Problems solved by technology

However, in this scheme, the main control lever and the auxiliary control lever each have a rotating shaft, and the pressure of pressing the key of the main control lever with a finger is pressed down to the strings after passing through the secondary transmission, which is easily caused by friction and other reasons during the transmission process. Pressure loss, plus a main control lever has multiple branch levers, it still takes a lot of force when the finger presses the button
Moreover, when a certain grade of a string corresponds to multiple chords, that is, when multiple main control rods need to be able to drive a secondary control rod, in order to avoid mutual interference, they need to be staggered in the horizontal direction. here comes the difficulty

Embodiment Construction

[0041] combine figure 2 , image 3, in order to clearly show the internal structure of the guitar chord fingering device 100, the housing is omitted. A rotating shaft 103 is installed on the first column 101 and the second column 102 . One end of the first rotating arm 104 is rotatably connected to the rotating shaft 103 , the other end is rotatably connected to the L-shaped first key rod 108 , and is connected to the first pressing rod 106 at a middle position between the two ends. More specifically, in this embodiment, the first rotating arm 104 is also rotationally connected to the first pressing rod 106 . The other end of the first key rod 108 opposite to the connecting end of the first rotating arm 104 has a first button 110, and from Figure 6 It can be seen more clearly in , the first key 110 protrudes from the side of the casing, in image 3 , Figure 6 As can be seen in the figure, both the columns 101 , 102 and the rotating shaft 103 can be regarded as a part o...

Abstract

The invention provides a guitar chord fingering device. The device comprises: a housing; L-shaped key rods provide with keys extending from one side of the housing; pressing rods, the lower ends of which are provided with pressing boards, wherein branch pressing rods are arranged below the pressing boards according to a chord fingering score; rotating arms, one ends of which are rotationally connected to the housing, the other ends of which are rotationally connected to the L-shaped key rods, and the middle parts of which are connected to the pressing rods; and return springs, which enable the branch pressing rods to press strings when the keys are pressed and the rotating arms rotate to press the pressing rods, and enable the rotating arms return when the keys are relieved. The guitar chord fingering device makes a player comfortable and convenient when playing chord.

Description

technical field [0001] The invention relates to the field of guitar accessories, in particular to a guitar chord fingering device. Background technique [0002] Guitar is a very popular instrument around the world, and when playing, it is often necessary to play chords. However, if figure 1 As shown, the guitar chord fingering spectrum is very complicated. There are nearly 360 kinds of fingerings on the chord fingering spectrum from A to G, and there are more than a dozen commonly used ones, and in each chord fingering, different fingers are required to press different keys. Different grades on the strings, and guitars generally have 12 grades or 14 grades, which need to be changed when playing, which brings great difficulties to guitarists, especially beginners. Moreover, frequent pressing of the strings can cause pain in the fingers. [0003] In order to make it more convenient and more comfortable for the guitarist to play chords, the improvement scheme taken by techni...
