(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.
