Description

  The present invention relates to a triangle handle in which a triangle does not rotate during performance.

  Until now, when playing a triangle, tie a string or thread to the upper corner (called the apex angle) of the triangle that is a triangle, hook the stretched string on your finger, and support the beater with your other hand. I was playing and singing. At this time, the finger and the triangle are connected by one string, that is, by one point. Therefore, if the beater is not applied perpendicularly to the triangle surface when viewed from above, the triangle will rotate around the apex angle, and after that, it will not be possible to strike or make a reverberating sound. . If a finger and a triangle are held by one ring, they are connected by two. If the distance between the upper part of the triangle and the finger is shortened to a minimum, the rotation of the triangle can be suppressed. It is difficult to perform in a difficult state The present invention was conceived in order to make it easier for younger children and kindergartens to play triangles.

  Therefore, the upper part of the apex angle of the triangle and the flat plate of the lower part of the handle are bound with a string or a binding band so that a slight gap is formed. As shown in FIG. 6, when the binding part is enlarged, the horizontal distance between the string and the string becomes longer than the vertical length of the string, and the twist of the triangle with respect to the handle is reduced and the rotation is performed. Is suppressed and stabilized. Further, by making a gap without contacting the upper part of the apex angle of the triangle and the flat plate at the lower part of the handle, the sound of the triangle is not hindered at all. Furthermore, since the triangle is not touched by the hand holding the handle of the handle, the triangle can be sounded more reliably than in the conventional triangle holding method.

  According to the above document, among the three corners of the triangle that can be said to be a triangle, the two corner portions that are connected are nodes of vibration, and the vibration is the least. This applies to triangles of any size, and because the apex angle is a node of vibration, even if the hanging string is in contact with it, the sound reverberates without stopping the vibration. It will continue. I tried to use various sizes of binding bands on the market instead of the strings, but they were not affected at all by the sound of the triangle. A binding band of a small size is sufficient and is easy to fix. By using a binding band, it is easy to make the gap small and torsion can be further suppressed. However, if the top of the triangle apex and other objects, such as the aluminum flat plate used here, are in close contact with each other, the reverberation will be hindered and the reverberation will be worse and will not last long. This problem is solved by leaving a slight gap without contacting the top of the triangle apex and the bottom plate of the handle.

  A musical instrument called a triangle is used as a musical instrument in orchestras, for example, but is often used in concerts in the lower grades of elementary school, concerts in kindergartens, and nurseries. It seems that anyone can easily make a sound just by hitting with a beater. However, until now, since it was hung with a single string or thread from the apex angle of the triangle, the triangle would rotate like a revolving door around the apex angle unless a beater was applied perpendicularly to the triangle surface. After that, it is impossible to strike or make a sound that resonates. Triangle was an instrument that required some skill to play.

  In order to allow elementary school children and preschoolers to continue playing with a beater without rotating the triangle body, underneath the cylindrical handle, the shallow U-shaped aluminum from both ends of the handle. Pass the flat plate and bind the central part of the aluminum flat plate and the apex angle of the triangle with a string or a small binding band. At this time, the aluminum plate and the triangle are bound together so that a slight gap is formed between them. By making the gap between the aluminum flat plate and the upper portion of the triangle small, the triangle body is less likely to twist with respect to the aluminum plate, that is, the triangle handle of the present invention, and rotation is suppressed.

  The material of the shallow U-shaped flat plate that passes from both ends of the handle is aluminum. Aluminum, which has sufficient strength to hang a triangle and is easy to process, is the optimal material. The width of the flat plate bound to the triangle is preferably about the same as the thickness of the triangle. Since most of the existing triangles are 9 mm in thickness, the width of the flat plate is about 11 mm if the tie for holding the triangle and the dent for fixing the binding band are 1 mm on the left and right. The thickness is desirably about 2 mm in terms of strength. The handle that you hold with your hand is best made of a wooden cylinder with a diameter of Φ12mm and a length of about 95mm that is comfortable for both children and male adults.

  Many elementary school children and preschoolers who have already played the existing triangle have experienced that the triangle has rotated during the performance, making it difficult to play or making it difficult to play. I will. When such children use the “triangle handle” of the present invention to play a triangle, they will notice that the triangle itself does not rotate and can be played reliably, and then play the triangle with peace of mind. Will be able to.

  Triangle performance also requires a mute to stop the sounding sound. When playing along the score, the rest must be muted. There are cases where you touch the triangle with your hand holding the triangle to mute it, and there are cases where you touch the triangle with your hand hitting the beater to mute it. It is difficult to mute. When the triangle is touched and muted by hitting a beater, the timing of touching the triangle body may be delayed if the triangle body is rotating and moving. If the triangle handle of the present invention is used, the problem that the mute is delayed is solved.

  Many of the triangles have a shape close to an equilateral triangle, but some of them have a shape close to an isosceles triangle. There are various sizes of triangles. If the triangle handle of the present invention is used, the effects described so far can be exhibited for any size and shape of the triangle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, as shown in FIGS. 1 to 5, both ends of an aluminum flat plate having a length of 160 mm, a width of 11 mm, and a thickness of about 2 mm are raised up by about 32 mm, and the central portion is bent down by about 14 °.

  A dent is made inward about 1 mm from both ends of the bent flat plate center. This is because the central portion of the aluminum flat plate is bent and lowered, or has a dent, so that it is easy to fix a string or a small binding band tied by holding a triangle.

  The both ends of the aluminum flat plate are screwed to both ends of a wooden round bar having a length of about 95 mm and a diameter of about 12 mm to complete the “triangle handle” of the present invention.

  This “Triangle handle”, which is made by screwing an aluminum flat plate and a wooden round bar, is touched entirely by hand, so every part should be rounded to avoid any uncomfortable feeling.

  Triangles are relatively often played by lower elementary school children, kindergartens and preschoolers. It is difficult for those who are not very skillful in playing to keep hitting the beater perpendicular to the triangle. Even in such a case, if the “triangle handle” of the present invention is used, the rotation of the triangle body can be eliminated and the beater can be continuously hit, and the performance is not interrupted. People who are watching the performers at concerts and concerts will also be satisfied.
