Abstract

To provide a tool for stringed instrument performance having such a structure that repulsion force from a string during a stringed instrument performance is transmitted to a thumb in a dynamically advantageous method and can be borne with force of the thumb not depending upon only frictional force.SOLUTION: A tool for stringed instrument performance has a flat part 1 positioned on the cushion side of a thumb, and two front and rear rings 4, 5, and then a pick part 2 for performance formed integrally with the flat part is provided, or a flat pick on the market is used together as a substitute for the pick part for performance when necessary. When this tool is put on the thumb and viewed from the front on a nail side, the front and rear rings are coupled to the flat part on the thumb center line. Further, the front ring 4 has its thumb claw side held at a fulcrum through an arm, and the rear ring 5 has its thumb cushion side held at the fulcrum nearby the first joint of the thumb.EFFECT: This structure brings about the effect that the repulsion force received from the string during a stringed instrument performance is converted from force of turning into one direction to force of holding the thumb from both sides.SELECTED DRAWING: Figure 1

Description

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thumb pick to be used by attaching it to a thumb when playing a stringed instrument typified by a guitar or the like, or a member on which a commercially available flat topic is attached integrally with the thumb to function as a thumb pick.

 A conventional thumb pick is a simple one in which one end of an elongated member is used as a playing pick portion and the other portion is bent to form a portion to be fixed so as to be wound around a thumb.

However, in such a thumb pick, the repulsive force from the strings acts in the direction of rotating the thumb pick itself attached to the thumb. Therefore, if the fixing force is weak, the performance becomes difficult, and conversely, if it is too strong, there is a problem that the attached portion causes pain.

In order to deal with such a problem, Patent Document 1 or Patent Document 2 discloses a thumb pick in which a flexible material or a material having a large coefficient of friction is used for a portion fixed to the thumb, or a size adjusting function is added. There is.

Further, although the one shown in Patent Document 3 does not have a string-plucking mechanism as a thumb pick by itself, a commercially available flat topic is used integrally with a thumb by using an elastic band. It is an invention. Therefore, it can be regarded as something similar to the thumb pick.

 It is considered that the thumb picks described in Patent Documents 1 to 3 or something similar to the thumb picks (hereinafter collectively referred to as thumb picks) addresses the problems of the conventional thumb picks and exerts a certain effect. To be However, these have a common structure in which the band portions for fixing the playing pick portion are connected on both sides of the thumb. Therefore, the force from the playing pick portion located on the side surface of the thumb is mechanically amplified and transmitted in the direction in which the thumb pick itself is rotated, and it is supported by the frictional force between the outer peripheral portion of the thumb and the thumb pick. This is clearly a structural disadvantage.

 Therefore, the object of the present invention is to transmit the repulsive force received from the strings during playing to the thumb in a mechanically advantageous manner, and also to support it not only by the force of frictional force that cannot be freely controlled by one's own will. In other words, it is an object to provide a string instrument playing instrument that can be used for a longer period of time and has a natural sense of unity with one's fingertips.

 The instrument for playing a stringed instrument according to one embodiment of the present invention includes a flat portion 1 that is in close contact with the belly of the thumb 9, a front ring 4 connected to the tip of an arm 3 extending from the fingertip side, and a thumb of the flat portion 1. It is composed of a rear ring 5 that is connected to the base side, approximately near the first joint of the thumb.

 When the string instrument playing instrument according to the embodiment of the present invention is attached to the thumb 9 and viewed from the nail side, the arm 3 connecting the flat portion 1 and the front ring 4 is located on the center line of the thumb 9, The front ring 4 is supported by bending toward the nail side through the tip. The connection point between the flat portion 1 and the rear ring 5 is also located on the thumb center line.

 When making a thumb pick with a stringed instrument playing device alone according to an embodiment of the present invention, at least one side surface of the flat portion 1 is extended and a playing pick portion 2 is provided. When a commercially available flattopic 10 is used, it is mounted between the flat portion 1 and the thumb 9 and used as a substitute for the playing pick portion 2.

First, the nail side of the thumb is defined as the upper side, and similarly, the ventral side of the thumb is defined as the lower side.
Further, the operation of mounting the stringed instrument playing instrument according to the embodiment of the present invention on the thumb and plucking the strings of the stringed instrument from top to bottom is referred to as down picking, and the reverse operation is referred to as up picking.

When the down picking is seen from the base of the thumb 9 to the tip direction (see FIGS. 5 and 6), the upward repulsive force 12 applied to the playing pick portion 2 is centered on the front ring fulcrum 7 and the rear ring fulcrum 8. Each is converted into a clockwise force (13 ・ 14). However, the front ring fulcrum 7 is above the thumb, while the rear ring fulcrum 8 is below the thumb. Therefore, although the thumbpick as a whole has a force in the clockwise direction, the force applied to the thumb 9 is converted into a force for pinching the thumb 9 from both sides. This makes it possible to support with the original force of the thumb without depending on the frictional force on the surface of the thumb. Also, at this time, the upward repulsive force 12 applied to the playing pick portion 2 is dispersed to the front and rear two rings, and further, due to the positional relationship between the center of the thumb 9 and the front and rear ring fulcrums 7 and 8. Since the lever principle also works, it is possible to support it with a smaller force.

Further, also in up-picking, the same effect can be obtained although the direction of each force is reversed.

It is a top view which shows one Example at the time of setting it as a thumb pick by this invention simple substance. It is a side view of a mounted state showing an embodiment when the present invention is used as a thumb pick. FIG. 6 is a perspective view of a mounted state showing an embodiment when the present invention is used as a thumb pick. 1 is a front view of one embodiment of the present invention for use with a commercial flattop. FIG. 6 is a schematic diagram showing the mechanical characteristics of the front ring when the downpicking in the present invention is viewed from the base of the thumb in the distal direction. FIG. 6 is a schematic view showing mechanical characteristics of a rear ring when the down picking in the present invention is viewed from a base of a thumb in a distal direction. 1 is an example of a member before bending when the present invention is cut out from a continuous plate material and formed.

FIG. 1 is a plan view of a thumb pick according to an embodiment of the present invention.
FIG. 2 is a side view when the thumb is attached, and FIG. 3 is a perspective view when the thumb is attached.
The embodiment of the present invention shown in FIGS. 1 to 3 is to be used by being attached to the tip portion from the first joint of the thumb 9, and includes the flat portion 1, the arm 3, the front ring 4, and the rear ring 5. It has a playing pick section (2) as required.
FIG. 1 is a view of the thumb pick viewed from the nail side (right side of FIG. 2) of the thumb 9 to which the thumb pick is attached.

In the embodiment shown in FIGS. 1 to 3, the flat portion 1, the playing pick portion 2, the arm 3, the front ring 4, and the rear ring 5 are formed by bending a member (see FIG. 7) cut from a single plate material. And are integrally connected. That is, the fingertip side of the flat portion 1 along the ventral side of the thumb 9 is connected to the front ring 4 at the front ring fulcrum 7 on the nail side of the thumb 9 via the arm 3, and the finger base of the flat portion 1 The rear ring 5 is connected at the rear ring fulcrum 8 on the side.
At this time, the front ring 4 and the rear ring 5 are connected to the flat portion 1 on the center line of the thumb when viewed from the front.

In the embodiment shown in FIGS. 1 to 3, the main function of the front ring 4 and the rear ring 5 is not to tighten the thumb 9 strongly, but to closely contact the thumb 9 to make the positional relationship between the flat portion 1 and the thumb 9 constant. It is to keep. Therefore, although the front ring 4 is a belt-shaped member that is curved so as to cover the fingertip portion, it has an opening on the ventral side of the thumb 9 and has a flat, substantially C-shaped cross section. Moreover, the diameter thereof becomes slightly smaller toward the tip of the finger.
The rear ring 5 is formed so that a belt-shaped member connected to the finger base side of the flat portion 1 is curved and wound around the first joint of the thumb 9. Furthermore, in order to fit the warp of the tip of the thumb 9, there is an inclination from the base of the finger toward the tip of the finger (see FIG. 2). Unlike the front ring 4, the rear ring 5 goes around the thumb 9 and overlaps on the claw side to form a rear ring overlapping portion 6.

 1 to 3 showing an embodiment when the present invention is used as a thumb pick, a playing pick portion 2 is a portion integrally formed with a flat portion 1 so as to project from a side surface, and at least one portion is formed. Has been done. Further, since the playing projection 2 is integrally formed, the material is appropriately selected from materials suitable for playing picks such as resin, turtle shell, and metal.

 FIG. 4 shows an example in which a commercially available flattop 10 is mounted by sandwiching it between the flat portion 1 and the thumb 9 and used as a substitute for the playing pick portion 2 to use it as a thumb pick. It is a thing. At this time, since the playing pick portion 2 is not provided on the side surface of the flat portion 1, the flat portion 1 has the same size and shape as shown in FIGS. To do.

 When the playing pick portion 2 is provided, it can be used for both right-handed and left-handed persons by forming it on both sides of the thumb as shown in FIG. 1, but either one may be used. In addition, the shape of the playing pick part 2 can have various shapes as well as commercially available flat topics because there are few restrictions on modeling, such as a triangular shape, tear drop shape, circular shape, etc. A wide variety of playing styles can be supported by changing the direction and size of.

 As shown in FIG. 4, when the commercially available flat topic 10 is used, it is possible to provide some anti-slip on the thumb side surface of the flat portion 1.
