(b) Description of the Prior Art
FIGS. 1
,
2
A and
2
B show a conventional foot pedal
10
of a drum, and the pedal beats onto the surface of the drum (not shown) by means of a chain. The foot pedal
10
is mounted to the drum edge
40
of the big drum by means of a holding structure. The base seat
11
of the foot pedal
10
is pivotally mounted with a moveable urging element
12
which can move forward and backward. The urging element
12
, corresponding to one end of the inner side of the foot pedal
10
, is mounted with a locking blot
13
, and the other end of the urging element
12
is provided with two corresponding protruded lugs
14
respectively having a pivotal hole
140
. There is a pressing block
15
pivotally mounted in between the two protruded lugs
14
, and the top of the pressing block
15
is extended with a protruded block
16
having a pivotal hole
160
. A rivet
17
mounts in sequence into the protruded lugs
14
and the pivot holes
140
,
160
of the pressing lugs
14
and the protruded block
16
, and is then rivetted, such that the pressing block
15
is pivotally mounted to the urging element
12
. When the user rotates the locking bolt
13
to urge against the base seat
11
, the pressing block
15
and the base seat
11
of the other end of the urging element
12
are correspondingly fastened to the drum edge
40
.
This conventional holding structure has the following drawbacks:
1) In combination of the pressing block
15
, the pivotal hole
160
of the protruded block
16
has to be in alignment with the pivotal hole
140
of the protruded lug
14
. Next, the rivet
17
passes through the protruded lugs
14
and the pressing block
15
and the end of the rivot
17
is opened to allow the pressing block
15
to pivotally mounted onto the urging element
12
. The entire process of combination is complicated. Besides, after rivetting, it is not easy to be dismantled.
2) It requires more materials, time and tools in order to combine the pressing block
15
. Thus, the cost of combination is high and the time taken is comparatively longer.
3
) The pivotal holes
160
,
140
of the protruded block
16
and the protruded lugs
14
are mounted by means of rivet. The size of the pivotal holes
160
,
140
and the external diameter of the rivet
17
are of similar size without tolerance. If the pressing block
15
and the drum edge
40
are not in the located at the same level position, the pressing block
15
will press against the drum edge
40
at a single point. Thus, the holding force is affected and the drum edge
40
may be damaged. This will affect the sound output of the drum.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 3
,
4
A and
4
B, there is shown a moveable holder structure for the foot pedal of a drum, wherein the holder structure of the foot pedal
20
has an urging element
22
which can move forward and backward and is mounted at a base seat
21
of the foot pedal
20
. The urging element
22
, corresponding to one end of the inner side of the foot pedal
20
, and is provided with a locking bolt
23
which presses against the base seat
21
. The other end of the urging element
22
is pivotally mounted with a moveable block
25
. When the user rotates the locking bolt
23
to urge against the base seat
21
, the moveable block
25
of the urging element
22
faces downward, and together with the base seat
21
, these components correspond to the drum edge
40
.
Referring again to
FIGS. 3
,
4
A and
4
B, the urging element
22
, corresponding to one end of the moveable block
25
, is downwardly extended to form a pair of protruded lugs
24
. There is a long slot
240
formed on the protruded lugs
24
. The top surface of the moveable block
25
is provided with a positioning plate
26
which can be mounted in between the two protruded lugs
24
. The two lateral sides at the top surface of the moveable block
25
are respectively provided with a side plate
27
. The two side plates
27
are provided respectively with a circular protruded block
28
along the long slot
240
of the protruded lugs
24
, such that the moveable block
25
together with the circular protruded block
28
pivotally mounted to the protruded lugs
24
of the pressing element forms into the holder structure of the present invention.
FIGS. 3
,
4
A and
4
B show the operation of the present invention. When forming the moveable block
25
, the circular protruded block
28
on the side plate
27
is located to correspond to the protruded lugs
24
of the pressing element
22
. Next, the circular protruded block
28
is pushed towards the long slot
240
of the protruded lugs
24
. The elasticity of the side plates
27
and the arch-shaped surface of the protruded block
28
facilitate the protruded block
28
to slided into the long slot
240
. Thus, the moveable block
25
is combined. To dismantle the structure, the components are pulled apart. Thus, no other additional tools are required to proceed with the combination of the structure.
As the circular protruded block
28
is smaller than the long slot
240
of the protruded lug
24
, when the foot pedal
20
is to be locked at the drum edge
40
. The circular protruded block
28
can slide along the long slot
240
up and down. Thus, the block
25
is moveable. If the drum edge
40
is not at a level position, the moveable block
25
can automatically compensate the tilting angle to main a strong holding so as to avoid dislocation.
In another preferred embodiment of the present invention, and as shown in
FIG. 5
, the front end of the urging element
22
is pivotally mounted with a moveable block
30
. The moveable block
30
has a protruded block
31
at the top face thereof, and the two sides of the protruded block
31
are respectively provided with a notch
32
such that the two side walls of the protruded block
31
are with flexibility. Additionally, the two lateral walls of the protruded block
31
are respectively formed externally into a circular protruded block
33
. The two circular protruded blocks
33
are corresponding to the long slot
240
of the protruded lugs
240
. Thus the moveable block
30
is pivotally mounted to the urging element
22
and the protruded block
33
by means of the circular protruded block
33
. Due to the flexibility of the two lateral side walls of the protruded blocks and the arch-shaped surface of the circular protruded block
33
, the combination of the structure is attained.
In accordance with the present invention, there are advantages as follows
1) Quick Combination:
As the moveable block
25
makes use of the flexibility of the side plates
27
and the arch-shaped surface of the circular protruded block
28
to be pivotally mounted to the urging element
22
, this avoid the need of the rivetting process. Thus, the combination of the present structure is quick, and the effectiveness of the structure is improved.
2) Low Cost:
Due to the easy combination of the moveable block, unnecessary material and devices are not required, and no additional labour force is required. Thus, the entire cost of production is low.
3) Strong Holding Capability:
By using the circular protruded block
28
to move along the long slot
240
of the protruded lugs
24
, the moveable block
25
can be used on drum edge
40
with different tilting angle.
While the invention has been described with respect to preferred embodiment, it will be clear to those skilled in the art that modifications and improvements may be made to the invention without departing from the spirit and scope of the invention.
