Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a beater device for a drum in which the hit surface is located substantially vertically, and a rate John mechanism is added to the Peter Rotz r that rotates in conjunction with the stepping motion of the foot (darle). Additionally, the beater can improve the followability of the foot pedal when playing string sounds or soft notes.

Conventionally, this type of beater device is shown in Fig. 1 and Fig. 2.
As illustrated in the figure, a rotation shaft 2 is pivotally supported on a pedal frame l, and a beater rod 4 to which a beater 3 is attached is hard-soldered to the rotation shaft 2 at a desired angle.
The rotation shaft 2 is rotated in conjunction with the stepping motion (in the direction of the solid line arrow) of the 7 I and J darts 7 via the belt locker 5 and the belt 6, while the rotating shaft 2 is rotated by the stepping motion of the foot 7 (in the direction of the solid arrow). A device is known in which a rotating shaft 2 is rotated back to its original position by a cam plate 8 and a spring 9.

However, in this type of conventional structure, when the drum is played by hitting the surface to be hit, the return of the Peter rod 4 after hitting is maintained by the biasing force of the spring 9. Since the return force (reaction force) of the beater rod is not a uniform acceleration motion, it does not match the ergonomics of the player's stepping sensation, and when the biasing force of the spring is increased, the beater rod
The return of the rod is faster, which is effective for playing soft notes, but on the other hand, the reaction force when stepping on the drum is strong, and playing with string sounds requires a stronger stepping force than is natural. If the biasing force of the spring is weakened, it becomes easier to press the foot pedal, but there are various disadvantages, such as the inability to follow soft notes where the reaction force of the Peter rod is slow, especially soft notes with a fast tempo.

This invention aims to eliminate the drawbacks of the conventional structure described above, and will be explained based on an embodiment shown in FIG.

As shown in Figure 3, the number 10 in Figure 1 is a beater rod, the lower end of which is a fixed beater 12 that forms the pedal frame.
is attached to the drum's hit surface DK, which is located perpendicularly to the rotation shaft 14 that rotates in conjunction with the depression of the one-foot pedal 13 via an action mechanism to be described later.
The direction can be driven and rotated in the front-back direction. Further, a timing rocker 1 is provided at the shaft end of the rotation shaft 14.
A belt 1 is mounted between the timing rocker 15 and the swinging end 14 & of the foot pedal 13.
By passing 6, the rotation shaft 14 is rotated in the counterclockwise direction in conjunction with the depression operation of the foot pedal 13 (indicated by the solid line arrow), while the combination members constituting the action mechanism, etc. The trap is such that it rotates in the opposite direction due to its own weight and returns to its original position.

That is, the action mechanism for driving and rotating the beater rod 1o described above employs a hammer quick-return mechanism (repetition mechanism) in the so-called string-striking mechanism of an upright piano, and is controlled by the depression operation of the foot pedal 13. One end 17 of the light twin 17 is attached to the rotation shaft 14 that is linked to the
A is fixed in a horizontal state, and a balance weight 18 is suspended from the other free end 17b of the right twin 17, and a base 19 of an abbreviated jack 19 is installed in the middle part.
While pivoting the jack 19, one end 2 of the jack 19 is brought into contact with the pushing up sliding surface 11a of the eyelet 1, and the rotation axis 1 is rotated when the foot pedal 13 is depressed.
The beater rod 10 is rotated in the driving direction by rotating the right twin 17 upward with the rotation of step 4 and at the same time pushing up and rotating the putt 11 at the push-up end 19 m) of the shack 19. It has the following configuration. In addition, in the figure, a spring 21 biases the Peter rod 100 in a rotational direction that opposes the driving direction, and 21 a raised end 191) of the jack 19 on the sliding surface 11 of the pad 11.
A compression spring n is located opposite the other end 19c of the jack 19 and urges the jack 19 to always be in contact with the right twin 17 at a predetermined lifting operation position. A regulation that separates the raised end 19b of the jack 19 from the sliding surface 11a of the pad 11 so as to release the rotating operation of the repeater rod 100 by rotating it against the biasing force of the compression spring 21. button, free end 171 of the light twine 17)
K is erected, and by receiving and stopping the pad 11 at its tip, a pack check is performed to regulate the return position of the Peter rod 10 during operation, and furthermore, the final return of the beater and rod 10 is controlled. Beater that regulates the position
It is a rest.

Furthermore, reference numeral 5 in the figure is a damper rod which is linked to the stepping motion of the foot pedal 13, and has a damper 3 attached to its tip. The bolt 14-rod 5 is provided so as to be rotatable in the front and back direction via a rocker n pivotally supported on a fixed base, and is supported by the biasing force of a spring. The rocker n is designed so that it can always contact and press the hit surface of the drum before the depression of the foot pedal 13, and the rocker n is hung via the bell 29 on the rotation shaft 14 which rotates when the one-foot pedal 13 is depressed. By interlocking the movement, the drum is separated from the striking surface of the drum when the foot pedal 13 is depressed.

Next, to explain the operation of the Peter device according to the present invention, when the foot pedal 13 is depressed during a performance, the pivot shaft 14 is rotated counterclockwise via the belt 16 and the timing rocker 15 due to the rocking of the core pedal. Rotate in the direction, Light Twin 1
At the same time as the damper rod 7 rotates upward, the damper rod also rotates backward (clockwise) via the rocker n and the belt 4, thereby separating the damper rod from the struck surface of the drum. Then, the jack 19 and the pack check n also rise due to the upward rotation of the right twin 17, and the raised end 19t) of the jack 19 is rotated so as to push up the sliding surface 11a of the pad 11, and the tip A Peter rod 10 having a Peter 12 at its end is driven forward into the striking surface of the drum and rotated (counterclockwise). At this time, when the jack 19 rises to a predetermined position, the other end 19c
The regulating member comes into contact with the tongue ρ, and the jack 19 is rotated clockwise against the biasing force of the compression spring 21.
The thrusting and rotating operation of the thrusting end portion 19b toward the pad 11 is released. Peter rod 10 immediately after opening is
Due to inertia, it further rotates in the forward driving direction, and as soon as the Peter 12 at its tip hits the hit surface of the drum, it rotates backward due to the reaction force, and it hits the pack check n located close to it. It instantly returns to the contact position. When the foot pedal 13 is depressed in this state, the rotation shaft 14 is moved by the weight of the Peter rod 10, the Peter 12, the right twin 17, the balance weight 18, the jack 19, the pack check n, etc. that make up the action mechanism. It quickly rotates in the rotational direction and returns to the initial operating position to enable the next striking action.

In the above embodiment, the damper 26 is configured to always press the hit surface of the drum before the foot pedal 13 is depressed, and to separate from the hit surface as the foot pedal 13 is depressed. For example, the foot pedal 13 can be depressed stepwise (for example, in two steps), and the first depression of the foot pedal 13 rotates the civitar rod 10, and the second depression k.
It is also possible to press the damper 4% on the drum's hit surface DK, and with such a configuration, it is possible to add a mute effect at an appropriate point during drum performance.

As explained above, 1. According to the configuration of the present invention, since the action mechanism of the Peter rod is provided with a repetition mechanism that constitutes a string-striking device in an upright piano, the Peter rod immediately after a striking action is The ball is stopped by the puck check, and the ball can quickly return to the initial striking position by following the puck check action, making it possible to perform the next striking action without having to fully return the foot pedal. , it becomes easier to play with a fast balance or play with a weak tone. This also expands the performance range from soft tones (piano) to stringed tones (forte), making dynamic performance possible. Furthermore, by providing a foot that is linked to the stepping motion of the drum, it is possible to not only obtain a crisp sound without using a mute that constantly presses the drum's hit surface as in the past. This has excellent practical effects, such as being able to improve the so-called "single-note jam" caused by a permanent mute.
