Abstract

PURPOSE: To provide a beater for drums with which two kinds of sound quality are selectively obtainable and also the timbres of two kinds of the sound quality are selected respectively in two ways. CONSTITUTION: A beater head 32 is formed of a head having four drum percussion surfaces A1 to A4. Two drum percussion surfaces A1, A3 among these surfaces are formed as transversely curving percussion surfaces having a budge curving in the peripheral direction of a shaft 31 and the other two percussion surfaces A2, A4 are formed as longitudinally curving percussion surfaces having a bulge curving in the axial direction of the shaft 31. The one A3 of the two transversely curving percussion surfaces and one A4 of the two longitudinally curving percussion surfaces are formed of soft materials. The other transversely curving percussion surface A1 and longitudinally curving percussion surface A2 are formed of materials harder than soft materials.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum beater and a drum pedal.

[0002]

2. Description of the Related Art A bass drum among various drums constituting a drum set is played by a drum pedal.

This drum pedal comprises a footboard, a rotary shaft which is rotated by the depression of the footboard and is returned and rotated by a spring force, and a beater which is attached to a beater holder provided on the rotary shaft. As the beater, generally, a beater head having a short cylindrical shape made of a compression-molded felt is attached to the tip of a shaft whose base end is detachably fixed to the beater holder.

[0004]

However, the conventional drum pedal using the beater described above can add or subtract the strength of the footboard to the performance sound, but its sound quality and tone are It couldn't be changed.

It is an object of the present invention to provide a drum beater and a drum pedal which can selectively obtain two kinds of sound quality and can select two kinds of tone colors of the two kinds of sound quality. It was done.

[0006]

In the beater according to the present invention, a beater head attached to the tip of a shaft has four drum striking faces in front, rear, left and right with respect to the shaft, and two drum striking faces are included. Is a laterally curved striking surface having a bulge that is curved in the circumferential direction of the shaft, and the other two drum striking surfaces are vertical curved striking surfaces that have bulges that are curved in the axial direction of the shaft.
One of the two lateral curved surface and one of the two vertical curved surfaces are made of a soft material, and the other lateral curved surface and the longitudinal curved surface are made of a material harder than the soft material. It is characterized by.

The drum pedal of the present invention comprises a footboard, a beater holder which is rotated by the depression of the footboard and is returned and rotated by a spring force, and a beater which is attached to the beater holder. It is characterized in that the one having the four drum hitting surfaces is used.

In the drum pedal according to the present invention, a stopper which is received by the beater holder and defines the mounting height of the beater is provided on the base end side of the shaft of the beater, and one of the stopper and the beater holder is provided. Is formed with four positioning surfaces respectively corresponding to the orientations of the four drum striking surfaces of the beater head, and on the other hand, a beater posture defining surface that selectively comes into contact with the positioning surface to regulate the mounting posture of the beater. Those provided with are desirable.

[0009]

The beater of the present invention is used by arbitrarily selecting one of the four drum striking surfaces of the beater head and is formed of a soft material of the four drum striking surfaces. If you select a striking surface that has a soft playing sound,
Selecting a striking surface made of a hard material produces a hard playing sound. Also, if you select a laterally curved striking surface that has a bulge that bends in the circumferential direction of the shaft, this striking surface hits the drum head in a point contact state and a normal attack tone is obtained, and the curved surface is curved in the axial direction of the shaft. When a vertically curved striking surface with a bulge is selected, this striking surface hits the drum head in line contact with the striking sound to enhance the striking sound, and a strong attack sound is obtained.

In this beater, of the four drum hitting surfaces of the beater head, one of the two laterally curved hitting surfaces and one of the two longitudinally bowing hitting surfaces are made of a soft material, and the other laterally bowing hit is formed. Since the surface and the vertically curved striking surface are formed of a material that is harder than the soft material, one of these striking surfaces is arbitrarily selected to play the drum, thereby producing a soft sound and a hard sound. It is possible to selectively obtain two types of sound quality, and to select two tones of these two types of sound quality.

Since the drum pedal of the present invention uses the beater, one of the four drum striking surfaces of the beater head is arbitrarily selected and the striking surface is directed to the drum. By attaching the beater to the beater holder and playing the drum, the above-mentioned two kinds of sound quality can be selectively obtained, and two kinds of tone colors can be selected respectively.

Further, in the drum pedal of the present invention, a stopper which is received by the beater holder and defines the mounting height of the beater is provided on the proximal end side of the shaft of the beater, and one of the stopper and the beater holder is provided. Forming four positioning surfaces respectively corresponding to the orientations of the four drum hitting surfaces of the beater head, and on the other,
If a beater posture defining surface that selectively contacts the positioning surface and defines the mounting posture of the beater is provided, the mounting posture of the beater can be changed by bringing the positioning surface into contact with the beater posture defining surface. Since it can be regulated, it is possible to easily attach the beater that is attached to the beater holder with any one of the four drum striking surfaces facing the drum.
