Description

[Technical Field]

[0001] The present invention relates to a piano finger training device and practice method, and more particularly to a practice device that allows players to freely control the finger movement when playing the piano and the strength with which the keys are struck, and relates to a technology for a piano finger training device and practice method that is easy to carry and can be used for practice anywhere where there is no sound similar to the shape of a piano keyboard. [Background technology]

[0002] The piano is one of the most representative musical instruments. It is particularly widespread, and is a popular extracurricular activity, with people attending piano lessons from a young age. However, for those who are not used to playing the piano, the strength of the fingers is surprisingly low, and it is difficult to play, not only for young children but also for adults, without repeated practice. In addition, young children have small hands, making it difficult for them to reach octaves, and they also need to practice stretching their hands as far as they can, so there is a demand for equipment that allows them to practice easily anywhere.

[0003] Furthermore, to play beautiful piano tones, the optimal fingering technique is determined by the flow of the sound. Practicing this correct fingering technique is also necessary for playing the piano well. Another important aspect is being able to freely control the dynamics of the sound. Music requires the skill to freely control the dynamics of the sound, such as playing piano, pianissimo, mezzo forte, forte, crescendo, decrescendo, etc., by gradually increasing the volume and gradually decreasing the volume. Mastering these techniques is undoubtedly a challenge for young children, and steady, repeated practice is essential to overcome them.

[0004] However, while repeated practice is necessary, various constraints, such as location and time, may apply depending on the home environment and housing situation. For example, practicing early in the morning or late at night may be impossible due to concerns about disturbing neighbors. Furthermore, practice time is often limited, especially in households with students preparing for exams, as it may disturb the studies of family members, especially siblings. Therefore, there is a need for a device that allows easy piano practice even without producing sound. Such practice devices have been developed in the past. However, these devices have been bulky and difficult to store and carry, making them difficult to practice easily. Therefore, there is a need for a compact, smart, and portable piano practice device.

[0005] In light of this problem, various technical proposals have been made. The title of the invention is "Practice aid for keyboard instruments and practice aid set," and the problem to be solved is "to provide a practice aid for keyboard instruments and a practice aid set for keyboard instruments that enables not only instructors but also students to confirm the correct positioning of fingers on the keyboard and to play beautiful sounds," and the specific solution is described as "The practice aid 2 for keyboard instruments is a mirror-finish resin plate-like body with semicircular corners and a roughly rectangular shape in plan view, with a thickness (t) of 1.0 mm, a height (h) of 9.3 mm, and a width (w) of 17.3 mm, which is removably attached to the inside of the fallboard 1, and stickers 4 are detachably affixed to each key 3 as markers to ensure the appropriate position according to the length of the student's fingers." However, while these technologies share the common problem of being practice aids that make it easier to teach correct finger placement, etc., the solution is for the student and the instructor to stick stickers on the piano keys and use them as markers for practice, taking into account the length of the fingers, etc. However, the present invention uses a device that resembles part of the keyboard, allowing practice of correct finger placement and the strength of finger strikes even in places where there is no piano, and so the solution is different.

[0006] The title of the invention is a "piano practice tool," and the problem to be solved is "to provide a piano practice tool that allows training to keep the base of the thumb flexible and to move the first and second joints of the thumb in a bent position in order to facilitate the thumb passing through the piano, which is necessary for playing the piano." The specific solution is described as "piano practice tool A equipped with knob 2 that can be turned while being pinched with the thumb and the opposing fingers, and knob 2 has a diameter wide enough that the thumb can be inserted between the tips of the fingers with the tip of the thumb bent inward. Piano practice tool A has a cylindrical body 1, and attached to the center of cylinder 1 are string 3 and weight 4 that are wound up by rotating cylinder 1 with the thumb and the other fingers. Furthermore, a knock mechanism is incorporated into cylinder 1, and the tip button of the knock mechanism protrudes from the central axis of knob 1, and is configured to produce a sound when the button is pressed." However, this technology has something in common with the present invention in that it allows training even in places where there is no piano, as long as there is the equipment, but it is a training device that is specialized for the thumb crossing required for piano playing, and it cannot be expected to perform all finger movements and training as with the present invention.

[0007] The invention is titled "Piano Practice Tool," and the specific solution is "a piano practice tool comprising a number of keys pivotally supported at their rear ends between raised portions on both sides of a frame, with an elastic body interposed between the frame and the bottom so that they resiliently move when finger pressure is applied to the front end, and the keys are held horizontally." This technology uses horizontal rods at the top of the keys to restrict their upward movement. Therefore, the raised portions supporting the horizontal rods are located at least on the left and right, which protrude from the keys, making them unstylish and interfering when connecting them. In contrast, the present invention differs in that it is possible to eliminate any protruding portions from the top, bottom, left, right, or front and back of the keyboard. The advantage of this difference is that the absence of protruding portions when carrying the tool makes it easy to store in a bag, etc., like a book or notebook.

[0008] The title of the invention is "Performance practice device, keyboard instrument, and fingering practice device," and the object to be solved is "to provide a performance practice device, keyboard instrument, and fingering practice device that allows even a beginner who has just started practicing playing a keyboard instrument to easily play or practice playing." The specific solution is described as "The performance practice device of the present invention comprises: storage means for storing music piece data including a plurality of keys corresponding to any one of the fingers of each hand and fingering data for specifying fingering; control means for reading and outputting the music piece data stored by the storage means; detection means for detecting a pressed key from among the plurality of keys; and musical sound signal generation means for generating and outputting a musical sound signal in accordance with the performance data in the music piece data output by the control means when a predetermined condition is met between the key corresponding to the finger specified by the fingering data in the music piece data output by the control means and the key detected by the detection means." The technology in question is limited to practicing only with the existing keyboard because frames are present on both sides of the keyboard, but the present invention has the feature of being able to connect multiple practice tools without the need for a frame, and has a different effect from the present invention.

FIG. [Figure 5] 1 is a diagram illustrating a connected state of the piano training apparatus according to the present invention; FIG. DETAILED DESCRIPTION OF THE INVENTION

[0024] The piano training device of the present invention comprises a bottom plate 10, a plurality of keys 20, support shafts 30, and elastic members 50. The support shafts 30 are sandwiched between the bottom plate end 11 of the bottom plate 10 and the key end 21 of the keys 20. The support shafts 30 rotatably support the keys 20 via hinges 40 provided for each key 20 and abut against the key end 21 to restrict the movement. The elastic members 50 are coil springs 53 provided between the bottom plate 10 and the keys 20 at predetermined locations, and are held by a retaining plate 54 provided on the top surface of the bottom plate 10. The following description will be made with reference to the drawings. However, the shape and configuration of the device are not limited to those shown in the drawings, and modifications can be made within the scope of the effects achieved by the creation of the technical concept of the present invention.

[0025] FIG. 1 is a diagram illustrating the basic configuration of the piano training device according to the present invention, showing the relationship between the bottom plate 10, keyboard 20, support shaft 30, and elastic member 50.

[0026] The piano training device 1 has a bottom plate 10, a plurality of keys 20, a support shaft 30, and an elastic member 50, with the support shaft 30 sandwiched between the bottom plate end 11 of the bottom plate 10 and the key end 21 of the keys 20, the support shaft 30 supporting the keys 20 so that they can rotate freely via hinges 40, and abutting against the ends of the keys 20 to restrict their movement, and the elastic member 50 is provided between the bottom plate 10 and predetermined locations of the keys 20.

[0027] FIG. 2 shows a front view, a side view, and a plan view illustrating the basic configuration of the piano training device according to the present invention. FIG. 2(a) is a plan view, FIG. 2(b) is a front view, FIG. 2(c) is a side view, and FIG. 2(d) is a cross-sectional view taken along the line A-A from the side. As shown in FIG. 2(a), the piano training device 1 according to the present invention has no protruding parts from the keyboard 20 when viewed from above, and when connected, it can be arranged in a configuration similar to the proper arrangement of the keys. Therefore, when connected by protruding half the amount of the gap between the keys to the side, it can be arranged in the same configuration as the white keys of a piano. Also, FIGS. 2(b) and 2(c) show the configuration of the piano training device 1 according to the present invention. The embodiment shown in FIG. 2(d) shows an example in which a coil spring 53 is used as the elastic member. A retaining plate 54 may be provided to provide key grooves 51 and bottom grooves 52 to hold the coil spring 53 above and below to prevent it from coming off when the keys are struck. Each of the components will be described in detail below.

[0028] Piano practice method 2 is a method for practicing efficiently using piano training device 1.

[0029] The bottom plate 10 is a base that serves as the base of the piano training device 1.

[0030] The bottom plate end 11 is a portion of the bottom plate 10 to which the support shaft 30 is fixed.

[0031] In a piano, the keyboard 20 is a row of keys that are operating media associated with specific pitches, and is the operating part of a keyboard instrument. In the present invention, however, it is a part of a component of an instrument that resembles a piano, and is configured to move down when pressed with a finger, although it does not produce sound. While the vertical movement of a piano key is 10 mm ± 0.5 mm, in this embodiment, the movement L is 15 mm for practice and finger exercise. While only white keys are illustrated in the present invention, a configuration with black keys may also be used.

[0032] The key end 21 is the side of the key 20 that is engaged with the support shaft 30, opposite to the side that moves down when pressed with a finger.

[0033] The support shaft portion 30 is a member that serves as a shaft for configuring the keyboard 20 so that it descends when pressed with a finger.

[0034] The hinge 40 is a part that supports and enables opening and closing of opening fittings such as swing doors and swing lids, and in the present invention, the hinge 40 is installed so that the keyboard 20 is pressed with a finger and the support shaft part 30 is connected to the back side of the keyboard 20 so that the pressed key 20 returns to its original position.

[0035] The elastic member 50 is made of an elastic material, and in the present invention, it is located on the back of the keyboard 20, above the bottom plate 10, so that when a key 20 is pressed with a finger, the member returns to its original position. It is shaped so that it contacts the back of the key 20 when pressed with a finger, and is located on the bottom plate 10. It may be installed as a single member that spans the length of all the keys 20, or it may be installed for each individual key 20. Coil springs are particularly effective as an example of an installation for each key 20.

[0036] The keyboard groove 51 is a groove that holds the upper side of the elastic member, and is provided so as to hold the coil spring 53 and the like on the underside of the keyboard 20 so that they do not come off when the keyboard 20 is operated (see FIG. 2(d)). However, this groove may be replaced with a protrusion that fits into the inside of the coil spring 53.

[0037] The bottom plate groove 52 is a groove that holds the underside of the elastic member and is provided to prevent the coil spring 53 and the like from coming off when the keyboard 20 is operated (see FIG. 2(d)). However, this groove may be replaced with a protrusion that fits into the inside of the coil spring 53.

[0038] The coil spring 53 is a compression coil spring, a type of coil spring that rebounds under compressive load. It is the most widely used spring component and is used in many machines and devices. Its primary use is to absorb compressive loads, compress them, and utilize the reaction force, mitigating shock and vibration in the compressive direction. The coiled wire itself is primarily subjected to a torsional moment, causing the wire to torsionally deform, causing the spring as a whole to expand and contract. The spring's elastic energy per unit volume during deformation is greater than that of other spring components, resulting in high energy absorption efficiency. Therefore, it also has the advantage of requiring a relatively small installation space. The coil spring 53 used in the piano training device of the present invention compresses when a key is struck by a finger, and elastically deforms when the finger is released, returning the key to its original position. The coil spring 53 may also be replaced with a torsion spring, depending on the hinge configuration used.

[0039] The retaining plate 54 is a plate-like member having a retaining groove for retaining an elastic member, and is provided on the upper surface of the bottom plate 10 and has a thickness that allows the coil spring 53 to be received in the retaining plate 54. If the bottom plate 10 is thick, a groove for receiving the coil spring 53 may be dug directly in the bottom plate 42 without providing the retaining plate 54. The presence of the retaining plate 54 prevents the coil spring 53 from falling off, and also holds the coil spring 53 during assembly and disassembly, which has the advantage of making the assembly and disassembly easier.

[0040] Although not shown in the drawings, elastic material 55 may be any material that utilizes the elastic properties of a single rod-shaped foam such as urethane or hollow rubber, and there are no limitations on the material or shape. Alternatively, a single rod-shaped body may have slits for each key, allowing it to respond individually to the action of the key.

[0041] The amount of movement L indicates the amount of up and down movement when a finger strikes a key, as shown in Figure 3. On a normal piano, this amount is 10 mm plus or minus 0.5 mm, but if you can press the key deeper than this amount, not only will it increase the range of motion of the finger joints, but it will also put a strain on the finger movement, making it practice method 2 that improves finger movement.

[0042] FIG. 3 is an explanatory diagram showing the operation of the piano training device of the present invention when pressed with a finger, showing the state in which the key 20 is pressed with a finger, and the elastic member 50 sinks down around the support shaft portion 30.

[0043] FIG. 4 is an explanatory diagram of another use state of the piano training device of the present invention, showing thumb crossing and octave practice. FIG. 4(a) is an explanatory diagram of use state of practice, showing finger spreading practice to play octaves. FIG. 4(b) and FIG. 4(c) show an example of thumb crossing practice, where FIG. 4(b) shows the middle finger playing the note "E," and FIG. 4(c) shows the movement flow of playing the note "E" by crossing the thumb under the index finger and middle finger to play the note "E." In this way, using the piano training device of the present invention results in piano practice method 2, which allows you to expand the range of finger movement and easily practice the unique finger movements required for piano playing.

[0044] Figure 5 is an explanatory diagram showing the connected state of the piano training equipment 1 of the present invention, where Figure 5(a) shows a plan view from above and Figure 5(b) shows a bottom view from the bottom side, and this connected configuration employs a configuration in which multiple adjacent piano training equipment 1 are integrated together by connecting parts 60.

[0045] The connecting portion 60 is provided when a configuration is adopted in which the piano training apparatus 1 according to the present invention can be connected, and the shape is shown merely as an example, and the shape and structure shown in the drawings are not particularly limited. For example, a female-shaped notch could be provided on the side where the piano training apparatus 1 butts together, and a male-shaped piece 61 that matches the female-shaped notch could be fitted into the notch. In this way, there is no need to provide a protruding portion, and the bottom plate 10 can be made into a sleek shape.

[0046] The piece 61 is a male-shaped piece 61 that matches the shape of a female-shaped notch that is formed in the butted side portions when connecting the training apparatus 1 according to the present invention. [Industrial Applicability]

[0047] The piano training device of the present invention is believed to have high industrial applicability, as it can provide a simple and portable training device to many people who wish to master the piano, a popular musical instrument, and thus can be used to practice at a higher level.
