Description

Technical Field

[0001] This utility model relates to the field of musical instrument playing aids, specifically a foot-operated sheet music turning device. Background Technology

[0002] Currently, conventional music stands only provide support for sheet music, requiring manual page turning during instrument playing. This disrupts the flow of the performance and causes inconvenience for the player. Furthermore, accidentally turning several pages at once can lead to serious consequences, such as playing the wrong piece of music. Therefore, a foot-operated music stand with page turning capabilities has emerged on the market.

[0003] However, most of these music stands are mechanically driven, requiring installation space for these transmission structures. Therefore, they cannot be used on finished pianos or similar structures. Furthermore, since pianos have built-in music stands, pianists still need to manually turn the pages, which can easily disrupt the playing rhythm and affect the flow of the music. Utility Model Content

[0004] The purpose of this invention is to provide a foot-operated sheet music turning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A foot-operated sheet music turning device includes: A music stand includes a back panel, a second motor is fixedly installed on the upper rear surface of the back panel, a cantilever is fixedly installed at the output end of the second motor, a third motor is embedded at the bottom front end of the cantilever, and a rubbing wheel is fixedly installed at the output end of the third motor. The fixing clamp includes a first clamp plate and a second clamp plate, wherein the first clamp plate is fixedly installed on the upper edge of the rear side of the back plate; A control foot pedal includes a base plate, the upper front edge of which is hinged to a pedal via a coil spring shaft.

[0006] Furthermore, a bracket is fixedly installed on the bottom side of the back plate, a limiting clamp is slidably installed on the inner bottom of the bracket, and an electromagnetic push rod is fixedly inserted in the middle of the front side of the bracket, with the output end of the electromagnetic push rod being fixedly connected to the limiting clamp.

[0007] Furthermore, a motor is embedded in the upper surface of the bracket, and a page-turning lever is fixedly installed at the output end of the motor.

[0008] Furthermore, an electrical control box is fixedly installed in the middle of the upper rear edge of the back panel, and battery slots are fixedly installed at both ends of the upper rear edge of the back panel, with replaceable batteries inserted inside the battery slots.

[0009] Furthermore, the first clamping plate and the second clamping plate are each fixedly installed with a fulcrum support frame in the middle of their adjacent surfaces. The two sets of fulcrum support frames are hinged to each other by a connecting shaft. The two ends of the connecting shaft are fitted with snap rings. A force plate is fixedly installed on the upper edge of the second clamping plate, and a threaded top column is screwed into the middle of the force plate.

[0010] Furthermore, the base plate has anti-slip pads fixedly attached to its front and rear edges, a second electrical control box is fixedly installed on the upper surface of the base plate, a charging interface is embedded in the rear surface of the second electrical control box, a signal enhancement antenna is embedded in one edge of the rear surface of the second electrical control box, and contact pieces are embedded in the upper surface of the second electrical control box and the bottom side of the pedal.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The backplate is attached to the front of the original music stand by clamping it with clamps No. 1 and No. 2. The control foot pedal is placed on the side of the tuning pedal at the bottom of the piano. Stepping on the pedal is used as a trigger switch to start motor No. 2 to rotate the cantilever, so that the scribing wheel is in contact with the sheet music. Then motor No. 3 is started to drive the scribing wheel to rotate, scribing the sheet music and turning it over. It is used as an additional auxiliary device in the original structure of the piano. The foot pedal action replaces the player's manual action of turning the pages of the sheet music, ensuring that the player's hand action is uninterrupted and improving the smoothness of the music.

[0012] Before and after page turning, an electromagnetic push rod pushes a limiting clamp to hold the bottom of the sheet music and limit its unfolding. When turning a page, the limiting clamp retracts to open the restriction. First, motor number two is started to adjust the position of the rubbing roller, and then motor number three is started to rotate the rubbing roller to rub the single sheet music into an arch. At this time, motor number one is started to rotate the page turning lever to turn the arched page to the other side. The multi-stage turning structure works in concert to avoid the rubbing roller directly contacting the next sheet music before turning the page, thus turning the next sheet music up at the same time and ensuring that only one sheet music is turned up at a time.

[0013] Two sets of retaining rings provide clamping force to the lower edges of clamping plates one and two. This clamping force is used to temporarily clamp the entire device onto the original sheet music holder. After adjusting the clamping position, the threaded top pin is rotated so that one end of the threaded top pin abuts against the inner surface of clamping plate one. Using the connecting shaft as a fulcrum, it is continuously rotated to replace the elastic clamping force provided by the retaining rings with the rigid clamping force of the threaded top pin. This facilitates installation while ensuring stability during installation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 In this embodiment of the utility model, a foot-operated sheet music turning device includes a music stand 1, a fixing clip 2, and a control foot pedal 3. The music stand 1 includes a back plate 101, a second motor 110 is fixedly installed on the upper rear surface of the back plate 101, a cantilever 111 is fixedly installed at the output end of the second motor 110, a third motor 112 is embedded at the bottom front end of the cantilever 111, and a rubbing wheel 113 is fixedly installed at the output end of the third motor 112. The fixing clip 2 includes a first clamping plate 201 and a second clamping plate 202, the first clamping plate 201 is fixedly installed on the upper rear edge of the back plate 101. The control foot pedal 3 includes a base plate 301, and a pedal 307 is hinged to the upper front edge of the base plate 301 through a coil spring shaft 303.

[0018] Specifically, the first clamp 201 and the second clamp 202 are used to hold the piano on the edge of the original music stand. The back plate 101 is installed on the front side of the original music stand. The control foot pedal 3 is placed on the side of the tuning pedal at the bottom of the piano. By stepping on the pedal 307 as a trigger switch, the second motor 110 is started to rotate the cantilever 111, so that the scribing wheel 113 is in contact with the music sheet. Then the third motor 112 is started to drive the scribing wheel 113 to rotate, scribing the music sheet and turning it over. It is used as an additional auxiliary device in the original structure of the piano. The foot pedal action replaces the player's manual action of turning the pages of the music sheet, ensuring that the player's hand action rhythm is uninterrupted and improving the smoothness of the music. Example 1

[0019] like Figure 1-2 As shown in Figures 4-6, in this embodiment, a bracket 102 is fixedly installed on the bottom side of the back plate 101. A limiting clamp 103 is slidably installed on the inner bottom of the bracket 102. An electromagnetic push rod 104 is fixedly inserted in the middle of the front side of the bracket 102. The output end of the electromagnetic push rod 104 is fixedly connected to the limiting clamp 103. A first motor 105 is embedded on the upper surface of the bracket 102. A page-turning lever 106 is fixedly installed on the output end of the first motor 105. A first electrical control box 107 is fixedly installed in the middle of the upper rear edge of the back plate 101. Battery slots 108 are fixedly installed at both ends of the upper rear edge of the back plate 101. A replaceable battery 109 is inserted inside the battery slots 108. A PLC controller and a wireless signal receiving module are built into the first electrical control box 107.

[0020] In this embodiment, power is supplied by a replaceable battery 109 installed in the battery slot 108. Before and after page turning, the electromagnetic push rod 104 pushes the limiting clamp 103 to hold the bottom of the sheet music and limit the unfolded sheet music. When turning the page, after the limiting clamp 103 is retracted to open the restriction, the second motor 110 is started to adjust the position of the scrubbing wheel 113, and then the third motor 112 is started to rotate the scrubbing wheel 113 to scrubbing the single sheet music until it is arched. At this time, the first motor 105 is started to rotate the page turning lever 106 to turn the arched page to the other side. The multi-stage turning structure works in concert to avoid the scrubbing wheel 113 directly contacting the next sheet music before turning the page, and to turn the next sheet music up together, ensuring that only one sheet music is turned up at a time.

[0021] like Figure 7 As shown, in this embodiment, anti-slip pads 302 are fixedly attached to the front and rear edges of the bottom of the base plate 301. A second electrical control box 304 is fixedly installed on the upper surface of the base plate 301. A charging interface 305 is embedded on the rear surface of the second electrical control box 304. A signal enhancement antenna 306 is embedded on one edge of the rear surface of the second electrical control box 304. Contact pieces 308 are embedded on the upper surface of the second electrical control box 304 and the bottom side of the pedal 307.

[0022] In practice, stepping on pedal 307 causes the two sets of contact plates 308 to come into contact with each other, generating an electrical signal. This signal is then transmitted to the first control box 107 via the built-in wireless transmission module of the second control box 304, triggering the page-turning program. Example 2

[0023] Based on Embodiment 1, in order to supplement the specific method of using the fixing clip 2 to securely clamp the entire device to the original music stand of the piano, which was not mentioned in Embodiment 1.

[0024] like Figure 3 As shown, in this embodiment, a fulcrum support 203 is fixedly installed in the middle of the adjacent surfaces of the first clamping plate 201 and the second clamping plate 202. The two sets of fulcrum support 203 are hinged to each other through a connecting shaft 204. Snap rings 205 are sleeved at both ends of the connecting shaft 204. A force plate 206 is fixedly installed on the upper edge of the second clamping plate 202, and a threaded top post 207 is screwed into the middle of the force plate 206.

[0025] In practice, two sets of retaining rings 205 apply clamping force to the lower edges of clamping plate 201 and clamping plate 202. This clamping force temporarily holds the entire device on the original sheet music holder. After adjusting the clamping position, the threaded top post 207 is rotated so that one end of the threaded top post 207 abuts against the inner surface of clamping plate 201. Using the connecting shaft 204 as a fulcrum, the continuous rotation replaces the elastic clamping force provided by the retaining rings 205 with the rigid clamping force of the threaded top post 207, which facilitates installation while ensuring stability during installation.

[0026] In this invention, motors 105, 110, and 112 are all servo motors, and the entire system is controlled by a PLC controller. When the foot pedal 3 is pressed, a signal is transmitted to the PLC controller built into the control box 107. The electromagnetic push rod 104 starts and retracts, pulling back the limit clamp 103 and releasing the restriction on the sheet music. Motor 110 starts, driving the rotating cantilever 111 to rotate, causing the rubbing wheel 113 to abut against the sheet music. After the rubbing wheel 113 is in place, motor 110 stops. Motor 112 starts, driving the rubbing wheel to rotate, using friction to rub the top layer of sheet music. When the sheet music page is turned over by the rubbing wheel 113 past the page-turning lever 106, motor 112 stops, the rubbing wheel 113 stops rotating, and motor 105 starts. The page-turning lever 106 is rotated counterclockwise to completely turn the sheet music to the other side, completing the page turn. The electromagnetic push rod 104 starts in the reverse direction, pushing the limit clamp 103 to reset and re-press the sheet music. At this time, the paper feed roller 113 contacts the next page. The first motor 105 continues to rotate counterclockwise, driving the page-turning lever 106 to rotate one full turn back to the initial position.
