ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a foot pedal for beating the drum head of a bass drum by pressing the pedal itself.
2. Description of the Related Art
Conventionally, various foot pedals for a drum of such a kind have been proposed.
For example,
FIGS. 7
to
11
show a foot pedal for a drum which has been described in JP08-146946A and whose structure will briefly be explained below.
This foot pedal for a drum has been proposed for the purpose of setting a bass drum or the foot pedal at an angle (orientation) at which a player can play the best.
That is, in
FIGS. 7 and 8
, reference numeral
100
denotes a generally U-shaped frame, reference numerals
101
and
102
denote struts, reference numeral
103
denotes a bottom plate, reference numeral
104
denotes a shaft supported between the struts
101
,
102
, reference numeral
105
denotes a rocker fixed to the shaft
104
, reference numeral
106
denotes a beater mounted adjacent to the rocker
105
, reference numeral
107
denotes a spring for imparting a returning force to the shaft
104
, reference numeral
108
denotes a pressing force transmitting member, such as a chain, whose one end is fixed to an outer peripheral face of the rocker
105
, reference numeral
109
denotes a pedal which is coupled to the other end of the pressing force transmitting member
108
and whose heel side is supported by a shaft
110
, reference numeral
111
denotes a clamp metal fitting for fixing the whole foot pedal to a hoop of a bass drum, reference numeral
112
denotes a fixing screw for driving the clamp metal fitting
111
, and reference numeral
113
denotes an anchor screw for preventing the whole footpedal from displacing on a floor face.
Also, as shown in detail in
FIG. 8
, reference numeral
200
denotes a coupling plate whose rear end portion is fixed to a heel
114
of the pedal
109
by a screw
201
and whose front end portion is screwed to the bottom plate
103
of the frame
100
by a screw
202
.
Incidentally, reference numerals
203
and
204
denote creepers formed on a back face of the coupling plate
200
.
In the conventional foot pedal constituted in the above manner, the frame
100
is rotatable about the screw
202
relative to the coupling plate
200
.
Therefore, as shown in FIG.
9
and
FIG. 10
, in a state that the frame
100
has been fixed to the hoop
301
of the bass drum
300
by the clamp metal fitting
111
, the coupling plate
200
can be rotated together with the pedal
109
. Accordingly, for example, in case that the foot pedal is operated by the right foot of a player or a drummer, the pedal
109
can be set such that the heel
114
is directed inwardly in a state that a front face of the bass drum
300
is directed to an audience, as shown in FIG.
9
. Even in this case, the beater
106
can beat the drum head along a direction perpendicular thereto.
Since the conventional foot pedal has such a structure, the foot pedal
109
or the bass drum
300
can be set in an optimal orientation for a player or a drummer.
Incidentally,
FIG. 11
shows a structure for preventing the pressing force transmitting member
108
from being distorted.
In
FIG. 11
, reference numeral
115
denotes a fixing metal fitting which is mounted to one end portion of the pressing force transmitting member
108
, reference numeral
116
denotes a bolt, reference numeral
117
denotes a rotary plate, reference numeral
118
denotes a screw hole formed at one end portion of the pedal
109
. The pressing force transmitting member
108
and the pedal
109
are coupled to each other by sandwiching the fixing metal fitting
115
and the rotary plate
117
between the bolt
116
and the pedal
109
to screw the bolt
116
into the screw hole
118
.
According to this structure, since the pedal
109
is allowed to rotate relative to the pressing force transmitting member
108
slightly, consideration has been taken such that distortion does not occur in the pressing force transmitting member
108
even when the pedal
109
is set to the frame
100
at such a position that the former has been rotated relative to the latter, as shown in
FIG. 9
or
FIG. 10
,
According to the above-described conventional art, it is possible to set the pedal
109
at a desired angle (orientation) securely, but there are the following problems.
First of all, it is assumed that the frame
100
is rotated relative to the coupling plate
200
by a desired angle, and the whole foot pedal is fixed to the hoop
301
of the bass drum
300
by the clamp metal fitting
111
according to fastening of the screw
202
. In this state, when a player is not satisfied with the angle (orientation) of the pedal
109
and he/she wishes to adjust it finely, it is necessary to loosen the screw
202
, acting as a rotation center axis, which rotatably supports the frame
100
to the coupling plate
200
.
However, in order to loosen the screw
202
while the frame
100
remains fixed to the hoop
301
, it is necessary to lift this side (player side) of the bass drum
300
slightly to loosen the screw
202
from the underside of the coupling plate
200
(a floor face side) by a screw driver or the like, which requires an extremely complicated and troublesome work.
Also, when such means is not taken, a procedure including steps of loosening the screw
202
, adjusting a relative rotational angle between the frame
100
and the coupling plate
200
, and thereafter fixing the whole foot pedal to the hoop
301
by the clamp metal fitting
111
after the screw
202
is fastened again must be employed in a state that the whole foot pedal has been detached from the hoop
301
by releasing clamping conducted by the clamp metal fitting
111
.
Even in either case, conventionally, the angle (orientation) setting work for the pedal
109
is extremely complicated and difficult to conduct, and the foot pedal for a drum is inconvenient in use.
In view of the above problem, an object of the present invention is to provide a foot pedal for a drum which facilitates a setting work of an angle for a pedal and where convenience in use has been improved by performing various improvements.
SUMMARY OF THE INVENTION
In order to solve the above problem, according to a first aspect of the present invention, there is provided a foot pedal for a drum which beats a drum head by swinging a beater according to pressing of a pedal, comprising a heel which pivotally supports the pedal along a pressing direction of the pedal; and a base plate which has an arc-shaped guide groove allowing pivoting of the heel on a horizontal plane, wherein the pedal and the heel are pivotable integrally along the guide groove, and the heel can be fixed to the base plate at any position along the guide groove.
According to a second aspect of the invention, there is provided a foot pedal for a drum according to the first aspect, further comprising: a frame which is provided in a standing manner and fixed on a top face of the base plate; a shaft which is bridged between a pair of struts of the frame and to which a beater is fixed; a pressing force transmitting member which transmits a pressing of the pedal to the shaft to rotate the shaft and swing the beater; an angle adjusting member which is connected to an end of the pressing force transmitting member which is positioned on a side opposed to the shaft to pivotably support the pedal at a distal end portion thereof; a fixing screw for fixing the pedal to the angle adjusting member from the above; and another fixing screw for fixing the heel to the base plate from the above.
According to a third aspect of the invention, there is provided a foot pedal for a drum according to the second aspect, wherein the angle adjusting member has at least one angle adjusting face which comes in plane contact with an end face of the pedal to position the pedal.
According to a fourth aspect of the invention, there is provided a foot pedal for a drum according to any one of the first to third aspects, wherein the heel is formed so as to be movable on
