Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a drum pedal in which a beater support frame and a rear piece are connected by a base plate.

[Conventional technology]

Drum pedal for playing bass drum
A beater support frame, a beater attached to a rotating shaft provided on the beater supporting frame, a rear piece separate from the beater supporting frame, a base end pivoted to the rear piece, and a distal end connected to the rotating shaft. The beater support frame and the rear piece are generally connected at the base end to the rear piece and removably connected to the beater support frame at the distal end. They are connected by connecting rods.

FIG. 4 shows a conventionally known drum pedal, in which numeral 1 represents a beater support frame. This beater support frame 1 has pillars 1b erected on both sides of its base 1a.
The beater support frame 1 includes a hoop receiving portion 1c which is formed by pressing the lower edge of a drum head support hoop (not shown) of the bass drum from its inner peripheral surface so that the hoop protrudes in front of the frame base 1a. A hoop clamp member 2 that is clamped and fixed between the two is pivotally supported. Note that 3 is a hoop clamp screw for pressing the hoop clamp member 2 against the hoop. Further, 4 is a beater that hits the drum head on the bass drum, and this beater 4 is rotatably supported at both ends by the upper ends of both columns 1b of the beater support frame 1, and is attached to a rotating shaft 5 provided horizontally. It is being Reference numeral 6 is a footboard for rotating the beater 4 in the front-back direction to perform drum performances;
The base end of the footboard 6 is pivotally supported by a rear piece 7, which is separate from the beater support frame 1, so as to be rotatable in the vertical direction. The tip of the footboard 6 is connected to the other end of a connecting body 8 consisting of a belt or chain whose one end is wrapped around a fan-shaped footboard connecting portion 5a provided on the rotation shaft 5. The leading end side is suspended and supported by this connecting body 8. Although not shown, there is a beater return spring on the side of the beater support frame 1, which is connected to a clamp member provided at the end of the rotating shaft 5 and rotates the beater 4 back in the direction away from the drum. When the foot board 6 is stepped on, the beater 4 is rotated toward the drum side together with the rotating shaft 5 and hits the drum head. When the foot board 6 is removed, the beater 4 is returned to its original position by the spring force of the beater return spring. At the same time, the footboard 6 is returned upward.

Reference numeral 9 designates two left and right connecting rods that connect the beater support frame 1 and the rear piece 7 and maintain the distance between them. 1
It is removably fitted into a connecting rod attachment portion 1d formed on the support column 1b.

The bass drum is assembled by fitting the tip of the connecting rod 9 into the connecting rod attachment part 1d of the beater support frame 1 when setting the drum pedal, and when transporting the bass drum, the connecting rod 9 is removed from the beater support frame 1. It is transported in a disassembled state, and by removing the connecting rod 9 from the beater support frame 1, the footboard 6 and rear piece 7 can be folded onto the front side of the beater support frame 1.
The overall size of the drum pedal can be reduced and transported.

However, in the drum pedal in which the beater support frame 1 and the rear piece 7 are connected by the connecting rod 9 as described above, the connecting rod 9 only has the function of maintaining the distance between the beater supporting frame 1 and the rear piece 7. As a result, the entire drum pedal wobbled when the footboard 6 was depressed.

For this reason, recently, instead of the connecting rod 6,
A base plate 10 as shown by chain lines in FIG. 4 that is in flat contact with the floor surface is used, and the bottom surface of the beater support frame 1 and the bottom surface of the rear piece 7 are brought into contact with the top surface of both front and rear ends of the base plate 10, and screws are attached to the bottom surface of the beater support frame 1 and the bottom surface of the rear piece 7, respectively. It is considered that the beater support frame 1 and the rear piece 7 are connected by the base plate 10 by fixing them. If the beater support frame 1 and rear piece 7 are fixed to
It is possible to prevent the drum pedal from wobbling when the footboard 6 is depressed, and to perform the drum performance in an easy-to-play condition.

[Problem that the invention attempts to solve]

However, when connecting the beater support frame 1 and the rear piece 7 by the base plate 10, conventionally the beater support frame is also fixed to the base plate 10 with screws as described above.
The base plate 10 cannot be removed from the beater support frame 1 unless the screws that are fixed to the beater support frame 1 are removed, and since the beater support frame 1 is screwed to the base plate 10 at several locations on the bottom of the beater support frame 1, all of the Since it is not easy to remove the screws, the conventional drum pedal, in which the beater support frame 1 and the rear piece 7 are connected by the base plate 10, has the problem that it has to be transported in an assembled state.

This idea was made in view of the above-mentioned circumstances, and its purpose was to connect the base of the beater support frame and the rear piece with a base plate to prevent the drum pedal from wobbling. To provide a drum pedal whose base plate can be easily removed from a beater support frame and the entire drum pedal can be transported in a reduced size state.

[Means to solve problems]

In order to solve the above-mentioned problems, this invention has the front end of a base plate whose rear end is fixed to the bottom of the rear piece come into contact with the upper surface of the base of the beater support frame so that it can come into contact with and separate from the top of the base of the beater support frame. A frame clamp mechanism is provided that is pressed and fixed to the front end of the facing base plate.

[Effect]

That is, in the drum pedal of this invention, instead of screwing the front end of the base plate to the bottom of the beater support frame, the frame clamp mechanism is provided on the front end of the base plate, and the base of the beater support frame is fixed by this frame clamp mechanism. The beater support frame is fixed to the base plate by pressing against the front end of the base plate, and according to this drum pedal, the base plate can be removed from the beater support frame simply by releasing the frame base from the frame clamp mechanism. Although the base plate of the beater support frame and the rear piece are connected by the base plate to prevent the drum pedal from wobbling, the base plate can be easily removed from the beater support frame to reduce the overall size of the drum pedal. It can be transported in a small size.

〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 to 3, 1 is a beater support frame. Since this beater support frame is the same as the conventional beater support frame shown in FIG. 4, description of each part will be omitted by assigning the same reference numerals to the figure. Reference numeral 10 denotes a base plate made of a metal plate.The rear end of this base plate 10 is fixed with screws to the bottom surface of the rear piece 7 shown in FIG. It is shaped so that it is in contact with almost its entire surface. In addition, in FIG. 2, reference numeral 11 indicates anchor bolts for preventing slips, which are conventionally provided on both sides of the frame base 1a of the beater support frame 1.
The base plate 10 is shaped to be in contact with the bottom surface of the beater support frame 1, avoiding the anchor bolts 11. On the other hand, 12 is the base plate 1
This is a frame clamp mechanism provided on the upper surface of the front end side of the beater support frame 1, avoiding the contact part of the beater support frame 1. This frame clamp mechanism 12 contacts the upper surface of the base of the beater support frame 1 so as to be able to move toward and away from it, and presses and fixes the frame base 1a to the front end of the base plate that is in contact with the bottom surface of the frame base 1a. It is said to have a structure like this. That is, in FIGS. 1 to 3, 1
A bracket 3 is fixed to the upper surface of the base plate 10 by a rivet 14, and the base end of a clamp arm 15 is pivotally supported at the front end of this bracket so as to be rotatable in the vertical direction. The clamp arm 15 has a horizontal L-shape that rises slightly upward from its bracket pivot point and extends from its upper end toward the beater support frame 1. An attachment 16 is attached that comes into contact with the inclined surface of the upper surface of the frame base 1a. Note that this attachment 16 is made of hard rubber. Further, reference numeral 17 designates a rotating arm whose lower end is pivotally supported on the rear end of the bracket so as to be rotatable in the front-rear direction, and reference numeral 18 designates a clamp operation lever that can be manually moved up and down. The distal end is pivotally attached to the bent portion of the L-shaped clamp arm 15, and the rotating arm 17 is tilted from its bracket pivot portion toward the clamp arm 15, and an operating lever 18 is attached at its upper end.
It is pivotally attached to the middle part of.

This frame clamp mechanism 12 rotates a clamp arm 15 up and down by operating the operating lever 18 to bring an attachment 16 at its tip into contact with and away from the upper surface of the frame base 1a. When the knob 18a formed at the base end of the operating lever 18 is pushed down with the support frame 1 placed on it,
The rotating arm 17 tilted toward the clamp arm 15 rotates further forward, and the operating lever 18 moves toward the distal end, and the clamp arm 15 is pushed by the operating lever 18 and moves forward as shown in FIG. Since it rotates downward, the attachment 16 at the tip of the clamp arm 15 can be pressed against the upper surface of the frame base 1a, and the frame base 1a can be pressed and fixed to the front end of the base plate. In addition, in this embodiment, since the attachment 16 of the clamp arm 15 is brought into contact with the inclined surface of the upper surface of the frame base 1a, there is a risk that the beater support frame 1 may shift forward. In the example, a stopper 19 is provided at the front end of the base plate 10 to receive the front end surface of the frame base 1a, for example, the front end surface of the hoop receiver 1c, from the front.
This prevents the beater support frame 1 from shifting forward. Further, the rotation arm pivot point A of the operating lever 18 is such that when the operating lever 18 is pushed down until the attachment 16 of the clamp arm 15 comes into contact with the upper surface of the frame base 1a with sufficient pressing force, the operating lever 18 is rotated. It is located on the straight line a connecting the clamp arm pivot point B and the pivot point O of the pivot arm 17, or at a position slightly closer to the clamp arm 15 than the straight line a. 18 is pressed down, the clamp arm 15 and the operating lever 18 do not return even if a pressing reaction force from the frame base 1a acts on the distal end side of the clamp arm 15. Therefore, the frame clamp mechanism 12 moves the frame base 1a to the base plate. It is locked when pressed against the front end.

Furthermore, when removing the base plate 10 from the beater support frame when transporting the drum pedal, etc., it is sufficient to pull up the knob 18a of the operating lever 18.
When a is pulled up, the pivot point A of the operating lever 18 moves beyond the straight line a to the operating lever 18 side due to the rearward rotation of the rotating arm 17, and the lock of the frame clamp mechanism 12 is released. At the same time, the operating lever 18 moves toward the proximal end due to the rearward rotation of the rotating arm 17, and the clamp arm 15 is pulled by the operating lever 18 and rotates forward and upward as shown in FIG. Then, the fixation of the beater support frame 1 can be released by separating the attachment 16 at the tip of the clamp arm 15 from the frame base 1a. Since the beater support frame 1 is placed on the base plate 10 and its base 1a is only held and fixed by the frame clamp mechanism 12, it is necessary to release the frame base 1a from being pressed by the frame clamp mechanism 12. If so, it can be immediately removed from the base plate 10.

Therefore, in the drum pedal, instead of screwing the front end of the base plate 10 to the bottom surface of the beater support frame 1 as in the conventional case, the frame clamp mechanism 12 is provided on the front end side of the base plate 10, and the frame clamp mechanism 12 is provided on the front end side of the base plate 10. The mechanism 12 presses the base 1a of the beater support frame 1 against the front end of the base plate to fix the beater support frame 1 to the base plate 10. According to this drum pedal, the frame clamp mechanism 12 presses the base 1a of the beater support frame 1 against the front end of the base plate. The base plate 10 can be removed from the beater support frame 1 by simply releasing the pressure on the base 1a, and therefore the base of the beater support frame 1 and the rear piece are connected by the base plate 10 to prevent the drum pedal from wobbling. However, the base plate 10 can be easily removed from the beater support frame 1, and the base plate 10, footboard, and rear piece can be folded up on the front side of the beater support frame 1, and the drum pedal can be transported while reducing its overall size. be able to.

In the above embodiment, a stopper 19 is provided at the front end of the base plate 10 to prevent the beater support frame 1 from shifting forward. This may be prevented by making the pressing surface by the clamp arm 15 a horizontal surface, or by providing a recess in the pressing surface into which the attachment 16 at the tip of the clamp arm fits, in which case the stopper 19 may be omitted. Further, in the above embodiment, the frame clamp mechanism 12 is configured to move the frame base 1a toward and away from the frame base 1a by lever operation, but this frame clamp mechanism is not limited to the above embodiment. A structure may be employed in which a member is fixed to the base plate 10 and a clamp bolt with a handle that is tightened to the upper surface of the frame base 1a is threaded and inserted into the member.

[Effect of idea]

The drum pedal of this invention has a base plate whose rear end is fixed to the bottom of the rear piece, and a
Since a frame clamp mechanism is provided that detachably abuts on the upper surface of the base of the beater support frame and presses and fixes the frame base to the front end member of the base plate that is in contact with the bottom surface of the frame base, the base of the beater support frame and the rear piece are Although the drum pedal is connected by a base plate to prevent the drum pedal from wobbling, the base plate can be easily removed from the beater support frame and the drum pedal can be transported in a state where the overall size of the drum pedal is reduced.
