Description

[0001] SPECIFICATION TECHNICAL FIELD

[0002] The present invention belongs to the technical field of piano auxiliary practice equipment. It is a hand shape molding and improper hand shape correction training device for piano practice. BACKGROUND

[0003] Nowadays, the number of people learning piano is large, and there are millions of new piano students every year. Almost all beginners have the problem of incorrect hand shape, such as folded fingers, collapsed palms, and pressed wrists, etc. Teachers teach hand shape by hand, and the students return to the original state after leaving the teacher. Teachers invest a lot of time and effort in correcting the hand shape of students. Students are distressed, and parents are anxious. If good habits cannot be formed, incorrect hand shape not only affects aesthetics, but also forms a certain degree of obstacle to improving playing skills, and greatly reduces the expressiveness of music.

[0004] At present, there is a corrector for hand shape on the market. This corrector is generally a horizontal bar placed in front of the keyboard and close to the wrist position when playing. The wrist of the piano player is placed on the horizontal bar to prevent the wrist from collapsing. In this way, the wrist cannot collapse, but the fingers are not effectively intervened, and the hand shape is difficult to change substantially, and the piano performance is still affected. SUMMARY

[0005] The present invention is a hand shape molding and improper hand shape correction auxiliary training device that is tailored for different types of students and fundamentally solves the problem of hand shape. It can also solve the problem of wrist pressure while solving the problem of hand shape.

[0006] The present invention adopts the following two technical solutions: 1. Use the standard hand shape of the student as the inner mold, and make a hand shape molding device based on this inner mold as a template. This hand shape molding device is placed on the piano keyboard, and the student places his hand on the molding device (hand shape mold) to practice playing with five fingers. Naturally, the hand shape played on the molding device is the standard hand shape, and after a period of practice, the student's hand shape will be stable and maintain a standard state. This solution is particularly suitable for five-finger practice and fixed position practice for beginners. 2. Place a strip frame with a total length equivalent to the length of the piano keyboard, two rows in front and back, low in front and high in back (to adapt to the correct angle of the standing thumb), connected bottom plate, U-shaped section with a spike, forming two barriers, so that the player's hand cannot cross, the thumb cannot be placed flat, and cannot be stretched out of the keyboard. The thumb must stand at a certain angle on the piano keys. After a period of practice, the problems of collapsed palms, pressed wrists, folded fingers, and other problems will be solved.

DETAILED DESCRIPTION

[0017] The embodiments of the present technology will be described in detail below with reference to the accompanying drawings.

[0018] A piano child hand shape molding and improper hand shape correction training device, comprising a molding device 1, a strip frame type cone double barrier correct finger training device 2, a supporting seat 3 and a clamping device 4. The supporting seat 3 and the upper part of the clamping device 4 are integrally connected, and are fixed on the piano lock door stop 27. The molding device 1 of one of the schemes is guided into the positioning by the positioning slide 16 of the positioning workbench 14 along the guide rail 8 of the supporting seat 3, and the molding die 15 of the molding device 1 is placed on the piano keyboard 26. The connecting plug plate 22 at the end of the strip frame type cone double barrier correct finger training device 2 of the second scheme is inserted into the seat groove 9 of the supporting seat 3, and is horizontally placed on the piano lock door stop 27. The two schemes can be selected according to the specific situation of the child.

[0019] The upper part of the supporting seat 3 and the clamping device 4 is integrally connected, and the supporting seat is located above the piano lock door stop 27, and the top of the supporting seat is provided with guide rails 8, and two vertical seat grooves 9 are arranged on the two sides of the supporting seat.

[0020] The long nut (10) fixed on the upper part 5 of the clamping device is connected with the lower part 6 of the clamping device by a bolt 11 with a handle, and the handle 7 is rotated to adjust the height of the bolt 11 according to the size of different types of pianos, and the clamping device is fixed on the piano lock door stop 27.

[0021] The main material of the supporting seat 3 and the clamping device 4 is ABS, which can ensure the affinity with the piano and the strength.

[0022] The inner side of the corner of the upper part 5 of the clamping device and the lower part 6 of the clamping device is arc-shaped, which greatly improves the strength and rigidity.

[0023] The upper and lower parts of the clamping device 4 in contact with the piano are respectively attached with silica gel sheets 12 and 13, which not only enhances the adhesion of the contact surface, but also effectively protects the piano, so that the paint surface is not damaged.

[0024] The main function part of the molding device 1 is the molding die 15, which is shaped like the standard hand shape of the child when playing the piano, that is, the shape of the palm of the half clenched fist, which is irregular hemispherical.

[0025] The positioning workbench 14 is provided with three layers of positioning slides 16 on the two sides of the inside of the positioning workbench 14, and the height can be adjusted as needed.

[0026] A row of cone spikes 17 is arranged at the tail of the molding device 1 to prevent the wrist from pressing down and excessively relying on the molding device when playing the piano.

[0027] The total length of the strip frame type cone double barrier correct finger training device 2 is more than four octaves, which is a long strip frame with U-shaped section, with two rows of front and back, low front and high back, and connected bottom plates.

[0028] The strip frame type double barrier positive finger training device 2 is composed of several sections connected with each other by inserting the two end inserting plates 22 into the inserting ports 24, 25 of the connecting card seats 23 and clamping, and the two ends after connection are also inserted into the falling seat grooves 9 of the supporting seats 3 and stably placed on the piano lock door stop 27.

[0029] The cross section of the strip frame type double barrier positive finger training device 2 is adapted to the correct angle of the thumb played by a child playing the piano, so that the played thumb is kept at a certain angle.

[0030] The strip frame type double barrier positive finger training device 2 is provided with the double barriers of the cone stings 20, 21 on the upper surface, so that the hand cannot approach and cannot pass the barriers to the outside of the keyboard.

[0031] The tail cone sting 17 of the shaper 1 and the upper cone stings 20, 21 of the strip frame type double barrier positive finger training device 2 are not the cone stings in the shape of an equilateral triangle, but the cone stings with the arc at the top end, so that the hand only feels a little pain when touching it, only plays a warning role and does not cause harm.

[0032] The core of the application is the hand shape molding and the double barrier positive finger, the above description describes some specific implementation methods of the application, which is helpful to understand the spirit of the application, but this is not the only scheme, other combinations can be used, and a certain part can be changed, as long as it does not deviate from the concept and spirit of the application, it is within the protection scope of the appended claims of the application.
