Description

Technical Field

[0001] The present invention relates to a finger training device and a practice method for a piano. More specifically, it is a practice device for enabling the user to freely control the movement of the fingers for playing the piano and the strength of striking the keyboard, and relates to the technology of a portable and convenient finger training device and practice method for a piano that can be practiced anywhere, regardless of whether it produces sound, and is similar in shape to the keyboard.

Background Art

[0002] The piano can be said to be one of the representative musical instruments for playing music. It is particularly widely popular and has a strong popularity among hobbies such as attending piano classes from a young age. However, the strength of the fingers when playing the piano is unexpectedly weak for those who are not used to it, and it is not possible without repeated practice not only for young children but also for adults. In addition, young children have small hands and it is difficult for them to reach an octave. They also need to practice spreading their hands wide, so there is a need for an instrument that can be easily practiced anywhere.

[0003] Moreover, especially to play the sound of the piano beautifully, the best way to move the fingers is determined by the flow of the sound. Practicing the correct finger movement is also necessary to play the piano well. In addition, it is also important to freely control the strength of the sound. In music, techniques such as playing louder and louder or softer and softer, such as piano, pianissimo, mezzo forte, forte, crescendo, diminuendo, etc., are required to freely control the strength of the sound. It is undoubtedly difficult for young children to acquire these techniques, and it can be said that repeated practice is necessary to overcome them.

[0004] However, although it is repetitive practice that is necessary, depending on the home environment and housing conditions, there are various conditions such as location and time, and there are cases where practice cannot be done in the early morning or late at night considering disturbing the neighbors. Furthermore, in families with cohabiting family members, especially in families with examinees, the practice time is limited, such as interfering with the study of siblings. Therefore, there is a demand for the development of an instrument that allows easy practice of the piano without making a sound. Also, development has been carried out on these practice instruments in the past. However, these practice instruments were large-scale, inconvenient for storage and carrying, and could not be said to be easy to practice with. Therefore, the development of a compact and smartly storable and easily portable piano practice instrument is desired.

[0005] Therefore, in view of such problems, various technical proposals have been made in the past. The name of the invention is "Auxiliary tool for practicing keyboard instruments and set of auxiliary tools for practice", and the problem to be solved is "To provide an auxiliary tool for practicing keyboard instruments and a set of auxiliary tools for practicing keyboard instruments that can be confirmed not only by the instructor but also by the student himself / herself in the correct position on the keyboard and can play beautiful sounds", and the specific solution means is that "The auxiliary tool 2 for practicing keyboard instruments is a plate-shaped body made of resin with a mirror finish in a substantially rectangular shape in plan view, with the corners being semi-circular, a thickness (t) of 1.0 mm, a height (h) of 9.3 mm, and a width (w) of 17.3 mm, and is detachably attached to the inside of the keyboard cover 1, and the seal 4 is detachably attached to each keyboard 3 as a mark so as to be in an appropriate position according to the length of the student's finger." However, although such technology has a common point in that it is a practice aid that facilitates guidance such as the correct finger placement, the solution means is that the student himself / herself and the instructor consider the length of the finger and other factors and stick a seal on the piano keyboard and use it as a mark for practice. However, in the present invention, it is possible to practice the correct movement of the fingers and the strength of the fingers hitting the keyboard even without a piano by using an instrument similar to a part of the keyboard, and the solution means is different.

[0006] Also, the name of the invention is set as "Piano Practice Tool", and the problem to be solved is set as "To provide a piano practice tool that can perform training to keep the base of the thumb soft and move the first and second joints of the thumb in a bent shape in order to smooth the thumb passage necessary for playing the piano." The specific solution means is "A piano practice tool A having a knob 2 that can be rotated while pinching with the thumb and another finger opposing it, and the diameter of the knob 2 is set to a width such that the thumb can be inserted between the fingertips of the other finger with the fingertip of the thumb bent inward. The piano practice tool A includes a cylindrical body 1, and a string 3 and a weight 4 that are wound up by rotating the cylindrical body 1 with the thumb and the other finger are attached to the central part of the cylindrical body 1. Also, a knock mechanism is incorporated in the cylindrical body 1, and the tip button of the knock mechanism protrudes from the central axis of the knob 1 part, and is configured to emit a sound when the button is pressed." However, such a technique is common with the present invention in that training is possible as long as there is an instrument even in a place where there is no piano, but it is a practice instrument specialized for the thumb passage necessary for piano performance, and it cannot be expected to move and train all fingers like the present invention.

[0007] Also, the name of the invention is set as "Piano Practice Equipment", and the specific solution means is "A piano practice equipment in which a number of keyboards are pivotally supported at the rear end between the two rising sides of the frame body and are resiliently interposed between the bottom of the frame body and are held in a horizontal state so as to operate elastically when finger pressure is applied to the front end." Such a technique has a crossbar arranged above the keyboard to restrict the upward movement of the keyboard. Therefore, even if there are few risers supporting the crossbar, they are arranged left and right, protrude with respect to the keyboard, lack in smartness, and also become an obstacle when connecting. On the other hand, the present invention is different in that it is possible to make it have no protruding parts in the up and down, left and right, and front and back directions of the keyboard. As an effect of such a difference, since there are no protruding parts during carrying, it becomes easy to store in a bag or the like like handling books and notes.

[0008] Also, the name of the invention is set as "Performance Practice Device, Keyboard Instrument, and Finger Dexterity Practice Device", and the object to be solved is set as "To provide a performance practice device, a keyboard instrument, and a finger dexterity practice device that enable even beginners who have just started practicing the performance of a keyboard instrument to easily perform or practice performing." The specific solution means is "The performance practice device according to the present invention includes storage means for storing music data including a plurality of keys corresponding to any one of the fingers of each hand and finger dexterity data for specifying finger dexterity, control means for reading out and outputting the music data stored by the storage means, detection means for detecting the key that has been pressed among the plurality of keys, and when the key corresponding to the finger specified by the finger dexterity data in the music data output by the control means and the key detected by the detection means satisfy a predetermined condition, tone signal generation means for generating and outputting a tone signal according to the performance data in the music data output by the control means." Such technology is limited to practicing only the existing keyboard because there are frames on both sides of the keyboard. However, the present invention has the feature that a plurality of practice tools can be connected without the presence of a frame, and the effects are different from those of the present invention.

Best Mode for Carrying Out the Invention

[0024] The piano training instrument of the present invention has a bottom plate 10, a plurality of keyboards 20, a support shaft portion 30, and an elastic member 50. The support shaft portion 30 is clamped between the bottom plate end portion 11 of the bottom plate 10 and the keyboard end portion 21 of the keyboard 20. The support shaft portion 30 supports the keyboard 20 rotatably via a hinge 40 provided for each keyboard 20, and abuts against the keyboard end portion 21 to regulate the movement. The elastic member 50 is provided between predetermined positions of the bottom plate 10 and the keyboard 20. The elastic member 50 is a coil spring 53 and is held by a holding plate 54 provided on the upper surface of the bottom plate 10, which is the most characteristic feature. Hereinafter, it will be described with reference to the drawings. However, it is not limited to the shapes and configurations shown in the drawings, and can be changed within the scope where the effects of the creative technical idea of the present invention can be obtained.

[0025] FIG. 1 is a basic configuration explanatory diagram for explaining the basic configuration of the piano training instrument according to the present invention, showing the relationship among the bottom plate 10, the keyboard 20, the support shaft portion 30, and the elastic member 50.

[0026] The piano training instrument 1 has a bottom plate 10, a plurality of keyboards 20, a support shaft portion 30, and an elastic member 50. The support shaft portion 30 is clamped between the bottom plate end portion 11 of the bottom plate 10 and the keyboard end portion 21 of the keyboard 20. The support shaft portion 30 supports the keyboard 20 rotatably via a hinge 40 and abuts against the end portion of the keyboard 20 to regulate the movement. The elastic member 50 is provided between predetermined positions of the bottom plate 10 and the keyboard 20, which is the basic configuration.

[0027] Figure 2 is a front view, side view, and plan view for explaining the basic configuration of the piano training 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) shows a cross-sectional view taken along line A-A from the side. As shown in Fig. 2(a), when the piano training instrument 1 according to the present invention has no protruding portion from the keyboard 20 in a top view and is connected, it can form an arrangement configuration similar to that of a formal keyboard arrangement. Therefore, when connected by protruding one-half of the gap amount between the keyboards to the side, it can have the same arrangement configuration as the white keys of a piano. Figs. 2(b) and 2(c) show the configuration of the piano training instrument 1 according to the present invention. In the embodiment shown in Fig. 2(d), an example using a coil spring 53 as an elastic member is shown, and a holding plate 54 may be provided to provide keyboard side grooves 51 and bottom plate side grooves 52 for holding the coil spring 53 vertically so that the coil spring 53 does not come off due to the operation of hitting the keyboard. Each of the following constituent members will be described in detail below.

[0028] The piano practice method 2 is a method for efficiently practicing using the piano training instrument 1.

[0029] The bottom plate 10 is a pedestal that serves as a base in the piano training instrument 1.

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

[0031] The keyboard 20 is an arrangement of keys, which are operating media associated with specific pitches in a piano and are the operating part of a keyboard instrument. In the present invention, it is a part of a member of an instrument modeled after a piano. Although it does not produce sound, it is a part modeled after the keyboard of a piano configured to descend when pressed with a finger. In the case of a piano keyboard, the vertical movement amount is plus or minus 0.5 mm from 10 mm, whereas in the embodiment for practice and finger movement, the movement amount L is 15 mm. Although only white keys are exemplified in the present invention, a configuration with black keys may also be used.

[0032] The keyboard end 21 is the side locked to the support shaft portion 30 on the side opposite to the side that descends when pressed with a finger on the keyboard 20.

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

[0034] The hinge 40 is a component that enables the support and opening / closing of opening fixtures such as opening doors and lids. In the present invention, it is installed to connect the support shaft portion 30 to the back side of the keyboard 20 so that when the keyboard 20 is pressed with a finger, the pressed keyboard 20 returns to its original position.

[0035] The elastic member 50 is made of a material with elasticity. In the present invention, when the keyboard 20 pressed with a finger uses the member, it is located above the bottom plate 10 on the back side of the keyboard 20 so as to return to its original position. The shape is located on the bottom plate 10 so as to hit the back side of the keyboard 20 when pressed with a finger, and it is installed as one member having the length of all the keyboards 20 arranged side by side, or it may be installed for each individual keyboard 20. In particular, as an example of installation for each keyboard 20, it can be said that a coil spring or the like is also effective.

[0036] The keyboard side groove 51 is a groove for holding the upper side of the elastic member, and is provided to be held on the lower side of the keyboard 20 so that a coil spring 53 or the like does not come off when the keyboard 20 is operated (see Fig. 2(d)). However, such a groove may be replaced with a protrusion that enters the inside of the coil spring 53.

[0037] The bottom plate side groove 52 is a groove for holding the lower side of the elastic member, and is provided for holding so that a coil spring 53 or the like does not come off when the keyboard 20 is operated (see Fig. 2(d)). However, such a groove may be replaced with a protrusion that enters the inside of the coil spring 53.

[0038] The coil spring 53 is a compression coil spring, which is a type of coil spring that repels under a compressive load. It is the most widely used among spring components and is used in many machines and appliances. It is mainly used for applications such as receiving a load in the compression direction, compressing it, and utilizing the reaction force to relieve the impact and vibration in the compression direction. A torsional moment is mainly applied to the wire itself formed in a coil shape, and when the wire undergoes torsional deformation, the spring as a whole expands and contracts. The elastic energy per unit volume when the spring deforms is large compared to other spring components, and the energy absorption efficiency is high. Therefore, it also has the advantage that the space required for installation is relatively small. The coil spring 53 used in the piano training instrument according to the present invention is compressed by hitting the keyboard by the operation transmitted from the finger, and functions to return the keyboard to its original state by elastic deformation when the finger is released. Note that the coil spring 53 may be replaced with a torsion spring and used appropriately depending on the configuration of the hinge used.

[0039] The holding plate 54 is a plate-shaped member having a holding groove for holding an elastic member, and has a thickness for receiving the coil spring 53 on the upper surface of the bottom plate 10. When the bottom plate 10 has a thickness, a groove for receiving the coil spring 53 may be directly dug in the bottom plate 42 without providing the holding plate 54. The presence of such a holding plate 54 can prevent the coil spring 53 from falling off, and since the coil spring 53 is held during assembly and disassembly, there is an advantage that such assembly and disassembly are easy.

[0040] Although not shown in the drawings, the elastic material 55 may be, for example, any material that can utilize elastic properties such as urethane, which is a single rod-shaped foam, or hollow rubber, and may be any material and shape that can be utilized without being limited thereto. Also, a slit for each keyboard may be provided in the integrated rod-shaped body so that it can correspond to the operation of each keyboard individually.

[0041] The movement amount L indicates the up-and-down movement amount when hitting the keyboard with a finger, as shown in FIG. 3. In the case of a normal piano, this amount is 10 mm plus or minus 0.5 mm. However, when the keyboard can be pushed down deeper than this amount, it not only expands the movable area of the finger joints but also applies a load to the movement of the fingers, which becomes Practice Method 2 for improving finger movement.

[0042] FIG. 3 is an operation explanatory diagram showing the state of the piano training instrument according to the present invention being pressed by a finger. It shows the keyboard 20 being pressed by a finger and descending about the support shaft portion 30, with the elastic member 50 being depressed.

[0043] FIG. 4 is another usage state explanatory diagram of the piano training instrument according to the present invention for practicing thumb-through and octave. FIG. 4(a) is a usage state explanatory diagram for practicing spreading the fingers to hold an octave. FIGS. 4(b) and 4(c) show the flow of an example of practicing thumb-through. FIG. 4(b) shows the state of playing the note "mi" with the middle finger, and FIG. 4(c) shows the flow of the operation of playing the note "fa" by passing the thumb under the index finger and the middle finger from the note "mi". By using the piano training instrument according to the present invention in this way, it becomes Practice Method 2 for the piano, which can expand the movable area of the fingers and easily practice the unique finger movement required for piano performance.

[0044] FIG. 5 is a connection state explanatory diagram showing the state of connecting the piano training instrument 1 according to the present invention. FIG. 5(a) shows a plan view when viewed from above, and FIG. 5(b) shows a bottom view when viewed from the bottom side. Such a connection configuration adopts a configuration in which a plurality of adjacent piano training instruments 1 are integrated by a connecting portion 60.

[0045] The connecting part 60 is provided when adopting a configuration capable of connecting the piano training instrument 1 according to the present invention. Regarding the shape, it is merely shown as an example, and the shape and structure shown in the drawings are not particularly limited. For example, a female-shaped notch may be provided on the side surface where the piano training instrument 1 abuts, and a male-shaped piece 61 that matches such a shape may be fitted, such as a fitting type. In this way, there is no need to provide a protruding part, and the bottom plate 10 can have a smart shape.

[0046] The piece 61 is a male-shaped piece 61 that matches the shape of a female-shaped notch formed on the abutting side when connecting the training instrument 1 according to the present invention.

Industrial Applicability

[0047] According to the piano training instrument of the present invention, since there are many people who want to acquire higher-level techniques for the popular musical instrument piano, and it is possible to provide a practice instrument that is easy to carry around, it is considered to have high industrial applicability.
