飛行ゴム風船1が得られる。なお、嵌合一体化された上部体20と底部体30とで、略円柱形状の中空の吹き口部材3が構成され、前記吹き口部材3の上壁21の中央部に開口部22が形成され、前記吹き口部材3の下壁31の中央部に開口部32が形成されている(図2参照)。   Thus, after fitting the mouth portion 2a of the rubber balloon body 2 into the outer fitting state from the upper wall 21 side at a position below the protrusion 23 for removal prevention on the peripheral side wall 25 of the upper body 20, The upper body 20 and the bottom body 30 are faced to each other, and the peripheral side wall 35 of the bottom body 30 is disposed in an externally fitted state on the peripheral side wall 25 of the upper body 20. If pushed to the side, the first locking ridge 24 of the upper body 20 is pushed to the lower wall 31 side from the second locking ridge 34 of the bottom body 30, and the first locking ridge Since 24 is engaged with the second locking protrusion 34 (see FIG. 2), the upper body 20 and the bottom body 30 are fitted and integrated, and thus the flying rubber balloon 1 is obtained. The upper body 20 and the bottom body 30 that are integrated with each other form a substantially cylindrical hollow blowing member 3, and an opening 22 is formed at the center of the upper wall 21 of the blowing member 3. In addition, an opening 32 is formed in the central portion of the lower wall 31 of the blowing member 3 (see FIG. 2).

図2に示すように、前記飛行ゴム風船1において、上部体20の周側壁25と底部体30の周側壁35との間における抜脱抑止用突起部23より下方に受容空間26が形成されており、即ち上部体20の周側壁25と底部体30の拡径壁部33との間における抜脱抑止用突条部23より下方に受容空間26が形成されており、該受容空間26内にゴム風船本体2の口部2aが収容されている。そして、上部体20の抜脱抑止用突起部23と底部体30の周側壁35(拡径壁部33)との隙間が、ゴム風船本体の口部2aの外径よりも小さい(図2に示すように抜脱抑止用突起部23と周側壁35との隙間は口部2aの縦断面の径(肉厚口部2aの厚さ)よりも小さい)ので、強い力が加わってもゴム風船本体の口部2aが前記吹き口部材(上部体と底部体の嵌合一体化物)3から抜脱しない(離脱しない)。即ち、強い力が加わっても吹き口部材(上部体と底部体の嵌合一体化物)3がゴム風船本体2から離脱することがない。前記構成の飛行ゴム風船1に対して、日本玩具協会の改定玩具安全基準書ST−2012(平成24年10月3日発行)の5.22.6.1に記載の引張試験一般手順に従って試験を行ったところ、70N(ニュートン)の強い力を加えても吹き口部材3はゴム風船本体2から離脱しなかった。また、前記構成の飛行ゴム風船1に対して、前記改定玩具安全基準書ST−2012の5.22.5に記載のトルク試験を行ったが、吹き口部材3はゴム風船本体2から離脱しなかったし、分解もなかった。   As shown in FIG. 2, in the flying rubber balloon 1, a receiving space 26 is formed below the protrusion 23 for preventing removal between the peripheral side wall 25 of the upper body 20 and the peripheral side wall 35 of the bottom body 30. In other words, a receiving space 26 is formed below the protrusion 23 for preventing removal between the peripheral side wall 25 of the upper body 20 and the diameter-enlarging wall portion 33 of the bottom body 30. The mouth 2a of the rubber balloon body 2 is accommodated. And the clearance gap between the protrusion part 23 for extraction | desorption suppression of the upper body 20 and the surrounding side wall 35 (expansion wall part 33) of the bottom part 30 is smaller than the outer diameter of the opening | mouth part 2a of a rubber balloon main body (FIG. As shown in the figure, the clearance between the protrusion 23 for removal prevention and the peripheral side wall 35 is smaller than the diameter of the longitudinal section of the mouth portion 2a (the thickness of the thick mouth portion 2a). The mouth portion 2a of the main body does not pull out (do not leave) from the blowing member 3 (an integrated body of the upper body and the bottom body) 3. That is, even if a strong force is applied, the blowout member (fitted and integrated body of the upper body and the bottom body) 3 does not separate from the rubber balloon body 2. The flying rubber balloon 1 having the above-described configuration is tested according to the general procedure for tensile testing described in 5.2.6.1 of the revised toy safety standard ST-2012 (issued on October 3, 2012) of the Japan Toy Association. As a result, the blowing member 3 did not leave the rubber balloon body 2 even when a strong force of 70 N (Newton) was applied. The torque test described in 5.22.5 of the revised toy safety standard ST-2012 was performed on the flying rubber balloon 1 having the above-described configuration. There was no disassembly.

上記構成の飛行ゴム風船1のゴム風船本体2内に吹き口部材3の開口部から空気を注入して膨らませた後、空中に手放すと吹き口部材3の下壁31の開口部32より空気が外に噴出し、この噴出力が推進力となってゴム風船1が略垂直方向に上昇していく。この時、前述したように回転用突起8の右側面8aの上下方向の長さmが左側面8bの上下方向の長さnよりも大きくなっているので、吹き口部材3の中空空間内を空気が上から下方に向けて流れる際に、回転用突起8の周囲では、右側面8a側が左側面8b側よりも負圧になり、従って図3、5において短い点線矢印で示すように回転用突起8を負圧側(右側面側)に移動させる力が作用するものとなるので、吹き口部材3に対して図中長い実線矢印で示すような方向に回転力が生じ、ひいてはゴム風船本体2にその軸線Lを中心とする回転力が付与され、ゴム風船1は回転しながら飛行する(図3、5における長い実線矢印方向に回転する)。このように回転しながら飛行するという斬新な形態で飛行するものとなるので、一層目立つと共に興趣性もより向上させることができる。更に、ゴム風船本体2の回転に伴って螺旋状模様9も動いて刻々と変化するので、回転していることを目立たせることができると共に、より美麗なものとなし得て興趣性を一層向上させることができる。かつ、ゴム風船本体2内に充填された空気が吹き口部材3内を通過する際にその少なくとも一部が吹き口部材3内を還流(対流)するので、高い吹鳴音を発生しながら空中を飛行する。   After inflating the air balloon body 2 of the flying rubber balloon 1 having the above structure by injecting air from the opening portion of the blowing member 3 and inflating it, air is released from the opening portion 32 of the lower wall 31 of the blowing member 3. The rubber balloon 1 ascends in a substantially vertical direction. At this time, as described above, the vertical length m of the right side surface 8a of the rotation protrusion 8 is larger than the vertical length n of the left side surface 8b. When the air flows from the top to the bottom, the right side 8a side is more negative than the left side 8b side around the rotation protrusion 8, and therefore, as shown by the short dotted arrows in FIGS. Since a force for moving the protrusion 8 to the negative pressure side (right side surface) acts, a rotational force is generated in the direction shown by the long solid arrow in the drawing with respect to the blower member 3, and consequently the rubber balloon body 2 Is applied with a rotational force about the axis L, and the rubber balloon 1 flies while rotating (rotates in the direction of the long solid arrow in FIGS. 3 and 5). Thus, since it will fly in the novel form of flying while rotating, it will be more conspicuous and more interesting. Furthermore, as the rubber balloon body 2 rotates, the spiral pattern 9 also moves and changes every moment, so that it can be noticed that it is rotating, and it can be made more beautiful, further improving the interest. Can be made. In addition, when the air filled in the rubber balloon body 2 passes through the air outlet member 3, at least a part of the air recirculates (convects) in the air outlet member 3, so that the air blows in the air while generating a high sound. To fly.

次に、本発明の他の実施形態に係る飛行ゴム風船を図6〜10に示す。この飛行ゴム風船1は、ゴム風船本体2と、上面及び下面に開口部が設けられた略円柱形状の中空部材からなる上部体60と、上面及び下面に開口部が設けられた略円柱形状の中空部材からなる底部体70とを備える。   Next, a flying rubber balloon according to another embodiment of the present invention is shown in FIGS. This flying rubber balloon 1 includes a rubber balloon body 2, an upper body 60 made of a substantially cylindrical hollow member having openings on the top and bottom surfaces, and a substantially cylindrical shape having openings on the top and bottom surfaces. A bottom body 70 made of a hollow member.

前記ゴム風船本体2は、図6に示すように、略長尺状のゴム風船からなり、先端部が膨隆状に形成される一方、基端部に厚肉の口部2aが形成されている(図7参照)。前記ゴム風船本体2の外周面には風船本体2の軸線Lを中心とする螺旋状の色模様9が付されている(図6参照)。   As shown in FIG. 6, the rubber balloon main body 2 is formed of a substantially long rubber balloon. The tip end portion is formed in a bulging shape, and the thick mouth portion 2 a is formed at the base end portion. (See FIG. 7). A spiral color pattern 9 centered on the axis L of the balloon body 2 is attached to the outer peripheral surface of the rubber balloon body 2 (see FIG. 6).

前記上部体60は、図9に示すように、下端を全開口した略円柱形状の中空部材からなり、その上壁61の中央部に開口部62が形成されている。図9において、67は、上部体60の下面の開口部である。前記上部体60は、合成樹脂の成形体である。前記上部体60の周側壁65の外面に複数個の第1係止用凸部64が外方に向けて突設されている。前記複数個の第1係止用凸部64は、上部体60の周側壁65の外面において周方向に沿って互いに離間して設けられている(図8、10参照)。更に、前記上部体60の周側壁65の外面における第1係止用凸部64より上方側の位置に複数個の抜脱抑止用突起部63が外方に向けて突設されている。前記複数個の抜脱抑止用突起部63は、上部体60の周側壁65の外面において周方向に沿って互いに離間して設けられている(図8、10参照)。   As shown in FIG. 9, the upper body 60 is formed of a substantially cylindrical hollow member having a fully open lower end, and an opening 62 is formed at the center of the upper wall 61. In FIG. 9, 67 is an opening on the lower surface of the upper body 60. The upper body 60 is a synthetic resin molded body. A plurality of first locking projections 64 project outward from the outer surface of the peripheral side wall 65 of the upper body 60. The plurality of first locking convex portions 64 are provided apart from each other along the circumferential direction on the outer surface of the peripheral side wall 65 of the upper body 60 (see FIGS. 8 and 10). Further, a plurality of removal restraining projections 63 project outwardly from the outer surface of the peripheral side wall 65 of the upper body 60 at positions above the first locking projections 64. The plurality of pull-out preventing projections 63 are provided apart from each other along the circumferential direction on the outer surface of the peripheral side wall 65 of the upper body 60 (see FIGS. 8 and 10).

そして、前記上部体60を上面視したときに抜脱抑止用突起部63と第1係止用凸部64とが重なり合わない態様で周方向に交互に配置されている(図10参照)。   Then, when the upper body 60 is viewed from above, the protrusions 63 for preventing removal and the first protrusions 64 for locking are alternately arranged in the circumferential direction so as not to overlap (see FIG. 10).

前記上部体60の周側壁65の内面に、回転用突起8、8が対向状態に突設されている(図8参照)。この回転用突起8、8は、いずれも上部体60の中空内部空間の中心位置から該回転用突起8を見た際に、図9に示すように回転用突起8の右側面8aの上下方向の長さmが左側面8bの上下方向の長さnよりも大きくなっている。   On the inner surface of the peripheral side wall 65 of the upper body 60, rotation protrusions 8, 8 are provided so as to face each other (see FIG. 8). When the rotation protrusions 8 are viewed from the center position of the hollow internal space of the upper body 60 as shown in FIG. 9, the rotation protrusions 8 are vertically aligned with the right side surface 8a of the rotation protrusion 8 as shown in FIG. Is longer than the length n in the vertical direction of the left side surface 8b.

前記底部体70は、図9に示すように、上端を全開口した略円柱形状の中空部材からなり、その下壁71の中央部に開口部72が形成されている。図9において、77は、底部体70の上面の開口部である。前記底部体70は、合成樹脂の成形体である。前記底部体70の周側壁75の内面に第2係止用凸条部74が内方に向けて突設されている。この第2係止用凸条部74は、底部体70の周側壁75の内面において周方向に沿って延ばされた環状の凸条部である(図8、9参照)。   As shown in FIG. 9, the bottom body 70 is made of a substantially cylindrical hollow member whose upper end is fully opened, and an opening 72 is formed at the center of the lower wall 71. In FIG. 9, reference numeral 77 denotes an opening on the upper surface of the bottom body 70. The bottom body 70 is a molded body of synthetic resin. A second locking protrusion 74 projects inward from the inner surface of the peripheral side wall 75 of the bottom body 70. The second locking ridge 74 is an annular ridge extending along the circumferential direction on the inner surface of the peripheral side wall 75 of the bottom body 70 (see FIGS. 8 and 9).

しかして、前記上部体60の周側壁65における抜脱抑止用突起部63より下の位置に、前記ゴム風船本体2の口部2aを上壁61側から外嵌状態に嵌着した後、前記上部体60と前記底部体70とをそれぞれの全開口側を向き合わせて上部体60の周側壁65に底部体70の周側壁75を略外嵌状態に配置し、更に上部体60を底部体70側に押し込めば、上部体60の第1係止用凸部64が底部体70の第2係止用凸条部74より下壁71側に押し込まれて、第1係止用凸部64が第2係止用凸条部74に係合される(図7(B)参照)ので、上部体60と底部体70とが嵌合一体化され、こうして飛行ゴム風船1が得られる。なお、嵌合一体化された上部体60と底部体70とで、略円柱形状の中空の吹き口部材3が構成され、前記吹き口部材3の上壁61の中央部に開口部62が形成され、前記吹き口部材3の下壁71の中央部に開口部72が形成されている(図7参照)。   Thus, after fitting the mouth portion 2a of the rubber balloon body 2 into the outer fitting state from the upper wall 61 side at a position below the protrusion 63 for removal prevention on the peripheral side wall 65 of the upper body 60, The upper body 60 and the bottom body 70 are opposed to each other with their respective openings facing each other, and the peripheral side wall 75 of the bottom body 70 is disposed in a substantially externally fitted state on the peripheral side wall 65 of the upper body 60. When pushed into the side 70, the first locking convex portion 64 of the upper body 60 is pushed into the lower wall 71 side from the second locking convex portion 74 of the bottom body 70, and the first locking convex portion 64. Is engaged with the second locking ridge 74 (see FIG. 7B), the upper body 60 and the bottom body 70 are fitted and integrated, and thus the flying rubber balloon 1 is obtained. The upper body 60 and the bottom body 70 which are integrated with each other form a substantially cylindrical hollow member 3 and an opening 62 is formed at the center of the upper wall 61 of the member 3. In addition, an opening 72 is formed at the center of the lower wall 71 of the air outlet member 3 (see FIG. 7).

図7に示すように、前記飛行ゴム風船1において、上部体60の周側壁65と底部体70の周側壁75との間における抜脱抑止用突起部63より下方に受容空間66が形成されており、該受容空間66内にゴム風船本体2の口部2aが収容されている。そして、上部体60の抜脱抑止用突起部63と底部体70の周側壁75との隙間が、ゴム風船本体の口部2aの外径よりも小さい(図7(A)に示すように抜脱抑止用突起部63と周側壁75との隙間は口部2aの縦断面の径(肉厚口部2aの厚さ)よりも小さい)ので、強い力が加わってもゴム風船本体の口部2aが前記吹き口部材(上部体と底部体の嵌合一体化物)3から抜脱しない(離脱しない)。即ち、強い力が加わっても吹き口部材(上部体と底部体の嵌合一体化物)3がゴム風船本体2から離脱することがない。前記構成の飛行ゴム風船1に対して、日本玩具協会の改定玩具安全基準書ST−2012(平成24年10月3日発行)の5.22.6.1に記載の引張試験一般手順に従って試験を行ったところ、70N(ニュートン)の強い力を加えても吹き口部材3はゴム風船本体2から離脱しなかった。また、前記構成の飛行ゴム風船1に対して、前記改定玩具安全基準書ST−2012の5.22.5に記載のトルク試験を行ったが、吹き口部材3はゴム風船本体2から離脱しなかったし、分解もなかった。   As shown in FIG. 7, in the flying rubber balloon 1, a receiving space 66 is formed below the protrusion 63 for preventing desorption between the peripheral side wall 65 of the upper body 60 and the peripheral side wall 75 of the bottom body 70. The mouth portion 2 a of the rubber balloon main body 2 is accommodated in the receiving space 66. And the clearance gap between the protrusion 63 for pulling out prevention of the upper body 60 and the peripheral side wall 75 of the bottom body 70 is smaller than the outer diameter of the mouth part 2a of the rubber balloon body (as shown in FIG. 7A). Since the gap between the protrusion 63 for disinhibition and the peripheral side wall 75 is smaller than the diameter of the longitudinal section of the mouth portion 2a (the thickness of the thick mouth portion 2a), the mouth portion of the rubber balloon main body is applied even if a strong force is applied. 2a is not pulled out (not detached) from the blow-off member (fitted and integrated body of the upper body and the bottom body) 3. That is, even if a strong force is applied, the blowout member (fitted and integrated body of the upper body and the bottom body) 3 does not separate from the rubber balloon body 2. The flying rubber balloon 1 having the above-described configuration is tested according to the general procedure for tensile testing described in 5.2.6.1 of the revised toy safety standard ST-2012 (issued on October 3, 2012) of the Japan Toy Association. As a result, the blowing member 3 did not leave the rubber balloon body 2 even when a strong force of 70 N (Newton) was applied. The torque test described in 5.22.5 of the revised toy safety standard ST-2012 was performed on the flying rubber balloon 1 having the above-described configuration. There was no disassembly.

上記構成の飛行ゴム風船1のゴム風船本体2内に吹き口部材3の開口部から空気を注入して膨らませた後、空中に手放すと吹き口部材3の下壁71の開口部72より空気が外に噴出し、この噴出力が推進力となってゴム風船1が略垂直方向に上昇していく。この時、前述したように回転用突起8の右側面8aの上下方向の長さmが左側面8bの上下方向の長さnよりも大きくなっているので、吹き口部材3の中空空間内を空気が上から下方に向けて流れる際に、回転用突起8の周囲では、右側面8a側が左側面8b側よりも負圧になり、従って図8、10において短い点線矢印で示すように回転用突起8を負圧側(右側面側)に移動させる力が作用するものとなるので、吹き口部材3に対して図中長い実線矢印で示すような方向に回転力が生じ、ひいてはゴム風船本体2にその軸線Lを中心とする回転力が付与され、ゴム風船1は回転しながら飛行する(図8、10における長い実線矢印方向に回転する)。このように回転しながら飛行するという斬新な形態で飛行するものとなるので、一層目立つと共に興趣性もより向上させることができる。更に、ゴム風船本体2の回転に伴って螺旋状模様9も動いて刻々と変化するので、回転していることを目立たせることができると共に、より美麗なものとなし得て興趣性を一層向上させることができる。かつ、ゴム風船本体2内に充填された空気が吹き口部材3内を通過する際にその少なくとも一部が吹き口部材3内を還流(対流)するので、高い吹鳴音を発生しながら空中を飛行する。   After inflating the air balloon body 2 of the flying rubber balloon 1 having the above-described structure by injecting air from the opening portion of the blowing member 3 and releasing it, the air is released from the opening portion 72 of the lower wall 71 of the blowing member 3. The rubber balloon 1 ascends in a substantially vertical direction. At this time, as described above, the vertical length m of the right side surface 8a of the rotation protrusion 8 is larger than the vertical length n of the left side surface 8b. When the air flows from the top to the bottom, the right side 8a side is more negative than the left side 8b side around the rotation projection 8, and accordingly, as shown by the short dotted arrows in FIGS. Since a force for moving the protrusion 8 to the negative pressure side (right side surface) acts, a rotational force is generated in the direction shown by the long solid arrow in the drawing with respect to the blower member 3, and consequently the rubber balloon body 2 Is applied with a rotational force about the axis L, and the rubber balloon 1 flies while rotating (rotates in the direction of a long solid arrow in FIGS. 8 and 10). Thus, since it will fly in the novel form of flying while rotating, it will be more conspicuous and more interesting. Furthermore, as the rubber balloon body 2 rotates, the spiral pattern 9 also moves and changes every moment, so that it can be noticed that it is rotating, and it can be made more beautiful, further improving the interest. Can be made. In addition, when the air filled in the rubber balloon body 2 passes through the air outlet member 3, at least a part of the air recirculates (convects) in the air outlet member 3, so that the air blows in the air while generating a high sound. To fly.

なお、上記後者の実施形態(図6〜10)では、第1係止用凸部64を6個設けた構成としているが、その数は特に限定されるものではなく、例えば、1〜5個としても良いし、或いは7個以上としても良い。   In the latter embodiment (FIGS. 6 to 10), six first locking convex portions 64 are provided, but the number is not particularly limited, and for example, 1 to 5 Or 7 or more.

なお、上記後者の実施形態(図6〜10)では、抜脱抑止用突起部63を6個設けた構成としているが、その数は特に限定されるものではなく、例えば、1〜5個としても良いし、或いは7個以上としても良い。   In the latter embodiment (FIGS. 6 to 10), the number of protrusions 63 for preventing removal is provided, but the number is not particularly limited. Or 7 or more.

また、前記実施形態(図1〜10)では、回転用突起8は、右側面8aの上下方向の長さmが左側面8bの上下方向の長さnよりも大きくなるように構成されているが、これとは逆に、左側面8bの上下方向の長さが右側面8aの上下方向の長さよりも大きくなるように構成しても良いことは言うまでもない(この場合、飛行ゴム風船1が回転する向きは逆になる)。   Moreover, in the said embodiment (FIGS. 1-10), the protrusion 8 for rotation is comprised so that the length m of the up-down direction of the right side surface 8a may become larger than the length n of the up-down direction of the left side surface 8b. However, on the contrary, it goes without saying that the length of the left side surface 8b in the vertical direction may be larger than the length of the right side surface 8a in the vertical direction (in this case, the flying rubber balloon 1 is The direction of rotation is reversed.)

また、前記実施形態(図1〜10)では、回転用突起8を2個設けた構成としているが、その数は特に限定されるものではなく、1個としても良いし、或いは3個以上としても良い。   Moreover, in the said embodiment (FIGS. 1-10), although it has set as the structure which provided the two protrusions 8 for rotation, the number is not specifically limited, It is good also as one, or as three or more Also good.

中でも、前記回転用突起8は複数個設けられて、これら複数個の回転用突起のいずれにおいても、その左右両側面8a、8bのうち同じ側の側面の上下方向の長さが、他方側の側面の上下方向の長さよりも大きくなるように構成されているのが好ましい。このような構成を採用することで、ゴム風船本体2により強い回転力を付与することができる。   Among them, a plurality of the rotation protrusions 8 are provided, and in any of the plurality of rotation protrusions, the length in the vertical direction of the side surface on the same side of the left and right side surfaces 8a and 8b is the other side. It is preferable that the length of the side surface is greater than the vertical length. By adopting such a configuration, a strong rotational force can be applied to the rubber balloon body 2.

なお、前記実施形態では、回転用突起8を設けた構成としているが、このような回転用突起8を設けない構成としてもよい。   In addition, in the said embodiment, although it is set as the structure which provided the protrusion 8 for rotation, it is good also as a structure which does not provide such a protrusion 8 for rotation.

本発明に係る飛行ゴム風船は、例えば、玩具として用いられる他、プロ野球やサッカー等の試合においてスタンドで観客が自身の好きなチームを応援等するために空中に飛行させて用いられるが、特にこれら用途に限定されるものではない。   The flying rubber balloon according to the present invention is used, for example, as a toy, and is used by flying in the air in order to support a favorite team at a stand in a game such as professional baseball or soccer. It is not limited to these uses.
