Abstract

The utility model relates to a structure of timpani tuning pedal; wherein, an arc-shaped ratchet is fixed on the permanent seat of the inside of the swinging arm, a pawl meshed to the arc-shaped ratchet is arranged on the inside of the swinging arm, a swinging block hinged on the lower part of the pedal is fixed on the end of the pawl, a return spring is arranged on the other end of the installing swinging stem of the rotating shaft. The utility model has the advantages of rational design, resolving the disadvantage of no self-locking and self-reset in prior pedal art, raising the stability, accuracy, brilliantness and fluency, and making the performance go on wheels.

Description

Timpani tuning pedal structure

Technical field

The utility model belongs to the field of percussion instruments timpani, especially a kind of timpani tuning pedal structure.

Background technology

Timpani (TIMPANI) is one of percussion instrument more important in the philharmonic society, it also is the percussion instrument that is used in orchestra the earliest, bulging body and drum head by the semicircle spheroid are constituted, and in order to cooperate the needs of music, it can access the pitch of appointment in the melody via the pedal of particular design.Timpani can change pitch at once by after this pedal machines device tuning, obtains a semitone range completely, and can play big section continuous glide.Slam the pitch that pedal points to pointer to want during tuning, the rate of tension of adjusting drum head by the rotation of rotating shaft is carried out tuning to timpani simultaneously.Though existing pedal can carry out tuning at any time in performance, but there is also a lot of deficiencies: 1. pedal can not automatically revert to initial position after stepping on, can only be by manually pedal being taken up, give to play tuning and brought great inconvenience, and player's untimely performance rhythm of upsetting that may lift because of pedal; 2. after pedal arrives assigned address, rocking of health causes pedal to move up and down in the time of may playing owing to the player, and the drum head that makes timpani moves up and down its rate of tension constantly changed, thereby influences the accuracy of tuning, even has influence on the playing effect of whole performance.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and has auto-lock function and pedal can automatically reset timpani tuning pedal structure.

The utility model solves its technical matters and is achieved through the following technical solutions:

A kind of timpani tuning pedal structure, by pedal, swing arm, rotating shaft constitutes, the rotating shaft level is installed on the timpani holder, end in this rotating shaft installs swing arm, one end of this swing arm is installed fork, a connecting rod that pointer is installed on it is installed in the end of this fork, the other end installation foot pedal of swing arm, it is characterized in that: on the holder of swing arm inboard, be fixed with an arc ratchet, one ratchet that can be meshed with the arc ratchet is installed in the inboard of this swing arm, the tail end of this ratchet is fixed with a centering block that is fitted together with the bottom of pedal hinge, at the opposite side of the installation fork of rotating shaft one back-moving spring is installed.

And in the described ratchet suit one straight line guide rail, this line slideway and swing arm are solidly installed.

Advantage of the present utility model and beneficial effect are:

1. the ratchet of controlling by pedal meshes the arc ratchet that is solidly installed with holder, this ratchet can be contained on the arc ratchet by locator card after the tuning, make pedal can realize auto-lock function, the pedal of having avoided occurring owing to player's body-sway motion when playing moves up and down, thereby influences the phenomenon of drum head rate of tension.This ratchet ratch mechanism has increased stability and the accuracy when playing, and makes that playing effect is better, the performance process is more smooth.

2. the utility model is installed back-moving spring at an end of rotating shaft, effect by back-moving spring can make pedal lift automatically, realize auto-reset function, needn't with pin pedal be taken up again, make the player avoid taking place, guaranteed carrying out smoothly of performance because of the untimely phenomenon of playing rhythm of upsetting that pedal lifts.

3. the utility model is reasonable in design, solved the defective that present pedal does not have self-locking and auto-reset function well, has increased stability and accuracy when playing, makes that playing effect is better, the performance process is more smooth, and what guaranteed to play carries out smoothly.

Fig. 2 be Fig. 1 the omission timpani overlook enlarged drawing;

Fig. 3 is that the A of Fig. 2 is to enlarged diagram.

Embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

This timpani tuning pedal structure is the technological improvement to the pedal structure of existing timpani.Timpani is by drum body 3, drum body support frame 4, the holder 5 of drum body support frame is installed to be formed, the drum body support frame is packed on the crossbeam 8, between holder middle part and drum body, a spring 7 is installed, the tuning pedal structure is installed on the holder, its concrete formation is: rotating shaft 9 levels are installed on the holder of this timpani, end in this rotating shaft installs swing arm 14 by a fixed pin 17, one end of this swing arm is installed fork 11, a connecting rod 2 is installed in the end of this fork, pointer 1 is installed in the upper end of this connecting rod, the rotation that drives rotating shaft by fork realizes the rate of tension of timpani drum head is regulated, thereby realization tuning, the other end installation foot pedal 10 of this swing arm since above-mentioned be prior art, do not repeat them here.

Innovative point of the present utility model is: be fixed with an arc ratchet 16 on the holder of the inboard position of above-mentioned swing arm, one ratchet 12 that can be meshed with this arc ratchet also is installed in the inboard position of this swing arm, in this ratchet suit one straight line guide rail 13, this ratchet is realized rectilinear motion by the linear bearing in the line slideway 19; This line slideway be solidly installed by screw (not having label) and swing arm; Line slideway is also realized the guiding engagement of ratchet and arc ratchet by a setting-in screw 15.The tail end of ratchet is fixed with a centering block 18, and the bottom of this centering block and pedal hinge is fitted together, and is implemented in pedal and leans forward when stepping on, and its underpart is with perk backward, thereby the pulling centering block drives ratchet displacement backward, the disengagement of realization ratchet and arc ratchet; After pedal lifts, the spring of pedal bottom (not illustrating among the figure) will make pedal reply.Opposite side at the installation fork of rotating shaft is equipped with a back-moving spring 6.This back-moving spring is installed on the accordatura base 9 by holder, and pedal can be returned to initial position under the effect of back-moving spring, realize automatically reseting.

Principle of work of the present utility model is:

During performance, the leading section of pedal tramps with one's feet, withdraw with the ratchet that the arc ratchet is fastened, this moment, pedal can move up and down, rotating shaft is rotated under the drive of swing arm, and the drum head adjustment dish by spring pulling timpani moves up and down, and adjusts the drum head rate of tension, plays the effect of tuning; When rotating shaft was rotated, pointer also under the effect of fork, connecting rod, pointed to the corresponding pitch position of index dial.

After tuning finished, player's pin left the pedal front end, and ratchet stretches out and clamps and is positioned on the arc ratchet, realized the auto-lock function of pedal.
