Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, and particularly relates to a pedal assembly of a yangqin damper. Background Art

[0002] The yangqin is a multi-string musical instrument and is one of the main members of Chinese national musical instruments. Due to the advantages of being easy to learn, low in cost, and having a fresh and pleasant timbre, the yangqin has been loved by the broad masses of the people for a long time. The components of the yangqin mainly include a resonance box, a bridge, a string support, strings, string pins, tuning pegs, and bamboo hammers. In the yangqin with a traditional structure, after the strings are struck, the vibration time of the strings is long, causing the resonance box to resonate and sound. After the other instruments in the band stop sounding, only the yangqin has lingering sounds, resulting in a decline in the overall musical effect. When the performer finishes playing or there is an echo during the performance, the strings are pressed by hand to avoid excessive lingering sounds. However, on the one hand, this brings a lot of inconvenience to the performer, especially the performer using a yangqin with bass; on the other hand, it is also easy to have after-vibration and generate noise due to uneven pressing force.

[0003] To solve this problem, there has currently emerged a yangqin with a damping mechanism. For example, a damping yangqin disclosed in the Chinese Utility Model Patent with the publication date of October 5, 2011, and the publication number of CN202003660U, includes a piano body 1 and a damping mechanism. The surface of the piano body 1 is provided with a plurality of bridges 2 and a plurality of strings 3. The two ends of each string 3 are respectively fixed on the surface of the piano body 1, and each string 3 is pressed on the corresponding bridge 2. The damping mechanism includes two lower damping units, which are the first lower damping unit 4 and the second lower damping unit 6 respectively. The first lower damping unit 4 and the second lower damping unit 6 are respectively located on the left and right sides of the piano body 1. The first lower damping unit 4 includes a first damping plate 401, a first lower damping plate positioning mechanism 404, and a first lower damping driving mechanism 403. The first damping plate 401 is fixed on the first lower damping plate positioning mechanism 404, the first lower damping plate positioning mechanism 404 is fixed on the piano body 1, and the first lower damping driving mechanism 403 is connected to the first damping plate 401. The first lower damping driving mechanism 403 includes a transmission mechanism and a driving member. The driving member is connected to the damping plate 401 through the transmission mechanism. The transmission mechanism is a pull rope, and the driving member is a pedal. The upper end of the pull rope is connected to the damping plate, and the lower end is connected to the pedal. However, this damping yangqin still has the following disadvantages in actual use: Since the pedal is suspended on the pull rope, it is easy to shake, resulting in an unstable position when it is stepped on, affecting the performer's control of the damping mechanism, and thus affecting the playing effect of the yangqin. Summary of the Utility Model

[0004] The technical problem to be solved by the present utility model is to provide a pedal assembly for a dulcimer damper. This pedal assembly enables the performer to control the action of the damping mechanism by stepping on it, which is convenient to operate and has a good damping effect, and can ensure that its position is relatively stable when being stepped on, which is beneficial to ensuring the performance effect of the dulcimer. The adopted technical solution is as follows:

[0005] A pedal assembly for a dulcimer damper, including a foot pedal, characterized in that: it further includes a bottom plate, a bracket, an elastic connecting member and a heel support member. The bracket is installed on the middle and rear section of the bottom plate; the foot pedal is arranged on the upper side of the bottom plate, and the middle section of the foot pedal is hinged on the bracket. The front end of the foot pedal is connected to the rear end of the bottom plate or the bracket through an elastic connecting member; the heel support member is arranged on the front side of the bottom plate and is connected to the front end of the bottom plate.

[0006] The above-mentioned dulcimer damper may include at least one damping unit. The damping unit includes a damping plate and a damping plate driving mechanism capable of driving the damping plate to rotate. The upper and lower ends of the damping plate are respectively rotatably arranged on the surface of the dulcimer body, and the damping plate is located below the strings. A plurality of damping cottons are arranged in sequence from front to back on one side of the damping plate; the damping plate driving mechanism includes a transmission mechanism and a driving member. The driving member is connected to the damping plate through the transmission mechanism. The transmission mechanism is a pull rope, and the driving member is the above-mentioned pedal assembly. The upper end of the pull rope is connected to the damping plate, and the lower end of the pull rope is connected to the front end of the foot pedal of the above-mentioned pedal assembly.

[0007] During use, the bottom plate of the above-mentioned pedal assembly is placed flat on the ground and directly below the dulcimer body. The performer can place the heel on the heel support member and rest the front part of the sole on the rear part of the foot pedal; when damping is required, the performer only needs to step on the front end of the foot pedal downward with the front part of the sole, so that the rear end of the foot pedal swings upward around its hinge with the bracket (at this time, the elastic connecting member is stretched and deformed), thereby driving the corresponding damping plate to swing through the damping plate driving mechanism, so that each damping cotton contacts the corresponding string respectively, and the string is stabilized to achieve damping; when damping is not required, the performer lifts the front part of the sole upward, and the elastic connecting member will retract and return to its original state, so that the rear end of the foot pedal swings downward around its hinge with the bracket under the action of the elastic connecting member to reset, thereby driving the corresponding damping plate to swing in the reverse direction through the pull rope of the damping plate driving mechanism, so that each damping cotton separates from the corresponding string respectively, and the front end of the foot pedal can easily and effectively support the performer's foot, so that it can be stepped on at any time. The touch of lightness and heaviness (depth) is beneficial to making full use of the aftersound of the dulcimer, so as to effectively control the strength of the foot to meet the performance effect. Moreover, by arranging the heel support member on the front side of the bottom plate to support the performer's heel, the downward acting force applied by the performer can be utilized to make it not easy to move, so as to ensure that the overall position of the pedal assembly is relatively stable.

[0008] As a preferred solution of the utility model, the heel support member adopts a support plate, and the rear end of the support plate is connected to the front end of the bottom plate, thereby increasing the contact area between the heel support member and the player's heel, and further improving the stability of the overall position of the pedal assembly.

[0009] As a further preferred embodiment of the present invention, the rear end of the lower support plate is hinged to the front end of the base plate via a hinge. When it is necessary to carry or store, the lower support plate can be flipped down around the hinge to a position that fits the bottom surface of the base plate, thereby reducing the overall length of the pedal assembly and making it easier to store and carry.

[0010] As a further preferred embodiment of the present invention, the lower support plate, the bottom plate, and the foot pedal are all made of the same material. This makes the appearance of the pedal assembly more beautiful and elegant. The lower support plate, the bottom plate, and the foot pedal can be made of wood, plastic, or metal (such as iron or stainless steel).

[0011] As another preferred embodiment of the present invention, the heel support member is a rope, one end of which is connected to the front end of the base plate. When in use, the performer can press the heel on the rope and then step down the front end of the pedal with the front of the sole, which is more convenient to use.

[0012] As a preferred solution of the utility model, the elastic connecting member includes a connecting bolt and a tension spring, the lower end of the screw of the connecting bolt is installed on the rear end of the bracket or the bottom plate, the lower end of the tension spring is connected to the head of the connecting bolt, and the upper end of the tension spring is connected to the front end of the foot pedal. When the front end of the foot pedal is stepped down by the front of the sole of the player, the tension spring is stretched and deformed by the rear end of the foot pedal; when the player lifts the front of the sole of the foot, the tension spring returns to its original state, driving the rear end of the foot pedal to swing upward and reset.

[0013] As a further preferred embodiment of the present invention, a compression spring is sleeved on the screw rod of the connecting bolt, and the lower end and upper end of the compression spring are in close contact with the bracket and the lower end of the tension spring respectively. The compression spring can exert an upward force on the lower end of the tension spring, so that the connection between the lower end of the tension spring and the head of the connecting bolt is tightened.

[0014] As another preferred embodiment of the present invention, the elastic connecting member includes a connecting ring and a tension spring, the connecting ring is fixed on the rear end of the base plate or the bracket, the lower end of the tension spring is connected to the connecting ring, and the upper end of the tension spring is connected to the front end of the foot pedal. When the front end of the foot pedal is stepped down by the front of the sole of the player, the tension spring is stretched and deformed under the drive of the rear end of the foot pedal; when the player lifts the front of the sole of the foot, the rear end of the foot pedal swings and resets under the reset action of the tension spring.

[0015] As a preferred embodiment of the present utility model, a widened portion is provided at the front section of the foot pedal. Thereby, the contact area between the front section of the foot pedal and the front part of the performer's foot can be increased, facilitating the performer to apply a force to the foot pedal through the foot.

[0016] As a specific embodiment of the present utility model, the bracket is made of a metal bracket; the base plate and the foot pedal are made of wood. Thereby, the overall structure of the pedal assembly can be made more stable and aesthetically pleasing.

[0017] Compared with the prior art, the present utility model has the following advantages:

[0018] (1) This kind of pedal assembly can easily and effectively support the performer's foot, which is beneficial to the tactile sensation of the foot, so as to be ready to step down in time at any time. The tactile sensation of light and heavy (shallow and deep) is beneficial to the full utilization of the aftersound of the sound piano, thereby effectively controlling the strength of the foot to meet the performance effect;

[0019] (2) This kind of pedal assembly is provided with a heel support component on the front side of the base plate for supporting the performer's heel. Thereby, during performance, the downward force applied by the performer can be used to make it not easy to move, so as to ensure that the overall position of the pedal assembly is relatively stable, easy to control, and has high practicability; moreover, the heel support component can adopt a rear support plate, and the rear end of the rear support plate and the front end of the base plate can be hinged through a hinge. Thereby, when carrying or storing, the lower support plate can be turned downward around the hinge to fold to a position that fits the bottom surface of the base plate, so as to reduce the overall length of the pedal assembly, which is easy to store and convenient to carry.

[0024] As Figures 1-4As shown, the pedal assembly 100 of this dulcimer damper includes a bottom plate 1, a bracket 2, a foot pedal 3, an elastic connecting member 4, and a lower support plate 5. The bracket 2 is installed on the middle and rear section of the bottom plate 1; the foot pedal 3 is arranged on the upper side of the bottom plate 1. The middle section of the foot pedal 3 is hinged to the bracket 2, and the front end of the foot pedal 3 is connected to the rear end of the bottom plate 1 through the elastic connecting member 4; the lower support plate 5 is arranged on the front side of the bottom plate 1, and the rear end of the lower support plate 5 is hinged to the front end of the bottom plate 1 through a hinge 51.

[0025] In this embodiment, the bracket 2 is made of a metal bracket 2 (such as a stainless steel bracket); the materials of the bottom plate 1, the foot pedal 3, and the lower support plate 5 are made of wood. Thus, the overall structure of the pedal assembly 100 can be more stable and aesthetically pleasing.

[0026] In this embodiment, the elastic connecting member 4 includes a connecting bolt 41 and a tension spring 42. The lower end of the screw of the connecting bolt 41 is installed on the rear end of the bottom plate 1. The lower end of the tension spring 42 is connected to the head of the connecting bolt 41, and the upper end of the tension spring 42 is connected to the front end of the foot pedal 3; a compression spring 43 is sleeved on the screw of the connecting bolt 41, and the lower end and the upper end of the compression spring 43 are in close contact with the bracket 2 and the lower end of the tension spring 42 respectively.

[0027] In this embodiment, a widened portion 31 is provided at the front section of the foot pedal 3. Thus, the contact area between the front section of the foot pedal 3 and the front part of the performer's foot sole can be increased, which is convenient for the performer to apply a force to the foot pedal 3 through the foot.

[0028] The following briefly describes the usage method of the dulcimer damper with this pedal assembly 100:

[0029] The dulcimer damper includes at least one damping unit. The damping unit includes a damping plate and a damping plate driving mechanism capable of driving the damping plate to rotate. The upper and lower ends of the damping plate are respectively rotatably arranged on the surface of the instrument body, and the damping plate is located below the strings. A plurality of damping cottons are arranged in sequence from front to back on one side of the damping plate; the damping plate driving mechanism includes a transmission mechanism and a driving member. The driving member is connected to the damping plate through the transmission mechanism. The transmission mechanism is a pull rope 200, and the driving member is the pedal assembly 100. The upper end of the pull rope 200 is connected to the damping plate, and the lower end of the pull rope 200 is connected to the front end of the foot pedal 3 of the pedal assembly 100.

[0030] During use, the bottom plate 1 of the pedal assembly 100 lies flat on the ground and is directly below the dulcimer body; the player can place the heel on the lower support plate 5 and rest the front part of the sole on the rear part of the foot pedal 3. When damping is required, the player only needs to step down on the front end of the foot pedal 3 with the front part of the sole, causing the rear end of the foot pedal 3 to swing upward around its hinge with the bracket 2 (at this time, the tension spring 42 undergoes tensile deformation under the pull of the rear end of the foot pedal 3). Thus, the corresponding damping plate is driven to swing through the pull rope 200 of the damping plate driving mechanism, causing each damping cotton to contact the corresponding strings respectively, and stabilizing the strings to achieve damping; when damping is not required, the player raises the front part of the sole upward, and the tension spring 42 will retract to its original state, causing the rear end of the foot pedal 3 to swing downward and reset around its hinge with the bracket 2 under the pulling force of the tension spring 42. Thus, the corresponding damping plate is driven to swing in the opposite direction through the pull rope 200 of the damping plate driving mechanism, separating each damping cotton from the corresponding strings respectively. Moreover, the front end of the foot pedal 3 can easily and effectively support the player's foot, so that the player can step on it at any time. The light and heavy (shallow and deep) touch is conducive to making full use of the lingering sound of the dulcimer, thus effectively controlling the strength of the foot to meet the performance effect. And by providing the lower support plate 5 on the front side of the bottom plate 1 to support the player's heel, the downward force applied by the player can be used to make it not easy to move, ensuring the overall position of the pedal assembly 100 is relatively stable. When it is necessary to carry or store the dulcimer damper, the lower support plate 5 can be turned downward and folded around the hinge 51 to a position where it fits against the bottom surface of the bottom plate 1, thereby reducing the overall length of the pedal assembly 100 and making it easy to store and carry.
