Description
本発明は、ドアベル，警報ベル，動物よけ鈴、呼び鈴等、広い分野にて利用できる共鳴性の高いベルに関する。 The present invention relates to a highly resonant bell that can be used in a wide range of fields such as doorbells, alarm bells, animal bells, and doorbells.
従来から人の来訪を知らせるドアベル、人に警報する警報ベル、熊等の動物よけの為のベル、縁起物としての鈴等、各種ベルが提案されているが、従来のベルはいずれも大きく振らないと鳴らないものであり音色も単調であった。
特許文献１には金属薄板で形成した空所に転動子を収容した鈴を開示し、特許文献２には上下の共鳴体の間に球を保持した鈴おもちゃを開示するが、いずれも大きな振れにて音が出るものである。
また、従来のベルには図４に示すように、りん部１１２の内側にひも等の吊り下げ部材１１１を用いておもり１１４等を吊り下げたものがある。
この場合におもり１１４が振れる周期は、吊り下げ部材１１１の長さで決まってしまう問題があった。
また、このように吊り下げた打鈴球のタイプにあっては、球がりん部の内壁と当たる角度が一定である。
しかも、りん部を振っても球に慣性力が働き、すぐには鳴らない問題があった。
Various bells have been proposed, such as doorbells that alert people to visits, alarm bells that alert people, bells for animal protection such as bears, bells as lucky charms, etc. Otherwise, it would not sound and the tone was also monotonous.
Patent Literature 1 discloses a bell that houses a rolling element in a space formed by a thin metal plate, and Patent Literature 2 discloses a bell toy that holds a sphere between upper and lower resonators. Sound is produced by shaking.
Further, as shown in FIG. 4, there is a conventional bell in which a weight 114 and the like are suspended by using a suspension member 111 such as a string inside a phosphorus portion 112.
In this case, there is a problem that the period in which the weight 114 swings is determined by the length of the suspension member 111.
Further, in the type of hitting ball suspended in this way, the angle at which the ball hits the inner wall of the phosphorus portion is constant.
Moreover, there is a problem that even if the phosphorus part is shaken, inertial force acts on the ball and it does not sound immediately.
本発明は、小さな振れで鳴り、音の大きさや音色の調整が容易なベルの提供を目的とする。 It is an object of the present invention to provide a bell that rings with a small amount of vibration and allows easy adjustment of sound volume and tone color.
本発明に係る転動体ベルは、ベルが水平方向に移動することで鳴るベルであって、当該ベルはベース部と、当該ベース部に直接又は間接的に支持されたりん部とを有し、前記ベース部は凹部を有し、当該凹部には転動体が転動可能に載置されていて、前記ベルが水平方向に移動すると前記転動体が慣性力によりベース部の凹部の底面に沿ってベルの移動方向とは逆方向に一旦転がり、りん部の内壁に当たった後に反対側に転がるものであり、前記凹部の底面形状にて転動体がりん部の内壁に当たる当接角度又は高さを変えることで音の調整を可能にしたことを特徴とする。
ここで転動体は、凹部の底面を転がり、りん部に当たるものをいい、転がるものであれば形状に制限はないが、転がりやすいものとしては球体に近いものが好ましい。
また、ベース部とりん部とは所定の隙や空間を有するように連結するのがよく、それにより、音の鳴り響きが良くなる。
本発明は、この球体等の転動体の転動する周期（速さ）をベース部の凹部の底面形状（転動面形状）にて調整した点にある。
このようにすると、従来のベルは吊り下げ部材の長さによる影響が大きく、音の調整が困難であったのに対して、本発明は、凹部の底面の曲率等にて容易に調整可能である。
The rolling element bell according to the present invention is a bell that rings when the bell moves in the horizontal direction, the bell having a base part and a phosphorus part supported directly or indirectly by the base part, the base portion has a recess, the rolling elements to the recesses have been placed rollably along the bottom surface of the recess of the base part and the rolling elements and the bell is moved in the horizontal direction by the inertial force Rolls in the direction opposite to the bell movement direction, hits the inner wall of the phosphorus part, then rolls to the opposite side, and the contact angle or height at which the rolling element hits the inner wall of the phosphorus part in the bottom shape of the recess The feature is that the sound can be adjusted by changing .
Here, the rolling element refers to one that rolls on the bottom surface of the concave portion and hits the phosphorus portion, and there is no limitation on the shape as long as it rolls, but a rolling element that is close to a sphere is preferable.
Further, the base portion and the phosphorus portion are preferably connected so as to have a predetermined gap or space, thereby improving the sounding of the sound.
The present invention resides in that the rolling cycle (speed) of the rolling element such as a sphere is adjusted by the bottom surface shape (rolling surface shape) of the concave portion of the base portion.
In this way, the conventional bell is greatly influenced by the length of the suspension member, and it is difficult to adjust the sound. On the other hand, the present invention can be easily adjusted by the curvature of the bottom surface of the recess. is there.
本発明に係るベルは、球体等の転動体がベース部に形成した凹部形状からなる転動面を転がるようにしたので、転動面の形状により転動体の転がりやすさ、転がり速度を調整することができる。
そこで、転動面の形状を中央部が最も低くなる球面形状にし、球面の曲率を小さくすれば転動体が転がりにくくなり、転動体がりん部に当たる力がそれだけ弱くなるので小さい音になる。
また、ベルの揺れが小さい場合には、転動体がりん部に当たる前に中央側に戻ることで音が鳴らない。
また、逆に転動面の曲率を大きくし、平坦に近い状態にすると小さい揺れでも音が鳴る。
転動面の形状は必ずしも球面形状にする必要はなく、転動体の転がる方向を規制した溝部を有してもよく、例えば中心から周縁部に向けて放射状に形成したり、うず巻き状に溝部を形成してもよい。
また、凹部の底面であって、少なくとも中央部に所定の曲率からなる球面形状部を有するようにすると、この球面形状部にて転動体の転がる周期やりん部に当たる強さの調整がしやすい。
In the bell according to the present invention, a rolling element such as a sphere rolls on a rolling surface formed of a concave shape formed in the base portion, and therefore, the rolling element is adjusted according to the shape of the rolling surface for ease of rolling and rolling speed. be able to.
Therefore, if the rolling surface is formed into a spherical shape with the lowest central portion and the curvature of the spherical surface is made small, the rolling element becomes difficult to roll, and the force that the rolling element hits the phosphorus part becomes so weak that the sound becomes small.
When the bell swing is small, no sound is produced by returning to the center before the rolling element hits the phosphorus part.
On the other hand, if the curvature of the rolling surface is increased to make it nearly flat, a sound will be produced even with small shaking.
The shape of the rolling surface does not necessarily have to be a spherical shape, and may have a groove that regulates the rolling direction of the rolling element, for example, it may be formed radially from the center toward the peripheral edge, or the groove may be spirally formed. It may be formed.
Further, if the bottom surface of the concave portion has a spherical surface portion having a predetermined curvature at least in the central portion, it is easy to adjust the rolling cycle of the rolling element and the strength hitting the phosphorus portion.
従来の糸等で吊り下げた打鈴球の場合には、りん部の内壁との当たる角度が一定であるのに対して、本発明に係るベルは、ベース部の転動面の傾斜角度、りん部の内壁の角度によって転動体の当たり方が変わるので、それらの角度や転動体の当たる高さを調整することができる。
また、転動体の大きさや材質によってもりん部の鳴り方が変化するが、転動体の取り替えも容易である。
In the case of a hitting ball suspended by a conventional thread or the like, the angle of contact with the inner wall of the phosphorus portion is constant, whereas the bell according to the present invention has an inclination angle of the rolling surface of the base portion, Since the way of contact with the rolling elements changes depending on the angle of the inner wall of the phosphorus portion, the angle and the height at which the rolling elements hit can be adjusted.
Moreover, although the ringing method of the phosphorus portion varies depending on the size and material of the rolling elements, the rolling elements can be easily replaced.
本発明に係るベルは、転動体のりん部への当たり方を調整することで、鳴る音の高さ，強さ，音色等の調整が可能である。
特に転動体の転がる周期，速度を底面の曲率，転がり軌道の規制溝等によって調整が容易である。
また、転動面の曲率を大きくし平坦な形状に近づけると、微細な揺動によっても充分な運動エネルギーを与えることができ、大きな音になる。
The bell according to the present invention can adjust the pitch, strength, timbre, and the like of the sound produced by adjusting how the rolling element hits the phosphorus portion.
In particular, the rolling cycle and speed of the rolling element can be easily adjusted by the curvature of the bottom surface, the rolling groove regulation groove, and the like.
Further, when the curvature of the rolling surface is increased to approach a flat shape, sufficient kinetic energy can be given even by fine oscillation, resulting in a loud sound.
本発明に係るベル１０は、図１に断面構造例を示すようにベース部１１とりん部１２からなり、ベース部１１の上面側に形成した凹部の底面形状からなる転動面１１ａに球形状等の転動体２０を転がり載置してある。
図１では図示を省略したが、ベース部１１にりん部１２が連結支持されていて、支持構造に制限がない。
例えば、りん部１２の内側でベース部と連結してもよく、りん部１２の外側でベース部１１と連結してもよい。
共鳴音が鳴りやすいようにベース部１１とりん部１２の間には隙間部１３を有する。
A bell 10 according to the present invention includes a base portion 11 and a phosphorus portion 12 as shown in FIG. 1 as an example of a cross-sectional structure, and has a spherical shape on a rolling surface 11a having a bottom surface shape of a recess formed on the upper surface side of the base portion 11. A rolling element 20 such as a roller is mounted.
Although not shown in FIG. 1, the phosphorus portion 12 is connected to and supported by the base portion 11, and the support structure is not limited.
For example, it may be connected to the base portion inside the phosphorus portion 12, or may be connected to the base portion 11 outside the phosphorus portion 12.
A gap 13 is provided between the base portion 11 and the phosphorus portion 12 so that a resonance sound is easily generated.
球面形状になっている転動面の曲率Ｒと音圧との関係を調査したので、以下説明する。
りん部１２は黄銅からなり、外径寸法φ１＝５４ｍｍ，下端部の内径寸法φ２＝４８ｍｍ，高さ寸法Ｈ＝３４．５ｍｍの釣鐘形状に設定した。
ベース部は、上面部の外径寸法φ３＝４７ｍｍ，隙間部１３の水平方向寸法０．５ｍｍに設定した。
転動体２０は、直径１１ｍｍ，重さ５ｇの鉄球を用いた。
転動面１１ａの曲率Ｒ＝７０，８０，９０，１００，１５０，２００ｍｍの６種類を試作し、水平方向に速度３０，０００ｍｍ／ｍｉｎで約１００ｍｍ移動させ、音圧測定用マイクをベルの移動後の位置から１００ｍｍ離れた位置に配置した。
このときの音圧（Ｐａ）の値を図２，３に示す。
音圧を示す縦目盛りの大きさが一致していないので、目盛りの大きさを考慮しつつ比較する。
転動体（鉄球）のりん部への当たり方は、ベルの移動方向とは逆に一旦転がり、りん部の内壁に当たった後に反対側に転がり、りん部の内壁に当たるパターンを示した。
曲率Ｒが小さい程、最初の当たり音が小さく、次の当たり音の方が大きくなるものの、転動体が揺動方向に転がり、りん部に当たる２回目の音圧レベルは曲率Ｒが小さいほど、小さくなる傾向を示した。
曲率Ｒが大きい程、転動体２０が転がりやすく音圧も大きくなっている。
これらの実験結果から、ベース部１１の転動面の形状により音圧の調整が可能であることが明らかになった。
The relationship between the curvature R of the rolling surface having a spherical shape and the sound pressure has been investigated, and will be described below.
The phosphorus portion 12 is made of brass and has a bell shape with an outer diameter of φ 1 = 54 mm, an inner diameter of the lower end of φ 2 = 48 mm, and a height of H = 34.5 mm.
The base part was set to have an outer diameter dimension φ 3 = 47 mm of the upper surface part and a horizontal dimension of 0.5 mm of the gap part 13.
As the rolling element 20, an iron ball having a diameter of 11 mm and a weight of 5 g was used.
Six types of curvatures R = 70, 80, 90, 100, 150, and 200 mm of the rolling surface 11a were prototyped, moved about 100 mm at a speed of 30,000 mm / min in the horizontal direction, and the sound pressure measurement microphone was moved by the bell It arrange | positioned in the position 100 mm away from the back position.
The value of the sound pressure (Pa) at this time is shown in FIGS.
Since the vertical scales indicating the sound pressure do not match, the comparison is made in consideration of the scales.
The rolling element (iron ball) hits the phosphorus part in a pattern opposite to the direction of the bell movement, once hitting the inner wall of the phosphorus part, then rolling to the opposite side, and hitting the inner wall of the phosphorus part.
As the curvature R is smaller, the first hit sound is smaller and the next hit sound is larger, but the rolling element rolls in the swinging direction, and the second sound pressure level hitting the phosphorus portion is smaller as the curvature R is smaller. Showed a tendency to become.
The greater the curvature R, the easier the rolling element 20 rolls and the sound pressure increases.
From these experimental results, it became clear that the sound pressure can be adjusted by the shape of the rolling surface of the base portion 11.
また、図１（ｂ）に示すように転動体の当たり方向とりん部１２の内壁との当接角度θ及び当接高さによっても音圧が変化する。
そこで、ベース部１１の転動面の傾斜角度、りん部１２の内壁の立設角度を調整することでも音圧の調整が可能であり、最も音が出やすい高さに調整するのが好ましい。
Further, as shown in FIG. 1B, the sound pressure also varies depending on the contact angle θ and the contact height between the contact direction of the rolling elements and the inner wall of the phosphorus portion 12.
Therefore, it is possible to adjust the sound pressure by adjusting the inclination angle of the rolling surface of the base portion 11 and the standing angle of the inner wall of the phosphorus portion 12, and it is preferable to adjust the height so that sound is most easily emitted.
