Technical Field
[0001] The present application relates to the technical field of musical instrument assistants, and in particular to an auxiliary string-pressing device for guitar playing. Background Art
[0002] Guitar is a very common and mainstream musical instrument, which is widely used in the creation of various types of music. It is also a relatively affordable musical instrument. However, due to the small distance between adjacent strings, adjacent strings are often pressed by mistake during the process of learning to play chords, resulting in muffled sound. In addition, there are many chords. When beginners switch chords, they cannot remember or remember the chords accurately, which leads to the situation that the chords cannot be switched quickly and accurately. In addition, the direct contact between the strings and the fingers causes finger pain, which also reduces the interest of beginners. Therefore, an auxiliary device is born. The multiple pressing keys of the auxiliary device are pressed by fingers to drive the action of the pressing plate, so that the string pressing block set on the pressing plate contacts the strings to realize chord playing. The pressing plate in the initial auxiliary device is arranged in a flat shape (CN108538272B ), the number of chords that can be played after one installation is small, and then there are auxiliary devices in which the pressing plates are staggered along the thickness direction (CN217933134U, CN217955420U), which increase the number of chords that can be played after one installation, reduce the frequency of replacing the pressing plates, and make it more convenient to use. However, since the pressing keys in the existing auxiliary devices are relatively large in size, the pressing keys connected to the pressing plates on the lower layer need to avoid the pressing plates on the upper layer in order to be pressed. Since the pressing keys in the prior art are relatively large in size, in order to give the pressing keys connected to the pressing plates on the lower layer a certain pressure is required. The keys provide enough avoidance space, and the gap between the two pressing plates on the upper layer is very large. On the one hand, it greatly affects the distribution of the number of pressing plates on the upper layer, and thus the number of pressing plates that can be set is greatly limited, which in turn will greatly affect the number of chords that can be played after the auxiliary device is installed once; on the other hand, when the same string needs to be pressed at multiple frets, in order to avoid interference between the upper pressing plate and the pressing keys passing through the bottom or interference between the string pressing block connected to the upper pressing plate and the lower pressing plate, the pressing plate needs to be made into a special shape according to the distribution situation to meet the use requirements.
[0003] The auxiliary string pressing device of the prior art needs to have a certain thickness and width because the elastic string pressing arm's elasticity and rigidity need to be considered. Generally, only four elastic string pressing arms can be arranged on the width of the bracket seat. At the same time, the layout of the elastic string pressing arm needs to be considered. There needs to be enough space to accommodate the elastic string pressing arm and the keys on the elastic string pressing arm extending to the outer layer of the entire device. The elastic string pressing arm can only be stacked in two layers at most. Therefore, the keys that can be set on an auxiliary string pressing device are very limited. According to the current structure and reasonable layout, at most one auxiliary string pressing device can only be set with ten keys. This is obviously far from enough for string instruments with many chords. Fortunately, the number of commonly used chords for guitars is not large, but ten keys are still slightly insufficient. This requires the addition of an elastic string pressing arm. The original two-layer elastic string pressing arm setting will not accommodate the increased elastic string pressing arm, so it is necessary to increase the original two-layer elastic string pressing arm to three layers or more. At the same time, the number of elastic string-pressing arms extending from the bracket seat is greater, and the parts of the elastic string-pressing arms extending from the bracket seat are closely adjacent, so that the string-pressing lever connected to the key and the string-pressing block vertically set near the bracket seat position will be blocked by the closely adjacent elastic string-pressing arms. The installation form of the existing technology cannot solve the above technical problems. Utility Model Content
[0004] In view of this, the present application provides an auxiliary string-pressing device for guitar playing, which can use a thinner string-pressing lever to penetrate multiple stacked elastic string-pressing arms to reduce the space occupied by the pressing member, so as to solve the technical problem that the number of elastic string-pressing arms that can be installed is limited.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] An auxiliary string-pressing device for guitar playing comprises a support seat and a plurality of elastic string-pressing arms connected to the support seat at one end, the support seat has a connecting piece that can be detachably connected to the guitar, the elastic string-pressing arm is provided with a key and a string-pressing block, and further comprises at least one string-pressing operating rod connected to the key and / or the string-pressing block, the string-pressing operating rod is perpendicular to the support seat and passes through at least one elastic string-pressing arm, the corresponding elastic string-pressing arm is provided with an avoidance channel for the corresponding string-pressing operating rod to movably pass through, a reset structure is provided between the string-pressing operating rod and the support seat, and the avoidance channel is a channel composed of an avoidance hole arranged on the corresponding elastic string-pressing arm or a notch groove arranged on the edge of the corresponding elastic string-pressing arm.
[0007] Furthermore, the reset structure is an elastic string-pressing arm, one end of which is fixed on the bracket seat, and the other end of which is extended out, and the corresponding string-pressing operating rod is connected to the extended end of the elastic string-pressing arm.
[0008] Furthermore, a joystick fixing frame is also provided on the bracket seat, and the string-pressing joystick moves through the corresponding joystick fixing frame, and a reset structure is provided on the joystick fixing frame.
[0009] Furthermore, the joystick fixing frame is a gantry, the crossbeam of the gantry is located above the elastic string-pressing arm of the top layer, and the corresponding string-pressing joystick moves through the crossbeam.
[0010] Furthermore, when the string-pressing operating rod passes through the middle position of the corresponding elastic string-pressing arm, the avoidance channel is located at the middle position of the elastic string-pressing arm and forms a complete through hole.
[0011] Furthermore, when the string-pressing operating rod passes through two adjacent elastic string-pressing arms, the avoidance passage is a through hole formed by splicing the respective notches on the adjacent elastic string-pressing arms.
[0012] Furthermore, the avoidance hole and the notch groove are both provided with reinforcing ribs located on the surface of the corresponding elastic string-pressing arm and extending along the edge of the avoidance channel.
[0013] Furthermore, when the elastic string-pressing arm is used in combination with the string-pressing operating rod and the elastic string-pressing arm, a three-layer or four-layer structure can be formed.
[0014] Furthermore, the cross section of the string-pressing lever is in an elongated shape with a long length along the extending direction of the neck and a short length perpendicular to the extending direction of the neck.
[0015] Furthermore, the button and / or the string-pressing lever are both provided with a detachable cap, wherein the cap can be sleeved on the outside of the button and / or the string-pressing lever.
[0016] It can be seen from the above technical solution that the advantages of the utility model are:
[0017] 1. In the present application, a thinner string-pressing operating rod is used to pass through a plurality of stacked elastic string-pressing arms, and the layout influence of each layer of elastic string-pressing arms is reduced by occupying as little space as possible on each layer.

[0018] 2. The arrangement of the string-pressing lever in the present application has little influence on the layout of the elastic string-pressing arm, and the elastic string-pressing arm can be arranged in more layers.

DETAILED DESCRIPTION
[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.
[0037] refer to Figures 1 to 13 ,like Figures 1 to 10 As shown, this embodiment provides an auxiliary string-pressing device for guitar playing, including a bracket seat 1 and a plurality of elastic string-pressing pieces 2 arranged on the bracket seat 1, the bracket seat 1 has a connecting piece that can be detachably connected to the guitar 100, one end of the elastic string-pressing piece 2 is fixed on the bracket seat 1, the string-pressing part of the elastic string-pressing piece 2 is at least one elastic string-pressing arm 21 arranged flat, one elastic string-pressing arm 21 is provided with at least one key 23 and at least one string-pressing block 22, and the plurality of string-pressing blocks 22 can realize multi-point pressing of the strings at the same time, and the plurality of keys 23 on the elastic string-pressing arm 21 are arranged, and the distance between the plurality of keys 23 on different elastic string-pressing arms 21 used in combination can be adjusted, so that chord playing is more convenient. The auxiliary string-pressing device also includes at least one string-pressing lever 24 connected to the key and / or the string-pressing block. The string-pressing lever 24 is perpendicular to the bracket seat 1 and passes through at least one elastic string-pressing arm 21. The corresponding elastic string-pressing arm 21 is provided with an escape channel for the corresponding string-pressing lever 24 to move through. A reset structure 26 is provided between the string-pressing lever 24 and the bracket seat 1 to drive the string-pressing lever 24 to rise and reset.
[0038] Specifically, the key 23 of the present invention mainly functions to allow the left hand to find the pressing point of the corresponding elastic string-pressing arm 21 through touch and / or vision when playing. For the elastic string-pressing arm 21 located at the lower layer that is not exposed on the entire device surface, the key 23 needs to be connected to the elastic string-pressing arm 21 through the string-pressing lever 24, so that the key 23 can be exposed on the device surface, so that the finger can act on the elastic string-pressing arm 21 from the outside through the key 23. The cross section of the portion of the string-pressing lever 24 that is used to pass through the elastic string-pressing arm 21 is an elongated shape with a long length along the extension direction of the neck and a short length perpendicular to the extension direction of the neck, so that the portion is flat as a whole. The width of the string-pressing lever 24 is smaller than the width of the elastic string-pressing arm 21. Preferably, the string-pressing lever 24 is flat as a whole or one end that is used to pass through the elastic string-pressing arm 21 is flat. The size of the string-pressing block 22 connected to the string-pressing lever 24 is comparable to the size of the string-pressing block 22 directly connected to the elastic string-pressing arm 21, so as to avoid the reliability of string pressing during playing due to the smaller size of the string-pressing block 22 connected to the string-pressing lever 24. By setting the string-pressing lever 24 to occupy as little space as possible on each layer of the elastic string-pressing piece 2, the influence on the layout quantity of the elastic string-pressing arm 21 can be reduced. Figure 2 The elastic string pressing piece 2a, the elastic string pressing piece 2b, and the elastic string pressing piece 2c are stacked and installed. Figure 2 The elastic string-pressing pieces 2d and 2e are stacked together with the string-pressing operating rod 24. In a limited space, after one installation is completed, the more elastic string-pressing arms 21 there are, the more chords can be played, further reducing the frequency of disassembling and replacing the elastic string-pressing pieces 2. Moreover, since the elastic string-pressing arms 21 do not need to deliberately avoid the string-pressing operating rod 24, the strip structure of the extended section of the elastic string-pressing arms 21 directly connected to the bracket seat 1 has little effect, the structure is simple, and the processing is convenient. The stacked multi-layer elastic string-pressing pieces 2 are connected to the bracket seat 1 after being sequentially penetrated by a plurality of fixing bolts 4, so that the elastic string-pressing pieces 2 can be replaced as needed. When the elastic string-pressing pieces 2 are replaced, multiple elastic string-pressing arms 21 can be replaced at a time, making the replacement of the elastic string-pressing arms 21 simpler, so that the present application can be adapted to more chord playing. When in use, the string-pressing operating rod 24 performs a lifting movement in the corresponding avoidance channel under the action of the external pressing force and the reset structure 26 to press down or reset the corresponding string-pressing block 22.
[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the reset structure 26 is an elastic string-pressing arm 21, one end of which is fixed on the bracket seat 1, and the other end of the elastic string-pressing arm 21 is extended, and the corresponding string-pressing operating rod 24 / the corresponding string-pressing block 22 is connected to the extended end of the elastic string-pressing arm 21.
[0040] Specifically, one end of the elastic string-pressing arm 21 can be connected to the bracket seat 1 through a corresponding fixing bolt 4, or the elastic string-pressing arm 21 can be fixed by passing the fixing bolt 4 for fixing the elastic string-pressing piece 2 through the corresponding elastic string-pressing arm 21, or the elastic string-pressing arm 21 can be fixed by clamping the elastic string-pressing arm 21 with two connected elastic string-pressing pieces 2. For the elastic string-pressing arm 21 located at the upper layer, since it is at a certain distance from the guitar strings that need to be pressed, the string-pressing block 22 needs to be connected to the elastic string-pressing arm 21 through the string-pressing operating rod 24, so that the string-pressing block 22 can be close to the strings that need to be pressed. Figure 4 , Figure 5 , Figure 6 As shown, for the elastic string pressing arm 21 located at the bottom layer, a string pressing lever 24 needs to be connected to the button 23, and the avoidance channel is all located above the elastic string pressing arm 21; Figure 7 and Figure 8 As shown, for the elastic string pressing arm 21 located at the top layer, a string pressing lever 24 needs to be connected to the string pressing block 22, and the avoidance channel is all located below the elastic string pressing arm 21; Figure 2 , Fig. 9 , Fig.10 As shown, for a device with at least three layers of elastic string-pressing arms 21, the elastic string-pressing arms 21 located in the middle layer need a string-pressing lever 24 connected to the string-pressing block 22, and a string-pressing lever 24 connected to the key 23. Here, the string-pressing lever 24 connected to the string-pressing block 22 and the string-pressing lever 24 connected to the key 23 are generally located at the same axial position, and the avoidance channels are distributed on the upper and lower sides of the elastic string-pressing arm 21, wherein the string-pressing block 22 can be in the shape of a bar column or designed to be in an inverted L shape or a multi-tooth shape formed by splicing a plurality of different shapes as required.
[0041] The reset structure 26 can also be a floating frame connected to the string-pressing lever 24 and elastically floated on the support seat 1 using a spring.
[0042] Specifically, the floating frame is connected to the guide member arranged on the bracket seat 1 in a lifting and sliding manner, and the spring sleeved on the guide member presses against the floating frame so that the floating frame can automatically rise and reset. This structure is mostly used when the floating frame is located above all the elastic string-pressing arms 21. Since the string-pressing operating rod 24 will not deflect during the lifting process, the size of the avoidance channel can be basically the same as that of the string-pressing operating rod 24, thereby minimizing the influence of the avoidance channel on the strength of the elastic string-pressing arm 21.
[0043] As an alternative, in a structure in which a joystick fixing frame cooperates with a string-pressing joystick 24 and a return spring is provided, the string-pressing joystick 24 is not connected to the elastic string-pressing arm 21 , and its two ends are connected to a button 23 and a string-pressing block 22 .
[0044] In a specific implementation, a joystick fixing frame is disposed on the bracket seat 1 , and the string-pressing joystick 24 movably passes through the corresponding joystick fixing frame. The joystick fixing frame is provided with a reset structure 26 for driving the string-pressing joystick 24 to rise and reset.
[0045] In the embodiment of the present application, the reset structure 26 disposed on the joystick fixing frame is a reset spring or a disc spring disposed between the corresponding string-pressing joystick 24 and the bracket seat 1 .
[0046] A structure of the joystick fixing frame is: the joystick fixing frame is fixed integrally with the bracket seat 1, the joystick fixing frame is in the shape of a plate or a strip, when the joystick fixing frame is in the shape of a plate, the joystick fixing frame is parallel to the strings, and when the joystick fixing frame is located at the bottom layer or the top layer, the thickness of the present application is minimized, the string-pressing joystick 24 is slidably matched with the through hole provided on the joystick fixing frame, the reset structure 26 is a reset spring sleeved on the string-pressing joystick 24, and the reset spring is limited by providing a limiting boss capable of resisting the reset spring on the string-pressing joystick 24 or by installing an end plate capable of resisting the reset spring on the top of the string-pressing joystick 24.
[0047] Another structure of the joystick fixing frame is: Fig.11 , Fig.12 As shown, the joystick fixing frame is a gantry 3, and the crossbeam of the gantry 3 is located above the elastic string-pressing sheet 2 on the uppermost layer. The corresponding string-pressing joystick 24 moves through the crossbeam. The installation form of the reset structure 26 is the same as the above description. The use of the gantry 3 makes the position of the string-pressing joystick 24 more flexible, and the structure of the present application is simpler.
[0048] In the embodiment of the present application, the avoidance channel is a channel composed of an avoidance hole 211 provided on the corresponding elastic string-pressing arm 21 or at least one notch groove 213 provided on the edge of the corresponding elastic string-pressing arm 21 .
[0049] Specifically, when the string-pressing operating rod 24 passes through a plurality of the avoidance passages, a plurality of avoidance holes 211 are coaxially arranged, and the notch groove 213 is mounted in an engaging manner with the string-pressing operating rod 24 , so that the structure of the string-pressing operating rod 24 is simple.
[0050] The avoidance channel can also be composed of opposite notches 213 arranged on two adjacent elastic string-pressing arms 21, so that the space occupied by the string-pressing operating rod 24 is dispersed on the two elastic string-pressing arms 21, thereby reducing the influence on the strength of the elastic string-pressing arms 21. If necessary, Figure 2 As shown in the elastic string-pressing piece 2b, the corresponding elastic string-pressing arm 21 may also be provided with the avoidance hole 211 or the notch groove 213.
[0051] In the embodiment of the present application, preferably, when the string-pressing lever 24 passes through the middle position of the corresponding elastic string-pressing arm 21 , the avoidance channel is located in the middle position of the elastic string-pressing arm 21 and forms a complete through hole, which is the avoidance hole 211 .
[0052] In the embodiment of the present application, preferably, when the string-pressing lever 24 passes through two adjacent elastic string-pressing arms 21 , the avoidance passage is a through hole formed by splicing the respective notches 213 provided on the adjacent elastic string-pressing arms 21 .
[0053] In the embodiment of the present application, when the elastic string-pressing arm 21 is used in combination with the string-pressing lever 24 , a three-layer or four-layer structure can be formed to arrange more string-pressing blocks 22 .
[0054] Since the setting of the avoidance hole 211 and / or the notch groove 213 will reduce the effective connection width at the corresponding position of the elastic string-pressing arm 21, thereby reducing the strength of the elastic string-pressing arm 21, in order to improve the strength of the elastic string-pressing arm 21, the avoidance hole 211 and the notch groove 213 are both provided with reinforcing ribs 212 located on the surface of the corresponding elastic string-pressing arm 21 and extending along the edge of the avoidance channel.
[0055] Specifically, when the elastic string-pressing arm 21 has one or more notches 213, the arrangement of the reinforcing rib 212 can refer to Figure 2The reinforcing ribs 212 on the elastic string pressing piece 2b are reinforced along the edge of the notch groove 213 or multiple reinforcements are achieved at the same time by using irregular curved strip ribs. When the elastic string pressing arm 21 has an avoidance hole 211, the arrangement of the reinforcing ribs 212 can refer to Figure 3 The reinforcing ribs 212 are arranged on the elastic string-pressing piece 2, and the reinforcing ribs 212 can be ring-shaped or multi-point surrounding.
[0056] The different elastic string-pressing arms 21 of the present application realize unidirectional association through the linkage arm 231. For unidirectional association, Chinese patent CN 108538272B has a detailed description. In this embodiment, Figure 3 , Figure 6 and Figure 7 As shown, at least one of the buttons 23 or at least one of the elastic string-pressing arms 21 is provided with a linkage arm 231, and the linkage arm 231 is abutted against the top or bottom of at least one corresponding elastic string-pressing arm 21. When the linkage arm 231 is abutted against the top of the corresponding elastic string-pressing arm 21, pressing the button 23 / elastic string-pressing arm 21 with the linkage arm 231 can drive other associated elastic string-pressing arms 21 to be pressed down to play the strings; when the linkage arm 231 is abutted against the bottom of the corresponding elastic string-pressing arm 21, pressing the associated elastic string-pressing arm 21 to play the strings will drive the elastic string-pressing arm 21 with the linkage arm 231 to be pressed down at the same time to play the strings.
[0057] In the embodiments of the present application, Figure 7 and Figure 8 As shown, a detachable cap 28 is provided on the button 23 and / or the string-pressing lever 24. Since the string-pressing lever 24 has a small operating size and is not easy to press, the provision of the cap 28 can increase the finger contact area of the string-pressing lever 24 to prevent accurate pressing, and the cap 28 can be printed or engraved with corresponding chord numbers to make playing more convenient.
[0058] Specifically, the cap 28 is buckled on the button 23, and the top of the string-pressing lever 24 is detachably sleeved with a sleeve 27 that can be snapped together with the button 23, so that the cap 28 can be uniformly set and interchangeably used. As for the elastic string-pressing arm 21 located at the uppermost layer on the front side, the button 23 thereon can be protruding or not, and only the finger touch at the pressing point can be different from that of the rest of the elastic string-pressing arm 21. At this time, the button 23 thereon can be a patch or an embedment made of different materials, or have different surface textures, or be in the form of grooves, etc., and can even be printed with specific symbols, patterns, and colors at the position where it needs to be pressed. When the button 23 does not need to be protruding, the cap 28 does not need to be installed.
[0059] like Fig.13 As shown, the connecting member provided on the bracket seat 1 and capable of being detachably connected to the guitar 100 is a plurality of clamping members 12 which are threadedly mounted on the frame 11 of the bracket seat 1 and can abut against the side of the guitar 100. The fixed installation of the present application is achieved by screwing the clamping members 12 so that the clamping members 12 abut against the guitar 100.
[0060] In actual use, the connecting member can also be a strip elastic band or an elastic clamping arm mechanism that engages with the neck of the guitar.
[0061] In the embodiment of the present application, the support seat 1 also has a plurality of adjusting bolts 13 which are threadedly mounted and can abut against the front of the guitar 100. The adjusting bolts 13 are used to adjust the gap between the string pressing block 22 and the strings, so that the string pressing block 22 can contact or separate faster when pressed.
[0062] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
