Description

Technical Field

[0001] The utility model relates to the technical field of music auxiliary appliances, and particularly relates to a teaching piano page turner. Background Art

[0002] In the art of music performance, pianists and other instrumentalists often face a challenging task: managing the page turning of sheet music while focusing on playing. This process requires musicians to free up their hands to turn the sheet music while maintaining musical expressiveness and skills, which not only distracts attention but also may affect the fluency and precision of the performance. Traditional page turning methods rely on manual operation, which not only increases the burden on performers but also has low efficiency and is difficult to adapt to fast-paced or high-difficulty pieces.

[0003] To solve this problem, the prior art has attempted to introduce automated page turning devices that use motors to drive robotic arms to automatically flip the sheet music pages, aiming to free the hands of performers and improve the professionalism and aesthetics of performances. However, although these devices simplify the page turning process to some extent, they still have significant limitations. In particular, the page turning control is not accurate enough, often resulting in turning too many pages at once, which not only disrupts the coherence of the performance but also imposes an additional cognitive load on musicians, limiting their application potential in professional settings. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a teaching piano page turner to solve the existing problems.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A teaching piano page turner, comprising:

[0006] A support plate, in the middle of which a receiving area for placing sheet music is formed, and an installation edge protrudes from one side edge thereof. The end face of the support plate forms a page turning side and a fixed side that are symmetrically distributed with the receiving area as the center;

[0007] A page turning mechanism, including a page turning motor provided on the installation edge, a page turning connecting rod fixed to the output shaft of the page turning motor, a rotating motor provided at the other end of the page turning connecting rod, and a rotating rod coaxially fixed to the output shaft of the rotating motor. The page turning connecting rod is perpendicularly distributed with respect to the output shaft of the page turning motor, and the output shaft of the rotating motor and the rotating rod are perpendicularly distributed with respect to the page turning connecting rod. A plurality of deformable flexible friction members are provided along the axial direction of the rotating rod. The page turning motor drives the rotating motor and the rotating rod to swing between the page turning side and the fixed side through the page turning connecting rod;

[0008] A fixing mechanism, including a fixing plate erected on the edge of the fixed side and a fixing cylinder obliquely provided on the fixing plate. The output shaft of the fixing cylinder obliquely faces the end face of the support plate.

[0009] By adopting the above technical solution, the rotation of the motor controls the swing of the rotating rod. The flexible friction member on the rotating rod presses down on the music score page with a certain pressure and friction, turning over the music score pages one by one. When it rotates one week, a single music score page is turned up to the upper end of the rotating shaft. Then, by the rotation of the page-turning motor, the single music score page can be turned from the page-turning side to the fixed side. Finally, through the rising and yielding of the fixed cylinder and then pressing down again, the music score page is fixed on the fixed side, realizing automatic and precise page-turning of the music score.

[0010] The present utility model is further configured such that the flexible friction member is locked and fixed to the rotating shaft through a fixing ring sleeve, and a plurality of flexible friction members are uniformly distributed along the rotating shaft.

[0011] By adopting the above technical solution, a plurality of flexible friction members are uniformly distributed along the rotating shaft, which can provide a uniform contact surface during page-turning, avoiding damage to the music score or uneven page-turning caused by excessive local pressure. This design ensures that each page-turning can be executed with the same pressure and speed, improving the accuracy and reliability of page-turning.

[0012] The present utility model is further configured such that the flexible friction member is a rubber thin sheet, and the flexible friction member is in the shape of a blade.

[0013] By adopting the above technical solution, due to the soft and elastic characteristics of the rubber thin sheet, it can gently contact the surface of the music score, reducing the risk of wear and tear on the paper during page-turning, especially suitable for precious or fragile music scores. In addition, the high friction coefficient of the rubber material helps to ensure the reliability and accuracy of the page-turning action, and can effectively grip and not slip even when facing a smooth music score cover. Designing the flexible friction member in the shape of a blade is to maximize the contact area within a limited space, while reducing the single-point pressure to prevent the music score from being pressed and deformed or damaged.

[0014] The present utility model is further configured such that the flexible friction members are distributed obliquely along the rotating shaft.

[0015] By adopting the above technical solution, the obliquely distributed flexible friction members will form an increasingly larger contact angle during page-turning. In this way, a smaller contact force can be provided at the initial stage of page-turning, and the contact force gradually increases as the page-turning action progresses, thus realizing a smoother and more controllable page-turning experience.

[0016] The present utility model is further configured such that a plurality of strip-shaped friction strips are integrally protruded on the surface of the flexible friction member.

[0017] By adopting the above technical solution, the strip-shaped friction strips can increase the effective friction area on the contact surface. Even when the contact area is limited, sufficient frictional force can be ensured to turn the music score, especially when it is necessary to turn the pages of a heavy or thick music score; in addition, the design of the strip-shaped friction strips helps to disperse the pressure and avoid leaving obvious indentations or damages on the music score.

[0018] The present utility model is further configured to further include a pressing member. The pressing member is disposed on the side of the page-turning side away from the page-turning motor, and the pressing member includes a support and an elastic pressing piece locked and fixed on the support. The movable end of the elastic pressing piece extends to a position close to the end face of the support plate.

[0019] By adopting the above technical solution, the pressing member is located on the side of the page-turning side away from the page-turning motor. Its main function is to apply appropriate pressure to the unturned part of the music score during the page-turning process to prevent unnecessary movement or warping of the music score during page-turning, ensuring the precise execution of the page-turning action. During the page-turning process, the elastic pressing piece can prevent the unturned part from being driven along with the page-turning action, avoiding the problem of multiple pages being turned simultaneously, thereby ensuring that only one page is turned each time and improving the accuracy and coherence of page-turning.

[0020] The present utility model is further configured to further include that the elastic pressing piece includes a horizontal section fixed to the support, a connecting section extending obliquely downward along the edge of the horizontal section, and a pressing section extending horizontally along the bottom of the connecting section. There is a gap between the pressing section and the end face of the support plate.

[0021] By adopting the above technical solution, the elastic pressing piece includes a horizontal section, a connecting section, and a pressing section, and there is a certain gap between the pressing section and the end face of the support plate, which can effectively press the music score while avoiding direct contact with the support plate and reducing potential damage to the music score.

[0022] The present utility model is further configured to further include a clamping mechanism. A clamping groove parallel to the rotating rod and used for accommodating the spine of the music score is provided in the middle of the accommodating area. Installation grooves are provided on both sides of the clamping groove. The clamping mechanism includes a clamping plate slidably disposed along the installation groove in a direction approaching or departing from the clamping groove and an elastic member for elastically ejecting the clamping plate so that it has a tendency to move towards the clamping groove.

[0023] By adopting the above technical solution, the clamping groove in the middle of the accommodating area is specifically used for accommodating the spine of the music score, ensuring that the music score can be stably positioned when placed, avoiding possible offset or sliding of the music score during the page-turning process, thereby improving the accuracy and stability of page-turning; the installation grooves on both sides of the clamping groove provide tracks for the sliding of the clamping plate. The clamping plate can slide along the installation groove in a direction approaching or departing from the clamping groove, and the user can easily adjust the position of the clamping plate according to the thickness of the music score to ensure that the music score is properly clamped without being subjected to excessive pressure.

[0024] The present utility model is further configured such that limiting edges are formed on both sides of the clamping plate along its length direction, limiting grooves adapted to the limiting edges are formed on both sides of the installation groove, and the elastic member is a return spring and is disposed on a side of the installation groove away from the clamping groove.

[0025] By adopting the above technical solution, the limiting edges of the clamping plate cooperate with the limiting grooves of the installation groove to form a stable guiding system, ensuring the linearity and stability of the clamping plate during sliding. It can effectively prevent the lateral movement or shaking of the clamping plate during operation, guarantee the precise fixation of the spine of the music score, and thus improve the accuracy and reliability of page turning.

[0026] The present utility model is further configured such that a handle groove is provided in the middle of the clamping plate.

[0027] By adopting the above technical solution, the handle groove provided in the middle of the clamping plate provides a convenient operation interface for users, making it simpler and more intuitive to adjust the position of the clamping plate.

[0028] In summary, the present utility model mainly has the following beneficial effects:

[0029] The present utility model can precisely control the number of pages turned, ensuring that only one page is turned each time, and at the same time has high responsiveness and reliability to meet the strict requirements of professional performers for accuracy and smoothness.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

On the end face of the support plate 10, a page-turning side 13 and a fixed side 14 symmetrically distributed with the accommodation area 11 as the center are formed;

[0039] A page-turning mechanism, including a page-turning motor 20 provided on the installation edge 12, a page-turning connecting rod 30 fixed to the output shaft of the page-turning motor 20, a rotating motor 40 provided at the other end of the page-turning connecting rod 30, and a rotating rod 50 coaxially fixed to the output shaft of the rotating motor 40. The page-turning connecting rod 30 is perpendicularly distributed to the output shaft of the page-turning motor 20, the output shaft of the rotating motor 40 and the rotating rod 50 are perpendicularly distributed to the page-turning connecting rod 30. Along the axial direction of the rotating rod 50, a plurality of deformable flexible friction members 60 are provided. The page-turning motor 20 drives the rotating motor 40 and the rotating rod 50 to swing between the page-turning side 13 and the fixed side 14 through the page-turning connecting rod 30;

[0040] The fixing mechanism 70 includes a fixing plate 71 erected on the edge of the fixed side 14 and a fixing cylinder 72 inclined on the fixing plate 71.

In this embodiment, a spherical flexible pressing block 73, such as a rubber block or a silicone block, is provided at the end of the output shaft of the fixing cylinder 72. Thus, by controlling the swing of the rotating rod 50 through the rotating motor 40, the flexible friction member 60 on the rotating rod 50 turns up the music score page by page by pressing with a certain pressure and friction on the music score. After one rotation, a single music score page is turned up to the upper end of the rotating shaft. Then, by the rotation of the page-turning motor 20, the single music score page can be turned from the page-turning side 13 to the fixed side 14.
