Finger pressure aid for stringed instruments

The present invention relates to a finger pressure assisting device for a stringed instrument, and more particularly to a finger pressure assisting device for avoiding pain caused by pressing a string by a finger press.

In an ideal situation, the closer the chord is to the melody, the better the timbre will be, and there is no need to use too much force (as shown in Figure 16). However, according to the ergonomic arrangement of the fingers, the ideal state of the chord finger position cannot be achieved. For example, as shown in Fig. 16A, the A chord 1 is farther away from the piano and needs to use a larger force to pop up normally. The tone, but it also causes the root cause of string pain.

It is known that there are a number of devices that can be used to help beginners of string instruments avoid the pain of stringing. For example, the inventor's new Taiwan patent M304737 provides a learning aid for guitars. In addition, as disclosed in U.S. Patent No. 2007/0034070, a teaching method and apparatus for chord-combined note positions corresponding to a stringed instrument are provided. A chord performance accessory and related method are disclosed, for example, in U.S. Patent No. US 2013/0239772.

The above publications are all ancillary devices provided for practicing the chord portion, and basically only some fixed notes and fingers of the local area are used to chord by means of auxiliary equipment. However, in addition to chords, cooked Playing guitars requires more notes and a wider range of fingers. Beginners still need to use their fingers to press the strings, and they cannot avoid the pain of pressing the strings.

The main object of the present invention is to provide a finger pressure assisting device for a stringed instrument, which will avoid the pain caused by the pressure string by the finger pressing plate, and is used to improve the disadvantages of the conventional stringed instrument.

In order to achieve the above and other objects, according to the present invention, a finger pressure assisting device for a stringed instrument includes a neck coupled to the body, a fingerboard disposed on the neck, and a plurality of laterally spaced apart a plucking of the fingerboard, and a plurality of strings extending along the length of the neck; wherein the acupressure auxiliary device comprises: a plurality of fingerboards respectively corresponding to the plurality of strings and along the strings An extension of the length of the string; an upper support frame, the suspension supports one end of the plurality of finger pressure plates, and is fixed to the upper end of the neck; the lower support frame supports the other end of the plurality of finger pressure plates and is fixed to The lower end of the neck or the body.

In other embodiments of the present invention, each of the through slots 144 may also be a dovetail slot 144B, as shown in FIG. 1B. However, the present invention allows the finger pressure plate to be closer to the strings by the design of the T-shaped groove 144A or the tail groove 144B, and the screw segment 11 of the finger pressing plate 10 is locked by the nut 110, except that the finger pressing plate 10 can be thereby used. Fixed to the lower support frame 14, the tightness of the finger pressure plate 10 can also be adjusted by the nut 110.

Furthermore, a plurality of ruled lines 102 are scribed on the top surface of each fingerboard 10, corresponding to a plurality of positions of the fingers 34 of the fingerboard 34, and the acupressure assisting device 1 is detachably mounted on The fingerboard 34 is mounted such that the strings 35 are located on the underside of the device; preferably, the width of each of the finger plates 10 is greater than the corresponding diameter of the strings 35 by at least 2 times the width.

Figures 3, 4, 4A and 5 show a longitudinal section, a cross-sectional view and a state of use of the components of the acupressure assisting device 1. According to the present invention, a plurality of ribs 101 of each of the fingerboards 10 are arranged, respectively corresponding to the plurality of chords 36, and are offset from each other but adjacent to each other, and each of the ribs 101 corresponds to each of the ribs 101. a slightly above position of a piano (As shown in Fig. 5), the tone can be improved by the fact that the closer the point of pressing the string 35 is to the piano 36, the better the tone can be obtained. However, in the present embodiment, the design of the rib 101 is relatively limited by the finger pressing, and the finger pressing portion is limited by the finger, and the design of the rib 101 of the embodiment cannot be as close as possible to the piano yoke 36. Therefore, you can get the perfect sound.

Moreover, in this embodiment, a tapered groove 1011 corresponding to the string 35 is formed on the pressing surface of each of the ribs 101 of each of the finger plates 10 (as shown in FIGS. 4 and 4A), and Each tapered groove 1011 includes an arcuate end 1012. In this way, the force applied by the user's fingertip to the string 35 through the finger pressing plate 10 can be more sure, and the finger pressing plate 10 does not slip off the string 35; and when the string 35 is shaken, by the tapered groove 1011 The design can indeed press the fixed string 35.

Figures 6 and 7 are used to illustrate the second embodiment of the fingerboard of the present invention. As shown in the figure, the top surface of each fingerboard 10' is a quasi-plane, and the plurality of fingerboards 10' are integrally formed, and the two ends are fixed ends, and are divided into plural numbers between the two ends by a plurality of slits 103. Finger plate unit 10' is convenient for production, assembly and fixing.

Figure 8 is a third embodiment of the finger press plate of the present invention. In this embodiment, in particular, the top surface of each finger press plate 10a' is formed into a convex surface; and Figure 9 is a finger press plate of the present invention. In the fourth embodiment, the difference between the embodiment is that the top surface of each finger pressing plate 10b' is rounded and concave, so that the user feels more accurate when pressing the string, and the force applied by the user's fingertip can be more accurate. The ground is conveyed to the strings 35.

Figure 10 shows an embodiment of the present invention providing a second upper support frame. As shown, the upper support frame 12' includes a pillow block 120. One end is a fixed end for fixing to an upper end of the neck (not shown), and the other end forms a protrusion 1202 which is convex and inclined toward the longitudinal direction of the string 35; the pillow block 120 corresponds to the plural a string 35 position, a plurality of longitudinal grooves 1201 are vertically downward from the top surface, and each of the strings 35 passes through each of the grooves 1201; and the top surface of the protrusion 1202 corresponds to the A plurality of longitudinal concave surfaces 1203 are disposed at a plurality of grooves 1201, and each concave surface 1203 is spanned on the left and right sides of each groove 1201 for supporting each of the finger pressing plates 10. In this way, each of the finger plates 10 can be more accurately corresponding to each of the strings 35.

Figure 11 is a view for explaining an embodiment of the present invention which provides a second lower support frame. As shown, the lower support frame 14' includes an upper clamp 140a, a lower clamp 140b, a pressure plate 140c, and a restraining portion 140d.
