ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to a moveable holder structure for the foot pedal of a drum, and in particular, to a holder structure having protruded lugs on an urging element formed with a long slot and having a moveable pressing block forming a circular protruded block corresponding to the protruded lugs. The structure allows a rapid combination with the edge of a drum and also reduces the cost of manufacturing.
(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.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a moveable holder structure for the foot pedal of a drum, which improves the speed of combination of the structure onto a drum set to eliminate unnecessary steps.
Yet another object of the present invention to provide a moveable holder structure for the foot pedal of a drum, wherein the cost of manufacturing is lowered, and the products is more competitive.
A further object of the present invention to provide a moveable holder structure for the foot pedal of a drum, wherein the strength of the holding force is increased and the drum edge is protected.
One aspect of the present invention is to provide a moveable holder structure for the foot pedal of a drum having a base seat pivotally mounted with an urging element, one end of the foot pedal corresponding to the urging element being a locking bolt which urges the base seat such that the other end of the urging element is fastened to the drum edge, characterized in that the urging element, corresponding to one end of the drum edge, is pivotally mounted with a moveable block, and the end portion of the urging element is provided with two corresponding protruded lugs having a long slot, the two sides at the top of the moveable block form into a circular protruded block which is adapted to the long slot thereby a moveable holder structure for foot pedal of a drum which can be easily combined is obtained.
Other object and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawing.
