Description

Technical Field

[0001] This invention relates to the field of piano teaching technology, and in particular to a fingering training device for piano teaching. Background Technology

[0002] The piano is a keyboard instrument in Western classical music and is known as the "king of instruments".

[0003] The existing piano keys are arranged sequentially on the upper part of the piano body. When beginners play the piano, they often cannot press a single key accurately because their fingers are not flexible enough. Instead, they tend to press two adjacent keys at the same time with one finger, resulting in syllable errors. Summary of the Invention

[0004] The purpose of this invention is to provide a fingering training device for piano teaching, so as to solve the technical problems existing in the prior art.

[0005] To address the aforementioned technical problems, this invention provides a fingering training device for piano teaching, comprising a piano body, keys, and limiting components.

[0006] The piano keys are provided in several groups, and several of the piano keys are embedded in the upper part of the piano body and arranged in sequence.

[0007] Several sets of limiting components are provided, each corresponding to a piano key, and these limiting components are disposed inside the piano housing.

[0008] When two adjacent sets of piano keys are pressed simultaneously, the limiting component is used to simultaneously limit the two adjacent sets of piano keys to prevent them from moving into the piano housing at the same time.

[0009] As a further improvement of the present invention: the lower parts of several of the piano keys extend into the interior of the piano body, and each group of piano keys has inclined surfaces on both sides of its lower part; the several limiting components are correspondingly disposed between the several piano keys.

[0010] The limiting assembly includes a limiting plate, a rotating sleeve, and a support assembly.

[0011] The support assembly provides rotational support for the rotating sleeve, allowing the rotating sleeve to reciprocate along the support assembly. The rotating sleeve is positioned between two adjacent sets of piano keys.

[0012] The limiting plate is provided in two sets, and the two sets of limiting plates are fixedly installed on the outer wall of the rotating sleeve. The two sets of limiting plates are distributed in a figure-eight shape. The end of one set of limiting plates away from the rotating sleeve abuts against the inclined surface of one set of piano keys, and the end of the other set of limiting plates away from the rotating sleeve abuts against the inclined surface of the other set of piano keys.

[0013] As a further improvement of the present invention: the support assembly includes a support shaft, a support vertical plate, and a base plate.

[0014] The bottom plate is connected to the inner wall of the piano box at one end. The supporting vertical plate is fixedly installed on the upper part of the bottom plate. The supporting shaft is fixedly installed on one side of the supporting vertical plate. The rotating sleeve is rotatably sleeved on the outside of the supporting shaft.

[0015] As a further improvement of the present invention: a supporting horizontal plate is fixedly provided on one side of the supporting vertical plate, and the supporting horizontal plate extends to below the supporting shaft.

[0016] An elastic reset member is connected to the upper part of the support cross plate. The end of the elastic reset member away from the support cross plate is connected to the rotating sleeve outside the support shaft. The elastic reset member is used to provide elastic tension to the rotating sleeve.

[0017] As a further improvement of the present invention: a locking component is provided on the outer wall of the piano case, one end of the base plate is slidably engaged with the inner wall of the piano case, and the other end is connected to the locking component.

[0018] As a further improvement of the present invention: the side wall of the piano housing is provided with vertically distributed sliding grooves.

[0019] The locking assembly includes a locking nut and a locking screw.

[0020] One end of the locking screw is connected to one end of the base plate, and the other end extends from the slide groove to the outside of the piano body and is threaded into the locking nut.

[0021] As a further improvement of the present invention: vertically distributed guide rails are fixedly installed on the inner wall of the piano box, and a guide rail groove adapted to the guide rails is opened at one end of the base plate.

[0022] By adopting the above technical solution, the present invention has the following beneficial effects:

[0023] In this embodiment of the invention, when beginners play the piano, they often cannot accurately press a single key due to insufficient finger dexterity. Instead, they tend to press two adjacent sets of keys simultaneously with one finger, resulting in syllable errors. Therefore, this invention, through the setting of several limiting components, ensures that when a beginner presses two adjacent sets of keys simultaneously with one finger, the corresponding limiting components can limit the movement of those two sets of keys, thereby preventing them from moving into the piano body. Beginners, by observing this inability to press the keys, conclude that their fingering is inaccurate. Based on this conclusion, through long-term practice, beginners can achieve the goal of fingering training. Compared to existing technologies, this invention restricts the movement of two adjacent sets of keys when they are pressed simultaneously, achieving fingering training for beginners through this movement restriction effect, and has the advantage of better training results.

[0033] The present invention will be further explained below with reference to specific embodiments.

[0034] Please see Figure 1 This embodiment provides a fingering training device for piano teaching, including a piano body 10, piano keys 20, and limiting components 30. The piano keys 20 are provided in several groups, and several groups of piano keys 20 are embedded in the upper part of the piano body 10 and arranged in sequence. Several groups of limiting components 30 are provided in one-to-one correspondence with the piano keys 20. Several groups of limiting components 30 are disposed inside the piano body 10. When two adjacent groups of piano keys 20 are pressed at the same time, the limiting components 30 are used to simultaneously limit the two adjacent groups of piano keys 20 to prevent the two adjacent groups of piano keys 20 from moving into the piano body 10 at the same time.

[0035] When beginners play the piano, they often cannot accurately press a single key 20 due to insufficient finger dexterity. Instead, they tend to press two adjacent sets of keys 20 with one finger at the same time, resulting in syllable errors. Therefore, this invention, through the setting of several limiting components 30, enables the corresponding limiting components 30 to limit the two adjacent sets of keys 20 when a beginner presses two adjacent sets of keys 20 at the same time, thereby preventing the two adjacent sets of keys 20 from moving into the piano body 10. By observing this inability to press the keys 20, beginners can conclude that their fingering is inaccurate. Based on this conclusion, beginners can achieve the goal of fingering training through long-term practice.

[0036] Please see Figure 2 In one embodiment, the lower parts of several piano keys 20 extend into the interior of the piano housing 10. Each set of piano keys 20 has inclined surfaces 201 on both sides of its lower part. Several limiting components 30 are correspondingly disposed between the several piano keys 20. Each limiting component 30 includes a limiting plate 301, a rotating sleeve 302, and a support component. The support component provides rotational support for the rotating sleeve 302, allowing the rotating sleeve 302 to reciprocate along the support component. 302 is disposed between two adjacent sets of piano keys 20. There are two sets of limiting plates 301. The two sets of limiting plates 301 are fixedly disposed on the outer wall of the rotating sleeve 302. The two sets of limiting plates 301 are distributed in a figure-eight shape. One end of the limiting plate 301 away from the rotating sleeve 302 abuts against the inclined surface 201 on one side of one set of piano keys 20. The other end of the limiting plate 301 away from the rotating sleeve 302 abuts against the inclined surface 201 on one side of the other set of piano keys 20.

[0037] When a beginner pianist presses two adjacent sets of keys 20 simultaneously with one finger, the pressure applied by the finger is transmitted to two sets of limiting plates 301, and then from the two sets of limiting plates 301 to the support assembly. The support assembly cancels out the pressure from the two sets of keys, and the rotating sleeve 302 cannot rotate relative to the support assembly. Therefore, the two adjacent sets of keys 20 cannot move into the piano body 10 under pressure. Conversely, when a beginner pianist presses only one set of keys 20 with one finger, the pressure applied by the finger is transmitted to the corresponding set of limiting plates 301. This set of limiting plates 301 then drives the rotating sleeve 302 to rotate relative to the support assembly. The other set of limiting plates 301 rotates synchronously with the rotating sleeve 302 and separates from the corresponding key 20. Therefore, the set of keys 20 can move into the piano body 10.

[0038] Please see Figure 2In one embodiment, the support assembly includes a support shaft 303, a support vertical plate 304, and a base plate 307. The end of the base plate 307 is connected to the inner wall of the piano housing 20. The support vertical plate 304 is fixedly disposed on the upper part of the base plate 307. The support shaft 303 is fixedly disposed on one side of the support vertical plate 304. The rotating sleeve 302 is rotatably sleeved on the outside of the support shaft 303.

[0039] The rotating sleeve 302 is provided with rotational support by the support shaft 303. When two adjacent sets of keys 20 are pressed at the same time, the pressure is transmitted through the two sets of keys 20 to the two sets of limiting plates 301, and then through the two sets of limiting plates 301 and the rotating sleeve 302 to the support shaft 303. Finally, the pressure is gathered on the support shaft 303 into a vertically downward resultant force and then canceled out, so that the two adjacent sets of keys 20 cannot move into the piano body 10 when they are pressed. When only one set of keys 20 is pressed, the pressure is transmitted through the pressed key 20 to the corresponding limiting plate 301, and then through the limiting plate 301 and the rotating sleeve 302 to the support shaft 303 at an angle, thereby causing the rotating sleeve 302 to rotate relative to the support shaft 303, and the set of keys 20 moves into the piano body 10 accordingly.

[0040] Please see Figure 2 In one embodiment, a support horizontal plate 306 is fixedly provided on one side of the support vertical plate 304. The support horizontal plate 306 extends to the lower part of the support shaft 303. An elastic reset member 305 is connected to the upper part of the support horizontal plate 306. One end of the elastic reset member 305 away from the support horizontal plate 306 is connected to the rotating sleeve 302 outside the support shaft 303. The elastic reset member 305 is used to provide elastic tension to the rotating sleeve 302.

[0041] When a finger presses a set of keys 20, causing the set of keys 20 to move into the piano body 10, the rotating sleeve 302 rotates relative to the support shaft 303, and the elastic reset member 305 is stretched and bent. When the finger releases the set of keys 20, the set of keys 20 rebounds, and at the same time, the elastic reset member 305 pulls the rotating sleeve 302 to rotate in the opposite direction relative to the support shaft 303, thereby causing the two sets of limiting plates 301 to rotate in the opposite direction, realizing the reset of the two sets of limiting plates 301, and thus continuing to limit the adjacent two sets of keys 20.

[0042] In one embodiment, the elastic reset member 305 may be a spring or a metal sheet, and there is no limitation on this.

[0043] Please see Figure 1 and Figure 2In one embodiment, a locking component 40 is provided on the outer wall of the piano housing 10, and one end of the base plate 307 is slidably engaged with the inner wall of the piano housing 10, while the other end is connected to the locking component 40.

[0044] When a piano beginner is practicing, the locking assembly 40 locks the base plate 307 in a certain position inside the piano body 10, so that the two sets of limiting plates 301 are located between two adjacent sets of keys 20 and abut against the inclined surfaces 201 of the two adjacent sets of keys 20, thereby limiting the two adjacent sets of keys 20. After the piano beginner has practiced for a period of time and can accurately press a single key 20, the locking assembly 40 can release the locking state of the base plate 307. At this time, the base plate 307 can be pushed down, thereby causing the two sets of limiting plates 301 to move down, so that the two sets of limiting plates 301 separate from the inclined surfaces 201 of the two adjacent sets of keys 20, thereby releasing the limiting state of the two adjacent sets of keys 20. This avoids repeated contact between the keys 20 and the limiting plates 301 during the pressing process, which would lead to accelerated wear and thus extend the service life of the keys 20.

[0045] Please see Figure 3 In one embodiment, the side wall of the piano housing 10 is provided with vertically distributed sliding grooves 102, and the locking assembly 40 includes a locking nut 401 and a locking screw 402. One end of the locking screw 402 is connected to one end of the base plate 307, and the other end extends from the sliding groove 102 to the outside of the piano housing 10 and is threadedly engaged with the locking nut 401.

[0046] When a piano beginner is practicing, the locking nut 401 is tightened to lock the locking screw 402 in a certain position inside the slide groove 102. This causes the two sets of limiting plates 301 to be located between two adjacent sets of keys 20 and to abut against the inclined surfaces 201 of the two adjacent sets of keys 20, thus limiting the movement of the two adjacent sets of keys 20. After the beginner has practiced for a period of time and can accurately press a single key 20, the locking nut 401 can be turned to release the locking screw 402. At this time, the locking screw 402 can be pushed down, and it slides down along the inside of the slide groove 102, thereby causing the base plate 307 to move down along the inside of the piano body 10. This causes the two sets of limiting plates 301 to separate from the inclined surfaces 201 of the two adjacent sets of keys 20, thus releasing the limiting state of the two adjacent sets of keys 20.

[0047] Please see Figure 4 In one embodiment, vertically distributed guide rails 103 are fixedly provided on the inner wall of the piano housing 10, and a guide rail groove (not shown in the figure) adapted to the guide rails 103 is opened at one end of the base plate 307.

[0048] Please see Figure 1In one embodiment, a support plate 101 is fixedly provided at the bottom of the piano case 10.

[0049] In this embodiment of the invention, when piano beginners play the piano, they often cannot accurately press a single key 20 due to insufficient finger dexterity. Instead, they tend to press two adjacent sets of keys 20 simultaneously with one finger, resulting in syllable errors. Therefore, this invention, through the setting of several limiting components 30, enables the corresponding limiting components 30 to limit the two adjacent sets of keys 20 when a piano beginner presses two adjacent sets of keys 20 simultaneously with one finger, thereby preventing the two adjacent sets of keys 20 from moving into the piano body 10. Piano beginners can conclude from this inability to press the keys 20 that their fingering is inaccurate. Based on this conclusion, piano beginners can achieve the purpose of fingering training through long-term practice. Compared with the prior art, when two adjacent sets of keys 20 are pressed at the same time, the movement of the two sets of keys 20 can be restricted. Through this movement restriction, the fingering training of piano beginners can be achieved, which has the advantage of good training effect.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
